A node has one payload kind: - -- scalar value; -- list items; -- object fields. - -Nodes can also carry language metadata such as `name`, `description`, `type`, -`schema`, `itemType`, `keyType`, `valueType`, and `blueId`. - -```yaml -name: Counter -description: Small document with one integer field -counter: - type: Integer - value: 0 -``` - -The Java representation is `blue.language.model.Node`. It is mutable and useful -for parsing, authoring, serialization, and compatibility APIs. - -### Types - -In Blue, a type is also a Blue node. A document with `type` inherits and must -conform to that type. - -```yaml -name: Price -amount: - type: Integer -currency: - type: Text -``` - -An instance can point to the type by BlueId: - -```yaml -type: - blueId: -amount: 150 -currency: EUR -``` - -Resolving the instance makes inherited fields, type metadata, and constraints -available in the runtime view. - -### BlueIds - -A BlueId is a deterministic content address. It is calculated from canonical -Blue content using RFC 8785-style canonical JSON input and SHA-256/Base58 -output. - -In canonical Blue, `{ blueId: X }` is a pure reference. It cannot be mixed with -sibling content: - -```yaml -# valid -type: - blueId: 4th6... - -# invalid -type: - blueId: 4th6... - name: Price -``` - -This keeps reference identity unambiguous. - -### Canonical Versus Resolved - -Blue distinguishes two useful views: - -- canonical content: minimized content used for identity and storage; -- resolved content: runtime view with inherited type state available. - -`ResolvedSnapshot` contains both views as immutable `FrozenNode` graphs: - -```text -ResolvedSnapshot - canonicalRoot -> minimized identity source - resolvedRoot -> runtime view - blueId -> canonicalRoot.blueId() -``` - -Use snapshots for hot processing paths. Use mutable `Node` values at the edges -where you parse, serialize, or build documents programmatically. - -## Quick Start - -### Parse YAML And Serialize It Back - -```java -import blue.language.Blue; -import blue.language.model.Node; - -Blue blue = new Blue(); - -Node node = blue.yamlToNode( - "name: Counter\n" + - "counter: 0\n"); - -String json = blue.nodeToJson(node); -String yaml = blue.nodeToYaml(node); - -System.out.println(json); -System.out.println(yaml); -``` - -### Compute A Structural BlueId - -Use `calculateBlueId` when the node itself is the content you want to address. - -```java -String blueId = blue.calculateBlueId(node); -System.out.println(blueId); -``` - -Structural BlueIds are sensitive to authored content. If a document contains a -redundant inherited override, that override is part of the structural input. - -### Compute A Semantic BlueId - -Use `calculateSemanticBlueId` when you want identity after preprocess, resolve, -and minimization. - -```java -String semanticBlueId = blue.calculateSemanticBlueId(node); -System.out.println(semanticBlueId); -``` - -Semantic identity is useful when different authored forms should be treated as -the same document because they resolve to the same minimized meaning. - -## Reference Providers - -Blue resolves `{ blueId: ... }` references through a `NodeProvider`. - -For tests and local tools, `BasicNodeProvider` is often enough: - -```java -import blue.language.Blue; -import blue.language.model.Node; -import blue.language.provider.BasicNodeProvider; - -Blue bootstrap = new Blue(); - -Node priceType = bootstrap.yamlToNode( - "name: Price\n" + - "amount:\n" + - " type: Integer\n" + - "currency:\n" + - " type: Text\n"); - -BasicNodeProvider provider = new BasicNodeProvider(priceType); -String priceTypeBlueId = provider.getBlueIdByName("Price"); - -Blue blue = new Blue(provider); - -Node price = blue.yamlToNode( - "type:\n" + - " blueId: " + priceTypeBlueId + "\n" + - "amount: 150\n" + - "currency: EUR\n"); - -Node resolved = blue.resolve(price); -System.out.println(blue.nodeToYaml(resolved)); -``` - -For production storage, implement `NodeProvider`: - -```java -import blue.language.NodeProvider; -import blue.language.model.Node; - -import java.util.Collections; -import java.util.List; - -public final class DatabaseNodeProvider implements NodeProvider { - private final BlueDocumentStore store; - - public DatabaseNodeProvider(BlueDocumentStore store) { - this.store = store; - } - - @Override - public List fetchByBlueId(String blueId) { - Node content = store.fetchCanonicalNode(blueId); - return content == null ? Collections.emptyList() : Collections.singletonList(content); - } + implementation 'blue.language:blue-language-java:3.1.0-rc.18' } ``` -The provider should return canonical Blue content for a requested BlueId. The -library wraps providers internally to support single-document and multi-document -reference forms. - -## Schema - -`schema` provides deterministic core validation. Supported keywords include: - -- `required` -- `minLength` -- `maxLength` -- `minimum` -- `maximum` -- `exclusiveMinimum` -- `exclusiveMaximum` -- `multipleOf` -- `minItems` -- `maxItems` -- `uniqueItems` -- `minFields` -- `maxFields` -- `enum` - -Example: - -```yaml -name: Product -sku: - type: Text - schema: - required: true - minLength: 3 - maxLength: 32 -quantity: - type: Integer - schema: - minimum: 0 -``` - -## Lists - -Blue list resolution supports overlays over inherited lists. - -### Positional Overlay - -```yaml -type: - blueId: -items: - - $previous: - blueId: - - $pos: 1 - value: replacement - - value: appended -``` - -`$previous` anchors the inherited list. `$pos` replaces a specific inherited -position. Normal items after the overlay append to the result. - -### Empty List Placeholder - -```yaml -items: - - $empty: true -``` - -`$empty: true` is content. It is not the same as an absent list. - -### Merge Policies - -```yaml -type: List -mergePolicy: append-only -items: - - value: first -``` - -Supported list policies: - -- `positional` -- `append-only` - -The resolver, minimizer, and BlueId calculator all understand these list-control -forms. - -## Immutable Snapshots - -`ResolvedSnapshot` is the preferred runtime representation. - -```java -import blue.language.snapshot.ResolvedSnapshot; - -ResolvedSnapshot snapshot = blue.resolveToSnapshot(price); - -System.out.println(snapshot.blueId()); -System.out.println(snapshot.frozenCanonicalRoot().blueId()); -System.out.println(snapshot.frozenResolvedRoot().blueId()); -``` - -Snapshots provide: - -- immutable canonical root; -- immutable resolved root; -- cached per-node BlueIds; -- path indexes for fast reads; -- structural sharing for resolved references and type graphs. - -Read a node by JSON Pointer: - -```java -import blue.language.snapshot.FrozenNode; - -FrozenNode amount = snapshot.resolvedAt("/amount"); -System.out.println(amount.getValue()); -``` - -Use JSON Pointer escaping for literal `/` and `~` in field names: - -```java -FrozenNode value = snapshot.resolvedAt("/a~1b/c~0d"); -``` - -This addresses the object path: - -```yaml -a/b: - c~d: value -``` - -## Snapshot Caches - -`Blue` keeps a resolved snapshot cache and a resolved reference cache. - -```java -ResolvedSnapshot first = blue.resolveToSnapshot(price); -ResolvedSnapshot second = blue.loadSnapshot(first.blueId()); - -System.out.println(first == second); // true when loaded from the in-memory cache -System.out.println(blue.resolvedSnapshotCacheSize()); -System.out.println(blue.resolvedReferenceCacheSize()); -``` - -You can preload snapshots at startup: - -```java -blue.cacheResolvedSnapshot(first); -``` - -Cache hits improve performance but do not change document identity or processor -gas accounting. - -Cache bounds are selected per `Blue` runtime: - -```java -Blue serviceRuntime = Blue.withCachePolicy(BlueCachePolicy.lowMemoryDefaults()); -Blue batchRuntime = Blue.withCachePolicy(BlueCachePolicy.highThroughputDefaults()); -Blue noReloadableCaches = Blue.withCachePolicy(BlueCachePolicy.disabled()); -``` - -`boundedDefaults()` is the conservative production default. `disabled()` turns -off reloadable acceleration caches while preserving snapshots explicitly pinned -with `cacheResolvedSnapshot(...)`. - -## Dictionary-Aware Export - -A dictionary is a named collection of known Blue type definitions. When you send -a document to another system, that system may tell you which dictionaries it -understands. The exporter can then keep supported types as compact BlueId -references and inline unsupported type definitions so the receiver still gets a -self-describing document. - -Register dictionaries through the generic `TypeDictionary` SPI: - -```java -import blue.language.dictionary.TypeDictionary; - -blue.registerTypeDictionary(myDictionary); -``` - -Export for a receiver that supports one dictionary version: - -```java -import blue.language.dictionary.ExportContext; - -ExportContext context = ExportContext.builder() - .dictionary("example.types", "ExampleDictionaryBlueId") - .build(); - -String yaml = blue.nodeToYaml(document, context); -String json = blue.nodeToJson(document, context); -``` - -If a referenced type belongs to `example.types` and is representable by -`ExampleDictionaryBlueId`, the exported document keeps the compact reference: - -```yaml -request: - type: - blueId: -``` - -If a referenced type is known locally but not supported by the receiver, the -exporter inlines the current type definition: - -```yaml -request: - type: - name: Custom Request - amount: - type: - blueId: - memo: - type: - blueId: -``` +Or select only the focused artifacts you use: -Inlining is recursive and cycle-checked.

The frozen matcher avoids mutable traversal entirely and reuses -provider-backed references through local caches. - -Important matching rules: - -- `name` and `description` are labels, not type-compatibility constraints; -- pure reference pattern leaves are exact identity checks; -- extra candidate fields are allowed unless the pattern/schema forbids them; -- list and dictionary payload kinds are checked explicitly; -- missing optional target fields are allowed unless they carry meaningful - requirements such as `schema.required: true`. - -## Canonical Patching - -Canonical patches operate on immutable roots and return new snapshots. - -```java -import blue.language.processor.model.JsonPatch; -import blue.language.snapshot.ResolvedSnapshot; - -ResolvedSnapshot before = blue.resolveToSnapshot(price); - -JsonPatch patch = JsonPatch.replace("/amount", new Node().value(200)); -ResolvedSnapshot after = blue.applyCanonicalPatch(before, patch); - -System.out.println(after.blueId()); -``` - -Supported patch operations: - -- `JsonPatch.add(path, value)` -- `JsonPatch.replace(path, value)` -- `JsonPatch.remove(path)` - -Patch paths are JSON Pointers.

Status and purpose + +This file defines every non-Blue control accepted by the fixture envelope `blue-contracts-fixture/1.0`. It is normative for the conformance package. A runner MUST reject any control field not declared by `fixture-schema.yaml` and this document. + +Controls prepare exact inputs or deterministic fixture implementations. They never bypass `PROCESS`, write the result directly, suppress required validation, or alter portable gas merely because a fixture requested a scenario. + +## 2. Preparation order + +For `process`, `process-attempt`, and `platform`, the runner performs these steps in order: + +1. Parse the fixture under `fixture-schema.yaml`. +2. Apply `input.builders` to a private copy of `input.root`. +3. Parse and validate the resulting Root and `input.event` as Blue Language 1.0 values. +4. Verify every `input.provider.nodes` entry against its map key. +5. Load the exact fixture runtime registry named by `runtime.typeRegistryManifest`. +6. Install the deterministic scripted implementations described below. +7. Derive the full canonical ExternalDelivery snapshot from Root, event, intervals, and registry. +8. Check every `feeder.deliverySnapshot` hint against that derivation. +9. Invoke the selected fixture operation. +10. Evaluate assertions against the closed projection catalog. + +A builder or runtime script that creates invalid Blue content causes the same deterministic admission or runtime failure that ordinary content would cause. + +## 3. Builders + +Builders exist only to avoid committing megabytes of repetitive literal YAML. Their expansion is deterministic and occurs before Blue parsing. The `kind` field selects exactly one builder algorithm from the table below. + +| Kind | Required fields | Exact expansion | +|---|---|---| +| `generated-object` | `target`, `memberCount`, `keyPrefix`, `value` | Set `target` to an object with keys `keyPrefix + zero-padded decimal index`, for indexes `0..memberCount-1`, each containing a deep copy of `value`. Padding width is the decimal width of `memberCount - 1`, with width one for an empty or one-item object. | +| `generated-list` | `target`, `itemCount`, `item` | Set `target` to a list of `itemCount` deep copies of `item`. | +| `repeated-text` | `target`, `codePointCount`, `text` | `text` MUST contain exactly one Unicode code point. Set `target` to that code point repeated `codePointCount` times. | + +The target is an RFC 6901 pointer. Missing intermediate objects are created. Existing scalar/list intermediates are an invalid fixture. + +## 4. Provider controls + +`mode: exact-node` means each provider map key is a plain BlueId and each value is exact BlueId Input whose Node BlueId MUST equal that key. + +`semanticDemandsOnly: true` prohibits physical cache/page/chunk observations from appearing in portable traces. + +`transientUnavailableAt` names one canonical demand phase or exact demanded BlueId. The first matching demand produces `PROCESS_ATTEMPT -> NeedsResources`; no `ProcessResult`, progress, state, events, or portable gas exists for that attempt. + +## 5. Runtime controls + +### 5.1 `handlers` + +The key is an absolute Root pointer to a fixture `ScriptedHandler`. Its `result` is returned when—and only when—the ordinary Contracts processor selects and executes that exact Handler. Patches, events, termination, failures, and named runtime counters pass through normal result normalization, boundary checks, charging, cascades, checkpointing, and rollback. + +### 5.2 `initializationPatches` + +Installs one fixture Lifecycle Handler at every participating scope selected by the fixture. It returns the listed patches only for `Document Processing Initiated`. The patches are not host writes. + +### 5.3 `childEmissions` + +Installs one selected child Handler that emits the listed values in list order. The values enter the ordinary internal EventOccurrence queue. + +### 5.4 `rootForwardAll` + +Installs a Root Embedded Node Handler that explicitly re-emits every received descendant event once, preserving order and multiplicity. This is application behavior; descendant events are not public without this handler. + +### 5.5 `nestedEnqueues` + +Installs a deterministic Triggered Handler that emits the next numbered fixture event until exactly `nestedEnqueues` events have been enqueued. It exercises queue order and limits through normal event delivery. + +### 5.6 `cascadeMutation` + +This control installs fixture Document Update or Lifecycle Handlers that perform the named mutation at the named causal point: + +- `afterPatchIndex`: zero-based patch index after whose complete update cascade the mutation runs; +- `replaceScope`: exact embedded scope root replaced by a valid fixture replacement node; +- `thenReaddSamePath`: after replacement/removal, add a fresh node at the same path during the same invocation; +- `replaceScopeDuringLifecycle`: perform replacement while the selected lifecycle delivery is active; +- `sourceCutOffDuringUpdate`: replace/remove the update source scope while its update is propagating. + +These handlers are processed normally and are the only cause of the mutation. The control never mutates run state directly. + +### 5.7 Generalization controls + +`generalizationCandidates` is the exact existing ancestor chain supplied by the fixture type provider, most-specific first. `validCandidate` is the first candidate whose fixture validation function returns valid. The runner MUST still execute the normative nearest-valid-ancestor algorithm and report its candidate order. + +### 5.8 Termination controls + +`terminationRequests` installs ordered fixture results that request successful graceful termination with the supplied application `cause` and optional `reason`. The first request wins. + +`gasLimitDuringTermination: true` selects the smallest fixture gas limit that admits the preceding work but rejects the next canonical termination charge. It is a shorthand for a precisely derived limit, not host intervention during execution. + +`gasLimit` directly sets the invocation limit for that fixture. + +## 6. Feeder controls + +`managedRootRevision`, `indexedRootRevision`, and `eventOrderKey` are exact platform state for the attempt. + +### 6.1 Delivery snapshot hints + +`deliverySnapshot` is a compact fixture hint, not the normative `ExternalDelivery` value. Each hint contains `scopePath`, `channelKey`, optional asserted `order`, and optional interval frontier. The runner MUST independently derive the full snapshot: + +```text +scopePath +channelKey +orderedSourceContributionNodeBlueIds +effectiveTypeBlueId +order +checkpointDomainBlueId +``` + +It then verifies that the hints identify exactly the same ordered occurrences and that any supplied order/frontier agrees. A hint never supplies missing identity fields to `PROCESS`. + +Every non-root scope path must be reachable at each ancestor through either an effective exact `Process Embedded.paths` declaration or one concrete direct object member generated from an effective `Process Embedded.collectionPaths` declaration. Every selected scope must contain the named effective External Channel. The validator performs this check for fixture content that is statically available. + +For collection declarations, the runner reads the complete direct ordinary member-key set, orders keys by Unicode code point, escapes each key as one Runtime Pointer segment, and derives concrete paths. A compact hint always names the resulting concrete path. The runner MUST reject list targets, non-object members, duplicate/overlapping declarations, wildcard syntax, reserved-field traversal, and cyclic-member boundaries. + +### 6.2 Remaining feeder controls + +| Control | Exact meaning | +|---|---| +| `canonicalPreselection` | Expected compact occurrence hints after raw-index filtering and before complete acceptance. | +| `rawIndexCandidates` | Physical over-approximation returned by the fixture index. False positives are permitted; omissions are not. | +| `acceptanceStateVariants` | Root-state cases used only to prove that immutable External Channel acceptance does not depend on mutable business state. | +| `channelLawCases` | Truth table rows checked against `ACCEPTS => PRESELECTS => key intersection`. | +| `currentEventAddsChannel` | The event's successful transition adds a new channel; it begins strictly after the current event key and cannot join the current snapshot. | +| `intervalHistory` | Ordered add/remove/re-add actions used to derive fresh activation intervals. | +| `targetsByEvent` | Exact retained target order for each queued external event. | +| `eventQueue` | External events waiting at the feeder; one event's retained delivery set must reach terminal progress before the next begins. | +| `evaluatedRevision` | Root revision against which a terminal outcome was calculated. | +| `casConflict` | The final compare-and-swap fails because the current Root revision differs. No portable gas is added by the conflicted persistence attempt. | +| `sameFailureCount` | Number of identical revision-bound failures already recorded for the quarantine-policy fixture. | + +## 7. Variants + +Every variant is a complete deterministic transformation of the base input: + +- `rootForm`: inline, pure reference, eager materialization, or lazy materialization of the same exact node; +- `cache`: warm/cold physical provider state, never semantic evidence; +- `batching`: batched/unbatched physical retrieval; +- `accept`: replace the fixture channel's immutable `accept` header; +- `checkpointSubject`: replace the exact subject returned by the fixture channel function; +- `listOperation`: run the declared append or head-replacement identity scenario; +- `newEmbeddedSurface`: exact replacement value for the changed embedded declarations; +- `rootRevision`: use the stated managed Root revision; +- `sameEvent`: retain the exact event identity when testing retries. + +A variant name alone has no semantics; every variant object MUST declare the transformation fields it uses. + +## 8. `gas-micro` + +A gas microfixture does not execute `PROCESS` unless it explicitly provides Root/event/runtime controls. Its input describes one counter or formula. Its expected trace and total are exact. Unknown counter/formula inputs fail closed. + +## 9. Scripted External Channel dependency and routing fields + +The conformance-only `Scripted External Channel` registry type implements the generic same-scope Channel dependency and logical-delivery laws from Contracts §3.3. + +Its Blue fields have these exact meanings: + +| Field | Semantics | +|---|---| +| `dependencyMode: none` or absent | Declares no peer Channel dependency. Event-time lookup of another key is forbidden. | +| `dependencyMode: exact` | Declares exactly `dependentChannelKey`; event-time lookup is permitted only for that raw same-scope key. | +| `dependencyMode: catalog` | Declares the bounded complete same-scope Channel header catalog. Event-time exact-key lookup is allowed against that frozen catalog. | +| `handlerChannelKey` | Requested same-scope Channel used for Handler binding after the source accepts. It does not become an external source and receives no source checkpoint. | +| `logicalDeliveryKey` | Logical grouping key. When absent, the raw source channel key is used. | +| `fallbackToSourceOnAbsentOrNonChannel` | If true and lookup yields `ABSENT` or `NON_CHANNEL`, the raw source key remains the Handler Channel. If false, the fixture source rejects the delivery. Incomplete or undeclared evidence never falls back. | + +The scripted implementation derives payload, checkpoint domain, checkpoint subject, target key, and logical-delivery key from immutable header fields and the exact event. It does not inspect mutable business fields. Several fresh sources in one `(scopePath, logicalDeliveryKey)` group execute Handlers once only when their exact payload and target identities agree. Each fresh source retains its own checkpoint authority. + + +## 11. Exact participant bindings and parent lookup + +Fixtures may place the same exact Channel node inline or behind a pure BlueId reference. The runner MUST treat these forms identically after exact verification. It MUST NOT import a parent or ancestor Channel into an embedded scope merely because the raw key is equal. The fixture runtime has no implicit Parent Channel feature. diff --git a/blue-conformance/src/main/resources/blue-contracts-1.0/fixtures/HARNESS.md b/blue-conformance/src/main/resources/blue-contracts-1.0/fixtures/HARNESS.md new file mode 100644 index 00000000..0c04da40 --- /dev/null +++ b/blue-conformance/src/main/resources/blue-contracts-1.0/fixtures/HARNESS.md @@ -0,0 +1,180 @@ +# Blue Contracts 1.0 fixture harness + +## 1.

Canonical delivery derivation + +For each delivery hint, the runner MUST derive and retain: + +```text +scopePath +channelKey +orderedSourceContributionNodeBlueIds +effectiveTypeBlueId +order +checkpointDomainBlueId +``` + +It MUST verify: + +1. every non-root path is transitively declared through either an exact `Process Embedded.paths` entry or a concrete direct member generated from `Process Embedded.collectionPaths`; +2. the selected scope exists as an object and is not under a direct terminated scope; +3. the effective contract at `channelKey` is an External Channel; +4. any asserted `order` and activation frontier agree with the derived state; +5. the complete ordered hint set equals the canonical preselected occurrence set for the fixture. + +The compact hints do not substitute for missing identity fields and are never passed to application contracts. + +## 6. Projections + +The only legal assertion paths are listed in `projection-catalog.yaml`. + +Projection families are: + +- `result.*`: public `ProcessResult`; +- `attempt.*`: alternate `PROCESS_ATTEMPT` result; +- `trace.*`: canonical semantic and gas trace; +- `demands.*`: logical semantic demands; +- `feeder.*`: canonical feeder derivations; +- `commit.*`: revision-bound persistence decision; +- `platform.*`: platform terminal state; +- `variants.*`: exact named variant outputs. + +A dot path selects an object field. Decimal segments select list positions. Braced paths such as `result.{status,document,events,totalGas}` select the fields in the written order. A missing declared projection fails the fixture unless the assertion operator is `absent`. + +## 7. Assertions + +Supported operators are: + +- `equals`, `notEquals`: exact semantic equality or inequality; +- `equalsProjection`: compare `actual` with the projection named by `expectedProjection`; +- `absent`, `present`: exact projection absence or presence; +- `sequenceEquals`: ordered equality preserving duplicates; +- `contains`, `notContains`: containment in the selected value; +- `lessThan`, `greaterThan`: exact numeric comparison; +- `sameAcrossVariants`: exact equality across every declared variant; +- `failsWith`: exact deterministic diagnostic category; +- `all`, `none`: universal or empty predicate over the selected projection. + +A string written in `expected` is always a literal string. Projection comparison MUST use `expectedProjection`; implicit strings such as `input.root` are forbidden. + +`ordered: true` requires the expected elements to occur in the listed relative order. `variant` restricts an assertion to the named exact variant. + +## 8. Trace model + +`TRACE-SCHEMA.md` defines the canonical named entry, logical demand record, and every derived trace. `trace.namedEntries` is the authoritative gas trace.

Purpose + +The harness executes the exact Language fixture set bound by `manifest.yaml`. Fixtures are normative executable cases, not examples. A conforming runner MUST implement every operation used by this package, verify provider evidence, preserve exact identity, and fail closed on unsupported fixture data. + +## 2. General rules + +- YAML is parsed under the Blue Language JSON-data-model restrictions. +- `input`, `source`, `parent`, `pattern`, `candidate`, `documents`, and provider nodes are Blue Source or BlueId-input values according to the named operation. +- Exact expected BlueIds are canonical Base58 encodings of 32-byte SHA-256 digests, except explicit cyclic member identities and fixtures whose purpose is invalid-BlueId rejection. +- `expectError: true` requires failure. `expectedErrorCategory` requires the exact category. Where only failure is asserted, the runner must still reject the input deterministically. +- Equivalent forms must produce the same semantic result or identity without being normalized through implementation-specific shortcuts. +- Unknown fixture fields or operations are runner failures. + +## 3. BlueId operations + +### `calculateBlueId` + +Normalize valid direct BlueId input and calculate one Node BlueId. `alsoEquivalentTo` values must produce the same ID. `alsoDifferentFrom` values must produce different IDs. + +### `calculateBlueIdPair` + +Calculate both exact inputs independently and compare them using `expectedEqual`. + +### `parseBlueIdInput` + +Validate direct BlueId input without running Source preprocessing. Invalid numeric tokens, unresolved aliases, mixed reference shapes, list controls, or other prohibited content must fail. + +## 4. Preprocessing, resolution, and validation + +### `parseSource` + +Parse a Source value while preserving the required token distinctions and exact Blue data model. + +### `preprocess` + +Apply the exact §6 pipeline: + +1. resolve and verify the effective root `blue` directive, including pure-reference directives and reference-backed `imports` or `transformations`; +2. establish the effective import map and supported transformation implementations without mutating the Source Document; +3. remove the root `blue` field; +4. execute declared transformations exactly once each in list order; +5. apply mandatory wrapper, placeholder, alias, and primitive-inference baseline normalization; +6. validate the resulting Preprocessed Document. + +`preprocessingAliases`, when present, is a closed test-environment map from a string-valued `blue` alias to one exact directive BlueId. The runner MUST configure those bindings before preprocessing. An unbound alias fails. + +The fixture package's `preprocessing/registry` directory defines three conformance-only transformation types and exact processor behavior. They are fixture support, not canonical Language core types. The runner MUST register only those exact types while running this package and MUST fail closed for any unsupported transformation type. + +`alsoEquivalentTo`, when present on a `preprocess` fixture, is independently preprocessed under the same provider, alias bindings, and transformation registry and MUST produce the exact same result as `source`. + +`expectedIdempotent: true` requires preprocessing the completed output again and obtaining the exact same node. + +Compare the final result with `expectedPreprocessed`. + +### `resolve` + +Preprocess, resolve the effective type chain, merge overlays, validate schemas and fixed values, and compare `expectedResolved`, `expectedValue`, `expectedEffectiveType`, or the expected failure. + +### `resolveVariants` + +Apply the same parent, declaration, provider, or base inputs to every variant independently and check each variant's expected validity, result, or error. + +### `resolveLimited` + +Resolve only the demanded paths within the declared limits. Return an explicit established, absent, incomplete, or invalid conclusion; never turn missing evidence into absence. Every established path must equal complete resolution for value, effective type, accumulated constraints, and provenance required by canonicalization. + +### `validate` and `validateVariants` + +Run the specified schema, type, collection, or dictionary validation without changing identity semantics. Variant order is fixture order. + +### `match` + +Apply matcher-neutral label behavior and typed semantic matching, then compare `expectedMatch` and any identity assertion. + +## 5. Canonicalization and minimization + +### `canonicalize` + +Resolve the Source value completely and derive the unique Canonical Identity Input. Compare `expectedCanonicalOverlay`, canonical items, control absence, and expected Content BlueId fields where supplied. + +### `compareContentAndDirectResolvedBlueId` + +Prove that Content BlueId is the Node BlueId of Canonical Identity Input and that directly hashing a noncanonical Resolved View need not yield it. + +### `minimizeAndResolve` + +Produce a valid author-facing Minimized Overlay, allow only the fixture-listed optional controls, and resolve it again. The second resolution MUST reproduce the expected complete Resolved Form or resolved items. + +When `expectedSameContentBlueIdThroughPipeline: true` is present, the runner MUST calculate the Content BlueId of both the original Source meaning and the produced Minimized Overlay by running each through the complete pipeline: + +```text +preprocess -> complete resolve -> canonicalize -> Node BlueId +``` + +The two Content BlueIds MUST be equal. The runner MUST NOT establish this assertion by directly hashing the Minimized Overlay, because minimization is not part of Content BlueId calculation and the minimized Source may contain controls such as `$previous`, `$pos`, or `$replace`. + +### `canonicalizeLimitedResult` + +Reject canonicalization when the supplied limited result is incomplete. + +## 6. Expansion, collapse, providers, and direct manifests + +Provider entries identify a requested BlueId and one of: + +```text +node or returnedNode +outcome: NotFound | Unavailable | InvalidEvidence +``` + +Every supplied node must verify under the operation's declared provider mode. A provider result cannot make unknown content absent. + +### `expand`, `expandLimited`, `expandVariants`, `compareExpansionStrategies` + +Expand only demanded references. Honor `limits`, `expectedRequestedBlueIds`, `expectedNotRequestedBlueIds`, expected descendant requests, and representation-equivalence assertions. Physical prefetch must not change semantic coverage. + +### `collapse` and `expandThenCollapse` + +Collapse only verified exact nodes to pure references, never mixed `blueId` forms, and preserve Node BlueId through the requested round trip. + +### `verifyDirectNode` and `verifyDirectList` + +Verify a complete direct object manifest or ordered direct list-element identities without demanding transitive child bodies. Direct completeness is required for semantic absence. + +### `retrieveDirectList` + +A list-prefix optimization may accelerate a fold but does not replace the complete ordered direct element-identity manifest returned to the semantic caller. + +### `semanticExists` + +Return `Established`, `Absent`, `Incomplete`, or `Invalid` as the fixture requests. Missing direct evidence, limits, and provider unavailability never prove absence. + +### `compareGraphEquivalentInputs` + +Run every representation against the same semantic demand and compare outcome, value, and exact root identity. + +### `compareLimitedAndCompleteResolution` + +The limited operation must equal complete resolution on every established path, including value, effective type, and constraints. + +## 7. Circular-set operations + +### `calculateCircularSetBlueIds` + +Execute the complete ZERO_BLUEID, preliminary-ID ordering, `this#i`, MASTER, and final member-ID algorithm. Duplicate preliminary members follow the exact rejection/disambiguation rule. + +### `expandCyclicMember` + +Reject isolated member verification and succeed only with a verified complete cyclic-set context. + +## 8. Registry, suite, path, and lint operations + +### `registryNodeHashesToPublishedBlueId` + +Load the exact registry file named by `registryKey`, calculate its Node BlueId, and compare the published ID. Do not recreate the node from Java constants. + +### `changingRegistryDescriptionChangesBlueId` + +Apply the exact identity-bearing mutation and prove the BlueId changes. + +### `suiteAssertion` + +Evaluate the meta-condition over the complete fixture inventory. It cannot be satisfied by a hard-coded `pass` result. + +### `assertViewPath` + +Apply RFC 6901 over the abstract Blue node model, including empty-string root and `/` empty-key behavior. + +### `lintPublishableDocumentation` + +Join every forbidden token sequence exactly as declared, inspect every declared publishable file, and reject any forbidden occurrence or missing required heading. + +## 9. Expected fields + +Expected fields are exact and operation-specific. Common forms include: + +```text +expectedNodeBlueId +expectedPublishedBlueId +expectedBlueIds +expectedPreprocessed +expectedResolved +expectedCanonicalOverlay +expectedValue +expectedValid +expectedOutcome +expectedRequestedBlueIds +expectedNotRequestedBlueIds +expectedErrorCategory +``` + +Lists preserve order unless the Language rule explicitly defines a set. A fixture runner MUST compare complete expected structures, not selected convenient fields. + +## 10. Preprocessing transformation fixture registry + +The support registry at `preprocessing/registry/manifest.yaml` binds exact fixture-only transformation type BlueIds. Its `HARNESS.md` defines the closed configuration and behavior for: + +```text +Rename Root Field Transformation +Set Root Field Transformation +Append Root Text Transformation +``` + +The harness MUST load the exact registry files, verify their BlueIds, and register their deterministic processors. Transformation selection is by exact type BlueId, never by `name`. Transformation items may be inline or pure references. All provider content must verify before execution. + +These fixture-only types do not imply that Blue Language 1.0 standardizes a universal field-renaming, field-setting, or text-append transformation catalog. They test the generic directive and transformation mechanism. + +## 11. Package integrity + +`manifest.yaml` is the authoritative inventory for this fixture package. It lists every behavior fixture and every support file with its relative path, role, LF-normalized byte length, and SHA-256 digest. It also binds the exact Language core-registry package identity and the exact vector-coverage map. + +The fixture-package identity is calculated as: + +```text +sha256( + UTF-8 canonical JSON of manifest.yaml + with packageIdentity set to null + and object keys sorted lexicographically +) +``` + +The manifest's `files` list is itself identity-bearing and is sorted by relative path. A fixture or support file that is added, removed, renamed, or changed requires a new manifest and fixture-package identity. The registry manifest binds this fixture package informationally; its own package identity deliberately excludes that reverse binding to avoid an identity cycle. + +## 12. Exact graph fragment operations + +### `splitExactGraphFragments` + +Admit the exact Root, apply every RFC 6901 cut in `cuts`, and produce ordinary Blue fragments. A cut materializes its selected node and replaces complete cut children by pure references to their exact Node BlueIds. The harness MUST: + +- calculate and verify every fragment identity; +- preserve canonical direct-child order; +- expose original, direct-fragment, and pure-reference Root representations; +- prove all Root representations have the same exact Root Node BlueId; +- expand the fragment graph back to the original exact Root; +- serve defensive copies from the local exact-node provider; +- return `NotFound` for every identity not admitted by that provider. + +This is a conformance utility over ordinary expansion and collapse. It does not define a new node form or partial identity. + +### `verifyOpaqueCyclicFragment` + +Admit an ordinary exact Root containing one or more finalized cyclic member references of the form `MASTER#index`. The fragmenter MUST preserve each member identity as an opaque edge, MUST NOT hash a member body independently, and MUST return `NotFound` from the ordinary local fragment provider for the member identity. Expansion may succeed only when a composed cyclic-aware provider supplies complete owning-set proof. diff --git a/blue-conformance/src/main/resources/blue-language-1.0/fixtures/README.md b/blue-conformance/src/main/resources/blue-language-1.0/fixtures/README.md new file mode 100644 index 00000000..252b89f6 --- /dev/null +++ b/blue-conformance/src/main/resources/blue-language-1.0/fixtures/README.md @@ -0,0 +1,7 @@ +# Blue Language 1.0 conformance fixtures + +This directory is the machine-readable conformance package for Blue Language 1.0.

Blue Contracts describe how one exact rooted reality becomes another exact rooted reality when something happens. + +## Conventions + +The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, **SHOULD NOT**, **MAY**, and **OPTIONAL** are normative requirement levels. + +Sections marked **normative** define required behavior. Sections marked **informative** explain intent or implementation guidance. + +The term **Language** means Blue Language Specification 1.0. + +--- + +## 0. Overview + +### 0.1 One root is one reality + +Every invocation has one authoritative root document. + +```text +Root +├── Customer +├── Payment +├── Delivery +└── Risk Monitor + └── External Review +``` + +Declared embedded documents are owned parts of that rooted reality. They may contain their own contracts, channels, lifecycle state, and internal events, but they are not independently committed sessions. A successful transition creates one new Root. Changed embedded nodes and every changed ancestor on their paths receive new BlueIds. Unchanged branches retain their existing BlueIds. + +An independently evolving or shared business object is modeled as another autonomous root connected by references and events. It is not modeled as one mutable embedded occurrence owned simultaneously by several roots. + +### 0.2 Processor boundary + +The normative operation is: + +```text +PROCESS(document, event) -> ProcessResult +``` + +where: + +- `document` is the exact current Root; +- `event` is the exact next external event selected by the managing feeder; +- `ProcessResult.document` is the exact resulting Root; +- `ProcessResult.events` contains only events emitted by the Root scope; +- `ProcessResult.totalGas` is the deterministic logical work admitted by the invocation; +- every tentative effect either commits in the one Root transition or is discarded. + +There is no authored target path, `deliveryOccurrence`, child session, Embedded Child Commit, or public effect log in the processing API. + +### 0.3 Feeder and processor + +The managing feeder connects external time to deterministic processing. + +```text +Feeder: + observes every active external channel declared by Root and embedded scopes; + maintains a revision-complete incremental subscription index; + obtains externally ordered entries and source-completeness evidence; + orders external events deterministically; + derives the exact channel-occurrence snapshot for the next event; + makes the selected graph branches and verified nodes available; + commits Root, Root outbox, subscription delta, and delivery progress atomically. + +Processor: + revalidates the derived occurrence snapshot; + opens only selected branches and semantically caused branches; + recognizes every required effective contract type; + loads only selected executable bodies and demanded data; + applies deterministic changes and internal reactions; + returns one new Root and Root's own events. +``` + +The feeder snapshot is derived execution metadata, not caller-authored Blue content and not a third semantic event field. For one managed-root revision, exact event, runtime registry, and activation state, the canonical snapshot is unique. + +### 0.4 Root-only public events + +An embedded scope may emit an event that is handled locally and observed by ancestors. It remains internal unless Root explicitly emits an event. + +```text +Emb3 emits A +Emb2 observes A and emits B +Root changes state but emits nothing + +ProcessResult.events = [] +``` + +If Root emits `C`: + +```text +ProcessResult.events = [C] +``` + +The input event is not automatically an output event. A child event is not automatically a Root event. A Document Update is not automatically a Root event. + +### 0.5 Lazy graph processing + +A verified pure reference and its materialization identify the same node: + +```yaml +x: + a: 1 + b: 1 +``` + +```yaml +x: + blueId: +``` + +The processor may open one path while siblings remain collapsed. Contract dispatch fields may be visible while executable bodies remain behind BlueId references. A patch rebuilds the changed direct node and its ancestor spine to Root. Physical prefetch is allowed, but unrelated prefetched content MUST NOT become semantic demand, contract discovery, result content, or portable gas. + +### 0.6 Core invariants + +A conforming implementation MUST preserve all of these invariants: + +1. `PROCESS` has exactly two Blue inputs: Root and external event. +2. One invocation has one authoritative Root and at most one new authoritative Root. +3. Embedded scopes are owned state inside Root, not separately committed document sessions. +4. The feeder derives one complete, revision-bound external-delivery snapshot. +5. `PROCESS` never requires a recursive scan of the complete embedded surface. +6. Inline, referenced, expanded, collapsed, warm, cold, batched, and segmented representations produce the same semantic result and portable gas. +7. Every effective contract type in the initial participating closure is recognized before the first mutation; executable bodies remain lazy. +8. Patches use persistent copy-on-write and preserve unchanged children by exact BlueId. +9. Internal Document Updates and emitted events may reach ancestors without becoming public Root output. +10. `ProcessResult.events` contains exactly Root emissions, in order and with multiplicity. +11. Checkpoints bind to channel semantic identity and are written only after complete successful delivery. +12. Gas prices deterministic logical work, not cache state, provider bytes, or unchanged transitive content. +13. Runtime semantics are selected by exact runtime-type BlueId; no document-level version field is required. +14. Deterministic failure, gas exhaustion, or transient resource suspension before commit leaves the old Root authoritative and publishes no events. +15. A successful new Root is committed only when its changed subscription surface is deterministically indexable. + +### 0.7 One external event at a glance (informative) + +The complete lifecycle of one event is: + +```text +1. The feeder closes a safe external-order window. +2. It derives the complete preselected delivery snapshot for one Root revision. +3. The processor admits the exact Root and exact event. +4. It checks direct terminated state and preflights the complete participating closure. +5. Each raw External Channel occurrence is revalidated, accepted or rejected, + checkpoint-gated, and grouped into a logical delivery. +6. Required scopes initialize from Root toward the selected descendant. +7. Selected deliveries execute deeper scopes first; selected bodies remain lazy. +8. Patches rebuild the changed identity spine, Document Updates cascade + synchronously, and emitted events drain through the internal FIFO. +9. Successful source checkpoints are written after complete delivery. +10. The final Root is validated, its subscription delta is derived, and the + platform atomically commits Root, Root events, index delta, and progress. +``` + +At no point does the processor need to materialize the complete Root graph. A host may physically prefetch more, but only demanded and causally reached content affects semantics or gas. + +### 0.8 Key terms (informative) + +| Term | Meaning | +|---|---| +| **Root** | The one authoritative Blue document state supplied to `PROCESS`. | +| **Scope** | Root or one declared embedded object occurrence participating inside that Root. | +| **Raw external occurrence** | One snapshotted External Channel at one scope path. It owns acceptance and checkpoint state. | +| **Logical delivery** | One handler execution obtained after equivalent fresh raw sources are grouped. | +| **Delivery snapshot** | Revision-bound derived evidence describing every preselected raw occurrence for the event. | +| **EventOccurrence** | Internal FIFO run state for one emitted event, its source scope, and frozen ancestor chain. | +| **Root event** | An event emitted by Root and therefore included in `ProcessResult.events`. | + +The exact external event and the derived delivery snapshot are different things. The event is immutable Blue content. The snapshot is verified execution evidence and is never inserted into the event. + +### 0.9 Reusable embedded process modules (informative) + +A reusable embedded process type defines local state, local contract roles, operations, and any nested owned processes. One occurrence becomes self-contained when it is created: every local role is bound to an exact Channel node, either materialized inline or supplied as an equivalent pure BlueId reference. + +```text +Reusable Lesson type + declares teacherChannel and studentChannel roles + +Agreement occurrence + creates one Lesson + supplies exact teacher and student Channel nodes + declares the Lesson as embedded +``` + +The same Timeline, actor, or exact Channel definition may be reused in many embedded occurrences. Reuse does not duplicate the external history and does not merge the occurrences: each concrete scope path has its own lifecycle, checkpoint state, and document state. + +Contracts 1.0 does not define implicit parent-channel inheritance. An embedded scope does not search its parent or ancestors for a contract key, and changing a parent Channel does not silently change existing child occurrences. New occurrences may be assembled using the parent's current participant configuration; existing occurrences retain their exact bindings until an explicit workflow changes or replaces them. + +Dynamic collections of process occurrences are declared through `Process Embedded.collectionPaths` (§5.2). The collection uses stable object keys; every direct member becomes one concrete embedded scope. Raw wildcard syntax and implicit list-element embedding are not part of Contracts 1.0. + +--- + +## 1. Scope, Versioning, Registry, and Conformance + +### 1.1 Goal + +Blue Contracts and Processor 1.0 defines: + +- feeder-ordered external events; +- revision-complete subscription discovery; +- branch-local processing inside one Root; +- effective inherited application contracts and direct processor state; +- immutable dispatch snapshots and lazy bodies; +- deterministic channel and handler order; +- persistent mutation to Root; +- immediate Document Update cascades; +- internal event propagation and Root-only output; +- exact checkpoint and lifecycle behavior; +- one shared gas budget and canonical counter trace; +- whole-invocation atomicity and revision-bound platform commit. + +### 1.2 Out of scope + +This specification does not define: + +- Blue Language identity or resolution algorithms; +- authentication, signatures, authorization, or mandate eligibility; +- concrete source-provider transport or cryptographic proof formats; +- database schemas, cache layouts, or provider transport; +- user-interface behavior; +- consensus among independent platforms; +- hosted pricing, billing, or service-level policy; +- the implementation of one concrete compute runtime beyond its Contracts boundary. + +Concrete external channel and executable runtime types MAY define additional deterministic semantics through exact runtime-type BlueIds. They MUST preserve this specification's one-root, representation, atomicity, output, and gas-boundary rules. + +### 1.3 Version selection + +This document defines **Blue Contracts and Processor 1.0**, the first public-version Contracts specification. + +The first public release begins at 1.0 because internal working drafts did not establish an interoperability or compatibility surface. Implementations MUST treat this specification, its canonical runtime registry, gas manifest, and fixture package as one release unit. + +A document does not carry a required `contractsVersion` or `processorVersion`. The managed execution environment selects Contracts 1.0 before processing. Concrete runtime semantics are selected by exact runtime-type BlueId and the separately published specification bound to that type. + +After a runtime-type BlueId is published, that exact BlueId MUST never acquire different semantics, dispatch fields, subscription extraction, or gas weights. + +A later incompatible change to `PROCESS`, delivery ordering, embedded-scope behavior, event propagation, checkpoints, lifecycle, atomicity, or the core gas schedule requires a new Contracts version. + +### 1.4 Runtime registry + +The canonical runtime registry is part of the Contracts 1.0 release. For every core or portable runtime type it MUST publish: + +- exact canonical Blue node and BlueId; +- runtime role; +- dispatch fields and executable-body fields; +- exact subscription functions for an External Channel; +- checkpoint-domain semantics; +- exact execution semantics or binding to another published specification; +- named runtime counters and weights when executable; +- deterministic limits and error categories; +- conformance fixtures that exercise the type. + +Registry source, calculated BlueIds, prose, fixtures, and gas manifest MUST agree. Implementations MUST NOT guess when they conflict. + +The implementation-baseline runtime registry package identity is: + +```text +sha256:46a7744c1cbfa4b00e1d8a99f6ca3f0089ef697de968fee08547894ab02b0ca1 +``` + +The machine-readable `blue-contracts/gas/1.0` manifest is normative for counter names, weights, formulas, and portable limits. Its implementation-baseline package identity is: + +```text +sha256:88c7bbe77d531c9e973cae13002c3464a2c14568833adf5d804d13b7b3d26af5 +``` + +### 1.5 Conformance + +A conforming implementation MUST: + +- implement every normative rule in this document; +- use Blue Language 1.0; +- recognize the canonical core runtime BlueIds; +- implement `PROCESS(document, event)` and the platform commit obligations; +- support all processor-managed contracts and events in Appendix A; +- support exact feeder snapshot revalidation; +- produce the canonical named gas trace required by §13 in conformance mode; +- pass every machine-readable Contracts 1.0 fixture; +- report the exact registry, gas-manifest, and fixture-package identities it implements. + +A component implementing only the processor library, feeder, node store, or a runtime may describe that component precisely, but MUST NOT claim complete Contracts 1.0 platform conformance unless the combined system satisfies all obligations. + +This specification intentionally defines a generic runtime boundary rather than one normative business channel or workflow language. The conformance harness uses identity-bound scripted runtime types to exercise that boundary. Real end-to-end applications require one or more separately published concrete External Channel and Handler/runtime specifications, each selected by exact runtime-type BlueId. + +--- + +## 2. Processing Inputs, Environment, Result, and Atomicity + +### 2.1 Processing Document + +`document` is an admitted exact Blue node. It MAY be inline, a pure reference, or partially materialized, but its exact Root BlueId MUST be established before semantic execution. The logical Root MUST be an object node. + +The Processing Document need not be a complete Resolved Form or a closed graph. Contract fields, type contributions, schemas, values, and executable bodies are expanded and resolved on demand. + +A higher-level API MAY accept Source syntax and preprocess it before `PROCESS`. That preprocessing is outside the invocation and MUST yield the same admitted Root identity on every conforming platform. + +### 2.2 Processing Event + +`event` is an admitted exact immutable Blue node. Its exact BlueId MUST be established before semantic execution. A higher-level API MAY preprocess Source-event syntax before `PROCESS`. + +The event is never rewritten to contain a target path or delivery occurrence. Exact identity, signatures, source-chain links, and checkpoint subjects therefore remain stable. + +### 2.3 Processing environment + +A managed invocation is evaluated under a fixed environment containing: + +```text +Blue Language 1.0 selection +Contracts 1.0 core gas schedule +exact runtime registry and supported runtime BlueIds +verified exact-node provider domain +managed-root session identity and current revision +revision-complete external-channel snapshot and activation intervals +canonical external-delivery plan for this Root revision and event +exact external-order policy identity +exact initial-subscription-frontier policy identity +exact poison-event/quarantine policy identity +exact Language release, Contracts release, runtime-registry, and gas-manifest identities +shared gas limit +``` + +This environment is not Blue content. It MUST be fixed for the attempt and auditably bound to the managed-root revision. + +An implementation MAY pass the canonical delivery plan to an internal processor API. The plan is a derived accelerator. It is conforming only when it equals the unique plan defined by §3. It does not change the two-input semantic operation. + +### 2.3.1 Cyclic-member processing boundary + +A final cyclic-set member identity `MASTER#index` may appear as an opaque edge inside an ordinary Root or event. It is not independently hash-verifiable and therefore MUST NOT be admitted as the top-level mutable Root or top-level event of `PROCESS`. Those inputs fail before provider demand. + +A `Process Embedded` path MUST NOT terminate at or traverse through an opaque cyclic-member edge. Structural access to an ordinary opaque member requires a cyclic-aware provider with complete set proof. Carrying an untouched opaque edge and replacing the whole edge with another admitted exact value remain valid. + +### 2.4 ProcessResult + +A completed invocation returns: + +```text +ProcessResult { + status + document + events + totalGas + diagnostic? +} +``` + +`document` is the exact resulting Root on success. Every noncommitting status returns the exact input Root. + +`events` is an out-of-band ordered sequence of exact Blue event nodes emitted by Root during the invocation. It preserves order and multiplicity. The sequence is not itself a Blue List node and has no independent BlueId inside `PROCESS`; a platform MAY wrap it in a Blue outbox envelope after processing. It is empty for every noncommitting status. + +`totalGas` is the sum of admitted canonical counters. A conformance/debug API MUST be able to expose the exact named trace; an ordinary API MAY omit it. + +`diagnostic` is deterministic, non-authoritative explanatory data. It is not part of Root or event identity. + +### 2.5 Atomic invocation + +All runtime state is tentative until the invocation completes: + +- patches and rebuilt nodes; +- processor markers and checkpoints; +- internal queues; +- runtime outputs; +- Root events; +- subscription-delta validation; +- gas trace. + +A committing `success` returns the tentative Root and Root events. Every deterministic failure or gas exhaustion discards all tentative state and events and returns the input Root. + +Transient acquisition failure does not produce a completed `ProcessResult`; the host suspends the attempt and retries from the exact input Root and event with more verified evidence. + +### 2.6 Representation invariance + +For graph-equivalent Root and event inputs under the same environment, a conforming implementation MUST return: + +- the same status and diagnostic category; +- the same resulting Root BlueId; +- the same ordered Root event identities; +- the same exact counter trace and total gas; +- the same semantic provider demands. + +Physical fetch count, cache hits, allocation, node batching, and serialized bytes are not portable outputs. + +### 2.7 Platform commit + +A committing result is installed only through compare-and-swap against the exact Root BlueId and revision from which it was calculated. + +The platform transaction MUST atomically persist: + +```text +new Root and new revision +Root outbox = ProcessResult.events +validated incremental subscription-index delta +subscription activation and retirement intervals +delivery progress for the external event +``` + +For a nonmutating terminal result, the platform MUST compare-and-swap delivery progress against the exact unchanged Root BlueId and revision. This prevents a `no-match`, `stale`, or failure decision calculated on an old Root from suppressing an event that a newer Root would handle. + +A compare-and-swap conflict commits nothing. It is host contention, not portable Contracts gas; the event is re-derived from the new authoritative revision. + +--- + +## 3. Managing Feeder, Subscriptions, and External Order + +### 3.1 Feeder responsibility + +The managing feeder MUST: + +- derive the active external subscription surface from Root and transitively declared embedded scopes; +- maintain that surface incrementally for each committed Root revision; +- observe every active source identified by that surface; +- obtain the completeness evidence required by each concrete external-source specification; +- select the chronologically next eligible external event; +- derive and retain the canonical delivery snapshot; +- ensure one event reaches a terminal progress record before a later external event begins; +- keep the subscription index at the authoritative Root revision. + +The initial admission of a managed Root MAY inspect its complete declared subscription surface once. Later revisions MUST be updated from changed branches and effective dependencies; a complete recursive scan before every event is nonconforming to the locality objective. + +### 3.2 External-channel snapshot + +For every active External Channel occurrence, the feeder stores a deterministic snapshot: + +```text +ExternalChannelSnapshot { + scopePath + channelKey + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + order + dispatchHeader + subscriptionKeys + checkpointDomainBlueId + declaredSameScopeChannelDependencies + sameScopeChannelCatalogIdentity? +} +``` + +The snapshot is derived from the effective channel contract at one Root revision. It does not require an invented BlueId for a merged effective contract. `orderedSourceContributionNodeBlueIds` records exact ancestor-to-descendant contributions. + +The dispatch header contains only the bounded immutable fields registered by that channel type. Executable body fields are not part of the subscription snapshot. + +### 3.3 Required external-channel functions + +Each portable External Channel runtime type MUST define exact deterministic functions: + +```text +CHANNEL_KEYS(snapshot) -> finite ordered set of subscription keys +EVENT_KEYS(event) -> finite ordered set of event keys +PRESELECTS(snapshot, event) -> Boolean +ACCEPTS(snapshot, event, context) -> Boolean +PAYLOAD(snapshot, event, context) -> exact channelized Blue node, when accepted +CHECKPOINT_DOMAIN(snapshot, context) -> exact BlueId +CHECKPOINT_SUBJECT(snapshot, event, payload, context) -> exact node identity +DECLARE_CHANNEL_DEPENDENCIES(snapshot, context) -> exact keys or bounded whole-catalog declaration +HANDLER_CHANNEL_KEY(snapshot, event, payload, context) -> same-scope Channel key +LOGICAL_DELIVERY_KEY(snapshot, event, payload, context) -> deterministic Text +``` + +The following laws are normative: + +1. `ACCEPTS(snapshot, event) => PRESELECTS(snapshot, event)`. +2. `PRESELECTS(snapshot, event) => intersection(CHANNEL_KEYS(snapshot), EVENT_KEYS(event)) is non-empty`. +3. `PRESELECTS`, `ACCEPTS`, and `PAYLOAD` depend only on the immutable snapshot, exact event, registered deterministic semantics, and explicitly demanded event content. +4. They MUST NOT depend on mutable Root fields, initialization effects, cache state, wall-clock time, or ambient I/O. +5. Business-state conditions belong in Handler predicates or workflow logic, not External Channel acceptance. +6. The functions are representation-blind and bounded by the portable limits. + +A channel that cannot provide finite subscription keys is not a portable External Channel under Contracts 1.0. + +#### 3.3.1 Same-scope Channel dependencies + +An External Channel may need immutable headers from another same-scope Channel in order to classify an accepted event. This is a generic Contracts capability; it does not imply that the peer Channel is an external source for the event. + +During subscription/header evaluation the runtime MUST declare either: + +```text +one or more exact same-scope Channel keys +or +one bounded complete same-scope Channel catalog +``` + +The retained subscription interval records the declared dependency surface and its exact identity. The complete catalog contains the canonical raw-key membership of the effective `contracts` map and read-only header snapshots for every effective same-scope Contract whose runtime role is External Channel or Processor Channel. It does not include executable bodies. + +During event classification the runtime receives a read-only context with exact lookup: + +```text +LOOKUP_CHANNEL(rawKey) -> CHANNEL(snapshot) | ABSENT | NON_CHANNEL +``` + +`ABSENT` is valid only when a declared complete catalog establishes that the raw key is semantically absent. `NON_CHANNEL` establishes that an effective Contract exists at the raw key but its runtime role is not a Channel. A lookup outside the declared dependency surface, unavailable evidence, changed contribution identity, or incomplete catalog MUST fail closed; it MUST NOT be converted to `ABSENT`. + +A `ChannelMemberSnapshot` contains only: + +```text +raw key +order +effective type BlueId +runtime role +ordered source-contribution BlueIds +registered immutable dispatch/header fields +deterministic dependency BlueIds +header identity +``` + +Reading a peer snapshot MUST NOT evaluate that peer as an External Channel, give it checkpoint authority, run its handlers, or load an executable body. + +#### 3.3.2 Source Channel and handler Channel + +Every accepted raw External Channel occurrence has two channel identities: + +```text +sourceChannelKey +handlerChannelKey +``` + +The source Channel performed external acceptance and owns checkpoint domain, checkpoint subject, and checkpoint write. `HANDLER_CHANNEL_KEY` defaults to the source key but MAY select another declared same-scope Channel key. The selected target MUST resolve to a `CHANNEL` lookup result. A concrete runtime MAY define ordinary-source fallback for `ABSENT` or `NON_CHANNEL`; the fallback rule is part of that exact runtime type and MUST be deterministic. + +The target Channel is not evaluated as another external occurrence and is not checkpointed merely because it is the handler target. Handlers are selected by the frozen `handlerChannelKey`. + +Informative example: + +```text +sourceChannel accepts an externally attributed message +message payload names operationsChannel as the effective target +handlers bound to operationsChannel execute +sourceChannel owns the checkpoint +operationsChannel is not separately accepted or checkpointed +``` + +This supports delegated or routed operation protocols without rewriting the external event or adding a third `PROCESS` input. + +#### 3.3.3 Logical delivery grouping + +After rejection and stale filtering, accepted-new raw source occurrences are grouped by: + +```text +(scopePath, logicalDeliveryKey) +``` + +The default `logicalDeliveryKey` is the raw source key. Every source in one group MUST agree on: + +```text +exact payload identity +handlerChannelKey +logical delivery identity +``` + +One group executes the target handlers exactly once. Every fresh participating source retains its own checkpoint domain and subject. All participating source checkpoints commit only after the grouped handler execution and caused internal-event drain succeed. Failure, termination before checkpoint, cut-off, gas exhaustion, or rollback commits none of the group's source checkpoints. Rejected and stale sources are not participants. + +If fresh sources assigned to one group disagree on payload identity, handler Channel identity, or logical delivery identity, classification fails atomically with `runtime-fatal` and diagnostic category `InconsistentLogicalDelivery`. No initialization, Handler execution, checkpoint, Root event, or document mutation commits. + +Logical grouping is run state, not Blue content and not part of `ProcessResult`. + +### 3.4 Revision-complete subscription index + +Before the feeder selects an event: + +```text +subscriptionIndex.indexedRootRevision == managedRoot.revision +subscriptionIndex.indexedRootBlueId == managedRoot.currentRootBlueId +``` + +MUST hold. + +The index MAY physically over-approximate and return false positives. Before canonical delivery ordering and portable occurrence limits are applied, raw candidates MUST be filtered by exact `PRESELECTS` using the current channel snapshot and event. + +The index MUST NOT omit an active snapshot for which `PRESELECTS` is true. Omission is infrastructure nonconformance, not `no-match`. + +A direct terminated marker prunes that scope and all declared descendants from later subscription snapshots. + +### 3.5 Subscription activation intervals + +Feeder state MUST record when one channel occurrence begins and ends observing external order: + +```text +SubscriptionInterval { + scopePath + channelKey + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + activationRootRevision + startAfterExternalOrderKey + endAtRootRevision? +} +``` + +For initial Root admission, platform policy MUST explicitly choose one frontier per external source: + +```text +full history +from a declared order key +from the admission order key +``` + +A channel or embedded scope introduced while processing event `E` begins strictly after `E`'s canonical external-order key. It never joins `E`. + +Removing and later re-adding a channel starts a new interval unless the exact channel runtime type explicitly defines a deterministic checkpoint/cursor migration. Reusing the same contract key does not silently resume a semantically different channel. + +### 3.6 External completeness and canonical order + +The feeder MUST not process event `E` until the concrete external-source ecosystem has supplied completeness evidence that no active subscribed source can later produce an eligible event ordered before `E`. + +Each concrete external-source specification MUST publish: + +```text +source-local order key +source-local completeness rule +stable source identity used by the external-order policy +``` + +The managed execution environment binds one exact **external-order policy identity**. That policy MUST define a strict total order over eligible events from all active sources and satisfy all of these laws: + +1. **Per-source consistency.** If one source's final order places `A` before `B`, the cross-source policy MUST also place `A` before `B`. +2. **Totality.** For any two distinct eligible event occurrences, exactly one orders before the other. +3. **Determinism.** The result depends only on identity-bound source evidence and policy fields, never arrival order, query order, cache state, locale, or host scheduling. +4. **Stable tie-breaking.** Equal source-neutral time values or other primary keys are resolved by exact identity-bound tie-break fields published by the policy. +5. **Policy stability.** The policy identity is fixed for the managed-root session or changed only through an explicit migration that defines progress continuity. +6. **Completeness compatibility.** Before selecting `E`, the feeder has evidence from every active source interval that no still-eligible event can later appear with a global order key less than `E`. + +Contracts core treats concrete order-key components as opaque evidence. It does not define clocks, timelines, providers, or one universal tie-break tuple. + +An informative feeder loop is: + +```text +repeat: + assert subscription index matches authoritative Root revision + obtain each active source's next known event and completeness frontier + choose the least globally ordered candidate E + wait until every active source proves no eligible event precedes E + derive the complete preselected delivery snapshot for E + process and persist one revision-bound terminal result for E +``` + +No later external event may interleave with the retained deliveries of the current event. The complete canonical delivery set of `E` reaches one terminal progress record before the feeder begins `E2`. + +### 3.7 Canonical delivery snapshot + +For Root revision `R` and event `E`, the feeder selects every active interval whose snapshot satisfies `PRESELECTS(snapshot, E)`. + +It records: + +```text +ExternalDelivery { + scopePath + channelKey + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + order + checkpointDomainBlueId +} +``` + +Canonical order is: + +1. greater `scopePath` depth first; +2. normalized `scopePath` by Unicode code-point order; +3. effective channel `order`, ascending; +4. raw `channelKey`, Unicode code-point order; +5. effective type BlueId as a final deterministic tie-breaker. + +The snapshot is retained across retries against the same Root revision. A new Root revision requires a new snapshot. + +### 3.8 Revalidation and false positives + +The processor revalidates every delivery before use: + +- each path segment remains declared by the snapshotted Process Embedded contribution; +- the scope exists as an object and is not under a direct terminated scope; +- the same effective channel contribution identity remains at the same key; +- the channel type and checkpoint domain match the snapshot; +- `PRESELECTS` and `ACCEPTS` are re-evaluated against the exact event. + +A stale physical index false positive therefore becomes a deterministic skipped or rejected occurrence. An omitted true occurrence is not harmless and is feeder failure. + +### 3.9 Terminal delivery progress and poison events + +Every terminal outcome is persisted against the exact Root revision: + +```text +success +no-match +stale +terminated +capability-failure +invalid-processing-document +runtime-fatal +gas-limit-exceeded +portable-limit-exceeded +subscription-surface-invalid +``` + +A completed event is not automatically resubmitted against the same revision. Repeated deterministic failure or gas exhaustion MUST be quarantined or explicitly administratively retried; it MUST NOT block the external-order queue forever through unbounded automatic retry. + +--- + +## 4. Contracts, Runtime Types, and Discovery + +### 4.1 `contracts` map + +Every scope MAY contain an effective `contracts` object: + +```yaml +contracts: + : +``` + +Contract entries are ordinary identity-bearing Blue content. Application contracts are obtained from the effective Language-resolved contracts map. Processor state at reserved keys is always direct state and is never inherited. + +### 4.2 Contract-map key grammar + +A contract key MUST: + +- be non-empty Text; +- be a legal ordinary Blue child key; +- not equal a Language reserved or reserved-invalid key; +- contain at most 256 Unicode code points and 1,024 UTF-8 bytes; +- be representable as one escaped Runtime Pointer segment. + +`/` and `~` are allowed in the raw key and are escaped only for pointers. + +### 4.3 Runtime roles + +Every effective Contract subtype has one registered runtime role: + +| Role | Meaning | +|---|---| +| External Channel | Entry point for the external `PROCESS` event. | +| Processor Channel | Entry point for Document Update, Triggered, Lifecycle, or Embedded delivery. | +| Handler | Deterministic logic bound to one same-scope channel key. | +| Marker | Runtime state or policy; does not execute as a handler. | +| Executable extension | A registered additional role with exact semantics. | + +A Contract subtype with an unsupported role or exact type is not inert. It is subject to must-understand failure. + +### 4.4 Effective contract snapshot + +For every effective contract key demanded by processing, the processor constructs an immutable out-of-band snapshot: + +```text +EffectiveContractSnapshot { + scopePath + key + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + role + order + resolvedDispatchFields + executableBodyNodeBlueIds + deterministicDependencyNodeBlueIds +} +``` + +The snapshot records exact contributions rather than manufacturing a synthetic merged-contract BlueId. + +The runtime implementation for `effectiveTypeBlueId` defines which fields it demands at each stage. The generic processor MUST resolve the type of every effective contract in a participating scope, but MUST NOT load an executable body merely to classify or reject the entry. + +### 4.5 Direct processor state first + +Before enumerating application contracts in a scope, the processor reads and validates direct reserved state: + +```text +contracts/terminated +contracts/initialized +contracts/checkpoint +``` + +A valid direct terminated marker makes the scope inactive. Unsupported application contracts inside that inactive scope are not recognized for the current invocation. + +A type-derived initialized, terminated, or checkpoint marker has no runtime effect. + +### 4.6 Must-understand preflight + +Before the first mutation, the processor MUST preflight the complete **initial participating closure**: + +- every preselected delivery scope that still exists; +- every declared ancestor from Root to those scopes; +- every effective contract type in those scopes; +- direct processor marker shapes; +- Process Embedded path structure; +- handler/channel binding structure; +- portable limits required before execution. + +Preflight recognizes types and dispatch fields but not unselected executable bodies. + +If an unsupported type, role, or required dispatch rule is found, the invocation returns `capability-failure`, input Root, no events, and admitted gas. + +A patch or generated write affecting `/contracts`, `/type`, a type contribution, or another effective-contract dependency MUST repeat must-understand validation for the changed effective closure before processing continues or commit occurs. + +### 4.7 Deterministic ordering + +Channels and handlers are ordered by: + +1. effective `order`, ascending; absent means `0`; +2. raw contract key, Unicode code-point order. + +The canonical candidate list begins in contract-key order and is sorted by the stable merge-sort accounting rule in §13.10. Implementations MAY use indexes, but the logical order and trace are fixed. + +### 4.8 Dispatch snapshots + +For one channel delivery, the handler candidate list is snapshotted immediately before the first handler predicate is tested. The snapshot freezes key, contribution identities, effective type, dispatch fields, order, and body identities. + +Changes to contracts during that delivery do not add, remove, reorder, or replace candidates in the current snapshot. They affect later discovery points. + +For an accepted external delivery, its channel snapshot, payload, checkpoint domain, and checkpoint subject are frozen before initialization. Initialization may change the current contracts map, but the already accepted delivery continues from its frozen snapshot unless its scope is cut off or terminated. Handler discovery occurs after initialization and therefore observes post-initialization contracts. + +### 4.9 Same-scope binding + +A Handler binds to exactly one channel key in the same scope through its effective `channel` field. A missing same-scope channel makes the Handler inert unless its exact runtime type declares that shape invalid. + +The effective contracts of an embedded scope are resolved from that scope's own content, type chain, and overlays. Embedding does not import, inherit, or alias contracts from a parent or ancestor scope. A contract key in an ancestor has no same-scope effect in the child merely because the raw key is equal. + +An exact Channel node may be reused in several scopes. These are representation-equivalent bindings: + +```yaml +teacherChannel: + blueId: +``` + +```yaml +teacherChannel: + type: + # exact materialized content whose BlueId is ExactChannelBlueId +``` + +The two forms identify the same Channel value. They do not create a live link to another contract-map key. If a parent later replaces its own Channel, an existing child reference still identifies the old exact Channel until the child occurrence is explicitly changed. + +Contracts 1.0 defines no informal `Parent Channel`, ancestor-key lookup, nearest-parent lookup, or context-dependent channel port. A future runtime may define an explicit cross-scope binding type only through a separately published exact runtime-type BlueId and complete dependency, subscription, checkpoint, invalidation, cycle, and gas semantics. Implementations MUST NOT infer such behavior from ordinary embedding or raw key equality. + +A child event reaches an ancestor only through an Embedded Node Channel. A descendant field change reaches an ancestor through a Document Update Channel. + +### 4.10 Effective protected state + +The following state is processor-protected: + +```text +direct initialized marker identity +direct terminated marker identity +direct checkpoint marker identity +effective Process Embedded type and every non-path field +effective Type Generalization Policy +``` + +For every application patch and generated type write: + +```text +EFFECTIVE_PROTECTED_STATE(before) + == +EFFECTIVE_PROTECTED_STATE(after) +``` + +MUST hold, except that an explicitly permitted patch to the declaration fields `contracts/embedded/paths` or `contracts/embedded/collectionPaths` may change only those declaration fields while preserving the exact Process Embedded type and every other effective field. + +This comparison catches indirect changes caused by replacing `/type`, `/contracts`, or an ancestor of a protected contribution. + +### 4.11 Execution context + +A runtime call may receive only deterministic values: + +```text +$scope current scope path +$document read-only view of current Root +$event current channelized payload +$processingEvent original external PROCESS event +$contract frozen current contract snapshot +$channel frozen channel snapshot, when applicable +$gas shared live-bounded meter +``` + +The context MUST NOT expose wall-clock time, randomness, ambient I/O, host object identity, mutable caches, thread scheduling, or unregistered state. + +### 4.12 ContractExecutionResult + +A Handler or executable Channel returns: + +```text +ContractExecutionResult { + patches ordered list, default [] + events ordered list, default [] + termination optional + runtimeLedger optional only when not debiting the shared meter directly +} +``` + +Application order is: + +1. validate and merge the runtime ledger exactly once; +2. apply patches in list order, each with its complete synchronous Document Update cascade; +3. record emitted events in list order; +4. apply the first termination request. + +An invalid result shape fails before any effect from that result is applied. Whole-invocation atomicity still discards earlier tentative effects. + +### 4.13 Runtime body demand and meter + +A candidate body is demanded only after its matcher succeeds. Passing an already admitted exact node into or out of a runtime preserves its BlueId and MUST NOT recursively clone, serialize, or size it. + +A runtime either debits the shared meter live or uses a child meter initialized with the exact remaining budget. It MUST NOT do both for the same work. A child ledger is validated and merged exactly once. + +--- + +## 5. Root and Embedded Scopes + +### 5.1 Scope + +A **scope** is an object node inside Root that owns an effective contracts map and is either: + +- Root at `/`; or +- a path declared by the nearest ancestor's effective Process Embedded contract. + +The root scope always exists. A declared embedded scope exists only while its path contains an object node. + +### 5.2 Process Embedded + +The reserved key `contracts/embedded` contains a Process Embedded marker. It has two explicit declaration forms: + +```yaml +contracts: + embedded: + type: Process Embedded + + paths: + - /payment + - /delivery + + collectionPaths: + - /lessons + - /refunds +``` + +`paths` contains exact Runtime Pointers. Each path identifies one immediate owned embedded scope root. + +`collectionPaths` contains exact Runtime Pointers to object-compatible collection nodes. Every direct ordinary member present under such a collection becomes one immediate owned embedded scope root at the concrete path: + +```text +collection path: /lessons +member key: lesson-17 +concrete scope: /lessons/lesson-17 +``` + +The collection container itself is not an embedded scope unless it is separately declared by a different valid ancestor marker. One Process Embedded marker MUST contain at least one non-empty `paths` or `collectionPaths` list after effective resolution. + +Process Embedded defines: + +1. owned child contract scopes; +2. mutation boundaries; +3. the recursive feeder subscription surface. + +It does not broadcast the current external event to every child. It does not import parent contracts into a child. It never turns a contract entry under `/contracts` into a scope. + +### 5.3 Embedded declaration validity + +Every entry in `paths` and `collectionPaths` MUST: + +- be a normalized Runtime Pointer beginning with `/`; +- not equal `/`; +- use object-member segments only; +- not traverse list positions; +- not contain wildcard, glob, selector, or query syntax; +- not pass through `contracts`, `type`, `schema`, `items`, or another Language-reserved field; +- be unique within its declaration list; +- not overlap another immediate declaration by ancestor/descendant relation. + +A `paths` entry may be absent from the current document and then contributes no active scope. When present, it MUST resolve to an object node or a verified pure reference to an object node. + +A `collectionPaths` entry may be absent and then contributes no active scopes. When present, it MUST resolve to an object-compatible node. Lists are not collection targets under Contracts 1.0. Every direct ordinary member under the collection MUST be an object node or a verified pure reference to an object node. A present scalar, list, cyclic-member boundary, or otherwise non-object member makes the subscription surface invalid. + +For one collection, direct member keys are ordered by Unicode code-point order. Each key is escaped as one Runtime Pointer segment to derive its concrete scope path. The processor and feeder MUST use the concrete paths, not a wildcard expression, in delivery snapshots, activation intervals, checkpoints, propagation chains, and diagnostics. + +The combined concrete child set from `paths` and `collectionPaths` MUST be duplicate-free. It is invalid when: + +- an explicit `paths` entry equals a collection-generated member path; +- one declaration is a strict ancestor or descendant of another immediate declaration; +- the same collection is declared twice through graph-equivalent pointers; +- two declarations generate the same concrete path. + +Traversal MUST reject an embedded ancestry cycle, including revisiting the same exact node on the current declared ancestor chain. + +### 5.4 Entry snapshot and collection membership + +When a scope first participates, the processor freezes: + +```text +ENTRY_EXPLICIT_EMBEDDED_PATHS(scope) +ENTRY_EMBEDDED_COLLECTION_PATHS(scope) +ENTRY_COLLECTION_MEMBER_KEYS(scope, collectionPath) +ENTRY_EMBEDDED_PATHS(scope) # exact combined concrete child paths +ENTRY_SCOPE_ROOT_IDENTITY(scope) +ENTRY_ANCESTOR_CHAIN(scope) +``` + +For each collection path, `ENTRY_COLLECTION_MEMBER_KEYS` is the complete direct key set in Unicode code-point order. `ENTRY_EMBEDDED_PATHS` is produced by combining exact `paths` entries with every concrete collection-member path and then applying canonical Runtime Pointer ordering. + +The frozen concrete path set is used for current-event path verification, mutation boundaries, delivery ordering, cut-off, and propagation. Changes to `paths`, `collectionPaths`, collection membership, or direct collection keys affect later external events only. + +A member added while processing event `E` is ordinary tentative Root content during `E`; it is not a participating scope for `E`. After commit it begins a new subscription interval strictly after `E`'s external-order key. A removed member retires its occurrence at the committed revision. Removing and later re-adding the same key creates a fresh occurrence interval and does not reuse the prior occurrence's checkpoint state unless an exact runtime type defines an explicit deterministic migration. + +The entry root identity identifies the active occurrence for cut-off detection. Ordinary persistent writes strictly inside the occurrence create new node identities but preserve the occurrence. A whole-occurrence replacement by an ancestor with a different exact node ends it. + +### 5.5 Participating closure + +A scope participates when it: + +- has an accepted new external delivery; +- is an ancestor required to initialize or observe such a delivery; +- receives a Document Update; +- receives an internal emitted event; +- receives a lifecycle event. + +The initial closure is known from the external delivery snapshot and its ancestors. Additional internal participation is recognized at the first caused delivery. + +Sibling and unrelated embedded branches remain inactive and MUST NOT be semantically expanded or discovered. + +### 5.6 One authoritative Root + +An embedded scope has no separate committed current-state record. Its current state is the exact node reachable from the authoritative Root. + +An implementation MAY store tentative intermediate nodes by BlueId. Storage does not make them current state. Only the final Root compare-and-swap does. + +### 5.7 Mutation boundaries + +Let `S` be the executing scope and `E(S)` its immediate child roots from the exact combined `ENTRY_EMBEDDED_PATHS(S)`, including collection-generated concrete member paths. + +An application patch from `S` MAY: + +- change a strict descendant of `S` that is not strictly inside any child root in `E(S)`; +- add, replace, or remove one immediate child root in `E(S)` as a whole; +- add a new direct member under an entry-snapshotted `collectionPaths` container, provided the final value is an object-compatible node and the resulting subscription surface is valid. + +A newly added collection member is not added to `E(S)` for the current event. It becomes an embedded occurrence only after the new Root commits and the next revision's subscription surface is derived. + +It MUST NOT: + +- patch document Root `/`; +- replace or remove its own scope root; +- patch strictly inside an immediate child root; +- patch a strict ancestor of an immediate child root; +- replace or remove a collection container as a whole while it contains entry-snapshotted active child roots; +- cross into a cyclic-set member. + +The strict-ancestor rule is intentionally simple. Authors must use an exact child-root operation rather than an ambiguous ancestor replacement. + +### 5.8 Active-scope cut-off + +When an ancestor removes an active embedded scope root or replaces it with a different exact node: + +- that active occurrence and all active descendants are marked cut off; +- pending external deliveries at those paths are skipped; +- no new local handler begins there; +- unapplied patches, events, and termination requests from its current buffered result are discarded; +- no initialization, checkpoint, or termination marker is written into the replacement; +- a currently executing call may return, but the processor checks cut-off before applying each remaining buffered effect; +- events already emitted before cut-off continue along the ancestor chain frozen at emission; +- the Document Update that caused cut-off continues along its frozen receiving chain; +- re-adding the same path does not resurrect the old occurrence during this invocation. + +Replacing a child root with the exact same current BlueId is a semantic no-op and does not cut off the occurrence. + +The processor MUST check cut-off after every nested cascade and before every marker or checkpoint write. + +### 5.9 Frozen propagation chains + +Every emitted event and every Document Update freezes its source scope and active ancestor chain when the occurrence is created. Later changes to Process Embedded declarations do not redirect an already-created occurrence. A removed or terminated receiving ancestor may stop its own local reaction, but an event that already happened is not silently rewritten to have a different source. + +### 5.10 Participant bindings in reusable process occurrences (normative boundary; informative pattern) + +A reusable process type may declare local Channel roles such as `teacherChannel`, `studentChannel`, `buyerChannel`, or `sellerChannel`. Each concrete occurrence supplies exact Channel values for those local keys. The values may be inline or equivalent pure BlueId references. + +The process occurrence is self-contained after creation. Its current subscription surface and authority are functions of its own exact content and registered runtime semantics, not of the unrelated current content of its parent. + +Recommended application behavior is: + +```text +new process occurrence: + instantiate using the enclosing document's current participant configuration + +existing process occurrence: + retain its exact bindings + +participant change inside one occurrence: + perform an explicit authorized workflow that replaces local Channel values + +agreement-wide migration: + explicitly update or replace the selected existing occurrences +``` + +For a Channel-changing event, the pre-change frozen source snapshot authorizes and checkpoints the current delivery. The new Channel surface becomes active only after the Root transition commits. Thus an old participant set may validly govern the transition to a new participant set, while later events use the new set. + +Changing a parent Channel does not silently rewrite a child's exact binding. Contracts 1.0 intentionally chooses explicit participant snapshots over context-dependent live parent lookup. + +### 5.11 Addressing dynamic collection members (normative boundary; informative example) + +`collectionPaths` declares which object members are active embedded scopes. It does not define how an external protocol addresses one member. Addressing is part of the concrete External Channel runtime through `CHANNEL_KEYS`, `EVENT_KEYS`, `PRESELECTS`, and `ACCEPTS` (§3.3). + +A concrete channel may use a stable document-routing identity in the event and scope header. For example, a Timeline Entry protocol may derive keys from: + +```text +documentId + timeline identity + actor identity +``` + +This allows many embedded process occurrences to reuse one physical Timeline while the feeder selects only the occurrence named by the event's `documentId`. Another channel type may use a different finite target projection. + +A stable logical document identifier and a BlueId serve different purposes: + +```text +stable document-routing identity: + identifies the continuing process occurrence for the external protocol + +BlueId: + identifies one exact immutable state of that occurrence +``` + +Contracts core does not mandate a field named `documentId`; it requires each portable External Channel type to publish finite, deterministic subscription and event keys. If a channel's keys do not distinguish several occurrences sharing one source, all matching occurrences may be preselected and normal canonical delivery rules apply. + +--- + +## 6. Events and Processor-Managed Channels + +### 6.1 Event model + +Events are immutable Blue nodes. The processor distinguishes: + +- the one external `PROCESS` event; +- lifecycle events; +- Document Update payloads; +- application events emitted by handlers; +- Embedded Event Delivery wrappers used for ancestor observation. + +Only application or lifecycle events emitted by Root are included in `ProcessResult.events`. + +### 6.2 External Channel + +An External Channel is evaluated only for an occurrence in the canonical feeder snapshot. + +For one occurrence, the processor: + +1. revalidates its path and channel snapshot; +2. evaluates `PRESELECTS` and `ACCEPTS` against the exact event; +3. constructs and freezes the channelized payload; +4. calculates and freezes checkpoint domain and subject; +5. evaluates checkpoint newness; +6. if new, initializes the required scope chain and invokes matching handlers. + +External Channel acceptance is immutable for this event and cannot read mutable Root business state. A Channel may accept while no Handler matches; the accepted new occurrence is still checkpointed. + +### 6.3 Document Update + +Every successful application patch or generated type-generalization write creates one immutable **update occurrence** in run state. The occurrence freezes: + +```text +absolute changed path from Root +absolute patch-origin scope path +before/after exact snapshots and presence +frozen receiving ancestor chain +semantic update operation +``` + +The underlying occurrence is created once. For each receiving scope, the processor deterministically renders one scope-relative Document Update payload: + +```yaml +type: Document Update +op: add | replace | remove +path: +beforePresent: true | false +before: +afterPresent: true | false +after: +sourceScopePath: +``` + +The payload may therefore contain different relative `path` and `sourceScopePath` values at different receiving scopes while representing the same immutable underlying occurrence. + +`before` and `after` are omitted when the corresponding presence Boolean is false. Null is not used as an absence sentinel. + +The semantic `op` is determined from presence, not merely copied from the authored Json Patch Entry: + +```text +before absent, after present -> add +before present, after present -> replace +before present, after absent -> remove +same exact before/after BlueId -> no Document Update +``` + +Therefore an authored object-member `replace` used as an upsert produces `op: add` when the member was absent. + +A Document Update Channel declares a scope-relative watched `path`. It matches when the changed path is equal to or below the watched path. + +### 6.4 Immediate Document Update cascade + +After one patch has been persistently applied and type soundness restored, its Document Update is delivered synchronously: + +```text +origin scope +nearest active ancestor +... +Root +``` + +At each receiving scope: + +1. discover and snapshot current matching Document Update Channels and Handlers; +2. process them in `(order, key)` order; +3. completely apply every matching Handler result before moving to the next receiving scope. + +The cascade does not wait for the application-event queue. A nested patch creates and completely processes its own cascade before the enclosing Handler result continues. + +The receiving chain is frozen when the update occurs. A handler may cause active-scope cut-off under §5.8; the current update still continues to higher receiving ancestors, but no later buffered effect from the cut-off source is applied. + +### 6.5 Application event emission + +When a Handler emits an event, the processor: + +1. validates the event as an admissible exact Blue node; +2. retains or establishes its exact identity; +3. records an internal EventOccurrence with the source scope and frozen ancestor chain; +4. appends the event to `ProcessResult.events` immediately if and only if the source scope is Root; +5. appends the occurrence to the invocation FIFO. + +The FIFO record is run state, not Blue content. It has no BlueId and is never returned. + +### 6.6 Triggered Event Channel + +When an EventOccurrence is dequeued, it is first delivered to matching Triggered Event Channels in its source scope, provided that source occurrence remains active, nonterminating, and nonterminated. + +Every delivery uses fresh channel and Handler snapshots. Events emitted by those handlers are appended to the FIFO after the currently dequeued occurrence. + +### 6.7 Embedded Node Channel + +After local Triggered handling, the same occurrence is offered to each active receiving ancestor in nearest-first order through Embedded Node Channels. + +The processor provides an exact channelized wrapper conceptually equivalent to: + +```yaml +type: Embedded Event Delivery +sourcePath: +event: + blueId: +``` + +The nested event is retained by exact identity. A receiving ancestor's Handler may explicitly emit the nested event or another event. Observation alone does not make it an event emitted by that ancestor. + +### 6.8 Lifecycle Event Channel + +The processor emits these lifecycle events: + +```text +Document Processing Initiated +Document Processing Terminated +``` + +Lifecycle Channels receive only processor-generated lifecycle events. Lifecycle handlers follow the same snapshot, result, queue, cut-off, and gas rules as other handlers. + +A deterministic failure or gas exhaustion rolls back lifecycle events with every other tentative effect. Fatal errors are returned as diagnostics; they are not separately emitted as committed application events. + +### 6.9 Event queue order + +The canonical queue order is FIFO by emission occurrence. For one occurrence: + +```text +source Triggered delivery +then nearest ancestor Embedded delivery +then next ancestor +... +then Root +``` + +Every caused patch and its full Document Update cascade completes synchronously before that event delivery continues. Events emitted during one delivery are appended to the FIFO and do not interrupt the current occurrence. + +The queue is drained in exactly one place: `DRAIN_INTERNAL_EVENTS` in §7.8. External-delivery helpers and lifecycle helpers enqueue events but MUST NOT independently drain the same queue. + +### 6.10 Processor-managed writes + +Processor-managed writes are classified as follows: + +| Write | Creates Document Update? | +|---|---:| +| Application Json Patch | Yes | +| Generated type-generalization write | Yes | +| Whole embedded child-root application patch | Yes | +| Processing Initialized Marker | No | +| External channel checkpoint | No | +| Processing Terminated Marker | No | + +Processor marker writes still pay pointer, identity, validation, and fixed processor gas. Lifecycle Channels are the observation mechanism for initialization and termination. + +--- + +## 7. Normative Processing Algorithm + +### 7.1 Run state + +One invocation maintains tentative state conceptually equivalent to: + +```text +RUN.inputRootBlueId +RUN.processingEvent +RUN.deliverySnapshot +RUN.acceptedNewDeliveries +RUN.acceptedStaleDeliveries +RUN.entryEmbeddedPaths +RUN.entryScopeRootIdentities +RUN.initializedScopes +RUN.activeScopes +RUN.cutOffScopes +RUN.terminatingScopes +RUN.terminatedScopes +RUN.eventQueue +RUN.rootEvents +RUN.contractSnapshots +RUN.validationProofs +RUN.openedNodeManifests +RUN.gasTrace +``` + +Implementation structures may differ. Observable result and canonical trace may not. + +### 7.2 Phase A — admission and direct Root state + +```text +1. Require admitted exact Root and event identities. +2. Require Root to be an object. +3. Begin the shared gas meter and charge processInvocation. +4. Read the direct Root terminated marker before application contracts. +5. If Root is already terminated, return status terminated, input Root, [], admitted gas. +6. Require the feeder snapshot to be bound to this exact Root revision and event. +``` + +Invalid provider content or unavailable required nodes are handled before or through the acquisition boundary in §12.4. + +### 7.3 Phase B — revalidate and classify external deliveries + +For each snapshot entry in canonical order: + +1. verify only the declared branch from Root to target; +2. freeze entry scope/path state as needed; +3. skip a path already cut off or under a direct terminated scope; +4. resolve the exact effective channel contribution snapshot; +5. skip when the snapshot no longer exists unchanged; +6. charge and evaluate `PRESELECTS` and `ACCEPTS`; +7. if rejected, record no accepted delivery and continue; +8. construct and freeze payload, checkpoint domain, and subject; +9. evaluate declared same-scope Channel dependencies; +10. freeze `handlerChannelKey` and `logicalDeliveryKey`; +11. compare the source checkpoint; +12. record the accepted raw source occurrence as `new` or `stale`; +13. after all entries are classified, group accepted-new sources under §3.3.3 and reject inconsistent groups before mutation. + +This phase is read-only. It does not initialize, execute Handlers, write checkpoints, or mutate Root. + +Because acceptance cannot depend on mutable Root state, classification is stable for the invocation. A later scope cut-off may still invalidate a previously classified occurrence. + +### 7.4 Phase C — must-understand preflight + +If no accepted new occurrence exists, the processor skips mutation and returns under §7.10. + +Otherwise, before the first mutation, it builds the initial participating closure from every accepted-new target and every declared ancestor. For each scope in Root-to-descendant order it: + +- checks direct terminated state; +- snapshots Process Embedded paths; +- recognizes every effective contract type and role; +- validates channel/Handler binding structure; +- validates required dispatch fields and portable limits; +- verifies that every selected external snapshot remains compatible. + +Unsupported or malformed runtime structure produces atomic failure before initialization. + +### 7.5 Phase D — process accepted-new deliveries + +Process accepted-new logical delivery groups in the canonical order of their first participating source occurrence. Raw source occurrences inside one group retain their original canonical order for checkpoint writes. + +Before each delivery: + +1. skip if its scope is cut off, removed, or under a terminated scope; +2. initialize every uninitialized active scope on Root-to-target chain in top-down order; +3. re-check cut-off and termination; +4. invoke the frozen logical delivery using its exact payload and frozen handler Channel; +5. apply every Handler result; +6. call `DRAIN_INTERNAL_EVENTS` exactly once to quiescence; +7. if the delivery scope remains active, nonterminating, and nonterminated, write every participating source checkpoint in canonical raw-source order; +8. call `DRAIN_INTERNAL_EVENTS` again only if a registered checkpoint extension legitimately emitted events; core checkpoint writes never do. + +If Root terminates, later external deliveries are skipped. + +### 7.6 Initialization ordering + +For target `/a/b/c`, uninitialized scopes are initialized: + +```text +/ +/a +/a/b +/a/b/c +``` + +Each scope's initialization lifecycle and caused internal event processing completes before the next descendant scope initializes. This prevents descendant effects from reaching an uninitialized ancestor. + +A scope initialized earlier in the same invocation is not initialized again. + +### 7.7 One external delivery + +For one accepted-new logical delivery group: + +```text +1. Use the frozen payload, handler Channel snapshot, and participating raw source snapshots. +2. Discover current post-initialization same-scope Handlers bound to handlerChannelKey. +3. Sort and freeze candidates. +4. For each candidate: + a. charge and evaluate its matcher; + b. if nonmatching, continue; + c. demand its executable body and declared dependencies; + d. execute with $event = payload and $processingEvent = original event; + e. apply its result under §4.12; + f. after every nested cascade, check active-scope cut-off. +5. Return to Phase D; do not drain the queue here. +``` + +The accepted channel may have no matching Handler. It is still a successful delivery and may be checkpointed. + +### 7.8 Internal event drain + +```text +function DRAIN_INTERNAL_EVENTS(): + while RUN.eventQueue is not empty: + occurrence = dequeue FIFO + + if source occurrence is active and not terminating and not terminated: + DELIVER_TRIGGERED_AT_SOURCE(occurrence) + + for receivingAncestor in occurrence.frozenAncestors nearest-first: + if receivingAncestor is active and not terminating and not terminated: + DELIVER_EMBEDDED_EVENT(receivingAncestor, occurrence) +``` + +Root has no ancestor and therefore cannot be cut off. Root termination does not erase occurrences that were already enqueued. The queue continues to quiescence under the ordinary active/nonterminating predicates and the shared gas limit. No new handler begins in Root after Root is marked terminating, and no later external delivery begins, but nonterminating descendant or intermediate scopes may finish reactions to occurrences already in the FIFO. + +Each delivery performs fresh channel and Handler discovery at that receiving scope, applies results synchronously, and may enqueue later occurrences. + +An occurrence emitted before its source is cut off continues to its frozen ancestors. Cut-off only stops new local work and unapplied buffered source effects. + +### 7.9 Phase E — final soundness and subscription validation + +Before returning success, the processor or its deterministic platform boundary MUST establish: + +- Root and every changed node are valid Blue Language nodes; +- the changed Root spine is type- and schema-sound; +- effective protected state was preserved; +- every changed effective contract type is supported; +- Process Embedded ancestry is acyclic and within limits; +- the changed subscription delta is finite, supported, and incrementally constructible; +- new activation intervals begin after the current external-order key; +- Root events satisfy the return limits. + +A deterministic failure in this phase rolls back the entire invocation. + +Transient inability to persist an already validated index delta is infrastructure suspension and commits nothing. + +### 7.10 Result selection + +If at least one accepted-new occurrence completed, result status is `success`, even when another candidate rejected, was stale, disappeared, or was cut off. + +If no new occurrence completed and at least one accepted occurrence was stale, result status is `stale`. + +If no current occurrence accepted, result status is `no-match`. + +`no-match` and `stale` return input Root and no events. They do not initialize or write checkpoints. + +An invocation that begins with a direct terminated Root returns `terminated`. + +### 7.11 Several matching scopes + +For: + +```text +Root +└── Emb1 + └── Emb2 + └── Emb3 +``` + +canonical external order is: + +```text +Emb3 +Emb2 +Emb1 +Root +``` + +The Emb3 external delivery and all of its caused updates/events complete before the Emb2 external delivery. Emb2 therefore sees Emb3's tentative changes. Root processes the external event last and sees all earlier tentative changes. + +The whole set is one atomic Root transition. A late failure rolls back earlier tentative work for the same external event. + +### 7.12 Exact locality + +Successful processing MUST NOT require semantic expansion or contract discovery of: + +- sibling embedded scopes outside selected branches; +- unrelated descendants; +- rejected external-channel bodies; +- nonmatching Handler bodies; +- unchanged descendant bodies needed only as known BlueIds; +- types, schemas, constants, or programs outside the demanded closure. + +A host MAY prefetch them, but they cannot alter semantic demands, results, or portable gas. + +--- + +## 8. Runtime Pointers, Patches, and Persistent Mutation + +### 8.1 Runtime Pointer + +A Blue Runtime Pointer is an RFC 6901 pointer over the current Root's abstract Blue node model. + +- `""` denotes Root and is forbidden as an application patch target. +- object segments use RFC 6901 escaping; +- list indices are canonical decimal without leading zero; +- `-` is permitted only for list `add` at the end; +- malformed escapes, empty trailing segments, or out-of-range indices are invalid. + +### 8.2 Json Patch Entry + +Core supports: + +```yaml +op: add | replace | remove +path: +val: # required for add/replace; absent for remove +``` + +Operations are applied in result order. A later patch observes all earlier tentative patches and cascades. + +`replace` on an object member is an upsert: the final member may be absent before the operation. `remove` of a missing member is invalid. + +The parent container of the final path segment MUST already exist and have the required object or list kind. Core patch semantics do not synthesize missing intermediate objects or lists. A runtime that wants to create a nested structure must add or replace an admitted complete subtree at an existing parent, or issue earlier patches that create each required parent explicitly. Arrays are never silently invented. + +### 8.3 Insertion normalization + +A value inserted by a patch or emitted as an event MUST: + +- be valid runtime Blue input with no root `blue` directive or unresolved alias; +- have no mixed `blueId` form; +- have one compatible payload kind; +- normalize list placeholders and scalar wrappers; +- preserve exact identity when it is already admitted; +- pay construction and identity work only when content is actually newly constructed or re-identified. + +### 8.4 Persistent copy-on-write + +For a patch to `/x/a` where `/x` is reference-backed: + +1. open only direct nodes on the path; +2. preserve unchanged siblings by exact child BlueId; +3. create the changed leaf or subtree; +4. rebuild `x`'s direct identity; +5. rebuild each changed ancestor to Root; +6. validate the affected closure; +7. deliver the Document Update. + +The old nodes remain immutable. Other references to old `x` are unchanged. + +### 8.5 Object operations + +A rebuilt object processes its complete direct helper map. One field change in a very wide direct object is therefore real linear direct-container work in every representation. + +Object field enumeration uses canonical Unicode code-point key order. Reserved Language and Contracts fields follow their specific rules. + +### 8.6 List operations + +List identity uses the Language fold: + +- append with a verified exact prior list identity recomputes only appended folds; +- replacement at index `i` recomputes the suffix from `i`; +- insertion or removal at `i` recomputes the affected result suffix; +- order and multiplicity are preserved. + +### 8.7 Snapshots + +Document Update `before` and `after` values are immutable exact-node snapshots. An absent side is represented only by the presence Boolean. + +A snapshot may retain a node by exact identity without recursively materializing it. A Handler pays only for content it actually reads. + +### 8.8 Boundary and cut-off validation + +Before every patch, the processor validates §5.7 against the executing scope's entry snapshot. + +After every patch and nested cascade, it checks whether an active scope root was removed or replaced and applies §5.8 before the next buffered effect. + +A patch to the same exact child identity is a no-op for occurrence continuity. An ordinary whole-child replacement with a different identity starts a new occurrence for later external events and does not join the current event. + +### 8.9 Effective protected-state validation + +The processor computes `EFFECTIVE_PROTECTED_STATE` before and after every application patch or generated type write. Pointer nonintersection alone is insufficient. + +If protected state changes outside the exact `Process Embedded.paths` exception, the invocation fails atomically with `ProtectedProcessorStateMutation`. + +### 8.10 Contract-changing patches + +A patch affecting any of these MUST trigger changed-closure recognition before further application execution: + +```text +/type +/contracts +an inherited type contribution +contracts/embedded/paths +another runtime-registered dispatch or subscription dependency +``` + +The processor re-establishes: + +- all effective contract types and roles in the changed closure; +- same-scope bindings; +- protected state; +- external subscription extraction; +- portable limits. + +Unsupported newly installed contract content cannot be committed and deferred to the next event. + +### 8.11 Direct-node limits + +A direct-node limit applies to every node that must be enumerated, validated, or rebuilt, including every ancestor on the changed spine. + +A larger exact node may still be carried opaquely by BlueId. An operation that needs its direct manifest fails deterministically with `DirectNodeLimitExceeded`. + +### 8.12 Cyclic sets + +Core runtime patches MUST NOT enter or structurally modify one member of a cyclic-set identity. A complete cyclic set may be replaced atomically as an already admitted new set. Otherwise processing fails with `CyclicSetMutationUnsupported`. + +Opaque cyclic-member edges are valid ordinary content and may remain untouched through copy-on-write reconstruction. They are not independent processing roots, external events, or embedded-scope roots. Admission, embedded-boundary validation, and patch planning MUST reject unsupported cyclic access before demanding a member body. + +--- + +## 9. Initialization, Lifecycle, and Termination + +### 9.1 Initialization gate + +A scope initializes only when an accepted-new delivery requires that scope to participate. + +These do not initialize a scope: + +```text +preselection false +channel rejection +all accepted occurrences stale +cut-off target +pre-existing terminated scope +capability failure +``` + +### 9.2 Initialization identity + +The Document Processing Initiated event carries the exact scope document as it existed immediately before initialization effects. That node may be carried as a pure reference or verified materialization; both forms are the same document and do not change processing or gas. No Source Document BlueId calculation is performed. + +### 9.3 Initialization algorithm + +For one uninitialized active scope: + +1. freeze its exact pre-initialization scope document and BlueId; +2. mark it `initializing` in run state; +3. create Document Processing Initiated; +4. deliver matching Lifecycle Channels and Handlers; +5. apply their results and enqueue emitted events; +6. call `DRAIN_INTERNAL_EVENTS` to quiescence; +7. re-check cut-off and termination; +8. if still active, nonterminating, and not terminated, Direct Write the Processing Initialized Marker; +9. mark it initialized for this invocation. + +The marker write creates no Document Update. If an ancestor replaces the scope during initialization reactions, no marker is written into the replacement. + +### 9.4 Initialization snapshot rule + +An accepted external channel snapshot remains frozen across initialization. Initialization may add, remove, or replace that channel in the current contracts map, but the already accepted delivery proceeds from its frozen snapshot unless the scope is cut off or terminated. + +Handler discovery occurs after initialization and sees the post-initialization effective contracts map. + +### 9.5 Termination request + +A ContractExecutionResult may request graceful termination with a deterministic application cause and optional reason. The cause explains why the successful business transition is ending; it is not a `graceful | fatal` execution mode. Runtime failure is represented only by a noncommitting failure status. + +The first request for a scope in one invocation wins. Later requests are ignored. A termination request is applied after that result's patches and emitted events have been recorded. + +### 9.6 Termination algorithm + +For one active nonterminating scope: + +1. freeze the first termination request; +2. mark the scope `terminating`; +3. create and deliver Document Processing Terminated; +4. apply lifecycle Handler results; +5. call `DRAIN_INTERNAL_EVENTS` to quiescence; its ordinary-delivery predicate excludes scopes marked `terminating`, so no new local Triggered or Embedded Handler begins in that scope, while event occurrences emitted before or during termination continue to nonterminating frozen ancestors; +6. re-check cut-off; +7. if the scope still exists as the same occurrence, Direct Write the Processing Terminated Marker; +8. mark the scope terminated and stop later local work. + +The marker creates no Document Update. + +A scope may stop reacting while already-emitted descendant event occurrences continue to higher frozen ancestors. + +### 9.7 Root termination + +When Root begins termination: + +- no later external delivery begins; +- the current result's already ordered patches and emissions complete according to §4.12; +- the termination lifecycle completes once; +- the Root termination marker write is attempted and metered under the normal rules; a committing termination requires it to complete; +- the committing status remains `success` because a new Root was produced. + +A later invocation on that Root returns `terminated` immediately. + +There is no fixed-price emergency closeout. If the marker write cannot fit within gas or violates a deterministic rule, the whole invocation rolls back. + +### 9.8 Deterministic failures + +A deterministic runtime failure does not gracefully terminate or write a processor marker. It aborts the tentative invocation, returns the input Root, returns no events, and reports the admitted gas and diagnostic. + +This keeps failure recovery separate from business termination and avoids partially committed fatal state. + +--- + +## 10. Checkpoints and Idempotency + +### 10.1 Checkpoint marker + +Each scope MAY contain one direct Channel Event Checkpoint at: + +```text +contracts/checkpoint +``` + +Conceptually: + +```yaml +contracts: + checkpoint: + type: Channel Event Checkpoint + entries: + : + domain: + blueId: + subject: + blueId: +``` + +Checkpoint state is direct processor state and is never inherited. + +### 10.2 Checkpoint domain + +A checkpoint entry is active only when its `domain` equals the current frozen channel's `checkpointDomainBlueId`. + +The default domain is the BlueId of a canonical domain node containing: + +```text +Contracts version tag +External Channel effective type BlueId +ordered source-contribution BlueIds +runtime-registered checkpoint-domain discriminator +``` + +A concrete channel type may define another exact domain derivation. It MUST be stable, representation-independent, and registered. + +Changing a channel's type or effective contributions at the same key therefore does not silently inherit an unrelated prior channel's stale state. + +### 10.3 Virtual empty state + +An absent checkpoint marker, absent raw key, or domain mismatch is treated as virtual empty state for newness evaluation. + +The processor MUST NOT create an empty marker before establishing that a delivery is accepted, new, and successful. + +### 10.4 Default exact-node subject + +The default checkpoint subject is the exact input event BlueId retained as a pure reference. + +A channel is stale when the current active entry has the same domain and the registered newness policy says the subject is not new. A concrete channel may use timeline predecessor, sequence, or another deterministic subject, but its policy and work are part of that exact runtime type. + +Checkpointing uses the exact input event BlueId by default; it does not run Source Document BlueId calculation. + +### 10.5 Atomic checkpoint write + +The checkpoint entry is Direct Written only after: + +- accepted Channel delivery; +- all matching external Handlers; +- all caused patches and Document Updates; +- all caused internal event processing; +- successful termination handling, if requested; +- confirmation that the delivery scope remains the same active occurrence. + +The checkpoint and every delivery effect commit together with Root. The write creates no Document Update. + +### 10.6 Checkpoint cleanup and domain retirement + +Checkpoint state is processor-owned and MUST NOT grow indefinitely after channels disappear or change semantic lineage. + +At final changed-closure recognition, the processor deterministically compares the direct checkpoint entries of each changed scope with the scope's final effective External Channels: + +- an entry whose raw channel key no longer exists is removed; +- an entry whose stored domain is not the current channel checkpoint domain is removed unless that exact runtime type defines an identity-bound migration accepted by this specification; +- an unchanged key with the unchanged domain is retained; +- cleanup is a processor Direct Write, creates no Document Update, and pays normal pointer, changed-direct-identity, validation, and `processorMarkerWritten` work; +- cleanup is tentative and rolls back with the invocation. + +A channel removed and later re-added therefore starts with virtual empty checkpoint state unless an exact registered migration rule says otherwise. + +### 10.7 Multiple occurrences and retry + +The same external event may be accepted by several channels in several scopes. Each `(scope occurrence, raw channel key, checkpoint domain)` has independent newness. + +After uncertain platform commit, the feeder reloads authoritative Root and revision: + +- if the new Root committed, checkpoints make previously completed occurrences stale; +- if the old Root remains, the event is recomputed from that Root; +- if another Root is current, a new revision-bound delivery snapshot is derived. + +The external event is never rewritten for retry. + + +--- + +## 11. Type Soundness, Generalization, and Subscription Indexability + +### 11.1 Post-write soundness + +After every successful patch, generated write, or processor Direct Write, the processor MUST restore the exact soundness obligations applicable to the changed closure before unrelated execution continues. + +For application and generated writes, this includes: + +- Blue Language node validity; +- fixed-value, type, schema, and collection compatibility; +- root-spine validity through every rebuilt ancestor; +- protected-state equality; +- supported effective contracts in the changed closure; +- valid Process Embedded structure and boundaries. + +Processor Direct Writes validate their own marker shape and the rebuilt Root spine but do not execute application Document Update Channels. + +### 11.2 Root-spine validation + +A deep embedded patch is not valid merely because the local child remains valid. Every changed ancestor from the patch location to Root MUST remain valid under its effective type and schema. + +Validation may retain unchanged child nodes by exact BlueId. It does not require transitive expansion of unchanged descendants unless their semantics are actually needed by a changed ancestor constraint. + +### 11.3 Type Generalization Policy + +A scope MAY contain a direct or inherited Type Generalization Policy at `contracts/generalization`. The effective policy is protected state. + +A policy contains ordered rules. Each rule identifies a path, mode, and optional floor type: + +```text +mode = nearest-valid-ancestor | reject +mustRemainSubtypeOf = optional exact type BlueId +``` + +The most specific matching path wins; ties use rule order. If no rule matches, the policy's `defaultMode` applies; absent default is `reject`. + +### 11.4 Nearest-valid-ancestor algorithm + +When a changed node no longer conforms to its current effective type and policy permits generalization: + +1. record the current explicit/effective type as candidate `T0`; +2. validate the changed node against `T0`; +3. if invalid, move to the immediate effective ancestor type `T1`; +4. test candidates upward one at a time; +5. reject a candidate violating `mustRemainSubtypeOf`; +6. choose the first valid candidate; +7. if no valid candidate exists before the floor or root of the chain, fail. + +Candidate order is exact type-chain order. A processor MUST NOT search unrelated types or choose a more general type when a nearer valid ancestor exists. + +### 11.5 Generated write order + +A generated type write is applied immediately after the patch that required it and before that patch's Document Update is delivered. + +The generated write: + +- is a processor-generated application-visible change; +- creates its own Document Update occurrence; +- is subject to protected-state validation; +- may trigger changed-contract recognition and subscription-delta validation; +- pays ordinary pointer, identity, validation, and update gas. + +Generated writes cannot specialize a node or invent a type not on the existing ancestor chain. + +### 11.6 Changed contract closure + +When type or contract contributions change, the processor MUST resolve every affected effective contract type before commit. An unsupported External Channel, Process Embedded marker, Handler, lifecycle contract, or executable extension makes the new Root invalid for Contracts processing and rolls back the invocation. + +Executable bodies remain lazy; recognition does not execute them. + +### 11.7 Subscription-delta validation + +Before a new Root can commit, the deterministic changed subscription delta MUST prove: + +- every changed Process Embedded exact path and collection path is valid; +- every present exact child, collection container, and direct collection member has the required object shape; +- every generated concrete collection-member path is unique and canonical; +- no declared embedded ancestry cycle exists; +- embedded depth, scope, key, and header limits hold; +- terminated-subtree pruning is deterministic; +- every changed External Channel type has supported subscription functions; +- its snapshot, keys, checkpoint domain, and activation interval can be derived; +- new intervals begin strictly after the current event order key; +- retired intervals are closed at the new Root revision; +- the incremental index delta is finite and canonical. + +The validator may examine only changed branches and dependencies plus retained index identities. It MUST NOT require a full recursive Root scan for every event. + +A deterministically non-indexable new Root fails with `SubscriptionSurfaceInvalid`. A transient failure to persist a valid delta is infrastructure suspension and commits nothing. + +--- + +## 12. Failure, Resource, Status, and Progress Semantics + +### 12.1 Statuses + +Core statuses are: + +| Status | Commits a new Root? | Meaning | +|---|---:|---| +| `success` | Yes | At least one accepted-new external occurrence completed. | +| `no-match` | No | No current External Channel accepted the event. | +| `stale` | No | At least one Channel accepted, but no accepted occurrence was new. | +| `terminated` | No | Root already had a valid direct terminated marker. | +| `invalid-processing-document` | No | Root or event was invalid before semantic execution. | +| `capability-failure` | No | A required runtime type or role was unsupported. | +| `runtime-fatal` | No | Deterministic processing failed after admission. | +| `gas-limit-exceeded` | No | The next canonical charge could not be admitted. | +| `portable-limit-exceeded` | No | A published portable structural or occurrence limit was exceeded. | +| `subscription-surface-invalid` | No | The input or resulting Root could not have a canonical subscription surface. | + +A committing Root termination is still `success`; a later invocation returns `terminated`. + +### 12.2 Diagnostic categories + +Appendix B defines exact diagnostic categories. A diagnostic MUST include enough deterministic context for conformance, such as scope path, contract key, runtime type, patch path, or limit name, without embedding host stack traces or nonportable messages. + +### 12.3 Admission and deterministic failure + +Malformed serialized input, a missing exact Root identity, or an invalid event may be rejected before the gas meter begins and therefore reports zero gas. + +After `processInvocation` is admitted, every deterministic semantic operation charges before work. A later capability, validation, patch, runtime, or limit failure returns the input Root, no events, and the gas admitted before the failure. + +There is no separate zero-gas tentative preflight ledger and no portable `attemptedWork` result. This makes expensive rejected work visible to the same deterministic budget. + +### 12.4 Resource acquisition boundary + +Core `PROCESS` operates on verified exact-node evidence. Deterministic execution MUST NOT perform ambient network I/O. + +An implementation MAY expose an attempt API: + +```text +PROCESS_ATTEMPT(root, event, verifiedEvidence) + -> Complete(ProcessResult) + | NeedsResources(sortedExactBlueIds) +``` + +`NeedsResources` is a suspension, not a `ProcessResult`: + +- it commits no Root, events, checkpoint, marker, progress, or portable gas; +- the host fetches and verifies direct nodes outside deterministic execution; +- retry starts from the exact input Root and event; +- hidden cache state MUST NOT turn the same explicit evidence set into a different attempt outcome. + +Provider transfer, direct-node verification, signatures, storage pages, and retry count are host work. Once an exact node is admitted, semantic inspection and new/changed identity work are charged normally and identically to inline content. + +### 12.5 Definitive missing content and invalid evidence + +A configured provider domain may report definitive `NotFound`; evidence may fail BlueId verification. These are host acquisition failures unless the exact runtime type deliberately treats one as application data. + +No implementation may convert unavailable, incomplete, or invalid evidence into semantic field absence. + +### 12.6 Gas exhaustion + +Every charge is admitted before the corresponding work. If the next charge would exceed `MAX_PROCESS_GAS`: + +- the failing charge is not added; +- no further runtime or lifecycle code runs; +- every tentative mutation, event, marker, checkpoint, and queue item is discarded; +- the result is `gas-limit-exceeded`, input Root, empty events, and already admitted gas. + +There is no fixed-price termination closeout. + +A repeated attempt against the same Root revision, event, environment, and gas limit produces the same status, trace prefix, and gas. + +### 12.7 Portable limits + +A limit known before the meter begins may be rejected with zero gas by the feeder or admission layer. A limit discovered after semantic execution begins returns `portable-limit-exceeded` with admitted gas. `NeedsResources` is never encoded as `ProcessResult.status`; it exists only as the alternate result of `PROCESS_ATTEMPT`. + +The diagnostic MUST identify the exact limit, such as: + +```text +MatchingDeliveryLimitExceeded +ParticipatingScopeLimitExceeded +DirectNodeLimitExceeded +EmbeddedDepthLimitExceeded +InternalEventLimitExceeded +PatchLimitExceeded +RuntimeLedgerLimitExceeded +``` + +### 12.8 Failure precedence + +When several errors are possible, the normative algorithm order decides. In particular: + +1. invalid Root/event admission precedes runtime discovery; +2. direct terminated state precedes application contract recognition; +3. delivery revalidation precedes Channel acceptance; +4. checkpoint comparison precedes initialization; +5. cut-off checks precede remaining buffered effects and marker writes; +6. gas exhaustion occurs at the first unadmitted canonical charge. + +Fixtures asserting one diagnostic MUST isolate the relevant failure or list acceptable categories explicitly. + +### 12.9 Revision-bound progress + +The feeder MUST record every terminal outcome only by compare-and-swap against the exact Root revision on which it was calculated. A progress-only terminal record (`no-match`, `stale`, failure, or gas exhaustion) cannot be committed after Root has changed. + +A Root-mutating `success` commits Root, Root events, subscription delta, and progress together. A failed compare-and-swap records nothing and triggers recomputation. + +### 12.10 External-event liveness + +A deterministic poison event MUST NOT cause unbounded automatic retries or permanently block all later external events. + +After one revision-bound terminal failure, the platform MUST either: + +- quarantine the event and advance according to declared platform policy; +- require explicit administrative retry; +- or change the Root/environment before retrying. + +The policy is audited outside Root but may not silently reinterpret a failed event as success. + +--- + +## 13. Canonical Gas Accounting + +### 13.0 Schedule status + +The counter vocabulary, ownership, formulas, and canonical trace order are normative for this implementation baseline. The numeric weights and portable-limit values are provisional pending calibration and are loaded from the bound gas manifest. Implementations MUST load or generate them from that artifact rather than scatter duplicated constants through runtime code. Final public Contracts 1.0 publication freezes the calibrated values once and regenerates every dependent fixture and package identity. + + +### 13.1 Governing principle + +Gas prices deterministic logical work, never the chosen materialization. + +For the same exact node `X`: + +```yaml +x: + a: 1 + b: 1 +``` + +and: + +```yaml +x: + blueId: X +``` + +must produce the same trace when the same logical fields are inspected and the same transition is performed. + +An existing exact node is cheap to carry. Content costs gas when it is inspected, compared, constructed, normalized, validated, or re-identified. + +### 13.2 One disjoint ledger + +```text +totalGas = + weighted processor counters + + weighted semantic counters + + weighted runtime counters +``` + +One logical unit increments one named counter. A reason tag never adds another numeric category. The same work MUST NOT be charged once as “admission” and again as “changed identity.” + +### 13.3 Canonical trace record + +In conformance mode, every admitted charge is appended before work as: + +```text +GasTraceEntry { + sequence + namespace + counter + quantity + weight + subtotal + scopePath? + contractKey? + logicalPath? + reason +} +``` + +Entries are ordered by the normative algorithm. `sequence` begins at zero and increases by one per trace entry. A charge with quantity greater than one remains one trace entry unless the rule explicitly requires per-occurrence entries. + +An ordinary API may return only `totalGas`, but a conforming implementation MUST be able to produce the exact trace for the fixture harness. + +### 13.4 Shared live-bounded meter + +Processor work, semantic Language work, external channels, Handlers, workflows, executable runtimes, and registered intrinsics share one meter. + +A runtime child meter receives the exact remaining budget. It admits every child charge live. Its ledger is merged once in original order. A runtime-local gas limit may only lower the available budget; it cannot replenish it. + +### 13.5 Processor counters and weights + +| Counter | Weight | +|---|---:| +| `processInvocation` | 50 | +| `deliverySnapshotEntry` | 5 | +| `scopeOpened` | 10 | +| `contractHeaderRecognized` | 2 | +| `channelCandidateTested` | 5 | +| `channelAccepted` | 5 | +| `handlerCandidateTested` | 5 | +| `handlerCall` | 50 | +| `scopeInitialization` | 1000 | +| `embeddedPathEntryRead` | 1 | +| `embeddedPathSegmentValidated` | 1 | +| `pointerSegmentTraversed` | 1 | +| `patchBoundaryChecked` | 2 | +| `patchAddOrReplace` | 20 | +| `patchRemove` | 10 | +| `documentUpdateDelivered` | 10 | +| `internalEventEnqueued` | 20 | +| `internalEventDequeued` | 10 | +| `triggeredEventDelivered` | 10 | +| `embeddedEventDelivered` | 10 | +| `rootEventRecorded` | 5 | +| `lifecycleDelivered` | 30 | +| `checkpointCompared` | 5 | +| `checkpointWritten` | 20 | +| `processorMarkerWritten` | 20 | +| `terminationRequested` | 10 | + +Rules: + +- `deliverySnapshotEntry` is charged once per retained entry revalidated by the processor. +- `scopeOpened` is charged once per distinct active scope occurrence in one invocation. +- `contractHeaderRecognized` is charged once per `(scopePath, key, ordered contribution identities)`. +- `embeddedPathEntryRead` is charged once for every effective entry read from `paths` or `collectionPaths` and once for every concrete direct member path generated from a collection declaration; +- every segment of an explicit declaration path, collection path, or generated concrete member path pays `embeddedPathSegmentValidated` when validated; +- opening a present collection target pays the ordinary semantic `nodeManifestOpened` charge, and enumerating its complete direct ordinary key set pays `objectMemberRead` once per direct member; collection enumeration is not free feeder folklore and is representation-invariant; +- a Channel or Handler candidate pays its test charge even when it rejects; +- a delivery counter (`documentUpdateDelivered`, `triggeredEventDelivered`, `embeddedEventDelivered`, `lifecycleDelivered`) is charged only for a matching Channel delivery, in addition to candidate tests; +- `rootEventRecorded` is charged only for Root emissions, not child emissions. + +### 13.6 Semantic counters and weights + +| Counter | Weight | +|---|---:| +| `nodeManifestOpened` | 1 | +| `objectMemberRead` | 1 | +| `listItemRead` | 1 | +| `textBlockExamined` | 1 | +| `textBlockConstructed` | 1 | +| `scalarComparison` | 1 | +| `integerLimbOperation` | 1 | +| `sortComparison` | 1 | +| `typeEdgeFollowed` | 1 | +| `schemaPredicateEvaluated` | 1 | +| `validationMemberExamined` | 1 | +| `validationProofReused` | 1 | +| `subtypeCandidateTested` | 5 | +| `nodeIdentityEstablished` | 1 | +| `objectMemberRebuilt` | 1 | +| `listFoldStepRecomputed` | 1 | +| `directIdentityHashBlock` | 1 | + +### 13.7 Manifest and immutable-read rules + +Opening the direct manifest of an exact node for the first semantic use in one invocation charges `nodeManifestOpened` once for that exact BlueId. A second semantic operation may reuse the retained immutable manifest without another manifest-open charge. + +Known-key object access charges `objectMemberRead` each time the normative algorithm examines that member, unless the value was explicitly bound and reused within the same algorithmic step. Complete enumeration charges once per direct member in canonical key order. + +List access charges `listItemRead` per position examined. + +Hidden caches from earlier invocations never reduce the canonical first-use trace. + +Provider-side BlueId verification is outside portable gas. Establishing the identity of new or changed content inside the invocation is charged under §§13.12–13.13. + +### 13.8 Text and scalar work + +One text block contains up to 64 Unicode code points. + +A full scan of Text `t` charges: + +```text +textBlockExamined += ceil(codePointLength(t) / 64) +``` + +A newly constructed Text charges the same block formula as `textBlockConstructed`. + +Lexicographic comparison examines code points until the first difference or the end of the shorter Text. Let `k` be the number of code points whose values are read from each operand, including the differing position when present. It charges: + +```text +scalarComparison += 1 +textBlockExamined += ceil(k / 64) for the left operand +textBlockExamined += ceil(k / 64) for the right operand +``` + +Length-only comparison after a fully equal prefix does not reread content. + +Exact Blue node identity equality may compare known BlueIds without scanning transitive content. Runtime value equality that is not exact Blue identity follows the runtime specification. + +### 13.9 Integer work + +Integers use a canonical unsigned base-`2^32` magnitude and separate sign. `L(x)` is at least 1 and otherwise the number of limbs. + +| Operation | `integerLimbOperation` quantity | +|---|---:| +| equality or ordering | `L(a) + L(b)` | +| addition or subtraction | `max(L(a), L(b)) + 1` | +| multiplication | `L(a) * L(b)` | +| division or remainder | `L(a) * L(b)` | +| GCD or `multipleOf` | `L(a) * L(b)` | +| LCM | GCD quantity plus multiplication quantity | + +The formula defines portable work, not a required host algorithm. + +### 13.10 Canonical sorting + +When processor semantics require sorting a candidate set, canonical gas is calculated as if using stable bottom-up merge sort: + +1. input order is canonical contract-key order or another explicitly defined order; +2. runs begin at width 1; +3. adjacent runs merge left-to-right; +4. run width doubles after each pass; +5. equal comparisons select the left element; +6. every comparator call charges `sortComparison` plus content work for compared fields. + +Implementations may use another physical algorithm but MUST report this canonical trace. + +External event ordering and subscription-index lookup are feeder work and do not use this processor counter. + +### 13.11 Type, contract, and validation work + +Effective contracts are merged ancestor-to-descendant: + +- charge `typeEdgeFollowed` for each traversed type edge; +- enumerate demanded contribution maps; +- inspect only registered dispatch fields; +- charge one `contractHeaderRecognized` for the effective snapshot. + +Validation charges: + +- `schemaPredicateEvaluated` per predicate; +- `validationMemberExamined` per collection member examined by `itemType`, `keyType`, `valueType`, `uniqueItems`, enum search, or another member-wise rule; +- `subtypeCandidateTested` per generalization/subtype candidate; +- Text and Integer work for scalar content examined. + +Within one invocation, an exact successful proof for: + +```text +(nodeBlueId, effectiveTypeBlueId, effectiveConstraintIdentity) +``` + +is charged in full once. Later logical reuse increments `validationProofReused` once and does not repeat predicate/member counters. Cross-invocation caches are physical optimization only and do not remove the current invocation's first full proof. + +### 13.12 Identity establishment + +Every new exact node, including an empty list, charges: + +```text +nodeIdentityEstablished += 1 +``` + +For a new or rebuilt non-list node: + +```text +objectMemberRebuilt += direct helper-map members processed +directIdentityHashBlock += ceil((N + 9) / 64) +``` + +`N` is the UTF-8 byte length of the exact RFC 8785 canonical direct identity input hashed for that node. Transitive child bodies are replaced by their exact bounded canonical Base58 child BlueId strings before `N` is measured. Direct keys, `name`, `description`, and inline scalar `value` contribute because the Language BlueId algorithm hashes them directly. + +This is actual changed/new identity work. Carrying an existing exact node never pays it again. + +### 13.13 List identity + +For a new or changed list: + +- full construction charges one `listFoldStepRecomputed` per result element; +- append from a verified prior exact list identity charges appended steps only; +- replacement at index `i` charges the result suffix from `i`; +- insertion/removal at `i` charges the affected result suffix. + +The fixed list-cons hash input is represented by the fold counter and is not charged again as `directIdentityHashBlock`. + +### 13.14 Runtime ledger composition + +Each executable runtime type publishes exact named counters and weights in its own specification and runtime registry. + +Runtime construction work and semantic identity admission are distinct: + +```text +A concrete compute runtime creates a 100-member object: + that runtime charges members produced. + +The value crosses a Blue output/patch boundary: + Contracts/Language charges node identity and direct-container work. +``` + +Passing an existing exact Blue node charges only the runtime access/carry work actually defined by that runtime; it does not recursively size or reconstruct the node. + +### 13.15 Patch trace + +A successful patch charges, in order: + +```text +patchBoundaryChecked +pointerSegmentTraversed for each segment +patchAddOrReplace or patchRemove +runtime construction, when the value was newly built +identity establishment for changed leaf and every rebuilt ancestor +post-write type/schema/generalization work +Document Update candidate tests and matching deliveries +downstream Handler/runtime work +``` + +It does not charge unchanged transitive descendants behind known child BlueIds. + +### 13.16 Event and checkpoint trace + +Emitting an existing exact event has no recursive size charge. A newly constructed event pays runtime construction and semantic identity admission before `internalEventEnqueued`. + +A Root emission additionally pays `rootEventRecorded`. + +Checkpoint comparison pays `checkpointCompared` and the exact subject policy work. A checkpoint write pays `checkpointWritten`, marker pointer work, direct changed identity, and validation. It creates no Document Update. + +### 13.17 Zero-gas physical work + +The following consume zero portable Contracts gas: + +```text +provider lookup and transfer +provider BlueId verification +cache hit, miss, fill, or eviction +storage page/chunk access +physical prefetch +allocation and host copying +hash-cache lookup +transport serialization +subscription-index maintenance/query +external-source completeness queries +external event sorting +failed compare-and-swap and recomputation +``` + +Hosts may meter, bill, or quota them separately. + +### 13.18 Representation example + +Suppose: + +```yaml +x: + a: 1 + archive: + blueId: <25-MiB-archive> +``` + +and an equivalent Root has `x` collapsed to its BlueId. For: + +```yaml +op: replace +path: /x/a +val: 2 +``` + +both forms perform and charge the same semantic trace: + +1. open Root direct manifest; +2. open `x` direct manifest; +3. traverse `/x/a`; +4. admit scalar `2`; +5. rebuild `x` using the unchanged archive BlueId; +6. rebuild ancestors to Root; +7. validate changed closure; +8. deliver caused updates and events. + +The archive body is neither demanded nor charged. A one-million-field direct `x` remains expensive in both forms because its direct manifest is real identity work. + +### 13.19 Worked processor subtotal (informative) + +Assume one already admitted external event has: + +```text +one retained raw delivery +two participating scopes +four effective contract headers +one Channel candidate that accepts +one Handler candidate that executes +one two-segment patch path /x/a +no initialization in this example +``` + +The processor-counter subtotal before semantic reads, runtime work, identity rebuilding, validation, updates, checkpoints, or sorting is: + +```text +processInvocation 1 * 50 = 50 +deliverySnapshotEntry 1 * 5 = 5 +scopeOpened 2 * 10 = 20 +contractHeaderRecognized 4 * 2 = 8 +channelCandidateTested 1 * 5 = 5 +channelAccepted 1 * 5 = 5 +handlerCandidateTested 1 * 5 = 5 +handlerCall 1 * 50 = 50 +pointerSegmentTraversed 2 * 1 = 2 +patchBoundaryChecked 1 * 2 = 2 +patchAddOrReplace 1 * 20 = 20 + ---- +processor subtotal 172 +``` + +`172` is deliberately only a subtotal. The complete gas also includes the exact semantic and runtime counters actually caused by the concrete nodes and handler. Conformance fixtures, not this illustrative example, define complete exact traces. + +--- + +## 14. Determinism, Security, and Portable Limits + +### 14.1 Deterministic execution + +Contract behavior MUST NOT depend on: + +- wall-clock time; +- randomness; +- ambient network reads; +- CPU speed or thread scheduling; +- host object identity; +- cache warmth; +- database row order; +- locale-sensitive comparison; +- noncanonical map iteration; +- unspecified numeric behavior. + +External time and actor attribution enter only through the immutable event and feeder evidence fixed before processing. + +### 14.2 Read-only values + +Event nodes, snapshots, dispatch snapshots, and runtime context are read-only. All application mutation occurs through Json Patch Entries. All application event output occurs through the normalized result. + +A host MUST NOT require recursive cloning to enforce read-only behavior. Immutable identity-preserving values are sufficient. + +### 14.3 Trust boundary + +The processor trusts the managing feeder to supply a complete revision-bound snapshot and correct external-order evidence. It revalidates every selected branch and channel identity but does not independently rescan the complete subscription surface. + +The trust boundary is: + +| Input or claim | Core treatment | +|---|---| +| Root, event, type, body, and demanded node content | Must have verified exact BlueId evidence. | +| Delivery path and channel contribution identity | Revalidated against the admitted Root and retained snapshot. | +| Completeness of the preselected occurrence set | Feeder/platform obligation; an omission is nonconformance. | +| Cross-source external order | Bound by the exact policy identity and completeness evidence under §3.6. | +| Runtime semantics | Selected by exact runtime-type BlueId and registry binding. | +| Authorization or mandate eligibility | Feeder/provider responsibility unless a runtime type adds deterministic checks. | +| Cache, provider transport, database order, host scheduling | Never trusted as semantic input. | + +The processor fails closed on invalid or incomplete evidence. It does not reinterpret unavailable content as absence and does not silently broaden its trust in a warm cache or provider. + +### 14.4 Portable limits + +| Limit | Value | +|---|---:| +| `MAX_PROCESS_GAS` | 100,000 | +| Effective contracts in one participating scope | 8,192 | +| External Channels in one scope | 2,048 | +| Handlers bound to one delivery | 4,096 | +| Subscription keys from one Channel | 256 | +| Preselected external occurrences for one event | 1,024 | +| Participating scopes for one event | 4,096 | +| Combined concrete Process Embedded child paths in one scope | 4,096 | +| Process Embedded declaration entries (`paths` + `collectionPaths`) | 4,096 | +| Embedded depth | 256 | +| Runtime Pointer segments | 256 | +| Normalized Runtime Pointer UTF-8 bytes | 4,096 | +| Contract-key Unicode code points | 256 | +| Contract-key UTF-8 bytes | 1,024 | +| Direct object entries materialized/rebuilt | 16,384 | +| Direct list items materialized/rebuilt | 16,384 | +| Direct canonical identity input bytes | 1,048,576 | +| Type-chain edges | 256 | +| Patches in one ContractExecutionResult | 1,024 | +| Events in one ContractExecutionResult | 1,024 | +| Internal EventOccurrences in one invocation | 8,192 | +| Root events returned | 4,096 | +| Nested Document Update cascade depth | 256 | +| Runtime child-ledger counter kinds | 256 | +| Direct object-key Unicode code points | 4,096 | +| Direct inline identity Text code points | 262,144 | + +These are structural bounds, not promises that maximum-size valid structures fit under `MAX_PROCESS_GAS`. Gas is the operative work ceiling. + +Limits fall into two classes: + +```text +preflight structural limits + may be established before semantic execution and fail with the named + portable-limit diagnostic, possibly with zero gas under §12.7; + +execution safety limits + stop pathological growth during processing but may be dominated by the + earlier gas ceiling under the bound manifest. +``` + +The release manifest and fixtures MUST define failure precedence for every limit. A listed safety limit is not a promise that its dedicated diagnostic is independently reachable under every gas schedule. If the calibrated gas ceiling necessarily triggers first, `gas-limit-exceeded` is the conforming result. A future manifest with different calibrated values may make the structural diagnostic reachable without changing the semantic rule. + +A host MAY impose lower operational quotas. It MUST NOT raise the portable gas or structural limits and still claim the same portable Contracts 1.0 execution environment unless the higher values are bound by a distinct environment identity and the resulting behavior is not presented as portable Contracts 1.0 conformance. + +The direct-container limit applies to every rebuilt ancestor. A larger exact node can be carried opaquely, but an operation requiring its direct manifest fails. + +### 14.5 Bounded feeder work + +The feeder MUST also bound: + +```text +active index entries per managed Root +subscription-key bytes +external event-header demand +preselection work +activation intervals +retained delivery snapshot size +``` + +Hosted numeric quotas may be stricter than the portable processor limits. They MUST be declared before admission and must not change the semantic result of an admitted event. + +### 14.6 Authoring guidance + +Authors SHOULD: + +- use bounded-fanout structures for large mutable collections; +- place large workflow bodies, constants, and templates behind BlueId references; +- keep External Channel headers and subscription keys small; +- put mutable business conditions in Handlers, not External Channel acceptance; +- avoid broad events matching thousands of scopes; +- preserve event/gas headroom for ancestor reactions; +- model independent shared objects as autonomous roots; +- use stable object keys for dynamic embedded collections; +- avoid list positions as process-occurrence identities; +- instantiate reusable process modules with explicit local Channel bindings rather than implicit parent lookup. + +A useful lower-bound estimate before type, schema, text, sorting, runtime, mutation, and identity work is: + +```text +base scan gas ~= + 50 # processInvocation + + 5 * preselected raw occurrences + + 10 * distinct participating scopes + + 2 * recognized effective contract headers + + 5 * Channel and Handler candidates tested +``` + +The exact trace is defined by §13 and the bound manifest. This estimate is authoring guidance only, but it makes clear that the structural maxima are not practical per-event targets. + +### 14.7 Locality conformance + +A processor is not conforming to the locality rules merely because it returns correct gas while still requiring a complete graph materialization. Conformance locality fixtures record exact semantic node demands. A processor MUST be able to complete them without demanding listed unrelated sibling bodies. + +An implementation may physically prefetch those bodies, but they must remain outside the semantic-demand report and cannot be required for success. + +--- + +## 15. Conformance Vectors + +The prose rules, runtime registry, gas manifest, and machine-readable fixture package form one conformance surface. A conforming implementation MUST pass every vector and every fixture bound by the release manifest. + +The 100 vectors are organized by the processor phase or invariant they exercise. One executable fixture may cover several vectors. + +### 15.1 Representation and locality + +- **C-REP-01.** Inline and pure-reference forms of the same Root produce the same status, resulting Root, Root events, semantic demands, counter trace, and gas. +- **C-REP-02.** A patch inside a collapsed branch demands only nodes on the path and semantic dependencies, not sibling bodies. +- **C-REP-03.** Warm/cold cache, batching, prefetch, and physical segmentation do not change portable results or gas. +- **C-REP-04.** Existing large exact values can be carried, emitted, and checkpointed without recursive size work. +- **C-REP-05.** Newly constructed large values pay runtime construction and semantic identity work. +- **C-REP-06.** A wide direct ancestor is charged and limited in every representation. +- **C-REP-07.** An early list edit pays the recomputed suffix; append pays only the delta when prior identity is available. + +### 15.2 Feeder, subscriptions, and external order + +- **C-FEED-01.** The subscription index is revision-complete before event selection. +- **C-FEED-02.** `ACCEPTS => PRESELECTS` and `PRESELECTS => key intersection` hold for every portable External Channel. +- **C-FEED-03.** External Channel acceptance cannot depend on mutable Root state. +- **C-FEED-04.** Physical index false positives are filtered before canonical ordering and limits. +- **C-FEED-05.** An omitted true preselection is feeder nonconformance, not `no-match`. +- **C-FEED-06.** A new Channel begins strictly after the event that introduced it. +- **C-FEED-07.** Removed and re-added semantic Channel contributions create a new activation interval. +- **C-FEED-08.** All deliveries of one event complete before a later external event begins. +- **C-FEED-09.** Nonmutating terminal progress is compare-and-swap bound to the exact Root revision. +- **C-FEED-10.** Repeated deterministic poison events are quarantined rather than retried forever. +- **C-FEED-11.** A concrete channel-specific target key may route one event to one collection member even when many members reuse the same external source; target derivation remains runtime-specific. + +### 15.3 Routing, discovery, snapshots, and initialization + +- **C-DISC-01.** Direct terminated state is checked before application contract recognition. +- **C-DISC-02.** Every effective contract type in the initial participating closure is recognized before first mutation. +- **C-DISC-03.** Unselected executable bodies remain collapsed. +- **C-DISC-04.** Effective contracts use ordered contribution identities rather than a synthetic merged BlueId. +- **C-DISC-05.** A Handler snapshot survives same-delivery contract mutation. +- **C-DISC-06.** Contract/type changes are re-recognized before commit. +- **C-INIT-01.** `no-match` and all-stale processing do not initialize. +- **C-INIT-02.** Ancestors initialize Root-to-target before descendant processing. +- **C-INIT-03.** Accepted Channel/payload/checkpoint snapshot remains frozen across initialization. +- **C-INIT-04.** Handler discovery after initialization sees post-initialization contracts. +- **C-INIT-05.** Initialization marker writes do not create Document Updates. +- **C-ROUTE-01.** The default handler Channel equals the accepted source Channel and preserves existing one-source behavior. +- **C-ROUTE-02.** A declared peer same-scope Channel may be frozen as handler target without being externally evaluated or checkpointed. +- **C-ROUTE-03.** Exact absent and present-non-Channel target lookups remain distinguishable; unavailable or undeclared evidence fails closed. +- **C-ROUTE-04.** Several fresh sources with the same logical delivery key, target, and payload execute handlers once and checkpoint every source only after success. +- **C-ROUTE-05.** A stale source does not piggyback on a fresh source in the same logical group. +- **C-ROUTE-06.** Group target or payload disagreement fails atomically before mutation. +- **C-INIT-06.** The initialization marker and initiated event carry the exact initial scope document; inline and pure-reference forms yield the same Root, lifecycle behavior, gas, and trace. + +### 15.4 Embedded scopes, updates, and events + +- **C-EMB-01.** External deliveries are ordered deeper-first, then path, order, and key. +- **C-EMB-02.** One external event produces one atomic Root transition across all selected scopes. +- **C-EMB-03.** Unrelated embedded branches are not semantically demanded. +- **C-EMB-04.** A parent may replace an immediate child root but may not patch inside it. +- **C-EMB-05.** Strict-ancestor patches intersecting child roots are rejected. +- **C-EMB-06.** Active-scope replacement cuts off remaining buffered effects and marker/checkpoint writes. +- **C-EMB-07.** Re-adding a path does not resurrect the old occurrence in the current invocation. +- **C-EMB-08.** `collectionPaths` expands direct object members into concrete embedded scopes in canonical key order; the collection container is not implicitly a scope. +- **C-EMB-09.** A collection target must be object-compatible; lists, non-object members, wildcard syntax, reserved-field traversal, and cyclic-member boundaries fail closed. +- **C-EMB-10.** A collection member added by event `E` does not participate in `E` and begins its subscription interval strictly after `E`. +- **C-EMB-11.** Removing a collection member retires its occurrence; re-adding the same key creates a fresh interval and checkpoint lineage. +- **C-EMB-12.** Exact paths, collection declarations, and generated concrete member paths must not overlap or duplicate one another. +- **C-EMB-13.** The same exact child node at two collection keys creates two independent scope occurrences with independent checkpoints and state transitions. +- **C-EMB-14.** Embedded scope contracts are same-scope and self-contained; parent and ancestor contract keys are not imported or searched. +- **C-EMB-15.** A local Channel bound inline and the same exact Channel bound by pure BlueId reference produce identical processing, subscription, checkpoint, gas, and trace behavior. +- **C-EMB-16.** Changing a parent Channel does not silently rebind an existing child; a newly created child may explicitly use the new binding. +- **C-UPD-01.** Every successful application patch creates one origin-to-Root Document Update cascade. +- **C-UPD-02.** Presence Booleans preserve add/remove identity without null sentinels. +- **C-UPD-03.** Current update propagation continues on its frozen chain after source cut-off. +- **C-EVT-01.** Source Triggered handling precedes nearest-to-farthest ancestor Embedded handling. +- **C-EVT-02.** Events emitted during delivery are appended FIFO and do not interrupt the current occurrence. +- **C-EVT-03.** Child emissions are not returned unless Root explicitly emits. +- **C-EVT-04.** Duplicate equal event nodes remain distinct occurrences and Root outputs. +- **C-EVT-05.** The internal queue is drained exactly once by the normative owner. + +### 15.5 Checkpoints, lifecycle, and protected state + +- **C-CHK-01.** Checkpoint newness is evaluated before initialization. +- **C-CHK-02.** Absent checkpoint state is virtual and no empty marker is created for stale/rejected delivery. +- **C-CHK-03.** Checkpoint entries bind raw key, domain, and subject. +- **C-CHK-04.** Replacing a Channel at the same key changes the active checkpoint domain. +- **C-CHK-05.** Checkpoint write commits only after complete delivery and queue processing. +- **C-CHK-06.** Retry after uncertain commit is idempotent against authoritative Root. +- **C-CHK-07.** Removed channels and changed checkpoint domains are deterministically cleaned from processor checkpoint state without a Document Update. +- **C-LIFE-01.** Initiated lifecycle precedes initialized marker. +- **C-LIFE-02.** First termination request wins and lifecycle/marker occur at most once. +- **C-LIFE-03.** Scope replacement during lifecycle prevents marker write into replacement. +- **C-LIFE-04.** Gas failure during termination rolls back the entire invocation. +- **C-PROT-01.** Application patches cannot directly or indirectly alter protected state. +- **C-PROT-02.** Only the Process Embedded declaration fields `paths` and `collectionPaths` may change under their exact protected-state exception. + +### 15.6 Soundness, failure, indexability, and bounded loops + +- **C-SND-01.** Every changed ancestor to Root is type- and schema-validated. +- **C-SND-02.** Nearest-valid type generalization is deterministic and bounded by policy. +- **C-SND-03.** Generated type writes create Document Updates and are re-recognized. +- **C-SND-04.** Cyclic-set member mutation is rejected. +- **C-CYC-01.** A pure cyclic-set member is rejected as an independently mutable processing Root before provider demand. +- **C-CYC-02.** A pure cyclic-set member is rejected as a top-level processing event before provider demand. +- **C-CYC-03.** `Process Embedded` cannot terminate at or traverse through an opaque cyclic-member edge. +- **C-CYC-04.** An ordinary Root can preserve an untouched opaque cyclic-member edge while unrelated selected processing succeeds without opening it. +- **C-IDX-01.** A new Root with invalid embedded path, cycle, unsupported subscription extraction, or excess limit rolls back. +- **C-IDX-02.** Valid subscription delta is incremental and new intervals start after the current event. +- **C-FAIL-01.** Deterministic failure returns input Root, no events, and admitted gas. +- **C-FAIL-02.** Transient resource suspension commits no state, progress, events, or portable gas. +- **C-FAIL-03.** Gas exhaustion returns the canonical trace prefix and is deterministic on retry. +- **C-FAIL-04.** Compare-and-swap conflict commits nothing and is outside portable gas. +- **C-FAIL-05.** `PROCESS_ATTEMPT` may return `NeedsResources`, but no completed `ProcessResult` uses `needs-resources` as a status. +- **C-LOOP-01.** An internal event cycle is stopped by the shared gas limit and rolls back Root and Root events. + +### 15.7 Gas and executable-runtime integration + +- **C-GAS-01.** Every processor and semantic counter has an exact weight and microfixture. +- **C-GAS-02.** Charges are admitted before work and the failing charge is absent on exhaustion. +- **C-GAS-03.** Manifest opening and validation proof reuse follow run-local canonical memo rules. +- **C-GAS-04.** Text comparison, Integer limbs, and canonical sorting produce exact traces. +- **C-GAS-05.** Direct identity blocks charge only new/changed direct identity, never unchanged transitive content. +- **C-GAS-06.** Runtime child ledgers are live-bounded and merged exactly once. +- **C-GAS-07.** Executable-runtime representation state is unobservable and recursive boundary-size charging is absent. +- **C-GAS-08.** Provider verification and transport are outside portable gas. + +### 15.8 End-to-end results + +- **C-E2E-01.** A complete successful Root transition fixture asserts exact status, resulting document, Root event order, named trace, total gas, and semantic demands. +- **C-E2E-02.** A deep embedded delivery fixture asserts the same complete result dimensions and returns an empty public event sequence when Root emits nothing. +- **C-E2E-03.** An inline/reference representation matrix produces the exact same complete end-to-end result and trace. + +### 15.9 Machine-readable fixture package + +The implementation-baseline fixture package is bound to the exact runtime registry manifest and the exact `blue-contracts/gas/1.0` manifest. It publishes: + +- 96 executable behavior fixtures covering all 100 vectors in §§15.1–15.8; +- feeder/platform and revision-bound commit fixtures; +- locality semantic-demand assertions; +- 58 exact gas microfixtures and composite gas fixtures; +- a vector-to-fixture coverage map; +- a fixture schema and scripted runtime registry bindings; +- deterministic file digests and package identity. + +The fixture envelope is: + +```yaml +schema: blue-contracts-fixture/1.0 +id: +vectors: [C-...] +category: +operation: process | process-attempt | platform | gas-micro +input: + root: + event: + feeder: + provider: + runtime: +expected: + assertions: +``` + +`input.feeder.deliverySnapshot` is derived environment evidence. It is not caller-authored Blue content and is not a third semantic input to `PROCESS`. The harness independently verifies that it equals the canonical snapshot for the supplied Root revision, event, activation intervals, external-order policy, and runtime registry. + +The scripted fixture runtime is a conformance instrument, not a portable application runtime. Its control vocabulary and trace projections MUST be closed, versioned, and defined by the fixture schema and harness. Unknown control fields or projections fail closed. + +The implementation-baseline fixture-package identity is: + +```text +sha256:16392301655431695df6a7cc142a7e388e426c382bf4e3c5f06ddfafb8efecdc +``` + +The package contains 100 normative vectors, 96 behavior fixtures, and 58 gas fixtures. The behavior-fixture count is not required to equal the vector count because one executable fixture may cover several inseparable normative assertions. + +--- + +## 16. Worked Examples + +### 16.1 Lazy selected workflow + +```yaml +contracts: + buyerChannel: + type: Example External Channel + source: + blueId: + + approve: + type: Example Lazy Operation Handler + channel: buyerChannel + operation: approve + steps: + blueId: + + cancel: + type: Example Lazy Operation Handler + channel: buyerChannel + operation: cancel + steps: + blueId: +``` + +For an `approve` event, the processor recognizes every effective contract type and the relevant dispatch fields. It opens `` only after the approve Handler matches. `` remains collapsed. + +### 16.2 One deep external delivery + +```text +Root +├── unrelatedA +├── Emb1 +│ ├── unrelatedB +│ └── Emb2 +│ ├── unrelatedC +│ └── Emb3 +└── unrelatedD +``` + +The feeder index identifies one preselected Channel at `/Emb1/Emb2/Emb3`. The processor demands: + +```text +Root direct manifest +Emb1 direct manifest +Emb2 direct manifest +Emb3 direct manifest +required effective type/contract headers on that chain +selected Handler body and data it reads +changed nodes on the path back to Root +``` + +It does not semantically demand `unrelatedA`, `unrelatedB`, `unrelatedC`, or `unrelatedD` bodies. + +### 16.3 Root-only events + +Suppose: + +```text +Emb3 receives external X +Emb3 emits A +Emb2 observes A and emits B +Emb1 observes B and emits C +Root observes C, patches /status, and emits nothing +``` + +The successful result is: + +```text +ProcessResult.document = Root' +ProcessResult.events = [] +``` + +If Root explicitly emits `D`, the result is: + +```text +ProcessResult.events = [D] +``` + +### 16.4 Several selected scopes + +If the same event is preselected at: + +```text +/Emb1/Emb2/Emb3 +/Emb1/Emb2 +/Emb1 +/ +``` + +the external order is: + +```text +Emb3 -> Emb2 -> Emb1 -> Root +``` + +The complete Emb3 delivery, update cascades, and internal event propagation reach quiescence before Emb2 receives the original event. Root receives the original event last. One late failure rolls the complete Root transition back. + +### 16.5 Reference-backed patch + +Initial logical content: + +```yaml +x: + blueId: +``` + +where `X` directly contains: + +```yaml +a: 1 +archive: + blueId: +``` + +Patch: + +```yaml +op: replace +path: /x/a +val: 2 +``` + +The processor opens Root and `X`, preserves `` by BlueId, creates `X2`, rebuilds Root, and never demands the archive body. + +### 16.6 Active-scope cut-off + +A child Handler returns: + +```text +patch /child/value +patch /child/other +emit ChildCompleted +``` + +The first patch causes a Root Document Update Handler to replace `/child` as a whole. The old child occurrence is cut off. The replacement and already applied first patch/cascade remain tentative, but the old child's second patch, `ChildCompleted`, checkpoint, and later marker writes are discarded. + +An event that the old child had already emitted before replacement still continues through its frozen ancestor chain. + +### 16.7 Checkpoint domain + +Channel version A at key `buyer` processes event `E`: + +```text +entries.buyer.domain = domain(A) +entries.buyer.subject = E +``` + +A later Root replaces the effective channel contributions at `buyer` with semantically different version B. `domain(B) != domain(A)`, so B sees virtual empty checkpoint state. It does not accidentally inherit A's stale subject. + +### 16.8 New subscription frontier + +Event `A@100` adds a new external-source Channel while that source already contains `B@50`. + +The new interval begins strictly after `A@100`. `B@50` is not delivered retroactively. An initial Root admission that intends historical replay must declare a historical frontier explicitly. + +### 16.9 Deterministic order across independent sources + +Assume one Root subscribes to an identity-provider source and a bank source. Their concrete source-local keys are different, but the managed environment binds one global policy: + +```text +primary: provider-assigned microsecond time +secondary: stable source identity +tertiary: source-local entry order +``` + +The identity provider reports event `I` at time `100`, and the bank reports event `B` at time `99`. Even if `I` arrives first, the feeder waits for both completeness frontiers and processes: + +```text +B -> I +``` + +If both have primary time `100`, the policy's stable source-identity tie-breaker determines one order on every platform. Arrival order is irrelevant. The exact tuple above is illustrative; a concrete ecosystem publishes and identity-binds its own total-order policy under §3.6. + +### 16.10 Autonomous linked Root + +If two managed documents must observe one independently evolving object, that object is another managed Root: + +```text +SharedRoot processes and commits its own events. +RootA observes SharedRoot events later. +RootB observes SharedRoot events later. +``` + +It is not duplicated as one owned embedded occurrence that magically mutates under both parents. + +--- + +## Appendix A — Core Runtime Type Catalog + +The canonical runtime registry is the authority for exact source nodes and BlueIds. The definitions below state required semantics and intended identity-bearing fields. + +### A.1 Contract + +Base type for all runtime declarations under `contracts`. + +Required semantics: + +```text +order: optional Integer, default 0 +``` + +A concrete subtype declares one exact runtime role. + +### A.2 Channel + +Base Contract subtype that produces one channelized delivery or rejects an event. + +Processor-managed Channel subtypes receive only their processor event family.

Blue Language 1.0 is the first public-version Language specification and the normative implementation target for this package. Final public publication MUST bind this prose, the canonical core-type registry, published BlueIds, the machine-readable conformance fixtures, and implementation-conformance evidence in one content-addressed release manifest. + +> **Scope.** This document defines Blue's content language: the node model, Blue Graph, Blue Documents, typing, specialization through overlays, schema constraints, preprocessing, complete and demand-limited resolution, expansion, collapse, canonicalization, minimization, and BlueId. It defines the semantic equivalence of verified pure references and their materializations. It does **not** define runtime execution, handlers, events, channels, gas prices, provider transport, storage layout, or contract processing. Those belong to runtime specifications and implementations. + +Where this document references core types such as **Text**, **Integer**, **Double**, **Boolean**, **Dictionary**, and **List**, their canonical type definitions and canonical BlueIds are supplied by the canonical Blue type registry. Appendix A defines their normative semantics and shows the intended canonical registry nodes. The registry is the authority for the exact node content and BlueIds. + +Canonical core type nodes are identity-bearing Blue content. Their `description` fields define type semantics and affect BlueId. Editing a canonical description changes the type identity and therefore MUST be treated as a registry/versioning change, not as ordinary documentation editing. + +The complete Blue Language 1.0 conformance release is defined by this prose specification, the canonical Blue type registry, the Blue Language 1.0 conformance fixture package, and the content-addressed release manifest together. If these artifacts conflict, the release process MUST be corrected; implementations MUST NOT guess. + +## Conventions + +The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, **SHOULD NOT**, **MAY**, and **OPTIONAL** are to be interpreted as normative requirement levels. + +Sections marked **normative** define required behavior for conforming Blue Language 1.0 implementations. Sections marked **informative** explain intent, examples, or implementation guidance. + +--- + +## 0. Overview + +Blue Language describes reality as a **content-addressed graph of typed nodes**. Text, integers, doubles, booleans, lists, and dictionaries are the basic building blocks. Larger nodes are formed by connecting those smaller nodes. + +An informative mental model is to treat a Blue node as a perfectly defined word. A human-readable `name` helps people discuss the word, while its **BlueId** identifies one exact immutable meaning. The same exact node has the same BlueId wherever it appears, and a BlueId may stand in place of the node's complete verified explanation. + +This analogy does not replace the formal rules below. In particular, a BlueId is a content address, not merely a chosen label: changing identity-bearing content changes the BlueId. + +Blue has one BlueId format and one BlueId algorithm. An exact node may be identified directly. An authored Source Document first passes through preprocessing, complete resolution, and canonicalization; the BlueId of the resulting Canonical Identity Input is the BlueId derived from that Source Document. `Content BlueId` is a permitted shorthand for this derivation, not a second identifier kind. + +A **Blue Graph** is the conceptual network of Blue nodes. Nodes are connected by ordinary object fields, list elements, type links, and `blueId` references. A **Blue Document** is one serialized root and whatever part of that graph is currently materialized with it. It is **not required to contain the whole graph**. + +A node may therefore appear in either of these equivalent forms: + +```yaml +x: + a: 1 + b: 1 +``` + +```yaml +x: + blueId: +``` + +When the materialized node verifies to the referenced BlueId, these forms identify the same graph edge and the same Blue node. Inline versus referenced representation is not a semantic distinction. + +This equivalence is a load-bearing invariant. A semantic Blue operation MUST be a function of node identity and logical content demanded by that operation. It MUST NOT be a function of whether a node was inline, collapsed, already expanded, cached, fetched from one blob, fetched from many chunks, or represented internally by one host object or many. + +The Blue Language defines four ordinary graph operations: + +| Operation | Meaning | +|---|---| +| **Expand** | Replace selected pure references with verified materialized content. | +| **Collapse** | Replace selected verified materialized nodes with pure references to their BlueIds. | +| **Resolve** | Apply type inheritance, overlays, merge rules, fixed values, and schema rules. | +| **Minimize** | Produce a smaller Source overlay that resolves to the same semantic result. | + +Expansion and collapse change representation only. Resolution and minimization change how explicit or type-derived content is expressed. These operations act on ordinary Blue nodes; they do not create a second graph model. + +Expansion and resolution are independent dimensions. A processor may expand and resolve only the paths needed for its next decision while leaving unrelated branches collapsed. Limits are supplied out-of-band to the Language operation and do not become Blue content, affect BlueId, or change semantic meaning. + +Blue also permits **specialization through typing and overlays**. Specialization is not a fifth graph operation. To specialize a node is to create a new, more specific node that uses another node as its `type` and adds compatible overlay content. The specialized node is a new node and normally has a new BlueId. By contrast, expanding a node only reveals more of the same existing node and preserves its BlueId. + +A useful test is: + +```text +same node, more of it visible -> expand +new node, more specific meaning -> specialize +``` + +Blue content commonly appears in the following forms: + +| Form | Purpose | Identity status | +|---|---|---| +| **Source Document** | Authored input. May use authoring sugar and the root `blue` directive. | Not necessarily direct BlueId Input. | +| **Preprocessed Document** | Source after preprocessing has applied authoring transforms and removed `blue`. | Eligible for resolution and, if otherwise valid, direct hashing. | +| **Expanded or collapsed form** | The same node with more or fewer referenced descendants materialized. | Expansion and collapse preserve BlueId. | +| **Resolved Form** | Type-merged and schema-validated semantic content. It may be complete or explicitly limited to demanded paths. | Carries semantic meaning; not necessarily direct BlueId Input. | +| **Minimized Overlay** | A reduced author-facing overlay that resolves to the same complete Resolved Form. | Derives the same BlueId through the full Source Document identity pipeline. | +| **Canonical Identity Input** | The one deterministic identity form derived from a complete Resolved Form. | Direct input to the BlueId algorithm; its BlueId is the Source Document's BlueId. | + +Canonicalization is separate from minimization. Canonicalization produces the one deterministic BlueId input. Minimization produces a convenient smaller Source overlay and is not necessarily unique. **Minimization is not a step in Source Document BlueId calculation.** + +The two paths from a complete Resolved Form are: + +```text +Source Document + -- preprocess --> Preprocessed Document + -- fully resolve --> complete Resolved Form + | \ + | canonicalize \ minimize + v v + Canonical Identity Input Minimized Overlay + | | + BlueId algorithm ordinary Source form + | | + v `-- if processed again, + BlueId follows the full pipeline + to the same BlueId +``` + +A Source Document, Resolved Form, or Minimized Overlay MUST NOT be directly hashed and assumed to produce the Source Document's BlueId. Only the Canonical Identity Input has that guarantee. + +Ordinary processors do not need to run this entire pipeline merely to inspect or update a document. They may expand and resolve only demanded fields, preserve unchanged children by BlueId, and collapse the result again. + +List identity is deliberately incremental. If `P` is the established BlueId of an exact list prefix and `X` is the established BlueId of one appended element, the BlueId of the longer list is calculated by one domain-separated fold step over `P` and `X`. The earlier elements do not need to be materialized or rehashed merely to append. Replacing, inserting, or removing an earlier element is different: the fold suffix from the first changed position must be recomputed. The exact algorithm and worked example are in §14.7. + +A Blue Document is a rooted slice of a larger graph: + +```text +Selected document slice ++-----------------------------+ +| root | +| +- local field | +| +- local list | +| +- type: { blueId: T } -----+----> external type node T ++-----------------------------+ + \--> more graph reachable by BlueId +``` + +This specification defines content-language semantics only. + +--- + +## 1. Scope, Goals, Versioning, and Conformance + +### 1.1 Goal + +Blue is a universal, deterministic **content language** with: + +- a strict, mergeable type system with overlay and subtyping rules; +- a content address called **BlueId** that is stable across equivalent content forms; +- a precise pipeline that maps an authored document to deterministic content identity; +- graph-slice semantics, so documents can contain local content and external `blueId` references; +- identity-preserving expansion and collapse; +- complete or demand-limited resolution; +- semantics-preserving minimization; +- explicit operation outcomes in which unavailable or unexpanded content is never confused with semantic absence; +- local verification of a directly materialized node whose complete children remain represented by their exact BlueIds. + +### 1.2 Out of scope + +The following are not defined by this specification: + +- runtime execution; +- event processing; +- channels; +- handlers; +- gas accounting; +- document update listeners; +- processor lifecycle markers; +- contract execution. + +The field `contracts` is reserved by the language because it is a possible field in Blue content and therefore can affect BlueId. Its runtime meaning is defined only by the separate Blue Contracts and Processor Specification 1.0. + +### 1.3 Versioning and specification selection + +This document defines **Blue Language 1.0**, the first public-version Language specification. + +A Blue node does **not** carry a required `languageVersion`, `specification`, or similar field. Adding such a field would make version selection part of content identity and would create a bootstrapping problem: an implementation would need to interpret identity-bearing content before knowing which identity rules apply. The processing environment therefore selects Blue Language 1.0 out-of-band and MUST declare that selection before parsing identity-bearing content. + +The exact BlueIds of referenced types remain the normal way in which content selects type semantics. Runtime execution languages are selected by their exact runtime-type BlueIds under the applicable runtime specification; ordinary documents do not require a Language-version field. + +Blue Language 1.0 publishes the canonical nodes and BlueIds for `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` exactly as contained in the release registry. Those nodes have already been reproduced by multiple implementations and their identity-bearing descriptions intentionally name Blue Language 1.0. Implementations MUST load and verify the registry nodes rather than reconstructing them from prose or source-code constants. + +After publication, an existing core-type BlueId MUST never acquire different semantics. A semantic change requires a new type node and BlueId. Editorial clarification that is not intended to alter identity-bearing meaning belongs outside the canonical node. + +Blue Language 1.0 is intended to remain stable. Editorial changes that do not alter normative meaning may be published as errata outside canonical registry nodes. Any change that alters the node model, BlueId algorithm, preprocessing, resolution, canonicalization, minimization, or the meaning of valid 1.0 content requires a new Language version and an out-of-band version-selection rule known before the node is interpreted. + +A valid unprefixed plain BlueId always denotes the BlueId v1 algorithm defined by this specification. A future incompatible BlueId version MUST use syntax that is not valid as a plain BlueId v1; it MUST NOT reinterpret an existing valid v1 string. + +### 1.4 Conformance + +A conforming Blue Language 1.0 implementation MUST implement all normative requirements in this specification. + +A conforming implementation MUST support: + +- parsing Blue Source Documents and BlueId Input; +- preprocessing, including the standard baseline preprocessing environment; +- type resolution and overlay merging; +- schema validation; +- list merge semantics and list control forms; +- provider-backed resolution when referenced content is required; +- complete and demand-limited resolution with explicit complete, absent, incomplete, and invalid outcomes; +- representation-transparent graph access through verified pure references; +- expansion semantics, including provider-backed materialization when referenced content is required; +- the semantics of expansion, collapse, resolution, and minimization; an implementation need not expose each as one public method, but all corresponding behavior it exposes MUST follow this specification; +- canonicalization for Source Document BlueId calculation; +- author-facing minimization behavior sufficient to pass the conformance fixtures; +- direct BlueId calculation and Source Document BlueId calculation; +- circular reference set BlueIds; +- rejection of invalid Blue Language 1.0 documents and invalid BlueId Input; +- the Blue Language 1.0 conformance suite. + +An implementation MAY expose detailed demand enums, node handles, provider batches, storage indexes, work diagnostics, or caches. Those are implementation surfaces. They MUST preserve the semantic results required here and MUST NOT become observable Blue content. + +A library or tool that implements only a subset of this specification may be useful, but it MUST NOT describe itself as a conforming Blue Language 1.0 implementation. + +### 1.5 Core registry and release artifacts + +The canonical Blue type registry is part of the Blue Language 1.0 release surface. Its entries for `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` are content-addressed and versioned with this specification. + +A conforming implementation MUST use the published registry BlueIds for core type aliases. A different registry binding does not produce portable Blue Language 1.0 Source Document BlueId results. `Content BlueId` remains permitted shorthand for those results. + +Canonical registry nodes are self-describing Blue content. A registry node's `name` and `description` fields are identity-bearing. A concise normative `description` SHOULD define the type's semantics. Changing that semantic description changes the type BlueId and defines a different type. + +Non-normative examples, rationale, translations, tutorial material, implementation notes, and editorial commentary MUST NOT be included in canonical registry nodes unless intentionally made identity-bearing. Such material belongs in this prose specification or in separate documentation. + +The registry file is the authority for the exact parsed string content of canonical nodes. Code blocks in this specification that claim to show canonical nodes SHOULD be generated from, or kept Blue-equivalent to, the registry entries used to calculate the published BlueIds. + +The core-registry manifest MUST publish, for every entry: + +- registry kind and specification version; +- stable entry key; +- path of the canonical node file; +- the calculated BlueId; +- the SHA-256 digest of the exact node file; +- `semanticDescriptionIdentityBearing: true`; +- the Language fixture-package identity that verifies it. + +The manifest itself MUST publish one content-addressed package identity calculated by the release rule declared in that manifest. The top-level release manifest MUST bind that core-registry package identity. + +A complete Blue Language 1.0 conformance release consists of: + +1. this prose specification; +2. the canonical Blue 1.0 core-type registry and published BlueIds; +3. the machine-readable Blue Language 1.0 fixture package and its identity; +4. a content-addressed release manifest that binds the preceding artifacts. + +The release manifest MUST identify at least the specification revision, core-registry identity, fixture-package identity, and artifact digests. If the prose, registry, fixtures, or manifest conflict, the release is inconsistent and MUST be corrected. Implementations MUST NOT guess which artifact wins. + +Until all four artifacts exist and independent fixture execution has succeeded, this package remains an implementation baseline rather than a final public conformance release. + +--- + +## 2. Serialization and Data Model + +### 2.1 JSON data model (normative) + +Blue documents use the JSON data model: + +- objects; +- arrays; +- strings; +- numbers; +- booleans; +- null. + +YAML is an authoring syntax for this JSON data model. A YAML parser used for Blue MUST NOT introduce YAML-specific data types into the Blue data model. + +### 2.2 YAML restrictions (normative) + +When YAML is used for Blue serialization: + +- duplicate object keys MUST be rejected; +- custom YAML tags MUST be rejected; +- Portable Blue YAML MUST reject YAML anchors, aliases, and merge keys. An implementation MAY expose a non-portable preprocessing mode that expands them deterministically before Blue parsing, but documents relying on that mode are not portable Blue Source Documents. +- non-JSON implicit types, including timestamps, binary blobs, sets, and ordered maps, MUST be disabled; +- timestamp-like values SHOULD be quoted by authors. Blue Language 1.0 defines no timestamp scalar. + +Blue Language 1.0 YAML uses the YAML 1.2 JSON schema data model. Portable Blue YAML MUST reject custom tags, non-string object keys, binary tags, sets, ordered maps, and non-JSON implicit scalar types. + +The parsed value of a YAML block scalar is the exact Text value. Blue performs no block-scalar normalization. Different YAML scalar styles, indentation, folding, chomping indicators, trailing newlines, or line endings that produce different parsed strings produce different BlueIds. + +Examples: + +```yaml +# Text, not a Date/Time type in Blue Language 1.0 +ts: "2025-09-01T12:00:00Z" +``` + +Blue Language 1.0 does not define a core Date or Timestamp scalar type. + +### 2.3 Duplicate keys (normative) + +Serialized Blue documents MUST NOT contain duplicate object keys. Parsers MUST reject duplicate keys. Later-key-wins behavior is not conforming. + +### 2.4 Number tokens and large integers (normative) + +Blue distinguishes the mathematical value of an integer from the JSON/YAML encoding used to carry it. + +The interoperable **safe JSON numeric integer range** for Blue Language 1.0 is: + +```text +[-9007199254740991, 9007199254740991] +``` + +JSON itself does not define a numeric range. Blue uses this safe range because it is exactly representable by JSON implementations that store numbers as IEEE 754 binary64 values. + +Rules: + +1. An unquoted integer token within this range MAY be used as an `Integer` value. +2. An integer value outside this range MUST be authored as a quoted canonical decimal string and MUST have explicit type `Integer` or a type that resolves to `Integer`. +3. In Canonical Identity Input and BlueId Input, an `Integer` value outside this range MUST be represented as its quoted canonical decimal string while retaining the explicit `Integer` type. +4. The canonical decimal string form is an optional leading `-` followed by decimal digits, with no leading zeros except the single digit `0`. +5. Quoted decimal text without an explicit `Integer` type is Text, not Integer. + +A quoted canonical decimal string value is interpreted as an `Integer` when the node has an explicit effective type that resolves to `Integer`. The effective type may be authored locally or inherited from the resolved type chain. + +If no effective type resolves to `Integer`, quoted decimal text is Text. + +If an effective type resolves to `Integer` and the quoted value is not a valid canonical decimal integer string, resolution MUST fail. + +Primitive scalar inference for quoted strings is provisional for Source Documents. Resolution MUST refine a quoted scalar's effective scalar type to `Integer` when the inherited or explicit effective type resolves to `Integer` and the quoted value is a valid canonical decimal integer string. It MUST fail when that effective type requires `Integer` and the quoted value is not canonical Integer text. + +Examples: + +```yaml +small: + type: Integer + value: 42 + +large: + type: Integer + value: "9007199254740992" +``` + +The same rule applies below the negative bound: + +```yaml +veryNegative: + type: Integer + value: "-9007199254740992" +``` + +Example with inherited Integer type: + +```yaml +# Type +name: Account +accountId: + type: Integer + +# Source instance +type: Account +accountId: "9007199254740992" +``` + +After preprocessing and resolution, `accountId` is an Integer value because the effective inherited type resolves to `Integer`. + +Without the inherited or explicit Integer type, the same quoted value is Text. + +Floating-point `Double` values MUST be finite. `NaN`, `Infinity`, and `-Infinity` are not valid Blue scalar values. + +Double parsing MUST produce a finite IEEE 754 binary64 value using round-to-nearest, ties-to-even semantics. A numeric token that overflows to positive or negative Infinity, underflows to a non-finite value, or parses as NaN is invalid. + +A parsed `-0.0` Double value compares equal to `0.0` and canonicalizes as JSON number `0` under RFC 8785. The node remains Double because its effective type is Double. + +A Double whose RFC 8785 canonical JSON representation is integer-looking, such as `1`, remains Double because its effective type is represented in BlueId Input. + +If a parser cannot deterministically parse a numeric token as binary64 with these semantics, the implementation MUST reject the token or require explicit authoring in a supported form. + +### 2.5 Numeric token inference (normative) + +When a numeric Source Document value has no explicit type: + +- an unquoted integer token with no decimal point and no exponent infers `Integer`; +- an unquoted numeric token with a decimal point or exponent infers `Double`, even if its mathematical value is integral. + +Examples: + +```yaml +a: 1 # Integer +b: 1.0 # Double, canonical numeric payload may render as 1 +c: -0.0 # Double, canonical numeric payload renders as 0 +d: 1e999 # invalid Double +``` + +If a parser cannot preserve the lexical distinction between integer tokens and decimal/exponent tokens, it MUST require explicit type annotations for ambiguous numeric values or document that such inputs are not portable Source Documents. + +### 2.6 String and multiline scalar identity (normative) + +After parsing, a Blue string value is identity-bearing exactly as parsed. Blue Language performs no automatic whitespace normalization, line-ending normalization, trailing newline stripping, indentation rewriting, Unicode normalization, case folding, or YAML block-scalar canonicalization. + +Different YAML scalar styles may produce different string values and therefore different BlueIds. In particular, YAML block scalar choices such as `|`, `|-`, `|+`, `>`, and `>-` may differ in line folding and trailing newline behavior. + +Canonical registry nodes SHOULD be generated, fixture-checked, or otherwise protected against accidental string drift. Authors of identity-sensitive documents SHOULD treat edits to multiline `description` fields as content edits, not formatting edits. + +Blue Language uses the parsed Unicode code-point sequence. Implementations MUST NOT normalize Text by default. Applications that need a normalization convention, such as NFC, SHOULD apply it explicitly at the application/preprocessing layer. + +--- + +## 3. Blue Graph, Blue Documents, and References + +### 3.1 The Blue Graph (normative) + +The **Blue Graph** is the conceptual content-addressed network of Blue nodes. Edges in the graph arise from: + +- ordinary object fields, for example `address -> child node`; +- list elements; +- type links, for example `type: ...`; +- `blueId` references. + +Nodes are identified by BlueId. The graph is global and content-addressed; it is not owned by any single document. + +### 3.2 Blue Documents as graph slices (normative) + +A **Blue Document** is a serialized rooted slice of the Blue Graph. It may contain: + +- fully materialized child nodes; +- pure references to external nodes using `{ blueId: ... }`; +- a mixture of local content and external references. + +A Blue Document is not required to be closed. A `{ blueId: X }` reference may point to content outside the selected document. Implementations use a provider only when an operation demands referenced content. + +A materialized child whose BlueId is `X` and a pure `{ blueId: X }` reference are representation-equivalent. Language operations, validators, and higher-level processors MUST NOT assign different semantic meaning merely because one form is expanded and the other is collapsed. + +This equivalence also permits one exact configuration node to be reused in many larger documents. For example, a runtime Channel or participant-binding node may be written inline in one document and as `{ blueId: X }` in another. Blue Language treats both as the same exact node. Whether a runtime gives that node executable meaning is outside this specification; Blue Language itself does not create live aliases to unrelated parent or ancestor fields. + +### 3.3 Pure references (normative) + +A **pure reference** is exactly: + +```yaml +blueId: +``` + +or, as a field value: + +```yaml +field: + blueId: +``` + +A pure reference object MUST NOT carry sibling fields. The following is not a pure reference: + +```yaml +blueId: +name: Something +foo: bar +``` + +Mixed `blueId` forms MUST be rejected in Source Documents, Preprocessed Documents, Canonical Identity Input, and BlueId Input. Provider metadata MUST be represented out-of-band or in a non-Blue envelope. + +A non-Blue envelope is packaging metadata outside the Blue Document root. It is not part of the Blue node and is not included in BlueId calculation. + +A pure reference cannot carry sibling fields. To specialize referenced content, the reference MUST appear in a type position or be resolved as an ancestor/type, and the overlay MUST be written as ordinary instance content outside the pure reference object. + +Invalid: + +```yaml +blueId: X +extra: value +``` + +Valid as a typed overlay: + +```yaml +type: + blueId: X +extra: value +``` + +### 3.4 Document identity (normative) + +The BlueId of a Blue Document is the BlueId of its root node. There is no separate document-level identity above the root node. + +A Blue Document root MAY be a scalar, list, object, or pure reference. Scalar and list roots follow the same wrapper-equivalence rules as field values. A Blue Document root MUST NOT be `null`. + +--- + +### 3.5 Exact-node equivalence and materialization state (normative) + +Let `X` be a valid BlueId. A pure reference: + +```yaml +blueId: X +``` + +and any verified materialization whose BlueId is `X` denote the same exact Blue node. + +For semantic Blue operations, materialization state is out-of-band. It MUST NOT change: + +- node kind; +- field or list membership; +- equality or matching; +- effective type or schema; +- presence or absence; +- any semantic conclusion once the same logically required evidence is available; +- BlueId. + +A serialization-inspection API MAY expose that a supplied syntax object contains the key `blueId`. A semantic graph API MUST NOT expose the pure-reference wrapper as an ordinary child field of the referenced node. For example, if `/x` denotes node `X`, a semantic lookup of `/x/blueId` does not succeed merely because `/x` was supplied in collapsed form. Exact identity is obtained through an explicit node-identity operation. + +Expansion state, provider location, cache state, and storage segmentation are not Blue content and MUST NOT be inserted into a Blue node. + +### 3.6 Identity-preserving implementation values (normative behavior) + +An implementation MAY represent an exact node internally by a handle containing its BlueId, optional verified materialization, and out-of-band provider or coverage information. No particular handle class or public API is required. + +Whenever an implementation passes, snapshots, emits, stores, or returns an already verified node, it MUST preserve the exact BlueId and MUST NOT require recursive cloning or transitive materialization merely to carry that value. + +Portable application semantics MUST NOT depend on whether such an implementation value currently carries materialized content. When an operation demands unavailable content, the operation returns an incomplete or provider outcome under §§10 and 12 rather than inventing semantic absence. + +## 4. Node Model and Reserved Fields + +### 4.1 Node anatomy (normative) + +A **Blue node** consists of reserved language fields and, optionally, one primary payload kind. + +```text +Node = reserved language fields + zero or one payload kind +``` + +The permitted payload kinds are: + +- **scalar payload**: a `value` field carrying a string, number, or boolean; +- **list payload**: an `items` field carrying an ordered sequence; +- **object payload**: one or more ordinary child fields, where ordinary child fields are fields whose keys are not reserved language keys. + +A node MUST NOT combine payload kinds. For example, a node MUST NOT contain both `value` and `items`, or both `value` and ordinary child fields. + +A node MAY have no payload. Such a node is a metadata-only, type-only, schema-only, or overlay-only node. Examples include: + +```yaml +age: + type: Integer +``` + +and: + +```yaml +name: Person +``` + +A pure reference is a special metadata-only reference node. It is valid only when the object contains exactly `blueId`. + +If a node has no payload and no retained reserved content after object-field cleaning, it may normalize to an empty map and be omitted when it appears as an object field. It MUST NOT be silently deleted when it appears as a list element; list element normalization is context-sensitive (§11.5, §14.2). + +### 4.1.1 Unconstrained field declarations (normative) + +A declaration-only child with no effective `type`, fixed payload, payload-kind constraint, or applicable schema constraint does not constrain the kind or type of a later value at that path. + +For example: + +```yaml +request: + description: > + Optional application-defined request payload. +``` + +means that `request`, when present, may contain any valid Blue node: a scalar, list, object, specialized node, or pure reference. It remains optional unless its effective schema contains `required: true`. + +A required but otherwise unconstrained field is written as: + +```yaml +request: + description: > + Required application-defined request payload. + schema: + required: true +``` + +Omitting `type` is the ordinary way to express "no type constraint." By contrast: + +```yaml +request: + type: Dictionary +``` + +constrains the field to the canonical Dictionary type or a compatible specialization. It does **not** mean "any Blue value." Likewise, `type: List` constrains the value to a List even when `itemType` is omitted. + +A meaningful `name` or `description` may retain and document an unconstrained declaration. An empty declaration `{}` may be removed by object-field cleaning and therefore is not a reliable declaration marker. + +### 4.2 Reserved language keys (normative) + +The following keys are reserved by the language: + +```text +name, description, +type, itemType, keyType, valueType, +value, items, +blueId, blue, +schema, mergePolicy, +contracts +``` + +The following keys are reserved-invalid and MUST be rejected wherever they would appear as object fields: + +```text +properties, constraints +``` + +Reserved fields are grouped as follows: + +| Category | Fields | +|---|---| +| Identity labels | `name`, `description` | +| Type and constraint metadata | `type`, `itemType`, `keyType`, `valueType`, `schema`, `mergePolicy` | +| Payload wrappers | `value`, `items` | +| Reference and preprocessing controls | `blueId`, `blue` | +| Reserved extension field | `contracts` | + +`contracts` is reserved by the language but semantically defined only by the Blue Contracts and Processor Specification 1.0. + +The key `blue` is valid only as a preprocessing directive on the root of a Source Document. A conforming implementation MUST reject `blue` anywhere else. Direct BlueId calculation MUST reject any node containing `blue` as direct BlueId Input. + +There is no `properties` field in the Blue Language. The key `properties` is reserved-invalid in Blue Language 1.0 and MUST NOT appear as an ordinary child field or language wrapper. Applications that need a data key literally named `properties` MUST use an escaped representation defined by the application's type. + +Reserved language keys cannot be used as ordinary child-field names in direct object encoding. Direct object encoding can therefore represent only data keys that do not collide with reserved language keys. +Applications that need arbitrary user keys, including keys that equal reserved language keys, MUST use an escaped representation defined by the application's type. + +### 4.3 Reserved field value types (normative) + +Implementations MUST validate reserved field value types. + +| Field | Required value shape | +|---|---| +| `name` | string, or absent | +| `description` | string, or absent | +| `type` | node, string alias in Source Documents before preprocessing, or pure reference | +| `itemType` | node, string alias in Source Documents before preprocessing, or pure reference | +| `keyType` | node, string alias in Source Documents before preprocessing, or pure reference | +| `valueType` | node, string alias in Source Documents before preprocessing, or pure reference | +| `value` | string, number, boolean, or absent | +| `items` | list, or absent | +| `blueId` | string BlueId, only in pure references | +| `blue` | root Source Document only; string directive alias, inline preprocessing-directive node, or pure reference to one | +| `schema` | object using only schema keywords from §9, pure reference to such an object, or absent | +| `mergePolicy` | `append-only`, `positional`, or absent | +| `contracts` | object, pure reference to such an object, or absent; runtime semantics out of scope | + +Wrong reserved-field types MUST be rejected. Implementations MUST NOT silently coerce reserved field values such as `blueId: 123` or `name: true` into strings. A pure reference accepted for `schema` or `contracts` MUST be expanded when the operation needs to validate or interpret the referenced object's contents; its collapsed form is not an exemption from the field's semantic shape rules. + +### 4.4 `contracts` boundary (normative) + +In Blue Language 1.0, `contracts` is a reserved identity-bearing content field. A language implementation MUST parse, preserve, resolve, canonicalize, and hash `contracts` as content. It MUST NOT execute `contracts`. + +Unless a separate processor specification is explicitly being applied, `contracts` participates in language-level merge and canonicalization according to ordinary object-field rules. Runtime interpretation, reserved processor keys under `contracts`, processor lifecycle behavior, and contract capability handling are outside this specification. + +When a `contracts` value is a pure reference and an operation needs to merge or inspect that map, the reference MUST be expanded and verified first. Language-level merge of the resulting `contracts` maps is field-wise: + +- If only the ancestor contributes a contract entry at key `k`, the entry is materialized in the Resolved Form as type-derived content. +- If only the instance contributes a contract entry at key `k`, the entry is preserved as instance-supplied content. +- If both ancestor and instance contribute `contracts[k]`, the two contract nodes are merged recursively under the same fixed-value, type-compatibility, schema, and object-field rules used for ordinary child fields. +- A descendant MUST NOT remove an inherited contract entry during language resolution. Runtime removal or mutation of contracts, if allowed, belongs to the Blue Contracts and Processor Specification 1.0. +- The language resolver MUST NOT interpret, execute, sort, dispatch, or validate processor-specific contract behavior. + +Processor-reserved keys inside `contracts` have no runtime effect in this specification. They are still parsed, resolved, canonicalized, and hashed as content. + +### 4.5 `name` and `description`: identity vs field semantics (normative) + +`name` and `description` are content on the node. They affect BlueId. + +They are also matcher-neutral. Matchers MUST ignore `name` and `description` for: + +- type conformance checks; +- subtype compatibility checks; +- structural or shape matching; +- resolution matching. + +Identity equality includes `name` and `description`. Structural and type equality ignore them. + +### 4.6 Document identity vs field semantics for labels (normative) + +A node whose `type` is `T` is not `T`; it is a new entity. The resolved node's top-level `name` and `description` come only from the instance and MUST NOT be inherited from the type. The embedded type object may carry its own `name` and `description` inside `node.type`. + +When a type materializes declaration-only fields or list elements into an instance, those child nodes carry the type's `name` and `description` as inherited labels until the instance explicitly overrides them. + +However, when the inherited child node contains a fixed payload value, fixed list payload, fixed object subtree, or pure reference, the labels on that node are part of the inherited fixed value's identity. A descendant MUST NOT change `name` or `description` on such a fixed-value node unless the inherited type leaves that label absent or the change is otherwise allowed by an explicit resolution rule. + +Dereferencing `{ blueId: X }` to materialize a node may copy the referenced node's `name` and `description` onto that materialized node, because the node itself is being materialized. This is expansion, not type inheritance. + +--- + +## 5. Authoring Forms and Wrapper Equivalence + +### 5.1 Wrapper equivalence (normative) + +To improve ergonomics, Blue admits equivalent authoring forms for scalars and lists, provided the wrapper has no other keys. + +Scalar sugar: + +```yaml +x: 1 +``` + +is equivalent to the wrapped form: + +```yaml +x: + value: 1 +``` + +List sugar: + +```yaml +x: [a, b] +``` + +is equivalent to: + +```yaml +x: + items: [a, b] +``` + +### 5.2 Sugar vs explicit metadata (normative) + +The sugar rule applies only when the wrapper has no other keys. Therefore: + +```yaml +x: 1 +``` + +is sugar for: + +```yaml +x: + value: 1 +``` + +but: + +```yaml +x: + type: Integer + value: 1 +``` + +is not sugar. It is the explicit scalar node form with metadata. + +A node may carry metadata such as `type`, `description`, `schema`, or `mergePolicy` alongside a payload kind. Metadata is not a payload kind. + +### 5.3 Object nodes (normative) + +Object payloads are written directly as ordinary child fields: + +```yaml +x: + a: 1 + b: 2 +``` + +There is no `properties` wrapper. The key `properties` is reserved-invalid (§4.2). + +### 5.4 Identity over forms (normative) + +Equivalent authoring forms of the same semantic content MUST derive the same BlueId through the Source Document identity pipeline. + +The BlueId algorithm operates on the abstract node model after canonical input normalization, not on authoring syntax. In particular, a bare scalar and its `{ value: ... }` wrapped form normalize identically. A bare list and its `{ items: ... }` wrapped form normalize identically. + +--- + +## 6. Preprocessing and the `blue` Directive + +### 6.1 Purpose and governing model (normative) + +Every Blue Source Document is processed by the standard preprocessing algorithm defined by this specification. The absence of a root `blue` directive means that the document supplies no document-specific preprocessing configuration; it does **not** disable standard preprocessing. + +The standard preprocessing algorithm is part of Blue Language 1.0. It is not represented by an implicit, injected, or hidden `blue` directive. + +The root of a Source Document MAY contain a `blue` field. The optional `blue` directive supplements standard preprocessing with: + +- document-local type aliases declared through `imports`; and +- an ordered list of explicitly identified source transformations declared through `transformations`. + +The `blue` directive cannot replace, reorder, or disable mandatory baseline preprocessing. + +Preprocessing is part of Source Document BlueId calculation. It is not part of direct BlueId calculation, because direct BlueId accepts only BlueId Input. + +The portable value of `blue` is either: + +1. an inline preprocessing-directive node; or +2. a pure reference to an exact preprocessing-directive node: + +```yaml +blue: + blueId: +``` + +An inline directive and a verified materialization of a referenced directive are equivalent. The directive may therefore be expanded or collapsed like any other exact Blue node. Expansion or collapse of the directive MUST NOT change the preprocessed result. + +A pure reference under `blue` MUST remain a pure reference. It cannot carry sibling fields. To combine or change a referenced directive, an author creates another exact directive node containing the desired combined imports and transformations, and may then reference that new node by BlueId. + +A string-valued `blue` MAY be supported as authoring shorthand for an implementation-configured directive alias: + +```yaml +blue: Ticket Details v1.51 +``` + +The alias MUST resolve to one exact preprocessing-directive BlueId before preprocessing begins. An unbound alias fails deterministically. A Source Document that depends on a string alias has a portable Source-derived BlueId only when the exact alias-to-BlueId binding is itself identity-bound by the declared preprocessing environment or release artifact. The portable self-contained form is the pure reference form. + +Raw URL fetching is not a portable meaning of a string-valued `blue`. A URL MAY be used by a provider as a transport location for an expected BlueId, but unverified URL content MUST NOT define preprocessing semantics. + +### 6.2 Portable preprocessing-directive node (normative) + +A portable materialized preprocessing-directive node MAY contain the following directive fields: + +```text +imports +transformations +``` + +It MAY also contain ordinary identity-bearing node metadata such as `name`, `description`, and an exact `type` reference. Such metadata identifies the directive node itself but does not become content of the preprocessed Source Document. + +The `imports` field, when present, MUST be either: + +- an object mapping aliases to pure references; or +- a pure reference to such an object. + +The `transformations` field, when present, MUST be either: + +- a list of transformation nodes; or +- a pure reference to such a list. + +Each transformation list item MAY be materialized inline or represented by a pure reference. Every referenced directive, imports object, transformations list, or transformation node required by preprocessing MUST be fetched through the configured provider and verified against its requested BlueId before use. + +A preprocessing-directive node MUST NOT itself contain a `blue` directive. Blue Language 1.0 does not define recursive directive composition or a separate `profile` field. Reuse is achieved by placing the complete directive in an exact node and using: + +```yaml +blue: + blueId: +``` + +Unknown directive fields are not portable. A conforming strict implementation MUST reject an unknown directive field unless an exact separately published preprocessing extension defines that field, its ordering, its identity, and its conformance behavior. + +### 6.3 Imports (normative) + +A conforming implementation MUST support this portable shape: + +```yaml +blue: + imports: + AliasName: + blueId: +``` + +Each key under `imports` is an authoring alias. Each value MUST be a pure reference to a plain BlueId. Cyclic-member identities and algorithm-internal placeholders are not valid import targets in Blue Language 1.0. + +The effective import map consists of: + +1. the canonical built-in core aliases supplied by the Blue Language 1.0 core registry; and +2. the aliases declared by the effective preprocessing directive. + +An alias name MUST NOT be declared more than once in the effective imports object. A directive import MUST NOT redefine a built-in core alias unless it maps to the same canonical BlueId. + +Imports are scoped to the Source Document being preprocessed. Automatic alias substitution applies only in these type-bearing positions: + +```text +type +itemType +keyType +valueType +``` + +The same Text value in an ordinary data field is not replaced merely because it equals an alias name. + +The effective import map is established and verified before transformation execution, but automatic alias substitution is performed only during mandatory baseline preprocessing **after all declared transformations have completed**. This permits a transformation to emit a type alias that is then resolved by the document's imports. + +An imported alias that is not used does not affect the resulting Preprocessed Document or its Source-derived BlueId. + +### 6.4 Transformations (normative) + +The portable transformation list has this shape: + +```yaml +blue: + transformations: + - type: + blueId: + # transformation-specific configuration +``` + +A transformation node MUST have an exact effective transformation type that can be established without applying the Source Document's aliases or transformations. In the portable form, the transformation's `type` is a pure BlueId reference, or the transformation item is itself a pure reference to a verified node whose transformation type can be established from exact content. + +The exact transformation type BlueId selects the deterministic transformation implementation. Human-readable `name` values do not select transformation semantics. + +A required transformation whose type is unsupported MUST cause deterministic preprocessing failure. An implementation MUST NOT ignore, approximate, reorder, or substitute a required transformation. + +Declared transformations execute under these rules: + +1. the list order is semantic; +2. each transformation is applied exactly once; +3. transformation `i + 1` receives the complete output of transformation `i`; +4. the first transformation receives the parsed Source Document with the root `blue` field removed; +5. transformations run before mandatory baseline preprocessing; +6. automatic import substitution and primitive inference have not yet been applied when a transformation begins; +7. a transformation MAY consult the already established effective import map when its exact transformation specification defines such access, but this does not itself perform alias substitution; +8. a transformation MUST NOT introduce a `blue` field at any path; +9. a transformation's output may use ordinary Source syntax, wrapper sugar, imported aliases, bare primitive values, and list placeholders; mandatory baseline preprocessing normalizes that output afterward. + +The transformation list is not repeatedly evaluated and is not applied until reaching a fixed point. + +A portable transformation type MUST define, through its exact published semantics and fixtures: + +- accepted input and configuration shape; +- exact deterministic output rules; +- collision and duplicate-key behavior; +- Unicode, locale, date/time, and numeric behavior where applicable; +- error behavior; +- resource limits or a deterministic bound; +- whether and how the effective import map is available; +- conformance fixtures. + +Transformations MUST be pure and deterministic. They MUST NOT depend on ambient time, randomness, locale, time zone, environment variables, local files, unverified network content, mutable databases, cache state, thread scheduling, or any other hidden state. + +### 6.5 Exact preprocessing order (normative) + +A conforming implementation MUST produce the result defined by the following conceptual algorithm. Implementations MAY fuse or optimize stages only when the observable result and deterministic failures remain identical. + +#### Stage 1 — Parse the Source Document + +Parse JSON or portable YAML under §§2.1–2.3. Preserve the root `blue` value for directive processing. Reject duplicate keys and invalid Blue source syntax. + +#### Stage 2 — Establish the effective directive without mutating the Source Document + +1. If `blue` is absent, use an empty document-specific directive. +2. If `blue` is a string, resolve it through the declared directive-alias binding to one exact BlueId. +3. If `blue` is a pure reference, fetch and verify the referenced preprocessing-directive node. +4. If `blue` is inline, validate it as a preprocessing-directive node. +5. Materialize and verify any referenced `imports`, `transformations`, and transformation items required by the directive. +6. Build and validate the effective import map. +7. Resolve every transformation to a supported exact transformation implementation. +8. Freeze the ordered transformation list. + +If this stage cannot complete, preprocessing fails before any transformation executes. + +#### Stage 3 — Remove `blue` + +Create the working Source Document by removing the root `blue` field. The directive is not passed as ordinary document content to transformations. + +#### Stage 4 — Execute declared transformations + +Apply the frozen transformations exactly once each, in declared list order. Each transformation consumes the prior working result and produces the next working Source Document. + +If any transformation fails, produces invalid Source structure, introduces `blue`, exceeds its deterministic limit, or requires unavailable/invalid evidence, preprocessing fails. No partially transformed document is a successful result. + +#### Stage 5 — Apply mandatory baseline preprocessing + +Apply the following baseline operations to the transformed Source Document in this order: + +1. **Wrapper normalization.** Normalize scalar and list authoring sugar into the abstract Blue node model (§5). +2. **List placeholder normalization.** Normalize Source list elements that are `null`, `{}`, or recursively clean to an empty object into `$empty: true` (§11.5). +3. **Type-alias substitution.** Replace built-in and document-import aliases in `type`, `itemType`, `keyType`, and `valueType` positions with their canonical pure references. +4. **Primitive scalar inference.** Assign `Text`, `Integer`, `Double`, or `Boolean` to untyped primitive scalar payloads under §§2.4–2.5 and §14.3. +5. **Preprocessed-form validation.** Reject unresolved authoring aliases in type-bearing positions, nested or transformation-introduced `blue`, invalid payload combinations, malformed list controls, and any other invalid Preprocessed Document content. + +This ordering is normative. In particular: + +- transformations see the source before automatic import substitution and primitive inference; +- a transformation may emit `type: Person`, after which the `Person` import is substituted in Stage 5; +- a transformation may emit `count: 7`, after which Integer inference occurs in Stage 5; +- a transformation that replaces an alias with an exact pure reference prevents later import substitution at that position because no alias remains there. + +Applying preprocessing to an already valid Preprocessed Document that contains no `blue`, no unresolved aliases, and no Source-only placeholder forms MUST be idempotent. + +### 6.6 Identity and provenance (normative/informative) + +The `blue` directive is preprocessing configuration, not semantic content of the resulting document. Successful preprocessing removes it completely. + +Therefore: + +- an inline directive and the same directive supplied as `{ blueId: X }` produce the same result; +- different directive nodes may produce the same Preprocessed Document and Source-derived BlueId; +- different alias names that resolve to the same exact type may produce the same Source-derived BlueId; +- unused imports do not affect the Source-derived BlueId; +- source language, field spelling before a rename transformation, and preprocessing configuration are not recoverable from the Source-derived BlueId alone. + +Systems that require authoring provenance SHOULD retain an out-of-band preprocessing receipt containing, as applicable: + +```text +source artifact identity +Blue Language release identity +directive BlueId or alias binding identity +ordered transformation node identities +effective imports identity +preprocessed result BlueId +final Source-derived BlueId +diagnostics +``` + +The receipt is not part of the resulting Blue document unless an application explicitly stores it as content. + +### 6.7 Security and acquisition (normative) + +Remote acquisition of directive and transformation nodes is disabled by default unless the host explicitly configures a provider capable of obtaining exact BlueIds. + +Any directive, imports object, transformations list, transformation node, or transformation dependency fetched by BlueId MUST verify against that BlueId before use. Verification failure causes deterministic preprocessing failure. + +An implementation-local directive alias MUST resolve to one exact BlueId. It MUST NOT resolve directly to mutable or unverified content. + +A provider MAY use HTTP, a database, a filesystem, or another transport internally, but transport location is not preprocessing meaning. The requested BlueId and verified returned content define the acquired node. + +Implementations MUST impose deterministic hosted bounds on preprocessing, including suitable limits for transformation count, directive graph depth, referenced preprocessing resources, input/output node count, and text processed. Exceeding a bound causes preprocessing failure and MUST NOT return a partial successful document. + +### 6.8 General preprocessing rules (normative) + +- The `blue` directive is valid only on the root of a Source Document. +- A nested `blue` field is invalid. +- The `blue` directive is not semantic content of the resulting document. +- A document containing `blue` is not valid direct BlueId Input. +- Preprocessing MUST remove `blue` before resolution, canonicalization, or Source Document BlueId hashing. +- Direct BlueId calculation MUST reject a node containing `blue`. +- Simply ignoring `blue` is not conforming. +- Unsupported required transformations fail deterministically. +- Missing directive or transformation evidence is not treated as an empty directive. + +--- + +## 7. BlueId: One Identifier, Two Calculation Paths + +### 7.1 One BlueId (normative) + +Blue defines one identifier format and one identity algorithm: **BlueId**. + +Every valid exact Blue node has one BlueId. That BlueId identifies the node's exact immutable content. A pure reference: + +```yaml +blueId: X +``` + +always denotes the exact Blue node whose BlueId is `X`. It does not denote an authoring alias, a family of equivalent Source Documents, or an implementation-selected representation. + +A human-readable `name` may help people discuss a node, but only the BlueId identifies its exact content. Expansion and collapse preserve BlueId because they reveal or hide verified materialization of the same node. + +Blue does **not** define separate `NodeBlueId`, `SemanticBlueId`, or `MeaningId` identifier kinds. The phrases **direct BlueId calculation** and **Source Document BlueId calculation** describe two ways to derive an ordinary BlueId; they do not define different result formats or namespaces. + +This section defines the relationship conceptually. The exact BlueId v1 algorithm is specified in §14. + +### 7.2 Two calculation paths (normative) + +#### Direct BlueId calculation + +Direct calculation applies the BlueId algorithm to valid **BlueId Input**: + +```text +valid exact Blue node + -> BlueId input normalization + -> BlueId algorithm + -> BlueId +``` + +This is the normal identity path for exact graph nodes, provider verification, pure references, document revisions, type definitions, workflow bodies, event nodes, list prefixes, and every immutable fragment. + +#### Source Document BlueId calculation + +A Source Document may contain authoring sugar, a root `blue` directive, type aliases, overlays, or list controls. Its identity is therefore derived through the complete Source pipeline: + +```text +Source Document + -> preprocess + -> complete resolution + -> canonicalization + -> Canonical Identity Input + -> direct BlueId calculation + -> BlueId +``` + +The resulting value is an ordinary BlueId: the BlueId of the unique Canonical Identity Input. This specification also uses **Source-derived BlueId** as descriptive prose for that result; it does not name a different identifier type. + +The term **Content BlueId** MAY be used as shorthand for "the BlueId derived from this Source Document through the complete identity pipeline." It describes the relationship between a Source Document and a BlueId. It is not a second kind of BlueId. + +All conforming implementations MUST derive the same BlueId for equivalent Source Documents under the same Blue Language release and canonical registry bindings, provided every demanded reference resolves to the same verified node. Provider location, cache contents, lookup order, batching, and other ambient provider state are not identity inputs. + +### 7.2.1 What the Source-derived BlueId identifies (normative) + +The Source-derived BlueId identifies the exact Canonical Identity Input, not the original authoring syntax. + +For example, these Source Documents may derive the same BlueId: + +```yaml +blue: + imports: + Person: + blueId: + +type: Person +name: Alice +``` + +```yaml +type: + blueId: +name: Alice +``` + +Their aliases and preprocessing configuration differ, but their Canonical Identity Input is the same exact node. + +Consequently, a pure reference containing that BlueId refers to the canonical exact node. It does not preserve which alias, transformation spelling, YAML formatting, or Minimized Overlay was originally authored. A system that must preserve authoring provenance SHOULD retain a separate source artifact hash or preprocessing receipt. + +A Source Document provider MAY return authored Source content only under the explicit provider mode defined in §12.3. That mode verifies the Source-derived BlueId by running the complete pipeline. It does not change the meaning of `{ blueId: X }`, which still identifies one exact node `X`. + +### 7.2.2 Intermediate forms and direct hashing (normative) + +The following forms may all participate in expressing the same content: + +```text +Source Document +Preprocessed Document +Resolved Form +Minimized Overlay +Canonical Identity Input +``` + +They are not interchangeable as direct BlueId inputs. + +- A Source Document may contain `blue`, aliases, or Source-only controls and therefore may not be valid BlueId Input. +- A Resolved Form may contain inherited materialized content that canonicalization will omit as derivable. +- A Minimized Overlay is Source form and may contain `$previous`, `$pos`, `$replace`, or optional collapse choices. +- A Canonical Identity Input is the unique exact node whose direct BlueId is the Source Document's BlueId. + +A conforming implementation MUST NOT directly hash a Source Document, Resolved Form, or Minimized Overlay and describe that result as the Source Document's BlueId unless the form has first been proven identical to the Canonical Identity Input. + +### 7.3 Identity preservation across forms (normative) + +Expansion preserves BlueId when the provider returns verified content. Pure references contribute their target BlueIds; materializing a reference does not change the surrounding node's BlueId when the materialized content verifies to that identity. + +Collapse preserves BlueId. Replacing a verified materialized node with a pure reference to its known BlueId yields the same exact node and the same parent identity. + +Resolution preserves Source-document meaning. A Source Document and its complete Resolved Form derive the same BlueId after the Resolved Form is canonicalized. + +A Resolved Form is not generally direct BlueId Input. It may contain inherited or provider-materialized fields that are derivable from the type chain. Directly hashing it is not guaranteed to produce the Source Document's BlueId. + +### 7.4 BlueId Input (normative) + +**BlueId Input** is any node valid for direct application of the BlueId algorithm after BlueId input normalization. + +BlueId Input MUST NOT contain: + +- the `blue` directive; +- unresolved aliases introduced only for authoring convenience; +- illegal payload combinations; +- invalid list-control forms; +- mixed `blueId` reference shapes; +- unresolved cyclic placeholders such as `this#0`, except inside the explicit cyclic-set calculation API defined in §15; +- `$pos` overlays; +- `null` list elements; +- empty-object list elements that have not been normalized to `$empty: true`. + +A node containing `blue` MUST NOT be accepted as direct BlueId Input. The `blue` directive is never identity content. + +### 7.5 Allowed BlueId forms (normative) + +A **plain BlueId** is the Base58 encoding of a SHA-256 digest using the following alphabet: + +```text +123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz +``` + +Blue Language 1.0 does not define alternative BlueId alphabets. A registry MAY define aliases or packaging metadata, but MUST NOT redefine the BlueId hash alphabet. + +A plain BlueId MUST be the canonical Base58 encoding of exactly 32 bytes, the output length of SHA-256. Implementations MUST reject non-canonical Base58 encodings, strings containing characters outside the BlueId alphabet, and strings that decode to any length other than 32 bytes. + +A plain BlueId MUST NOT contain `#`. The `#` suffix syntax is reserved for cyclic-set member BlueIds. + +A valid unprefixed plain BlueId always denotes the BlueId v1 form defined here. A future incompatible BlueId version MUST use syntax that is not valid as a plain BlueId v1 and MUST NOT reinterpret an existing valid v1 string. + +The ZERO_BLUEID sentinel defined in §15.2 is not a plain BlueId because the character `0` is not in the BlueId alphabet. + +A **cyclic-set member BlueId** has the form: + +```text +# +``` + +where `MASTER` is the plain BlueId of the ordered cyclic set list and `index` is a non-negative decimal integer. + +`this#` is an algorithm-internal placeholder accepted only by the explicit cyclic-set calculation API defined in §15. It MUST NOT appear in ordinary BlueId Input or provider-stored content. + +--- + +## 8. Types, Overlays, and Subtyping + +### 8.1 Any node can be a type (normative) + +There is no schema-versus-instance bifurcation in Blue. Any node can appear under `type`. + +If `T` is used in `type: T`, then `T` contributes: + +- structure; +- nested type chains; +- schema constraints; +- fixed values. + +A type is an **overlay source**, not a class declaration. + +### 8.2 Fixed-value invariant (normative) + +A concrete value embedded in a type is immutable in descendants at that path. A descendant MUST NOT replace, remove, or contradict that value. Any attempted override MUST fail resolution. + +For example, if a type fixes: + +```yaml +country: + value: PL +``` + +then a descendant cannot resolve with: + +```yaml +country: + value: US +``` + +### 8.3 Fixed-value equality (normative) + +Fixed-value equality is evaluated after preprocessing and wrapper normalization. + +- Scalar equality compares the parsed scalar value and effective scalar type. +- Object and list equality compares the BlueId of the normalized subtree. +- `name` and `description` are content for fixed-value equality. Matcher neutrality applies to type/shape matching, not to identity equality of fixed values. + +Scalar payload equality compares parsed scalar value and effective scalar type. Full fixed-node equality compares the normalized Blue node identity, including `name`, `description`, metadata, and payload. Thus a descendant may not change labels on an inherited fixed-value node, because doing so changes the fixed node's identity. + +Therefore these are equal after wrapper normalization: + +```yaml +city: Warsaw +``` + +```yaml +city: + value: Warsaw +``` + +but these are different fixed values because labels are identity content: + +```yaml +city: + name: City + value: Warsaw +``` + +```yaml +city: + name: Location + value: Warsaw +``` + +Valid label override on declaration-only field: + +```yaml +# Parent type +city: + name: City + type: Text + +# Descendant +city: + name: Location + value: Warsaw +``` + +Invalid label override on fixed-value field: + +```yaml +# Parent type +city: + name: City + value: Warsaw + +# Descendant +city: + name: Location + value: Warsaw +``` + +The second case fails because the inherited fixed node includes the label `name: City` as identity content. + +### 8.4 Subtyping and Liskov substitutability (normative) + +When resolving, descendants MUST satisfy: + +1. **No fixed-value override.** Immutable values inherited from types cannot be changed. +2. **Type compatibility.** A descendant type at a path must be equal to or a subtype of the inherited type at that path (§8.4.1). +3. **Additive structure.** Guaranteed fields cannot be deleted. +4. **Collection compatibility.** `itemType`, `keyType`, and `valueType` compatibility must be preserved. + +Every instance of a subtype MUST be substitutable for its parent. + +If `itemType`, `keyType`, or `valueType` is inherited at a path, a descendant that omits the field inherits it. A descendant MAY narrow the inherited type by supplying an equal type or subtype. A descendant MUST NOT widen, remove, or replace the inherited type with an incompatible type. + +Omitting `itemType`, `keyType`, or `valueType` means unconstrained only when there is no inherited effective type constraint at that path. + +### 8.4.1 Formal subtype relation (normative) + +For Blue Language 1.0, `T <: P` ("T is a subtype of P") iff resolving `T` as a descendant overlay of `P` succeeds under the resolution rules in §10, and every valid instance of `T` is substitutable where an instance of `P` is required. + +A subtype check MUST ignore `name` and `description` for matcher/type-shape purposes, but fixed-value equality still includes `name` and `description` because they are identity content (§8.3). + +For each path contributed by parent type `P`, subtype `T` MUST satisfy all of the following: + +1. **Fixed values preserved.** If `P` fixes a scalar, object, list, or subtree value at a path, `T` MUST preserve the same fixed value under §8.3. +2. **Guaranteed structure preserved.** If `P` guarantees a field or list prefix element, `T` MUST keep it present in all valid instances unless a specific list merge rule explicitly refines it without removal. +3. **Schema constraints compatible.** Every schema constraint contributed by `P` MUST remain satisfied by `T`. Additional constraints in `T` are allowed only when their intersection with inherited constraints is non-empty and not weaker. +4. **Type constraints narrowed only.** If `P` declares `type`, `itemType`, `keyType`, or `valueType` at a path, `T` may repeat the same type or provide a subtype. It MUST NOT omit, widen, or replace the inherited effective type constraint with an incompatible type. +5. **Payload kind compatible.** Scalar, list, and object payload kinds MUST remain compatible with inherited guarantees. A subtype MUST NOT turn an inherited scalar requirement into a list/object requirement, or vice versa, unless resolution can prove the inherited requirement is not applicable. +6. **List policies preserved.** An inherited `mergePolicy: append-only` MUST remain append-only. A descendant MUST NOT weaken append-only to positional. If no merge policy is inherited and none is authored, the effective default is positional. + +Equivalently, `T <: P` when the Resolved Form produced by resolving `T` over `P` is valid and does not violate any invariant or guarantee of `P`. + +If checking `T <: P` requires resolving a type chain that revisits a type already on the active resolution stack, resolution MUST fail with a type-cycle error (§10.2.1). + +### 8.4.2 Nominal core type identity (normative) + +The canonical core primitive and collection types `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` are **nominal** Blue Language types identified by their canonical registry BlueIds. + +A type resolving to one of these canonical core types is compatible with another such type only when the canonical registry BlueId is equal, unless the canonical registry explicitly declares a subtype relationship. Blue Language 1.0 declares no implicit subtype relationship between distinct core types. + +Matcher-neutral treatment of `name` and `description` applies to structural field matching and subtype shape checks. It does **not** make two different canonical registry type identities interchangeable. If a core type description changes and therefore the type BlueId changes, it is a different nominal type. + +Examples: + +- The canonical `Integer` type is compatible with itself by registry BlueId. +- A node named `Integer` with a different description and different BlueId is not the canonical `Integer` type. +- `Integer` and `Double` are not subtypes of each other in Blue Language 1.0. + +### 8.5 Instance-as-type (normative) + +Nodes representing individuals can be used as types. + +For example: + +- `Alice` may have `type: Person`. +- `Alice Smith` may have `type: Alice`. + +All fixed values in `Alice` become invariants in `Alice Smith`. Alice's top-level `name` and `description` do not flow to Alice Smith (§4.6). + +### 8.6 Requirement overlays (normative) + +An ancestor may partially constrain a subtree without binding a concrete type at that path. + +Example: + +```yaml +# Parent +name: A +prop1: + x: 1 + schema: + minFields: 1 +``` + +A descendant may later set: + +```yaml +name: B +type: A +prop1: + type: Some +``` + +This is valid only if the merged result still satisfies all overlay obligations, including fixed values and schema constraints. If the overlay had a type, the descendant's type must be equal to or a subtype of that type. + +If the overlay forces `x = 1` but `Some` forces `x = 2`, resolution MUST fail. + +### 8.7 Specialization versus expansion (normative distinction) + +**Expansion** materializes a verified reference to an existing node. It reveals more of the same exact node and MUST preserve BlueId. + +**Specialization** is the authoring act of creating a new node whose `type` points to another node and whose overlay adds compatible, more specific meaning. Specialization is governed by the fixed-value, subtype, merge, and schema rules in this section. A specialized node is not the node it specializes and normally has a different BlueId. + +Example: + +```yaml +# Existing node used as a type +name: Price +amount: + type: Integer +currency: + type: Text +``` + +```yaml +# New specialization +name: PLN Price +type: + blueId: +currency: PLN +``` + +Expanding `` reveals the existing `Price` node. Creating `PLN Price` specializes `Price` and creates a new node. Implementations and documentation MUST NOT use these terms interchangeably. + +The word **extension** remains appropriate for unrelated concepts such as implementation extensions or separately specified preprocessing extensions. In this specification, the formal type-and-overlay concept is **specialization**. + +--- + +## 9. Schema Constraints + +### 9.1 Attaching schema (normative) + +A materialized `schema` object or a pure reference to such an object MAY be attached to any node. An operation that needs the constraints behind a pure reference MUST expand and verify that reference before interpreting the schema. + +All schema constraints accumulate along the type chain. Compatible constraints are intersected according to §9.9. Irreconcilable constraints MUST fail resolution. + +### 9.2 Schema vocabulary (normative) + +Only the keywords listed in §§9.3-9.8 are valid inside a materialized `schema` object. Implementations MUST reject any other key after a referenced schema object has been expanded and verified. The `blueId` key of the pure-reference wrapper is not a schema keyword and is never interpreted as one. + +The valid schema keywords are: + +```text +required, +minItems, maxItems, uniqueItems, +minFields, maxFields, +minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, +minLength, maxLength, +enum +``` + +A schema object MUST NOT contain any key outside this list. + +### 9.2.1 Schema keyword value types (normative) + +| Keyword | Required value shape | +|---|---| +| `required` | boolean | +| `minItems`, `maxItems`, `minFields`, `maxFields`, `minLength`, `maxLength` | non-negative integer in the safe JSON numeric integer range | +| `uniqueItems` | boolean | +| `minimum`, `maximum`, `exclusiveMinimum`, `exclusiveMaximum`, `multipleOf` | numeric scalar or explicit numeric scalar node | +| `enum` | list of scalar values or explicit scalar nodes | + +A schema keyword value with the wrong shape MUST be rejected. Implementations MUST NOT coerce schema keyword values across scalar types. + +### 9.2.2 Schema applicability (normative) + +Each schema keyword applies only to the effective node kind for which it is defined. + +- String constraints apply only to effective Text values. +- Numeric constraints apply only to effective Integer or Double values. +- List constraints apply only to effective list payloads. +- Object field-count constraints apply only to effective object payloads. +- `enum` applies to scalar values unless an explicit scalar-node enum entry is used. +- `required` applies to the child field declaration at the path where it appears. + +If a schema keyword is evaluated against an incompatible effective node kind, validation MUST fail with a schema violation. Implementations MUST NOT silently ignore incompatible schema keywords. + +### 9.2.3 Required fields (normative) + +`required: true` on a child field declaration requires that the field be semantically present in resolved descendants. + +A required field is satisfied only if the resolved child node contains at least one of: + +- a scalar payload `value`; +- a list payload `items`, including an empty list; +- an object payload with at least one ordinary child field; +- a pure reference; +- a fixed payload or fixed subtree inherited from an ancestor type. + +A metadata-only child declaration, such as a node containing only `type`, `schema`, `name`, or `description`, does not by itself satisfy `required: true`. + +If a field is required but has no semantic payload or fixed inherited content after resolution and cleaning, validation MUST fail. + +### 9.2.4 Field counting (normative) + +`minFields` and `maxFields` count ordinary child fields of the effective object payload after resolution and object-field cleaning. + +Reserved language fields such as `name`, `description`, `type`, `schema`, `contracts`, `value`, and `items` do not count as ordinary fields. + +Fields removed by object-field cleaning do not count. Inherited ordinary child fields that are materialized in the Resolved Form do count. + +### 9.3 Presence + +```yaml +required: true +``` + +When a schema with `required: true` is attached to a child field in a type or object overlay, that field MUST be semantically present in resolved descendants according to §9.2.3. If used at a document root, `required` is trivially satisfied by the existence of the root node. + +### 9.4 Lists + +```yaml +minItems: +maxItems: +uniqueItems: true | false +``` + +`maxItems` MUST be greater than or equal to `minItems` when both are present. + +`uniqueItems: true` compares items by item BlueId, not by textual rendering. + +### 9.5 Objects + +```yaml +minFields: +maxFields: +``` + +`maxFields` MUST be greater than or equal to `minFields` when both are present. + +The term **fields** is used because Blue objects have direct ordinary fields and no `properties` wrapper. + +### 9.5.1 Dictionary direct encoding validation (normative) + +For direct Dictionary object encoding, each direct key MUST be valid under the effective `keyType`. + +For direct object encoding, `keyType` MUST resolve to one of the scalar key types with a canonical textual representation: Text, Integer, Double, or Boolean. If `keyType` is omitted and no effective `keyType` is inherited, it defaults to Text. + +A key's serialized object-member name MUST be exactly the canonical textual form of the parsed key value. If two key values canonicalize to the same object-member string, the document has a duplicate key conflict and MUST be rejected. + +Every value in a Dictionary with an effective `valueType` MUST resolve as an instance of, or subtype-compatible with, the effective `valueType`. + +Applications needing arbitrary non-scalar keys or reserved-key collisions MUST use an application-defined escaped representation rather than direct object encoding. + +### 9.6 Numerics + +```yaml +minimum: number +maximum: number +exclusiveMinimum: number +exclusiveMaximum: number +multipleOf: number +``` + +Numeric schema keyword values MAY be authored in either scalar form or explicit scalar-node form. + +Scalar form: + +```yaml +schema: + minimum: 5 +``` + +Explicit scalar-node form: + +```yaml +schema: + minimum: + type: Integer + value: "9007199254740992" +``` + +A quoted decimal string without explicit `type: Integer` is Text and MUST NOT be accepted as a numeric constraint. + +Rules: + +- `minimum: m` means the numeric value must be greater than or equal to `m`. +- `maximum: m` means the numeric value must be less than or equal to `m`. +- `exclusiveMinimum: m` means the numeric value must be strictly greater than `m`. +- `exclusiveMaximum: m` means the numeric value must be strictly less than `m`. +- `multipleOf` must be greater than zero. + +If multiple numeric constraints appear in the type chain, the value must satisfy all of them. For integer `multipleOf` constraints, implementations MUST combine compatible constraints using least common multiple (LCM). The effective merged schema MUST contain one `multipleOf` value equal to that LCM, and the Resolved Form and Canonical Identity Input MUST NOT preserve an implementation-specific list of equivalent integer `multipleOf` constraints. + +For `Double` `multipleOf`, both the tested value and the `multipleOf` constraint are interpreted as their exact IEEE 754 binary64 rational values after parsing. A Double value `v` satisfies `multipleOf: m` iff `m > 0` and the exact rational quotient `v / m` is an integer. Implementations MUST NOT use epsilon comparisons, decimal string rounding, host-language modulo on binary floating point, or implementation-specific approximation. + +For cross-type numeric comparisons, an `Integer` value is interpreted as an exact rational integer. A `Double` bound or value is interpreted as its exact IEEE 754 binary64 rational value. Comparison between Integer and Double uses exact rational comparison. + +A numeric token that cannot be parsed to a finite IEEE 754 binary64 value under §2.4 is invalid before schema evaluation. + +Implementations MAY use arbitrary-precision rational arithmetic internally to implement these predicates. They MUST NOT expose host floating-point rounding differences in conformance behavior. + +Numeric schema keyword values follow the same numeric representation rules as scalar values (§2.4). Integer constraints outside the safe JSON numeric integer range MUST be represented as typed Integer scalar nodes that preserve exact integer identity. Quoted decimal text without explicit Integer typing is Text and MUST NOT be treated as a numeric schema constraint. + +### 9.7 Strings + +```yaml +minLength: +maxLength: +``` + +Length is measured in Unicode code points. `maxLength` MUST be greater than or equal to `minLength` when both are present. + +### 9.8 Enumerations + +```yaml +enum: [v1, v2, ...] +``` + +Enumeration values are scalar Blue values. They MAY be authored as bare scalars when unambiguous, or as explicit scalar nodes with `type` and `value` when type disambiguation is required, for example for large integers represented as quoted canonical decimal text. Equality is by parsed scalar value, effective scalar type, and canonical JSON value semantics, not by textual rendering. + +`enum` comparison is performed after preprocessing and scalar type inference. Therefore the untyped enum entry `1` is an `Integer`, while `1.0` and `1e0` are `Double`. A quoted decimal string is Text unless authored as an explicit `Integer` scalar node. + +Example with a large integer enum value: + +```yaml +schema: + enum: + - 1 + - 1.0 + - type: Integer + value: "9007199254740992" +``` + +The first two enum entries above are distinct because their effective scalar types are different. + +There is no separate `const` keyword. A fixed value in a type enforces a constant. + +### 9.8.1 Enumeration normalization (normative) + +`enum` is a set of allowed scalar identities. Authoring order is not semantic. + +During schema validation, schema merge, and canonicalization, each enum entry MUST be normalized to its typed scalar identity: effective scalar type plus canonical scalar value. Duplicate entries with the same typed scalar identity are redundant and MUST be removed in the effective schema. + +The canonical enum representation MUST sort entries by the RFC 8785 canonical JSON byte sequence of their typed scalar identity form. If two entries have identical canonical bytes, they are duplicates and only one is retained. + +Therefore these schemas are semantically equivalent and MUST canonicalize identically: + +```yaml +schema: + enum: [A, B] +``` + +```yaml +schema: + enum: [B, A, A] +``` + +The effective canonical enum contains `A` and `B` once each, in the canonical ordering defined above. + +### 9.9 Schema merge rules (normative) + +When schemas accumulate along the type chain, implementations MUST merge keyword constraints as follows: + +| Keyword | Merge rule | Failure case | +|---|---|---| +| `required` | logical OR | never, for the keyword itself | +| `minItems` | maximum | merged `minItems > maxItems` | +| `maxItems` | minimum | merged `maxItems < minItems` | +| `uniqueItems` | logical OR | never, for the keyword itself | +| `minFields` | maximum | merged `minFields > maxFields` | +| `maxFields` | minimum | merged `maxFields < minFields` | +| `minimum` | strongest lower bound | incompatible with upper bounds | +| `maximum` | strongest upper bound | incompatible with lower bounds | +| `exclusiveMinimum` | strongest exclusive lower bound | incompatible with upper bounds | +| `exclusiveMaximum` | strongest exclusive upper bound | incompatible with lower bounds | +| `multipleOf` | all constraints must hold; integer constraints MUST be merged to their LCM; Double constraints MUST be evaluated by exact rational arithmetic over IEEE 754 binary64 values under §9.6 | no possible numeric value satisfies all constraints | +| `minLength` | maximum | merged `minLength > maxLength` | +| `maxLength` | minimum | merged `maxLength < minLength` | +| `enum` | normalize both sides under §9.8.1, then intersect by typed scalar identity; canonical effective enum is duplicate-free and sorted under §9.8.1 | empty intersection | + +For lower/upper-bound interactions, an exclusive bound at the same numeric value is stricter than an inclusive bound. For example, `minimum: 5` merged with `exclusiveMinimum: 5` yields `exclusiveMinimum: 5`. + +--- + +## 10. Resolution + +### 10.1 Resolution (normative) + +**Resolution** applies Blue type and overlay semantics to a Source Node. It follows effective type links, merges inherited and instance contributions, enforces fixed values, applies list merge rules, accumulates schema constraints, and validates the resolved result. + +A **complete Resolved Form** contains the complete semantic result for the root being resolved. + +A **limited resolution result** contains only explicitly demanded paths and the supporting content needed to establish them. It is an operation result, not a different Blue node. Coverage and completeness information are out-of-band and do not affect BlueId. + +For every path covered by limited resolution, the resulting value, effective type, and applicable constraints MUST be exactly the same as in complete resolution of the same source with the same provider content. + +A complete Resolved Form is the input to minimization and canonicalization. An incomplete result MUST NOT be used to calculate a Source Document's BlueId, claim complete schema validity, or produce a whole-node Minimized Overlay. + +### 10.2 Complete resolution algorithm (normative) + +Given a Source Node `S`, complete resolution performs: + +1. **Preprocess** `S` (§6), producing a Preprocessed Document. +2. **Resolve the type chain.** If `S.type` exists, recursively resolve it. If the type is a pure reference, expand it through a provider and verify the fetched content (§12.4). The result is the ancestor Resolved Form `A`. +3. **Merge ancestor and source.** Merge `A` into target `T`, then merge `S` into `T`: + - **Root labels:** when merging a type into an instance root, do not copy the type root's `name` or `description` onto the instance root (§4.6). + - **Values:** copy if absent; if both are present, they must be equal under fixed-value equality (§8.3). + - **Types:** assign and propagate under §8. + - **Schema:** accumulate under §9. + - **Object fields:** merge recursively; children must remain compatible. + - **Lists:** merge under §11. + - **Contracts:** preserve and merge as identity-bearing content under §4.4; do not execute. +4. **Validate schema** after merging. +5. **Produce the complete Resolved Form.** Implementations MAY freeze it into an immutable snapshot when needed. + +Schema validation is performed after inherited and instance values are merged at a node. Therefore an inherited schema applies to inherited fixed values, type-derived fields, and instance-supplied values in the final Resolved Form. + +Type-chain resolution is depth-first: the effective ancestor type is resolved before it is merged into the descendant target. A resolver MUST track the active type-resolution stack for cycle detection. + +### 10.2.1 Type-chain cycle detection (normative) + +Type-chain cycles are invalid for Blue Language 1.0 resolution. + +If resolving a node requires resolving a type that is already present on the active type-resolution stack, resolution MUST fail deterministically with a type-cycle error. + +Example invalid cycle: + +```yaml +# A +name: A +type: + blueId: + +# B +name: B +type: + blueId: +``` + +Circular-set BlueIds (§15) identify cyclic document sets. They do not make cyclic inheritance or cyclic type chains resolvable. Blue Language 1.0 does not define fixed-point type semantics. + +### 10.2.2 Complete resolution pseudocode (informative) + +```text +resolve_complete(source, provider): + S = preprocess(source) + if S.type exists: + T_ref = normalize_type_reference(S.type) + T_node = expand_reference(T_ref, provider) + A = resolve_complete(T_node, provider) + else: + A = empty node + R = merge_as_instance(ancestor=A, instance=S, path="/") + validate_schema_recursively(R) + return ResolvedForm(R, provenance, complete=true) + +merge_as_instance(ancestor, instance, path): + T = copy_type_derived_content(ancestor, path) + if path == "/" and ancestor is the effective type of instance: + do not copy ancestor.name or ancestor.description to T + merge reserved metadata using field-specific rules + merge ordinary child fields recursively + merge lists using §11 + merge contracts using §4.4 + reject fixed-value, type, schema, or payload-kind conflicts + record provenance for each retained contribution + return T +``` + +Precise implementation structure is not normative. The observable complete Resolved Form, validation behavior, canonicalization provenance, and the resulting Source-derived BlueId are normative. + +### 10.3 Limited resolution (normative) + +A resolver MAY accept out-of-band **Limits** that identify demanded paths or bound work. Typical limits include selected operation paths, maximum reference expansions, maximum graph depth, and maximum nodes visited. + +For a requested path, limited resolution MUST resolve the complete semantic dependency closure required to establish that path. This may include: + +- the source node and ancestors along the path; +- effective type nodes and inherited fields contributing at the path; +- applicable schema and collection constraints; +- object keys or list positions required by the requested operation; +- provider content needed to verify and interpret those contributions. + +A limited resolver MUST NOT: + +- treat an unexpanded reference as an empty object or missing field; +- report a field as semantically absent unless absence has been established from the required source and type contributions; +- return a guessed value when a limit prevents completion; +- expose provider, cache, or storage layout as semantic content. + +When limits prevent a demanded result from being established, the operation MUST fail with a deterministic limit/incomplete result or explicitly report that the requested path is incomplete. It MUST NOT return a normal successful absence result. + +Implementations may return demanded values directly or may return a partially materialized result with out-of-band coverage metadata. In either case, all covered values MUST equal complete resolution. + +### 10.4 Resolution provenance (normative) + +A conforming implementation performing complete resolution for canonicalization MUST track enough provenance to canonicalize deterministically. For each resolved path, it MUST be able to determine whether content was: + +- **instance-supplied** by the Source Document after preprocessing; +- **type-derived** from an ancestor type; +- **provider-materialized** from a `blueId` reference; +- **preprocessing-derived** from mandatory or declared preprocessing; +- **merge-derived** from compatible instance and type contributions. + +Limited resolution need track only the provenance required for its covered paths, unless the result will later be completed for canonicalization or minimization. + +The exact internal representation is implementation-defined. + +### 10.5 Identity guarantee (normative) + +Resolution preserves semantic identity. A Source Document and its complete Resolved Form derive the same BlueId when the complete Resolved Form is canonicalized. + +Implementations MUST NOT assume that directly hashing a Resolved Form produces the Source Document's BlueId. + +Limited resolution does not create a new identity. It exposes only part of the semantics of the same source node. + +### 10.6 Provider failures (normative) + +A conforming implementation MUST expand referenced content when that content is required for the requested resolution, canonicalization, minimization, collapse verification, or validation. If required content is unavailable or fails verification, the operation MUST fail deterministically. Implementations MUST NOT silently substitute empty content for missing references. + +Unrelated references outside the demanded dependency closure need not be fetched. + +### 10.7 Limits (normative) + +Limits are out-of-band operation controls. They MUST NOT be serialized into the Blue node, included in BlueId calculation, or alter the result that complete processing would produce. + +An implementation SHOULD support path, depth, node-count, and reference-count limits for expansion and resolution of large graphs. + +A result is complete only when every path and constraint required by the requested operation has been established. An incomplete result MUST NOT be used for whole-node Source Document BlueId calculation, whole-node minimization, or a claim of complete validation. + + +### 10.8 Demand-limited operation outcomes (normative) + +A demand-limited Language operation asks a semantic question about one or more selected paths without requiring complete graph expansion or complete document resolution. + +Common demands include exact node identity, node kind, semantic existence, one object child, complete object keys, list length, one list item, effective type, applicable constraints, or the resolved value at a path. + +The exact host-language API is not normative. A conforming operation MUST deterministically establish exactly one of these semantic conclusions: + +- the requested result is established for the declared coverage; +- semantic absence is established from sufficient direct and inherited information; +- the request could not be completed because a limit, unavailable reference, unsupported provider operation, or another explicitly reported condition prevented proof; +- the demanded content or its required semantic closure is invalid. + +Implementations MAY expose named result variants such as `Established`, `Absent`, `Incomplete`, and `Invalid`, but this specification does not require those class names or one particular public API. + +Rules: + +- a pure reference, cache miss, provider timeout, direct-node limit, or resolution limit MUST NOT be treated as semantic absence; +- a result established from graph-equivalent inline, collapsed, expanded, cached, or segmented forms MUST be the same once the same logical identities are available; +- a result that did not establish complete required coverage MUST NOT be used for whole-node canonicalization, Source Document BlueId calculation, complete minimization, or a claim of complete validation; +- diagnostic information about outstanding identities or covered paths is out-of-band and does not affect Blue content or identity. + +### 10.9 Cache neutrality and diagnostic information (normative) + +A Language implementation MAY expose diagnostic information such as demanded identities, covered paths, provider outcomes, semantic steps, or implementation timings. + +Such diagnostics are not Blue content and do not affect identity. Cache state, prefetching, batching, storage pages, or previous operations MUST NOT change a successful semantic result or turn incomplete evidence into complete evidence. + +Layered runtime specifications MAY define their own deterministic work ledger over Language operations. Such a ledger is not part of Blue content-language identity and MUST NOT redefine the semantic outcomes in §10.8. + +## 11. Lists, Merge Policies, and List Control Forms + +### 11.1 Authoring model (normative) + +A list field SHOULD be authored in typed form when list semantics matter: + +```yaml +: + type: List + itemType: + mergePolicy: append-only | positional + items: + - ...elements... +``` + +A surface list is permitted for simple cases: + +```yaml +tags: [a, b, c] +``` + +Typed form is REQUIRED when `mergePolicy`, anchors, or overlays are used. + +Every element of a resolved list with an effective `itemType` MUST resolve as an instance of, or subtype-compatible with, the effective `itemType`. If an item cannot be resolved or is incompatible with `itemType`, validation MUST fail. + +If `itemType` is omitted and no effective inherited `itemType` exists, list elements are unconstrained by item type. + +### 11.2 Allowed item forms inside `items` (normative) + +Each item inside `items` MUST be exactly one of the following forms after Source Document preprocessing. + +#### Normal element + +```yaml +- +``` + +A normal element is content. + +#### Append anchor + +```yaml +- $previous: + blueId: +``` + +Rules: + +- `$previous` is allowed only as the first item. +- The shape MUST be exactly one top-level `$previous` key whose value is an object with exactly one `blueId` key. +- `$previous` is never content. + +#### Positional overlay + +Map overlay: + +```yaml +- $pos: 1 + ...overlay fields... +``` + +Replacement overlay for an object: + +```yaml +- $pos: 1 + $replace: + type: Address + city: Warsaw +``` + +Replacement overlay for a list: + +```yaml +- $pos: 1 + $replace: + items: + - A + - B +``` + +Replacement overlay for a pure reference: + +```yaml +- $pos: 1 + $replace: + blueId: X +``` + +Rules: + +- `$pos` MUST be a non-negative integer using zero-based indexing. +- `$pos` is valid only when `mergePolicy: positional`. +- A `$pos` item without `$replace` is a map overlay. It is valid only when the inherited element at that index is an object-compatible node. If the inherited element is scalar, list, or pure reference, the overlay MUST use `$replace` and remain type-compatible. +- `$pos` overlays are consumed by resolution and do not appear as content in the final list. +- `$replace` is valid only inside a `$pos` item. Its value is a full Blue node used to replace the inherited element, subject to type and schema compatibility. +- For scalar replacement, the concise form below is equivalent to `$replace: { value: B }`: + +```yaml +- $pos: 1 + value: B +``` + +The `value` form MUST NOT be used to carry list or object replacements. Use `$replace` for non-scalar replacements. + +#### Placeholder element + +```yaml +- $empty: true +``` + +`$empty: true` is content. It is a real element that occupies a position and affects BlueId. It is distinct from `null`, `{}`, and `[]`. + +The shape MUST be exactly one top-level `$empty` key whose value is the boolean `true`. `$empty: false`, `$empty: null`, and `$empty` with sibling fields are invalid as list placeholder elements. + +### 11.3 Scope of list control keys (normative) + +The special keys `$previous`, `$pos`, `$replace`, and `$empty` are recognized only as top-level keys of elements inside a list payload. + +`$empty` is valid in any list payload. + +`$previous`, `$pos`, and `$replace` are list overlay controls. They are valid only when the list is being resolved as a typed or overlay-capable list. Authors SHOULD use the typed list form when using these controls. + +Outside list-control position, `$previous`, `$pos`, `$replace`, and `$empty` are ordinary field names unless another specification gives them meaning. They do not act as list controls outside list elements. + +### 11.4 Default merge policy (normative) + +If no effective `mergePolicy` is inherited and no `mergePolicy` is authored on the list, resolvers MUST assume: + +```yaml +mergePolicy: positional +``` + +If an inherited list has an effective `mergePolicy`, a descendant list overlay that omits `mergePolicy` inherits that effective policy. A descendant MAY repeat the same `mergePolicy`. + +A descendant MUST NOT change an inherited `mergePolicy`. If an effective `mergePolicy` is inherited, omission by the descendant means inheritance, not defaulting. If no policy is inherited and no policy is authored, the effective default is `positional`. + +In particular, `append-only` MUST NOT be weakened to `positional`. + +For histories, ledgers, timelines, and append-only logs, authors MUST specify: + +```yaml +mergePolicy: append-only +``` + +### 11.5 Semantics of `null`, `{}`, `[]`, and `$empty` (normative) + +Blue distinguishes object-field absence from list position. + +#### Object fields + +In object fields, `null` means no information. Before hashing: + +- fields whose value is `null` MUST be omitted; +- fields whose value normalizes to an empty object `{}` MUST be omitted; +- empty lists `[]` MUST be preserved. + +This removal is recursive and may cascade. + +#### List elements + +List elements are positional. Implementations MUST NOT delete list elements during cleaning, because doing so changes list length and shifts later indices. + +In Source Documents, a list element that is `null`, an empty object `{}`, or an object that recursively normalizes to an empty object after object-field cleaning MUST be normalized to: + +```yaml +$empty: true +``` + +It MUST NOT be deleted from the list, because list position is content. + +In Canonical Identity Input and BlueId Input, `null` list elements and empty-object list elements MUST NOT appear. They MUST already have been normalized to `$empty: true` or rejected. + +The marker `$empty: true` is content. It occupies a list position and affects BlueId. + +Empty lists `[]` are preserved as list elements and are distinct from `$empty: true`. + +Consequences: + +```text +id([A, null, B] after preprocessing) == id([A, {$empty: true}, B]) +id([A, null, B] after preprocessing) != id([A, B]) +id([A, {}, B] after preprocessing) == id([A, {$empty: true}, B]) +id([A, [], B]) != id([A, {$empty: true}, B]) +``` + +### 11.6 Merge semantics (normative) + +Let `P` be the resolved parent list and `C` be the child overlay list. + +#### `append-only` + +For `mergePolicy: append-only`: + +- inherited indices `< length(P)` MUST NOT be modified or deleted; +- `$pos` overlays are forbidden; +- normal items after the inherited prefix are appended; +- an optional `$previous` anchor may appear as the first child item. + +Errors: + +- any `$pos` overlay; +- malformed `$previous`; +- `$previous` not first; +- repeated `$previous`; +- attempted modification, removal, or reordering of the inherited prefix. + +#### `positional` + +For `mergePolicy: positional`: + +- `$pos: i` refines inherited index `i`, where `0 <= i < length(P)`; +- map overlays merge field-wise, subject to type and schema compatibility; +- `$replace` overlays replace the inherited element, subject to compatibility; +- scalar `value` overlays replace the inherited element with a scalar node, subject to compatibility; +- normal items without `$pos` are appended after the inherited prefix in author order; +- reordering, removal, and gaps within the inherited prefix are forbidden. + +Errors: + +- `$pos` missing or non-integer; +- `$pos` out of range; +- duplicate overlays for the same index; +- type or schema incompatibility at the index; +- attempted reordering or removal of parent elements; +- `value` used as a non-scalar positional replacement. + +### 11.7 `$previous` validation (normative) + +`$previous` is a resolution-time anchor. + +During resolution, the resolver MUST verify that the inherited prefix hashes to `$previous.blueId`. If it does not match, resolution MUST fail. + +During direct BlueId calculation of valid BlueId Input that already contains a leading `$previous`, the anchor MAY be used as a list-fold seed (§14.8). Validity of the anchor is a precondition of the input. An implementation performing direct BlueId calculation without resolution context MAY reject `$previous` inputs. + +A direct hasher MUST NOT silently ignore `$previous` and recompute when it cannot verify the prefix. A direct hasher has no provider or inheritance context and therefore cannot determine whether an anchor is stale. + +`$previous` does not define a different list identity algorithm. It exposes a prefix identity that, once verified, may be used as the seed of the ordinary list fold. If the inherited prefix is `[a1, ..., an]` and `$previous.blueId` is verified as `id([a1, ..., an])`, appending `b1, ..., bk` requires only `k` additional fold steps after the BlueIds of the appended elements are established. See §14.7.2. + +### 11.8 List conformance checklist (normative) + +Implementations supporting lists MUST satisfy: + +- `id([])` is defined and distinct from absent values and cleaned object fields; +- `[A]` hashes differently from `A`; +- `[[A, B], C]` hashes differently from `[A, B, C]`; +- Source list `[A, null, B]` normalizes to `[A, {$empty: true}, B]`, not `[A, B]`; +- Source list `[A, {}, B]` normalizes to `[A, {$empty: true}, B]`, not `[A, B]`; +- Source list `[A, {x: null}, B]` normalizes to `[A, {$empty: true}, B]`, not `[A, B]`; +- `$previous` is recognized only as the first item; +- `$previous` mismatch fails resolution; +- `append-only` rejects `$pos`; +- inherited `append-only` remains effective when a child overlay omits `mergePolicy`; +- `positional` accepts valid `$pos` overlays and rejects duplicate or out-of-range overlays; +- `$empty: true` remains content and affects BlueId; +- malformed `$empty` placeholder items are rejected; +- object-field cleaning removes `null` and object fields that normalize to `{}`, but does not delete list positions. + +### 11.9 Worked examples (informative) + +Present-empty vs absent: + +```yaml +# Absent +doc: {} + +# Present-empty +doc: + list: + type: List + items: [] +``` + +Append-only timeline: + +```yaml +# Parent +entries: + type: List + itemType: Timeline Entry + mergePolicy: append-only + items: + - { type: Timeline Entry, ts: "2025-09-01T12:00:00Z", message: A } + - { type: Timeline Entry, ts: "2025-09-01T12:05:00Z", message: B } + +# Child +entries: + type: List + itemType: Timeline Entry + mergePolicy: append-only + items: + - $previous: { blueId: PrevId } + - { type: Timeline Entry, ts: "2025-09-01T12:10:00Z", message: C } +``` + +Positional hole and refinement: + +```yaml +# Parent +entries: + type: List + mergePolicy: positional + items: + - A + - $empty: true + - C + +# Child +entries: + type: List + mergePolicy: positional + items: + - $pos: 1 + value: B +# Resolved: [A, B, C] +``` + +--- + +## 12. References, Providers, Expansion, and Collapse + +### 12.1 Providers (informative) + +A **BlueId provider** retrieves Blue content by BlueId. + +Providers may be local maps, databases, object stores, package registries, network services, or composed provider chains. + +### 12.2 Provider trust model (normative/informative) + +A provider is not trusted merely because it returned content. Returned content MUST verify against the requested BlueId before it is used as that node. + +Provider location, cache state, transfer size, paging, and physical storage layout are not Blue Language semantics. + +### 12.3 Provider content form (normative) + +The default portable provider model returns BlueId Input or cyclic-set-aware member content appropriate to the requested identity. + +A Source Document provider MAY be supported as an implementation extension or registry mode. Such a provider verifies returned content by running Source Document BlueId calculation, not direct BlueId calculation. The provider mode MUST bind the exact Blue Language release, preprocessing environment, canonical registry bindings, and the exact Source Document snapshot or other identity-bearing evidence being resolved. Ambient provider state is never part of Source Document BlueId calculation. A Source Document provider is not the default portable provider model. + +### 12.4 Plain BlueId provider verification (normative) + +For an ordinary BlueId `X`, provider content is valid only if direct BlueId calculation over the returned BlueId Input produces `X`. + +If verification fails, the demanding operation MUST fail deterministically. + +Implementations MUST NOT silently use provider content whose computed BlueId differs from the requested BlueId. + +### 12.5 Cyclic-set member provider verification (normative) + +A cyclic member BlueId `#` is verified in the context of its complete declared cyclic set under §15. The provider or caller must supply enough context to reconstruct and verify the set. + +An implementation MUST NOT verify `#` by hashing the returned member alone. + +### 12.6 Expansion (normative) + +**Expansion** replaces selected pure references with verified materialized content. + +Given: + +```yaml +field: + blueId: X +``` + +expansion fetches content for `X`, verifies it (§12.4), and makes that content available at `field`. Nested references remain collapsed unless they are also demanded by the operation and permitted by its Limits. + +Expansion may begin at a document root that is itself a pure reference. + +Expansion changes representation, not meaning. It MUST preserve BlueId. A pure reference contributes its target BlueId, and verified materialized content contributes that same identity. + +A conforming expansion API SHOULD accept operation paths and limits. Its **semantic demand closure** MUST contain only references needed for the requested result. References left outside that closure, or left collapsed because of a limit, MUST NOT be treated as absent content. + +An implementation MAY physically prefetch additional verified nodes. Prefetched content outside the semantic demand closure MUST NOT enter the operation result, change completeness, affect identity, or alter a layered portable work ledger. Provider caching, internal paging, and physical storage chunks are implementation details and MUST NOT change the expanded result. + +### 12.7 Collapse (normative) + +**Collapse** replaces selected materialized content with a pure reference `{ blueId: X }` to the same node. + +Collapse is permitted when the node's BlueId is known or has been calculated and, for provider-originated content, verification established that identity. The collapsed result MUST be a pure reference with no sibling fields. + +Collapse changes representation, not meaning, and MUST preserve the enclosing node's BlueId. + +An implementation MAY collapse the document root, an object field, a list element, a type node, a workflow body, or any other complete Blue node. It MAY leave other parts materialized. + +### 12.8 Expansion, resolution, and limits (normative) + +Expansion and resolution are composable but distinct: + +- expansion obtains referenced node content; +- resolution interprets type and overlay semantics; +- a resolver expands only references needed for the demanded semantic result; +- unrelated branches may remain collapsed in a successful operation result when their identity is sufficient and their internal content is not needed by that operation; +- a limited result MUST explicitly report incompleteness when demanded semantics cannot be established. + +Limits affect work, not meaning. The same demanded path resolved from an inline node and from a verified pure reference MUST produce the same value and effective type. + +### 12.9 Graph boundary (normative) + +A Blue Document need not be a closed tree. A `{ blueId: ... }` reference may point outside the serialized document. Implementations materialize referenced content only as needed and within configured limits. + +The fact that a referenced node is stored in another file, database row, object-store chunk, or network location has no Blue Language meaning. + +### 12.10 Blue Language operation paths (normative when exposed) + +Blue Language operation paths are out-of-band selectors used for expansion limits, collapse selection, limited resolution, diagnostics, and provenance. They are not Blue content and do not affect BlueId. + +A conforming implementation that exposes path-limited operations MUST support RFC 6901 JSON Pointer paths over the abstract Blue node model: + +- the empty string `""` selects the root node; +- `/field` selects an object field named `field`; +- `/items/0` selects list payload item index `0` in the abstract node model; +- `~0` represents `~`, and `~1` represents `/`, following RFC 6901. + +The wildcard `*`, such as `/spent/*`, is not part of the required Blue Language 1.0 path grammar. Implementations MAY support wildcards as an extension, but portable conformance fixtures MUST use RFC 6901 paths unless a future path-selector specification defines more. + +### 12.11 Direct-node materialization pattern (informative) + +An implementation may keep one selected node materialized while collapsing any or all complete direct children to pure references. This is ordinary expansion and collapse with a depth or path limit; it is not a fifth Language operation or a new node form. + +For an object, such a representation normally retains the complete direct key set, inline identity-bearing metadata such as `name`, `description`, and scalar `value`, and the exact BlueId of every other direct child. For a list, it normally retains list metadata and the ordered exact BlueId of every direct element. Metadata-only nodes, including nodes carrying `type`, `schema`, `mergePolicy`, or `contracts`, follow the same rule: direct identity-bearing content remains available and complete child nodes may be collapsed. + +This representation has the same BlueId as the fully materialized node. Under the map and list hashing rules in §14, the selected direct node can be verified without fetching transitive descendant bodies. This is the language-level reason path-by-path graph navigation is possible. + +### 12.12 Provider and storage guidance (informative) + +A content-addressed provider can support practical lazy expansion by storing every admitted node in direct-node materialization pattern, keyed by exact BlueId, and fetching one direct node at a time along a demanded path. + +A useful provider distinguishes: + +```text +Found verified exact node content is available +NotFound definitive absence in the provider's declared domain +Unavailable transient infrastructure failure +InvalidEvidence returned content failed verification +``` + +These outcomes are provider or host concerns. `NotFound` and `Unavailable` do not mean that a graph path is semantically absent. Provider transport, batching, authorization, storage layout, and retry rules are outside this Language specification. + +The current BlueId algorithm requires a complete direct manifest to verify an ordinary object or list node. It does not provide logarithmic proofs for one member of a very wide direct container. Applications requiring large mutable maps, vectors, text, or blobs SHOULD use bounded-fanout content-addressed structures. + +## 13. Canonicalization and Minimization + +### 13.1 Distinction (normative) + +Blue defines two operations that may both remove explicit content but serve different purposes. + +**Minimization** takes a complete Resolved Form and produces a smaller Source overlay that resolves back to the same complete Resolved Form. Resolution and minimization are semantic counterparts. A minimizer may choose among several valid Source encodings, so minimization is not necessarily unique. + +**Canonicalization** derives the one deterministic BlueId Input used to calculate the BlueId of a Source Document. Canonicalization is an identity operation, not an authoring preference and not necessarily the smallest serialized form. + +The distinction is: + +| Question | Canonicalization | Minimization | +|---|---|---| +| Purpose | Produce identity input | Produce convenient Source form | +| Input | Complete Resolved Form | Complete Resolved Form | +| Output | Canonical Identity Input | Minimized Overlay | +| Unique | Yes | Not necessarily | +| Valid direct BlueId Input | Yes | Not necessarily | +| May contain `$previous`, `$pos`, `$replace` | No | Yes, when valid Source controls | +| Used in Source Document BlueId calculation | Yes | No | +| Must re-resolve as ordinary Source | No | Yes | + +The Source Document BlueId path is: + +```text +complete Resolved Form + -> canonicalize + -> Canonical Identity Input + -> BlueId algorithm + -> Source-derived BlueId +``` + +The optional authoring path is: + +```text +complete Resolved Form + -> minimize + -> Minimized Overlay + -> when processed again: preprocess -> resolve -> canonicalize -> hash + -> same Source-derived BlueId +``` + +**Minimization is not a step in Source Document BlueId calculation.** A runtime processor does not need to minimize a whole document after every read or patch. It may preserve unchanged nodes by BlueId and use ordinary collapse. Whole-node minimization is needed only when a reduced Source overlay is requested. + +### 13.2 Canonical Identity Input (normative) + +A **Canonical Identity Input** is the deterministic identity form derived from a complete Resolved Form. It contains the deterministic identity-bearing content needed for BlueId calculation. It may contain final canonical payloads, including final list payloads, that are not ordinary Source overlays. A Canonical Identity Input MUST be valid BlueId Input. It is not required to be accepted as a Source Document or to re-resolve under ordinary Source overlay semantics. + +The BlueId derived from a Source Document is the BlueId of its Canonical Identity Input. `Content BlueId` is permitted shorthand for that result, not a separate identifier kind. + +**Blue semantic canonicalization** in this section derives the Canonical Identity Input. **RFC 8785 canonical JSON serialization** is a later byte-serialization rule used inside the BlueId algorithm (§14.1). They are distinct operations: semantic canonicalization decides *what exact Blue node is hashed*; RFC 8785 decides *how helper values are serialized deterministically while hashing it*. + +A Canonical Identity Input is unique for a given complete Resolved Form under the selected Blue Language release and canonical registry bindings. The provider may be needed to obtain verified referenced nodes, but its cache, location, response order, availability history, and other ambient state do not participate in canonical identity. + +### 13.3 Minimized Overlay (normative) + +A **Minimized Overlay** is an author-facing reduced Source overlay that re-resolves to the same complete Resolved Form. + +A conforming implementation MUST implement canonicalization. A conforming implementation MAY expose minimization. If it does, every whole-node Minimized Overlay it produces MUST be based on a complete Resolved Form, MUST re-resolve to that same form, and MUST derive the same BlueId through the full Source Document identity pipeline. + +Different minimizers MAY produce different valid Minimized Overlays. Such overlays MAY have different direct BlueIds, but when processed through the full Source Document identity pipeline they MUST derive the same BlueId. + +A Minimized Overlay MAY use authoring controls such as `$previous`, `$pos`, and `$replace` when valid, and MAY collapse complete subtrees to verified pure references under §13.7. + +### 13.3.1 Why list minimization and canonicalization differ (informative) + +Assume an inherited append-only list contributes: + +```yaml +items: + - A + - B +``` + +and the specialized Source adds `C`. The complete Resolved Form contains: + +```yaml +items: + - A + - B + - C +``` + +A useful Minimized Overlay may retain only the relationship to the inherited prefix and the new item: + +```yaml +items: + - $previous: + blueId: + - C +``` + +That is compact Source syntax. It is not the canonical identity form. + +The Canonical Identity Input MUST contain the final list payload and no overlay controls: + +```yaml +items: + - A + - B + - C +``` + +Similarly, a positional Minimized Overlay may use `$pos` to describe only a changed inherited position, while canonicalization applies the overlay and writes the final ordinary list payload. This is why the correct identity pipeline is `resolve -> canonicalize -> BlueId`, not `resolve -> minimize -> BlueId`. + +### 13.4 Canonicalization requirements (normative) + +Given a Resolved Form `R`, canonicalization MUST: + +- preserve all instance contributions that are not derivable from the type chain; +- remove fields fully derivable from the type chain; +- preserve instance-level `name` and `description` when present on the instance; +- not inherit top-level `name` or `description` from the type; +- preserve instance-fixed values that are not derivable from the type chain; +- replace materialized type objects with canonical `type: { blueId: ... }` references when their BlueId is known; +- ensure the Canonical Identity Input contains no type aliases; if an instance supplied a type alias, preprocessing MUST replace it with the canonical `type: { blueId: ... }` reference before resolution; +- for provider-materialized content, preserve the original pure reference when that reference is an instance contribution and the materialized subtree contributes no additional instance-supplied content; +- remove the `blue` directive if present, because it is invalid after preprocessing; +- normalize list placeholders so that list `null` and empty-object elements become `$empty: true`; +- consume all `$pos` overlays and produce final canonical list content; +- produce valid BlueId Input. + +Schema objects included in Canonical Identity Input MUST use normalized effective schema form. In particular, `enum` values are duplicate-free and sorted under §9.8.1, and integer `multipleOf` constraints are represented by the merged LCM value rather than by raw inherited/descendant contributions. + +### 13.5 Canonicalization as deterministic diff (normative) + +Canonicalization can be understood as a deterministic diff between the Resolved Form and the resolved ancestor form contributed by the effective type chain. + +For each node: + +1. If the node has an effective type, include the canonical type reference unless the type reference itself is fully derivable at that path and not required by the canonical identity form. +2. For each reserved metadata field other than `type`, include it only when it is an instance contribution that is not derivable from the ancestor form, except where this specification requires preservation. +3. For each ordinary child field, omit it when the child is fully derivable from the ancestor form. Otherwise include the canonical identity input of the child. +4. For scalar values, omit an inherited fixed value and include an instance value not derivable from the ancestor. +5. For lists, use the canonical list rules in §13.6. +6. After the identity input is constructed, apply BlueId input normalization and object-field cleaning. Empty object fields are omitted. Empty lists are preserved. + +Implementations MUST make all tie-breakers deterministic and covered by conformance vectors. + +### 13.5.1 Canonicalization tie-breakers (normative) + +When multiple candidate identity inputs would represent the same Resolved Form, the Canonical Identity Input MUST be selected by the following tie-breakers, in order: + +1. **Omit derivable non-list content.** A field, metadata entry, or non-list subtree that is fully derivable from the effective type chain MUST be omitted from the Canonical Identity Input, unless another rule in this section explicitly requires it. **List payloads are special:** for list nodes, §13.6 overrides this general omission rule. Canonicalization of a list produces the final canonical list payload for identity calculation, including inherited prefix elements, positional refinements, append-only appends, and `$empty` placeholders after normalization. +2. **Preserve non-derivable instance content.** Content supplied by the instance or Source Document and not derivable from the type chain MUST be preserved. +3. **Use pure references for referenced ancestors/types.** A materialized type or referenced ancestor whose BlueId is known MUST be represented as `{ blueId: X }` in type positions and other reference-preserving positions. +4. **Preserve source pure references materialized only for resolution.** If a Source Document provided a pure reference and the provider materialized it only to resolve or validate content, the Canonical Identity Input MUST prefer the original pure reference form unless the instance supplied an overlay that must be represented. +5. **Consume overlay controls.** `$pos`, `$replace`, `$previous`, source list `null`, and empty-object list elements MUST NOT appear in Canonical Identity Input. Their effects must be represented as ordinary canonical content. +6. **No authoring aliases.** Type aliases and `blue` preprocessing directives MUST NOT appear in Canonical Identity Input. +7. **Deterministic map ordering.** When serializing helper maps or canonical JSON, property order is the order defined by RFC 8785 canonical JSON. No locale-sensitive ordering, implementation insertion order, or host map order is permitted. +8. **Smallest semantic identity input wins.** If two candidate identity inputs both satisfy the rules above, the one with fewer non-derivable fields and fewer materialized subtrees wins. If still tied, the RFC 8785 canonical JSON byte sequence of the candidate identity input is compared lexicographically and the smaller byte sequence wins. + +These rules are part of the Blue Language 1.0 identity definition and MUST be implemented consistently. The conformance fixture suite provides examples but does not replace these rules. + +### 13.6 Canonical list rules (normative) + +Canonical list rules produce final list payload content for identity calculation. + +For list payloads, final canonical list content is the canonical identity form. This rule overrides the general "omit derivable content" tie-breaker in §13.5.1. Blue Language 1.0 does not define a canonical list-diff representation. + +For a list with no inherited prefix, the Canonical Identity Input contains the canonicalized full list. + +For an inherited list under `mergePolicy: append-only`, a Minimized Overlay MAY use a valid `$previous` anchor followed by appended elements. A Canonical Identity Input MUST NOT contain `$previous`. Canonicalization MUST produce the final canonical list payload before hashing. This requirement defines the canonical semantic content; it does not require an implementation to reread or rehash the inherited prefix. When the exact inherited-prefix BlueId is already established and verified, the implementation MAY continue the §14.7 fold from that BlueId and hash only the appended delta. That optimization is not part of the serialized Canonical Identity Input and does not change the resulting BlueId. + +For an inherited list under `mergePolicy: positional`, a Minimized Overlay MAY represent inherited-index refinements using `$pos` overlays. A Canonical Identity Input MUST NOT contain `$pos`. Canonicalization MUST apply all positional overlays and produce the final canonical list payload before hashing. + +A final canonical list payload in Canonical Identity Input is identity input, not an instruction to append to or refine an inherited list under ordinary Source overlay semantics. + +### 13.7 Deterministic collapse during minimization (normative) + +A Minimized Overlay MAY collapse a subtree to `{ blueId: X }` only when: + +1. the subtree's BlueId is known to be `X`; +2. provider verification has established that `X` identifies that content if the subtree came from a provider; +3. collapse at that path is deterministic under the implementation's declared minimization rules; +4. the collapsed overlay re-resolves to the same Resolved Form. + +A Canonical Identity Input MUST follow the deterministic canonicalization rules. Unless this specification explicitly requires collapse at a path, Canonical Identity Input MUST prefer the materialized canonical identity form. Optional collapse is an author-facing minimization feature, not a source of variation in the Source-derived BlueId. + +A Canonical Identity Input MUST NOT depend on implementation-local collapse preferences. + +--- + +## 14. BlueId Algorithm + +### 14.1 Hash function (normative) + +Let: + +```text +H(x) = Base58(SHA-256(RFC 8785 canonical JSON of x)) +``` + +BlueId is computed bottom-up over canonical BlueId Input using `H`. + +### 14.2 Context-sensitive cleaning and placeholder normalization (normative) + +Before hashing, implementations MUST normalize BlueId Input context-sensitively. + +#### Object-field cleaning + +For object fields: + +- remove fields whose value is `null`; +- remove fields whose value normalizes to an empty object `{}`; +- preserve fields whose value is an empty list `[]`; + +This removal is recursive and may cascade. + +#### List-element rules + +For list elements: + +- list elements MUST NOT be deleted merely because they are `null` or `{}`; +- in Source Documents, `null`, `{}`, and elements that recursively clean to empty objects MUST have been normalized to `$empty: true` before BlueId calculation; +- in BlueId Input, `null` and `{}` list elements are invalid; +- `[]` is preserved as an empty list element; +- `$empty: true` is preserved as placeholder content. + +This rule preserves list length, order, and positional meaning. + +In object-field context, an object that becomes empty after cleaning is omitted. In list-element context, a Source element that becomes empty after recursive cleaning is normalized to `$empty: true` before BlueId Input is produced. Direct BlueId Input MUST NOT contain raw empty-object list elements. + +#### Root normalization + +The root of BlueId Input is never omitted by cleaning. + +If the root is an empty object `{}`, its BlueId is `H({})`. + +If object-field cleaning causes the root object to become empty, the root remains `{}` and hashes as `H({})`. + +A root `null` value is not valid BlueId Input. Source Documents whose root is `null` MUST be rejected. Authors who intend an empty object document MUST write `{}`; authors who intend an empty list document MUST write `[]`. + +### 14.3 Canonical BlueId input normalization (normative) + +The BlueId algorithm hashes the abstract node model, not authoring syntax. + +Direct BlueId calculation does not run the full Source Document preprocessing pipeline. However, BlueId input normalization includes the mandatory primitive scalar inference needed to make bare scalar nodes identity-stable across conforming implementations. This inference is limited to the core primitive types listed below and does not apply aliases, imports, `blue` directives, or declared preprocessing transforms. + +Before hashing a Node value: + +- scalar sugar is normalized to scalar payload; +- list sugar is normalized to list payload; +- bare scalar payloads with no explicit type are assigned the corresponding core primitive type reference; +- integer values outside the safe JSON numeric integer range are represented as quoted canonical decimal text while retaining explicit `Integer` type (§2.4); +- finite `Double` values are converted to their canonical scalar representation; +- pure references are represented exactly as `{ blueId: X }`; +- `blue` is rejected; +- `$pos` is rejected; +- list `null` and empty-object elements are rejected unless already normalized to `$empty: true`. + +Primitive scalar inference for BlueId input normalization uses: + +| Parsed value kind | Inferred type | +|---|---| +| string | `Text` | +| integer numeric token with no decimal point or exponent, or explicitly typed canonical integer text | `Integer` | +| numeric token with a decimal point or exponent, or other non-integer finite number | `Double` | +| boolean | `Boolean` | + +A scalar payload with explicit type uses the explicit type, subject to resolution and validation. + +### 14.4 Scalars (normative) + +For BlueId calculation, every scalar payload node is normalized to a **typed scalar identity form** before hashing. If no explicit effective type is present, the inferred primitive type from §14.3 is inserted. Therefore an untyped Source scalar token `1` hashes as a scalar node with effective type `Integer`, while source tokens `1.0` and `1e0` hash as scalar nodes with effective type `Double`. The effective scalar type is part of identity. + +A bare scalar payload is represented as the canonical scalar value and, when converted to canonical BlueId input as a node, includes its inferred primitive type unless an explicit type is already present. + +Scalar values are encoded using RFC 8785 canonical JSON value rules after Blue scalar normalization. + +For `Integer`, implementations MUST preserve mathematical integer identity. Integer values outside the safe JSON numeric integer range MUST be encoded as canonical decimal text while retaining `type: Integer` in the canonical BlueId input (§2.4). + +For `Double`, only finite numbers are valid. `NaN`, `Infinity`, and `-Infinity` are invalid Blue scalar values. + +A `Double` value whose canonical JSON number renders as an integer-looking number, such as `1`, remains distinct from `Integer` because the canonical BlueId input retains `type: Double`. Numeric rendering alone does not determine scalar type after preprocessing. + +### 14.4.1 Payload normalization before hashing (normative) + +The BlueId algorithm hashes the abstract Blue node model, not raw JSON/YAML syntax. + +Before map hashing is applied, each node is classified as one of: + +1. pure reference; +2. scalar payload node; +3. list payload node; +4. object payload node; +5. metadata-bearing node. + +A node with a scalar payload and no retained metadata other than its effective scalar type and value hashes as the typed scalar identity form. "Payload-only scalar" does not mean hashing the raw JSON scalar alone; it means hashing the canonical Blue scalar node consisting of the effective primitive type reference and the canonical scalar value. If no explicit effective type is present, the inferred primitive type is inserted before hashing. + +A node with a list payload and no retained metadata other than the payload itself hashes as the list payload. + +Therefore these forms hash identically: + +```yaml +x: 1 +``` + +```yaml +x: + value: 1 +``` + +and these forms hash identically: + +```yaml +x: [a, b] +``` + +```yaml +x: + items: [a, b] +``` + +Thus these Source scalar tokens do not all have the same typed scalar identity unless an explicit type or schema says otherwise: + +```yaml +1 # effective type Integer, value 1 +1.0 # effective type Double, canonical numeric payload may render as 1 +1e0 # effective type Double, canonical numeric payload may render as 1 +``` + +`1.0` and `1e0` are equivalent Double values, but they are not equivalent to Integer `1` because the effective type differs. + +When a node has retained metadata such as `type`, `schema`, `name`, `description`, `itemType`, `mergePolicy`, or `contracts`, it hashes as a metadata-bearing map. In that case, `value` or `items` is the payload field of that metadata-bearing node and participates in map hashing as defined below. + +A node MUST NOT contain more than one payload kind. + +### 14.5 Map hashing (normative) + +Map hashing applies only after payload-only scalar and payload-only list nodes have been normalized as described above. + +If and only if a map is exactly: + +```json +{ "blueId": "" } +``` + +then its BlueId is ``. This is the pure reference short-circuit. + +A map containing `blueId` together with sibling fields is not a pure reference and MUST NOT appear in BlueId Input. + +Otherwise, build the helper map `M` conceptually. Its serialized property order is the order defined by RFC 8785 canonical JSON. Implementations MUST NOT use locale-sensitive collation or implementation insertion order. + +- for `name`, `description`, and `value`, inline their cleaned scalar values; +- for every other key `k` with value `v`, include: + +```json +"k": { "blueId": id(v) } +``` + +Then compute: + +```text +id(map) = H(M) +``` + +This rule ensures nested structure contributes through BlueId rather than through byte shape. It also makes materialized subtrees and pure references identity-equivalent when they have the same BlueId. + +### 14.6 Object fields with `null` (normative) + +Object fields with `null` values are omitted before map hashing: + +```yaml +a: null +b: 1 +``` + +normalizes as: + +```yaml +b: 1 +``` + +If recursive cleaning makes a child object empty, the child field is also omitted. Empty lists are preserved. + +### 14.7 List hashing (normative) + +Lists are hashed using a domain-separated streaming fold over element BlueIds. The fold is recursive over list prefixes: the identity after element `n` is calculated from the identity of the first `n-1` elements and the BlueId of element `n`. + +This section defines the exact algorithm. Implementations MUST hash the canonical helper objects shown below. They MUST NOT replace the helper objects with raw string concatenation of Base58 BlueIds or with an implementation-specific binary encoding. + +#### 14.7.1 Empty-list seed, fold step, and recursive prefix identity (normative) + +Define the empty-list seed: + +```text +L0 = id([]) = H({ "$list": "empty" }) +``` + +Define a fold step over two already established exact identities: + +```text +FOLD_LIST_ID(previousPrefixBlueId, elementBlueId) = + H({ + "$listCons": { + "prev": { "blueId": previousPrefixBlueId }, + "elem": { "blueId": elementBlueId } + } + }) +``` + +The helper object passed to `H` is serialized using RFC 8785. Its property order is therefore the RFC 8785 order, not the visual order of the pseudocode and not host-map insertion order. + +For a list: + +```text +[a1, a2, ..., an] +``` + +define each prefix identity recursively: + +```text +L0 = id([]) +L1 = FOLD_LIST_ID(L0, id(a1)) +L2 = FOLD_LIST_ID(L1, id(a2)) +... +Ln = FOLD_LIST_ID(Ln-1, id(an)) +``` + +Then: + +```text +id([a1, a2, ..., an]) = Ln +``` + +Equivalently: + +```text +id(prefix + [x]) = FOLD_LIST_ID(id(prefix), id(x)) +``` + +The value `Ln-1` is exactly the BlueId of the list prefix `[a1, ..., an-1]`; it is not a separate hidden list state. + +For each element, `id(ai)` is the element's BlueId after BlueId input normalization. If the element is a pure reference, the pure-reference short circuit supplies the referenced BlueId. If the same element is materialized and verifies to that BlueId, the fold input is identical. + +#### 14.7.2 Incremental append (normative) + +If both of the following are already established and valid: + +```text +P = id([a1, ..., an]) +X = id(x) +``` + +then the BlueId of the appended list is: + +```text +id([a1, ..., an, x]) = FOLD_LIST_ID(P, X) +``` + +The implementation does not need to materialize, enumerate, or rehash `a1, ..., an` merely to calculate the new list identity. It performs one additional list fold step after establishing the new element's BlueId. + +For `k` appended elements `b1, ..., bk`, the implementation performs `k` additional fold steps: + +```text +P0 = id(existingList) +P1 = FOLD_LIST_ID(P0, id(b1)) +P2 = FOLD_LIST_ID(P1, id(b2)) +... +Pk = FOLD_LIST_ID(Pk-1, id(bk)) +``` + +and `Pk` is the BlueId of the resulting list. + +This optimization is valid only when the prefix BlueId is already established and trusted as the exact identity of the prefix used by the operation. An implementation MUST NOT accept an arbitrary claimed prefix BlueId merely to avoid processing the prefix. A `$previous` anchor is one Source-level way to carry such a claim, but resolution MUST verify it under §11.7 before it may seed the fold. An implementation may also obtain the exact prefix identity from an admitted exact list node, a verified provider, or a previously established immutable processing state. + +The append property avoids rereading the old elements for identity calculation. It does not make calculation of the appended element's own BlueId free, and it does not eliminate the identity work required to rebuild a metadata-bearing list node or its changed ancestors (§14.7.5). + +#### 14.7.3 Replacement, insertion, and removal (normative) + +The list fold is prefix-dependent. Changing an element changes that prefix state and therefore changes every later fold state. + +For a replacement at zero-based index `i` in a list of length `n`: + +```text +[a0, ..., ai-1, ai, ai+1, ..., an-1] + -> +[a0, ..., ai-1, x, ai+1, ..., an-1] +``` + +an implementation may reuse the exact identity of the unchanged prefix: + +```text +Pi = id([a0, ..., ai-1]) +``` + +when that identity is available. It must then fold: + +```text +id(x), id(ai+1), ..., id(an-1) +``` + +to establish the new final list identity. Thus the required fold work is proportional to the suffix beginning at the first changed position, not necessarily to the complete list. + +Insertion and removal have the same property: every fold state at and after the first changed position must be recomputed. Appending is the special case in which the first changed position is after the existing final element, so none of the existing fold states must be recomputed. + +A final list BlueId alone does not reveal element BlueIds, intermediate prefix BlueIds, list length, or list contents. If those values are required for enumeration or arbitrary editing, they must be available from the materialized list, a provider, or other verified storage metadata. The BlueId algorithm defines identity; it is not a reversible list encoding. + +#### 14.7.4 Identity calculation versus physical storage (informative) + +The incremental append property places no required storage format on providers. + +A provider may store, for example: + +- the complete list node; +- a shallow list representation containing direct element BlueIds; +- chunks of element BlueIds; +- an append record containing the previous list BlueId and appended element BlueId; +- additional verified prefix-index metadata. + +Whatever representation is used, the logical list and its final BlueId must be the same. Physical storage, caches, prefix indexes, and batching are not Blue Language semantics. + +An implementation that retains only the final 32-byte digest cannot reconstruct the list from that digest. It must retain or obtain the content separately when content access is required. + +#### 14.7.5 Metadata-bearing list nodes (normative) + +The streaming fold establishes the identity of a list payload. A node that also carries list metadata hashes as a metadata-bearing map under §14.5. + +For example: + +```yaml +entries: + type: List + itemType: Timeline Entry + mergePolicy: append-only + items: + - A + - B + - C +``` + +is conceptually identified in two layers: + +```text +itemsBlueId = id([A, B, C]) + +entriesNodeBlueId = id({ + type: List, + itemType: Timeline Entry, + mergePolicy: append-only, + items: { blueId: itemsBlueId } +}) +``` + +The second line is conceptual notation for the map-hashing rule; the exact type and metadata values contribute through their BlueIds as specified by §14.5. + +Appending `D` may establish the new list-payload identity with one fold step: + +```text +newItemsBlueId = FOLD_LIST_ID(itemsBlueId, id(D)) +``` + +but the implementation must also establish the new identity of the metadata-bearing list node and every changed ancestor that contains it. It still does not need to materialize or rehash unchanged earlier elements merely to continue the list fold. + +#### 14.7.6 Worked calculation (informative) + +For: + +```yaml +- A +- B +- C +``` + +let: + +```text +AID = id(A) +BID = id(B) +CID = id(C) +``` + +Then: + +```text +L0 = H({ "$list": "empty" }) +L1 = FOLD_LIST_ID(L0, AID) = id([A]) +L2 = FOLD_LIST_ID(L1, BID) = id([A, B]) +L3 = FOLD_LIST_ID(L2, CID) = id([A, B, C]) +``` + +To append `D`, if `L3` and `DID = id(D)` are already established: + +```text +L4 = FOLD_LIST_ID(L3, DID) = id([A, B, C, D]) +``` + +Calculating `L4` does not require the contents of `A`, `B`, or `C`. It requires the exact previous-list BlueId `L3` and the exact new-element BlueId `DID`. + +The semantic properties of the algorithm are: + +- order is significant; +- multiplicity is preserved; +- lists are not flattened; +- `[A]` is distinct from `A`; +- `[]` is distinct from absent values and cleaned object fields; +- `[A, {$empty: true}, B]` is distinct from `[A, B]`; +- pure-reference and verified materialized elements contribute the same element BlueId; +- append identity calculation can continue from an established exact prefix BlueId; +- arbitrary edits require recomputation of the affected suffix. + +### 14.8 List control normalization before hashing (normative) + +For direct anchored BlueId Input: + +- `$previous` MAY appear only as the first item. +- If present and well-formed, `$previous.blueId` MAY seed the list fold. +- Anchor validity is a precondition of direct anchored BlueId Input. +- A Canonical Identity Input produced by the Source Document identity pipeline MUST NOT contain `$previous`. +- Implementations MAY use a verified prefix BlueId as an internal hashing optimization. + +`$pos` and `$replace` MUST NOT appear in BlueId Input. `$empty: true` remains content and hashes as a normal object element. + +Malformed list controls MUST be rejected. + +### 14.8.1 Canonical JSON examples (informative but behavior-defining through referenced rules) + +#### Large Integer scalar node + +An Integer outside the safe JSON numeric integer range is represented as quoted canonical decimal text with explicit Integer type. + +Canonical BlueId Input shape: + +```yaml +type: + blueId: +value: "9007199254740992" +``` + +Map hashing builds helper map `M` conceptually: + +```json +{ + "type": { "blueId": "" }, + "value": "9007199254740992" +} +``` + +The RFC 8785 canonical JSON byte sequence is the UTF-8 encoding of: + +```json +{"type":{"blueId":""},"value":"9007199254740992"} +``` + +#### Double negative zero + +`Double` values use finite IEEE 754 binary64 semantics. Negative zero and positive zero compare as the same numeric value. Under RFC 8785 canonical JSON, the numeric value canonicalizes as JSON number `0`. + +A Source token such as `-0.0` infers `Double` if no explicit type is provided, but the canonical scalar numeric payload is `0` and the effective `type: Double` preserves the fact that the node is a Double rather than an Integer. + +#### Integer-looking Double + +A Source token such as `1.0` or `1e0` infers `Double`. The canonical JSON representation of the numeric payload may render as `1`, but the effective `type: Double` remains part of canonical BlueId input. Therefore `1` as Integer and `1.0` as Double are distinct Blue values unless an explicit type or schema says otherwise. + +#### List fold helper map ordering + +The list fold step uses the exact object keys `$listCons`, `prev`, and `elem`: + +```json +{"$listCons":{"elem":{"blueId":""},"prev":{"blueId":""}}} +``` + +The example shows the RFC 8785 canonical JSON serialization for these keys. Implementations MUST NOT rely on insertion order or host map order. + +### 14.9 Storage rule (normative) + +A node MUST NOT store its own BlueId as authoritative content. + +Using `{ blueId: ... }` to reference other nodes is permitted and encouraged. A provider or envelope MAY store a node's BlueId out-of-band, but the self-BlueId MUST NOT be treated as part of the node's own content. + +### 14.10 Inputs containing `blue` (normative) + +BlueId Input MUST NOT contain `blue`. A direct hasher MUST reject such input. + +--- + +### 14.11 Identity locality and direct-container cost (normative) + +BlueId is transitive through direct child identities rather than transitive child bytes. Therefore establishing or verifying an object's identity requires its complete direct helper map and the BlueIds of its direct children, but not the bodies of those children. + +Consequences: + +- a large descendant behind one direct child BlueId does not need to be expanded to verify or rebuild its parent; +- changing one member of a direct object requires rebuilding that object's complete direct helper map; +- appending to a list may continue from a verified prior fold identity; +- replacing, inserting, or removing an early list element requires recomputing the affected suffix fold; +- one extremely wide flat object or positional list remains expensive under Language 1.0 even when represented by a pure reference. + +These costs are properties of the current identity algorithm, not of inline versus referenced representation. The inline and referenced forms of the same exact node require the same direct identity information for the same structural update. + +Language 1.0 does not define Merkle maps or random-access Merkle vectors. Applications needing logarithmic point updates or proofs SHOULD use bounded-fanout application structures. A future major Language version may standardize such collection identities. + +## 15. Circular Reference Sets + +### 15.1 Purpose + +Some authoring graphs contain direct cycles across documents, for example `Person` references `Dog` and `Dog` references `Person`. Blue supports a combined BlueId for a cyclic set, with stable per-document suffixes. + +### 15.2 ZERO_BLUEID sentinel (normative) + +During cyclic-set calculation, each direct cyclic reference is temporarily replaced with the **ZERO_BLUEID** sentinel: forty-four ASCII `0` characters. + +ZERO_BLUEID is a sentinel only. It MUST NOT appear in finalized BlueId Input. + +During cyclic-set calculation, ZERO_BLUEID and `this#` are permitted only in positions where a BlueId string is expected inside the temporary cyclic-set calculation input. + +They are not valid ordinary BlueId Input and MUST NOT appear in finalized provider-stored content. + +### 15.3 Cyclic-set input (normative) + +The input to the cyclic-set algorithm is a finite set of document roots plus explicit internal reference markers indicating which references point to documents within the set. + +The algorithm applies to a strongly connected cyclic set. Independent strongly connected components SHOULD be processed separately. + +A cyclic-set calculation input MUST contain at least one internal cyclic reference. A set with no internal cyclic references SHOULD be treated as ordinary independent documents rather than as a cyclic set. + +If two cyclic-set members have identical preliminary BlueIds, implementations MUST compare the RFC 8785 canonical JSON byte sequence of their preliminary BlueId input as a deterministic tie-breaker. + +If the tie remains equal, the cyclic-set input is invalid in Blue Language 1.0 unless the members contain an explicit identity-bearing disambiguator before preliminary hashing. Implementations MUST fail cyclic-set calculation with `CircularSetError` rather than assigning arbitrary positions. + +Blue Language 1.0 does not define graph-isomorphism rules for duplicate preliminary cyclic members. + +### 15.4 Cyclic-set algorithm (normative) + +Given a finite set of documents participating in a direct cycle: + +1. Temporarily replace each internal cyclic `blueId` reference with ZERO_BLUEID. +2. Calculate preliminary BlueIds for each document in isolation. +3. Sort documents lexicographically by preliminary BlueId, with the tie-breaking rule from §15.3. +4. Assign positions `#0` through `#(n-1)` according to that order. +5. Rewrite each internal cyclic reference as: + +```yaml +blueId: this# +``` + +where `` is the assigned position of the target document. + +6. Build a list: + +```text +L = [doc#0, doc#1, ..., doc#(n-1)] +``` + +with `this#` references in place. + +7. Compute: + +```text +MASTER = id(L) +``` + +8. The final BlueId of document `i` is: + +```text +MASTER#i +``` + +The **preliminary BlueId input** for each document is the document after replacing each direct internal cyclic `blueId` reference with ZERO_BLUEID and before rewriting those references to `this#`. + +`this#` is accepted only by the cyclic-set calculation API. It MUST NOT appear in stored provider content, ordinary BlueId Input, Source Documents outside explicit cyclic-set serialization, or Canonical Identity Input. + +During preliminary BlueId calculation with ZERO_BLUEID placeholders, a pure reference `{ blueId: ZERO_BLUEID }` is treated as a temporary pure reference whose identity contribution is the sentinel value for the purpose of preliminary ordering only. ZERO_BLUEID MUST NOT be returned as a finalized BlueId. + +During MASTER calculation, pure references `{ blueId: "this#" }` are treated as internal cyclic placeholders as defined by the cyclic-set algorithm, not as ordinary provider references. + +Cyclic-set identity flow: + +```text +authoring refs + | + v +replace internal refs with ZERO_BLUEID + | + v +preliminary ids -> sort -> assign #0..#(n-1) + | + v +rewrite internal refs to this#k + | + v +MASTER = id([doc#0, doc#1, ...]) + | + v +final ids = MASTER#0, MASTER#1, ... +``` + +### 15.5 BlueId grammar for cyclic sets (normative) + +A cyclic-set member BlueId has the form: + +```text +# +``` + +where `MASTER` is a plain BlueId and `index` is a non-negative decimal integer with no leading zeros, except for the single digit `0`. + +`this#` is an algorithm-internal placeholder. It is accepted only by an implementation API explicitly performing cyclic-set calculation over a declared finite cyclic set. It MUST be rejected by ordinary parsing, preprocessing, resolution, provider storage, expansion, canonicalization, and direct BlueId calculation outside that cyclic-set calculation API. + +### 15.6 Example (informative) + +```yaml +# Dog (#0 after sorting) +name: Dog +owner: + type: + blueId: this#1 +breed: + type: Text + +# Person (#1 after sorting) +name: Person +pet: + type: + blueId: this#0 +``` + +If `MASTER = 12345...`, then: + +```text +Dog = 12345...#0 +Person = 12345...#1 +``` + +--- + +## 16. Conformance Vectors + +The Blue Language 1.0 conformance suite, canonical core registry, and this prose specification jointly define Blue Language 1.0. The prose rules are normative, the registry supplies exact identity-bearing core type nodes and BlueIds, and the fixtures provide behavior-defining executable examples. + +A fixture package identity MUST be published with the Blue Language 1.0 release. A conforming implementation MUST report which fixture package identity it passes. + +If the prose specification, registry, and fixture package conflict, the release artifact is invalid and MUST be corrected. Implementations MUST NOT guess which artifact wins. + +Conformance vectors are behavior-defining. A conforming Blue Language 1.0 implementation MUST pass all vectors in this section and all machine-readable fixtures in the Blue Language 1.0 conformance suite. + +The labels `B`, `R`, and `F` identify fixture categories: BlueId algorithm, resolution/canonicalization, and provider/full-graph behavior. They do not define separate conformance levels. + +### 16.1 BlueId algorithm vectors + +- **B1.** `id([])` is defined and distinct from absent values and cleaned object fields. +- **B2.** `[A]` hashes differently from `A`. +- **B3.** `[[A, B], C]` hashes differently from `[A, B, C]`. +- **B4.** `x: 1` and `x: { value: 1 }` produce the same BlueId after canonical input normalization. +- **B5.** `x: [a, b]` and `x: { items: [a, b] }` produce the same BlueId. +- **B6.** A map exactly `{ blueId: X }` hashes to `X`. +- **B7.** Object-field cleaning removes `null` fields and fields that normalize to empty objects. +- **B8.** Cleaning preserves `[]`. +- **B9.** A node containing `blue` is rejected as direct BlueId Input. +- **B10.** A map mixing `blueId` with sibling fields is rejected as BlueId Input. +- **B11.** Primitive scalar inference assigns `Text`, `Integer`, `Double`, and `Boolean` deterministically. +- **B12.** `$empty: true` remains content and affects BlueId. +- **B13.** Direct BlueId Input containing a `null` list element is rejected. +- **B14.** Direct BlueId Input containing an empty-object list element is rejected unless it has already been normalized to `$empty: true` before direct hashing. +- **B15.** `[A, {$empty: true}, B]` hashes differently from `[A, B]`. +- **B16.** Integer values above `9007199254740991` or below `-9007199254740991` are represented as quoted canonical decimal text with explicit `Integer` type. +- **B17.** `this#` is rejected outside the explicit cyclic-set calculation API. +- **B18.** A source numeric token `1` infers `Integer`; source numeric tokens `1.0` and `1e0` infer `Double`; explicit `type: Double` remains Double even when the canonical JSON number renders as `1`. +- **B19.** Root `{}` is valid BlueId Input and hashes as an empty object; it is not omitted. +- **B20.** Root `null` is invalid as Source Document root and as BlueId Input. +- **B21.** Plain BlueIds validate as canonical Base58 encodings of exactly 32 bytes; invalid alphabet characters, non-canonical encodings, wrong decoded length, and plain ID strings containing `#` are rejected. +- **B22.** `$empty` list placeholder shape is exactly `{ "$empty": true }`; malformed `$empty` items are rejected. +- **B23.** `Double` negative zero canonicalizes to numeric payload `0` while retaining Double type. +- **B24.** `Double` overflow is rejected. +- **B25.** Integer-looking Double canonical rendering retains Double type. +- **B26.** Payload-only scalar hashing uses typed scalar identity form, not raw JSON scalar hashing. +- **B27.** Enum order and duplicate entries do not affect effective canonical schema identity. +- **B28.** `Double` `multipleOf` is evaluated by exact rational arithmetic over IEEE 754 binary64 values. +- **B29.** A cyclic-set input with duplicate preliminary member inputs fails unless the members contain identity-bearing disambiguators before preliminary hashing. +- **B30.** A fully materialized node and its direct-node materialization pattern have the same BlueId. +- **B31.** Replacing a direct child by a pure reference to that child preserves the parent BlueId. + +### 16.2 Resolution and canonicalization vectors + +- **R1.** Preprocessing removes `blue` and applies baseline transforms before resolution. +- **R2.** Source list `[A, null, B]` preprocesses to `[A, {$empty: true}, B]`, not `[A, B]`. +- **R3.** Source list `[A, {}, B]` preprocesses to `[A, {$empty: true}, B]`, not `[A, B]`. +- **R4.** Type chains merge according to the overlay and subtyping rules. +- **R5.** Fixed-value invariants cannot be overridden. +- **R6.** Schema constraints accumulate; irreconcilable constraints fail resolution. +- **R7.** Schema objects containing keys outside §9.2 are rejected. +- **R8.** `name` and `description` are ignored by matchers and subtype checks. +- **R9.** Type root `name` and `description` are not inherited onto the instance root. +- **R10.** A Source Document and its Resolved Form, after canonicalization, derive the same BlueId. +- **R11.** Requirement overlays bind valid type completions and reject conflicting completions. +- **R12.** `$previous` is validated against the resolved inherited prefix; mismatch fails resolution. +- **R13.** `mergePolicy` defaults to `positional` only when there is no inherited effective `mergePolicy`. +- **R14.** Append-only lists reject `$pos`. +- **R15.** Positional lists reject inherited-prefix reordering and removal. +- **R16.** A Minimized Overlay re-resolves to the same Resolved Form. +- **R17.** Canonical Identity Input does not contain `$previous`, `$pos`, `blue`, unresolved aliases, `null` list elements, or empty-object list elements. +- **R18.** Direct hashing of a Resolved Form is not used as the Source Document's BlueId unless the Resolved Form is already identical to its Canonical Identity Input. +- **R19.** Canonical Identity Input for append-only lists does not serialize `$previous`; `$previous` may appear only in Minimized Overlay or direct anchored BlueId Input. +- **R20.** Canonical Identity Input contains no type aliases; all type references are canonical BlueId references. +- **R21.** A source pure reference that is materialized only for resolution canonicalizes back to the pure reference unless the source overlays additional instance content onto it. +- **R22.** A child overlay of an inherited `append-only` list that omits `mergePolicy` remains `append-only`; `$pos` is still rejected. +- **R23.** A descendant collection that omits inherited `itemType`, `keyType`, or `valueType` retains the inherited constraint. +- **R24.** Canonical positional list refinements produce final canonical list payloads, not Source overlay instructions. +- **R25.** Minimized positional list overlays may use `$pos` and re-resolve to the same Resolved Form. +- **R26.** Canonical append-only list overlays do not contain `$previous`; minimized append-only overlays may use `$previous`. +- **R27.** Inherited effective Integer type accepts quoted canonical large decimal text. +- **R28.** Quoted decimal text without effective Integer type remains Text. +- **R29.** Inherited effective Integer type rejects non-canonical decimal text. +- **R30.** Declaration-only label overrides are allowed, but label overrides on inherited fixed-value nodes are rejected. +- **R31.** Type-chain cycles and self-type cycles are rejected. +- **R32.** Required metadata-only fields fail, while required instance payloads and inherited fixed payloads pass. +- **R33.** `minFields` and `maxFields` count ordinary fields only. +- **R34.** Wrong-kind schema keywords fail schema validation. +- **R35.** `itemType`, `keyType`, and `valueType` validate resolved collection members. +- **R36.** Direct Dictionary integer keys use canonical textual form and reject duplicate key conflicts after canonicalization. +- **R37.** Source list `[A, { x: null }, B]` preprocesses to `[A, { $empty: true }, B]`. +- **R38.** Canonical core type compatibility is nominal by registry BlueId. +- **R39.** Blue Language operation path root is the empty string under RFC 6901; `/` selects the empty-key member. +- **R40.** Limited resolution of a demanded path yields the same value, effective type, and applicable constraints as complete resolution. +- **R41.** A limited resolver never reports an unexpanded or unresolved field as absent merely because a limit prevented access. +- **R42.** An incomplete limited result is rejected as input to whole-node canonicalization, Source Document BlueId calculation, and minimization. +- **R43.** A limit, unexpanded reference, or unavailable provider resource never produces a successful `Absent` result. +- **R44.** Semantic lookup through a pure reference is transparent: a collapsed wrapper does not create a semantic child named `blueId`. +- **R45.** A demand-limited exact-node-identity request returns the same BlueId for inline, collapsed, and partially expanded forms. +- **R46.** A pure reference used as `schema` or `contracts` is semantically equivalent to its verified materialization; operations expand it only when its contents are demanded. +- **R47.** A source pure reference used for `schema` or `contracts`, when materialized only for resolution or validation, is preserved as the source pure reference by canonicalization unless a non-derivable instance overlay must be represented. +- **R48.** Omitting `blue` still applies the complete mandatory baseline preprocessing algorithm. +- **R49.** An empty inline `blue` directive and an omitted directive produce the same Preprocessed Document. +- **R50.** An inline preprocessing directive and a pure reference to that exact directive produce the same Preprocessed Document. +- **R51.** A referenced directive, imports object, transformations list, or transformation item is used only after exact provider verification; invalid evidence fails. +- **R52.** Declared transformations execute exactly once each in declared list order, and each transformation receives the prior transformation's complete output. +- **R53.** Transformations execute before automatic alias substitution and primitive inference; mandatory baseline preprocessing normalizes transformation output afterward. +- **R54.** When one directive contains both `imports` and `transformations`, the import map is established before execution, transformations execute first, and remaining aliases are substituted afterward. +- **R55.** `blue.imports` substitutes aliases only in `type`, `itemType`, `keyType`, and `valueType` positions; identical ordinary Text values remain data. +- **R56.** A transformation item may be inline or a verified pure reference without changing the preprocessing result. +- **R57.** `imports` and `transformations` may themselves be verified reference-backed exact nodes. +- **R58.** An unsupported required transformation causes deterministic `UnsupportedPreprocessingTransform` failure and is never ignored. +- **R59.** A transformation that introduces `blue` at any path fails preprocessing. +- **R60.** A string-valued directive alias resolves to one exact directive BlueId under the declared preprocessing environment; an unbound alias fails. +- **R61.** A built-in alias may be repeated only with its canonical BlueId; rebinding it to a different BlueId fails. +- **R62.** `blue` is valid only at the Source Document root; nested directives fail. +- **R63.** Preprocessing is idempotent for an already valid Preprocessed Document. +- **R64.** An unused import does not change the Preprocessed Document or Source-derived BlueId. +- **R65.** Blue Language 1.0 defines no `blue.profile` wrapper; reusable directives use `blue: { blueId: X }` directly. +- **R66.** The portable transformation list is declared by `blue.transformations`; a legacy `blue.items` list-payload directive is invalid. +- **R67.** A portable transformation's type must be exact and cannot depend on Source-document import alias substitution. +- **R68.** Expansion of a verified existing node preserves that node's BlueId, while specialization through `type` and compatible overlay content creates a new node and normally a different BlueId. +- **R69.** The Source Document identity pipeline is `preprocess -> complete resolve -> canonicalize -> BlueId`; minimization is not a step in that pipeline. +- **R70.** The BlueId derived from a Source Document is exactly the BlueId of its unique Canonical Identity Input. +- **R71.** Directly hashing a Source Document, noncanonical Resolved Form, or Minimized Overlay MUST NOT be assumed to produce the Source Document's BlueId. +- **R72.** For an inherited append-only list, canonicalization produces the final ordinary list payload, while minimization may use a valid `$previous` overlay; both derive the same BlueId only through the complete Source Document identity pipeline. +- **R73.** For an inherited positional list, canonicalization produces the final ordinary list payload, while minimization may use `$pos` or `$replace`; both derive the same BlueId only through the complete Source Document identity pipeline. + +### 16.3 Provider, expansion, and collapse vectors + +- **F1.** All B-vectors and R-vectors pass. +- **F2.** Expansion preserves BlueId. +- **F3.** If the implementation exposes collapse, collapse preserves BlueId and produces only valid pure references. +- **F4.** Expansion supports configurable depth or path limits that do not affect identity. +- **F4a.** A document root supplied as `{ blueId: X }` can be expanded only at demanded paths without recursively materializing all descendants. +- **F4b.** Inline and verified referenced forms produce identical demanded expansion and resolution results. +- **F5.** Cross-document references resolve through a provider without changing identity. +- **F6.** Missing provider content required for resolution fails deterministically. +- **F7.** Ordinary BlueId provider content whose computed BlueId does not equal the requested BlueId is rejected. +- **F8.** Source Document provider content requires a declared Source Document provider mode and Source Document BlueId verification. +- **F9.** Cyclic-set member provider content requires cyclic-set-aware verification context. +- **F16.** An exact direct-fragment graph reconstructs the original Root and preserves every Root BlueId. +- **F17.** Fragment identity order and provider results are deterministic and defensive. +- **F18.** A finalized `MASTER#index` edge is preserved opaquely; the ordinary fragment provider does not claim member content. +- **F19.** A cyclic-aware provider can open an opaque member only with complete owning-set proof. +- **F10.** One materialized object node can be verified from its complete direct keys, inline identity scalars, and child BlueIds without fetching child bodies. +- **F11.** One materialized list node can be verified from its ordered element BlueIds without fetching element bodies. +- **F11a.** Provider-internal append anchors or prefix folds do not replace the complete ordered direct element identities needed to reconstruct a requested direct list node. +- **F12.** Expanding one node while leaving complete direct children collapsed, and then collapsing the selected node again, preserves the exact root BlueId and does not demand descendant bodies that were never selected. +- **F13.** Demanding `/a/b/c` from a direct-node provider requires only the root and the direct nodes on that path, unless type or schema semantics demand additional nodes. +- **F14.** Provider batching, prefetching, and cache state do not change semantic results. +- **F15.** A provider that omits a demanded direct key cannot report absence unless the complete direct manifest has been verified. + +### 16.4 Machine-readable fixtures (normative) + +The Blue Language 1.0 conformance suite MUST publish machine-readable fixtures with exact expected BlueIds. + +The canonical fixture package is part of the Blue Language 1.0 conformance release and is versioned with this specification.

Exact expected BlueIds are defined by the machine-readable fixture suite (§16.4). + +### 17.1 Content-addressable types (informative) + +```yaml +name: Simple Amount +amount: + type: Double +currency: + type: Text +# => blueId: FgHZjS... + +name: Person +age: + type: Integer +spent: + type: + blueId: FgHZjS... # Simple Amount +# => blueId: GRwTYs... +``` + +Instance: + +```yaml +name: Alice +type: + blueId: GRwTYs... # Person +age: 25 +spent: + amount: 27.15 + currency: USD +# => Source-derived BlueId: 3JTd8s... +``` + +Expanding the demanded type links makes the existing type nodes available without changing their BlueIds. The instance itself is a specialization: it uses `Person` as its type and supplies more specific content, so it is a new node. Resolving produces the complete semantic values. Complete resolution followed by canonicalization produces a Canonical Identity Input whose BlueId is the Source-derived BlueId of the instance. + +### 17.2 `blue` directive (informative) + +A document may declare imports and ordered transformations inline: + +```yaml +blue: + imports: + Ticket: + blueId: + DateTime: + blueId: + transformations: + - type: + blueId: + mappings: + Ticket Serial No.: ticketSerial + Departure: departure + - type: + blueId: + path: /departure + pattern: yyyy-MM-dd HH:mm + +type: Ticket +Ticket Serial No.: HL-923554 +Departure: 2025-03-27 15:25 +``` + +The processor first resolves and verifies the directive, imports, and transformation nodes. It removes `blue`, applies the rename transformation, then applies the DateTime transformation. Only after both transformations finish does mandatory baseline preprocessing replace `Ticket` and `DateTime` aliases, normalize wrappers and placeholders, and infer types for bare primitive values. + +The same complete directive can be stored as an exact Blue node and collapsed in the Source Document: + +```yaml +blue: + blueId: + +type: Ticket +Ticket Serial No.: HL-923554 +Departure: 2025-03-27 15:25 +``` + +When the referenced directive verifies to the inline directive above, both Source Documents preprocess identically. Blue Language 1.0 defines no separate `blue.profile` wrapper. + +### 17.3 Large integer (informative) + +```yaml +accountId: + type: Integer + value: "9007199254740992" +``` + +The value is quoted because it is outside the safe JSON numeric integer range. The explicit `Integer` type distinguishes it from Text. + +Numeric token inference: + +```yaml +a: 1 # inferred Integer +b: 1.0 # inferred Double +c: 1e0 # inferred Double +d: + type: Double + value: 1 +``` + +`b`, `c`, and `d` are Double values even when their canonical JSON number renders as `1`. + +### 17.4 Same image, different meaning (informative) + +```yaml +# A +name: Person to Avoid +description: This guy will kill you today +type: Image +image: + blueId: 123...456 + +# B +name: Family Member +description: Trust this person +type: Image +image: + blueId: 123...456 +``` + +These derive different BlueIds because `name` and `description` are identity content. Structural and type matchers ignore those labels. + +### 17.5 Requirement overlay followed by type binding (informative) + +```yaml +# Parent +name: A +prop1: + x: 1 + +# Child +name: B +type: A +prop1: + type: Some +``` + +The child is valid only if `Some` can resolve while preserving `x = 1`. If `Some` forces `x = 2`, resolution fails. + +### 17.6 Lists: refine and append (informative) + +```yaml +# Parent +name: Trip +segments: + type: List + itemType: Flight Segment + items: + - type: Flight Segment + carrier: BA + +# Child +name: Trip LHR to SFO +type: Trip +segments: + items: + - $pos: 0 + from: LHR + to: JFK + - type: Flight Segment + carrier: BA + from: JFK + to: SFO +``` + +The child refines inherited index `0` and appends a second segment. Reordering or deleting the inherited prefix would be invalid. + +### 17.7 Null list element as placeholder (informative) + +```yaml +items: + - A + - null + - B +``` + +preprocesses to: + +```yaml +items: + - A + - $empty: true + - B +``` + +It does not preprocess to `[A, B]`. + +### 17.8 Expansion with limits (informative) + +Starting from: + +```yaml +blueId: 3JTd8s... # Alice +``` + +expanding `/spent` may hydrate only the `spent` subtree: + +```yaml +name: Alice +type: + blueId: GRwTYs... +age: 25 +spent: + amount: 27.15 + currency: USD +``` + +BlueId is unchanged if the hydrated content verifies to the referenced BlueIds. + +### 17.9 Canonicalization and minimization (informative) + +From a complete Resolved Form with the type content required for identity, canonicalization: + +- represents type objects by exact references where required; +- removes structure fully derivable from the type chain; +- consumes `$pos`, `$replace`, and `$previous` controls; +- normalizes list placeholders to `$empty: true`; +- keeps non-derivable instance contributions; +- produces one valid BlueId Input. + +Consider an inherited append-only list `[A, B]` with `C` appended. A Minimized Overlay may say only: + +```yaml +items: + - $previous: + blueId: + - C +``` + +The Canonical Identity Input contains the final payload: + +```yaml +items: + - A + - B + - C +``` + +The first is convenient authoring compression. The second is the unique identity input. The Source-derived BlueId is calculated from the second. The minimized form reaches the same BlueId only after it is processed through preprocessing, complete resolution, canonicalization, and the BlueId algorithm again. + +### 17.10 Contracts merge as content (informative) + +```yaml +# Parent type +name: With Audit +contracts: + audit: + type: Audit Contract + enabled: true + +# Child instance +type: With Audit +contracts: + audit: + retentionDays: 30 +``` + +Language resolution merges `contracts.audit` as content. It does not execute the contract. The resolved contract entry contains both `enabled: true` and `retentionDays: 30`, unless normal fixed-value, type, or schema rules reject the merge. + +### 17.11 Incremental list BlueId calculation (informative) + +Blue list identity is a hash chain over exact element BlueIds. + +For the list: + +```yaml +items: + - A + - B + - C +``` + +the processor calculates: + +```text +L0 = id([]) +L1 = fold(L0, id(A)) = id([A]) +L2 = fold(L1, id(B)) = id([A, B]) +L3 = fold(L2, id(C)) = id([A, B, C]) +``` + +If `D` is appended and `L3` is already known: + +```text +L4 = fold(L3, id(D)) = id([A, B, C, D]) +``` + +The existing elements do not need to be expanded or rehashed for that append. By contrast, replacing `B` requires a new `L2` and then a new `L3`; every fold step after the first changed position is recalculated. + +For the exact domain-separated helper objects and the distinction between payload identity, metadata-bearing list-node identity, and storage, see §14.7. + +### 17.12 Common invalid forms (informative) + +Mixed reference and content is invalid: + +```yaml +blueId: X +name: Not allowed +``` + +`blue` is root-only and preprocessing-only: + +```yaml +child: + blue: something +``` + +`$pos` cannot appear in Canonical Identity Input or BlueId Input: + +```yaml +items: + - $pos: 0 + value: A +``` + +Use `$replace` for non-scalar positional replacement: + +```yaml +# Invalid +- $pos: 0 + value: + items: [A, B] + +# Valid +- $pos: 0 + $replace: + items: [A, B] +``` + +--- + +## Appendix A — Core Primitive and Collection Types + +Appendix A defines the canonical primitive and collection types referenced throughout this specification. + +The nodes in §A.1 are canonical type definitions, not illustrative sketches. Their `description` fields are normative, identity-bearing Blue content. The exact registry files used to calculate published BlueIds MUST be byte/string equivalent after Blue parsing to the intended canonical nodes. + +The core registry nodes in this appendix are the canonical Blue Language 1.0 primitive and collection definitions. Their `1.0` wording is identity-bearing content and agrees with this first public-version specification. The exact registry files—not retyped copies in implementation code—are authoritative for their published BlueIds. + +The execution environment selects Blue Language 1.0; the exact core-type BlueIds select the primitive meanings. After publication, an existing core-type BlueId may receive only errata outside the node. Changing identity-bearing semantics requires a new type identity. + +Changing a canonical node's `description` is a type-identity change. Implementations MUST NOT silently update canonical descriptions while keeping the old BlueId. + +If a typo or editorial issue is found after publication and it does not change semantics, publish errata outside the canonical node. If the text change is intended to alter or clarify the type's meaning in an identity-bearing way, publish a new registry entry with a new BlueId. + +### A.1 Canonical core type nodes + +#### Text + +```yaml +name: Text +description: > + Core Blue Language 1.0 primitive scalar representing Unicode text. Text + values are exact Unicode code-point sequences after parsing. Blue Language + performs no Unicode normalization, case folding, locale-sensitive collation, + whitespace normalization, or line-ending normalization by default. String + schema constraints minLength and maxLength count Unicode code points. The + empty string is valid unless restricted by schema. Applicable schema + constraints are minLength, maxLength, and enum. +``` + +#### Integer + +```yaml +name: Integer +description: > + Core Blue Language 1.0 primitive scalar for exact mathematical integer + values. Integer values are arbitrary precision in the language model. + Unquoted integer tokens are portable only in the safe JSON numeric integer + range [-9007199254740991, 9007199254740991]. Integer values outside that + range are represented as quoted canonical decimal text with explicit or + inherited effective Integer type. The canonical decimal text form uses an + optional leading minus sign followed by decimal digits, with no leading + zeros except the single digit zero. Applicable schema constraints are + minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, and enum. +``` + +#### Double + +```yaml +name: Double +description: > + Core Blue Language 1.0 primitive scalar for finite IEEE 754 binary64 + floating-point values. NaN, positive Infinity, and negative Infinity are + invalid Blue values. Double parsing uses round-to-nearest, ties-to-even + binary64 semantics; numeric tokens that overflow to Infinity or parse as NaN + are invalid. Source numeric tokens with a decimal point or exponent infer + Double when no explicit type is provided, even when their mathematical value + is integral. Negative zero and positive zero compare as the same numeric + value and canonicalize as JSON number zero, while the effective Double type + remains part of canonical BlueId input. Applicable schema constraints are + minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, and enum. +``` + +#### Boolean + +```yaml +name: Boolean +description: > + Core Blue Language 1.0 primitive scalar with exactly two values: true and + false. Blue Language defines no truthiness conversion for Boolean values. + Only the literal parsed boolean values true and false are Boolean values. + Applicable schema constraint is enum. +``` + +#### Dictionary + +```yaml +name: Dictionary +description: > + Core Blue Language 1.0 object-map collection type. A Dictionary is encoded + as a Blue object node whose ordinary child fields represent direct keys + when those keys do not collide with reserved language fields. Direct object + encoding cannot represent data keys named name, description, type, itemType, + keyType, valueType, value, items, blueId, blue, schema, mergePolicy, + contracts, properties, or constraints. Direct object encoding cannot + represent reserved language keys as data keys. Applications needing + arbitrary keys use an escaped entry representation such as a list of { key, + val } entries. keyType is optional; if + omitted and no effective keyType is inherited, keys default to Text for + direct object encoding. For direct object encoding, keyType must resolve to + a scalar key type with a canonical textual form, such as Text, Integer, + Double, or Boolean. valueType is optional; if omitted and no effective + valueType is inherited, values may be any Blue node. Applicable schema + constraints are minFields and maxFields. +``` + +#### List + +```yaml +name: List +description: > + Core Blue Language 1.0 ordered collection type. Surface array form and + wrapped items form are equivalent authoring forms. Order and multiplicity + are preserved. List BlueId calculation uses a domain-separated streaming + fold over element BlueIds. itemType is optional; if omitted and no effective + itemType is inherited, elements are not constrained by itemType. If + mergePolicy is omitted and no effective mergePolicy is inherited, resolvers + assume positional. append-only forbids changes to the inherited prefix. + positional allows $pos overlays within the inherited prefix. $previous, + $pos, $replace, and $empty are recognized only at the top level of items + when the node's effective type is List. Source list null and empty object + elements normalize to $empty: true and are not deleted. Applicable schema + constraints are minItems, maxItems, and uniqueItems. +``` + +### A.2 Editorial and registry rules + +The canonical registry nodes above are the Blue Language 1.0 core type nodes, retaining their established exact content and BlueIds. Their registry manifest is published under the Language 1.0 release and MUST be fixture-verified together with this specification. Non-normative examples, tutorials, rationale, translations, and implementation notes are not part of the canonical type nodes unless intentionally included in the registry entries. + +Additional explanatory documentation MAY follow this appendix or appear in separate registry documentation, but it MUST be clearly marked non-canonical unless it is included in the registry node itself. + +--- + +## Appendix B — Reserved Extension Boundary + +`contracts` is reserved for the Blue Contracts and Processor Specification 1.0. Blue Language 1.0 treats it as identity-bearing content only. See §4.4. + +--- + +## Appendix C — Common Implementer Mistakes + +This appendix is informative. + +### C.1 Do not delete list positions + +`[A, null, B]` does not mean `[A, B]`. Source list `null` and `{}` elements normalize to `$empty: true`. + +### C.2 Do not hash `blue` + +`blue` is a preprocessing directive. Direct BlueId input containing `blue` must be rejected. + +### C.3 Do not treat `value` as a generic replacement field + +`value` is the scalar payload wrapper. Positional non-scalar replacement uses `$replace`. + +### C.4 Do not let `$pos` reach BlueId input + +`$pos` is an overlay instruction. Canonical Identity Input and direct BlueId Input must not contain `$pos`. + +### C.5 Do not trust provider content without verification + +When expanding `blueId: X` through an ordinary BlueId provider, compute the returned content's BlueId and verify that it equals `X`. + +### C.6 Do not treat `name` and `description` as comments + +They affect BlueId. They are ignored by matchers, not by identity. + +### C.7 Use only the schema keywords defined in §9 + +A `schema` object accepts only the keywords listed in §9.2. + +### C.8 Do not use reserved language keys as ordinary object fields + +Reserved keys such as `type`, `value`, `items`, and `schema` have language meaning. + +--- + +### C.9 Do not expose the pure-reference wrapper as semantic content + +A semantic graph lookup must treat `{ blueId: X }` as node `X`, not as an application object containing a data field named `blueId`. + +### C.10 Do not let physical representation change semantic results + +Cache hits, provider pages, network bytes, batching, and host allocations are not Blue content. They must not change a Language operation's established, absent, incomplete, or invalid outcome. + +### C.11 Do not confuse expansion with specialization + +Expansion reveals more of an existing exact node and preserves its BlueId. Specialization creates a new node through `type` and compatible overlay content and normally creates a new BlueId. + +### C.12 Do not minimize before hashing + +Minimization is optional authoring compression. A Source Document's BlueId is calculated by complete resolution, canonicalization, and the BlueId algorithm. Directly hashing a Minimized Overlay does not establish that Source-derived BlueId. + +### C.13 Do not confuse semantic canonicalization with JSON serialization + +Blue semantic canonicalization derives the Canonical Identity Input. RFC 8785 canonical JSON is used later inside the BlueId algorithm. JSON key sorting alone is not Blue semantic canonicalization. + +### C.14 Do not require transitive expansion to verify a direct node + +The existing map and list BlueId algorithms verify one direct node from direct child identities. Fetching all descendants is unnecessary. + +### C.15 Do not confuse incremental list identity with reversible storage + +Appending to an exact list can calculate the new BlueId from the previous list BlueId and the appended element BlueId. This does not mean the final BlueId contains or can reconstruct the previous elements. Providers must retain or obtain list content separately when enumeration or arbitrary editing is required. Replacing, inserting, or removing an earlier element requires recomputing the affected fold suffix. + +## Appendix D — Error Categories + +This appendix is normative for conformance diagnostics but does not require a particular exception class, wire format, or exact error message. + +When an operation fails deterministically, implementations MUST be able to classify the failure into one of these categories for conformance reporting: + +| Category | Meaning | +|---|---| +| `InvalidSyntax` | Serialized JSON/YAML is malformed or outside the Blue JSON data model. | +| `DuplicateKey` | A serialized object contains duplicate keys. | +| `InvalidReservedField` | A reserved field has an invalid type, shape, or position. | +| `InvalidBlueId` | A BlueId string is malformed or invalid for its context. | +| `InvalidReferenceShape` | `blueId` appears with sibling fields or invalid mixed reference shape. | +| `InvalidBlueIdInput` | Direct BlueId received a node that is not valid BlueId Input. | +| `ProviderUnavailable` | Required provider content is unavailable. | +| `ProviderBlueIdMismatch` | Provider content does not verify against the requested BlueId. | +| `OperationIncomplete` | A demanded semantic result could not be established because required content or coverage was not available. | +| `OperationLimitExceeded` | An out-of-band operation limit prevented completion of a demanded result. | +| `TypeCycle` | Resolution detected a type-cycle in the active type stack. | +| `FixedValueConflict` | A descendant attempted to override or contradict an inherited fixed value. | +| `TypeCompatibilityViolation` | A descendant type, itemType, keyType, or valueType is incompatible with an inherited constraint. | +| `SchemaVocabularyError` | A schema contains an unknown keyword or invalid schema value shape. | +| `SchemaViolation` | A node violates accumulated schema constraints. | +| `ListControlViolation` | `$previous`, `$pos`, `$replace`, or `$empty` has invalid shape or context. | +| `CanonicalizationError` | A Canonical Identity Input cannot be produced deterministically. | +| `CircularSetError` | Cyclic-set input is malformed or cannot produce deterministic member IDs. | +| `UnsupportedPreprocessingTransform` | A Source Document requires a preprocessing transform that is unsupported. | + +An invalid document may contain multiple independent errors. Blue Language 1.0 does not require a universal precedence order for all possible simultaneous failures. Conformance fixtures that assert an exact error category MUST isolate one primary error so that a conforming implementation can deterministically report that category without ambiguity. If a fixture intentionally contains multiple independent errors, it MUST assert only that the operation fails, or it MUST explicitly declare acceptable error categories. + +--- + +## Appendix E — Informative Direct-Node Storage Guidance + +This appendix is informative. It does not add a separate Language conformance mode. + +### E.1 Admission + +A provider optimized for lazy graph access may normalize and verify a node, establish every direct child BlueId, and store one direct-node representation whose complete children are collapsed, keyed by the node's own BlueId. + +### E.2 Retrieval + +Retrieval of one BlueId should return enough direct content to verify that exact node without requiring descendant bodies. A provider may batch additional verified nodes, but batching is prefetch rather than semantics. + +### E.3 Path navigation + +A caller can verify the current direct node, select the direct child identity for the next path segment, fetch that child, and repeat. Type resolution or schema validation may demand additional nodes beyond the structural path. + +### E.4 Direct-node limitation + +A directly materialized node still contains its complete direct manifest and inline identity-bearing text. Very wide containers and very large direct scalars therefore remain unsuitable as fine-grained mutable structures. Chunking is the recommended Language 1.0 authoring pattern. + +### E.5 Provider chains + +Provider implementations should distinguish definitive `NotFound`, transient `Unavailable`, and deterministic `InvalidEvidence`. None of these outcomes is semantic path absence without the Language operation proving absence from sufficient graph content. + +### E.6 Exact graph fragments + +An exact graph fragment is ordinary Blue content. A fragment materializes one exact node while replacing any complete direct child with a pure reference to that child's exact BlueId. It is not a partial-node identity, cursor language, or fifth Language operation. + +A portable fragment utility SHOULD: + +- accept one or more exact Root nodes; +- calculate and verify every admitted fragment identity; +- expose original, direct-fragment, and pure-reference Root forms; +- serve defensive copies through a verified provider; +- order fragment identities canonically; +- preserve all Language metadata, schema, list, and reference semantics; +- report `NotFound` for identities it did not admit rather than fabricating content. + +Expansion of the fragment graph reconstructs the same exact nodes. Collapsing the original graph to those fragment references preserves every Root BlueId. + +### E.7 Cyclic-member edges in fragments + +A finalized cyclic-set member identity `MASTER#index` is an opaque edge. An ordinary fragment may preserve that reference but MUST NOT claim that the member body is independently verifiable under that identity. + +An ordinary fragment provider therefore returns `NotFound` for the member unless it is composed with a cyclic-aware provider that verifies the complete owning set and member index. `this#index`, `ZERO_BLUEID`, malformed member suffixes, inline host object cycles, and cycles among ordinary local fragments remain invalid. + +A pure cyclic-set member is not an independently verifiable ordinary Root. A higher runtime may reject it as a processing Root while still permitting ordinary documents and events to contain opaque member references. + +*End of Blue Language Specification 1.0.* diff --git

Lifecycle. Registry construction eagerly verifies every + * resource and fails closed. A successfully constructed registry is immutable, + * thread-safe, and returns defensive node copies; the default instance can be + * shared for the process lifetime.

+ * + *

Extension. Built-in registry changes are protocol changes + * and require regenerated canonical resources, digests, package identity, and + * conformance evidence.

They may contain their own contracts, channels, lifecycle state, and internal events, but they are not independently committed sessions. A successful transition creates one new Root. Changed embedded nodes and every changed ancestor on their paths receive new BlueIds. Unchanged branches retain their existing BlueIds. + +An independently evolving or shared business object is modeled as another autonomous root connected by references and events. It is not modeled as one mutable embedded occurrence owned simultaneously by several roots. + +### 0.2 Processor boundary + +The normative operation is: + +```text +PROCESS(document, event) -> ProcessResult +``` + +where: + +- `document` is the exact current Root; +- `event` is the exact next external event selected by the managing feeder; +- `ProcessResult.document` is the exact resulting Root; +- `ProcessResult.events` contains only events emitted by the Root scope; +- `ProcessResult.totalGas` is the deterministic logical work admitted by the invocation; +- every tentative effect either commits in the one Root transition or is discarded. + +There is no authored target path, `deliveryOccurrence`, child session, Embedded Child Commit, or public effect log in the processing API. + +### 0.3 Feeder and processor + +The managing feeder connects external time to deterministic processing. + +```text +Feeder: + observes every active external channel declared by Root and embedded scopes; + maintains a revision-complete incremental subscription index; + obtains externally ordered entries and source-completeness evidence; + orders external events deterministically; + derives the exact channel-occurrence snapshot for the next event; + makes the selected graph branches and verified nodes available; + commits Root, Root outbox, subscription delta, and delivery progress atomically. + +Processor: + revalidates the derived occurrence snapshot; + opens only selected branches and semantically caused branches; + recognizes every required effective contract type; + loads only selected executable bodies and demanded data; + applies deterministic changes and internal reactions; + returns one new Root and Root's own events. +``` + +The feeder snapshot is derived execution metadata, not caller-authored Blue content and not a third semantic event field. For one managed-root revision, exact event, runtime registry, and activation state, the canonical snapshot is unique. + +### 0.4 Root-only public events + +An embedded scope may emit an event that is handled locally and observed by ancestors.

One invocation has one authoritative Root and at most one new authoritative Root. +3. Embedded scopes are owned state inside Root, not separately committed document sessions. +4. The feeder derives one complete, revision-bound external-delivery snapshot. +5. `PROCESS` never requires a recursive scan of the complete embedded surface. +6. Inline, referenced, expanded, collapsed, warm, cold, batched, and segmented representations produce the same semantic result and portable gas. +7. Every effective contract type in the initial participating closure is recognized before the first mutation; executable bodies remain lazy. +8. Patches use persistent copy-on-write and preserve unchanged children by exact BlueId. +9. Internal Document Updates and emitted events may reach ancestors without becoming public Root output. +10. `ProcessResult.events` contains exactly Root emissions, in order and with multiplicity. +11. Checkpoints bind to channel semantic identity and are written only after complete successful delivery. +12. Gas prices deterministic logical work, not cache state, provider bytes, or unchanged transitive content. +13. Runtime semantics are selected by exact runtime-type BlueId; no document-level version field is required. +14. Deterministic failure, gas exhaustion, or transient resource suspension before commit leaves the old Root authoritative and publishes no events. +15.

The feeder closes a safe external-order window. +2. It derives the complete preselected delivery snapshot for one Root revision. +3. The processor admits the exact Root and exact event. +4. It checks direct terminated state and preflights the complete participating closure. +5. Each raw External Channel occurrence is revalidated, accepted or rejected, + checkpoint-gated, and grouped into a logical delivery. +6. Required scopes initialize from Root toward the selected descendant. +7. Selected deliveries execute deeper scopes first; selected bodies remain lazy. +8. Patches rebuild the changed identity spine, Document Updates cascade + synchronously, and emitted events drain through the internal FIFO. +9. Successful source checkpoints are written after complete delivery. +10. The final Root is validated, its subscription delta is derived, and the + platform atomically commits Root, Root events, index delta, and progress. +``` + +At no point does the processor need to materialize the complete Root graph. A host may physically prefetch more, but only demanded and causally reached content affects semantics or gas. + +### 0.8 Key terms (informative) + +| Term | Meaning | +|---|---| +| **Root** | The one authoritative Blue document state supplied to `PROCESS`. | +| **Scope** | Root or one declared embedded object occurrence participating inside that Root. | +| **Raw external occurrence** | One snapshotted External Channel at one scope path. It owns acceptance and checkpoint state. | +| **Logical delivery** | One handler execution obtained after equivalent fresh raw sources are grouped. | +| **Delivery snapshot** | Revision-bound derived evidence describing every preselected raw occurrence for the event. | +| **EventOccurrence** | Internal FIFO run state for one emitted event, its source scope, and frozen ancestor chain. | +| **Root event** | An event emitted by Root and therefore included in `ProcessResult.events`. | + +The exact external event and the derived delivery snapshot are different things. The event is immutable Blue content. The snapshot is verified execution evidence and is never inserted into the event. + +### 0.9 Reusable embedded process modules (informative) + +A reusable embedded process type defines local state, local contract roles, operations, and any nested owned processes. One occurrence becomes self-contained when it is created: every local role is bound to an exact Channel node, either materialized inline or supplied as an equivalent pure BlueId reference. + +```text +Reusable Lesson type + declares teacherChannel and studentChannel roles + +Agreement occurrence + creates one Lesson + supplies exact teacher and student Channel nodes + declares the Lesson as embedded +``` + +The same Timeline, actor, or exact Channel definition may be reused in many embedded occurrences. Reuse does not duplicate the external history and does not merge the occurrences: each concrete scope path has its own lifecycle, checkpoint state, and document state. + +Contracts 1.0 does not define implicit parent-channel inheritance. An embedded scope does not search its parent or ancestors for a contract key, and changing a parent Channel does not silently change existing child occurrences. New occurrences may be assembled using the parent's current participant configuration; existing occurrences retain their exact bindings until an explicit workflow changes or replaces them. + +Dynamic collections of process occurrences are declared through `Process Embedded.collectionPaths` (§5.2). The collection uses stable object keys; every direct member becomes one concrete embedded scope. Raw wildcard syntax and implicit list-element embedding are not part of Contracts 1.0. + +--- + +## 1. Scope, Versioning, Registry, and Conformance + +### 1.1 Goal + +Blue Contracts and Processor 1.0 defines: + +- feeder-ordered external events; +- revision-complete subscription discovery; +- branch-local processing inside one Root; +- effective inherited application contracts and direct processor state; +- immutable dispatch snapshots and lazy bodies; +- deterministic channel and handler order; +- persistent mutation to Root; +- immediate Document Update cascades; +- internal event propagation and Root-only output; +- exact checkpoint and lifecycle behavior; +- one shared gas budget and canonical counter trace; +- whole-invocation atomicity and revision-bound platform commit. + +### 1.2 Out of scope + +This specification does not define: + +- Blue Language identity or resolution algorithms; +- authentication, signatures, authorization, or mandate eligibility; +- concrete source-provider transport or cryptographic proof formats; +- database schemas, cache layouts, or provider transport; +- user-interface behavior; +- consensus among independent platforms; +- hosted pricing, billing, or service-level policy; +- the implementation of one concrete compute runtime beyond its Contracts boundary. + +Concrete external channel and executable runtime types MAY define additional deterministic semantics through exact runtime-type BlueIds. They MUST preserve this specification's one-root, representation, atomicity, output, and gas-boundary rules. + +### 1.3 Version selection + +This document defines **Blue Contracts and Processor 1.0**, the first public-version Contracts specification. + +The first public release begins at 1.0 because internal working drafts did not establish an interoperability or compatibility surface. Implementations MUST treat this specification, its canonical runtime registry, gas manifest, and fixture package as one release unit. + +A document does not carry a required `contractsVersion` or `processorVersion`. The managed execution environment selects Contracts 1.0 before processing. Concrete runtime semantics are selected by exact runtime-type BlueId and the separately published specification bound to that type. + +After a runtime-type BlueId is published, that exact BlueId MUST never acquire different semantics, dispatch fields, subscription extraction, or gas weights. + +A later incompatible change to `PROCESS`, delivery ordering, embedded-scope behavior, event propagation, checkpoints, lifecycle, atomicity, or the core gas schedule requires a new Contracts version. + +### 1.4 Runtime registry + +The canonical runtime registry is part of the Contracts 1.0 release. For every core or portable runtime type it MUST publish: + +- exact canonical Blue node and BlueId; +- runtime role; +- dispatch fields and executable-body fields; +- exact subscription functions for an External Channel; +- checkpoint-domain semantics; +- exact execution semantics or binding to another published specification; +- named runtime counters and weights when executable; +- deterministic limits and error categories; +- conformance fixtures that exercise the type. + +Registry source, calculated BlueIds, prose, fixtures, and gas manifest MUST agree. Implementations MUST NOT guess when they conflict. + +The implementation-baseline runtime registry package identity is: + +```text +sha256:46a7744c1cbfa4b00e1d8a99f6ca3f0089ef697de968fee08547894ab02b0ca1 +``` + +The machine-readable `blue-contracts/gas/1.0` manifest is normative for counter names, weights, formulas, and portable limits. Its implementation-baseline package identity is: + +```text +sha256:88c7bbe77d531c9e973cae13002c3464a2c14568833adf5d804d13b7b3d26af5 +``` + +### 1.5 Conformance + +A conforming implementation MUST: + +- implement every normative rule in this document; +- use Blue Language 1.0; +- recognize the canonical core runtime BlueIds; +- implement `PROCESS(document, event)` and the platform commit obligations; +- support all processor-managed contracts and events in Appendix A; +- support exact feeder snapshot revalidation; +- produce the canonical named gas trace required by §13 in conformance mode; +- pass every machine-readable Contracts 1.0 fixture; +- report the exact registry, gas-manifest, and fixture-package identities it implements. + +A component implementing only the processor library, feeder, node store, or a runtime may describe that component precisely, but MUST NOT claim complete Contracts 1.0 platform conformance unless the combined system satisfies all obligations. + +This specification intentionally defines a generic runtime boundary rather than one normative business channel or workflow language. The conformance harness uses identity-bound scripted runtime types to exercise that boundary. Real end-to-end applications require one or more separately published concrete External Channel and Handler/runtime specifications, each selected by exact runtime-type BlueId. + +--- + +## 2. Processing Inputs, Environment, Result, and Atomicity + +### 2.1 Processing Document + +`document` is an admitted exact Blue node. It MAY be inline, a pure reference, or partially materialized, but its exact Root BlueId MUST be established before semantic execution. The logical Root MUST be an object node. + +The Processing Document need not be a complete Resolved Form or a closed graph. Contract fields, type contributions, schemas, values, and executable bodies are expanded and resolved on demand. + +A higher-level API MAY accept Source syntax and preprocess it before `PROCESS`. That preprocessing is outside the invocation and MUST yield the same admitted Root identity on every conforming platform. + +### 2.2 Processing Event + +`event` is an admitted exact immutable Blue node. Its exact BlueId MUST be established before semantic execution. A higher-level API MAY preprocess Source-event syntax before `PROCESS`. + +The event is never rewritten to contain a target path or delivery occurrence. Exact identity, signatures, source-chain links, and checkpoint subjects therefore remain stable. + +### 2.3 Processing environment + +A managed invocation is evaluated under a fixed environment containing: + +```text +Blue Language 1.0 selection +Contracts 1.0 core gas schedule +exact runtime registry and supported runtime BlueIds +verified exact-node provider domain +managed-root session identity and current revision +revision-complete external-channel snapshot and activation intervals +canonical external-delivery plan for this Root revision and event +exact external-order policy identity +exact initial-subscription-frontier policy identity +exact poison-event/quarantine policy identity +exact Language release, Contracts release, runtime-registry, and gas-manifest identities +shared gas limit +``` + +This environment is not Blue content. It MUST be fixed for the attempt and auditably bound to the managed-root revision. + +An implementation MAY pass the canonical delivery plan to an internal processor API. The plan is a derived accelerator. It is conforming only when it equals the unique plan defined by §3. It does not change the two-input semantic operation. + +### 2.3.1 Cyclic-member processing boundary + +A final cyclic-set member identity `MASTER#index` may appear as an opaque edge inside an ordinary Root or event. It is not independently hash-verifiable and therefore MUST NOT be admitted as the top-level mutable Root or top-level event of `PROCESS`. Those inputs fail before provider demand. + +A `Process Embedded` path MUST NOT terminate at or traverse through an opaque cyclic-member edge. Structural access to an ordinary opaque member requires a cyclic-aware provider with complete set proof. Carrying an untouched opaque edge and replacing the whole edge with another admitted exact value remain valid. + +### 2.4 ProcessResult + +A completed invocation returns: + +```text +ProcessResult { + status + document + events + totalGas + diagnostic? +} +``` + +`document` is the exact resulting Root on success. Every noncommitting status returns the exact input Root. + +`events` is an out-of-band ordered sequence of exact Blue event nodes emitted by Root during the invocation. It preserves order and multiplicity. The sequence is not itself a Blue List node and has no independent BlueId inside `PROCESS`; a platform MAY wrap it in a Blue outbox envelope after processing. It is empty for every noncommitting status. + +`totalGas` is the sum of admitted canonical counters. A conformance/debug API MUST be able to expose the exact named trace; an ordinary API MAY omit it. + +`diagnostic` is deterministic, non-authoritative explanatory data. It is not part of Root or event identity. + +### 2.5 Atomic invocation + +All runtime state is tentative until the invocation completes: + +- patches and rebuilt nodes; +- processor markers and checkpoints; +- internal queues; +- runtime outputs; +- Root events; +- subscription-delta validation; +- gas trace. + +A committing `success` returns the tentative Root and Root events. Every deterministic failure or gas exhaustion discards all tentative state and events and returns the input Root. + +Transient acquisition failure does not produce a completed `ProcessResult`; the host suspends the attempt and retries from the exact input Root and event with more verified evidence. + +### 2.6 Representation invariance + +For graph-equivalent Root and event inputs under the same environment, a conforming implementation MUST return: + +- the same status and diagnostic category; +- the same resulting Root BlueId; +- the same ordered Root event identities; +- the same exact counter trace and total gas; +- the same semantic provider demands. + +Physical fetch count, cache hits, allocation, node batching, and serialized bytes are not portable outputs. + +### 2.7 Platform commit + +A committing result is installed only through compare-and-swap against the exact Root BlueId and revision from which it was calculated. + +The platform transaction MUST atomically persist: + +```text +new Root and new revision +Root outbox = ProcessResult.events +validated incremental subscription-index delta +subscription activation and retirement intervals +delivery progress for the external event +``` + +For a nonmutating terminal result, the platform MUST compare-and-swap delivery progress against the exact unchanged Root BlueId and revision. This prevents a `no-match`, `stale`, or failure decision calculated on an old Root from suppressing an event that a newer Root would handle. + +A compare-and-swap conflict commits nothing. It is host contention, not portable Contracts gas; the event is re-derived from the new authoritative revision. + +--- + +## 3. Managing Feeder, Subscriptions, and External Order + +### 3.1 Feeder responsibility + +The managing feeder MUST: + +- derive the active external subscription surface from Root and transitively declared embedded scopes; +- maintain that surface incrementally for each committed Root revision; +- observe every active source identified by that surface; +- obtain the completeness evidence required by each concrete external-source specification; +- select the chronologically next eligible external event; +- derive and retain the canonical delivery snapshot; +- ensure one event reaches a terminal progress record before a later external event begins; +- keep the subscription index at the authoritative Root revision. + +The initial admission of a managed Root MAY inspect its complete declared subscription surface once. Later revisions MUST be updated from changed branches and effective dependencies; a complete recursive scan before every event is nonconforming to the locality objective. + +### 3.2 External-channel snapshot + +For every active External Channel occurrence, the feeder stores a deterministic snapshot: + +```text +ExternalChannelSnapshot { + scopePath + channelKey + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + order + dispatchHeader + subscriptionKeys + checkpointDomainBlueId + declaredSameScopeChannelDependencies + sameScopeChannelCatalogIdentity? +} +``` + +The snapshot is derived from the effective channel contract at one Root revision. It does not require an invented BlueId for a merged effective contract. `orderedSourceContributionNodeBlueIds` records exact ancestor-to-descendant contributions. + +The dispatch header contains only the bounded immutable fields registered by that channel type. Executable body fields are not part of the subscription snapshot. + +### 3.3 Required external-channel functions + +Each portable External Channel runtime type MUST define exact deterministic functions: + +```text +CHANNEL_KEYS(snapshot) -> finite ordered set of subscription keys +EVENT_KEYS(event) -> finite ordered set of event keys +PRESELECTS(snapshot, event) -> Boolean +ACCEPTS(snapshot, event, context) -> Boolean +PAYLOAD(snapshot, event, context) -> exact channelized Blue node, when accepted +CHECKPOINT_DOMAIN(snapshot, context) -> exact BlueId +CHECKPOINT_SUBJECT(snapshot, event, payload, context) -> exact node identity +DECLARE_CHANNEL_DEPENDENCIES(snapshot, context) -> exact keys or bounded whole-catalog declaration +HANDLER_CHANNEL_KEY(snapshot, event, payload, context) -> same-scope Channel key +LOGICAL_DELIVERY_KEY(snapshot, event, payload, context) -> deterministic Text +``` + +The following laws are normative: + +1. `ACCEPTS(snapshot, event) => PRESELECTS(snapshot, event)`. +2. `PRESELECTS(snapshot, event) => intersection(CHANNEL_KEYS(snapshot), EVENT_KEYS(event)) is non-empty`. +3. `PRESELECTS`, `ACCEPTS`, and `PAYLOAD` depend only on the immutable snapshot, exact event, registered deterministic semantics, and explicitly demanded event content. +4. They MUST NOT depend on mutable Root fields, initialization effects, cache state, wall-clock time, or ambient I/O. +5. Business-state conditions belong in Handler predicates or workflow logic, not External Channel acceptance. +6. The functions are representation-blind and bounded by the portable limits. + +A channel that cannot provide finite subscription keys is not a portable External Channel under Contracts 1.0. + +#### 3.3.1 Same-scope Channel dependencies + +An External Channel may need immutable headers from another same-scope Channel in order to classify an accepted event. This is a generic Contracts capability; it does not imply that the peer Channel is an external source for the event. + +During subscription/header evaluation the runtime MUST declare either: + +```text +one or more exact same-scope Channel keys +or +one bounded complete same-scope Channel catalog +``` + +The retained subscription interval records the declared dependency surface and its exact identity. The complete catalog contains the canonical raw-key membership of the effective `contracts` map and read-only header snapshots for every effective same-scope Contract whose runtime role is External Channel or Processor Channel. It does not include executable bodies. + +During event classification the runtime receives a read-only context with exact lookup: + +```text +LOOKUP_CHANNEL(rawKey) -> CHANNEL(snapshot) | ABSENT | NON_CHANNEL +``` + +`ABSENT` is valid only when a declared complete catalog establishes that the raw key is semantically absent. `NON_CHANNEL` establishes that an effective Contract exists at the raw key but its runtime role is not a Channel. A lookup outside the declared dependency surface, unavailable evidence, changed contribution identity, or incomplete catalog MUST fail closed; it MUST NOT be converted to `ABSENT`. + +A `ChannelMemberSnapshot` contains only: + +```text +raw key +order +effective type BlueId +runtime role +ordered source-contribution BlueIds +registered immutable dispatch/header fields +deterministic dependency BlueIds +header identity +``` + +Reading a peer snapshot MUST NOT evaluate that peer as an External Channel, give it checkpoint authority, run its handlers, or load an executable body. + +#### 3.3.2 Source Channel and handler Channel + +Every accepted raw External Channel occurrence has two channel identities: + +```text +sourceChannelKey +handlerChannelKey +``` + +The source Channel performed external acceptance and owns checkpoint domain, checkpoint subject, and checkpoint write. `HANDLER_CHANNEL_KEY` defaults to the source key but MAY select another declared same-scope Channel key. The selected target MUST resolve to a `CHANNEL` lookup result. A concrete runtime MAY define ordinary-source fallback for `ABSENT` or `NON_CHANNEL`; the fallback rule is part of that exact runtime type and MUST be deterministic. + +The target Channel is not evaluated as another external occurrence and is not checkpointed merely because it is the handler target. Handlers are selected by the frozen `handlerChannelKey`. + +Informative example: + +```text +sourceChannel accepts an externally attributed message +message payload names operationsChannel as the effective target +handlers bound to operationsChannel execute +sourceChannel owns the checkpoint +operationsChannel is not separately accepted or checkpointed +``` + +This supports delegated or routed operation protocols without rewriting the external event or adding a third `PROCESS` input. + +#### 3.3.3 Logical delivery grouping + +After rejection and stale filtering, accepted-new raw source occurrences are grouped by: + +```text +(scopePath, logicalDeliveryKey) +``` + +The default `logicalDeliveryKey` is the raw source key. Every source in one group MUST agree on: + +```text +exact payload identity +handlerChannelKey +logical delivery identity +``` + +One group executes the target handlers exactly once. Every fresh participating source retains its own checkpoint domain and subject. All participating source checkpoints commit only after the grouped handler execution and caused internal-event drain succeed. Failure, termination before checkpoint, cut-off, gas exhaustion, or rollback commits none of the group's source checkpoints. Rejected and stale sources are not participants. + +If fresh sources assigned to one group disagree on payload identity, handler Channel identity, or logical delivery identity, classification fails atomically with `runtime-fatal` and diagnostic category `InconsistentLogicalDelivery`. No initialization, Handler execution, checkpoint, Root event, or document mutation commits. + +Logical grouping is run state, not Blue content and not part of `ProcessResult`. + +### 3.4 Revision-complete subscription index + +Before the feeder selects an event: + +```text +subscriptionIndex.indexedRootRevision == managedRoot.revision +subscriptionIndex.indexedRootBlueId == managedRoot.currentRootBlueId +``` + +MUST hold. + +The index MAY physically over-approximate and return false positives. Before canonical delivery ordering and portable occurrence limits are applied, raw candidates MUST be filtered by exact `PRESELECTS` using the current channel snapshot and event. + +The index MUST NOT omit an active snapshot for which `PRESELECTS` is true. Omission is infrastructure nonconformance, not `no-match`. + +A direct terminated marker prunes that scope and all declared descendants from later subscription snapshots. + +### 3.5 Subscription activation intervals + +Feeder state MUST record when one channel occurrence begins and ends observing external order: + +```text +SubscriptionInterval { + scopePath + channelKey + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + activationRootRevision + startAfterExternalOrderKey + endAtRootRevision? +} +``` + +For initial Root admission, platform policy MUST explicitly choose one frontier per external source: + +```text +full history +from a declared order key +from the admission order key +``` + +A channel or embedded scope introduced while processing event `E` begins strictly after `E`'s canonical external-order key. It never joins `E`. + +Removing and later re-adding a channel starts a new interval unless the exact channel runtime type explicitly defines a deterministic checkpoint/cursor migration. Reusing the same contract key does not silently resume a semantically different channel. + +### 3.6 External completeness and canonical order + +The feeder MUST not process event `E` until the concrete external-source ecosystem has supplied completeness evidence that no active subscribed source can later produce an eligible event ordered before `E`. + +Each concrete external-source specification MUST publish: + +```text +source-local order key +source-local completeness rule +stable source identity used by the external-order policy +``` + +The managed execution environment binds one exact **external-order policy identity**. That policy MUST define a strict total order over eligible events from all active sources and satisfy all of these laws: + +1. **Per-source consistency.** If one source's final order places `A` before `B`, the cross-source policy MUST also place `A` before `B`. +2. **Totality.** For any two distinct eligible event occurrences, exactly one orders before the other. +3. **Determinism.** The result depends only on identity-bound source evidence and policy fields, never arrival order, query order, cache state, locale, or host scheduling. +4. **Stable tie-breaking.** Equal source-neutral time values or other primary keys are resolved by exact identity-bound tie-break fields published by the policy. +5. **Policy stability.** The policy identity is fixed for the managed-root session or changed only through an explicit migration that defines progress continuity. +6. **Completeness compatibility.** Before selecting `E`, the feeder has evidence from every active source interval that no still-eligible event can later appear with a global order key less than `E`. + +Contracts core treats concrete order-key components as opaque evidence. It does not define clocks, timelines, providers, or one universal tie-break tuple. + +An informative feeder loop is: + +```text +repeat: + assert subscription index matches authoritative Root revision + obtain each active source's next known event and completeness frontier + choose the least globally ordered candidate E + wait until every active source proves no eligible event precedes E + derive the complete preselected delivery snapshot for E + process and persist one revision-bound terminal result for E +``` + +No later external event may interleave with the retained deliveries of the current event. The complete canonical delivery set of `E` reaches one terminal progress record before the feeder begins `E2`. + +### 3.7 Canonical delivery snapshot + +For Root revision `R` and event `E`, the feeder selects every active interval whose snapshot satisfies `PRESELECTS(snapshot, E)`. + +It records: + +```text +ExternalDelivery { + scopePath + channelKey + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + order + checkpointDomainBlueId +} +``` + +Canonical order is: + +1. greater `scopePath` depth first; +2. normalized `scopePath` by Unicode code-point order; +3. effective channel `order`, ascending; +4. raw `channelKey`, Unicode code-point order; +5. effective type BlueId as a final deterministic tie-breaker. + +The snapshot is retained across retries against the same Root revision. A new Root revision requires a new snapshot. + +### 3.8 Revalidation and false positives + +The processor revalidates every delivery before use: + +- each path segment remains declared by the snapshotted Process Embedded contribution; +- the scope exists as an object and is not under a direct terminated scope; +- the same effective channel contribution identity remains at the same key; +- the channel type and checkpoint domain match the snapshot; +- `PRESELECTS` and `ACCEPTS` are re-evaluated against the exact event. + +A stale physical index false positive therefore becomes a deterministic skipped or rejected occurrence. An omitted true occurrence is not harmless and is feeder failure. + +### 3.9 Terminal delivery progress and poison events + +Every terminal outcome is persisted against the exact Root revision: + +```text +success +no-match +stale +terminated +capability-failure +invalid-processing-document +runtime-fatal +gas-limit-exceeded +portable-limit-exceeded +subscription-surface-invalid +``` + +A completed event is not automatically resubmitted against the same revision. Repeated deterministic failure or gas exhaustion MUST be quarantined or explicitly administratively retried; it MUST NOT block the external-order queue forever through unbounded automatic retry. + +--- + +## 4. Contracts, Runtime Types, and Discovery + +### 4.1 `contracts` map + +Every scope MAY contain an effective `contracts` object: + +```yaml +contracts: + : +``` + +Contract entries are ordinary identity-bearing Blue content. Application contracts are obtained from the effective Language-resolved contracts map. Processor state at reserved keys is always direct state and is never inherited. + +### 4.2 Contract-map key grammar + +A contract key MUST: + +- be non-empty Text; +- be a legal ordinary Blue child key; +- not equal a Language reserved or reserved-invalid key; +- contain at most 256 Unicode code points and 1,024 UTF-8 bytes; +- be representable as one escaped Runtime Pointer segment. + +`/` and `~` are allowed in the raw key and are escaped only for pointers. + +### 4.3 Runtime roles + +Every effective Contract subtype has one registered runtime role: + +| Role | Meaning | +|---|---| +| External Channel | Entry point for the external `PROCESS` event. | +| Processor Channel | Entry point for Document Update, Triggered, Lifecycle, or Embedded delivery. | +| Handler | Deterministic logic bound to one same-scope channel key. | +| Marker | Runtime state or policy; does not execute as a handler. | +| Executable extension | A registered additional role with exact semantics. | + +A Contract subtype with an unsupported role or exact type is not inert. It is subject to must-understand failure. + +### 4.4 Effective contract snapshot + +For every effective contract key demanded by processing, the processor constructs an immutable out-of-band snapshot: + +```text +EffectiveContractSnapshot { + scopePath + key + orderedSourceContributionNodeBlueIds + effectiveTypeBlueId + role + order + resolvedDispatchFields + executableBodyNodeBlueIds + deterministicDependencyNodeBlueIds +} +``` + +The snapshot records exact contributions rather than manufacturing a synthetic merged-contract BlueId. + +The runtime implementation for `effectiveTypeBlueId` defines which fields it demands at each stage. The generic processor MUST resolve the type of every effective contract in a participating scope, but MUST NOT load an executable body merely to classify or reject the entry. + +### 4.5 Direct processor state first + +Before enumerating application contracts in a scope, the processor reads and validates direct reserved state: + +```text +contracts/terminated +contracts/initialized +contracts/checkpoint +``` + +A valid direct terminated marker makes the scope inactive. Unsupported application contracts inside that inactive scope are not recognized for the current invocation. + +A type-derived initialized, terminated, or checkpoint marker has no runtime effect. + +### 4.6 Must-understand preflight + +Before the first mutation, the processor MUST preflight the complete **initial participating closure**: + +- every preselected delivery scope that still exists; +- every declared ancestor from Root to those scopes; +- every effective contract type in those scopes; +- direct processor marker shapes; +- Process Embedded path structure; +- handler/channel binding structure; +- portable limits required before execution. + +Preflight recognizes types and dispatch fields but not unselected executable bodies. + +If an unsupported type, role, or required dispatch rule is found, the invocation returns `capability-failure`, input Root, no events, and admitted gas. + +A patch or generated write affecting `/contracts`, `/type`, a type contribution, or another effective-contract dependency MUST repeat must-understand validation for the changed effective closure before processing continues or commit occurs. + +### 4.7 Deterministic ordering + +Channels and handlers are ordered by: + +1. effective `order`, ascending; absent means `0`; +2. raw contract key, Unicode code-point order. + +The canonical candidate list begins in contract-key order and is sorted by the stable merge-sort accounting rule in §13.10. Implementations MAY use indexes, but the logical order and trace are fixed. + +### 4.8 Dispatch snapshots + +For one channel delivery, the handler candidate list is snapshotted immediately before the first handler predicate is tested. The snapshot freezes key, contribution identities, effective type, dispatch fields, order, and body identities. + +Changes to contracts during that delivery do not add, remove, reorder, or replace candidates in the current snapshot. They affect later discovery points. + +For an accepted external delivery, its channel snapshot, payload, checkpoint domain, and checkpoint subject are frozen before initialization. Initialization may change the current contracts map, but the already accepted delivery continues from its frozen snapshot unless its scope is cut off or terminated. Handler discovery occurs after initialization and therefore observes post-initialization contracts. + +### 4.9 Same-scope binding + +A Handler binds to exactly one channel key in the same scope through its effective `channel` field. A missing same-scope channel makes the Handler inert unless its exact runtime type declares that shape invalid. + +The effective contracts of an embedded scope are resolved from that scope's own content, type chain, and overlays. Embedding does not import, inherit, or alias contracts from a parent or ancestor scope. A contract key in an ancestor has no same-scope effect in the child merely because the raw key is equal. + +An exact Channel node may be reused in several scopes. These are representation-equivalent bindings: + +```yaml +teacherChannel: + blueId: +``` + +```yaml +teacherChannel: + type: + # exact materialized content whose BlueId is ExactChannelBlueId +``` + +The two forms identify the same Channel value. They do not create a live link to another contract-map key. If a parent later replaces its own Channel, an existing child reference still identifies the old exact Channel until the child occurrence is explicitly changed. + +Contracts 1.0 defines no informal `Parent Channel`, ancestor-key lookup, nearest-parent lookup, or context-dependent channel port. A future runtime may define an explicit cross-scope binding type only through a separately published exact runtime-type BlueId and complete dependency, subscription, checkpoint, invalidation, cycle, and gas semantics. Implementations MUST NOT infer such behavior from ordinary embedding or raw key equality. + +A child event reaches an ancestor only through an Embedded Node Channel. A descendant field change reaches an ancestor through a Document Update Channel. + +### 4.10 Effective protected state + +The following state is processor-protected: + +```text +direct initialized marker identity +direct terminated marker identity +direct checkpoint marker identity +effective Process Embedded type and every non-path field +effective Type Generalization Policy +``` + +For every application patch and generated type write: + +```text +EFFECTIVE_PROTECTED_STATE(before) + == +EFFECTIVE_PROTECTED_STATE(after) +``` + +MUST hold, except that an explicitly permitted patch to the declaration fields `contracts/embedded/paths` or `contracts/embedded/collectionPaths` may change only those declaration fields while preserving the exact Process Embedded type and every other effective field. + +This comparison catches indirect changes caused by replacing `/type`, `/contracts`, or an ancestor of a protected contribution. + +### 4.11 Execution context + +A runtime call may receive only deterministic values: + +```text +$scope current scope path +$document read-only view of current Root +$event current channelized payload +$processingEvent original external PROCESS event +$contract frozen current contract snapshot +$channel frozen channel snapshot, when applicable +$gas shared live-bounded meter +``` + +The context MUST NOT expose wall-clock time, randomness, ambient I/O, host object identity, mutable caches, thread scheduling, or unregistered state. + +### 4.12 ContractExecutionResult + +A Handler or executable Channel returns: + +```text +ContractExecutionResult { + patches ordered list, default [] + events ordered list, default [] + termination optional + runtimeLedger optional only when not debiting the shared meter directly +} +``` + +Application order is: + +1. validate and merge the runtime ledger exactly once; +2. apply patches in list order, each with its complete synchronous Document Update cascade; +3. record emitted events in list order; +4. apply the first termination request. + +An invalid result shape fails before any effect from that result is applied. Whole-invocation atomicity still discards earlier tentative effects. + +### 4.13 Runtime body demand and meter + +A candidate body is demanded only after its matcher succeeds. Passing an already admitted exact node into or out of a runtime preserves its BlueId and MUST NOT recursively clone, serialize, or size it. + +A runtime either debits the shared meter live or uses a child meter initialized with the exact remaining budget. It MUST NOT do both for the same work. A child ledger is validated and merged exactly once. + +--- + +## 5. Root and Embedded Scopes + +### 5.1 Scope + +A **scope** is an object node inside Root that owns an effective contracts map and is either: + +- Root at `/`; or +- a path declared by the nearest ancestor's effective Process Embedded contract. + +The root scope always exists. A declared embedded scope exists only while its path contains an object node. + +### 5.2 Process Embedded + +The reserved key `contracts/embedded` contains a Process Embedded marker. It has two explicit declaration forms: + +```yaml +contracts: + embedded: + type: Process Embedded + + paths: + - /payment + - /delivery + + collectionPaths: + - /lessons + - /refunds +``` + +`paths` contains exact Runtime Pointers. Each path identifies one immediate owned embedded scope root. + +`collectionPaths` contains exact Runtime Pointers to object-compatible collection nodes. Every direct ordinary member present under such a collection becomes one immediate owned embedded scope root at the concrete path: + +```text +collection path: /lessons +member key: lesson-17 +concrete scope: /lessons/lesson-17 +``` + +The collection container itself is not an embedded scope unless it is separately declared by a different valid ancestor marker. One Process Embedded marker MUST contain at least one non-empty `paths` or `collectionPaths` list after effective resolution. + +Process Embedded defines: + +1. owned child contract scopes; +2. mutation boundaries; +3. the recursive feeder subscription surface. + +It does not broadcast the current external event to every child. It does not import parent contracts into a child. It never turns a contract entry under `/contracts` into a scope. + +### 5.3 Embedded declaration validity + +Every entry in `paths` and `collectionPaths` MUST: + +- be a normalized Runtime Pointer beginning with `/`; +- not equal `/`; +- use object-member segments only; +- not traverse list positions; +- not contain wildcard, glob, selector, or query syntax; +- not pass through `contracts`, `type`, `schema`, `items`, or another Language-reserved field; +- be unique within its declaration list; +- not overlap another immediate declaration by ancestor/descendant relation. + +A `paths` entry may be absent from the current document and then contributes no active scope. When present, it MUST resolve to an object node or a verified pure reference to an object node. + +A `collectionPaths` entry may be absent and then contributes no active scopes. When present, it MUST resolve to an object-compatible node. Lists are not collection targets under Contracts 1.0. Every direct ordinary member under the collection MUST be an object node or a verified pure reference to an object node. A present scalar, list, cyclic-member boundary, or otherwise non-object member makes the subscription surface invalid. + +For one collection, direct member keys are ordered by Unicode code-point order. Each key is escaped as one Runtime Pointer segment to derive its concrete scope path. The processor and feeder MUST use the concrete paths, not a wildcard expression, in delivery snapshots, activation intervals, checkpoints, propagation chains, and diagnostics. + +The combined concrete child set from `paths` and `collectionPaths` MUST be duplicate-free. It is invalid when: + +- an explicit `paths` entry equals a collection-generated member path; +- one declaration is a strict ancestor or descendant of another immediate declaration; +- the same collection is declared twice through graph-equivalent pointers; +- two declarations generate the same concrete path. + +Traversal MUST reject an embedded ancestry cycle, including revisiting the same exact node on the current declared ancestor chain. + +### 5.4 Entry snapshot and collection membership + +When a scope first participates, the processor freezes: + +```text +ENTRY_EXPLICIT_EMBEDDED_PATHS(scope) +ENTRY_EMBEDDED_COLLECTION_PATHS(scope) +ENTRY_COLLECTION_MEMBER_KEYS(scope, collectionPath) +ENTRY_EMBEDDED_PATHS(scope) # exact combined concrete child paths +ENTRY_SCOPE_ROOT_IDENTITY(scope) +ENTRY_ANCESTOR_CHAIN(scope) +``` + +For each collection path, `ENTRY_COLLECTION_MEMBER_KEYS` is the complete direct key set in Unicode code-point order. `ENTRY_EMBEDDED_PATHS` is produced by combining exact `paths` entries with every concrete collection-member path and then applying canonical Runtime Pointer ordering. + +The frozen concrete path set is used for current-event path verification, mutation boundaries, delivery ordering, cut-off, and propagation. Changes to `paths`, `collectionPaths`, collection membership, or direct collection keys affect later external events only. + +A member added while processing event `E` is ordinary tentative Root content during `E`; it is not a participating scope for `E`. After commit it begins a new subscription interval strictly after `E`'s external-order key. A removed member retires its occurrence at the committed revision. Removing and later re-adding the same key creates a fresh occurrence interval and does not reuse the prior occurrence's checkpoint state unless an exact runtime type defines an explicit deterministic migration. + +The entry root identity identifies the active occurrence for cut-off detection. Ordinary persistent writes strictly inside the occurrence create new node identities but preserve the occurrence. A whole-occurrence replacement by an ancestor with a different exact node ends it. + +### 5.5 Participating closure + +A scope participates when it: + +- has an accepted new external delivery; +- is an ancestor required to initialize or observe such a delivery; +- receives a Document Update; +- receives an internal emitted event; +- receives a lifecycle event. + +The initial closure is known from the external delivery snapshot and its ancestors. Additional internal participation is recognized at the first caused delivery. + +Sibling and unrelated embedded branches remain inactive and MUST NOT be semantically expanded or discovered. + +### 5.6 One authoritative Root + +An embedded scope has no separate committed current-state record. Its current state is the exact node reachable from the authoritative Root. + +An implementation MAY store tentative intermediate nodes by BlueId. Storage does not make them current state. Only the final Root compare-and-swap does. + +### 5.7 Mutation boundaries + +Let `S` be the executing scope and `E(S)` its immediate child roots from the exact combined `ENTRY_EMBEDDED_PATHS(S)`, including collection-generated concrete member paths. + +An application patch from `S` MAY: + +- change a strict descendant of `S` that is not strictly inside any child root in `E(S)`; +- add, replace, or remove one immediate child root in `E(S)` as a whole; +- add a new direct member under an entry-snapshotted `collectionPaths` container, provided the final value is an object-compatible node and the resulting subscription surface is valid. + +A newly added collection member is not added to `E(S)` for the current event. It becomes an embedded occurrence only after the new Root commits and the next revision's subscription surface is derived. + +It MUST NOT: + +- patch document Root `/`; +- replace or remove its own scope root; +- patch strictly inside an immediate child root; +- patch a strict ancestor of an immediate child root; +- replace or remove a collection container as a whole while it contains entry-snapshotted active child roots; +- cross into a cyclic-set member. + +The strict-ancestor rule is intentionally simple. Authors must use an exact child-root operation rather than an ambiguous ancestor replacement. + +### 5.8 Active-scope cut-off + +When an ancestor removes an active embedded scope root or replaces it with a different exact node: + +- that active occurrence and all active descendants are marked cut off; +- pending external deliveries at those paths are skipped; +- no new local handler begins there; +- unapplied patches, events, and termination requests from its current buffered result are discarded; +- no initialization, checkpoint, or termination marker is written into the replacement; +- a currently executing call may return, but the processor checks cut-off before applying each remaining buffered effect; +- events already emitted before cut-off continue along the ancestor chain frozen at emission; +- the Document Update that caused cut-off continues along its frozen receiving chain; +- re-adding the same path does not resurrect the old occurrence during this invocation. + +Replacing a child root with the exact same current BlueId is a semantic no-op and does not cut off the occurrence. + +The processor MUST check cut-off after every nested cascade and before every marker or checkpoint write. + +### 5.9 Frozen propagation chains + +Every emitted event and every Document Update freezes its source scope and active ancestor chain when the occurrence is created. Later changes to Process Embedded declarations do not redirect an already-created occurrence. A removed or terminated receiving ancestor may stop its own local reaction, but an event that already happened is not silently rewritten to have a different source. + +### 5.10 Participant bindings in reusable process occurrences (normative boundary; informative pattern) + +A reusable process type may declare local Channel roles such as `teacherChannel`, `studentChannel`, `buyerChannel`, or `sellerChannel`. Each concrete occurrence supplies exact Channel values for those local keys. The values may be inline or equivalent pure BlueId references. + +The process occurrence is self-contained after creation. Its current subscription surface and authority are functions of its own exact content and registered runtime semantics, not of the unrelated current content of its parent. + +Recommended application behavior is: + +```text +new process occurrence: + instantiate using the enclosing document's current participant configuration + +existing process occurrence: + retain its exact bindings + +participant change inside one occurrence: + perform an explicit authorized workflow that replaces local Channel values + +agreement-wide migration: + explicitly update or replace the selected existing occurrences +``` + +For a Channel-changing event, the pre-change frozen source snapshot authorizes and checkpoints the current delivery. The new Channel surface becomes active only after the Root transition commits. Thus an old participant set may validly govern the transition to a new participant set, while later events use the new set. + +Changing a parent Channel does not silently rewrite a child's exact binding. Contracts 1.0 intentionally chooses explicit participant snapshots over context-dependent live parent lookup. + +### 5.11 Addressing dynamic collection members (normative boundary; informative example) + +`collectionPaths` declares which object members are active embedded scopes. It does not define how an external protocol addresses one member. Addressing is part of the concrete External Channel runtime through `CHANNEL_KEYS`, `EVENT_KEYS`, `PRESELECTS`, and `ACCEPTS` (§3.3). + +A concrete channel may use a stable document-routing identity in the event and scope header. For example, a Timeline Entry protocol may derive keys from: + +```text +documentId + timeline identity + actor identity +``` + +This allows many embedded process occurrences to reuse one physical Timeline while the feeder selects only the occurrence named by the event's `documentId`. Another channel type may use a different finite target projection. + +A stable logical document identifier and a BlueId serve different purposes: + +```text +stable document-routing identity: + identifies the continuing process occurrence for the external protocol + +BlueId: + identifies one exact immutable state of that occurrence +``` + +Contracts core does not mandate a field named `documentId`; it requires each portable External Channel type to publish finite, deterministic subscription and event keys. If a channel's keys do not distinguish several occurrences sharing one source, all matching occurrences may be preselected and normal canonical delivery rules apply. + +--- + +## 6. Events and Processor-Managed Channels + +### 6.1 Event model + +Events are immutable Blue nodes. The processor distinguishes: + +- the one external `PROCESS` event; +- lifecycle events; +- Document Update payloads; +- application events emitted by handlers; +- Embedded Event Delivery wrappers used for ancestor observation. + +Only application or lifecycle events emitted by Root are included in `ProcessResult.events`. + +### 6.2 External Channel + +An External Channel is evaluated only for an occurrence in the canonical feeder snapshot. + +For one occurrence, the processor: + +1. revalidates its path and channel snapshot; +2. evaluates `PRESELECTS` and `ACCEPTS` against the exact event; +3. constructs and freezes the channelized payload; +4. calculates and freezes checkpoint domain and subject; +5. evaluates checkpoint newness; +6. if new, initializes the required scope chain and invokes matching handlers. + +External Channel acceptance is immutable for this event and cannot read mutable Root business state. A Channel may accept while no Handler matches; the accepted new occurrence is still checkpointed. + +### 6.3 Document Update + +Every successful application patch or generated type-generalization write creates one immutable **update occurrence** in run state. The occurrence freezes: + +```text +absolute changed path from Root +absolute patch-origin scope path +before/after exact snapshots and presence +frozen receiving ancestor chain +semantic update operation +``` + +The underlying occurrence is created once. For each receiving scope, the processor deterministically renders one scope-relative Document Update payload: + +```yaml +type: Document Update +op: add | replace | remove +path: +beforePresent: true | false +before: +afterPresent: true | false +after: +sourceScopePath: +``` + +The payload may therefore contain different relative `path` and `sourceScopePath` values at different receiving scopes while representing the same immutable underlying occurrence. + +`before` and `after` are omitted when the corresponding presence Boolean is false. Null is not used as an absence sentinel. + +The semantic `op` is determined from presence, not merely copied from the authored Json Patch Entry: + +```text +before absent, after present -> add +before present, after present -> replace +before present, after absent -> remove +same exact before/after BlueId -> no Document Update +``` + +Therefore an authored object-member `replace` used as an upsert produces `op: add` when the member was absent. + +A Document Update Channel declares a scope-relative watched `path`. It matches when the changed path is equal to or below the watched path. + +### 6.4 Immediate Document Update cascade + +After one patch has been persistently applied and type soundness restored, its Document Update is delivered synchronously: + +```text +origin scope +nearest active ancestor +... +Root +``` + +At each receiving scope: + +1. discover and snapshot current matching Document Update Channels and Handlers; +2. process them in `(order, key)` order; +3. completely apply every matching Handler result before moving to the next receiving scope. + +The cascade does not wait for the application-event queue. A nested patch creates and completely processes its own cascade before the enclosing Handler result continues. + +The receiving chain is frozen when the update occurs. A handler may cause active-scope cut-off under §5.8; the current update still continues to higher receiving ancestors, but no later buffered effect from the cut-off source is applied. + +### 6.5 Application event emission + +When a Handler emits an event, the processor: + +1. validates the event as an admissible exact Blue node; +2. retains or establishes its exact identity; +3. records an internal EventOccurrence with the source scope and frozen ancestor chain; +4. appends the event to `ProcessResult.events` immediately if and only if the source scope is Root; +5. appends the occurrence to the invocation FIFO. + +The FIFO record is run state, not Blue content. It has no BlueId and is never returned. + +### 6.6 Triggered Event Channel + +When an EventOccurrence is dequeued, it is first delivered to matching Triggered Event Channels in its source scope, provided that source occurrence remains active, nonterminating, and nonterminated. + +Every delivery uses fresh channel and Handler snapshots. Events emitted by those handlers are appended to the FIFO after the currently dequeued occurrence. + +### 6.7 Embedded Node Channel + +After local Triggered handling, the same occurrence is offered to each active receiving ancestor in nearest-first order through Embedded Node Channels. + +The processor provides an exact channelized wrapper conceptually equivalent to: + +```yaml +type: Embedded Event Delivery +sourcePath: +event: + blueId: +``` + +The nested event is retained by exact identity. A receiving ancestor's Handler may explicitly emit the nested event or another event. Observation alone does not make it an event emitted by that ancestor. + +### 6.8 Lifecycle Event Channel + +The processor emits these lifecycle events: + +```text +Document Processing Initiated +Document Processing Terminated +``` + +Lifecycle Channels receive only processor-generated lifecycle events. Lifecycle handlers follow the same snapshot, result, queue, cut-off, and gas rules as other handlers. + +A deterministic failure or gas exhaustion rolls back lifecycle events with every other tentative effect. Fatal errors are returned as diagnostics; they are not separately emitted as committed application events. + +### 6.9 Event queue order + +The canonical queue order is FIFO by emission occurrence. For one occurrence: + +```text +source Triggered delivery +then nearest ancestor Embedded delivery +then next ancestor +... +then Root +``` + +Every caused patch and its full Document Update cascade completes synchronously before that event delivery continues. Events emitted during one delivery are appended to the FIFO and do not interrupt the current occurrence. + +The queue is drained in exactly one place: `DRAIN_INTERNAL_EVENTS` in §7.8. External-delivery helpers and lifecycle helpers enqueue events but MUST NOT independently drain the same queue. + +### 6.10 Processor-managed writes + +Processor-managed writes are classified as follows: + +| Write | Creates Document Update? | +|---|---:| +| Application Json Patch | Yes | +| Generated type-generalization write | Yes | +| Whole embedded child-root application patch | Yes | +| Processing Initialized Marker | No | +| External channel checkpoint | No | +| Processing Terminated Marker | No | + +Processor marker writes still pay pointer, identity, validation, and fixed processor gas. Lifecycle Channels are the observation mechanism for initialization and termination. + +--- + +## 7. Normative Processing Algorithm + +### 7.1 Run state + +One invocation maintains tentative state conceptually equivalent to: + +```text +RUN.inputRootBlueId +RUN.processingEvent +RUN.deliverySnapshot +RUN.acceptedNewDeliveries +RUN.acceptedStaleDeliveries +RUN.entryEmbeddedPaths +RUN.entryScopeRootIdentities +RUN.initializedScopes +RUN.activeScopes +RUN.cutOffScopes +RUN.terminatingScopes +RUN.terminatedScopes +RUN.eventQueue +RUN.rootEvents +RUN.contractSnapshots +RUN.validationProofs +RUN.openedNodeManifests +RUN.gasTrace +``` + +Implementation structures may differ. Observable result and canonical trace may not. + +### 7.2 Phase A — admission and direct Root state + +```text +1. Require admitted exact Root and event identities. +2. Require Root to be an object. +3. Begin the shared gas meter and charge processInvocation. +4. Read the direct Root terminated marker before application contracts. +5. If Root is already terminated, return status terminated, input Root, [], admitted gas. +6. Require the feeder snapshot to be bound to this exact Root revision and event. +``` + +Invalid provider content or unavailable required nodes are handled before or through the acquisition boundary in §12.4. + +### 7.3 Phase B — revalidate and classify external deliveries + +For each snapshot entry in canonical order: + +1. verify only the declared branch from Root to target; +2. freeze entry scope/path state as needed; +3. skip a path already cut off or under a direct terminated scope; +4. resolve the exact effective channel contribution snapshot; +5. skip when the snapshot no longer exists unchanged; +6. charge and evaluate `PRESELECTS` and `ACCEPTS`; +7. if rejected, record no accepted delivery and continue; +8. construct and freeze payload, checkpoint domain, and subject; +9. evaluate declared same-scope Channel dependencies; +10. freeze `handlerChannelKey` and `logicalDeliveryKey`; +11. compare the source checkpoint; +12. record the accepted raw source occurrence as `new` or `stale`; +13. after all entries are classified, group accepted-new sources under §3.3.3 and reject inconsistent groups before mutation. + +This phase is read-only. It does not initialize, execute Handlers, write checkpoints, or mutate Root. + +Because acceptance cannot depend on mutable Root state, classification is stable for the invocation. A later scope cut-off may still invalidate a previously classified occurrence. + +### 7.4 Phase C — must-understand preflight + +If no accepted new occurrence exists, the processor skips mutation and returns under §7.10. + +Otherwise, before the first mutation, it builds the initial participating closure from every accepted-new target and every declared ancestor. For each scope in Root-to-descendant order it: + +- checks direct terminated state; +- snapshots Process Embedded paths; +- recognizes every effective contract type and role; +- validates channel/Handler binding structure; +- validates required dispatch fields and portable limits; +- verifies that every selected external snapshot remains compatible. + +Unsupported or malformed runtime structure produces atomic failure before initialization. + +### 7.5 Phase D — process accepted-new deliveries + +Process accepted-new logical delivery groups in the canonical order of their first participating source occurrence. Raw source occurrences inside one group retain their original canonical order for checkpoint writes. + +Before each delivery: + +1. skip if its scope is cut off, removed, or under a terminated scope; +2. initialize every uninitialized active scope on Root-to-target chain in top-down order; +3. re-check cut-off and termination; +4. invoke the frozen logical delivery using its exact payload and frozen handler Channel; +5. apply every Handler result; +6. call `DRAIN_INTERNAL_EVENTS` exactly once to quiescence; +7. if the delivery scope remains active, nonterminating, and nonterminated, write every participating source checkpoint in canonical raw-source order; +8. call `DRAIN_INTERNAL_EVENTS` again only if a registered checkpoint extension legitimately emitted events; core checkpoint writes never do. + +If Root terminates, later external deliveries are skipped. + +### 7.6 Initialization ordering + +For target `/a/b/c`, uninitialized scopes are initialized: + +```text +/ +/a +/a/b +/a/b/c +``` + +Each scope's initialization lifecycle and caused internal event processing completes before the next descendant scope initializes. This prevents descendant effects from reaching an uninitialized ancestor. + +A scope initialized earlier in the same invocation is not initialized again. + +### 7.7 One external delivery + +For one accepted-new logical delivery group: + +```text +1. Use the frozen payload, handler Channel snapshot, and participating raw source snapshots. +2. Discover current post-initialization same-scope Handlers bound to handlerChannelKey. +3. Sort and freeze candidates. +4. For each candidate: + a. charge and evaluate its matcher; + b. if nonmatching, continue; + c. demand its executable body and declared dependencies; + d. execute with $event = payload and $processingEvent = original event; + e. apply its result under §4.12; + f. after every nested cascade, check active-scope cut-off. +5. Return to Phase D; do not drain the queue here. +``` + +The accepted channel may have no matching Handler. It is still a successful delivery and may be checkpointed. + +### 7.8 Internal event drain + +```text +function DRAIN_INTERNAL_EVENTS(): + while RUN.eventQueue is not empty: + occurrence = dequeue FIFO + + if source occurrence is active and not terminating and not terminated: + DELIVER_TRIGGERED_AT_SOURCE(occurrence) + + for receivingAncestor in occurrence.frozenAncestors nearest-first: + if receivingAncestor is active and not terminating and not terminated: + DELIVER_EMBEDDED_EVENT(receivingAncestor, occurrence) +``` + +Root has no ancestor and therefore cannot be cut off. Root termination does not erase occurrences that were already enqueued. The queue continues to quiescence under the ordinary active/nonterminating predicates and the shared gas limit. No new handler begins in Root after Root is marked terminating, and no later external delivery begins, but nonterminating descendant or intermediate scopes may finish reactions to occurrences already in the FIFO. + +Each delivery performs fresh channel and Handler discovery at that receiving scope, applies results synchronously, and may enqueue later occurrences. + +An occurrence emitted before its source is cut off continues to its frozen ancestors. Cut-off only stops new local work and unapplied buffered source effects. + +### 7.9 Phase E — final soundness and subscription validation + +Before returning success, the processor or its deterministic platform boundary MUST establish: + +- Root and every changed node are valid Blue Language nodes; +- the changed Root spine is type- and schema-sound; +- effective protected state was preserved; +- every changed effective contract type is supported; +- Process Embedded ancestry is acyclic and within limits; +- the changed subscription delta is finite, supported, and incrementally constructible; +- new activation intervals begin after the current external-order key; +- Root events satisfy the return limits. + +A deterministic failure in this phase rolls back the entire invocation. + +Transient inability to persist an already validated index delta is infrastructure suspension and commits nothing. + +### 7.10 Result selection + +If at least one accepted-new occurrence completed, result status is `success`, even when another candidate rejected, was stale, disappeared, or was cut off. + +If no new occurrence completed and at least one accepted occurrence was stale, result status is `stale`. + +If no current occurrence accepted, result status is `no-match`. + +`no-match` and `stale` return input Root and no events. They do not initialize or write checkpoints. + +An invocation that begins with a direct terminated Root returns `terminated`. + +### 7.11 Several matching scopes + +For: + +```text +Root +└── Emb1 + └── Emb2 + └── Emb3 +``` + +canonical external order is: + +```text +Emb3 +Emb2 +Emb1 +Root +``` + +The Emb3 external delivery and all of its caused updates/events complete before the Emb2 external delivery. Emb2 therefore sees Emb3's tentative changes. Root processes the external event last and sees all earlier tentative changes. + +The whole set is one atomic Root transition. A late failure rolls back earlier tentative work for the same external event. + +### 7.12 Exact locality + +Successful processing MUST NOT require semantic expansion or contract discovery of: + +- sibling embedded scopes outside selected branches; +- unrelated descendants; +- rejected external-channel bodies; +- nonmatching Handler bodies; +- unchanged descendant bodies needed only as known BlueIds; +- types, schemas, constants, or programs outside the demanded closure. + +A host MAY prefetch them, but they cannot alter semantic demands, results, or portable gas. + +--- + +## 8. Runtime Pointers, Patches, and Persistent Mutation + +### 8.1 Runtime Pointer + +A Blue Runtime Pointer is an RFC 6901 pointer over the current Root's abstract Blue node model. + +- `""` denotes Root and is forbidden as an application patch target. +- object segments use RFC 6901 escaping; +- list indices are canonical decimal without leading zero; +- `-` is permitted only for list `add` at the end; +- malformed escapes, empty trailing segments, or out-of-range indices are invalid. + +### 8.2 Json Patch Entry + +Core supports: + +```yaml +op: add | replace | remove +path: +val: # required for add/replace; absent for remove +``` + +Operations are applied in result order. A later patch observes all earlier tentative patches and cascades. + +`replace` on an object member is an upsert: the final member may be absent before the operation. `remove` of a missing member is invalid. + +The parent container of the final path segment MUST already exist and have the required object or list kind. Core patch semantics do not synthesize missing intermediate objects or lists. A runtime that wants to create a nested structure must add or replace an admitted complete subtree at an existing parent, or issue earlier patches that create each required parent explicitly. Arrays are never silently invented. + +### 8.3 Insertion normalization + +A value inserted by a patch or emitted as an event MUST: + +- be valid runtime Blue input with no root `blue` directive or unresolved alias; +- have no mixed `blueId` form; +- have one compatible payload kind; +- normalize list placeholders and scalar wrappers; +- preserve exact identity when it is already admitted; +- pay construction and identity work only when content is actually newly constructed or re-identified. + +### 8.4 Persistent copy-on-write + +For a patch to `/x/a` where `/x` is reference-backed: + +1. open only direct nodes on the path; +2. preserve unchanged siblings by exact child BlueId; +3. create the changed leaf or subtree; +4. rebuild `x`'s direct identity; +5. rebuild each changed ancestor to Root; +6. validate the affected closure; +7. deliver the Document Update. + +The old nodes remain immutable. Other references to old `x` are unchanged. + +### 8.5 Object operations + +A rebuilt object processes its complete direct helper map. One field change in a very wide direct object is therefore real linear direct-container work in every representation. + +Object field enumeration uses canonical Unicode code-point key order. Reserved Language and Contracts fields follow their specific rules. + +### 8.6 List operations + +List identity uses the Language fold: + +- append with a verified exact prior list identity recomputes only appended folds; +- replacement at index `i` recomputes the suffix from `i`; +- insertion or removal at `i` recomputes the affected result suffix; +- order and multiplicity are preserved. + +### 8.7 Snapshots + +Document Update `before` and `after` values are immutable exact-node snapshots. An absent side is represented only by the presence Boolean. + +A snapshot may retain a node by exact identity without recursively materializing it. A Handler pays only for content it actually reads. + +### 8.8 Boundary and cut-off validation + +Before every patch, the processor validates §5.7 against the executing scope's entry snapshot. + +After every patch and nested cascade, it checks whether an active scope root was removed or replaced and applies §5.8 before the next buffered effect. + +A patch to the same exact child identity is a no-op for occurrence continuity. An ordinary whole-child replacement with a different identity starts a new occurrence for later external events and does not join the current event. + +### 8.9 Effective protected-state validation + +The processor computes `EFFECTIVE_PROTECTED_STATE` before and after every application patch or generated type write. Pointer nonintersection alone is insufficient. + +If protected state changes outside the exact `Process Embedded.paths` exception, the invocation fails atomically with `ProtectedProcessorStateMutation`. + +### 8.10 Contract-changing patches + +A patch affecting any of these MUST trigger changed-closure recognition before further application execution: + +```text +/type +/contracts +an inherited type contribution +contracts/embedded/paths +another runtime-registered dispatch or subscription dependency +``` + +The processor re-establishes: + +- all effective contract types and roles in the changed closure; +- same-scope bindings; +- protected state; +- external subscription extraction; +- portable limits. + +Unsupported newly installed contract content cannot be committed and deferred to the next event. + +### 8.11 Direct-node limits + +A direct-node limit applies to every node that must be enumerated, validated, or rebuilt, including every ancestor on the changed spine. + +A larger exact node may still be carried opaquely by BlueId. An operation that needs its direct manifest fails deterministically with `DirectNodeLimitExceeded`. + +### 8.12 Cyclic sets + +Core runtime patches MUST NOT enter or structurally modify one member of a cyclic-set identity. A complete cyclic set may be replaced atomically as an already admitted new set. Otherwise processing fails with `CyclicSetMutationUnsupported`. + +Opaque cyclic-member edges are valid ordinary content and may remain untouched through copy-on-write reconstruction. They are not independent processing roots, external events, or embedded-scope roots. Admission, embedded-boundary validation, and patch planning MUST reject unsupported cyclic access before demanding a member body. + +--- + +## 9. Initialization, Lifecycle, and Termination + +### 9.1 Initialization gate + +A scope initializes only when an accepted-new delivery requires that scope to participate. + +These do not initialize a scope: + +```text +preselection false +channel rejection +all accepted occurrences stale +cut-off target +pre-existing terminated scope +capability failure +``` + +### 9.2 Initialization identity + +The Document Processing Initiated event carries the exact scope document as it existed immediately before initialization effects. That node may be carried as a pure reference or verified materialization; both forms are the same document and do not change processing or gas. No Source Document BlueId calculation is performed. + +### 9.3 Initialization algorithm + +For one uninitialized active scope: + +1. freeze its exact pre-initialization scope document and BlueId; +2. mark it `initializing` in run state; +3. create Document Processing Initiated; +4. deliver matching Lifecycle Channels and Handlers; +5. apply their results and enqueue emitted events; +6. call `DRAIN_INTERNAL_EVENTS` to quiescence; +7. re-check cut-off and termination; +8. if still active, nonterminating, and not terminated, Direct Write the Processing Initialized Marker; +9. mark it initialized for this invocation. + +The marker write creates no Document Update. If an ancestor replaces the scope during initialization reactions, no marker is written into the replacement. + +### 9.4 Initialization snapshot rule + +An accepted external channel snapshot remains frozen across initialization. Initialization may add, remove, or replace that channel in the current contracts map, but the already accepted delivery proceeds from its frozen snapshot unless the scope is cut off or terminated. + +Handler discovery occurs after initialization and sees the post-initialization effective contracts map. + +### 9.5 Termination request + +A ContractExecutionResult may request graceful termination with a deterministic application cause and optional reason. The cause explains why the successful business transition is ending; it is not a `graceful | fatal` execution mode. Runtime failure is represented only by a noncommitting failure status. + +The first request for a scope in one invocation wins. Later requests are ignored. A termination request is applied after that result's patches and emitted events have been recorded. + +### 9.6 Termination algorithm + +For one active nonterminating scope: + +1. freeze the first termination request; +2. mark the scope `terminating`; +3. create and deliver Document Processing Terminated; +4. apply lifecycle Handler results; +5. call `DRAIN_INTERNAL_EVENTS` to quiescence; its ordinary-delivery predicate excludes scopes marked `terminating`, so no new local Triggered or Embedded Handler begins in that scope, while event occurrences emitted before or during termination continue to nonterminating frozen ancestors; +6. re-check cut-off; +7. if the scope still exists as the same occurrence, Direct Write the Processing Terminated Marker; +8. mark the scope terminated and stop later local work. + +The marker creates no Document Update. + +A scope may stop reacting while already-emitted descendant event occurrences continue to higher frozen ancestors. + +### 9.7 Root termination + +When Root begins termination: + +- no later external delivery begins; +- the current result's already ordered patches and emissions complete according to §4.12; +- the termination lifecycle completes once; +- the Root termination marker write is attempted and metered under the normal rules; a committing termination requires it to complete; +- the committing status remains `success` because a new Root was produced. + +A later invocation on that Root returns `terminated` immediately. + +There is no fixed-price emergency closeout. If the marker write cannot fit within gas or violates a deterministic rule, the whole invocation rolls back. + +### 9.8 Deterministic failures + +A deterministic runtime failure does not gracefully terminate or write a processor marker. It aborts the tentative invocation, returns the input Root, returns no events, and reports the admitted gas and diagnostic. + +This keeps failure recovery separate from business termination and avoids partially committed fatal state. + +--- + +## 10. Checkpoints and Idempotency + +### 10.1 Checkpoint marker + +Each scope MAY contain one direct Channel Event Checkpoint at: + +```text +contracts/checkpoint +``` + +Conceptually: + +```yaml +contracts: + checkpoint: + type: Channel Event Checkpoint + entries: + : + domain: + blueId: + subject: + blueId: +``` + +Checkpoint state is direct processor state and is never inherited. + +### 10.2 Checkpoint domain + +A checkpoint entry is active only when its `domain` equals the current frozen channel's `checkpointDomainBlueId`. + +The default domain is the BlueId of a canonical domain node containing: + +```text +Contracts version tag +External Channel effective type BlueId +ordered source-contribution BlueIds +runtime-registered checkpoint-domain discriminator +``` + +A concrete channel type may define another exact domain derivation. It MUST be stable, representation-independent, and registered. + +Changing a channel's type or effective contributions at the same key therefore does not silently inherit an unrelated prior channel's stale state. + +### 10.3 Virtual empty state + +An absent checkpoint marker, absent raw key, or domain mismatch is treated as virtual empty state for newness evaluation. + +The processor MUST NOT create an empty marker before establishing that a delivery is accepted, new, and successful. + +### 10.4 Default exact-node subject + +The default checkpoint subject is the exact input event BlueId retained as a pure reference. + +A channel is stale when the current active entry has the same domain and the registered newness policy says the subject is not new. A concrete channel may use timeline predecessor, sequence, or another deterministic subject, but its policy and work are part of that exact runtime type. + +Checkpointing uses the exact input event BlueId by default; it does not run Source Document BlueId calculation. + +### 10.5 Atomic checkpoint write + +The checkpoint entry is Direct Written only after: + +- accepted Channel delivery; +- all matching external Handlers; +- all caused patches and Document Updates; +- all caused internal event processing; +- successful termination handling, if requested; +- confirmation that the delivery scope remains the same active occurrence. + +The checkpoint and every delivery effect commit together with Root. The write creates no Document Update. + +### 10.6 Checkpoint cleanup and domain retirement + +Checkpoint state is processor-owned and MUST NOT grow indefinitely after channels disappear or change semantic lineage. + +At final changed-closure recognition, the processor deterministically compares the direct checkpoint entries of each changed scope with the scope's final effective External Channels: + +- an entry whose raw channel key no longer exists is removed; +- an entry whose stored domain is not the current channel checkpoint domain is removed unless that exact runtime type defines an identity-bound migration accepted by this specification; +- an unchanged key with the unchanged domain is retained; +- cleanup is a processor Direct Write, creates no Document Update, and pays normal pointer, changed-direct-identity, validation, and `processorMarkerWritten` work; +- cleanup is tentative and rolls back with the invocation. + +A channel removed and later re-added therefore starts with virtual empty checkpoint state unless an exact registered migration rule says otherwise. + +### 10.7 Multiple occurrences and retry + +The same external event may be accepted by several channels in several scopes. Each `(scope occurrence, raw channel key, checkpoint domain)` has independent newness. + +After uncertain platform commit, the feeder reloads authoritative Root and revision: + +- if the new Root committed, checkpoints make previously completed occurrences stale; +- if the old Root remains, the event is recomputed from that Root; +- if another Root is current, a new revision-bound delivery snapshot is derived. + +The external event is never rewritten for retry. + + +--- + +## 11. Type Soundness, Generalization, and Subscription Indexability + +### 11.1 Post-write soundness + +After every successful patch, generated write, or processor Direct Write, the processor MUST restore the exact soundness obligations applicable to the changed closure before unrelated execution continues. + +For application and generated writes, this includes: + +- Blue Language node validity; +- fixed-value, type, schema, and collection compatibility; +- root-spine validity through every rebuilt ancestor; +- protected-state equality; +- supported effective contracts in the changed closure; +- valid Process Embedded structure and boundaries. + +Processor Direct Writes validate their own marker shape and the rebuilt Root spine but do not execute application Document Update Channels. + +### 11.2 Root-spine validation + +A deep embedded patch is not valid merely because the local child remains valid. Every changed ancestor from the patch location to Root MUST remain valid under its effective type and schema. + +Validation may retain unchanged child nodes by exact BlueId. It does not require transitive expansion of unchanged descendants unless their semantics are actually needed by a changed ancestor constraint. + +### 11.3 Type Generalization Policy + +A scope MAY contain a direct or inherited Type Generalization Policy at `contracts/generalization`. The effective policy is protected state. + +A policy contains ordered rules. Each rule identifies a path, mode, and optional floor type: + +```text +mode = nearest-valid-ancestor | reject +mustRemainSubtypeOf = optional exact type BlueId +``` + +The most specific matching path wins; ties use rule order. If no rule matches, the policy's `defaultMode` applies; absent default is `reject`. + +### 11.4 Nearest-valid-ancestor algorithm + +When a changed node no longer conforms to its current effective type and policy permits generalization: + +1. record the current explicit/effective type as candidate `T0`; +2. validate the changed node against `T0`; +3. if invalid, move to the immediate effective ancestor type `T1`; +4. test candidates upward one at a time; +5. reject a candidate violating `mustRemainSubtypeOf`; +6. choose the first valid candidate; +7. if no valid candidate exists before the floor or root of the chain, fail. + +Candidate order is exact type-chain order. A processor MUST NOT search unrelated types or choose a more general type when a nearer valid ancestor exists. + +### 11.5 Generated write order + +A generated type write is applied immediately after the patch that required it and before that patch's Document Update is delivered. + +The generated write: + +- is a processor-generated application-visible change; +- creates its own Document Update occurrence; +- is subject to protected-state validation; +- may trigger changed-contract recognition and subscription-delta validation; +- pays ordinary pointer, identity, validation, and update gas. + +Generated writes cannot specialize a node or invent a type not on the existing ancestor chain. + +### 11.6 Changed contract closure + +When type or contract contributions change, the processor MUST resolve every affected effective contract type before commit. An unsupported External Channel, Process Embedded marker, Handler, lifecycle contract, or executable extension makes the new Root invalid for Contracts processing and rolls back the invocation. + +Executable bodies remain lazy; recognition does not execute them. + +### 11.7 Subscription-delta validation + +Before a new Root can commit, the deterministic changed subscription delta MUST prove: + +- every changed Process Embedded exact path and collection path is valid; +- every present exact child, collection container, and direct collection member has the required object shape; +- every generated concrete collection-member path is unique and canonical; +- no declared embedded ancestry cycle exists; +- embedded depth, scope, key, and header limits hold; +- terminated-subtree pruning is deterministic; +- every changed External Channel type has supported subscription functions; +- its snapshot, keys, checkpoint domain, and activation interval can be derived; +- new intervals begin strictly after the current event order key; +- retired intervals are closed at the new Root revision; +- the incremental index delta is finite and canonical. + +The validator may examine only changed branches and dependencies plus retained index identities. It MUST NOT require a full recursive Root scan for every event. + +A deterministically non-indexable new Root fails with `SubscriptionSurfaceInvalid`. A transient failure to persist a valid delta is infrastructure suspension and commits nothing. + +--- + +## 12. Failure, Resource, Status, and Progress Semantics + +### 12.1 Statuses + +Core statuses are: + +| Status | Commits a new Root? | Meaning | +|---|---:|---| +| `success` | Yes | At least one accepted-new external occurrence completed. | +| `no-match` | No | No current External Channel accepted the event. | +| `stale` | No | At least one Channel accepted, but no accepted occurrence was new. | +| `terminated` | No | Root already had a valid direct terminated marker. | +| `invalid-processing-document` | No | Root or event was invalid before semantic execution. | +| `capability-failure` | No | A required runtime type or role was unsupported. | +| `runtime-fatal` | No | Deterministic processing failed after admission. | +| `gas-limit-exceeded` | No | The next canonical charge could not be admitted. | +| `portable-limit-exceeded` | No | A published portable structural or occurrence limit was exceeded. | +| `subscription-surface-invalid` | No | The input or resulting Root could not have a canonical subscription surface. | + +A committing Root termination is still `success`; a later invocation returns `terminated`. + +### 12.2 Diagnostic categories + +Appendix B defines exact diagnostic categories. A diagnostic MUST include enough deterministic context for conformance, such as scope path, contract key, runtime type, patch path, or limit name, without embedding host stack traces or nonportable messages. + +### 12.3 Admission and deterministic failure + +Malformed serialized input, a missing exact Root identity, or an invalid event may be rejected before the gas meter begins and therefore reports zero gas. + +After `processInvocation` is admitted, every deterministic semantic operation charges before work. A later capability, validation, patch, runtime, or limit failure returns the input Root, no events, and the gas admitted before the failure. + +There is no separate zero-gas tentative preflight ledger and no portable `attemptedWork` result. This makes expensive rejected work visible to the same deterministic budget. + +### 12.4 Resource acquisition boundary + +Core `PROCESS` operates on verified exact-node evidence. Deterministic execution MUST NOT perform ambient network I/O. + +An implementation MAY expose an attempt API: + +```text +PROCESS_ATTEMPT(root, event, verifiedEvidence) + -> Complete(ProcessResult) + | NeedsResources(sortedExactBlueIds) +``` + +`NeedsResources` is a suspension, not a `ProcessResult`: + +- it commits no Root, events, checkpoint, marker, progress, or portable gas; +- the host fetches and verifies direct nodes outside deterministic execution; +- retry starts from the exact input Root and event; +- hidden cache state MUST NOT turn the same explicit evidence set into a different attempt outcome. + +Provider transfer, direct-node verification, signatures, storage pages, and retry count are host work. Once an exact node is admitted, semantic inspection and new/changed identity work are charged normally and identically to inline content. + +### 12.5 Definitive missing content and invalid evidence + +A configured provider domain may report definitive `NotFound`; evidence may fail BlueId verification. These are host acquisition failures unless the exact runtime type deliberately treats one as application data. + +No implementation may convert unavailable, incomplete, or invalid evidence into semantic field absence. + +### 12.6 Gas exhaustion + +Every charge is admitted before the corresponding work. If the next charge would exceed `MAX_PROCESS_GAS`: + +- the failing charge is not added; +- no further runtime or lifecycle code runs; +- every tentative mutation, event, marker, checkpoint, and queue item is discarded; +- the result is `gas-limit-exceeded`, input Root, empty events, and already admitted gas. + +There is no fixed-price termination closeout. + +A repeated attempt against the same Root revision, event, environment, and gas limit produces the same status, trace prefix, and gas. + +### 12.7 Portable limits + +A limit known before the meter begins may be rejected with zero gas by the feeder or admission layer. A limit discovered after semantic execution begins returns `portable-limit-exceeded` with admitted gas. `NeedsResources` is never encoded as `ProcessResult.status`; it exists only as the alternate result of `PROCESS_ATTEMPT`. + +The diagnostic MUST identify the exact limit, such as: + +```text +MatchingDeliveryLimitExceeded +ParticipatingScopeLimitExceeded +DirectNodeLimitExceeded +EmbeddedDepthLimitExceeded +InternalEventLimitExceeded +PatchLimitExceeded +RuntimeLedgerLimitExceeded +``` + +### 12.8 Failure precedence + +When several errors are possible, the normative algorithm order decides. In particular: + +1. invalid Root/event admission precedes runtime discovery; +2. direct terminated state precedes application contract recognition; +3. delivery revalidation precedes Channel acceptance; +4. checkpoint comparison precedes initialization; +5. cut-off checks precede remaining buffered effects and marker writes; +6. gas exhaustion occurs at the first unadmitted canonical charge. + +Fixtures asserting one diagnostic MUST isolate the relevant failure or list acceptable categories explicitly. + +### 12.9 Revision-bound progress + +The feeder MUST record every terminal outcome only by compare-and-swap against the exact Root revision on which it was calculated. A progress-only terminal record (`no-match`, `stale`, failure, or gas exhaustion) cannot be committed after Root has changed. + +A Root-mutating `success` commits Root, Root events, subscription delta, and progress together. A failed compare-and-swap records nothing and triggers recomputation. + +### 12.10 External-event liveness + +A deterministic poison event MUST NOT cause unbounded automatic retries or permanently block all later external events. + +After one revision-bound terminal failure, the platform MUST either: + +- quarantine the event and advance according to declared platform policy; +- require explicit administrative retry; +- or change the Root/environment before retrying. + +The policy is audited outside Root but may not silently reinterpret a failed event as success. + +--- + +## 13. Canonical Gas Accounting + +### 13.0 Schedule status + +The counter vocabulary, ownership, formulas, and canonical trace order are normative for this implementation baseline. The numeric weights and portable-limit values are provisional pending calibration and are loaded from the bound gas manifest. Implementations MUST load or generate them from that artifact rather than scatter duplicated constants through runtime code. Final public Contracts 1.0 publication freezes the calibrated values once and regenerates every dependent fixture and package identity. + + +### 13.1 Governing principle + +Gas prices deterministic logical work, never the chosen materialization. + +For the same exact node `X`: + +```yaml +x: + a: 1 + b: 1 +``` + +and: + +```yaml +x: + blueId: X +``` + +must produce the same trace when the same logical fields are inspected and the same transition is performed. + +An existing exact node is cheap to carry. Content costs gas when it is inspected, compared, constructed, normalized, validated, or re-identified. + +### 13.2 One disjoint ledger + +```text +totalGas = + weighted processor counters + + weighted semantic counters + + weighted runtime counters +``` + +One logical unit increments one named counter. A reason tag never adds another numeric category. The same work MUST NOT be charged once as “admission” and again as “changed identity.” + +### 13.3 Canonical trace record + +In conformance mode, every admitted charge is appended before work as: + +```text +GasTraceEntry { + sequence + namespace + counter + quantity + weight + subtotal + scopePath? + contractKey? + logicalPath? + reason +} +``` + +Entries are ordered by the normative algorithm. `sequence` begins at zero and increases by one per trace entry. A charge with quantity greater than one remains one trace entry unless the rule explicitly requires per-occurrence entries. + +An ordinary API may return only `totalGas`, but a conforming implementation MUST be able to produce the exact trace for the fixture harness. + +### 13.4 Shared live-bounded meter + +Processor work, semantic Language work, external channels, Handlers, workflows, executable runtimes, and registered intrinsics share one meter. + +A runtime child meter receives the exact remaining budget. It admits every child charge live. Its ledger is merged once in original order. A runtime-local gas limit may only lower the available budget; it cannot replenish it. + +### 13.5 Processor counters and weights + +| Counter | Weight | +|---|---:| +| `processInvocation` | 50 | +| `deliverySnapshotEntry` | 5 | +| `scopeOpened` | 10 | +| `contractHeaderRecognized` | 2 | +| `channelCandidateTested` | 5 | +| `channelAccepted` | 5 | +| `handlerCandidateTested` | 5 | +| `handlerCall` | 50 | +| `scopeInitialization` | 1000 | +| `embeddedPathEntryRead` | 1 | +| `embeddedPathSegmentValidated` | 1 | +| `pointerSegmentTraversed` | 1 | +| `patchBoundaryChecked` | 2 | +| `patchAddOrReplace` | 20 | +| `patchRemove` | 10 | +| `documentUpdateDelivered` | 10 | +| `internalEventEnqueued` | 20 | +| `internalEventDequeued` | 10 | +| `triggeredEventDelivered` | 10 | +| `embeddedEventDelivered` | 10 | +| `rootEventRecorded` | 5 | +| `lifecycleDelivered` | 30 | +| `checkpointCompared` | 5 | +| `checkpointWritten` | 20 | +| `processorMarkerWritten` | 20 | +| `terminationRequested` | 10 | + +Rules: + +- `deliverySnapshotEntry` is charged once per retained entry revalidated by the processor. +- `scopeOpened` is charged once per distinct active scope occurrence in one invocation. +- `contractHeaderRecognized` is charged once per `(scopePath, key, ordered contribution identities)`. +- `embeddedPathEntryRead` is charged once for every effective entry read from `paths` or `collectionPaths` and once for every concrete direct member path generated from a collection declaration; +- every segment of an explicit declaration path, collection path, or generated concrete member path pays `embeddedPathSegmentValidated` when validated; +- opening a present collection target pays the ordinary semantic `nodeManifestOpened` charge, and enumerating its complete direct ordinary key set pays `objectMemberRead` once per direct member; collection enumeration is not free feeder folklore and is representation-invariant; +- a Channel or Handler candidate pays its test charge even when it rejects; +- a delivery counter (`documentUpdateDelivered`, `triggeredEventDelivered`, `embeddedEventDelivered`, `lifecycleDelivered`) is charged only for a matching Channel delivery, in addition to candidate tests; +- `rootEventRecorded` is charged only for Root emissions, not child emissions. + +### 13.6 Semantic counters and weights + +| Counter | Weight | +|---|---:| +| `nodeManifestOpened` | 1 | +| `objectMemberRead` | 1 | +| `listItemRead` | 1 | +| `textBlockExamined` | 1 | +| `textBlockConstructed` | 1 | +| `scalarComparison` | 1 | +| `integerLimbOperation` | 1 | +| `sortComparison` | 1 | +| `typeEdgeFollowed` | 1 | +| `schemaPredicateEvaluated` | 1 | +| `validationMemberExamined` | 1 | +| `validationProofReused` | 1 | +| `subtypeCandidateTested` | 5 | +| `nodeIdentityEstablished` | 1 | +| `objectMemberRebuilt` | 1 | +| `listFoldStepRecomputed` | 1 | +| `directIdentityHashBlock` | 1 | + +### 13.7 Manifest and immutable-read rules + +Opening the direct manifest of an exact node for the first semantic use in one invocation charges `nodeManifestOpened` once for that exact BlueId. A second semantic operation may reuse the retained immutable manifest without another manifest-open charge. + +Known-key object access charges `objectMemberRead` each time the normative algorithm examines that member, unless the value was explicitly bound and reused within the same algorithmic step. Complete enumeration charges once per direct member in canonical key order. + +List access charges `listItemRead` per position examined. + +Hidden caches from earlier invocations never reduce the canonical first-use trace. + +Provider-side BlueId verification is outside portable gas. Establishing the identity of new or changed content inside the invocation is charged under §§13.12–13.13. + +### 13.8 Text and scalar work + +One text block contains up to 64 Unicode code points. + +A full scan of Text `t` charges: + +```text +textBlockExamined += ceil(codePointLength(t) / 64) +``` + +A newly constructed Text charges the same block formula as `textBlockConstructed`. + +Lexicographic comparison examines code points until the first difference or the end of the shorter Text. Let `k` be the number of code points whose values are read from each operand, including the differing position when present. It charges: + +```text +scalarComparison += 1 +textBlockExamined += ceil(k / 64) for the left operand +textBlockExamined += ceil(k / 64) for the right operand +``` + +Length-only comparison after a fully equal prefix does not reread content. + +Exact Blue node identity equality may compare known BlueIds without scanning transitive content. Runtime value equality that is not exact Blue identity follows the runtime specification. + +### 13.9 Integer work + +Integers use a canonical unsigned base-`2^32` magnitude and separate sign. `L(x)` is at least 1 and otherwise the number of limbs. + +| Operation | `integerLimbOperation` quantity | +|---|---:| +| equality or ordering | `L(a) + L(b)` | +| addition or subtraction | `max(L(a), L(b)) + 1` | +| multiplication | `L(a) * L(b)` | +| division or remainder | `L(a) * L(b)` | +| GCD or `multipleOf` | `L(a) * L(b)` | +| LCM | GCD quantity plus multiplication quantity | + +The formula defines portable work, not a required host algorithm. + +### 13.10 Canonical sorting + +When processor semantics require sorting a candidate set, canonical gas is calculated as if using stable bottom-up merge sort: + +1. input order is canonical contract-key order or another explicitly defined order; +2. runs begin at width 1; +3. adjacent runs merge left-to-right; +4. run width doubles after each pass; +5. equal comparisons select the left element; +6. every comparator call charges `sortComparison` plus content work for compared fields. + +Implementations may use another physical algorithm but MUST report this canonical trace. + +External event ordering and subscription-index lookup are feeder work and do not use this processor counter. + +### 13.11 Type, contract, and validation work + +Effective contracts are merged ancestor-to-descendant: + +- charge `typeEdgeFollowed` for each traversed type edge; +- enumerate demanded contribution maps; +- inspect only registered dispatch fields; +- charge one `contractHeaderRecognized` for the effective snapshot. + +Validation charges: + +- `schemaPredicateEvaluated` per predicate; +- `validationMemberExamined` per collection member examined by `itemType`, `keyType`, `valueType`, `uniqueItems`, enum search, or another member-wise rule; +- `subtypeCandidateTested` per generalization/subtype candidate; +- Text and Integer work for scalar content examined. + +Within one invocation, an exact successful proof for: + +```text +(nodeBlueId, effectiveTypeBlueId, effectiveConstraintIdentity) +``` + +is charged in full once. Later logical reuse increments `validationProofReused` once and does not repeat predicate/member counters. Cross-invocation caches are physical optimization only and do not remove the current invocation's first full proof. + +### 13.12 Identity establishment + +Every new exact node, including an empty list, charges: + +```text +nodeIdentityEstablished += 1 +``` + +For a new or rebuilt non-list node: + +```text +objectMemberRebuilt += direct helper-map members processed +directIdentityHashBlock += ceil((N + 9) / 64) +``` + +`N` is the UTF-8 byte length of the exact RFC 8785 canonical direct identity input hashed for that node. Transitive child bodies are replaced by their exact bounded canonical Base58 child BlueId strings before `N` is measured. Direct keys, `name`, `description`, and inline scalar `value` contribute because the Language BlueId algorithm hashes them directly. + +This is actual changed/new identity work. Carrying an existing exact node never pays it again. + +### 13.13 List identity + +For a new or changed list: + +- full construction charges one `listFoldStepRecomputed` per result element; +- append from a verified prior exact list identity charges appended steps only; +- replacement at index `i` charges the result suffix from `i`; +- insertion/removal at `i` charges the affected result suffix. + +The fixed list-cons hash input is represented by the fold counter and is not charged again as `directIdentityHashBlock`. + +### 13.14 Runtime ledger composition + +Each executable runtime type publishes exact named counters and weights in its own specification and runtime registry. + +Runtime construction work and semantic identity admission are distinct: + +```text +A concrete compute runtime creates a 100-member object: + that runtime charges members produced. + +The value crosses a Blue output/patch boundary: + Contracts/Language charges node identity and direct-container work. +``` + +Passing an existing exact Blue node charges only the runtime access/carry work actually defined by that runtime; it does not recursively size or reconstruct the node. + +### 13.15 Patch trace + +A successful patch charges, in order: + +```text +patchBoundaryChecked +pointerSegmentTraversed for each segment +patchAddOrReplace or patchRemove +runtime construction, when the value was newly built +identity establishment for changed leaf and every rebuilt ancestor +post-write type/schema/generalization work +Document Update candidate tests and matching deliveries +downstream Handler/runtime work +``` + +It does not charge unchanged transitive descendants behind known child BlueIds. + +### 13.16 Event and checkpoint trace + +Emitting an existing exact event has no recursive size charge. A newly constructed event pays runtime construction and semantic identity admission before `internalEventEnqueued`. + +A Root emission additionally pays `rootEventRecorded`. + +Checkpoint comparison pays `checkpointCompared` and the exact subject policy work. A checkpoint write pays `checkpointWritten`, marker pointer work, direct changed identity, and validation. It creates no Document Update. + +### 13.17 Zero-gas physical work + +The following consume zero portable Contracts gas: + +```text +provider lookup and transfer +provider BlueId verification +cache hit, miss, fill, or eviction +storage page/chunk access +physical prefetch +allocation and host copying +hash-cache lookup +transport serialization +subscription-index maintenance/query +external-source completeness queries +external event sorting +failed compare-and-swap and recomputation +``` + +Hosts may meter, bill, or quota them separately. + +### 13.18 Representation example + +Suppose: + +```yaml +x: + a: 1 + archive: + blueId: <25-MiB-archive> +``` + +and an equivalent Root has `x` collapsed to its BlueId. For: + +```yaml +op: replace +path: /x/a +val: 2 +``` + +both forms perform and charge the same semantic trace: + +1. open Root direct manifest; +2. open `x` direct manifest; +3. traverse `/x/a`; +4. admit scalar `2`; +5. rebuild `x` using the unchanged archive BlueId; +6. rebuild ancestors to Root; +7. validate changed closure; +8. deliver caused updates and events. + +The archive body is neither demanded nor charged. A one-million-field direct `x` remains expensive in both forms because its direct manifest is real identity work. + +### 13.19 Worked processor subtotal (informative) + +Assume one already admitted external event has: + +```text +one retained raw delivery +two participating scopes +four effective contract headers +one Channel candidate that accepts +one Handler candidate that executes +one two-segment patch path /x/a +no initialization in this example +``` + +The processor-counter subtotal before semantic reads, runtime work, identity rebuilding, validation, updates, checkpoints, or sorting is: + +```text +processInvocation 1 * 50 = 50 +deliverySnapshotEntry 1 * 5 = 5 +scopeOpened 2 * 10 = 20 +contractHeaderRecognized 4 * 2 = 8 +channelCandidateTested 1 * 5 = 5 +channelAccepted 1 * 5 = 5 +handlerCandidateTested 1 * 5 = 5 +handlerCall 1 * 50 = 50 +pointerSegmentTraversed 2 * 1 = 2 +patchBoundaryChecked 1 * 2 = 2 +patchAddOrReplace 1 * 20 = 20 + ---- +processor subtotal 172 +``` + +`172` is deliberately only a subtotal. The complete gas also includes the exact semantic and runtime counters actually caused by the concrete nodes and handler. Conformance fixtures, not this illustrative example, define complete exact traces. + +--- + +## 14. Determinism, Security, and Portable Limits + +### 14.1 Deterministic execution + +Contract behavior MUST NOT depend on: + +- wall-clock time; +- randomness; +- ambient network reads; +- CPU speed or thread scheduling; +- host object identity; +- cache warmth; +- database row order; +- locale-sensitive comparison; +- noncanonical map iteration; +- unspecified numeric behavior. + +External time and actor attribution enter only through the immutable event and feeder evidence fixed before processing. + +### 14.2 Read-only values + +Event nodes, snapshots, dispatch snapshots, and runtime context are read-only. All application mutation occurs through Json Patch Entries. All application event output occurs through the normalized result. + +A host MUST NOT require recursive cloning to enforce read-only behavior. Immutable identity-preserving values are sufficient. + +### 14.3 Trust boundary + +The processor trusts the managing feeder to supply a complete revision-bound snapshot and correct external-order evidence. It revalidates every selected branch and channel identity but does not independently rescan the complete subscription surface. + +The trust boundary is: + +| Input or claim | Core treatment | +|---|---| +| Root, event, type, body, and demanded node content | Must have verified exact BlueId evidence. | +| Delivery path and channel contribution identity | Revalidated against the admitted Root and retained snapshot. | +| Completeness of the preselected occurrence set | Feeder/platform obligation; an omission is nonconformance. | +| Cross-source external order | Bound by the exact policy identity and completeness evidence under §3.6. | +| Runtime semantics | Selected by exact runtime-type BlueId and registry binding. | +| Authorization or mandate eligibility | Feeder/provider responsibility unless a runtime type adds deterministic checks. | +| Cache, provider transport, database order, host scheduling | Never trusted as semantic input. | + +The processor fails closed on invalid or incomplete evidence. It does not reinterpret unavailable content as absence and does not silently broaden its trust in a warm cache or provider. + +### 14.4 Portable limits + +| Limit | Value | +|---|---:| +| `MAX_PROCESS_GAS` | 100,000 | +| Effective contracts in one participating scope | 8,192 | +| External Channels in one scope | 2,048 | +| Handlers bound to one delivery | 4,096 | +| Subscription keys from one Channel | 256 | +| Preselected external occurrences for one event | 1,024 | +| Participating scopes for one event | 4,096 | +| Combined concrete Process Embedded child paths in one scope | 4,096 | +| Process Embedded declaration entries (`paths` + `collectionPaths`) | 4,096 | +| Embedded depth | 256 | +| Runtime Pointer segments | 256 | +| Normalized Runtime Pointer UTF-8 bytes | 4,096 | +| Contract-key Unicode code points | 256 | +| Contract-key UTF-8 bytes | 1,024 | +| Direct object entries materialized/rebuilt | 16,384 | +| Direct list items materialized/rebuilt | 16,384 | +| Direct canonical identity input bytes | 1,048,576 | +| Type-chain edges | 256 | +| Patches in one ContractExecutionResult | 1,024 | +| Events in one ContractExecutionResult | 1,024 | +| Internal EventOccurrences in one invocation | 8,192 | +| Root events returned | 4,096 | +| Nested Document Update cascade depth | 256 | +| Runtime child-ledger counter kinds | 256 | +| Direct object-key Unicode code points | 4,096 | +| Direct inline identity Text code points | 262,144 | + +These are structural bounds, not promises that maximum-size valid structures fit under `MAX_PROCESS_GAS`. Gas is the operative work ceiling. + +Limits fall into two classes: + +```text +preflight structural limits + may be established before semantic execution and fail with the named + portable-limit diagnostic, possibly with zero gas under §12.7; + +execution safety limits + stop pathological growth during processing but may be dominated by the + earlier gas ceiling under the bound manifest. +``` + +The release manifest and fixtures MUST define failure precedence for every limit. A listed safety limit is not a promise that its dedicated diagnostic is independently reachable under every gas schedule. If the calibrated gas ceiling necessarily triggers first, `gas-limit-exceeded` is the conforming result. A future manifest with different calibrated values may make the structural diagnostic reachable without changing the semantic rule. + +A host MAY impose lower operational quotas. It MUST NOT raise the portable gas or structural limits and still claim the same portable Contracts 1.0 execution environment unless the higher values are bound by a distinct environment identity and the resulting behavior is not presented as portable Contracts 1.0 conformance. + +The direct-container limit applies to every rebuilt ancestor. A larger exact node can be carried opaquely, but an operation requiring its direct manifest fails. + +### 14.5 Bounded feeder work + +The feeder MUST also bound: + +```text +active index entries per managed Root +subscription-key bytes +external event-header demand +preselection work +activation intervals +retained delivery snapshot size +``` + +Hosted numeric quotas may be stricter than the portable processor limits. They MUST be declared before admission and must not change the semantic result of an admitted event. + +### 14.6 Authoring guidance + +Authors SHOULD: + +- use bounded-fanout structures for large mutable collections; +- place large workflow bodies, constants, and templates behind BlueId references; +- keep External Channel headers and subscription keys small; +- put mutable business conditions in Handlers, not External Channel acceptance; +- avoid broad events matching thousands of scopes; +- preserve event/gas headroom for ancestor reactions; +- model independent shared objects as autonomous roots; +- use stable object keys for dynamic embedded collections; +- avoid list positions as process-occurrence identities; +- instantiate reusable process modules with explicit local Channel bindings rather than implicit parent lookup. + +A useful lower-bound estimate before type, schema, text, sorting, runtime, mutation, and identity work is: + +```text +base scan gas ~= + 50 # processInvocation + + 5 * preselected raw occurrences + + 10 * distinct participating scopes + + 2 * recognized effective contract headers + + 5 * Channel and Handler candidates tested +``` + +The exact trace is defined by §13 and the bound manifest. This estimate is authoring guidance only, but it makes clear that the structural maxima are not practical per-event targets. + +### 14.7 Locality conformance + +A processor is not conforming to the locality rules merely because it returns correct gas while still requiring a complete graph materialization. Conformance locality fixtures record exact semantic node demands. A processor MUST be able to complete them without demanding listed unrelated sibling bodies. + +An implementation may physically prefetch those bodies, but they must remain outside the semantic-demand report and cannot be required for success. + +--- + +## 15. Conformance Vectors + +The prose rules, runtime registry, gas manifest, and machine-readable fixture package form one conformance surface. A conforming implementation MUST pass every vector and every fixture bound by the release manifest. + +The 100 vectors are organized by the processor phase or invariant they exercise. One executable fixture may cover several vectors. + +### 15.1 Representation and locality + +- **C-REP-01.** Inline and pure-reference forms of the same Root produce the same status, resulting Root, Root events, semantic demands, counter trace, and gas. +- **C-REP-02.** A patch inside a collapsed branch demands only nodes on the path and semantic dependencies, not sibling bodies. +- **C-REP-03.** Warm/cold cache, batching, prefetch, and physical segmentation do not change portable results or gas. +- **C-REP-04.** Existing large exact values can be carried, emitted, and checkpointed without recursive size work. +- **C-REP-05.** Newly constructed large values pay runtime construction and semantic identity work. +- **C-REP-06.** A wide direct ancestor is charged and limited in every representation. +- **C-REP-07.** An early list edit pays the recomputed suffix; append pays only the delta when prior identity is available. + +### 15.2 Feeder, subscriptions, and external order + +- **C-FEED-01.** The subscription index is revision-complete before event selection. +- **C-FEED-02.** `ACCEPTS => PRESELECTS` and `PRESELECTS => key intersection` hold for every portable External Channel. +- **C-FEED-03.** External Channel acceptance cannot depend on mutable Root state. +- **C-FEED-04.** Physical index false positives are filtered before canonical ordering and limits. +- **C-FEED-05.** An omitted true preselection is feeder nonconformance, not `no-match`. +- **C-FEED-06.** A new Channel begins strictly after the event that introduced it. +- **C-FEED-07.** Removed and re-added semantic Channel contributions create a new activation interval. +- **C-FEED-08.** All deliveries of one event complete before a later external event begins. +- **C-FEED-09.** Nonmutating terminal progress is compare-and-swap bound to the exact Root revision. +- **C-FEED-10.** Repeated deterministic poison events are quarantined rather than retried forever. +- **C-FEED-11.** A concrete channel-specific target key may route one event to one collection member even when many members reuse the same external source; target derivation remains runtime-specific. + +### 15.3 Routing, discovery, snapshots, and initialization + +- **C-DISC-01.** Direct terminated state is checked before application contract recognition. +- **C-DISC-02.** Every effective contract type in the initial participating closure is recognized before first mutation. +- **C-DISC-03.** Unselected executable bodies remain collapsed. +- **C-DISC-04.** Effective contracts use ordered contribution identities rather than a synthetic merged BlueId. +- **C-DISC-05.** A Handler snapshot survives same-delivery contract mutation. +- **C-DISC-06.** Contract/type changes are re-recognized before commit. +- **C-INIT-01.** `no-match` and all-stale processing do not initialize. +- **C-INIT-02.** Ancestors initialize Root-to-target before descendant processing. +- **C-INIT-03.** Accepted Channel/payload/checkpoint snapshot remains frozen across initialization. +- **C-INIT-04.** Handler discovery after initialization sees post-initialization contracts. +- **C-INIT-05.** Initialization marker writes do not create Document Updates. +- **C-ROUTE-01.** The default handler Channel equals the accepted source Channel and preserves existing one-source behavior. +- **C-ROUTE-02.** A declared peer same-scope Channel may be frozen as handler target without being externally evaluated or checkpointed. +- **C-ROUTE-03.** Exact absent and present-non-Channel target lookups remain distinguishable; unavailable or undeclared evidence fails closed. +- **C-ROUTE-04.** Several fresh sources with the same logical delivery key, target, and payload execute handlers once and checkpoint every source only after success. +- **C-ROUTE-05.** A stale source does not piggyback on a fresh source in the same logical group. +- **C-ROUTE-06.** Group target or payload disagreement fails atomically before mutation. +- **C-INIT-06.** The initialization marker and initiated event carry the exact initial scope document; inline and pure-reference forms yield the same Root, lifecycle behavior, gas, and trace. + +### 15.4 Embedded scopes, updates, and events + +- **C-EMB-01.** External deliveries are ordered deeper-first, then path, order, and key. +- **C-EMB-02.** One external event produces one atomic Root transition across all selected scopes. +- **C-EMB-03.** Unrelated embedded branches are not semantically demanded. +- **C-EMB-04.** A parent may replace an immediate child root but may not patch inside it. +- **C-EMB-05.** Strict-ancestor patches intersecting child roots are rejected. +- **C-EMB-06.** Active-scope replacement cuts off remaining buffered effects and marker/checkpoint writes. +- **C-EMB-07.** Re-adding a path does not resurrect the old occurrence in the current invocation. +- **C-EMB-08.** `collectionPaths` expands direct object members into concrete embedded scopes in canonical key order; the collection container is not implicitly a scope. +- **C-EMB-09.** A collection target must be object-compatible; lists, non-object members, wildcard syntax, reserved-field traversal, and cyclic-member boundaries fail closed. +- **C-EMB-10.** A collection member added by event `E` does not participate in `E` and begins its subscription interval strictly after `E`. +- **C-EMB-11.** Removing a collection member retires its occurrence; re-adding the same key creates a fresh interval and checkpoint lineage. +- **C-EMB-12.** Exact paths, collection declarations, and generated concrete member paths must not overlap or duplicate one another. +- **C-EMB-13.** The same exact child node at two collection keys creates two independent scope occurrences with independent checkpoints and state transitions. +- **C-EMB-14.** Embedded scope contracts are same-scope and self-contained; parent and ancestor contract keys are not imported or searched. +- **C-EMB-15.** A local Channel bound inline and the same exact Channel bound by pure BlueId reference produce identical processing, subscription, checkpoint, gas, and trace behavior. +- **C-EMB-16.** Changing a parent Channel does not silently rebind an existing child; a newly created child may explicitly use the new binding. +- **C-UPD-01.** Every successful application patch creates one origin-to-Root Document Update cascade. +- **C-UPD-02.** Presence Booleans preserve add/remove identity without null sentinels. +- **C-UPD-03.** Current update propagation continues on its frozen chain after source cut-off. +- **C-EVT-01.** Source Triggered handling precedes nearest-to-farthest ancestor Embedded handling. +- **C-EVT-02.** Events emitted during delivery are appended FIFO and do not interrupt the current occurrence. +- **C-EVT-03.** Child emissions are not returned unless Root explicitly emits. +- **C-EVT-04.** Duplicate equal event nodes remain distinct occurrences and Root outputs. +- **C-EVT-05.** The internal queue is drained exactly once by the normative owner. + +### 15.5 Checkpoints, lifecycle, and protected state + +- **C-CHK-01.** Checkpoint newness is evaluated before initialization. +- **C-CHK-02.** Absent checkpoint state is virtual and no empty marker is created for stale/rejected delivery. +- **C-CHK-03.** Checkpoint entries bind raw key, domain, and subject. +- **C-CHK-04.** Replacing a Channel at the same key changes the active checkpoint domain. +- **C-CHK-05.** Checkpoint write commits only after complete delivery and queue processing. +- **C-CHK-06.** Retry after uncertain commit is idempotent against authoritative Root. +- **C-CHK-07.** Removed channels and changed checkpoint domains are deterministically cleaned from processor checkpoint state without a Document Update. +- **C-LIFE-01.** Initiated lifecycle precedes initialized marker. +- **C-LIFE-02.** First termination request wins and lifecycle/marker occur at most once. +- **C-LIFE-03.** Scope replacement during lifecycle prevents marker write into replacement. +- **C-LIFE-04.** Gas failure during termination rolls back the entire invocation. +- **C-PROT-01.** Application patches cannot directly or indirectly alter protected state. +- **C-PROT-02.** Only the Process Embedded declaration fields `paths` and `collectionPaths` may change under their exact protected-state exception. + +### 15.6 Soundness, failure, indexability, and bounded loops + +- **C-SND-01.** Every changed ancestor to Root is type- and schema-validated. +- **C-SND-02.** Nearest-valid type generalization is deterministic and bounded by policy. +- **C-SND-03.** Generated type writes create Document Updates and are re-recognized. +- **C-SND-04.** Cyclic-set member mutation is rejected. +- **C-CYC-01.** A pure cyclic-set member is rejected as an independently mutable processing Root before provider demand. +- **C-CYC-02.** A pure cyclic-set member is rejected as a top-level processing event before provider demand. +- **C-CYC-03.** `Process Embedded` cannot terminate at or traverse through an opaque cyclic-member edge. +- **C-CYC-04.** An ordinary Root can preserve an untouched opaque cyclic-member edge while unrelated selected processing succeeds without opening it. +- **C-IDX-01.** A new Root with invalid embedded path, cycle, unsupported subscription extraction, or excess limit rolls back. +- **C-IDX-02.** Valid subscription delta is incremental and new intervals start after the current event. +- **C-FAIL-01.** Deterministic failure returns input Root, no events, and admitted gas. +- **C-FAIL-02.** Transient resource suspension commits no state, progress, events, or portable gas. +- **C-FAIL-03.** Gas exhaustion returns the canonical trace prefix and is deterministic on retry. +- **C-FAIL-04.** Compare-and-swap conflict commits nothing and is outside portable gas. +- **C-FAIL-05.** `PROCESS_ATTEMPT` may return `NeedsResources`, but no completed `ProcessResult` uses `needs-resources` as a status. +- **C-LOOP-01.** An internal event cycle is stopped by the shared gas limit and rolls back Root and Root events. + +### 15.7 Gas and executable-runtime integration + +- **C-GAS-01.** Every processor and semantic counter has an exact weight and microfixture. +- **C-GAS-02.** Charges are admitted before work and the failing charge is absent on exhaustion. +- **C-GAS-03.** Manifest opening and validation proof reuse follow run-local canonical memo rules. +- **C-GAS-04.** Text comparison, Integer limbs, and canonical sorting produce exact traces. +- **C-GAS-05.** Direct identity blocks charge only new/changed direct identity, never unchanged transitive content. +- **C-GAS-06.** Runtime child ledgers are live-bounded and merged exactly once. +- **C-GAS-07.** Executable-runtime representation state is unobservable and recursive boundary-size charging is absent. +- **C-GAS-08.** Provider verification and transport are outside portable gas. + +### 15.8 End-to-end results + +- **C-E2E-01.** A complete successful Root transition fixture asserts exact status, resulting document, Root event order, named trace, total gas, and semantic demands. +- **C-E2E-02.** A deep embedded delivery fixture asserts the same complete result dimensions and returns an empty public event sequence when Root emits nothing. +- **C-E2E-03.** An inline/reference representation matrix produces the exact same complete end-to-end result and trace. + +### 15.9 Machine-readable fixture package + +The implementation-baseline fixture package is bound to the exact runtime registry manifest and the exact `blue-contracts/gas/1.0` manifest. It publishes: + +- 96 executable behavior fixtures covering all 100 vectors in §§15.1–15.8; +- feeder/platform and revision-bound commit fixtures; +- locality semantic-demand assertions; +- 58 exact gas microfixtures and composite gas fixtures; +- a vector-to-fixture coverage map; +- a fixture schema and scripted runtime registry bindings; +- deterministic file digests and package identity. + +The fixture envelope is: + +```yaml +schema: blue-contracts-fixture/1.0 +id: +vectors: [C-...] +category: +operation: process | process-attempt | platform | gas-micro +input: + root: + event: + feeder: + provider: + runtime: +expected: + assertions: +``` + +`input.feeder.deliverySnapshot` is derived environment evidence. It is not caller-authored Blue content and is not a third semantic input to `PROCESS`. The harness independently verifies that it equals the canonical snapshot for the supplied Root revision, event, activation intervals, external-order policy, and runtime registry. + +The scripted fixture runtime is a conformance instrument, not a portable application runtime. Its control vocabulary and trace projections MUST be closed, versioned, and defined by the fixture schema and harness. Unknown control fields or projections fail closed. + +The implementation-baseline fixture-package identity is: + +```text +sha256:16392301655431695df6a7cc142a7e388e426c382bf4e3c5f06ddfafb8efecdc +``` + +The package contains 100 normative vectors, 96 behavior fixtures, and 58 gas fixtures. The behavior-fixture count is not required to equal the vector count because one executable fixture may cover several inseparable normative assertions. + +--- + +## 16. Worked Examples + +### 16.1 Lazy selected workflow + +```yaml +contracts: + buyerChannel: + type: Example External Channel + source: + blueId: + + approve: + type: Example Lazy Operation Handler + channel: buyerChannel + operation: approve + steps: + blueId: + + cancel: + type: Example Lazy Operation Handler + channel: buyerChannel + operation: cancel + steps: + blueId: +``` + +For an `approve` event, the processor recognizes every effective contract type and the relevant dispatch fields. It opens `` only after the approve Handler matches. `` remains collapsed. + +### 16.2 One deep external delivery + +```text +Root +├── unrelatedA +├── Emb1 +│ ├── unrelatedB +│ └── Emb2 +│ ├── unrelatedC +│ └── Emb3 +└── unrelatedD +``` + +The feeder index identifies one preselected Channel at `/Emb1/Emb2/Emb3`. The processor demands: + +```text +Root direct manifest +Emb1 direct manifest +Emb2 direct manifest +Emb3 direct manifest +required effective type/contract headers on that chain +selected Handler body and data it reads +changed nodes on the path back to Root +``` + +It does not semantically demand `unrelatedA`, `unrelatedB`, `unrelatedC`, or `unrelatedD` bodies. + +### 16.3 Root-only events + +Suppose: + +```text +Emb3 receives external X +Emb3 emits A +Emb2 observes A and emits B +Emb1 observes B and emits C +Root observes C, patches /status, and emits nothing +``` + +The successful result is: + +```text +ProcessResult.document = Root' +ProcessResult.events = [] +``` + +If Root explicitly emits `D`, the result is: + +```text +ProcessResult.events = [D] +``` + +### 16.4 Several selected scopes + +If the same event is preselected at: + +```text +/Emb1/Emb2/Emb3 +/Emb1/Emb2 +/Emb1 +/ +``` + +the external order is: + +```text +Emb3 -> Emb2 -> Emb1 -> Root +``` + +The complete Emb3 delivery, update cascades, and internal event propagation reach quiescence before Emb2 receives the original event. Root receives the original event last. One late failure rolls the complete Root transition back. + +### 16.5 Reference-backed patch + +Initial logical content: + +```yaml +x: + blueId: +``` + +where `X` directly contains: + +```yaml +a: 1 +archive: + blueId: +``` + +Patch: + +```yaml +op: replace +path: /x/a +val: 2 +``` + +The processor opens Root and `X`, preserves `` by BlueId, creates `X2`, rebuilds Root, and never demands the archive body. + +### 16.6 Active-scope cut-off + +A child Handler returns: + +```text +patch /child/value +patch /child/other +emit ChildCompleted +``` + +The first patch causes a Root Document Update Handler to replace `/child` as a whole. The old child occurrence is cut off. The replacement and already applied first patch/cascade remain tentative, but the old child's second patch, `ChildCompleted`, checkpoint, and later marker writes are discarded. + +An event that the old child had already emitted before replacement still continues through its frozen ancestor chain. + +### 16.7 Checkpoint domain + +Channel version A at key `buyer` processes event `E`: + +```text +entries.buyer.domain = domain(A) +entries.buyer.subject = E +``` + +A later Root replaces the effective channel contributions at `buyer` with semantically different version B. `domain(B) != domain(A)`, so B sees virtual empty checkpoint state. It does not accidentally inherit A's stale subject. + +### 16.8 New subscription frontier + +Event `A@100` adds a new external-source Channel while that source already contains `B@50`. + +The new interval begins strictly after `A@100`. `B@50` is not delivered retroactively. An initial Root admission that intends historical replay must declare a historical frontier explicitly. + +### 16.9 Deterministic order across independent sources + +Assume one Root subscribes to an identity-provider source and a bank source. Their concrete source-local keys are different, but the managed environment binds one global policy: + +```text +primary: provider-assigned microsecond time +secondary: stable source identity +tertiary: source-local entry order +``` + +The identity provider reports event `I` at time `100`, and the bank reports event `B` at time `99`. Even if `I` arrives first, the feeder waits for both completeness frontiers and processes: + +```text +B -> I +``` + +If both have primary time `100`, the policy's stable source-identity tie-breaker determines one order on every platform. Arrival order is irrelevant. The exact tuple above is illustrative; a concrete ecosystem publishes and identity-binds its own total-order policy under §3.6. + +### 16.10 Autonomous linked Root + +If two managed documents must observe one independently evolving object, that object is another managed Root: + +```text +SharedRoot processes and commits its own events. +RootA observes SharedRoot events later. +RootB observes SharedRoot events later. +``` + +It is not duplicated as one owned embedded occurrence that magically mutates under both parents. + +--- + +## Appendix A — Core Runtime Type Catalog + +The canonical runtime registry is the authority for exact source nodes and BlueIds. The definitions below state required semantics and intended identity-bearing fields. + +### A.1 Contract + +Base type for all runtime declarations under `contracts`. + +Required semantics: + +```text +order: optional Integer, default 0 +``` + +A concrete subtype declares one exact runtime role. + +### A.2 Channel + +Base Contract subtype that produces one channelized delivery or rejects an event. + +Processor-managed Channel subtypes receive only their processor event family.

Only these two declaration fields are application-changeable under the protected-state exception. The exact canonical registry node remains the authority for identity-bearing descriptions and BlueId. + +### A.8 Processing Initialized Marker + +Direct processor state at `contracts/initialized`: + +```yaml +name: Processing Initialized Marker +document: + description: > + Exact pre-initialization scope document.

Helpers enqueue and return. + +### D.15 Do not confuse hosted work with portable gas + +Provider bytes, signatures, storage, index maintenance, and CAS retries are host resources, not portable Contracts counters. + +### D.16 Do not treat BlueId derivation paths as different identifier types + +Contracts uses exact BlueIds for Root, event, checkpoints, bodies, and snapshots. The Language may derive a BlueId directly from an exact node or through the Source Document pipeline. The resulting identifier is the same BlueId kind. + +### D.17 Do not copy an authored upsert operation into Document Update blindly + +An authored `replace` on an absent object member is an upsert, but the resulting Document Update has semantic `op: add` because the member was absent before and present afterward. + +### D.18 Do not merge independent external sources by arrival order + +Cross-source order must satisfy the totality, per-source consistency, stable tie-break, and completeness laws in §3.6. Network arrival order, query order, and database insertion order are not semantic evidence. + +### D.19 Do not embed contract entries + +`Process Embedded` declarations must not traverse `/contracts`. Contract entries are runtime declarations of their containing scope, not child scopes. + +### D.20 Do not interpret lists or wildcards as embedded collections + +`/lessons/*` has no wildcard meaning, and `collectionPaths: [/lessons]` requires an object-compatible collection with stable direct keys. Contracts 1.0 does not implicitly turn list positions into scope identities. + +### D.21 Do not invent live parent-channel inheritance + +An embedded scope does not search parent or ancestor contract maps. Reuse exact Channel nodes by inline content or BlueId reference, and change bindings explicitly. A context-dependent parent binding requires a separately specified runtime type. + +--- + +*End of Blue Contracts and Processor Specification 1.0.* diff --git a/blue-contracts-core/src/test/java/blue/language/processor/BlueContractsTest.java b/blue-contracts-core/src/test/java/blue/language/processor/BlueContractsTest.java new file mode 100644 index 00000000..143e8a24 --- /dev/null +++ b/blue-contracts-core/src/test/java/blue/language/processor/BlueContractsTest.java @@ -0,0 +1,1073 @@ +package blue.language.processor;

Sections marked **informative** explain intent, examples, or implementation guidance. + +--- + +## 0. Overview + +Blue Language describes reality as a **content-addressed graph of typed nodes**. Text, integers, doubles, booleans, lists, and dictionaries are the basic building blocks. Larger nodes are formed by connecting those smaller nodes. + +An informative mental model is to treat a Blue node as a perfectly defined word. A human-readable `name` helps people discuss the word, while its **BlueId** identifies one exact immutable meaning. The same exact node has the same BlueId wherever it appears, and a BlueId may stand in place of the node's complete verified explanation. + +This analogy does not replace the formal rules below. In particular, a BlueId is a content address, not merely a chosen label: changing identity-bearing content changes the BlueId. + +Blue has one BlueId format and one BlueId algorithm. An exact node may be identified directly. An authored Source Document first passes through preprocessing, complete resolution, and canonicalization; the BlueId of the resulting Canonical Identity Input is the BlueId derived from that Source Document. `Content BlueId` is a permitted shorthand for this derivation, not a second identifier kind. + +A **Blue Graph** is the conceptual network of Blue nodes. Nodes are connected by ordinary object fields, list elements, type links, and `blueId` references. A **Blue Document** is one serialized root and whatever part of that graph is currently materialized with it. It is **not required to contain the whole graph**. + +A node may therefore appear in either of these equivalent forms: + +```yaml +x: + a: 1 + b: 1 +``` + +```yaml +x: + blueId: +``` + +When the materialized node verifies to the referenced BlueId, these forms identify the same graph edge and the same Blue node. Inline versus referenced representation is not a semantic distinction. + +This equivalence is a load-bearing invariant. A semantic Blue operation MUST be a function of node identity and logical content demanded by that operation. It MUST NOT be a function of whether a node was inline, collapsed, already expanded, cached, fetched from one blob, fetched from many chunks, or represented internally by one host object or many. + +The Blue Language defines four ordinary graph operations: + +| Operation | Meaning | +|---|---| +| **Expand** | Replace selected pure references with verified materialized content. | +| **Collapse** | Replace selected verified materialized nodes with pure references to their BlueIds. | +| **Resolve** | Apply type inheritance, overlays, merge rules, fixed values, and schema rules. | +| **Minimize** | Produce a smaller Source overlay that resolves to the same semantic result. | + +Expansion and collapse change representation only. Resolution and minimization change how explicit or type-derived content is expressed. These operations act on ordinary Blue nodes; they do not create a second graph model. + +Expansion and resolution are independent dimensions. A processor may expand and resolve only the paths needed for its next decision while leaving unrelated branches collapsed. Limits are supplied out-of-band to the Language operation and do not become Blue content, affect BlueId, or change semantic meaning. + +Blue also permits **specialization through typing and overlays**. Specialization is not a fifth graph operation. To specialize a node is to create a new, more specific node that uses another node as its `type` and adds compatible overlay content. The specialized node is a new node and normally has a new BlueId. By contrast, expanding a node only reveals more of the same existing node and preserves its BlueId. + +A useful test is: + +```text +same node, more of it visible -> expand +new node, more specific meaning -> specialize +``` + +Blue content commonly appears in the following forms: + +| Form | Purpose | Identity status | +|---|---|---| +| **Source Document** | Authored input. May use authoring sugar and the root `blue` directive. | Not necessarily direct BlueId Input. | +| **Preprocessed Document** | Source after preprocessing has applied authoring transforms and removed `blue`. | Eligible for resolution and, if otherwise valid, direct hashing. | +| **Expanded or collapsed form** | The same node with more or fewer referenced descendants materialized. | Expansion and collapse preserve BlueId. | +| **Resolved Form** | Type-merged and schema-validated semantic content. It may be complete or explicitly limited to demanded paths. | Carries semantic meaning; not necessarily direct BlueId Input. | +| **Minimized Overlay** | A reduced author-facing overlay that resolves to the same complete Resolved Form. | Derives the same BlueId through the full Source Document identity pipeline. | +| **Canonical Identity Input** | The one deterministic identity form derived from a complete Resolved Form. | Direct input to the BlueId algorithm; its BlueId is the Source Document's BlueId. | + +Canonicalization is separate from minimization. Canonicalization produces the one deterministic BlueId input. Minimization produces a convenient smaller Source overlay and is not necessarily unique. **Minimization is not a step in Source Document BlueId calculation.** + +The two paths from a complete Resolved Form are: + +```text +Source Document + -- preprocess --> Preprocessed Document + -- fully resolve --> complete Resolved Form + | \ + | canonicalize \ minimize + v v + Canonical Identity Input Minimized Overlay + | | + BlueId algorithm ordinary Source form + | | + v `-- if processed again, + BlueId follows the full pipeline + to the same BlueId +``` + +A Source Document, Resolved Form, or Minimized Overlay MUST NOT be directly hashed and assumed to produce the Source Document's BlueId. Only the Canonical Identity Input has that guarantee. + +Ordinary processors do not need to run this entire pipeline merely to inspect or update a document. They may expand and resolve only demanded fields, preserve unchanged children by BlueId, and collapse the result again. + +List identity is deliberately incremental. If `P` is the established BlueId of an exact list prefix and `X` is the established BlueId of one appended element, the BlueId of the longer list is calculated by one domain-separated fold step over `P` and `X`. The earlier elements do not need to be materialized or rehashed merely to append. Replacing, inserting, or removing an earlier element is different: the fold suffix from the first changed position must be recomputed. The exact algorithm and worked example are in §14.7. + +A Blue Document is a rooted slice of a larger graph: + +```text +Selected document slice ++-----------------------------+ +| root | +| +- local field | +| +- local list | +| +- type: { blueId: T } -----+----> external type node T ++-----------------------------+ + \--> more graph reachable by BlueId +``` + +This specification defines content-language semantics only. + +--- + +## 1. Scope, Goals, Versioning, and Conformance + +### 1.1 Goal + +Blue is a universal, deterministic **content language** with: + +- a strict, mergeable type system with overlay and subtyping rules; +- a content address called **BlueId** that is stable across equivalent content forms; +- a precise pipeline that maps an authored document to deterministic content identity; +- graph-slice semantics, so documents can contain local content and external `blueId` references; +- identity-preserving expansion and collapse; +- complete or demand-limited resolution; +- semantics-preserving minimization; +- explicit operation outcomes in which unavailable or unexpanded content is never confused with semantic absence; +- local verification of a directly materialized node whose complete children remain represented by their exact BlueIds. + +### 1.2 Out of scope + +The following are not defined by this specification: + +- runtime execution; +- event processing; +- channels; +- handlers; +- gas accounting; +- document update listeners; +- processor lifecycle markers; +- contract execution. + +The field `contracts` is reserved by the language because it is a possible field in Blue content and therefore can affect BlueId. Its runtime meaning is defined only by the separate Blue Contracts and Processor Specification 1.0. + +### 1.3 Versioning and specification selection + +This document defines **Blue Language 1.0**, the first public-version Language specification. + +A Blue node does **not** carry a required `languageVersion`, `specification`, or similar field. Adding such a field would make version selection part of content identity and would create a bootstrapping problem: an implementation would need to interpret identity-bearing content before knowing which identity rules apply. The processing environment therefore selects Blue Language 1.0 out-of-band and MUST declare that selection before parsing identity-bearing content. + +The exact BlueIds of referenced types remain the normal way in which content selects type semantics. Runtime execution languages are selected by their exact runtime-type BlueIds under the applicable runtime specification; ordinary documents do not require a Language-version field. + +Blue Language 1.0 publishes the canonical nodes and BlueIds for `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` exactly as contained in the release registry. Those nodes have already been reproduced by multiple implementations and their identity-bearing descriptions intentionally name Blue Language 1.0. Implementations MUST load and verify the registry nodes rather than reconstructing them from prose or source-code constants. + +After publication, an existing core-type BlueId MUST never acquire different semantics. A semantic change requires a new type node and BlueId. Editorial clarification that is not intended to alter identity-bearing meaning belongs outside the canonical node. + +Blue Language 1.0 is intended to remain stable. Editorial changes that do not alter normative meaning may be published as errata outside canonical registry nodes. Any change that alters the node model, BlueId algorithm, preprocessing, resolution, canonicalization, minimization, or the meaning of valid 1.0 content requires a new Language version and an out-of-band version-selection rule known before the node is interpreted. + +A valid unprefixed plain BlueId always denotes the BlueId v1 algorithm defined by this specification. A future incompatible BlueId version MUST use syntax that is not valid as a plain BlueId v1; it MUST NOT reinterpret an existing valid v1 string. + +### 1.4 Conformance + +A conforming Blue Language 1.0 implementation MUST implement all normative requirements in this specification. + +A conforming implementation MUST support: + +- parsing Blue Source Documents and BlueId Input; +- preprocessing, including the standard baseline preprocessing environment; +- type resolution and overlay merging; +- schema validation; +- list merge semantics and list control forms; +- provider-backed resolution when referenced content is required; +- complete and demand-limited resolution with explicit complete, absent, incomplete, and invalid outcomes; +- representation-transparent graph access through verified pure references; +- expansion semantics, including provider-backed materialization when referenced content is required; +- the semantics of expansion, collapse, resolution, and minimization; an implementation need not expose each as one public method, but all corresponding behavior it exposes MUST follow this specification; +- canonicalization for Source Document BlueId calculation; +- author-facing minimization behavior sufficient to pass the conformance fixtures; +- direct BlueId calculation and Source Document BlueId calculation; +- circular reference set BlueIds; +- rejection of invalid Blue Language 1.0 documents and invalid BlueId Input; +- the Blue Language 1.0 conformance suite. + +An implementation MAY expose detailed demand enums, node handles, provider batches, storage indexes, work diagnostics, or caches. Those are implementation surfaces. They MUST preserve the semantic results required here and MUST NOT become observable Blue content. + +A library or tool that implements only a subset of this specification may be useful, but it MUST NOT describe itself as a conforming Blue Language 1.0 implementation. + +### 1.5 Core registry and release artifacts + +The canonical Blue type registry is part of the Blue Language 1.0 release surface. Its entries for `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` are content-addressed and versioned with this specification. + +A conforming implementation MUST use the published registry BlueIds for core type aliases. A different registry binding does not produce portable Blue Language 1.0 Source Document BlueId results. `Content BlueId` remains permitted shorthand for those results. + +Canonical registry nodes are self-describing Blue content. A registry node's `name` and `description` fields are identity-bearing. A concise normative `description` SHOULD define the type's semantics. Changing that semantic description changes the type BlueId and defines a different type. + +Non-normative examples, rationale, translations, tutorial material, implementation notes, and editorial commentary MUST NOT be included in canonical registry nodes unless intentionally made identity-bearing. Such material belongs in this prose specification or in separate documentation. + +The registry file is the authority for the exact parsed string content of canonical nodes. Code blocks in this specification that claim to show canonical nodes SHOULD be generated from, or kept Blue-equivalent to, the registry entries used to calculate the published BlueIds. + +The core-registry manifest MUST publish, for every entry: + +- registry kind and specification version; +- stable entry key; +- path of the canonical node file; +- the calculated BlueId; +- the SHA-256 digest of the exact node file; +- `semanticDescriptionIdentityBearing: true`; +- the Language fixture-package identity that verifies it. + +The manifest itself MUST publish one content-addressed package identity calculated by the release rule declared in that manifest. The top-level release manifest MUST bind that core-registry package identity. + +A complete Blue Language 1.0 conformance release consists of: + +1. this prose specification; +2. the canonical Blue 1.0 core-type registry and published BlueIds; +3. the machine-readable Blue Language 1.0 fixture package and its identity; +4. a content-addressed release manifest that binds the preceding artifacts. + +The release manifest MUST identify at least the specification revision, core-registry identity, fixture-package identity, and artifact digests. If the prose, registry, fixtures, or manifest conflict, the release is inconsistent and MUST be corrected. Implementations MUST NOT guess which artifact wins. + +Until all four artifacts exist and independent fixture execution has succeeded, this package remains an implementation baseline rather than a final public conformance release. + +--- + +## 2. Serialization and Data Model + +### 2.1 JSON data model (normative) + +Blue documents use the JSON data model: + +- objects; +- arrays; +- strings; +- numbers; +- booleans; +- null. + +YAML is an authoring syntax for this JSON data model. A YAML parser used for Blue MUST NOT introduce YAML-specific data types into the Blue data model. + +### 2.2 YAML restrictions (normative) + +When YAML is used for Blue serialization: + +- duplicate object keys MUST be rejected; +- custom YAML tags MUST be rejected; +- Portable Blue YAML MUST reject YAML anchors, aliases, and merge keys. An implementation MAY expose a non-portable preprocessing mode that expands them deterministically before Blue parsing, but documents relying on that mode are not portable Blue Source Documents. +- non-JSON implicit types, including timestamps, binary blobs, sets, and ordered maps, MUST be disabled; +- timestamp-like values SHOULD be quoted by authors. Blue Language 1.0 defines no timestamp scalar. + +Blue Language 1.0 YAML uses the YAML 1.2 JSON schema data model. Portable Blue YAML MUST reject custom tags, non-string object keys, binary tags, sets, ordered maps, and non-JSON implicit scalar types. + +The parsed value of a YAML block scalar is the exact Text value. Blue performs no block-scalar normalization. Different YAML scalar styles, indentation, folding, chomping indicators, trailing newlines, or line endings that produce different parsed strings produce different BlueIds. + +Examples: + +```yaml +# Text, not a Date/Time type in Blue Language 1.0 +ts: "2025-09-01T12:00:00Z" +``` + +Blue Language 1.0 does not define a core Date or Timestamp scalar type. + +### 2.3 Duplicate keys (normative) + +Serialized Blue documents MUST NOT contain duplicate object keys. Parsers MUST reject duplicate keys. Later-key-wins behavior is not conforming. + +### 2.4 Number tokens and large integers (normative) + +Blue distinguishes the mathematical value of an integer from the JSON/YAML encoding used to carry it. + +The interoperable **safe JSON numeric integer range** for Blue Language 1.0 is: + +```text +[-9007199254740991, 9007199254740991] +``` + +JSON itself does not define a numeric range. Blue uses this safe range because it is exactly representable by JSON implementations that store numbers as IEEE 754 binary64 values. + +Rules: + +1. An unquoted integer token within this range MAY be used as an `Integer` value. +2. An integer value outside this range MUST be authored as a quoted canonical decimal string and MUST have explicit type `Integer` or a type that resolves to `Integer`. +3. In Canonical Identity Input and BlueId Input, an `Integer` value outside this range MUST be represented as its quoted canonical decimal string while retaining the explicit `Integer` type. +4. The canonical decimal string form is an optional leading `-` followed by decimal digits, with no leading zeros except the single digit `0`. +5. Quoted decimal text without an explicit `Integer` type is Text, not Integer. + +A quoted canonical decimal string value is interpreted as an `Integer` when the node has an explicit effective type that resolves to `Integer`. The effective type may be authored locally or inherited from the resolved type chain. + +If no effective type resolves to `Integer`, quoted decimal text is Text. + +If an effective type resolves to `Integer` and the quoted value is not a valid canonical decimal integer string, resolution MUST fail. + +Primitive scalar inference for quoted strings is provisional for Source Documents. Resolution MUST refine a quoted scalar's effective scalar type to `Integer` when the inherited or explicit effective type resolves to `Integer` and the quoted value is a valid canonical decimal integer string. It MUST fail when that effective type requires `Integer` and the quoted value is not canonical Integer text. + +Examples: + +```yaml +small: + type: Integer + value: 42 + +large: + type: Integer + value: "9007199254740992" +``` + +The same rule applies below the negative bound: + +```yaml +veryNegative: + type: Integer + value: "-9007199254740992" +``` + +Example with inherited Integer type: + +```yaml +# Type +name: Account +accountId: + type: Integer + +# Source instance +type: Account +accountId: "9007199254740992" +``` + +After preprocessing and resolution, `accountId` is an Integer value because the effective inherited type resolves to `Integer`. + +Without the inherited or explicit Integer type, the same quoted value is Text. + +Floating-point `Double` values MUST be finite. `NaN`, `Infinity`, and `-Infinity` are not valid Blue scalar values. + +Double parsing MUST produce a finite IEEE 754 binary64 value using round-to-nearest, ties-to-even semantics. A numeric token that overflows to positive or negative Infinity, underflows to a non-finite value, or parses as NaN is invalid. + +A parsed `-0.0` Double value compares equal to `0.0` and canonicalizes as JSON number `0` under RFC 8785. The node remains Double because its effective type is Double. + +A Double whose RFC 8785 canonical JSON representation is integer-looking, such as `1`, remains Double because its effective type is represented in BlueId Input. + +If a parser cannot deterministically parse a numeric token as binary64 with these semantics, the implementation MUST reject the token or require explicit authoring in a supported form. + +### 2.5 Numeric token inference (normative) + +When a numeric Source Document value has no explicit type: + +- an unquoted integer token with no decimal point and no exponent infers `Integer`; +- an unquoted numeric token with a decimal point or exponent infers `Double`, even if its mathematical value is integral. + +Examples: + +```yaml +a: 1 # Integer +b: 1.0 # Double, canonical numeric payload may render as 1 +c: -0.0 # Double, canonical numeric payload renders as 0 +d: 1e999 # invalid Double +``` + +If a parser cannot preserve the lexical distinction between integer tokens and decimal/exponent tokens, it MUST require explicit type annotations for ambiguous numeric values or document that such inputs are not portable Source Documents. + +### 2.6 String and multiline scalar identity (normative) + +After parsing, a Blue string value is identity-bearing exactly as parsed. Blue Language performs no automatic whitespace normalization, line-ending normalization, trailing newline stripping, indentation rewriting, Unicode normalization, case folding, or YAML block-scalar canonicalization. + +Different YAML scalar styles may produce different string values and therefore different BlueIds. In particular, YAML block scalar choices such as `|`, `|-`, `|+`, `>`, and `>-` may differ in line folding and trailing newline behavior. + +Canonical registry nodes SHOULD be generated, fixture-checked, or otherwise protected against accidental string drift. Authors of identity-sensitive documents SHOULD treat edits to multiline `description` fields as content edits, not formatting edits. + +Blue Language uses the parsed Unicode code-point sequence. Implementations MUST NOT normalize Text by default. Applications that need a normalization convention, such as NFC, SHOULD apply it explicitly at the application/preprocessing layer. + +--- + +## 3. Blue Graph, Blue Documents, and References + +### 3.1 The Blue Graph (normative) + +The **Blue Graph** is the conceptual content-addressed network of Blue nodes. Edges in the graph arise from: + +- ordinary object fields, for example `address -> child node`; +- list elements; +- type links, for example `type: ...`; +- `blueId` references. + +Nodes are identified by BlueId. The graph is global and content-addressed; it is not owned by any single document. + +### 3.2 Blue Documents as graph slices (normative) + +A **Blue Document** is a serialized rooted slice of the Blue Graph. It may contain: + +- fully materialized child nodes; +- pure references to external nodes using `{ blueId: ... }`; +- a mixture of local content and external references. + +A Blue Document is not required to be closed. A `{ blueId: X }` reference may point to content outside the selected document. Implementations use a provider only when an operation demands referenced content. + +A materialized child whose BlueId is `X` and a pure `{ blueId: X }` reference are representation-equivalent. Language operations, validators, and higher-level processors MUST NOT assign different semantic meaning merely because one form is expanded and the other is collapsed. + +This equivalence also permits one exact configuration node to be reused in many larger documents. For example, a runtime Channel or participant-binding node may be written inline in one document and as `{ blueId: X }` in another. Blue Language treats both as the same exact node. Whether a runtime gives that node executable meaning is outside this specification; Blue Language itself does not create live aliases to unrelated parent or ancestor fields. + +### 3.3 Pure references (normative) + +A **pure reference** is exactly: + +```yaml +blueId: +``` + +or, as a field value: + +```yaml +field: + blueId: +``` + +A pure reference object MUST NOT carry sibling fields. The following is not a pure reference: + +```yaml +blueId: +name: Something +foo: bar +``` + +Mixed `blueId` forms MUST be rejected in Source Documents, Preprocessed Documents, Canonical Identity Input, and BlueId Input. Provider metadata MUST be represented out-of-band or in a non-Blue envelope. + +A non-Blue envelope is packaging metadata outside the Blue Document root. It is not part of the Blue node and is not included in BlueId calculation. + +A pure reference cannot carry sibling fields. To specialize referenced content, the reference MUST appear in a type position or be resolved as an ancestor/type, and the overlay MUST be written as ordinary instance content outside the pure reference object. + +Invalid: + +```yaml +blueId: X +extra: value +``` + +Valid as a typed overlay: + +```yaml +type: + blueId: X +extra: value +``` + +### 3.4 Document identity (normative) + +The BlueId of a Blue Document is the BlueId of its root node. There is no separate document-level identity above the root node. + +A Blue Document root MAY be a scalar, list, object, or pure reference. Scalar and list roots follow the same wrapper-equivalence rules as field values. A Blue Document root MUST NOT be `null`. + +--- + +### 3.5 Exact-node equivalence and materialization state (normative) + +Let `X` be a valid BlueId. A pure reference: + +```yaml +blueId: X +``` + +and any verified materialization whose BlueId is `X` denote the same exact Blue node. + +For semantic Blue operations, materialization state is out-of-band. It MUST NOT change: + +- node kind; +- field or list membership; +- equality or matching; +- effective type or schema; +- presence or absence; +- any semantic conclusion once the same logically required evidence is available; +- BlueId. + +A serialization-inspection API MAY expose that a supplied syntax object contains the key `blueId`. A semantic graph API MUST NOT expose the pure-reference wrapper as an ordinary child field of the referenced node. For example, if `/x` denotes node `X`, a semantic lookup of `/x/blueId` does not succeed merely because `/x` was supplied in collapsed form. Exact identity is obtained through an explicit node-identity operation. + +Expansion state, provider location, cache state, and storage segmentation are not Blue content and MUST NOT be inserted into a Blue node. + +### 3.6 Identity-preserving implementation values (normative behavior) + +An implementation MAY represent an exact node internally by a handle containing its BlueId, optional verified materialization, and out-of-band provider or coverage information. No particular handle class or public API is required. + +Whenever an implementation passes, snapshots, emits, stores, or returns an already verified node, it MUST preserve the exact BlueId and MUST NOT require recursive cloning or transitive materialization merely to carry that value. + +Portable application semantics MUST NOT depend on whether such an implementation value currently carries materialized content. When an operation demands unavailable content, the operation returns an incomplete or provider outcome under §§10 and 12 rather than inventing semantic absence. + +## 4. Node Model and Reserved Fields + +### 4.1 Node anatomy (normative) + +A **Blue node** consists of reserved language fields and, optionally, one primary payload kind. + +```text +Node = reserved language fields + zero or one payload kind +``` + +The permitted payload kinds are: + +- **scalar payload**: a `value` field carrying a string, number, or boolean; +- **list payload**: an `items` field carrying an ordered sequence; +- **object payload**: one or more ordinary child fields, where ordinary child fields are fields whose keys are not reserved language keys. + +A node MUST NOT combine payload kinds. For example, a node MUST NOT contain both `value` and `items`, or both `value` and ordinary child fields. + +A node MAY have no payload. Such a node is a metadata-only, type-only, schema-only, or overlay-only node. Examples include: + +```yaml +age: + type: Integer +``` + +and: + +```yaml +name: Person +``` + +A pure reference is a special metadata-only reference node. It is valid only when the object contains exactly `blueId`. + +If a node has no payload and no retained reserved content after object-field cleaning, it may normalize to an empty map and be omitted when it appears as an object field. It MUST NOT be silently deleted when it appears as a list element; list element normalization is context-sensitive (§11.5, §14.2). + +### 4.1.1 Unconstrained field declarations (normative) + +A declaration-only child with no effective `type`, fixed payload, payload-kind constraint, or applicable schema constraint does not constrain the kind or type of a later value at that path. + +For example: + +```yaml +request: + description: > + Optional application-defined request payload. +``` + +means that `request`, when present, may contain any valid Blue node: a scalar, list, object, specialized node, or pure reference. It remains optional unless its effective schema contains `required: true`. + +A required but otherwise unconstrained field is written as: + +```yaml +request: + description: > + Required application-defined request payload. + schema: + required: true +``` + +Omitting `type` is the ordinary way to express "no type constraint." By contrast: + +```yaml +request: + type: Dictionary +``` + +constrains the field to the canonical Dictionary type or a compatible specialization. It does **not** mean "any Blue value." Likewise, `type: List` constrains the value to a List even when `itemType` is omitted. + +A meaningful `name` or `description` may retain and document an unconstrained declaration. An empty declaration `{}` may be removed by object-field cleaning and therefore is not a reliable declaration marker. + +### 4.2 Reserved language keys (normative) + +The following keys are reserved by the language: + +```text +name, description, +type, itemType, keyType, valueType, +value, items, +blueId, blue, +schema, mergePolicy, +contracts +``` + +The following keys are reserved-invalid and MUST be rejected wherever they would appear as object fields: + +```text +properties, constraints +``` + +Reserved fields are grouped as follows: + +| Category | Fields | +|---|---| +| Identity labels | `name`, `description` | +| Type and constraint metadata | `type`, `itemType`, `keyType`, `valueType`, `schema`, `mergePolicy` | +| Payload wrappers | `value`, `items` | +| Reference and preprocessing controls | `blueId`, `blue` | +| Reserved extension field | `contracts` | + +`contracts` is reserved by the language but semantically defined only by the Blue Contracts and Processor Specification 1.0. + +The key `blue` is valid only as a preprocessing directive on the root of a Source Document. A conforming implementation MUST reject `blue` anywhere else. Direct BlueId calculation MUST reject any node containing `blue` as direct BlueId Input. + +There is no `properties` field in the Blue Language. The key `properties` is reserved-invalid in Blue Language 1.0 and MUST NOT appear as an ordinary child field or language wrapper. Applications that need a data key literally named `properties` MUST use an escaped representation defined by the application's type. + +Reserved language keys cannot be used as ordinary child-field names in direct object encoding. Direct object encoding can therefore represent only data keys that do not collide with reserved language keys. +Applications that need arbitrary user keys, including keys that equal reserved language keys, MUST use an escaped representation defined by the application's type. + +### 4.3 Reserved field value types (normative) + +Implementations MUST validate reserved field value types. + +| Field | Required value shape | +|---|---| +| `name` | string, or absent | +| `description` | string, or absent | +| `type` | node, string alias in Source Documents before preprocessing, or pure reference | +| `itemType` | node, string alias in Source Documents before preprocessing, or pure reference | +| `keyType` | node, string alias in Source Documents before preprocessing, or pure reference | +| `valueType` | node, string alias in Source Documents before preprocessing, or pure reference | +| `value` | string, number, boolean, or absent | +| `items` | list, or absent | +| `blueId` | string BlueId, only in pure references | +| `blue` | root Source Document only; string directive alias, inline preprocessing-directive node, or pure reference to one | +| `schema` | object using only schema keywords from §9, pure reference to such an object, or absent | +| `mergePolicy` | `append-only`, `positional`, or absent | +| `contracts` | object, pure reference to such an object, or absent; runtime semantics out of scope | + +Wrong reserved-field types MUST be rejected. Implementations MUST NOT silently coerce reserved field values such as `blueId: 123` or `name: true` into strings. A pure reference accepted for `schema` or `contracts` MUST be expanded when the operation needs to validate or interpret the referenced object's contents; its collapsed form is not an exemption from the field's semantic shape rules. + +### 4.4 `contracts` boundary (normative) + +In Blue Language 1.0, `contracts` is a reserved identity-bearing content field. A language implementation MUST parse, preserve, resolve, canonicalize, and hash `contracts` as content. It MUST NOT execute `contracts`. + +Unless a separate processor specification is explicitly being applied, `contracts` participates in language-level merge and canonicalization according to ordinary object-field rules. Runtime interpretation, reserved processor keys under `contracts`, processor lifecycle behavior, and contract capability handling are outside this specification. + +When a `contracts` value is a pure reference and an operation needs to merge or inspect that map, the reference MUST be expanded and verified first. Language-level merge of the resulting `contracts` maps is field-wise: + +- If only the ancestor contributes a contract entry at key `k`, the entry is materialized in the Resolved Form as type-derived content. +- If only the instance contributes a contract entry at key `k`, the entry is preserved as instance-supplied content. +- If both ancestor and instance contribute `contracts[k]`, the two contract nodes are merged recursively under the same fixed-value, type-compatibility, schema, and object-field rules used for ordinary child fields. +- A descendant MUST NOT remove an inherited contract entry during language resolution. Runtime removal or mutation of contracts, if allowed, belongs to the Blue Contracts and Processor Specification 1.0. +- The language resolver MUST NOT interpret, execute, sort, dispatch, or validate processor-specific contract behavior. + +Processor-reserved keys inside `contracts` have no runtime effect in this specification. They are still parsed, resolved, canonicalized, and hashed as content. + +### 4.5 `name` and `description`: identity vs field semantics (normative) + +`name` and `description` are content on the node. They affect BlueId. + +They are also matcher-neutral. Matchers MUST ignore `name` and `description` for: + +- type conformance checks; +- subtype compatibility checks; +- structural or shape matching; +- resolution matching. + +Identity equality includes `name` and `description`. Structural and type equality ignore them. + +### 4.6 Document identity vs field semantics for labels (normative) + +A node whose `type` is `T` is not `T`; it is a new entity. The resolved node's top-level `name` and `description` come only from the instance and MUST NOT be inherited from the type. The embedded type object may carry its own `name` and `description` inside `node.type`. + +When a type materializes declaration-only fields or list elements into an instance, those child nodes carry the type's `name` and `description` as inherited labels until the instance explicitly overrides them. + +However, when the inherited child node contains a fixed payload value, fixed list payload, fixed object subtree, or pure reference, the labels on that node are part of the inherited fixed value's identity. A descendant MUST NOT change `name` or `description` on such a fixed-value node unless the inherited type leaves that label absent or the change is otherwise allowed by an explicit resolution rule. + +Dereferencing `{ blueId: X }` to materialize a node may copy the referenced node's `name` and `description` onto that materialized node, because the node itself is being materialized. This is expansion, not type inheritance. + +--- + +## 5. Authoring Forms and Wrapper Equivalence + +### 5.1 Wrapper equivalence (normative) + +To improve ergonomics, Blue admits equivalent authoring forms for scalars and lists, provided the wrapper has no other keys. + +Scalar sugar: + +```yaml +x: 1 +``` + +is equivalent to the wrapped form: + +```yaml +x: + value: 1 +``` + +List sugar: + +```yaml +x: [a, b] +``` + +is equivalent to: + +```yaml +x: + items: [a, b] +``` + +### 5.2 Sugar vs explicit metadata (normative) + +The sugar rule applies only when the wrapper has no other keys. Therefore: + +```yaml +x: 1 +``` + +is sugar for: + +```yaml +x: + value: 1 +``` + +but: + +```yaml +x: + type: Integer + value: 1 +``` + +is not sugar. It is the explicit scalar node form with metadata. + +A node may carry metadata such as `type`, `description`, `schema`, or `mergePolicy` alongside a payload kind. Metadata is not a payload kind. + +### 5.3 Object nodes (normative) + +Object payloads are written directly as ordinary child fields: + +```yaml +x: + a: 1 + b: 2 +``` + +There is no `properties` wrapper. The key `properties` is reserved-invalid (§4.2). + +### 5.4 Identity over forms (normative) + +Equivalent authoring forms of the same semantic content MUST derive the same BlueId through the Source Document identity pipeline. + +The BlueId algorithm operates on the abstract node model after canonical input normalization, not on authoring syntax. In particular, a bare scalar and its `{ value: ... }` wrapped form normalize identically. A bare list and its `{ items: ... }` wrapped form normalize identically. + +--- + +## 6. Preprocessing and the `blue` Directive + +### 6.1 Purpose and governing model (normative) + +Every Blue Source Document is processed by the standard preprocessing algorithm defined by this specification. The absence of a root `blue` directive means that the document supplies no document-specific preprocessing configuration; it does **not** disable standard preprocessing. + +The standard preprocessing algorithm is part of Blue Language 1.0. It is not represented by an implicit, injected, or hidden `blue` directive. + +The root of a Source Document MAY contain a `blue` field. The optional `blue` directive supplements standard preprocessing with: + +- document-local type aliases declared through `imports`; and +- an ordered list of explicitly identified source transformations declared through `transformations`. + +The `blue` directive cannot replace, reorder, or disable mandatory baseline preprocessing. + +Preprocessing is part of Source Document BlueId calculation. It is not part of direct BlueId calculation, because direct BlueId accepts only BlueId Input. + +The portable value of `blue` is either: + +1. an inline preprocessing-directive node; or +2. a pure reference to an exact preprocessing-directive node: + +```yaml +blue: + blueId: +``` + +An inline directive and a verified materialization of a referenced directive are equivalent. The directive may therefore be expanded or collapsed like any other exact Blue node. Expansion or collapse of the directive MUST NOT change the preprocessed result. + +A pure reference under `blue` MUST remain a pure reference. It cannot carry sibling fields. To combine or change a referenced directive, an author creates another exact directive node containing the desired combined imports and transformations, and may then reference that new node by BlueId. + +A string-valued `blue` MAY be supported as authoring shorthand for an implementation-configured directive alias: + +```yaml +blue: Ticket Details v1.51 +``` + +The alias MUST resolve to one exact preprocessing-directive BlueId before preprocessing begins. An unbound alias fails deterministically. A Source Document that depends on a string alias has a portable Source-derived BlueId only when the exact alias-to-BlueId binding is itself identity-bound by the declared preprocessing environment or release artifact. The portable self-contained form is the pure reference form. + +Raw URL fetching is not a portable meaning of a string-valued `blue`. A URL MAY be used by a provider as a transport location for an expected BlueId, but unverified URL content MUST NOT define preprocessing semantics. + +### 6.2 Portable preprocessing-directive node (normative) + +A portable materialized preprocessing-directive node MAY contain the following directive fields: + +```text +imports +transformations +``` + +It MAY also contain ordinary identity-bearing node metadata such as `name`, `description`, and an exact `type` reference. Such metadata identifies the directive node itself but does not become content of the preprocessed Source Document. + +The `imports` field, when present, MUST be either: + +- an object mapping aliases to pure references; or +- a pure reference to such an object. + +The `transformations` field, when present, MUST be either: + +- a list of transformation nodes; or +- a pure reference to such a list. + +Each transformation list item MAY be materialized inline or represented by a pure reference. Every referenced directive, imports object, transformations list, or transformation node required by preprocessing MUST be fetched through the configured provider and verified against its requested BlueId before use. + +A preprocessing-directive node MUST NOT itself contain a `blue` directive. Blue Language 1.0 does not define recursive directive composition or a separate `profile` field. Reuse is achieved by placing the complete directive in an exact node and using: + +```yaml +blue: + blueId: +``` + +Unknown directive fields are not portable. A conforming strict implementation MUST reject an unknown directive field unless an exact separately published preprocessing extension defines that field, its ordering, its identity, and its conformance behavior. + +### 6.3 Imports (normative) + +A conforming implementation MUST support this portable shape: + +```yaml +blue: + imports: + AliasName: + blueId: +``` + +Each key under `imports` is an authoring alias. Each value MUST be a pure reference to a plain BlueId. Cyclic-member identities and algorithm-internal placeholders are not valid import targets in Blue Language 1.0. + +The effective import map consists of: + +1. the canonical built-in core aliases supplied by the Blue Language 1.0 core registry; and +2. the aliases declared by the effective preprocessing directive. + +An alias name MUST NOT be declared more than once in the effective imports object. A directive import MUST NOT redefine a built-in core alias unless it maps to the same canonical BlueId. + +Imports are scoped to the Source Document being preprocessed. Automatic alias substitution applies only in these type-bearing positions: + +```text +type +itemType +keyType +valueType +``` + +The same Text value in an ordinary data field is not replaced merely because it equals an alias name. + +The effective import map is established and verified before transformation execution, but automatic alias substitution is performed only during mandatory baseline preprocessing **after all declared transformations have completed**. This permits a transformation to emit a type alias that is then resolved by the document's imports. + +An imported alias that is not used does not affect the resulting Preprocessed Document or its Source-derived BlueId. + +### 6.4 Transformations (normative) + +The portable transformation list has this shape: + +```yaml +blue: + transformations: + - type: + blueId: + # transformation-specific configuration +``` + +A transformation node MUST have an exact effective transformation type that can be established without applying the Source Document's aliases or transformations. In the portable form, the transformation's `type` is a pure BlueId reference, or the transformation item is itself a pure reference to a verified node whose transformation type can be established from exact content. + +The exact transformation type BlueId selects the deterministic transformation implementation. Human-readable `name` values do not select transformation semantics. + +A required transformation whose type is unsupported MUST cause deterministic preprocessing failure. An implementation MUST NOT ignore, approximate, reorder, or substitute a required transformation. + +Declared transformations execute under these rules: + +1. the list order is semantic; +2. each transformation is applied exactly once; +3. transformation `i + 1` receives the complete output of transformation `i`; +4. the first transformation receives the parsed Source Document with the root `blue` field removed; +5. transformations run before mandatory baseline preprocessing; +6. automatic import substitution and primitive inference have not yet been applied when a transformation begins; +7. a transformation MAY consult the already established effective import map when its exact transformation specification defines such access, but this does not itself perform alias substitution; +8. a transformation MUST NOT introduce a `blue` field at any path; +9. a transformation's output may use ordinary Source syntax, wrapper sugar, imported aliases, bare primitive values, and list placeholders; mandatory baseline preprocessing normalizes that output afterward. + +The transformation list is not repeatedly evaluated and is not applied until reaching a fixed point. + +A portable transformation type MUST define, through its exact published semantics and fixtures: + +- accepted input and configuration shape; +- exact deterministic output rules; +- collision and duplicate-key behavior; +- Unicode, locale, date/time, and numeric behavior where applicable; +- error behavior; +- resource limits or a deterministic bound; +- whether and how the effective import map is available; +- conformance fixtures. + +Transformations MUST be pure and deterministic. They MUST NOT depend on ambient time, randomness, locale, time zone, environment variables, local files, unverified network content, mutable databases, cache state, thread scheduling, or any other hidden state. + +### 6.5 Exact preprocessing order (normative) + +A conforming implementation MUST produce the result defined by the following conceptual algorithm. Implementations MAY fuse or optimize stages only when the observable result and deterministic failures remain identical. + +#### Stage 1 — Parse the Source Document + +Parse JSON or portable YAML under §§2.1–2.3. Preserve the root `blue` value for directive processing. Reject duplicate keys and invalid Blue source syntax. + +#### Stage 2 — Establish the effective directive without mutating the Source Document + +1. If `blue` is absent, use an empty document-specific directive. +2. If `blue` is a string, resolve it through the declared directive-alias binding to one exact BlueId. +3. If `blue` is a pure reference, fetch and verify the referenced preprocessing-directive node. +4. If `blue` is inline, validate it as a preprocessing-directive node. +5. Materialize and verify any referenced `imports`, `transformations`, and transformation items required by the directive. +6. Build and validate the effective import map. +7. Resolve every transformation to a supported exact transformation implementation. +8. Freeze the ordered transformation list. + +If this stage cannot complete, preprocessing fails before any transformation executes. + +#### Stage 3 — Remove `blue` + +Create the working Source Document by removing the root `blue` field. The directive is not passed as ordinary document content to transformations. + +#### Stage 4 — Execute declared transformations + +Apply the frozen transformations exactly once each, in declared list order. Each transformation consumes the prior working result and produces the next working Source Document. + +If any transformation fails, produces invalid Source structure, introduces `blue`, exceeds its deterministic limit, or requires unavailable/invalid evidence, preprocessing fails. No partially transformed document is a successful result. + +#### Stage 5 — Apply mandatory baseline preprocessing + +Apply the following baseline operations to the transformed Source Document in this order: + +1. **Wrapper normalization.** Normalize scalar and list authoring sugar into the abstract Blue node model (§5). +2. **List placeholder normalization.** Normalize Source list elements that are `null`, `{}`, or recursively clean to an empty object into `$empty: true` (§11.5). +3. **Type-alias substitution.** Replace built-in and document-import aliases in `type`, `itemType`, `keyType`, and `valueType` positions with their canonical pure references. +4. **Primitive scalar inference.** Assign `Text`, `Integer`, `Double`, or `Boolean` to untyped primitive scalar payloads under §§2.4–2.5 and §14.3. +5. **Preprocessed-form validation.** Reject unresolved authoring aliases in type-bearing positions, nested or transformation-introduced `blue`, invalid payload combinations, malformed list controls, and any other invalid Preprocessed Document content. + +This ordering is normative. In particular: + +- transformations see the source before automatic import substitution and primitive inference; +- a transformation may emit `type: Person`, after which the `Person` import is substituted in Stage 5; +- a transformation may emit `count: 7`, after which Integer inference occurs in Stage 5; +- a transformation that replaces an alias with an exact pure reference prevents later import substitution at that position because no alias remains there. + +Applying preprocessing to an already valid Preprocessed Document that contains no `blue`, no unresolved aliases, and no Source-only placeholder forms MUST be idempotent. + +### 6.6 Identity and provenance (normative/informative) + +The `blue` directive is preprocessing configuration, not semantic content of the resulting document. Successful preprocessing removes it completely. + +Therefore: + +- an inline directive and the same directive supplied as `{ blueId: X }` produce the same result; +- different directive nodes may produce the same Preprocessed Document and Source-derived BlueId; +- different alias names that resolve to the same exact type may produce the same Source-derived BlueId; +- unused imports do not affect the Source-derived BlueId; +- source language, field spelling before a rename transformation, and preprocessing configuration are not recoverable from the Source-derived BlueId alone. + +Systems that require authoring provenance SHOULD retain an out-of-band preprocessing receipt containing, as applicable: + +```text +source artifact identity +Blue Language release identity +directive BlueId or alias binding identity +ordered transformation node identities +effective imports identity +preprocessed result BlueId +final Source-derived BlueId +diagnostics +``` + +The receipt is not part of the resulting Blue document unless an application explicitly stores it as content. + +### 6.7 Security and acquisition (normative) + +Remote acquisition of directive and transformation nodes is disabled by default unless the host explicitly configures a provider capable of obtaining exact BlueIds. + +Any directive, imports object, transformations list, transformation node, or transformation dependency fetched by BlueId MUST verify against that BlueId before use. Verification failure causes deterministic preprocessing failure. + +An implementation-local directive alias MUST resolve to one exact BlueId. It MUST NOT resolve directly to mutable or unverified content. + +A provider MAY use HTTP, a database, a filesystem, or another transport internally, but transport location is not preprocessing meaning. The requested BlueId and verified returned content define the acquired node. + +Implementations MUST impose deterministic hosted bounds on preprocessing, including suitable limits for transformation count, directive graph depth, referenced preprocessing resources, input/output node count, and text processed. Exceeding a bound causes preprocessing failure and MUST NOT return a partial successful document. + +### 6.8 General preprocessing rules (normative) + +- The `blue` directive is valid only on the root of a Source Document. +- A nested `blue` field is invalid. +- The `blue` directive is not semantic content of the resulting document. +- A document containing `blue` is not valid direct BlueId Input. +- Preprocessing MUST remove `blue` before resolution, canonicalization, or Source Document BlueId hashing. +- Direct BlueId calculation MUST reject a node containing `blue`. +- Simply ignoring `blue` is not conforming. +- Unsupported required transformations fail deterministically. +- Missing directive or transformation evidence is not treated as an empty directive. + +--- + +## 7. BlueId: One Identifier, Two Calculation Paths + +### 7.1 One BlueId (normative) + +Blue defines one identifier format and one identity algorithm: **BlueId**. + +Every valid exact Blue node has one BlueId. That BlueId identifies the node's exact immutable content. A pure reference: + +```yaml +blueId: X +``` + +always denotes the exact Blue node whose BlueId is `X`. It does not denote an authoring alias, a family of equivalent Source Documents, or an implementation-selected representation. + +A human-readable `name` may help people discuss a node, but only the BlueId identifies its exact content. Expansion and collapse preserve BlueId because they reveal or hide verified materialization of the same node. + +Blue does **not** define separate `NodeBlueId`, `SemanticBlueId`, or `MeaningId` identifier kinds. The phrases **direct BlueId calculation** and **Source Document BlueId calculation** describe two ways to derive an ordinary BlueId; they do not define different result formats or namespaces. + +This section defines the relationship conceptually. The exact BlueId v1 algorithm is specified in §14. + +### 7.2 Two calculation paths (normative) + +#### Direct BlueId calculation + +Direct calculation applies the BlueId algorithm to valid **BlueId Input**: + +```text +valid exact Blue node + -> BlueId input normalization + -> BlueId algorithm + -> BlueId +``` + +This is the normal identity path for exact graph nodes, provider verification, pure references, document revisions, type definitions, workflow bodies, event nodes, list prefixes, and every immutable fragment. + +#### Source Document BlueId calculation + +A Source Document may contain authoring sugar, a root `blue` directive, type aliases, overlays, or list controls. Its identity is therefore derived through the complete Source pipeline: + +```text +Source Document + -> preprocess + -> complete resolution + -> canonicalization + -> Canonical Identity Input + -> direct BlueId calculation + -> BlueId +``` + +The resulting value is an ordinary BlueId: the BlueId of the unique Canonical Identity Input. This specification also uses **Source-derived BlueId** as descriptive prose for that result; it does not name a different identifier type. + +The term **Content BlueId** MAY be used as shorthand for "the BlueId derived from this Source Document through the complete identity pipeline." It describes the relationship between a Source Document and a BlueId. It is not a second kind of BlueId. + +All conforming implementations MUST derive the same BlueId for equivalent Source Documents under the same Blue Language release and canonical registry bindings, provided every demanded reference resolves to the same verified node. Provider location, cache contents, lookup order, batching, and other ambient provider state are not identity inputs. + +### 7.2.1 What the Source-derived BlueId identifies (normative) + +The Source-derived BlueId identifies the exact Canonical Identity Input, not the original authoring syntax. + +For example, these Source Documents may derive the same BlueId: + +```yaml +blue: + imports: + Person: + blueId: + +type: Person +name: Alice +``` + +```yaml +type: + blueId: +name: Alice +``` + +Their aliases and preprocessing configuration differ, but their Canonical Identity Input is the same exact node. + +Consequently, a pure reference containing that BlueId refers to the canonical exact node. It does not preserve which alias, transformation spelling, YAML formatting, or Minimized Overlay was originally authored. A system that must preserve authoring provenance SHOULD retain a separate source artifact hash or preprocessing receipt. + +A Source Document provider MAY return authored Source content only under the explicit provider mode defined in §12.3. That mode verifies the Source-derived BlueId by running the complete pipeline. It does not change the meaning of `{ blueId: X }`, which still identifies one exact node `X`. + +### 7.2.2 Intermediate forms and direct hashing (normative) + +The following forms may all participate in expressing the same content: + +```text +Source Document +Preprocessed Document +Resolved Form +Minimized Overlay +Canonical Identity Input +``` + +They are not interchangeable as direct BlueId inputs. + +- A Source Document may contain `blue`, aliases, or Source-only controls and therefore may not be valid BlueId Input. +- A Resolved Form may contain inherited materialized content that canonicalization will omit as derivable. +- A Minimized Overlay is Source form and may contain `$previous`, `$pos`, `$replace`, or optional collapse choices. +- A Canonical Identity Input is the unique exact node whose direct BlueId is the Source Document's BlueId. + +A conforming implementation MUST NOT directly hash a Source Document, Resolved Form, or Minimized Overlay and describe that result as the Source Document's BlueId unless the form has first been proven identical to the Canonical Identity Input. + +### 7.3 Identity preservation across forms (normative) + +Expansion preserves BlueId when the provider returns verified content. Pure references contribute their target BlueIds; materializing a reference does not change the surrounding node's BlueId when the materialized content verifies to that identity. + +Collapse preserves BlueId. Replacing a verified materialized node with a pure reference to its known BlueId yields the same exact node and the same parent identity. + +Resolution preserves Source-document meaning. A Source Document and its complete Resolved Form derive the same BlueId after the Resolved Form is canonicalized. + +A Resolved Form is not generally direct BlueId Input. It may contain inherited or provider-materialized fields that are derivable from the type chain. Directly hashing it is not guaranteed to produce the Source Document's BlueId. + +### 7.4 BlueId Input (normative) + +**BlueId Input** is any node valid for direct application of the BlueId algorithm after BlueId input normalization. + +BlueId Input MUST NOT contain: + +- the `blue` directive; +- unresolved aliases introduced only for authoring convenience; +- illegal payload combinations; +- invalid list-control forms; +- mixed `blueId` reference shapes; +- unresolved cyclic placeholders such as `this#0`, except inside the explicit cyclic-set calculation API defined in §15; +- `$pos` overlays; +- `null` list elements; +- empty-object list elements that have not been normalized to `$empty: true`. + +A node containing `blue` MUST NOT be accepted as direct BlueId Input. The `blue` directive is never identity content. + +### 7.5 Allowed BlueId forms (normative) + +A **plain BlueId** is the Base58 encoding of a SHA-256 digest using the following alphabet: + +```text +123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz +``` + +Blue Language 1.0 does not define alternative BlueId alphabets. A registry MAY define aliases or packaging metadata, but MUST NOT redefine the BlueId hash alphabet. + +A plain BlueId MUST be the canonical Base58 encoding of exactly 32 bytes, the output length of SHA-256. Implementations MUST reject non-canonical Base58 encodings, strings containing characters outside the BlueId alphabet, and strings that decode to any length other than 32 bytes. + +A plain BlueId MUST NOT contain `#`. The `#` suffix syntax is reserved for cyclic-set member BlueIds. + +A valid unprefixed plain BlueId always denotes the BlueId v1 form defined here. A future incompatible BlueId version MUST use syntax that is not valid as a plain BlueId v1 and MUST NOT reinterpret an existing valid v1 string. + +The ZERO_BLUEID sentinel defined in §15.2 is not a plain BlueId because the character `0` is not in the BlueId alphabet. + +A **cyclic-set member BlueId** has the form: + +```text +# +``` + +where `MASTER` is the plain BlueId of the ordered cyclic set list and `index` is a non-negative decimal integer. + +`this#` is an algorithm-internal placeholder accepted only by the explicit cyclic-set calculation API defined in §15. It MUST NOT appear in ordinary BlueId Input or provider-stored content. + +--- + +## 8. Types, Overlays, and Subtyping + +### 8.1 Any node can be a type (normative) + +There is no schema-versus-instance bifurcation in Blue. Any node can appear under `type`. + +If `T` is used in `type: T`, then `T` contributes: + +- structure; +- nested type chains; +- schema constraints; +- fixed values. + +A type is an **overlay source**, not a class declaration. + +### 8.2 Fixed-value invariant (normative) + +A concrete value embedded in a type is immutable in descendants at that path. A descendant MUST NOT replace, remove, or contradict that value. Any attempted override MUST fail resolution. + +For example, if a type fixes: + +```yaml +country: + value: PL +``` + +then a descendant cannot resolve with: + +```yaml +country: + value: US +``` + +### 8.3 Fixed-value equality (normative) + +Fixed-value equality is evaluated after preprocessing and wrapper normalization. + +- Scalar equality compares the parsed scalar value and effective scalar type. +- Object and list equality compares the BlueId of the normalized subtree. +- `name` and `description` are content for fixed-value equality. Matcher neutrality applies to type/shape matching, not to identity equality of fixed values. + +Scalar payload equality compares parsed scalar value and effective scalar type. Full fixed-node equality compares the normalized Blue node identity, including `name`, `description`, metadata, and payload. Thus a descendant may not change labels on an inherited fixed-value node, because doing so changes the fixed node's identity. + +Therefore these are equal after wrapper normalization: + +```yaml +city: Warsaw +``` + +```yaml +city: + value: Warsaw +``` + +but these are different fixed values because labels are identity content: + +```yaml +city: + name: City + value: Warsaw +``` + +```yaml +city: + name: Location + value: Warsaw +``` + +Valid label override on declaration-only field: + +```yaml +# Parent type +city: + name: City + type: Text + +# Descendant +city: + name: Location + value: Warsaw +``` + +Invalid label override on fixed-value field: + +```yaml +# Parent type +city: + name: City + value: Warsaw + +# Descendant +city: + name: Location + value: Warsaw +``` + +The second case fails because the inherited fixed node includes the label `name: City` as identity content. + +### 8.4 Subtyping and Liskov substitutability (normative) + +When resolving, descendants MUST satisfy: + +1. **No fixed-value override.** Immutable values inherited from types cannot be changed. +2. **Type compatibility.** A descendant type at a path must be equal to or a subtype of the inherited type at that path (§8.4.1). +3. **Additive structure.** Guaranteed fields cannot be deleted. +4. **Collection compatibility.** `itemType`, `keyType`, and `valueType` compatibility must be preserved. + +Every instance of a subtype MUST be substitutable for its parent. + +If `itemType`, `keyType`, or `valueType` is inherited at a path, a descendant that omits the field inherits it. A descendant MAY narrow the inherited type by supplying an equal type or subtype. A descendant MUST NOT widen, remove, or replace the inherited type with an incompatible type. + +Omitting `itemType`, `keyType`, or `valueType` means unconstrained only when there is no inherited effective type constraint at that path. + +### 8.4.1 Formal subtype relation (normative) + +For Blue Language 1.0, `T <: P` ("T is a subtype of P") iff resolving `T` as a descendant overlay of `P` succeeds under the resolution rules in §10, and every valid instance of `T` is substitutable where an instance of `P` is required. + +A subtype check MUST ignore `name` and `description` for matcher/type-shape purposes, but fixed-value equality still includes `name` and `description` because they are identity content (§8.3). + +For each path contributed by parent type `P`, subtype `T` MUST satisfy all of the following: + +1. **Fixed values preserved.** If `P` fixes a scalar, object, list, or subtree value at a path, `T` MUST preserve the same fixed value under §8.3. +2. **Guaranteed structure preserved.** If `P` guarantees a field or list prefix element, `T` MUST keep it present in all valid instances unless a specific list merge rule explicitly refines it without removal. +3. **Schema constraints compatible.** Every schema constraint contributed by `P` MUST remain satisfied by `T`. Additional constraints in `T` are allowed only when their intersection with inherited constraints is non-empty and not weaker. +4. **Type constraints narrowed only.** If `P` declares `type`, `itemType`, `keyType`, or `valueType` at a path, `T` may repeat the same type or provide a subtype. It MUST NOT omit, widen, or replace the inherited effective type constraint with an incompatible type. +5. **Payload kind compatible.** Scalar, list, and object payload kinds MUST remain compatible with inherited guarantees. A subtype MUST NOT turn an inherited scalar requirement into a list/object requirement, or vice versa, unless resolution can prove the inherited requirement is not applicable. +6. **List policies preserved.** An inherited `mergePolicy: append-only` MUST remain append-only. A descendant MUST NOT weaken append-only to positional. If no merge policy is inherited and none is authored, the effective default is positional. + +Equivalently, `T <: P` when the Resolved Form produced by resolving `T` over `P` is valid and does not violate any invariant or guarantee of `P`. + +If checking `T <: P` requires resolving a type chain that revisits a type already on the active resolution stack, resolution MUST fail with a type-cycle error (§10.2.1). + +### 8.4.2 Nominal core type identity (normative) + +The canonical core primitive and collection types `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` are **nominal** Blue Language types identified by their canonical registry BlueIds. + +A type resolving to one of these canonical core types is compatible with another such type only when the canonical registry BlueId is equal, unless the canonical registry explicitly declares a subtype relationship. Blue Language 1.0 declares no implicit subtype relationship between distinct core types. + +Matcher-neutral treatment of `name` and `description` applies to structural field matching and subtype shape checks. It does **not** make two different canonical registry type identities interchangeable. If a core type description changes and therefore the type BlueId changes, it is a different nominal type. + +Examples: + +- The canonical `Integer` type is compatible with itself by registry BlueId. +- A node named `Integer` with a different description and different BlueId is not the canonical `Integer` type. +- `Integer` and `Double` are not subtypes of each other in Blue Language 1.0. + +### 8.5 Instance-as-type (normative) + +Nodes representing individuals can be used as types. + +For example: + +- `Alice` may have `type: Person`. +- `Alice Smith` may have `type: Alice`. + +All fixed values in `Alice` become invariants in `Alice Smith`. Alice's top-level `name` and `description` do not flow to Alice Smith (§4.6). + +### 8.6 Requirement overlays (normative) + +An ancestor may partially constrain a subtree without binding a concrete type at that path. + +Example: + +```yaml +# Parent +name: A +prop1: + x: 1 + schema: + minFields: 1 +``` + +A descendant may later set: + +```yaml +name: B +type: A +prop1: + type: Some +``` + +This is valid only if the merged result still satisfies all overlay obligations, including fixed values and schema constraints. If the overlay had a type, the descendant's type must be equal to or a subtype of that type. + +If the overlay forces `x = 1` but `Some` forces `x = 2`, resolution MUST fail. + +### 8.7 Specialization versus expansion (normative distinction) + +**Expansion** materializes a verified reference to an existing node. It reveals more of the same exact node and MUST preserve BlueId. + +**Specialization** is the authoring act of creating a new node whose `type` points to another node and whose overlay adds compatible, more specific meaning. Specialization is governed by the fixed-value, subtype, merge, and schema rules in this section. A specialized node is not the node it specializes and normally has a different BlueId. + +Example: + +```yaml +# Existing node used as a type +name: Price +amount: + type: Integer +currency: + type: Text +``` + +```yaml +# New specialization +name: PLN Price +type: + blueId: +currency: PLN +``` + +Expanding `` reveals the existing `Price` node. Creating `PLN Price` specializes `Price` and creates a new node. Implementations and documentation MUST NOT use these terms interchangeably. + +The word **extension** remains appropriate for unrelated concepts such as implementation extensions or separately specified preprocessing extensions. In this specification, the formal type-and-overlay concept is **specialization**. + +--- + +## 9. Schema Constraints + +### 9.1 Attaching schema (normative) + +A materialized `schema` object or a pure reference to such an object MAY be attached to any node. An operation that needs the constraints behind a pure reference MUST expand and verify that reference before interpreting the schema. + +All schema constraints accumulate along the type chain. Compatible constraints are intersected according to §9.9. Irreconcilable constraints MUST fail resolution. + +### 9.2 Schema vocabulary (normative) + +Only the keywords listed in §§9.3-9.8 are valid inside a materialized `schema` object. Implementations MUST reject any other key after a referenced schema object has been expanded and verified. The `blueId` key of the pure-reference wrapper is not a schema keyword and is never interpreted as one. + +The valid schema keywords are: + +```text +required, +minItems, maxItems, uniqueItems, +minFields, maxFields, +minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, +minLength, maxLength, +enum +``` + +A schema object MUST NOT contain any key outside this list. + +### 9.2.1 Schema keyword value types (normative) + +| Keyword | Required value shape | +|---|---| +| `required` | boolean | +| `minItems`, `maxItems`, `minFields`, `maxFields`, `minLength`, `maxLength` | non-negative integer in the safe JSON numeric integer range | +| `uniqueItems` | boolean | +| `minimum`, `maximum`, `exclusiveMinimum`, `exclusiveMaximum`, `multipleOf` | numeric scalar or explicit numeric scalar node | +| `enum` | list of scalar values or explicit scalar nodes | + +A schema keyword value with the wrong shape MUST be rejected. Implementations MUST NOT coerce schema keyword values across scalar types. + +### 9.2.2 Schema applicability (normative) + +Each schema keyword applies only to the effective node kind for which it is defined. + +- String constraints apply only to effective Text values. +- Numeric constraints apply only to effective Integer or Double values. +- List constraints apply only to effective list payloads. +- Object field-count constraints apply only to effective object payloads. +- `enum` applies to scalar values unless an explicit scalar-node enum entry is used. +- `required` applies to the child field declaration at the path where it appears. + +If a schema keyword is evaluated against an incompatible effective node kind, validation MUST fail with a schema violation. Implementations MUST NOT silently ignore incompatible schema keywords. + +### 9.2.3 Required fields (normative) + +`required: true` on a child field declaration requires that the field be semantically present in resolved descendants. + +A required field is satisfied only if the resolved child node contains at least one of: + +- a scalar payload `value`; +- a list payload `items`, including an empty list; +- an object payload with at least one ordinary child field; +- a pure reference; +- a fixed payload or fixed subtree inherited from an ancestor type. + +A metadata-only child declaration, such as a node containing only `type`, `schema`, `name`, or `description`, does not by itself satisfy `required: true`. + +If a field is required but has no semantic payload or fixed inherited content after resolution and cleaning, validation MUST fail. + +### 9.2.4 Field counting (normative) + +`minFields` and `maxFields` count ordinary child fields of the effective object payload after resolution and object-field cleaning. + +Reserved language fields such as `name`, `description`, `type`, `schema`, `contracts`, `value`, and `items` do not count as ordinary fields. + +Fields removed by object-field cleaning do not count. Inherited ordinary child fields that are materialized in the Resolved Form do count. + +### 9.3 Presence + +```yaml +required: true +``` + +When a schema with `required: true` is attached to a child field in a type or object overlay, that field MUST be semantically present in resolved descendants according to §9.2.3. If used at a document root, `required` is trivially satisfied by the existence of the root node. + +### 9.4 Lists + +```yaml +minItems: +maxItems: +uniqueItems: true | false +``` + +`maxItems` MUST be greater than or equal to `minItems` when both are present. + +`uniqueItems: true` compares items by item BlueId, not by textual rendering. + +### 9.5 Objects + +```yaml +minFields: +maxFields: +``` + +`maxFields` MUST be greater than or equal to `minFields` when both are present. + +The term **fields** is used because Blue objects have direct ordinary fields and no `properties` wrapper. + +### 9.5.1 Dictionary direct encoding validation (normative) + +For direct Dictionary object encoding, each direct key MUST be valid under the effective `keyType`. + +For direct object encoding, `keyType` MUST resolve to one of the scalar key types with a canonical textual representation: Text, Integer, Double, or Boolean. If `keyType` is omitted and no effective `keyType` is inherited, it defaults to Text. + +A key's serialized object-member name MUST be exactly the canonical textual form of the parsed key value. If two key values canonicalize to the same object-member string, the document has a duplicate key conflict and MUST be rejected. + +Every value in a Dictionary with an effective `valueType` MUST resolve as an instance of, or subtype-compatible with, the effective `valueType`. + +Applications needing arbitrary non-scalar keys or reserved-key collisions MUST use an application-defined escaped representation rather than direct object encoding. + +### 9.6 Numerics + +```yaml +minimum: number +maximum: number +exclusiveMinimum: number +exclusiveMaximum: number +multipleOf: number +``` + +Numeric schema keyword values MAY be authored in either scalar form or explicit scalar-node form. + +Scalar form: + +```yaml +schema: + minimum: 5 +``` + +Explicit scalar-node form: + +```yaml +schema: + minimum: + type: Integer + value: "9007199254740992" +``` + +A quoted decimal string without explicit `type: Integer` is Text and MUST NOT be accepted as a numeric constraint. + +Rules: + +- `minimum: m` means the numeric value must be greater than or equal to `m`. +- `maximum: m` means the numeric value must be less than or equal to `m`. +- `exclusiveMinimum: m` means the numeric value must be strictly greater than `m`. +- `exclusiveMaximum: m` means the numeric value must be strictly less than `m`. +- `multipleOf` must be greater than zero. + +If multiple numeric constraints appear in the type chain, the value must satisfy all of them. For integer `multipleOf` constraints, implementations MUST combine compatible constraints using least common multiple (LCM). The effective merged schema MUST contain one `multipleOf` value equal to that LCM, and the Resolved Form and Canonical Identity Input MUST NOT preserve an implementation-specific list of equivalent integer `multipleOf` constraints. + +For `Double` `multipleOf`, both the tested value and the `multipleOf` constraint are interpreted as their exact IEEE 754 binary64 rational values after parsing. A Double value `v` satisfies `multipleOf: m` iff `m > 0` and the exact rational quotient `v / m` is an integer. Implementations MUST NOT use epsilon comparisons, decimal string rounding, host-language modulo on binary floating point, or implementation-specific approximation. + +For cross-type numeric comparisons, an `Integer` value is interpreted as an exact rational integer. A `Double` bound or value is interpreted as its exact IEEE 754 binary64 rational value. Comparison between Integer and Double uses exact rational comparison. + +A numeric token that cannot be parsed to a finite IEEE 754 binary64 value under §2.4 is invalid before schema evaluation. + +Implementations MAY use arbitrary-precision rational arithmetic internally to implement these predicates. They MUST NOT expose host floating-point rounding differences in conformance behavior. + +Numeric schema keyword values follow the same numeric representation rules as scalar values (§2.4). Integer constraints outside the safe JSON numeric integer range MUST be represented as typed Integer scalar nodes that preserve exact integer identity. Quoted decimal text without explicit Integer typing is Text and MUST NOT be treated as a numeric schema constraint. + +### 9.7 Strings + +```yaml +minLength: +maxLength: +``` + +Length is measured in Unicode code points. `maxLength` MUST be greater than or equal to `minLength` when both are present. + +### 9.8 Enumerations + +```yaml +enum: [v1, v2, ...] +``` + +Enumeration values are scalar Blue values. They MAY be authored as bare scalars when unambiguous, or as explicit scalar nodes with `type` and `value` when type disambiguation is required, for example for large integers represented as quoted canonical decimal text. Equality is by parsed scalar value, effective scalar type, and canonical JSON value semantics, not by textual rendering. + +`enum` comparison is performed after preprocessing and scalar type inference. Therefore the untyped enum entry `1` is an `Integer`, while `1.0` and `1e0` are `Double`. A quoted decimal string is Text unless authored as an explicit `Integer` scalar node. + +Example with a large integer enum value: + +```yaml +schema: + enum: + - 1 + - 1.0 + - type: Integer + value: "9007199254740992" +``` + +The first two enum entries above are distinct because their effective scalar types are different. + +There is no separate `const` keyword. A fixed value in a type enforces a constant. + +### 9.8.1 Enumeration normalization (normative) + +`enum` is a set of allowed scalar identities. Authoring order is not semantic. + +During schema validation, schema merge, and canonicalization, each enum entry MUST be normalized to its typed scalar identity: effective scalar type plus canonical scalar value. Duplicate entries with the same typed scalar identity are redundant and MUST be removed in the effective schema. + +The canonical enum representation MUST sort entries by the RFC 8785 canonical JSON byte sequence of their typed scalar identity form. If two entries have identical canonical bytes, they are duplicates and only one is retained. + +Therefore these schemas are semantically equivalent and MUST canonicalize identically: + +```yaml +schema: + enum: [A, B] +``` + +```yaml +schema: + enum: [B, A, A] +``` + +The effective canonical enum contains `A` and `B` once each, in the canonical ordering defined above. + +### 9.9 Schema merge rules (normative) + +When schemas accumulate along the type chain, implementations MUST merge keyword constraints as follows: + +| Keyword | Merge rule | Failure case | +|---|---|---| +| `required` | logical OR | never, for the keyword itself | +| `minItems` | maximum | merged `minItems > maxItems` | +| `maxItems` | minimum | merged `maxItems < minItems` | +| `uniqueItems` | logical OR | never, for the keyword itself | +| `minFields` | maximum | merged `minFields > maxFields` | +| `maxFields` | minimum | merged `maxFields < minFields` | +| `minimum` | strongest lower bound | incompatible with upper bounds | +| `maximum` | strongest upper bound | incompatible with lower bounds | +| `exclusiveMinimum` | strongest exclusive lower bound | incompatible with upper bounds | +| `exclusiveMaximum` | strongest exclusive upper bound | incompatible with lower bounds | +| `multipleOf` | all constraints must hold; integer constraints MUST be merged to their LCM; Double constraints MUST be evaluated by exact rational arithmetic over IEEE 754 binary64 values under §9.6 | no possible numeric value satisfies all constraints | +| `minLength` | maximum | merged `minLength > maxLength` | +| `maxLength` | minimum | merged `maxLength < minLength` | +| `enum` | normalize both sides under §9.8.1, then intersect by typed scalar identity; canonical effective enum is duplicate-free and sorted under §9.8.1 | empty intersection | + +For lower/upper-bound interactions, an exclusive bound at the same numeric value is stricter than an inclusive bound. For example, `minimum: 5` merged with `exclusiveMinimum: 5` yields `exclusiveMinimum: 5`. + +--- + +## 10. Resolution + +### 10.1 Resolution (normative) + +**Resolution** applies Blue type and overlay semantics to a Source Node. It follows effective type links, merges inherited and instance contributions, enforces fixed values, applies list merge rules, accumulates schema constraints, and validates the resolved result. + +A **complete Resolved Form** contains the complete semantic result for the root being resolved. + +A **limited resolution result** contains only explicitly demanded paths and the supporting content needed to establish them. It is an operation result, not a different Blue node. Coverage and completeness information are out-of-band and do not affect BlueId. + +For every path covered by limited resolution, the resulting value, effective type, and applicable constraints MUST be exactly the same as in complete resolution of the same source with the same provider content. + +A complete Resolved Form is the input to minimization and canonicalization. An incomplete result MUST NOT be used to calculate a Source Document's BlueId, claim complete schema validity, or produce a whole-node Minimized Overlay. + +### 10.2 Complete resolution algorithm (normative) + +Given a Source Node `S`, complete resolution performs: + +1. **Preprocess** `S` (§6), producing a Preprocessed Document. +2. **Resolve the type chain.** If `S.type` exists, recursively resolve it. If the type is a pure reference, expand it through a provider and verify the fetched content (§12.4). The result is the ancestor Resolved Form `A`. +3. **Merge ancestor and source.** Merge `A` into target `T`, then merge `S` into `T`: + - **Root labels:** when merging a type into an instance root, do not copy the type root's `name` or `description` onto the instance root (§4.6). + - **Values:** copy if absent; if both are present, they must be equal under fixed-value equality (§8.3). + - **Types:** assign and propagate under §8. + - **Schema:** accumulate under §9. + - **Object fields:** merge recursively; children must remain compatible. + - **Lists:** merge under §11. + - **Contracts:** preserve and merge as identity-bearing content under §4.4; do not execute. +4. **Validate schema** after merging. +5. **Produce the complete Resolved Form.** Implementations MAY freeze it into an immutable snapshot when needed. + +Schema validation is performed after inherited and instance values are merged at a node. Therefore an inherited schema applies to inherited fixed values, type-derived fields, and instance-supplied values in the final Resolved Form. + +Type-chain resolution is depth-first: the effective ancestor type is resolved before it is merged into the descendant target. A resolver MUST track the active type-resolution stack for cycle detection. + +### 10.2.1 Type-chain cycle detection (normative) + +Type-chain cycles are invalid for Blue Language 1.0 resolution. + +If resolving a node requires resolving a type that is already present on the active type-resolution stack, resolution MUST fail deterministically with a type-cycle error. + +Example invalid cycle: + +```yaml +# A +name: A +type: + blueId: + +# B +name: B +type: + blueId: +``` + +Circular-set BlueIds (§15) identify cyclic document sets. They do not make cyclic inheritance or cyclic type chains resolvable. Blue Language 1.0 does not define fixed-point type semantics. + +### 10.2.2 Complete resolution pseudocode (informative) + +```text +resolve_complete(source, provider): + S = preprocess(source) + if S.type exists: + T_ref = normalize_type_reference(S.type) + T_node = expand_reference(T_ref, provider) + A = resolve_complete(T_node, provider) + else: + A = empty node + R = merge_as_instance(ancestor=A, instance=S, path="/") + validate_schema_recursively(R) + return ResolvedForm(R, provenance, complete=true) + +merge_as_instance(ancestor, instance, path): + T = copy_type_derived_content(ancestor, path) + if path == "/" and ancestor is the effective type of instance: + do not copy ancestor.name or ancestor.description to T + merge reserved metadata using field-specific rules + merge ordinary child fields recursively + merge lists using §11 + merge contracts using §4.4 + reject fixed-value, type, schema, or payload-kind conflicts + record provenance for each retained contribution + return T +``` + +Precise implementation structure is not normative. The observable complete Resolved Form, validation behavior, canonicalization provenance, and the resulting Source-derived BlueId are normative. + +### 10.3 Limited resolution (normative) + +A resolver MAY accept out-of-band **Limits** that identify demanded paths or bound work. Typical limits include selected operation paths, maximum reference expansions, maximum graph depth, and maximum nodes visited. + +For a requested path, limited resolution MUST resolve the complete semantic dependency closure required to establish that path. This may include: + +- the source node and ancestors along the path; +- effective type nodes and inherited fields contributing at the path; +- applicable schema and collection constraints; +- object keys or list positions required by the requested operation; +- provider content needed to verify and interpret those contributions. + +A limited resolver MUST NOT: + +- treat an unexpanded reference as an empty object or missing field; +- report a field as semantically absent unless absence has been established from the required source and type contributions; +- return a guessed value when a limit prevents completion; +- expose provider, cache, or storage layout as semantic content. + +When limits prevent a demanded result from being established, the operation MUST fail with a deterministic limit/incomplete result or explicitly report that the requested path is incomplete. It MUST NOT return a normal successful absence result. + +Implementations may return demanded values directly or may return a partially materialized result with out-of-band coverage metadata. In either case, all covered values MUST equal complete resolution. + +### 10.4 Resolution provenance (normative) + +A conforming implementation performing complete resolution for canonicalization MUST track enough provenance to canonicalize deterministically. For each resolved path, it MUST be able to determine whether content was: + +- **instance-supplied** by the Source Document after preprocessing; +- **type-derived** from an ancestor type; +- **provider-materialized** from a `blueId` reference; +- **preprocessing-derived** from mandatory or declared preprocessing; +- **merge-derived** from compatible instance and type contributions. + +Limited resolution need track only the provenance required for its covered paths, unless the result will later be completed for canonicalization or minimization. + +The exact internal representation is implementation-defined. + +### 10.5 Identity guarantee (normative) + +Resolution preserves semantic identity. A Source Document and its complete Resolved Form derive the same BlueId when the complete Resolved Form is canonicalized. + +Implementations MUST NOT assume that directly hashing a Resolved Form produces the Source Document's BlueId. + +Limited resolution does not create a new identity. It exposes only part of the semantics of the same source node. + +### 10.6 Provider failures (normative) + +A conforming implementation MUST expand referenced content when that content is required for the requested resolution, canonicalization, minimization, collapse verification, or validation. If required content is unavailable or fails verification, the operation MUST fail deterministically. Implementations MUST NOT silently substitute empty content for missing references. + +Unrelated references outside the demanded dependency closure need not be fetched. + +### 10.7 Limits (normative) + +Limits are out-of-band operation controls. They MUST NOT be serialized into the Blue node, included in BlueId calculation, or alter the result that complete processing would produce. + +An implementation SHOULD support path, depth, node-count, and reference-count limits for expansion and resolution of large graphs. + +A result is complete only when every path and constraint required by the requested operation has been established. An incomplete result MUST NOT be used for whole-node Source Document BlueId calculation, whole-node minimization, or a claim of complete validation. + + +### 10.8 Demand-limited operation outcomes (normative) + +A demand-limited Language operation asks a semantic question about one or more selected paths without requiring complete graph expansion or complete document resolution. + +Common demands include exact node identity, node kind, semantic existence, one object child, complete object keys, list length, one list item, effective type, applicable constraints, or the resolved value at a path. + +The exact host-language API is not normative. A conforming operation MUST deterministically establish exactly one of these semantic conclusions: + +- the requested result is established for the declared coverage; +- semantic absence is established from sufficient direct and inherited information; +- the request could not be completed because a limit, unavailable reference, unsupported provider operation, or another explicitly reported condition prevented proof; +- the demanded content or its required semantic closure is invalid. + +Implementations MAY expose named result variants such as `Established`, `Absent`, `Incomplete`, and `Invalid`, but this specification does not require those class names or one particular public API. + +Rules: + +- a pure reference, cache miss, provider timeout, direct-node limit, or resolution limit MUST NOT be treated as semantic absence; +- a result established from graph-equivalent inline, collapsed, expanded, cached, or segmented forms MUST be the same once the same logical identities are available; +- a result that did not establish complete required coverage MUST NOT be used for whole-node canonicalization, Source Document BlueId calculation, complete minimization, or a claim of complete validation; +- diagnostic information about outstanding identities or covered paths is out-of-band and does not affect Blue content or identity. + +### 10.9 Cache neutrality and diagnostic information (normative) + +A Language implementation MAY expose diagnostic information such as demanded identities, covered paths, provider outcomes, semantic steps, or implementation timings. + +Such diagnostics are not Blue content and do not affect identity. Cache state, prefetching, batching, storage pages, or previous operations MUST NOT change a successful semantic result or turn incomplete evidence into complete evidence. + +Layered runtime specifications MAY define their own deterministic work ledger over Language operations. Such a ledger is not part of Blue content-language identity and MUST NOT redefine the semantic outcomes in §10.8. + +## 11. Lists, Merge Policies, and List Control Forms + +### 11.1 Authoring model (normative) + +A list field SHOULD be authored in typed form when list semantics matter: + +```yaml +: + type: List + itemType: + mergePolicy: append-only | positional + items: + - ...elements... +``` + +A surface list is permitted for simple cases: + +```yaml +tags: [a, b, c] +``` + +Typed form is REQUIRED when `mergePolicy`, anchors, or overlays are used. + +Every element of a resolved list with an effective `itemType` MUST resolve as an instance of, or subtype-compatible with, the effective `itemType`. If an item cannot be resolved or is incompatible with `itemType`, validation MUST fail. + +If `itemType` is omitted and no effective inherited `itemType` exists, list elements are unconstrained by item type. + +### 11.2 Allowed item forms inside `items` (normative) + +Each item inside `items` MUST be exactly one of the following forms after Source Document preprocessing. + +#### Normal element + +```yaml +- +``` + +A normal element is content. + +#### Append anchor + +```yaml +- $previous: + blueId: +``` + +Rules: + +- `$previous` is allowed only as the first item. +- The shape MUST be exactly one top-level `$previous` key whose value is an object with exactly one `blueId` key. +- `$previous` is never content. + +#### Positional overlay + +Map overlay: + +```yaml +- $pos: 1 + ...overlay fields... +``` + +Replacement overlay for an object: + +```yaml +- $pos: 1 + $replace: + type: Address + city: Warsaw +``` + +Replacement overlay for a list: + +```yaml +- $pos: 1 + $replace: + items: + - A + - B +``` + +Replacement overlay for a pure reference: + +```yaml +- $pos: 1 + $replace: + blueId: X +``` + +Rules: + +- `$pos` MUST be a non-negative integer using zero-based indexing. +- `$pos` is valid only when `mergePolicy: positional`. +- A `$pos` item without `$replace` is a map overlay. It is valid only when the inherited element at that index is an object-compatible node. If the inherited element is scalar, list, or pure reference, the overlay MUST use `$replace` and remain type-compatible. +- `$pos` overlays are consumed by resolution and do not appear as content in the final list. +- `$replace` is valid only inside a `$pos` item. Its value is a full Blue node used to replace the inherited element, subject to type and schema compatibility. +- For scalar replacement, the concise form below is equivalent to `$replace: { value: B }`: + +```yaml +- $pos: 1 + value: B +``` + +The `value` form MUST NOT be used to carry list or object replacements. Use `$replace` for non-scalar replacements. + +#### Placeholder element + +```yaml +- $empty: true +``` + +`$empty: true` is content. It is a real element that occupies a position and affects BlueId. It is distinct from `null`, `{}`, and `[]`. + +The shape MUST be exactly one top-level `$empty` key whose value is the boolean `true`. `$empty: false`, `$empty: null`, and `$empty` with sibling fields are invalid as list placeholder elements. + +### 11.3 Scope of list control keys (normative) + +The special keys `$previous`, `$pos`, `$replace`, and `$empty` are recognized only as top-level keys of elements inside a list payload. + +`$empty` is valid in any list payload. + +`$previous`, `$pos`, and `$replace` are list overlay controls. They are valid only when the list is being resolved as a typed or overlay-capable list. Authors SHOULD use the typed list form when using these controls. + +Outside list-control position, `$previous`, `$pos`, `$replace`, and `$empty` are ordinary field names unless another specification gives them meaning. They do not act as list controls outside list elements. + +### 11.4 Default merge policy (normative) + +If no effective `mergePolicy` is inherited and no `mergePolicy` is authored on the list, resolvers MUST assume: + +```yaml +mergePolicy: positional +``` + +If an inherited list has an effective `mergePolicy`, a descendant list overlay that omits `mergePolicy` inherits that effective policy. A descendant MAY repeat the same `mergePolicy`. + +A descendant MUST NOT change an inherited `mergePolicy`. If an effective `mergePolicy` is inherited, omission by the descendant means inheritance, not defaulting. If no policy is inherited and no policy is authored, the effective default is `positional`. + +In particular, `append-only` MUST NOT be weakened to `positional`. + +For histories, ledgers, timelines, and append-only logs, authors MUST specify: + +```yaml +mergePolicy: append-only +``` + +### 11.5 Semantics of `null`, `{}`, `[]`, and `$empty` (normative) + +Blue distinguishes object-field absence from list position. + +#### Object fields + +In object fields, `null` means no information. Before hashing: + +- fields whose value is `null` MUST be omitted; +- fields whose value normalizes to an empty object `{}` MUST be omitted; +- empty lists `[]` MUST be preserved. + +This removal is recursive and may cascade. + +#### List elements + +List elements are positional. Implementations MUST NOT delete list elements during cleaning, because doing so changes list length and shifts later indices. + +In Source Documents, a list element that is `null`, an empty object `{}`, or an object that recursively normalizes to an empty object after object-field cleaning MUST be normalized to: + +```yaml +$empty: true +``` + +It MUST NOT be deleted from the list, because list position is content. + +In Canonical Identity Input and BlueId Input, `null` list elements and empty-object list elements MUST NOT appear. They MUST already have been normalized to `$empty: true` or rejected. + +The marker `$empty: true` is content. It occupies a list position and affects BlueId. + +Empty lists `[]` are preserved as list elements and are distinct from `$empty: true`. + +Consequences: + +```text +id([A, null, B] after preprocessing) == id([A, {$empty: true}, B]) +id([A, null, B] after preprocessing) != id([A, B]) +id([A, {}, B] after preprocessing) == id([A, {$empty: true}, B]) +id([A, [], B]) != id([A, {$empty: true}, B]) +``` + +### 11.6 Merge semantics (normative) + +Let `P` be the resolved parent list and `C` be the child overlay list. + +#### `append-only` + +For `mergePolicy: append-only`: + +- inherited indices `< length(P)` MUST NOT be modified or deleted; +- `$pos` overlays are forbidden; +- normal items after the inherited prefix are appended; +- an optional `$previous` anchor may appear as the first child item. + +Errors: + +- any `$pos` overlay; +- malformed `$previous`; +- `$previous` not first; +- repeated `$previous`; +- attempted modification, removal, or reordering of the inherited prefix. + +#### `positional` + +For `mergePolicy: positional`: + +- `$pos: i` refines inherited index `i`, where `0 <= i < length(P)`; +- map overlays merge field-wise, subject to type and schema compatibility; +- `$replace` overlays replace the inherited element, subject to compatibility; +- scalar `value` overlays replace the inherited element with a scalar node, subject to compatibility; +- normal items without `$pos` are appended after the inherited prefix in author order; +- reordering, removal, and gaps within the inherited prefix are forbidden. + +Errors: + +- `$pos` missing or non-integer; +- `$pos` out of range; +- duplicate overlays for the same index; +- type or schema incompatibility at the index; +- attempted reordering or removal of parent elements; +- `value` used as a non-scalar positional replacement. + +### 11.7 `$previous` validation (normative) + +`$previous` is a resolution-time anchor. + +During resolution, the resolver MUST verify that the inherited prefix hashes to `$previous.blueId`. If it does not match, resolution MUST fail. + +During direct BlueId calculation of valid BlueId Input that already contains a leading `$previous`, the anchor MAY be used as a list-fold seed (§14.8). Validity of the anchor is a precondition of the input. An implementation performing direct BlueId calculation without resolution context MAY reject `$previous` inputs. + +A direct hasher MUST NOT silently ignore `$previous` and recompute when it cannot verify the prefix. A direct hasher has no provider or inheritance context and therefore cannot determine whether an anchor is stale. + +`$previous` does not define a different list identity algorithm. It exposes a prefix identity that, once verified, may be used as the seed of the ordinary list fold. If the inherited prefix is `[a1, ..., an]` and `$previous.blueId` is verified as `id([a1, ..., an])`, appending `b1, ..., bk` requires only `k` additional fold steps after the BlueIds of the appended elements are established.

Such a provider verifies returned content by running Source Document BlueId calculation, not direct BlueId calculation. The provider mode MUST bind the exact Blue Language release, preprocessing environment, canonical registry bindings, and the exact Source Document snapshot or other identity-bearing evidence being resolved. Ambient provider state is never part of Source Document BlueId calculation. A Source Document provider is not the default portable provider model. + +### 12.4 Plain BlueId provider verification (normative) + +For an ordinary BlueId `X`, provider content is valid only if direct BlueId calculation over the returned BlueId Input produces `X`. + +If verification fails, the demanding operation MUST fail deterministically. + +Implementations MUST NOT silently use provider content whose computed BlueId differs from the requested BlueId. + +### 12.5 Cyclic-set member provider verification (normative) + +A cyclic member BlueId `#` is verified in the context of its complete declared cyclic set under §15. The provider or caller must supply enough context to reconstruct and verify the set. + +An implementation MUST NOT verify `#` by hashing the returned member alone. + +### 12.6 Expansion (normative) + +**Expansion** replaces selected pure references with verified materialized content. + +Given: + +```yaml +field: + blueId: X +``` + +expansion fetches content for `X`, verifies it (§12.4), and makes that content available at `field`. Nested references remain collapsed unless they are also demanded by the operation and permitted by its Limits. + +Expansion may begin at a document root that is itself a pure reference. + +Expansion changes representation, not meaning. It MUST preserve BlueId. A pure reference contributes its target BlueId, and verified materialized content contributes that same identity. + +A conforming expansion API SHOULD accept operation paths and limits. Its **semantic demand closure** MUST contain only references needed for the requested result. References left outside that closure, or left collapsed because of a limit, MUST NOT be treated as absent content. + +An implementation MAY physically prefetch additional verified nodes. Prefetched content outside the semantic demand closure MUST NOT enter the operation result, change completeness, affect identity, or alter a layered portable work ledger. Provider caching, internal paging, and physical storage chunks are implementation details and MUST NOT change the expanded result. + +### 12.7 Collapse (normative) + +**Collapse** replaces selected materialized content with a pure reference `{ blueId: X }` to the same node. + +Collapse is permitted when the node's BlueId is known or has been calculated and, for provider-originated content, verification established that identity. The collapsed result MUST be a pure reference with no sibling fields. + +Collapse changes representation, not meaning, and MUST preserve the enclosing node's BlueId. + +An implementation MAY collapse the document root, an object field, a list element, a type node, a workflow body, or any other complete Blue node. It MAY leave other parts materialized. + +### 12.8 Expansion, resolution, and limits (normative) + +Expansion and resolution are composable but distinct: + +- expansion obtains referenced node content; +- resolution interprets type and overlay semantics; +- a resolver expands only references needed for the demanded semantic result; +- unrelated branches may remain collapsed in a successful operation result when their identity is sufficient and their internal content is not needed by that operation; +- a limited result MUST explicitly report incompleteness when demanded semantics cannot be established. + +Limits affect work, not meaning. The same demanded path resolved from an inline node and from a verified pure reference MUST produce the same value and effective type. + +### 12.9 Graph boundary (normative) + +A Blue Document need not be a closed tree. A `{ blueId: ... }` reference may point outside the serialized document. Implementations materialize referenced content only as needed and within configured limits. + +The fact that a referenced node is stored in another file, database row, object-store chunk, or network location has no Blue Language meaning. + +### 12.10 Blue Language operation paths (normative when exposed) + +Blue Language operation paths are out-of-band selectors used for expansion limits, collapse selection, limited resolution, diagnostics, and provenance. They are not Blue content and do not affect BlueId. + +A conforming implementation that exposes path-limited operations MUST support RFC 6901 JSON Pointer paths over the abstract Blue node model: + +- the empty string `""` selects the root node; +- `/field` selects an object field named `field`; +- `/items/0` selects list payload item index `0` in the abstract node model; +- `~0` represents `~`, and `~1` represents `/`, following RFC 6901. + +The wildcard `*`, such as `/spent/*`, is not part of the required Blue Language 1.0 path grammar. Implementations MAY support wildcards as an extension, but portable conformance fixtures MUST use RFC 6901 paths unless a future path-selector specification defines more. + +### 12.11 Direct-node materialization pattern (informative) + +An implementation may keep one selected node materialized while collapsing any or all complete direct children to pure references. This is ordinary expansion and collapse with a depth or path limit; it is not a fifth Language operation or a new node form. + +For an object, such a representation normally retains the complete direct key set, inline identity-bearing metadata such as `name`, `description`, and scalar `value`, and the exact BlueId of every other direct child. For a list, it normally retains list metadata and the ordered exact BlueId of every direct element. Metadata-only nodes, including nodes carrying `type`, `schema`, `mergePolicy`, or `contracts`, follow the same rule: direct identity-bearing content remains available and complete child nodes may be collapsed. + +This representation has the same BlueId as the fully materialized node. Under the map and list hashing rules in §14, the selected direct node can be verified without fetching transitive descendant bodies. This is the language-level reason path-by-path graph navigation is possible. + +### 12.12 Provider and storage guidance (informative) + +A content-addressed provider can support practical lazy expansion by storing every admitted node in direct-node materialization pattern, keyed by exact BlueId, and fetching one direct node at a time along a demanded path. + +A useful provider distinguishes: + +```text +Found verified exact node content is available +NotFound definitive absence in the provider's declared domain +Unavailable transient infrastructure failure +InvalidEvidence returned content failed verification +``` + +These outcomes are provider or host concerns. `NotFound` and `Unavailable` do not mean that a graph path is semantically absent. Provider transport, batching, authorization, storage layout, and retry rules are outside this Language specification. + +The current BlueId algorithm requires a complete direct manifest to verify an ordinary object or list node. It does not provide logarithmic proofs for one member of a very wide direct container. Applications requiring large mutable maps, vectors, text, or blobs SHOULD use bounded-fanout content-addressed structures. + +## 13. Canonicalization and Minimization + +### 13.1 Distinction (normative) + +Blue defines two operations that may both remove explicit content but serve different purposes. + +**Minimization** takes a complete Resolved Form and produces a smaller Source overlay that resolves back to the same complete Resolved Form. Resolution and minimization are semantic counterparts. A minimizer may choose among several valid Source encodings, so minimization is not necessarily unique. + +**Canonicalization** derives the one deterministic BlueId Input used to calculate the BlueId of a Source Document. Canonicalization is an identity operation, not an authoring preference and not necessarily the smallest serialized form. + +The distinction is: + +| Question | Canonicalization | Minimization | +|---|---|---| +| Purpose | Produce identity input | Produce convenient Source form | +| Input | Complete Resolved Form | Complete Resolved Form | +| Output | Canonical Identity Input | Minimized Overlay | +| Unique | Yes | Not necessarily | +| Valid direct BlueId Input | Yes | Not necessarily | +| May contain `$previous`, `$pos`, `$replace` | No | Yes, when valid Source controls | +| Used in Source Document BlueId calculation | Yes | No | +| Must re-resolve as ordinary Source | No | Yes | + +The Source Document BlueId path is: + +```text +complete Resolved Form + -> canonicalize + -> Canonical Identity Input + -> BlueId algorithm + -> Source-derived BlueId +``` + +The optional authoring path is: + +```text +complete Resolved Form + -> minimize + -> Minimized Overlay + -> when processed again: preprocess -> resolve -> canonicalize -> hash + -> same Source-derived BlueId +``` + +**Minimization is not a step in Source Document BlueId calculation.** A runtime processor does not need to minimize a whole document after every read or patch. It may preserve unchanged nodes by BlueId and use ordinary collapse. Whole-node minimization is needed only when a reduced Source overlay is requested. + +### 13.2 Canonical Identity Input (normative) + +A **Canonical Identity Input** is the deterministic identity form derived from a complete Resolved Form. It contains the deterministic identity-bearing content needed for BlueId calculation. It may contain final canonical payloads, including final list payloads, that are not ordinary Source overlays. A Canonical Identity Input MUST be valid BlueId Input. It is not required to be accepted as a Source Document or to re-resolve under ordinary Source overlay semantics. + +The BlueId derived from a Source Document is the BlueId of its Canonical Identity Input. `Content BlueId` is permitted shorthand for that result, not a separate identifier kind. + +**Blue semantic canonicalization** in this section derives the Canonical Identity Input. **RFC 8785 canonical JSON serialization** is a later byte-serialization rule used inside the BlueId algorithm (§14.1). They are distinct operations: semantic canonicalization decides *what exact Blue node is hashed*; RFC 8785 decides *how helper values are serialized deterministically while hashing it*. + +A Canonical Identity Input is unique for a given complete Resolved Form under the selected Blue Language release and canonical registry bindings. The provider may be needed to obtain verified referenced nodes, but its cache, location, response order, availability history, and other ambient state do not participate in canonical identity. + +### 13.3 Minimized Overlay (normative) + +A **Minimized Overlay** is an author-facing reduced Source overlay that re-resolves to the same complete Resolved Form. + +A conforming implementation MUST implement canonicalization. A conforming implementation MAY expose minimization. If it does, every whole-node Minimized Overlay it produces MUST be based on a complete Resolved Form, MUST re-resolve to that same form, and MUST derive the same BlueId through the full Source Document identity pipeline. + +Different minimizers MAY produce different valid Minimized Overlays. Such overlays MAY have different direct BlueIds, but when processed through the full Source Document identity pipeline they MUST derive the same BlueId. + +A Minimized Overlay MAY use authoring controls such as `$previous`, `$pos`, and `$replace` when valid, and MAY collapse complete subtrees to verified pure references under §13.7. + +### 13.3.1 Why list minimization and canonicalization differ (informative) + +Assume an inherited append-only list contributes: + +```yaml +items: + - A + - B +``` + +and the specialized Source adds `C`. The complete Resolved Form contains: + +```yaml +items: + - A + - B + - C +``` + +A useful Minimized Overlay may retain only the relationship to the inherited prefix and the new item: + +```yaml +items: + - $previous: + blueId: + - C +``` + +That is compact Source syntax. It is not the canonical identity form. + +The Canonical Identity Input MUST contain the final list payload and no overlay controls: + +```yaml +items: + - A + - B + - C +``` + +Similarly, a positional Minimized Overlay may use `$pos` to describe only a changed inherited position, while canonicalization applies the overlay and writes the final ordinary list payload. This is why the correct identity pipeline is `resolve -> canonicalize -> BlueId`, not `resolve -> minimize -> BlueId`. + +### 13.4 Canonicalization requirements (normative) + +Given a Resolved Form `R`, canonicalization MUST: + +- preserve all instance contributions that are not derivable from the type chain; +- remove fields fully derivable from the type chain; +- preserve instance-level `name` and `description` when present on the instance; +- not inherit top-level `name` or `description` from the type; +- preserve instance-fixed values that are not derivable from the type chain; +- replace materialized type objects with canonical `type: { blueId: ... }` references when their BlueId is known; +- ensure the Canonical Identity Input contains no type aliases; if an instance supplied a type alias, preprocessing MUST replace it with the canonical `type: { blueId: ... }` reference before resolution; +- for provider-materialized content, preserve the original pure reference when that reference is an instance contribution and the materialized subtree contributes no additional instance-supplied content; +- remove the `blue` directive if present, because it is invalid after preprocessing; +- normalize list placeholders so that list `null` and empty-object elements become `$empty: true`; +- consume all `$pos` overlays and produce final canonical list content; +- produce valid BlueId Input. + +Schema objects included in Canonical Identity Input MUST use normalized effective schema form. In particular, `enum` values are duplicate-free and sorted under §9.8.1, and integer `multipleOf` constraints are represented by the merged LCM value rather than by raw inherited/descendant contributions. + +### 13.5 Canonicalization as deterministic diff (normative) + +Canonicalization can be understood as a deterministic diff between the Resolved Form and the resolved ancestor form contributed by the effective type chain. + +For each node: + +1. If the node has an effective type, include the canonical type reference unless the type reference itself is fully derivable at that path and not required by the canonical identity form. +2. For each reserved metadata field other than `type`, include it only when it is an instance contribution that is not derivable from the ancestor form, except where this specification requires preservation. +3. For each ordinary child field, omit it when the child is fully derivable from the ancestor form. Otherwise include the canonical identity input of the child. +4. For scalar values, omit an inherited fixed value and include an instance value not derivable from the ancestor. +5. For lists, use the canonical list rules in §13.6. +6. After the identity input is constructed, apply BlueId input normalization and object-field cleaning. Empty object fields are omitted. Empty lists are preserved. + +Implementations MUST make all tie-breakers deterministic and covered by conformance vectors. + +### 13.5.1 Canonicalization tie-breakers (normative) + +When multiple candidate identity inputs would represent the same Resolved Form, the Canonical Identity Input MUST be selected by the following tie-breakers, in order: + +1. **Omit derivable non-list content.** A field, metadata entry, or non-list subtree that is fully derivable from the effective type chain MUST be omitted from the Canonical Identity Input, unless another rule in this section explicitly requires it. **List payloads are special:** for list nodes, §13.6 overrides this general omission rule. Canonicalization of a list produces the final canonical list payload for identity calculation, including inherited prefix elements, positional refinements, append-only appends, and `$empty` placeholders after normalization. +2. **Preserve non-derivable instance content.** Content supplied by the instance or Source Document and not derivable from the type chain MUST be preserved. +3. **Use pure references for referenced ancestors/types.** A materialized type or referenced ancestor whose BlueId is known MUST be represented as `{ blueId: X }` in type positions and other reference-preserving positions. +4. **Preserve source pure references materialized only for resolution.** If a Source Document provided a pure reference and the provider materialized it only to resolve or validate content, the Canonical Identity Input MUST prefer the original pure reference form unless the instance supplied an overlay that must be represented. +5. **Consume overlay controls.** `$pos`, `$replace`, `$previous`, source list `null`, and empty-object list elements MUST NOT appear in Canonical Identity Input. Their effects must be represented as ordinary canonical content. +6. **No authoring aliases.** Type aliases and `blue` preprocessing directives MUST NOT appear in Canonical Identity Input. +7. **Deterministic map ordering.** When serializing helper maps or canonical JSON, property order is the order defined by RFC 8785 canonical JSON. No locale-sensitive ordering, implementation insertion order, or host map order is permitted. +8. **Smallest semantic identity input wins.** If two candidate identity inputs both satisfy the rules above, the one with fewer non-derivable fields and fewer materialized subtrees wins. If still tied, the RFC 8785 canonical JSON byte sequence of the candidate identity input is compared lexicographically and the smaller byte sequence wins. + +These rules are part of the Blue Language 1.0 identity definition and MUST be implemented consistently. The conformance fixture suite provides examples but does not replace these rules. + +### 13.6 Canonical list rules (normative) + +Canonical list rules produce final list payload content for identity calculation. + +For list payloads, final canonical list content is the canonical identity form. This rule overrides the general "omit derivable content" tie-breaker in §13.5.1. Blue Language 1.0 does not define a canonical list-diff representation. + +For a list with no inherited prefix, the Canonical Identity Input contains the canonicalized full list. + +For an inherited list under `mergePolicy: append-only`, a Minimized Overlay MAY use a valid `$previous` anchor followed by appended elements. A Canonical Identity Input MUST NOT contain `$previous`. Canonicalization MUST produce the final canonical list payload before hashing. This requirement defines the canonical semantic content; it does not require an implementation to reread or rehash the inherited prefix. When the exact inherited-prefix BlueId is already established and verified, the implementation MAY continue the §14.7 fold from that BlueId and hash only the appended delta. That optimization is not part of the serialized Canonical Identity Input and does not change the resulting BlueId. + +For an inherited list under `mergePolicy: positional`, a Minimized Overlay MAY represent inherited-index refinements using `$pos` overlays. A Canonical Identity Input MUST NOT contain `$pos`. Canonicalization MUST apply all positional overlays and produce the final canonical list payload before hashing. + +A final canonical list payload in Canonical Identity Input is identity input, not an instruction to append to or refine an inherited list under ordinary Source overlay semantics. + +### 13.7 Deterministic collapse during minimization (normative) + +A Minimized Overlay MAY collapse a subtree to `{ blueId: X }` only when: + +1. the subtree's BlueId is known to be `X`; +2. provider verification has established that `X` identifies that content if the subtree came from a provider; +3. collapse at that path is deterministic under the implementation's declared minimization rules; +4. the collapsed overlay re-resolves to the same Resolved Form. + +A Canonical Identity Input MUST follow the deterministic canonicalization rules. Unless this specification explicitly requires collapse at a path, Canonical Identity Input MUST prefer the materialized canonical identity form. Optional collapse is an author-facing minimization feature, not a source of variation in the Source-derived BlueId. + +A Canonical Identity Input MUST NOT depend on implementation-local collapse preferences. + +--- + +## 14. BlueId Algorithm + +### 14.1 Hash function (normative) + +Let: + +```text +H(x) = Base58(SHA-256(RFC 8785 canonical JSON of x)) +``` + +BlueId is computed bottom-up over canonical BlueId Input using `H`. + +### 14.2 Context-sensitive cleaning and placeholder normalization (normative) + +Before hashing, implementations MUST normalize BlueId Input context-sensitively. + +#### Object-field cleaning + +For object fields: + +- remove fields whose value is `null`; +- remove fields whose value normalizes to an empty object `{}`; +- preserve fields whose value is an empty list `[]`; + +This removal is recursive and may cascade. + +#### List-element rules + +For list elements: + +- list elements MUST NOT be deleted merely because they are `null` or `{}`; +- in Source Documents, `null`, `{}`, and elements that recursively clean to empty objects MUST have been normalized to `$empty: true` before BlueId calculation; +- in BlueId Input, `null` and `{}` list elements are invalid; +- `[]` is preserved as an empty list element; +- `$empty: true` is preserved as placeholder content. + +This rule preserves list length, order, and positional meaning. + +In object-field context, an object that becomes empty after cleaning is omitted. In list-element context, a Source element that becomes empty after recursive cleaning is normalized to `$empty: true` before BlueId Input is produced. Direct BlueId Input MUST NOT contain raw empty-object list elements. + +#### Root normalization + +The root of BlueId Input is never omitted by cleaning. + +If the root is an empty object `{}`, its BlueId is `H({})`. + +If object-field cleaning causes the root object to become empty, the root remains `{}` and hashes as `H({})`. + +A root `null` value is not valid BlueId Input. Source Documents whose root is `null` MUST be rejected. Authors who intend an empty object document MUST write `{}`; authors who intend an empty list document MUST write `[]`. + +### 14.3 Canonical BlueId input normalization (normative) + +The BlueId algorithm hashes the abstract node model, not authoring syntax. + +Direct BlueId calculation does not run the full Source Document preprocessing pipeline. However, BlueId input normalization includes the mandatory primitive scalar inference needed to make bare scalar nodes identity-stable across conforming implementations. This inference is limited to the core primitive types listed below and does not apply aliases, imports, `blue` directives, or declared preprocessing transforms. + +Before hashing a Node value: + +- scalar sugar is normalized to scalar payload; +- list sugar is normalized to list payload; +- bare scalar payloads with no explicit type are assigned the corresponding core primitive type reference; +- integer values outside the safe JSON numeric integer range are represented as quoted canonical decimal text while retaining explicit `Integer` type (§2.4); +- finite `Double` values are converted to their canonical scalar representation; +- pure references are represented exactly as `{ blueId: X }`; +- `blue` is rejected; +- `$pos` is rejected; +- list `null` and empty-object elements are rejected unless already normalized to `$empty: true`. + +Primitive scalar inference for BlueId input normalization uses: + +| Parsed value kind | Inferred type | +|---|---| +| string | `Text` | +| integer numeric token with no decimal point or exponent, or explicitly typed canonical integer text | `Integer` | +| numeric token with a decimal point or exponent, or other non-integer finite number | `Double` | +| boolean | `Boolean` | + +A scalar payload with explicit type uses the explicit type, subject to resolution and validation. + +### 14.4 Scalars (normative) + +For BlueId calculation, every scalar payload node is normalized to a **typed scalar identity form** before hashing. If no explicit effective type is present, the inferred primitive type from §14.3 is inserted. Therefore an untyped Source scalar token `1` hashes as a scalar node with effective type `Integer`, while source tokens `1.0` and `1e0` hash as scalar nodes with effective type `Double`. The effective scalar type is part of identity. + +A bare scalar payload is represented as the canonical scalar value and, when converted to canonical BlueId input as a node, includes its inferred primitive type unless an explicit type is already present. + +Scalar values are encoded using RFC 8785 canonical JSON value rules after Blue scalar normalization. + +For `Integer`, implementations MUST preserve mathematical integer identity. Integer values outside the safe JSON numeric integer range MUST be encoded as canonical decimal text while retaining `type: Integer` in the canonical BlueId input (§2.4). + +For `Double`, only finite numbers are valid. `NaN`, `Infinity`, and `-Infinity` are invalid Blue scalar values. + +A `Double` value whose canonical JSON number renders as an integer-looking number, such as `1`, remains distinct from `Integer` because the canonical BlueId input retains `type: Double`. Numeric rendering alone does not determine scalar type after preprocessing. + +### 14.4.1 Payload normalization before hashing (normative) + +The BlueId algorithm hashes the abstract Blue node model, not raw JSON/YAML syntax. + +Before map hashing is applied, each node is classified as one of: + +1. pure reference; +2. scalar payload node; +3. list payload node; +4. object payload node; +5. metadata-bearing node. + +A node with a scalar payload and no retained metadata other than its effective scalar type and value hashes as the typed scalar identity form. "Payload-only scalar" does not mean hashing the raw JSON scalar alone; it means hashing the canonical Blue scalar node consisting of the effective primitive type reference and the canonical scalar value. If no explicit effective type is present, the inferred primitive type is inserted before hashing. + +A node with a list payload and no retained metadata other than the payload itself hashes as the list payload. + +Therefore these forms hash identically: + +```yaml +x: 1 +``` + +```yaml +x: + value: 1 +``` + +and these forms hash identically: + +```yaml +x: [a, b] +``` + +```yaml +x: + items: [a, b] +``` + +Thus these Source scalar tokens do not all have the same typed scalar identity unless an explicit type or schema says otherwise: + +```yaml +1 # effective type Integer, value 1 +1.0 # effective type Double, canonical numeric payload may render as 1 +1e0 # effective type Double, canonical numeric payload may render as 1 +``` + +`1.0` and `1e0` are equivalent Double values, but they are not equivalent to Integer `1` because the effective type differs. + +When a node has retained metadata such as `type`, `schema`, `name`, `description`, `itemType`, `mergePolicy`, or `contracts`, it hashes as a metadata-bearing map. In that case, `value` or `items` is the payload field of that metadata-bearing node and participates in map hashing as defined below. + +A node MUST NOT contain more than one payload kind. + +### 14.5 Map hashing (normative) + +Map hashing applies only after payload-only scalar and payload-only list nodes have been normalized as described above. + +If and only if a map is exactly: + +```json +{ "blueId": "" } +``` + +then its BlueId is ``. This is the pure reference short-circuit. + +A map containing `blueId` together with sibling fields is not a pure reference and MUST NOT appear in BlueId Input. + +Otherwise, build the helper map `M` conceptually. Its serialized property order is the order defined by RFC 8785 canonical JSON. Implementations MUST NOT use locale-sensitive collation or implementation insertion order. + +- for `name`, `description`, and `value`, inline their cleaned scalar values; +- for every other key `k` with value `v`, include: + +```json +"k": { "blueId": id(v) } +``` + +Then compute: + +```text +id(map) = H(M) +``` + +This rule ensures nested structure contributes through BlueId rather than through byte shape. It also makes materialized subtrees and pure references identity-equivalent when they have the same BlueId. + +### 14.6 Object fields with `null` (normative) + +Object fields with `null` values are omitted before map hashing: + +```yaml +a: null +b: 1 +``` + +normalizes as: + +```yaml +b: 1 +``` + +If recursive cleaning makes a child object empty, the child field is also omitted. Empty lists are preserved. + +### 14.7 List hashing (normative) + +Lists are hashed using a domain-separated streaming fold over element BlueIds. The fold is recursive over list prefixes: the identity after element `n` is calculated from the identity of the first `n-1` elements and the BlueId of element `n`. + +This section defines the exact algorithm. Implementations MUST hash the canonical helper objects shown below. They MUST NOT replace the helper objects with raw string concatenation of Base58 BlueIds or with an implementation-specific binary encoding. + +#### 14.7.1 Empty-list seed, fold step, and recursive prefix identity (normative) + +Define the empty-list seed: + +```text +L0 = id([]) = H({ "$list": "empty" }) +``` + +Define a fold step over two already established exact identities: + +```text +FOLD_LIST_ID(previousPrefixBlueId, elementBlueId) = + H({ + "$listCons": { + "prev": { "blueId": previousPrefixBlueId }, + "elem": { "blueId": elementBlueId } + } + }) +``` + +The helper object passed to `H` is serialized using RFC 8785. Its property order is therefore the RFC 8785 order, not the visual order of the pseudocode and not host-map insertion order. + +For a list: + +```text +[a1, a2, ..., an] +``` + +define each prefix identity recursively: + +```text +L0 = id([]) +L1 = FOLD_LIST_ID(L0, id(a1)) +L2 = FOLD_LIST_ID(L1, id(a2)) +... +Ln = FOLD_LIST_ID(Ln-1, id(an)) +``` + +Then: + +```text +id([a1, a2, ..., an]) = Ln +``` + +Equivalently: + +```text +id(prefix + [x]) = FOLD_LIST_ID(id(prefix), id(x)) +``` + +The value `Ln-1` is exactly the BlueId of the list prefix `[a1, ..., an-1]`; it is not a separate hidden list state. + +For each element, `id(ai)` is the element's BlueId after BlueId input normalization. If the element is a pure reference, the pure-reference short circuit supplies the referenced BlueId. If the same element is materialized and verifies to that BlueId, the fold input is identical. + +#### 14.7.2 Incremental append (normative) + +If both of the following are already established and valid: + +```text +P = id([a1, ..., an]) +X = id(x) +``` + +then the BlueId of the appended list is: + +```text +id([a1, ..., an, x]) = FOLD_LIST_ID(P, X) +``` + +The implementation does not need to materialize, enumerate, or rehash `a1, ..., an` merely to calculate the new list identity. It performs one additional list fold step after establishing the new element's BlueId. + +For `k` appended elements `b1, ..., bk`, the implementation performs `k` additional fold steps: + +```text +P0 = id(existingList) +P1 = FOLD_LIST_ID(P0, id(b1)) +P2 = FOLD_LIST_ID(P1, id(b2)) +... +Pk = FOLD_LIST_ID(Pk-1, id(bk)) +``` + +and `Pk` is the BlueId of the resulting list. + +This optimization is valid only when the prefix BlueId is already established and trusted as the exact identity of the prefix used by the operation. An implementation MUST NOT accept an arbitrary claimed prefix BlueId merely to avoid processing the prefix. A `$previous` anchor is one Source-level way to carry such a claim, but resolution MUST verify it under §11.7 before it may seed the fold. An implementation may also obtain the exact prefix identity from an admitted exact list node, a verified provider, or a previously established immutable processing state. + +The append property avoids rereading the old elements for identity calculation. It does not make calculation of the appended element's own BlueId free, and it does not eliminate the identity work required to rebuild a metadata-bearing list node or its changed ancestors (§14.7.5). + +#### 14.7.3 Replacement, insertion, and removal (normative) + +The list fold is prefix-dependent. Changing an element changes that prefix state and therefore changes every later fold state. + +For a replacement at zero-based index `i` in a list of length `n`: + +```text +[a0, ..., ai-1, ai, ai+1, ..., an-1] + -> +[a0, ..., ai-1, x, ai+1, ..., an-1] +``` + +an implementation may reuse the exact identity of the unchanged prefix: + +```text +Pi = id([a0, ..., ai-1]) +``` + +when that identity is available. It must then fold: + +```text +id(x), id(ai+1), ..., id(an-1) +``` + +to establish the new final list identity. Thus the required fold work is proportional to the suffix beginning at the first changed position, not necessarily to the complete list. + +Insertion and removal have the same property: every fold state at and after the first changed position must be recomputed. Appending is the special case in which the first changed position is after the existing final element, so none of the existing fold states must be recomputed. + +A final list BlueId alone does not reveal element BlueIds, intermediate prefix BlueIds, list length, or list contents. If those values are required for enumeration or arbitrary editing, they must be available from the materialized list, a provider, or other verified storage metadata. The BlueId algorithm defines identity; it is not a reversible list encoding. + +#### 14.7.4 Identity calculation versus physical storage (informative) + +The incremental append property places no required storage format on providers. + +A provider may store, for example: + +- the complete list node; +- a shallow list representation containing direct element BlueIds; +- chunks of element BlueIds; +- an append record containing the previous list BlueId and appended element BlueId; +- additional verified prefix-index metadata. + +Whatever representation is used, the logical list and its final BlueId must be the same. Physical storage, caches, prefix indexes, and batching are not Blue Language semantics. + +An implementation that retains only the final 32-byte digest cannot reconstruct the list from that digest. It must retain or obtain the content separately when content access is required. + +#### 14.7.5 Metadata-bearing list nodes (normative) + +The streaming fold establishes the identity of a list payload. A node that also carries list metadata hashes as a metadata-bearing map under §14.5. + +For example: + +```yaml +entries: + type: List + itemType: Timeline Entry + mergePolicy: append-only + items: + - A + - B + - C +``` + +is conceptually identified in two layers: + +```text +itemsBlueId = id([A, B, C]) + +entriesNodeBlueId = id({ + type: List, + itemType: Timeline Entry, + mergePolicy: append-only, + items: { blueId: itemsBlueId } +}) +``` + +The second line is conceptual notation for the map-hashing rule; the exact type and metadata values contribute through their BlueIds as specified by §14.5. + +Appending `D` may establish the new list-payload identity with one fold step: + +```text +newItemsBlueId = FOLD_LIST_ID(itemsBlueId, id(D)) +``` + +but the implementation must also establish the new identity of the metadata-bearing list node and every changed ancestor that contains it. It still does not need to materialize or rehash unchanged earlier elements merely to continue the list fold. + +#### 14.7.6 Worked calculation (informative) + +For: + +```yaml +- A +- B +- C +``` + +let: + +```text +AID = id(A) +BID = id(B) +CID = id(C) +``` + +Then: + +```text +L0 = H({ "$list": "empty" }) +L1 = FOLD_LIST_ID(L0, AID) = id([A]) +L2 = FOLD_LIST_ID(L1, BID) = id([A, B]) +L3 = FOLD_LIST_ID(L2, CID) = id([A, B, C]) +``` + +To append `D`, if `L3` and `DID = id(D)` are already established: + +```text +L4 = FOLD_LIST_ID(L3, DID) = id([A, B, C, D]) +``` + +Calculating `L4` does not require the contents of `A`, `B`, or `C`. It requires the exact previous-list BlueId `L3` and the exact new-element BlueId `DID`. + +The semantic properties of the algorithm are: + +- order is significant; +- multiplicity is preserved; +- lists are not flattened; +- `[A]` is distinct from `A`; +- `[]` is distinct from absent values and cleaned object fields; +- `[A, {$empty: true}, B]` is distinct from `[A, B]`; +- pure-reference and verified materialized elements contribute the same element BlueId; +- append identity calculation can continue from an established exact prefix BlueId; +- arbitrary edits require recomputation of the affected suffix. + +### 14.8 List control normalization before hashing (normative) + +For direct anchored BlueId Input: + +- `$previous` MAY appear only as the first item. +- If present and well-formed, `$previous.blueId` MAY seed the list fold. +- Anchor validity is a precondition of direct anchored BlueId Input. +- A Canonical Identity Input produced by the Source Document identity pipeline MUST NOT contain `$previous`. +- Implementations MAY use a verified prefix BlueId as an internal hashing optimization. + +`$pos` and `$replace` MUST NOT appear in BlueId Input. `$empty: true` remains content and hashes as a normal object element. + +Malformed list controls MUST be rejected. + +### 14.8.1 Canonical JSON examples (informative but behavior-defining through referenced rules) + +#### Large Integer scalar node + +An Integer outside the safe JSON numeric integer range is represented as quoted canonical decimal text with explicit Integer type. + +Canonical BlueId Input shape: + +```yaml +type: + blueId: +value: "9007199254740992" +``` + +Map hashing builds helper map `M` conceptually: + +```json +{ + "type": { "blueId": "" }, + "value": "9007199254740992" +} +``` + +The RFC 8785 canonical JSON byte sequence is the UTF-8 encoding of: + +```json +{"type":{"blueId":""},"value":"9007199254740992"} +``` + +#### Double negative zero + +`Double` values use finite IEEE 754 binary64 semantics. Negative zero and positive zero compare as the same numeric value. Under RFC 8785 canonical JSON, the numeric value canonicalizes as JSON number `0`. + +A Source token such as `-0.0` infers `Double` if no explicit type is provided, but the canonical scalar numeric payload is `0` and the effective `type: Double` preserves the fact that the node is a Double rather than an Integer. + +#### Integer-looking Double + +A Source token such as `1.0` or `1e0` infers `Double`. The canonical JSON representation of the numeric payload may render as `1`, but the effective `type: Double` remains part of canonical BlueId input. Therefore `1` as Integer and `1.0` as Double are distinct Blue values unless an explicit type or schema says otherwise. + +#### List fold helper map ordering + +The list fold step uses the exact object keys `$listCons`, `prev`, and `elem`: + +```json +{"$listCons":{"elem":{"blueId":""},"prev":{"blueId":""}}} +``` + +The example shows the RFC 8785 canonical JSON serialization for these keys. Implementations MUST NOT rely on insertion order or host map order. + +### 14.9 Storage rule (normative) + +A node MUST NOT store its own BlueId as authoritative content. + +Using `{ blueId: ... }` to reference other nodes is permitted and encouraged. A provider or envelope MAY store a node's BlueId out-of-band, but the self-BlueId MUST NOT be treated as part of the node's own content. + +### 14.10 Inputs containing `blue` (normative) + +BlueId Input MUST NOT contain `blue`. A direct hasher MUST reject such input. + +--- + +### 14.11 Identity locality and direct-container cost (normative) + +BlueId is transitive through direct child identities rather than transitive child bytes. Therefore establishing or verifying an object's identity requires its complete direct helper map and the BlueIds of its direct children, but not the bodies of those children. + +Consequences: + +- a large descendant behind one direct child BlueId does not need to be expanded to verify or rebuild its parent; +- changing one member of a direct object requires rebuilding that object's complete direct helper map; +- appending to a list may continue from a verified prior fold identity; +- replacing, inserting, or removing an early list element requires recomputing the affected suffix fold; +- one extremely wide flat object or positional list remains expensive under Language 1.0 even when represented by a pure reference. + +These costs are properties of the current identity algorithm, not of inline versus referenced representation. The inline and referenced forms of the same exact node require the same direct identity information for the same structural update. + +Language 1.0 does not define Merkle maps or random-access Merkle vectors. Applications needing logarithmic point updates or proofs SHOULD use bounded-fanout application structures. A future major Language version may standardize such collection identities. + +## 15. Circular Reference Sets + +### 15.1 Purpose + +Some authoring graphs contain direct cycles across documents, for example `Person` references `Dog` and `Dog` references `Person`. Blue supports a combined BlueId for a cyclic set, with stable per-document suffixes. + +### 15.2 ZERO_BLUEID sentinel (normative) + +During cyclic-set calculation, each direct cyclic reference is temporarily replaced with the **ZERO_BLUEID** sentinel: forty-four ASCII `0` characters. + +ZERO_BLUEID is a sentinel only. It MUST NOT appear in finalized BlueId Input. + +During cyclic-set calculation, ZERO_BLUEID and `this#` are permitted only in positions where a BlueId string is expected inside the temporary cyclic-set calculation input. + +They are not valid ordinary BlueId Input and MUST NOT appear in finalized provider-stored content. + +### 15.3 Cyclic-set input (normative) + +The input to the cyclic-set algorithm is a finite set of document roots plus explicit internal reference markers indicating which references point to documents within the set. + +The algorithm applies to a strongly connected cyclic set. Independent strongly connected components SHOULD be processed separately. + +A cyclic-set calculation input MUST contain at least one internal cyclic reference. A set with no internal cyclic references SHOULD be treated as ordinary independent documents rather than as a cyclic set. + +If two cyclic-set members have identical preliminary BlueIds, implementations MUST compare the RFC 8785 canonical JSON byte sequence of their preliminary BlueId input as a deterministic tie-breaker. + +If the tie remains equal, the cyclic-set input is invalid in Blue Language 1.0 unless the members contain an explicit identity-bearing disambiguator before preliminary hashing. Implementations MUST fail cyclic-set calculation with `CircularSetError` rather than assigning arbitrary positions. + +Blue Language 1.0 does not define graph-isomorphism rules for duplicate preliminary cyclic members. + +### 15.4 Cyclic-set algorithm (normative) + +Given a finite set of documents participating in a direct cycle: + +1. Temporarily replace each internal cyclic `blueId` reference with ZERO_BLUEID. +2. Calculate preliminary BlueIds for each document in isolation. +3. Sort documents lexicographically by preliminary BlueId, with the tie-breaking rule from §15.3. +4. Assign positions `#0` through `#(n-1)` according to that order. +5. Rewrite each internal cyclic reference as: + +```yaml +blueId: this# +``` + +where `` is the assigned position of the target document. + +6. Build a list: + +```text +L = [doc#0, doc#1, ..., doc#(n-1)] +``` + +with `this#` references in place. + +7. Compute: + +```text +MASTER = id(L) +``` + +8. The final BlueId of document `i` is: + +```text +MASTER#i +``` + +The **preliminary BlueId input** for each document is the document after replacing each direct internal cyclic `blueId` reference with ZERO_BLUEID and before rewriting those references to `this#`. + +`this#` is accepted only by the cyclic-set calculation API. It MUST NOT appear in stored provider content, ordinary BlueId Input, Source Documents outside explicit cyclic-set serialization, or Canonical Identity Input. + +During preliminary BlueId calculation with ZERO_BLUEID placeholders, a pure reference `{ blueId: ZERO_BLUEID }` is treated as a temporary pure reference whose identity contribution is the sentinel value for the purpose of preliminary ordering only. ZERO_BLUEID MUST NOT be returned as a finalized BlueId. + +During MASTER calculation, pure references `{ blueId: "this#" }` are treated as internal cyclic placeholders as defined by the cyclic-set algorithm, not as ordinary provider references. + +Cyclic-set identity flow: + +```text +authoring refs + | + v +replace internal refs with ZERO_BLUEID + | + v +preliminary ids -> sort -> assign #0..#(n-1) + | + v +rewrite internal refs to this#k + | + v +MASTER = id([doc#0, doc#1, ...]) + | + v +final ids = MASTER#0, MASTER#1, ... +``` + +### 15.5 BlueId grammar for cyclic sets (normative) + +A cyclic-set member BlueId has the form: + +```text +# +``` + +where `MASTER` is a plain BlueId and `index` is a non-negative decimal integer with no leading zeros, except for the single digit `0`. + +`this#` is an algorithm-internal placeholder. It is accepted only by an implementation API explicitly performing cyclic-set calculation over a declared finite cyclic set. It MUST be rejected by ordinary parsing, preprocessing, resolution, provider storage, expansion, canonicalization, and direct BlueId calculation outside that cyclic-set calculation API. + +### 15.6 Example (informative) + +```yaml +# Dog (#0 after sorting) +name: Dog +owner: + type: + blueId: this#1 +breed: + type: Text + +# Person (#1 after sorting) +name: Person +pet: + type: + blueId: this#0 +``` + +If `MASTER = 12345...`, then: + +```text +Dog = 12345...#0 +Person = 12345...#1 +``` + +--- + +## 16. Conformance Vectors + +The Blue Language 1.0 conformance suite, canonical core registry, and this prose specification jointly define Blue Language 1.0. The prose rules are normative, the registry supplies exact identity-bearing core type nodes and BlueIds, and the fixtures provide behavior-defining executable examples. + +A fixture package identity MUST be published with the Blue Language 1.0 release. A conforming implementation MUST report which fixture package identity it passes. + +If the prose specification, registry, and fixture package conflict, the release artifact is invalid and MUST be corrected. Implementations MUST NOT guess which artifact wins. + +Conformance vectors are behavior-defining. A conforming Blue Language 1.0 implementation MUST pass all vectors in this section and all machine-readable fixtures in the Blue Language 1.0 conformance suite. + +The labels `B`, `R`, and `F` identify fixture categories: BlueId algorithm, resolution/canonicalization, and provider/full-graph behavior. They do not define separate conformance levels. + +### 16.1 BlueId algorithm vectors + +- **B1.** `id([])` is defined and distinct from absent values and cleaned object fields. +- **B2.** `[A]` hashes differently from `A`. +- **B3.** `[[A, B], C]` hashes differently from `[A, B, C]`. +- **B4.** `x: 1` and `x: { value: 1 }` produce the same BlueId after canonical input normalization. +- **B5.** `x: [a, b]` and `x: { items: [a, b] }` produce the same BlueId. +- **B6.** A map exactly `{ blueId: X }` hashes to `X`. +- **B7.** Object-field cleaning removes `null` fields and fields that normalize to empty objects. +- **B8.** Cleaning preserves `[]`. +- **B9.** A node containing `blue` is rejected as direct BlueId Input. +- **B10.** A map mixing `blueId` with sibling fields is rejected as BlueId Input. +- **B11.** Primitive scalar inference assigns `Text`, `Integer`, `Double`, and `Boolean` deterministically. +- **B12.** `$empty: true` remains content and affects BlueId. +- **B13.** Direct BlueId Input containing a `null` list element is rejected. +- **B14.** Direct BlueId Input containing an empty-object list element is rejected unless it has already been normalized to `$empty: true` before direct hashing. +- **B15.** `[A, {$empty: true}, B]` hashes differently from `[A, B]`. +- **B16.** Integer values above `9007199254740991` or below `-9007199254740991` are represented as quoted canonical decimal text with explicit `Integer` type. +- **B17.** `this#` is rejected outside the explicit cyclic-set calculation API. +- **B18.** A source numeric token `1` infers `Integer`; source numeric tokens `1.0` and `1e0` infer `Double`; explicit `type: Double` remains Double even when the canonical JSON number renders as `1`. +- **B19.** Root `{}` is valid BlueId Input and hashes as an empty object; it is not omitted. +- **B20.** Root `null` is invalid as Source Document root and as BlueId Input. +- **B21.** Plain BlueIds validate as canonical Base58 encodings of exactly 32 bytes; invalid alphabet characters, non-canonical encodings, wrong decoded length, and plain ID strings containing `#` are rejected. +- **B22.** `$empty` list placeholder shape is exactly `{ "$empty": true }`; malformed `$empty` items are rejected. +- **B23.** `Double` negative zero canonicalizes to numeric payload `0` while retaining Double type. +- **B24.** `Double` overflow is rejected. +- **B25.** Integer-looking Double canonical rendering retains Double type. +- **B26.** Payload-only scalar hashing uses typed scalar identity form, not raw JSON scalar hashing. +- **B27.** Enum order and duplicate entries do not affect effective canonical schema identity. +- **B28.** `Double` `multipleOf` is evaluated by exact rational arithmetic over IEEE 754 binary64 values. +- **B29.** A cyclic-set input with duplicate preliminary member inputs fails unless the members contain identity-bearing disambiguators before preliminary hashing. +- **B30.** A fully materialized node and its direct-node materialization pattern have the same BlueId. +- **B31.** Replacing a direct child by a pure reference to that child preserves the parent BlueId. + +### 16.2 Resolution and canonicalization vectors + +- **R1.** Preprocessing removes `blue` and applies baseline transforms before resolution. +- **R2.** Source list `[A, null, B]` preprocesses to `[A, {$empty: true}, B]`, not `[A, B]`. +- **R3.** Source list `[A, {}, B]` preprocesses to `[A, {$empty: true}, B]`, not `[A, B]`. +- **R4.** Type chains merge according to the overlay and subtyping rules. +- **R5.** Fixed-value invariants cannot be overridden. +- **R6.** Schema constraints accumulate; irreconcilable constraints fail resolution. +- **R7.** Schema objects containing keys outside §9.2 are rejected. +- **R8.** `name` and `description` are ignored by matchers and subtype checks. +- **R9.** Type root `name` and `description` are not inherited onto the instance root. +- **R10.** A Source Document and its Resolved Form, after canonicalization, derive the same BlueId. +- **R11.** Requirement overlays bind valid type completions and reject conflicting completions. +- **R12.** `$previous` is validated against the resolved inherited prefix; mismatch fails resolution. +- **R13.** `mergePolicy` defaults to `positional` only when there is no inherited effective `mergePolicy`. +- **R14.** Append-only lists reject `$pos`. +- **R15.** Positional lists reject inherited-prefix reordering and removal. +- **R16.** A Minimized Overlay re-resolves to the same Resolved Form. +- **R17.** Canonical Identity Input does not contain `$previous`, `$pos`, `blue`, unresolved aliases, `null` list elements, or empty-object list elements. +- **R18.** Direct hashing of a Resolved Form is not used as the Source Document's BlueId unless the Resolved Form is already identical to its Canonical Identity Input. +- **R19.** Canonical Identity Input for append-only lists does not serialize `$previous`; `$previous` may appear only in Minimized Overlay or direct anchored BlueId Input. +- **R20.** Canonical Identity Input contains no type aliases; all type references are canonical BlueId references. +- **R21.** A source pure reference that is materialized only for resolution canonicalizes back to the pure reference unless the source overlays additional instance content onto it. +- **R22.** A child overlay of an inherited `append-only` list that omits `mergePolicy` remains `append-only`; `$pos` is still rejected. +- **R23.** A descendant collection that omits inherited `itemType`, `keyType`, or `valueType` retains the inherited constraint. +- **R24.** Canonical positional list refinements produce final canonical list payloads, not Source overlay instructions. +- **R25.** Minimized positional list overlays may use `$pos` and re-resolve to the same Resolved Form. +- **R26.** Canonical append-only list overlays do not contain `$previous`; minimized append-only overlays may use `$previous`. +- **R27.** Inherited effective Integer type accepts quoted canonical large decimal text. +- **R28.** Quoted decimal text without effective Integer type remains Text. +- **R29.** Inherited effective Integer type rejects non-canonical decimal text. +- **R30.** Declaration-only label overrides are allowed, but label overrides on inherited fixed-value nodes are rejected. +- **R31.** Type-chain cycles and self-type cycles are rejected. +- **R32.** Required metadata-only fields fail, while required instance payloads and inherited fixed payloads pass. +- **R33.** `minFields` and `maxFields` count ordinary fields only. +- **R34.** Wrong-kind schema keywords fail schema validation. +- **R35.** `itemType`, `keyType`, and `valueType` validate resolved collection members. +- **R36.** Direct Dictionary integer keys use canonical textual form and reject duplicate key conflicts after canonicalization. +- **R37.** Source list `[A, { x: null }, B]` preprocesses to `[A, { $empty: true }, B]`. +- **R38.** Canonical core type compatibility is nominal by registry BlueId. +- **R39.** Blue Language operation path root is the empty string under RFC 6901; `/` selects the empty-key member. +- **R40.** Limited resolution of a demanded path yields the same value, effective type, and applicable constraints as complete resolution. +- **R41.** A limited resolver never reports an unexpanded or unresolved field as absent merely because a limit prevented access. +- **R42.** An incomplete limited result is rejected as input to whole-node canonicalization, Source Document BlueId calculation, and minimization. +- **R43.** A limit, unexpanded reference, or unavailable provider resource never produces a successful `Absent` result. +- **R44.** Semantic lookup through a pure reference is transparent: a collapsed wrapper does not create a semantic child named `blueId`. +- **R45.** A demand-limited exact-node-identity request returns the same BlueId for inline, collapsed, and partially expanded forms. +- **R46.** A pure reference used as `schema` or `contracts` is semantically equivalent to its verified materialization; operations expand it only when its contents are demanded. +- **R47.** A source pure reference used for `schema` or `contracts`, when materialized only for resolution or validation, is preserved as the source pure reference by canonicalization unless a non-derivable instance overlay must be represented. +- **R48.** Omitting `blue` still applies the complete mandatory baseline preprocessing algorithm. +- **R49.** An empty inline `blue` directive and an omitted directive produce the same Preprocessed Document. +- **R50.** An inline preprocessing directive and a pure reference to that exact directive produce the same Preprocessed Document. +- **R51.** A referenced directive, imports object, transformations list, or transformation item is used only after exact provider verification; invalid evidence fails. +- **R52.** Declared transformations execute exactly once each in declared list order, and each transformation receives the prior transformation's complete output. +- **R53.** Transformations execute before automatic alias substitution and primitive inference; mandatory baseline preprocessing normalizes transformation output afterward. +- **R54.** When one directive contains both `imports` and `transformations`, the import map is established before execution, transformations execute first, and remaining aliases are substituted afterward. +- **R55.** `blue.imports` substitutes aliases only in `type`, `itemType`, `keyType`, and `valueType` positions; identical ordinary Text values remain data. +- **R56.** A transformation item may be inline or a verified pure reference without changing the preprocessing result. +- **R57.** `imports` and `transformations` may themselves be verified reference-backed exact nodes. +- **R58.** An unsupported required transformation causes deterministic `UnsupportedPreprocessingTransform` failure and is never ignored. +- **R59.** A transformation that introduces `blue` at any path fails preprocessing. +- **R60.** A string-valued directive alias resolves to one exact directive BlueId under the declared preprocessing environment; an unbound alias fails. +- **R61.** A built-in alias may be repeated only with its canonical BlueId; rebinding it to a different BlueId fails. +- **R62.** `blue` is valid only at the Source Document root; nested directives fail. +- **R63.** Preprocessing is idempotent for an already valid Preprocessed Document. +- **R64.** An unused import does not change the Preprocessed Document or Source-derived BlueId. +- **R65.** Blue Language 1.0 defines no `blue.profile` wrapper; reusable directives use `blue: { blueId: X }` directly. +- **R66.** The portable transformation list is declared by `blue.transformations`; a legacy `blue.items` list-payload directive is invalid. +- **R67.** A portable transformation's type must be exact and cannot depend on Source-document import alias substitution. +- **R68.** Expansion of a verified existing node preserves that node's BlueId, while specialization through `type` and compatible overlay content creates a new node and normally a different BlueId. +- **R69.** The Source Document identity pipeline is `preprocess -> complete resolve -> canonicalize -> BlueId`; minimization is not a step in that pipeline. +- **R70.** The BlueId derived from a Source Document is exactly the BlueId of its unique Canonical Identity Input. +- **R71.** Directly hashing a Source Document, noncanonical Resolved Form, or Minimized Overlay MUST NOT be assumed to produce the Source Document's BlueId. +- **R72.** For an inherited append-only list, canonicalization produces the final ordinary list payload, while minimization may use a valid `$previous` overlay; both derive the same BlueId only through the complete Source Document identity pipeline. +- **R73.** For an inherited positional list, canonicalization produces the final ordinary list payload, while minimization may use `$pos` or `$replace`; both derive the same BlueId only through the complete Source Document identity pipeline. + +### 16.3 Provider, expansion, and collapse vectors + +- **F1.** All B-vectors and R-vectors pass. +- **F2.** Expansion preserves BlueId. +- **F3.** If the implementation exposes collapse, collapse preserves BlueId and produces only valid pure references. +- **F4.** Expansion supports configurable depth or path limits that do not affect identity. +- **F4a.** A document root supplied as `{ blueId: X }` can be expanded only at demanded paths without recursively materializing all descendants. +- **F4b.** Inline and verified referenced forms produce identical demanded expansion and resolution results. +- **F5.** Cross-document references resolve through a provider without changing identity. +- **F6.** Missing provider content required for resolution fails deterministically. +- **F7.** Ordinary BlueId provider content whose computed BlueId does not equal the requested BlueId is rejected. +- **F8.** Source Document provider content requires a declared Source Document provider mode and Source Document BlueId verification. +- **F9.** Cyclic-set member provider content requires cyclic-set-aware verification context. +- **F16.** An exact direct-fragment graph reconstructs the original Root and preserves every Root BlueId. +- **F17.** Fragment identity order and provider results are deterministic and defensive. +- **F18.** A finalized `MASTER#index` edge is preserved opaquely; the ordinary fragment provider does not claim member content. +- **F19.** A cyclic-aware provider can open an opaque member only with complete owning-set proof. +- **F10.** One materialized object node can be verified from its complete direct keys, inline identity scalars, and child BlueIds without fetching child bodies. +- **F11.** One materialized list node can be verified from its ordered element BlueIds without fetching element bodies. +- **F11a.** Provider-internal append anchors or prefix folds do not replace the complete ordered direct element identities needed to reconstruct a requested direct list node. +- **F12.** Expanding one node while leaving complete direct children collapsed, and then collapsing the selected node again, preserves the exact root BlueId and does not demand descendant bodies that were never selected. +- **F13.** Demanding `/a/b/c` from a direct-node provider requires only the root and the direct nodes on that path, unless type or schema semantics demand additional nodes. +- **F14.** Provider batching, prefetching, and cache state do not change semantic results. +- **F15.** A provider that omits a demanded direct key cannot report absence unless the complete direct manifest has been verified. + +### 16.4 Machine-readable fixtures (normative) + +The Blue Language 1.0 conformance suite MUST publish machine-readable fixtures with exact expected BlueIds. + +The canonical fixture package is part of the Blue Language 1.0 conformance release and is versioned with this specification.

Exact expected BlueIds are defined by the machine-readable fixture suite (§16.4). + +### 17.1 Content-addressable types (informative) + +```yaml +name: Simple Amount +amount: + type: Double +currency: + type: Text +# => blueId: FgHZjS... + +name: Person +age: + type: Integer +spent: + type: + blueId: FgHZjS... # Simple Amount +# => blueId: GRwTYs... +``` + +Instance: + +```yaml +name: Alice +type: + blueId: GRwTYs... # Person +age: 25 +spent: + amount: 27.15 + currency: USD +# => Source-derived BlueId: 3JTd8s... +``` + +Expanding the demanded type links makes the existing type nodes available without changing their BlueIds. The instance itself is a specialization: it uses `Person` as its type and supplies more specific content, so it is a new node. Resolving produces the complete semantic values. Complete resolution followed by canonicalization produces a Canonical Identity Input whose BlueId is the Source-derived BlueId of the instance. + +### 17.2 `blue` directive (informative) + +A document may declare imports and ordered transformations inline: + +```yaml +blue: + imports: + Ticket: + blueId: + DateTime: + blueId: + transformations: + - type: + blueId: + mappings: + Ticket Serial No.: ticketSerial + Departure: departure + - type: + blueId: + path: /departure + pattern: yyyy-MM-dd HH:mm + +type: Ticket +Ticket Serial No.: HL-923554 +Departure: 2025-03-27 15:25 +``` + +The processor first resolves and verifies the directive, imports, and transformation nodes. It removes `blue`, applies the rename transformation, then applies the DateTime transformation. Only after both transformations finish does mandatory baseline preprocessing replace `Ticket` and `DateTime` aliases, normalize wrappers and placeholders, and infer types for bare primitive values. + +The same complete directive can be stored as an exact Blue node and collapsed in the Source Document: + +```yaml +blue: + blueId: + +type: Ticket +Ticket Serial No.: HL-923554 +Departure: 2025-03-27 15:25 +``` + +When the referenced directive verifies to the inline directive above, both Source Documents preprocess identically. Blue Language 1.0 defines no separate `blue.profile` wrapper. + +### 17.3 Large integer (informative) + +```yaml +accountId: + type: Integer + value: "9007199254740992" +``` + +The value is quoted because it is outside the safe JSON numeric integer range. The explicit `Integer` type distinguishes it from Text. + +Numeric token inference: + +```yaml +a: 1 # inferred Integer +b: 1.0 # inferred Double +c: 1e0 # inferred Double +d: + type: Double + value: 1 +``` + +`b`, `c`, and `d` are Double values even when their canonical JSON number renders as `1`. + +### 17.4 Same image, different meaning (informative) + +```yaml +# A +name: Person to Avoid +description: This guy will kill you today +type: Image +image: + blueId: 123...456 + +# B +name: Family Member +description: Trust this person +type: Image +image: + blueId: 123...456 +``` + +These derive different BlueIds because `name` and `description` are identity content. Structural and type matchers ignore those labels. + +### 17.5 Requirement overlay followed by type binding (informative) + +```yaml +# Parent +name: A +prop1: + x: 1 + +# Child +name: B +type: A +prop1: + type: Some +``` + +The child is valid only if `Some` can resolve while preserving `x = 1`. If `Some` forces `x = 2`, resolution fails. + +### 17.6 Lists: refine and append (informative) + +```yaml +# Parent +name: Trip +segments: + type: List + itemType: Flight Segment + items: + - type: Flight Segment + carrier: BA + +# Child +name: Trip LHR to SFO +type: Trip +segments: + items: + - $pos: 0 + from: LHR + to: JFK + - type: Flight Segment + carrier: BA + from: JFK + to: SFO +``` + +The child refines inherited index `0` and appends a second segment. Reordering or deleting the inherited prefix would be invalid. + +### 17.7 Null list element as placeholder (informative) + +```yaml +items: + - A + - null + - B +``` + +preprocesses to: + +```yaml +items: + - A + - $empty: true + - B +``` + +It does not preprocess to `[A, B]`. + +### 17.8 Expansion with limits (informative) + +Starting from: + +```yaml +blueId: 3JTd8s... # Alice +``` + +expanding `/spent` may hydrate only the `spent` subtree: + +```yaml +name: Alice +type: + blueId: GRwTYs... +age: 25 +spent: + amount: 27.15 + currency: USD +``` + +BlueId is unchanged if the hydrated content verifies to the referenced BlueIds. + +### 17.9 Canonicalization and minimization (informative) + +From a complete Resolved Form with the type content required for identity, canonicalization: + +- represents type objects by exact references where required; +- removes structure fully derivable from the type chain; +- consumes `$pos`, `$replace`, and `$previous` controls; +- normalizes list placeholders to `$empty: true`; +- keeps non-derivable instance contributions; +- produces one valid BlueId Input. + +Consider an inherited append-only list `[A, B]` with `C` appended. A Minimized Overlay may say only: + +```yaml +items: + - $previous: + blueId: + - C +``` + +The Canonical Identity Input contains the final payload: + +```yaml +items: + - A + - B + - C +``` + +The first is convenient authoring compression. The second is the unique identity input. The Source-derived BlueId is calculated from the second. The minimized form reaches the same BlueId only after it is processed through preprocessing, complete resolution, canonicalization, and the BlueId algorithm again. + +### 17.10 Contracts merge as content (informative) + +```yaml +# Parent type +name: With Audit +contracts: + audit: + type: Audit Contract + enabled: true + +# Child instance +type: With Audit +contracts: + audit: + retentionDays: 30 +``` + +Language resolution merges `contracts.audit` as content. It does not execute the contract. The resolved contract entry contains both `enabled: true` and `retentionDays: 30`, unless normal fixed-value, type, or schema rules reject the merge. + +### 17.11 Incremental list BlueId calculation (informative) + +Blue list identity is a hash chain over exact element BlueIds. + +For the list: + +```yaml +items: + - A + - B + - C +``` + +the processor calculates: + +```text +L0 = id([]) +L1 = fold(L0, id(A)) = id([A]) +L2 = fold(L1, id(B)) = id([A, B]) +L3 = fold(L2, id(C)) = id([A, B, C]) +``` + +If `D` is appended and `L3` is already known: + +```text +L4 = fold(L3, id(D)) = id([A, B, C, D]) +``` + +The existing elements do not need to be expanded or rehashed for that append. By contrast, replacing `B` requires a new `L2` and then a new `L3`; every fold step after the first changed position is recalculated. + +For the exact domain-separated helper objects and the distinction between payload identity, metadata-bearing list-node identity, and storage, see §14.7. + +### 17.12 Common invalid forms (informative) + +Mixed reference and content is invalid: + +```yaml +blueId: X +name: Not allowed +``` + +`blue` is root-only and preprocessing-only: + +```yaml +child: + blue: something +``` + +`$pos` cannot appear in Canonical Identity Input or BlueId Input: + +```yaml +items: + - $pos: 0 + value: A +``` + +Use `$replace` for non-scalar positional replacement: + +```yaml +# Invalid +- $pos: 0 + value: + items: [A, B] + +# Valid +- $pos: 0 + $replace: + items: [A, B] +``` + +--- + +## Appendix A — Core Primitive and Collection Types + +Appendix A defines the canonical primitive and collection types referenced throughout this specification. + +The nodes in §A.1 are canonical type definitions, not illustrative sketches. Their `description` fields are normative, identity-bearing Blue content. The exact registry files used to calculate published BlueIds MUST be byte/string equivalent after Blue parsing to the intended canonical nodes. + +The core registry nodes in this appendix are the canonical Blue Language 1.0 primitive and collection definitions. Their `1.0` wording is identity-bearing content and agrees with this first public-version specification. The exact registry files—not retyped copies in implementation code—are authoritative for their published BlueIds. + +The execution environment selects Blue Language 1.0; the exact core-type BlueIds select the primitive meanings. After publication, an existing core-type BlueId may receive only errata outside the node. Changing identity-bearing semantics requires a new type identity. + +Changing a canonical node's `description` is a type-identity change. Implementations MUST NOT silently update canonical descriptions while keeping the old BlueId. + +If a typo or editorial issue is found after publication and it does not change semantics, publish errata outside the canonical node. If the text change is intended to alter or clarify the type's meaning in an identity-bearing way, publish a new registry entry with a new BlueId. + +### A.1 Canonical core type nodes + +#### Text + +```yaml +name: Text +description: > + Core Blue Language 1.0 primitive scalar representing Unicode text. Text + values are exact Unicode code-point sequences after parsing. Blue Language + performs no Unicode normalization, case folding, locale-sensitive collation, + whitespace normalization, or line-ending normalization by default. String + schema constraints minLength and maxLength count Unicode code points. The + empty string is valid unless restricted by schema. Applicable schema + constraints are minLength, maxLength, and enum. +``` + +#### Integer + +```yaml +name: Integer +description: > + Core Blue Language 1.0 primitive scalar for exact mathematical integer + values. Integer values are arbitrary precision in the language model. + Unquoted integer tokens are portable only in the safe JSON numeric integer + range [-9007199254740991, 9007199254740991]. Integer values outside that + range are represented as quoted canonical decimal text with explicit or + inherited effective Integer type. The canonical decimal text form uses an + optional leading minus sign followed by decimal digits, with no leading + zeros except the single digit zero. Applicable schema constraints are + minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, and enum. +``` + +#### Double + +```yaml +name: Double +description: > + Core Blue Language 1.0 primitive scalar for finite IEEE 754 binary64 + floating-point values. NaN, positive Infinity, and negative Infinity are + invalid Blue values. Double parsing uses round-to-nearest, ties-to-even + binary64 semantics; numeric tokens that overflow to Infinity or parse as NaN + are invalid. Source numeric tokens with a decimal point or exponent infer + Double when no explicit type is provided, even when their mathematical value + is integral. Negative zero and positive zero compare as the same numeric + value and canonicalize as JSON number zero, while the effective Double type + remains part of canonical BlueId input. Applicable schema constraints are + minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, and enum. +``` + +#### Boolean + +```yaml +name: Boolean +description: > + Core Blue Language 1.0 primitive scalar with exactly two values: true and + false. Blue Language defines no truthiness conversion for Boolean values. + Only the literal parsed boolean values true and false are Boolean values. + Applicable schema constraint is enum. +``` + +#### Dictionary + +```yaml +name: Dictionary +description: > + Core Blue Language 1.0 object-map collection type. A Dictionary is encoded + as a Blue object node whose ordinary child fields represent direct keys + when those keys do not collide with reserved language fields. Direct object + encoding cannot represent data keys named name, description, type, itemType, + keyType, valueType, value, items, blueId, blue, schema, mergePolicy, + contracts, properties, or constraints. Direct object encoding cannot + represent reserved language keys as data keys. Applications needing + arbitrary keys use an escaped entry representation such as a list of { key, + val } entries. keyType is optional; if + omitted and no effective keyType is inherited, keys default to Text for + direct object encoding. For direct object encoding, keyType must resolve to + a scalar key type with a canonical textual form, such as Text, Integer, + Double, or Boolean. valueType is optional; if omitted and no effective + valueType is inherited, values may be any Blue node. Applicable schema + constraints are minFields and maxFields. +``` + +#### List + +```yaml +name: List +description: > + Core Blue Language 1.0 ordered collection type. Surface array form and + wrapped items form are equivalent authoring forms. Order and multiplicity + are preserved. List BlueId calculation uses a domain-separated streaming + fold over element BlueIds. itemType is optional; if omitted and no effective + itemType is inherited, elements are not constrained by itemType. If + mergePolicy is omitted and no effective mergePolicy is inherited, resolvers + assume positional. append-only forbids changes to the inherited prefix. + positional allows $pos overlays within the inherited prefix. $previous, + $pos, $replace, and $empty are recognized only at the top level of items + when the node's effective type is List. Source list null and empty object + elements normalize to $empty: true and are not deleted. Applicable schema + constraints are minItems, maxItems, and uniqueItems. +``` + +### A.2 Editorial and registry rules + +The canonical registry nodes above are the Blue Language 1.0 core type nodes, retaining their established exact content and BlueIds. Their registry manifest is published under the Language 1.0 release and MUST be fixture-verified together with this specification. Non-normative examples, tutorials, rationale, translations, and implementation notes are not part of the canonical type nodes unless intentionally included in the registry entries. + +Additional explanatory documentation MAY follow this appendix or appear in separate registry documentation, but it MUST be clearly marked non-canonical unless it is included in the registry node itself. + +--- + +## Appendix B — Reserved Extension Boundary + +`contracts` is reserved for the Blue Contracts and Processor Specification 1.0. Blue Language 1.0 treats it as identity-bearing content only. See §4.4. + +--- + +## Appendix C — Common Implementer Mistakes + +This appendix is informative. + +### C.1 Do not delete list positions + +`[A, null, B]` does not mean `[A, B]`. Source list `null` and `{}` elements normalize to `$empty: true`. + +### C.2 Do not hash `blue` + +`blue` is a preprocessing directive. Direct BlueId input containing `blue` must be rejected. + +### C.3 Do not treat `value` as a generic replacement field + +`value` is the scalar payload wrapper. Positional non-scalar replacement uses `$replace`. + +### C.4 Do not let `$pos` reach BlueId input + +`$pos` is an overlay instruction. Canonical Identity Input and direct BlueId Input must not contain `$pos`. + +### C.5 Do not trust provider content without verification + +When expanding `blueId: X` through an ordinary BlueId provider, compute the returned content's BlueId and verify that it equals `X`. + +### C.6 Do not treat `name` and `description` as comments + +They affect BlueId. They are ignored by matchers, not by identity. + +### C.7 Use only the schema keywords defined in §9 + +A `schema` object accepts only the keywords listed in §9.2. + +### C.8 Do not use reserved language keys as ordinary object fields + +Reserved keys such as `type`, `value`, `items`, and `schema` have language meaning. + +--- + +### C.9 Do not expose the pure-reference wrapper as semantic content + +A semantic graph lookup must treat `{ blueId: X }` as node `X`, not as an application object containing a data field named `blueId`. + +### C.10 Do not let physical representation change semantic results + +Cache hits, provider pages, network bytes, batching, and host allocations are not Blue content. They must not change a Language operation's established, absent, incomplete, or invalid outcome. + +### C.11 Do not confuse expansion with specialization + +Expansion reveals more of an existing exact node and preserves its BlueId. Specialization creates a new node through `type` and compatible overlay content and normally creates a new BlueId. + +### C.12 Do not minimize before hashing + +Minimization is optional authoring compression. A Source Document's BlueId is calculated by complete resolution, canonicalization, and the BlueId algorithm. Directly hashing a Minimized Overlay does not establish that Source-derived BlueId. + +### C.13 Do not confuse semantic canonicalization with JSON serialization + +Blue semantic canonicalization derives the Canonical Identity Input. RFC 8785 canonical JSON is used later inside the BlueId algorithm. JSON key sorting alone is not Blue semantic canonicalization. + +### C.14 Do not require transitive expansion to verify a direct node + +The existing map and list BlueId algorithms verify one direct node from direct child identities. Fetching all descendants is unnecessary. + +### C.15 Do not confuse incremental list identity with reversible storage + +Appending to an exact list can calculate the new BlueId from the previous list BlueId and the appended element BlueId. This does not mean the final BlueId contains or can reconstruct the previous elements. Providers must retain or obtain list content separately when enumeration or arbitrary editing is required. Replacing, inserting, or removing an earlier element requires recomputing the affected fold suffix. + +## Appendix D — Error Categories + +This appendix is normative for conformance diagnostics but does not require a particular exception class, wire format, or exact error message. + +When an operation fails deterministically, implementations MUST be able to classify the failure into one of these categories for conformance reporting: + +| Category | Meaning | +|---|---| +| `InvalidSyntax` | Serialized JSON/YAML is malformed or outside the Blue JSON data model. | +| `DuplicateKey` | A serialized object contains duplicate keys. | +| `InvalidReservedField` | A reserved field has an invalid type, shape, or position. | +| `InvalidBlueId` | A BlueId string is malformed or invalid for its context. | +| `InvalidReferenceShape` | `blueId` appears with sibling fields or invalid mixed reference shape. | +| `InvalidBlueIdInput` | Direct BlueId received a node that is not valid BlueId Input. | +| `ProviderUnavailable` | Required provider content is unavailable. | +| `ProviderBlueIdMismatch` | Provider content does not verify against the requested BlueId. | +| `OperationIncomplete` | A demanded semantic result could not be established because required content or coverage was not available. | +| `OperationLimitExceeded` | An out-of-band operation limit prevented completion of a demanded result. | +| `TypeCycle` | Resolution detected a type-cycle in the active type stack. | +| `FixedValueConflict` | A descendant attempted to override or contradict an inherited fixed value. | +| `TypeCompatibilityViolation` | A descendant type, itemType, keyType, or valueType is incompatible with an inherited constraint. | +| `SchemaVocabularyError` | A schema contains an unknown keyword or invalid schema value shape. | +| `SchemaViolation` | A node violates accumulated schema constraints. | +| `ListControlViolation` | `$previous`, `$pos`, `$replace`, or `$empty` has invalid shape or context. | +| `CanonicalizationError` | A Canonical Identity Input cannot be produced deterministically. | +| `CircularSetError` | Cyclic-set input is malformed or cannot produce deterministic member IDs. | +| `UnsupportedPreprocessingTransform` | A Source Document requires a preprocessing transform that is unsupported. | + +An invalid document may contain multiple independent errors. Blue Language 1.0 does not require a universal precedence order for all possible simultaneous failures. Conformance fixtures that assert an exact error category MUST isolate one primary error so that a conforming implementation can deterministically report that category without ambiguity. If a fixture intentionally contains multiple independent errors, it MUST assert only that the operation fails, or it MUST explicitly declare acceptable error categories. + +--- + +## Appendix E — Informative Direct-Node Storage Guidance + +This appendix is informative. It does not add a separate Language conformance mode. + +### E.1 Admission + +A provider optimized for lazy graph access may normalize and verify a node, establish every direct child BlueId, and store one direct-node representation whose complete children are collapsed, keyed by the node's own BlueId. + +### E.2 Retrieval + +Retrieval of one BlueId should return enough direct content to verify that exact node without requiring descendant bodies. A provider may batch additional verified nodes, but batching is prefetch rather than semantics. + +### E.3 Path navigation + +A caller can verify the current direct node, select the direct child identity for the next path segment, fetch that child, and repeat. Type resolution or schema validation may demand additional nodes beyond the structural path. + +### E.4 Direct-node limitation + +A directly materialized node still contains its complete direct manifest and inline identity-bearing text. Very wide containers and very large direct scalars therefore remain unsuitable as fine-grained mutable structures. Chunking is the recommended Language 1.0 authoring pattern. + +### E.5 Provider chains + +Provider implementations should distinguish definitive `NotFound`, transient `Unavailable`, and deterministic `InvalidEvidence`. None of these outcomes is semantic path absence without the Language operation proving absence from sufficient graph content. + +### E.6 Exact graph fragments + +An exact graph fragment is ordinary Blue content. A fragment materializes one exact node while replacing any complete direct child with a pure reference to that child's exact BlueId. It is not a partial-node identity, cursor language, or fifth Language operation. + +A portable fragment utility SHOULD: + +- accept one or more exact Root nodes; +- calculate and verify every admitted fragment identity; +- expose original, direct-fragment, and pure-reference Root forms; +- serve defensive copies through a verified provider; +- order fragment identities canonically; +- preserve all Language metadata, schema, list, and reference semantics; +- report `NotFound` for identities it did not admit rather than fabricating content. + +Expansion of the fragment graph reconstructs the same exact nodes. Collapsing the original graph to those fragment references preserves every Root BlueId. + +### E.7 Cyclic-member edges in fragments + +A finalized cyclic-set member identity `MASTER#index` is an opaque edge. An ordinary fragment may preserve that reference but MUST NOT claim that the member body is independently verifiable under that identity. + +An ordinary fragment provider therefore returns `NotFound` for the member unless it is composed with a cyclic-aware provider that verifies the complete owning set and member index. `this#index`, `ZERO_BLUEID`, malformed member suffixes, inline host object cycles, and cycles among ordinary local fragments remain invalid. + +A pure cyclic-set member is not an independently verifiable ordinary Root. A higher runtime may reject it as a processing Root while still permitting ordinary documents and events to contain opaque member references. + +*End of Blue Language Specification 1.0.* diff --git a/src/main/resources/transformation/InferBasicTypesForUntypedValues.blue b/blue-language-core/src/main/resources/transformation/InferBasicTypesForUntypedValues.blue similarity index 100% rename from src/main/resources/transformation/InferBasicTypesForUntypedValues.blue rename to blue-language-core/src/main/resources/transformation/InferBasicTypesForUntypedValues.blue diff --git a/src/main/resources/transformation/ReplaceInlineTypesWithBlueIds.blue b/blue-language-core/src/main/resources/transformation/ReplaceInlineTypesWithBlueIds.blue similarity index 100% rename from src/main/resources/transformation/ReplaceInlineTypesWithBlueIds.blue rename to blue-language-core/src/main/resources/transformation/ReplaceInlineTypesWithBlueIds.blue diff --git a/src/main/resources/transformation/Transformation.blue b/blue-language-core/src/main/resources/transformation/Transformation.blue similarity index 100% rename from src/main/resources/transformation/Transformation.blue rename to blue-language-core/src/main/resources/transformation/Transformation.blue diff --git a/blue-language-core/src/test/java/blue/language/runtime/LanguageProcessingTest.java b/blue-language-core/src/test/java/blue/language/runtime/LanguageProcessingTest.java new file mode 100644 index 00000000..d33b2b10 --- /dev/null +++ b/blue-language-core/src/test/java/blue/language/runtime/LanguageProcessingTest.java @@ -0,0 +1,1164 @@ +package blue.language.runtime;

+ * + *

Extension. Configure providers, immutable cache policy, + * runtime type registries, gas, evidence, and observers through + * {@code BlueRuntime.Builder}. Do not subclass the final composition types or + * add ecosystem-specific semantics here. Language extension SPIs live under + * {@code blue.language.provider}; generic Contracts SPIs live under + * {@code blue.language.processor}.

Contents. This package contains Blue nodes and schemas, + * serialization adapters, identity-provider hooks, graph-copy support, and + * structural path editing. Resolution, provider access, canonical hashing, + * Contracts processing, and runtime caching do not belong in the model.

+ * + *

Entry points. Authors construct + * {@link blue.language.model.Node} and {@link blue.language.model.Schema}; + * {@link blue.language.model.NodePathEditor} provides explicit structural path + * reads, writes, and pattern selection. {@link blue.language.model.Nodes} + * supplies narrow shape predicates and canonical scalar factories.

+ * + *

Lifecycle. Nodes and schemas are mutable DTOs and are not + * thread-safe. Callers own the graphs they construct or receive unless an API + * explicitly returns an immutable snapshot; use deep cloning or snapshot + * conversion before sharing mutable graphs.

Fixture runners, fixture packages, validators, +release reports, and the conformance CLI are tooling and must be selected +explicitly. This keeps normal runtime consumers free of fixture payloads and +prevents conformance from becoming a semantic dependency. + +### Ownership means the physical path + +Each production file has exactly one owner: the project whose conventional +source or resource root contains it. In the ownership manifest, `currentPath` +and `targetPath` are therefore identical. Root `src/main/**` is empty and +module build scripts may not redirect their source sets back to it. Published +projects may not split an exact Java package. + +The ownership manifest is generated from the physical module roots in sorted +path order. It records the source and resource counts and SHA-256 identities of +the newline-delimited paths.

The four +review classifications remain: + +- `compatible-relocation-through-aggregate-facade`; +- `internal-type-removed-from-public-surface`; +- `new-supported-api-spi`; +- `intentional-next-major-break`. + +Package changes in `1f79996` are explicit history, not accidental additions. +This includes `NodeProviderOutcome` moving to `blue.language.api`, snapshot +resolution/cache types moving to `blue.language.merge`, runtime access moving +to `blue.language.runtime`, and the immutable patch API moving to +`blue.language.snapshot`. Nested public types inherit the same recorded move. +Earlier 1.0 names are also associated by their unique binary simple name so a +supported relocation remains distinguishable from a genuinely new SPI. + +The classification does not require an internal implementation type to remain +public. It records the reviewed migration intent while module-local API +baselines enforce the final binary surface. + +### External dependency ownership + +All root, module, and included-build Gradle scripts are discovered on every +generation. Typed convention sources that add dependencies programmatically +are discovered as well. Every directly declared external library and every +versioned plugin has one reviewed owner, version, target configuration, +rationale, and a sorted list of its actual declaration sites. + +- Jackson databind belongs to the model wire boundary. +- YAML and RFC 8785 implementations belong to Language core. +- classpath discovery belongs to mapping and is not a semantic input; +- Apache HTTP belongs only to IPFS; +- fixture-manifest SnakeYAML belongs only to conformance; +- JReleaser, JMH, ASM, Mockito, and build-logic test dependencies belong to the + included build or root verification scope. + +The report separately records direct runtime allowlists per published module. +HTTP, reflection scanning, and fixture-manifest YAML are forbidden in Language +core. A new or removed declaration makes generation and the architecture gate +fail until ownership is reviewed. + +### Build shape is an architecture boundary + +The root build applies orchestration only and remains at most 200 lines. Every +module build remains at most 150 lines, no checked build script may reach 1,000 +lines, and modules use their conventional local roots.

The +Phase-B classifier now materializes the admitted selected scope/header chain +before pruning it, preserving selected dependency headers and processor state +while leaving unrelated siblings and executable bodies cold.

Its +`PlatformLocalityState` prepares and closes a fresh single-use invocation at +`Level.Invocation`, outside the method score. The method consumes request +count, backend trips, backend bytes, unrelated-provider requests, +selected-body demand, and unselected-body demand. Those counters prevent +benchmark-code elimination and describe locality; none is portable gas or a +semantic input. + +`processPlatformCommitIncludingSetup` has parameter-only JMH state. Its timed +method constructs the scenario, Language scope, Contracts service, provider, +plan, Root, and Event; applies the requested warm/cold policy; calls PROCESS; +consumes the same locality counters; and closes the invocation. Use this lane +for complete per-call time and allocation observations. It intentionally +includes setup and close and must not be described as PROCESS-only latency. + +The final-quality gate requires the PROCESS-only public platform method, in +addition to the reference-validation and warm-selection smoke benchmarks. +Final-quality JMH smoke uses zero warmup iterations, one 25 ms measurement +iteration, and one fork; it proves that each required benchmark executes, not +that it meets a performance threshold. `benchmarkClasses` still compiles the +setup-inclusive lane, but final quality does not multiply that intentionally +expensive full-fixture allocation campaign into the required release smoke. + +For complete per-call allocation observations, build the executable JMH jar +with Gradle and add JMH's GC profiler to the setup-inclusive method: + +```bash +./gradlew --no-daemon jmhJar +JMH_JAR="$(find build/libs -maxdepth 1 -type f -name '*-jmh.jar' \ + -print | sort | tail -n 1)" +test -n "$JMH_JAR" +java -jar "$JMH_JAR" \ + '.*DeepGraphPhysicalLocalityBenchmark\.processPlatformCommitIncludingSetup$' \ + -prof gc +``` + +Use one parameter tuple and deliberately minimal iteration settings only as an +execution smoke while editing the harness: + +```bash +java -jar "$JMH_JAR" \ + '.*DeepGraphPhysicalLocalityBenchmark\.processPlatformCommitIncludingSetup$' \ + -p representation=INLINE \ + -p cacheMode=COLD \ + -p batchMode=UNBATCHED \ + -wi 0 -i 1 -f 1 -r 25ms -prof gc -foe true +``` + +That command proves the entry executes and exposes profiler fields; its single +short iteration is not publishable performance evidence. Omit the three `-p` +restrictions to exercise all sixteen tuples, and use enough warmup, iterations, +and forks for the intended measurement campaign. + +Interpret `gc.alloc.rate.norm` as approximate bytes allocated per measured +operation and `gc.alloc.rate` as throughput-dependent allocation per second. +`gc.count` and `gc.time` describe collections observed during the fork; they +are noisy and are not latency or conformance assertions. In the setup-inclusive +lane, `gc.alloc.rate.norm` covers the complete timed lifecycle plus unavoidable +JMH measurement overhead. In the PROCESS-only lane, setup and teardown remain +outside the method score and profiler accounting around invocation hooks may be +harness-dependent. Do not label either value as processor-internal allocation; +report the exact benchmark method and parameter tuple. + +There is no retained hidden warm state between measured platform invocations. +Both lanes create and close a fresh scenario, Language scope, Contracts +service, provider, plan, Root, and Event for each single-use call. `WARM` +explicitly primes only permitted provider content, while `COLD` leaves that +invocation's measured provider cold. Preparation and warming are outside the +`processPlatformCommit` score and inside the +`processPlatformCommitIncludingSetup` score; always report the two methods and +warm/cold modes separately. + +The collection-path campaign can be run independently at one smoke size with: + +```bash +./gradlew :blue-contracts-core:jmh \ + -PblueJmhIncludes='.*EmbeddedCollection.*' \ + -PblueCollectionJmhSize=10 +``` + +Multiple comma-separated regular expressions are accepted.

Reuse external Timelines without creating a Timeline per process + +Several embedded process occurrences may use the same exact Timeline, actor, or Channel definition. + +```yaml +contracts: + teacherChannel: + blueId: +``` + +is equivalent to materializing the exact Channel node whose BlueId is supplied. Reusing the node does not copy Timeline history. Each scope occurrence still has its own path, lifecycle state, checkpoint state, and document state. + +A single provider subscription may serve many logical bindings. Concrete Channel subscription and event keys determine which scope occurrences are candidates. + +## 3. Participant roles are bound explicitly when an occurrence is created + +Reusable types define local semantic roles, not parent lookups: + +```text +teacherChannel +studentChannel +buyerChannel +sellerChannel +``` + +A concrete process occurrence supplies exact Channel values for those keys. The values may be inline or pure references. + +The occurrence is self-contained after creation. Existing occurrences do not silently change when a parent Channel changes. + +Recommended application behavior is: + +```text +new occurrence: + use the enclosing document's current participant configuration + +existing occurrence: + retain the exact bindings used when it was created + +local participant change: + use an explicit workflow inside the occurrence + +agreement-wide migration: + explicitly update or replace selected existing occurrences +``` + +The pre-change Channel snapshot governs the event that introduces a new participant set. The new subscription surface becomes active only after commit. This permits Alice and Bob to authorize a transition to Alice and Celine, after which Alice and Celine govern later events. + +## 4. No informal live Parent Channel in Contracts 1.0 + +Contracts 1.0 does not define: + +- `Parent Channel`; +- nearest-ancestor contract lookup; +- implicit import of parent Channels; +- live rebinding based on raw key equality; +- context-dependent child behavior based on whichever document embeds it. + +The same child BlueId therefore does not acquire different participant semantics merely because it appears beneath a different parent. + +A future cross-scope Channel port remains possible, but it must be an explicit separately published runtime type with complete rules for dependencies, subscription invalidation, checkpoint domains, cycles, ordering, gas, and missing targets. It must not be inferred informally. + +## 5. Contract entries are not embedded scopes + +`Process Embedded` continues to reject paths through `/contracts` and all other Language-reserved fields. + +A Channel may be ordinary identity-bearing Blue content and may itself contain a `contracts` field as data, but the generic processor discovers executable contracts only from the effective `contracts` map of participating scopes. A contract entry is not made into a child process by embedding `/contracts/`. + +Governance of a parent Channel should normally be expressed through sibling operations and workflows at the parent scope, or through a separate ordinary embedded governance module that emits an event observed by the parent. + +## 6. Dynamic process collections use `collectionPaths` + +`Process Embedded` now supports two explicit declaration forms: + +```yaml +contracts: + embedded: + type: Process Embedded + + paths: + - /payment + + collectionPaths: + - /lessons +``` + +`paths` declares one exact embedded scope per pointer. + +`collectionPaths` declares that every direct ordinary member of an object-compatible collection is one embedded scope: + +```text +/lessons/lesson-17 +/lessons/lesson-18 +``` + +The collection container itself is not implicitly a scope. + +## 7. Stable object keys, not list positions or wildcards + +Contracts 1.0 does not interpret: + +```yaml +paths: + - /lessons/* +``` + +as a wildcard, and it does not interpret a path to a List as “embed every item.” + +Dynamic embedded collections use stable object keys. This avoids renumbering scope paths, activation intervals, checkpoints, and audit references when a list item is inserted or removed. + +A collection target must be object-compatible. Every present direct member must be an object or a verified pure reference to an object. + +## 8. Creating a new member makes it active on the next revision + +A workflow may append a complete new Lesson under a stable key and inject existing participant Timelines or Channel references: + +```yaml +op: add +path: /lessons/lesson-17 +val: + type: Lesson + contracts: + teacherChannel: + blueId: + studentChannel: + blueId: +``` + +The creating event does not also process the new Lesson. After the Root commits: + +- the new concrete scope path is indexed; +- its subscription interval starts strictly after the creating event; +- it is fully active for the next eligible event. + +Removing a member retires its occurrence. Re-adding the same key begins a fresh interval and checkpoint lineage. + +## 9. Same exact child content at two keys means two owned occurrences + +This is valid: + +```yaml +lessons: + lesson-a: + blueId: + lesson-b: + blueId: +``` + +The exact initial content is shared, but the occurrences are independent. Processing `lesson-a` creates a new state at `/lessons/lesson-a`; `/lessons/lesson-b` remains unchanged. + +Shared mutable state must be an autonomous Root. Reusing an initial BlueId does not create shared mutation. + +## 10. Event targeting remains Channel-specific + +`collectionPaths` defines which nodes are active scopes. It does not define the addressing protocol for external events. + +Every concrete External Channel type defines its own finite subscription and event keys. A Timeline protocol may use: + +```text +documentId + timeline identity + actor identity +``` + +so that many Lessons reuse Alice's Timeline while one Timeline Entry targets exactly one Lesson document occurrence. + +The stable protocol document identity identifies the continuing occurrence. The BlueId identifies one exact immutable state of that occurrence. + +Generic Contracts does not require a field literally named `documentId`; it requires the exact Channel runtime to publish deterministic keys and acceptance semantics. + +## 11. Composite Channel versus Group Timeline + +A logical group of existing participant Channels is a concrete Composite Channel concern, not a new “Group Timeline.” A Group Timeline would mean one provider-maintained shared append-only history, which is a different concept. + +Composite OR, quorum, unanimous approval, and membership governance are concrete runtime/workflow semantics outside the generic Contracts core. Participant changes that require several approvals should be represented as explicit stateful workflows rather than inferred from group membership alone. + +## 12.

Defensive +copies prevent caller mutation from changing the admitted graph. Plain +provider misses remain `NOT_FOUND`; invalid stored evidence is reported as +`INVALID_EVIDENCE`. + +A finalized cyclic-set member reference, `MASTER#index`, is an opaque external +edge. The direct fragment preserves that exact reference and records it in its +edge metadata, but the local fragment map and provider do not claim content +under the member identity. A composed `CyclicAwareNodeProvider` may supply it +only with the owning set proof; a plain provider cannot make a member valid by +hashing its content independently. `this#index`, `ZERO_BLUEID`, malformed +member suffixes, materialized content that claims a member identity, inline +object cycles, and cycles among local ordinary fragments remain invalid. +Verified member content is never inserted into an ordinary canonical cache +under `MASTER#index`; that cache requires a standalone hash, which a cyclic +member deliberately does not have. Providers claiming cyclic awareness must +prove that the base identity is an admitted complete set and that the requested +index is a member—an ordinary node stored under the base cannot counterfeit +`base#0`. + +The helper's fragments are deliberately ordinary provider content. A storage +runtime may choose coarser exact fragments—for example, a complete selected +executable body—or finer direct fragments. The semantic constraint is the +exact BlueId at each replaced edge, not the physical page size. + +## Pure-reference Root and Event admission + +For Node entry points, processing performs the following read-only admission +before semantic execution: + +1. If Root or Event is a pure reference, request exactly that identity through + the invocation's verified `ProcessingSnapshotManager`. +2. Verify that the returned direct content calculates to the requested BlueId. +3. Derive or validate immutable external-delivery evidence. +4. Open only the ancestor closure of evidence-selected scope paths. +5. Start `ProcessorEngine` from a deferred snapshot rather than resolving the + complete transitive Root. + +Snapshot-native entry points apply the same top-level check to the snapshot's +canonical Root. Supplying a resolved companion cannot turn a pure cyclic member +into an independently processable Root. + +The Event-scoped external-channel context can materialize an exact reference +needed by registered immutable event functions. The default subscription-key +projection uses that boundary for referenced `subscriptionKey` or +`subscriptionKeys` fields. Header-time use fails closed: event evidence is not +available while constructing the revision-complete subscription surface. + +Contract recognition continues to open exact contract contributions and type +headers. Executable body fields remain pure references until a matching +handler has been selected. A selected body is then fetched and verified once. +Unselected handlers and unrelated embedded branches are not opened merely +because they exist behind Root. + +On mutation, persistent patching rebuilds the changed scope and its ancestor +spine to Root. Unchanged siblings retain their exact identities and, for +snapshot-native execution, their frozen structural instances. The resulting +Root remains ordinary Blue: it can be collapsed to one pure Root reference and +expanded through its exact fragment set without changing its BlueId or value. + +The locality fixtures deliberately store External Channel and Handler headers +as independent exact fragments while retaining the processor-managed +initialization marker inline for direct reserved-state validation. Runtime +type definitions come from the verified registry provider, selected Handler +bodies come from separate fragments, and unselected bodies stay cold. + +## Semantic demand versus physical acquisition + +The portable execution model records logical contract recognition, selected +body demands, handler work, patches, checkpoint work, and Root events. It does +not charge provider calls, bytes, cache hits, transport pages, or batch shape. + +Consequently: + +```text +semantic demand + logical gas + canonical work trace + are portable + +provider calls + provider bytes + cache hits + backend batches + are host diagnostics +``` + +A warm cache may eliminate backend reads, and a provider may prefetch a +bounded batch, without changing the logical demand set, gas, result, or trace. +Invalid evidence is deterministic. Transient `UNAVAILABLE` evidence uses the +noncommitting attempt/suspension boundary. Definitive absence does not prove a +semantic field is absent unless a complete exact direct node or manifest +establishes that fact. + +## Source classification and logical handler delivery + +External source classification and handler dispatch are separate immutable +phases. + +An External source member has registered subscription, acceptance, payload, +and checkpoint functions. A read-only Channel member is narrower: it proves +that one effective same-scope contract is an External or processor-managed +Channel and freezes only its key, order, effective type, ordered source +contributions, role, deterministic header dependencies, and sanitized header +identity. It grants no source acceptance, checkpoint, handler execution, or +executable-body capability. + +During subscription-header evaluation, a runtime that knows one fixed target +uses `dependOnSameScopeChannel(key)`. A runtime whose event can name any target +uses `dependOnSameScopeChannelCatalog()`. During event evaluation, +`channel(key)` may read only a header covered by that retained declaration. +The whole-catalog dependency records both every Channel header and the +canonical raw-key membership of the effective contract map. Consequently an +empty result proves exact absence, while a present non-Channel key fails +distinctly without recognizing that unrelated header. + +The dependency snapshot is stored in the active subscription interval and +participates in its checkpoint-domain identity. Phase B reconstructs the raw +External source plus exactly the declared Channel headers. Executable bodies +remain preserved references, and unrelated contract headers are not recognized +merely because they are inline. A removed, retyped, reordered, or replaced +dependency causes retained evidence to fail rather than becoming a false +negative. Missing provider evidence uses the existing noncommitting resource +acquisition boundary. + +Each accepted-new source evaluation retains: + +- its raw source channel and checkpoint domain; +- its exact frozen payload and checkpoint subject; +- a same-scope handler-selection channel; and +- a deterministic logical-delivery key. + +The defaults return the raw source channel for both keys, preserving the +one-source/one-dispatch behavior of existing runtimes. + +After rejected and stale sources are removed, accepted-new evaluations are +grouped by `(scope path, logical-delivery key)`. Members of one group must name +the same handler-selection channel and the same exact payload identity. +Routing output is validated before mutation. Every peer target must have been +declared exactly or through the catalog; only the source key is implicit. The +selected read-only target snapshot is frozen with the classification and +compared with the fully preflighted same-scope Channel again before Phase C +mutation. + +One valid group executes its target handlers once. Every fresh participating +raw source owns a checkpoint write, but those writes become authoritative only +after the handler and its internal event drain complete successfully. A +failure, termination-before-checkpoint, gas exhaustion, cut-off, or rollback +commits none of the group's source checkpoints. A stale or rejected source is +not a participant. The target channel is never evaluated or checkpointed as an +external source unless it independently appeared as an accepted source. + +The grouping plan is run-local and is not exposed through `ProcessResult`. + +## Runtime extension rules + +`ExternalChannelSubscriptionFunctions` is the only runtime-specific extension +surface involved here. Implementations may use the immutable +`ExternalChannelFunctionContext` to: + +- declare and inspect one exact same-scope Channel header; +- declare a bounded same-scope Channel catalog and perform one exact event-time + key lookup; +- inspect genuine same-scope External-source dependencies; +- enumerate a shallow effective-type family; +- match exact inline or referenced candidates against a Blue pattern; +- materialize an exact event-scoped reference; and +- select a handler channel and logical-delivery identity. + +These functions must be deterministic and representation-blind. They cannot +perform ambient I/O, inspect mutable post-start state, invent source +occurrences, or demand executable bodies to decide routing. + +## Effective fragmentation catalog + +Application-specific splitters can inspect the kernel's effective boundaries +without executing contracts by calling +`documentProcessor.administration().effectiveFragmentationCatalog(root)` or +the high-level `blueContracts.effectiveFragmentationCatalog(root)`. + +The immutable result reports the exact Root BlueId, effective +`Process Embedded` concrete paths by scope, the structured immutable plan that +produced each path from an exact declaration or stable collection member, and +ordered effective contract snapshots by scope. Each snapshot exposes its raw +key, effective runtime type, runtime role, +ordered exact source-contribution identities, sanitized immutable header +fields, registered executable-body field names, and exact present body BlueIds +by field. It never assigns an identity to a synthetic merged contract and +never fetches a body merely to report the BlueId already present at its edge. + +Inspection uses the processor's verified snapshot/provider context, so inline, +partially materialized, pure contracts-map reference, and pure Root reference +forms produce the same catalog. Inherited contracts and inherited +`Process Embedded` declarations are included. Unsupported effective types fail +closed. Discovery follows only declared participating scopes: a referenced +exact child is opened when its effective `paths` entry is known; a collection +target or direct member is opened only as needed to freeze `collectionPaths` +membership; unrelated data and unselected executable bodies remain cold. +Registered body fields and the Handler event edge are preserved before Language +resolution. The operation is read-only and outside Contracts gas. + +## Deliberate limits + +- A whole ordinary Root or Event may contain or be typed by an opaque finalized + cyclic-member reference.

A target item like -`{ blueId: X }` must be present at that position and must match exactly; it is -not treated as an optional label-only placeholder. - -If a candidate list already exposes enough item positions for the explicit -target list pattern, the matcher does not reconstruct or fetch the first item -just to check whether it is a multi-document bundle. It reconstructs only when -the pattern asks for positions that are not visible in the current list surface. -If the visible first item is already the exact pure-reference item requested by -the first target position, reconstruction is also skipped: that first reference -is an item identity, not a possible hidden bundle for this match. - -For schema-only list checks, such as: - -```yaml -values: - type: List - schema: - minItems: 2 - maxItems: 2 -``` - -the matcher reconstructs the list surface so cardinality can be checked, but it -does not expand every item reference. Item references are only fetched when the -pattern requires concrete item conformance, such as `itemType`. - -### itemType - -When the target pattern uses `itemType`, each candidate item must conform to -that item type. - -If an item is already the exact requested reference, no fetch is needed. If the -item is a different reference, the matcher fetches that item so it can check -whether the concrete item conforms to the requested item type. - -This is intentionally stricter than only checking list metadata. A list with -`itemType: Text` can still match a more constrained item type if every concrete -item conforms to that constrained type. - -### Dictionaries - -An explicit object-property pattern requires a dictionary-shaped candidate. A -scalar or list candidate does not match an object pattern just because the -requested fields are optional labels. A candidate is dictionary-shaped when it -has object fields, a `keyType`, a `valueType`, or a declared `Dictionary` type. - -For dictionary `keyType`, the matcher needs only keys, not values. - -For dictionary `valueType`, the matcher checks every value. Exact reference -matches do not require a fetch. Non-exact referenced values are fetched only -when needed for concrete conformance. - -Collection metadata also implies payload kind when the candidate node exists: -`itemType` requires a list-shaped candidate, while `keyType` and `valueType` -require a dictionary-shaped candidate. - -Schema `minFields` and `maxFields` require the dictionary field surface, but do -not require expanding every value. - -### Caller Limits Still Win - -The compatibility matcher always composes caller limits with pattern limits. -Both must allow a path before the candidate is extended there. - -Example: - -```yaml -candidate: - x: - blueId: - -pattern: - x: - y: 1 -``` - -With caller limits restricted to `/other`, the matcher returns false and does -not fetch ``. - -With caller limits allowing `/x/y`, the matcher may fetch `` and check -`x.y`. - -Caller path limits use RFC 6901 JSON Pointer escaping. A key named `a/b` is -bounded as `/a~1b`, and a key named `c~d` is bounded as `/c~0d`. This keeps -global limits and matcher-internal literal path tracking aligned. - -## FrozenTypeMatcher - -`FrozenTypeMatcher` performs matching over immutable `FrozenNode` objects. - -It keeps three per-matcher caches: - -- resolved references by blueId, -- unresolved references by blueId, -- subtype checks by candidate/target type identity, -- match results by candidate/target blueId pair. - -The caches are local to the matcher instance, which makes repeated matching in a -processor run cheap without mutating the matched nodes. - -### Reference Matching - -A target pure reference matches when any of these identities matches: - -- the candidate is the same pure reference, -- the candidate's computed frozen blueId is the target blueId, -- the candidate's declared type identity is the target blueId. - -This lets these common forms match correctly: - -```yaml -x: - blueId: -``` - -and: - -```yaml -x: - type: - blueId: -``` - -### Declared Type Matching - -If the target pattern declares a type, matching succeeds when: - -1. the candidate's declared type is the same type or a subtype, or -2. the candidate structurally conforms to the resolved type definition. - -Type compatibility is label-neutral. `name` and `description` affect BlueId, but -they do not affect matching, conformance, subtype compatibility, or -structural/type equality. A matching display name is not enough to prove type -equality, and a different display name or description is not enough to disprove -it. The matcher compares a label-neutral structural identity for inline type -definitions. - -The second case matters for event/request payloads where a node may not carry a -fully explicit declared type, but its payload still conforms to the requested -contract type. - -Core payload kinds are also checked: - -- `Text` requires a string value when a value is present, -- `Integer` requires `BigInteger`, -- `Double` accepts numeric `BigDecimal` or `BigInteger`, -- `Boolean` requires boolean, -- `List` requires list payload shape, -- `Dictionary` requires object/property payload shape. - -Untyped programmatic scalar payloads can match core primitive patterns when the -payload value has the correct Java representation. This matters for processor -events built directly as `Node` objects rather than parsed through the Blue -preprocessor. - -Untyped list and dictionary payloads can match core `List` and `Dictionary` -patterns when their payload shape is unambiguous. - -### Schema Matching - -The frozen matcher verifies the schema keywords currently supported by the Java -schema verifier: - -- `required` -- `minLength` -- `maxLength` -- `minimum` -- `maximum` -- `exclusiveMinimum` -- `exclusiveMaximum` -- `multipleOf` -- `minItems` -- `maxItems` -- `uniqueItems` -- `minFields` -- `maxFields` -- `enum` - -String length is counted by Unicode code points. Regex pattern validation is -outside the Blue Language 1.0 schema vocabulary; contract libraries can perform -regex validation as runtime behavior when they define exact execution semantics. - -### Presence Semantics - -Missing optional target properties or items are allowed when the target pattern -does not contain meaningful value/payload requirements. - -A missing property or item fails when the target has: - -- `schema.required: true`, or -- a nested value/payload requirement. - -This preserves the old "optional unless value-bearing or required" behavior -without resolving target patterns as standalone documents. - -### Lazy Reference Resolution - -In direct frozen matching, a candidate pure reference may be lazily resolved if -the target requires structural conformance. This supports direct use of -`FrozenTypeMatcher` on frozen nodes that still contain references. - -In mutable compatibility calls with explicit caller limits, lazy candidate -reference resolution is disabled. The candidate must already have been extended -through the limit-controlled path. This is what keeps caller limits authoritative. - -Target type definitions may still be resolved, because they are part of the -pattern semantics rather than candidate traversal. - -Both successful and failed reference resolutions are cached inside the matcher. -This means repeated checks against the same resolved reference do not refetch it, -and repeated checks against the same missing reference fail without repeatedly -hitting the provider. - -## Performance Model - -The intended cost is: - -```text -O(observed_pattern_paths + needed_reference_fetches + local_schema_checks) -``` - -It is not: - -```text -O(full_candidate_document + full_resolved_type_graph) -``` - -Important cheap cases: - -- Exact pure reference pattern: no provider fetch. -- Nested pattern with one observed branch: fetch only that branch's owner. -- List cardinality check: fetch the list surface, not every referenced item. -- Dictionary key type check: fetch keys, not values. -- Snapshot matching: no provider fetch after snapshot resolution if the needed - graph is already frozen and interned. - -This is why the matcher is suitable for channel and handler matching. Most -handlers observe a small shape, and the matcher avoids resolving unrelated -parts of the event/document. - -## Example: Large Candidate, Small Pattern - -Candidate: - -```yaml -order: - blueId: -``` - -`` contains: - -```yaml -customer: - blueId: -lineItems: - type: List - items: - - blueId: - - blueId: -audit: - blueId: -``` - -Pattern: - -```yaml -order: - customer: - id: - type: Text - schema: - minLength: 5 - maxLength: 5 - status: - blueId: - lineItems: - type: List - schema: - minItems: 2 - maxItems: 2 -``` - -Expected behavior: - -- fetch `` once, -- fetch `` once, -- do not fetch `` because it is an exact reference check, -- do not fetch line items because only cardinality is checked, -- do not fetch audit because the pattern does not observe it. - -The test suite asserts exactly this fetch profile. - -## Tests And Coverage - -The matcher coverage lives in -`src/test/java/blue/language/utils/NodeTypeMatcherTest.java`. - -The suite covers the behavioral axes that matter for production matching: - -- basic type, value, and shape matching, -- inherited fixed values from referenced target definitions, -- optional and required schema properties, -- provider-backed required type definitions, -- all frozen schema keywords listed above, -- enum identity by canonical node blueId, -- nested lists and property shapes, -- exact blueId references against node identity and node type identity, -- `name` and `description` being ignored by matcher/type compatibility, -- same-named but structurally different type definitions not being treated as - identical, -- pure reference pattern leaves without candidate expansion, -- nested patterns that expand only required prefixes, -- caller-provided global limits composing with pattern limits, -- literal property keys containing `/`, -- global path limits using JSON Pointer escaping for `/` and `~` in keys, -- list schema cardinality without item-reference expansion, -- explicit three-item list patterns against list references and inline lists - with reference edges, -- explicit list patterns rejecting scalar/object candidates even when item - constraints are optional, -- pure-reference list positions being required when the target pattern names - them, -- three-position list patterns rejecting a candidate that only provides first - and last references in the wrong positions, -- extra list items being allowed unless schema cardinality constrains them, -- multi-document first-item bundles being reconstructed only when the target - pattern asks for hidden positions, -- exact first reference items avoiding bundle-reconstruction fetches, -- explicit object patterns rejecting scalar/list candidates even when child - field constraints are optional, -- collection metadata rejecting wrong payload kinds, -- dictionary key type without value expansion, -- dictionary value type with only needed non-exact value expansion, -- complex multi-level matching with asserted provider fetch counts, -- complex `itemType` conformance with asserted provider fetch counts, -- list item type enforcement across all items, -- narrower concrete item/value conformance despite broader metadata, -- implicit list and dictionary payloads, -- JSON-array-like event request payloads as implicit lists, -- dictionary key/value type enforcement, -- primitive core type payload mismatch rejection, -- untyped programmatic scalar events matching core primitive patterns, -- no mutation of input `Node` objects, -- direct frozen reference matching caching resolved references, -- direct frozen reference matching caching unresolved reference misses, -- direct frozen matching with no fetches after snapshot resolution, -- pointer-based `ResolvedSnapshot` matching through the path index, -- missing snapshot pointers matching only optional target patterns. - -These tests are intentionally not only pass/fail semantic checks. The complex -cases assert fetch counts per blueId, which proves the important performance -property: the matcher fetches only the references required by the observed -pattern and does not accidentally expand unrelated branches. - -## Final Local Verification - -The current local verification commands are: - -```bash -./gradlew test --tests blue.language.utils.NodeTypeMatcherTest -./gradlew test -``` - -Both pass in the current workspace. - -## Boundaries - -The matcher is ready for snapshot-backed channel and handler matching, but there -are broader runtime/spec concerns outside this class: - -- `schema.pattern` is intentionally unsupported in the core language; regex - validation belongs in contract/runtime code; -- cross-language golden fixtures should eventually verify shared matching, - hashing, and schema behavior; -- `deriveChannel`, `channelize`, and `isNewerEvent` now have Java processor SPI - hooks, but still need explicit spec treatment; -- the long-term processor path should pass `ResolvedSnapshot`/`FrozenNode` - values directly instead of using mutable `Node` adapters. - -Within the current Java implementation, the matcher now has the needed local -coverage for correctness, immutability, caller-limit enforcement, path handling, -schema/type semantics, and reference-resolution performance. +Type matching consumes immutable verified snapshots and cannot depend on +provider call count or cache warmth.

These are two physical representations of the same two semantic +inputs, not four semantic values. + + +```java + IndexedDeliveryPreparation preparation = contracts + .indexedDeliveryEvaluator() + .prepare( + indexedRoot, + indexedEvent, + rootRevision, + eventOrderKey, + completeActiveIntervals, + orderedCandidateOccurrenceKeys); + + PlatformProcessInvocation invocation = + PlatformProcessInvocation.builder() + .deliveryPlan(preparation.deliveryPlan()) + .nodeProvider(requestLocalProvider) + .build(); + + PlatformProcessingResult result = + contracts.processForPlatformCommit( + rootReference, + eventReference, + invocation); +``` + +Preparation runs in the evaluator's processor-owned runtime generation. The +`requestLocalProvider` becomes authoritative only when the platform PROCESS +call opens its invocation scope. In the example it must establish +`rootReference`, `eventReference`, and every exact reference demanded by the +selected processing path. + +`PlatformProcessInvocation` accepts a plan returned by the public indexed +evaluator. A separately assembled `ExternalDeliveryPlan.Builder` value has no +evaluator-established Root/event/registry binding and is rejected by the +invocation builder. The context retains one immutable plan and one borrowed +provider; it does not ask callers to assemble a potentially inconsistent plan +and `VerifiedExecutionEvidence` pair. + +This overload has exactly the same two Blue semantic inputs as every other +PROCESS call: + +```text +PROCESS(Root, event) -> ProcessResult +``` + +The plan, managed revision, active intervals, event order, provider, and commit +companion are host execution environment and evidence. Different physical +representations of the same Root/event therefore cannot choose different Blue +semantics. Before execution, Contracts checks the evaluator binding against the +Root BlueId, event BlueId, equal managed/indexed revision, event order, and the +active immutable runtime-registry identity. It then verifies the supplied plan +directly with the core delivery-plan and preselection verifier, including its +complete interval surface, exact-runtime-state certificate, active bounds, +delivery identities, dependency catalog, completeness, and canonical order. +Omitted, extra, duplicate, stale, inactive, wrong-order, wrong-revision, or +wrong-registry evidence fails closed. + +Direct verification is distinct from derivation. This overload never invokes +the `ExternalDeliveryPlanDeriver` captured when `BlueContracts` was built. The +existing `process(root, event)`, evidence overload, and current-Root +compatibility deriver keep their established behavior. + +The runtime-registry generation in that binding is also portable metadata, +not a Java implementation fingerprint. It is derived from the released +runtime package identity plus lexically ordered registered BlueIds, processor +kind, canonical-versus-provider type-evidence mode, declared type identities, +and ordered executable-body field names. Java class names, processor object +identity, and allocation identity are excluded. Equivalent registrations can +therefore establish the same evidence boundary in another runtime language. + +### One strict provider domain + +The supplied provider is used for every provider-backed read in the attempt: + +- Root/event and selected embedded-scope materialization; +- referenced contracts, schemas, type chains, Channel headers, declared + Channel dependencies, and selected Handler bodies; +- runtime value reads and patch-path opening; +- final soundness and subscription-surface validation. + +Language verifies every returned candidate against its requested BlueId. It +does not append the construction-time provider or bootstrap registry, consult +provider-derived state retained by another invocation, or publish discovered +provider content into the service's shared cache. Every call receives fresh +invocation-owned cache state; child processing sequences remain inside that +same provider domain. Concurrent calls on one `BlueContracts` generation can +therefore use different providers without cross-provider reads or cache +contamination. + +Provider batching, fragment count, cache temperature, call count, and latency +remain host metrics. They cannot change the semantic result, named portable-gas +trace, or admitted-gas total for equivalent exact evidence. + +The provider is borrowed. Closing the invocation scope clears invocation-owned +state but does not close the provider or the borrowed Language runtime. If the +request needs application, registry, or transport fallback, compose that +fallback into `requestLocalProvider` before the call. + +### Phase-B classification across representations + +Phase B classifies the exact feeder-selected source Channels and their declared +same-scope dependencies. For a pure-reference or fragmented Root, the +classification projection now materializes the admitted Root and selected +scope ancestor chain before pruning contracts. It retains selected headers, +processor-owned checkpoint and termination state, and required +`Process Embedded` routing markers. Selected executable-body paths and +unrelated reference branches remain authored and cold until a later phase +selects them. + +This order makes inline, pure-reference, partial, and fragmented Root forms +expose the same selected dependency surface without turning classification into +a whole-Root scan. The Phase-B/Phase-C dependency-equality check remains in +place: a real header, contribution, catalog, ordering, or dependency change is +still rejected as stale or invalid evidence. + +### Use the result atomically + +`PlatformProcessingResult.processResult()` is the five-field semantic result. +`commitCompanion()` carries the expected Root/event identity, expected and +resulting revision, external order, and verified subscription delta. Persist +both in one compare-and-swap transaction. A committing success advances the +Root revision and installs the returned Root/outbox; a noncommitting terminal +result retains the revision and advances only revision-bound delivery progress. + +## Current-Root compatibility deriver + +When a compatibility API requires `ExternalDeliveryPlanDeriver`, create one +from the same evaluator and the same complete active surface: + + +```java + ExternalDeliveryPlanDeriver deriver = contracts + .currentRootDeliveryPlanDeriver( + 2L, + ExternalOrderKey.of(Arrays.asList(141L, "event-43")), + completeActiveIntervals); +``` + +The returned deriver evaluates every active occurrence and computes the +physical candidate set internally. It is a convenience for an already indexed +current Root, not a recovery mechanism for lost activation history. A Root +scan cannot reconstruct historical activation boundaries. + +## Why the result is deterministic + +For the same exact Root, event, runtime registry generation, revision, order +key, active intervals, and candidate keys, the result is fixed because: + +- occurrence order is deeper scope first, then normalized RFC 6901 scope by + Unicode code points, contract order, channel key, and effective type; +- effective contracts retain exact type and ordered Source identities; +- provider content is verified against its requested BlueId; +- evaluation has an authoritative pass and an isolated full replay, and each + pass performs its own authoritative/diagnostic-twin function comparison; + registered host functions are therefore invoked four times per occurrence, + while only the designated authoritative meter admits call gas; +- activation uses explicit revision and total-order bounds; +- delivery and diagnostic collections are immutable and canonically ordered; +- no wall clock, randomness, thread schedule, cache state, or host object + identity enters the semantic inputs. + +JavaScript and other implementations reproduce the same result by implementing +the same Language/Contracts specification, fixture package, ordering rules, gas +manifest, portable registration metadata, and evidence boundaries. Java class +names and object identities are API/runtime conveniences, not part of the +semantic protocol. + +## Failure boundaries + +These operations fail closed. Important outcomes include: + +- `ExecutionEvidenceUnavailableException`: exact provider evidence is not + currently available; acquire the named BlueIds and retry unchanged input; +- `InvalidExecutionEvidenceException`: revision, candidate, header, dependency, + activation, or checkpoint evidence is inconsistent; +- `SubscriptionSurfaceInvalidException`: the Root cannot produce one finite, + canonical subscription surface; +- `PortableLimitExceededException` or `GasLimitExceededException`: the exact + manifest or invocation budget rejected the work; +- `IllegalStateException`: a borrowed runtime/service owner was closed or the + required verified snapshot generation is absent. + +Do not translate unavailable evidence into absence, retry deterministic invalid +evidence as though it were transient, or rebuild matching from private kernel +objects. diff --git a/docs/guides/schema-and-unconstrained-fields.md b/docs/guides/schema-and-unconstrained-fields.md new file mode 100644 index 00000000..d06210c4 --- /dev/null +++ b/docs/guides/schema-and-unconstrained-fields.md @@ -0,0 +1,43 @@ +# Schemas and unconstrained fields + +A schema constrains presence and value shape.

The baseline labels the numerical values provisional pending +calibration; the counter names, ownership, formulas, and trace order are the +implementation contract. + +## Language API + +The four Language operations remain: + +```text +expand <-> collapse +resolve <-> minimize +``` + +Demand-limited operations expose an explicit result instead of using a missing +node or provider exception to represent every outcome. Callers must distinguish +established values, proven semantic absence, incomplete evidence, and invalid +content. Incomplete results are not valid inputs to whole-document +canonicalization, Content BlueId calculation, or complete minimization. + +Provider integrations can distinguish exact content, definitive provider-domain +absence, transient unavailability, and invalid evidence. The legacy +`NodeProvider.fetchByBlueId` method remains available for compatible providers; +new providers should expose the richer result so Language operations do not +confuse provider state with semantic absence. + +The canonical `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` +nodes are loaded from the release registry files and verified against both +their file digests and published BlueIds. BlueId v1 itself is unchanged. + +### Fragmentation and finalized cyclic members + +`ExactNodeGraphFragments` now accepts a finalized `MASTER#index` pure +reference as an opaque edge inside an otherwise ordinary Root or Event. It +preserves the parent identity and direct-edge metadata but deliberately does +not publish a local fragment under the member identity. Compose its provider +with a `CyclicAwareNodeProvider` when member content is required; plain +independently hashed member content remains invalid evidence. + +This does not introduce independent member processing or mutation. A top-level +pure member is rejected as a `PROCESS` Root/Event, mutation and +`Process Embedded` traversal below an opaque member edge fail before provider +demand, and whole-edge replacement remains supported. + +Downstream splitters should use +`BlueContracts.effectiveFragmentationCatalog(Node)` or the lower-level +`DocumentProcessor.administration().effectiveFragmentationCatalog(Node)`. +The immutable catalog reports each structured embedded-scope plan—including +exact declarations, collection declarations, frozen member keys, concrete +paths, and provenance—and, for each scope, ordered +`EffectiveContractSnapshot` entries with exact source contributions, sanitized +header fields, registered executable-body field names, and present body BlueIds +by field. Inspection is provider-verified, body-cold, read-only, and outside +Contracts gas. + +## Contracts result and failure model + +The semantic operation remains: + +```text +PROCESS(document, event) -> ProcessResult +``` + +The completed result surface is: + +```text +status +document +events +totalGas +diagnostic? +``` + +`events` contains Root emissions only. The preview `triggeredEvents` alias was +removed. + +Completed status values are closed: + +```text +success +no-match +stale +terminated +invalid-processing-document +capability-failure +runtime-fatal +gas-limit-exceeded +portable-limit-exceeded +subscription-surface-invalid +``` + +Resource acquisition suspension belongs to `PROCESS_ATTEMPT` as +`NeedsResources`; it is not a completed status and carries no committed state, +events, progress, or portable gas. + +Every noncommitting result returns the exact input Root and an empty Root event +sequence. Runtime failure no longer writes a terminated marker or emits a +fatal lifecycle event. Graceful application termination remains a successful +business transition; a later invocation observes `terminated`. + +Gas is admitted run state, not a rollbackable application effect. A named +runtime child ledger is live-bounded and, when submitted, is merged immediately +before that handler's buffered patches, events, or termination request. If the +handler throws or a later effect fails, the Root and public events still roll +back, while the admitted child-ledger gas and its exact ordered trace remain in +`totalGas`. This is the Contracts 1.0 §12.3 rule that deterministic failures +report all gas admitted before the failure. + +### Additive indexed platform invocation + +Hosts that have already evaluated an exact indexed-delivery surface can now use +`PlatformProcessInvocation` with the additive +`BlueContracts.processForPlatformCommit(Node, Node, +PlatformProcessInvocation)` overload. The immutable invocation carries the +`ExternalDeliveryPlan` returned by `IndexedDeliveryEvaluator.prepare(...)` and +one request-local `NodeProvider`. It does not expose processor internals or ask +the host to construct a separate evidence value. + +This is an execution-boundary addition, not a third semantic input. Root and +event remain the complete Blue input pair. Contracts checks the plan's hidden +evaluator binding against both exact identities, the managed/indexed revision, +external order, and the active runtime-registry generation, then sends the +complete supplied plan through the authoritative verifier. It does not invoke +the plan deriver captured during service construction. The prior PROCESS, +evidence, attempt, snapshot, and compatibility-deriver APIs remain unchanged. + +The runtime-registry generation is derived from portable registration +metadata: registered BlueIds, processor role, canonical-versus-provider type +evidence, declared type identities, and ordered executable-body fields. It is +not derived from Java class names, object identity, or processor instance +identity. The plan can therefore bind equivalent runtime-neutral registrations +without making Java implementation details part of Contracts evidence. + +The Language processing bridge adds strict-provider scope overloads. A strict +scope verifies exactly the provider graph supplied for that invocation, starts +with isolated provider-derived cache state, and never appends the +construction-time provider or bootstrap provider. Scoped runtime and +conformance capabilities keep every admission, match, type/reference read, +patch, and final subscription check in that same evidence domain. Scope close +does not close the caller-owned provider or borrowed Language runtime. The new +SPI methods have fail-closed defaults, preserving existing bridge linkage while +requiring a bridge to implement strict scopes before it can support this lane. + +The Phase-B dependency projection is also corrected for representation +invariance. It materializes the admitted Root and feeder-selected scope/header +chain before pruning, rather than pruning an opaque `{blueId: ...}` wrapper and +then resolving the full Root. Selected source and declared dependency headers, +processor state, and required embedded-routing markers remain available; +unselected sibling scopes and executable bodies remain cold. The existing +Phase-B/Phase-C equality check is retained, so genuine dependency drift still +fails closed. + +## Removed pre-release behavior + +The following preview behavior is not part of Contracts 1.0: + +- committed fatal termination and `Document Processing Fatal Error`; +- partial commit of effects produced before a deterministic runtime failure; +- public propagation of descendant events without an explicit Root emission; +- recursive serialized-payload-size gas at patch or event boundaries; +- a fixed-price fatal or out-of-gas closeout; +- caller-authored target occurrences, child processing sessions, child-commit + envelopes, or a public transitive effect log; +- processor history inherited from a type; +- checkpoints that are not bound to both raw channel key and checkpoint domain; +- `needs-resources` as a completed processor status. + +The removed fatal-error registry node is not retained as an executable runtime +type. Preview enum and method aliases were removed rather than carried into the +first public API. + +## Removed API and replacements + +This is an intentionally breaking pre-1.0 cleanup. The release does not retain +deprecated forwarding methods or compatibility-only carrier types. + +See the +[final JVM API report](language-1.0-contracts-kernel-1.0-api-report.md) +for the exhaustive HEAD-to-final member inventory, replacement map, and +checked-in baseline mechanics. + +| Removed preview API | Final API or migration | +| --- | --- | +| `Blue.reverse(Node/Object)` | Use `Blue.canonicalize(...)` for canonical identity input or `Blue.minimize(...)` for an author-facing minimized overlay. | +| `MergeReverser` and bare `reverse(...)` | Use `CanonicalIdentityInputBuilder` or `MinimizedOverlayBuilder`; the two operations no longer share an ambiguous name. | +| Candidate conformance identity/source constants | Use `FIXTURE_PACKAGE_IDENTITY`, `BLUE_SPEC_SOURCE`, and `CONTRACTS_FIXTURE_PACKAGE_IDENTITY`. | +| `Schema.get*Value()` numeric conveniences | Use the corresponding exact `BigInteger` getters, such as `getMinItemsExact()`. | +| Two-argument `SourceProviderEnvironment` construction | Supply the complete Language release, preprocessing, registry, and evidence identities. | +| Legacy trusted behavior behind `NodeProviderWrapper.unverified(...)` | The released descriptor remains for binary linkage, but now delegates to `wrap(...)` and verifies every provider leaf. `isExplicitlyHostTrusted(...)` remains linkable and always returns `false`; there is no trust bypass. | +| `ChannelDelivery`, `ChannelEvaluation.matchDeliveries(...)`, and `deliveries()` | Derive occurrences through `ExternalDeliveryPlan`/`VerifiedExecutionEvidence`; a channel evaluation is one `match(...)` or `noMatch()`. | +| Deprecated `ProcessorErrorCategory` aliases | Use the exact Contracts 1.0 diagnostic categories. | +| Anonymous `consumeGas(...)`, fixed gas additions, and fatal closeout shortcuts | Charge named child-ledger counters and submit the live-bounded ledger once. Submission merges it immediately into admitted run gas; later rollback still discards application effects, not that gas trace. | +| Committing fatal termination and fatal lifecycle aliases | Throw a deterministic runtime failure, or request ordinary graceful termination for a successful business effect. | +| `EmbeddedNodeChannel.childPath` | Use `sourcePath`. | +| Legacy checkpoint event maps/accessors | Use entries keyed by raw channel key with explicit domain and subject identities. | +| Legacy checkpoint pointer aliases | Use `relativeCheckpointEntry(...)`. | +| Legacy `ResolvedReferenceCache` alias/interner lane | Use verified canonical/resolved entries and structural interning. | +| `DocumentProcessingResult.triggeredEvents()` | Use `events()`. | +| Large mutable `Blue` service-locator surface | Use `BlueLanguage` for Language operations, `BlueContracts` for processing, or `BlueRuntime` when one owned composition root is useful. The retained `Blue` class is a thin 24-member convenience façade. | +| `blue.language.utils.BlueIdReferenceValidator`, `BlueIds`, identity-input builders, and identity helpers | Import the supported equivalents from `blue.language.identity`. | +| `blue.language.utils.MinimizedOverlayBuilder` and `MinimizedOverlayReconstructor` | Import the supported equivalents from `blue.language.resolve`; canonical identity construction remains in `blue.language.identity`. | +| `blue.language.utils.NodePathEditor` and `Nodes` | Import the stable value helpers from `blue.language.model`. `NodePathSelector` is internal; call `NodePathEditor.select(...)`. | +| `blue.language.utils.UncheckedObjectMapper` | Import `blue.language.codec.jackson.UncheckedObjectMapper` only when Jackson-specific integration is required; semantic code should normally use `BlueCodec`. | +| Public `blue.language.utils.limits.*` implementation classes | Use `ResolutionLimits` and its named factories/builder. Concrete stateful limit implementations are intentionally not API. | + +Production source is guarded by build checks that reject new `@Deprecated` +declarations and ambiguous bare `reverse` semantics. + +The checked-in `api/blue-language-java-1.0.json` file is the immutable +pre-modernization distribution baseline. Each published module owns its final +`api/public-api.txt` inventory, while +`api/modernization-api-migration-ledger-1.0.json` classifies the exact +baseline-to-final removals, relocations, and additions. `apiBaselineDiff` +protects each settled module surface and `verifySemanticApiMigration` proves +that the aggregate JVM delta is exactly the reviewed ledger—neither more nor +less. + +## Repository-independent provider boundary + +The Language API depends only on the generic `NodeProvider` contract. It does +not recognize a concrete repository, catalog artifact, or manifest. +`NodeProviderWrapper.unverified(NodeProvider)` is retained only as a binary +signature and delegates to the same strict direct-node verification as +`NodeProviderWrapper.wrap(...)`. Applications that explicitly admit authored +source documents use `ProviderEvidenceVerifier` with a fully bound +`SourceProviderEnvironment`. +`isExplicitlyHostTrusted(NodeProvider)` always returns `false`; no provider +entry point restores host-trusted evidence. + +## Generic hosted-runtime extension boundary + +Hosted runtimes now receive one processor-owned `RuntimeWorkSession` in each +deterministic processor phase. A runtime opens immutable, named counter +catalogs, charges live-bounded child ledgers before work, and submits their +ordered traces; the processor alone merges or discards them according to +success, deterministic failure, evidence suspension, or gas exhaustion. +Several independently named ledgers can additionally share one +invocation-owned `RuntimeWorkBudget`. Its weighted maximum is enforced before +child-trace or parent-reservation mutation, and exhaustion follows the same +structured session rejection path as the parent invocation limit. + +Transient runtime output must cross `SemanticOutputBoundary`, which returns an +immutable `ExactBlueValue` and meters semantic construction and changed +identity work. External Channel payload and checkpoint-subject functions use +that boundary automatically. Executing handlers can additionally use +`SelectedExecutableBody` to open only verified references reachable from the +selected exact body. + +Composite Channel implementations can declare a bounded subtype-family +dependency with `membersAssignableToType(...)`. Fragment splitters can consume +`ExecutableBodySourceDescriptor` to locate the exact owning contribution and +RFC 6901 pointer without rerunning overlay precedence or loading the body. + +Contracts 1.0 §4.9 binds each Handler to exactly one same-scope channel key, and +§7.7 starts from an accepted raw source `channelKey`. Context-aware +`ExternalChannelSubscriptionFunctions.handlerChannelKey(...)` can select a +different frozen same-scope Handler channel, while +`logicalDeliveryKey(...)` can coalesce several fresh accepted sources into one +handler execution. Eligibility and checkpoint ownership remain attached to +the accepted raw sources; the target is neither evaluated nor checkpointed +unless it independently appeared as a source. This supplies the generic +Coordination routing boundary without restoring caller-authored +`ChannelDelivery`. Application parsing of `request.channel`, authorization, +and registry policy remain downstream responsibilities. + +### Phase-B Channel dependencies + +Source semantics and target proof are intentionally separate: + +- `ExternalChannelMemberSnapshot` remains the surface for composing genuine + External sources and their subscription/checkpoint functions. +- `ChannelMemberSnapshot` is a read-only frozen header for any effective + External or processor-managed Channel. It exposes no acceptance, + checkpoint, execution, or executable-body capability. + +When the target key is fixed by the channel header, declare it with +`ExternalChannelFunctionContext.dependOnSameScopeChannel(key)`. When an event +may select any raw key, declare +`dependOnSameScopeChannelCatalog()` and use the event-only +`channel(key)` lookup. Every peer route must be covered by one of those +declarations; the source key alone is implicit. + +The retained active interval carries the exact Channel entries and, for the +whole selector, canonical effective raw-key membership. Phase B rehydrates +only the source and declared Channel headers. Thus a dynamic lookup can +distinguish exact absence from a present non-Channel key without recognizing +that unrelated contract. Bodies remain collapsed. Catalog additions, +removals, retyping, ordering changes, contribution changes, or header changes +rotate the checkpoint-domain dependency and invalidate stale retained +evidence. + +The selected target snapshot is frozen with classification and compared with +the fully preflighted Phase-C bundle before mutation. Selecting a target does +not evaluate it as an External source and does not create a target checkpoint. + +### Composite and All channel dependencies + +The generic External Channel SPI now exposes +`ExternalChannelFunctionContext`: + +- `member(key)` resolves one required same-scope External Channel and records + its exact, transitive header dependency; +- `members()` intentionally resolves and depends on the complete same-scope + External Channel surface; +- `membersByEffectiveType(typeBlueId)` returns shallow immutable snapshots for + one exact effective runtime-type family without recursively resolving other + families; +- `matchesPattern(candidate, pattern)` is available only to event-evaluation + functions and applies the frozen matcher through the captured verified + processing-snapshot boundary. + +The filtered view is the intended building block for an All-Timelines channel. +It avoids recursion between peer All channels and avoids making unrelated +External Channel types part of the All channel's domain. Its dependency retains +even an empty family selection, so adding the first matching member invalidates +the subscription. Matching member additions, removals, replacements, order +changes, contribution changes, and retyping likewise rotate the dependency. + +Captured member and type-family identities are carried by +`SubscriptionDelta.Entry`, included in `CheckpointDomain`, compared when +retained subscription intervals are revalidated, and included in the sparse +Root projection used to verify feeder evidence. A same-key member replacement +therefore retires and re-adds the dependent composite snapshot even when its +union of subscription keys did not change. + +This is runtime-neutral dependency context, not application-specific +Coordination behavior. A registered immutable function may route an accepted +occurrence through `handlerChannelKey(...)`; the default remains the +composite's own accepted raw channel key. + +Pattern matching uses one fresh matcher cache for each of the two deterministic +function-evaluation passes. Nested selected-member evaluation shares the cache +only inside its current pass. At pass completion the cache is cleared and the +manager-backed materializer is severed, so a retained context cannot match. +Non-core pure references are obtained solely through +`ProcessingSnapshotManager.materializeVerifiedExactReference`; +unavailable, still-reference-only, or identity-mismatched provider results are +errors rather than a negative match. The context clones and freezes both +arguments. Header-time functions, including `channelKeys` and checkpoint-domain +derivation and event-time header consistency recomputation, cannot invoke the +matcher directly or through `ExternalChannelMemberSnapshot.evaluate(...)` and +cannot cause provider demand. Exact canonical multi-hop type lineage is +supported, but this event-scoped primitive does not preprocess or merge +canonical definitions whose constraints depend on the broader Language +resolution pipeline. + +The same event-scoped context now exposes +`materializeExactReference(...)`. The default context-aware `eventKeys(...)` +uses it to project referenced `subscriptionKey` and `subscriptionKeys` +fragments, preserving inline/reference parity for the core finite-key +vocabulary. Application-specific projections—such as mapping a domain event +through a final Coordination registry—remain downstream policy. Header-time +materialization remains outside the generic kernel and fails closed. + +### Timeline checkpoint subjects + +`CHECKPOINT_SUBJECT` is an exact node, not necessarily a pure reference. A +Timeline runtime can return a minimal inline subject: + +```yaml +timeline: +timestamp: +``` + +The runtime stores that exact inline node in the checkpoint entry. +`ChannelCheckpointContext.currentSubject()` returns the current frozen subject; +`lastEvent()` returns the exact prior subject defensively, materializing and +verifying a pure-reference subject lazily only when requested. +`eventSignature()` and `lastEventSignature()` expose the corresponding subject +BlueIds without forcing materialization. A Timeline `isNewerEvent(...)` policy +can therefore enforce its same-timeline rule with a strict timestamp increase. +Composite and All functions can return the selected member evaluation's +checkpoint subject unchanged, and their newness policy sees that exact current +and prior pair. + +`VerifiedExecutionEvidence.eventOrderKey` continues to order feeder occurrences +and subscription activation intervals. It is not per-channel checkpoint +newness evidence and must not replace the Timeline comparison. + +## Refactored class map + +The kernel retains one processing algorithm and separates its phase ownership +as follows: + +| Owner | Final responsibility | +| --- | --- | +| `ProcessorEngine` | Top-level admission, one invocation run state, phase sequencing, result and diagnostic selection. | +| `ProcessingDocumentValidator` and `RootExternalDeliveryEvidenceVerifier` | Raw document admission and independent revision-bound feeder-evidence verification. | +| `ScopeExecutor` | Participating-scope preflight, initialization, external/internal delivery, cascades, cut-off, and quiescence. | +| `TerminationService` | Deferred graceful-termination lifecycle and marker completion. | +| `DocumentProcessingRuntime` | The invocation’s semantic reads, persistent mutation state, Document Updates, event queue, lifecycle writes, and work ledger. | +| `ImmutablePatchPlanner`, `PatchPlanningEngine`, and `BatchPatchTransaction` | Immutable patch planning, state-aware sequential planning, atomic commit/rollback, and changed-spine rebuilding. | +| `WorkingDocument` | Noncommitting read-your-writes previews over the same immutable patch machinery. | +| `ContractLoader` and `ContractContributionResolver` | Type recognition, must-understand enforcement, frozen effective snapshots, ordered Source contributions, dispatch projection, and selected body admission. | +| `ExternalChannelFunctionResolver`, `ExternalChannelFunctionContext`, and `ChannelMemberSnapshot` | Deterministic immutable source functions, exact/whole same-scope Channel-header declaration, Phase-B target lookup and freezing, External member/type-family composition, event-scoped verified matching, and checkpoint-domain contribution. | +| `EffectiveFragmentationCatalogBuilder` | Read-only effective `Process Embedded`, header, contribution, and executable-body-boundary inspection through the verified snapshot context. | +| `DeclaredTypeLineageMatcher` | Exact declared-type ancestry matching without structural guesses. | +| `ProtectedStateGuard`, `TypeGeneralizationPolicyResolver`, and `DirectSubscriptionSurfaceValidator` | Precommit protected-state, generalized-type, and subscription-surface validation. | + +These collaborators narrow ownership without introducing a second processor, +child commit path, or alternate semantic result. + +## Processor-managed writes + +Application patches and generated type-generalization writes create Document +Updates. Direct initialized-marker, checkpoint, checkpoint-cleanup, and +terminated-marker writes do not. Lifecycle channels are the observation +surface for initialization and graceful termination. + +All application effects are tentative until a successful result. Persistent +mutation rebuilds the changed direct container and ancestor spine while +retaining unchanged exact children by BlueId. Protected effective state, +active-scope cut-off, direct-container limits, and changed subscription surface +are checked before commit. Portable gas already admitted to the live invocation +meter is reported even when those effects roll back. + +## Conformance artifacts + +The vendored Language and Contracts fixture packages are exact copies of the +baseline packages. Their manifests are authoritative closed inventories. +Unknown operations, controls, projections, assertions, counters, and fixture +fields fail closed. + +The machine-readable implementation report records the release and package +identities above plus one pass/fail entry for every manifest-listed fixture. +There is no skip status. + +### Canonical fixture-envelope clarifications + +The final canonical package is retained byte-for-byte.

The runner keeps the derived delivery order at + zero and accepts the redundant hint only as the stable ordinal within that + same-scope, same-order tie. A value outside that exact tie ordinal still + fails closed as an order mismatch. +- `c-cyc-04` combines scalar shorthand `value: 0` with the authored `cyclic` + object edge. Before strict Language decoding, the conformance runner promotes + that scalar into its existing private fixture field and rewrites the + fixture-authored `/value` patch to the private field.

This lets the published limit exercise the intended + internal-event cycle; ordinary PROCESS inputs still pay initialization gas. + +The final identity-bound packages produce 153/153 Language passes and 154/154 +Contracts passes (96 behavior and 58 gas fixtures).

The runtime still owns checkpoints, handler dispatch, and gas -accounting. +It returns either `ChannelEvaluation.noMatch()` or one accepted, optionally +channelized event with an optional event identity. The evaluation cannot +manufacture more delivery occurrences. + +Application channel processors that can appear on the external subscription +surface must also expose deterministic immutable functions through +`externalSubscriptionFunctions()`. Those functions derive the finite +subscription-key set, checkpoint domain, and activation data used by +preselection and changed-surface validation. A registered external type +without supported functions fails closed. + +Context-aware functions can consult immutable same-scope channels through +`ExternalChannelFunctionContext`. `member(key)` and `members()` resolve exact +headers and record direct/whole-surface dependencies. Aggregate types such as +All-Timelines should use `membersByEffectiveType(timelineTypeBlueId)`: it +captures that exact type-family membership, including an empty selection, +without resolving peer aggregate or unrelated channel types. Member and +type-family identities are included in checkpoint-domain derivation, +`SubscriptionDelta.Entry`, retained-interval invalidation, and sparse feeder +evidence verification. + +Event functions can use `context.matchesPattern(candidate, pattern)` for the +same frozen structural/type matching semantics across inline nodes and pure +references. Each deterministic function-evaluation pass gets an independent +matcher whose only non-core materialization path is the captured +`ProcessingSnapshotManager` verified exact-reference boundary. Nested selected +member evaluation shares that pass-local matcher. Closing the pass clears the +matcher caches and severs its manager-backed materializer; retained contexts +reject later matching calls. Provider failures and identity mismatches +propagate; they are not cached as `false`. Header functions, including their +event-time consistency recomputation, cannot invoke the matcher directly or +through `ExternalChannelMemberSnapshot.evaluate(...)`. The strict callback +supplies exact canonical definitions rather than a fully +preprocessed/merged Language document; exact canonical type lineage is +followed, but definitions requiring broader resolution remain outside this +event-scoped primitive. + +Event functions can also use +`context.materializeExactReference(reference)` to obtain one exact direct +fragment through the same verified, event-scoped snapshot boundary. The +default context-aware `eventKeys(...)` uses this operation for referenced +`subscriptionKey` and `subscriptionKeys` fragments. Ambient and header-time +materialization remain forbidden; application-specific registry projections +are not defined by the generic kernel. + +After accepted-new classification, +`handlerChannelKey(...)` may select a different frozen same-scope Handler +channel and `logicalDeliveryKey(...)` may coalesce multiple fresh accepted +sources with the same exact payload. Defaults return the raw source key. +Handlers execute once per logical group; every participating raw source keeps +its own checkpoint, committed only after complete success. The target is not +evaluated or checkpointed as another external source unless it independently +appeared in verified delivery evidence. + +The pre-1.0 `ChannelDelivery` carrier and +`ChannelEvaluation.matchDeliveries(...)` multi-delivery API have been removed. +External occurrences can enter the kernel only through verified, +revision-bound `ExternalDeliveryPlan` evidence. ## Handler SPI -`HandlerProcessor` now has a channel derivation hook: - -```java -String deriveChannel(T contract, HandlerRegistrationContext context) -``` - -The default returns `null`. The loader first uses an explicit `channel`; when it -is absent, it calls `deriveChannel(...)`. The derived value must name a -registered channel in the same `contracts` map.

It wraps the -frozen matcher and supports: - -- pure `blueId` identity checks -- shape/property matching -- schema checks -- list and dictionary payload matching -- untyped programmatic scalar events matching core primitive patterns -- optional use of a `Blue` instance for provider-backed reference/type lookups - -When `DocumentProcessor` is created through `Blue`, the matching service is -provider-backed. Standalone `DocumentProcessor` instances still support local -frozen matching, but cannot resolve unknown external references unless a -matching service with `Blue` is supplied. - -## Runtime Flow - -External event processing is now: - -1. Load the scope contract bundle. -2. For each non-processor-managed channel in deterministic order: - - call `ChannelProcessor.evaluate(...)` - - skip if no match - - use returned deliveries, returned channelized event, or raw event - - apply checkpoint duplicate gating against the incoming external event - - call `ChannelProcessor.isNewerEvent(...)` - - run only handlers whose `HandlerProcessor.matches(...)` returns true - - persist the incoming external event after successful channel processing -3. Processor-managed channels still route internally: - - lifecycle - - document update - - triggered events - - embedded-node bridges - -All handler execution still goes through `ProcessorExecutionContext`, so patch -boundaries, gas, emissions, termination, and snapshot updates remain centralized. - -## What blue-contract-java Should Implement - -`blue-contract-java` should register processors for repository contract types, -for example: - -- `Conversation/Timeline Channel` -- `Conversation/Operation` -- `Conversation/Sequential Workflow Operation` -- `Conversation/Update Document` -- `Conversation/JavaScript Code` - -For operation/workflow contracts, channel binding should be derived by that -handler processor through `deriveChannel(...)`. The engine only needs the final -handler binding to a channel key. - -## Tests Covering This Base - -The current test suite covers: - -- original external events being stored in checkpoints while channelized events - are delivered to handlers -- multi-delivery channel evaluation with independent checkpoint keys -- same-scope composite channel evaluation through `ChannelEvaluationContext` -- event ids overriding canonical checkpoint signatures -- channel-specific stale event rejection through `isNewerEvent` -- handler channel derivation from another same-scope contract -- channel context mutation being ignored unless returned in `ChannelEvaluation` -- contract-specific handler matching with `HandlerMatchContext` -- programmatic untyped scalar events matching core primitive patterns -- existing processor-managed channels and embedded/triggered/lifecycle flows - -This gives the next project a stable base: implement repository-specific -contracts without changing the processor orchestration rules again. +The loader prefers an explicit handler channel and otherwise invokes +`deriveChannel(...)`. The result must identify a channel in the same effective +contracts map. Matching is read-only and runs against the frozen delivery +snapshot. Execution uses `ProcessorExecutionContext`, so patches, Root +emissions, internal events, termination requests, gas, and runtime child +ledgers remain under the processor's atomic run state. + +Runtime ledger submission is the exception to application-effect rollback: +`submitRuntimeGasLedger(...)` immediately admits one live-bounded named child +ledger to the invocation meter before buffered effects are applied. A later +failure discards patches, events, termination, markers, checkpoints, and +subscription changes, but reports that admitted gas and its ordered trace. + +`ContractMatchingService` supplies the shared frozen event-pattern matcher, +including identity, structural, schema, list, dictionary, primitive-scalar, +and provider-backed reference/type matching. + +## Execution order + +For a verified external occurrence the processor: + +1. revalidates the immutable occurrence and activation interval; +2. performs channel preselection and complete acceptance read-only; +3. freezes payload, checkpoint domain, checkpoint subject, Handler target, and + logical-delivery identity; +4. rejects stale delivery before initialization; +5. groups fresh accepted sources by same-scope logical-delivery identity and + validates target/payload agreement; +6. pre-admits matching target-handler bodies; +7. initializes the participating Root-to-target closure top-down; +8. executes each logical delivery once; +9. writes every participating source checkpoint only after complete success. + +The checkpoint subject is an exact node. A runtime-neutral ordered-stream +Channel can freeze an inline minimal `{stream, sequence}` subject and compare +`ChannelCheckpointContext.currentSubject()` with the exact prior +`lastEvent()` in `isNewerEvent(...)`. Their BlueIds are available from +`eventSignature()` and `lastEventSignature()`. The feeder `eventOrderKey` +orders occurrence activation; it is not a replacement for the source +Channel's own sequence-newness rule. Composite functions can delegate the +selected member's subject unchanged. + +Triggered and embedded-node events use the invocation-local deterministic +queue. Root emissions are appended to `ProcessResult.events` immediately and +also participate in local delivery. Non-Root emissions remain internal unless +Root explicitly emits them. + +## Changed subscription surface + +Before commit, `SubscriptionSurfaceValidator` compares affected branches of +the exact input and tentative Root and constructs a deterministic +`SubscriptionDelta`. Validation covers effective channels, embedded paths, +present child objects, ancestry cycles, portable limits, immutable +subscription functions, activation data, source contributions, and checkpoint +domains. Persistent index storage and feeder queries belong to the host, not +this repository. + +Hosts that persist Root revisions and the external subscription index should +use `processDocumentForPlatformCommit(...)`. It returns a +`PlatformProcessingResult` containing the ordinary semantic +`DocumentProcessingResult` and a separate `PlatformCommitCompanion`. The +companion binds the expected Root identity and revision, event identity and +order key, resulting revision, and the exact validator-produced +`SubscriptionDelta`. These values are committed together with compare-and-swap; +the companion is platform metadata, not a sixth `ProcessResult` field or a +public effect log. Rejected, stale, and already-terminated deliveries carry +progress-only companions and never carry a subscription delta. + +## Atomic failure behavior + +All patches, markers, checkpoints, events, termination requests, and +subscription changes are tentative. A deterministic runtime, evidence, +portable-limit, gas, or subscription-surface failure returns the exact input +Root and no Root events. Gas already admitted to the live invocation meter, +including a submitted runtime child ledger, remains in the total and ordered +trace. Runtime failure never commits a fatal marker or fatal lifecycle event. + +For the complete status matrix, diagnostic fields, detailed explanations of +portable-limit and subscription-surface failures, and host retry guidance, see +[Processor results, diagnostics, and recovery](processor-results-diagnostics-and-recovery.md). diff --git a/docs/processor-results-diagnostics-and-recovery.md b/docs/processor-results-diagnostics-and-recovery.md new file mode 100644 index 00000000..4ed75855 --- /dev/null +++ b/docs/processor-results-diagnostics-and-recovery.md @@ -0,0 +1,387 @@ +# Processor results, diagnostics, and recovery + +This guide explains how a host should interpret a completed Contracts 1.0 +`ProcessResult`, with particular attention to portable-limit and subscription- +surface failures.

Extensions may add stable details, but must not include stack +traces, exception class names, timestamps, cache state, transport data, or +locale-dependent text as machine-readable context. + +### Category vocabulary + +Status identifies the broad result boundary; category identifies the precise +reason. They are not one-to-one. For example, `runtime-fatal` can carry +`InvalidPatch`, `CheckpointPolicyError`, or `RuntimeExecutionFailure`, while +`subscription-surface-invalid` normally carries `SubscriptionSurfaceInvalid` +but may preserve a more precise underlying category. + +The exact current Java protocol vocabulary is the +[`ProcessorErrorCategory` enum](../blue-contracts-core/src/main/java/blue/language/processor/ProcessorErrorCategory.java): + +- input: `InvalidProcessingDocument`, `InvalidProcessingEvent`; +- runtime pointers, contracts, and patches: `InvalidRuntimePointer`, + `InvalidPatch`, `PatchBoundaryViolation`, + `ProtectedProcessorStateMutation`, `InvalidReservedRuntimeState`, + `UnsupportedRuntimeType`, `UnsupportedRuntimeRole`, `InvalidContractKey`, + `InvalidContractBinding`; +- evidence, routing, subscriptions, and checkpoints: + `InvalidExternalChannelSnapshot`, `ExternalSubscriptionLawViolation`, + `EmbeddedRouteNotFound`, `EmbeddedScopeNotObject`, `EmbeddedScopeCycle`, + `ActiveScopeCutOff`, `CheckpointDomainError`, `CheckpointPolicyError`, + `InconsistentLogicalDelivery`; +- values, schemas, generalization, and cyclic sets: `FixedValueConflict`, + `TypeCompatibilityViolation`, `SchemaViolation`, + `TypeGeneralizationFailure`, `CyclicSetMutationUnsupported`, + `CyclicMemberProcessingRootUnsupported`, + `CyclicMemberProcessingEventUnsupported`, + `CyclicSetEmbeddedBoundaryUnsupported`; +- portable limits and gas: `DirectNodeLimitExceeded`, + `MatchingDeliveryLimitExceeded`, `ParticipatingScopeLimitExceeded`, + `InternalEventLimitExceeded`, `PatchLimitExceeded`, + `RuntimeLedgerLimitExceeded`, `GasLimitExceeded`; +- general surface and runtime failures: `SubscriptionSurfaceInvalid`, + `RuntimeExecutionFailure`. + +Consumers should preserve the exact PascalCase value and must not derive a new +category from the diagnostic message or `limitName`. + +## Portable-limit failure + +### What it protects + +Portable limits are structural limits bound by the selected gas-manifest +package. They ensure that every implementation using that package can bound +individual collections, recursion, identity input, event queues, patches, and +runtime ledgers independently of CPU speed or memory size. + +Portable limits are different from gas: + +- gas is the accumulated weighted semantic work of the invocation; +- a portable limit bounds one exact dimension; +- an input may have gas remaining and still exceed a portable limit; +- increasing only the gas budget cannot repair a portable-limit failure. + +The exact names and values come from the +[bundled Contracts gas manifest](../blue-contracts-core/src/main/resources/blue/language/processor/contracts-gas-1.0.yaml). +It binds limits for contract-result patches and events, internal and Root event +queues, participating and embedded scopes, pointer and key sizes, direct +containers and identity input, type chains, cascade depth, and runtime-ledger +shape. These limits are ceilings, not promises that an input at the ceiling fits +under the gas budget. + +### Example + +For example, if the bound manifest allows 1,024 patches per contract result and +one Handler attempts to return 1,025: + +```text +status = portable-limit-exceeded + +diagnostic = { + category = PatchLimitExceeded + message = "Portable limit exceeded: patchesPerContractExecutionResult" + details = { + limitName = "patchesPerContractExecutionResult" + observed = "1025" + limit = "1024" + } +} +``` + +The category identifies the limit family, while `limitName` identifies the +exact manifest boundary. Public limit-family categories include: + +- `DirectNodeLimitExceeded`; +- `MatchingDeliveryLimitExceeded`; +- `ParticipatingScopeLimitExceeded`; +- `InternalEventLimitExceeded`; +- `PatchLimitExceeded`; +- `RuntimeLedgerLimitExceeded`. + +Several concrete manifest limits can share one family category. Hosts should +therefore retain both `category` and `details.limitName`. + +A portable limit known during admission can fail with zero gas. A limit reached +after semantic execution begins reports the gas admitted before the failed +check. In either case the rejected observation is not partially accepted. + +### Recovery + +Repeating the same Root, event, evidence, registry, and limit manifest produces +the same failure. A host should not blindly retry it. Recovery requires one of: + +- reducing or partitioning the document, event, emitted effects, or embedded + scope structure; +- changing the responsible contract or runtime behavior; +- adopting a different limit only as part of a compatible, identity-bound + protocol manifest. + +Changing cache size, worker memory, thread count, or the ordinary gas budget is +not a portable fix. + +## Subscription-surface failure + +### What the surface represents + +The external subscription surface is the finite set of External Channel +occurrences the managing feeder must observe for one Root revision, including +occurrences in transitively declared Process Embedded scopes. + +One occurrence carries deterministic indexing and revalidation information, +including: + +```text +scopePath +channelKey +ordered source-contribution BlueIds +effective type BlueId +channel order +subscription keys +checkpoint domain +same-scope dependency snapshot +activation and retirement bounds +``` + +Without this surface the feeder cannot know which external sources and keys to +observe, or prove that a later delivery belongs to the same Root revision. + +### Pre-commit validation + +The processor can reject an invalid input surface during preflight or while +recognizing a changed embedded closure. After successful Handler execution, all +state is still tentative, and the same failure boundary protects final +before/after validation. If changed paths can affect subscriptions, the +`SubscriptionSurfaceValidator` derives the affected surface before and after +the tentative change: + +```text +before = SUBSCRIPTION_SURFACE(input Root) +after = SUBSCRIPTION_SURFACE(tentative Root) + +removed = before - after +added = after - before +``` + +The resulting `SubscriptionDelta` is canonically ordered. A platform commit +must atomically install the new Root revision, Root outbox, subscription delta, +activation or retirement intervals, and delivery progress. A failure in +surface derivation therefore rejects the entire tentative invocation. + +### What makes a surface invalid + +The validator fails closed when it cannot derive one finite, unambiguous, +deterministic index. Examples include: + +- an External Channel returns no subscription-key set, an empty set, duplicate + keys, null keys, or more keys than the manifest permits; +- the same immutable subscription function produces different output or gas + trace when evaluated again; +- a Process Embedded path is malformed, duplicated, cyclic, ambiguous, or + selects a non-object child; +- embedded ancestry revisits the same exact node; +- more than one effective Process Embedded contract exists in one scope; +- the effective `contracts` value is not a direct object map; +- two entries create the same external-subscription occurrence; +- effective Channel content, source contributions, dependencies, activation + data, or checkpoint-domain identity cannot be established; +- the committing Root revision would overflow. + +For example, a Channel returning duplicate keys: + +```text +channelKeys(snapshot) -> ["customer/42", "customer/42"] +``` + +produces a result shaped like: + +```text +status = subscription-surface-invalid + +diagnostic = { + category = SubscriptionSurfaceInvalid + message = "Subscription keys must be unique non-empty Text" + details = { + scopePath = "/" + contractKey = "" + } +} +``` + +`scopePath` and `contractKey` are optional because some failures concern the +whole Root. When a more precise deterministic failure caused surface +validation, its category may be preserved instead of the general +`SubscriptionSurfaceInvalid` category. + +### Portable limits at this boundary + +The two statuses describe different failure boundaries: + +- `portable-limit-exceeded` means an explicit portable size or cardinality + guard rejected work; +- `subscription-surface-invalid` means the Root cannot produce a valid + subscription index. + +A generic portable guard reached during surface processing still produces +`portable-limit-exceeded`. A surface rule such as duplicate keys, ambiguous +routes, nondeterministic subscription functions, or a surface-specific +cardinality violation produces `subscription-surface-invalid`. + +### Recovery + +More gas does not repair an invalid subscription surface. The Root or runtime +must be changed so every active External Channel has deterministic finite keys, +valid embedded ancestry, exact dependency evidence, and one canonical +checkpoint domain. + +Hosts should use `processDocumentForPlatformCommit(...)` when they persist Root +revisions and the external subscription index. Its `PlatformCommitCompanion` +binds the exact input revision and validated `SubscriptionDelta` required for +the atomic compare-and-swap. Only committing success carries the validated +delta. A validated noncommitting semantic result can carry a progress-only +companion, but never a new Root, Root outbox, or non-empty subscription delta. +If the compare-and-swap fails because the authoritative Root changed, the host +records nothing and recomputes against the new revision. + +## Failure, suspension, and retry + +Resource unavailability is not a diagnostic status. `PROCESS_ATTEMPT` returns: + +```text +Complete(ProcessResult) +or +NeedsResources(sortedExactBlueIds) +``` + +For `NeedsResources`, the host acquires and verifies the named exact nodes +outside deterministic execution, then retries from the exact same Root and +event. Suspension commits no Root, events, progress, or portable gas. The +ordinary `processDocument(...)` API propagates +`ExecutionEvidenceUnavailableException`; `processAttempt(...)` converts it to +`NeedsResources` only when the missing resources can be represented by exact +BlueIds. Unavailability without such an exact demand remains a host exception. + +By contrast, portable-limit failure, subscription-surface failure, gas +exhaustion, capability failure, runtime failure, and deterministic invalid +inputs are completed terminal results for that exact Root revision. A platform +should record their terminal progress using compare-and-swap and should +quarantine or explicitly administer a deterministic poison event rather than +retrying it without a change. + +The ordinary `processDocument(...)` API converts deterministic invalid delivery +evidence to an `invalid-processing-document` result. The +`processDocumentForPlatformCommit(...)` boundary instead throws +`InvalidExecutionEvidenceException`: untrusted evidence cannot produce a +trustworthy compare-and-swap companion or progress record. + +Programming and lifecycle errors such as null arguments, a closed processor, or +initializing an already initialized document are Java exceptions, not completed +`ProcessResult` diagnostics. + +## Cross-language determinism checklist + +Java, JavaScript, and other implementations agree when they use the same: + +- graph-equivalent Root and event; +- verified revision-bound delivery evidence; +- runtime registry identity and deterministic runtime behavior; +- gas manifest, gas budget, and portable-limit manifest; +- normative phase ordering and failure precedence. + +Cross-language conformance compares: + +- status wire value; +- diagnostic category; +- relevant structured details such as scope, key, path, and numeric limit; +- resulting Root BlueId; +- ordered Root event BlueIds; +- total gas; +- when using the separate debug or conformance API, the exact out-of-band gas + trace. + +Diagnostic prose is informative and may differ. Do not compare `message`, +serialized map-key order, stack traces, physical fetch counts, cache hits, or +allocation behavior. JavaScript implementations must preserve exact integer +semantics for gas and limit observations and must not rely on ordinary object +enumeration when the Contracts algorithm requires canonical Unicode code-point +ordering. diff --git a/docs/reference/conformance-fixtures.md b/docs/reference/conformance-fixtures.md new file mode 100644 index 00000000..4551477a --- /dev/null +++ b/docs/reference/conformance-fixtures.md @@ -0,0 +1,66 @@ +# Conformance fixture coverage + + + +Schema: `blue-language-java-generated-documentation/1.0`. + +Release package: `blue-language-contracts-embedded-modules-collection-paths` + +Package identity: `sha256:0268c0adc8badf0d1ab5cdef4a323117b82253a3695f9125af750437a23014b6` + +| Suite | Fixture count | +| --- | ---: | +| `contracts` | 154 | +| `language` | 153 | + +## Package identities + +| Input | Identity | +| --- | --- | +| `languageRegistry` | `sha256:b705171a6ca62c990792bcb78db9d921caf5b0ed06370648b9a81769d69dd71e` | +| `languageFixtures` | `sha256:44465973c5c5a8c1e60712fc7970236015d9500e2e9e3fc904e364552ec74a55` | +| `contractsRegistry` | `sha256:46a7744c1cbfa4b00e1d8a99f6ca3f0089ef697de968fee08547894ab02b0ca1` | +| `contractsGas` | `sha256:88c7bbe77d531c9e973cae13002c3464a2c14568833adf5d804d13b7b3d26af5` | +| `contractsFixtures` | `sha256:16392301655431695df6a7cc142a7e388e426c382bf4e3c5f06ddfafb8efecdc` | + +## Specification hashes + +| Specification | SHA-256 | +| --- | --- | +| `languageSha256` | `a234b0b42190a7982809781b5efdaa2e5f1ab4b7f8d870fbd1ffe7020cc7e869` | +| `contractsSha256` | `6406153791ed99cf97163726b8d2a272e3f0ca1078dc6c9f69b81855d81e5c81` | + +## Category coverage + +| Suite and category | Fixtures | +| --- | ---: | +| `contracts:chk` | 7 | +| `contracts:disc` | 6 | +| `contracts:e2e` | 3 | +| `contracts:emb` | 21 | +| `contracts:evt` | 5 | +| `contracts:fail` | 5 | +| `contracts:feed` | 18 | +| `contracts:gas` | 58 | +| `contracts:idx` | 2 | +| `contracts:init` | 6 | +| `contracts:life` | 4 | +| `contracts:prot` | 2 | +| `contracts:rep` | 7 | +| `contracts:snd` | 7 | +| `contracts:upd` | 3 | +| `language:BlueId` | 32 | +| `language:Canonicalization` | 12 | +| `language:Circular` | 5 | +| `language:CircularReferences` | 1 | +| `language:DocumentationLint` | 1 | +| `language:LimitedExpansion` | 4 | +| `language:LimitedResolution` | 7 | +| `language:Matching` | 1 | +| `language:MetaConformance` | 1 | +| `language:Minimization` | 3 | +| `language:Provider` | 18 | +| `language:Registry` | 7 | +| `language:Resolution` | 47 | +| `language:Schema` | 13 | +| `language:Specialization` | 1 | diff --git a/docs/reference/gas-counters.md b/docs/reference/gas-counters.md new file mode 100644 index 00000000..8e9fb356 --- /dev/null +++ b/docs/reference/gas-counters.md @@ -0,0 +1,84 @@ +# Contracts gas counter catalog + + + +Schema: `blue-language-java-generated-documentation/1.0`. + +The schedule is semantic release input.

It is intentionally runtime-neutral. Follow the links at +the end when you need exact Java APIs, provider implementation details, or +release procedures. + +## 1. Values and nodes + +Blue uses the JSON value model: text, integer, finite double, boolean, list, +and object. Java represents an authored or transported value as a mutable +`Node`. + +```yaml +name: Greeting +value: hello +``` + +`name`, `description`, `type`, and `schema` are Blue metadata. Other object +keys are ordinary properties. A node has at most one payload shape: scalar, +list, or object. + +The mutable Java object is not the semantic identity. Runtime operations copy +or freeze it, and returned mutable nodes belong to the caller. + +## 2. Blue is a graph, not a tree + +A pure reference contains only a BlueId: + +```yaml +blueId: 7i7D...exactBase58Value +``` + +That edge can point to content used in many places. References, shared types, +and finalized cyclic sets make the logical value a graph. A YAML or JSON +document is only one slice or representation of that graph. + +```text +document slice --pure reference--> exact node + | ^ + +----------another edge-------+ +``` + +Provider calls and physical fragments retrieve graph evidence. They do not +create a second value model. + +## 3. One BlueId and pure references + +Blue has one BlueId format and algorithm. There are two preparation paths: + +```text +exact node --------------------------------------> direct BlueId + +Source -> preprocess -> resolve -> canonicalize -> direct BlueId +``` + +The first path accepts exact identity input. The second accepts human-friendly +Source and produces exact canonical input before running the same final +calculation. “Content BlueId” is shorthand for this identifier, not another +kind of ID. + +A BlueId is about identity, not storage. It does not say where bytes live, +whether a provider is online, whether a value is cached, or which fragment +contains it. + +## 4. Types and specialization + +A type is an ordinary exact Blue node referenced by BlueId. An instance can +use a pure type reference: + +```yaml +type: + blueId: 4abc...personType +name: Ada +``` + +Resolution combines type-derived values and local values under the Language +merge rules. Specialization is a construction operation: it combines a type +and overlay to create a new node. It may therefore create a new BlueId. + +Expansion is different. It replaces references with exact content while +preserving the same node and BlueId. Keep this distinction: + +```text +expand = same node, more materialized representation +specialize = new node constructed from type plus overlay +``` + +## 5. Expansion and collapse + +Suppose a child is stored separately: + +```yaml +child: + blueId: 9xyz...child +``` + +Expansion verifies and inserts the referenced exact child. Collapse replaces +an eligible exact subtree with its pure reference. Both preserve the enclosing +identity. + +```mermaid +flowchart LR + R["pure reference edge"] -->|"expand with verified evidence"| I["inline exact child"] + I -->|"collapse"| R +``` + +Strict expansion requires complete evidence. A limited operation reports an +exhaustive outcome; it never treats an unavailable provider as proof of +absence. + +## 6. The `blue` preprocessing directive + +Source may carry one root `blue` directive containing imports and ordered +transformations: + +```yaml +blue: + imports: + Message: + blueId: 8msg...textType + transformations: + - type: + blueId: 2first...transform + - type: + blueId: 3second...transform +type: Message +value: hello +``` + +The order is exact: + +1. resolve and validate the directive, imports, and transformations; +2. remove `blue` from a cloned Source; +3. run transformations once in declaration order; +4. run baseline wrapper normalization, alias substitution, primitive + inference, and final validation. + +All preflight completes before the first transformation. The baseline is a +mandatory algorithm stage, not an implicit directive. + +## 7. Resolution establishes complete meaning + +Resolution follows verified types and references, then applies merge and +schema rules. It answers “what is the complete value?” + +```yaml +# type contributes +enabled: true +items: [A, B] + +# instance contributes +items: [C] + +# resolved meaning +enabled: true +items: [A, B, C] +``` + +Complete resolution can establish semantic absence. A transport miss or an +exhausted traversal budget alone cannot. + +## 8. Canonicalization versus minimization + +Canonicalization answers “what unique exact value is hashed?” Minimization +answers “what compact ordinary Source resolves to the same meaning?” + +For an object, canonicalization materializes identity-bearing inherited data; +minimization may omit data already supplied by the type. For an append-only +list: + +```text +Inherited [A, B] +Resolved [A, B, C] +Minimized $previous(id([A, B])) + C +Canonical [A, B, C] +``` + +Source Document BlueId uses canonicalization, not minimization. A minimized +overlay is Source and must be processed again before direct calculation. + +## 9. List identity and incremental work + +List identity is one domain-separated recursive prefix fold. Here `H` is the +normal direct BlueId hash over RFC 8785 canonical JSON, and `id(elementN)` is +the exact BlueId of that element: + +```text +L0 = H({"$list":"empty"}) +Ln = H({"$listCons":{ + "elem":{"blueId":id(elementN)}, + "prev":{"blueId":Ln-1} + }}) +id([a1, ..., an]) = Ln +``` + +RFC 8785 serializes the fold map as `elem` before `prev`; neither Java map +insertion order nor another host language's object order is semantic. + +If the BlueId for `[A, B]` is established, appending `C` performs one fold +step with that prefix identity and `id(C)`. It does not need the bodies of A or +B. This makes append work O(delta). + +Editing an earlier element keeps the accumulator immediately before the edit, +then recomputes that element and every following suffix step. Identity does not +imply that the earlier bodies are stored together. + +## 10. Schemas and unconstrained fields + +These declarations mean different things: + +```yaml +# no type: any Blue value is allowed +payload: + description: Runtime-defined payload +``` + +```yaml +# Dictionary: an object value is required +payload: + type: Dictionary +``` + +```yaml +# required but otherwise unconstrained +schema: + required: [payload] +payload: + description: Must exist; its value shape is open +``` + +No type is not the same as Dictionary. `required` controls presence, not the +shape of an unconstrained value. + +## 11. Providers and immutable snapshots + +A typed provider outcome distinguishes: + +- `FOUND`: candidate evidence is available; +- `NOT_FOUND`: the provider definitively has none; +- `UNAVAILABLE`: the answer cannot currently be established; +- `INVALID_EVIDENCE`: content or proof failed verification. + +The Language boundary verifies identity, Source environment, fragments, and +cyclic proofs before admitting a value. A `ResolvedSnapshot` retains immutable +canonical and resolved roots. Mutable accessors return detached copies. + +Snapshots let matching, patching, and Contracts reuse established evidence +without making cache state semantic. Warm and cold executions must agree. + +## 12. Contracts expresses deterministic time and change + +Language establishes meaning and identity. Contracts adds a deterministic +state transition: + +```text +PROCESS(Root, event) -> status, Root, Root events, gas, diagnostic? +``` + +The event is the proposed occurrence of time/change. Contracts in Root decide +whether to accept it and which patches or events to produce. Only `success` +commits. Every other completed status returns the exact input Root and no Root +events. + +## 13. Feeder versus processor + +The feeder watches the finite external subscription surface, obtains external +events, orders candidate occurrences, and supplies exact delivery evidence. +The processor remains the semantic authority: + +```text +feeder selects and orders +processor preflights the participating closure +selected executable body loads +patches rebuild the changed spine +internal events drain +Root events are returned +Root/checkpoints/lifecycle commit atomically +``` + +Feeder indexes and transport progress are platform state. They do not become a +third authored input to `PROCESS`. + +An indexed host can make that boundary explicit. It first asks the public +indexed-delivery evaluator to verify the complete retained interval surface and +the ordered physical candidate set. It then passes the resulting exact plan, +together with one request-local provider, through +`PlatformProcessInvocation` to `BlueContracts.processForPlatformCommit(...)`. + +```text +semantic inputs: Root + event +execution environment: exact verified plan + invocation provider +host result: PROCESS result + atomic commit companion +``` + +Contracts binds the plan back to the exact Root BlueId, event BlueId, managed +and indexed revision, event order, and immutable runtime-registry generation. +It also replays the complete supplied plan through the authoritative verifier. +Supplying a prepared plan avoids acquiring the same environmental state again; +it never turns that plan into trusted semantic input and never bypasses +verification. + +The invocation provider is the complete provider graph for that attempt. It is +used for Root/event admission, selected embedded scopes, contract and type +chains, selected Channel and Handler content, patch opening, and final +subscription validation. Language verifies its returned nodes but does not add +the service provider, bootstrap provider, or a prior invocation's cache as a +fallback. The caller composes any intended fallback explicitly. Closing the +invocation releases only invocation-owned state and never closes that borrowed +provider. + +## 14. One Root and embedded scopes + +An embedded scope is an owned object path declared by an effective Process +Embedded contract. It is not an independent document or commit. + +```yaml +name: Root +counter: 0 +child: + counter: 0 +contracts: + embedded: + type: Process Embedded + paths: [/child] +``` + +The two declaration forms have deliberately different meanings: + +```text +paths: one exact child scope per normalized pointer +collectionPaths: every present direct stable-key object member is a child scope +``` + +For example, `collectionPaths: [/lessons]` selects +`/lessons/lesson-a` and `/lessons/lesson-b`; it does not select the +`/lessons` container. There are no wildcards, implicit List items, +`/contracts/...` scopes, or inherited parent Channels. Each selected child +must carry its own exact local bindings. The same exact child or Channel +BlueId can be reused at two keys, but the keys name independent owned +occurrences. + +The participating closure is frozen before mutation. Child work may run in a +deterministic order, but all patches apply to one tentative Root. If an active +scope occurrence is replaced or removed, that occurrence and its descendants +are cut off. + +A member created during an event is therefore not processed by that event. A +successful commit publishes a subscription delta whose lower boundary is the +creating event; the new member can receive the next eligible event. Replacing +a parent Channel does not rewrite existing children, while a later-created +child may explicitly reuse the new exact Channel value. Concrete targeting is +still defined by the selected Channel runtime, not by `collectionPaths`. + +Internal child events are drained inside the invocation. Only events emitted +by Root are returned to the caller. + +## 15. Channels and handlers + +An External Channel is a source of accepted external occurrences. Its event +may select a different same-scope target Channel for handler matching: + +```text +source Channel "inbox" accepts event +event selects target Channel "orders" +handlers bound to "orders" match and execute once +source "inbox" remains checkpoint owner +``` + +Source classification, target selection, handler matching, and checkpoint +ownership are distinct immutable decisions. A target is not evaluated as an +external source unless it independently participates as one. + +## 16. Gas and representation invariance + +Portable gas is the ordered, named trace of semantic work. A child runtime +opens a named ledger, charges manifest-bound counters, and merges it once into +the invocation budget. + +```mermaid +flowchart TB + Parent["processor gas ledger"] --> Language["Language semantic counters"] + Parent --> Phases["processor phase counters"] + Parent --> Child["runtime child ledger"] + Child --> Merge["submit exactly once"] +``` + +Provider calls, bytes, cache hits, timings, and threads are host metrics, never +portable gas. Inline/reference, warm/cold, fragmented/whole, and batched/ +unbatched forms must produce the same semantic demand and gas trace. + +Portable limits are different from gas. They bound one structural dimension. +More gas cannot repair a portable-limit failure. + +## Where to go next + +- [Nodes, graphs, and BlueIds](guides/nodes-graphs-and-blueids.md) +- [Preprocessing and the `blue` directive](guides/preprocessing-and-blue-directive.md) +- [Resolve, canonicalize, and minimize](guides/expand-collapse-resolve-canonicalize-minimize.md) +- [Providers and evidence](guides/providers-and-evidence.md) +- [Runtime projection and indexed delivery](guides/runtime-projection-and-indexed-delivery.md) +- [Contracts processing](guides/contracts-processing.md) +- [Embedded collection paths](guides/embedded-collection-paths.md) +- [Collection-paths migration report](collection-paths-and-cohesion-migration-report.md) +- [Platform invocation and pure-reference correction report](platform-invocation-and-pure-reference-release-report.md) +- [Statuses and diagnostics](reference/statuses-and-diagnostics.md) +- [Architecture overview](architecture/overview.md) +- [Developer process](developer-process.md) + +Runnable Java versions of the examples live in `:examples` and are executed by +its test suite.

Processor Specification 1.0 - -> **Positioning.** Blue contracts are Blue's form of **smart contracts**: deterministic, content-addressed runtime declarations attached to Blue documents. They react to events, invoke supported channel and handler implementations, and update document state only through the processor rules defined by this specification. Unlike blockchain-specific smart contracts, Blue contracts do not imply any particular consensus protocol, ledger, account model, token model, authorization system, network transport, or persistence layer. - -> **Scope.** This document defines Blue runtime contract processing: contracts, channels, handlers, markers, active scopes, embedded document processing, lifecycle events, JSON patch execution, update cascades, event FIFOs, embedded-event bridging, checkpoints, termination, gas accounting, and processor conformance. It does **not** define the Blue content language, BlueId, type resolution, schema, canonicalization, expansion, or minimization. Those are defined by the separate **Blue Language Specification 1.0**. - -Where this document references runtime types such as **Contract**, **Channel**, **Handler**, **Marker**, **Document Update Channel**, **Triggered Event Channel**, **Lifecycle Event Channel**, **Embedded Node Channel**, **Process Embedded**, **Channel Event Checkpoint**, **Type Generalization Policy**, **Type Generalization Rule**, and processor-emitted events, their canonical type definitions and canonical BlueIds are supplied by the canonical Blue runtime type registry. - -Appendix A defines the normative runtime semantics of those core runtime types and shows their intended registry source nodes. The canonical registry is the authority for exact node content and BlueIds. - -Canonical runtime type nodes are identity-bearing Blue content. Their `description` fields define runtime semantics and affect BlueId. Editing a canonical runtime description changes the runtime type identity and therefore must be treated as a registry/versioning change, not as ordinary documentation editing. - -## Conventions - -The key words **MUST**, **MUST NOT**, **REQUIRED**, **SHOULD**, **SHOULD NOT**, **MAY**, and **OPTIONAL** are to be interpreted as normative requirement levels. - -Sections marked **normative** define required behavior for conforming Blue Contracts and Processor 1.0 implementations. Sections marked **informative** explain intent, examples, or implementation guidance. - -The term **Blue Language** means Blue Language Specification 1.0 unless another version is explicitly named. - ---- - -## 0. Overview - -Blue contracts are smart contracts for Blue documents: they make a Blue document executable in a deterministic, content-addressed way. - -A processor is a deterministic state-transition function: - -```text -PROCESS(document, event) -> (new_doc, triggered_events, total_gas) -``` - -- **document** is a Blue processing document: a valid Blue document after Blue Language preprocessing, suitable for runtime interpretation. -- **event** is a Blue node delivered by an external feeder or by a calling environment. -- **new_doc** is the updated document after all processing performed by this invocation. -- **triggered_events** is the root-scope outbox for this invocation, including root-scope triggered events and root lifecycle events, whether or not they were handled locally. -- **total_gas** is a deterministic tally of abstract gas units consumed during the invocation. - -Contracts live under a node's `contracts` map. They are ordinary Blue content for identity purposes, but a Blue processor gives supported contract types runtime meaning. - -A processor run is organized around **active scopes**. The root document is always an active scope. Additional active scopes are declared by a scope's **Process Embedded** marker. Each active scope has its own local contracts, lifecycle, checkpoint, triggered-event FIFO, and termination state. - -Runtime execution follows this shape: - -```text -PROCESS(root, event) - -> process embedded child scopes first - -> initialize this scope if needed - -> match channels for the incoming event - -> run handlers in deterministic order - -> apply patches immediately - -> after every patch, deliver Document Update cascades bottom-up - -> bridge child emissions to the parent - -> drain this scope's Triggered FIFO exactly once - -> return updated document, root outbox, total gas -``` - -Several separations are fundamental: - -| Boundary | Meaning | -|---|---| -| **Language vs processor** | The Blue Language parses, resolves, canonicalizes, and hashes content. The processor executes supported contracts. | -| **Feeder vs processor** | The feeder collects and orders external events. The processor deterministically handles one delivered event. | -| **Scope vs embedded child** | A parent may add, replace, or remove an embedded child root, but may not patch inside the child's embedded domain. | -| **Effect buffering vs application** | Handlers and supported channels may request patches, emissions, gas, and termination during execution, but those requests are buffered and applied only through the normalized result order. | -| **Patch vs Direct Write** | Handler/channel patches cause Document Update cascades. Processor Direct Writes update reserved runtime state without cascades. | -| **Capability failure vs runtime fatal** | Unsupported contract capabilities detected before execution produce no mutation. Deterministic errors during a run terminate a scope. | - -This specification is intentionally deterministic. Contract execution MUST NOT depend on wall-clock time, CPU speed, random sources, network latency, operating-system scheduling, or hidden mutable state. - ---- - -## 1. Scope, Goals, Versioning, and Conformance - -### 1.1 Goal - -Blue Contracts and Processor 1.0 defines a deterministic processor model for Blue documents with: - -- scope-local contracts; -- deterministic channel and handler ordering; -- explicit, isolated document mutation through JSON-patch entries; -- immediate bottom-up Document Update cascades after every successful patch; -- per-scope Triggered FIFOs with exactly one drain per scope per invocation; -- embedded child scopes and parent-side event bridging; -- first-run initialization lifecycle; -- channel checkpoints for external-event idempotency; -- graceful and fatal termination semantics; -- deterministic gas accounting. - -### 1.2 Out of scope - -The following are not defined by this specification: - -- external event collection, consensus, scheduling, delivery guarantees, or retries; -- authorization, authentication, signatures, encryption, or access-control policy; -- network, storage, or provider protocols; -- user-interface semantics; -- contract programming languages or bytecode formats; -- non-deterministic operations such as timers, random numbers, ambient clocks, or network reads inside handlers; -- Blue Language content identity and BlueId algorithms. - -A profile MAY define contract languages, authorization, signing, or deployment protocols, but those profiles MUST preserve the deterministic observable behavior defined here. - -### 1.3 Versioning - -This document defines **Blue Contracts and Processor 1.0**. - -A runtime contract type is identified by its BlueId in the canonical Blue runtime type registry. A processor MUST declare which Blue Contracts and Processor version it implements and which external contract type BlueIds it supports. - -Blue Contracts 1.x revisions MUST preserve the observable behavior of valid Blue Contracts 1.0 documents. Any incompatible change to event ordering, patch semantics, termination semantics, gas formulas, or processor-managed type semantics requires a new major processor version. - -### 1.4 Conformance - -A conforming Blue Contracts and Processor 1.0 implementation MUST implement all normative requirements in this specification. - -A conforming processor MUST support: - -- root-scope processing; -- active embedded scopes declared by **Process Embedded**; -- all processor-managed channel families in §5; -- all required runtime markers in Appendix A; -- deterministic contract discovery and must-understand capability checks; -- deterministic sorting by `(order, key)`; -- patch application and Document Update cascades; -- post-patch type soundness validation and dynamic type generalization; -- Triggered FIFO behavior; -- embedded-event bridging; -- lifecycle delivery; -- checkpoint lazy creation and update for external channels; -- termination semantics; -- gas accounting formulas; -- the Blue Contracts 1.0 conformance suite. - -A tool that implements only a subset may be useful, but it MUST NOT describe itself as a conforming Blue Contracts and Processor 1.0 implementation. - -### 1.5 Runtime registry dependency - -The canonical Blue runtime type registry is part of the Blue Contracts 1.0 release surface. Its entries for processor-managed contracts and events are content-addressed and versioned with this specification. - -A conforming processor MUST use the registry BlueIds for runtime contract type recognition. A different registry binding does not produce portable Blue Contracts 1.0 behavior. - -Canonical runtime registry nodes are self-describing Blue content. - -A runtime registry node's `name` and `description` fields are identity-bearing content under the Blue Language. A canonical runtime registry entry SHOULD include a concise normative `description` that defines the semantics of the runtime type. Changing that semantic description changes the node's BlueId and therefore defines a different runtime type. - -Non-normative examples, rationale, translations, tutorial material, implementation notes, and editorial commentary MUST NOT be included in canonical runtime registry nodes unless intentionally made identity-bearing. Such material belongs in the prose specification, registry documentation, or examples outside the canonical node. - -The registry file is the authority for exact string content of canonical runtime nodes. Code blocks in this specification should be generated from, or kept equivalent to, the registry entries used to calculate the published BlueIds. - -The canonical runtime registry entry for each processor-managed type MUST include: - -- the exact registry source node; -- the exact preprocessed/canonical node used for BlueId calculation, or a deterministic rule for producing it; -- the node's calculated BlueId; -- the Blue Contracts and Processor version that publishes it; -- the conformance fixture package identity that verifies it. - -A conforming processor MUST verify, at release or test time, that every bundled runtime type node hashes to the published registry BlueId. - -Canonical runtime registry source nodes MUST be reproducible under one of these release-defined modes: - -1. all cross-references are exact `blueId` references in the registry source; or -2. the registry manifest defines the exact preprocessing environment used to replace both Blue Language core aliases and Blue runtime registry aliases. - -A runtime registry release MUST publish enough information for an independent implementation to calculate every runtime type BlueId from the registry source nodes. Implementations MUST NOT rely on implementation-local alias maps to reproduce runtime registry BlueIds. - ---- - -## 2. Runtime Document Model and Processing Inputs - -### 2.1 Processing Document (normative) - -The normative `PROCESS` function operates on a **Processing Document**: a Blue Language Preprocessed Document used as the mutable **Selected Document View**. The document MUST NOT contain the root `blue` preprocessing directive or unresolved authoring aliases. - -A Processing Document is not required to be a fully Resolved View before `PROCESS` begins. Contract entries are resolved on demand during contract discovery and execution, using the resolved contract views required by §2.5. - -A Blue document whose root is not an object is valid Blue content, but it is not a processable Blue Contracts document under this specification because the root active scope is an object scope. A conforming `PROCESS` implementation MUST reject such input as an invalid Processing Document before runtime begins, with no mutation, no lifecycle events, and zero gas. - -A higher-level API MAY accept Blue Source Documents and apply Blue Language preprocessing before invoking `PROCESS`. Such preprocessing is outside the runtime run: - -- it consumes no gas under this specification; -- it does not emit lifecycle events; -- it does not trigger Document Update cascades; -- it is not a handler/channel mutation. - -### 2.2 Event input (normative) - -The normative `PROCESS(document, event)` function receives a **Processing Event**: a Blue node after Blue Language preprocessing. It MUST NOT contain a root `blue` directive or unresolved authoring aliases. - -The input `event` is not wrapped in a processor envelope by this specification. - -The processor MUST treat the input event as read-only. External channels may adapt it into channelized payloads for handlers, but the original event node is the event stored in channel checkpoints unless a concrete channel type explicitly defines a different checkpoint subject. - -A higher-level API MAY accept Source-event syntax and preprocess it before calling `PROCESS`. This preprocessing is outside the runtime run, consumes no gas, and emits no lifecycle or Triggered events. - -### 2.3 Runtime views (normative) - -A processor may use different internal views of the same document: - -| View | Purpose | -|---|---| -| **Selected Document View** | The mutable document tree patched by runtime operations. | -| **Resolved Contract View** | The Blue Language resolved view of contract entries, used to identify supported contract types and effective fields. | -| **Snapshot View** | A read-only snapshot used in Document Update `before` and `after` payloads. | - -Only the selected document view is mutated. Contract resolution, provider expansion, and type-materialization are view operations unless explicitly represented by a patch or Direct Write. - -### 2.4 Scopes (normative) - -A **scope** is an absolute runtime pointer to an object node in the selected document. The root scope is `/`. - -An active scope is either: - -- the root scope `/`; or -- a child root declared by the nearest active ancestor's **Process Embedded** marker and processed by the algorithm in §7. - -Contracts are scope-local. A contract under one scope's `contracts` map is not inherited by parent scopes, child scopes, embedded scopes, or referenced nodes. - -A `contracts` map on a node that is not an active scope is ordinary Blue content and is not executed during this processor invocation. - -### 2.5 Contract discovery and type recognition (normative) - -When a processor is about to execute a scope, it MUST discover the scope's `contracts` map, if present, and perform **Contract Recognition Resolution** for each contract entry. - -Contract Recognition Resolution MUST resolve the contract entry's effective type chain far enough to identify: - -- the effective contract type BlueId; -- whether the effective type is a subtype of **Contract**, **Channel**, **Handler**, or **Marker**; -- processor-relevant effective fields such as `order`, `channel`, `event`, `path`, `childPath`, `paths`, `lastEvents`, `cause`, `reason`, and any fields required by the concrete supported contract type. - -Contract Recognition Resolution MUST use Blue Language provider verification for referenced type content. The resolved contract entry and all consulted effective fields MUST be valid under Blue Language resolution and schema rules. - -A processor MUST NOT resolve unrelated document subtrees merely for discovery, and MUST NOT execute contracts during discovery. - -If a supported concrete contract type requires additional fields to decide acceptance, matching, or processor behavior, those fields are part of that contract type's required recognition view. - -If a contract entry's type cannot be resolved because required provider content is unavailable or fails BlueId verification, the scope MUST enter fatal termination unless the failure is detected during the pre-execution capability check in §2.6. - -A contract entry whose effective type is not a subtype of **Contract** is inert content unless it appears under a processor-reserved key. If it appears under a processor-reserved key, it is incompatible and causes runtime fatal termination (§3.6, §11.2). - -### 2.5.1 Runtime Contract Discovery View (normative) - -Blue Contracts 1.0 discovers runtime contracts from the selected document's materialized scope-local `contracts` map only. - -A contract entry is runtime-discoverable only when it is present as a materialized entry under `JOIN_SCOPE_PATH(scope, "/contracts/")` in the Selected Document View at the point of discovery. Contract entries that would appear only by resolving the scope node's own type chain are Blue Language content, but they are not executed by the Blue Contracts 1.0 core runtime unless they have been materialized into the Selected Document View by preprocessing, by an explicit runtime patch, or by a profile that explicitly extends this rule. - -Once a materialized contract entry is discovered, the entry itself is resolved using Contract Recognition Resolution (§2.5) to determine its effective contract type BlueId and processor-relevant effective fields. - -Processor-managed runtime markers at reserved keys are always selected-document state. They MUST NOT be inherited from a scope type. If Contract Recognition Resolution would expose a type-derived reserved processor marker that is not materialized in the Selected Document View, the processor ignores it for runtime state. If such a marker is materialized under a non-reserved key, §3.6 duplicate/incorrect-key rules apply. - -### 2.6 Must-understand capability check (normative) - -Before mutating the document or delivering lifecycle events, a processor MUST perform a must-understand check for the contract entries that are in the initial active processing closure. - -The initial active processing closure consists of: - -1. the root scope; -2. embedded object scopes reachable by reading **Process Embedded** markers from existing scopes before any runtime patches have been applied. - -The initial active processing closure excludes: - -- missing embedded child paths; -- non-object child roots, which are invalid embedded scopes if selected during runtime traversal; -- scopes with a valid pre-existing **Processing Terminated Marker**, except that the terminated marker itself MUST be recognizable enough to prove the scope is inactive. - -Unsupported contracts inside a pre-existing terminated inactive scope do not cause must-understand failure because that scope is not active for this invocation. - -If any contract in that initial active processing closure has a contract type BlueId that the processor does not support, the processor MUST return a must-understand capability failure and MUST NOT: - -- mutate the document; -- create markers; -- deliver lifecycle events; -- emit triggered events; -- consume gas. - -If an unsupported contract type is introduced or discovered only after runtime mutation has begun, the processor MUST treat it as a deterministic runtime fatal at the scope where it is discovered. - -### 2.7 Provider requirements (normative) - -A processor MAY use a Blue Language provider to resolve contract types or compute scope Content BlueIds. Provider use MUST follow Blue Language provider verification rules. - -If required provider content is unavailable during processing, the affected scope MUST terminate fatally. If the failure is detected during the initial must-understand capability check, the result is a capability failure instead. - -### 2.8 Existing terminated markers (normative) - -If a scope contains a valid **Processing Terminated Marker** at `contracts/terminated` before `_PROCESS` begins for that scope, the scope is inactive. The processor MUST NOT initialize it, match channels, run handlers, bridge from it, or drain its FIFO during this invocation. - -Entering `_PROCESS` for an existing terminated scope still incurs the scope-entry charge, because the processor has entered and recognized the scope. No initialization, channel matching, lifecycle delivery, bridging, FIFO drain, or checkpoint work occurs for that inactive scope. - -A parent may replace or remove an embedded child root containing a terminated marker, subject to the boundary rules in §4. A parent replacing the child root may thereby install a fresh child scope for a later invocation. - ---- - -## 3. Contracts and Runtime Capabilities - -### 3.1 `contracts` map (normative) - -Every active scope MAY contain a `contracts` object: - -```yaml -contracts: - : -``` - -The map key is the contract's scope-local runtime key. It participates in deterministic ordering and handler binding. - -Contracts are Blue nodes and are identity-bearing content under the Blue Language. Runtime execution does not change that language fact. - -Contracts are ordinary mutable document content except for reserved processor keys. A handler may add, replace, or remove non-reserved contract entries subject to boundary rules, Blue Language validity, and must-understand discovery rules. Such mutations do not execute immediately merely because they were written; they affect only later contract-discovery points defined by this specification. - -### 3.1.1 Contract-map key grammar (normative) - -A contract-map key is the object member name under a scope's `contracts` map. For Blue Contracts 1.0, a contract-map key MUST: - -- be a non-empty Text string; -- be representable as a Blue ordinary child-field key; -- not equal any Blue Language reserved key; -- not equal any Blue Language reserved-invalid key; -- not contain an empty runtime-pointer segment when escaped and used in a runtime pointer; -- be addressable by a Blue Runtime Pointer after RFC 6901 segment escaping. - -Keys may contain `/` or `~`; those characters are escaped only when constructing runtime pointers. The stored object key remains the raw key string. - -Invalid contract-map keys are deterministic runtime fatals when discovered in an active scope, or capability failures when detected during the initial must-understand check. - -### 3.2 Contract roles (normative) - -A contract entry MUST have one of these runtime roles, determined by its effective type: - -| Role | Meaning | -|---|---| -| **Channel** | Event entry point. It decides whether an event is accepted at a scope and may adapt it into a channelized payload. | -| **Handler** | Deterministic logic bound to exactly one channel key in the same scope. | -| **Marker** | Informational state or policy. Markers do not run contract logic, but the processor obeys supported marker semantics. | - -A concrete contract type MAY be external to this specification. If a processor claims to support it, it MUST implement that type's deterministic semantics exactly. - -Blue Contracts 1.0 core recognizes only Channel, Handler, and Marker roles. A contract whose effective type is a subtype of Contract but not a subtype of one of these roles is an extension-role contract. If the processor does not declare support for that exact extension role type BlueId, the contract is unsupported and subject to must-understand/fatal rules. Extension roles MUST NOT be treated as inert merely because they are not Channel, Handler, or Marker. - -### 3.3 Channels (normative) - -A channel evaluates an incoming event in a scope and produces either: - -- no delivery; or -- one channelized delivery payload for handlers bound to that channel. - -A channel MAY: - -- accept or reject events according to its type semantics; -- adapt or reshape an accepted event into a channelized payload; -- read and, where allowed by this specification, cause processor updates to the scope's **Channel Event Checkpoint**; -- call `consumeGas(units: Integer)` through the processor interface; -- invoke `terminate(cause, reason?)`. - -A channel MUST NOT directly mutate the selected document. The only processor state a channel can affect is through permitted processor operations specified here. - -Processor-managed channels are fed only by the processor. External events MUST NOT directly enter **Document Update**, **Triggered Event**, **Lifecycle Event**, or **Embedded Node** channels. - -### 3.4 Handlers (normative) - -A handler is bound to exactly one channel in the same scope by its `channel` field, whose value is the channel's contract-map key. - -A handler MAY: - -- request document changes by returning a list of **Json Patch Entry** objects; -- emit Blue event nodes; -- call `consumeGas(units: Integer)`; -- invoke `terminate(cause, reason?)`. - -No other side effects are permitted. - -A handler MUST be deterministic. Given the same document snapshot, channelized payload, contract content, and allowed context, it MUST return the same result. - -### 3.4.1 Contract execution context (normative) - -A handler/channel execution context exposes at most: - -- executing scope pointer; -- current selected document view, read-only; -- channelized payload, read-only; -- original `PROCESS` event, read-only; -- current contract entry resolved content, read-only; -- current channel entry resolved content, read-only when applicable; -- processor version; -- supported external contract type IDs; -- deterministic gas interface; -- effect-buffering methods for allowed result effects. - -It MUST NOT expose wall-clock time, randomness, network access, hidden mutable state, object identity, or host process state unless a supported extension explicitly defines deterministic semantics. - -### 3.5 Markers (normative) - -Markers carry runtime state or policy. They do not run logic. - -Processor-managed marker slots are: - -- **Process Embedded** at `contracts/embedded`; -- **Type Generalization Policy** at `contracts/generalization`, when present; -- **Processing Initialized Marker** at `contracts/initialized`; -- **Processing Terminated Marker** at `contracts/terminated`; -- **Channel Event Checkpoint** at `contracts/checkpoint`. - -A processor MAY support additional marker types. Unsupported marker types in an active scope are subject to must-understand rules because markers are contract types. - -### 3.6 Reserved processor keys (normative) - -The following keys are reserved under a scope's `contracts` map: - -| Key | Required type | -|---|---| -| `embedded` | Process Embedded | -| `generalization` | Type Generalization Policy | -| `initialized` | Processing Initialized Marker | -| `terminated` | Processing Terminated Marker | -| `checkpoint` | Channel Event Checkpoint | - -If any reserved key exists with an incompatible type or invalid shape, the scope MUST terminate fatally, except when detected during the initial must-understand check, in which case the processor returns capability failure with no mutation. - -Each processor-managed marker type listed above MUST appear at most once per scope and only at its reserved key. A marker of one of these types under any key other than its reserved key is a deterministic runtime fatal. - -### 3.7 Reserved-key write protection (normative) - -Handlers and channels MUST NOT patch any reserved key path or its descendants: - -```text -/.../contracts/embedded -/.../contracts/generalization -/.../contracts/initialized -/.../contracts/terminated -/.../contracts/checkpoint -``` - -Attempting to `add`, `replace`, or `remove` such a path is a deterministic runtime fatal at the executing scope. - -Exception: a handler or channel executing in scope `S` MAY patch `JOIN_SCOPE_PATH(S, "/contracts/embedded/paths")` and its list elements, provided the resulting `contracts/embedded` marker remains a valid Process Embedded marker. The patch MUST NOT replace or remove `contracts/embedded` as a whole, MUST NOT change `contracts/embedded/type`, and MUST NOT write any other field under `contracts/embedded` unless this specification explicitly defines it. - -This exception exists because Process Embedded `paths` is a scope-local processing policy, not a processor-generated lifecycle/checkpoint state. It is what makes dynamic embedded traversal and the no-resurrection rule observable. - -Patches to `contracts/generalization`, `contracts/initialized`, `contracts/terminated`, and `contracts/checkpoint` remain forbidden to handlers and channels. - -Processor writes to reserved keys are permitted only as specified in this document. - -A handler or channel patch MUST NOT target the executing scope's `contracts` map as a whole if the effect would add, replace, remove, or change any reserved processor key or reserved-key descendant in that same scope. In particular, a patch at `JOIN_SCOPE_PATH(scope, "/contracts")` is a deterministic runtime fatal unless every existing reserved processor key and reserved-key descendant in that scope is preserved as the same selected-document Blue node after the Blue Language node normalization required for selected-document insertion and canonical comparison. - -For this rule, equality is semantic Blue-node equality of the selected-document subtree, not source serialization byte equality. Implementations MUST NOT compare YAML or JSON source bytes. - -The ancestor-write exemption applies only when the patch target is a declared embedded child root being replaced or removed as a whole by its parent. In that case, reserved processor keys inside the replaced child subtree are child-scope state and the operation is governed by the embedded boundary rules in §4. - -### 3.8 Read-only inputs (normative) - -Contracts MUST treat delivered event objects, document snapshots, and context objects as read-only. - -All document changes MUST occur only through explicit **Json Patch Entry** operations returned to the processor. - -A processor MAY enforce read-only inputs by cloning, freezing, capability-safe references, or contract sandboxing. Observable behavior MUST be as if contracts cannot mutate delivered payload objects. - -### 3.9 Deterministic ordering (normative) - -Whenever multiple channels or handlers are eligible at a scope, the processor MUST sort them by: - -1. effective `order` value, ascending; missing `order` is `0`; -2. contract-map key, lexicographic by Unicode code point. - -This ordering applies to: - -- external channel matching; -- Document Update channels; -- Triggered Event channel handlers; -- Lifecycle Event channels; -- Embedded Node channels; -- handlers within any channel. - -### 3.9.1 Dispatch snapshots (normative) - -For a single channel delivery, the processor determines the eligible handler list once, immediately before the first handler for that delivery is invoked. The list contains handler keys and resolved handler recognition views in `(order, key)` order. - -The dispatch snapshot includes the resolved executable contract content needed to execute each snapshotted handler or channel under its concrete runtime. If a prior handler mutates, replaces, or removes a later handler's or channel's contract entry during the same delivery or Phase 3 candidate loop, the later snapshotted contract still executes using its snapshotted resolved contract content. The ordinary selected document view supplied as document context remains the current post-mutation selected document at the time of execution. - -A dispatch snapshot freezes what contract is being called; it does not freeze ordinary document state read by that contract unless the concrete contract runtime defines a read snapshot. - -Mutations to `contracts` during that delivery do not add, remove, reorder, or alter handlers already snapshotted for that delivery. Such mutations affect only later contract-discovery points. - -External channel candidates for Phase 3 are snapshotted once at the beginning of Phase 3 for that scope. The snapshot contains candidate channel keys and resolved channel recognition views in `(order, key)` order. Mutations during Phase 3 do not add, remove, reorder, or alter candidates in the current Phase 3 loop, but later phases and later invocations observe the mutated selected document. - -Processor-managed channel discovery for each Document Update, Triggered, Lifecycle, or Embedded Node delivery is performed immediately before that delivery's channel routing begins and is then snapshotted for that delivery. - -For Triggered FIFO processing, processor-managed Triggered Event Channel discovery is performed separately for each dequeued FIFO event, immediately before routing that event. - -For Embedded Node bridging, Embedded Node Channel discovery is performed separately for each recorded child emission, immediately before routing that emission to the parent. - -For Document Update, discovery is performed separately for each Document Update payload created by each successful patch, generated generalization write, or processor-managed patch. - -For Lifecycle, discovery is performed separately for each lifecycle event. - -A scope termination or cut-off still stops remaining work even if the handler or channel was present in a dispatch snapshot. - -### 3.10 Same-scope binding (normative) - -Handlers MUST only bind to channels in the same scope. A handler whose `channel` field names no channel in the same scope is inert unless a profile declares it invalid. A handler MUST NOT bind to a parent, child, embedded, or referenced node's channel. - -A handler is eligible only for channelized deliveries produced by the channel it names. - -### 3.11 Contract result application order (normative) - -Handlers and supported channels may request effects during execution. The processor captures those requests into an effect buffer. The effects do not mutate the selected document, enqueue events, or terminate the scope until the processor applies the normalized result through `APPLY_CONTRACT_RESULT`. - -When a handler returns a result, or when a concrete supported channel type explicitly permits a channel result, the processor applies it in this order: - -1. add explicit gas consumed to `RUN.total_gas`; -2. apply patches in result order, each with immediate cascades and post-patch soundness validation; -3. record and enqueue emitted Triggered events in result order; -4. apply requested termination, if any. - -A host-language API may expose methods such as `emitEvent`, `applyPatch`, or `terminate`, but in Blue Contracts 1.0 core these calls are effect-buffering requests, not immediate side effects. - -External channel evaluation results MUST NOT contain handler-only effects such as document patches or Triggered events unless a concrete supported channel type explicitly extends the channel capability surface. In Blue Contracts 1.0 core, patches and Triggered emissions are handler effects. If a core external channel returns patches or Triggered events, the evaluating scope MUST terminate fatally. - -If a fatal error occurs while applying a result, remaining unapplied effects from that result are discarded after the currently failing operation completes its termination handling. - -### 3.11.1 Contract result normalization (normative) - -Before applying a contract result, the processor normalizes absent optional result fields as follows: - -- absent `gasConsumed` is `0`; -- absent `patches` is `[]`; -- absent `triggeredEvents` is `[]`; -- absent `termination` is `null`. - -If a present result field has an invalid shape, the executing scope MUST terminate fatally before any effects from that result are applied, except that handler/channel overhead already charged remains charged. - -For Blue Contracts 1.0 core external channels, result normalization does not grant handler-only effects. A normalized external-channel result containing non-empty `patches` or `triggeredEvents` remains fatal unless a supported profile explicitly extends channel capabilities. - ---- - -## 4. Active Scopes, Embedded Documents, and Isolation - -### 4.1 Process Embedded marker (normative) - -A **Process Embedded** marker under `contracts/embedded` declares embedded child scopes beneath the current scope: - -```yaml -contracts: - embedded: - type: Process Embedded - paths: - - /payment - - /shipping -``` - -Each path is a scope-relative absolute runtime pointer resolved against the current scope by `ABS(scope, path)` (§6.3). - -The processor reads this list dynamically during Phase 1 of `_PROCESS` (§7.3). - -### 4.2 Dynamic traversal (normative) - -When processing embedded children of a scope, the processor MUST: - -1. read the current effective `paths` list; -2. select the first path in list order that has not already been processed in this parent invocation; -3. process the child if its node exists; -4. mark the path as processed whether or not the node existed; -5. re-read `paths` before choosing the next child. - -Additions, removals, and reorderings of `paths` take effect for the next child selection. - -Once a child path has entered the parent invocation's `processed_paths` set, it MUST NOT be processed again in the same invocation, even if removed and re-added. This is the **no resurrection** rule. - -### 4.3 Embedded path validity (normative) - -A path in **Process Embedded** `paths` MUST: - -- be a valid runtime pointer beginning with `/`; -- not be `/`, because a scope cannot embed itself; -- resolve to an absolute pointer location within the current scope's pointer domain; -- be unique within the list. - -A malformed embedded path is a deterministic runtime fatal at the scope that declares it. - -If a valid embedded path does not exist in the selected document when selected for traversal, it is skipped and marked processed for this invocation. - -If a selected embedded path exists but its root node is not an object, it is not a valid embedded scope and causes deterministic runtime fatal termination at the declaring scope. - -### 4.4 Single selected document view (normative) - -All scopes patch the same selected document view. - -An embedded child patches its subtree in place. Parent and ancestor scopes observe those changes through Document Update cascades and subsequent reads. - -Referenced nodes remain compact unless a Blue Language expansion operation materializes them as part of a view operation. Expansion is not a runtime patch unless performed through an explicit patch. - -### 4.5 Boundary rule (normative) - -Let the executing scope be absolute pointer `S`. Let `E` be the set of embedded child root pointers declared by `S`'s current **Process Embedded** marker, resolved to absolute pointers. - -A patch issued while executing in scope `S` is permitted only if: - -1. `STRICTLY_INSIDE(patch.path, S)`, or, for a parent patch, `patch.path` is equal to a declared embedded child root; -2. `DESCENDANT_OR_EQUAL(patch.path, S)`; and -3. `STRICTLY_INSIDE(patch.path, X)` is false for every embedded child root `X` in `E`. - -Consequences: - -- A parent MAY add, replace, or remove an embedded child root as a whole. -- A parent MUST NOT patch inside an embedded child root. -- A child MAY patch strict descendants inside its own subtree. -- A child MUST NOT add, replace, or remove its own scope root. -- No contract at any scope may patch the document root `/`. - -Violations are deterministic runtime fatals at the executing scope. - -### 4.6 Self-root mutation forbidden (normative) - -While executing in scope `S`, a handler or channel MUST NOT target exactly `S` with `add`, `replace`, or `remove`. - -Only an ancestor may add, replace, or remove a child root. This prevents a scope from cutting or replacing the balloon that contains its own execution context. - -### 4.7 Root target forbidden (normative) - -No handler or channel may target the document root `/` with any patch operation. Replacing or removing the entire document is forbidden. - -A higher-level API MAY replace the entire document between invocations, but that is outside `PROCESS`. - -### 4.8 Balloon cut-off (normative) - -If an ancestor removes or replaces an active child scope root while that child is being processed, the child scope is cut off for the remainder of the current invocation. - -The currently executing channel or handler call is allowed to return. The processor completes the effect currently being applied, records any emissions already produced, and then performs no further work for that cut-off scope: - -- no additional handlers; -- no local FIFO drain; -- no further patches from that scope; -- no further emissions from that scope. - -Already recorded emissions remain in `RUN.emitted_by_scope[child]` and may be bridged to the parent if the parent has a matching **Embedded Node Channel**. - -Re-adding the same path later in the same parent invocation does not schedule it again because of the no-resurrection rule. - ---- - -## 5. Events and Processor-Managed Channels - -### 5.1 Event model (normative) - -Events are Blue nodes. They may be scalar, list, object, or pure reference nodes, subject to Blue Language validity. - -An event has no processor envelope unless a concrete channel type defines one as its event payload. - -Events delivered to contracts are read-only. - -A node passed to `emitEvent` MUST normalize successfully under `NORMALIZE_RUNTIME_NODE_FOR_INSERTION(node, event)` and be a valid Blue node for event delivery. If an emitted node is invalid under the Blue Language data model, the emitting scope MUST terminate fatally before the event is recorded, enqueued, bridged, or charged as a successful emission. - -Processor-emitted event instances MUST include a `type` field whose value is a pure reference to the canonical runtime event type BlueId. - -For example, a Document Update event instance has: - -```yaml -type: - blueId: -op: replace -path: /... -before: ... -after: ... -``` - -The same requirement applies to Document Processing Initiated, Document Processing Terminated, and Document Processing Fatal Error. - -### 5.2 Channelized payloads (normative) - -A **channelized payload** is the event object delivered by a channel to its handlers. - -For processor-managed channels, this specification defines the payload. For external channels, the channel type defines whether the payload is the original event, a projection of it, or a channel-specific wrapper. - -Handler event matching operates on the channelized payload, not on hidden processor state. - -Channelized payloads have the same immutability guarantees as input events, snapshots, and context objects. - -An external channel may return the original event, a newly constructed Blue node, a deterministic projection, or a wrapper, but any structure sharing MUST be unobservable to contracts. - -Portable external channel types SHOULD declare a payload type or payload schema BlueId. If omitted, payload shape is part of the concrete channel type's prose semantics and is not independently portable. - -If an accepted external channel delivery declares an effective `payloadType` or payload schema BlueId, the produced channelized payload MUST conform to that type or schema under Blue Language resolution rules. If the channel accepts but produces a non-conforming payload, the evaluating scope MUST terminate fatally. A channel MAY reject the event before producing a payload. - -### 5.3 Document Update Channel (normative) - -The processor MUST support **Document Update Channel**. - -A Document Update Channel is fed only by the processor after a successful patch. - -For each patch, the processor delivers one **Document Update** event per participating scope in the cascade, from origin scope to ancestors up to root. - -A Document Update Channel declares a scope-relative `path`. It matches when `DESCENDANT_OR_EQUAL(patch.path, ABS(scope, path))` is true. - -Payload fields: - -- `op`: `add`, `replace`, or `remove`; -- `path`: changed path relative to the receiving scope; -- `before`: snapshot at the changed path before the patch, or null if absent; -- `after`: snapshot at the changed path after the patch, or null for remove. - -All handlers at the same receiving scope for the same patch MUST see the same immutable payload object, except that handler-local context may differ. - -`before: null` and `after: null` in Document Update payloads are processor runtime absence sentinels. They are part of the delivered runtime payload. They indicate that the target did not exist before the patch or does not exist after a remove. - -Because Blue Language identity cleaning removes null object fields, processors MUST NOT rely on the BlueId of a Document Update event to preserve absence sentinels unless a concrete event type defines an identity-preserving wrapper. Handlers read these sentinels from the delivered payload before any BlueId cleaning step. - -A future version may replace these sentinels with explicit `beforePresent` and `afterPresent` booleans. Blue Contracts 1.0 uses null sentinels for delivery compatibility. - -### 5.4 Triggered Event Channel (normative) - -The processor MUST support **Triggered Event Channel**. - -Handlers emit Triggered events through `emitEvent(node)`. The processor records each emitted node under the emitting scope and enqueues it into that scope's persistent FIFO. - -A scope's Triggered FIFO is drained at most once per `_PROCESS` invocation for that scope, during Phase 5. It MUST NOT drain during Document Update cascades. - -If a scope has no Triggered Event Channel, emitted events are still recorded under that scope and may be bridged upward, but they are not locally delivered. - -### 5.5 Lifecycle Event Channel (normative) - -The processor MUST support **Lifecycle Event Channel**. - -Lifecycle events are processor-emitted nodes such as: - -- **Document Processing Initiated**; -- **Document Processing Terminated**. - -Lifecycle events are delivered at a scope through Lifecycle Event Channels in that scope. They are also recorded as bridgeable emissions for parent **Embedded Node Channel** handling. - -Lifecycle events themselves are not enqueued into the scope's Triggered FIFO. Lifecycle handlers may emit Triggered events, and those emitted events are enqueued normally. - -At root, lifecycle events recorded through `RECORD_BRIDGEABLE` are appended to the run's `triggered_events` outbox. - -### 5.6 Embedded Node Channel (normative) - -The processor MUST support **Embedded Node Channel**. - -An Embedded Node Channel in a parent scope bridges emissions from a processed child scope after the child finishes and after the parent handles the external event, but before the parent drains its Triggered FIFO. - -A channel declares `childPath`. It matches child emissions from the processed child whose path equals `ABS(parentScope, childPath)`. - -Bridgeable child emissions include: - -- Triggered events emitted by the child; -- lifecycle events recorded by the child. - -The child emissions are delivered to the parent's Embedded Node Channel handlers in the order they were recorded by the child. They are not automatically enqueued into the parent's Triggered FIFO; parent handlers may emit events if forwarding is desired. - -### 5.7 Processor-managed channels are not checkpoint-gated (normative) - -Document Update, Triggered Event, Lifecycle Event, and Embedded Node channels are never subject to Channel Event Checkpoint gating. - -Only external channels are checkpoint-gated (§10). - ---- - -## 6. Runtime Pointers and JSON Patch Semantics - -### 6.1 Blue Runtime Pointer (normative) - -This specification uses **Blue Runtime Pointer** strings for patch paths, channel paths, and scope paths. - -A Blue Runtime Pointer is a deterministic JSON-pointer-compatible path with these conventions: - -- `/` denotes the root of the current pointer domain; -- child pointers begin with `/` followed by one or more escaped path segments; -- the empty string is not a valid runtime pointer; -- segment escaping follows RFC 6901: `~0` represents `~`, and `~1` represents `/`; -- unescaped `/` separates path segments; -- the array append token `-` is valid only as a patch target segment where this specification permits it. - -Because `/` is the root pointer in this specification, a direct object key equal to the empty string is not addressable by Blue Runtime Pointer. Applications needing such keys must use an application-level escaped representation. - -Blue Runtime Pointers are not identical to Blue Language view paths. In Blue Contracts 1.0, `/` denotes the runtime document root and is not a patch target. In Blue Language view paths, the empty string `""` denotes the root under RFC 6901 semantics. Implementers MUST NOT reuse one parser for the other without an explicit mode. - -### 6.2 Pointer normalization (normative) - -Processors MUST normalize pointers before comparison: - -- no trailing slash except `/` itself; -- valid escape sequences only; -- no empty segments; -- no `.` or `..` path semantics; -- no percent-encoding or URI-fragment decoding unless performed by an external envelope before runtime. - -Malformed pointers are deterministic runtime fatals when used by a contract or marker. - -### 6.3 Helper functions (normative) - -`ABS(S, P)` is the absolute document pointer for a scope-relative pointer `P` declared at scope `S`. - -Examples: - -```text -ABS("/", "/a") = "/a" -ABS("/order", "/id") = "/order/id" -ABS("/order", "/") = "/order" -``` - -`JOIN_SCOPE_PATH(S, P)` is equivalent to `ABS(S, P)`, where `P` is a scope-relative runtime pointer beginning with `/`. Implementations MUST NOT construct runtime pointers by raw string concatenation, because root scope `/` would otherwise produce double slashes. - -`DESCENDANT_OR_EQUAL(A, B)` is true when normalized pointer `A` equals normalized pointer `B`, or when `B` is an ancestor of `A` by complete path segments. Implementations MUST NOT use raw string prefix tests; for example `/ab` is not inside `/a`. - -`STRICTLY_INSIDE(A, B)` is true when `DESCENDANT_OR_EQUAL(A, B)` and `A != B`. - -`escape_pointer_segment(text)` returns one RFC 6901-escaped runtime pointer segment. - -`relativize_pointer(S, A)` returns a pointer relative to scope `S` for an absolute pointer `A`. It returns `/` when `A == S`. - -Examples: - -```text -relativize_pointer("/", "/a/b") = "/a/b" -relativize_pointer("/a", "/a/b") = "/b" -relativize_pointer("/a/b", "/a/b") = "/" -``` - -`relativize_snapshot(S, node)` returns an immutable subtree snapshot as observed at scope `S`. - -### 6.4 Json Patch Entry validation (normative) - -Handlers return **Json Patch Entry** objects. A runtime patch entry MUST have this effective shape: - -```yaml -op: add | replace | remove -path: -val: # required for add/replace; absent for remove -``` - -Rules: - -- `op` and `path` are required. -- `op` MUST be one of `add`, `replace`, or `remove`. -- `path` MUST be an absolute Blue Runtime Pointer. -- `path` MUST NOT be `/`. -- `val` is required for `add` and `replace`. -- `val` MUST be absent for `remove`. -- Other RFC 6902 operations such as `move`, `copy`, and `test` are unsupported and cause deterministic runtime fatal termination. - -A malformed patch entry is a deterministic runtime fatal at the executing scope. - -Despite the historical name **Json Patch Entry**, this is not full RFC 6902. It uses RFC 6901-compatible runtime pointers but supports only `add`, `replace`, and `remove`, with Blue-specific upsert and auto-materialization rules. The canonical runtime type name remains `Json Patch Entry` for Blue Contracts 1.0 registry stability. - -### 6.4.1 Runtime node insertion normalization (normative) - -`NORMALIZE_RUNTIME_NODE_FOR_INSERTION(node, context)` converts a patch `val`, emitted event, checkpoint subject, or processor-created runtime node into the selected-document form used by `PROCESS`. - -The algorithm: - -1. rejects a root `blue` directive; -2. rejects unresolved authoring aliases unless a higher-level API has already preprocessed them outside runtime; -3. applies Blue Language wrapper normalization; -4. applies primitive scalar inference for bare scalars; -5. applies Source-list placeholder normalization for list elements, including recursive empty-object normalization; -6. validates reserved field shapes and payload-kind exclusivity; -7. rejects invalid Blue Language nodes. - -This algorithm does not perform full Blue Language resolution unless resolution is required for subsequent contract discovery, type soundness validation, event identity, checkpoint-subject identity, or Content BlueId calculation. - -### 6.5 Patch application order (normative) - -Patches returned by one handler are applied immediately in list order. Each successful patch triggers its full Document Update cascade before the next patch is applied. - -Patches resolve against the current selected document state after all prior patches, cascades, and Direct Writes in the same run. - -### 6.6 Object targets (normative) - -For object containers: - -- `add` inserts a new member or replaces an existing member; -- `replace` behaves as upsert; -- `remove` deletes an existing member; -- removing a non-existent member is a deterministic runtime fatal. - -Missing intermediate object containers are auto-materialized as empty objects when applying `add` or `replace`. Auto-created containers are part of the same patch operation; the Document Update event describes the final requested path, not each intermediate container. - -If an existing intermediate value is not an object when an object container is required, the patch is a deterministic runtime fatal. - -### 6.7 Array targets (normative) - -For array containers: - -- path segments used against arrays MUST be canonical non-negative decimal indices with no leading zeros, except the single digit `0`, or `-`; -- `add /items/- val` appends; -- `add /items/i val` inserts at index `i`, where `0 <= i <= length`; -- `replace /items/i val` overwrites an existing element, where `0 <= i < length`; -- `remove /items/i` deletes an existing element and shifts later elements left; -- `-` is invalid for `replace` and `remove`; -- `/items/01` is malformed for array addressing; -- out-of-range array indices are deterministic runtime fatals. - -The processor MUST NOT auto-materialize arrays. If an intermediate array is missing, a patch may create an object member containing an array as its `val`, but it cannot infer an array solely from a numeric path segment. - -### 6.8 Snapshots (normative) - -For every successful patch, the processor captures: - -- `before`: the snapshot at `patch.path` before mutation, or null if the target did not exist; -- `after`: the snapshot at `patch.path` after mutation, or null for `remove`. - -Snapshots delivered to handlers are immutable. A processor MAY clone, freeze, or use immutable persistent data structures. - -### 6.9 Patch validity and Blue Language validity (normative) - -A patch `val` MUST normalize successfully under `NORMALIZE_RUNTIME_NODE_FOR_INSERTION(val, patchValue)` before insertion into the selected document. If applying a patch would make the selected document invalid under the Blue Language data model, the patch is a deterministic runtime fatal. - -This specification does not require the processor to re-resolve the entire Blue Language document after every patch unless resolution is needed for post-patch type soundness validation, subsequent contract discovery, contract execution, event identity, checkpoint-subject identity, or Content BlueId calculation. - -### 6.10 Post-patch type soundness and dynamic generalization (normative) - -Every successful handler/channel patch and every processor-managed patch MUST leave the selected document as a valid, type-sound Blue document before any Document Update cascade for that patch is delivered. - -A processor MUST NOT expose a transient state that violates the effective type or schema constraints of the selected document. - -After applying a patch to a tentative copy of the selected document, the processor MUST run `RESTORE_TYPE_SOUNDNESS` for the affected path. The processor MAY implement this incrementally, but the observable result MUST be as if the affected subtree and all relevant ancestors were rechecked under Blue Language resolution and subtype rules. - -If type soundness can be restored by deterministic dynamic type generalization allowed by the effective generalization policy, the processor commits the patch and generated generalization writes atomically. If type soundness cannot be restored, the patch is a deterministic runtime fatal and the tentative patch is not committed. - -### 6.10.1 Dynamic type generalization (normative) - -Dynamic type generalization is the processor's deterministic repair mechanism for a patch that makes a node no longer conform to its current declared type but still conform to an ancestor type in that type's chain. - -Given a node `N` with current effective type `T`, the processor may generalize `N` by replacing its selected-document `type` with the nearest ancestor type `A` of `T` such that: - -1. `N` conforms to `A` under Blue Language resolution and schema rules; -2. `A` is permitted by the effective Type Generalization Policy; -3. replacing `T` with `A` does not violate an embedded-scope boundary rule; -4. all child and parent constraints remain type-sound after propagation. - -Generalization is unidirectional. A processor MUST NOT specialize a node to a more specific type as a result of a patch unless that specialization was explicitly requested by the patch and validates normally. - -The processor MUST choose the nearest valid permitted ancestor type. If no such ancestor exists, the patch fails with `GeneralizationNoValidType` or `GeneralizationRejected`. - -### 6.10.2 `RESTORE_TYPE_SOUNDNESS` algorithm (normative) - -For a patch whose requested path is `P`, the affected closure is: - -1. the node directly changed by the patch; -2. each ancestor node up to the executing scope root; -3. if the executing scope is the document root, ancestors continue to the document root, which is the same node; -4. if the patch was issued by an ancestor against a declared embedded child root as a whole, the affected closure includes that child root and the executing ancestor path as allowed by §4.5. - -A patch executing inside an embedded child scope MUST NOT generalize ancestor scopes outside that embedded scope. If the child change would require ancestor-scope generalization to restore global type soundness, the patch is a runtime fatal unless the ancestor itself issued the patch or a future profile explicitly permits cross-scope generalization. - -Algorithm: - -```text -function RESTORE_TYPE_SOUNDNESS(document, executingScope, changedPath): - candidate = tentative patched document - writes = [] - - for nodePath from deepest affected node upward to executingScope: - result = CHECK_NODE_CONFORMS(candidate, nodePath, currentType(nodePath)) - CHARGE_TYPE_SOUNDNESS_CHECK(nodePath) - if result conforms: - continue - - gen = NEAREST_VALID_GENERALIZATION(candidate, nodePath, policy(nodePath)) - if gen none: - fail - - replace nodePath/type with canonical reference to gen.type - append generated write nodePath/type to writes - - repeat upward validation until no new generalization writes are required - return candidate, writes -``` - -A processor MAY optimize this algorithm, but must produce the same selected document, generated writes, Document Update ordering, gas, and fatal behavior. - -### 6.10.3 Type Generalization Policy marker (normative) - -A scope MAY contain a Type Generalization Policy marker at `contracts/generalization`. If absent, the effective default is: - -```yaml -defaultMode: nearest-valid -rules: [] -``` - -The policy controls processor-generated type generalization in that scope. - -Fields: - -- `defaultMode`: `nearest-valid` or `reject`. Missing means `nearest-valid`. -- `rules`: optional List of rules. - -Each rule has: - -- `path`: scope-relative runtime pointer identifying the subtree governed by the rule; -- `mode`: `nearest-valid` or `reject`; -- `mustRemainSubtypeOf`: optional type reference. If present, any generalized type at that path MUST be equal to or a subtype of this type. - -Rule selection: - -- Normalize each rule path with `ABS(scope, rule.path)`. -- The most specific matching rule applies, where specificity is longest normalized path by complete segments. -- If two rules have the same normalized path, the later rule in list order wins. - -`mode: reject` means a patch that would require generalization at the governed path fails instead of generalizing. - -`contracts/generalization` is processor-managed. Handlers and channels MUST NOT patch it or its descendants unless a future profile explicitly allows policy mutation. It is read during post-patch soundness validation. - -### 6.10.4 Generalization writes, cascades, and gas (normative) - -A generated type generalization write is a processor-managed companion write to `/type`. It is not a handler/channel patch and does not pay boundary check gas. It is still an observable selected-document mutation. - -A patch and its generated generalization writes are committed atomically. If any required generalization fails, neither the requested patch nor any generated write is committed. - -After a successful commit, Document Update cascades are delivered in this order: - -1. the original requested patch path; -2. generated generalization writes in deepest-to-root order. - -Each generated type write produces its own Document Update cascade. Triggered FIFO is not drained until all cascades for the original patch and all generated generalization writes have completed. - -For gas: - -- post-patch type-soundness validation costs `5` gas per checked node; -- each generated generalization write costs the same as a processor-managed `replace` patch for the new `type` value, without handler/channel boundary check gas; -- each generated write's Document Update cascade charges cascade gas normally for participating scopes. - -### 6.10.5 Generalization examples (informative) - -Price example: - -```yaml -# Before -price: - type: { blueId: } - amount: 150 - currency: EUR - -# Patch -- op: replace - path: /price/currency - val: USD - -# After generalization -price: - type: { blueId: } - amount: 150 - currency: USD -``` - -Parent propagation: - -```text -If the root type European Product requires price: Price in EUR, and /price -generalizes to Price, the root must generalize to the nearest valid parent -type, such as Global Product, when policy permits it. -``` - -Policy floor: - -```yaml -contracts: - generalization: - type: Type Generalization Policy - rules: - - path: / - mode: nearest-valid - mustRemainSubtypeOf: { blueId: } -``` - -This allows generalization from `EU Bank Transfer PayNote` to `Bank Transfer PayNote`, but forbids generalization to plain `PayNote`. - ---- - -## 7.

They are visible to subsequent logic in the same run and persist in `new_doc`. - -A Direct Write to a processor-managed reserved path MUST create any missing object containers required for that reserved path, such as `contracts`, `checkpoint`, and `lastEvents`, when those containers are needed to perform a processor-required Direct Write. Such container creation is part of the Direct Write, produces no Document Update cascade, and has only the Direct Write gas specified in §12. If an intermediate path exists but is not an object where an object container is required, the Direct Write is a deterministic runtime fatal at the scope performing the processor operation. - -Handlers and channels cannot perform Direct Writes. - ---- - -## 8. Initialization and Lifecycle - -### 8.1 First-run initialization (normative) - -If a scope does not have `contracts/initialized` when Phase 2 begins, the processor initializes the scope. - -Initialization performs, in order: - -1. compute the scope Content BlueId before initialization; -2. publish **Document Processing Initiated** through Lifecycle Event Channels at the scope; -3. add **Processing Initialized Marker** under `contracts/initialized` using a processor-managed patch, which MUST trigger a Document Update cascade. - -The marker stores the pre-init scope Content BlueId in `documentId`. - -If the processor cannot compute the scope Content BlueId because required provider content is unavailable or invalid, the scope MUST terminate fatally. - -The pre-initialization scope Content BlueId is calculated from the selected scope subtree immediately after Phase 1 embedded processing for that scope and before the Processing Initialized Marker is written. - -The input to Content BlueId calculation is the scope subtree as a Blue Language Source-equivalent document after runtime selected-document normalization. It includes materialized non-runtime content and materialized contract content that exists at that scope at that moment. It excludes no fields merely because they are runtime fields, except that the not-yet-written initialized marker is absent. - -If a scope already has a valid terminated marker, initialization does not run. If Content BlueId cannot be computed deterministically because required provider content is unavailable, the scope terminates fatally. - -### 8.2 Initialization pseudocode (normative) - -```text -function INITIALIZE_SCOPE(document, scope): - CHARGE_INITIALIZATION(scope) - pre_init_id = compute_scope_content_blue_id(document, scope) - - initiated = make_document_processing_initiated(documentId=pre_init_id) - document = DELIVER_LIFECYCLE(document, scope, initiated) - - if INACTIVE(scope): - return document - - marker = make_processing_initialized_marker(documentId=pre_init_id) - patch = { op: "add", path: JOIN_SCOPE_PATH(scope, "/contracts/initialized"), val: marker } - document = APPLY_PROCESSOR_PATCH_WITH_CASCADE(document, origin_scope=scope, patch=patch) - - return document -``` - -Processor-managed initialization marker patches are not handler/channel patches and may target the reserved `initialized` key. They still produce Document Update cascades. - -### 8.3 No eager checkpoint creation (normative) - -Initialization MUST NOT create `contracts/checkpoint` merely because a scope is initialized. Checkpoints are created lazily only when an external channel candidate accepts at that scope and requires newness evaluation (§10). - -### 8.4 Lifecycle events and root outbox (normative) - -A lifecycle event recorded at root MUST be appended to the run's `triggered_events` outbox. - -Lifecycle events recorded at non-root scopes are not returned directly unless they are bridged by an ancestor and re-emitted at root by handlers. - -### 8.5 Persistent initialization (normative) - -Once a valid **Processing Initialized Marker** exists at a scope, subsequent invocations MUST NOT re-run initialization for that scope unless the marker has been removed by an ancestor replacing or removing the scope root outside the scope's own execution. - -Handlers and channels cannot remove or replace `contracts/initialized` directly because reserved keys are write-protected. - ---- - -## 9. Document Updates, Cascades, FIFOs, and Bridging - -### 9.1 One patch, one cascade (normative) - -Every successful patch causes exactly one Document Update cascade. - -If a patch generates type generalization writes, each generated write also causes exactly one Document Update cascade after the requested patch cascade, in deepest-to-root order. - -The cascade starts at the patch's origin scope and proceeds to each ancestor up to root, in order. - -For an origin scope `/a/b`, cascade scope order is: - -```text -/a/b -> /a -> / -``` - -Scopes that no longer exist are marked cut off and do not receive further work. - -### 9.2 Cascade matching (normative) - -At each receiving scope `S`, a Document Update Channel with path `P` matches iff `DESCENDANT_OR_EQUAL(patch.path, ABS(S, P))` is true. - -Matching uses absolute paths. Payload paths are scope-relative. - -Document Update channel discovery for a patch uses the post-patch Selected Document View. A Document Update Channel removed by the patch does not receive that patch's Document Update. A Document Update Channel added by the patch may receive that same patch's Document Update if it exists in a participating scope and matches the changed path in the post-patch view. - -If post-patch Document Update discovery encounters a materialized contract entry whose type is unsupported, malformed, or invalid under Contract Recognition Resolution, the receiving scope where discovery occurs MUST terminate fatally under the normal runtime-discovery rules. The original patch remains applied unless the failing scope is otherwise rolled back by a supported profile; Blue Contracts 1.0 core has no rollback. - -Example: - -```text -Patch path: /a/z/k -At scope /a, payload path: /z/k -At root /, payload path: /a/z/k -``` - -### 9.3 Uniform payload per scope (normative) - -For a given patch and receiving scope, the processor creates one immutable Document Update payload. All matching channels and handlers at that scope receive that same payload object. - -The payload object MUST NOT be mutated by handlers. - -### 9.4 No drain during cascades (normative) - -Triggered events emitted by handlers during a Document Update cascade are: - -- recorded under the emitting scope; -- enqueued into that scope's Triggered FIFO; -- not delivered through the Triggered Event Channel during the cascade. - -They may be delivered only during that scope's Phase 5 drain. - -### 9.5 FIFO persistence within a run (normative) - -Each scope has one FIFO for the entire processor invocation. - -Events are enqueued in emission order. Events emitted during FIFO drain append to the tail and are processed during the same drain if the scope remains active. - -If a scope terminates or is cut off, its FIFO is dropped. - -### 9.6 Bridge timing (normative) - -A parent bridges child emissions in Phase 4: - -- after embedded children have been processed; -- after the parent handles the incoming external event; -- before the parent drains its own Triggered FIFO. - -This ordering is normative. - -Informative rationale: bridge-before-drain lets parent Embedded Node Channel handlers react to child emissions and enqueue parent-scope Triggered events that can still be drained in the same parent invocation; reversing the order would defer those reactions to a later invocation. - -### 9.7 Bridge ordering (normative) - -Bridge processing order is: - -1. child scopes in the parent invocation's `processed_paths` insertion order; -2. child emissions in the order recorded under that child; -3. matching Embedded Node Channels sorted by `(order, key)`; -4. handlers within each Embedded Node Channel sorted by `(order, key)`. - -### 9.8 Bridge scope (normative) - -Embedded Node Channel handlers execute in the parent scope, not in the child scope. Patches they produce are parent-scope patches and are subject to the parent's boundary rules. - -Informative cascade/bridge diagram: - -```text -child patch - -> child Document Update cascade upward - -> child emissions recorded - -parent Phase 4 bridge - -> parent Embedded Node Channel delivery - -> parent FIFO enqueue by parent handlers - -> parent Phase 5 drain -``` - ---- - -## 10. External Channels and Channel Event Checkpoints - -### 10.1 External channels (normative) - -An **external channel** is any supported Channel type other than the processor-managed channel families defined in §5. - -External channels match the input `event` delivered to `PROCESS`. Concrete external channel types define their acceptance and channelization semantics. - -### 10.2 Checkpoint marker (normative) - -A **Channel Event Checkpoint** records the last processed checkpoint subject per external channel key: - -```yaml -contracts: - checkpoint: - type: Channel Event Checkpoint - lastEvents: - channelKey: -``` - -There MUST be at most one checkpoint per scope, and it MUST be under the reserved key `checkpoint`. - -`lastEvents` is keyed by the raw contract-map key of the external channel. The key is escaped only when constructing a runtime pointer used for Direct Write. The selected document stores the raw object key. - -### 10.3 Lazy creation (normative) - -A scope may lack `contracts/checkpoint` until an accepted external channel delivery first requires newness evaluation at that scope. - -Rejected external channel candidates do not create checkpoints. Lazy checkpoint creation occurs after an external channel candidate accepts the input event and before that accepted delivery's newness policy is evaluated. - -When an accepted external channel delivery at scope `S` requires newness evaluation and `contracts/checkpoint` is absent, the processor MUST Direct Write an empty checkpoint before newness evaluation: - -```yaml -lastEvents: {} -``` - -This Direct Write does not emit Document Update and does not consume checkpoint-update gas unless a gas profile explicitly says otherwise. Under §12, lazy creation itself costs zero gas. - -### 10.4 Newness policy (normative) - -For each external channel key, the processor uses a deterministic **newness policy** to decide whether the incoming event should be processed. - -Each external channel has an effective `checkpointIdentityMode`: - -- `contentBlueId` (default): compare Content BlueIds of checkpoint subjects; -- `nodeBlueId`: compare direct Node BlueIds of checkpoint subjects, requiring valid BlueId Input; -- `channelDefined`: the concrete channel type defines deterministic identity. - -The default for Blue Contracts 1.0 external channels is `contentBlueId`. - -A concrete external channel type MAY define its own newness policy. That policy MUST be deterministic and MUST depend only on: - -- the previous checkpoint subject stored in `lastEvents[channelKey]`, if any; -- the incoming event node; -- the accepted channelized payload, if the channel type declares that payload as part of its newness policy; -- the channel contract content; -- deterministic Blue Language identity operations. - -If a concrete channel type does not define a more specific policy, the default policy is **content-idempotent**: - -- if no previous incoming event is stored for the channel key, the event is new; -- otherwise, the event is new iff the incoming event's Content BlueId differs from the previous incoming event's Content BlueId. - -The default content-idempotent policy computes the incoming and stored event identities using the effective `checkpointIdentityMode`. Under the default `contentBlueId` mode, the processor uses the Blue Language Content BlueId pipeline over the normalized checkpoint subjects. Under `nodeBlueId`, the subject MUST already be valid BlueId Input after runtime insertion normalization. - -Provider failure required for this identity calculation is a runtime fatal at the evaluating scope, unless discovered during the initial capability check. - -The stored checkpoint subject remains the incoming event node by default, not the channelized payload. A concrete channel type that declares a non-default `checkpointSubject` MUST define how its newness policy uses that subject. - -The processor stores the checkpoint subject after event preprocessing and runtime checkpoint-subject normalization. It does not store an ambiguous source form unless the concrete channel type explicitly defines that behavior. - -The default policy detects duplicates but does not impose temporal ordering. Channels that require sequence numbers, ledgers, vector clocks, or monotonic timestamps MUST define those rules in their concrete channel type. - -### 10.5 Gating rule (normative) - -For each accepted external channel delivery: - -1. ensure the checkpoint exists, lazily creating it if needed; -2. read `lastEvents[channelKey]`; -3. evaluate the channel's newness policy; -4. if not new, skip handlers and leave the checkpoint unchanged; -5. if new, run handlers; -6. if channel handling completes without scope termination or fatal error, Direct Write `lastEvents[channelKey] = checkpoint_subject(channel, incomingEvent, delivery)`. - -The checkpoint stores the incoming event node, not the channelized payload, unless the concrete external channel type explicitly defines a different checkpoint subject. - -```text -function ENSURE_CHECKPOINT_FOR_ACCEPTED_DELIVERY(document, scope): - checkpoint_path = JOIN_SCOPE_PATH(scope, "/contracts/checkpoint") - if checkpoint absent at checkpoint_path: - emptyCheckpoint = ChannelEventCheckpoint(lastEvents={}) - document = DIRECT_WRITE(document, checkpoint_path, emptyCheckpoint) - return document - -function CHECKPOINT_ALLOWS(document, scope, channelKey, incomingEvent, delivery): - # Pure decision after lazy checkpoint existence has been ensured. - return evaluate_newness_policy(document, scope, channelKey, incomingEvent, delivery) - -function DIRECT_WRITE_CHECKPOINT_UPDATE(document, scope, channel, incomingEvent, delivery): - channelKey = channel.key - subject = NORMALIZE_RUNTIME_NODE_FOR_INSERTION(checkpoint_subject(channel, incomingEvent, delivery), checkpointSubject) - CHARGE_CHECKPOINT_UPDATE() - path = JOIN_SCOPE_PATH(scope, "/contracts/checkpoint/lastEvents/" + escape_pointer_segment(channelKey)) - return DIRECT_WRITE(document, path, subject) - -function checkpoint_subject(ch, incomingEvent, delivery): - if ch.checkpointSubject == "incoming-event": - return incomingEvent - if ch.checkpointSubject == "channelized-payload": - return delivery.payload - if ch.checkpointSubject == "channel-defined": - return deterministic_subject_defined_by_channel_type(ch, incomingEvent, delivery) - return incomingEvent -``` - -The value returned by `checkpoint_subject` MUST be a valid Blue node. If a channel-defined checkpoint subject is invalid or cannot be computed deterministically, the evaluating scope MUST terminate fatally and the checkpoint MUST NOT be updated. - -The object member created at the Direct Write path is the raw `channelKey`; pointer escaping is not part of the stored key. - -### 10.6 Successful channel processing (normative) - -An external channel is considered successfully processed when: - -- its accepted handlers have all run in deterministic order; -- all their patches, emissions, and termination requests have been applied; and -- the scope has not terminated fatally or gracefully during that channel. - -If the scope terminates during the channel, the checkpoint MUST NOT be updated for that channel unless the concrete termination policy explicitly says otherwise. Blue Contracts 1.0 default is no checkpoint update on termination. - -### 10.7 Multiple external channels (normative) - -External channel candidates at a scope are considered in `(order, key)` order. Candidates that accept the same input event each use their own checkpoint entry keyed by their contract-map key. - -One channel being stale does not prevent another channel from running. - -If an earlier channel's handlers patch ordinary document state, later Phase 3 candidate channel executions see the updated Selected Document View as context. However, the Phase 3 external candidate set and candidate recognition views are snapshotted at Phase 3 start under §3.9.1. - -### 10.8 Checkpoint tamper resistance (normative) - -Handlers and channels cannot patch `contracts/checkpoint` or its descendants. Attempts are deterministic runtime fatals. - -Only the processor may create or update checkpoints through Direct Write. - ---- - -## 11. Failure and Termination Semantics - -### 11.1 Capability failure (must-understand) (normative) - -If the initial must-understand capability check fails, the processor MUST NOT run. It returns a capability failure with: - -- unchanged document; -- no triggered events; -- total gas `0`; -- no lifecycle events; -- no termination markers. - -Capability failure is not a runtime fatal because runtime never begins. - -### 11.2 Runtime fatal (normative) - -A deterministic runtime error terminates the executing scope fatally. Runtime fatal causes include, but are not limited to: - -- boundary violation; -- root target patch; -- self-root mutation; -- invalid contract-map key discovered in an active scope; -- malformed patch entry; -- unsupported patch operation; -- invalid pointer; -- invalid patch value after runtime insertion normalization; -- array out-of-range; -- removing a non-existent member; -- non-object embedded scope root selected for traversal; -- malformed required marker; -- reserved-key write attempt; -- post-patch type soundness violation; -- generalization rejected by Type Generalization Policy; -- no valid permitted generalization target; -- duplicate required marker; -- unsupported contract type discovered after runtime mutation has begun; -- invalid contract result shape; -- handler or channel execution error; -- checkpoint creation or update failure; -- gas accounting failure; -- termination Direct Write failure after fallback; -- provider verification failure required for runtime contract recognition, scope Content BlueId calculation, or event identity calculation. - -### 11.3 Contract-requested termination (normative) - -A channel or handler may request graceful termination by invoking `terminate(cause="graceful", reason?)`. - -Graceful termination ends the scope without treating the run as erroneous. - -Contract-requested termination cause MUST be either `graceful` or `fatal`. A graceful request enters graceful termination. A fatal request enters fatal termination and is treated as a contract-declared fatal condition, not as a processor validation error. Any other cause value is a deterministic runtime fatal at the executing scope. - -Profiles MAY restrict handlers or channels to graceful-only termination, but such restriction is outside the Blue Contracts 1.0 core unless represented by a supported policy. - -### 11.4 Termination effects (normative) - -When a scope begins termination, gracefully or fatally, the processor MUST: - -1. If the scope is already terminating or terminated, apply the reentrancy rule below and return. -2. Mark `RUN.terminating_scopes[scope] = true`. -3. Direct Write `JOIN_SCOPE_PATH(scope, "/contracts/terminated")` with **Processing Terminated Marker**: - - `cause: graceful` or `cause: fatal`; - - optional `reason`. -4. Create the **Document Processing Terminated** lifecycle event. -5. Deliver the lifecycle event using `DELIVER_LIFECYCLE`; `DELIVER_LIFECYCLE` records it as bridgeable before routing it to Lifecycle Event Channels. -6. Mark `RUN.terminated_scopes[scope] = true`. -7. Drop the scope's Triggered FIFO. -8. Treat further patch/emit attempts from that scope as no-ops for the remainder of the run. -9. If the terminated scope is root, apply root graceful/fatal completion rules from §11.6-§11.7. - -The termination marker Direct Write does not emit a Document Update. - -If writing the Processing Terminated Marker by Direct Write fails because a required intermediate container is malformed, the processor MUST make one fallback attempt to replace the executing scope's `contracts` field with an object containing only a valid `terminated` marker and any reserved runtime subtrees that can be preserved without violating Blue Language validity. - -If that fallback also fails, the processor MUST abort the run with `TerminationError`. The returned document is the last valid selected document state before the failed termination write, and root fatal outbox behavior is implementation-exposed through the conformance result envelope rather than by a marker that could not be written. - -A processor MUST NOT loop indefinitely attempting termination writes. - -Termination is single-entry per scope per invocation. Once `ENTER_GRACEFUL_TERMINATION` or `ENTER_FATAL_TERMINATION` begins for a scope, that scope is in terminating state. The termination marker and exactly one **Document Processing Terminated** lifecycle event are produced for the first termination cause. Additional `terminate(...)` requests from handlers invoked during termination lifecycle delivery are ignored after their already-applied prior effects. - -Additional termination requests after `RUN.terminated_scopes[scope] = true` are ignored. - -If a deterministic runtime fatal occurs while a root scope is already terminating, the processor MUST append exactly one root outbox-only **Document Processing Fatal Error** if one has not already been appended. This does not change the already-written **Processing Terminated Marker** or the already-created **Document Processing Terminated** event. For non-root scopes, the fatal is suppressed as an additional termination cause; it MUST NOT write a second marker or emit a second lifecycle event. In all cases, the processor MUST abort remaining effects from the currently failing handler result and stop further lifecycle delivery at that terminating scope. No second termination marker charge, lifecycle delivery charge, or fatal termination overhead is charged for a suppressed additional termination cause. - -Terminating state is a reentrancy guard. It does not by itself make lifecycle handlers inactive before the first termination lifecycle delivery completes. - -### 11.5 Non-root fatal (normative) - -A fatal termination in a non-root scope is scope-terminal only by default. - -The parent continues processing unless it is itself terminated by a handler or by a separate fatal error. The child's already recorded emissions, including the termination lifecycle event, remain bridgeable to the parent. - -### 11.6 Root graceful termination (normative) - -If the root scope terminates gracefully, the processor records **Document Processing Terminated** in the root outbox and ends the run. It returns the current document, root outbox, and total gas. - -If §11.4 appends **Document Processing Fatal Error** because a deterministic runtime fatal occurs during root graceful termination lifecycle delivery, the already-written graceful termination marker and lifecycle event remain unchanged, and the root outbox also contains the fatal error signal. - -When both **Document Processing Terminated** and **Document Processing Fatal Error** appear in the root outbox for the same root termination sequence, **Document Processing Terminated** MUST appear before **Document Processing Fatal Error**. - -### 11.7 Root fatal termination (normative) - -If the root scope terminates fatally, the processor MUST: - -1. record **Document Processing Terminated** at root; -2. append **Document Processing Fatal Error** to the root outbox as an outbox-only event; -3. abort the run; -4. return the current document, root outbox, and total gas. - -**Document Processing Fatal Error** is not delivered to Lifecycle Event Channels and is not bridgeable. It is a root outbox signal only. - -When both **Document Processing Terminated** and **Document Processing Fatal Error** appear in the root outbox for the same root termination sequence, **Document Processing Terminated** MUST appear before **Document Processing Fatal Error**. - -### 11.8 Termination pseudocode (informative) - -```text -function ENTER_GRACEFUL_TERMINATION(document, scope, reason): - if RUN.terminated_scopes[scope]: - return document - if RUN.terminating_scopes[scope]: - return document - RUN.terminating_scopes[scope] = true - CHARGE_TERMINATION_MARKER_WRITE() - document = DIRECT_WRITE(document, - JOIN_SCOPE_PATH(scope, "/contracts/terminated"), - ProcessingTerminatedMarker(cause="graceful", reason=reason)) - event = DocumentProcessingTerminated(cause="graceful", reason=reason) - document = DELIVER_LIFECYCLE(document, scope, event) - RUN.terminated_scopes[scope] = true - clear_fifo(scope) - if scope == "/": - if RUN.root_fatal_error_appended: - raise ROOT_FATAL_TERMINATION - raise ROOT_GRACEFUL_TERMINATION - return document - -function ENTER_FATAL_TERMINATION(document, scope, reason): - if RUN.terminated_scopes[scope]: - return document - if RUN.terminating_scopes[scope]: - if scope == "/" and not RUN.root_fatal_error_appended: - RUN.root_events.append(DocumentProcessingFatalError(reason=reason)) - RUN.root_fatal_error_appended = true - RUN.stop_lifecycle_delivery[scope] = true - abort_current_handler_result() - return document - RUN.terminating_scopes[scope] = true - CHARGE_TERMINATION_MARKER_WRITE() - CHARGE_FATAL_OVERHEAD() - document = DIRECT_WRITE(document, - JOIN_SCOPE_PATH(scope, "/contracts/terminated"), - ProcessingTerminatedMarker(cause="fatal", reason=reason)) - event = DocumentProcessingTerminated(cause="fatal", reason=reason) - document = DELIVER_LIFECYCLE(document, scope, event) - RUN.terminated_scopes[scope] = true - clear_fifo(scope) - if scope == "/": - if not RUN.root_fatal_error_appended: - RUN.root_events.append(DocumentProcessingFatalError(reason=reason)) - RUN.root_fatal_error_appended = true - raise ROOT_FATAL_TERMINATION - return document -``` - -The pseudocode is informative. The observable state changes and ordering above are normative. - -If a termination helper raises `ROOT_GRACEFUL_TERMINATION` or `ROOT_FATAL_TERMINATION`, the raised control signal carries the current updated document. The top-level wrapper returns that updated document. This is pseudocode notation only; implementations may use exceptions, tagged returns, or another deterministic control-flow representation. - -`abort_current_handler_result()` means that the processor stops applying any remaining unapplied effects from the currently executing contract result. Effects already fully applied remain applied. No additional patches, Triggered emissions, or termination requests from that result are processed. - ---- - -## 12. Gas Accounting - -### 12.1 Philosophy and unit (normative) - -Gas is an abstract deterministic unit used to measure work. - -Processors MUST NOT base gas on wall-clock time, CPU model, memory pressure, I/O latency, scheduler behavior, or implementation-specific performance. - -Given the same input document, event, provider state, supported contract set, and deterministic contract implementations, all conforming processors MUST return the same `total_gas`. - -### 12.2 Accumulation (normative) - -`RUN.total_gas` MUST include: - -- all processor charges from this section; -- all explicit `consumeGas(units)` calls made by channels and handlers. - -`consumeGas(units)` MUST use a non-negative integer. Invalid gas amounts are deterministic runtime fatals. - -### 12.3 Scope management charges (normative) - -| Operation | Formula | Charge point | -|---|---:|---| -| Scope entry | `50 + 10 * depth` | On entry to `_PROCESS` for a scope. Root depth is 0. | -| Scope exit | `0` | On return from `_PROCESS`. | -| Initialization | `1000` | When first-run initialization starts for a scope. | - -`depth` is the number of embedded edges from root. - -Entering `_PROCESS` for an existing terminated scope still incurs the scope-entry charge. The terminated-marker check happens after scope entry and before any initialization, channel matching, lifecycle delivery, bridging, FIFO drain, or checkpoint work. - -### 12.4 Matching and contract-call charges (normative) - -| Operation | Formula | Charge point | -|---|---:|---| -| External channel match attempt | `5` per candidate tested | Each external channel candidate considered for an input event at a scope. | -| Handler call overhead | `50` | Immediately before executing each handler. | - -Explicit gas consumed by channel and handler code is added separately. - -### 12.5 Patch and cascade charges (normative) - -| Operation | Formula | Charge point | -|---|---:|---| -| Boundary check | `2` per patch | Before applying each handler/channel patch. | -| Patch `add` / `replace` | `20 + ceil(bytes / 100)` | After validation, before mutation. | -| Patch `remove` | `10` | After validation, before mutation. | -| Post-patch type soundness check | `5` per checked node | During `RESTORE_TYPE_SOUNDNESS`. | -| Cascade routing | `10` per participating scope | For each scope that receives the resulting Document Update. | - -For cascade-routing gas, a participating scope is an ancestor-or-origin scope that has at least one matching Document Update Channel for the changed path and therefore receives a Document Update delivery. - -For gas byte formulas, `bytes` is the UTF-8 byte length of the RFC 8785 canonical JSON representation of the node after `NORMALIZE_RUNTIME_NODE_FOR_INSERTION`, using selected-document form. It is not Content BlueId canonicalization and does not require resolving unrelated type chains. For `remove`, no `val` bytes are charged. - -Processor-managed initialization marker patches and generated type generalization writes are charged as patches and cascades. They are not charged for boundary checks because they are processor-internal and allowed to write their reserved or generated paths. - -### 12.6 Event, bridge, and FIFO charges (normative) - -| Operation | Formula | Charge point | -|---|---:|---| -| Emit event | `20 + ceil(bytes / 100)` | When `emitEvent(node)` succeeds. | -| Bridge child emission to parent | `10` per child emission delivered to at least one matching Embedded Node Channel | Before delivering the node to Embedded Node Channel handlers. | -| Drain FIFO event | `10` per dequeued event | Immediately before Triggered Channel handler routing. | - -`bytes` is the UTF-8 byte length of the emitted event node's RFC 8785 canonical JSON representation after `NORMALIZE_RUNTIME_NODE_FOR_INSERTION`, using selected-document form. - -The same gas-byte view applies to emitted event nodes after event validation and normalization. - -Emit-event gas is charged only after the emitted node has passed Blue Language validity checks. An invalid emitted event causes fatal termination but does not incur the successful emit-event charge. - -Bridge gas is not charged merely because a child emission was recorded. It is charged once per recorded child emission that is actually delivered to at least one matching Embedded Node Channel in the parent, regardless of how many matching channels receive that emission. - -### 12.7 Direct Write and checkpoint charges (normative) - -| Operation | Formula | Charge point | -|---|---:|---| -| Lazy checkpoint creation | `0` | When creating an empty checkpoint before accepted external-channel newness evaluation. | -| Checkpoint read | `0` | When consulting a checkpoint. | -| Checkpoint update | `20` | After successful external channel processing. | -| Termination marker Direct Write | `20` | When writing `contracts/terminated`. | - -Direct Writes never trigger Document Update cascades. - -### 12.8 Lifecycle and termination charges (normative) - -| Operation | Formula | Charge point | -|---|---:|---| -| Lifecycle delivery | `30` | Per `DELIVER_LIFECYCLE` call, before lifecycle handlers. | -| Graceful termination overhead | `0` | Marker write and lifecycle delivery are charged separately. | -| Fatal termination overhead | `100` | On fatal termination, in addition to marker write and lifecycle delivery. | -| Must-understand capability failure | `0` | Pre-execution failure. | - -A fatal termination step costs at least `150` gas: marker Direct Write `20`, lifecycle delivery `30`, and fatal overhead `100`, plus any handler, patch, cascade, or emitted-event costs already incurred. - -A graceful termination step costs at least `50` gas: marker Direct Write `20` plus lifecycle delivery `30`. - -### 12.9 Accounting-only default (normative) - -This specification defines gas accounting, not enforcement. - -Absent an active supported gas policy, a processor MUST NOT skip work, change behavior, or terminate solely because gas is high. It records and returns `total_gas`. - -A separate supported policy marker MAY define budgets and overrun behavior. Such policies MUST be deterministic. If an unsupported gas policy contract is present in an active scope, must-understand rules apply. - -### 12.10 Gas examples (informative) - -Already-initialized root with one accepted external channel, one small `replace`, one matching root Document Update handler, and a successful checkpoint update: - -```text -scope entry 50 -channel match 5 -handler overhead 50 -boundary check 2 -replace 21 # about 1-100 bytes -cascade routing 10 -update handler 50 -checkpoint update 20 ---------------------- -minimum total 208 # plus explicit consumeGas -``` - -Already-initialized root reached through one accepted external channel whose handler violates the boundary before any checkpoint update: - -```text -scope entry 50 -channel match 5 -handler overhead 50 -boundary check 2 -termination marker 20 -lifecycle delivery 30 -fatal overhead 100 ------------------------ -minimum total 257 -``` - -Exact totals depend on the number of channels tested, handlers invoked, patch sizes, cascades, emissions, bridges, lifecycle handlers, initialization work, and explicit contract gas. - ---- - -## 13. Processor vs Feeder - -### 13.1 Feeder responsibilities (informative) - -A feeder is an external component that may: - -- collect events from users, networks, ledgers, queues, or sensors; -- order or batch events; -- retry delivery; -- deduplicate at the transport level; -- attach signatures or proofs; -- decide which document receives which event. - -Feeder behavior is outside this specification. - -### 13.2 Processor responsibilities (normative) - -Given one `document` and one `event`, the processor executes exactly the rules in this specification. - -The processor MUST NOT assume that the feeder has removed stale or duplicate events. External channel checkpoints provide deterministic in-document gating. - -### 13.3 Event ordering (normative) - -The processor handles only the single event supplied to one invocation. Ordering across multiple invocations is outside this specification except where persisted state, such as checkpoints and document mutations, affects later invocations. - ---- - -## 14. Security, Determinism, and Sandboxing - -### 14.1 Deterministic execution (normative) - -Contract execution MUST be deterministic. A contract MUST NOT read or depend on: - -- wall-clock time; -- process uptime; -- random numbers; -- CPU speed, thread scheduling, or memory addresses; -- ambient environment variables; -- network calls; -- filesystem state not represented as deterministic provider content; -- hidden mutable global state. - -All data affecting contract behavior MUST be present in the selected document, the delivered event payload, supported contract content, deterministic provider content verified by BlueId, or explicit processor context defined by this specification. - -### 14.2 Side-effect isolation (normative) - -Handlers and channels MUST NOT perform external side effects. Their only observable effects are the processor operations defined here. - -A conforming processor SHOULD sandbox contract implementations to enforce this boundary. - -Informative examples of common enforcement strategies include a pure interpreter, deterministic WASM with disabled host imports, capability-safe host APIs, frozen/immutable input objects, deterministic gas/fuel counters, and denying filesystem, network, clock, or random access unless represented as verified provider content. - -### 14.3 Payload immutability (normative) - -Delivered payloads, snapshots, and context objects are read-only. Contracts MUST NOT mutate them. - -If a contract implementation attempts mutation and the processor can detect it, the processor SHOULD treat it as a deterministic runtime fatal. If the processor prevents mutation by construction, no fatal is needed. - -### 14.4 Resource exhaustion (normative) - -Processors SHOULD expose implementation limits for: - -- maximum recursion depth; -- maximum embedded scopes per run; -- maximum FIFO length; -- maximum emitted events per run; -- maximum patch size; -- maximum canonicalization size for gas measurement; -- maximum provider materialization depth. - -If a limit is exceeded, the processor MUST handle it deterministically, normally as a runtime fatal at the affected scope unless a supported policy specifies otherwise. - -### 14.5 Provider safety (normative) - -Provider content used for contract type resolution, Content BlueId calculation, or event identity MUST be verified against its BlueId according to the Blue Language specification. - -A processor MUST NOT execute unverified provider content as a contract. - -### 14.6 Authorization out of scope (informative) - -This specification does not decide who is allowed to submit events or install contracts. Authorization can be expressed by supported contract types or by feeder policy, but the processor semantics here remain deterministic. - ---- - -## 15. Conformance Checklist and Test Vectors - -### 15.1 Conformance checklist (normative) - -A compliant Blue Contracts and Processor 1.0 implementation MUST satisfy the requirements below. - -**Inputs and capabilities** - -- Operate on Processing Documents, or preprocess Source Documents outside the runtime run. -- Reject non-object document roots before runtime as invalid Processing Documents. -- Do not require a fully Resolved View before `PROCESS` begins. -- Treat input events as read-only Blue nodes. -- Enforce must-understand before mutation for the initial active processing closure. -- Treat unsupported contracts discovered after mutation as runtime fatal at the discovering scope. -- Use canonical runtime type registry BlueIds for processor-managed contracts. - -**Contract model** - -- Discover runtime contracts from materialized selected-document `contracts` entries only, unless a profile explicitly extends runtime discovery. -- Execute contracts only in active scopes. -- Keep contracts scope-local. -- Sort channels and handlers by `(order, key)`. -- Use dispatch snapshots so in-flight handler/channel lists and executable contract content are not changed by contract mutations. -- Normalize contract results before applying effects. -- Buffer handler/channel effects during execution and apply normalized results only through the specified gas, patches, events, termination order. -- Enforce same-scope handler binding. -- Enforce reserved processor key compatibility and write protection. -- Allow handler/channel mutation of `contracts/embedded.paths` only through the narrow exception in §3.7. -- Treat delivered payloads and snapshots as immutable. -- Enforce contract-map key grammar. - -**Embedded traversal and isolation** - -- Read **Process Embedded** paths dynamically and re-read after each child. -- Process each child path at most once per parent invocation. -- Enforce no resurrection. -- Enforce boundary rules, self-root mutation forbidden, and root target forbidden. -- Implement balloon cut-off when an active child root is removed or replaced. - -**Initialization and lifecycle** - -- Initialize a scope only when `contracts/initialized` is absent. -- Publish **Document Processing Initiated** before writing the initialized marker. -- Write **Processing Initialized Marker** by processor-managed patch that triggers Document Update cascade. -- Do not create checkpoints during initialization. -- Honor pre-existing **Processing Terminated Marker** by making the scope inactive. - -**Patch semantics** - -- Support only `add`, `replace`, and `remove`. -- Use absolute Blue Runtime Pointers. -- Auto-materialize missing intermediate objects for `add` and `replace`. -- Support array append and insert semantics. -- Reject array out-of-range, malformed pointers, missing `val`, invalid `val`, and unsupported operations. -- Normalize every inserted patch value using `NORMALIZE_RUNTIME_NODE_FOR_INSERTION`. -- Restore post-patch type soundness before exposing a Document Update cascade. -- Apply dynamic type generalization when required and permitted by policy;

processor-managed channels are not gated. -- Store the normalized checkpoint subject by default in `lastEvents[channelKey]` under the raw contract-map key after successful processing, unless the channel type defines a different checkpoint subject. -- Apply the effective checkpoint identity mode: `contentBlueId` by default, `nodeBlueId` only for valid BlueId Input, or `channelDefined` for concrete supported channel types. -- Create missing reserved object containers required by processor-managed Direct Writes. -- Leave checkpoint unchanged for stale events and channels that terminate the scope. -- Enforce checkpoint tamper resistance. - -**Termination and failures** - -- Return capability failure with no mutation, no events, and zero gas. -- On scope termination, Direct Write **Processing Terminated Marker**, publish **Document Processing Terminated**, deactivate scope, and drop FIFO. -- Enforce single-entry termination per scope per invocation. -- Non-root fatal does not escalate by default. -- Root graceful ends the run with termination lifecycle in outbox. -- Root fatal appends **Document Processing Fatal Error** and aborts the run. -- Classify conformance-visible failures using Appendix C categories. -- Use the termination Direct Write fallback exactly once when malformed containers prevent writing `contracts/terminated`. - -**Gas** - -- Apply all formulas in §12 deterministically. -- Charge cascade routing only for participating scopes that receive Document Update delivery. -- Charge bridge gas once per child emission delivered to at least one matching Embedded Node Channel. -- Charge post-patch type soundness checks and generated generalization writes under §6.10.4 and §12. -- Use the runtime insertion normalization byte view for patch and emitted-event byte charges. -- Include explicit `consumeGas` units. -- Do not enforce budgets unless a supported deterministic policy says so. - -### 15.2 Behavior-defining test vectors (normative) - -The following vectors are normative. Machine-readable fixtures MAY add exact document inputs, event inputs, and expected gas totals. - -**T1 — Dynamic embedded list** -Root declares embedded paths `/a`, `/b`. While processing `/a`, a root-scope handler is invoked by a Document Update cascade or another root-scope delivery and patches only `/contracts/embedded/paths`, removing `/b` and adding `/c`. The handler does not replace `contracts/embedded` as a whole, change `contracts/embedded/type`, or write any other field under `contracts/embedded`. -**Then:** after `/a`, the processor re-reads paths and visits `/c`; `/b` is skipped if it no longer exists. - -**T2 — Boundary enforcement** -Root attempts `replace /a/x` while `/a` is an active embedded child. -**Then:** root terminates fatally; `contracts/terminated` is written with cause `fatal`; **Document Processing Fatal Error** is appended to root outbox; run aborts. - -**T3 — Initialization once** -First run at `/a` has no initialized marker. -**Then:** **Document Processing Initiated** is published, **Processing Initialized Marker** is patched into `/a/contracts/initialized`, and that patch triggers a Document Update cascade. Later runs do not reinitialize `/a`. - -**T4 — Update cascades: absolute match and relative payload** -A handler at `/a` applies `replace /a/z/k`. Root has a Document Update Channel watching `/a/z`. -**Then:** at `/a`, payload path is `/z/k`; at root, payload path is `/a/z/k`; matching uses absolute paths. - -**T5 — Cascade emissions are enqueued, not delivered** -A patch at `/a/b` causes a Document Update handler at `/a` to emit `E`. -**Then:** `E` is recorded under `/a` and enqueued; it is delivered only during `/a` Phase 5 if `/a` has a Triggered Event Channel. - -**T6 — Triggered FIFO order** -A handler at `/a` emits `E1`, then `E2`. `/a` has a Triggered Event Channel. -**Then:** `/a` drains `E1` then `E2`; events emitted during drain append to the tail. - -**T7 — Bridging child emissions** -Child `/x` emits events during its run. Parent has an Embedded Node Channel for `/x`. -**Then:** parent bridges `/x` emissions in recorded order during Phase 4, before parent FIFO drain. - -**T8 — Checkpoint gating** -Two external channels accept the same event; one event is stale under its channel policy, one is new. -**Then:** stale channel handlers are skipped; new channel handlers run; only the new channel's checkpoint entry is updated. - -**T9 — Capability failure** -The initial active processing closure contains an unsupported contract type. -**Then:** processor returns must-understand capability failure; document unchanged; no lifecycle events; total gas `0`. - -**T10 — No accepted external channel** -All external channel candidates reject the event in every active scope. -**Then:** document changes only if first-run initialization is required; otherwise no patches, emissions, or checkpoint creation occur except measured channel-match gas. - -**T11 — Object auto-materialization** -A handler applies `add /a/b/c { ... }` where `/a` exists and `/a/b` does not. -**Then:** processor creates `/a/b` as an object and writes `/a/b/c`; one Document Update cascade runs for `/a/b/c`. - -**T12 — Array append and insert** -Given `/a/items: ["x", "y"]`, `add /a/items/- "z"` yields `["x", "y", "z"]`; `add /a/items/1 "q"` yields `["x", "q", "y"]`. -**Then:** each patch triggers one cascade. - -**T13 — Deterministic runtime fatal for invalid patch** -`replace /a/items/7 "z"` when length is less than 8, or `remove /a/missingKey`. -**Then:** executing scope terminates fatally; root fatal only if executing scope is root. - -**T14 — Scope-relative payload** -Patch replaces `/a/b/x`. -**Then:** payload path is `/x` at `/a/b`, `/b/x` at `/a`, and `/a/b/x` at root. - -**T15 — Root lifecycle inclusion** -First processing at root publishes **Document Processing Initiated**. Later root fatal occurs. -**Then:** root outbox includes root lifecycle events and **Document Processing Fatal Error**. - -**T16 — Local delivery depends on Triggered Channel presence** -During a cascade at `/a`, a handler emits `E`. `/a` lacks Triggered Event Channel. -**Then:** `E` is recorded and bridgeable, but not locally delivered at `/a`. - -**T17 — Uniform event per scope** -Multiple Document Update Channels at `/a` match the same patch. -**Then:** all handlers at `/a` receive the same immutable Document Update payload object. - -**T18 — Lazy checkpoint creation** -A scope has an accepted external channel delivery and lacks `contracts/checkpoint`. -**Then:** before newness evaluation, the processor Direct Writes an empty checkpoint; no Document Update is emitted. - -**T19 — Duplicate checkpoint marker** -A scope contains a **Channel Event Checkpoint** under a non-reserved key in addition to `contracts/checkpoint`. -**Then:** runtime fatal. - -**T20 — Stale external event** -`lastEvents.testChannel` holds `E_old`; incoming event is not new under `testChannel` policy. -**Then:** channel handlers are skipped; checkpoint unchanged. - -**T21 — Checkpoint updated after success** -A new external event on a default-subject `testChannel` is processed successfully. -**Then:** `lastEvents.testChannel` is Direct Written to the entire incoming event node; no Document Update is emitted. - -**T22 — Multiple external channels** -Two external channels accept the event and are both new. -**Then:** they run in `(order, key)` order; each updates its own checkpoint key after successful processing. - -**T23 — Self-root mutation forbidden** -While executing at `/a`, a contract attempts `remove /a`, `replace /a`, or `add /a`. -**Then:** fatal termination at `/a`. - -**T24 — Root-document mutation forbidden** -Any contract targets `/` with any patch operation. -**Then:** fatal termination at the executing scope; if root, run aborts with fatal outbox. - -**T25 — Balloon cut-off** -While `/b` is being processed, a parent watcher removes `/b`. -**Then:** current effect completes; no further work, handlers, or drain occur for `/b`; already recorded emissions remain bridgeable; re-adding `/b` in the same run does not schedule it again. - -**T26 — Termination is final in a run** -A scope terminates gracefully; later a handler at that scope would emit or patch. -**Then:** further patch/emit from that scope are no-ops. - -**T27 — Child fatal does not escalate by default** -`/a` terminates fatally. -**Then:** `/a` is marked terminated; parent continues; child termination lifecycle is bridgeable. - -**T28 — Child graceful termination bridges lifecycle** -`/a` terminates gracefully. -**Then:** parent may observe **Document Processing Terminated** via Embedded Node Channel if configured. - -**T29 — Root graceful termination ends run** -Root terminates gracefully. -**Then:** run ends; root outbox includes **Document Processing Terminated**. - -**T30 — Root fatal termination ends run with fatal outbox** -Root terminates fatally. -**Then:** run ends; root outbox includes **Document Processing Terminated** followed by **Document Processing Fatal Error**. - -**T31 — Pre-existing terminated marker** -An embedded scope has a valid `contracts/terminated` marker before processing. -**Then:** processor charges scope entry for entering and recognizing that scope, but does not initialize, match, run, bridge, drain, or create checkpoint state for that scope. - -**T32 — Default content-idempotent checkpoint policy** -An external channel defines no custom newness policy. Incoming event has same Content BlueId as stored previous event. -**Then:** event is stale and handlers are skipped. - -**T33 — Reserved-key tamper** -A handler attempts `replace /contracts/checkpoint/lastEvents/x ...`. -**Then:** executing scope terminates fatally. - -**T34 — Direct Write does not cascade** -Checkpoint creation, checkpoint update, or termination marker write occurs. -**Then:** no Document Update event is emitted solely for the Direct Write. - -**T35 — Unsupported contract introduced mid-run** -A handler patches a supported scope to add an unsupported contract type, and a later step attempts to execute that scope. -**Then:** the discovering scope terminates fatally, not capability-fails retroactively. - -**T36 — Processing Document is not eagerly resolved** -A document has a contract whose type reference can be resolved, but unrelated type references elsewhere are unavailable. -**Then:** processing may proceed unless the unavailable reference is needed for contract discovery, contract execution, Content BlueId calculation, or event identity. - -**T37 — Termination reentrancy** -A termination lifecycle handler calls `terminate(...)` again. -**Then:** exactly one terminated marker and one **Document Processing Terminated** event are produced for that scope. - -**T38 — External channel payload type declaration** -An external channel declares `payloadType`. -**Then:** handler matching is against the channelized payload conforming to that type, not the original input event. - -**T39 — Candidate channel gas** -A scope has three external candidate channels; two reject and one accepts. -**Then:** channel match gas is charged for all three candidate evaluations. - -**T40 — Root path joining** -Root initialization or root termination writes a processor marker. -**Then:** the processor writes `/contracts/initialized` or `/contracts/terminated`, never `//contracts/initialized` or `//contracts/terminated`. - -**T41 — Rejected external candidates do not create checkpoint** -A scope has an external channel candidate that rejects the event and no accepted external channel. -**Then:** no checkpoint marker is lazily created. - -**T42 — Termination lifecycle fatal is deterministic** -A root graceful termination lifecycle handler causes a deterministic runtime fatal. -**Then:** the original terminated marker and **Document Processing Terminated** event are not duplicated; the root outbox contains **Document Processing Terminated** followed by exactly one **Document Processing Fatal Error**. - -**T43 — Type-derived contracts are not executed by core** -A scope's type contains a `contracts.audit` entry, but the selected document scope has no materialized `contracts.audit`. -**Then:** Blue Contracts 1.0 core does not execute `audit`. If a profile wants inherited runtime contracts, it must define that as an extension. - -**T44 — Contracts-map reserved-key bypass is forbidden** -A root handler attempts `replace /contracts` with a map omitting `checkpoint` or `initialized`. -**Then:** the executing scope terminates fatally, even though the patch did not directly target `/contracts/checkpoint` or `/contracts/initialized`. - -**T45 — Handler list snapshot** -Two handlers `H1` and `H2` are eligible for one delivery. `H1` removes `H2`'s contract entry. -**Then:** `H2` still runs for that delivery unless the scope is terminated or cut off. The removal affects later deliveries only. - -**T46 — External candidate snapshot** -External candidate `C1` runs before `C2`. `C1` removes `C2`'s contract entry. -**Then:** `C2` remains in the current Phase 3 candidate snapshot. Later invocations observe the removal. - -**T47 — Post-patch Document Update discovery** -A patch adds a Document Update Channel watching the changed path. -**Then:** that channel is eligible to receive the Document Update for the same patch, because discovery uses the post-patch Selected Document View. - -**T48 — Snapshotted executable handler content** -Two handlers `H1` and `H2` are eligible for one delivery. `H1` replaces `H2`'s contract body before `H2`'s turn. -**Then:** `H2` still executes using the snapshotted resolved contract content captured for that delivery. Later deliveries observe the replacement. - -**T49 — Direct Write creates missing reserved containers** -A root document has no `contracts` map. An accepted external channel requires checkpoint creation, or root termination requires writing `contracts/terminated`. -**Then:** the processor creates the required reserved object containers by Direct Write, emits no Document Update solely for those writes, and never writes `//contracts/...`. - -**T50 — Reserved-key preservation uses Blue-node equality** -A handler replaces `/contracts` with a serialization-different but canonically identical reserved marker subtree. -**Then:** the replacement is allowed only if all reserved processor keys and descendants are preserved as the same selected-document Blue nodes under Blue Language normalization; raw source byte equality is not used. - -**T51 — Embedded paths mutation exception** -A root-scope handler invoked by a Document Update cascade or other root-scope delivery during `/a` processing patches only `/contracts/embedded/paths` to remove `/b` and add `/c`. -**Then:** the patch is allowed if the Process Embedded marker remains valid; after `/a`, the processor re-reads paths and visits `/c`. - -**T52 — Embedded marker type remains protected** -A handler attempts to patch `/contracts/embedded/type`. -**Then:** the executing scope terminates fatally with `ReservedKeyWrite`. - -**T53 — Embedded marker whole replace remains protected** -A handler attempts to replace `/contracts/embedded` as a whole. -**Then:** the executing scope terminates fatally with `ReservedKeyWrite`. - -**T54 — Triggered channel discovery is per FIFO event** -A Triggered FIFO drain handles `E1`, and a handler during `E1` adds a Triggered Event Channel that matches `E2`. -**Then:** the new channel does not affect `E1`, but it is discoverable for later dequeued `E2`. - -**T55 — Embedded channel discovery is per child emission** -A parent bridges a child emission and a handler adds or removes an Embedded Node Channel during that bridge delivery. -**Then:** the mutation does not change the already-snapshotted emission delivery, but later emissions use fresh discovery. - -**T56 — Contract-map key grammar** -A scope contains contract-map keys `""`, `type`, or `value`. -**Then:** the keys are invalid when discovered in an active scope; a key containing `/` remains stored raw and is escaped only when constructing runtime pointers. - -**T57 — Checkpoint raw key storage** -An accepted external channel has contract key `orders/incoming`. -**Then:** the checkpoint object member key is `orders/incoming`; the pointer used for Direct Write escapes it as `orders~1incoming`. - -**T58 — Default checkpoint identity mode** -An external channel declares no checkpoint identity mode. -**Then:** newness compares Content BlueIds of normalized checkpoint subjects, and an authored `eventId` field has no special meaning unless the concrete channel defines it. - -**T59 — Node BlueId checkpoint identity mode** -An external channel selects `nodeBlueId` checkpoint identity mode and supplies a checkpoint subject that is not valid BlueId Input. -**Then:** processing fails deterministically with `CheckpointError`. - -**T60 — Effect buffering order** -A handler calls host APIs in the order `emitEvent(E)`, `applyPatch(P)`, `terminate(graceful)`. -**Then:** the normalized result applies explicit gas first, then patch `P` and its cascades, then records/enqueues `E`, then terminates. - -**T61 — Buffered effects are discarded on handler throw** -A handler buffers a patch and then throws before returning a valid result. -**Then:** the buffered patch is not committed; the executing scope terminates fatally with `HandlerExecutionError`. - -**T62 — Runtime insertion normalization** -A patch value is a bare scalar, a wrapped scalar, or a list containing a recursively empty object. -**Then:** the value is normalized under `NORMALIZE_RUNTIME_NODE_FOR_INSERTION` before insertion, gas-byte calculation, event identity, and downstream contract discovery. - -**T63 — Processor-emitted event instances carry type** -The processor emits Document Update, Document Processing Initiated, Document Processing Terminated, or Document Processing Fatal Error. -**Then:** the delivered event instance includes a `type` pure reference to the corresponding runtime event type BlueId. - -**T64 — Document Update null sentinels** -A patch adds a previously absent node or removes an existing node. -**Then:** delivered Document Update payloads use `before: null` or `after: null` as runtime absence sentinels; handlers observe them in the delivered payload even though Blue Language identity cleaning removes null object fields. - -**T65 — Initialization Content BlueId timing** -A scope initializes for the first time. -**Then:** `documentId` is the scope Content BlueId immediately after Phase 1 embedded processing and before the initialized marker is written. - -**T66 — Termination Direct Write fallback** -The processor must write a terminated marker but the scope's existing `contracts` container is malformed. -**Then:** it makes one fallback attempt as defined in §11.4; if fallback also fails, the run aborts with `TerminationError`. - -**T67 — Extension role contract is unsupported, not inert** -A contract's effective type is a subtype of Contract but not Channel, Handler, or Marker, and the processor does not support that exact extension role type BlueId. -**Then:** the contract is unsupported and subject to must-understand or runtime-fatal rules. - -**G1 — Fixed value violation generalizes nearest node type** -Given `/price` typed `Price in EUR`, a patch replaces `/price/currency` with `USD`, and `/price` conforms to ancestor type `Price`. -**Then:** the processor generalizes `/price/type` to `Price` when policy permits. - -**G2 — Generalization propagates to parent** -The root type requires `/price: Price in EUR`; `/price` generalizes to `Price`; and the root conforms only to ancestor type `Global Product`. -**Then:** the processor also generalizes root type to the nearest valid permitted parent type. - -**G3 — Policy floor prevents over-generalization** -A Type Generalization Policy rule requires root to remain equal to or a subtype of `Bank Transfer PayNote`. -**Then:** a patch that would require generalizing above that type is runtime fatal with `GeneralizationRejected` or `GeneralizationNoValidType`. - -**G4 — Reject mode prevents generalization** -The effective generalization policy for a changed path is `reject`. -**Then:** a patch that would require generalization is runtime fatal and no tentative patch or generated write is committed. - -**G5 — Generalization writes produce Document Updates** -A patch requires generated writes to child and parent `/type` fields. -**Then:** the requested patch cascade is delivered first, followed by generated type-write cascades in deepest-to-root order. - -**G6 — Embedded child cannot generalize ancestor** -A patch executing inside an embedded child would require generalizing the parent scope to restore global type soundness. -**Then:** the child patch is runtime fatal unless the ancestor itself issued the patch or a future extension explicitly permits cross-scope generalization. - -### 15.3 Machine-readable fixtures (normative) - -The Blue Contracts 1.0 conformance suite MUST publish machine-readable fixtures for the vectors above. - -The canonical Blue Contracts 1.0 fixture package is part of the Blue Contracts 1.0 release artifact and is versioned with this specification. The release authority MUST publish the fixture package identity, either as a BlueId or as a content-addressed release artifact digest. This prose specification intentionally does not include placeholder fixture BlueIds. - -The fixture package identity for this Blue Contracts and Processor 1.0 publication is: - -```text -sha256:2f197ca3bbdc41b75e772777cc48e51019754347e1bee26b5f3209b71d9bd9ca -``` - -A fixture with `operation: processDocument` is executable unless it explicitly sets `informativeOnly: true`. - -An executable process fixture MUST include enough machine-readable input and expected output to be run by an independent implementation. At minimum it MUST include: - -- `initialDocument`; -- `event`; -- either `mockRuntime`, concrete supported runtime contract types, or a declared deterministic `processorCapabilities` entry sufficient to execute the fixture; -- at least one machine-checkable expected result such as `expectedStatus`, `expectedDocument`, `expectedDocumentPaths`, `expectedAbsentDocumentPaths`, `expectedRootEvents`, `expectedRootEventTypes`, `expectedTotalGas`, `expectedErrorCategory`, `expectedErrorCategories`, or `expectedNoDocumentMutation`. - -The free-text `assertions` field is informative only. It MUST NOT be the only evidence for a conformance-required executable fixture. - -A fixture that contains only prose assertions MUST set `informativeOnly: true` and MUST NOT be counted as passing executable conformance coverage. - -The release fixture manifest is the canonical list of required executable fixtures for this Blue Contracts 1.0 release. A conforming implementation MUST report the fixture package identity it passes. Release tooling MUST verify that every manifest entry exists, every fixture ID is unique, and no unlisted fixture YAML files are present. - -Registry fixtures, pointer utility fixtures, and other non-`processDocument` fixtures MAY use operation-specific inputs instead of `initialDocument` and `event`. The executable input requirements above apply only to `operation: processDocument`. - -The fixture package identity algorithm is part of the release artifact. To calculate `fixturePackageIdentity`: - -1. Normalize all line endings to LF. -2. Start the digest with the UTF-8 bytes of `manifest.yaml\n`. -3. Read `manifest.yaml`, replace the line beginning `fixturePackageIdentity:` with `fixturePackageIdentity: ""`, normalize line endings, and append those bytes. -4. Iterate manifest `fixtures` in manifest order. Do not sort paths separately. -5. For each fixture, append the UTF-8 bytes of `\n--- \n`, then append the fixture file bytes after LF line-ending normalization. -6. Encode the SHA-256 digest as lowercase hexadecimal prefixed by `sha256:`. - -Fixtures SHOULD include: - -```yaml -id: T21 -category: Checkpoint -initialDocument: ... -event: ... -expectedDocument: ... -expectedRootEvents: ... -expectedTotalGas: ... -``` - -Exact gas fixtures MUST specify contract implementations or mock contract result functions so that handler gas and emitted effects are deterministic. - -Fixture packages MUST include registry conformance fixtures proving that: - -- the Contract registry node hashes to its published BlueId; -- the Channel registry node hashes to its published BlueId; -- the Handler registry node hashes to its published BlueId; -- the Marker registry node hashes to its published BlueId; -- the Json Patch Entry registry node hashes to its published BlueId; -- the Contract Execution Result registry node hashes to its published BlueId; -- the Process Embedded registry node hashes to its published BlueId; -- the Processing Initialized Marker registry node hashes to its published BlueId; -- the Processing Terminated Marker registry node hashes to its published BlueId; -- the Channel Event Checkpoint registry node hashes to its published BlueId; -- the Type Generalization Policy registry node hashes to its published BlueId; -- the Type Generalization Rule registry node hashes to its published BlueId; -- the Document Update Channel registry node hashes to its published BlueId; -- the Triggered Event Channel registry node hashes to its published BlueId; -- the Lifecycle Event Channel registry node hashes to its published BlueId; -- the Embedded Node Channel registry node hashes to its published BlueId; -- the Document Update event registry node hashes to its published BlueId; -- the Document Processing Initiated event registry node hashes to its published BlueId; -- the Document Processing Terminated event registry node hashes to its published BlueId; -- the Document Processing Fatal Error event registry node hashes to its published BlueId; -- documentId fields use Text with BlueId-string semantics unless a formal canonical BlueId type is intentionally published; -- changing a processor-managed runtime type `description` changes the node BlueId. - -The Blue Contracts runtime registry manifest MUST make identity-bearing descriptions explicit. Each entry in the registry manifest MUST identify the registry kind, specification version, entry key, exact registry source node path, the exact preprocessed/canonical node used for BlueId calculation or deterministic preprocessing rule, published BlueId, conformance fixture package identity, and `semanticDescriptionIdentityBearing: true`. - -Release checks MUST verify that: - -- registry nodes are loaded from files, not reconstructed from implementation constants; -- registry file content hashes to the published BlueIds; -- runtime constants equal the calculated registry BlueIds; -- no canonical registry node is edited without updating its BlueId and fixture package identity; -- generated documentation is derived from registry nodes, or explicitly marked non-canonical. - -Fixture packages MAY use the following portable mock runtime format: - -```yaml -id: Txx -category: ... -initialDocument: ... -event: ... -mockRuntime: - channels: - - contract: /contracts/incoming - calls: - - when: - event: any - accepted: true - payload: - $event: true - gasConsumed: 0 - - contract: /a/contracts/orders - calls: - - when: - eventContentBlueId: "" - accepted: true - payload: - type: Example Payload - gasConsumed: 0 - termination: null - handlers: - - contract: /contracts/saveName - calls: - - when: - channelKey: incoming - payload: any - result: - gasConsumed: 0 - patches: - - op: replace - path: /name - val: Alice - triggeredEvents: [] - termination: null -expectedDocument: ... -expectedRootEvents: ... -expectedTotalGas: ... -``` - -Normative fixture rules: - -- `contract` is an absolute pointer to a contract entry. -- Calls are consumed in order. -- For channel mock calls, `accepted` is required. -- If `accepted: true`, `payload` is required unless the channel terminates before delivery. -- If `accepted: false`, `payload` MUST be absent. -- `gasConsumed` defaults to `0`. -- `patches` and `triggeredEvents` default to `[]`. -- `termination` defaults to `null` and may be `null` or `{ cause: graceful|fatal, reason?: Text }`. -- Handler mock `result` uses the abstract **Contract Execution Result** fields. -- `payload: { $event: true }` means the original input event node. -- Matchers such as `any`, `eventContentBlueId`, and `payload` are fixture matcher syntax, not Blue content. -- A mock result MUST NOT grant a contract effects outside its role unless the fixture explicitly declares a profile extension. -- A fixture is invalid if a channel or handler call occurs with no matching mock call. -- `processorCapabilities` names deterministic fixture-harness capabilities required to execute the fixture. A conforming implementation may satisfy a capability natively or through a test harness, but it MUST report unsupported capabilities as fixture execution failures. -- `typeGraph` is fixture provider syntax for dynamic type generalization and type-soundness fixtures. It maps fixture type names to exact BlueId strings and parent relationships used by the conformance runner's provider. -- `expectedNoDocumentMutation: true` means the selected document after the operation is semantically equal to `initialDocument` under the selected-document normalization rules. -- `expectedDocumentUpdateOrder` is a machine-checkable list of Document Update changed paths in delivery order when a fixture needs to prove cascade ordering. -- Error fixtures MAY use `expectedErrorCategory: ` when exactly one primary diagnostic is asserted. -- Error fixtures MAY use `expectedErrorCategories: [, ...]` when more than one category is acceptable. -- Fixtures that intentionally contain multiple independent errors MUST assert only failure, or MUST list all acceptable categories. -- This mock schema is for conformance fixtures only; it is not a contract language. - -### 15.4 Fixture harness capabilities (normative for fixtures) - -Fixture harness capabilities are deterministic conformance-fixture tools. They are not Blue Contracts core contract languages and MUST NOT be treated as canonical runtime registry types. - -`blue-contracts-fixture-scripted-runtime-v1` defines a scripted fixture runtime for channel and handler behavior. It recognizes fixture-only channel and handler contracts whose type BlueIds are declared by the fixture package or whose behavior is supplied by `mockRuntime`. These fixture-only types are not part of the canonical runtime registry. - -A scripted external channel accepts an event when its configured `mockRuntime.channels[].calls[].when` matcher matches and `accepted: true`. If a fixture marks a contract as a generic fixture external channel and supplies no more specific matcher, the channel accepts all events. A rejected channel call has `accepted: false` and MUST NOT supply `payload`. An accepted channel call supplies a channelized `payload`, optional non-negative `gasConsumed`, and optional `termination`. - -A scripted handler produces a **Contract Execution Result** from either `mockRuntime.handlers[].calls[].result` or fixture-only fields on the contract entry. The following fixture-only handler fields map to buffered result effects: - -| Field | Fixture meaning | -|---|---| -| `patches` | List of Json Patch Entry objects buffered as handler patches. | -| `triggeredEvents` | List of Blue event nodes buffered as emitted Triggered events. | -| `gasConsumed` | Non-negative explicit gas consumed by the contract. | -| `consumeGas` | Fixture shorthand for explicit gas or a host `consumeGas` API call. | -| `termination` | `null`, `graceful`, `fatal`, or `{ cause: graceful|fatal, reason?: Text }`. | -| `emitInvalidEvent` | Emits a deliberately invalid event for error fixtures. | -| `hostApiCalls` | Ordered fixture host API calls used to prove buffering semantics. | - -`hostApiCalls` supports these operations: - -```yaml -hostApiCalls: - - emitEvent: - - applyPatch: { op: replace, path: /x, val: y } - - consumeGas: 5 - - terminate: { cause: graceful, reason: done } - - throw: { category: HandlerExecutionError } -``` - -These calls are fixture-harness host API calls. They are buffered according to §3.11 and are not immediate side effects. A `throw` aborts the current contract call before a valid result is returned; effects buffered by that throwing call are discarded unless a fixture explicitly says otherwise. - -The scripted runtime also defines these helper fields used by the release fixture package: - -| Field | Fixture meaning | -|---|---| -| `addDocumentUpdateChannelAt` | Fixture shorthand for a handler patch that installs a Document Update Channel at the given runtime pointer. | -| `documentUpdatePath` | Path value used with `addDocumentUpdateChannelAt` for the installed channel's watched `path`. | -| `childEmissions` | Fixture-provided recorded child emissions for Embedded Node bridge-order fixtures. | -| `bridgeMutations` | Fixture-provided mutations that occur during bridge delivery to test per-emission snapshots. | -| `forcedFatal` | Fixture instruction that forces a deterministic runtime fatal at the given scope. | -| `orderLog` | Ordinary fixture document field used to record observable ordering when a fixture expects it. | - -Matchers under `when` are fixture matcher syntax. `event: any` matches any Processing Event. `payload: any` matches any channelized payload. `eventContentBlueId` matches the Content BlueId of the normalized Processing Event. Exact map/list/scalar matcher values match by Blue node equality after runtime insertion normalization. - -`blue-contracts-fixture-type-graph-v1` defines a fixture provider for dynamic type generalization and type-soundness tests. It is fixture provider syntax only, not canonical Blue type syntax. - -```yaml -typeGraph: - Price: - blueId: - PriceInEUR: - blueId: - parent: Price - fixedValues: - /currency: EUR - Product: - blueId: - fields: - /price: - type: Price -``` - -`blueId` is the type identity used in fixture documents. `parent` defines the type-chain parent used for nearest-valid generalization. `fixedValues` defines path/value invariants. `fields` defines child-type constraints used for parent revalidation. Fixture paths in `typeGraph` are Blue Runtime Pointers unless stated otherwise. - -### 15.5 Fixture assertion fields (normative for fixtures) - -Any fixture field beginning with `expected` that is not defined here or in an operation-specific fixture manifest schema is invalid. - -| Field | Meaning | -|---|---| -| `expectedStatus` | Abstract fixture status: `success`, `runtime-fatal`, `capability-failure`, `invalid-processing-document`, or `invalid-input`. `invalid-processing-document` is the preferred fixture status when the selected document is not valid enough to enter runtime; `invalid-input` remains available for invalid event, fixture, or processor API input cases. | -| `expectedCapabilityFailure` | Boolean legacy assertion. If true, implies capability failure with no mutation, no gas, and no root events unless explicitly overridden. | -| `expectedNoDocumentMutation` | Final selected document is semantically equal to `initialDocument` after selected-document normalization. | -| `expectedDocument` | Exact selected document expected after the operation. | -| `expectedDocumentPaths` | Map from Blue Runtime Pointer to expected Blue node/value shape in the final selected document. | -| `expectedDocumentPathExists` | List of Blue Runtime Pointers that must exist in the final selected document. | -| `expectedDocumentPathValues` | List form of path/value assertions in the final selected document. | -| `expectedAbsentDocumentPaths` | Blue Runtime Pointers that must not exist in the final selected document. | -| `expectedAbsentDocumentPathValues` | Path/value pairs that must not match in the final selected document. | -| `expectedDocumentUpdates` | Expected Document Update payload assertions. | -| `expectedDocumentUpdateOrder` | Ordered list of changed paths for Document Update deliveries. | -| `expectedRootEvents` | Exact root outbox events. | -| `expectedRootEventTypes` | Ordered root event type BlueIds or symbolic fixture aliases. | -| `expectedRootEventPathValues` | Path/value assertions inside root outbox events. | -| `expectedRootEventCount` | Exact root outbox event count. | -| `expectedProcessorEventTypes` | Expected processor-emitted event type BlueIds by symbolic event name. | -| `expectedTotalGas` | Exact total gas. | -| `expectedExactGas` | Alias for exact total gas. A fixture MUST NOT use both `expectedTotalGas` and `expectedExactGas` unless they are equal. | -| `expectedTotalGasMin` | Lower bound on total gas. It is allowed only for non-exact smoke or performance-tolerant fixtures. | -| `expectedErrorCategory` | Exact diagnostic category. Fixture should isolate one primary error. | -| `expectedErrorCategories` | List of acceptable diagnostic categories for intentionally ambiguous multi-error cases. | -| `expectedFailureReasonContains` | Legacy substring check for diagnostic text. It is weaker than `expectedErrorCategory` and SHOULD NOT be used by new fixtures unless no category is stable. | -| `expectedCheckpointLastEvents` | Expected checkpoint subjects under raw channel keys in `lastEvents`. | -| `expectedRuntimeInsertionNormalizedValues` | Assertions about selected-document form after `NORMALIZE_RUNTIME_NODE_FOR_INSERTION`. | -| `expectedGasByteView` | Assertion describing which normalized form is used for patch or emitted-event gas byte calculation. | -| `expectedEffectApplicationOrder` | Ordered observable effect labels proving buffered effect order. | -| `expectedStoredObjectKeys` | Raw object keys stored in selected document at the given path. | -| `expectedEmbeddedDeliveryOrder` | Exact embedded scope processing or bridge delivery order. | -| `expectedTriggeredDeliveryOrder` | Exact Triggered FIFO event/channel delivery order. | -| `expectedTriggeredFifoAfterDocumentUpdates` | Boolean assertion that Triggered FIFO drain occurs only after all requested and generated Document Update cascades in the fixture. | -| `expectedPointerReads` | Expected runtime-pointer read paths used by pointer utility fixtures. | -| `expectedPointerWrites` | Expected runtime-pointer write paths used by pointer utility or Direct Write fixtures. | -| `expectedInitializationContentBlueIdInput` | Expected input/timing used to calculate initialization Content BlueId. | -| `expectedTerminationFallback` | Expected termination Direct Write fallback behavior. | -| `expectedBlueId` | Expected BlueId for registry or BlueId-calculation fixtures. | -| `expectedOriginalBlueId` | Expected original BlueId before mutation in identity-change fixtures. | -| `expectedRuntimeBlueIds` | Map of runtime type constants to expected registry BlueIds. | -| `expectedValid` | Boolean validity result for pointer utility or validation fixtures. | -| `expectedDescendantOrEqual` | Boolean result for runtime-pointer descendant-or-equal utility fixtures. | - ---- - -## 16. Worked Examples - -### 16.1 Minimal external event handler (informative) - -```yaml -contracts: - incoming: - type: Example External Channel - order: 0 - saveName: - type: Example Patch Handler - channel: incoming - patch: - op: replace - path: /name - val: Alice -``` - -When the `incoming` channel accepts an event, `saveName` patches `/name`. The patch triggers a Document Update cascade from root to root. - -### 16.2 Embedded child event bridge (informative) - -```yaml -contracts: - embedded: - type: Process Embedded - paths: [/payment] - paymentEvents: - type: Embedded Node Channel - childPath: /payment - forwardPayment: - type: Example Forward Handler - channel: paymentEvents - -payment: - contracts: - incoming: - type: Example External Channel - emitReceipt: - type: Example Emit Handler - channel: incoming -``` - -The root processes `/payment` first. If `/payment` emits a receipt event, root's `paymentEvents` channel bridges it in Phase 4. `forwardPayment` may re-emit a root-scope event, which is returned in root `triggered_events` and can be locally drained if root has a Triggered Event Channel. - -### 16.3 Document Update watcher (informative) - -```yaml -contracts: - watchAmount: - type: Document Update Channel - path: /amount - onAmount: - type: Example Audit Handler - channel: watchAmount -``` - -Any successful patch at `/amount` or below it triggers `watchAmount`. A patch at `/amount/currency` matches; a patch at `/status` does not. - -### 16.4 Checkpoint behavior (informative) - -```yaml -contracts: - orders: - type: Example Ordered Event Channel - handleOrder: - type: Example Order Handler - channel: orders -``` - -On first accepted external delivery requiring newness evaluation, the processor Direct Writes: - -```yaml -contracts: - checkpoint: - type: Channel Event Checkpoint - lastEvents: {} -``` - -If the event is new and `handleOrder` completes successfully, the processor Direct Writes: - -```yaml -contracts: - checkpoint: - type: Channel Event Checkpoint - lastEvents: - orders: checkpoint_subject(orders, event, delivery) -``` - -For the default checkpoint subject, this is the entire incoming event node. - -No Document Update is emitted for either Direct Write. - -### 16.5 End-to-end root update, audit, and checkpoint (informative) - -```yaml -contracts: - incoming: - type: Example External Channel - payloadType: Example Status Command - setStatus: - type: Example Patch Handler - channel: incoming - patch: - op: replace - path: /status - val: accepted - statusUpdates: - type: Document Update Channel - path: /status - emitAudit: - type: Example Audit Emit Handler - channel: statusUpdates - auditEvents: - type: Triggered Event Channel - storeAudit: - type: Example Audit Sink Handler - channel: auditEvents - -status: pending -``` - -Expected high-level order: - -1. During Phase 3, `incoming` is evaluated as an external channel candidate and accepts the input event. -2. If `contracts/checkpoint` is absent, the processor Direct Writes an empty checkpoint before newness evaluation. -3. `setStatus` receives the channelized payload and patches `/status` to `accepted`. -4. The patch produces a root Document Update cascade; `statusUpdates` receives the update payload. -5. `emitAudit` emits an audit event, which is recorded under root and appended to root's Triggered FIFO. -6. After successful external channel handling, the processor Direct Writes `lastEvents.incoming` to `checkpoint_subject(incoming, event, delivery)`, which is the incoming event node under the default checkpoint subject. -7. During Phase 5, `auditEvents` drains the audit event and `storeAudit` handles it. - -No exact BlueIds are shown here; concrete fixture packages provide exact canonical identities when needed. - ---- - -## Appendix A — Runtime Type Catalog - -Appendix A defines the canonical runtime types referenced throughout Blue Contracts and Processor 1.0. - -The canonical Blue runtime type registry supplies the exact Blue nodes and BlueIds for these types. The registry is the authority for exact string content, canonicalized node content, and published BlueIds. - -The canonical runtime type nodes below are intentionally self-describing. Their `description` fields are normative, identity-bearing content. Changing a canonical runtime description changes the node's BlueId and therefore defines a different runtime type. - -The YAML blocks in this appendix are intended registry source nodes. If a block uses symbolic core type aliases such as `Text`, `Integer`, `List`, or `Dictionary`, those aliases are resolved by the standard Blue Language baseline preprocessing environment before the canonical runtime registry BlueId is published. The registry release MUST publish the exact nodes and BlueIds it uses. - -Non-normative examples, rationale, translations, and implementation notes are not part of canonical runtime type nodes unless explicitly included in the registry node. - -### A.1 Base runtime type nodes - -#### Contract - -```yaml -name: Contract -description: > - Base Blue Contracts and Processor 1.0 runtime type for executable or - processor-interpreted declarations under an active scope's contracts map. - A Contract is scope-local, identity-bearing Blue content.

It cannot replace its own root and cannot patch siblings. - -### B.4 Do not let parents patch inside embedded children - -A parent can replace or remove a child root as a whole, but cannot patch inside it. - -### B.5 Do not emit Document Updates for Direct Writes - -Checkpoint creation, checkpoint update, and termination marker writes are Direct Writes. They are visible state changes but do not cascade. - -### B.6 Do not create checkpoints during initialization - -Checkpoint creation is lazy and external-channel-specific. - -### B.7 Do not skip must-understand - -Unsupported active contracts must be detected before mutation whenever they are in the initial active processing closure. - -### B.8 Do not use wall-clock or random behavior in contracts - -Determinism is part of conformance. - -### B.9 Do not treat lifecycle events as Triggered events - -Lifecycle events are delivered through Lifecycle Event Channels and recorded for bridging.

Root scope `/` plus `/contracts/x` must produce `/contracts/x`, not `//contracts/x`. - -### B.12 Do not pre-filter external channels for free - -Candidate external channels are charged before acceptance or rejection. Optimizations must preserve the same candidate set and gas. - -### B.13 Do not compare source bytes for reserved marker preservation - -Reserved processor marker preservation is Blue-node semantic equality after normalization, not YAML or JSON byte equality. - -### B.14 Do not let dispatch mutation rewrite the current call list - -Dispatch snapshots freeze which handlers/channels and executable contract content are called for the current delivery or Phase 3 candidate loop. Contract mutations affect later discovery points only. - -### B.15 Do not store escaped checkpoint keys - -`lastEvents` object members use raw contract-map keys. Escape `/` and `~` only when constructing a Blue Runtime Pointer for Direct Write. - -### B.16 Do not apply handler effects immediately - -Host APIs that look like `emitEvent`, `applyPatch`, or `terminate` buffer effect requests. Observable mutation, enqueueing, and termination happen only when the normalized result is applied. - -### B.17 Do not commit type-unsound patches - -After every patch, restore type soundness before delivering any Document Update cascade. If required generalization is rejected or has no valid target, the tentative patch is not committed. - -### B.18 Do not reuse Language view-path parsing for runtime pointers - -Blue Runtime Pointer `/` denotes the runtime root and is not a patch target.

Scope, Goals, Versioning, and Conformance - -### 1.1 Goal - -Blue is a universal, deterministic **content language** with: - -- a strict, mergeable type system with overlay and subtyping rules; -- a content address called **BlueId** that is stable across equivalent content forms; -- a precise pipeline that maps an authored document to deterministic content identity; -- graph-slice semantics, so documents can contain local content and external `blueId` references. - -### 1.2 Out of scope - -The following are not defined by this specification: - -- runtime execution; -- event processing; -- channels; -- handlers; -- gas accounting; -- document update listeners; -- processor lifecycle markers; -- contract execution. - -The field `contracts` is reserved by the language because it is a possible field in Blue content and therefore can affect BlueId. Its runtime meaning is defined only by the separate Blue Contracts and Processor Specification. - -### 1.3 Versioning - -This document defines **Blue Language 1.0**. - -A Blue node does not carry a required language-version field. A node's meaning is determined by this specification, its content, and the BlueIds of any referenced types. - -Implementations MUST declare which Blue Language version they implement. - -Blue Language 1.x revisions MUST preserve the meaning and BlueId of valid Blue Language 1.0 documents. Any incompatible change to the BlueId algorithm, node model, or resolution semantics requires a new major language version and an out-of-band version-selection mechanism. Such a mechanism MUST NOT require interpreting a node under the wrong BlueId algorithm before the version is known. - -### 1.4 Conformance - -A conforming Blue Language 1.0 implementation MUST implement all normative requirements in this specification. - -A conforming implementation MUST support: - -- parsing Blue Source Documents and BlueId Input; -- preprocessing, including the standard baseline preprocessing environment; -- type resolution and overlay merging; -- schema validation; -- list merge semantics and list control forms; -- provider-backed resolution when referenced content is required; -- expansion semantics, including provider-backed materialization when referenced content is required; -- collapse semantics if the implementation exposes a collapse API; -- canonicalization for Content BlueId calculation; -- author-facing minimization if the implementation exposes a minimization API; -- Node BlueId and Content BlueId calculation; -- circular reference set BlueIds; -- rejection of invalid Blue Language 1.0 documents and invalid BlueId Input; -- the Blue Language 1.0 conformance suite. - -Implementations MAY expose smaller internal APIs, such as direct Node BlueId calculation, but such APIs do not define separate conformance levels. - -A library or tool that implements only a subset of this specification may be useful, but it MUST NOT describe itself as a conforming Blue Language 1.0 implementation. - -### 1.5 Core registry dependency - -The canonical Blue type registry is part of the Blue Language 1.0 release surface. Its entries for `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` are content-addressed and versioned with this specification. - -A conforming implementation MUST use the registry BlueIds for core type aliases. A different registry binding does not produce portable Blue Language 1.0 Content BlueIds. - -Canonical registry nodes are self-describing Blue content. - -A registry node's `name` and `description` fields are identity-bearing content under the Blue Language. A canonical registry entry SHOULD include a concise normative `description` that defines the semantics of the type. Changing that semantic description changes the node's BlueId and therefore defines a different type. - -Non-normative examples, rationale, translations, tutorial material, implementation notes, and editorial commentary MUST NOT be included in canonical registry nodes unless intentionally made identity-bearing. Such material belongs in the prose specification, registry documentation, or examples outside the canonical node. - -The registry file is the authority for the exact byte/string content of canonical nodes. Code blocks in this specification that claim to show canonical nodes SHOULD be generated from, or kept byte-equivalent to, the registry entries used to calculate the published BlueIds. - -Practical editorial rule: if changing the text should change what the type means, put it in the canonical node. If changing the text only improves explanation, examples, formatting, translation, or teaching, keep it outside the canonical node. - -The canonical registry entry for each core type MUST include: - -- the exact canonical Blue node; -- the node's calculated BlueId; -- the Blue Language version that publishes it; -- the conformance fixture package identity that verifies it. - -A conforming implementation MUST verify, at release or test time, that every bundled core type node hashes to the published registry BlueId. - -The Blue Language 1.0 release is defined by three artifacts together: - -1. this prose specification; -2. the canonical Blue type registry for Blue Language 1.0; -3. the Blue Language 1.0 conformance fixture package. - -If these artifacts conflict, the release is inconsistent and MUST be corrected. Implementations MUST NOT guess which artifact wins. - -The prose explains the rules, the registry supplies the exact identity-bearing type nodes and BlueIds, and the fixtures provide behavior-defining examples. These artifacts MUST be versioned and published together. - -The fixture package is behavior-defining. It MUST publish exact expected BlueIds, canonical registry BlueIds, and fixture package identity. - ---- - -## 2. Serialization and Data Model - -### 2.1 JSON data model (normative) - -Blue documents use the JSON data model: - -- objects; -- arrays; -- strings; -- numbers; -- booleans; -- null. - -YAML is an authoring syntax for this JSON data model. A YAML parser used for Blue MUST NOT introduce YAML-specific data types into the Blue data model. - -### 2.2 YAML restrictions (normative) - -When YAML is used for Blue serialization: - -- duplicate object keys MUST be rejected; -- custom YAML tags MUST be rejected; -- Portable Blue YAML MUST reject YAML anchors, aliases, and merge keys. An implementation MAY expose a non-portable preprocessing mode that expands them deterministically before Blue parsing, but documents relying on that mode are not portable Blue Source Documents. -- non-JSON implicit types, including timestamps, binary blobs, sets, and ordered maps, MUST be disabled; -- timestamp-like values SHOULD be quoted by authors. Blue Language 1.0 defines no timestamp scalar. - -Blue YAML 1.0 uses the YAML 1.2 JSON schema data model. Portable Blue YAML MUST reject custom tags, non-string object keys, binary tags, sets, ordered maps, and non-JSON implicit scalar types. - -The parsed value of a YAML block scalar is the exact Text value. Blue performs no block-scalar normalization. Different YAML scalar styles, indentation, folding, chomping indicators, trailing newlines, or line endings that produce different parsed strings produce different BlueIds. - -Examples: - -```yaml -# Text, not a Date/Time type in Blue Language 1.0 -ts: "2025-09-01T12:00:00Z" -``` - -Blue Language 1.0 does not define a core Date or Timestamp scalar type. - -### 2.3 Duplicate keys (normative) - -Serialized Blue documents MUST NOT contain duplicate object keys. Parsers MUST reject duplicate keys. Later-key-wins behavior is not conforming. - -### 2.4 Number tokens and large integers (normative) - -Blue distinguishes the mathematical value of an integer from the JSON/YAML encoding used to carry it. - -The interoperable **safe JSON numeric integer range** for Blue Language 1.0 is: - -```text -[-9007199254740991, 9007199254740991] -``` - -JSON itself does not define a numeric range. Blue uses this safe range because it is exactly representable by JSON implementations that store numbers as IEEE 754 binary64 values. - -Rules: - -1. An unquoted integer token within this range MAY be used as an `Integer` value. -2. An integer value outside this range MUST be authored as a quoted canonical decimal string and MUST have explicit type `Integer` or a type that resolves to `Integer`. -3. In Canonical Identity Input and BlueId Input, an `Integer` value outside this range MUST be represented as its quoted canonical decimal string while retaining the explicit `Integer` type. -4. The canonical decimal string form is an optional leading `-` followed by decimal digits, with no leading zeros except the single digit `0`. -5. Quoted decimal text without an explicit `Integer` type is Text, not Integer. - -A quoted canonical decimal string value is interpreted as an `Integer` when the node has an explicit effective type that resolves to `Integer`. The effective type may be authored locally or inherited from the resolved type chain. - -If no effective type resolves to `Integer`, quoted decimal text is Text. - -If an effective type resolves to `Integer` and the quoted value is not a valid canonical decimal integer string, resolution MUST fail. - -Primitive scalar inference for quoted strings is provisional for Source Documents. Resolution MAY refine a quoted scalar's effective scalar type when an inherited or explicit type requires `Integer` and the quoted value is a valid canonical decimal integer string. - -Examples: - -```yaml -small: - type: Integer - value: 42 - -large: - type: Integer - value: "9007199254740992" -``` - -The same rule applies below the negative bound: - -```yaml -veryNegative: - type: Integer - value: "-9007199254740992" -``` - -Example with inherited Integer type: - -```yaml -# Type -name: Account -accountId: - type: Integer - -# Source instance -type: Account -accountId: "9007199254740992" -``` - -After preprocessing and resolution, `accountId` is an Integer value because the effective inherited type resolves to `Integer`. - -Without the inherited or explicit Integer type, the same quoted value is Text. - -Floating-point `Double` values MUST be finite. `NaN`, `Infinity`, and `-Infinity` are not valid Blue scalar values. - -Double parsing MUST produce a finite IEEE 754 binary64 value using round-to-nearest, ties-to-even semantics. A numeric token that overflows to positive or negative Infinity, underflows to a non-finite value, or parses as NaN is invalid. - -A parsed `-0.0` Double value compares equal to `0.0` and canonicalizes as JSON number `0` under RFC 8785. The node remains Double because its effective type is Double. - -A Double whose RFC 8785 canonical JSON representation is integer-looking, such as `1`, remains Double because its effective type is represented in BlueId Input. - -If a parser cannot deterministically parse a numeric token as binary64 with these semantics, the implementation MUST reject the token or require explicit authoring in a supported form. - -### 2.5 Numeric token inference (normative) - -When a numeric Source Document value has no explicit type: - -- an unquoted integer token with no decimal point and no exponent infers `Integer`; -- an unquoted numeric token with a decimal point or exponent infers `Double`, even if its mathematical value is integral. - -Examples: - -```yaml -a: 1 # Integer -b: 1.0 # Double, canonical numeric payload may render as 1 -c: -0.0 # Double, canonical numeric payload renders as 0 -d: 1e999 # invalid Double -``` - -If a parser cannot preserve the lexical distinction between integer tokens and decimal/exponent tokens, it MUST require explicit type annotations for ambiguous numeric values or document that such inputs are not portable Source Documents. - -### 2.6 String and multiline scalar identity (normative) - -After parsing, a Blue string value is identity-bearing exactly as parsed. Blue Language performs no automatic whitespace normalization, line-ending normalization, trailing newline stripping, indentation rewriting, Unicode normalization, case folding, or YAML block-scalar canonicalization. - -Different YAML scalar styles may produce different string values and therefore different BlueIds. In particular, YAML block scalar choices such as `|`, `|-`, `|+`, `>`, and `>-` may differ in line folding and trailing newline behavior. - -Canonical registry nodes SHOULD be generated, fixture-checked, or otherwise protected against accidental string drift. Authors of identity-sensitive documents SHOULD treat edits to multiline `description` fields as content edits, not formatting edits. - -Blue Language uses the parsed Unicode code-point sequence. Implementations MUST NOT normalize Text by default. Applications that need a normalization convention, such as NFC, SHOULD apply it explicitly at the application/preprocessing layer. - ---- - -## 3. Blue Graph, Blue Documents, and References - -### 3.1 The Blue Graph (normative) - -The **Blue Graph** is the conceptual content-addressed network of Blue nodes. Edges in the graph arise from: - -- ordinary object fields, for example `address -> child node`; -- list elements; -- type links, for example `type: ...`; -- `blueId` references. - -Nodes are identified by BlueId. The graph is global and content-addressed; it is not owned by any single document. - -### 3.2 Blue Documents as graph slices (normative) - -A **Blue Document** is a serialized rooted slice of the Blue Graph. It may contain: - -- fully materialized child nodes; -- pure references to external nodes using `{ blueId: ... }`; -- a mixture of local content and external references. - -A Blue Document is not required to be closed. A `{ blueId: X }` reference may point to content outside the selected document. Implementations may require a provider to expand references, resolve types, or canonicalize a view. - -### 3.3 Pure references (normative) - -A **pure reference** is exactly: - -```yaml -blueId: -``` - -or, as a field value: - -```yaml -field: - blueId: -``` - -A pure reference object MUST NOT carry sibling fields. The following is not a pure reference: - -```yaml -blueId: -name: Something -foo: bar -``` - -Mixed `blueId` forms MUST be rejected in Source Documents, Preprocessed Documents, Canonical Identity Input, and BlueId Input. Provider metadata MUST be represented out-of-band or in a non-Blue envelope. - -A non-Blue envelope is packaging metadata outside the Blue Document root. It is not part of the Blue node and is not included in BlueId calculation. - -A pure reference cannot carry sibling fields. To refine or extend referenced content, the reference MUST appear in a type position or be resolved as an ancestor/type, and the overlay MUST be written as ordinary instance content outside the pure reference object. - -Invalid: - -```yaml -blueId: X -extra: value -``` - -Valid as a typed overlay: - -```yaml -type: - blueId: X -extra: value -``` - -### 3.4 Document identity (normative) - -The BlueId of a Blue Document is the BlueId of its root node. There is no separate document-level identity above the root node. - -A Blue Document root MAY be a scalar, list, object, or pure reference. Scalar and list roots follow the same wrapper-equivalence rules as field values. A Blue Document root MUST NOT be `null`. - ---- - -## 4. Node Model and Reserved Fields - -### 4.1 Node anatomy (normative) - -A **Blue node** consists of reserved language fields and, optionally, one primary payload kind. - -```text -Node = reserved language fields + zero or one payload kind -``` - -The permitted payload kinds are: - -- **scalar payload**: a `value` field carrying a string, number, or boolean; -- **list payload**: an `items` field carrying an ordered sequence; -- **object payload**: one or more ordinary child fields, where ordinary child fields are fields whose keys are not reserved language keys. - -A node MUST NOT combine payload kinds. For example, a node MUST NOT contain both `value` and `items`, or both `value` and ordinary child fields. - -A node MAY have no payload. Such a node is a metadata-only, type-only, schema-only, or overlay-only node. Examples include: - -```yaml -age: - type: Integer -``` - -and: - -```yaml -name: Person -``` - -A pure reference is a special metadata-only reference node. It is valid only when the object contains exactly `blueId`. - -If a node has no payload and no retained reserved content after object-field cleaning, it may normalize to an empty map and be omitted when it appears as an object field. It MUST NOT be silently deleted when it appears as a list element; list element normalization is context-sensitive (§11.5, §14.2). - -### 4.2 Reserved language keys (normative) - -The following keys are reserved by the language: - -```text -name, description, -type, itemType, keyType, valueType, -value, items, -blueId, blue, -schema, mergePolicy, -contracts -``` - -The following keys are reserved-invalid and MUST be rejected wherever they would appear as object fields: - -```text -properties, constraints -``` - -Reserved fields are grouped as follows: - -| Category | Fields | -|---|---| -| Identity labels | `name`, `description` | -| Type and constraint metadata | `type`, `itemType`, `keyType`, `valueType`, `schema`, `mergePolicy` | -| Payload wrappers | `value`, `items` | -| Reference and preprocessing controls | `blueId`, `blue` | -| Reserved extension field | `contracts` | - -`contracts` is reserved by the language but semantically defined only by the Blue Contracts and Processor Specification. - -The key `blue` is valid only as a preprocessing directive on the root of a Source Document. A conforming implementation MUST reject `blue` anywhere else. Direct Node BlueId calculation MUST reject any node containing `blue` as direct BlueId Input. - -There is no `properties` field in the Blue Language. The key `properties` is reserved-invalid in Blue Language 1.0 and MUST NOT appear as an ordinary child field or language wrapper. Applications that need a data key literally named `properties` MUST use an escaped representation defined by the application's type. - -Reserved language keys cannot be used as ordinary child-field names in direct object encoding. Direct object encoding can therefore represent only data keys that do not collide with reserved language keys. -Applications that need arbitrary user keys, including keys that equal reserved language keys, MUST use an escaped representation defined by the application's type. - -### 4.3 Reserved field value types (normative) - -Implementations MUST validate reserved field value types. - -| Field | Required value shape | -|---|---| -| `name` | string, or absent | -| `description` | string, or absent | -| `type` | node, string alias in Source Documents before preprocessing, or pure reference | -| `itemType` | node, string alias in Source Documents before preprocessing, or pure reference | -| `keyType` | node, string alias in Source Documents before preprocessing, or pure reference | -| `valueType` | node, string alias in Source Documents before preprocessing, or pure reference | -| `value` | string, number, boolean, or absent | -| `items` | list, or absent | -| `blueId` | string BlueId, only in pure references | -| `blue` | string or object directive; root Source Document only | -| `schema` | object using only schema keywords from §9 | -| `mergePolicy` | `append-only`, `positional`, or absent | -| `contracts` | object; runtime semantics out of scope | - -Wrong reserved-field types MUST be rejected. Implementations MUST NOT silently coerce reserved field values such as `blueId: 123` or `name: true` into strings. - -### 4.4 `contracts` boundary (normative) - -In Blue Language 1.0, `contracts` is a reserved identity-bearing content field. A language implementation MUST parse, preserve, resolve, canonicalize, and hash `contracts` as content. It MUST NOT execute `contracts`. - -Unless a separate processor specification is explicitly being applied, `contracts` participates in language-level merge and canonicalization according to ordinary object-field rules. Runtime interpretation, reserved processor keys under `contracts`, processor lifecycle behavior, and contract capability handling are outside this specification. - -Language-level merge of `contracts` is field-wise: - -- If only the ancestor contributes a contract entry at key `k`, the entry is materialized in the Resolved View as type-derived content. -- If only the instance contributes a contract entry at key `k`, the entry is preserved as instance-supplied content. -- If both ancestor and instance contribute `contracts[k]`, the two contract nodes are merged recursively under the same fixed-value, type-compatibility, schema, and object-field rules used for ordinary child fields. -- A descendant MUST NOT remove an inherited contract entry during language resolution. Runtime removal or mutation of contracts, if allowed, belongs to the Blue Contracts and Processor Specification. -- The language resolver MUST NOT interpret, execute, sort, dispatch, or validate processor-specific contract behavior. - -Processor-reserved keys inside `contracts` have no runtime effect in this specification. They are still parsed, resolved, canonicalized, and hashed as content. - -### 4.5 `name` and `description`: identity vs field semantics (normative) - -`name` and `description` are content on the node. They affect BlueId. - -They are also matcher-neutral. Matchers MUST ignore `name` and `description` for: - -- type conformance checks; -- subtype compatibility checks; -- structural or shape matching; -- resolution matching. - -Identity equality includes `name` and `description`. Structural and type equality ignore them. - -### 4.6 Document identity vs field semantics for labels (normative) - -A node whose `type` is `T` is not `T`; it is a new entity. The resolved node's top-level `name` and `description` come only from the instance and MUST NOT be inherited from the type. The embedded type object may carry its own `name` and `description` inside `node.type`. - -When a type materializes declaration-only fields or list elements into an instance, those child nodes carry the type's `name` and `description` as inherited labels until the instance explicitly overrides them. - -However, when the inherited child node contains a fixed payload value, fixed list payload, fixed object subtree, or pure reference, the labels on that node are part of the inherited fixed value's identity. A descendant MUST NOT change `name` or `description` on such a fixed-value node unless the inherited type leaves that label absent or the change is otherwise allowed by an explicit resolution rule. - -Dereferencing `{ blueId: X }` to materialize a node may copy the referenced node's `name` and `description` onto that materialized node, because the node itself is being materialized. This is expansion, not type inheritance. - ---- - -## 5. Authoring Forms and Wrapper Equivalence - -### 5.1 Wrapper equivalence (normative) - -To improve ergonomics, Blue admits equivalent authoring forms for scalars and lists, provided the wrapper has no other keys. - -Scalar sugar: - -```yaml -x: 1 -``` - -is equivalent to the wrapped form: - -```yaml -x: - value: 1 -``` - -List sugar: - -```yaml -x: [a, b] -``` - -is equivalent to: - -```yaml -x: - items: [a, b] -``` - -### 5.2 Sugar vs explicit metadata (normative) - -The sugar rule applies only when the wrapper has no other keys. Therefore: - -```yaml -x: 1 -``` - -is sugar for: - -```yaml -x: - value: 1 -``` - -but: - -```yaml -x: - type: Integer - value: 1 -``` - -is not sugar. It is the explicit scalar node form with metadata. - -A node may carry metadata such as `type`, `description`, `schema`, or `mergePolicy` alongside a payload kind. Metadata is not a payload kind. - -### 5.3 Object nodes (normative) - -Object payloads are written directly as ordinary child fields: - -```yaml -x: - a: 1 - b: 2 -``` - -There is no `properties` wrapper. The key `properties` is reserved-invalid (§4.2). - -### 5.4 Identity over forms (normative) - -Equivalent authoring forms of the same semantic content MUST produce the same Content BlueId. - -The BlueId algorithm operates on the abstract node model after canonical input normalization, not on authoring syntax. In particular, a bare scalar and its `{ value: ... }` wrapped form normalize identically. A bare list and its `{ items: ... }` wrapped form normalize identically. - ---- - -## 6. Preprocessing and the `blue` Directive - -### 6.1 Purpose (normative) - -The root of a Source Document MAY contain a `blue` field. The `blue` directive declares preprocessing transforms that normalize authoring conveniences before the document is treated as identity-bearing content. - -A string-valued `blue` directive identifies a preprocessing environment or import document according to the implementation's declared preprocessing configuration. -An object-valued `blue` directive declares imports and preprocessing transforms directly. The exact object fields supported by a preprocessing environment MUST be deterministic and documented by that environment. - -Preprocessing is part of Content BlueId calculation. It is not part of direct Node BlueId calculation, because direct Node BlueId accepts only BlueId Input. - -A conforming implementation MUST support this portable `blue.imports` shape: - -```yaml -blue: - imports: - AliasName: - blueId: -``` - -Each key under `imports` is an authoring alias. Each value MUST be a pure reference object. During preprocessing, occurrences of that alias in `type`, `itemType`, `keyType`, or `valueType` positions are replaced by the corresponding pure reference. - -Aliases declared in `blue.imports` are scoped to the Source Document being preprocessed. They are removed with the `blue` directive and are not identity content after preprocessing. - -An alias name MUST NOT be declared more than once in the same `imports` object. An alias declared in `blue.imports` MUST NOT redefine a built-in core type name unless it maps to the same canonical BlueId. - -### 6.2 Standard baseline preprocessing (normative) - -A conforming implementation MUST support the standard baseline preprocessing environment: - -1. **Core type aliases to BlueIds.** Core aliases such as `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` are replaced by canonical type references supplied by the canonical Blue type registry. -2. **Document-declared aliases to BlueIds.** Aliases other than the built-in core type names MUST be declared by the Source Document, for example through the root `blue` directive, or by content-addressed import documents referenced from it. -3. **Primitive scalar inference.** Bare scalar payloads with no explicit type are assigned the corresponding core primitive type: `Text`, `Integer`, `Double`, or `Boolean`. -4. **Wrapper normalization.** Scalar and list sugar are normalized into the abstract node model. -5. **List placeholder normalization.** In Source Documents, list elements that are `null`, `{}`, or that recursively normalize to an empty object after object-field cleaning are normalized to `$empty: true` (§11.5). - -If the root `blue` directive is omitted, conforming implementations MUST still apply the standard baseline preprocessing environment. If a `blue` directive is present, it MAY configure imports and additional declared supported transforms, but it MUST NOT disable the mandatory baseline transforms required for interoperability. - -Implementation-local alias configuration MAY be used for authoring convenience, but documents depending on undeclared implementation-local aliases do not have portable Content BlueIds. - -### 6.3 Additional preprocessing transforms (normative) - -Additional preprocessing transforms MAY be used only when they are explicitly declared by the root `blue` directive and supported by the implementation. -Such transforms MUST be deterministic. If a Source Document requires a transform that the implementation does not support, preprocessing MUST fail. -Any imported preprocessing document that affects Content BlueId MUST itself be identified by BlueId or by a deterministic registry binding declared by the Source Document. -A document that depends on implementation-local transforms not declared by the Source Document does not have a portable Content BlueId. - -### 6.4 Preprocessing rules (normative) - -- The `blue` directive is valid only on the root of a Source Document. -- The `blue` directive is not semantic content. -- A document containing `blue` is not valid BlueId Input. -- Preprocessing MUST remove the `blue` directive after applying it. -- Direct Node BlueId calculation MUST reject a node containing `blue`. -- Content BlueId calculation MUST preprocess the document and remove `blue` before hashing. - -Simply ignoring `blue` is not correct. The directive may define aliases and transforms that change the canonical content. A direct hasher that sees `blue` MUST reject the input rather than hash a partially processed structure. - -### 6.5 Security (normative) - -Remote fetch of preprocessing imports or transforms is DISABLED by default. Implementations MAY support remote preprocessing documents only through explicit opt-in configuration and deterministic caching rules. - -Any preprocessing import document or transform document fetched by BlueId MUST be verified against that BlueId before use. If verification fails, preprocessing MUST fail deterministically. - -A preprocessing import that is not identified by BlueId MUST be supplied by a deterministic registry binding declared by the Source Document or by the implementation's declared preprocessing configuration. Such bindings are outside the portable Source Document unless their identity is included in the conformance fixture or release artifact. - ---- - -## 7. BlueId and Content Identity - -### 7.1 BlueId summary (normative) - -Every Blue node has a content identity called its **BlueId**. The BlueId of a Blue Document is the BlueId of its root node. - -BlueId is a content address: equivalent representations of the same content produce the same identity after the relevant view transformations have been applied. - -This section defines BlueId conceptually. The algorithmic details are in §14. - -### 7.2 Node BlueId and Content BlueId (normative) - -Blue defines two related identities. - -**Node BlueId** is the result of applying the BlueId algorithm directly to valid **BlueId Input**. - -**Content BlueId** is the semantic identity of a Source Document. It is calculated as: - -1. preprocess the Source Document (§6); -2. resolve type chains and validate constraints (§10), producing a Resolved View; -3. canonicalize the Resolved View into a Canonical Identity Input (§13); -4. compute the Node BlueId of the Canonical Identity Input (§14). - -All conforming implementations MUST produce the same Content BlueId for equivalent Source Documents, given the same provider state required for resolution. - -### 7.3 Identity preservation across views (normative) - -Expansion preserves Node BlueId when the provider returns verified content. Pure references hash to their target BlueId; materializing a reference into content does not change the surrounding node's Node BlueId if the materialized content has that BlueId. - -Collapse preserves Node BlueId. Replacing materialized content with a pure reference to its known BlueId yields the same Node BlueId. - -Resolution preserves semantic identity. A Source Document and its Resolved View have the same Content BlueId when the Resolved View is canonicalized. - -A Resolved View is not generally direct BlueId Input. It may contain inherited or materialized fields that are derivable from the type chain. Directly hashing a Resolved View is not guaranteed to produce the Content BlueId. - -### 7.4 BlueId Input (normative) - -**BlueId Input** is any node valid for direct application of the BlueId algorithm after BlueId input normalization. - -BlueId Input MUST NOT contain: - -- the `blue` directive; -- unresolved aliases introduced only for authoring convenience; -- illegal payload combinations; -- invalid list-control forms; -- mixed `blueId` reference shapes; -- unresolved cyclic placeholders such as `this#0`, except inside the explicit cyclic-set calculation API defined in §15; -- `$pos` overlays; -- `null` list elements; -- empty-object list elements that have not been normalized to `$empty: true`. - -A node containing `blue` MUST NOT be accepted as direct BlueId Input. The `blue` directive is never identity content. - -### 7.5 Allowed BlueId forms (normative) - -A **plain BlueId** is the Base58 encoding of a SHA-256 digest using the following alphabet: - -```text -123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz -``` - -Blue Language 1.0 does not define alternative BlueId alphabets. A registry MAY define aliases or packaging metadata, but MUST NOT redefine the BlueId hash alphabet. - -A plain BlueId MUST be the canonical Base58 encoding of exactly 32 bytes, the output length of SHA-256. Implementations MUST reject non-canonical Base58 encodings, strings containing characters outside the BlueId alphabet, and strings that decode to any length other than 32 bytes. - -A plain BlueId MUST NOT contain `#`. The `#` suffix syntax is reserved for cyclic-set member BlueIds. - -The ZERO_BLUEID sentinel defined in §15.2 is not a plain BlueId because the character `0` is not in the BlueId alphabet. - -A **cyclic-set member BlueId** has the form: - -```text -# -``` - -where `MASTER` is the plain BlueId of the ordered cyclic set list and `index` is a non-negative decimal integer. - -`this#` is an algorithm-internal placeholder accepted only by the explicit cyclic-set calculation API defined in §15. It MUST NOT appear in ordinary BlueId Input or provider-stored content. - ---- - -## 8. Types, Overlays, and Subtyping - -### 8.1 Any node can be a type (normative) - -There is no schema-versus-instance bifurcation in Blue. Any node can appear under `type`. - -If `T` is used in `type: T`, then `T` contributes: - -- structure; -- nested type chains; -- schema constraints; -- fixed values. - -A type is an **overlay source**, not a class declaration. - -### 8.2 Fixed-value invariant (normative) - -A concrete value embedded in a type is immutable in descendants at that path. A descendant MUST NOT replace, remove, or contradict that value. Any attempted override MUST fail resolution. - -For example, if a type fixes: - -```yaml -country: - value: PL -``` - -then a descendant cannot resolve with: - -```yaml -country: - value: US -``` - -### 8.3 Fixed-value equality (normative) - -Fixed-value equality is evaluated after preprocessing and wrapper normalization. - -- Scalar equality compares the parsed scalar value and effective scalar type. -- Object and list equality compares the Node BlueId of the normalized subtree. -- `name` and `description` are content for fixed-value equality. Matcher neutrality applies to type/shape matching, not to identity equality of fixed values. - -Scalar payload equality compares parsed scalar value and effective scalar type. Full fixed-node equality compares the normalized Blue node identity, including `name`, `description`, metadata, and payload. Thus a descendant may not change labels on an inherited fixed-value node, because doing so changes the fixed node's identity. - -Therefore these are equal after wrapper normalization: - -```yaml -city: Warsaw -``` - -```yaml -city: - value: Warsaw -``` - -but these are different fixed values because labels are identity content: - -```yaml -city: - name: City - value: Warsaw -``` - -```yaml -city: - name: Location - value: Warsaw -``` - -Valid label override on declaration-only field: - -```yaml -# Parent type -city: - name: City - type: Text - -# Descendant -city: - name: Location - value: Warsaw -``` - -Invalid label override on fixed-value field: - -```yaml -# Parent type -city: - name: City - value: Warsaw - -# Descendant -city: - name: Location - value: Warsaw -``` - -The second case fails because the inherited fixed node includes the label `name: City` as identity content. - -### 8.4 Subtyping and Liskov substitutability (normative) - -When resolving, descendants MUST satisfy: - -1. **No fixed-value override.** Immutable values inherited from types cannot be changed. -2. **Type compatibility.** A descendant type at a path must be equal to or a subtype of the inherited type at that path (§8.4.1). -3. **Additive structure.** Guaranteed fields cannot be deleted. -4. **Collection compatibility.** `itemType`, `keyType`, and `valueType` compatibility must be preserved. - -Every instance of a subtype MUST be substitutable for its parent. - -If `itemType`, `keyType`, or `valueType` is inherited at a path, a descendant that omits the field inherits it. A descendant MAY narrow the inherited type by supplying an equal type or subtype. A descendant MUST NOT widen, remove, or replace the inherited type with an incompatible type. - -Omitting `itemType`, `keyType`, or `valueType` means unconstrained only when there is no inherited effective type constraint at that path. - -### 8.4.1 Formal subtype relation (normative) - -For Blue Language 1.0, `T <: P` ("T is a subtype of P") iff resolving `T` as a descendant overlay of `P` succeeds under the resolution rules in §10, and every valid instance of `T` is substitutable where an instance of `P` is required. - -A subtype check MUST ignore `name` and `description` for matcher/type-shape purposes, but fixed-value equality still includes `name` and `description` because they are identity content (§8.3). - -For each path contributed by parent type `P`, subtype `T` MUST satisfy all of the following: - -1. **Fixed values preserved.** If `P` fixes a scalar, object, list, or subtree value at a path, `T` MUST preserve the same fixed value under §8.3. -2. **Guaranteed structure preserved.** If `P` guarantees a field or list prefix element, `T` MUST keep it present in all valid instances unless a specific list merge rule explicitly refines it without removal. -3. **Schema constraints compatible.** Every schema constraint contributed by `P` MUST remain satisfied by `T`. Additional constraints in `T` are allowed only when their intersection with inherited constraints is non-empty and not weaker. -4. **Type constraints narrowed only.** If `P` declares `type`, `itemType`, `keyType`, or `valueType` at a path, `T` may repeat the same type or provide a subtype. It MUST NOT omit, widen, or replace the inherited effective type constraint with an incompatible type. -5. **Payload kind compatible.** Scalar, list, and object payload kinds MUST remain compatible with inherited guarantees. A subtype MUST NOT turn an inherited scalar requirement into a list/object requirement, or vice versa, unless resolution can prove the inherited requirement is not applicable. -6. **List policies preserved.** An inherited `mergePolicy: append-only` MUST remain append-only. A descendant MUST NOT weaken append-only to positional. If no merge policy is inherited and none is authored, the effective default is positional. - -Equivalently, `T <: P` when the Resolved View produced by resolving `T` over `P` is valid and does not violate any invariant or guarantee of `P`. - -If checking `T <: P` requires resolving a type chain that revisits a type already on the active resolution stack, resolution MUST fail with a type-cycle error (§10.2.1). - -### 8.4.2 Nominal core type identity (normative) - -The canonical core primitive and collection types `Text`, `Integer`, `Double`, `Boolean`, `Dictionary`, and `List` are **nominal** Blue Language types identified by their canonical registry BlueIds. - -A type resolving to one of these canonical core types is compatible with another such type only when the canonical registry BlueId is equal, unless the canonical registry explicitly declares a subtype relationship. Blue Language 1.0 declares no implicit subtype relationship between distinct core types. - -Matcher-neutral treatment of `name` and `description` applies to structural field matching and subtype shape checks. It does **not** make two different canonical registry type identities interchangeable. If a core type description changes and therefore the type BlueId changes, it is a different nominal type. - -Examples: - -- The canonical `Integer` type is compatible with itself by registry BlueId. -- A node named `Integer` with a different description and different BlueId is not the canonical `Integer` type. -- `Integer` and `Double` are not subtypes of each other in Blue Language 1.0. - -### 8.5 Instance-as-type (normative) - -Nodes representing individuals can be used as types. - -For example: - -- `Alice` may have `type: Person`. -- `Alice Smith` may have `type: Alice`. - -All fixed values in `Alice` become invariants in `Alice Smith`. Alice's top-level `name` and `description` do not flow to Alice Smith (§4.6). - -### 8.6 Requirement overlays (normative) - -An ancestor may partially constrain a subtree without binding a concrete type at that path. - -Example: - -```yaml -# Parent -name: A -prop1: - x: 1 - schema: - minFields: 1 -``` - -A descendant may later set: - -```yaml -name: B -type: A -prop1: - type: Some -``` - -This is valid only if the merged result still satisfies all overlay obligations, including fixed values and schema constraints. If the overlay had a type, the descendant's type must be equal to or a subtype of that type. - -If the overlay forces `x = 1` but `Some` forces `x = 2`, resolution MUST fail. - ---- - -## 9. Schema Constraints - -### 9.1 Attaching schema (normative) - -A `schema` object MAY be attached to any node. - -All schema constraints accumulate along the type chain. Compatible constraints are intersected according to §9.9. Irreconcilable constraints MUST fail resolution. - -### 9.2 Schema vocabulary (normative) - -Only the keywords listed in §9.3-§9.8 are valid inside a `schema` object. Implementations MUST reject any other key inside `schema`. - -The valid schema keywords are: - -```text -required, -minItems, maxItems, uniqueItems, -minFields, maxFields, -minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, -minLength, maxLength, -enum -``` - -A schema object MUST NOT contain any key outside this list. - -### 9.2.1 Schema keyword value types (normative) - -| Keyword | Required value shape | -|---|---| -| `required` | boolean | -| `minItems`, `maxItems`, `minFields`, `maxFields`, `minLength`, `maxLength` | non-negative integer in the safe JSON numeric integer range | -| `uniqueItems` | boolean | -| `minimum`, `maximum`, `exclusiveMinimum`, `exclusiveMaximum`, `multipleOf` | numeric scalar or explicit numeric scalar node | -| `enum` | list of scalar values or explicit scalar nodes | - -A schema keyword value with the wrong shape MUST be rejected. Implementations MUST NOT coerce schema keyword values across scalar types. - -### 9.2.2 Schema applicability (normative) - -Each schema keyword applies only to the effective node kind for which it is defined. - -- String constraints apply only to effective Text values. -- Numeric constraints apply only to effective Integer or Double values. -- List constraints apply only to effective list payloads. -- Object field-count constraints apply only to effective object payloads. -- `enum` applies to scalar values unless an explicit scalar-node enum entry is used. -- `required` applies to the child field declaration at the path where it appears. - -If a schema keyword is evaluated against an incompatible effective node kind, validation MUST fail with a schema violation. Implementations MUST NOT silently ignore incompatible schema keywords. - -### 9.2.3 Required fields (normative) - -`required: true` on a child field declaration requires that the field be semantically present in resolved descendants. - -A required field is satisfied only if the resolved child node contains at least one of: - -- a scalar payload `value`; -- a list payload `items`, including an empty list; -- an object payload with at least one ordinary child field; -- a pure reference; -- a fixed payload or fixed subtree inherited from an ancestor type. - -A metadata-only child declaration, such as a node containing only `type`, `schema`, `name`, or `description`, does not by itself satisfy `required: true`. - -If a field is required but has no semantic payload or fixed inherited content after resolution and cleaning, validation MUST fail. - -### 9.2.4 Field counting (normative) - -`minFields` and `maxFields` count ordinary child fields of the effective object payload after resolution and object-field cleaning. - -Reserved language fields such as `name`, `description`, `type`, `schema`, `contracts`, `value`, and `items` do not count as ordinary fields. - -Fields removed by object-field cleaning do not count. Inherited ordinary child fields that are materialized in the Resolved View do count. - -### 9.3 Presence - -```yaml -required: true -``` - -When a schema with `required: true` is attached to a child field in a type or object overlay, that field MUST be semantically present in resolved descendants according to §9.2.3. If used at a document root, `required` is trivially satisfied by the existence of the root node. - -### 9.4 Lists - -```yaml -minItems: -maxItems: -uniqueItems: true | false -``` - -`maxItems` MUST be greater than or equal to `minItems` when both are present. - -`uniqueItems: true` compares items by item BlueId, not by textual rendering. - -### 9.5 Objects - -```yaml -minFields: -maxFields: -``` - -`maxFields` MUST be greater than or equal to `minFields` when both are present. - -The term **fields** is used because Blue objects have direct ordinary fields and no `properties` wrapper. - -### 9.5.1 Dictionary direct encoding validation (normative) - -For direct Dictionary object encoding, each direct key MUST be valid under the effective `keyType`. - -For direct object encoding, `keyType` MUST resolve to one of the scalar key types with a canonical textual representation: Text, Integer, Double, or Boolean. If `keyType` is omitted and no effective `keyType` is inherited, it defaults to Text. - -A key's serialized object-member name MUST be exactly the canonical textual form of the parsed key value. If two key values canonicalize to the same object-member string, the document has a duplicate key conflict and MUST be rejected. - -Every value in a Dictionary with an effective `valueType` MUST resolve as an instance of, or subtype-compatible with, the effective `valueType`. - -Applications needing arbitrary non-scalar keys or reserved-key collisions MUST use an application-defined escaped representation rather than direct object encoding. - -### 9.6 Numerics - -```yaml -minimum: number -maximum: number -exclusiveMinimum: number -exclusiveMaximum: number -multipleOf: number -``` - -Numeric schema keyword values MAY be authored in either scalar form or explicit scalar-node form. - -Scalar form: - -```yaml -schema: - minimum: 5 -``` - -Explicit scalar-node form: - -```yaml -schema: - minimum: - type: Integer - value: "9007199254740992" -``` - -A quoted decimal string without explicit `type: Integer` is Text and MUST NOT be accepted as a numeric constraint. - -Rules: - -- `minimum: m` means the numeric value must be greater than or equal to `m`. -- `maximum: m` means the numeric value must be less than or equal to `m`. -- `exclusiveMinimum: m` means the numeric value must be strictly greater than `m`. -- `exclusiveMaximum: m` means the numeric value must be strictly less than `m`. -- `multipleOf` must be greater than zero. - -If multiple numeric constraints appear in the type chain, the value must satisfy all of them. For integer `multipleOf` constraints, implementations MUST combine compatible constraints using least common multiple (LCM). The effective merged schema MUST contain one `multipleOf` value equal to that LCM, and the Resolved View and Canonical Identity Input MUST NOT preserve an implementation-specific list of equivalent integer `multipleOf` constraints. - -For `Double` `multipleOf`, both the tested value and the `multipleOf` constraint are interpreted as their exact IEEE 754 binary64 rational values after parsing. A Double value `v` satisfies `multipleOf: m` iff `m > 0` and the exact rational quotient `v / m` is an integer. Implementations MUST NOT use epsilon comparisons, decimal string rounding, host-language modulo on binary floating point, or implementation-specific approximation. - -For cross-type numeric comparisons, an `Integer` value is interpreted as an exact rational integer. A `Double` bound or value is interpreted as its exact IEEE 754 binary64 rational value. Comparison between Integer and Double uses exact rational comparison. - -A numeric token that cannot be parsed to a finite IEEE 754 binary64 value under §2.4 is invalid before schema evaluation. - -Implementations MAY use arbitrary-precision rational arithmetic internally to implement these predicates. They MUST NOT expose host floating-point rounding differences in conformance behavior. - -Numeric schema keyword values follow the same numeric representation rules as scalar values (§2.4). Integer constraints outside the safe JSON numeric integer range MUST be represented as typed Integer scalar nodes that preserve exact integer identity. Quoted decimal text without explicit Integer typing is Text and MUST NOT be treated as a numeric schema constraint. - -### 9.7 Strings - -```yaml -minLength: -maxLength: -``` - -Length is measured in Unicode code points. `maxLength` MUST be greater than or equal to `minLength` when both are present. - -### 9.8 Enumerations - -```yaml -enum: [v1, v2, ...] -``` - -Enumeration values are scalar Blue values. They MAY be authored as bare scalars when unambiguous, or as explicit scalar nodes with `type` and `value` when type disambiguation is required, for example for large integers represented as quoted canonical decimal text. Equality is by parsed scalar value, effective scalar type, and canonical JSON value semantics, not by textual rendering. - -`enum` comparison is performed after preprocessing and scalar type inference. Therefore the untyped enum entry `1` is an `Integer`, while `1.0` and `1e0` are `Double`. A quoted decimal string is Text unless authored as an explicit `Integer` scalar node. - -Example with a large integer enum value: - -```yaml -schema: - enum: - - 1 - - 1.0 - - type: Integer - value: "9007199254740992" -``` - -The first two enum entries above are distinct because their effective scalar types are different. - -There is no separate `const` keyword. A fixed value in a type enforces a constant. - -### 9.8.1 Enumeration normalization (normative) - -`enum` is a set of allowed scalar identities. Authoring order is not semantic. - -During schema validation, schema merge, and canonicalization, each enum entry MUST be normalized to its typed scalar identity: effective scalar type plus canonical scalar value. Duplicate entries with the same typed scalar identity are redundant and MUST be removed in the effective schema. - -The canonical enum representation MUST sort entries by the RFC 8785 canonical JSON byte sequence of their typed scalar identity form. If two entries have identical canonical bytes, they are duplicates and only one is retained. - -Therefore these schemas are semantically equivalent and MUST canonicalize identically: - -```yaml -schema: - enum: [A, B] -``` - -```yaml -schema: - enum: [B, A, A] -``` - -The effective canonical enum contains `A` and `B` once each, in the canonical ordering defined above. - -### 9.9 Schema merge rules (normative) - -When schemas accumulate along the type chain, implementations MUST merge keyword constraints as follows: - -| Keyword | Merge rule | Failure case | -|---|---|---| -| `required` | logical OR | never, for the keyword itself | -| `minItems` | maximum | merged `minItems > maxItems` | -| `maxItems` | minimum | merged `maxItems < minItems` | -| `uniqueItems` | logical OR | never, for the keyword itself | -| `minFields` | maximum | merged `minFields > maxFields` | -| `maxFields` | minimum | merged `maxFields < minFields` | -| `minimum` | strongest lower bound | incompatible with upper bounds | -| `maximum` | strongest upper bound | incompatible with lower bounds | -| `exclusiveMinimum` | strongest exclusive lower bound | incompatible with upper bounds | -| `exclusiveMaximum` | strongest exclusive upper bound | incompatible with lower bounds | -| `multipleOf` | all constraints must hold; integer constraints MUST be merged to their LCM; Double constraints MUST be evaluated by exact rational arithmetic over IEEE 754 binary64 values under §9.6 | no possible numeric value satisfies all constraints | -| `minLength` | maximum | merged `minLength > maxLength` | -| `maxLength` | minimum | merged `maxLength < minLength` | -| `enum` | normalize both sides under §9.8.1, then intersect by typed scalar identity; canonical effective enum is duplicate-free and sorted under §9.8.1 | empty intersection | - -For lower/upper-bound interactions, an exclusive bound at the same numeric value is stricter than an inclusive bound. For example, `minimum: 5` merged with `exclusiveMinimum: 5` yields `exclusiveMinimum: 5`. - ---- - -## 10. Resolution and Resolved Views - -### 10.1 Goal (normative) - -Resolution produces a **Resolved View**: a fully materialized, type-merged, schema-validated semantic view of a Source Node. - -A Resolved View is the correct input for type checks and semantic validation. It is not necessarily direct BlueId Input because it may contain inherited or materialized fields that are derivable from the type chain. - -To compute Content BlueId, the Resolved View MUST be canonicalized into a Canonical Identity Input (§13) and then hashed (§14). - -### 10.2 Resolution algorithm (normative) - -Given a Source Node `S`, a conforming implementation performs: - -1. **Preprocess** `S` (§6), producing a Preprocessed Document. -2. **Resolve type chain.** If `S.type` exists, recursively resolve it. If the type is a pure reference, follow it through a provider and verify the fetched content (§12.4). The result is the ancestor Resolved View `A`. -3. **Merge ancestor and source.** Merge `A` into target `T`, then merge `S` into `T`: - - **Root labels:** when merging a type into an instance root, do not copy the type root's `name` or `description` onto the instance root (§4.6). - - **Values:** copy if absent; if both are present, they must be equal under fixed-value equality (§8.3). - - **Types:** assign and propagate under §8. - - **Schema:** accumulate under §9. - - **Object fields:** merge recursively; children must remain compatible. - - **Lists:** merge under §11. - - **Contracts:** preserve and merge as identity-bearing content under §4.4; do not execute. -4. **Validate schema** after merging. -5. **Produce the Resolved View.** Implementations MAY freeze it into a **Resolved Snapshot** when immutability matters. - -Schema validation is performed after inherited and instance values are merged at a node. Therefore an inherited schema applies to inherited fixed values, type-derived fields, and instance-supplied values in the final Resolved View. - -Type-chain resolution is depth-first: the effective ancestor type is resolved before it is merged into the descendant target. A resolver MUST track the active type-resolution stack for cycle detection. - -### 10.2.1 Type-chain cycle detection (normative) - -Type-chain cycles are invalid for Blue Language 1.0 resolution. - -If resolving a node requires resolving a type that is already present on the active type-resolution stack, resolution MUST fail deterministically with a type-cycle error. - -Example invalid cycle: - -```yaml -# A -name: A -type: - blueId: - -# B -name: B -type: - blueId: -``` - -Circular-set BlueIds (§15) identify cyclic document sets. They do not make cyclic inheritance or cyclic type chains resolvable. Blue Language 1.0 does not define fixed-point type semantics. - -### 10.2.2 Reference resolution pseudocode (informative) - -The following pseudocode is informative, but illustrates the required order of operations. - -```text -resolve(source, provider): - S = preprocess(source) - if S.type exists: - T_ref = normalize_type_reference(S.type) - T_node = materialize_if_reference(T_ref, provider) - A = resolve(T_node, provider) - else: - A = empty node - R = merge_as_instance(ancestor=A, instance=S, path="/") - validate_schema_recursively(R) - return ResolvedView(R, provenance) - -merge_as_instance(ancestor, instance, path): - T = copy_type_derived_content(ancestor, path) - if path == "/" and ancestor is the effective type of instance: - do not copy ancestor.name or ancestor.description to T - merge reserved metadata using field-specific rules - merge ordinary child fields recursively - merge lists using §11 - merge contracts using §4.4 - reject fixed-value, type, schema, or payload-kind conflicts - record provenance for each retained contribution - return T -``` - -Precise implementation structure is not normative. The observable Resolved View, provenance sufficient for canonicalization, validation behavior, and resulting Content BlueId are normative. - -### 10.3 Resolution provenance (normative) - -A conforming implementation MUST track enough provenance to canonicalize deterministically. For each resolved path, the implementation MUST be able to determine whether the content was: - -- **instance-supplied** by the Source Document after preprocessing; -- **type-derived** from an ancestor type; -- **provider-materialized** from a `blueId` reference; -- **preprocessing-derived** from mandatory or declared preprocessing; -- **merge-derived** from compatible instance and type contributions. - -The exact internal representation is implementation-defined, but the canonicalization result MUST be deterministic and conform to §13. - -### 10.4 Identity guarantee (normative) - -Resolution preserves semantic identity. A Source Document and its Resolved View have the same Content BlueId when the Resolved View is canonicalized. - -Implementations MUST NOT assume that directly hashing a Resolved View produces the Content BlueId. - -### 10.5 Provider failures (normative) - -A conforming implementation MUST materialize referenced content when that content is required for resolution, canonicalization, expansion, collapse, or validation. If required content is unavailable, the operation MUST fail deterministically. Implementations MUST NOT silently substitute empty content for missing references. - -### 10.6 Limits (normative) - -Implementations SHOULD support path and depth limits to bound materialization of large graphs. Limits affect materialization, not semantic meaning. If a limit prevents content required for resolution, resolution MUST fail or return an explicitly incomplete view, depending on the declared API. An incomplete view MUST NOT be used for Content BlueId. - ---- - -## 11. Lists, Merge Policies, and List Control Forms - -### 11.1 Authoring model (normative) - -A list field SHOULD be authored in typed form when list semantics matter: - -```yaml -: - type: List - itemType: - mergePolicy: append-only | positional - items: - - ...elements... -``` - -A surface list is permitted for simple cases: - -```yaml -tags: [a, b, c] -``` - -Typed form is REQUIRED when `mergePolicy`, anchors, or overlays are used. - -Every element of a resolved list with an effective `itemType` MUST resolve as an instance of, or subtype-compatible with, the effective `itemType`. If an item cannot be resolved or is incompatible with `itemType`, validation MUST fail. - -If `itemType` is omitted and no effective inherited `itemType` exists, list elements are unconstrained by item type. - -### 11.2 Allowed item forms inside `items` (normative) - -Each item inside `items` MUST be exactly one of the following forms after Source Document preprocessing. - -#### Normal element - -```yaml -- -``` - -A normal element is content. - -#### Append anchor - -```yaml -- $previous: - blueId: -``` - -Rules: - -- `$previous` is allowed only as the first item. -- The shape MUST be exactly one top-level `$previous` key whose value is an object with exactly one `blueId` key. -- `$previous` is never content. - -#### Positional overlay - -Map overlay: - -```yaml -- $pos: 1 - ...overlay fields... -``` - -Replacement overlay for an object: - -```yaml -- $pos: 1 - $replace: - type: Address - city: Warsaw -``` - -Replacement overlay for a list: - -```yaml -- $pos: 1 - $replace: - items: - - A - - B -``` - -Replacement overlay for a pure reference: - -```yaml -- $pos: 1 - $replace: - blueId: X -``` - -Rules: - -- `$pos` MUST be a non-negative integer using zero-based indexing. -- `$pos` is valid only when `mergePolicy: positional`. -- A `$pos` item without `$replace` is a map overlay. It is valid only when the inherited element at that index is an object-compatible node. If the inherited element is scalar, list, or pure reference, the overlay MUST use `$replace` and remain type-compatible. -- `$pos` overlays are consumed by resolution and do not appear as content in the final list. -- `$replace` is valid only inside a `$pos` item. Its value is a full Blue node used to replace the inherited element, subject to type and schema compatibility. -- For scalar replacement, the concise form below is equivalent to `$replace: { value: B }`: - -```yaml -- $pos: 1 - value: B -``` - -The `value` form MUST NOT be used to carry list or object replacements. Use `$replace` for non-scalar replacements. - -#### Placeholder element - -```yaml -- $empty: true -``` - -`$empty: true` is content. It is a real element that occupies a position and affects BlueId. It is distinct from `null`, `{}`, and `[]`. - -The shape MUST be exactly one top-level `$empty` key whose value is the boolean `true`. `$empty: false`, `$empty: null`, and `$empty` with sibling fields are invalid as list placeholder elements. - -### 11.3 Scope of list control keys (normative) - -The special keys `$previous`, `$pos`, `$replace`, and `$empty` are recognized only as top-level keys of elements inside a list payload. - -`$empty` is valid in any list payload. - -`$previous`, `$pos`, and `$replace` are list overlay controls. They are valid only when the list is being resolved as a typed or overlay-capable list. Authors SHOULD use the typed list form when using these controls. - -Outside list-control position, `$previous`, `$pos`, `$replace`, and `$empty` are ordinary field names unless another specification gives them meaning. They do not act as list controls outside list elements. - -### 11.4 Default merge policy (normative) - -If no effective `mergePolicy` is inherited and no `mergePolicy` is authored on the list, resolvers MUST assume: - -```yaml -mergePolicy: positional -``` - -If an inherited list has an effective `mergePolicy`, a descendant list overlay that omits `mergePolicy` inherits that effective policy. A descendant MAY repeat the same `mergePolicy`. - -A descendant MUST NOT change an inherited `mergePolicy`. If an effective `mergePolicy` is inherited, omission by the descendant means inheritance, not defaulting. If no policy is inherited and no policy is authored, the effective default is `positional`. - -In particular, `append-only` MUST NOT be weakened to `positional`. - -For histories, ledgers, timelines, and append-only logs, authors MUST specify: - -```yaml -mergePolicy: append-only -``` - -### 11.5 Semantics of `null`, `{}`, `[]`, and `$empty` (normative) - -Blue distinguishes object-field absence from list position. - -#### Object fields - -In object fields, `null` means no information. Before hashing: - -- fields whose value is `null` MUST be omitted; -- fields whose value normalizes to an empty object `{}` MUST be omitted; -- empty lists `[]` MUST be preserved. - -This removal is recursive and may cascade. - -#### List elements - -List elements are positional. Implementations MUST NOT delete list elements during cleaning, because doing so changes list length and shifts later indices. - -In Source Documents, a list element that is `null`, an empty object `{}`, or an object that recursively normalizes to an empty object after object-field cleaning MUST be normalized to: - -```yaml -$empty: true -``` - -It MUST NOT be deleted from the list, because list position is content. - -In Canonical Identity Input and BlueId Input, `null` list elements and empty-object list elements MUST NOT appear. They MUST already have been normalized to `$empty: true` or rejected. - -The marker `$empty: true` is content. It occupies a list position and affects BlueId. - -Empty lists `[]` are preserved as list elements and are distinct from `$empty: true`. - -Consequences: - -```text -id([A, null, B] after preprocessing) == id([A, {$empty: true}, B]) -id([A, null, B] after preprocessing) != id([A, B]) -id([A, {}, B] after preprocessing) == id([A, {$empty: true}, B]) -id([A, [], B]) != id([A, {$empty: true}, B]) -``` - -### 11.6 Merge semantics (normative) - -Let `P` be the resolved parent list and `C` be the child overlay list. - -#### `append-only` - -For `mergePolicy: append-only`: - -- inherited indices `< length(P)` MUST NOT be modified or deleted; -- `$pos` overlays are forbidden; -- normal items after the inherited prefix are appended; -- an optional `$previous` anchor may appear as the first child item. - -Errors: - -- any `$pos` overlay; -- malformed `$previous`; -- `$previous` not first; -- repeated `$previous`; -- attempted modification, removal, or reordering of the inherited prefix. - -#### `positional` - -For `mergePolicy: positional`: - -- `$pos: i` refines inherited index `i`, where `0 <= i < length(P)`; -- map overlays merge field-wise, subject to type and schema compatibility; -- `$replace` overlays replace the inherited element, subject to compatibility; -- scalar `value` overlays replace the inherited element with a scalar node, subject to compatibility; -- normal items without `$pos` are appended after the inherited prefix in author order; -- reordering, removal, and gaps within the inherited prefix are forbidden. - -Errors: - -- `$pos` missing or non-integer; -- `$pos` out of range; -- duplicate overlays for the same index; -- type or schema incompatibility at the index; -- attempted reordering or removal of parent elements; -- `value` used as a non-scalar positional replacement. - -### 11.7 `$previous` validation (normative) - -`$previous` is a resolution-time anchor. - -During resolution, the resolver MUST verify that the inherited prefix hashes to `$previous.blueId`. If it does not match, resolution MUST fail. - -During direct Node BlueId calculation of valid BlueId Input that already contains a leading `$previous`, the anchor MAY be used as a list-fold seed (§14.8). Validity of the anchor is a precondition of the input. An implementation performing direct Node BlueId calculation without resolution context MAY reject `$previous` inputs. - -A direct hasher MUST NOT silently ignore `$previous` and recompute when it cannot verify the prefix. A direct hasher has no provider or inheritance context and therefore cannot determine whether an anchor is stale. - -### 11.8 List conformance checklist (normative) - -Implementations supporting lists MUST satisfy: - -- `id([])` is defined and distinct from absent values and cleaned object fields; -- `[A]` hashes differently from `A`; -- `[[A, B], C]` hashes differently from `[A, B, C]`; -- Source list `[A, null, B]` normalizes to `[A, {$empty: true}, B]`, not `[A, B]`; -- Source list `[A, {}, B]` normalizes to `[A, {$empty: true}, B]`, not `[A, B]`; -- Source list `[A, {x: null}, B]` normalizes to `[A, {$empty: true}, B]`, not `[A, B]`; -- `$previous` is recognized only as the first item; -- `$previous` mismatch fails resolution; -- `append-only` rejects `$pos`; -- inherited `append-only` remains effective when a child overlay omits `mergePolicy`; -- `positional` accepts valid `$pos` overlays and rejects duplicate or out-of-range overlays; -- `$empty: true` remains content and affects BlueId; -- malformed `$empty` placeholder items are rejected; -- object-field cleaning removes `null` and object fields that normalize to `{}`, but does not delete list positions. - -### 11.9 Worked examples (informative) - -Present-empty vs absent: - -```yaml -# Absent -doc: {} - -# Present-empty -doc: - list: - type: List - items: [] -``` - -Append-only timeline: - -```yaml -# Parent -entries: - type: List - itemType: Timeline Entry - mergePolicy: append-only - items: - - { type: Timeline Entry, ts: "2025-09-01T12:00:00Z", message: A } - - { type: Timeline Entry, ts: "2025-09-01T12:05:00Z", message: B } - -# Child -entries: - type: List - itemType: Timeline Entry - mergePolicy: append-only - items: - - $previous: { blueId: PrevId } - - { type: Timeline Entry, ts: "2025-09-01T12:10:00Z", message: C } -``` - -Positional hole and refinement: - -```yaml -# Parent -entries: - type: List - mergePolicy: positional - items: - - A - - $empty: true - - C - -# Child -entries: - type: List - mergePolicy: positional - items: - - $pos: 1 - value: B -# Resolved: [A, B, C] -``` - ---- - -## 12. References, Providers, Expansion, and Collapse - -### 12.1 Providers (informative) - -A **provider** is any mechanism that resolves a BlueId to node content. Examples include an in-memory map, a local registry, a database, or a content-addressed network store. - -This specification defines only the semantic role of providers. It does not define transport, trust, availability, or persistence protocols. - -### 12.2 Provider trust model (normative/informative) - -A provider MAY be untrusted. A conforming implementation MUST verify provider-returned content against the requested BlueId before using it for expansion, resolution, or canonicalization. - -BlueId verification provides content integrity: the returned content matches the requested content address. It does not provide authenticity, authorization, availability, freshness, confidentiality, or provenance of the provider itself. - -If a provider returns missing content, malformed content, content that does not verify under the declared provider mode, or content that requires unsupported resolution, the operation MUST fail deterministically. - -### 12.3 Provider content form (normative) - -A provider used to dereference a plain `blueId: X` in expansion, resolution, or canonicalization MUST return content whose direct Node BlueId is `X`, unless the provider is explicitly declared as a Source Document provider. - -The portable provider model for Blue Language 1.0 is a verified BlueId provider: provider content is already valid BlueId Input or canonical content. Implementations MUST verify the returned content by direct Node BlueId before using it. - -A Source Document provider MAY be supported as an implementation extension or registry mode. Such a provider verifies returned content by Content BlueId, not direct Node BlueId. This requires declaring the Blue Language version, preprocessing environment, provider state, and registry bindings used for Content BlueId calculation. A Source Document provider is not the default portable provider model. - -A conforming implementation MUST NOT silently accept Source Document provider content under the ordinary BlueId provider model. - -### 12.4 Plain BlueId provider verification (normative) - -When a provider returns materialized content for `blueId: X`, the implementation MUST verify that the returned content has Node BlueId `X`. If verification fails, expansion or resolution MUST fail deterministically. - -Implementations MUST NOT silently use provider content whose computed BlueId differs from the requested BlueId. - -### 12.5 Cyclic-set member provider verification (normative) - -A cyclic-set member BlueId of the form `#` cannot be verified by ordinary single-node Node BlueId calculation. - -A provider that returns content for a cyclic-set member BlueId MUST either: - -1. return a verified cyclic-set envelope containing the full ordered set needed to recompute `MASTER` and select member `index`; -2. be a trusted registry binding whose cyclic-set membership and `MASTER` were verified as part of the release artifact; or -3. fail deterministically. - -An implementation MUST NOT verify `#` by hashing the returned member alone. - -### 12.6 Expansion (normative) - -**Expansion** materializes content referenced by `blueId` from a provider without changing identity. - -Given: - -```yaml -field: - blueId: X -``` - -expansion fetches the content for `X`, verifies it (§12.4), and materializes it in place or side-by-side, enabling nested references to expand recursively. - -Expansion is a view operation. It changes representation, not meaning. - -Expansion MUST NOT change Node BlueId. A pure reference hashes to its target BlueId. Materialized content contributes the same identity when the materialized content verifies to that BlueId. - -Implementations SHOULD support path and depth limits to avoid runaway traversal of large graphs. Limits affect only materialization, not identity. - -### 12.7 Collapse (normative) - -**Collapse** is the inverse of expansion. It replaces a materialized subtree with a pure reference `{ blueId: X }` when the subtree's Node BlueId is known to be `X`. - -Collapse is optional as an exposed view operation. If an implementation exposes collapse, the operation MUST satisfy this section and MUST preserve Node BlueId. A collapsed result MUST be a pure reference and MUST NOT produce mixed `blueId` forms. - -Minimized Overlays MAY use collapse when the minimization rules permit it (§13). Canonical Identity Input MUST follow the deterministic canonicalization rules. - -### 12.8 Graph boundary (normative) - -A Blue Document need not be a closed tree. A `{ blueId: ... }` reference may point outside the selected document. Implementations materialize referenced content only as needed and within configured limits. - -### 12.9 Blue Language view paths (normative when exposed) - -Blue Language view paths are implementation-facing selectors used for expansion limits, collapse limits, diagnostics, and provenance. They are not Blue content and do not affect BlueId. - -A conforming implementation that exposes path-limited expansion, collapse, or diagnostics MUST support RFC 6901 JSON Pointer paths over the abstract Blue node model: - -- the empty string `""` selects the root node; -- `/field` selects an object field named `field`; -- `/items/0` selects list payload item index `0` in the abstract node model; -- `~0` represents `~`, and `~1` represents `/`, following RFC 6901. - -The path `/` selects an object field whose key is the empty string. Since empty object-field names are valid JSON member names but are not recommended in portable Blue documents, implementations MUST still treat `/` according to RFC 6901 if exposed. - -The wildcard `*`, such as `/spent/*`, is not part of the required Blue Language 1.0 path grammar. Implementations MAY support wildcards as an extension, but portable conformance fixtures MUST use RFC 6901 paths unless a future path-selector specification defines more. - ---- - -## 13. Canonicalization and Minimization - -### 13.1 Distinction (normative) - -Blue defines two related but different operations on a Resolved View. - -**Minimization** is any semantics-preserving reduction of a Resolved View into a smaller overlay. Different minimizers MAY produce different serialized forms. - -**Canonicalization** is the deterministic identity-input derivation used to compute Content BlueId. For a given Resolved View and the same provider state required by resolution, there is exactly one Canonical Identity Input. - -### 13.2 Canonical Identity Input (normative) - -A **Canonical Identity Input** is the deterministic identity form derived from a Resolved View. It contains the deterministic identity-bearing content needed for BlueId calculation. It may contain final canonical payloads, including final list payloads, that are not ordinary Source overlays. A Canonical Identity Input MUST be valid BlueId Input. It is not required to be accepted as a Source Document or to re-resolve under ordinary Source overlay semantics. - -The Content BlueId of a Source Document is the Node BlueId of its Canonical Identity Input. - -A Canonical Identity Input MUST NOT contain `blue`, unresolved aliases, `$previous`, `$pos`, `null` list elements, or empty-object list elements. - -The re-resolution guarantee belongs to Minimized Overlay (§13.3). A Canonical Identity Input and a Minimized Overlay MAY have different serialized forms and different direct Node BlueIds when hashed outside the full Source identity pipeline. - -### 13.3 Minimized Overlay (normative) - -A **Minimized Overlay** is an author-facing reduced overlay that re-resolves to the same Resolved View. - -A conforming implementation MUST implement canonicalization. A conforming implementation MAY expose author-facing minimization. If it does, every Minimized Overlay it produces MUST re-resolve to the same Resolved View and MUST produce the same Content BlueId through the full identity pipeline. - -Optional author-facing minimizers MAY produce different Minimized Overlays. Such overlays MAY have different direct Node BlueIds, but when processed through the full identity pipeline they MUST produce the same Content BlueId. - -Unlike Canonical Identity Input, a Minimized Overlay MAY contain authoring conveniences such as `$previous`, `$pos`, and `$replace` when those controls are valid Source overlay controls. - -### 13.4 Canonicalization requirements (normative) - -Given a Resolved View `R`, canonicalization MUST: - -- preserve all instance contributions that are not derivable from the type chain; -- remove fields fully derivable from the type chain; -- preserve instance-level `name` and `description` when present on the instance; -- not inherit top-level `name` or `description` from the type; -- preserve instance-fixed values that are not derivable from the type chain; -- replace materialized type objects with canonical `type: { blueId: ... }` references when their BlueId is known; -- ensure the Canonical Identity Input contains no type aliases; if an instance supplied a type alias, preprocessing MUST replace it with the canonical `type: { blueId: ... }` reference before resolution; -- for provider-materialized content, preserve the original pure reference when that reference is an instance contribution and the materialized subtree contributes no additional instance-supplied content; -- remove the `blue` directive if present, because it is invalid after preprocessing; -- normalize list placeholders so that list `null` and empty-object elements become `$empty: true`; -- consume all `$pos` overlays and produce final canonical list content; -- produce valid BlueId Input. - -Schema objects included in Canonical Identity Input MUST use normalized effective schema form. In particular, `enum` values are duplicate-free and sorted under §9.8.1, and integer `multipleOf` constraints are represented by the merged LCM value rather than by raw inherited/descendant contributions. - -### 13.5 Canonicalization as deterministic diff (normative) - -Canonicalization can be understood as a deterministic diff between the Resolved View and the resolved ancestor view contributed by the effective type chain. - -For each node: - -1. If the node has an effective type, include the canonical type reference unless the type reference itself is fully derivable at that path and not required by the canonical identity form. -2. For each reserved metadata field other than `type`, include it only when it is an instance contribution that is not derivable from the ancestor view, except where this specification requires preservation. -3. For each ordinary child field, omit it when the child is fully derivable from the ancestor view. Otherwise include the canonical identity input of the child. -4. For scalar values, omit an inherited fixed value and include an instance value not derivable from the ancestor. -5. For lists, use the canonical list rules in §13.6. -6. After the identity input is constructed, apply BlueId input normalization and object-field cleaning. Empty object fields are omitted. Empty lists are preserved. - -Implementations MUST make all tie-breakers deterministic and covered by conformance vectors. - -### 13.5.1 Canonicalization tie-breakers (normative) - -When multiple candidate identity inputs would represent the same Resolved View, the Canonical Identity Input MUST be selected by the following tie-breakers, in order: - -1. **Omit derivable non-list content.** A field, metadata entry, or non-list subtree that is fully derivable from the effective type chain MUST be omitted from the Canonical Identity Input, unless another rule in this section explicitly requires it. **List payloads are special:** for list nodes, §13.6 overrides this general omission rule. Canonicalization of a list produces the final canonical list payload for identity calculation, including inherited prefix elements, positional refinements, append-only appends, and `$empty` placeholders after normalization. -2. **Preserve non-derivable instance content.** Content supplied by the instance or Source Document and not derivable from the type chain MUST be preserved. -3. **Use pure references for referenced ancestors/types.** A materialized type or referenced ancestor whose BlueId is known MUST be represented as `{ blueId: X }` in type positions and other reference-preserving positions. -4. **Preserve source pure references materialized only for resolution.** If a Source Document provided a pure reference and the provider materialized it only to resolve or validate content, the Canonical Identity Input MUST prefer the original pure reference form unless the instance supplied an overlay that must be represented. -5. **Consume overlay controls.** `$pos`, `$replace`, `$previous`, source list `null`, and empty-object list elements MUST NOT appear in Canonical Identity Input. Their effects must be represented as ordinary canonical content. -6. **No authoring aliases.** Type aliases and `blue` preprocessing directives MUST NOT appear in Canonical Identity Input. -7. **Deterministic map ordering.** When serializing helper maps or canonical JSON, property order is the order defined by RFC 8785 canonical JSON. No locale-sensitive ordering, implementation insertion order, or host map order is permitted. -8. **Smallest semantic identity input wins.** If two candidate identity inputs both satisfy the rules above, the one with fewer non-derivable fields and fewer materialized subtrees wins. If still tied, the RFC 8785 canonical JSON byte sequence of the candidate identity input is compared lexicographically and the smaller byte sequence wins. - -These rules are part of the Blue Language 1.0 identity definition and MUST be implemented consistently. The conformance fixture suite provides examples but does not replace these rules. - -### 13.6 Canonical list rules (normative) - -Canonical list rules produce final list payload content for identity calculation. - -For list payloads, final canonical list content is the canonical identity form. This rule overrides the general "omit derivable content" tie-breaker in §13.5.1. Blue Language 1.0 does not define a canonical list-diff representation. - -For a list with no inherited prefix, the Canonical Identity Input contains the canonicalized full list. - -For an inherited list under `mergePolicy: append-only`, a Minimized Overlay MAY use a valid `$previous` anchor followed by appended elements. A Canonical Identity Input MUST NOT contain `$previous`. Canonicalization MUST produce the final canonical list payload before hashing. Implementations MAY internally optimize list hashing by using a verified inherited-prefix BlueId, but that optimization is not part of the serialized Canonical Identity Input. - -For an inherited list under `mergePolicy: positional`, a Minimized Overlay MAY represent inherited-index refinements using `$pos` overlays. A Canonical Identity Input MUST NOT contain `$pos`. Canonicalization MUST apply all positional overlays and produce the final canonical list payload before hashing. - -A final canonical list payload in Canonical Identity Input is identity input, not an instruction to append to or refine an inherited list under ordinary Source overlay semantics. - -### 13.7 Deterministic collapse during minimization (normative) - -A Minimized Overlay MAY collapse a subtree to `{ blueId: X }` only when: - -1. the subtree's Node BlueId is known to be `X`; -2. provider verification has established that `X` identifies that content if the subtree came from a provider; -3. collapse at that path is deterministic under the implementation's declared minimization rules; -4. the collapsed overlay re-resolves to the same Resolved View. - -A Canonical Identity Input MUST follow the deterministic canonicalization rules. Unless this specification explicitly requires collapse at a path, Canonical Identity Input MUST prefer the materialized canonical identity form. Optional collapse is an author-facing minimization feature, not a source of variation in Content BlueId. - -A Canonical Identity Input MUST NOT depend on implementation-local collapse preferences. - ---- - -## 14. BlueId Algorithm - -### 14.1 Hash function (normative) - -Let: - -```text -H(x) = Base58(SHA-256(RFC 8785 canonical JSON of x)) -``` - -BlueId is computed bottom-up over canonical BlueId Input using `H`. - -### 14.2 Context-sensitive cleaning and placeholder normalization (normative) - -Before hashing, implementations MUST normalize BlueId Input context-sensitively. - -#### Object-field cleaning - -For object fields: - -- remove fields whose value is `null`; -- remove fields whose value normalizes to an empty object `{}`; -- preserve fields whose value is an empty list `[]`; - -This removal is recursive and may cascade. - -#### List-element rules - -For list elements: - -- list elements MUST NOT be deleted merely because they are `null` or `{}`; -- in Source Documents, `null`, `{}`, and elements that recursively clean to empty objects MUST have been normalized to `$empty: true` before BlueId calculation; -- in BlueId Input, `null` and `{}` list elements are invalid; -- `[]` is preserved as an empty list element; -- `$empty: true` is preserved as placeholder content. - -This rule preserves list length, order, and positional meaning. - -In object-field context, an object that becomes empty after cleaning is omitted. In list-element context, a Source element that becomes empty after recursive cleaning is normalized to `$empty: true` before BlueId Input is produced. Direct BlueId Input MUST NOT contain raw empty-object list elements. - -#### Root normalization - -The root of BlueId Input is never omitted by cleaning. - -If the root is an empty object `{}`, its Node BlueId is `H({})`. - -If object-field cleaning causes the root object to become empty, the root remains `{}` and hashes as `H({})`. - -A root `null` value is not valid BlueId Input. Source Documents whose root is `null` MUST be rejected. Authors who intend an empty object document MUST write `{}`; authors who intend an empty list document MUST write `[]`. - -### 14.3 Canonical BlueId input normalization (normative) - -The BlueId algorithm hashes the abstract node model, not authoring syntax. - -Direct Node BlueId calculation does not run the full Source Document preprocessing pipeline. However, BlueId input normalization includes the mandatory primitive scalar inference needed to make bare scalar nodes identity-stable across conforming implementations. This inference is limited to the core primitive types listed below and does not apply aliases, imports, `blue` directives, or declared preprocessing transforms. - -Before hashing a Node value: - -- scalar sugar is normalized to scalar payload; -- list sugar is normalized to list payload; -- bare scalar payloads with no explicit type are assigned the corresponding core primitive type reference; -- integer values outside the safe JSON numeric integer range are represented as quoted canonical decimal text while retaining explicit `Integer` type (§2.4); -- finite `Double` values are converted to their canonical scalar representation; -- pure references are represented exactly as `{ blueId: X }`; -- `blue` is rejected; -- `$pos` is rejected; -- list `null` and empty-object elements are rejected unless already normalized to `$empty: true`. - -Primitive scalar inference for BlueId input normalization uses: - -| Parsed value kind | Inferred type | -|---|---| -| string | `Text` | -| integer numeric token with no decimal point or exponent, or explicitly typed canonical integer text | `Integer` | -| numeric token with a decimal point or exponent, or other non-integer finite number | `Double` | -| boolean | `Boolean` | - -A scalar payload with explicit type uses the explicit type, subject to resolution and validation. - -### 14.4 Scalars (normative) - -For BlueId calculation, every scalar payload node is normalized to a **typed scalar identity form** before hashing. If no explicit effective type is present, the inferred primitive type from §14.3 is inserted. Therefore an untyped Source scalar token `1` hashes as a scalar node with effective type `Integer`, while source tokens `1.0` and `1e0` hash as scalar nodes with effective type `Double`. The effective scalar type is part of identity. - -A bare scalar payload is represented as the canonical scalar value and, when converted to canonical BlueId input as a node, includes its inferred primitive type unless an explicit type is already present. - -Scalar values are encoded using RFC 8785 canonical JSON value rules after Blue scalar normalization. - -For `Integer`, implementations MUST preserve mathematical integer identity. Integer values outside the safe JSON numeric integer range MUST be encoded as canonical decimal text while retaining `type: Integer` in the canonical BlueId input (§2.4). - -For `Double`, only finite numbers are valid. `NaN`, `Infinity`, and `-Infinity` are invalid Blue scalar values. - -A `Double` value whose canonical JSON number renders as an integer-looking number, such as `1`, remains distinct from `Integer` because the canonical BlueId input retains `type: Double`. Numeric rendering alone does not determine scalar type after preprocessing. - -### 14.4.1 Payload normalization before hashing (normative) - -The BlueId algorithm hashes the abstract Blue node model, not raw JSON/YAML syntax. - -Before map hashing is applied, each node is classified as one of: - -1. pure reference; -2. scalar payload node; -3. list payload node; -4. object payload node; -5. metadata-bearing node. - -A node with a scalar payload and no retained metadata other than its effective scalar type and value hashes as the typed scalar identity form. "Payload-only scalar" does not mean hashing the raw JSON scalar alone; it means hashing the canonical Blue scalar node consisting of the effective primitive type reference and the canonical scalar value. If no explicit effective type is present, the inferred primitive type is inserted before hashing. - -A node with a list payload and no retained metadata other than the payload itself hashes as the list payload. - -Therefore these forms hash identically: - -```yaml -x: 1 -``` - -```yaml -x: - value: 1 -``` - -and these forms hash identically: - -```yaml -x: [a, b] -``` - -```yaml -x: - items: [a, b] -``` - -Thus these Source scalar tokens do not all have the same typed scalar identity unless an explicit type or schema says otherwise: - -```yaml -1 # effective type Integer, value 1 -1.0 # effective type Double, canonical numeric payload may render as 1 -1e0 # effective type Double, canonical numeric payload may render as 1 -``` - -`1.0` and `1e0` are equivalent Double values, but they are not equivalent to Integer `1` because the effective type differs. - -When a node has retained metadata such as `type`, `schema`, `name`, `description`, `itemType`, `mergePolicy`, or `contracts`, it hashes as a metadata-bearing map. In that case, `value` or `items` is the payload field of that metadata-bearing node and participates in map hashing as defined below. - -A node MUST NOT contain more than one payload kind. - -### 14.5 Map hashing (normative) - -Map hashing applies only after payload-only scalar and payload-only list nodes have been normalized as described above. - -If and only if a map is exactly: - -```json -{ "blueId": "" } -``` - -then its BlueId is ``. This is the pure reference short-circuit. - -A map containing `blueId` together with sibling fields is not a pure reference and MUST NOT appear in BlueId Input. - -Otherwise, build the helper map `M` conceptually. Its serialized property order is the order defined by RFC 8785 canonical JSON. Implementations MUST NOT use locale-sensitive collation or implementation insertion order. - -- for `name`, `description`, and `value`, inline their cleaned scalar values; -- for every other key `k` with value `v`, include: - -```json -"k": { "blueId": id(v) } -``` - -Then compute: - -```text -id(map) = H(M) -``` - -This rule ensures nested structure contributes through BlueId rather than through byte shape. It also makes materialized subtrees and pure references identity-equivalent when they have the same BlueId. - -### 14.6 Object fields with `null` (normative) - -Object fields with `null` values are omitted before map hashing: - -```yaml -a: null -b: 1 -``` - -normalizes as: - -```yaml -b: 1 -``` - -If recursive cleaning makes a child object empty, the child field is also omitted. Empty lists are preserved. - -### 14.7 List hashing (normative) - -Lists are hashed using a domain-separated streaming fold over element BlueIds. - -Empty list seed: - -```text -id([]) = H({ "$list": "empty" }) -``` - -Fold step: - -```text -fold(prevId, x) = - H({ - "$listCons": { - "prev": { "blueId": prevId }, - "elem": { "blueId": id(x) } - } - }) -``` - -The object passed to `H` in the fold step is serialized by RFC 8785; therefore property serialization order is determined by RFC 8785, not by the order shown in pseudocode. - -Whole list: - -```text -id([a1, ..., an]) = fold(fold(...fold(id([]), a1)...), an) -``` - -Properties: - -- order is significant; -- multiplicity is preserved; -- lists are not flattened; -- `[A]` is distinct from `A`; -- `[]` is distinct from absent values and cleaned object fields; -- `[A, {$empty: true}, B]` is distinct from `[A, B]`; -- append hashing can be O(delta) when seeded by a valid `$previous` anchor. - -### 14.8 List control normalization before hashing (normative) - -For direct anchored BlueId Input: - -- `$previous` MAY appear only as the first item. -- If present and well-formed, `$previous.blueId` MAY seed the list fold. -- Anchor validity is a precondition of direct anchored BlueId Input. -- A Canonical Identity Input produced by the Content BlueId pipeline MUST NOT contain `$previous`. -- Implementations MAY use a verified prefix BlueId as an internal hashing optimization. - -`$pos` and `$replace` MUST NOT appear in BlueId Input. `$empty: true` remains content and hashes as a normal object element. - -Malformed list controls MUST be rejected. - -### 14.8.1 Canonical JSON examples (informative but behavior-defining through referenced rules) - -#### Large Integer scalar node - -An Integer outside the safe JSON numeric integer range is represented as quoted canonical decimal text with explicit Integer type. - -Canonical BlueId Input shape: - -```yaml -type: - blueId: -value: "9007199254740992" -``` - -Map hashing builds helper map `M` conceptually: - -```json -{ - "type": { "blueId": "" }, - "value": "9007199254740992" -} -``` - -The RFC 8785 canonical JSON byte sequence is the UTF-8 encoding of: - -```json -{"type":{"blueId":""},"value":"9007199254740992"} -``` - -#### Double negative zero - -`Double` values use finite IEEE 754 binary64 semantics. Negative zero and positive zero compare as the same numeric value. Under RFC 8785 canonical JSON, the numeric value canonicalizes as JSON number `0`. - -A Source token such as `-0.0` infers `Double` if no explicit type is provided, but the canonical scalar numeric payload is `0` and the effective `type: Double` preserves the fact that the node is a Double rather than an Integer. - -#### Integer-looking Double - -A Source token such as `1.0` or `1e0` infers `Double`. The canonical JSON representation of the numeric payload may render as `1`, but the effective `type: Double` remains part of canonical BlueId input. Therefore `1` as Integer and `1.0` as Double are distinct Blue values unless an explicit type or schema says otherwise. - -#### List fold helper map ordering - -The list fold step uses the exact object keys `$listCons`, `prev`, and `elem`: - -```json -{"$listCons":{"elem":{"blueId":""},"prev":{"blueId":""}}} -``` - -The example shows the RFC 8785 canonical JSON serialization for these keys. Implementations MUST NOT rely on insertion order or host map order. - -### 14.9 Storage rule (normative) - -A node MUST NOT store its own BlueId as authoritative content. - -Using `{ blueId: ... }` to reference other nodes is permitted and encouraged. A provider or envelope MAY store a node's BlueId out-of-band, but the self-BlueId MUST NOT be treated as part of the node's own content. - -### 14.10 Inputs containing `blue` (normative) - -BlueId Input MUST NOT contain `blue`. A direct hasher MUST reject such input. - ---- - -## 15. Circular Reference Sets - -### 15.1 Purpose - -Some authoring graphs contain direct cycles across documents, for example `Person` references `Dog` and `Dog` references `Person`. Blue supports a combined BlueId for a cyclic set, with stable per-document suffixes. - -### 15.2 ZERO_BLUEID sentinel (normative) - -During cyclic-set calculation, each direct cyclic reference is temporarily replaced with the **ZERO_BLUEID** sentinel: forty-four ASCII `0` characters. - -ZERO_BLUEID is a sentinel only. It MUST NOT appear in finalized BlueId Input. - -During cyclic-set calculation, ZERO_BLUEID and `this#` are permitted only in positions where a BlueId string is expected inside the temporary cyclic-set calculation input. - -They are not valid ordinary BlueId Input and MUST NOT appear in finalized provider-stored content. - -### 15.3 Cyclic-set input (normative) - -The input to the cyclic-set algorithm is a finite set of document roots plus explicit internal reference markers indicating which references point to documents within the set. - -The algorithm applies to a strongly connected cyclic set. Independent strongly connected components SHOULD be processed separately. - -A cyclic-set calculation input MUST contain at least one internal cyclic reference. A set with no internal cyclic references SHOULD be treated as ordinary independent documents rather than as a cyclic set. - -If two cyclic-set members have identical preliminary BlueIds, implementations MUST compare the RFC 8785 canonical JSON byte sequence of their preliminary BlueId input as a deterministic tie-breaker. - -If the tie remains equal, the cyclic-set input is invalid in Blue Language 1.0 unless the members contain an explicit identity-bearing disambiguator before preliminary hashing. Implementations MUST fail cyclic-set calculation with `CircularSetError` rather than assigning arbitrary positions. - -Blue Language 1.0 does not define graph-isomorphism rules for duplicate preliminary cyclic members. - -### 15.4 Cyclic-set algorithm (normative) - -Given a finite set of documents participating in a direct cycle: - -1. Temporarily replace each internal cyclic `blueId` reference with ZERO_BLUEID. -2. Calculate preliminary BlueIds for each document in isolation. -3. Sort documents lexicographically by preliminary BlueId, with the tie-breaking rule from §15.3. -4. Assign positions `#0` through `#(n-1)` according to that order. -5. Rewrite each internal cyclic reference as: - -```yaml -blueId: this# -``` - -where `` is the assigned position of the target document. - -6. Build a list: - -```text -L = [doc#0, doc#1, ..., doc#(n-1)] -``` - -with `this#` references in place. - -7. Compute: - -```text -MASTER = id(L) -``` - -8. The final BlueId of document `i` is: - -```text -MASTER#i -``` - -The **preliminary BlueId input** for each document is the document after replacing each direct internal cyclic `blueId` reference with ZERO_BLUEID and before rewriting those references to `this#`. - -`this#` is accepted only by the cyclic-set calculation API. It MUST NOT appear in stored provider content, ordinary BlueId Input, Source Documents outside explicit cyclic-set serialization, or Canonical Identity Input. - -During preliminary BlueId calculation with ZERO_BLUEID placeholders, a pure reference `{ blueId: ZERO_BLUEID }` is treated as a temporary pure reference whose identity contribution is the sentinel value for the purpose of preliminary ordering only. ZERO_BLUEID MUST NOT be returned as a finalized BlueId. - -During MASTER calculation, pure references `{ blueId: "this#" }` are treated as internal cyclic placeholders as defined by the cyclic-set algorithm, not as ordinary provider references. - -Cyclic-set identity flow: - -```text -authoring refs - | - v -replace internal refs with ZERO_BLUEID - | - v -preliminary ids -> sort -> assign #0..#(n-1) - | - v -rewrite internal refs to this#k - | - v -MASTER = id([doc#0, doc#1, ...]) - | - v -final ids = MASTER#0, MASTER#1, ... -``` - -### 15.5 BlueId grammar for cyclic sets (normative) - -A cyclic-set member BlueId has the form: - -```text -# -``` - -where `MASTER` is a plain BlueId and `index` is a non-negative decimal integer with no leading zeros, except for the single digit `0`. - -`this#` is an algorithm-internal placeholder. It is accepted only by an implementation API explicitly performing cyclic-set calculation over a declared finite cyclic set. It MUST be rejected by ordinary parsing, preprocessing, resolution, provider storage, expansion, canonicalization, and direct BlueId calculation outside that cyclic-set calculation API. - -### 15.6 Example (informative) - -```yaml -# Dog (#0 after sorting) -name: Dog -owner: - type: - blueId: this#1 -breed: - type: Text - -# Person (#1 after sorting) -name: Person -pet: - type: - blueId: this#0 -``` - -If `MASTER = 12345...`, then: - -```text -Dog = 12345...#0 -Person = 12345...#1 -``` - ---- - -## 16. Conformance Vectors - -The Blue Language 1.0 conformance suite, canonical core registry, and this prose specification jointly define Blue Language 1.0. The prose rules are normative, the registry supplies exact identity-bearing core type nodes and BlueIds, and the fixtures provide behavior-defining executable examples. - -A fixture package identity MUST be published with the Blue Language 1.0 release. A conforming implementation MUST report which fixture package identity it passes. - -If the prose specification, registry, and fixture package conflict, the release artifact is invalid and MUST be corrected. Implementations MUST NOT guess which artifact wins. - -Conformance vectors are behavior-defining. A conforming Blue Language 1.0 implementation MUST pass all vectors in this section and all machine-readable fixtures in the Blue Language 1.0 conformance suite. - -The labels `B`, `R`, and `F` identify fixture categories: BlueId algorithm, resolution/canonicalization, and provider/full-graph behavior. They do not define separate conformance levels. - -### 16.1 BlueId algorithm vectors - -- **B1.** `id([])` is defined and distinct from absent values and cleaned object fields. -- **B2.** `[A]` hashes differently from `A`. -- **B3.** `[[A, B], C]` hashes differently from `[A, B, C]`. -- **B4.** `x: 1` and `x: { value: 1 }` produce the same Node BlueId after canonical input normalization. -- **B5.** `x: [a, b]` and `x: { items: [a, b] }` produce the same Node BlueId. -- **B6.** A map exactly `{ blueId: X }` hashes to `X`. -- **B7.** Object-field cleaning removes `null` fields and fields that normalize to empty objects. -- **B8.** Cleaning preserves `[]`. -- **B9.** A node containing `blue` is rejected as direct BlueId Input. -- **B10.** A map mixing `blueId` with sibling fields is rejected as BlueId Input. -- **B11.** Primitive scalar inference assigns `Text`, `Integer`, `Double`, and `Boolean` deterministically. -- **B12.** `$empty: true` remains content and affects BlueId. -- **B13.** Direct BlueId Input containing a `null` list element is rejected. -- **B14.** Direct BlueId Input containing an empty-object list element is rejected unless it has already been normalized to `$empty: true` before direct hashing. -- **B15.** `[A, {$empty: true}, B]` hashes differently from `[A, B]`. -- **B16.** Integer values above `9007199254740991` or below `-9007199254740991` are represented as quoted canonical decimal text with explicit `Integer` type. -- **B17.** `this#` is rejected outside the explicit cyclic-set calculation API. -- **B18.** A source numeric token `1` infers `Integer`; source numeric tokens `1.0` and `1e0` infer `Double`; explicit `type: Double` remains Double even when the canonical JSON number renders as `1`. -- **B19.** Root `{}` is valid BlueId Input and hashes as an empty object; it is not omitted. -- **B20.** Root `null` is invalid as Source Document root and as BlueId Input. -- **B21.** Plain BlueIds validate as canonical Base58 encodings of exactly 32 bytes; invalid alphabet characters, non-canonical encodings, wrong decoded length, and plain ID strings containing `#` are rejected. -- **B22.** `$empty` list placeholder shape is exactly `{ "$empty": true }`; malformed `$empty` items are rejected. -- **B23.** `Double` negative zero canonicalizes to numeric payload `0` while retaining Double type. -- **B24.** `Double` overflow is rejected. -- **B25.** Integer-looking Double canonical rendering retains Double type. -- **B26.** Payload-only scalar hashing uses typed scalar identity form, not raw JSON scalar hashing. -- **B27.** Enum order and duplicate entries do not affect effective canonical schema identity. -- **B28.** `Double` `multipleOf` is evaluated by exact rational arithmetic over IEEE 754 binary64 values. -- **B29.** A cyclic-set input with duplicate preliminary member inputs fails unless the members contain identity-bearing disambiguators before preliminary hashing. - -### 16.2 Resolution and canonicalization vectors - -- **R1.** Preprocessing removes `blue` and applies baseline transforms before resolution. -- **R2.** Source list `[A, null, B]` preprocesses to `[A, {$empty: true}, B]`, not `[A, B]`. -- **R3.** Source list `[A, {}, B]` preprocesses to `[A, {$empty: true}, B]`, not `[A, B]`. -- **R4.** Type chains merge according to the overlay and subtyping rules. -- **R5.** Fixed-value invariants cannot be overridden. -- **R6.** Schema constraints accumulate; irreconcilable constraints fail resolution. -- **R7.** Schema objects containing keys outside §9.2 are rejected. -- **R8.** `name` and `description` are ignored by matchers and subtype checks. -- **R9.** Type root `name` and `description` are not inherited onto the instance root. -- **R10.** A Source Document and its Resolved View, after canonicalization, produce the same Content BlueId. -- **R11.** Requirement overlays bind valid type completions and reject conflicting completions. -- **R12.** `$previous` is validated against the resolved inherited prefix; mismatch fails resolution. -- **R13.** `mergePolicy` defaults to `positional` only when there is no inherited effective `mergePolicy`. -- **R14.** Append-only lists reject `$pos`. -- **R15.** Positional lists reject inherited-prefix reordering and removal. -- **R16.** A Minimized Overlay re-resolves to the same Resolved View. -- **R17.** Canonical Identity Input does not contain `$previous`, `$pos`, `blue`, unresolved aliases, `null` list elements, or empty-object list elements. -- **R18.** Direct hashing of a Resolved View is not used as Content BlueId unless the Resolved View is already identical to its Canonical Identity Input. -- **R19.** Canonical Identity Input for append-only lists does not serialize `$previous`;

Worked Examples - -BlueIds ending in `...` in this section are illustrative placeholders, not conformance vectors. Exact expected BlueIds are defined by the machine-readable fixture suite (§16.4). - -### 17.1 Content-addressable types (informative) - -```yaml -name: Simple Amount -amount: - type: Double -currency: - type: Text -# => blueId: FgHZjS... - -name: Person -age: - type: Integer -spent: - type: - blueId: FgHZjS... # Simple Amount -# => blueId: GRwTYs... -``` - -Instance: - -```yaml -name: Alice -type: - blueId: GRwTYs... # Person -age: 25 -spent: - amount: 27.15 - currency: USD -# => Content BlueId: 3JTd8s... -``` - -Expanding the type chain produces an Expanded View. Resolving produces a Resolved View. Canonicalizing the Resolved View produces a Canonical Identity Input whose Node BlueId is the Content BlueId of the instance. - -### 17.2 `blue` directive (informative) - -```yaml -blue: - imports: - Person: - blueId: GRwTYs... -name: Alice -type: Person -age: 25 -``` - -Preprocessing replaces `Person` with its BlueId reference, infers primitive scalar types, and removes `blue` before hashing. - -### 17.3 Large integer (informative) - -```yaml -accountId: - type: Integer - value: "9007199254740992" -``` - -The value is quoted because it is outside the safe JSON numeric integer range. The explicit `Integer` type distinguishes it from Text. - -Numeric token inference: - -```yaml -a: 1 # inferred Integer -b: 1.0 # inferred Double -c: 1e0 # inferred Double -d: - type: Double - value: 1 -``` - -`b`, `c`, and `d` are Double values even when their canonical JSON number renders as `1`. - -### 17.4 Same image, different meaning (informative) - -```yaml -# A -name: Person to Avoid -description: This guy will kill you today -type: Image -image: - blueId: 123...456 - -# B -name: Family Member -description: Trust this person -type: Image -image: - blueId: 123...456 -``` - -These have different Content BlueIds because `name` and `description` are identity content. Structural and type matchers ignore those labels. - -### 17.5 Requirement overlay followed by type binding (informative) - -```yaml -# Parent -name: A -prop1: - x: 1 - -# Child -name: B -type: A -prop1: - type: Some -``` - -The child is valid only if `Some` can resolve while preserving `x = 1`. If `Some` forces `x = 2`, resolution fails. - -### 17.6 Lists: refine and append (informative) - -```yaml -# Parent -name: Trip -segments: - type: List - itemType: Flight Segment - items: - - type: Flight Segment - carrier: BA - -# Child -name: Trip LHR to SFO -type: Trip -segments: - items: - - $pos: 0 - from: LHR - to: JFK - - type: Flight Segment - carrier: BA - from: JFK - to: SFO -``` - -The child refines inherited index `0` and appends a second segment. Reordering or deleting the inherited prefix would be invalid. - -### 17.7 Null list element as placeholder (informative) - -```yaml -items: - - A - - null - - B -``` - -preprocesses to: - -```yaml -items: - - A - - $empty: true - - B -``` - -It does not preprocess to `[A, B]`. - -### 17.8 Expansion with limits (informative) - -Starting from: - -```yaml -blueId: 3JTd8s... # Alice -``` - -expanding `/spent` may hydrate only the `spent` subtree: - -```yaml -name: Alice -type: - blueId: GRwTYs... -age: 25 -spent: - amount: 27.15 - currency: USD -``` - -Node BlueId is unchanged if the hydrated content verifies to the referenced BlueIds. - -### 17.9 Canonicalization (informative) - -From a Resolved View with fully materialized type subtrees, canonicalization: - -- collapses type objects to `{ blueId: ... }` when available; -- removes structure derivable from the type chain; -- consumes `$pos` overlays; -- normalizes list placeholders to `$empty: true`; -- keeps instance contributions; -- produces valid BlueId Input. - -The Canonical Identity Input yields the Content BlueId. A Minimized Overlay, when produced, re-resolves to the same Resolved View through ordinary Source overlay semantics. - -### 17.10 Contracts merge as content (informative) - -```yaml -# Parent type -name: With Audit -contracts: - audit: - type: Audit Contract - enabled: true - -# Child instance -type: With Audit -contracts: - audit: - retentionDays: 30 -``` - -Language resolution merges `contracts.audit` as content. It does not execute the contract. The resolved contract entry contains both `enabled: true` and `retentionDays: 30`, unless normal fixed-value, type, or schema rules reject the merge. - -### 17.11 Common invalid forms (informative) - -Mixed reference and content is invalid: - -```yaml -blueId: X -name: Not allowed -``` - -`blue` is root-only and preprocessing-only: - -```yaml -child: - blue: something -``` - -`$pos` cannot appear in Canonical Identity Input or BlueId Input: - -```yaml -items: - - $pos: 0 - value: A -``` - -Use `$replace` for non-scalar positional replacement: - -```yaml -# Invalid -- $pos: 0 - value: - items: [A, B] - -# Valid -- $pos: 0 - $replace: - items: [A, B] -``` - ---- - -## Appendix A — Core Primitive and Collection Types - -Appendix A defines the canonical primitive and collection types referenced throughout this specification. - -The nodes in §A.1 are canonical type definitions, not illustrative sketches. Their `description` fields are normative, identity-bearing Blue content. The exact registry files used to calculate published BlueIds MUST be byte/string equivalent after Blue parsing to the intended canonical nodes. - -Changing a canonical node's `description` is a type-identity change. Implementations MUST NOT silently update canonical descriptions while keeping the old BlueId. - -If a typo or editorial issue is found after publication and it does not change semantics, publish errata outside the canonical node. If the text change is intended to alter or clarify the type's meaning in an identity-bearing way, publish a new registry entry with a new BlueId. - -### A.1 Canonical core type nodes - -#### Text - -```yaml -name: Text -description: > - Core Blue Language 1.0 primitive scalar representing Unicode text. Text - values are exact Unicode code-point sequences after parsing. Blue Language - performs no Unicode normalization, case folding, locale-sensitive collation, - whitespace normalization, or line-ending normalization by default. String - schema constraints minLength and maxLength count Unicode code points. The - empty string is valid unless restricted by schema. Applicable schema - constraints are minLength, maxLength, and enum. -``` - -#### Integer - -```yaml -name: Integer -description: > - Core Blue Language 1.0 primitive scalar for exact mathematical integer - values. Integer values are arbitrary precision in the language model. - Unquoted integer tokens are portable only in the safe JSON numeric integer - range [-9007199254740991, 9007199254740991]. Integer values outside that - range are represented as quoted canonical decimal text with explicit or - inherited effective Integer type. The canonical decimal text form uses an - optional leading minus sign followed by decimal digits, with no leading - zeros except the single digit zero. Applicable schema constraints are - minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, and enum. -``` - -#### Double - -```yaml -name: Double -description: > - Core Blue Language 1.0 primitive scalar for finite IEEE 754 binary64 - floating-point values. NaN, positive Infinity, and negative Infinity are - invalid Blue values. Double parsing uses round-to-nearest, ties-to-even - binary64 semantics; numeric tokens that overflow to Infinity or parse as NaN - are invalid. Source numeric tokens with a decimal point or exponent infer - Double when no explicit type is provided, even when their mathematical value - is integral. Negative zero and positive zero compare as the same numeric - value and canonicalize as JSON number zero, while the effective Double type - remains part of canonical BlueId input. Applicable schema constraints are - minimum, maximum, exclusiveMinimum, exclusiveMaximum, multipleOf, and enum. -``` - -#### Boolean - -```yaml -name: Boolean -description: > - Core Blue Language 1.0 primitive scalar with exactly two values: true and - false. Blue Language defines no truthiness conversion for Boolean values. - Only the literal parsed boolean values true and false are Boolean values. - Applicable schema constraint is enum. -``` - -#### Dictionary - -```yaml -name: Dictionary -description: > - Core Blue Language 1.0 object-map collection type. A Dictionary is encoded - as a Blue object node whose ordinary child fields represent direct keys - when those keys do not collide with reserved language fields. Direct object - encoding cannot represent data keys named name, description, type, itemType, - keyType, valueType, value, items, blueId, blue, schema, mergePolicy, - contracts, properties, or constraints. Direct object encoding cannot - represent reserved language keys as data keys. Applications needing - arbitrary keys use an application-defined escaped representation. keyType is optional; if - omitted and no effective keyType is inherited, keys default to Text for - direct object encoding. For direct object encoding, keyType must resolve to - a scalar key type with a canonical textual form, such as Text, Integer, - Double, or Boolean. valueType is optional; if omitted and no effective - valueType is inherited, values may be any Blue node. Applicable schema - constraints are minFields and maxFields. -``` - -#### List - -```yaml -name: List -description: > - Core Blue Language 1.0 ordered collection type. Surface array form and - wrapped items form are equivalent authoring forms. Order and multiplicity - are preserved. List BlueId calculation uses a domain-separated streaming - fold over element BlueIds. itemType is optional; if omitted and no effective - itemType is inherited, elements are not constrained by itemType. If - mergePolicy is omitted and no effective mergePolicy is inherited, resolvers - assume positional. append-only forbids changes to the inherited prefix. - positional allows $pos overlays within the inherited prefix. $previous, - $pos, $replace, and $empty are recognized only at the top level of items - when the node's effective type is List. Source list null and empty object - elements normalize to $empty: true and are not deleted. Applicable schema - constraints are minItems, maxItems, and uniqueItems. -``` - -### A.2 Editorial and registry rules - -The canonical registry nodes above are part of the Blue Language 1.0 type identity. Non-normative examples, tutorials, rationale, translations, and implementation notes are not part of the canonical type nodes unless intentionally included in the registry entries. - -Additional explanatory documentation MAY follow this appendix or appear in separate registry documentation, but it MUST be clearly marked non-canonical unless it is included in the registry node itself. - ---- - -## Appendix B — Reserved Extension Boundary - -`contracts` is reserved for the Blue Contracts and Processor Specification. Blue Language 1.0 treats it as identity-bearing content only. See §4.4. - ---- - -## Appendix C — Common Implementer Mistakes - -This appendix is informative. - -### C.1 Do not delete list positions - -`[A, null, B]` does not mean `[A, B]`. Source list `null` and `{}` elements normalize to `$empty: true`. - -### C.2 Do not hash `blue` - -`blue` is a preprocessing directive. Direct BlueId input containing `blue` must be rejected. - -### C.3 Do not treat `value` as a generic replacement field - -`value` is the scalar payload wrapper. Positional non-scalar replacement uses `$replace`. - -### C.4 Do not let `$pos` reach BlueId input - -`$pos` is an overlay instruction. Canonical Identity Input and direct BlueId Input must not contain `$pos`. - -### C.5 Do not trust provider content without verification - -When expanding `blueId: X` through an ordinary BlueId provider, compute the returned content's Node BlueId and verify that it equals `X`. - -### C.6 Do not treat `name` and `description` as comments - -They affect BlueId. They are ignored by matchers, not by identity. - -### C.7 Use only the schema keywords defined in §9 - -A `schema` object accepts only the keywords listed in §9.2. - -### C.8 Do not use reserved language keys as ordinary object fields - -Reserved keys such as `type`, `value`, `items`, and `schema` have language meaning. - ---- - -## Appendix D — Error Categories - -This appendix is normative for conformance diagnostics but does not require a particular exception class, wire format, or exact error message. - -When an operation fails deterministically, implementations MUST be able to classify the failure into one of these categories for conformance reporting: - -| Category | Meaning | -|---|---| -| `InvalidSyntax` | Serialized JSON/YAML is malformed or outside the Blue JSON data model. | -| `DuplicateKey` | A serialized object contains duplicate keys. | -| `InvalidReservedField` | A reserved field has an invalid type, shape, or position. | -| `InvalidBlueId` | A BlueId string is malformed or invalid for its context. | -| `InvalidReferenceShape` | `blueId` appears with sibling fields or invalid mixed reference shape. | -| `InvalidBlueIdInput` | Direct Node BlueId received a node that is not valid BlueId Input. | -| `ProviderUnavailable` | Required provider content is unavailable. | -| `ProviderBlueIdMismatch` | Provider content does not verify against the requested BlueId. | -| `TypeCycle` | Resolution detected a type-cycle in the active type stack. | -| `FixedValueConflict` | A descendant attempted to override or contradict an inherited fixed value. | -| `TypeCompatibilityViolation` | A descendant type, itemType, keyType, or valueType is incompatible with an inherited constraint. | -| `SchemaVocabularyError` | A schema contains an unknown keyword or invalid schema value shape. | -| `SchemaViolation` | A node violates accumulated schema constraints. | -| `ListControlViolation` | `$previous`, `$pos`, `$replace`, or `$empty` has invalid shape or context. | -| `CanonicalizationError` | A Canonical Identity Input cannot be produced deterministically. | -| `CircularSetError` | Cyclic-set input is malformed or cannot produce deterministic member IDs. | -| `UnsupportedPreprocessingTransform` | A Source Document requires a preprocessing transform that is unsupported. | - -An invalid document may contain multiple independent errors. Blue Language 1.0 does not require a universal precedence order for all possible simultaneous failures. Conformance fixtures that assert an exact error category MUST isolate one primary error so that a conforming implementation can deterministically report that category without ambiguity. If a fixture intentionally contains multiple independent errors, it MUST assert only that the operation fails, or it MUST explicitly declare acceptable error categories. - ---- - -*End of Blue
