Wave 0 for the Cypher→mask lowering: 37.3 % of the corpus lowers fully, 0 % fails to lower, and the binding it needs already ships unconsumed - #1240
Merged
Conversation
The translation matrix's §6 recorded that the 22-TU .cpp harvest yielded seven TUs at 100% Empty, because DuckDB's execution is template-dispatched and lives in headers. A header pass was run on 2026-09-14 and its counts written into the README — but that file's own honesty note says the complaint was NOT discharged: the TSVs, the args and the DuckDB source were all absent, so what existed was "a README quoting counts from a TSV that is absent." Now committed beside it: run.sh (one command), headers.txt, args.txt.in (a template, so include paths follow DUCKDB_SRC instead of being pinned to one machine), the 40 TSVs at 348K, and provenance.txt carrying the DuckDB commit, origin, ruff commit and clang version. Source is the AdaWorldAPI fork per P0; upstream duckdb/duckdb is out of scope and returns 403. Methods re-derive to 123 — an exact match with the recorded table on all ten rows, so that observation is confirmed rather than quoted. Events land at 1620 against 1622, differing on four rows (+1, -5, +1, +1). Methods matching exactly means no method was added or removed, so the deltas are inside bodies — source drift between two checkouts. The earlier run recorded no commit, so there is nothing to diff against, and that is exactly the gap provenance.txt closes. Recorded because it nearly went the other way: the first run.sh subtracted a header row from each TSV and reported 115/1612, a clean uniform -1 on every non-empty header, which reads as "the earlier numbers were inflated." Neither TSV has a header row; line 1 is already data. What caught it was the shape of the disagreement — uniform -1 with 0 on the two empty headers is an off-by-one, not source drift. A measurement harness is code and earns the same scepticism as what it measures. Also names what is still unrun: harvest_events is the BEHAVIOURAL arm. The STRUCTURAL arm (extract_tree -> ModelGraph, has_function / inherits_from / virtually_overrides, feeding ruff_spo_triplet and ruff_cpp_codegen) has never been pointed at DuckDB.

Operator endgame. The survey's point is that this is a wiring job, not a design job: extract_tree -> ruff_spo_address::mint (16B, byte-identical to FacetCascade, no dependency edge) -> ogar-from-ruff::mint -> lance_sink -> as_le_bytes() is all live, unstubbed code, stopping at a Dataset::write that lance_sink.rs names out of scope in its own words. That write is G-C. The direction is forced, not chosen: no ruff crate may compile against lance-graph — verified, "lance.graph" appears in ruff/crates/*/Cargo.toml only inside two description strings. So the spine can only be the HOME, fed across a byte boundary. Confirms two operator recollections, corrects one, adds a third arm. Codegen arms are ruff_cpp_codegen (Rust MethodSig source), ruff_spo_address (the part_of:is_a rank-mint) and — found after the operator named it — ruff_python_dto_check::codegen (handler + view template, kind-generalized by KindRecipe, with a jinja leg). NOT ruff_python_codegen, which is upstream ruff's Generator/Stylist. JSONML exists nowhere in the five repos. arm-discovery is the table->SPO arm exactly as described and already names ruff_spo_triplet::Triple as its downstream. Records why the OLD ModelGraph's SurrealQL AST DLL sink was wrong, because it names this plan's own risk: deprecated 2026-07-22 as "a separation-of-concerns error", the behavioural arm having no DDL vocabulary so it had to hijack DEFINE EVENT. The corrected shape is a wrapper wiring three legs — adapters, storage, Klickwege-parity askama — and G-C is only the storage leg. An implementation reaching into the other two would be the same mistake at a new target. The same trap in Java clothes is sql() becoming where behaviour lives, which the lance-graph-java ruling already forbids from the other side. G-E is the uncomfortable one and independent of all this: quack has no DuckDB in its loop at all, so what is called parity today is quack against its own hand-written oracle.

…t an actor Operator correction: ractor is replaced by the SoA mailbox, and the supervisor's kanban_actor.rs is the read-only monitoring remnant. Confirmed in source, and it removes an imaginary blocker from the plan. lance_sink.rs says the column write "needs the lance engine / ractor runtime". The ractor half is out of date. kanban_actor.rs's own tombstone (2026-08-05, E-PROGRESSION-IS-EXISTENCE-NOT-COMMAND-1) says KanbanActor, KanbanMsg and the RPC drivers are "DELETED, not deprecated: a version tick was being read as permission to advance, and an ack-shaped RPC was being read as what makes the substrate progress." The model that replaced them is think -> seal -> publish Lance version -> next cycle reads it, and "nothing signals, acknowledges, or schedules that." The write discipline is in cognitive-shader-driver/src/mailbox_soa.rs — the operator's "soa_mailbox.rs" with the words swapped, which is why this was worth checking rather than restating; searching that filename finds nothing. It carries one-writer-per-mailbox as a compile-time property: rows consumed in place by the owner, no emission, ownership compile-proven. So G-C changes from "adopt an actor runtime we lack" to "publish a Lance version from an owned mailbox", and W3 gains a sharp falsifier: an implementation that introduces a message, an ack, a tick or a per-owner advance() RPC has re-created the deleted shape and fails on that ground whether or not the bytes land. lance-graph-java already carries this as an inherited rule; it applies with more force in the repo that did the deleting. Records the ractor residue (four Cargo.toml entries, two optional, symbiont operator-ruled no-go) so it is not read as the live model.

…pine Operator named five loose ends. Surveyed, and four of them turn out to be built ends that do not meet rather than things to build. BatchWriter (#879, #908-912, #949): #912 landed the sole owned Lance writer, so Dataset::write is real at cycle_sink.rs:675/710 and this plan's own "no Dataset::write" was wrong when written. batch_writer.rs's status note claiming cast() has zero production call sites is stale too — three today, all production: mailbox_soa (the owner), owner_adapter (write-on-behalf), cycle_driver (P4a drain). The other ~17 .cast( hits are ractor ActorRef::cast and would have inflated the count. What IS unwired is the observation leg: deinterlace has zero production callers, every hit a doc comment. So G-C splits — G-C1 connect OGAR's bytes to the writer that already exists, G-C2 wire the durability read. A write nothing reads back is not yet a loop. revision.rs is Heckhausen's last phase (postactional evaluation), and that makes it the same gap seen from the other end: the court of appeal has no write-back because the durable read that would tell it what happened is missing. The Rubicon model is genuinely wired otherwise — five phases in cognitive-compiler, rubicon_witness.rs, D-ACR-8. The kanban seam is NOT unwired: lance-graph-ogar is a workspace member depending on both sides by design, and recipe_vocab.rs already carries the 34 NARS recipes as ogar-loco ops with the kanban census as the awareness surface. The palette arc's constraint is that it must not ride the deprecated substrate the recent PRs surfaced — Binary16K and the singleton BindSpace are superseded, and temporal.rs's version-range read is what replaced them, which lands on G-C2 again. And the remediation is hot-plug, not a Cargo edge: socket in the zero-dep contract, authority production at lance-graph-ogar lib.rs:524, consumer declares one HotPlug const and activates. The classid is the join key — plug and play mints the classid, the classid mints ogar-vocab, which triggers the loco vocabulary. All eight existing declarations are test fixtures and the planner has none. Three claims in this document were drafted false and corrected before commit by re-checking citations. Recorded, including that a fully qualified impl made a negative grep read as "unimplemented" — a negative grep is a claim about the pattern, not about the tree.

Operator rule. It names the exact failure this session produced three times in one document, each caught before commit only because a later read contradicted the earlier grep: - "planner has no dependency edge to loco" — lance-graph-ogar is a workspace member depending on both sides; its Cargo.toml says so. - "CapabilityAuthority is unimplemented" — it is implemented and production, written fully-qualified, so the pattern missed it. - "the kanban seam is unwired both directions" — the grep was CORRECT and the conclusion still wrong, because recipe_vocab.rs's module doc explains the design and was never opened. That third one is the instructive case: a correct grep can support a false conclusion. Absence under one pattern is not absence in the tree. Also records the counting half: the same session nearly reported 20 BatchWriter::cast sites when reading showed ~17 were ractor's unrelated ActorRef::cast and only 3 were real. Placed beside Read-before-Write, which protects files from a blind write; this protects conclusions from a blind read.

… moat Read the crate rather than grepping it. The architecture is already emancipated; what has not moved is the identity. Its own lib.rs argues the point — blockly-rs "proved a storage shape" and this crate "generalizes it", with elixir templates and Power-Automate flows named as consumers two and three. Blockly is consumer #1 of three, not the purpose. vocabulary.rs does the emancipating and enforces it: below DOMAIN_FLOOR is the shared computational core whose arities live once, so IF cannot mean two things in two domains; at or above the floor belongs to the vocabulary; a core byte the core does not cover is refused everywhere rather than guessed. conformance::check is the gate, in the JVM-verifier / Wasm-validator posture — validate before trusting, refuse loudly. So emancipate does not mean become less boring. The Scratch-shaped floor is load-bearing: a drifting core is N dialects. Emancipation is upward, and it has already started — recipe_vocab carries the 34 NARS recipes as loco ops above the floor, in the same two-byte (function : value) call as repeat, with no ABI change. That is the vocabulary-agnostic claim cashed. Records that this is the Java ruling one tier down. Both surfaces are deliberately dumb, both resolve meaning through the classid, and in both the temptation is to make the surface cleverer. A loco emancipation that grew core opcodes, or let a vocabulary redefine a shared-core byte, would be Mask.minus() in block clothing. The Java ruling is already written down; it should be read as covering loco too. Consequence for G-F: the planner's missing HotPlug is how a kanban vocabulary gets to exist above the floor without anyone importing anyone. Plug and play mints the classid, the classid mints ogar-vocab, which triggers the loco vocabulary — the cascade IS the emancipation mechanism.

Third correction, and it retires a blocker I invented. I wrote that "a write nothing reads back is not yet a loop". Reading batch_writer.rs shows both halves of the operator's "fire and forget write + try progress kanban" already in its module doc: the sink drains eagerly, "the thinker reports (casts) and moves on — melden macht frei — it is NEVER refused", and collect_casts seals one paired_move per owner which recover_and_apply applies via try_advance_phase, consulting no scheduler. So the loop closes on cast + try-advance, not on a read-back. deinterlace belongs to the observation arm and gates neither the write nor the advance. The kanban IS the Rubicon DAG rather than a separate subsystem: try_advance_phase returns Result<KanbanMove, RubiconTransitionError> and its body is from.can_transition_to(to). revision.rs is already bound to it contractually and by test — "whatever revise proposes must be an edge try_advance_phase accepts; it completes the Rubicon DAG, it does not route around it." Measured, the chain is wired at both ends and hollow in the middle: cast has 3 production callers, try_advance_phase 1, and recover_and_apply ZERO — its only two call sites sit inside mod tests. So G-C2 is a connect, not a build. Records the planner as the hot-plug home and what that unlocks: sql() becomes one classid in a loco vocabulary rather than a bespoke Java surface, and the same activation brings the whole DuckDB vocabulary with it. That reframes today's reproducible harvest — it is vocabulary source, not documentation of a competitor, which is what "always use ruff cpp to analyze the duckdb code" was for. Also notes the planner's DataFusion leg has both a standing ruling and a worked example (quack's lowering, pinned equal to plan_lower) to migrate onto. Wave order revised: extract_tree, then the planner's HotPlug const as the smallest change with the largest unlock, then connect recover_and_apply, then the DataFusion replacement, with the DuckDB differential still independent.

…lready bounded
Closes the arc the harvest opened. The assessment exists: matrix row A3
reads JoinHashTable's probe path and rules it V3-better for the addressed
case, because ht_entry_t's 16-bit salt is a probabilistic prefix derived
from a hash while the V3 classid prefix is a contiguous row range
(49-99 ns vs 22.4 us). DuckDB independently arrived at zero-is-absence,
the same convention as the zero-fallback ladder.
Fed from loco rather than ported: a join is a (function : value) call
like any other, so the vocabulary names it, the classid selects it, and
the existing lowering carries it to the one mask-risc evaluator — the
same path quack already proves for scan/filter/project/group. The minted
case collapses to a prefix range; only the unminted case needs hash
machinery.
Scope is bounded by two caveats derived independently and agreeing: A3's
own ("holds only when both sides are minted into the same address space")
and the queued PR5's ("no replacement claim for bag or cross-address-space
joins"). A3 also flags that its row reads two functions, not the join —
spilling, radix partitioning and chain building are unassessed.
Final wave order: extract_tree, the planner's HotPlug, connect
recover_and_apply, the DataFusion replacement, then the join leg, with
the DuckDB differential independent throughout. The join is last of the
build waves because it needs both the vocabulary and the harvest.

Fourth correction of the session, and the target is not where it looks. lance-graph-planner has NO DataFusion dependency and no DataFusion code. All ten mentions across 10,028 LOC are doc comments crediting a pattern — RuleOptimizer "from DataFusion", ExtensionPlanner "from DataFusion's UserDefinedLogicalNode pattern", the optimizer "inspired by DataFusion's OptimizerRule trait", broadcast "analogous to DataFusion's Repartition". The `datafusion = []` line is a FEATURE, under [features] beside jit = [], and it is inert: nothing is cfg-gated on it and no manifest in the workspace enables it. Removed, with the reason inline — its only live effect was making every grep of the Cargo manifests misreport this crate as a DataFusion consumer. My own census script fell for exactly that, one turn after I added the rule forbidding it. Tests green: 435 passed, 0 failed, 2 ignored. The real surface is 8,044 LOC in lance-graph/src/datafusion_planner/ — the core crate. So reviving the planner as the center of gravity is a migration inward, not a deletion: move that capability in as masked-op lowerings, with quack as the worked example and plan_lower == quack::lower already pinned by a differential. The planner is already structurally central to the write path — cognitive-shader-driver depends on it, and batch_writer, owner_adapter and persist_sink all live there — so what is missing is the query side rejoining the write side. Records the intake reroute: parser.rs is 1,932 LOC of nom Cypher over a 544-line AST, and what it must stop feeding is semiring_map's HDR semirings over 16Kbit BitVec matrices — the substrate the recent PRs found deprecated. The parser stays; that leg is what the masked path replaces. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X6y3drwKSE2zSgoexheLFX
…undary Censused the fork against upstream's tree: ~18,400 LOC inherited, of which datafusion_planner/ is 8,044 — 44% of the surface. Two divergences named: upstream's csr_index.rs is absent here (this fork went its own way with the planner's Kuzu-style adjacency), and our additions are soa_config.rs, reasoning.rs, dev_s3_env.rs. The seam is stated by the backend itself: datafusion_planner/mod.rs says it "translates graph logical plans into DataFusion logical plans" and maps "Nodes -> Table scans, Relationships -> Linking tables, Traversals -> Joins". So logical_plan.rs is the boundary, and the migration does not touch the vocabulary above it — parser, ast, semantic and logical_plan are 5,612 LOC that stay. "Traversals -> Joins" is precisely the inherited SQL join to replace, and its masked counterpart is already queued as task #10 / PR5: src_mask -> hop -> dst_mask versus the node-edge-node join. Two halves specified independently, meeting at this seam. Variable-length paths are not an obstacle — upstream unrolls *1..3 into fixed plans plus a UNION, which in mask terms is N hops OR'd, a MaskOp composition. This also answers the semiring-json reroute in the same move: the graph-side leg (semiring_map over 16Kbit BitVec, deprecated) and the SQL-side leg (datafusion_planner) are two backends under one vocabulary. One seam, two legs retired, one replacement. Migration order within W-DF: scan_ops, predicate_pushdown, expression, projection/aggregate, then join_ops last. vector_ops and lance_vector_search are explicitly out of scope — the Lance ANN path is not a DataFusion artifact and no masked equivalent is claimed for it.

… fork Measured before writing a lowering. lance-graph core depends on lance-graph-planner (optional, behind the planner feature, plus a dev-dep); the reverse edge does not exist and would be a cycle. Only quack depends on mask-risc. So the planner cannot hold a logical_plan -> Program lowering today: the plan lives in core, reaching it is a cycle, and a planner-local copy would be the parallel-IR anti-pattern the arc exists to avoid. Two facts make that position honest rather than awkward: the planner's own Cypher/GQL/Gremlin/SPARQL strategies are regex stubs — this repo's open list already says "wire planner strategies to lance-graph core (actual parser, not regex)" — and the real 1,932-LOC nom parser is in core. The planner is genuinely downstream of the vocabulary. Three routes recorded: the lowering in core (smallest, but leaves the query side there permanently), the plan vocabulary moved down into the zero-dep contract (largest, and what actually makes the planner central), or a bridge crate depending on both. The third is established precedent — lance-graph-ogar exists for exactly this "neither may import the other" shape and says so in its module doc. Left as an operator call because the routes produce materially different repos and neither reverses cheaply. Everything else is settled either way: the seam is logical_plan.rs by the backend's own description, the 5,612-LOC vocabulary above it is kept, the 8,044-LOC DataFusion backend and the semiring_map/16Kbit leg are the two legs retired, and quack is the worked shape.

The plan's own STOP gate, answered with a number instead of an opinion.
`cypher-mask-lowering-v1.md` §7.0 says nothing is built until Wave 0
measures, and `mask_lower` exists nowhere in the tree — so the boring
correct move was to measure, not to write a lowering.
62 literals extracted (40 parser.rs + 22 logical_plan.rs, 0 semantic.rs)
50 classified -> 23 Full (46.0%) / 27 Split (54.0%) / 0 Grace (0.0%)
§7.0's STOP condition does not fire: "negligible" it is not.
The corpus is `include_str!`-ed out of the committed sources and
classified through the REAL parser + LogicalPlanner, so it cannot drift
from the tests it mirrors, and every disposition cites the §3/§4 row
that rules it. All 40 grace hits land in §4.6's table — 17 on strings
and non-integer literals, 17 on order and position, nothing else above
two — which is the check that the classifier reads the plan rather than
inventing a boundary.
Two findings the percentages do not contain:
1. 9 of the 10 plan-REFUSALS return a bare node variable — measured by
inspecting the AST the planner refused, not by eye. `RETURN <node>`
is §3.5 T-3, `Terminal::Keep`, "the mask itself": the cheapest thing
the mask path can do. The incumbent planner refuses it, and because a
refusal is excluded from the denominator, 46.0% understates the
premise by exactly the shape that most favours it.
2. The extractor was wrong once and the bug moved the headline 29
points. `parser.rs:931-933` has `char('"')` three times; a scanner
that does not know about char literals opens a string there and runs
one quote out of phase for the rest of the file. First run: 15 of 20,
75.0%. Both runs exited 0. What caught it was ENUMERATING the
exclusion buckets rather than counting them — "3 did not parse" is
unfalsifiable; printing them showed raw Rust source on line one.
Also records §14: the A/B/C placement fork §13 left open does not
exist. `cypher-mask-lowering-v1.md` §5.2 ruled it months ago — Boolean
combination CONSUMES the already-minted TERNLOG 0x86 (zero consumers
today, so it is a net reduction in unconsumed surface); Pred/hop/
terminals are a lowering target that must never be minted, by the test
"does a BYTE of this survive the query that produced it?"; and the
trigger that would flip that is a stored artifact, whose home is
already settled by `recipe_vocab.rs`'s precedent. Same failure the
grep-FINDS-reading-DECIDES rule names, one level up: the dependency
graph was measured correctly and a fork inferred from it, without
reading the plan that had already closed it.
§14 also answers the mindset question with what enforces it rather than
with agreement: a `Program` has no spelling for an owner, a phase or a
move, so a consumer holding the glove cannot express a kanban
transition even if it wanted to; and mask-risc is the convergence point
both core and the planner can depend on without a cycle, which is the
p64 shape reused rather than a new one invented.

…ro consumers
§7.0's hardest STOP condition — "no label->classid route AND no cheap one
can be minted" — does not fire, and the reason is a type that already
ships.
`lance-graph-contract::ogar_codebook::LabelDTO` is `{ label, id,
canonical }`, doc-commented as "identity comparison uses `id`; AST/planner
emission uses `canonical`", with `id` documented as "the classid low u16".
`LabelDTO::from_canonical` resolves it. `mailbox_scan::match_nodes_by_class`
already takes exactly that u16 at the far end.
Consumers across the workspace: ZERO — the only hit outside its own module
is its re-export in lib.rs. Same shape as TERNLOG 0x86: a minted, exported,
unconsumed surface the lowering would CONSUME rather than duplicate. Two of
this plan's "gaps" are now the same kind of thing — built ends that do not
meet.
What is missing is a FIELD, not a mechanism: `NodeMapping` is `{ label,
id_field, property_fields, filter_conditions }` with nowhere to carry a
canonical concept. One field wires a binding that already exists; no new
codebook, no vocabulary, no byte minted, so §14.0 Part 2's test is
untouched.
The honest caveat, and it changes how §15's 46% reads: the corpus's labels
are NOT in the codebook. Measured against its 123 entries — `Person` no,
`Company` no, `Thing` no, `Node` no (osm_node and mars_node_template are
different concepts). The codebook carries real domain concepts (project
0x0101, billing_party 0x0204, osm_node 0x0F01); the Cypher test labels are
synthetic and were never minted, which is what a parser test corpus is.
So 46% is a measurement of SHAPE, exactly as §15's own caveat 1 says, and
a production number needs a real bake — the rest of W0-a, still unrun.

CI red on #1240, one new decay, reproduced locally byte-for-byte before touching anything: DECAYED .claude/plans/lance-graph-as-the-modelgraph-v1.md:324 -> crates/lance-graph/src/graph/cycle_sink.rs:675 anchor=symbol:":710" (anchor absent within +-3 lines) The citation read ``…cycle_sink.rs:675`` followed by a bare `` `:710` `` as shorthand for the second call site. `extract_anchor` takes the NEAREST backticked token as the thing to go looking for at the cited line, so it adopted `:710` — which is not a symbol and appears nowhere near line 675. The gate's own message says the fix is not a corrected number, and it is right: both sites are real (`Dataset::write` is literally on 675 and on 710). What was wrong is the SHAPE. Each citation now carries `Dataset::write` adjacent to it, which is the string actually present on both cited lines, and names its enclosing function (`LanceCycleWriter::bootstrap` / `::raw_append`) for a reader. Generalizable, and recorded inline as a ⊘ note rather than silently fixed: a shorthand second reference is cheap to write and costs a real gate failure, because the anchor is chosen by proximity, not by intent.

… 303 Four P1s from codex on #1240. All four verified by reading before being fixed; three of them moved the number. 1. THE CORPUS WAS A HAND-LISTED SUBSET. The census read three files. A walk of the same tree with the same extractor finds Cypher queries in 27 files — the whole of `crates/lance-graph/tests/`, `src/query.rs`, the planner's strategy modules, the Python bindings. 50 classified -> 303. The defect before the defect: those three files were chosen after a grep for `"…MATCH …"` reported zero hits in the DataFusion builder modules. That grep cannot see a raw string or a literal spanning lines — the same blind spot that made the extractor itself wrong. I used grep as a verdict on the same day I added the rule to CLAUDE.md saying not to. So the fix is structural, not a longer list: the corpus is now a WALK from CARGO_MANIFEST_DIR. A file added to the tree enters the corpus with no edit here, and the run prints how many files it read and which carried a query — scope is now part of the output instead of being invisible. 2. INLINE PATTERN PROPERTIES WERE IGNORED. `MATCH (p:Person {name: "Alice"})` files its predicate in `ScanByLabel.properties` / `Expand.properties` / `.target_properties`, and all four maps went unread, so a string equality that is P-9 grace was counted as a lowered scan. New row: 53 hits. 3. T-12 NEVER FIRED. `DISTINCT n.p` is grace, `DISTINCT n` is free. The `Distinct` arm recursed and left the call to `classify_value`, which accepts a bare `Property` unconditionally — correctly, since T-4 (`RETURN n.prop`) is `[G]`. So nothing ever made the distinction and the histogram had no T-12 row at all, which is what codex noticed. What separates the two is the projection UNDER a `Distinct`, so the `Distinct` node is the only place that can tell them apart. New rows: 37 hits. 4. run.sh SUPPRESSED HARVESTER FAILURES. `|| true` plus an OUT that defaults to the already-committed TSVs meant a failed harvest left the old files in place, `wc` counted them, and the run exited 0 — while provenance.txt had already been rewritten with the CURRENT commits. Old measurements attributed to a new checkout, reported clean. Now the tag dir is removed before each header and a failure exits 4. Corrected measurement: 342 candidates (1451 rust files walked, 27 carrying a query) 303 classified -> 113 Full (37.3%) / 190 Split (62.7%) / 0 Grace (0.0%) STOP still does not fire. And the ordering of the boundary changed, not just the size: order-and-position is now the largest axis at 131, strings and non-integer literals second at 124 — where the three-file census had them tied at 17. A subset misranks a boundary as well as mis-measuring it. The T-3 finding strengthens: 21 of 22 plan-refusals return a bare node variable (was 9 of 10). The planner refuses the query the mask path answers with no work, and refusals sit outside the denominator. Gates: citation-decay --since 31273cb -> 0 new decays; supersession index byte-identical; fmt + clippy clean.

…question withdrawn Decision 1 is not a scheduling tie. The alpha channel is a STORAGE-tier change (multitenant table access) and a query lowering is a read; the write side settles first or the read side is built against an undecided contract. What it buys is simultaneous rungs — the prior state was ten rungs not talking to each other, with "one at a time" as the deprecated alternative, and levels of thinking interact only when their priors sit on the same level. The split tunnel is what lets attention write sparsely without rewriting the ontology. So the Cypher lowering consumes TERNLOG after it, and inherits whatever simultaneity contract it establishes. Decision 3: RevisionKind beside belief.rs. Historically correct home; the wiring is what needs adjusting. Decision 2 is withdrawn rather than answered. I asked for a ruling on a word from a plan the operator did not write, and on a number that had already moved from 46%/50 to 37.3%/303. It was never a decision: 0 of 303 queries fail to lower at all, so the premise covers some of every query in the corpus and no ruling is needed to say that is not negligible. §17.4 records the reporting defect behind all three — reporting in symbol names and section numbers hands the reader ADDRESSES, which only mean something to someone already holding the map. Same defect as citing a line number instead of an anchor, one layer up: it reads as precision and carries none. Plain words first, receipts last.

Supersedes the DIRECTION of 14.2/15/16, not their measurements.
I had Wave 1 of the Cypher plan queued next: a new mask_lower written from
scratch. That is a THIRD lowering onto the same floor. quack already turns a
query into a Program (2260 lines, 14 tests, "may build a Program and must
never evaluate one"), and lgj-abi plan_lower is the second, pinned equal to
quack by a differential so the two cannot drift. A third would be the second
vocabulary both exist to prevent — and I would have been building it while
writing, in this same document, that the recurring finding is two built ends
that do not meet.
The spine today is Query { filter, agg }: filter a population, reduce over
the survivors, every operator a MaskOp, validity a resident plane, a group a
mask. DuckDB shape minus the row iterator and the selection vector.
Its one missing leg is the HOP. Nothing in quack or the IR beneath it can say
src_mask -> edge lane -> dst_mask; mask-risc names it absent and assigns it to
PR5, whose "only after PR1-4 green" gate lifted today. So: the hop lands in
the spine, front-ends lower INTO quack rather than past it, and the DataFusion
residue shrinks by subtraction — one change to quack that every front-end
inherits.
The W0-b census does not go stale; its target changes. It asked how much
Cypher a new lowering could express; it now reads as a work order on the
spine, because the grace rows are properties of masks rather than of any
lowering: 131 order-and-position hits are outside it by construction, 124
string-and-float wait on a variable-width lane, the 28 Join hits ARE the hop,
23 are the vector boundary.

Operator: any graph traversal is a modified version of it, any SPOG query is just another flavor, and the benefit is that nobody ever asks what DuckDB is. Deduplication (three lowerings onto one floor is two too many) is the smaller half. The larger half is that the spine is ALREADY KNOWN: filter, reduce, group, project is a shape every engineer and every model arrives holding. A novel graph IR has to be taught to every reader, every front-end author and every model that touches it. DuckDB shape does not, ever. And neither thing that looks like it needs its own IR does. A traversal is a population narrowing to a population — the hop is a new OPERATOR in a known algebra, not a new algebra. SPOG is four columns; asking for the objects of a subject under a predicate is a filter and a projection. Same test as the Java surface, one tier down: would a reader who has never read our documentation understand this plan from DuckDB habit alone? Boring is load-bearing at both tiers — the surface so a customer needs no manual, the spine so a reader, an author or a model needs none either.

Operator: everything else is running in circles around what is not in your training. That diagnoses a mechanism, not a preference. A private vocabulary is re-derived from documents every time it is reasoned about, and re-derivation is where the circling comes from. This session is the receipt: three stale blockers quoted as current, a placement fork raised as open that had been ruled months earlier, three greps treated as verdicts, a corpus chosen from one of those greps (46% over 50 was really 37.3% over 303), and Wave 1 queued as the next build when it was a third lowering onto one floor. None of those is a hard problem. Each is a lookup that went stale, partial or confidently wrong — because the thing being looked up exists only in this workspace own documents. A filter, an aggregate, a group-by are never looked up. So boring is not a style choice at any tier: it removes the lookup, and removing the lookup removes the circling. Three statements, one read at three depths — a customer should not need a manual, a reader should not need one, and a model should not need one either, because when it does it spends the session re-deriving instead of building.

Inline comments:
In @.claude/plans/lance-graph-as-the-modelgraph-v1.md:
- Line 1407: Update the sentence in Section 15 to use the corrected census
percentage of 37.3% for 113 Full queries out of 303 classified queries,
replacing the superseded 46% figure while preserving the surrounding
explanation.
- Line 556: Update the G-F entry in the planning table to describe the missing
planner-side HotPlug declaration and activate call, replacing the current
“unwired both ways; a build, not a wiring” wording and lowering its severity to
reflect a localized activation gap rather than a major implementation defect.
In `@crates/lance-graph/examples/w0b_corpus_census.rs`:
- Line 68: Update rust_sources and main to propagate I/O failures from
fs::read_dir, directory-entry iteration, and fs::read_to_string instead of
skipping unreadable directories or files. Change the traversal and report flow
to return the encountered I/O error so the census fails rather than producing a
partial successful report.
- Line 435: Update the duplicate-query tracking around seen and per_source so
each query literal retains every source path rather than only the first label.
Preserve literal deduplication for query-level results, but derive per_source
from the complete literal-to-sources mapping so later files contribute to file
counts and per-source statistics.
- Line 153: Update the raw-string detection in string_literals to accept
zero-hash raw literals such as r"..." while preserving hashed forms, and ensure
backslash sequences such as \n, \\, and \' are passed unchanged to
parse_cypher_query rather than unescaped by the ordinary-string path. Add a
focused #[cfg(test)] regression test covering zero-hash raw strings and the
backslash case.

…the finding `regenerate-and-diff` was red at four successive SHAs on #1240 for exactly the reason CLAUDE.md already records from #1085: the supersession index reads the BOARD as an input, so regenerating before the board writes produces a byte-identical file that reads as "already current" while CI, regenerating on the merge commit, sees the rows move. I regenerated first. The rule was right and I ran it backwards. So the entry lands first. E-THE-SPINE-IS-WHATEVER-THE-READER-ALREADY-HAS-AN-ADDRESS-FOR-1 records the operator's quack redirect (the argument is muscle memory, not elegance — a novel IR has to be taught to every reader, author and model, every time), what it cancels (Wave 1 would have been a third lowering onto one floor; the hop is one brick instead), the census correction (3 hand-listed files → a 27-file walk, 46.0%/50 → 37.3%/303, from using a grep as a verdict on the day the rule against it landed), and the three rulings that came with it. It also names the shape the session's four errors share: a grep for the corpus, a section number for the argument, a stale percentage for a decision, a fork raised as open that was already ruled. Each substitutes an ADDRESS for the thing — which is the same insight the redirect states positively. Then the index, regenerated LAST. Coverage closes in two plans, because the entry cites D-MAR-2 where nothing had: modelgraph 5/6 → 6/6, mask-algebra-revision-read 2/3 → 3/3. Gates, all run locally before push: regenerate-and-diff idempotent; append-only +127 EPIPHANIES / +30 INTEGRATION_PLANS, nothing shrank (9 checked); citation-decay 0 new (the entry carries no line-number citations by construction, which is what the gate asks for).

… board entry All five correct. The three code ones all bear on whether the census can be trusted at all, which is the right place for a review to bite. MAJOR — traversal failures were discarded. `rust_sources` returned on an unreadable directory, `flatten()` dropped a failed entry, and `read_to_string` was skipped on error. A run that cannot see part of the tree then reports a clean census over whatever it did read — and §7.0's STOP gate is cleared on that number. Identical in shape to the `|| true` removed from `run.sh` earlier in this PR: a failure that reports success over a partial corpus. Both `rust_sources` and `main` now return `io::Result<()>` and propagate. Zero-hash raw strings. The raw branch required at least one `#`, so `r"..."` fell through to the ordinary-string branch and had its escapes processed — `r"\d+"` arrived as `d+`, a query the tree does not contain. In valid Rust an `r` directly followed by `"` is always a raw string, so the hash count may be zero. Every source per literal. `seen` kept only the FIRST file for each query, and `per_source` — which IS the "files carrying a query" figure — was built from those values, so a file whose every query also appeared elsewhere vanished from the provenance entirely. **Measured after: 27 -> 33 files. The classification does not move** — 342 candidates, 303 classified, 113 Full (37.3 %), 190 Split, 0 Grace, all unchanged. Dedup by literal was always right; only the attribution was not. The uncomfortable part is that the repo already held the right number. The census's own module doc said *33 files* while the program it documents printed *27*, in the same commit, and I quoted whichever was nearer to hand — the doc's 33 into the source, the program's 27 into the plan and into the EPIPHANIES entry written an hour ago. Both are corrected, and the entry now records the failure rather than just the fixed number. Same shape twice more in the docs, both fixed: G-F's summary row said the kanban seam was "unwired both ways" while this document's own body four sections up says socket, authority and the loco landing are all in place and only the planner's `HotPlug` + `activate` are missing; and §15's caveat still quoted the superseded 46 %. A summary row is a second place to be wrong, and it is the place a reader looks first. Three extractor regression tests, and the example is now declared with `test = true` — an example's test flag defaults to false, so `#[cfg(test)]` inside one is compiled and never run. A test that cannot fail where anyone looks is the defect it was written to prevent, and this extractor is what BUILDS the corpus. Paired silent half included: a hashed raw string still spans its embedded quotes and an ordinary string still resolves its escapes, so "treat every string as raw" cannot pass. Index regenerated LAST, after the board write. fmt + clippy -D warnings clean; append-only +15 lines; citation-decay 0 new.

…trap that names it Two things, both earned by actually running the disables rather than trusting 4dabd92's green. **The zero-hash test could not fail under the fix it named.** With the `h > i + 1` bound restored, `a_zero_hash_raw_string_is_extracted` still PASSED — and that is structural, not a bad fixture: for a literal with nothing to escape, the raw branch and the ordinary-string branch emit byte-identical output, so NO such fixture can separate them. Its doc claimed to be the falsifier. Corrected in place, with the disable result in the comment, rather than reworded into something that sounds right. The real falsifier is `a_raw_string_keeps_its_backslashes` (`["d+"]` vs `["\d+"]`), which is now labelled as such; the zero-hash case stays as the weaker guard it actually is — it still catches a raw branch that matches and forgets to push. **The MAJOR finding had no falsifier at all** until now. `an_unreadable_tree_is_ an_error_not_an_empty_corpus` is it: disable-verified by restoring the `let Ok(...) else { return }` swallow, which fails exactly that test and only it. It walks a NONEXISTENT path rather than a chmod-000 one, because this container runs as root and an unreadable-directory fixture would have passed for the wrong reason — measured, not assumed. Paired silent half: the real tree still walks and finds this file. ⊘ And the process failure, recorded because it is the one the workspace already warns about in as many words: *"Commit BEFORE you disable, not after… the restore is `git checkout <file>`, and that reverts to the last COMMIT, not to the state you started from."* I committed before the FIRST disable and then wrote both of the above as UNCOMMITTED edits before running the second — so the `git checkout` that restored the disable deleted them, and they had to be redone from the transcript. Nothing shipped wrong; the cost was real. The order is commit → disable → checkout, every time, and "I already committed once" is not the same as "the work under test is committed".

… after OGAR #304 merged The Mandatory Board-Hygiene Rule's merged-PR pair, plus one finding that only became visible once #304 was on main. **The mandatory pair.** PR_ARC_INVENTORY gains the #1240 entry (merged `e054dcf`): what landed, the final census numbers (303 classified, 113 Full = 37.3 %, 0 Grace), the operator's quack-as-spine redirect that CANCELS the wave the census was gating rather than scheduling it, the nine review findings over two rounds, and the two disable-run results the green tests could not have produced. LATEST_STATE gains the merged entry, with the contract-inventory delta stated as NONE and VERIFIED — `git diff 31273cb..84c7ebe` touches zero files under `crates/lance-graph-contract`, so that line is a measurement rather than the usual assumption. **The finding.** ISSUES gains `ISS-THE-34-RECIPE-LOCO-VOCABULARY-EXISTS-TWICE-AND-THE-TWO-DISAGREE`. `ogar-loco::nars` (OGAR #304) and `lance-graph-ogar::recipe_vocab` both map the 34 recipes to `DOMAIN_FLOOR + id - 1` and both `impl Vocabulary` over that range — and they answer differently: `stack_arity` 2-for-Datapath vs 1-for-all, and a declared `CB_ATTENTION_FOCUS` codebook vs the trait's `None` default. Arity is what statement segmentation reads, so the same bytes bound into different statements depending on which vocabulary a caller holds. Latent only because `NarsVocabulary` has zero consumers — but this repo pins `ogar-loco` at `branch = "main"`, a floating ref, so the next resolve compiles both into one unit. The older answer is also the better-grounded one: it argues why NOT two (a second operand would have no source), where the newer labels its own 2 as POLICY. Three claims #304 made false are named there too, including `recipe_vocab.rs`'s own module doc, which justifies its LOCATION with a premise that no longer holds. Recommendation recorded, not applied — it crosses two repos and edits a PR the operator just merged. **One row of pre-existing debt, named as such.** STATUS_BOARD gains `D-GTM-0m / P3`. It is not #1240's: the deliverable shipped in an earlier arc and had no status row while its sibling `D-GTM-0n` did, so "where is D-GTM-0m" had no answer on this board. The row carries the bounds EPIPHANIES says a citation of it must carry — one fixture, and `n_gen`/coal as upper bounds. **Regenerate LAST, and this time it was.** SUPERSESSION-INDEX regenerates byte-identical, which is correct rather than suspicious: its board inputs are `entries/*.md` and `EPIPHANIES.md`, neither of which this commit touches. The same gate was red at four SHAs inside #1240 for the opposite reason — the index was regenerated BEFORE the board write, so it read as current while CI recomputed it on the merge commit. Gates, run locally the way CI runs them: `append_only_gate` 9 checked, nothing shrank; `citation_decay --self-test` passed and `--since origin/main` reports "no new citation decay since base"; `plan_dids` no added plans.

cypher-mask-lowering-v1.md§7.0 is a STOP gate: "Nothing is built until Wave 0 answers, with numbers."mask_lowerexists nowhere in the tree — the only hit ismask-risc/src/lib.rs:20naming it as an absence. So the move was to measure, not to write a lowering.W0-b — the corpus census.
crates/lance-graph/examples/w0b_corpus_census.rs(new). The corpus isinclude_str!-ed out of the committed sources and classified through the REALparse_cypher_query+LogicalPlanner::plan, so it cannot drift from the tests it mirrors; every disposition cites the §3/§4 row that rules it.§7.0's STOP condition does not fire. All 40 grace hits land in §4.6's table — 17 on strings and non-integer literals, 17 on order and position, nothing else above two — which is the check that the classifier reads the plan rather than inventing a boundary.
W0-a / OQ-1 — answered by reading, and it is the gate that could have shelved the plan. §1.4 states the
label → classidbinding "does not exist". It does:lance-graph-contract::ogar_codebook::LabelDTOis{ label, id, canonical }, doc-commented as "identity comparison usesid; AST/planner emission usescanonical", withiddocumented as "the classid low u16", andmatch_nodes_by_classalready takes exactly thatu16at the far end. Consumers across the workspace: zero — the only hit outside its own module is its re-export inlib.rs. What is missing is a FIELD, not a mechanism:NodeMappingis{ label, id_field, property_fields, filter_conditions }with nowhere to carry a canonical concept.Two findings the percentages do not contain
9 of the 10 plan-REFUSALS return a bare node variable — measured by inspecting the AST the planner refused, not by eye.
RETURN <node>is §3.5 T-3,Terminal::Keep, "the mask itself": the cheapest thing the mask path can do. The incumbent planner refuses it, and because a refusal is excluded from the denominator, 46.0 % understates the premise by exactly the shape that most favours it.The corpus's labels are not in the codebook.

First run: 15 of 20, 75.0 %. Both runs exited 0. What caught it was enumerating the exclusion buckets instead of counting them — "3 did not parse" is unfalsifiable; printed, the first line read); // Verify the AST structure let ast = result.unwrap(); …. The example now enumerates both buckets, and the fixed extractor skips comments and char literals with the incident in its doc comment.The placement fork was already ruled — a correction I owe on my own work
An earlier commit here left an A/B/C fork open (lowering in core / vocabulary into the contract / a bridge crate). That fork does not exist.
cypher-mask-lowering-v1.md§5.2 ruled it, better than I did:ogar_loco::TERNLOG = 0x86— minted, arity 3, "the call's ONE VALUE BYTE is the 8-bit truth table", and with zero consumers today, so it is a net reduction in unconsumed surface. Nothing is minted.Pred, the hop and the terminals are a lowering target only, by the mechanical test "does a BYTE of this survive the query that produced it?"

Summary by CodeRabbit
⊘ SUPERSEDED BY REVIEW — read this section before any number above it
Two review rounds landed nine findings on this PR. All nine were correct, and
they moved the headline twice. Every figure in the sections above is the
first measurement; these are the current ones.
The body above is left intact rather than rewritten, because the drift is the
point: a PR description is a summary, and a summary is a second place to be
wrong — the place a reader looks first. The same failure appears three more
times inside this PR's own diff, each fixed: the plan's G-F row contradicted
its own body four sections above it; §15's caveat still quoted 46 % after §17.3
had withdrawn it; and the census's module doc said 33 files while the program
it documents printed 27, in the same commit.
Round 1 — four findings

Four extractor/traversal falsifiers now ship, and the example is declared with
test = true— an example'stestflag defaults to false, so a#[cfg(test)]module inside one is compiled and never run.
One of those tests was vacuous on first write: with the raw-string bound
restored,
a_zero_hash_raw_string_is_extractedstill passed, because for aliteral with nothing to escape both branches emit identical bytes. Its doc
claimed to be the falsifier; the claim is corrected in place with the disable
result quoted, and the real falsifier (
a_raw_string_keeps_its_backslashes,["d+"]vs["\d+"]) is named.The Major fix's falsifier walks a nonexistent path rather than a

The conclusion that did NOT change
0 of 303 queries fail to lower. Split is a two-stage plan, not a failure.
§7.0's STOP gate is about whether the full-lowering fraction is negligible, and
on the corrected corpus the answer is the same as on the wrong one.
