1. Move Makefile-based Python workflows onto a repository-managed `.venv`
so install, test, coverage, and e2e all run with the same interpreter and
dependencies.

2. Split environment setup from package installation by adding
`py-env` and `install` targets, keep `build` for wheel creation, and add a
cleanup target. Also ignore `.venv/` and add a `gts/__main__.py` trampoline
so `python -m gts` works reliably from the repo root.

📝 Walkthrough

Walkthrough

The change updates the GTS package for specification 0.13. It adds schema compatibility, derivation, traits, reference validation, UUID-based instances, revised type-oriented APIs, HTTP routes, CLI entrypoints, documentation, tests, and virtual-environment tooling.

Changes

GTS implementation and validation

Layer / File(s) Summary
Tooling, documentation, and entrypoints
.gitignore, .gts-spec, Makefile, README.md, gts/README.md, gts/__main__.py, gts/pyproject.toml, gts/src/gts/__main__.py, gts/src/gts/_cli.py
Development targets, package dependencies, CLI entrypoints, and documentation now describe the updated package and specification.
Identifiers, entities, and operations
gts/src/gts/gts.py, gts/src/gts/entities.py, gts/src/gts/ops.py, tests/test_gts_id.py, tests/test_entities.py, tests/test_ops.py
Identifiers support embedded UUID tails and revised wildcard matching. Entity and operation result fields use type terminology. Failed registrations roll back stored state.
Schema rules
gts/src/gts/compatibility.py, gts/src/gts/derivation.py, gts/src/gts/traits.py, gts/src/gts/store.py, tests/test_compatibility.py, tests/test_derivation.py, tests/test_traits.py, tests/test_regressions.py
The package adds accepted-set compatibility verdicts, derivation checks, trait composition and validation, GTS keyword validation, and schema-chain validation.
Store references, instance validation, and casting
gts/src/gts/store.py, gts/src/gts/x_gts_ref.py, gts/src/gts/schema_cast.py, tests/test_store_extra.py, tests/test_x_gts_ref.py, tests/test_schema_cast.py
The store uses reference registries, validates UUID instances and GTS references, reports compatibility verdicts, and supports the expanded casting behavior.
HTTP and CLI validation surfaces
gts/src/gts/_server.py, tests/test_server.py, tests/test_cli.py
The server exposes /type-schemas, /validate-type-schema, and /validate-entity, with updated request models and compatibility parameters. CLI and handler tests cover the public surfaces.
File reader coverage
gts/src/gts/files_reader.py, tests/test_files_reader_coverage.py
File discovery now uses module logging and direct iteration. Tests cover JSON, YAML, JSONC, multiple paths, invalid files, excluded directories, reset behavior, and unknown identifiers.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 82f18

The current implementation can accept invalid schemas, lose schema entries while loading UUID instances, and report incorrect compatibility results. These failures affect core v0.13 validation behavior and should be fixed before merge.

691-693: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Cache the reference registry across validated instances.

GtsOps.add_entities uses validate=False by default, but repeated validate=True calls reach GtsStore.validate_instance. Each call then scans _by_id, processes every schema, and creates a new Registry, producing O(instances × schemas) work as the store grows. Cache the registry and invalidate it only when a schema is added, replaced, removed, or loaded from the reader. Do not invalidate it for instance-only registration or removal.

Preserve the UUID tail in parse_id results.

For a combined anonymous ID, parsed.gts_id_segments includes a special UUID-tail segment. This mapping converts it into an empty ordinary segment. API clients cannot recover the anonymous instance UUID from the parsed components. Add an explicit UUID-tail field or a typed terminal-segment representation, and add a regression test for ops.parse_id(...).

Proposed direction
 class GtsIdParseResult:
     id: str
     ok: bool
     segments: List[GtsIdSegment] = field(default_factory=list)
+    uuid_tail: Optional[str] = None
 return GtsIdParseResult(
     id=gts_id,
     ok=True,
     segments=segments,
+    uuid_tail=parsed.uuid_tail,
     is_type=parsed.is_type,
     is_wildcard=False,

Remove the extra depth check for ~* queries.

GtsID.wildcard_match defines ~* as matching the base type and its descendants. GtsStore._matches_id_pattern rejects the base type after wildcard_match succeeds. This makes query inconsistent with wildcard_match. Remove the depth check and add a regression test for the base type.

Security Misconfiguration (CWE-1395)

Make security depend on install.

py-env installs only .gts-spec/tests/requirements.txt; it does not install ./gts or resolve gts/pyproject.toml dependencies. pip-audit can therefore omit GTS runtime dependencies that are absent from the test requirements file.

Assert the exact property path for the allOf branch.

The current check also matches "ancestor" and "additionalProperties". An implementation that reports property 'b' instead of property 'a' can pass this test. Use the error format produced by _collect_closed_descendant_branch_errors:

Preserve $ref sibling constraints.

inline_local_pointers can replace a referenced schema keyword with a sibling keyword before validator_for validates the schema. For dialects where $ref siblings apply together, compose the referenced schema and siblings with allOf instead of overwriting matching keywords.

Run the meta-schema check during basic registration.

GtsOps.add_entity always calls GtsStore.validate_schema_basic for schemas. validate=False only skips full validation. validate_schema_basic omits the validator_for(...).check_schema(...) or Draft7Validator.check_schema(...) call, so malformed JSON Schemas can be stored successfully. Add the same dialect-aware meta-schema check used by validate_schema.

Index reader-loaded instances by raw_id before gts_id.

GtsEntity stores a plain UUID in raw_id and infers gts_id from type_id. _populate_from_reader indexes only by gts_id.id, so an instance can replace its type-schema entry. validate_instance(uuid) then cannot find the instance because read_by_id does not support lookup. Apply register’s raw-ID-first branch in _populate_from_reader, with the gts_id fallback for schemas.

- Line 74: Update the request logging around logger.info to neutralize
carriage-return and newline characters in request.url.path before including it
in the log message, while preserving the existing logging behavior for normal
paths.

In `@gts/src/gts/gts.py`:
- Around line 259-261: Update _infer_direction to inspect the last non-UUID-tail
segment rather than the appended UUID-tail segment when determining ver_minor,
preserving correct forward and backward cast ordering. Add a regression test
covering the combined anonymous ID through GtsEntityCastResult.cast.

In `@Makefile`:
- Line 58: Update the make install flow around the wheel installation command to
invalidate INSTALL_STAMP after successfully installing the wheel, ensuring a
later make install-local or make test cannot reuse the stale stamp and skips the
editable reinstall.
- Line 41: Update the $(PY_ENV_STAMP) target prerequisites so it depends on the
Makefile, or on a dedicated dependency stamp that changes when the Python tool
set changes. Ensure adding tools such as ruff and mypy invalidates the existing
environment stamp and reruns installation before make fmt, make lint, or make
mypy.

dialect-aware meta-schema validation as validate_schema, using

while ensuring malformed JSON Schemas are rejected during GtsOps.add_entity
registration.

In `@gts/src/gts/traits.py`:
- Around line 119-123: Update inline_local_pointers so resolved local references
with sibling keywords preserve both schemas: when the fragment contains $ref
plus siblings, compose the referenced schema and sibling schema using allOf
rather than mutating or overwriting matching keywords. Keep the existing
behavior for references without siblings and non-reference fragments.

Invalidate INSTALL_STAMP after installing the wheel.

If make install runs before make install-local, the wheel replaces the editable package while $(INSTALL_STAMP) remains current. A later make test can therefore skip the editable reinstall and import an outdated wheel after source changes. Remove $(INSTALL_STAMP) after the wheel installation, or use separate stamps for editable and wheel installations.

- entities/store: rename graph relation key `schema_id` -> `type_id`
  to match GTS spec v0.10+ terminology (v0.13 rebase); update tests
- x_gts_ref: avoid redundant `_without_x_gts_ref` recomputation in the
  combinator-stripping path to prevent exponential recursion on deep
  single-branch allOf/anyOf/oneOf chains
- Makefile: set `SHELL := /bin/bash` so POSIX recipes don't fall back
  to cmd.exe via COMSPEC on Windows
