📝 Walkthrough

Walkthrough

The change publishes GTS version 0.14.0, centralizes schema traversal, updates schema and trait validation, changes entity dispatch for registered entities, and adds a configurable server target.

Changes

GTS validation and release updates

Layer / File(s) Summary
Schema traversal and validation
gts/src/gts/schema_validation.py, gts/src/gts/store.py, tests/test_store_extra.py, tests/test_x_gts_ref.py
Shared traversal and mapping utilities replace manual recursion. Schema keyword checks, dependency discovery, and x-gts-ref validation now distinguish schema keywords from annotation data.
Trait validation integration
gts/src/gts/traits.py, tests/test_traits.py
Trait validation removes required keys from derived schemas only when unresolved checks are disabled. Other type checks and unresolved x-gts-ref checks remain active.
Entity validation dispatch
gts/src/gts/ops.py
Registered entities use their stored is_schema value to select schema or instance validation. Unregistered entities continue to derive the type from the GTS ID.
Server command and version metadata
Makefile, README.md, gts/README.md, gts/openapi.json, gts/pyproject.toml, gts/src/gts/_server.py
The Makefile adds a configurable loopback server target. Documentation, package metadata, OpenAPI metadata, and the FastAPI application now use version 0.14.0.

Change: Bug fix

Merge Risk: 🟡 Moderate · up to e1c0a

Some valid schemas can bypass nested constraint and dependency validation, including relative references and Draft-3 subschemas. Address these validation gaps before merge.

required keys from data-valued keyword contents such as const and enum, changing
validation semantics. Replace the recursive schema-tree rewriting used by
_validate_trait_values when check_unresolved=False with a validation approach
that ignores the JSON Schema required keyword itself while preserving required
keys inside const, enum, and other data-valued keywords; keep ordinary type
validation active.

Comment thread gts/src/gts/schema_validation.py
gts-spec v0.14.0 requires that an x-gts-ref value always resolve to a
registered entity, uniformly across all constraint forms (including the
bare "gts.*" wildcard and unregistered constraint types). Trait
validation previously only checked existence when the constraint type
itself was registered, letting "gts.*" and missing constraint types pass.

- Always enforce referenced-entity existence when a store is available.
- Replace the misleadingly-named require_registered_target flag with
  enforce_existence (default True), which honestly gates the check.
- Bump supported spec version to 0.14.0 across package metadata, READMEs,
  OpenAPI, and the server title.

Check every external GTS $ref target during explicit schema validation, including complete multi-segment identifiers. This keeps /validate-type-schema and /validate-entity from accepting schemas whose referenced Type Schemas are absent.

Signed-off-by: Artifizer <[email protected]>
Treat annotation payloads and property-name maps as data when validating GTS extensions and collecting dependencies. Preserve nested schema traversal, including x-gts-traits-schema, without interpreting keyword-shaped data as constraints.

Signed-off-by: Artifizer <[email protected]>
Remove required only from actual trait subschemas when validating abstract types. This keeps annotation data intact and prevents nested schemas with their own dialect declaration from restoring completeness checks.

Signed-off-by: Artifizer <[email protected]>
Resolve slash-prefixed x-gts-ref constraints against their root schema before checking target existence or collecting transitive dependencies. This keeps relative references subject to the same registry and dependency validation as concrete constraints.

Signed-off-by: Artifizer <[email protected]>
Visit schema-valued extends, type, and disallow forms in the shared schema walkers while preserving scalar forms. Resolve relative trait references before extracting subschemas so validation retains the host document context.

Signed-off-by: Artifizer <[email protected]>
Allow bulk registration to store schemas whose relative x-gts-ref pointers require explicit validation, while keeping single registration strict. Recognize the validation query alias so callers can request eager semantic checks consistently.

Signed-off-by: Artifizer <[email protected]>
Apply x-gts-ref constraints at the correct indices for Draft-07 tuple items and Draft 2020-12 prefixItems schemas.

Signed-off-by: Artifizer <[email protected]>
Expose typed syntax-only, presence, and full reference validation through
native and HTTP APIs while retaining full validation by default.

Signed-off-by: Artifizer <[email protected]>
Restrict x-gts-ref operands to concrete GTS identifiers, wildcard patterns, and the reserved /$id form. Remove general pointer resolution and the bulk-registration bypass so unsupported pointer syntax is rejected consistently.

Propagate the selected leaf type through instance and effective-trait validation so inherited /$id constraints rebind correctly. Update unit coverage and fix the server's validation-mode default typo.
