Roll to gts-spec v0.14.4 and decompose the store/validation layer - #3

Bump the conformance target in .gts-spec-version to v0.14.3 (README updated to match) and introduce a solution-wide Directory.Build.props that owns the shared TargetFramework/Nullable/ImplicitUsings settings and pins the package Version at 0.1.0. Per-project csproj files drop the now-redundant properties. Gts.Store gains the JsonPointer.Net reference and Gts drops its explicit System.Text.Json package (provided by the shared framework on net8.0). The Gts.Store assembly now exposes internals to Gts.Tests for unit coverage. Signed-off-by: Artifizer <artifizer@gmail.com>
Add GtsConstants for the shared "gts."/"gts://" prefixes and traversal limits so the magic literals (notably the "gts://".Length slice) no longer appear inline across the codebase, and extract identifier decomposition into a dedicated GtsIdParser (ParsedGtsId). GtsId and the JSON entity extraction are reworked to build on these, keeping segment parsing in one canonical place. Signed-off-by: Artifizer <artifizer@gmail.com>
Introduce an in-tree JSON Schema engine (GtsJsonSchemaEngine behind IGtsJsonSchemaEngine) with supporting JSON helpers (GtsJson, GtsJsonPointer), a format registry/validator (GtsFormatRegistry, GtsFormatValidator), and route the evaluator, document normalizer, and minor-version canonicalizer through it. This gives GTS control over dialect handling and format checks instead of relying solely on the third-party validator. Covered by JsonInfrastructureTests. Signed-off-by: Artifizer <artifizer@gmail.com>
Replace the stringly-typed FailureReason fields on the validation, cast, and schema result records with a closed GtsValidationFailure set, exposing a ToWire() helper for the external string form. Producers and consumers now share one enumerated set of reasons instead of matching on magic strings. Signed-off-by: Artifizer <artifizer@gmail.com>
Break the monolithic GtsRegistry apart into single-responsibility services: schema validation (GtsSchemaValidationService, GtsTypeSchema, keyword/traits validators, GtsSchemaKeywords), instance validation (GtsInstanceValidationService), casting (GtsCastService), compatibility (GtsSchemaCompatibilityService), and x-gts-ref handling (GtsRefValidator, GtsRefConstraint, GtsRefValidationMode, GtsSchemaDependencyGraph, GtsTraitComposer). GtsRegistry and the in-memory registry/store are reduced to thin orchestrators over these services; the derivation, ref-format, evolution, and minor-version compatibility helpers and IGtsStore are updated to the new shape. Snapshot handling in the in-memory store is hardened alongside. Signed-off-by: Artifizer <artifizer@gmail.com>
Carve the oversized GtsHttpApiExtensions into focused parts: request/response DTOs in GtsHttpContracts, endpoint wiring in GtsOperationEndpoints, and shared logic in the GtsHttpApiHelpers partial. Entity operations and registry bootstrap are updated to the decomposed store services and typed failures. Signed-off-by: Artifizer <artifizer@gmail.com>

`GtsTypeSchema.TryGetSupportedDialect` and preserve the existing behavior for
valid dialect strings.
In `@Gts.Store/GtsInstanceValidationService.cs`:
- Around line 17-18: Update the blank-instanceId branch in the instance
validation method to pass the existing GtsValidationFailure.InvalidInstanceId
value to Failure instead of null, so failed validation includes a specific
FailureReason.
In `@Gts.Store/GtsJsonSchemaEvolutionCompatibility.cs`:
- Around line 169-170: Update the root-level items type check in
GtsJsonSchemaEvolutionCompatibility to allow integer-to-number widening for
backward checks and number-to-integer narrowing for forward checks, matching the
compatibility rules already applied to property item types. Continue reporting
other item type changes as errors.
In `@Gts.Store/GtsQuery.cs`:
- Line 64: Update the wildcard validation in GtsQuery to require basePart to
start with GtsConstants.IdPrefix before accepting it; preserve the existing
wildcard-count and delimiter checks so malformed patterns such as foo.* and

In `@Gts.Store/GtsRefConstraint.cs`:
- Around line 23-25: Update GtsRefConstraint.Matches to use GtsId.TryMatch so
exact and wildcard constraints follow the shared matching rules and enforce
segment boundaries. Preserve the special handling for the IdPrefix wildcard if
GtsId.TryMatch does not cover it.
In `@Gts.Store/GtsRefValidator.cs`:
- Around line 138-152: Update the oneOf/anyOf branch handling in WalkInstance to
count only branches containing x-gts-ref, including nested references; treat
branches without references as neutral. Apply reference-match errors only to
relevant branches, leaving structural oneOf/anyOf validation to the JSON Schema
engine.
In `@Gts.Store/GtsSchemaDependencyGraph.cs`:
- Around line 93-101: Update Resolve to evaluate any `$ref` fragment against the
loaded document with GtsJsonPointer.TryEvaluate, resolving the referenced
subschema rather than the whole document. Preserve non-`$ref` sibling keywords
by composing them with the resolved target, while retaining existing cycle
handling.
In `@Gts.Store/GtsSchemaRefFormatValidator.cs`:
- Around line 23-24: Update the local-reference check in
GtsSchemaRefFormatValidator to percent-decode fragments before passing JSON
Pointers to GtsJsonPointer.TryEvaluate. Treat fragments that do not start with
`/` as anchors and avoid rejecting them as invalid pointers; resolve declared
anchors if supported, otherwise skip the existence check for those fragments.
In `@Gts.Store/Validation/GtsJsonSchemaEngine.cs`:
- Around line 54-63: Update the `Compile` call in the method that computes
`reachable` and `fingerprint` to pass only the reachable schema closure, rather
than the full `schemas` dictionary. Keep the existing fingerprint and
compilation flow unchanged so each cached registry captures only schemas
reachable from the root.
In `@Gts.Store/Validation/GtsSchemaDocumentNormalizer.cs`:
- Around line 74-83: In GtsSchemaDocumentNormalizer, update the branch
normalization loop to preserve validation when oneOf branches contain x-gts-ref:

Preserve the existing handling of empty branches and avoid overwriting an
existing anyOf.

GetValue<string>() throws when $schema is not a string.
oldEntity.Content["$schema"]?.GetValue<string>() throws InvalidOperationException when the stored $schema is a number or an object. The bulk route and /type-schemas store schemas with validate: false. In that mode a malformed $schema can still reach storage if dialect checks are bypassed. The global exception handler then returns a 500. The same call pattern appears on lines 77 and 99. Use TryGetValue<string> or GtsTypeSchema.TryGetSupportedDialect.

The blank-id failure path returns no FailureReason.
Failure(instanceId, null) returns Ok = false with FailureReason = null. GtsInstanceValidationResult documents null as "null on success", so callers cannot tell why validation failed. GtsHttpApiHelpers.InstanceError falls back to the generic "Validation failed" text. Use the existing InvalidInstanceId value.

The root-level item type check does not allow integer/number widening.
Lines 148-151 allow integer→number for backward checks and number→integer for forward checks on property item types. The root items check at Line 169 does not. A root array schema that widens its item type from integer to number is therefore reported as backward-incompatible, while the same change inside a property is accepted.

Require the gts. prefix on wildcard queries.
Before this change, GtsId.TryParsePattern validated wildcard base patterns. The new check tests only the * count and the character before *.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The new local-reference check rejects valid plain-name and percent-encoded fragments.
GtsJsonPointer.TryEvaluate removes the # and parses the rest as a JSON Pointer. Two kinds of valid local references then fail:
- Plain-name fragments: a reference such as
#addresstargets an anchor declared with$anchor(2019-09 and 2020-12) or$id: "#address"(draft-07).JsonPointer.TryParse("address")fails because a pointer must start with/. - Percent-encoded fragments: a URI fragment such as
#/definitions/a%20bis not decoded, so the pointer segmenta%20bdoes not match the keya b.
TryAddAsync and GtsSchemaValidationService.ValidateAsync call this validator on every schema, so these schemas are now rejected at ingest with InvalidRefFormat.
Treat a fragment that does not start with / as an anchor. Either resolve it against $anchor or $id declarations, or skip the existence check for it. Decode the fragment with Uri.UnescapeDataString before pointer evaluation.

Address the review findings on PR #3: - GtsRefConstraint.Matches: enforce a segment boundary for exact (non-wildcard) x-gts-ref patterns. Plain prefix matching accepted "...w.v1" against "...w.v12"/"...w.v1.5", so a reference to a different registered instance passed validation. Require a full match or a '~' boundary right after the pattern; type patterns (ending in '~') still admit derived identifiers. - GtsSchemaDependencyGraph.Resolve: evaluate the $ref JSON Pointer fragment against the loaded document and preserve $ref sibling keywords (composed via allOf), so fragment references and the siblings that 2019-09/2020-12 apply are no longer dropped. - GtsJsonSchemaEngine: compile against the reachable schema closure instead of the whole registry, so each cached JsonSchema no longer retains an O(store size) snapshot through its registry.Fetch closure. - GtsSchemaDocumentNormalizer: evaluate a oneOf whose branches differ only by x-gts-ref as anyOf. After x-gts-ref is stripped the branches collapse to identical schemas and oneOf rejected every value; exclusivity is enforced separately by GtsRefValidator. Documented why dotnet uses this normalization while gts-go/gts-rust register a real keyword (JsonSchema.Net exposes no public API to add a keyword to a built-in dialect). - GtsIdParser.TryParse: validate the bare canonical id and reject the gts:// URI form, matching the gts-rust/gts-go reference parsers. The scheme is stripped by $id/$ref-specific callers before parsing, which removes the query/parse-id inconsistencies caused by accepting it here. Signed-off-by: Artifizer <artifizer@gmail.com>
The instance-level x-gts-ref pass counted a oneOf/anyOf branch as "matching"
whenever it produced no x-gts-ref errors. A branch that declares no
x-gts-ref (for example the {"type":"null"} arm of a nullable reference) is
never inspected structurally by this pass, so it always produced zero errors
and was counted as a match. For the common nullable shape
oneOf: [{"type":"string","x-gts-ref":"..."}, {"type":"null"}] a valid string
reference therefore matched both branches, and oneOf's exactly-one rule
rejected a valid value.
Only branches that actually declare an x-gts-ref (directly or nested) now
participate in the match count; branches without one are treated as neutral,
leaving structural oneOf/anyOf selection to the JSON Schema engine. This
aligns the .NET implementation with the other GTS implementations and is
covered by the new gts-spec nullable-reference conformance case.

…chemas Batch type-schema registration previously ignored the request query string: every entry was added with validate: false and the gts-ref-validation mode was never parsed. This diverged from POST /entities, where those parameters control per-entry validation. Parse gts-ref-validation up front so a malformed mode is rejected with 422 before any entry is registered, and thread the validate flag and mode through TryAddAsync so each batch entry honors them exactly as the single-entity endpoint does.

Add a staging overlay to the in-memory store: staged entities are included in SnapshotForReadAsync (used by validation) but excluded from committed reads (GetAsync / GetByInstanceIdAsync / query) until CommitStagedAsync. Batch POST /type-schemas?validate=true now stages every entry, validates each against the fully-staged set, then commits the survivors and discards the rest, so an invalid entry is never observable and the batch is order-independent (an entry may resolve $ref / inheritance to a later sibling). Add a concurrent staging-isolation test. Signed-off-by: Artifizer <artifizer@gmail.com>

…endency-safe The two-phase POST /type-schemas?validate=true flow had three defects: staged entries leaked if an exception occurred before the commit phase, a survivor could be committed even though a staged sibling it depends on was discarded, and staging keyed purely by entity id let concurrent batches (or a duplicated batch entry) clobber each other while commit bypassed the conflict check. - Key the staging overlay by a unique token instead of the entity id, so two entries that resolve to the same id never overwrite each other and a commit/discard only affects the entry it names. - Commit atomically with a compare-and-swap against the committed store, returning GtsSaveOutcome so a conflicting publish is reported rather than silently overwriting existing content. - Track pending tokens and discard the leftovers in a finally block, so a throw anywhere in the batch never leaves unvalidated entries in the read overlay. - Iteratively discard failures and re-validate the survivors against the now-smaller staged set until a round is clean, so nothing is committed with a dangling parent or reference to a discarded sibling. Adds store-level tests for token isolation and compare-and-swap commit. Signed-off-by: Artifizer <artifizer@gmail.com>

JsonSchema.Net 9.1.3 compiled `pattern` / `patternProperties` with
Regex.InfiniteMatchTimeout, so an untrusted schema carrying a catastrophic
backtracking pattern (e.g. (a+)+$) matched against an adversarial instance
value could pin a CPU indefinitely (CWE-1333). Setting the process-wide
default match timeout does not help — the library explicitly opts out of it.
Upgrade JsonSchema.Net to 9.4.0 (and JsonPointer.Net to 7.0.2 to satisfy
its dependency), which bounds regex match time internally and raises
RegexMatchTimeoutException instead of hanging. Catch that exception on the
instance-validation and cast paths and surface it as a validation failure
("regular expression match timed out"), mirroring the runtime match-timeout
protection in gts-go and gts-python. The schema-traits and x-gts-ref
existence paths already convert evaluation exceptions to failures.
Adds a regression test asserting a catastrophic pattern against a 40k-char
adversarial instance returns a bounded failure rather than hanging.

The validate=true registration overlay was global: one request's staged, not-yet-validated entries were visible to another request's validation, so a batch could resolve a parent or $ref target against another batch's unvalidated entry and commit a dangling reference. Separately, the batch commit loop published survivors one-by-one, so a dependent could be published against a target whose committed content changed after the dependent had been validated. Scope the staging overlay to a per-request staging session (committed-only when no session is active) so a batch resolves only its own siblings, and replace the per-entry commit loop with a store-level all-or-nothing batch compare-and-swap that publishes nothing when any target conflicts.
