Batches with a duplicate entry or a wildcard reference to a staged sibling are rejected incorrectly. Resolve these issues before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Batch publication protects against partial writes, but a concurrent change to a schema dependency can leave a validated batch committed against a different dependency than the one it checked.

Normalize the trait schema before compiling it.
validateTraitsAgainstSchema copies the host $schema into cleanedTraitSchema and compiles that schema independently. It does not call normalizeSchemaForCompile. Therefore, an accepted case-folded dialect URI can reach the compiler unchanged and fail dialect resolution.
Make normalizeSchemaForCompile canonicalize $schema, then apply it to the cleaned trait schema before registration:
Suggested fix
if schema, ok := hostSchema["$schema"].(string); ok {
cleanedTraitSchema["$schema"] = schema
}

Cap the accepted-instance-set inclusion checker at a fixed nesting depth. $ref resolution inlines other documents before the walk runs, so a resolved tree can be far deeper than anything authored; past the cap the relation is reported as unknown rather than read as a proof, which also removes an unbounded-recursion stack-overflow risk on adversarial input. Enrich the /compatibility response with additive, non-spec-tested detail: per-direction error reasons, is_*_compatible flags, structured diagnostics (direction + verdict + message), and a section 4.4 content-model classification of the resolved candidate schema (open / closed / partially_open per object level). The three verdicts are unchanged, so the conformance suite is unaffected. The diagnostics reducer and the content-model classifier mirror the gts-rust reference: verdictFromDiagnostics reads the verdict off its evidence, and classification is dialect-aware for unevaluatedProperties, distinguishes all-open/all-closed patternProperties, treats a boolean propertyNames as closing, flattens each level's allOf, and walks only properties and single-schema items.

Memoize compiled JSON schemas keyed by id plus a content hash, cleared on every mutation. A generation counter guards the cache against an invalidation that races an in-flight compile: each entry records the generation observed when its compile began and is reused only while that generation is still current, so a Store landing after a concurrent Clear cannot resurrect a stale result. Faulting an instance in through the reader no longer flushes the cache, since only a type schema can affect a compiled result. Serialize on-demand reader faults on a dedicated lock, distinct from the writer lock, so a validation callback running inside a registration transaction can still fault entities in via Get without self-deadlocking. Replace store.Items(), which deep-clones the entire registry, with forEachEntity for read-only scans under the read lock and entityIDs() for key-only scans, deep-copying only the entities actually returned. Where a scan must call back into the store (trait wildcard matching), it iterates an ID snapshot rather than holding the read lock. Detect a missing referenced schema through a typed error instead of matching on message text, and fold in assorted cleanups: a shared deep-copy helper, slices.Sort/Contains, and an isolated JSON Schema type-mismatch message adaptation.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Guard booleanSchemaValue against nested not recursion.
booleanSchemaValue recurses without a depth limit through {"not": {"not": ...}} chains. The function is reached from isAcceptAllSchema and from classifyObjectLevels through patternProperties, propertyNames, and fallback values. resolveRefs can inline registered documents, so the resolved content can come from user-registered schemas. A very deep not chain can exhaust the stack. maxCompatRecursionDepth caps the other walkers in this file but does not cap this one. Apply the same cap here and return nil (not reducible) when the depth reaches the cap.

Seed the walk from every type in the chain, and run the local-$ref check per member, matching the whole-closure validation the instance path and the Rust reference already perform. A type is only as valid as the types it builds on (spec 11.0/12). Signed-off-by: Artifizer <artifizer@gmail.com>
For a non-wildcard x-gts-ref pattern, prefix matching alone ignored segment boundaries: "...w.v1" also accepted "...w.v12"/"...w.v1.5", so a reference to a different registered instance passed validation. Require a full match or a '~' boundary immediately after the pattern for exact patterns; type patterns (ending in '~') still admit derived identifiers. Signed-off-by: Artifizer <artifizer@gmail.com>
The x-gts-ref vocabulary returned success for the /$id self-reference, deferring it to the separate XGtsRefValidator pass. But the JSON Schema engine performs oneOf/anyOf branch selection, so a /$id branch matched every string. In a oneOf that mixes a /$id branch with a concrete sibling pattern, a value matching only the sibling satisfied both branches and the exactly-one rule rejected a valid value; the separate pass runs afterwards and cannot undo it. Thread the bare id of the type being validated into the vocabulary (mirroring the gts-rust design) so /$id resolves to that type and participates in branch selection like any other pattern. The selected id is derived from the schema being compiled, so the compiled-schema cache stays correct. Registry existence still stays with XGtsRefValidator.

…chemas Batch type-schema registration went through registerTypeSchema, which called store.RegisterSchema directly and never looked at the query string, so ?validate and ?gts-ref-validation were silently dropped. This diverged from POST /entities, where those parameters drive per-entry validation. Extract the single-entity registration pipeline into addEntityResult and route both handleAddEntity and each POST /type-schemas batch entry through it, so batch entries honor ?validate / ?gts-ref-validation exactly as the single-entity endpoint does. gts-ref-validation is parsed up front so a bogus mode is rejected with 422 before any entry is registered. The batch-specific $schema/$id presence and type-id checks now reject a missing $schema, a non-gts:// $id, or a malformed identifier. Adds a handler test covering forward-reference acceptance without validate, rejection with it, and the 422 for a malformed mode. Signed-off-by: Artifizer <artifizer@gmail.com>
…rlay Add a staging overlay to the store: staged entities are visible to internal validation and $ref/chain resolution (Get) but invisible to public reads (GetCommitted / List / Query) until Commit. A validate=true registration stages, validates, then commits on success or discards on failure, so a concurrent reader never observes an unvalidated entity and no write lock is held across validation. Batch POST /type-schemas?validate=true now runs two-phase - stage every entry, validate each against the fully-staged set, then commit the survivors and discard the rest - making it order-independent while never publishing an entry that fails. Add a race-detector concurrency 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 a panic 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, with a by-key overlay for internal resolution, 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 an EntityConflictError so a conflicting publish is reported rather than silently overwriting existing content. - Track pending tokens and discard the leftovers via defer, so a panic 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 handler tests for the dependent-of-discarded and duplicate-id cases. Signed-off-by: Artifizer <artifizer@gmail.com>

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.

Report intra-batch duplicates per entry. Do not reject every entry with a false conflict message.
Stage checks conflicts only against committed entities in byID. It does not check other staged entries. A single batch can therefore stage two entries with the same key and different content when AllowEntityUpdates is false.
CommitBatch finds the conflict through pendingByKey. It then sets anyConflict and gives every token an EntityConflictError. Each entry's error names that entry's own key. An unrelated valid entry therefore gets the error "Entity '' is already registered with different content". That id was never registered, so the message is wrong for that entry.
stageAndValidateBatch in server/handlers.go also cannot tell this case apart from a real concurrent conflict. A single duplicate in the client payload rejects the whole batch. The response does not identify the duplicate entry.
The all-or-nothing rule is correct for concurrent conflicts. An intra-batch duplicate is a client input error, so the handler can detect it before CommitBatch runs. In Phase 1, track staged keys and their contentHash values. When a later entry has the same key and different content, fail that entry with a specific error. Also give non-conflicting siblings a batch-level error, such as "batch rejected: sibling conflict on ''", instead of a false "already registered" message.

Resolve wildcard x-gts-ref targets against the staging session.
The wildcard path uses forEachEntity, which scans committed byID only. A validate=true batch can therefore miss a matching sibling in stagedByKey[v.session], while an exact reference resolves it through getScoped.
Apply the session to both wildcard scans. Keep forEachEntityScoped for the x-gts-ref scan, but use an ID snapshot for hasValidWildcardMatch because its callback calls validateEntity and re-enters the store. Ignore the empty session so private staged entries remain invisible.
