- new gateway::schema_cache — PublishSchemaCache: compile the op's
publish_schema once per registration (value-keyed invalidation for
hot reload), cache compile failures (logged once at error level,
never retried per request)
- /publish compile failure is now fail-closed: the chunk stream
terminates with INTERNAL (500), the error text stays in the log
(no schema internals on the wire) — the per-request warn-and-skip
unvalidated ingest path is removed
- schema resolution is lazy (first chunk poll, after invoke_sink's
404/403/422 pre-checks — GW-11 order preserved) and keyed by schema
value, so re-registration/hot reload is picked up (test)
- NdjsonChunkStream: first Err item is terminal (done + stream end),
mirroring the wire pump's send(Err) + break — Ok chunks can never
follow an error on the HTTP path either (found by spy-handler test)
Verified: cargo test (308), cargo test --all-features, clippy
--all-targets -D warnings (default + all-features), fmt --check.
Tasks: review-001-publish-schema-validation-robust
Found in the sweep of completed review-001 remediation:
- /publish schema validation fails open on compile error + recompiles
per request (remediation-introduced, routes.rs:254-268)
- OAI-06 loud-degradation unblocked and still open (HTTP_0 marker)
- HY-06 ExponentialBackoff in public API + COV-02 mTLS success path
both unblocked post client-config rework
- HY-02/04/11 publish-prep docs gate (104 missing-docs warnings
re-measured)
Also flagged, not tasked here: WS-12 (alkcall demux 4 GiB discard
alloc) was never actually filed in alkcall's consumer-findings-ledger —
only CF-001 is there. File it when next touching alkcall.
