-   in-memory. `resolveStoreMode` guarantees production boot FAILS rather

+   search index definitions (`opt_search_index_definitions`, sequential
+   schema versions, replay-idempotent, same-version-different-schema ⇒

+   truth) are Postgres-canonical with real-Postgres tests.

+   Registry") — PARTIALLY CLOSED: the collaboration/meeting domain was

+   capability set still needs the same registration.
+3. CLOSED: AUD0 outbox for evidence durability under AUD0 outage (§70) —
+   durable Postgres outbox + dispatcher (at-least-once, bounded batch,
+   backoff, dead-letter, SKIP LOCKED leasing, tenant binding, idempotency)
+   + real-Postgres tests; dispatcher uses explicit `durable:false` so it
+   never re-enqueues its own delivery evidence.
+4. CLOSED for datasets/versions/search/ER: `app/api/0pt/datasets*`,
+   `app/api/0pt/search/definitions` + tenant-safed query route, and
+   `app/api/0pt/er/{candidates,batch}` (+ internal ER route) are live;
+   clients cannot raise `rights_tag` via request body (fail-closed to
+   `internal`). Quality routes exist (`bridge-run/issues/rules/runs`).
 5. 0pt-motor executors for the delegated jobs
    (`0pt.quality.ge_run`, `0pt.features.*`, `0pt.er.batch_resolution`).
 6. Observability: no metrics/traces emitted by the new services (§36).

-### P065 — why it was not closed
+### P065 — closure record (2026-09-07)
 
-Closing P065 means turning `services/api/workers/resolve.py` into an adapter
-over the canonical `src/er/entity-resolution-service.ts`. That change cannot
-be verified from this repo today: `services/api` is not built by this repo's
-Dockerfile (it builds only the Next.js app), `api.0pt.app` answers 404, and
-no CI workflow runs its pytest suite. A blind rewrite would ship untested
-into a path nobody can exercise — the exact failure mode this programme
-exists to stop.
+The removal plan below was executed in full and is verified in CI:
 
-The removal plan, for whoever picks it up:
-1. Expose the canonical ER capability as `POST /api/0pt/er/candidates`
-   (service already exists; only a route + Zod schema are missing).
-2. Add a Python CI job that actually runs `services/api/tests`.
-3. Replace `resolve.py`'s body with an HTTP adapter over that route,
-   **fail-closed** when it is unreachable — never falling back to the local
-   scorer, which would preserve the duplicate under a different name.
-4. Port `test_resolve_determinism.py` to assert the adapter's contract, and
-   delete the fuzzy scorer.
+1. ✅ Canonical ER exposed as `POST /api/0pt/er/candidates` (public,
+   tenant-safed) AND `POST /api/0pt/internal/er/candidates` (service-token,
+   fails closed without `X-Internal-Token`).
+2. ✅ Python CI job: `.gitea/workflows/python-engine.yml` runs
+   `services/api/tests` as a BLOCKING pytest gate.
+3. ✅ `workers/resolve.py` rewritten as the HTTP adapter — fail-closed to
+   UNMERGED records when the bridge is unreachable; no fallback scorer
+   remains. Cluster-wide hard-negative constraints prevent transitive
+   matches from overriding canonical identity decisions.
+4. ✅ `services/api/tests/test_resolve_determinism.py` asserts the adapter
+   contract: canonical match edges merge; review/non-match edges do not;
+   hard negatives are respected transitively.
+
+Residual honesty: the PYTHON-side tests run in CI, but the full
+adapter→Next.js route chain has not been exercised against a live deployed
+edge in this branch (the route's own fail-closed behavior is unit-proven).
+That keeps P065 at INTEGRATION_TESTED, not LIVE_VERIFIED.
