SonarCloud:
- Resolve 6 S5332 hotspots (http→https in test fixture URLs).
- S6418: hoist the unauthenticated AsyncOpenAI placeholder to a named constant
+ NOSONAR (genuine non-secret; gateway ignores it when unauthenticated).
- Fix two reliability bugs: None-index guard in the gateway token-cache test
(S2259) and float `> 0.0` instead of `!= 0.0` in the sentinel test (S1244).
- status.py idle path sleeps 0.1s instead of sleep(0) (S7491); NOSONAR on the
protocol-required async no-await aclose() stubs (S7503).
Claude review:
- Remove three leftover debug print() calls in app.py (logger.info already
covers them).
- payload_backfill: drop parsed_at from the backfilled-keys docstring (it is
per-document state, not a deployment scalar); add a clean 404 precondition
for BasicAuth deployments without an OAuth token verifier.
- status.py: task_status typed TaskStatus | None (drop type: ignore).
- nats.py: TODO to thread etags for file/deck/news; note etag default → None.
- factory: warn on unknown INGEST_BUS_URL scheme; raise ValueError instead of
assert for the external-mode preconditions.
- docs/configuration.md: document the decomposition hook-point env vars + that
nats-py ships core (lazy-imported) and external+bus uses two NATS connections.
