   - Wire the gRPC `slot_lookup` seam (address→names from the current slot) so on-demand reads persist; if the lookup becomes I/O-bound, move it inside the servicer's try/except.
   - gRPC server is internal-only, no auth (no consumer yet — likely frontend later, per feature owner).
   - Edge case (minor): `read_now` with `SourceTimestamp=None` persists `timestamp=None`; add a guard if it matters in practice.

+- Deferred by design (verified in Task 21): NTP sync + `Good_Local_Override` quality downgrade (no flag exists; ties to a real clock-drift case), write-via-OPC-method (card marks it flag/future). Pre-existing legacy files >500 lines (`ingestor_manager.py` 578, `opc_manager.py` 507) flagged, untouched (predate the gateway).
+- Integration gates (cross-repo): subscription v2 swap + gRPC persist → SIENTIAPDE-1974; write_status column (Flyway) + Laborious NATS publish → SIENTIAPDE-1975; NATS broker in cluster → SIENTIAPDE-1985. End-to-end validation (real NATS + OPC server machine) agreed with the feature owner for deployment time.
 
 ### Final: open per-phase PRs (only after F4 is complete, tested, working)
 Since all phases live on one feature branch, split them at the end using the recorded SHA ranges: for each phase in order F0→F4, create a phase branch off `main` (or stacked on the previous phase branch) containing only that phase's code commits (cherry-pick the ledger's SHA range), then open one PR per phase targeting `main`, in phase order. This keeps each PR small and reviewable instead of one giant diff.

 ### Task 21.end: F4 close-out + open per-phase PRs (see [Phase Delivery](#phase-delivery--commit-ledger))
-- [ ] Full `pytest tests` green + `ruff` clean; all F0–F4 phases complete, tested, working.
-- [ ] Record F4 commit SHAs (base + range) in the [Commit Ledger](#commit-ledger).
-- [ ] **Now** open one PR per phase (F0→F4) from the recorded SHA ranges, in order — this is the only point where PRs are opened.
