All required CI green (Change scope/Static PR checks/Safety/Unit coverage/Build). PR policy check genuinely FAILS and is unfixable within Run PR guardrails: PR touches RAG-ranking-protected src/lib/rag/rag-row-contracts.ts (nullable->nullish widening on source_metadata schema) with no RAG impact: line in the PR body, and the diff also lacks the required Clinical Governance Preflight section -- both are hard pr-policy.mjs blockers per AGENTS.md. Separately, trust/integrity spot-check: PR body claims 15 delivered resolutions but the diff (both commits combined) contains only 14 outstanding-issues-inbox JSON tickets; ticket #178 (PR policy clinical/operational bundling detection) is described in prose with a specific file:line citation but has no corresponding inbox JSON file in either commit -- it was never actually queued, unlike #098/#118 which appeared twice and were deduplicated in the second commit. The 14 tickets that do exist were spot-checked against origin/main (search-route-round-trip-budget.test.ts, guard-push.mjs prettier exact-lock logic, tests/helpers/source-contract.ts, scripts/ledger-inbox.mjs, pr-policy.mjs:335 bundling warning) and all matched their claimed outcomes -- unlike PR #2105, this is an omission/inflated count, not fabricated ledger content. No unresolved review threads (0). No CI job fixed by this session; PR policy failure and the missing RAG-impact declaration are left for a human, per guardrail against editing PR titles/bodies. | GitHub-side CI only (no local checks run -- worktree has no node_modules and only Node 22 available, repo requires Node 24; PR policy job log inspected directly via get_job_logs). No provider-backed gates run. update_pull_request_branch used for drift sync (GitHub-side merge, not a local git operation). |

+Following a Supabase database restore or disaster recovery failover, verify all 5 environment-owned controls before admitting production traffic:
+
+1. **API Secrets & Keys Parity:** Confirm `SUPABASE_SERVICE_ROLE_KEY`, `OPENAI_API_KEY`, and `RAG_QUERY_HASH_SECRET` match the restored project environment.
+2. **Webhook Endpoint & Signature Verification:** Confirm Railway webhook destinations and Supabase Database Webhook triggers are active and matching HMAC secrets.
+3. **Authentication & Connection Limits:** Validate auth rate limits and connection pool percentage allocation in the Supabase Dashboard.
+4. **Cron Job Schedule Registration:** Verify pg_cron extensions and scheduled maintenance jobs (cache retention, query log sweeps) are active.
+5. **Storage Bucket Policies:** Confirm private document storage buckets (`documents`, `document-images`) have active RLS policies preventing unauthenticated public reads.
