Subject: [PATCH 01/18] Fix content access gaps for anonymous and public
 document users

- Degrade invalid bearer tokens to anonymous scope instead of 401
- Allow public document read routes (list, detail, signed-url, search, images)
- Align registry routes with medications/differentials auth-signal short-circuit
- Let DocumentViewer load public sources without requiring sign-in
- Add regression tests and update access-control expectations

Subject: [PATCH 02/18] Reconcile search_schema_health index drift on live
 Supabase

Create missing retrieval-support indexes (trgm, composite btree, partial
miss log) that were absent or only present under legacy names on live.
Update search_schema_health() to accept verified functional equivalents
during rollout. Set search_path for pg_trgm gin_trgm_ops in extensions.

Verified on linked project: search_schema_health() ok=true, missing=[].

Subject: [PATCH 03/18] fix(db): reconcile live drift and harden security
 without RAG regression

- Re-apply indexing_v3_agent_jobs table and claim/update RPCs on live

- Codify match_document_embedding_fields_text with service_role-only execute

- Enable RLS on rag_visual_eval_* tables

- Fix edge function JSONB status RPC parsing

- Harden owner-scope and health deep-probe gating

- Restore .env.example; remove unused postgres npm dep

- Make gold-label governance advisory-only

+
+- `indexing_v3_agent_jobs` table and claim/update RPCs (recorded as applied in history but absent on live at inspection time)
+- `match_document_embedding_fields_text` RPC with service-role-only execute grants (was present on live with anon/auth execute)
+- `rag_visual_eval_cases` / `rag_visual_eval_runs` tables with service-role-only RLS (were present on live without RLS)
+
+`supabase/schema.sql` has been reconciled to match. Apply the migration through the normal linked workflow when ready; do not use raw dashboard SQL for retrieval RPCs.

+The repo also includes additional July 2026 migrations beyond the June checkpoint above, including:
 
 - Retrieval RPC codification and hybrid execution smoke (`20260701140631`, related July 1 fixes)
 - Legacy vector index drops and `search_schema_health()` reconciliation (`20260702014803`, `20260702021604`)

   - Auth server is capped at 10 absolute DB connections (Supabase advisor); switch to percentage-based allocation in the dashboard before scaling instance size (not settable via SQL/MCP).
   - `storage_cleanup_jobs` live indexes drifted from `supabase/schema.sql`: live carries legacy auto-names (`storage_cleanup_jobs_document_id_idx`, `storage_cleanup_jobs_owner_id_idx`, a non-partial `storage_cleanup_jobs_status_created_idx`) that the hardening defs superseded. Migration `20260703030000_reconcile_storage_cleanup_jobs_indexes` is **prepared but NOT applied** — it drops the legacy names and (re)creates the intended named/partial indexes to match schema.sql. Functional-not-broken (the document_id FK is covered), so apply to live only with explicit approval. `20260703000000`/`010000` are also absent from live `schema_migrations` and will self-heal on the next `supabase db push`.

 ## PR merge gate: tiered CI + required checks (2026-07-02)
 
 - CI is now two parallel PR jobs instead of one serial 6-7 minute job: `verify` (runtime alignment, edge typecheck, CI-safe production readiness, lint, typecheck, unit tests with coverage gate, build — ~3 min) and `ui-smoke` (Chromium Playwright smoke against its own dev server — ~4.5 min). Wall-clock PR feedback drops to the slower of the two, and a flaky smoke rerun no longer repeats lint/typecheck/tests/build.

Subject: [PATCH 09/18] fix(db): reconcile live drift and harden security
 without RAG regression

- Re-apply indexing_v3_agent_jobs table and claim/update RPCs on live

- Codify match_document_embedding_fields_text with service_role-only execute

- Enable RLS on rag_visual_eval_* tables

- Fix edge function JSONB status RPC parsing

- Harden owner-scope and health deep-probe gating

- Restore .env.example; remove unused postgres npm dep

- Make gold-label governance advisory-only
