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.
