The role Supabase plays
Supabase commonly controls authentication, Postgres data, storage, edge functions, and row-level security. Its surrounding reliability depends on policies, JWT identity, generated queries, migrations, and client/service-key boundaries, so the visible error may originate outside the file the AI last changed.
Specific failure patterns to inspect
For Supabase RLS Fix, common causes include missing policy, incorrect auth UID relation, service key misuse, client-only filtering. Generated implementations also tend to omit defensive error handling, version checks, idempotency, or a safe difference between public configuration and private credentials.
A safer diagnostic sequence
Preserve the current branch and exact error. Then test with two isolated accounts; review policy predicates; identify every client query. Follow one test request across the interface, server or provider, and durable data rather than making several speculative code changes.
Repair boundaries
The repair should change the narrowest contract that is actually broken. Broader refactoring is justified only when duplicated ownership or an unsafe architecture would otherwise let the failure return.
What to avoid
Do not disable RLS in production or ship the service-role key to the browser. Do not upgrade the entire Supabase stack during a contained incident unless version incompatibility is the proven cause.
What a complete handoff includes
The handoff identifies the root cause, affected code or settings, safe test case, deployment note, and any remaining follow-up. The repaired behavior should be protected by a repeatable check.
