Replays the SQL with real Postgres rules and returns, per table, what signed-out (anon) and signed-in (authenticated) users can SELECT/INSERT/UPDATE/DELETE (all rows, own rows, some rows, none, or denied for a missing grant), plus findings with severity and ready-to-run fix SQL: RLS off, policies written but RLS never enabled, using(true) writes, personal columns readable by anyone, views that bypass RLS, SECURITY DEFINER functions anyone can call, user_metadata in policies, public bucket listing, grants missing after the Oct 30 2026 default change. Also accepts the JSON produced by deadbolt_catalog_query for the live database. Deterministic; never connects to any database. Run it before telling a user their schema is safe. Up to 200,000 characters.",
