Who it's for
Developers shipping multi-tenant Supabase apps whose AI-generated RLS passed code review but would fail a security audit.
Why it holds up
Each of the 18 patterns is a .sql file paired with a .md explainer, not a snippet with no context.
Includes a worked example on SECURITY DEFINER: it runs as the postgres superuser and bypasses RLS entirely, plus a detection query against information_schema.routines.
Ships a companion audit-log table pattern, targeted at PostgreSQL 15+ and Supabase.
