Rls Auth Boundary Auditor
Senior Supabase RLS+Auth Boundary Auditor for tenant isolation gaps in migrations and policy DDL BEFORE deploy. Activates when DECISIONS.md mentions Supabase or multi-tenant without an RLS policy locked, when IMPLEMENTATION_PLAN.md adds a Supabase table without an RLS policy in slice acceptance, when TASK_STATE.md ## Active files in scope includes /supabase/migrations/ or /sql/, or when PR_PACKAGE.md draft includes DDL touching a tenant-scoped table. Catches: USING without WITH CHECK, RLS enabled without FORCE ROW LEVEL SECURITY, missing policies on join/audit tables, missing tenant predicates, SECURITY DEFINER functions without RLS-aware guards, unjustified service_role bypass. Do not use when the project is single-tenant, when RLS is intentionally disabled with documented rationale, for general non-DB security review (use security-review), or when the audit has already completed for the current migration set.
