2. Compliance Checklist

A) Idempotency Header

  • [x] All files contain -- This file can be run multiple times.
  • [x] Header matches the logic of the underlying SQL.

B) Idempotency Safety

  • [x] All CREATE TABLE use IF NOT EXISTS.
  • [x] All CREATE INDEX use IF NOT EXISTS.
  • [x] ALTER TABLE ADD COLUMN uses IF NOT EXISTS (PG 15+).
  • [x] RLS policies are wrapped in DO $$ blocks with IF NOT EXISTS checks on pg_policies (Ensures no "already exists" errors).

C) RLS Correctness

  • [x] bootstrap.sql is minimal and contains NO security logic.
  • [x] 20260216000006_rls_phase_1.sql explicitly calls ENABLE ROW LEVEL SECURITY.
  • [x] Policies implemented for: profiles, wallet, wallet_ledger, usage_logs.

D) Strict Model

  • [x] No Public Read: No policies allow anonymous or public access.
  • [x] Strict Ownership: All policies use auth.uid() = user_id (or ::text cast) ensuring users only see their own data.
  • [x] Service Role Access: Backend operations use the service_role key to bypass RLS for necessary cross-user updates (like ledger entries).

3. Final Verdict

SAFE TO RUN ALL FILES IN ORDER

The database layer is now hardened and ready for execution against the Supabase instance. Each script can be run individually or collectively without risk of data loss or schema corruption.
