Client/server boundary

Review what can reach the browser and keep service-role operations server-side.

RLS behavior

Enable policies on public tables and test access with a real non-admin account.

Production path

Check domains, environment variables, monitoring, backups and payment webhooks.

Free runnable control proof

Inspect one RLS failure—and the policy fix.

The separate public fixture reproduces a synthetic cross-tenant read/write leak. Its broken branch reports 1 passed / 4 failed; its fixed branch reports 5 passed / 0 failed. The test file, harness, package and CI workflow are byte-identical; the fixed state adds db/policies.sql.

Broken: 1 passed / 4 failed Fixed: 5 passed / 0 failed

Open the public RLS fixture

Free and separate from the PDF. It is a synthetic PGlite control fixture for database-level policy behavior. It does not emulate Supabase Auth, PostgREST/Data API, network controls or production configuration, and it is not a penetration test, certification, or security guarantee.

Run it before your next deploy.
