Supabase RLS Leak Demo

¿Qué es Supabase RLS Leak Demo?

A tiny, runnable Supabase/Postgres security fixture that proves a policy can look correct and still leak rows across tenants. The same test suite runs red on the broken policy and green after the one-file fix. Start with npm ci && npm test—no Docker, cloud project, credentials, or production data required. Built for founders and developers who want evidence before shipping multi-tenant apps.
