Authentication can look complete while recovery or provider callbacks still fail.
A working dashboard does not prove cross-user isolation.
Supabase recommends RLS on every table in an exposed schema.
A service-role key can bypass RLS and must never reach the browser.
UI visibility is not an authorization boundary.
The success page alone is not proof that access and billing stay synchronized.
Public buckets and guessable object paths can expose private files.
Failure paths often reveal more than the happy path.
Preview configuration frequently differs from the real domain.
Authentication and customer flows often depend on email outside the app.
Users need accurate expectations and a way to resolve problems.
A launch needs ownership after the deploy succeeds.
A backup is only useful if it can be restored in time.
Accessibility failures can block customers from completing essential tasks.
Why this matters
Cross-user access, exposed secrets, broken authorization, and unsafe payment access cannot be averaged away.
A Yes should mean a repeatable test with an expected result—not that the feature appeared to work once.
Authentication, policies, dependencies, payments, hosting, and privacy changes can invalidate earlier results.
