What This Path Builds

A working sign-up, sign-in, sign-out, and callback flow.
A clear separation between browser and server clients.
Proof that RLS actually isolates user data.

Why This Topic Matters

Why generic tutorials often fall short

Many tutorials stop at 'the page logs in' and never really connect callback, middleware, session state, and database access.

Why This Topic Matters

What DepthPilot focuses on

The focus is a complete account chain and a clear sense of where it breaks, not just a copied UI form.

Why This Topic Matters

How the learner should verify it

The learner must validate user-scoped data access and guest boundaries after sign-in, not just a success message on the page.

Questions Learners Usually Ask

Does this fit Next.js 15?

Yes. The current project is already structured around Next.js 15 App Router and SSR patterns.

Why does RLS matter so much?

Because 'the user can log in' and 'the user's data is protected' are not the same thing.
