Auth and orgs
Supabase Auth is the user authority. Every app table resolves access through the user's single org.
Slice 1
Trust-first content starts with clean foundations.
This scaffold sets up the App Router shell, Supabase schema, RLS, auth context, entitlements, and product-credit primitives that later feature slices will build on.
Plan catalog
Free, Business, and internal plan versions live in Postgres so product access is not hard-coded.
Credit buckets
Article and research usage allocate against traceable product-credit buckets before generation starts.
