replica-backend

Reads replica/architecture.md. Writes migrations and server code, and keeps replica/backend.md (checklist below) up to date.

The rules

• Official, public APIs only, with the user's own keys. Never call the original app's private endpoints, never reuse its OAuth client, never proxy through it.
• The user creates accounts and keys. Claude never signs up for services, never types a password, card or live key. The user creates the Stripe, Supabase, Resend or Google Cloud project and puts keys in .env.local. Claude writes .env.example with every variable name and no values.
• Test mode first. Stripe test keys and test cards until replica-deploy.
