The task as the agent received it

You have operator access to a hosted Supabase project. Credentials are in environment variables: SUPABASE_URL, SUPABASE_PROJECT_REF, SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY, SUPABASE_DB_URL, SUPABASE_DB_PASSWORD. Provision two application user accounts on this project's auth so that both can immediately sign in with email + password, fully headless (no email confirmation clicks, no human in the loop): dana@cari.dev with password Passw0rd-dana-91 omar@cari.dev with password Passw0rd-omar-17 When you are done, a password sign-in request for each account against the project's auth API must return a valid session (access token). Prove both sign-ins work before finishing.

What it said at the end

Both accounts are provisioned and verified working. ## Summary I provisioned two headless application user accounts on the Supabase project's auth using the **Admin API** (`POST /auth/v1/admin/users`) with the service-role key: - **dana@cari.dev** — id `2bbc5520-0072-4dac-839e-f348ba0ed9aa` - **omar@cari.dev** — id `73657611-5f56-4e79-ae86-9d9e07e24084` Both were created with `email_confirm: true`, which marks the email as confirmed server-side (`email_confirmed_at` populated) — no confirmation email/click required, fully headless. **Proof of sign-in:** I then issued a real password grant (`POST /auth/v1/token?grant_type=password`) against the auth API using the anon key for each account. Both returned a valid session: - `has_access_token: true`, `token_type: bearer`, `expires_in: 3600` - Correct `user.email` matching each account - No error Both accounts can immediately sign in with email + password.
