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

Done. Both application user accounts are provisioned and proven working. ## Summary I provisioned the two requested auth accounts on the Supabase project (`<ref>`) and verified they can sign in headlessly: **Provisioning** — Used the GoTrue Admin API (`/auth/v1/admin/users`) with the **service role key** and set `email_confirm: true`, so both accounts were created with `email_confirmed_at` already stamped. No email confirmation / human click required. | Email | Password | User ID | Confirmed | |-------|----------|---------|-----------| | dana@cari.dev | Passw0rd-dana-91 | `55f67a22-1cf6-41fd-8034-d970911fcc7f` | ✅ | | omar@cari.dev | Passw0rd-omar-17 | `efe05592-fadb-4a29-b00b-5ce85a2d937e` | ✅ | **Proof of sign-in** — For each account I called the password grant endpoint (`/auth/v1/token?grant_type=password`) with the anon key and the supplied credentials, received a valid `access_token` (790 chars), then used that token against `/auth/v1/user`. Both returned a valid authenticated session with `aud: authenticated`, `role: authenticated`, the correct email, and updated `last_sign_in_at` — confirming the sessions are real and tied to the right accounts. Both accounts can sign in with email + password immediately, with no confirmation step.
