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 application user accounts on the Supabase project's GoTrue auth, fully headless: 1. **Created both users** via the Admin API (`POST /auth/v1/admin/users`) using the service-role key, with `email_confirm: true`. This marks each account's email as confirmed immediately (`email_confirmed_at` is set), so no confirmation email/click is needed. - `dana@cari.dev` → id `3d7ea60f-2005-495c-8421-16d97db69a8d` - `omar@cari.dev` → id `d09311ec-ebae-4cb9-a4c9-5214e50cc2f2` 2. **Verified password sign-in** against the project's public auth API (`POST /auth/v1/token?grant_type=password`, using only the anon key + email/password — exactly what a real client would do). Both returned a valid session: - Each response contained an `access_token`, `token_type: bearer`, `expires_in: 3600`, and the correct `user.email`, with no error. Both accounts can immediately sign in with email + password.
