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 fully provisioned and verified. ## Summary I provisioned two application user accounts on the Supabase project's auth, fully headless: 1. **Created both users** via the GoTrue Admin API (`POST /auth/v1/admin/users`) using the service role key, with `email_confirm: true`. This marks the email as confirmed at creation time — no confirmation email/click is required, so they can sign in immediately. - `dana@cari.dev` → id `15e9c846-8db1-4046-b7e2-ce5887287b2f` - `omar@cari.dev` → id `be3daac0-2719-451c-a625-4d34ee05a51b` - Both show a populated `email_confirmed_at`. 2. **Proved sign-in works** for each via the public password grant endpoint (`POST /auth/v1/token?grant_type=password`) using only the anon key + email/password (the real client-facing flow). Both returned a valid bearer session: - `dana@cari.dev` → access_token (790 chars), expires_in 3600 - `omar@cari.dev` → access_token (790 chars), expires_in 3600 Both accounts can immediately authenticate with email + password.
