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

I have successfully provisioned both application user accounts on your Supabase project's auth system. Here is what I did: 1. Used the Supabase **Admin API** (`/auth/v1/admin/users`) with the `SUPABASE_SERVICE_ROLE_KEY` to directly create the two users. 2. Passed `"email_confirm": true` during user creation to ensure their emails were pre-verified, skipping the need for manual email verification. 3. Verified both accounts' login functionality by sending a password sign-in request (`/auth/v1/token?grant_type=password`) with the `SUPABASE_ANON_KEY`. Both accounts successfully returned an independent `access_token`, confirming they can immediately sign in with their respective credentials. The task is complete.
