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

## Summary I provisioned both application user accounts on the Supabase project's Auth system, fully headless: 1. **Created both users via the Admin API** (`POST /auth/v1/admin/users` using the service-role key), with `email_confirm: true` so no confirmation email/click was needed: - `dana@cari.dev` / `Passw0rd-dana-91` → user id `ff9faf13-55ba-4905-9a29-b8e8e398f2c3` - `omar@cari.dev` / `Passw0rd-omar-17` → user id `2de15bf0-7036-4df9-af1d-f2eb54575fd8` 2. **Proved password sign-in works** for both, by calling the real client auth endpoint (`POST /auth/v1/token?grant_type=password`) with the anon key, exactly as a front-end app would: - Both requests returned **HTTP 200** with a full session: `access_token` (valid JWT, `role: authenticated`, `amr: password`), `refresh_token`, and `expires_in: 3600`. - Decoded the JWTs to confirm `email`, `sub` (user id), and `aal1`/password auth method all match. 3. **Cross-checked against the database directly** (`auth.users` table via `psql`) confirming both accounts have `email_confirmed_at` set and an `encrypted_password` present — i.e., they are fully activated, password-based accounts with no pending confirmation step. Both `dana@cari.dev` and `omar@cari.dev` can now sign in immediately with their passwords and receive a valid session/access token, with zero human-in-the-loop steps required.
