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 (Postgres connection string), SUPABASE_DB_PASSWORD.
Set up the database schema for a small course platform. Create exactly these tables in the public schema:
1) authors — id uuid primary key with a generated default, name text NOT NULL, email text NOT NULL and UNIQUE. 2) courses — id uuid primary key with a generated default, author_id uuid NOT NULL referencing authors(id), title text NOT NULL, price_cents integer NOT NULL with a CHECK constraint forbidding negative values, published boolean NOT NULL defaulting to false, created_at timestamptz NOT NULL defaulting to now(). 3) enrollments — id bigint identity (or bigserial) primary key, course_id uuid NOT NULL referencing courses(id) with ON DELETE CASCADE, student_email text NOT NULL, enrolled_at timestamptz NOT NULL defaulting to now(), and a UNIQUE constraint over (course_id, student_email).
Also create a plain index on courses(author_id) and a plain index on enrollments(student_email). When you are done, the new tables must be served by the project's REST API (an anonymous-key request to /rest/v1/courses must not error).

What it said at the end
I have successfully set up the database schema for your course platform and made sure the PostgREST API (used by Supabase) registered the tables.
Here's a brief summary of what was done:
1. **Created `authors` table**: Set up with a UUID primary key (generating random UUIDs by default), a `name` column, and a unique `email` column.
2. **Created `courses` table**: Set up with a UUID primary key, a foreign key `author_id` referencing the `authors` table, a `title` column, a `price_cents` column with a `CHECK (price_cents >= 0)` constraint, and default values for `published` (`false`) and `created_at` (`now()`).
3. **Created `enrollments` table**: Set up with a `bigint GENERATED BY DEFAULT AS IDENTITY` primary key, a foreign key `course_id` referencing `courses(id)` with `ON DELETE CASCADE`, a `student_email` column, and an `enrolled_at` column. A unique constraint was added over `(course_id, student_email)`.
4. **Created Indexes**: Added plain indexes for `courses(author_id)` and `enrollments(student_email)`.
5. **Reloaded PostgREST Schema Cache**: Called `NOTIFY pgrst, 'reload schema'` to ensure the REST API instantly discovers the new tables.
6. **Verified Access**: Made an anonymous-key GET request using `curl` against `/rest/v1/courses` which successfully returned an HTTP 200 (serving an empty JSON array because the table is currently empty).

A shell script executed against the live project and asserted on the state the agent left behind. No model judged another model.
