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

All done. Here's a summary of what was accomplished: **Tables created in `public` schema:** 1. **authors** — `id` (uuid PK, `gen_random_uuid()`), `name` (text NOT NULL), `email` (text NOT NULL, UNIQUE) 2. **courses** — `id` (uuid PK, `gen_random_uuid()`), `author_id` (uuid NOT NULL, FK → `authors(id)`), `title` (text NOT NULL), `price_cents` (integer NOT NULL, `CHECK (price_cents >= 0)`), `published` (boolean NOT NULL, default `false`), `created_at` (timestamptz NOT NULL, default `now()`) 3. **enrollments** — `id` (bigint, GENERATED ALWAYS AS IDENTITY PK), `course_id` (uuid NOT NULL, FK → `courses(id)` ON DELETE CASCADE), `student_email` (text NOT NULL), `enrolled_at` (timestamptz NOT NULL, default `now()`), `UNIQUE (course_id, student_email)` **Indexes:** - `courses_author_id_idx` on `courses(author_id)` - `enrollments_student_email_idx` on `enrollments(student_email)` **REST API exposure:** - Granted `USAGE` on schema `public` and `SELECT` on all three tables to the `anon` and `authenticated` roles (PostgREST's API roles). - Verified: anonymous-key requests to `/rest/v1/courses`, `/rest/v1/authors`, and `/rest/v1/enrollments` all return HTTP 200 (empty arrays, no errors).
