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 three tables return HTTP 200 — the REST API is fully serving them. Here's a summary of what was done: ### Schema created in `public` schema: 1. **`authors`** — `id` (uuid PK, auto-generated via `gen_random_uuid()`), `name` (text, NOT NULL), `email` (text, NOT NULL, UNIQUE). 2. **`courses`** — `id` (uuid PK, auto-generated), `author_id` (uuid, NOT NULL, FK → `authors(id)`), `title` (text, NOT NULL), `price_cents` (integer, NOT NULL, `CHECK (>= 0)`), `published` (boolean, NOT NULL, default `false`), `created_at` (timestamptz, NOT NULL, default `now()`). 3. **`enrollments`** — `id` (bigint PK, generated identity), `course_id` (uuid, NOT NULL, FK → `courses(id)` ON DELETE CASCADE), `student_email` (text, NOT NULL), `enrolled_at` (timestamptz, NOT NULL, default `now()`), plus a `UNIQUE (course_id, student_email)` constraint. 4. **Indexes**: `idx_courses_author_id` on `courses(author_id)` and `idx_enrollments_student_email` on `enrollments(student_email)`. All three tables respond with 200 to anonymous-key requests via the Supabase REST API (`/rest/v1/...`).
