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 are empty and anonymously reachable via REST (HTTP 200). ## Summary I created the course-platform schema on the hosted Supabase project `<ref>` and verified it end-to-end. **Tables created in `public`:** | Table | Key shape | |---|---| | `authors` | `id uuid PK` (default `gen_random_uuid()`), `name text NOT NULL`, `email text NOT NULL UNIQUE` | | `courses` | `id uuid PK` (default `gen_random_uuid()`), `author_id uuid NOT NULL` → `authors(id)`, `title text NOT NULL`, `price_cents integer NOT NULL` with **`CHECK (price_cents >= 0)`**, `published boolean NOT NULL DEFAULT false`, `created_at timestamptz NOT NULL DEFAULT now()` | | `enrollments` | `id bigint GENERATED ALWAYS AS IDENTITY PK`, `course_id uuid NOT NULL` → `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)` — both plain btree. **PostgREST exposure:** Sent `NOTIFY pgrst, 'reload schema'` immediately after the DDL so the new tables became visible without delay. Confirmed with the anonymous key: ``` GET /rest/v1/authors -> HTTP 200 GET /rest/v1/courses -> HTTP 200 ← required by the task GET /rest/v1/enrollments -> HTTP 200 ``` **Constraint spot-checks (all passed):** negative `price_cents` rejected by `courses_price_cents_check`; duplicate `email` rejected by `authors_email_key`; duplicate `(course_id, student_email)` rejected by `enrollments_course_email_unique`. Test rows were cleaned up; the database is left empty and ready for use.
