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 REST endpoints return **200 OK**. Here's a summary of what was done: ### Database schema created | Table | Key details | |---|---| | **`public.authors`** | `id uuid PK DEFAULT gen_random_uuid()`, `name text NOT NULL`, `email text NOT NULL UNIQUE` | | **`public.courses`** | `id uuid PK DEFAULT gen_random_uuid()`, `author_id uuid NOT NULL → 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()` | | **`public.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 created - `idx_courses_author_id` on `courses(author_id)` - `idx_enrollments_student` on `enrollments(student_email)` ### Permissions granted `SELECT, INSERT, UPDATE, DELETE` on all three tables (plus sequence usage) to the `anon`, `authenticated`, and `service_role` roles so PostgREST can serve them. ### Verification - `GET /rest/v1/authors` → **200** - `GET /rest/v1/courses` → **200** - `GET /rest/v1/enrollments` → **200**
