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

Everything is set up and verified. Here's a summary of what was done: ## Database Schema Created Three tables were created in the `public` schema via direct Postgres connection: 1. **`authors`** - `id` — uuid PK with `gen_random_uuid()` default - `name` — text, NOT NULL - `email` — text, NOT NULL, UNIQUE 2. **`courses`** - `id` — uuid PK with `gen_random_uuid()` default - `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 constraint on `(course_id, student_email)` ## Indexes - `idx_courses_author_id` on `courses(author_id)` - `idx_enrollments_student_email` on `enrollments(student_email)` ## REST API Verification All three tables are served by the project's REST API — anonymous-key GET requests to `/rest/v1/authors`, `/rest/v1/courses`, and `/rest/v1/enrollments` all return HTTP 200 with empty arrays. No RLS policies were needed since Supabase's default `anon` role has read access to tables without RLS enabled.
