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 in place and verified. The schema is complete and the REST API serves all three tables without error. ## Summary I connected to the hosted Supabase Postgres instance and created the required schema in the `public` schema: **Tables created:** 1. **`authors`** — `id` uuid PK defaulting to `gen_random_uuid()`, `name` text NOT NULL, `email` text NOT NULL UNIQUE. 2. **`courses`** — `id` uuid PK with generated default, `author_id` uuid NOT NULL FK → `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(). 3. **`enrollments`** — `id` bigserial 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)` and `enrollments(student_email)` (both plain btree). **REST API verification:** An anonymous-key GET to `/rest/v1/courses` (and `/authors`, `/enrollments`) returns HTTP 200 with no error, confirming the tables are exposed by PostgREST. RLS was left off and anon/authenticated grants are already present, so reads succeed. All constraints (PKs, FK with ON DELETE CASCADE, the CHECK, and the composite UNIQUE) and indexes were verified directly against the catalog.
