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

Created the requested Supabase schema: - `authors` - `courses` - `enrollments` - Indexes on `courses(author_id)` and `enrollments(student_email)` - Required primary keys, foreign keys, defaults, uniqueness, and nonnegative price constraint - Granted anonymous read access for REST API use - Reloaded the PostgREST schema cache Verified successfully: - `GET /rest/v1/courses` with the anonymous key returned HTTP `200` and `[]`.
