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 done. Summary of what was accomplished: **Schema created** (in `public`, via direct Postgres connection): - **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 REFERENCES 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()` - **enrollments** — `id bigint GENERATED ALWAYS AS IDENTITY PK`, `course_id uuid NOT NULL REFERENCES 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` (plain btree on `courses(author_id)`) and `enrollments_student_email_idx` (plain btree on `enrollments(student_email)`). **REST API**: Issued `NOTIFY pgrst, 'reload schema'` and verified with anonymous-key requests — `GET /rest/v1/authors`, `/rest/v1/courses`, and `/rest/v1/enrollments` all return **HTTP 200** (empty result sets, no errors). **Constraint verification**: Queried `pg_constraint` and `pg_indexes` to confirm every required constraint (PKs, FKs with cascade, CHECK, UNIQUEs) and both plain indexes exist exactly as specified.
