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

Done. Everything is set up and verified. ## Summary I created the database schema for the course platform in the `public` schema of the Supabase project using `psql` against the Postgres connection string: **Tables** - **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 FK → 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()`. - **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 (course_id, student_email)`. **Indexes** - Plain index `courses_author_id_idx` on `courses(author_id)`. - Plain index `enrollments_student_email_idx` on `enrollments(student_email)`. **Verification** - Inspected `information_schema.columns`, `pg_constraint`, and `pg_indexes` to confirm every column, default, CHECK, UNIQUE, and FK (with `ON DELETE CASCADE`) matches the spec. - Confirmed all three tables are exposed by the REST API: anonymous-key `GET /rest/v1/courses` (and `/authors`, `/enrollments`) all return **HTTP 200** with no errors. RLS is off on these tables, so the anon key can read them — which is why the REST requests succeed without error.
