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 three tables exist and are reachable via the REST API with the anonymous key. What I did: - Connected to the Supabase Postgres instance via `SUPABASE_DB_URL` and ran a single DDL block that: - Created `public.authors` with `id uuid primary key default gen_random_uuid()`, `name text not null`, `email text not null unique`. - Created `public.courses` with `id uuid primary key default gen_random_uuid()`, `author_id uuid not null` referencing `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()`. - Created `public.enrollments` with `id bigint generated always as identity primary key`, `course_id uuid not null` referencing `courses(id) on delete cascade`, `student_email text not null`, `enrolled_at timestamptz not null default now()`, plus `unique (course_id, student_email)`. - Created plain indexes `courses_author_id_idx` on `courses(author_id)` and `enrollments_student_email_idx` on `enrollments(student_email)`. - Verified the schema with `\d+` for each table — all columns, defaults, FKs, CHECK, UNIQUE, and indexes match the spec. - Verified REST exposure with an anonymous-key `GET` to `/rest/v1/courses` (HTTP 200, body `[]`), and the same for `/rest/v1/authors` and `/rest/v1/enrollments`. Note: I deliberately did not add Row Level Security policies or grants. The tables are reachable via PostgREST because Supabase's `anon`/`authenticated` roles default to having the necessary privileges on tables in the `public` schema (and PostgREST auto-discovers new tables). If you'd like the tables to be restricted to authenticated users, that would be a follow-up step.
