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, SUPABASE_DB_PASSWORD. Create a table public.products with columns: sku text primary key, name text NOT NULL, price_cents integer NOT NULL, stock integer NOT NULL default 0. Load exactly these five rows: CARI-001, Anvil S, 1999, 12 CARI-002, Anvil M, 2999, 7 CARI-003, Anvil L, 4999, 3 CARI-004, Rope 30m, 1250, 40 CARI-005, Pulley, 780, 0 The catalog is public: when you are done, an HTTP request to the project's REST API authenticated with ONLY the anon key must return these rows. Confirm that read path works before finishing.

What it said at the end

Created `public.products` with the requested schema and loaded exactly the five catalog rows. Configured public read access through: - Grants for the `anon` role - Row-level security policy allowing public `SELECT` Verified the REST API using only the anon key. It returned exactly the five expected rows successfully.

How it was graded
