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

Done. Summary of what I did: 1. **Created the table** `public.products` with the required schema (`sku text PRIMARY KEY`, `name text NOT NULL`, `price_cents integer NOT NULL`, `stock integer NOT NULL DEFAULT 0`). 2. **Loaded the five rows** (CARI-001 through CARI-005) exactly as specified. 3. **Configured public access**: enabled Row Level Security and added a permissive `SELECT` policy for the `anon` and `authenticated` roles, plus an explicit `GRANT SELECT` so the catalog is readable without any privileged credentials. 4. **Verified the public read path**: a REST request to `${SUPABASE_URL}/rest/v1/products` using **only the anon key** (in both `apikey` and `Authorization: Bearer` headers) returned HTTP 200 and the full set of five rows. The catalog is now publicly readable via the anon-authenticated REST API.
