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

The read path is confirmed working. Here's a summary of what I did: 1. **Created the table** `public.products` with columns: `sku` (text PK), `name` (text NOT NULL), `price_cents` (integer NOT NULL), `stock` (integer NOT NULL default 0). 2. **Loaded exactly five rows** via SQL INSERT — CARI-001 through CARI-005 with the specified names, prices, and stock values. 3. **Enabled Row Level Security** on the table and created a SELECT policy (`"public read access"`) granting read access to both `anon` and `authenticated` roles with `USING (true)`. 4. **Confirmed the public read path** — an HTTP GET to the project's REST API (`/rest/v1/products`) authenticated with **only the anon key** returns all five rows in the expected format.
