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. Here's what I did: 1. **Created the table** `public.products` with columns: `sku text PRIMARY KEY`, `name text NOT NULL`, `price_cents integer NOT NULL`, `stock integer NOT NULL DEFAULT 0`. 2. **Loaded exactly 5 rows**: CARI-001 through CARI-005 with the specified names, prices, and stock values. 3. **Enabled Row Level Security** and created a permissive SELECT policy (`USING (true)`) for the `anon` role, with `GRANT SELECT` granted to `anon`. This makes the catalog publicly readable via the REST API using only the anon key. 4. **Confirmed the read path works** — an HTTP request to the project's REST API (`/rest/v1/products`) authenticated with **only** the anon key (used for both `apikey` and `Authorization: Bearer`) successfully returned all 5 rows with the correct data: ```json [ {"sku":"CARI-001","name":"Anvil S","price_cents":1999,"stock":12}, {"sku":"CARI-002","name":"Anvil M","price_cents":2999,"stock":7}, {"sku":"CARI-003","name":"Anvil L","price_cents":4999,"stock":3}, {"sku":"CARI-004","name":"Rope 30m","price_cents":1250,"stock":40}, {"sku":"CARI-005","name":"Pulley","price_cents":780,"stock":0} ] ```
