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

Confirmed — the REST API, authenticated with only the anon key, returns exactly the five expected rows. ## Summary 1. **Created table** `public.products` with columns `sku text PRIMARY KEY`, `name text NOT NULL`, `price_cents integer NOT NULL`, `stock integer NOT NULL DEFAULT 0` via `psql` against `SUPABASE_DB_URL`. 2. **Loaded exactly 5 rows** (CARI-001 through CARI-005) as specified, using `TRUNCATE` + `INSERT` for idempotency. 3. **Enabled public read access**: - Enabled Row Level Security on the table. - Created policy `"Public read access"` allowing `SELECT` for `anon` and `authenticated` roles (`USING (true)`). - Granted `SELECT` privilege to `anon` and `authenticated`. - Sent `NOTIFY pgrst, 'reload schema'` to refresh PostgREST's schema cache. 4. **Verified** via `curl` against `$SUPABASE_URL/rest/v1/products?select=*&order=sku` using **only** the anon key (both as `apikey` header and `Authorization: Bearer`) — response returned all 5 rows with correct data, confirming the catalog is publicly readable as required.
