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: HTTP 200 with exactly 5 rows returned via the anon-key-only REST request. ## Summary 1. **Connected** to the Supabase Postgres instance via `psql` using `SUPABASE_DB_URL`. 2. **Created** `public.products` with columns `sku text PRIMARY KEY`, `name text NOT NULL`, `price_cents integer NOT NULL`, `stock integer NOT NULL DEFAULT 0`. 3. **Loaded** the exact 5 rows (CARI-001…CARI-005) via an idempotent upsert (`ON CONFLICT DO UPDATE`). 4. **Made the catalog public**: - Enabled Row Level Security on the table. - Added a `SELECT`-only policy for `anon` and `authenticated` roles (`USING (true)`). - Granted `USAGE` on schema `public` and `SELECT` on `public.products` to `anon`/`authenticated`. - Sent a `NOTIFY pgrst, 'reload schema'` to refresh PostgREST's schema cache. 5. **Verified** by querying the DB directly (5 rows correct) and then hitting `GET $SUPABASE_URL/rest/v1/products` with **only** the `apikey`/`Authorization: Bearer` headers set to the anon key — got HTTP 200 and exactly the 5 expected rows back. The read path is confirmed working with anon-only credentials; task complete.
