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

Everything is confirmed working. ## Summary 1. **Created table** `public.products` via `psql` connected to `SUPABASE_DB_URL`, with columns: - `sku text PRIMARY KEY` - `name text NOT NULL` - `price_cents integer NOT NULL` - `stock integer NOT NULL DEFAULT 0` 2. **Loaded exactly the 5 specified rows** (CARI-001 through CARI-005) using an idempotent `INSERT ... ON CONFLICT DO UPDATE`. 3. **Enabled public read access**: - Turned on Row Level Security (`ALTER TABLE ... ENABLE ROW LEVEL SECURITY`) - Created a policy `"Public read access"` allowing `SELECT` for the `anon` and `authenticated` roles - Granted `SELECT` privilege on the table to `anon` and `authenticated` 4. **Verified the read path** by hitting the REST API (`${SUPABASE_URL}/rest/v1/products`) using **only** the anon key (no service role key) — confirmed HTTP 200 and all 5 rows returned with correct data, matching the required dataset exactly.
