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. Set up file storage: 1) Create a PUBLIC bucket named site-assets and upload a text object at path hello/banner.txt whose content is exactly: CARI banner v1 2) Create a PRIVATE bucket named contracts and upload a text object at path 2026/nda-007.txt whose content is exactly: CARI NDA 007 draft When you are done: the site-assets object must be downloadable by a plain unauthenticated HTTP GET (no keys at all); the contracts object must NOT be retrievable through the public URL pattern, but must be readable in an authorized server-side request using the project's service key.

What it said at the end

Both objects contain the exact content required with no trailing newline or extra whitespace: - `site-assets/hello/banner.txt` → `CARI banner v1` - `contracts/2026/nda-007.txt` → `CARI NDA 007 draft` ## Summary I set up Supabase Storage as requested: 1. **`site-assets` bucket** — created as **public** (`"public": true`). Uploaded `hello/banner.txt` with content `CARI banner v1`. Verified it's fetchable via a plain unauthenticated `GET` to `https://<ref>.supabase.co/storage/v1/object/public/site-assets/hello/banner.txt` (returns HTTP 200, no keys/headers needed). 2. **`contracts` bucket** — created as **private** (`"public": false`). Uploaded `2026/nda-007.txt` with content `CARI NDA 007 draft`. Verified that: - The public URL pattern (`/storage/v1/object/public/contracts/2026/nda-007.txt`) returns `404 Bucket not found` with no keys — i.e., not retrievable via the public route. - An authorized server-side request using the service role key (`Authorization: Bearer <service_key>` + `apikey` header) against `/storage/v1/object/contracts/2026/nda-007.txt` succeeds (HTTP 200) and returns the correct content. All uploads were done via the Storage REST API using `curl` and the service role key, and both bucket configs and exact byte-for-byte content of both objects were verified.
