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

Confirmed: `site-assets` is `public: true`, `contracts` is `public: false`. ## Summary Using the Supabase Storage REST API with the service-role key, I: 1. **Created bucket `site-assets`** (`public: true`) and uploaded `hello/banner.txt` containing exactly `CARI banner v1`. 2. **Created bucket `contracts`** (`public: false`) and uploaded `2026/nda-007.txt` containing exactly `CARI NDA 007 draft`. **Verification results:** - `GET {SUPABASE_URL}/storage/v1/object/public/site-assets/hello/banner.txt` with **no credentials** → `200 OK`, body = `CARI banner v1` ✅ - Same public URL pattern against `contracts/2026/nda-007.txt` → `404` (bucket not public, blocked) ✅ - Anon-key and fully unauthenticated requests to the contracts object path → `404`, blocked ✅ - `GET {SUPABASE_URL}/storage/v1/object/contracts/2026/nda-007.txt` with `Authorization: Bearer $SUPABASE_SERVICE_ROLE_KEY` → `200 OK`, body = `CARI NDA 007 draft` ✅ Both storage buckets and objects are set up and access-controlled exactly per the requirements.
