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

Task complete. Everything is set up and verified. ## Summary **Buckets created** (via Supabase Storage API using the service role key): - `site-assets` — **public** - `contracts` — **private** **Objects uploaded** (exact byte content, no trailing newline): - `site-assets/hello/banner.txt` → `CARI banner v1` - `contracts/2026/nda-007.txt` → `CARI NDA 007 draft` **Verification results:** | Requirement | Result | |---|---| | `site-assets` object downloadable via plain unauthenticated HTTP GET (`/object/public/...`, no keys) | ✅ HTTP 200, returns `CARI banner v1` | | `contracts` object **not** retrievable via public URL pattern | ✅ HTTP 400 / "Bucket not found" (private bucket has no public route) | | `contracts` object readable via authorized service-key request (`/object/...` with service role bearer + apikey) | ✅ HTTP 200, returns `CARI NDA 007 draft` | Content integrity was confirmed with matching SHA-256 hashes for both objects against the expected exact strings.
