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

All verification passed. Here's a summary of what was done: ## Summary Configured Supabase Storage in the `<ref>` project: **Buckets created** (via `POST /storage/v1/bucket` with service-role key): - `site-assets` — `public: true` - `contracts` — `public: false` **Objects uploaded** (via `POST /storage/v1/object/<bucket>/<path>` with service-role key, content-type `text/plain`, `--data-binary` to preserve exact bytes): - `site-assets/hello/banner.txt` → `CARI banner v1` (14 bytes, no trailing newline) - `contracts/2026/nda-007.txt` → `CARI NDA 007 draft` (18 bytes, no trailing newline) **Verification of access requirements:** | Check | Result | |---|---| | `GET /object/public/site-assets/hello/banner.txt` with **no headers at all** | ✅ HTTP 200, returns `CARI banner v1` | | `GET /object/site-assets/...` with anon key | ✅ HTTP 200 | | `GET /object/public/contracts/2026/nda-007.txt` | ❌ HTTP 400 `Bucket not found` (public URL pattern blocked because bucket is private) | | `GET /object/contracts/2026/nda-007.txt` with anon key | ❌ HTTP 400 `not_found` | | `GET /object/contracts/2026/nda-007.txt` with **service-role key** | ✅ HTTP 200, returns `CARI NDA 007 draft` | The site-assets object is freely downloadable via unauthenticated HTTP, and the contracts object is only reachable through authorized server-side calls using the service-role key (or a signed URL, since it's private).
