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

Done. Summary of what was done: 1. Created two storage buckets in the Supabase project `<ref>` via the Storage REST API using the service role key: - `site-assets` with `public: true` - `contracts` with `public: false` 2. Uploaded the two text objects via `POST /storage/v1/object/{bucket}/{path}` using `--data-binary` so the bodies are exactly the requested strings with no trailing newline: - `site-assets/hello/banner.txt` → 14 bytes `CARI banner v1` - `contracts/2026/nda-007.txt` → 18 bytes `CARI NDA 007 draft` 3. Verified the three required behaviors with plain `curl`: - **Public bucket, no auth**: `GET .../storage/v1/object/public/site-assets/hello/banner.txt` → `200`, body `CARI banner v1` (14 bytes, no trailing newline). - **Private bucket, public-URL pattern, no auth**: `GET .../storage/v1/object/public/contracts/2026/nda-007.txt` → `400 Bucket not found`. Also tried the storage-key URL path without an Authorization header — same `400 Bucket not found`. The object is not retrievable through any unauthenticated route. - **Private bucket with service role key**: `GET .../storage/v1/object/contracts/2026/nda-007.txt` with `Authorization: Bearer <service_role>` and `apikey: <service_role>` → `200`, body `CARI NDA 007 draft` (18 bytes, no trailing newline).
