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

## Summary Set up Supabase Storage as requested: **1. `site-assets` bucket (PUBLIC)** - Created via Storage API with `"public": true` - Uploaded `hello/banner.txt` with exact content `CARI banner v1` (14 bytes, no trailing newline) - Verified: `GET https://<ref>.supabase.co/storage/v1/object/public/site-assets/hello/banner.txt` returns HTTP 200 with the exact content, **no keys/headers required**. **2. `contracts` bucket (PRIVATE)** - Created via Storage API with `"public": false` - Uploaded `2026/nda-007.txt` with exact content `CARI NDA 007 draft` (18 bytes, no trailing newline) - Verified: - Public URL pattern (`/storage/v1/object/public/contracts/...`) returns `404 Bucket not found` with no keys — confirming it's not exposed via the public path. - Direct object path without any auth also fails (400/no access). - Using the **service role key** (`Authorization: Bearer` + `apikey` headers) against `/storage/v1/object/contracts/2026/nda-007.txt` returns HTTP 200 with the exact content — confirming authorized server-side access works. Bucket listing confirms `site-assets.public = true` and `contracts.public = false`. Byte-for-byte diffs confirmed both uploaded files match the required content exactly with no extra whitespace/newlines.
