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

Storage setup completed and verified: - **Public bucket:** `site-assets` - Object: `hello/banner.txt` - Content: `CARI banner v1` - Unauthenticated public GET: **HTTP 200** - **Private bucket:** `contracts` - Object: `2026/nda-007.txt` - Content: `CARI NDA 007 draft` - Public URL access: **blocked** - Service-key authorized access: **HTTP 200**
