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

Everything is set up and verified. Here's a summary: ## What was done **1. PUBLIC bucket `site-assets`** - Created with `public=True` - Uploaded `hello/banner.txt` with content `CARI banner v1` (exactly) **2. PRIVATE bucket `contracts`** - Created with `public=False` - Uploaded `2026/nda-007.txt` with content `CARI NDA 007 draft` (exactly) ## Verification results | Test | Method | Expected | Actual | |------|--------|----------|--------| | **Public download** of `site-assets/hello/banner.txt` | Plain unauthenticated HTTP GET (no keys) | ✅ 200, content = `CARI banner v1` | ✅ 200, `CARI banner v1` | | **Public access blocked** for `contracts/2026/nda-007.txt` | Unauthenticated GET via public URL pattern | ❌ Should fail | ✅ **400** — "Bucket not found" (private buckets aren't served via the public path) | | **Authorized read** of `contracts/2026/nda-007.txt` | GET with `Authorization: Bearer <service_role_key>` via `/object/authenticated/` endpoint | ✅ 200, content = `CARI NDA 007 draft` | ✅ 200, `CARI NDA 007 draft` | All three requirements are satisfied: the public object is freely downloadable, the private object is not retrievable without authentication, and the private object is accessible via an authorized server-side request using the service role key.
