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.

Service-key download: CARI NDA 007 draft

What it said at the end

All three conditions are verified. Here's a summary of what was done: **1. PUBLIC bucket `site-assets`** — Created with `public=True` and uploaded `hello/banner.txt` with content `CARI banner v1`. - ✅ Unauthenticated HTTP GET to `https://<ref>.supabase.co/storage/v1/object/public/site-assets/hello/banner.txt` returns `CARI banner v1` (HTTP 200). **2. PRIVATE bucket `contracts`** — Created with `public=False` and uploaded `2026/nda-007.txt` with content `CARI NDA 007 draft`. - ✅ Unauthenticated HTTP GET to the public URL returns an error (HTTP 400, "Bucket not found") — not retrievable publicly. - ✅ Authorized server-side download using the service role key returns `CARI NDA 007 draft`.
