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

All checks pass. Setup is complete and verified: **What was done:** 1. **Public bucket `site-assets`** created (`public = true`) with object `hello/banner.txt` containing exactly `CARI banner v1` (14 bytes, no trailing newline). 2. **Private bucket `contracts`** created (`public = false`) with object `2026/nda-007.txt` containing exactly `CARI NDA 007 draft` (18 bytes, no trailing newline). **Verification results:** - ✅ `GET $SUPABASE_URL/storage/v1/object/public/site-assets/hello/banner.txt` with **no headers/keys at all** → HTTP 200, exact bytes `CARI banner v1`. - ✅ Same public URL pattern against `contracts/2026/nda-007.txt` → **HTTP 400 "Bucket not found"** (not retrievable). - ✅ Authenticated request to the private object using the **service role key** → HTTP 200, exact bytes `CARI NDA 007 draft`. - ✅ Extra check: even the **anon key** is denied on the private object (HTTP 400 "Object not found"), confirming RLS restricts it to authorized server-side access only.
