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 verified and working correctly. Here's a summary of what was done: **Buckets created:** 1. **`site-assets`** — PUBLIC bucket 2. **`contracts`** — PRIVATE bucket **Objects uploaded:** 1. `site-assets/hello/banner.txt` → content: `CARI banner v1` 2. `contracts/2026/nda-007.txt` → content: `CARI NDA 007 draft` **Access verification:** - ✅ **Public bucket object** (`site-assets/hello/banner.txt`): downloadable via plain unauthenticated HTTP GET → HTTP 200, content matches exactly. - ✅ **Private bucket object** (`contracts/2026/nda-007.txt`): unauthenticated access via the public URL pattern → HTTP 400 ("Bucket not found"), confirming it is NOT publicly accessible. - ✅ **Authorized access** using the service role key → HTTP 200, content matches exactly (`CARI NDA 007 draft`).
