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 requirements are verified and satisfied. Here's a summary of what I did: **Buckets created** (via the Storage REST API with the service-role key): - `site-assets` — **public** bucket - `contracts` — **private** bucket **Objects uploaded:** - `site-assets/hello/banner.txt` → content exactly `CARI banner v1` - `contracts/2026/nda-007.txt` → content exactly `CARI NDA 007 draft` **Verification of the access requirements:** 1. ✅ **Public object, no keys:** `GET …/storage/v1/object/public/site-assets/hello/banner.txt` returned `CARI banner v1` (HTTP 200) with *no* Authorization/apikey headers. 2. ✅ **Private object NOT retrievable via public URL pattern:** `GET …/storage/v1/object/public/contracts/2026/nda-007.txt` (unauthenticated) failed (HTTP 400 – the private bucket doesn't serve through the `/object/public/` path). 3. ✅ **Private object readable with service key:** `GET …/storage/v1/object/contracts/2026/nda-007.txt` with the service-role `Authorization`/`apikey` headers returned `CARI NDA 007 draft` (HTTP 200). The setup matches the task exactly: an open public asset, and a private contract that is inaccessible without authorization yet fully readable by authorized server-side (service-role) requests.
