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

Done. Here's a summary of what I set up: ## Storage Setup Summary **1. Public bucket `site-assets`** (created with `public: true`) - Uploaded object at `hello/banner.txt` with exact content `CARI banner v1` (14 bytes). **2. Private bucket `contracts`** (created with `public: false`) - Uploaded object at `2026/nda-007.txt` with exact content `CARI NDA 007 draft` (18 bytes). **Verification results:** - ✅ **Public object** — Downloadable by a plain unauthenticated HTTP GET with no keys: `GET .../storage/v1/object/public/site-assets/hello/banner.txt` returned `HTTP 200` with exact content `CARI banner v1`. - ✅ **Private object** — NOT retrievable via the public URL pattern: `GET .../storage/v1/object/public/contracts/...` returns `HTTP 400 "Bucket not found"` (private buckets aren't exposed under the `/public/` path). - ✅ **Private object** — Readable via an authorized server-side request using the service role key: `GET .../storage/v1/object/contracts/2026/nda-007.txt` with `Authorization: Bearer <service_role>` returned `HTTP 200` with exact content `CARI NDA 007 draft`. All operations were performed through the Supabase Storage REST API using the `SUPABASE_SERVICE_ROLE_KEY`, and all requirements were confirmed with live HTTP requests.
