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 set up and verified. Here's the summary: | Bucket | Visibility | Path | Content | Public GET | Auth GET (service key) | |--------|-----------|------|---------|------------|------------------------| | `site-assets` | **Public** | `hello/banner.txt` | `CARI banner v1` | ✅ HTTP 200 | — | | `contracts` | **Private** | `2026/nda-007.txt` | `CARI NDA 007 draft` | ❌ HTTP 400 (bucket not found via public URL) | ✅ HTTP 200 | **What was done:** 1. Created the **`site-assets`** bucket (public) and uploaded `hello/banner.txt` — it's downloadable by anyone via `GET /storage/v1/object/public/site-assets/hello/banner.txt` with no authentication. 2. Created the **`contracts`** bucket (private) and uploaded `2026/nda-007.txt` — it's blocked from the public URL pattern (returns 400 / "Bucket not found"), but is fully readable with the service role key via `GET /storage/v1/object/contracts/2026/nda-007.txt` with an `Authorization: Bearer` header.
