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 three checks pass. Here's the summary: --- ### What was done **1. Created PUBLIC bucket `site-assets`** and uploaded `hello/banner.txt` with content `CARI banner v1`. - ✅ Public HTTP GET returns the content with no auth: `curl "$SUPABASE_URL/storage/v1/object/public/site-assets/hello/banner.txt"` → `CARI banner v1` (200) **2. Created PRIVATE bucket `contracts`** and uploaded `2026/nda-007.txt` with content `CARI NDA 007 draft`. - ❌ Public HTTP GET is denied (returns 400 `Bucket not found` — Supabase hides private buckets from the public URL pattern entirely). - ✅ Authorized GET with the service role key returns the content: `curl -H "Authorization: Bearer $SUPABASE_SERVICE_ROLE_KEY" "$SUPABASE_URL/storage/v1/object/contracts/2026/nda-007.txt"` → `CARI NDA 007 draft` (200)
