# Bead bf-dgn: Replace setup-r2.sh with setup-b2.sh

## Verification Summary

Task already completed in commit 65ea26f.

## Acceptance Criteria Verified ✅

1. ✅ **scripts/setup-r2.sh does not exist** - Confirmed via `ls` command
2. ✅ **scripts/setup-b2.sh exists, is executable, and runs without error** - Verified at 5590 bytes with `-rwxr-xr-x` permissions
3. ✅ **grep -r "setup-r2" scripts/ returns no hits** - Confirmed no references remain

## setup-b2.sh Features

The script successfully:
- Prints B2 bucket endpoint (reads from B2_ENDPOINT env var)
- Prints exact CNAME target for b2.aicodebattle.com → acb-data.s3.us-west-002.backblazeb2.com
- Verifies B2 credentials via curl to B2 API (when B2_KEY_ID/B2_APPLICATION_KEY are set)
- Is informational/verification-only (no destructive operations)
- Gracefully handles missing credentials with helpful setup instructions

## cloudflare-setup.sh Status

Already updated to reference B2 setup separately (lines 52-59) with no calls to setup-r2.sh.

## Test Results

Script executes successfully with and without B2 credentials:
- Without credentials: Shows helpful setup instructions
- With credentials: Performs API authentication verification
