CRITICAL BUG FIX: Chunk ID format is 'volumeId,fileKey' (e.g., '3,0307c52bab')
The problem:
- Log shows: CHUNKS: [3,0307c52bab]
- Script was splitting on comma: IFS=','
- Tried to download: '3' (404) and '0307c52bab' (404)
- Both failed!
The fix:
- Chunk ID is a SINGLE string with embedded comma
- Don't split it!
- Download directly: http://localhost:8080/3,0307c52bab
This should finally work!
