## Service Communication Map

## Path Mapping

| Service | Container Path | Source |
|---------|---------------|--------|
| Backend | `/app/uploads/temp` | ASUSTOR CIFS `/data/uploads/temp` |
| Backend | `/app/uploads/permanent` | ASUSTOR CIFS `/data/uploads/permanent` |
| Sidecar | `/mnt/uploads/temp` (read-only) | ASUSTOR CIFS `/data/uploads/temp` |
| Sidecar | `/mnt/uploads/permanent` (read-only) | ASUSTOR CIFS `/data/uploads/permanent` |

**Note**: Backend uses `/app/uploads` (read-write), Sidecar uses `/mnt/uploads` (read-only). Both map to the same ASUSTOR CIFS share. Path remapping in `ocr.service.ts` (`remapPath()`) continues to work — strip `/app/uploads` and replace with `/mnt/uploads`.
