    "test_cups_service_part3.py was a single 235-line class, so it split by method at test_port_ok_toner_exhausted: the no-port-status and hardware-error cases stay, the four healthy-port cases become TestQueryUsbViaCupsPortOk in test_cups_fallback_port_ok.py.",
    "Renamed the four part-numbered files after what they actually cover: test_cups_economode.py, test_cups_fallback_query.py, test_cups_ipp.py, plus the two new names.",
    "Import blocks trimmed per file to what each uses. No MOD constant changed; the source split in the previous commits already put every patched name in the module these files name."

  "risks": [
