test_cups_service.py 390 -> 172 (usblp port status to _port), part2 261 -> 115 (status mapping and discovery out), part3 260 -> 105 (the four healthy-port cases out). part3 was one 235-line class, so it split by method rather than by class. The four part-numbered files are renamed for what they cover; three of them now name _cups_fallback, matching where the code moved earlier. The first run after the part2 split reported 400, not 402: the moved classes needed subprocess and get_status_info that my hand-written import block had dropped. Fixed, and the count is 402 again.
