  "changes": [
    "test_consumables_part2.py split at TestCheckPageDelivery, which is exactly the MOD/MOD_PD boundary an earlier commit introduced. The two classes that needed MOD_PD move to test_page_delivery.py and use a plain MOD there, so the two-constant workaround dissolves rather than being carried forward: each file has one module under test again.",
    "test_consumables.py split at TestEstimateConsumableLife: the state file and CUPS page-log tests stay, the life estimate and replacement resets go to test_consumable_estimate.py.",
    "test_check_brother_printer.py split at TestMain: discovery and the network/USB mode selection stay, the CLI entry point and the reset flags go to test_check_brother_printer_main.py.",
    "Renamed test_consumables_part2.py to test_counter_scales.py and narrowed its docstring, which had claimed to cover dropped-page detection that now lives in test_page_delivery.py."

  "risks": [
    "Hand-trimmed import blocks remain the recurring risk in test splits; this pass hit it three times and the pass-count check caught it every time. A test that was already skipped would not be caught this way, but the package has none.",
    "Several test modules are now named after the private module they cover (_page_delivery, _pjl_io, _queue_fix). If a future split renames one of those source modules, the test file names go stale even though nothing breaks."

    "git revert the commit; the three originals return at 275, 272 and 273 lines and the three new modules disappear.",
    "After rollback, re-run the package suite and confirm it still reports 402 passed."
