a12e696 turned CI red two ways, both missed locally because the suite was
run for the brother_printer package alone while CI runs everything in a
random order.
The repo caps Python files at 500 lines and cups_service.py had reached
659. Rather than cut it arbitrarily, extract consumable life tracking -
page counters, replacement baselines, the scale migration, dropped-page
detection - into consumables.py. The seam is real: none of it depends on
CUPS service control, and cups_service needs only estimate_consumable_life
for its fallback query, so the dependency runs one way. The test files are
split along the same seams.
test_main_entry passed or failed depending on execution order: runpy warns
when the target module is already in sys.modules, a sibling test imports
it, and pytest is configured with filterwarnings=error. Drop the module
before running it so the test no longer depends on who ran first.
Structural only; no behaviour change. 692 tests, 100% branch coverage.
