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.

./run.sh failed outright with ModuleNotFoundError, and once running it
reported a sleeping printer as a critical paper jam. Both are fixed, plus
the defects found while verifying them against the real HL-1110.
Entry point: run.sh ran the script by path, so the absolute
python_pkg.* imports could not resolve. Resolve the repo root and pass
PYTHONPATH as a sudo argument, since sudo's env_reset strips an exported
one. __main__.py had the wrong import prefix and ran main() on import.
Status codes: the table claimed provenance from a "Brother PJL Technical
Reference" that does not appear to exist, and 23 of its 25 entries were
wrong. Rebuilt from the HP PJL Technical Reference Manual, Appendix D,
and verified against six states induced on real hardware (10001 READY,
10003 WARMING UP, 10023 PRINTING, 40000 SLEEP, 40021 TOP COVER OPEN,
41213 NO PAPER) - all six matched the reference, none matched the table.
40000 is SLEEP MODE, which the reference explicitly flags "not an error";
the real jam code 40022 was absent entirely. The inverse also bit: 10006
is TONER LOW, previously shown as a benign "Processing". Codes in no
reference are dropped and now report "Unknown status - check printer
display" rather than a confident wrong answer, and states we infer
ourselves no longer borrow PJL numbers to describe themselves.
Page counts: estimates came from the CUPS page log, which only sees jobs
CUPS logged and counts pages the printer never printed (it logged
total=50 for a job that printed 3). Take them from @PJL INFO PAGECOUNT
instead, migrating stored baselines onto the printer's scale once so the
reported percentages do not jump.
Reading status must not cost anything: a blocking open() hung forever
whenever the printer was unwell - precisely when a status report is
wanted - and the port-status probe stopped CUPS and reset the USB device,
destroying the in-flight job and then misreporting the damage as a
printer error. The fd is now non-blocking with deadline-bounded writes,
and the probe reads the same byte via the free usblp ioctl, skips
entirely while a job prints, and re-attaches the kernel driver.
Dropped pages: the HL-1110 silently discards pages whose 600dpi raster
exceeds its ~1MB memory, stays READY, and CUPS still calls the job
successful - so nothing anywhere reports the failure. Compare CUPS's
claim against the printer's counter between jobs and name the workaround
(lp -o Resolution=300dpi).
402 tests, 100% branch coverage.

Split diet_guard/_gatelock.py, wake_alarm/_alarm.py, and the
usage_report.py/_usage_report_parsing.py pair into focused
sub-modules so every Python file is <= 500 lines, satisfying
test_file_length.py. Install python-kasa into .venv (declared in
requirements but missing after the 3.13->3.14 venv upgrade),
fixing 8 failing smart_plug tests and restoring 100% coverage.
Also includes prior in-progress work from the working tree: the
wake_alarm Progress/View/Hardware field-grouping refactor,
brother_printer query module + tests, diet_guard foodbank/state/cli
updates, new shared coerce/logging_setup helpers, morning_routine
orchestrator tweaks, dwm window-manager config, gaming scripts, and
misc maintenance/digital-wellbeing script updates.
