The PC no longer wakes anyone -- the phone does. This deletes the alarm window, the audio escalation, the sink/reactivation machinery, the power-key inhibitor, the escape hatch, the curtains, the smart plug, the brightness and DDC/CI control, the hibernate path (shutdown wrapper + rtcwake + sleep hook) and the challenge set: 30 modules, 34 test files, ~5k lines. What stays is the part that still earns its keep: the per-minute trigger reads the alarm the phone published and starts morning-routine.service, so the workout lock still runs at the right time. THE ONE LOAD-BEARING BEHAVIOUR CHANGE. Deleting _alarm.py orphaned the only writer of wake_state.json, and _trigger gated on it via was_alarm_dismissed_today(). With that gone -- and was_workout_logged_today() already permanently False, since WORKOUT_LOG_FILE does not exist -- both gates would have been dead and the routine restarted on every tick for the rest of the 60-minute catch-up window. The unit is Type=simple, so a start while it runs is a no-op, but the moment the workout lock finished the next tick would relaunch it on top of the user. So _trigger now writes its own once-per-day latch (save_trigger_fired / was_trigger_fired_today) and gates on that. Collapsing the catch-up window instead was rejected: that window is the entire reason a suspended or just-booted machine still fires. It also replaces the deleted sleep hook, via Persistent=true. _trigger also imported should_refire from _alarm_session, which was on the delete list. Since start_session lived only in _alarm.py, no session record is ever written again and the branch was unreachable, not merely unused. WAKE_STATE_FILE is now redirected in tests/conftest.py rather than per-file. The trigger tests never redirected it, because until this commit nothing on that path wrote anything -- and a per-file redirect is exactly the kind that gets forgotten when a new writer appears, with a silent failure: a green suite that quietly stamped the live state file. Verified by mtime that it did not. Cross-repo, same change: morning_routine._orchestrator loses its alarm leg and its --with-alarm flag. Leaving an orchestrator pointing at a deleted module caused a month-long silent failure once already. uninstall.sh is new, and matters more than it looks. /usr/local/bin/shutdown is root-owned and shadows /usr/bin/shutdown; deleting this repo would leave it in place, and with the alarm cache gone it falls through to rtcwake + hibernate -- so "shutdown now" would silently stop being a poweroff, every day, forever. /etc/sudoers.d/wake-alarm is deliberately NOT removed: screen-locker's own _wake_alarm.py still needs passwordless rtcwake. 159 tests pass at 100% branch coverage; all 26 pre-commit hooks green. Verified by running it: _sync --show and _trigger --dry-run both resolve.

# Remove the PC's waking machinery.

# Usage:
|

# bash uninstall.sh # remove everything this repo installed
|

# bash uninstall.sh --retired-only # remove only the retired waking pieces

#
|
|
# WHY THIS SCRIPT EXISTS, AND WHY `rm -rf` ON THE REPO IS NOT ENOUGH:
|
|
# `/usr/local/bin/shutdown` is root-owned and shadows `/usr/bin/shutdown` via
|
|
# PATH order. Deleting the repo does NOT remove it, and with the alarm cache
|
|
# gone it falls through to `sudo rtcwake ... ; exec systemctl hibernate` --
|
|
# so `shutdown now` would silently stop being a poweroff, every day, forever.
|
|
#
|
|
# `/etc/sudoers.d/wake-alarm` is deliberately LEFT IN PLACE even by a full
|
|
# uninstall: screen-locker's own _wake_alarm.py:_schedule_rtcwake still shells
|
|
# out to `sudo rtcwake`, and removing the entry here would break a live feature
|
|
# in another repo with no error message anywhere.
