On 2026-09-19 the phone was powered off after the bathroom tag and nothing on the PC noticed: every finished session was published and nothing read it. Now wake-alarm distils the phone's morning into an HMAC-signed ~/.local/state/wake_alarm/morning_session.json (wake-alarm-session.timer, 07:00-11:00 every 2 min) that screen-locker and leetcode-guard read to defer their locks -- provisionally until min(start + 90 min, 09:30) while the session is live, until 11:00 once it completed inside that cutoff, and not at all for a session finished later (the phone switched on at noon completes the legs then; that must un-lock nothing). The phone publishes the session at start as well as at finish (current_session, cleared with the finish stamp), so the PC can tell "started, not finished" from "never started". A required 1-5 energy tap joins the weigh-in and ships as latest_energy with a PC reader mirroring _weight (the shared half is _field_reader). Also fixes the vmbox harness, red since the 2026-09-11 home-tidy: the guest tree lives at ~/wake-alarm, and the INSTALL-OK grep matched vm's echo of the command line. Takes Flutter 3.47.5.

# 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.
