Krzysztof kuhy Rudnicki a845cac883 Remove the flash challenge; revert the MethodChannel split that regressed NFC
Two things, one of them an undo of my own change.

The flash challenge is gone from the phone's rotation. It hides the code after
kDismissFlashSeconds, and on the phone that is unsolvable in practice: the ring
screen is reached by walking to another room and tapping a tag, so the code has
already vanished by the time the user is looking at it. Reported from the phone
as "invisible - impossible to actually do". Every challenge the alarm shows now
stays on screen until it is answered, and a test asserts next() never returns
one that hides itself. The constructor stays for the PC half's parity tests;
nothing routes to it.

The two-channel split is reverted. I introduced it to fix a tag reaching Kotlin
but not Dart, and pointed the push channel at the call channel — which broke
NFC *and* the step counter, both of which had been confirmed working on the
phone one build earlier. The user caught it: "they worked previously so your
changes regressed it". The split was a theory that was never shown to be
necessary; the single channel from 08b44b4 is restored unchanged.

Lesson worth keeping: when hardware has just confirmed a path works, the next
change should be the smallest possible delta on top of that exact state, not a
restructure bundled with a fix.

flutter test: 70 pass. dart analyze lib/ test/: clean.

wake_alarm

A phone-driven wake alarm for an always-on PC. The alarm time is whatever the companion phone app last synced (via the shared crdt_sync transport over a private GitHub repo); a per-minute systemd user timer fires at exactly that time, showing a fullscreen, challenge-dismissed alarm with escalating audio and optional TP-Link Tapo P110 smart-plug control.

Change the alarm on the phone at any hour and the PC follows within ~5 minutes. If the PC does happen to be powered down, a shutdown wrapper hibernates with rtcwake set to the same synced time, as a fallback.

Install

bash install.sh

This installs the package + dependencies into system Python's user site-packages (the systemd units run /usr/bin/python directly, not a venv — see CLAUDE.md), installs and enables the per-minute trigger timer, the systemd-sleep resume hook, the shutdown wrapper that hibernates with rtcwake as a fallback, and (optionally) python-kasa for smart-plug control.

Reading the phone's alarm needs a GitHub token with repo scope, at ~/.config/wake_alarm/sync.json as {"token": "..."}. If that file is absent, a sibling app's ~/.config/{diet_guard,screen_locker}/sync_token is used instead, so one token covers every app syncing through kuhyx/syncs.

Usage

python -m wake_alarm._alarm --demo     # test the alarm window (safe, closeable)
python -m wake_alarm._sync --show      # what alarm time the PC resolves
python -m wake_alarm._trigger --dry-run  # what the next tick would do
journalctl --user -fu wake-alarm-trigger.service  # watch it live

The alarm fires automatically once installed; no manual invocation is needed in normal operation.

Development

python -m venv .venv && .venv/bin/pip install -r requirements.txt
.venv/bin/pre-commit install && .venv/bin/pre-commit install --hook-type pre-push
.venv/bin/python -m pytest wake_alarm/tests/ --cov=wake_alarm --cov-branch --cov-fail-under=100
