The dismiss gate was an OR — NFC tag *or* QR *or* (25 steps + 2 min) —
followed by one challenge. QR never worked at ring time (no scanner
package, no CAMERA permission, `onQrScanned` had no caller), so the real
bar was "walk 25 steps, wait 2 minutes, answer one question" and the NFC
tag was already fully bypassable.
It is now a strict, latched sequence owned by `DismissGate`:
tag 1 -> 25 steps + 2 min -> tag 2 -> 3 challenges
Every stage is required, in that order, and a stage once passed never
reverts. That last part also fixes a real bug: `_onNfcTag` and `_trySteps`
both assigned the room-proof result straight onto `_inRoom`, so a wrong
tag tapped after the gate had passed sent the user back to the start.
Two *distinct* tags are required; the same id in both slots is refused at
registration, since one tag satisfying both stages removes the walk that
is the whole point. The existing single-tag registration migrates into
slot 1 rather than being stranded.
Answers are cumulative, not consecutive: a wrong one costs the attempt and
nothing else.
The bypass is the only fallback and is deliberately narrow. After 5 minutes
of ringing, or immediately when NFC is off or fewer than two distinct tags
are registered, the two *tag* stages are skipped and the count rises to 6.
The walk is never skipped — jumping straight to the challenges would let
someone lie in bed for five minutes and answer questions without standing
up, which is weaker than the gate this replaces. Without some such hatch a
dead tag at 06:00 leaves an alarm that cannot be switched off at all.
Also deletes the `flash` challenge outright, along with the now-orphaned
`generateCode`/`kDismissCodeLength`/`_dismissChars`. It was the only kind
that removed its prompt from the screen, which is unsolvable for someone
who has just walked in from another room.
The ring screen takes an injectable clock: `Stopwatch` reads the wall
clock, which `tester.pump()` does not advance, so without that seam no
widget test could reach the two-minute floor or the five-minute bypass.
Verified on the Pixel 6a: the existing tag migrated into slot 1 and both
rows render. 102 Dart tests pass; analyzer 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
