Retire the PC's waking role; keep the trigger

Browse Source 
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.

## What this does ## What this does
A wake alarm: on alarm days (`ALARM_DAYS` in `_constants.py` — currently **The phone is the alarm.** `phone_app/` arms and rings it and gates the

then opens a fullscreen Tk window that must be dismissed (with a typed challenge — see
`_challenges.py`), plays audio through every real sink, and optionally
toggles a TP-Link Tapo P110 smart plug via `python-kasa`.
## Scheduling — a per-minute timer, with hibernate as the fallback The PC's waking role was deleted on 2026-08-30: no alarm window, no audio
escalation, no smart plug, no curtains, no `rtcwake`, no `shutdown` wrapper,
no sleep hook. Making the PC wake someone reliably cost more than it returned.
Everything about it is in git history; do not reintroduce a piece of it
without saying why the phone cannot do that job.
The PC is **always on**. The alarm time comes from the phone, which can change ## The dismiss sequence (phone)
it at any hour, so nothing about the schedule may be baked in ahead of time.
**Primary path — `wake-alarm-trigger.timer`:** ```
tag 1 -> 25 steps + 2 min -> tag 2 -> 3 challenges
```
1. The timer ticks every minute (`OnCalendar=*:*:00`, `Persistent=true`) and Owned by `phone_app/lib/services/dismiss_gate.dart`. **Strict order, and every
runs `python -m wake_alarm._trigger` — a short, stateless check-and-fire. stage latches** — an unknown or out-of-order tag is ignored, never a reset.
2. `_trigger` resolves the alarm via `_sync.get_alarm()`, builds today's fire `room_proof.dart` answers only "did this one check pass just now"; the
instant in **local** time, and fires iff `now` is in ordering lives in the gate. Keep it that way: the previous version smeared the
`[fire_time, fire_time + TRIGGER_CATCHUP_MINUTES)`. The catch-up window is decision across `setState` calls and had a real bug where a wrong tap after
what makes a suspended or just-booted machine still fire. passing sent the user back to the start.
3. Firing = `systemctl --user start morning-routine.service`. **Never**
`wake-alarm.service` directly — see the orchestrator section below.
Starting an already-active unit is a no-op, so an alarm on screen needs no
extra dedupe state; the `was_alarm_dismissed_today()` /
`was_workout_logged_today()` gates cover the rest.
A timer, not a resident daemon: each tick is a fresh process, so there is no - **Two *distinct* tags.** The same id in both slots is refused at

suspend/resume. entire point. Stored as a JSON list under `roomProof.nfcTagIds`; a legacy
single `roomProof.nfcTagId` migrates into slot 1.
- **Steps are unchanged** (`requiredSteps = 25`, `requiredElapsed = 2 min`),
and are counted from ring start, *not* re-baselined at tag 1. Consequence:
walking to tag 1 already banks the steps, so only the elapsed floor really
binds — which is why the steps stage auto-polls instead of offering a button.
- **Answers are cumulative, not consecutive.** A wrong one costs the attempt
and nothing else.
- **The bypass skips the tags, never the walk.** After
`DismissGate.bypassAfter` (5 min), or immediately when NFC is off or fewer
than two distinct tags are registered, the tag stages are skipped and the
count rises to 6. Jumping straight to the challenges would let someone lie in
bed for five minutes and answer questions without standing up — weaker than
the gate this replaced. Do not "simplify" it into that.
- **No challenge may hide its prompt.** The memorise-then-hide kind was
deleted, not merely unrouted: the ring screen is reached by walking in from
another room.
**Fallback path — hibernate (only when the PC really is powered down):** `RingScreen` takes an injectable `clock`. `Stopwatch` reads the wall clock,
which `tester.pump()` does not advance, so without that seam no widget test
can reach the two-minute floor or the five-minute bypass.
`shutdown-wrapper.sh` (installed to `/usr/local/bin/shutdown`, shadowing More, including everything that is a hard crash or a silent no-ring:
`/usr/bin/shutdown` via PATH order) still intercepts shutdown/poweroff, reads **`DOCS-phone-alarm.md`**.
the same synced alarm, and sets `rtcwake`. `sleep-hook.sh` (in
`/usr/lib/systemd/system-sleep/`) fires on resume (`$1 == post`) and starts
`morning-routine.service`. This is now a backstop, not the main mechanism.
If you change `WAKE_AFTER_HOURS` in `_constants.py`, you must also update the ## Scheduling — a per-minute timer
duplicate constant in `shutdown-wrapper.sh` (`WAKE_AFTER_HOURS=8`) — they are
not wired together, by design (the shell wrapper has no Python runtime
available at the point it intercepts `shutdown`).
**The wrapper no longer talks to the network or handles a token.** It reads `wake-alarm-trigger.timer` ticks every minute (`OnCalendar=*:*:00`,
`~/.config/wake_alarm/alarm_cache.json` — the cache `_sync.py` already `Persistent=true`) and runs `python -m wake_alarm._trigger` — a short,
refreshes every minute — and falls back to `WAKE_AFTER_HOURS` if that file is stateless check-and-fire. It resolves the alarm via `_sync.get_alarm()`, builds
absent, malformed, or more than 2 days old. This removed the duplicated token today's fire instant in **local** time, and fires iff `now` is in
search order (`read_sync_token()` used to mirror `SYNC_CONFIG_FILE` / `[fire_time, fire_time + TRIGGER_CATCHUP_MINUTES)`. Firing means
`SYNC_TOKEN_FALLBACK_FILES`), and it is what makes the wrapper survive the `systemctl --user start morning-routine.service`, which runs the workout lock.
move to Firebase unchanged: an ID token expires in about an hour, and a shell
script at shutdown time has no safe way to refresh one. The only coupling left
is the cache's `{"hour","minute","fetched_at"}` shape — keep the reader in the
wrapper in step with `_write_cache()` in `_sync.py`.
## `wake-alarm.service` must never auto-start **The once-per-day latch is load-bearing.** After a successful start,
`_trigger` writes `save_trigger_fired()` and `_skip_reason` gates on
`was_trigger_fired_today()`. Without it the routine restarts on every tick for
the rest of the 60-minute window: the unit is `Type=simple`, so a start while
it runs is a no-op, but the moment the workout lock finishes the next tick
relaunches it on top of the user. This latch replaced the alarm's own
dismissal record when `_alarm.py` was deleted — deleting one without adding the
other is a silent regression, and that is exactly the trap.
`wake-alarm.service` deliberately has **no `[Install]` section** and nothing `Persistent=true` plus the 60-minute window is also what replaced the deleted

workout-logged but has **no time gate**, so a
`WantedBy=graphical-session.target` there fires the alarm at *login* time on
any alarm day — which is every day now that the machine no longer reboots into
the alarm. `install.sh` explicitly runs `systemctl --user disable
wake-alarm.service` to clear the stale symlink from older installs.
The unit survives only as a manual test handle. Do not "fix" its missing
auto-start.

## The phone rings on its own
`phone_app/` is no longer a time picker: it arms and rings its own alarm
(items 1/4) via five Kotlin files behind **one** MethodChannel, gating
dismissal behind a room proof plus a challenge. **Never replace that with a
pub plugin, and never move the ring off `STREAM_ALARM`.** Everything that is
a hard crash or a silent no-ring is in **`DOCS-phone-alarm.md`**.
## Module map
`_alarm.py` owns the window and the dismiss flow and nothing else. The full
map of which module answers which question, the HDMI-silence root cause, and
the timing constants that must not collide are in **`DOCS-architecture.md`**.
Read it before changing the escalation or the failsafe.
## Cross-repo coupling — not a bug
`_constants.py`'s `WORKOUT_LOG_FILE` points at
`~/screen-locker/screen_locker/workout_log.json` — a file owned by the
separate, already-standalone `screen-locker` repo
(https://github.com/kuhyx/screen-locker). This is intentional: the alarm
reads whether today's workout was already logged by screen-locker to decide
whether the morning routine should also lock the workout screen. If this
path ever raises `ModuleNotFoundError`-style confusion, the bug is almost
certainly in the **orchestrator** (`morning_routine` in testsAndMisc), not
here — see the next section.
## The morning_routine orchestrator lives elsewhere ## The morning_routine orchestrator lives elsewhere
`morning_routine._orchestrator` (in `testsAndMisc/python_pkg/morning_routine/`) `morning_routine._orchestrator` (in `testsAndMisc/python_pkg/morning_routine/`)

reference must be updated in the same change** — this exact mistake
(orchestrator left pointing at `python_pkg.screen_locker.screen_lock` after
screen-locker's extraction on 2026-05-28) caused a month-long silent
production failure where the alarm fired and dismissed correctly but the
workout lock crashed with `ModuleNotFoundError` on every run. Once both
`wake_alarm` and `screen_locker` are pip-installed system-wide, the
orchestrator needs no `PYTHONPATH`/`cwd` plumbing — plain
`subprocess.run([sys.executable, "-m", module, "--production"])` resolves
both.
## Production dependency installation — read this before adding any dependency **When this package's module paths change, the orchestrator must change in the
same commit.** Leaving it pointing at a module that no longer exists caused a
month-long silent production failure once already (2026-05-28, orchestrator
still on `python_pkg.screen_locker.screen_lock` after screen-locker's
extraction): the alarm fired and dismissed correctly while the workout lock
crashed with `ModuleNotFoundError` on every run.

`/usr/bin/python3 -c "import <new_dep>"`, not just the dev venv, before
considering a dependency change done. `uninstall.sh`, never `rm -rf` on the repo. `/usr/local/bin/shutdown` is
root-owned and shadows `/usr/bin/shutdown`; deleting the repo leaves it in
place, 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 breaks a live feature in
another repo with no error message anywhere.
## Operational gotchas ## Operational gotchas
- **`python-kasa` is optional at runtime** (`_smart_plug.py` catches
`ImportError` and disables smart-plug control with a warning log), but it
*is* a hard dependency for this repo's own tooling (mypy/pylint/tests need
it importable) — see `pyproject.toml`/`requirements.txt`.
- **The `wave` module needs special pylint handling.** `_audio.py` opens WAV
files in write mode; pylint's stdlib stub infers the read-mode overload and
wrongly flags `setnchannels`/`setsampwidth`/`setframerate`/`writeframes` as
missing. See the `generated-members` list in `pyproject.toml`'s
`[tool.pylint.typecheck]` — don't remove it if pylint starts complaining
about `wave.Wave_write`.
- **`wake_state.json` is runtime state, not tracked.** It holds the - **`wake_state.json` is runtime state, not tracked.** It holds the

- **`WAKE_STATE_FILE` is redirected in `tests/conftest.py`, not per-file.**
`_trigger` writes it now, and the trigger tests never redirected it — a
per-file redirect is exactly the kind that gets forgotten when a new writer
appears, and the failure is silent: a green suite that quietly stamped the
live state file.

# wake_alarm architecture
Reference for the module layout after the 2026-08-26 split, and the two
failure modes that motivated it.
## Where behaviour lives
`_alarm.py` owns the window and the dismiss flow and nothing else. When looking
for behaviour, start here:
| Question | Module |
|---|---|
| Should the alarm run at all today? | `_gating` (no time gate — that is `_trigger`) |
| What should it sound like right now? | `_escalation` (pure), driven by `_beep_loop` |
| Why did it go quiet? | `_escalation` — the failsafe at `FAILSAFE_SILENCE_SECONDS` |
| Why is there no sound on HDMI? | `_sinks` + `_reactivate` (see below) |
| Challenge presentation / rounds | `_rounds`, `_countdown`, `_dismiss_view` |
| Recurring timers | `_alarm_timers` (a mixin; they reschedule via `root.after`) |
| Screen flash | `_screen_flash` (~1.3 Hz, deliberately under the 3 Hz threshold) |
| Startup hardware | `_startup` (display, brightness, plug + pre-roll) |
| Structured logs | `_logging_setup`, `_log_sink`, `_log_dedupe`, `_correlation` |
### The audio failure this fixed
`_activate_all_outputs()` ran **once**, at startup, and `_parse_profile_line`
drops any profile reporting `available: no`. At wake time the monitor has not
finished its HDMI handshake, so the profile is skipped — and while a card's
profile is `off` its sink **does not exist**, so `_play_on_all_sinks`'s
per-cycle re-enumeration can never find it. `_reactivate` re-runs activation on
a decaying schedule and logs the enumerated sink list each pass.
A **powered-off speaker is not detectable from software** — the analog sink is
present and `IDLE` either way. That is a hardware problem; see
`DOCS-speaker-recommendation.md`.
### Timing constants that must not collide
`FAILSAFE_SILENCE_SECONDS` (300) silences **audio only**; the lock, challenge
and workout gate persist. Two invariants are locked in by tests in
`test_escalation.py`, because breaking either silently guts the alarm:
- `PHASE_MEDIUM_END * 60 < FAILSAFE_SILENCE_SECONDS` — otherwise the escalation
never leaves its softest rung before going quiet.
- `ESCAPE_OFFER_AFTER_SECONDS` (900) `> FAILSAFE_SILENCE_SECONDS` — otherwise
the escape hatch appears exactly as the alarm stops being annoying.

# Curtains: what to buy, and what the code already does
Item 5 of the hardening plan — "sun curtains open automatically on alarm
trigger". The **software is shipped and wired**; there is no hardware yet. The
alarm already calls `open_curtains()` on its startup path, next to
`turn_on_plug()`, and the default driver logs what it would have done.
So buying a motor is a config file, not a code change:
```bash
cat > ~/.config/wake_alarm/curtains.json <<'JSON'
{"driver": "noop"}
JSON
```
Absent file, malformed file, or an unknown driver name all fall back to the
no-op with a WARNING. A driver that throws is caught and the alarm rings on —
a jammed motor must never be a reason not to be woken.
## Why curtains are worth having at all
The audio failsafe silences the alarm after `FAILSAFE_SILENCE_SECONDS`
(300 s). Daylight is the one wake cue that keeps working after that, and the
only one that does not depend on a speaker, a sink, or a working HDMI
handshake — the exact chain that made this alarm silent in the first place.
It is also the cue that keeps working while you are in the other room solving
the phone's challenge.
## Adding a driver
`_curtains.py` has a two-method `CurtainDriver` protocol (`open`, `close`) and
a `_DRIVERS` registry. A new motor is one class plus one registry entry.
Three rules, all of which the existing no-op and `_smart_plug.py` follow:
1. **Import the dependency inside the factory, guarded.** The service runs
`/usr/bin/python`, not a venv, so a library that failed to install must
degrade to the no-op rather than kill the alarm process.
2. **Return, never raise.** `open_curtains()` catches, but a driver that
blocks forever cannot be caught — give every network call a timeout, the
way `TAPO_TIMEOUT_SECONDS` does.
3. **Never block the alarm.** The call is on the startup path, ahead of the
first beep.
## Hardware options
Nothing here is bought or tested — this is a shortlist, not a recommendation
from use. Ordered by how well each fits the constraints above.
### 1. Retrofit chain/rod motor (best fit)
A motor that clamps onto the existing rail, so no new curtains and no
landlord conversation. Look for:
- **Local control** — an HTTP or MQTT endpoint on the LAN. A cloud-only
device makes a 07:00 wake dependent on someone else's uptime, which is
precisely the dependency `_sync.py` already works hard to bound.
- **A physical manual override**, so a dead motor is not a dark room.
- **Mains power, not battery.** A battery that dies quietly gives you a
failure with no symptom until the morning it matters.
Zigbee/Z-Wave models need a hub; a Wi-Fi model with a local API needs none
and is the simpler driver to write.
### 2. Tapo/Kasa-driven mains switch (cheapest path)
If a curtain motor with a hard switch is already in place, a second smart plug
would work through `python-kasa`, which this repo already depends on. Cheapest
by far, but it only works for a motor that opens on power-up — most do not.
### 3. Nothing (the current state)
Genuinely fine. The no-op driver is not a stub awaiting replacement; it is the
correct behaviour for a machine with no motor, and it keeps the log event and
the call site real so nothing has to be rediscovered later.
## What is deliberately not here
- **No cloud integrations.** See the local-control point above.
- **No scheduling of its own.** The alarm decides when morning is; a curtain
motor with its own timer would be a second source of truth, and the whole
design of this repo is that the phone is the only one.
- **No "close at night" automation.** `CurtainDriver.close()` exists so a
driver has both ends implemented, but nothing calls it yet. Closing belongs
to the night lockdown (item 13), not to the alarm.

# Speaker recommendation — bedroom wake alarm
Item 7 of the alarm-hardening work. **Prose only; no code changes here.**
## Why the software cannot solve this
A powered-off speaker is **undetectable from software**. Measured on this
machine: the analog sink is present and `IDLE` whether or not the amplifier has
mains power.
```
$ pactl list short sinks
61 alsa_output.pci-0000_0d_00.6.analog-stereo PipeWire s32le 2ch 48000Hz IDLE
```
Nothing in `_list_real_sinks()` can distinguish "playing to speakers" from
"playing to an amp that is switched off". Designing detection here would be
shipping a placebo. The fix is hardware plus the smart plug that is *already*
integrated.
## The deciding spec is the power switch, not the LED
`_alarm.py` already calls `turn_on_plug()` when the alarm fires and
`turn_off_plug()` from `on_close()` — which runs on every exit path including
SIGTERM. So the "cut mains overnight, restore at alarm time" architecture is
already implemented; it simply has no plug configured yet
(`~/.config/wake_alarm/tapo.json` does not exist).
That makes one criterion pass/fail, ahead of everything else:
> **GATE — the speaker must come back ready to pass audio when mains returns,**
> with no button press and no standby state.
A **latching mechanical** switch (rear rocker, or a volume pot with a click-off
detent) holds its position through a mains cut, so the unit re-energises in the
state it was left in. A **momentary / soft-touch / microcontroller** button has
no mechanical memory and boots into whatever firmware defaults to — usually
standby. That is disqualifying.
**Rule of thumb: a remote control in the box = disqualified.** Anything with a
remote has a standby microcontroller.
## Verified findings (official manuals / vendor FAQs only)
| Model | Switch | LED | Verdict |
|---|---|---|---|
| **Edifier R1280T** ~299–309 zł | Rear latching rocker, **no remote** | Blue, front | ✅ **Top pick** |
| Edifier R1280DB / R1700BT / R1855DB | Has remote → soft standby | — | ❌ see below |
| **Mackie CR3-X** ~ | Rear rocker **+** front click-off pot, no standby | White logo ring, **cannot be defeated** | ⚠️ gate-passes, light fails |
| **M-Audio BX3** | Front click-detent pot (no rear switch) | Front LED | ✅ runner-up |
| **JBL 104** | Rear latching | Front ring around volume knob | ⚠️ auto-standby after 19 min |
| PreSonus Eris E3.5 (non-BT) | Front latching On/Off | Solid blue | ⚠️ ok, but see BT note |
| PreSonus Eris **BT** models | — | Red in standby | ❌ 15-min standby, **up to 30 s wake delay** |
| **SVEN SPS-702** ~239 zł | Rear mains rocker, no remote, analogue pots | Single pinhole | ✅ budget pick |
| Creative Pebble Pro | RGB button cycles to Off | persistence unverified | ⚠️ unverified |
### The Edifier trap, worth stating explicitly
Edifier's own support article (R1280DB/DBS standby): powering down with the
remote activates **standby** — the LED goes off but the physical switch stays
on, and *"the only way to wake the speakers is to use the same remote power
button."* A mains cycle will **not** clear that state. So any Edifier with a
remote breaks the smart-plug architecture. The plain **R1280T has no remote**,
which is exactly why it is the right pick.
### Disqualified on wake latency
PreSonus Eris BT: standby after 15 minutes, and waking costs *"delay up to half
a minute until audio playback is heard."* An alarm that starts half a minute
late is a broken alarm. JBL 104 has the same class of problem (19-minute
standby), though it can be disabled via a headphone-jack toggle sequence.
## Recommendation
1. **Edifier R1280T (~299–309 zł)** — passes the gate (rear latching rocker, no
remote, no standby state to get stuck in), loud enough at 42 W RMS, analogue
volume pot so the level survives a power cycle. Its blue front LED is the
one drawback → cover it with a LED-blackout sticker ("LEDim", biohac.pl, or
any Allegro *naklejki blokujące światło LED*). Cheap, reversible, no warranty
impact.
2. **SVEN SPS-702 (~239 zł)** — budget alternative, same topology (rear mains
rocker, no remote, analogue pots), 40 W RMS, single pinhole LED.
**Avoid** anything with a remote, and avoid Mackie CR3-X for a *bedroom* (its
white logo ring cannot be turned off while powered — vendor FAQ confirms).
## Analog, not USB
Keep the speakers on **analog 3.5 mm**, not USB. A USB speaker disappears from
PipeWire when its mains is cut and re-enumerates on restore, reintroducing
exactly the `auto_null`-only sink race that caused the 2026-07-11 silent alarm.
An analog sink stays present regardless of the speaker's power state.
## Required code change (tracked separately)
`_alarm.py`'s `main()` runs `turn_on_plug()` immediately before
`WakeAlarm(...).run()` — **zero lead time**. An amplifier's soft-start / mute
relay typically delays output 1–5 s after mains is applied, which would swallow
the opening of the alarm. Add a configurable pre-roll delay between plug-on and
the first beep.

never reverts:
```
tag 1 -> 25 steps + 2 min -> tag 2 -> 3 challenges
```
The two tags must be *distinct* and live in different rooms; the same id in
both slots is refused at registration. Answers are cumulative, so a wrong one
costs the attempt and nothing else.
**One fallback, deliberately narrow.** After 5 minutes of ringing — or
immediately if NFC is off or fewer than two tags are registered — the two *tag*
stages are skipped and the challenge count rises to 6. The walk is never
skipped. Without a hatch of some kind, a dead tag at 06:00 leaves an alarm that
cannot be switched off at all.
Details, and the things that are a hard crash or a silent no-ring:
**`DOCS-phone-alarm.md`**.
## The PC half
A per-minute systemd user timer (`wake-alarm-trigger.timer`) reads the alarm
the phone published through the shared `crdt_sync` transport, and at that time
starts `morning-routine.service`, which runs the workout lock. It records a
once-per-day latch so the rest of the catch-up window does not restart it.
That is all it does. There is no alarm window, no audio, no smart plug, no
`rtcwake`, and no `shutdown` wrapper.

`morning_routine`, and production deployment gotchas.

"""Assert the alarm's screens fit a 1366x768 display.
The alarm ``place``s a centred frame, and a ``place``d frame takes its
*requested* size: when it is taller than the screen the parent shears equal
amounts off the top **and** the bottom -- which here means losing "WAKE UP!"
and the answer entry at once, on a screen whose entire purpose is to be
answered before it will stop. There is no scrollbar and nothing to indicate
anything is missing, so "it fits" is the only thing keeping it usable.
Runs the real builders against a real (throwaway) X display, because widget
heights come from the font engine and nothing short of rendering can answer
this honestly:
cd ~/wake-alarm && python3 -m scripts.verify_screen_fits
Run as a *module*, not a path: ``-m`` puts the repo root on
``sys.path`` so ``wake_alarm`` resolves from the checkout. Running it as a
path only works where the package happens to be pip-installed, which is
why it passed locally and died in CI.

#!/bin/bash
# Wrapper for /usr/bin/shutdown that redirects to rtcwake -m disk on alarm
# nights (every day of the week). This ensures that both the automated
# systemd timer AND manual "shutdown now" hibernate correctly so the PC
# wakes for the morning alarm.
#
# Install to /usr/local/bin/shutdown (takes priority over /usr/bin/shutdown
# because /usr/local/bin appears first in PATH).
#
# This is the FALLBACK path, for the rare night the PC is actually powered
# down. The primary path is wake-alarm-trigger.timer, which ticks once a
# minute on the always-on machine and fires at the phone's alarm time without
# any rtcwake involvement (see wake_alarm/_trigger.py).
#
# Wake time is read from ~/.config/wake_alarm/alarm_cache.json, the on-disk
# cache that wake-alarm-trigger.timer refreshes every minute from the alarm
# the phone app pushes. Falls back to WAKE_AFTER_HOURS if that cache is
# missing or unusable.
#
# Deliberately a *local file read*, with no network call and no credentials.
# This script runs as /usr/local/bin/shutdown, at the one moment the machine
# is going down; a remote fetch there can block on a dying network, and under
# Firebase it could not work at all, because an ID token lasts about an hour
# and refreshing one is beyond what a shell script should be doing with a
# secret. The Python side already holds the credentials and already keeps this
# cache fresh, so the backend it syncs against is now invisible here: this
# wrapper needs no changes when GitHub is retired.
#
# The trade-off is bounded and acceptable: a cache older than the trigger's
# refresh interval still reflects the last alarm the phone published, and the
# alarm changes far more rarely than once a minute. MAX_CACHE_AGE_SECONDS
# below only rejects a cache so old it suggests the trigger has been dead for
# days, in which case the fixed fallback is the safer answer.

functions because each of these reschedules itself through ``root.after`` and
needs the alarm's own view and progress state -- the same shape as
``AlarmTimersMixin``.
Two independent flashes live here and must not be confused:
* the **challenge** countdown (:meth:`_start_flash_countdown`) shows a code for
``DISMISS_FLASH_SECONDS`` and then hides it, so the user has to memorise it;
* the **background** pulse (:meth:`_flash_step`) alternates the window colour
forever, so the screen keeps demanding attention.
Both stop the moment ``_active`` goes false, which is what keeps a dismissed
alarm from repainting a window that is on its way out.

"""The fire-time record that makes a hard power-off survivable.
The real gap behind item 2 is not the power button itself -- it is that
nothing on disk ever says *"an alarm is ringing right now and was never
dismissed"*. ``wake_state.json`` is written only on **dismissal**, so cutting
power mid-alarm leaves no trace at all: the next boot sees an undismissed day
that looks exactly like a day the alarm had not reached yet, and the catch-up
window has long since closed. Holding the power button therefore *works*, and
that is what this module removes.
So the alarm writes a record the moment it starts ringing, and clears it when
the ring genuinely ends. ``_trigger`` re-fires on a record still marked
``ringing``, ignoring the catch-up window.
**Deliberately no date field.** ``_state.py`` keys its record by a UTC date,
and ``screen_locker/_wake_state.py`` mirrors that helper to read the very same
file from a different repo -- so the UTC basis there is load-bearing and is not
touched. Rather than add a second date key on a different basis, this record
carries only ``fired_at`` as an aware ISO timestamp, and freshness is an
elapsed-time comparison. Timezone-agnostic by construction, so the local
midnight question never arises.
**Bounded, because an unfinished session is not self-clearing.** If the alarm
process dies before dismissal -- Tk cannot open a display, a crash at startup
-- nothing ever runs ``on_close()`` to mark the session finished, and an
unbounded re-fire rule would restart the alarm every single minute forever.
The record is therefore honoured only within ``REFIRE_MAX_AGE_SECONDS`` of
``fired_at``, and the ordinary day / dismissed / workout gates still apply on
top of it.
Signed with :mod:`gatelock.log_integrity`, exactly like ``_state.py``, so the
record cannot simply be edited to say ``dismissed``.

"""Open the curtains when the alarm fires, if any hardware is configured.
Item 5. There is **no curtain hardware yet**, so the default driver is a
logging no-op: it records what it would have done and returns. That is the
whole point of shipping this now rather than waiting for a motor — the alarm
sequence gains its call site, the JSONL log gains its event, and buying
hardware later is a config file, not a code change.
Deliberately shaped like :mod:`wake_alarm._smart_plug`, which solves the same
problem (optional hardware that must never delay or break the alarm):
* absent or malformed config means "no curtains", never an error;
* every failure is caught and logged, because a stuck motor must not stop the
alarm from ringing;
* a driver's dependency is import-guarded, so an uninstalled library degrades
to the no-op instead of killing the alarm process.

"""Hold a logind inhibitor so one power-button press cannot kill the alarm.
Item 2 of the hardening plan. Today a short press on the power button runs
``HandlePowerKey=poweroff`` and the alarm is gone in one tap -- less effort
than typing a single challenge round.
Verified on this host before writing any of this:
$ grep PowerKey /etc/systemd/logind.conf
#HandlePowerKey=poweroff
#HandlePowerKeyLongPress=ignore
#PowerKeyIgnoreInhibited=no
``PowerKeyIgnoreInhibited=no`` is the default and is in force, which is exactly
what makes a ``--mode=block`` inhibitor suppress the short press. So no
``logind.conf`` edit is needed, and none is made: a drop-in would change the
machine permanently, while an inhibitor is scoped to the alarm's lifetime.
**What this cannot block, stated plainly:** a ~4 second firmware hold cuts
power below the operating system, and so does the PSU switch. Neither is
defeatable from userspace. The durable defence against those is the fire-time
session record in :mod:`wake_alarm._alarm_session` -- the alarm re-fires on the
next boot rather than being escaped -- not this inhibitor.
**Why a bounded ``sleep`` and not ``sleep infinity``:** the inhibitor is a
child process. If the alarm dies without running ``on_close()`` -- a crash, a
SIGKILL -- an orphaned blocker holding ``handle-power-key`` would leave the
power button dead until the next reboot, which is a far worse failure than the
one being fixed. The child therefore exits on its own after
``INHIBIT_MAX_SECONDS`` even if nobody ever releases it, and a stale one from a
previous run is killed at startup -- by pid, via ``/proc``, never by matching a
command-line substring (see :func:`_is_our_inhibitor` for why).

unstubbed run really spawns ``systemd-inhibit`` (blocking the machine's power
button for as long as the test process lives) and really writes the
*production* ``alarm_session.json``, which the next real trigger tick would
then act on. All three are stubbed here and re-patched explicitly by the tests
that assert the wiring.
The escape hatch adds a third: ``WakeAlarm.__init__`` builds its tracker over
the real ``ESCAPE_HISTORY_FILE``, so an unpatched run both reads a *production*
