screen-locker/screen_locker/status_view.py

"""Read-only Tkinter status window plus a lightweight i3blocks summary CLI.

Opening or refreshing this window only ever reads files already on disk
(via ``_status_data.gather_status``). The live Warsaw temperature (see
``_section_temperature``) is fetched via
``_temperature.fetch_current_temp_with_status`` on open and on every refresh,
in its own background thread, bounded to ``_temperature.HARD_TIMEOUT_SECONDS``
— the same call the real locker's heat-skip check makes, so the window shows
what the lock actually sees. That fetch is display-only and never writes.

Two user-initiated buttons *do* write to ``workout_log.json`` (never a silent
log):

* "Check Phone" runs ``PhoneVerificationMixin._verify_phone_workout`` and, when
  that finds nothing, ``RunnerUpVerificationMixin._verify_runnerup_workout`` as
  a fallback — the same StrongLifts→RunnerUp chain the locked screen uses. On a
  verified workout it writes the entry and applies the shutdown reward via
  ``_apply_workout_credit`` (guarded against double-crediting on the same day),
  mirroring the submit/poll/``Future`` idiom of ``_ui_flows.py``.
* "Log Manual Workout" is a user-initiated, explicit evidence-form submission
  (see ``_manual_workout_dialog.ManualWorkoutDialogMixin``).
