Every locker screen, the status window and the credit toast now show glyphs (screen_locker/_glyphs.py) and numbers, coloured by state. Sentences that carried a reason (verifier message, sync diagnosis, sick refusal, form rejection) go to the log at warning instead. New pre-commit hook text-free runs scripts/verify_text_free.py.

"""Live Warsaw-temperature background check mixin for ``StatusWindow``.
|
|
|
|
Fetches the same reading the real locker's heat-skip check would see
|
|
(``_temperature.fetch_current_temp_with_status``), in a background thread,
|
|
bounded to ``_temperature.HARD_TIMEOUT_SECONDS`` — display-only, never
|
|
writes to ``log.json``. Host class must provide:
|
|
|
|
- ``self.root`` — the Tk root, for ``root.after`` polling.
|
|
- ``self.temperature_fetcher`` — injected fetch callable (tests override it).
|
|
- ``self._temp_future`` / ``self._temp_result`` — state slots, initialized
|
|
by the host's ``__init__``.
|
|
- ``self._last_snapshot`` — the most recently rendered ``StatusSnapshot``.
|
|
- ``self.render(snapshot)`` — full redraw, called after a result resolves.
