History
Krzysztof kuhy Rudnicki 6a7a7d8933 Queue behind stronger lockers, single-instance guard, fix budget-crash in fit check 
Root-caused the 2026-08-21 stuck-lock incident: a manual workout
unlocked correctly, but the mechanism behind "locked again seconds
later" was a stray workout-locker.service re-arm racing a second
process into building a competing lock window -- not a leetcode-guard
conflict as first suspected (its timer wasn't due until 13:00 that
day). Separately, diet_guard held the global grab for ~3 minutes
against a newly-arriving, higher-ranked screen_locker that morning,
which just retried and logged instead of making progress.

- _build_lock_window now calls gatelock.wait_for_turn before arming,
  so a stronger incumbent is queued behind instead of raced.
- New screen_locker/_instance.py (flock-based, mirrors
  leetcode_guard/diet_guard's own single-instance guards) stops a
  second process from ever building a competing window in the first
  place.
- Bumped to gatelock v0.7.1, which adds weaker-holder preemption
  (SIGTERM, reusing the holder's own clean close() path) so a lower-
  ranked incumbent can no longer block a stronger claim for minutes.
- Fixed a live crash in scripts/verify_screen_fits.py: it read the
  real log.json, so today's exhausted manual-workout budget (itself
  caused by the incident's duplicate entry) made the fit-check crash
  on an unset _mw_error_label. Points at a path that can never exist
  instead, so the measurement no longer depends on live data.
