The screen locker skipped enforcement on 2026-07-03 without ever showing
a lock: a banked skip credit (earned from a prior 5+/week streak) was
consumed automatically with no confirmation and no visible log. Reworked
the whole reward mechanic instead of just gating it, since banking a
"skip a future workout" credit works against maximizing weekly workouts:
- Removed skip credits entirely (has_skip_credit/consume_skip_credit and
the confirmation dialog built to gate them). The only same-day skip
paths left are heat_skip and sick_day, both requiring a genuine reason.
- Extra workouts (5+/week) now bank shutdown-time-later hours for the
following week instead — comfort, not reduced enforcement. Reuses the
existing _adjust_shutdown_time_by and reset_to_base_if_new_day's
previously-discarded return value as the once-per-day gate.
- early_bird and sick_day no longer pollute workout_log.json. early_bird
is a same-day pending marker now stored in its own self-expiring,
HMAC-signed file; sick_day is sourced entirely from sick_history.json
(already the real source of truth). Fixes an accidental-safety gap
where "already took a sick day today" only halted startup by luck.
- Cleaned up 3 stale non-workout entries already in workout_log.json.

ScreenLocker now composes gatelock.GateRoot + gatelock.LockWindow for the
actual lock window instead of the inline WindowSetupMixin mechanics; the
verify/relaxed-day auxiliary windows (never the lock itself) stay as
plain Tk windows. The hand-copied _log_integrity.py is deleted in favor
of gatelock.log_integrity (the canonical, non-duplicated module). This
is the second of three migrations (diet_guard done, wake_alarm next).
Two deliberate behavior changes, both confirmed:
- dependencies = [] (pure stdlib) now includes gatelock, a documented
departure from the prior zero-deps stance.
- production grab upgraded from single-attempt-then-local-fallback to
diet_guard's retry-forever (robust to e.g. a fullscreen game holding
the grab).
Net hardening as a side effect: run()/close() now go through gatelock's
signal-safe lifecycle, so SIGTERM/SIGINT restore VT switching on every
exit path -- previously only a clean close() did, leaving VT switching
disabled if the service was killed mid-lock.

Adds a sick-day exemption flow with debt tracking so workout enforcement
can be skipped on declared sick days while preserving phone-verification
and shutdown invariants.
- New _sick_tracker module persists sick_history.json (days, debt, commitments).
- New _sick_dialog integrates declaration into the lock UI flow.
- _ui_flows.py and screen_lock.py consult tracker before enforcing workouts.
- gitignore sick_history.json (runtime state, like sick_day_state.json).
- 304 tests pass; 100% branch coverage on every screen_locker file.
