- Added SCHEDULED_SKIPS_FILE constant pointing to scheduled_skips.json
- Added _is_scheduled_skip_today() method: reads JSON list of YYYY-MM-DD
strings, exits 0 if today's UTC date is found (skips lock entirely)
- _shutdown.py: changed rtcwake -m no -> -m disk so machine hibernates
immediately when scheduling morning alarm (bedroom use)
- Added tests/test_scheduled_skip.py with full branch coverage
- Added scheduled_skips.json with initial skip dates
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.
