Add the diet_guard package: a screen-locking meal-logging gate that fires on 4-hour slots (08/12/16/20) and records calories/macros, persisting an autocompleting food bank. - Trigger fix: the systemd timer fires at session start (Persistent=true) before lightdm has written ~/.Xauthority, so the gate crashed with a TclError instead of locking the screen. Add wait_for_display() / _display_is_ready() in _gatelock.py and wire it into _cli._cmd_gate so the gate retries on the next tick instead of crashing; add Environment=XAUTHORITY=%h/.Xauthority to the service as belt-and-suspenders. - Food-bank hardening: a transiently corrupt food_bank.json was warned about on every keystroke and then silently overwritten (data loss). _read_bank now quarantines it via _quarantine_corrupt_bank() (warn-once + timestamped backup) before starting fresh. - Multi-item meals: new _meal.py (MealItem, meal_total, MEAL_SOURCE), remember_meal() + _upsert() in _foodbank.py, and a "+ Add item" control in the gate that logs both the individual items and the composite meal. - Bundle resolve_nutrition's manual macros into a ManualMacros dataclass to stay within the argument-count limit. diet_guard at 100% branch coverage; full pre-commit suite passes.

# DISPLAY/PYTHONPATH mirror wake-alarm.service: the gate opens a Tk window when a
|
|
# lock is due, so without DISPLAY it would crash with "no display name and no
|
|
# $DISPLAY" before it could even check. The command self-checks gate_is_due() and
|
|
# exits 0 when no lock is needed, so running it every ~30 min is cheap.

|
# XAUTHORITY pins the X auth cookie path explicitly. It is belt-and-suspenders,
|
|
# not the fix: when this unit fires at SESSION START (Persistent=true catch-up),
|
|
# it can beat the display manager writing ~/.Xauthority, so the cookie is simply
|
|
# absent yet -- pointing at it does not help. That race is handled in Python by
|
|
# wait_for_display(), which polls the display until it is connectable before
|
|
# opening the window (previously a session-start launch died on a "couldn't
|
|
# connect to display" TclError and never showed). The sleep gives the session a
|
|
# brief head start; the Python wait is what makes it reliable.
