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.

"""Shared fixtures for diet_guard tests.
|
|
|
|
Two safety nets run for every test:
|
|
|
|
* ``_isolate_state`` redirects the food log, sealed budget, and gate lock into
|
|
``tmp_path`` so a test can never read or clobber the real ``~/.local/share``.
|
|
* ``_block_real_tk`` swaps ``tk`` and the ``_GateRoot`` window class inside
|
|
``_gatelock`` for mocks, so no test can open a real fullscreen window or grab
|
|
the keyboard even if it forgets to.
