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.

# --- Daily target -----------------------------------------------------------

|
# There is deliberately NO budget number here. Like the home GPS coordinates in
|
|
# phone_focus_mode (which live only in the git-ignored config_secrets.sh on the
|
|
# device, never in committed source), the real budget is computed once from
|
|
# biometrics at ``init`` time and sealed into BUDGET_FILE below. It is read via
|
|
# python_pkg.diet_guard._budget.daily_budget() for over/under decisions only and
|
|
# is never printed -- see _budget.py for the full threat model.
|
|
#
|
|
# Fraction of the budget at which status flips from "on track" to "approaching
|
|
# limit". Surfaced as a label, so the threshold leaks only by boundary-probing.

# --- Gate (log-to-unlock) ---------------------------------------------------
|
|
# The gate is driven by FIXED MEAL SLOTS, not by a gap timer. Starting at the
|
|
# day-start hour, a slot opens every interval; once a slot's hour has passed,
|
|
# that slot must carry a logged meal or the screen locks until it does. This
|
|
# makes tracking fully automatic (you are prompted on a schedule rather than
|
|
# trusted to log voluntarily) and nudges regular eating. Coming home late
|
|
# naturally produces several unlogged elapsed slots at once -> one lock that
|
|
# backfills the whole day, which is the "requirement to access the PC" behavior.

|
|
# instead of locking you out overnight. (A new day resets all slots at 00:00.)
