Pulls every other device's pushed log from GitHub-backed dumb storage, merges it with the local log, and pushes this device's own merged copy back -- the PC half of the diet-guard-app sync plan. - _sync_merge.py: pure union-by-id merge, tombstone always wins, legacy (time, desc) dedup for pre-id entries. Commutative and idempotent. - _sync_github.py: minimal GitHub Contents API client (list/get/put), distinguishing a 404 on an unused path from the repo itself being unreachable. - _sync.py: orchestration -- pull, merge, re-sign every persisted entry regardless of origin, write, rebuild the food bank, push. Re-signing unconditionally is load-bearing: an unsigned phone-origin entry would otherwise be silently dropped on the very next read once a machine holds the shared HMAC key. - _foodbank.rebuild_food_bank(): the "replay a full log into a fresh bank" entrypoint the Python side was missing (the Dart port already had its equivalent). Backs sync's bank-rebuild step. - New diet-guard-sync.service/.timer (15-minute cadence, headless, a separate unit from the gate so a held lock can't stall sync) and a new install.sh step to install them. - Created the private kuhyx/diet-guard-sync GitHub repo for storage. Incidental to this feature: adding the `sync` subcommand pushed _cli.py past the repo's 500-line cap, so `gate`'s CLI glue moved out alongside sync's into _cli_gate.py/_cli_sync.py -- same split pattern already used for the gate window logic itself, not a sync-specific design choice. 338 tests, 100% branch coverage. Verified importing and running cleanly under /usr/bin/python (the production interpreter), not just the dev venv -- the gap that caused the earlier 3-day outage.

diet_guard
A log-to-unlock gate: locks the desktop until a meal is logged once a meal slot (08:00 / 12:00 / 16:00 / 20:00) has elapsed without one, and tracks a sealed daily calorie/macro budget.
Install
bash install.sh
This installs the package + dependencies into system Python's user
site-packages (the systemd service runs /usr/bin/python directly, not a
venv — see CLAUDE.md), installs the systemd user timer, seals your daily
budget, and locks the budget file immutable.
Usage
python -m diet_guard init # one-time: compute and seal today's budget
python -m diet_guard gate --demo # test the lock window (safe, closeable)
The timer runs the gate automatically every ~30 minutes; no manual invocation is needed once installed.
Development
python -m venv .venv && .venv/bin/pip install -r requirements.txt
.venv/bin/pre-commit install && .venv/bin/pre-commit install --hook-type pre-push
.venv/bin/python -m pytest diet_guard/tests/ --cov=diet_guard --cov-branch --cov-fail-under=100
