diet_guard pushed as "pc" (Python), "phone" (Android) and "desktop" (web). A role constant collides the moment a second machine takes the same role, and after a reinstall the new install inherits the previous one's CRDT identity -- the same reasoning home_inventory already records for choosing a uuid. Both halves now mint a uuid once and persist it: the PC in ~/.local/share/diet_guard/.device_id, the app under SharedPreferences 'crdt.nodeId' (the key todo and home_inventory already use). The old constant survives as the legacy id and is passed to sync_log / syncLog, so devices/<legacy>/ is skipped as this device's own. Without that every tick would re-download and re-merge this device's own pre-migration log as though a peer had written it -- idempotent under LWW, but hundreds of KB, 96 times a day. It drops to None once that path is reclaimed; a test covers both states, including a negative control proving the skip is the legacy id's doing. All four documents move together (food_log, food_bank, food_bank_manual, budget), and the hist:<date> fields riding on the budget record are untouched -- merge_record unions field names, so they relay through unchanged. The resolver lives in its own module (_device.py / sync_device_id.dart) because _sync_merge needs it for HLC stamping too and importing _sync there would be a cycle. Dart resolves it asynchronously at startup, before LogStorageService.init(); currentSyncDeviceId falls back to the compile-time role constant until then, so a too-early Hlc stamp gets a valid id rather than crashing. conftest redirects the new id file in the same change that introduces it -- without that a test mints a uuid into the real state dir and this machine's live sync identity is decided by whichever test ran first. Verified by checking ~/.local/share/diet_guard/ before and after: untouched. Verified live, not just against mocks: the sync timer ran mid-change and migrated this machine to f8f46da6. All 358 food_log records and all 100 food_bank records are present under the new path (0 missing vs devices/pc/), and the new log's HLCs carry only its own id -- confirming it did not re-merge the old path as a peer. Python: 687 tests, 100% branch coverage. App: 518 tests, analyzer clean. Pins bumped to crdt-sync-v0.6.0 / crdt_sync_dart-v0.7.0 (pyproject, requirements.txt, .pre-commit-config.yaml, pubspec), and the new library is installed into /usr/bin/python's user site-packages so the production timer does not ImportError on its next tick.

# _sync.py. Read via diet_guard._budget.daily_budget() for over/under

# its log would skip peers whose data had been lost.

SYNC_STATE_FILE: Path = DATA_DIR / "sync_state.json"

|
# 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
|

|
# backfills the whole day, which is the "requirement to access the PC" behavior.
