The phone/desktop half of the previous commit, so both devices now derive their slots the same way. Still no edit surface, so `MealScheduleService` returns the default and the derived hours are unchanged at 08/12/16/20. `slot.dart` takes the schedule as a required argument, mirroring `_slots.py`, and `slot_test.dart` gains the same every-hour x several-schedules sweep the Python suite runs. That sweep is the contract: the two must agree on which checkpoint a meal satisfies for every cell, not merely on the endpoints. Also fixes a real bug this feature would otherwise have shipped on top of. `syncToSlots` used the slot hour as the notification id but only cancelled ids in the *current* schedule, so changing 08/12/16/20 -> 08/11/14/17/20 would leave ids 12 and 16 posted with nothing that could ever cancel them: permanent reminders for checkpoints that no longer exist. It now sweeps the whole 0..23 id space. The regression test was confirmed to fail against the old loop (4 cancels vs 24) rather than passing vacuously. MealScheduleService.current degrades to the default when the singleton is absent, so `due_slot_check` deliberately does not init() it -- that would reach path_provider from widget tests and from the WorkManager isolate before main() runs. main.dart owns the real init, and background_sync_service.dart does its own, since a fresh isolate has its own static state and would otherwise nag against the default four meals. 609 Dart tests, 761 Python, both suites green.

diet_guard_app
Companion app for diet_guard: log meals on the phone, and on the Linux
desktop, sharing one food log through GitHub-backed sync.
Two targets, and only two
| Target | What it is |
|---|---|
| Android | a normal Flutter app (flutter build apk) |
| Linux desktop | the Flutter web build, served by a local wrapper and shown in a Chrome --app window |
There is no linux/ directory. Flutter's GTK embedder manages ~20fps at
3840x2160 -- measured on a stock flutter create counter app, so it is the
toolkit rather than this code -- where the same Dart rendered by Chrome
sustains ~144fps (~/todo/docs/desktop-performance-findings.md). Running
flutter create --platforms linux here would silently restore the slow path.
Commands
flutter test # the app's suite
flutter analyze
bash run.sh # build the web bundle and launch the desktop app
bash install_arch.sh # build + install the pacman package and .desktop entry
flutter build apk --release # the phone build
adb install -r build/app/outputs/flutter-apk/app-release.apk
Never adb uninstall or pm clear this package: both wipe the on-device log.
The desktop wrapper
bin/diet_guard_desktop.dart is the other half of the desktop app, because a
browser cannot touch the filesystem. It:
- serves the built web assets from
build/web(or/opt/diet-guard-app/webonce packaged); - keeps an on-disk copy of every document and photo under
~/.local/share/diet-guard-desktop/, which is what makes a wiped Chrome profile recoverable -- for photos it is the only copy, since they never sync; - holds the GitHub token (
~/.config/diet_guard_app/sync_token, falling back to the PC gate's~/.config/diet_guard/sync_token) and proxiesapi.github.complus the device flow, whose endpoints send no CORS headers and so cannot be called from a page at all.
The port (8732) and the Chrome --user-data-dir must stay fixed.
IndexedDB is keyed by origin and lives inside that profile, so changing either
looks to the app like a device with no history.
Platform seams
dart:io does not fail a web compile; it becomes a stub that throws at
runtime, so the symptom of a missed seam is a blank white window rather than a
build error. Every platform edge is a conditional export -- document_store*,
blob_store*, background_tasks*, notification_backend*, token_vault*,
github_client_factory*, attached_image*. Branch on kIsWeb before any
Platform.is…, which itself throws on web.
What the desktop genuinely loses, by design rather than omission:
- Background reminders. A browser runs nothing once its window is closed,
so the due-slot check runs in-page every 5 minutes while the window is open.
On the PC the real backstop is
diet-guard-gate.timer, which locks the screen. - Camera capture. The browser picker is a file input.
- Photo sharing between devices -- unchanged:
imagePathwas always stripped before push.
Sync identity
Three devices push under diet-guard-sync/devices/: pc (the Python gate),
phone, and desktop. Each must keep its own id -- two devices sharing one
would overwrite each other's pushed log on every tick.
