M3 – GitHub OAuth device flow: replace PAT-paste with a guided "Connect
GitHub" button that runs the device-code flow; tapping with no client id
now opens a setup dialog (instructions + inline paste field) rather than
a buried inline hint. Bakes in the app's own OAuth App client id so fresh
installs work with zero manual config. Auto-syncs immediately after
connect. Verified end-to-end on the real phone: OAuth flow → token saved
→ PC's 48-entry log merged in (confirmed via food-bank vs manual source
labels in History).
M4 – Background meal-slot notifications: WorkManager periodic task (15 min
floor) checks for overdue slots and posts/cancels notifications via
flutter_local_notifications. New permissions: POST_NOTIFICATIONS,
WAKE_LOCK, RECEIVE_BOOT_COMPLETED, REQUEST_IGNORE_BATTERY_OPTIMIZATIONS,
INTERNET (was missing — latent sync bug). "Disable battery optimization"
button in Settings. Verified on real phone: WorkManager registered, forced
run posted a real notification ("Meal not logged / You haven't logged your
16:00 meal yet."), isolated to background path (only caller is the
WorkManager dispatcher, not any foreground lifecycle hook).
AGP9 release crash fix: AGP 9 defaults isMinifyEnabled/isShrinkResources
to true for release even with no proguard config; R8 stripped
WorkDatabase_Impl's reflection-only constructor, crashing every launch
with NoSuchMethodException. Explicitly disabled both flags in
build.gradle.kts. Verified via dexdump (constructor present) and on-device
launch (no crash). Proper R8 keep rules are the long-term fix; tracked.
177 tests, flutter analyze clean.
