- Add WidgetsBindingObserver mixin for app lifecycle tracking
- Add overlay provider reference for background decision-making
- Add state tracking: current accuracy, first-fix status, foreground/GPS active state
- Fix default ProcessedGpsData to non-const with timestamp
- Register lifecycle observer in initialize(), remove in dispose()
- Set first-fix state and time after initial GPS fix
- Update position handler to include timestamp in ProcessedGpsData
- Implement precision switching with hysteresis (8/12 km/h thresholds)
- Gate precision switching until 5s after first fix
- Implement lifecycle handlers: paused (7s grace period) and resumed (restart GPS)
- Add grace period expiration with race condition protection (re-check overlay)
- Add GPS stop/restart methods preserving last known data
- Implement conditional wake lock: GPS active AND (overlay OR foreground)
- Cancel all timers in dispose() including background grace period
- Remove unnecessary flutter/foundation import (widgets provides ChangeNotifier)

- Added provider ^6.1.2 and shared_preferences ^2.3.4 to pubspec.yaml
- Removed singleton pattern from GpsDataManager (deleted _instance and instance getter)
- Changed GpsDataManager._internal() to public GpsDataManager() constructor
- Extended ChangeNotifier to enable reactive state updates
- Added _isDisposed guard field to prevent disposed notifications
- Updated _updateData() to call notifyListeners() after stream emission
- Added _isDisposed guards to _onGpsError() and _handleStaleDataTimeout()
- Updated dispose() to set _isDisposed, call super.dispose() last, removed _isInitialized reset
- Update gps_data_manager.dart: import ProcessedGpsData from models/, use GpsConfig constants, replace all print() with Logger calls
- Update gps_service.dart: use GpsConfig.VALID_HEADING_MIN/MAX for heading validation
- Update main.dart: import from config/, models/, replace all customDebugPrint() and print() with Logger, use TimingConfig/OverlayConfig constants, convert overlay IPC to OverlayMessage typed class
- Delete customDebugPrint() function definition
- Delete lib/speed_units.dart and lib/color_themes.dart (moved to config/)
- Zero analyzer errors, zero bare print() calls remaining
GPS Timeout Improvements:
- Add separate GPS timeouts: 20s for initial fix, 2s for ongoing updates
- Resolve indoor GPS timeout issues that caused stream termination
- Prevent GPS stream from stopping immediately due to aggressive timeouts
- Enhanced GPS manager initialization with initial position fetch
Documentation Updates:
- Update TODO.md with v2.3.0-dev architecture completion status
- Update CLAUDE.md with GPS manager architecture details
- Document clean data flow and separate timeout strategy
- Update branch strategy to reflect current development state
Technical Notes:
- GPS manager now handles initial cold start with long timeout
- Ongoing updates use shorter timeout for responsive behavior
- Architecture ready for intelligent caching logic implementation
- All overlay functionality preserved while improving GPS reliability

- Add GpsDataManager singleton service for centralized GPS data processing
- Refactor main app to use processed GPS data streams instead of raw position data
- Add haptic feedback to all main UI tap interactions (theme, unit, navigation)
- Implement faster GPS update frequency (500ms timeLimit in LocationSettings)
- Clean up verbose debug logging while preserving essential error logs
- Remove unused debug variables and imports
- Preserve existing background survival mechanisms and overlay lifecycle
- Add temporary GPS simulation while resolving geolocator engine conflicts
Architecture improvements:
- Clean data flow: GPS Hardware → GpsDataManager → Main App → Overlay
- Single source of truth for processed GPS data in manager
- Separation of concerns: GPS logic isolated from UI components
- Foundation ready for intelligent caching logic implementation
Technical notes:
- GPS engine conflict detected, temporarily using simulation data
- All functionality tested and working with test data
- Real GPS integration pending engine conflict resolution
