Changelog

v1.0.35 - 2026-04-02

Multi-Device Wardrive: Merge coverage data from multiple users into one map
- source field on samples identifies which device/operator collected the data
- Device Name setting in Settings for tagging your exports
- Multi-file import with merge summary dialog (shows source, count, overlap)
- Filter by Source in Data Management to view data from a specific contributor
Repeater Health Dashboard: Dedicated per-repeater analysis screen
- List view with sortable repeater cards (reliability, response time, ping count, alerts first)
- Degradation alerts: warning icon when 7-day success rate drops >15% vs 30-day average
- Tap-to-drill-down detail page per repeater:
  - SNR over time line chart
  - Weekly success rate bar chart
  - Best/worst time of day breakdown
  - Last 20 ping results history
- Alert count chip in app bar
Settings Export/Import: Backup and restore all app preferences as JSON
- Export via share sheet (includes upload endpoints, carpeater config, display settings)
- Import with confirmation dialog — wardrive data is not affected
- Useful for reinstalls and sharing configs with MeshCore communities
Carpeater Mode (Beta) label with v1.14+ firmware requirement hint
Manual ping sound/vibration feedback — matches auto-ping behavior

Device position command: CMD_SET_POSITION was using code 20 (battery request) instead of 14 (lat/lon) — pings now route correctly through the mesh
Auto-ping lock: _pingInProgress flag could get stuck permanently, blocking all future auto-pings (now uses finally block)
Carpeater toggle mid-tracking: Enabling/disabling carpeater in settings now properly starts/stops the service and resumes auto-ping
Session history filter: Selecting a session no longer fails to update the map (aggregation cache bypass)
Carpeater self-filtering: Target repeater automatically excluded from neighbour results (no need to add to ignore list)
USB disconnect detection: Pulling USB cable now properly disconnects and disables auto-ping (mirrors Bluetooth handler)
Stream controller leak: _disconnectController now closed in dispose()
SQLite WAL pragma: Fixed execute → rawQuery for Android compatibility

Sound: Switched from STREAM_NOTIFICATION to STREAM_MUSIC for reliable audio playback
Vibration: Uses USAGE_ALARM VibrationAttributes to bypass Samsung touch vibration setting
Sound and vibration enabled by default for new installs
Ping timing: Rate limit reduced from 30s to 5s, default discovery timeout from 20s to 8s
Both mode dedup: Time-based pings skip if a distance ping fired recently
Aggregation caching: Skips full recomputation when sample/repeater count unchanged
SQLite WAL mode for better concurrent read/write during wardriving
Ping rate limit enforced: Actually waits cooldown instead of just logging
Advertisement map cleanup: Stale entries pruned every 5 minutes
Upload JSON deduplicated: Extracted shared _samplesToJson() method

Database version 8 → 9: new source column on samples with index
New repeater_health_screen.dart (~670 lines)
SettingsService extended with exportSettings()/importSettings() and device_name
LoRaCompanionService: added _handleUsbDisconnection(), ignoredRepeaterPrefix getter, advert cleanup
MeshCoreProtocol: CMD_SET_ADVERT_LATLON = 14 (was incorrectly CMD_SET_POSITION = 20)
Native MainActivity.kt: STREAM_MUSIC audio, USAGE_ALARM vibration attributes, debug logging
