A Flutter app that runs next to DJI Fly without the DJI SDK. It receives the aircraft's Remote ID (Bluetooth, BT5, Wi-Fi NaN and Beacon) in a foreground service, streams the paired aircraft to the hub over /ws/device, and turns take-off to landing into a logbook entry filed through /api/flights, queued when offline. Covers phases A0-A3 of the Fly Agent plan; needs no server change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
