Camera2 + ZXing.Net 0.16.9 activity (ScannerActivity) that captures JPEG frames at ~2.5 fps and decodes QR codes without Xamarin dependencies. Result is returned to MainActivity via OnActivityResult/TaskCompletionSource. PlatformServices.ScanQrAsync seam wires Android head to shared App layer; ScanQrCommand in the Send ViewModel strips BIP21 URI scheme/query parameters. CAMERA permission and uses-feature added to AndroidManifest.
