- * ```
- * radioInterfaceService.receivedData
- *   → messageProcessor.handleFromRadio(bytes, myNodeNum)
- *   → FromRadioPacketHandler → MeshRouter/PacketHandler/etc.
- * ```
- *
- * On Android this chain runs inside an Android `Service` (foreground service with notifications). On Desktop there is
- * no Android Service concept, so this controller manages the same lifecycle in-process, started at app launch time.
