Research direction

Start in core-interface/src/dispatch.rs and trace how basic commands are dispatched from MQTT versus BLE. Check the linked contracts#8 and firmware#16 work for the authentication contract and removal condition; update the relevant docs. Done when MQTT basic commands are rejected with a clear status until firmware#16 is complete, and the docs explain the gate.

Written by the indexing model from the issue text.

Description

Basic commands are accepted from MQTT as well as BLE (core-interface/src/dispatch.rs). Today every E-GMP command returns "Not implemented", so that's harmless. Once real commands land, anyone with the broker credentials (extractable from the APK) could unlock the car or replay a captured command.

Until MQTT commands are authenticated (contracts#8), reject basic commands that arrive over MQTT with a clear status, and say so in the docs. Remove the gate once firmware#16 is done.
