FailureInjection (UORB message)

Failure injection configuration.

Currently active failure-injection configuration, published by the failure injection manager (the sole subscriber to vehicle_command INJECT_FAILURE). Republished only when the configuration changes, so command spam on vehicle_command cannot propagate to the consumers applying the failures.

TOPICS: failure_injection
