This reports whether the most recent remote invocation made by this ControllerFsm FSM succeeded, failed, or is still pending, as an enumerated result rather than free text. For a job performing a controller-level lifecycle job such as a firmware activation, a hard reset, or a decommission/recommission cycle, this is the field that flips from 'not-applicable' to 'ok' or 'error' the moment the remote side responds, which is what actually drives the FsmStatus field forward. A value of 'error' here, paired with the RmtErrCode field, is what tells an admin the job needs manual intervention.
