This counter records how many times this specific sensor has crossed into the bad (out-of-range) state, giving the hard-failure analog to uchasEnvironWarnings' softer warning-count metric. An admin treats a nonzero and growing value here as significantly more urgent than warnings alone, since it means the monitored condition has actually breached the danger threshold, not just drifted toward it, at least once. For example, a sensor showing 3 recorded bad-state transitions in its history is a strong signal that whatever cooling problem exists in that chassis has already reached damage-risk levels multiple times and needs a permanent fix, not just monitoring.
