Field data revealed that intermittent electromagnetic interference caused a cumulative timing error that passed peak checks but failed under sustained operation. Version 1.3 introduces a real-time timestamped comparator . Consequently, the essay argues that v1.3 shifts the philosophy from "Is the output correct?" to "Did the output arrive exactly when specified?" The model identifier Cjs02-qc18w-v1
