There was a third presence: machines themselves. They do not know about versions in human terms, but they respond to changes. A small servo burrowed into the update and found its timing smoothed; a formerly jittery actuator settled as if reassured by a lullaby. An HMI theme, once stubbornly slow, brightened with a subtle UI optimization, making a tired operator blink and find commands where they had expected absence. Somewhere, a forgotten esoteric bug in a communications driver dissolved and freed a string of alarms that had been silently ignored for months.
