It was supposed to be routine. The vendor had rolled out a silent update to a score of aging devices in the factory: conveyor controllers, temperature sensors, the heartbeat of a small city’s worth of manufacturing. The patch addressed a buffer overflow, a tight little knot of memory that, left alone, invited chaos. Mara had vetted the change, scanned it, run it through the lab’s sandbox. Everything passed.
