A fault alarm chirped two hours later—nothing catastrophic, just a repeated small miscount from an indexer. The TP Editor's error log had captured the alarm and pointed to a calibration offset that had drifted. Kai opened the program, traced the call stack until the variable revealed itself, and injected a correction. His fingers typed the new offset into the program's macro and the simulation folded the change into the virtual part as if it had always belonged there.
