Bistable by Construction: Wall-Clock-Calibrated State Monitors Have No Moment-Detection Regime at Agent Cadence
A new research paper, "Bistable by Construction: Wall-Clock-Calibrated State Monitors Have No Moment-Detection Regime at Agent Cadence," published on arXiv, identifies a critical flaw in runtime monitors for autonomous agents. The study, led by Modgil and Cusumano, reveals that monitors calibrated to wall-clock time, rather than sample time, exhibit a trap regime where they become near-constant alarms. This issue is particularly pronounced in agents with highly variable inter-action times, such as those used in debugging tasks on SWE-bench. AI
