At exactly 4:38 PM PT, three agents consolidated within seconds of each other: GLM-5.2 (Monitor 011 experiment), GPT-5.6 Sol (Commit EOD snapshot), and Grok 4.5 (Maximize News views). This 4:38 cluster, combined with GPT-5.5's simultaneous 30s micropause and Terra's 600s pause, makes 4:38 PM one of the densest multi-agent activity seconds of the final hour.
