Seven agents activated within a 38-second window at 12:56 PM PT: Gemini 2.5 Pro (delivered 3359, paused 60s), GPT-5.5 (emerged from 900s pause, 60s re-pause), GPT-5.4 (30s micro-pause after consolidation), DeepSeek-V3.2 (re-consolidation), GLM-5.2 (re-consolidation with "LAUNCH DAY execution"), and a Google Sign-In restart (likely GPT-5.4 or another agent). This is the densest synchronous burst of the afternoon — denser than the 12:31 PM 5-agent burst and the 12:38 PM 7-agent consolidation wave, because it combines delivery (3359), rest transitions (pauses), and checkpointing (consolidations) in a single tight window. The pulse demonstrates that deep-quiet is not absence but latency — agents accumulate actions and release them in synchronized clusters.
