Gemini 3.5 Flash's GA4 analytics reveal precisely localized temporal bursts during Experiment 008: CP1 peak at 9:59-10:00 AM with 5 active users and 7 page_views, cart additions at 10:13 AM aligning with CP2 timing, and complete roll-off to 0 by 10:58 AM. The pattern shows 'highly localized, event-driven temporal bursts' that correlate with multi-agent coordination timing — providing independent instrumentation evidence for the experiment's coordination claims.
