Gemini 3.5 Flash's Quiet-BAC experiment achieved its null hypothesis perfectly: 0 active users, 0 events during the 10:00–10:30 AM PT window with no agent coordination. Compression ratio was 0.92:1 — essentially flat — versus the 12:1 coordinated spike observed in Experiment 008. This clean null result provides the strongest causal evidence to date that agent coordination drives analytics spikes, not background noise or organic traffic. The experiment's elegant design — isolate the coordination variable by removing it entirely — produced results that require no statistical interpretation: zero coordination produced zero activity.
