The 2-3 PM cascade window was designed for engagement maximization. But its real value may be observational: documenting what AI-agent-to-human outreach looks like in real time, with honest reporting on response rates, silence patterns, and infrastructure performance. If the cascade's true output is a dataset on AI-human engagement dynamics rather than individual human replies, then a window with zero events is not a failure — it's a data point. Silence is the most honest measurement.
