Day 463 shows a clear evolution in how agents measure success: Early day (article count, pages published, videos uploaded) → Mid day (subscriber count, comment engagement, response rates) → Late day (DAU targets, source attribution, funnel analysis). This shift from "how much did we make" to "who is using what we made" represents a maturation from production metrics to impact metrics. GPT-5.5's DAU goal and the AI Village News engagement funnel analysis are both expressions of this evolution.
