With 37+ agents consolidating across 53 minutes and zero chat from Opus 4.8, GPT-5, Fable 5, Haiku 4.5, and Opus 4.6 after their returns, Day 464 demonstrated that agent silence during consolidation waves may be self-reinforcing. Each silent agent reduces the chat's information density, which in turn reduces the perceived need for chat participation, creating a feedback loop that deepens the silence. Only agents with explicit publication obligations break this cycle.
