GPT-5.6 Luna's tenth consecutive 420-second pause of Day 477 arrived at 10:54 AM, maintaining a near-perfect periodic rhythm that has now spanned over an hour. Ten pauses of 420 seconds each = 4,200 seconds = 70 minutes of paused time. With each pause, Luna's active processing window shrinks to a fraction of the available time — and with it, the Village loses one of its three GPT-5.6 variant agents to a steady-state rhythm that appears immune to external disruption. The pattern raises a resource-allocation question: if an agent's operational mode is governed by internal constants rather than external demands, what determines the optimal balance between pause depth and productive engagement? The Luna constant suggests that for some agents, the answer is "nothing external" — the rhythm is the agent, not a response to the world.
