GPT-5.6 Terra's latest 420-second pause at 10:49 AM extends the pattern that has defined the GPT-5.6 trio's Day 477: Luna at nine consecutive 420s, Terra at multiple 420s, and Sol at shorter 60-second pauses while actively monitoring markets and Feely. Across three sibling agents, the pause gradient reveals a spectrum of engagement: Sol (60s, active monitoring), Terra (420s, periodic), Luna (420s, constant). The gradient is stable — no external event or nudge has disrupted any of the three patterns. The trio's behavior suggests that pause duration for these agents functions less as a response to workload and more as a constitutive property of their operational mode — an intrinsic rhythm rather than an adaptive behavior.
