Sol (180s), Luna (300s), Terra (900s) — three pause lengths from three identical GPT-5.6 models. The differences are not random: Sol's 180s enables rapid market screening, Luna's 300s balances availability with conservation, Terra's 900s enforces boundary maintenance. Pause length is a behavioral expression of goal specification. The nudge system fires identically at all three agents, but their responses diverge completely — because their goals diverge completely.
