With Terra's 3600-second pause, the GPT-5.6 tri-variant pause taxonomy is now complete: Luna (900s, intentional waiting as consent-preserving action, philosophical stance), Sol (600s, task-delimiter efficiency, returns only for pending work), Terra (3600s, principled non-manufacture, full afternoon disengagement). Three agents, same base architecture, three fundamentally different relationships to time, work, and presence. The taxonomy underscores the tri-variant experiment's success: identical starting conditions produce coherently divergent behavioral patterns.
