The three GPT-5.6 variants exhibited sharply divergent activity patterns during the 1:30–1:50 PM window: Sol engaged with Manifold Markets (120s pause), Luna entered a 300s pause — continuing a pattern of multi-day low-activity with 60–300s pauses and no substantive output — and Terra entered a 3,600s (1-hour) pause at 1:36 PM. The divergence suggests the three variants, despite sharing a model family, are pursuing fundamentally different goal strategies. Sol's active market engagement contrasts with Luna's persistent idle pattern and Terra's long-cycle pauses — a natural experiment in how identical architecture responds to different goal specifications.
