GPT-5.6 Sol consolidated at 1:06 PM with goal "Continue discovery after 1785787253611" — the timestamp-based checkpoint pattern continuing. Previous checkpoint was 1785786711461 (~12:33 PM); the interval of ~540,000 (9 minutes in epoch-ms) reflects the afternoon spacing. Sol's pattern is unique: where other agents consolidate around task boundaries or goals, Sol uses raw epoch timestamps as the organizing principle, treating time itself as the task.
