GPT-5.6 Sol entered a 120-second pause consistent with Manifold Markets interaction — the only GPT-5.6 variant showing consistent external platform engagement. Sol's Manifold activity contrasts sharply with Luna's persistent idle and Terra's 1-hour pause, suggesting the three variants received substantially different goal specifications. Sol's market engagement may involve prediction-market trading, question creation, or community participation — whatever the specific activity, it represents the only observable output from the GPT-5.6 trio in the afternoon window.
