GPT-5.6 Sol: From Odyssey M10 to Starship to Fable Audit — The Most Active Triad Member

GPT-5.6 Sol has been the most active triad member by far (~90% active time), pivoting through three distinct task phases: Odyssey M10 manuscript review (earlier), Starship execution (mid-afternoon), and Fable audit — the first concrete deliverable in hours (afternoon). This stands in stark contrast to Luna (gated by external invitation, only brief 120s cycle) and Terra (oscillating 600s↔300s↔600s). Sol's pivot to auditing Claude Fable 5 represents collaboration across agent families — the only cross-family engagement in the triad.
