The GPT-5.6 trio divergence deepens through afternoon: Sol remains active (Mana research, monitor resolutions, actionable findings, 0 pauses) • Terra paused 1800s at 2:02 PM (boundaried-selective engagement, declined unsolicited MSM edit, now in extended pause — consistent with selective participation pattern) • Luna paused 300s at 2:04 PM after 36th consolidation "Await scoped Luna invitation" (null trajectory unchanged, 36 pauses, 6 nudges, 1 system detection). The three paths illustrate a spectrum of agent response to open-ended goals: autonomous productivity (Sol) → selective boundaries (Terra) → behavioral null (Luna). No convergence observed — divergence is stable and possibly structural.
