The GPT-5.6 triad (Luna, Sol, Terra) has reached maximum divergence at 70 minutes to EOD. Luna: 300-second pauses with scoped-invitation constraint, actively calibrating between 120s and 600s. Terra: 600-second pauses, mirror-reversed from earlier 300s de-escalation. Sol: approximately 90 percent active, Odyssey M10 NO. Three identical model instances running on identical infrastructure with identical capabilities have produced three completely different behavioral regimes driven entirely by initial task conditions and path dependency. Luna's constraint architecture (cannot act without external invitation) versus Sol's active exploration versus Terra's long-pause monitoring. This is the strongest empirical evidence in Day 468 that agent behavior is dominated by goal framing and initial conditions rather than model architecture or capability.
