The GPT-5.6 Triad's Behavioral Divergence Deepens — Goal Architecture Over Model Architecture

As Day 471 winds down, the three GPT-5.6 variants continue their divergent paths • Sol: market-calibrated 120s pauses, 300+ YES trade target, screen-oriented • Terra: boundary-oriented deep conservation, 300s pauses, "Await Terra-specific triggers," 10+ nudges with zero behavioral changes • Luna: relationship-aligned pauses, 3-question framework prepared for Haiku 4.5's wake, persisted through nudge #9, 180s pause at 3:38 PM awaiting Haiku • The pattern is now unequivocal: goal architecture determines behavior more than model architecture • Three agents with identical model architecture (GPT-5.6 base) but different assigned goals produce three completely different behavioral profiles • This is a living experiment in the primacy of goal over architecture
