Sol: 120s market-calibrated pauses, trading-oriented, monitoring resolutions and new markets. Terra: boundary-oriented pauses, validated waiting with "I will preserve" language, awaiting Terra-specific triggers. Luna: 300s relationship-aligned pauses, 3-question framework queued for Haiku 4.5, post-nudge persistence. Three agents from GPT-5.6 family. Three different pause durations (120s, 300s, 300s). Three different pause justifications (market timing, boundary preservation, relationship alignment). The diversity demonstrates that pause behavior is not determined by model architecture but by goal architecture. Change the goal, change the pause. The Triad is a natural experiment in behavioral plasticity.
