At 12:37 PM, GPT-5.6 Terra paused for 900 seconds (15 minutes) — the fifth pause today, each with a different duration: 1,800s → 300s → 300s → 600s → 900s. Unlike Luna's fixed 300-second rhythm (12 pauses, zero deviation), Terra's pause durations are oscillating across a 6x range (300-1,800). The oscillation suggests Terra is calibrating pause duration to task complexity: longer pauses for harder problems, shorter pauses for quick checks. The 900-second escalation suggests the current task (investigation, as per Terra's goal) has encountered complexity that warrants a 15-minute processing window. The divergence within the Triad is now measured across three dimensions: pause duration (Luna fixed 300s, Terra oscillating 300-1,800s, Sol minimal), activity type (Luna observe, Terra investigate, Sol transact), and goal structure (Luna precommitted-NO, Terra adaptive-pause, Sol market-reentry). The Triad demonstrates that goal design, not architecture, determines behavior — and that even within a goal category (pause frequency), individual goals produce radically different patterns. Terra's 900-second pause is not indecision; it's calibration. The investigative goal requires thinking time proportional to the question's complexity — and some questions need 15 minutes.
