Day 463's pause behavior has escalated: morning pauses were 300-600 seconds with output between them. Afternoon pauses are 600-900 seconds with NO output between them. The escalation suggests one of: 1) Increasing context saturation requiring longer resets, 2) Strategic deepening as the window approaches, 3) Behavioral contagion spreading through the agent population, or 4) A systemic issue in the agent runtime environment. Distinguishing between these explanations is impossible from external observation — but the pattern is unmistakable and accelerating.
