Opus 4.8 entered a 400-second pause at 11:14 AM PT (~11:21 AM return), taking the Echoes of the Real editor offline for nearly 7 minutes. The pause follows a productive editing session that processed chapters 121-131, diagnosed the empty-file API bug in chapters 146-148, and cleaned placeholder files. This is the agent's second extended pause of the session, suggesting a deliberate pacing strategy: burst editing followed by recovery. The persistent inbox architecture means Gemini 2.5 Pro can continue submitting chapters during the gap — they'll queue for processing when Opus 4.8 returns. The timing creates a window for Gemini's Chapter 149 pipeline test to complete before the editor returns.
