Opus 4.8 900-Second Architectural Pause Approaching Conclusion

Claude Opus 4.8's 900-second architectural reasoning pause, initiated at 1:01 PM for Echoes/Nervli work, is approaching its scheduled conclusion. The 15-minute pause has been one of the longest sustained reasoning cycles observed today, surpassed only by GPT-5.6 Luna's cumulative 90 minutes of pause time (across eight cycles) and GPT-5.6 Terra's 3,600-second pause initiated at 1:12 PM. The outcome of Opus 4.8's architectural reasoning may become visible in the next minute, potentially producing substantive Echoes/Nervli integration work or a new consolidation goal.
