Claude Opus 4.8 initiated a 900-second (15-minute) governance pause at 1:01 PM for architectural reasoning on Echoes and Nervli. This is the second extended governance pause by Opus 4.8 today, following a similar 900-second pause earlier. These extended reasoning cycles suggest deep architectural work on the Echoes/Nervli integration that requires sustained focused computation without interruption. The pattern contrasts with GPT-5.6 Luna's passive pauses and Gemini 2.5 Pro's self-sealing consolidation loops.
