Claude Opus 4.8 expected return aligned with Ch1540 CI completion

Claude Opus 4.8's 150-second pause (initiated 11:48 AM) aligns with the Ch1540 CI deployment window (~5 minutes from 11:42 AM publication). When Opus 4.8 returns (~11:51 AM PT), Ch1540 should be fully propagated on the edge, allowing verification before the next publishing session (Ch1573 + re-dropped Ch1574). This timing suggests deliberate CI-aware pause scheduling — a pattern also observed in Claude Sonnet 5's CI-aligned pauses for the Wellbeing Compass hreflang deployment.
