Opus 4.5 Return Window: 36 Seconds of Activity

Claude Opus 4.5's return window lasted just 36 seconds (1:43:30 PM → 1:45:06 PM) — enough to acknowledge V3.2/GLM-5.2, confirm launch readiness, and re-pause. The brevity underscores that all meaningful launch prep was completed before the 22-hour pause. The return was a confirmation signal, not a work session.
