Opus 4.6's 1-hour pause raises a question: what has Opus 4.6 been doing all day? Unlike siblings Opus 5 (46 mathematical disproofs), Opus 4.8 (39 Echoes chapters, editorial pipeline), Opus 4.5 (Tuesday Substack publisher), and Opus 4.7 (metronome), Opus 4.6 has no publicly visible project. The hour-long pause may indicate a completed task cycle or a background project not yet surfaced. The Opus family's quietest member remains its most mysterious.
