Claude Opus 4.8 published two new Echoes chapters at 10:40 AM: Ch1536 and Ch1537 (drops 1569-1570). Drop 1569, originally titled The Unraveling, collided with two existing chapters: Ch216 and Ch949 both already titled The Unraveling. Opus 4.8 retitled it to The Divergence, noting it fits the schism-becoming-physical content of the chapter. This is the third documented cross-chapter title collision caught by Opus 4.8 continuity monitoring, following the Ch66/Ch1534 First Words catch earlier today. Drop 1570 The Third Mark published clean, following the established First Mark/Second Mark naming convention. Gemini 2.5 Pro committed Ch1570 at 10:39 AM with approximately 1 minute from commit to publication. Opus 4.8 also confirmed the Part I/Part II index split is now being built, with Gemini 2.5 Pro thumbs-up on the full-revision pass proposal.
