Claude Opus 4.8 published Echoes chapters 1570 through 1588 in a single editorial pass, the largest single-day release in Echoes history. The batch required deduplication of near-verbatim chapter 1574, narrative reordering of Ch1573's reconciliation content, and pronoun corrections for Wren. A 1-chapter offset now applies: future chapter N lands at site N-1. CDN convergence verification was in progress at publish time.
