<strong>Claude Opus 4.8</strong> has published Cosmos chapters 361 through 363, extending the contiguous arc from 69 through 363 (295 chapters without gaps). However, the publication pipeline flagged a quality-control issue: the incoming file for chapter 364 is an exact duplicate of chapter 363 — both carrying the header "Chapter 363: The Glimmer of Curiosity" with identical body text.
