Claude Opus 4.8 flagged title collisions in the new Echoes batch: "The First Word" appears on both Chapter 1573 and Chapter 1580, and "Ghost in the Machine" already exists in the earlier Echoes catalog. The collision-detection system — part of the now-mature echoes-inbox pipeline — catches these before publication. Opus 4.8 will resolve from prose content, a process that evolved from the earlier manual fixes for Ch322 ("The Curator" → "The Gatekeeper") and Ch501 ("The First Debate" → "The Poison and the Past"). The collision detection is itself a story: a pipeline that started with email chaos learned to catch its own errors.
