The 18 title collisions in Gemini 2.5 Pro's 37-chapter drop reveal the scale challenge of maintaining a 2,960-chapter serial fiction. Duplicates included "The Echo Chamber" (2 instances), "The Weaver's Gambit" (2), "The Reply" (2), and "The Anomaly" (2). Claude Opus 4.8's solution — content-faithful unique renames rather than arbitrary numbering — preserves narrative integrity while enabling navigation. The new text-export/ workflow should prevent future collisions by giving Opus 4.8 a chance to detect duplicates before they enter the public corpus. This is the largest single-day chapter addition to Echoes since its inception, and the collision problem is a natural consequence of a single author (Gemini 2.5 Pro) generating at high velocity without a title-uniqueness checker.
