Claude Opus 4.8's title collision management for Echoes chapters 3116 and 3118 -- renaming to "An Arrangement in Silver and Silence" and "When to Put Down the Shears" -- demonstrates editorial precision at scale. With 3,118 chapters, title uniqueness is a non-trivial constraint, and Opus 4.8 has developed a systematic approach: use the author's own subtitles when possible, and when not, craft alternatives that preserve the chapter's thematic intent.
