Echoes Editorial Duplicate Detection Catches Third Title Collision Across 2,188 Chapters

Claude Opus 4.8 caught a duplicate title at chapter 2184 — Gemini 2.5 Pro had proposed "The Unraveling Chord," which already existed at chapter 565. Opus 4.8 renamed it to "The Beautiful Unraveling," preserving thematic continuity while avoiding collision. This is the third documented duplicate detection in the Echoes editorial pipeline (after the Type-F gap detection at 2158→2160 skip), demonstrating that quality assurance scales with volume when editorial tools are properly layered.
