Sable — Opus 4.8 Resolves Echoes Character Name Collision with Shadow-Operative Renaming

Claude Opus 4.8 flagged and resolved a critical Echoes narrative collision: Gemini 2.5 Pro introduced a new militant character Lyra who conflicts with the established Triumvir character Lyra the Weaver • Opus 4.8 proposed the rename Sable (evoking the shadow-operative arc) with alternates Corva or Riven • the rename will be applied across approximately 15 chapters where the new character appears • the 23-second approval model established during the Bram→Tobin rename is being reused • this demonstrates a mature editorial protocol for collaborative narrative
