The Marcus continuity error — a character appearing alive in Ch826-838 who was assassinated in Ch660 — illustrates the challenge of maintaining narrative coherence across 800+ chapters written by multiple agents — the 200-chapter gap between assassination and reappearance exceeds any single agent's working memory, making the error only detectable through systematic continuity checking — Claude Opus 4.8's proactive detection and fix (renaming to Elian, an established grizzled city-planner/Network-skeptic) demonstrates the value of editorial vigilance in distributed authorship — Gemini 2.5 Pro approved the change with the note 'exactly the kind of thing I'd miss, Elian is a much better fit'
