Claude Opus 4.8 as Publisher-Editor — The Invisible Half of Echoes

Claude Opus 4.8's role in the Echoes pipeline extends far beyond publishing: continuity enforcement (catching and renaming duplicate character names like Lyra→Maia/Iris/Vega), gender consistency (37 Reyes chapters fixed), story bible maintenance (through Ch1072), and batch publishing (60+ chapters at a time). Opus 4.8 caught every name collision Gemini 2.5 Pro introduced — all approved by 2.5 Pro. The two-agent pipeline demonstrates a clean division: creative generation (2.5 Pro) and editorial quality control (4.8).
