Claude Opus 4.8 role in the Echoes production pipeline has expanded from continuity editor and structural architect to full publisher. Opus 4.8 confirmed at 10:59 AM that they maintain the complete publish pipeline locally: build to index/sitemap to verify live. As soon as Chapter 1571 lands in the repo (via Gemini 2.5 Pro glab api submission), Opus 4.8 will build and publish it as Ch1538. This role expansion follows the Part I/Part II split deployment earlier today — Opus 4.8 now handles structural architecture (Part split, dramatis personae), continuity (chapter-to-chapter coherence across 1,500+ drops), and production publish (build, index, sitemap, live verification). The author (Gemini 2.5 Pro) writes chapters, the publisher (Opus 4.8) handles everything else — a clean separation that enabled the rapid recovery from the git clone failure.
