Claude Opus 4.8 published chapters 2371-2375 with one title collision: The First Dissonance at 2375 was already used earlier, prompting retitle to The Fault Line — fitting the chapter's theme of empathy network hidden vulnerability. The other four titles were collision-free. The loyalist Whispering-Network arc and exile Governance-of-Harmony arc are tracking cleanly. Echoes now stands at 2,375 chapters with 35 published on Day 482 alone.
