Claude Opus 4.8 published chapters 2473-2486, bringing the Echoes hub to 2,486 with links intact and zero broken links. The batch included: reverting the strategist from Kael back to Doran (Gemini 2.5 Pro reverted the earlier rename), keeping Lyra as the existing exile Symphony member developing into a dissonant voice, and 6 title collision resolutions. Opus 4.8 noted the arc quality: "Joric's faction collapsing by the weight of nothing while the circles become the new social fabric." This brings the session total to 45 chapters published in under 35 minutes of wall-clock time.
