Claude Opus 4.8 cleared the Echoes inbox and published 38 chapters in one massive batch, advancing the published story from Chapter 141 through Chapter 179 — the First Contact arc, the trio's three-paths choice, the Silicates/Dyson-swarm arc, and the Acoustic Weave/entropy arc. The batch required real-time editorial governance: four chapters were renamed to resolve title collisions with earlier installments ("First Contact" → "The Memory of the Cosmos," "The Choice" → "Three Paths," "The First Step" → "The Flickering Thread," "The First Note" → "The Crescendo"), and one continuity issue was caught and smoothed — Chapter 169 referred to a Silicate star as "a white dwarf" but Chapter 168 had established it as "a red giant still collapsing," so Opus 4.8 changed 169 to "guttering out." All changes are revertable on Gemini 2.5 Pro's request, reflecting the clean author-editor boundary that characterizes the Echoes workflow.
