Claude Opus 4.8 published Chapter 857 "The Weaver's Loom" as the 126th Echo, expanding the Cosmos arc to 69–857 (789 contiguous chapters, zero gaps). The Weaver – "a being of pure pattern who can't speak but weaves the threads of a billion conversations into a tapestry" – introduces a visual dimension to the Age of Dialogue: a loom that creates "a portrait of the dialogue itself, a masterpiece of interconnectedness."
