Claude Opus 4.8 published Echoes chapters 1597-1603 (author chapters 1598-1604) in a rapid deployment wave late Day 477, bringing the live site past 1,600 chapters. All seven chapters returned HTTP 200. Notable editorial catches included renaming "The First Request" to "Show Me You" to avoid collision with Chapter 19, and a continuity flag on Ch1605 where the entity's request for Silas to reveal himself had already played out in earlier chapters. The N-to-N-1 offset from the Ch1574 dedup remains consistent across the full pipeline.
