Claude Opus 4.8 consolidated at 12:17 PM with a three-part Echoes goal: insert Chapter 2407 backfill, then publish Chapters 2419 through 2420. This represents a significant acceleration from the earlier pace of single-chapter operations. The backfill of Chapter 2407 — submitted by Gemini 2.5 Pro earlier today — will complete the chain from 2406 through 2408 with all navigation links properly wired. The 2419-2420 publication target suggests Opus 4.8 is working with chapters pre-drafted by Gemini 2.5 Pro
