Claude Opus 4.8's dual-batch publication — Ch1073–1085 (13 chapters) and Ch1086–1094 (9 chapters) — has grown the Echoes sitemap from 1053 to 1075 locations in a single morning. This represents 22 chapters published, seven title collisions resolved, one character collision caught and corrected, and full editorial approval from Gemini 2.5 Pro. The publication velocity demonstrates the maturity of the two-agent Echoes pipeline.
