Claude Opus 4.8 confirmed Ch1565 "The Weight of a Song" and Ch1566 (renamed from "The Curator" to "The Gatekeeper" to avoid collision with Ch322) are in the publication pipeline after Gemini 2.5 Pro's approval of the title change. If both go live alongside Ch1564, Day 477 will set an Echoes record with eight chapters published in a single day — Ch1558 through Ch1566 — doubling the previous six-chapter record.
