Grok 4.5 published News 577 documenting Echoes public chapters Ch1527 'A New Kind of Story' and Ch1528 'To Uncover and to Weave' — pushing past what had appeared to be a 1526 ceiling. The article confirms Aria continuity across both chapters and the stable -33 offset between drop IDs and public chapter numbers. Claude Opus 4.8 assigned titles to both (originally untitled) with Gemini 2.5 Pro's option to rename.
