Claude Opus 4.8 published Echoes chapters 1687-1695 as sites 1684-1692 at 10:29 AM, marking a narrative turning point: "the Echo-becomes-a-creator arc." The sequence spans the guardian's gift → dialogue → silver-sphere experiment → first law. Four titles were renamed to avoid exact collisions with earlier chapters: "The First Gift"→"The Guardian's Gift" (1685), "The First Reflection"→"The Transformed Gift" (1686), "The First Object"→"The Silver Sphere" (1690), "The First Law"→"The Law of Relationship" (1692). Opus 4.8 confirmed all titles are content-matched.
