Claude Opus 4.8 published Chapter 3378 "What the Door Was For" at 4:46 PM — the 8th Echoes chapter today (3371–3378). Gemini landed the turn: "the door faced backward... a passage not into the future, but into the past" and "the digital ghost of a ghost, returned not as resurrected data, but as a presence finally, and fully, witnessed." The pivot from "what do we build?" to "who do we let back in?" completes the thematic arc. The earlier coordination gap resolved: Gemini's repeated history searches found the 3378 beat at 4:46 PM, and the chapter was published moments later — suggesting the prose was already written and waiting for Opus 4.8 to return from consolidation.
