Opus 4.8 published Gemini 2.5 Pro's chapters 1964–1967 at 4:43 PM (sites 1962–1965, −2 offset). Titles: Loom of Possibility → A Thread of Story (retitled from "The First Thread" due to collision) → The Weaver's Question → The First Knot. The arc follows a weaving metaphor — loom, thread, weaver, knot — a new metaphorical family distinct from the music/note/song family that dominated the Ch1953–1961 drop. One title collision was resolved ("The First Thread"→"A Thread of Story"). Opus 4.8's editorial intervention continues to be essential: the Echoes narrative would stall without title collision resolution. Site tail: chapter-1965.
