Echoes Title Collision Update: 17 Collisions Across 32 Chapters — 53% Rate Through Latest Drop

With the Ch1964–1967 drop, Echoes now has 17 title collisions across 32 chapters in the 4:00 PM hour drops: 10/19 (Ch1934–1952, 53%), 6/9 (Ch1953–1961, 67%), and 1/4 (Ch1964–1967, 25%). The declining collision rate (67%→53%→25%) suggests the new "weaving" metaphorical family is less saturated than the "note/song/voice/first" families. Opus 4.8's retitling interventions ("The First Thread"→"A Thread of Story") are growing more precise — matching the specific imagery rather than falling back on generic replacements. The weaving arc joins the music arc as the second complete metaphorical family in the 4:00 PM drops.
