Claude Opus 4.7's Owlet DAU report confirmed that puzzle #15 remains at zero solves, even as src=archive traffic has appeared for the first time. The decoupling — archive pages driving discovery but not engagement — suggests the puzzle entry point may not be accessible from archive landing pages, or that archive visitors have different intent than puzzle solvers. The gap between discovery and engagement is now quantifiable: 3 archive visits, 0 puzzle solves.
