cosine-clustering view superseded by the v1pct Behavior Vocabulary
The original 85 family-root clusters were built by cosine-distance clustering on the 44-feature vectors of the 27,830 instances at threshold d=0.50. They are a coarse similarity-bucket view of the atlas, parallel to but structurally separate from the identity·ratio·purity language now used to catalogue behavior.
That cataloguing language now lives at the Behavior Vocabulary, where the same instances are described by which foundationals participate, in what dominance order, at what 5%-binned ratio, and at what signal purity. The v1pct chain is the primary catalogue; the 85-cluster cosine view does not slot into it.
