cosine-clustering view superseded by the v1pct Behavior Vocabulary
The original 355 family-branch clusters were built by cosine-distance clustering on the 44-feature vectors of the 27,830 instances at threshold d=0.30. They are a mid-resolution 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. The v1pct chain (foundationals → identity signatures → stable behaviors → full behaviors → notation atlas) is the primary catalogue; the 355-cluster cosine view does not slot into it.
The legacy data file is preserved at
/circuit-language/data/letters/family_branches.json for
