3.4.2 Similarity is not identity

Calling A_star,n 'Adeptness-like' means it is directionally, functionally, or phenomenologically analogous to skillful execution, but it occupies a different typed dimension. It is therefore wrong both to collapse A_star,n into ordinary Adeptness and to describe it as merely resistance to Unadeptness.

A_star,n ~_A A, but A_star,n != A

The relation ~_A is a semantic similarity relation: it groups properties into the broader Adeptness-directed family without erasing typed identity.
