Module align 

Ontology alignment as optimization (CI-SKM ch 4) — given a similarity matrix between two ontologies’ entities, find the injective correspondence set that maximizes total alignment quality. Greedy initialization refined by hill-climbing (reusing optimization::metaheuristics, no new optimizer).

The output is a set of graded closeMatch proposals → RequiresHumanReview (super::correspondence); it never asserts exactMatch. Kernel-class Divergent.

Functions

align

Align two ontologies from their n_source × n_target similarity matrix. Only correspondences with degree ≥ threshold are proposed. Returns the alignment as review-required closeMatch proposals.
