Describes / governs relation type
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
Directed semantics
Every direct mAtlas edge is an authored source → target assertion of this type.
Machine-readable record
/data/latest/relation-types/describes-governs.json provides this definition and the IDs of every direct relation of this type.
A path may traverse an edge backwards for connectivity, but that never reverses the authored source-to-target assertion.
