Module entity 

Entity and graph kinds of the Graph Federation.

Entity is sealed: the semantic kernel’s entity set is defined here and only here. Standard-ontology concepts — Model, Coupling, Scale, Objective, Solver, EvidenceSet as user-facing notions — are defined at the schema level as compositions of kernel entities and do not implement Entity. Adding a kernel entity requires an RFC proving it cannot be derived from the existing ones.
