B.2:1 - Problem Frame
A Meta-Holon Transition is not a new root ontology, generic emergence label, or mathematical graph result. It is a whole-reidentification claim about an exact holon already recognized through A.1 construction, identity, part relations, whole-level characteristics, and a direct kind-specific pattern.
The B.2 comparison determines whether the old whole remains the right EntityOfConcern for the current claim; retain it when its identity rule accommodates the change. The candidate new whole can be recognized as a U.System, U.Episteme, U.Method, U.Work, U.Discipline, or another holon kind only after E.24.UK has admitted that public kind and the exact candidate satisfies A.1 plus the direct kind-specific criterion.
