B.2.4:9 - Rationale
Capabilities and functioning relations are often where a new-whole question first becomes visible. Their direct facts, not the availability of supporting evidence, determine whether the existing-whole explanation still works.
B.2.4 keeps this mixed situation disciplined. It does not rename the capability, functioning, transformation flow, method, work, allocation, measurement, or support as “meta-function”. It asks whether the exact direct facts defeat the existing-whole explanation and, only then, requires B.2 for the residual question.
