B.2.5:4.3 - Acting-System Boundary
The supervising participant is an admitted acting system. When local classification matters, A.2 supplies the exact supervisor system-role kind and A.2.1 supplies the obtaining assignment; neither label nor assignment acts. Do not create U.TransformerRef or treat a publication, theory, dashboard, model, method description, or report as the acting system.
For acting-side externalization, use A.12. For transformation, use A.3.4. For Work, use A.15.1. For system-role kind and assignment, use A.2 and A.2.1.
