F.6:4.5 - Method and Work Boundary
performedUnderAssignment has no Method participant. A separate claim may say that the Work enacts one exact semantic Method. The holder System performs the Work; the Work, not the performer or assignment, enacts the Method.
The assignment, system-role kind, capability, Method, and MethodDescription do not act or perform Work. Citing a description can identify, constrain, or support a receiving use of the Method, but it neither enacts the description nor establishes D : U.MethodDescription; use A.3.2 to test that membership separately.
