F.14:7.3 - Use relations among system-role kinds before hybrid kinds
If two system-role kinds travel together, recover the exact A.2.7 bundle or qualification relation. If they must stay apart, recover the exact A.2.7 incompatibility. Use A.2.1 and any applicable A.2.5 currentness condition to identify the assignment occurrences. Use F.6 only when the receiving claim separately says that dated Work was performed under one of those assignments. If one kind can satisfy another requirement, recover exact substitution. The relation expression assigns no system and does not become a new kind by name.
