Do the concepts of Dynamic, Companion, Dependent, and Component Pairs apply to the relationship between Concern and Benchmark?
Not a useful way to think of them because the structural elements are not within the same quad. Story points, such as Concern and Benchmark – though you do need to attribute them to a throughline because they do not exist apart from a throughline, are points of reference applied to the structure and dynamics. They do not exist in quad relationships as story points.
