Keep in mind that the association between source and target can be
represented in any of a variety of ways.

My current best understanding is that an arrow consists of a triple:

source, target, distinction

And the "distinction" part follows its own rules which depend on the category.

(In the above example, n was source u n was the target and u itself
was the distinction.)
