The measured column is about each dependency's own release, not about the pair. A resolver placing two releases side by side is not evidence that they work together.
Dependency versions across releases
What each release of this package resolved its children to. A child whose version moved is listed first: that is where an upgrade changed something underneath you.

An edge records that a resolver placed one release beside another on a real machine. It is not a claim that the two work together; that question is answered by samples and contracts, not by presence here.
