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.
| Library | 3.0.6 | 3.0.5 | 3.0.3 | 2.0.119 |

Moved: 1 · unchanged at every release: 2
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.
