What have I overlooked ?

Probably the best way to think about this is Ranger is a module that can
be used by various passes. So the Ranger dumps will be in the pass
dumps for those passes which utilize Ranger.
The heaviest user is vrp and if you wanted to see what ranges Ranger
discovered, the vrp dumps are a good place to look.
