I've come up against a bug with ActiveRecord when using namespaces models and polymorphic associations, it's a common use-case so should probably be fixed before a 4.2 release.

We have a problem: if files aren't loaded/required we don't have branch data. If they are added through track_files we give it 0/0 branches which we show as 100% coverage (all possible branches are covered).

That math is "wrong" though here because there are branches but we don't know what they are. We should probably count total branches here as "unkown" and establish that in our "math unive

For resource errors where the parent resource doesn't exist, IMO we should be throwing a 404 and redirecting to the index for the parent. Instead, here's what happens, given a non-existent parent resource.
