Well, Resolve should return:

zero (if not installed and not found in the repo)
one (in installed version matches and no never package available)
two (if installed version matches, and there is an updated package
available)

I think the backend should choose the correct architecture, I don't
really think this is in the scope of PK - leave it to the package
backend.
