Review Comment:
I noticed while implementing that there are various invariants enforced in
different layers. This per se is not a problem if they weren't leaky, i.e. we
wouldn't pass the same data structures with different invariants through the
layers. This becomes apparent in unit tests where implied invariants have to be
modeled. One way to solve this would be to pass a different data structure,
e.g. not pass JobStatus to lower levels but only the update time / running time.
I think the check here doesn't hurt as it asserts an important invariant.
