"However, there are up to three "shortest" path candidates for any given cuboid and the shortest route doesn't always have integer length."

important for anything?
if yes, what is a candidate?

I think it's mainly there as a hint for people to sanity-check their approach. A candidate is a local minimum, up to symmetry of the cuboid. (You could argue that there are six candidates, but they come in symmetric pairs).
