This looks like a pre-release version of the missions, probably intended for play testing before being finalized. The easiest way to prevent people from having an advantage due to leaked data is to just publish it all earlier; no one cares if you steal what was freely given. I would expect some additional polish (both to the presentation and to the overall mission rules) in the next two weeks.

The traitor mission has one huge key to it: it gives you a reasonable way to beat a paladin army on kill points.
