AHHHH refactor attack_vectors_spec; hopefully it now borders on understandiablity.  this deffy needs another pass from another human, as I had to make tons of spec helper methods to make the crazy setup make sense, but I think we are bordering on something that would let us write new tests in a sane way. whether all of these tests now make sense to test in the first place, that is another question all togther, as it was outside the scope of this refactor
