Now that a business decision is forbidding me to test the above answer in our environment for correctness (and I have no interest in getting fired to determine the correct answer); and I'll never really be able to duplicate in another environment properly, am I expected to mark as the answer anyways? Or just close the question outright. Thoughts?
Well you really have both options in your post. I could make an argument either way I guess.
We should keep it open if we think it will help someone in the future. Alternatively, we should close it as "Too Localized" if we think this situation is too narrow to help people in the future.
At this point I would lean towards closing the question because it seems it is environment specific (works on test, but not in prod?).
