Ask Slashdot: How Would You Deal With A 'Gaslighting' Colleague?

An anonymous reader writes: What's the best unofficial way to deal with a gaslighting colleague? For those not familiar, I mean "bullies unscheduling things you've scheduled, misplacing files and other items that you are working on and co-workers micro-managing you and being particularly critical of what you do and keeping it under their surveillance. They are watching you too much, implying or blatantly saying that you are doing things wrong when, in fact, you are not...a competitive maneuver, a way of making you look bad so that they look good." I'd add poring over every source-code commit, and then criticizing it even if the criticism is contradictory to what he previously said.
The submission adds that "Raising things through the official channels is out of the question, as is confronting the colleague in question directly as he is considered something of a superstar engineer who has been in the company for decades and has much more influence than any ordinary engineer." So leave your best suggestions in the comments. How would you deal with a gaslighting colleague?

Carry voice activated recorder at all times, for those Orders that never quite jib when the review starts
Order from Amazon "Getting even, the handbook of dirty tricks", use it, but leave out the juvenile superglue gags
DO use the lemon juice chair spring squeek enhancer trick, really, REALLY gets under the skin of any Type "A"
A good old fashioned degausser can do wonders with their latest project, and leave no trail even if they have surveillance in the office itself (note, max range for an obfuscated hard drive is about 15 feet)
Fun things to do with their email, assuming you put in the time to break their sign-in.
Remember, old age and guile beats youth and capability EVERY time!
