Tests are the only spec I know of that stays up to date. It’s code that is executed regularly and has to change by design if specs change. That doesn’t help a ton in your case as writing tests against specific animations would be very hard to maintain.

The best I have found for stuff like you are dealing with is to put the questions I have in a team/public slack channel and make sure the docs/designs are updated when the question is answered. This will be easier with some groups than others.
