Answered: Overfilling pneumatics

Will the 100-psi limit for pneumatics be strictly enforced at worlds (teams risk a dq/other things if they are caught filling at, say, 120) or will it be a do-it-at-your-own risk thing? If officials were to check pressure on a pneumatics kit, will teams be permitted to fill in more air, since the process of checking pressure usually uses a significant amount of air ?

Yes. Teams who are caught overfilling their air tanks risk being disqualified for their upcoming matches and beyond.

If in the process of a pressure check, the pressure of your system is bled below 100 PSI, you will be given the opportunity to recharge to 100 PSI.
