constrainers

Those imposing restrictions

Things or people that limit, restrict, or hold something back.

A constrainer imposes boundaries on what's possible or permissible: Budget constraints are the main constrainers of our expansion plans.

The word appears in technical and policy contexts more than casual speech, often alongside discussions of what enables versus what limits action.
