What about ‘sanction’?
Yes. It can be a noun or a verb.
Legally, it's both:
1.) a "provision of a law enacting a penalty for disobedience, or a reward for obedience"
2.) "the penalty or reward."
You could argue – lawyers love to argue, & say "moot" – that it's unambiguously a provision, but with two opposing effects. That's hairsplitting.
Let's consider sanction to be a quantum noun/verb with two possible opposite effects, depending on the context.
Thank you for that example.
