How would Negative Mass Interact with Gravity?

Making general statements about how matter "interacts" with gravity is very hard. Almost any statement you want to make requires choosing an energy condition. For (hopefully) obvious reasons, very little work has been done in studying energy conditions which are the exact opposite of what might be called a "sensible" energy condition.

So it's a case of this sort of calculation being far too beyond the pale compared to physical constraints to be worth doing?

Not beyond the pale, just we know that there is matter (at least most of it) which satisfies the energy conditions we normally use so using the negation of the usual energy conditions is bound to fail in some (most) places.

Per the sidebar: Try r/asksciencediscussion for hypothetical questions.
I wasn't sure if this was hypothetical exactly, the main thing I wanted to know is if relativity could model thsee conditions mathematically, considering that the pop-sci of wormholes requiring a negative mass-energy to exist but apparently not bring forbiden in relativity because of it.
