With all the proper tools and materials, I am a professional, capable of soldering traces about as thin as a human hair.
And when it comes to carbon traces, we absolutely did use conductive paint to fix damaged traces. But now I’m more into automotive repair and just don’t happen to have any conductive paint in my home electronics repair materials.
All I was wanting was a good homebrew solution to properly patch a ~3mm damaged section of carbon trace, not some hack solution that’ll just end up wearing loose and having a bad connection within a few months of gameplay.
So I do not find your answer helpful nor professional.

Yup the wire is going to be more tolerant of flexing than the glue or a solder joint.

The crack is right next to the left analog stick, in a spot that will receive random pressure and mild board flexing while in use. Sure the plastic shell is still intact and all the supports are still there, but this particular spot is still a bit of a sensitive spot.
I’m all about the idea of a little piece of patch wire, but I want to actually adhere the patch wire to the trace with a conductive paint. I don’t want to just tape a piece of wire on it, only to have the wire micro-sliding back and forth and just wearing more carbon off the board over time.
And soldering is completely out of the question, you can’t solder to a carbon trace.

I’d fix the mechanical with epoxy and then use a small conducive screw tapped into the exoxy as a bridge.

While that idea sounds good on paper, the crack runs right by the edge of the button plunger, so the fix is gonna have to be about as flat as possible, and well adhered with conductive paint.
At least it didn’t crack directly under the button traces themselves, but it’s right next to it…
