As far as I can see the only way to be absolutely certain is
-someone faints
-skysplitting
-character says it’s CoC
Even no touching is not enough cause that might be ACoA.
I’m (obviously) a Garp fan and I can’t even say I‘m 100% sure Garp used ACoC with Galaxy Impact. I think he did, but the lack of any fodder foaming at the mouth makes it uncertain.
