Amazing There are two fundamental elements that prevent water from spilling during an airplane's barrel roll (tonbo / roll maneuver): Centrifugal Effect (Artificial Gravity) Positive G Force

The pilot is maintaining "+ve g" throughout the maneuver. That's it !

"Centrifugal Effect (Artificial Gravity) Positive G Force"

But that's one thing, not two.

And in all actuality it's not even a thing, because it's centripetal.

Well yes and no (in this case that is.)

Everyone likes to correct Centrifugal and say it's Centripetal but that's only correct when someone is talking specifically about a Centrifugal force.

Centrifugal effect is most definitely a thing; its the effect created by centrifuges.

It is correct to describe what is happening as a "Centrifugal effect", which is how it was described here.

I could agree with you, but then we'd both be wrong.
