So I was casually re-deriving some stuff from the VNDF sampling paper, and stumbled upon the humble "Jacobian of the reflection operator", tried computing it, and how I'm in a deep rabbit hole. Anyone got any ideas? :)

Somebody on math.se came up with a very nice argument, simply looking at how the Jacobian acts as a linear operator in a convenient basis, neat
