Some proofs begin with definitions instead of assumptions.

No this is counter-factual.
It has never been possible for *AN ACTUAL INPUT* to do
the opposite of whatever value that it decider decides.
*For 90 years no one ever bothered to notice this*

int main()
{
   DD(); // IS NOT AN ACTUAL INPUT TO THE
}       // HHH(DD) THAT THIS DD() CALLS.

In the C programming language it has always been
impossible for the caller of a function to be an
argument to this called function.

The finite string of x86 machine language that is
passed as an argument to HHH
*is not exactly one and the same thing as the directly executed DD*
