You continue to stupidly insist that int sum(int x, int y) {return x

returns 7 for sum(3,2) because you incorrectly understand how these

What else is it missing that the processor uses to execute it?

No, DD halts (when executed directly). HHH is not a halt decider, not even
for DD only.

But the direct execution of DD is computable from its description.

But neither the "direct execution" or the "simulation by HHH" are "inputs" to HHH. What is the input is the representation of the program to be decided on.

When HHH computes halting for DD is is only allowed

It is only ABLE to apply them.

You can't pop any other execution trace from the input
to HHH(DD) than that.
You can't abort a halting sequence and claim that it does not halt.
You can't claim a incorrectly coded program to be correct only it does what its code specifies.
