Is not what I asked about. I asked about the behavior of D
when executed directly.
Off topic for this thread.
Yes, HHH is off the topic of deciding halting.

No it isn't, not if it is the definition of a PROGRAM.

558bec6872210000e853f4ffff83c4045dc3 as an input to HHH is
different than these same bytes as input to HHH1 as a verified
fact.
What does "specify to" mean? Which behaviour is correct?

How does HHH emulate the call to HHH instruction
The semantics of the x86 language.
Right, which were defined by INTEL, and requires the data emulated to
be part of the input.
It is part of the input in the sense that HHH must emulate itself
emulating DDD. HHH it the test program thus not the program-under- test.
It is part of the program under test, being called by it. That's what
you call a pathological relationship.

HHH is not asking does itself halt?
Yes it is saying "I can't simulate this".

It was encoded to always halt for
such inputs. HHH is asking does this input specify that it reaches its
own final halt state?
Which it does (except when simulated by HHH).

Is it guessing based on your limited input that doesn't contain the
code at 000015d2, or
Is it admitting to not being a pure function, by looking outsde the
input to the function (since you say that above is the full input), or
Are you admitting all of Halt7.c/obj as part of the input, and thus you
hae a FIXED definition of HHH, which thus NEVER does a complete
emulation, and thus you can't say that the call to HHH is a complete
emulation.

How we we determine that DDD emulated by HHH cannot possibly reach its

Two recursive emulations provide correct inductive proof.
Nope, because if you admit to the first two lies, your HHH never was a
valid decider,

Except when doing so changes the input, as is the case with HHH and DDD.

Changing the input is not allowed.

I have already addressed your misconception that the input is changed.

No, it is YOUR misconception. The algorithm DDD consists of the function DDD, the function HHH, and everything that HHH calls down to the OS level.
We have already been over this.
HHH(DDD) and HHH1(DDD) have the same inputs all the way
down to the OS level. The ONLY difference is that DDD
does not call HHH1(DDD) in recursive emulation.
