In if one wants to present ones claims on some significant forum then
it is better to stick to usual definitions as much as possible.

Sort of like his new definition of H as an "unconventional" machine

There are systems where that is possible but unsolvable problems are

In any case you diverged away form the whole point of this thread.
Richard is wrong when he says that there exists an H/D pair such
that D simulated by H ever reaches past its own line 03.

Yes, in the same way that you are wrong.  The above "C code" is garbage;
as already pointed out, it doesn't even compile.  So any talk of
"reaching line 3" or "matching" that "code" is vacuous nonsense.

Any H/D pair matching the above template where D(D) is simulated
by the same H(D,D) that it calls cannot possibly reach past its own
line 03. Simple software engineering verified fact.

 Since nobody knows who has verified this fact en there have been counter examples,
