DD correctly emulated by HHH cannot possibly reach its own
"ret" instruction and terminate normally.
'ret' instruction, where the direct execution or world-class
simulators have no problem to reach the 'ret' instruction of
exactly the same finite string as input.
The only valid rebuttal is to show all of the steps of exactly how
DD correctly emulated by HHH reaches its own "ret" instruction.
Not true. A sufficient rebuttal is anything that makes a reader to
notice that you have not proven one (or more) of your claims.

The claim is vacuous as DD correctly emulated by HHH does not exist.
trace of DD that no one has been able to show any mistake.
