If simulating halt decider H correctly simulates its input D
until H correctly determines that its simulated D would never
stop running unless aborted then
H can abort its simulation of D and correctly report that D
specifies a non-halting sequence of configurations.

DDD is correctly emulated by HHH according to the x86
language semantics of DDD and HHH including when DDD
emulates itself emulating DDD
*UNTIL*
HHH correctly determines that never aborting this
emulation would cause DDD and HHH to endlessly repeat.

But H determines (correctly) that D would not halt if
it were not halted. That much is a truism.
