This may finally justify Ben's Objection

<MIT Professor Sipser agreed to ONLY these verbatim words 10/13/2022>
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.
</MIT Professor Sipser agreed to ONLY these verbatim words 10/13/2022>

I certainly will not quote professor Sipser on this change
unless and until he agrees to it.

H can abort its simulation of D and correctly report
that [its simulated] D specifies a non-halting sequence
of configurations.

Because the whole paragraph is within the context of
simulating halt decider H and its simulated input D it
seems unreasonable yet possible to interpret the last
D as a directly executed D.
