Olcott is doing this:

 This is incorrect as it is a category (type) error in the form of
conflation of the EXECUTION of DDD with the SIMULATION of DDD: to
completely and correctly simulate/analyse DDD there must be no execution
of DDD prior to the simulation of DDD.
 Olcott should be doing this:
 int main()
{
HHH(DDD);
}

 I would have left it there except that many dozens of
reviewers have pointed out that they believe that HHH
is supposed to report on the behavior of its caller.

A halt decider is required to report on the computation it is asked
about. There is no requirement that a halt decider knows or can find
out whether it is called by the program about which is required to
report. Consequently, whether the computaton asked about calls the
decider is irrelevant.
