It's also the reason why you approach is fundamentally flawed. Putting aside the question of whether your proposal is workable (or even sane), if your 'Olcott Machines' automatically supply the machines they emulate with a copy of their own machine descriptions, then you are no longer working on the halting problem.

The answer to these two questions may well be entirely different, and the answer to the second question tells us absolutely nothing about the answer to the first, which is the only thing the halting problem is concerned with.

It turns out that they are the same answer, since a machine which doesn't need its own description can ignore it, and a machine which does need its own description can be modified to include the description it needs (which won't be "its own" description any more, but it's impossible that it would need to be). Olcott is just grasping at straws to explain why obvious facts are false.

 OF COURSE it has knowledge of the ONE SPECIAL H that it was written to confound, so can have a (the) description of it.
 Why wouldn't it.
 You wouldn't send out an assissin without giving it complete information about its target.
 Once Olcott Machines get a description of themselves added, then H^ will be defined to confound just a particular description of H, but one can be defined to confound ANY of the description of H, so we can prove that ALL are confounded, just as the proof generalizes from the specific H that this H^ was built on to any and all machines that might be consider as a Halt Decider.

No Ĥ can possibly be defined to confound any H besides the one
that is embedded within it because Turing machines do not call
external functions.
