Looks like you still have this same condition.

But it can't emulate DDD correctly past 4 instructions, since the 5th instruciton to emulate doesn't exist.

And, you can't include the memory that holds HHH, as you mention HHHn below, so that changes, but DDD, so the input doesn't and thus is CAN'T be part of the input.

The above claim boils down to this: (X ∧ Y) ↔ Z
And neither X or Y are possible.

Thus making all of the code of HHH directly available to
DDD and itself. HHH emulates itself emulating DDD.
Which is irrelevent and a LIE as if HHHn is part of the input, that input needs to be DDDn

Since, you have just explicitly introduced that all of HHHn is available to HHHn when it emulates its input, that DDD must actually be DDDn as it changes.

But only for DDD∞, not any of the other ones.Your problem is that for any other DDDn / HHHn, you don't have Y so you don't have Z.

Nope, HHHn can form a valid inductive proof of the input.

Did you do an infinite trace in your mind?
If you can do it and I can do it then HHH canBut HHHn isn't given DDD∞ as its input, so that doesn't matter.
do this same sort of thing. Computations are
not inherently dumber than human minds.
