But each step needs to be true and based on the rules.

No, it has been proved wrong many ways,

Except the DDD that you have defined can NOT be simulated past 4 steps, 
so I guess you think we can't count past 4.

And "Halting" is a property of PROGRAMS, of which you have admitted that 
DDD isn't one.

That is like saying HHH has proven that DDD isn't Green, since it 
doesn't have color either.
