HHH correctly predicts that a correct and unlimited emulation of DDD
by HHH cannot possibly reach its own "return" instruction final halt
state.

A complete emulation is not required to correctly predict that a

What do we care about a complete simulation? HHH isn't doing one.

Lol, dude...  I mentioned nothing about complete/incomplete simulations.
But while we're here - a complete simulation of input D() would clearly halt.  You have seen that yourself, e.g. with main() calling DDD(), or UTM(DDD), or HHH1(DDD).  [All of those simulate DDD to completion and see DDD return.  What I said earlier was that HHH(DDD) does not simulate DDD to completion, which I think everyone recognises - it aborts before DDD() halts.
Mike.
