    Proven impossible for such an algorithm to decide H^ is
    non-halting:

    That you have never agreed to this proves that you are dishonest. >>>>>>>>

    And YOU don't understand that no ALGORITHM can detect this.

    Thus, YES, if your H that doesn't abort its simulation until IT
    can correctly prove the computation is non-halting, H^ will be
    Non-Halting and that would be the correct answer, but H can not
    compute that answer, and will be non-halting itself.
    Well that is a breakthrough.

    The correct halt status for embedded_H applied to ⟨Ĥ⟩ ⟨Ĥ⟩ is Ĥ.qn
    even if embedded_H cannot compute this correct halt status.

    Prior to this breakthrough both Ĥ.qy and Ĥ.qn were the wrong answer. >>>>>>


    Right, the correct answer is Non-Halting but NEITHER H or
    embedded_H can give it, because if they do, it becomes the wrong
    answer.


    When embedded_H is basing its halt status decision on the behavior
    pure simulation of its input then because the pure simulation of its
    input would never stop running when embedded_H transitions to Ĥ.qn
    it is necessarily correct because it is still true that the pure
    simulation of its input would never stop running.


    So if H IS a pure simulator, the correct answer is Non-Halting, but a
    pure simulator will never abort itself to give that. H FAILS.


    computation that halts
    ...the Turing machine will halt whenever it enters a final state.
    (Linz:1990:234)

    The fact that the input to embedded_H never reaches its final state
    whether or not its simulation is ever aborted conclusively proves that
    this input never halts therefore when embedded_H transitions to Ĥ.qn
    it is necessarily correct.


    WRONG, because the ACTUAL Turing Machine that is represented in the
    input WILL reach its final state,

    This is why I need an actual computer scientist to review my work.

    An actual computer scientist will understand that embedded_H does
    compute the mapping from these inputs finite strings ⟨Ĥ⟩ ⟨Ĥ⟩ to this final state Ĥ.qn on the basis that the actual input would never halt.
