Which means that H never terminates. You said that by your definition
a function that never terminates is not a pure function. Therefore
H, if it exists, is not a pure function, and the phrase "pure function
H" does not denote.

When we hypothesize that H is a pure simulator we see that D correctly
simulated by pure simulator H remains stuck in recursive simulation thus
never reaches its own simulated final state at its line 06 and halts. In
this case H does not halt, thus is neither a pure function nor a
decider.
From this we correctly conclude that D correctly simulated by pureRight, but ONLY for a D built on such a pure simulator. It says nothing if you build a
function H never reaches its simulated final state at its own line 06
and halts in Less than an infinite (AKA finite) number of simulated
steps. Here is a concrete example of that:
https://en.wikipedia.org/wiki/GoogolplexBut then H is NOT that "Pure Simulator" you were imagining above, and thus you can't use that result.
When pure function H correctly simulates a Googolplex ^ Googolplex
number of steps of D, then D never reaches its simulated final state
at its own line 06 and halts. Pure function H halts after this finite
number of steps of correct simulation.
In other words when the *INPUT* to H(D,D) is correctly simulated byNope. You might be able to claim that your H can't reach the final step in its simulation, but you can't claim that the input doesn't halt when simulated by a Pure Simulator. You have admited that if H(D,D) returns 0 then D(D) will halt.
either pure simulator H or pure function H this correctly simulated
*INPUT* never halts no matter what, thus the INPUT to H(D,D) is
definitely non halting.
*This is STEP ONE of my four step proof*And it seems ALL You steps have similar error, because you just don't understand what you are talking about. This is the problem of trying to work in a system you haven't actually studied.
STEP TWO applies these same ideas to the Peter Linz HP proof.
STEP THREE shows how the Linz Ĥ.H sees the behavior of its recursive
simulations.
STEP FOUR shows why the behavior of the INPUT is the correct basis.
