For TREE(3), the section over {TREE(3)} (extend this section as needed) maps TREE(3) to 'undetermined' preserving our epistemic intuitions.
This is what they call assuming that which is to be proved.
Eh? I am not assuming that which is to be proved. The parity of TREE(3) is to be proved.
Have you proven it to be Odd or Even yet? I haven't. So how would you like me to represent or express the value of MOD2(TREE(3)) ?

You seem to believe TREE(3) has no determinate parity. That's wrong, if not flat out insane.
You seem to believe that TREE(3) has a determinate parity like 4 has determinate parity. That's wrong. If not flat out insane.
I can model/represent the value of MOD2(4) as 0.
If you don't want me to model/represent the value of MOD2(TREE(3)) as 'undetermined' then how would you like me to model/represent it?

But even if it turned out to be true ... you used that fact in your alleged "proof" of that fact. So the proof is circular.
What is it that has to "turn out to be true"? The fact that the value of the expression "MOD2(TREE(3))" is undetermined?
It's obviously true. Nobody has any clue how to determine its value!

Are you implying that TREE(3) is not an integer?
More insanity.
Of course you can take refuge by noting that set union is not necessarily disjoint. But why else write it that way?
Oh no! A frivolous step! Are you running out of things to nitpick?

Curious about one thing. Do they teach this watered down version of sheaves to CS majors these days? Interesting if true.
They don't teach it to CS majors. Distributed Systems Engineers figured out that the line between theory and practice is blurred because... "In mathematics, a sheaf is a tool for systematically tracking data attached to the open sets of a topological space and defined locally with regard to them."
That sounds like fancy mathematical jargon for a control plane between interacting interacting systems.

ps -- Are you implying that TREE(3) is the ONLY integer with indeterminate parity? All the others have determinate parity? Is that your claim in this silly "proof" which doesn't prove anything?
Eh? I am painting in broad strokes here. TREE(3) is but one of many integers for which you can't determine which of these
parallel computations wil halt:
A: (MOD2(X) == 0) halts ONLY if True
B (MOD2(X) == 1) halts ONLY if True
You want me to prove that I have neither a halting proof for A nor a halting proof for B ?!?!? The fuck?
The above holds for any integer-encoding for which I can't obtain a full expansion. You know - parity is nothing other than the least significant bit.
