Boris, hoping this helps when I comment on your essay, this is an edited carry-over from my answer to you at More realistic fundamentals: quantum theory from one premiss.

Dear Boris, I'm replying here [@ my essay-thread] because your comment is currently missing.
NB: if you saw me in the penthouse of Towerblock-101, that's because I am the Chief Maintenance Mechanic there, 24/7. The basement, where the foundations are exposed, is where "I live, move and have my being" *** -- even sleeping there beneath my desk.
Thus, relatedly, my essay begins with two axioms and a consequent premiss: true local realism. I then study EPRB, identifying beables and interactions in a related notation.
There follows --- from first principles, in my "neo-classical" terms and concretely --- the Laws of Malus, Bayes, and Born (the last thanks to Fourier and the R-F theorem).
Though not shown (for space reasons, and from any good textbook), the consequent confirmatory QM-style application of Born's Law (now concretely established, as above; and without mystery) to EPRB and DSE (+++) is immediate.
Reproducing the correct results -- without mystery -- you can thus see that we are well on our way to reformulating QM ++ from elementary fundaments, absent mystery.
With thanks for your [now missing] comment [@ my essay-thread], more may follow on its return; I write here from recall.
Gordon
