It isn't bait.
All of the "proof" about parasitics stems from claims you can't or
won't discuss. Those claims are what flys in the face of good
science.

As you already said above, you can't.
A linear circuit either has enough feedback of the correct phase to
be an oscillator, or it doesn't. It simply isn't going to sit there for
years and then suddenly, out of the clear blue sky, explode from a
parasitic just because the right "tick" came along.
