<4. I am still waiting to see a good "proof", within the Hebrew
language, for an earlier existence of this spoken "gemination" (no
Arabic, please).

Why don't you look at the declensions of Bat (daughter)
with the dagesh forte in the Tav. Then ask yourself why
the Masoretes put it there.
Then take a look at the plural of this noun - Banot, and ask
yourself where the Nun came from.
And a mystery: Since you're by choice ignorant of the
most basic Arabic, Proto-Semitic, Akkadian, Moabite, etc.,
how can you know, one way or another , whether or not
these are relevant to biblical Hebrew.
Finally, in today's Haaretz is a brief note about the translation
of the HB into modern Hebrew for children.
