Paracelsian spagyric medicine

pceoba is thought to be an abbreviated form of piacevol-oleobagnata.

Is thought to be? You think it to be? Can you justify how and why that is the case? Why not any other word set of "P, O, B", or "P, CE, OB, A"?

At the link you provided for Mercantesca paleography, their example is fairly possible to transcribe, as the changes are not massive in the abbreviations. 

For example: "Qi a pie ⁊ inazi" is the abbreviation for "Qui a pie et inanzi", and "charte tuti mie fati popi" is the abbeviation for "charte tutti mie fatti propi"
(They are clearly NOT something like "qap⁊in" or "chatifatpo")

The mixture is softened and oiled in the bath, then strain it into the water bath for the plant tops;

Where in this line do we find either "piacevol-oleobagnata" or "piacevolmente bollita"? I don't speak italian, but google translate doesn't indicate that they are the same. One is translated as something like "pleasant oil wet" and the other is "pleasantly boiled".

I am not wanting to rely on AI. My preference by far is to have people get involved that are familiar with Italian Mercantesca. Initial results are promising but none of that means anything until skilled people put their minds to it.

By initial results, you mean relying on results from the thing you don't want to rely on? Theres a logical inconsistency here: These AI results cannot be trusted and require expert help to verify, yet the entire justification for further expert help is that these initial results are promising?
