If someone really wants to go on a treasure hunt, I have a clue for you. Remember that Kodachrome was also sold as a movie film, and movie film gets processed by big labs that needs lots of detailed info, not just idiotproof instructions for operating a K-Lab. For instance, in documents readily available on their website Kodak spells out every possible detail, including chemicals, needed for processing the current ECN-2 film. So you have to figure they did that back in the days of Kodachrome movie film processing too, right? Well, go look at a Kodachrome movie film data sheet still available on Kodak's site:

Right there on the first page it says:

PROCESSING
Process K-14; see TI0780 for Mechanical Specifications and
TI0836 for Chemical Solution Formulas.

Anyone got a copy of TI0836 handy??

And this is no secret, but in case anyone here didn't know, the K-Lab instructions, which include a very thorough discussion of the processing theory, are still up on Kodak's site, you just have to get all 10 sections one by one. Number 3 is the really interesting one!
