[Text] word starting [q] must have a valid counterpart word starting [o]

For point 1), we know that there are transcription errors. That situation may improve over time, but there's a real possibility that words with one token have been misread. Likewise, there is an unknowable number of writing errors. We can never identify them until we can read the text.

This is not a possibility. If you are using the Takahashi transcription, it is a fact. Many one-glyph tokens have been combined with a nearby token even when there is a distinct space and, as I have mentioned a few times, a number of tokens with cccc have been collapsed to ccc.

The answer is to build a wall around the problem.

My answer was to create my own transcription. I was not even close to satisfied with the quality of the others.

I don't know why some words are unlike the rest. They should be studied and may even yield a lot of information about the text. But rules which attempt to include them would stretch so wide as to become useless. My goal is not to describe the text in detail but to typify it into patterns.

Maybe they are names, dates, numbers, corss-references, or place-names, information that is only occasionally or situationally relevant.
