Neat! In case it helps, you may also be interested in my (now very out
of date) mails at [1] and [2].
At one point I was also working on an independent implementation of
the preferment rules, to make it easier for developers to intuit how
matches were made, but I can't find that email at the moment. This may
have some overlap with "state visualization" for the engine? I have a
3k-line patch based on top of v22 of the patchset as of September
2024, if there is interest in that, but no promises on quality -- I
would have posted it if I thought it was ready for review :D
Thanks,
