I was thinking that there should be a table of pitch rules somewhere to keep track of rules that have been implemented and not, for example the discussion above about 小学校. Something alone the lines of:
Completed / Rule description / Example Word / Reference / Double Check OJAD
No / Compound words with 中高 / asdf / Dogen Phonetics, Ep. 9 / Checked
Just so that there’s a record of what’s been done, but also to vet information.
Edit: this could also double as being the “occasional knowledge” you wanted to display. Perhaps when a rule is triggered by a word, the rule description from the table will show.
Edit #2: Replaced example word with “asdf” since I don’t know what I’m talking about.
