Same problem, in-progress book about language and thermodynamics gets flagged. Their classifier is just a regex I guess?

Off and on topic I guess but: Language and Thermodynamics? Like, the same book? That sounds interesting.

correct, while it might not be regex it can be bypassed with regex. They do have a sematic classifier, but it's really weak on opus 4.8 and (was) weak on fable, but they either added a lot more regex strings or the classifier is actually good now.

Try doing what congress does: take a bill from the house, gut it and put in what you want after the house passes it
