Nice! I was just implementing this for CA state bills.

Is the parsing/uploading code shared somewhere else?

Definitely the kind of idea that would have been below my activation energy pre-Claude.

I think this approach should be standard, I have always wondered why the source of truth for these documents is not moved to a repo like git.

my first reaction cynically would bet that government really doesn't want the people to know exactly what the laws are. a more generous reason would be nobody in law is truly technical enough to understand it let alone implement it.
