You're in luck, someone recreated the constitution in git with the history of edits

Edit: just noticed the dates aren't accurate, but still interesting and the authors are accurate

Can git do pre-1970 dates?

The file/wire format can, but the official implementation doesn't handle it well. There is some work in progress to make it work, for this kind of historical work.

There is a project doing exactly this for German law.[1] I also once cobbled together a rather primitive Python script which commits Swiss federal law as MD-file into a repo through GitHub actions.[2]

Yes. We need git-blame here.
