I worked with contractor for a contractor who had AI write a script to update a repository (essentially doing a git pull). But for some strange reason it was using the GitHub API instead of git. The best part is if the token wasn't set up properly it overwrote every file (including itself) with 404s.

Ingesting json files into sqlite should only take half a day if you're doing it in C or Fortran for some reason (maybe there is a good reason). In a high level language or shouldn't take much more than 10 minutes in most cases, I would think?
