The coding agent was pretty good at coming up with heuristics for matching - even more than the dozen I suggested from domain experience. And it used some of them sensibly for blocking, too. I'm sure I could get it to perform a little better and a lot faster with more agent wrangling. I did consider using the heuristics just for blocking, and letting a local LLM do the actual evaluation, but if Jev or Jev-like models work as advertised, maybe we can have the best of both worlds.

Thanks for the link, it is an interesting topic.
