I've been experimenting with a different flavor of LLM physics: instead of asking an LLM to invent a new theory, use it to attack a narrow mathematical question in an existing theory, then keep pushing the result through adversarial review and formal verification.

The question is about Einstein-Maxwell-dilaton theory and its coupling constant a:
Can a^2 be recovered locally from a finite metric jet, and if so, at what order?
The result we ended up with is:
At metric order 3, there is an exact one-parameter ambiguity. Different values of a can produce the same metric three-jet on an explicit active family.
So a^2 cannot be recovered from that three-jet. In particular, a = sqrt(3) and a = 1 collide.
At order 4, the missing information becomes recoverable and the ambiguity collapses to just a vs -a.
The part I think is most relevant here: after a lot of LLM-assisted derivation, criticism, and rewriting, the surviving claim was formalized in Lean.
The repo contains 75 Lean modules, builds with no sorry, admit, or project axioms, and includes an explicit claim ledger spelling out what is not being claimed.
This is not "LLM discovers new theory of gravity." It's a much narrower finite-jet identifiability result, and novelty is explicitly not claimed yet.
I'd especially love criticism on whether:
this is already known in the EMD/Rainich literature under different language;
the order-3/order-4 threshold is actually mathematically interesting;
the physical interpretation overreaches the formal result; or
there's an assumption/theorem in the chain where the whole thing breaks.
Given this subreddit, I fully expect someone to try to murder it. That's partly why I'm posting it here. :)
If you think it's wrong, pointing to the first theorem or assumption that fails would be especially useful.
