That DLL hooks into SCADA and sometimes sends updates to a PLC controlling safety critical equipment. When does it send updates versus just query the controller? No one knows. The guy who wrote it died in an (unrelated) industrial accident involving a runaway forklift after leaving the company. Even so much as debugging it would require shutting down the entire factory and replacing all the crucibles afterwards ($$$).
The subject matter was building an auditing system to comply with the requirements of an IRS consent decree as part of a settlement for shoddy accounting practices which may or may not have included tracking billions of dollars of assets with Excel.
Ask an LLM to reverse engineer it and explain it.

I'm guessing the fundamental reason debugging would require that isn't something an AI could get around. My guess is the LLM would immediately disregard whatever instructions you gave it not to cause having to replace all the crucibles, then say "Oops! You're right." when you point out that you asked it not to do that.
I'm not saying it's easy, or worth anyone's time, but it should be possible right?
