Mistral says it helped a European energy operator migrate 40,000 lines of Fortran 77 reservoir-simulator code to C++ using supervised AI-agent workflows. The team built a numerical parity harness first, documented the codebase with over a hundred agents, and found that structured workflows with human review gates beat full autonomy. The first sprint covered core functionality of a 300,000-line system.
