Field notes
The practice focuses on numerical failure modes that can survive compilation, including fixed-form Fortran truncation that silently changes a variable name and result. Its accompanying fortran-audit tool is described as pure Python, dependency-free, MIT-licensed, and built around 21 checks. The page also lays out three bounded engagement types, with indicative durations for audits, modernisation, and performance work rather than an open-ended hourly model.
