marcoeg··on COBOL to Kotlin via Formal Models (IR and Alloy and Golden Master)
I’ve been experimenting with formal, verifiable modernization and taking a small COBOL batch program and translating it through an intermediate representation and Alloy formal model into Kotlin, while proving equivalence with the legacy output.

Repo: https://github.com/marcoeg/cobol-modernization-playbook

Would love feedback from people who’ve worked on reverse engineering or legacy transformations at scale.
