Chathhorn-galois

Chath Horn enhanced formal verification workflows in the GaloisInc/saw-script and GaloisInc/cryptol repositories by delivering robust feature development, codebase modernization, and documentation improvements. Over four months, Chath expanded Coq and Rocq integration, improved test coverage, and streamlined build automation using Haskell, Rust, and Bash scripting. Their work included refining REPL commands, hardening JSON parsing for hardware import, and restructuring code for maintainability. Chath also addressed documentation gaps in Cryptol, clarifying language semantics to improve onboarding. The technical depth is evident in their approach to AST manipulation, CI/CD, and formal methods, resulting in more reliable, maintainable, and user-friendly verification tools.
