Description
Old Coder implements an evidence-first development workflow designed for high-assurance software delivery. By surrounding implementation with executable specifications, types, and mutation testing, it creates a verifiable environment where the correctness of the code is proven by its constraints.
This approach is intended for AI agent builders and developers working in high-stakes domains—such as authentication, concurrency, or financial transactions—where line-by-line manual review is impractical or insufficient.
