How to effectively debug when you no longer understand the code
Summary
The article explains Hibana, a choreography-derived runtime for Rust, detailing its model, protocol language, endpoint operations, transport, and verification. It emphasizes exact, finite-session guarantees, how projections shape role programs, and how transports and resolvers enforce protocol fidelity. While framed as a debugging-oriented topic in the title, the content serves as a deep architectural reference for implementing and debugging complex distributed protocol runtimes in Rust.
