Origin validation is a separate decision from best path
This post is part of Protocol in Code, a free series that reads network protocols as logic — inputs, state, and branches — rather than as configuration examples. The full source, walkthroughs, and site lessons live in the repo: pathvector-studio/protocol-in-code. If you're newer to this and want to build the protocols hands-on before dissecting them, start with the companion Protocol Lab series instead.
