The goal is not to build a production gateway, but to make the architecture and invariants explicit: how control planes and data planes interact, how routing decisions stay local, and how systems remain available when coordination layers fail.

I built this mainly to deeply understand how modern edge and ingress systems work under the hood, and to have a clean, self-contained reference that makes the patterns explicit.

Happy to answer questions about the design choices, failure modes, or how this compares to real-world systems.
