A minimal CoAP (RFC 7252) server built on coap-lite for message encoding and a tokio UdpSocket for transport. The socket, read loop and routing are kept in src/main.rs rather than behind a framework. Routes: GET /hello[?name=X] -> 2.05 "Hello, X!" (defaults to World) POST /hello -> 2.01, name from a raw text or JSON body GET /health -> 2.05 status + uptime Unknown paths return 4.04, known paths with the wrong method 4.05. Includes a CLI client (src/bin/client.rs) for smoke tests and unit tests covering the greeting, payload parsing and query decoding. Verified against node-coap as an independent implementation to confirm wire compatibility. The earlier Node.js prototype is kept under nodejs/ for reference.
