nx_iot_announce_test.nx

nx_iot_announce_test.nx -- in-memory smoke for nx_iot_announce. Exercises the parts that need no real sockets: - classifier first-byte signature matrix - discovery payload builders (Magic Home + WiZ) - sealed-enum validity gates - sockaddr port + IP decoders Real-network verification (binding sockets, broadcasting, recvfrom-with-timeout) is documented in the roadmap and runs only once user has the hub box on the LAN. This smoke is environment- independent so it compiles + passes inside any container or qemu run. expect_exit: 0 license_tier: ORIGINAL
