traceroute.udp4 lands as TracerouteProbe: ICMP time-exceeded read off the
socket error queue via Os.recvmsg(MSG_ERRQUEUE) through the reflection
facade the prober validated on both devices - no root, no raw socket, and
the C-over-JNI shim stays dead. Emits the schema's TracerouteEvidence with
rtt_ns. OsAbi carries the hardcoded sockopt ABI numbers across, including
the measured fact that Os.getsockoptInt exists on neither device, so PMTU
must come from the errqueue, never getsockopt(IP_MTU).
local.mdns_inventory lands as MdnsInventoryProbe with both hardware-bought
lessons intact: the meta-query lies (0 results beside live services on both
devices), and 4s of listening misses what 10s catches.
App version 0.2.2.
