- IcmpProbe: attempt the echo on the default network AND each active
network (Network.bindSocket + per-network DNS). Run 1's ping6 EAGAIN was
topology (v6 only on cellular), not capability — now the report shows
which networks carry which family instead of a bare ERROR.
- New traceroute.udp4 (TracerouteProbe): actual UDP traceroute reading
ICMP time-exceeded via Os.recvmsg(MSG_ERRQUEUE) with cmsg parsing —
reflection per repo convention (API surface exists ~34+). If this
returns hops, the C-over-JNI shim is unnecessary on that device.
sock_extended_err layout constants documented in OsAbi.
- MulticastProbe: 10 s window; meta-query PLUS concrete types
(_http._tcp, _googlecast._tcp) — run 1 showed the meta-query alone
returning 0 on a network with live services; capture names + failure
codes as evidence.
- ShizukuProbe: ip monitor window 2s -> 5s, gateway ping in background to
provoke a NEIGH transition instead of hoping for ambient churn.
