Build-2 matrix (OnePlus 15/A16 + Lenovo TB330FU/A15) delivered the big
answer: traceroute.udp4 reads real hops via pure-Kotlin MSG_ERRQUEUE on
BOTH devices — the C-over-JNI shim is dead for Android 15+. Per-network
ICMP works as designed (phone ping6: cellular-only with topology
evidence). mDNS meta-query confirmed broken on both devices while
concrete types find real services — production must enumerate types.
Network finding: hudeWLAN RAs advertise a v6 default route but no global
prefix — the LAN's IPv6 is half-broken (nice dogfood case).
Tablet Shizuku bound 0/7 (binder alive, permission granted): first-spawn
dex extraction on slow storage suspected — bind window now 25s + one
retry. versionCode 3.

multinetwork now SUPPORTED (wifi+cellular bound concurrently; the cellular
request surfaced a second dual-stack PDN), Shizuku battery 7/7 in 2.9s
(was 4/7 in 34s), rtt_ms locale-clean. Remaining probe improvements
(per-network ping6, longer mDNS/ip-monitor windows) noted in build-status.

- AndroidManifest: add CHANGE_NETWORK_STATE — requestNetwork threw
SecurityException, multinetwork.request_and_bind could never run.
- IcmpProbe: format rtt_ms with Locale.ROOT — Austrian locale produced
"38,1" in the JSON report.
- ShizukuRunner/ShizukuProbe: bind the UserService once per battery
(execBatch) instead of per command; the per-command bind/unbind raced
Shizuku and 3/7 commands died on SHIZUKU_BIND_TIMEOUT.
Archive the report at echolot-prober/reports/, record findings in
build-status.md. Notable: errqueue path fully reachable on Android 16 —
the native shim may be unnecessary on modern devices.
