Mirrors NetworkMonitor: per active network, fetch the AOSP default
generate_204 endpoints and check for HTTP 204 No Content.
- HTTPS https://www.google.com/generate_204 == 204 -> validated internet
- HTTP http://connectivitycheck.gstatic.com/generate_204: 204 -> clean;
an unfollowed 3xx or a 200-with-body -> captive portal (Location captured)
- both fail -> no_internet
Per-network verdicts (bound via Network.openConnection), redirects not
followed (the 3xx IS the evidence). Findings: captive_portal (medium) and
no_internet (high). New test type net.captive_portal (net family ->
connectivity category). App gains usesCleartextTraffic (a network
diagnostic that intentionally probes plain HTTP).
Builds; measurement verdict tests still green. On-device verification
deferred with the rest (flaky test devices).

Ports the prober's validated Shizuku tier: AIDL UserService, the build-4
dual-path ShizukuRunner (UserService bind where it works, legacy
newProcess reflection fallback where it doesn't — exec_path records
which), and ShizukuProbe running the shell command battery, emitting a
shizuku-tier link.ip_monitor Test with per-device dumps as evidence.
Self-degrades to UNSUPPORTED without Shizuku.
Wired into RunViewModel (sets tiers.shizuku); app APK assembles. On-device
verification deferred — no device reachable at build time (flaky LAN
dropped the tablet, phone debugging off). Expect UserService on OnePlus,
newProcess on Lenovo per the prober.

First assembling build of the production app. Android toolchain mirrors
the prober (AGP 9 built-in Kotlin; applying kotlin.android too
double-registers the kotlin extension — the one gotcha).
core-probe (Android lib): Probe→core-measurement Test abstraction;
NetworkInventory (LinkProperties→networks[]), LinkSnapshotProbe,
per-network IcmpProbe (ported from the prober's validated logic).
app (Compose): RunViewModel orchestrates probes into a MeasurementDocument
with a §7.3 summary + first-pass findings; UI renders traffic lights,
networks, tests, findings; JSON export. Rotation-safe (ViewModel).
App-tier only; server-facing (core-engine) + Shizuku are additive
follow-ups. Debug APK 9.5 MB, assembles clean.
