Pure-Kotlin parsers over the captures the battery already makes, tested
against the real archived dumps from both devices - including the
Lenovo's 1000000015 route tables (table ids stay strings), the OnePlus's
stray uid=2000 prefix and mid-line hoplimit, and an ip_monitor that only
ever said EXEC_TIMEOUT. ShizukuProbe now returns three tests; a failed
capture is SKIPPED with its reason so no test type silently vanishes.

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.

Multi-module Android app, built bottom-up from a verifiable core.
core-protocol is pure Kotlin/JVM (no Android SDK): SPKI-pinned control
plane (enroll/profile/session over HttpsURLConnection — API-1 compatible,
hostname verification off, trust is the pin), HKDF-SHA256 session keys,
ELT1 UDP data plane (HMAC gate, ECHO+observation, MTU probe) —
byte-compatible with the Go server.
Unit tests incl. the RFC 5869 HKDF vector (key derivation provably matches
the server). LiveServerTest + scripts/test-fmr.sh prove the client
end-to-end against the deployed fmr server: profile (8 caps), session,
ECHO rtt~11ms with the observation block returning our observed NAT port,
MTU 1400->1400, observations. Live test self-skips without ECHOLOT_LIVE_*.
Two client bugs caught live: java.net.http hostname verification (→
HttpsURLConnection, also the Android-minSdk-26 choice) and ECHO padding
needed for the observation to survive anti-amplification.
