link.ra_source answers "who advertises IPv6 here, and which box is it": RA source per network, MAC recovered from the modified-EUI-64 link-local (privacy addresses reported as such, not guessed), vendor via a curated OUI table, UPnP/SSDP M-SEARCH for the gateway's server banner + device description (manufacturer/model/friendly name), and reverse DNS. All SSDP responders are recorded so a rogue RA sender that isn't the gateway can still be matched; the MAC accompanies every identity source as the hook for future LLDP/mDNS cross-matching. UI gains a "Router / IPv6 advertiser" panel. Icons: branding adaptive icon converted to vector drawables (+ PNG mipmaps, monochrome layer). The debug build is now a separate app — applicationIdSuffix .dev, label "Echolot DEV", DEV-badged icon — so it installs alongside a production build and can't be confused with it.

Echolot app
The production Android client (spec). Native Kotlin + Jetpack Compose. Multi-module; built bottom-up from a verifiable protocol spine.
Modules
| Module | Type | Status |
|---|---|---|
core-protocol |
pure Kotlin/JVM | done — client half of probe-protocol.md, verified live against the server |
core-measurement |
pure Kotlin/JVM | planned — measurement-schema.md types |
core-probe |
Android lib | planned — app-tier probes, ported from echolot-prober |
core-shizuku |
Android lib | planned — dual-path executor (UserService + newProcess fallback) |
app |
Android app | planned — Compose UI |
core-protocol is deliberately Android-free so it builds and unit-tests on any JDK (no Android
SDK) and can run integration tests against a live server.
core-protocol
Implements the control plane (SPKI-pinned enrollment/profile/sessions via HttpsURLConnection —
Android-API-1 compatible, hostname verification off because trust is the pin), the HKDF-SHA256
session-key schedule, and the binary ELT1 UDP data plane (HMAC gate, ECHO + observation block,
MTU probe) — byte-compatible with the Go server.
./gradlew :core-protocol:test # unit tests (crypto vectors, wire round-trip)
scripts/test-fmr.sh # live end-to-end test against the deployed server
test-fmr.sh mints an enrollment token over SSH, enrolls via the public control plane, computes
the SPKI pin from the served cert, and runs LiveServerTest — proving the client speaks the wire
protocol to the real server (enroll → profile → session → echo+observation → MTU → observations).
The live test self-skips when ECHOLOT_LIVE_* env vars are absent, so unit runs and CI stay green
offline.
