- Probe.estimatedMs (measured per probe; timeout-bound ones dominate)
drives a determinate progress bar and "test N of M · ~Xs left",
including the Shizuku battery in the total.
- Cancel stops the run and shows the partial results as a normal document
(findings + verdict over what was collected) but never uploads them.
- safeDrawingPadding() on the root column: Android 15 is edge-to-edge by
default and the title was colliding with the status-bar clock and the
camera cutout.

The probe identified the LAN's IPv6 RA sender end to end from an
unprivileged app: EUI-64 MAC recovery (78:9A:18:54:B8:F9, matching the
Shizuku neighbor table) -> MikroTik by OUI, corroborated by the UPnP
device description (RouterOS/7.23.2, MikroTik Router) and reverse DNS
(router.hudelist.local). Cellular's RFC 7217 privacy RA source is
correctly reported as not-EUI-64 instead of guessed. The SSDP sweep also
inventoried a Synology DS1522+ and a Sky gateway — the raw material for
future LLDP/mDNS cross-matching.
Fixes found by running it: added the confirmed MikroTik OUI 78:9A:18 (+
other RouterBOARD ranges) and an elvis-operator bug that printed "no UPnP
response" alongside valid UPnP data.

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.

Hand-rolled RFC 5389/5780 STUN client (stdlib only) that exercises the
server's stun-5780 capability: one socket, three binding requests
(primary, OTHER-ADDRESS alternate IP, CHANGE-REQUEST port) — the
comparison classifies NAT mapping and filtering behavior.
Verified on the OnePlus: local 10.13.102.124 -> mapped
178.191.120.247:53259 (behind_nat true), alternate address answered from
the server's second IP, mapping endpoint-independent, filtering
address/port-dependent. Finding nat.symmetric (medium) for the
P2P-hostile case.
Two real bugs found by running it: port preservation was misread as "no
NAT" (compare addresses, not ports), and an unbound socket reports the
wildcard local address (resolve via a throwaway connected socket).

Resolves the server's canary zone through the platform resolver and
compares against the spec-frozen ground truth (probe-protocol §6.1):
reference records detect answers rewritten in flight, and a per-run nonce
name (uncacheable) proves the query reached the authoritative server.
Findings: dns.answer_rewritten (high), dns.authoritative_unreachable
(medium).
Verified on the OnePlus against the deployed fmr zone: 4/4 reference
records matched exactly, nonce name answered 192.0.2.21 with
reached_authoritative=true. First full client<->server measurement loop
on real hardware; report archived.

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).

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.
