IPv6: absence is no longer a defect. If the network never provisioned v6
(no global address, no ::/0 route) the finding is ipv6.not_offered at INFO
(green) — most networks are still IPv4-only. If v6 IS advertised but
doesn't work, it's ipv6.broken at MEDIUM (yellow), because half-working v6
stalls connections. Verified on-device: our LAN advertises a v6 default
route with no path, and now reports ipv6.broken.
Autorun: `am start ... --ez autorun true` runs the suite immediately,
POSTs the report to the collection endpoint, shows the result for 3s and
finishes the activity (stays open if the upload failed). receiver.py gains
POST /report + GET /reports + GET /report/<name>. Verified end to end: one
adb command, report retrieved over HTTP, app closed itself.

A test device that can only reach fmr on 443 (LAN blocks other outbound
ports) can pull an APK via its own downloader — more resilient than adb's
sustained transport over flaky wifi. GET /apk serves APK_PATH. (Doesn't
help the Lenovo tablet, which ships no curl; kept for devices that do.)

The connector tore down a working adb link whenever the beacon reported a
new port, reconnecting every loop and spamming the phone with "wireless
debugging connected" notifications (~every 8s). Existing connections
survive rotation, so now: if any device-state entry exists for the IP,
leave it; only (dis)connect when there's no working link at all.

connect.sh polls the fmr beacon map and keeps `adb connect` current for
every device, now handling offline/stale entries and port changes
(disconnect+reconnect). Verified end to end: after Shizuku start + a
wireless-debugging toggle, the tablet's port rotated 38309->46667, the
beacon caught it, the connector reconnected, and Shizuku kept running as
an independent shell(2000) process.

Debugging against a real restricted LAN surfaced three fixes:
- Android blocks app cleartext HTTP by default (targetSdk 36) — the port
discovery + reachability were fine (phone curl reached fmr), only the
app POST was denied. Added usesCleartextTraffic for this dev tool.
- Multi-device: report + receiver are keyed by device (Build.MODEL) so a
phone and tablet don't clobber each other; connector connects each.
- POST over a VALIDATED internet network (prefer cellular) since the
wireless-debug wifi is often a restricted LAN.
- Status/notification now show the target beacon URL + which network, per
the request to surface what it's connecting to.
Verified live: beacon tracks the (frequently rotating) port via mDNS and
self-reports the current endpoint within seconds.

The phone's wireless-debug port rotates and the bridge drops; this makes
adb reconnect automatically. Three pieces:
- adb-beacon (Android dev app): reads adbd's own mDNS advertisement
(_adb-tls-connect._tcp) via NsdManager for the live connect port — no
root, no Shizuku — plus the wlan0 IPv4, and POSTs {ip,port} to fmr every
time it changes (continuous NSD discovery catches rotation in seconds).
Foreground service (specialUse) so it survives backgrounding.
- tools/adb-beacon/receiver.py: ~30-line rendezvous on fmr:9099 (secret-
gated POST stores the latest endpoint; GET returns it). Deployed as
echolot-adb-beacon.service.
- PC connector polls the endpoint and keeps `adb connect` current.
Dev tooling, separate from the product. Bootstrap: sideload the beacon
APK once (no adb needed); thereafter adb self-heals for everything.
