A row read "22 kB · full" directly beneath "uploaded to fmr", while the status
line above said the upload went as BALANCED. Both were true and they described
different documents: the row showed ArchivedRun.anonymization, which describes
the *archived* copy - deliberately unredacted, so always "full" - and the status
line described the *uploaded* copy.
Read together, that says the complete data was uploaded when a redacted copy was
sent. A privacy display that overstates what left the device is worse than none,
and telling the user what left the device is the one thing this screen is for.
The level a run was uploaded at is now recorded separately (uploaded_as) and the
row says "kept complete on this device" / "uploaded to fmr as balanced" - each
label naming the copy it belongs to.
Two more from the same screenshot:
- Every row showed no verdict. The archive read summary.verdict; the schema
calls it summary.overall. Silently null on every run, so the list's most
prominent element was blank while everything else looked fine. The test
fixture had the same wrong field name, which is why it passed.
- The status line rendered the server's raw JSON index entry into the UI.
Verified on device: a fresh run archives with verdict "yellow" and
uploaded_as "balanced" beside anonymization "full".

On-device verification found both.
safeDrawingPadding() was on the run screen but not on Settings or History -
they were added later and never got it - so "< Back Settings" sat under the
status-bar clock. The same fault the run screen had already fixed, reintroduced
by new code that did not know about it.
Settings also read "0 run(s), 23 kB stored": the count came from
UiState.history, which stays empty until the History screen has been opened,
while the size read the archive directly. Two sources for one fact; the count
now reads the archive too.
Verified on a OnePlus 15 (A16): header clears the status bar, count reads
"1 run(s), 23 kB stored".

POST /admin/enroll-tokens now returns the whole link, not just the token:
echolot://enroll?v=1&u=<control URL>&p=pin-sha256:<b64>&t=<token>
The server is the only party that knows all three parts at once, and the part
an operator gets wrong by hand is the base64 pin — which does not fail loudly,
it just never matches, surfacing days later as an inscrutable TLS error. The
app takes the link from a paste or from an echolot:// deep link (QR scan), and
writes URL, pin and credential together or not at all.
One trap the tests pin: an unencoded "+" in a query string decodes to a space,
so a hand-assembled link arrives with a pin wrong by one character. Base64 has
no spaces, so they are restored — unambiguous, and it cannot damage a correctly
encoded pin.
Also fixes a spec divergence: §2.1 names the field device_credential and the
first implementation shipped "credential". Both are sent now and the client
prefers the spec's; the alias goes once nothing reads it.

Both sides now declare what they will talk to, and enforce it. Two axes kept
deliberately separate, because conflating them is the trap:
protocol_version — CAN these builds talk. The correctness axis. Below 1.0.0
the minor is the breaking axis, per SemVer §4.
release window — MAY they, per policy. [min, max), advertised in the
profile, overridable by the operator.
The server refuses out-of-window apps with 426 and a body naming both versions
and the accepted range; the app checks the profile in both directions before a
run rather than discovering mid-measurement that it will be refused.
Three rules that shape the rest:
- GET /v1/profile is never gated. It is where a refused client learns which
version it needs; gating it leaves the user with a network error instead of
an answer, which is precisely the confusion this exists to remove.
- An unparseable or absent version is "unknown", and is allowed. Development
builds report "dev", and a client too old to send the header cannot be
identified anyway.
- Bounds sit at breaking boundaries, not at releases, so shipping a patch
never requires editing a range. The app's server minimum is 0.4.2 for a
stated reason: earlier multi-homed servers mis-addressed granted sends and
the client measured 100% downstream loss that never happened.
The app's versionCode is now derived from its SemVer instead of being a second
number someone has to remember to bump.

fmr binds two IPv4 addresses. connFor picked whichever socket of the right
family came first in the bind list, so a downtrain for a session established on
.150 went out from .151 — and every packet was dropped by the client's NAT,
which has no mapping for that pair. tcpdump on the server showed all 50 leaving;
the client saw none. Read as "100% downstream loss", which is the worst kind of
wrong: a confident measurement of something that never happened.
Sessions now record which of our own bound addresses received their traffic, and
granted sends (and delayed echo) go back out through that socket. The fallback
to a family match is kept for the case where nothing has been received yet, and
the test pins both paths — a single-homed lab can never reproduce this.
Also: the client-side halves of the same work — anonymizer (core-privacy), local
run archive with retention (core-archive), upload client, and the app's settings
and history screens.

Verified against Shizuku 13.6's manifest (pulled APK, aapt2 xmltree): its
wireless-debugging entry points (AdbPairingTutorialActivity,
AdbPairingService, StarterActivity) have no intent filters, so they are
not exported and cannot be launched externally; MainActivity answers only
MAIN/LAUNCHER with no deep link. Starting wireless debugging from another
app is therefore not possible, which is why the handoff lands on the
root-start screen.
Instead the hint now names the exact steps inside Shizuku ("Pairing", then
"Start"), and a second tap opens Developer options — that action IS public
and exported, and Wireless debugging has to be on before Shizuku's
wireless start works.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A third-party app cannot start Shizuku — the wireless-debugging pairing
flow is privileged and lives in Shizuku's own app — so the banner
deep-links there when it is installed but stopped, and fires the
permission request directly when it is running but unauthorised. The hint
line says which.
Verified on-device together with the earlier UX work: progress bar showing
"test 4 of 8 · icmp.ping6 · ~33s left", Cancel beside the disabled Run
button, cutout-safe title, and the banner live-updating from
not-running to needs-permission via the binder listener.

Distinguishes not-installed (say nothing — don't nag users who don't use
Shizuku) from installed-but-stopped (amber banner: start it to include
shell-tier tests), plus running-unauthorised and ready. Detection is
listener-based since pingBinder() only becomes truthful once
ShizukuProvider delivers the binder; a launch-time poll would show a false
"not running". Installed-vs-not needs the <queries> entry on Android 11+.
Verified on-device: with shizuku_server stopped, the banner shows before
pressing Run; the title also now clears the status bar/cutout after the
safeDrawingPadding fix.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
- 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.

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.

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.

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).

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.
