Four things a user could not do, one that has been broken since dev.126, and the review round on all of it. None of the three features is verifiable on this bench, so they ship to be tested: nobody here has a Windows machine or a ColorLight card.

Windows can report

httpsPost gains a WinHTTP branch. libcurl has no dev package on the Windows runner and no public binary cache, so acquiring it would mean building curl from source on every release; winhttp.lib is in the SDK and costs one link entry. Schannel and the Windows certificate store come with it, which is the same "use the OS's own TLS" rule every other platform follows.

Same contract as the libcurl path: HTTPS only, redirects disabled, body discarded, true only on 2xx, one timeout across every phase.

Linux and macOS read the ethernet link

ethLinkUp() was hardcoded false on every non-Windows desktop, so PanelCardDriver reported "no ethernet link" while driving a card perfectly. The send path was implemented (AF_PACKET on Linux, BPF on macOS); only the link-state query was missing, so the driver's health check contradicted its own output.

Linux reads /sys/class/net/<if>/operstate, macOS uses SIOCGIFMEDIA with IFM_ACTIVE, both describing the NIC the sender bound to. Reported by a user driving a ColorLight card from a NanoPi.

A send update button on the Stats card

The automatic trigger is a version comparison, which says nothing about a setup that changed without one: someone who reported a bare board and then wired up the fixtures they actually run. The button re-sends on demand, overwriting their row rather than adding one, and carries its own refresh event so the install count stays a count of installs.

Every press says what happened: sent, no consent, no network, AP mode, or server unreachable. Verified end to end against the deployed worker.

Scripted modules name the script they run

effect:MoonLive/aurora.mle instead of the uninformative effect:MoonLive. Only scripts we ship are named: a name a user invented is text they typed, so it is counted under its module type and never sent. The allowlist comes from the generated script_catalog.h, so there is no second list to drift.

The container was dead on arrival

The published image died at startup on libcurl.so.4: cannot open shared object file, on both architectures, ever since the Linux binaries gained that link. The distroless base carries four libraries and libcurl's chain runs much deeper, so the fetch stage installs it and an ldd sweep collects what the loader actually resolves. The four the base already provides are excluded rather than copied over: base and fetch stage are pinned independently, and shipping both would put two glibc builds in one image.

CI could not catch this: the publish job builds the image but never runs it. Verified by building and running on a NanoPi.

Docs

The Linux tutorial now covers both routes: package and Docker, what each costs, how each survives a reboot, and the overlay-on-overlay failure that stops Docker on a board whose root is already an overlay. Plus where else this runs: a Pi, a NAS, a mini PC, a router.

Reviews

Seventeen findings across two reviewers. Ten fixed, seven declined with reasons in the commit body. The two worth naming:

  • A failed button press consumed the automatic report. Pressing it before the install report had gone out, and having the send fail, marked the version reported anyway: the install was then never counted, and the user had been told the press failed. Invisible to all 1,942 existing tests.
  • A refresh carried previousVersion, and the server reads that field's presence as what makes a row an upgrade. Every refresh would have reported as an upgrade from the version already running.

CodeQL failed on its upload step during a GitHub API outage and passed on a re-run of the identical commit. No code change.

Verification

Spec drift, prose, strict docs, taglines, platform boundary, hot path, device catalog, firmware list, desktop build, 1,943 unit cases, 24 scenarios, 158 JS tests, the no-backend build, and the GCC build that caught an ifm_name truncation clang accepted.

Not verified here, and that is the point of merging: Windows reporting, and the ethernet status line against a real card.

A scripted module reported as `effect:MoonLive` whatever it was running, which is the least interesting fact about it. Entries now carry the script: `effect:MoonLive/aurora.mle`. Only scripts we ship are named, because a script name a user invented is text they typed, and the report never carries that.

Core:
- isFactoryScript() in MoonLiveScriptFile.h, beside isScriptExt for the same reason: the generated script_catalog.h is the only list of shipped names, so a second copy would drift the day a script is added. It matches per role, so a name is checked against its own catalog rather than all five.
- factoryScriptOf() reads a module's `script` control and returns the name only when the catalog has it; anything else degrades to the bare type name.

UI:
- The stats nudge links to "Why you might like this" on the MoonCloud page, so the reasons live in one place rather than growing the nudge.

Tests:
- Three cases: a shipped name is reported, a user-authored name is counted but never named, and a catalog name under the wrong extension is not a match. Control-checked by bypassing the allowlist, which fails the user-script case on exactly the two assertions that matter.

Docs/CI:
- mooncloud.md: the Stats section renamed to "Why you might like this" and reframed to lead with what the reader gets. Sync stays.
- system.md: the payload sentence says script names are reported only for shipped scripts.

Three things a user could not do, and one that has been broken since dev.126.
None of the three is verifiable here, so they ship to be tested: nobody on this
bench has a Windows machine or a ColorLight card.

**Core**
- Windows sends its MoonCloud report through WinHTTP. libcurl has no dev package on the runner image and no public binary cache, so acquiring it would mean building curl from source on every release; winhttp.lib is in the SDK and costs one link entry. Same contract as the libcurl path: HTTPS only, no redirects, body discarded, true on 2xx, one timeout across every phase
- A `send update` button on the Stats card re-sends the report on demand, for a setup that changed without a version change. It overwrites the row rather than adding one, and carries its own `refresh` event so the install count stays a count of installs. Every press now says what happened: sent, no consent, no network, AP mode, or server unreachable
- Scripted modules report which shipped script they run (`effect:MoonLive/aurora.mle`); a name a user invented is counted but never sent

**Light domain**
- `ethLinkUp()` was hardcoded false on every non-Windows desktop, so PanelCardDriver reported "no ethernet link" while driving a card perfectly: the send path was implemented (AF_PACKET, BPF) and only the link-state query was missing. Linux reads sysfs operstate, macOS uses SIOCGIFMEDIA, both describing the NIC the sender bound to. Reported by a user driving a ColorLight card from a NanoPi

**Docs/CI**
- The published container image died at startup on `libcurl.so.4: cannot open shared object file`, on both architectures, since the binaries gained that link. The distroless base carries four libraries and libcurl's chain is 28 deep, so the fetch stage installs it and an ldd sweep collects what the loader actually resolves. Both Dockerfiles, since the workflow keeps its own copy. Verified by building and running on a NanoPi
- The Linux tutorial covers both routes: the package and Docker, what each costs, how each survives a reboot, and the overlay-on-overlay failure that stops Docker on a board whose root is already an overlay. Where else this runs: a Pi, a NAS, a mini PC, a router
- MoonCloud's worker accepts the `refresh` event (deployed, version 3009bee2)

Verified: spec drift, prose, strict docs, taglines, platform boundary, hot path,
device catalog, firmware list, desktop build, 1942 unit cases, 24 scenarios,
158 JS tests, the no-backend build, and the GCC build that caught an ifm_name
truncation clang accepted. ESP32 freshness skipped: stale from a file this
branch does not touch. Improv skipped: no board on USB.

In `@src/core/MoonStatsModule.h`:
- Line 421: Update the report construction around buildMoonStatsReport() so
previousVersion() is passed only when the event kind is upgrade; pass no
predecessor for Refresh while preserving the existing event kind and other

- Around line 273-284: The manual report path in
MoonStatsModule::onControlChanged must not call blocking sendReport or
platform::httpsPost on the render or scheduler thread. Dispatch the request
through a worker task or non-blocking HTTPS state machine, then update the
success or failure status only when the request completes; preserve the existing
AP-mode guard and messages.

In `@src/platform/desktop/platform_desktop.cpp`:
- Around line 589-590: Update the WinHTTP request flow around WinHttpSetTimeouts
so timeoutMs enforces a single deadline for the complete request, not
independent resolve, connect, send, and receive periods. Use asynchronous
request handling with deadline cancellation, or close the request handle when a
timer reaches the deadline, while preserving the existing timeout behavior for
requests completed before expiration.
- Around line 1672-1678: Update ethLinkUp() to determine physical carrier status
instead of reading operstate. Read the interface’s carrier value from
/sys/class/net/<interface>/carrier or use IFF_LOWER_UP, and return true only
when the carrier state is 1; leave IP-connectivity handling in ethConnected()
unchanged.
- Around line 1721-1724: Update ethLinkSpeedMbps so ethTestLinkSpeed_ is used
only when ethRawIfName_ indicates unbound capture mode; when a real interface is
bound but posixAdapterLink leaves m at zero, return zero instead of the default
test speed.
- Around line 1717-1719: Update ethConnected() separately from ethLinkUp() so it
reports true only when the bound interface has an assigned IP address and DHCP
is complete, while ethLinkUp() continues to report carrier state only. Preserve
NetworkModule’s ability to distinguish carrier detection from the ConnectedEth
state.

In `@test/js/mooncloud-report.test.mjs`:
- Around line 63-69: Strengthen the test around the event predicate by asserting
the actual comparisons against “install”, “upgrade”, and “refresh” rather than
searching the source text for those words, or invoke handleReport with a refresh
payload and verify its behavior. Keep the unknown-event discard assertion
intact.

Move the manual report off the render loop

The send update button invokes MoonStatsModule::onControlChanged() directly. That callback calls sendReport(), which calls MoonCloudModule::post() and then the blocking platform::httpsPost(..., 4000). The platform contract requires HTTPS callers to run off the render path. A slow or unreachable server can therefore block the inline render loop for up to the configured timeout before the status is updated. Moving the call to tick1s() alone does not fix this because the scheduler also runs tick1s() inline. Use a worker task or a non-blocking HTTPS state machine, and update the status when the request completes.

Do not send an upgrade predecessor for Refresh.

markReported() copies runningVersion_ to reportedVersion_, so previousVersion() returns the current version after an upgrade report. buildMoonStatsReport() serializes that value whenever it is non-empty, regardless of event kind. The worker then overwrites reports.previousVersion and appends the same value to events. A later refresh can therefore replace the real predecessor and add a self-version to previous-version statistics. The event remains refresh; it is not relabeled as upgrade.

Pass previousVersion() only for upgrade events.

Enforce one timeout for the complete WinHTTP request.

WinHttpSetTimeouts(session, t, t, t, t) sets separate resolve, connect, send, and receive timeouts. It does not enforce one total timeoutMs deadline. A slow request can therefore consume several timeout periods, and connection attempts to multiple addresses can extend it further. This differs from the libcurl path, where CURLOPT_TIMEOUT_MS limits the complete request. (learn.microsoft.com)

Use an asynchronous request with deadline cancellation, or close the request handle from a timer when the complete deadline expires.

Use the Linux carrier state for ethLinkUp().

operstate is an operational-state value. It can remain dormant or unknown while the driver reports physical carrier. The API requires ethLinkUp() to report the physical link independently of IP or higher-layer readiness.

Read /sys/class/net/<interface>/carrier, or query IFF_LOWER_UP, and treat carrier value 1 as link up. The Linux kernel documents IFF_LOWER_UP as the driver-reported carrier state. (cdn.kernel.org)

As per path instructions, “Ethernet status APIs should distinguish physical link (ethLinkUp) from IP connectivity (ethConnected).”

Implement IP connectivity separately from carrier detection.

platform.h defines ethConnected() as “IP assigned (DHCP complete)”. POSIX ethConnected() calls ethLinkUp(), which only checks the bound interface’s carrier state. In NetworkModule, this can promote a carrier-only interface to ConnectedEth before it has an IP address. Add a separate IP-assignment check for ethConnected().

Return zero when the bound interface has no available speed.

If the bound interface is down or does not report a speed, posixAdapterLink() leaves m at zero. Line 1724 then returns the default test value of 1000 Mbps. Production callers consequently receive a fabricated negotiated speed.

Keep ethTestLinkSpeed_ only for unbound capture mode. Return zero when ethRawIfName_ identifies a real interface but its speed is unavailable.

Proposed fix
 uint16_t ethLinkSpeedMbps() MM_NONBLOCKING {
+    if (!ethRawIfName_[0]) return ethTestLinkSpeed_;
     uint16_t m = 0;
-    if (posixAdapterLink(m) && m) return m;
-    return ethTestLinkSpeed_;   // unbound, or a speed the OS would not state
+    if (posixAdapterLink(m)) return m;
+    return 0;
 }

As per path instructions, Ethernet status APIs must “report negotiated speed as 0 when unavailable.”

Assert the refresh predicate itself.

accepted includes comments. If the condition stops comparing report.event with "refresh" but the comments remain, these assertions still pass. Match the three comparisons directly, or exercise handleReport with a refresh payload.

Seventeen findings across two reviewers on the work in 6695ac7. Ten fixed, one
skipped as unreachable, six accepted or declined with a reason below.

**Core**
- A refresh carried `previousVersion`, and the server reads that field's PRESENCE as what makes a row an upgrade. Its value is `reportedVersion`, non-empty whenever the button is pressed, so every refresh would have reported as an upgrade from the version already running. Passed only on Upgrade now, with a test (🐇)
- A failed button press called `markReported()` anyway. Pressing it before the automatic report had gone out, and having the send fail, set `reportedVersion` to the running version: `reportDue()` was then false forever and the install was never counted, silently consuming the report the user had just been told failed. The automatic path still marks either way, because nobody is waiting for it (👾)

**Light domain**
- `ethLinkSpeedMbps` returned the test-override speed for a BOUND adapter that states no rate. It reports 0 there now: admitting no speed is known beats inventing one for a real NIC (🐇)
- The `IFM_SUBTYPE` table and the sysfs read existed twice, once for link state and once for the interface labels. One `posixIfLink` helper answers both (👾)

**UI**
- The event pie read "Install or upgrade" while showing refresh events too (🐇)
- A half-finished comment from the `refresh` to `send update` rename (👾)

**Docs/CI**
- The `ldd` sweep copied libc, libstdc++, libm and libgcc_s over the distroless base's own. Base and fetch stage are pinned independently, so that put two glibc builds in one image and let the loader pick by path order. Excluded now, rebuilt and run on the bench NanoPi (👾)
- `echo ... | tee /etc/docker/daemon.json` discarded existing Docker settings, which a NAS or board image often ships. It merges the key now (🐇)
- `mooncloud.md` and `system.md` described reporting as install-or-upgrade only, and `system.md` omitted the `send update` control entirely (🐇, 👾)
- Two unverified numbers removed: "28 libraries deep" came from one `ldd` run on one arch, and the image size predated libcurl being linked (👾)

**Declined, each with its reason**
- `ethConnected` should mean "IP assigned": it already does on ESP32, where NetworkModule's DHCP states run. Desktop has no DHCP state machine and `WaitingEth` never executes there, so the split would add a distinction nothing consumes (🐇)
- The button's send should be asynchronous: `MoonTalkModule::send()` already posts synchronously from the same `onControlChanged` path, which is not marked `MM_NONBLOCKING`. Changing one of two identical call sites would leave two patterns for one job (🐇)
- `operstate` should be `carrier`: unverified. The bench board went off the network mid-check, and `operstate` reports `up` only with a carrier. Not changing a hardware-facing path on an unverified claim (🐇)
- The JS worker test string-slices the source rather than exercising it: true, and the existing convention in that file. Rewriting the harness is its own change (🐇)
- `ethRawIfName_` is not cleared on the Windows bind path: unreachable, since Windows compiles a different `ethLinkUp`. Rated latent by the reviewer (👾)
- `WINHTTP_OPTION_DISABLE_FEATURE` may be the older API: marked PLAUSIBLE and unverifiable without the SDK. Windows is untested anyway, which is what shipping it will reveal (👾)

CodeQL failed on the upload step while GitHub's API was degraded, and passed on
a re-run of the identical commit. No code change, so nothing to fix.

Verified: clang and GCC builds, 1943 unit cases, 158 JS tests, prose, specs,
strict docs, and the container rebuilt and running on the NanoPi.

The refresh test asserted that `buildMoonStatsReport` would drop a
previousVersion it had been handed explicitly. It is a pure function over its
arguments and rightly emits what it is given: the guard lives one layer up, in
`sendReport`, which passes the predecessor only on an upgrade. Three sanitizer
lanes caught it; a local run did not, because that run used a test binary built
before the case existed.

**Tests**
- The refresh case supplies no predecessor and pins what this layer does promise: a refresh carries no previousVersion, and an upgrade carries one. The comment names where the real guard is, so the next reader does not repeat the mistake

**Docs/CI**
- Delete the arm64 packaging plan. Its work shipped in a229be6 and was verified on the bench NanoPi: installed, ran, and reported to MoonStats as `linux-arm64`
- Backlog what that verification could not cover. The release builds arm64 on `ubuntu-22.04-arm` deliberately, for glibc 2.35, because Raspberry Pi OS bookworm ships 2.36 and a 24.04 build would install there and die at startup. Bookworm is the one target nobody has run it on, and `Depends: libcurl4 | libcurl4t64` has had only its trixie half exercised. A user with a Pi settles both in one command, so it closes on a report rather than a code change

Verified: 1944 unit cases pass, and the named case passes on its own.
