The sample is not published in the store. The 11-archive manifest audit found only ProtonDB Badges API v2 in that set. Storage Cleaner 1.4.0 showed an empty-data panel and four disabled cleanup buttons in local Chromium with a stub backend; no cleanup action was tested.

+# LocalSend ARM64 build and isolated Frame probe
+
+The official Decky Localsend archive remains **broken/blocked**: its helper is
+x86_64. A source rebuild is now proven to execute on the ARM64 Frame and answer
+the LocalSend 2.0 info endpoint. This is a core runtime result, not a working
+official-plugin or file-transfer claim. [Machine-readable evidence](framey-localsend-arm64-2026-10-26.json)
+records the exact scope and cleanup.
+
+## Reproduce the build
+
+The helper is MIT-licensed; the separate official Python plugin is BSD-3-Clause.
+Use the pinned helper source and retain its license for any redistribution.
+No binary is redistributed in Frame Control, and no installer digest or
+architecture safeguard was changed.
+
+```sh
+framey_build_dir=$(mktemp -d)
+git clone https://github.com/MoYoez/LocalSend-Go "$framey_build_dir/source"
+git -C "$framey_build_dir/source" checkout --detach 66edc509a28b9f877e7374504892dcbc653a4da4
+cd "$framey_build_dir/source"
+env GOTOOLCHAIN=go1.25.7 CGO_ENABLED=0 GOOS=linux GOARCH=arm64 \
+  go build -trimpath -o "$framey_build_dir/localsend-core" .
+sha256sum "$framey_build_dir/localsend-core"
+```
+
+Two builds produced the same static aarch64 ELF SHA-256:
+`e79238f6051ce34f172f765ae918d3d902b819e27377989a55e5b1eba10e46f9`.
+The official ELF uses Go 1.25.7 too, but embeds no VCS revision, so the exact
+source correspondence is still unproven. The rebuilt helper recognizes every
+CLI flag supplied by the official Python backend.
+
+## Real Frame scope
+
+Tests ran under the normal atomic `/tmp/frame-test.lock` with a private temporary
+directory. `-h` exited before configuration or networking. For the health probe,
+`unshare -Urn` created a private user/network namespace with loopback and a veth
+pair entirely inside it: no external interface or default route. The veth used
+the documentation-only `192.0.2.1/24` address. Upstream rejects a loopback-only
+discovery interface, which is why the second isolated attempt used a veth.
+
+The helper used a private config/upload path, `-skipNotify`,
+`-useAutoSave=false`, `-useAutoSaveFromFavorites=false`, `-useHttp=true`,
+`-useReferNetworkInterface probe0` and `-scanTimeout 1`. The test client sent only
+`GET /api/localsend/v2/info` over loopback; it returned version `2.0`, device type
+`headless` and the private test alias. No upload, transfer, pairing or external
+discovery request ran. The helper exited; its private config/log and executable
+directory were removed; no service or power setting changed. The lock was
+released. An independent cleanup reacquisition found another job's lock and
+left it alone; cleanup success comes from the original probe's process wait and
+temporary-directory exit, not that deferred audit.
+
+Before enabling an ARM64 official package, verify the unmodified Python backend
+and frontend/proxy protocol with this source revision, then HTTPS, discovery and
+an explicitly safe private transfer. The official store must publish a matching
+ARM64 archive or Frame Control must gain a separately reviewed, digest-scoped
+build/package path. Compiling the core does not justify accepting the current
+x86 archive or marking the full plugin works.

+# v0.4.37 release smoke on a real Frame
+
+On 26 October 2026 at 00:27 UTC, a physical Linux host ran the release
+`scripts/frame-smoke.sh` against a real Steam Frame. The smoke scripts were
+byte-identical to tag `v0.4.37` (`5239dae1a82c35635ef89f59eac9721c5014e2ed`).
+The headset reported Frame OS 0.5.6, build `20261022.6153909`.
+
+The test acquired `/tmp/frame-test.lock` with a unique owner marker before
+reading the headset. SteamVR activity stayed at 3 (standby); initial proximity
+raw was 6.3125 and battery was 99%. The test released only its own lock after
+cleanup. Battery read 100% afterward.
+
+All **13 of 13** smoke steps passed. ARM64 and Windows test titles installed,
+launched, and were removed. The x86_64 title installed and was removed; its
+launch reported that Steam Linux Runtime 4.0 was found but not installed, so
+this result does **not** establish x86_64 game execution. Devkit properties and
+status reads passed. No key was paired. The final cleanup removed the reserved
+test titles and processes. The private result remains under
+`/tmp/frame-v0437-smoke-results/`; this summary omits headset identifiers and
+device status details.
+
+Because the headset was in standby, this test did not verify wearer-visible
+pixels, physical controller input, a Framey panel, or official Decky plugin
+settings in VR. Those checks remain on the [worn checklist](../framey-vr-check.md).
