+# Emuchievements ARM64 hash helper feasibility, 26 October 2026
+
+The exact official Emuchievements 2.0.5 archive (store ID 28, SHA-256
+`98dcb443e81b9f9011cfe77c69eb659869c8e2df2df8b0a443df66cbfc2f5a89`)
+contains an x86_64 `Emuchievements/bin/hash`. Frame Control still blocks
+that archive on ARM64; this experiment did not install the plugin.
+
+The upstream source commit
+[`8567e94befffc943434b2adb842487274815f8bb`](https://github.com/EmuDeck/Emuchievements/commit/8567e94befffc943434b2adb842487274815f8bb)
+declares version 2.0.5. Its `src/py/main.py` matches the published ZIP's
+`Emuchievements/main.py` byte for byte (SHA-256
+`d4e72f136c94e48919575937ec4190f28864cc259eb111ef47f0df99f5912645`).
+The pinned build dependencies at that commit are libarchive
+`b3be94ba4f36943745e64a6a0a3c21c2d1281d3c`, libchdr
+`a20e04c12c0c20048bf771da6df7aa2e51f5e0cb`, and rcheevos
+`85a3209398e576d79170f569fcddf277640f3f06`.
+
+On a separate Linux host, the version-matched source and submodules built an
+x86_64 `hash` with CMake. It and the official x86_64 binary both returned
+`ff78ca6c21ac11504dbddbd5d4e7524a` for one synthetic `.rom` file. An
+isolated Debian cross-build using `gcc-aarch64-linux-gnu` and
+`g++-aarch64-linux-gnu` produced an AArch64 binary with SHA-256
+`9c7aedb80bdd64941aa5dd9b41f9bb8471411c812e04c7ee7d60486779d99997`.
+It links to `liblzma.so.5`, `libstdc++.so.6`, `libgcc_s.so.1`, and `libc.so.6`.
+
+A real Frame test acquired `/tmp/frame-test.lock` atomically with a unique
+owner before reading the device. SteamVR activity was **3** (standby),
+proximity raw **3.0625**, and battery **100%**. The ARM64 helper ran against
+the same synthetic ROM in a private `/tmp` directory, exited 0, and returned
+the same hash. The owned directory and lock were removed. No normal service,
+power setting, Steam library, real ROM, or installed plugin was changed.
+The separate host's source/build directory was also removed after the test.
+
+This proves only a single-file helper path. The official ZIP remains blocked
+because it still bundles x86_64 bytes. A release-ready port needs a packaged
+ARM64 helper with GPL-3.0 source and license compliance, format-specific hash
+coverage (including archives and CHD), a managed plugin transaction, actual
+Decky backend and frontend checks, and cleanup. RetroAchievements login,
+real ROM scanning, wearer-visible VR, and physical controller use remain
+unverified.

+# MusicControl / Music Control runtime checks, 26 October 2026
+
+Both official entries remain **partial**. Their pure-Python backends need a
+user-session MPRIS player and `dbus-send`, rather than Deck-specific hardware or
+an x86 binary. [Results](framey-mpris-runtime-2026-10-26.json) pin both archives
+and the actual Decky 3.3.0 executables used.
+
+Two runtime failures were reproduced and repaired:
+
+- The #335 `music-control-bound-methods` transformation was incorrect. Neither
+  manifest declares `api_version`, so Decky uses `module.Plugin` and explicitly
+  supplies the class as `self`. The earlier test used `module.Plugin()` and
+  therefore diagnosed a fixture error as an upstream bug. In actual Decky,
+  the transformation breaks discovery with `_get_dbus_env() missing ... self`
+  and transport with `_sp_player_dbus() missing ... parameters`. Managed installs
+  now retain the original class calls. This supersedes the earlier
+  [bound-method evidence](framey-music-control-bound-methods-2026-10-26.md).
+- On Frame OS 0.5.6, MusicControl 1.1.6's `/bin/sh` subprocess inherits Decky's
+  PyInstaller library path. Its bundled `libtinfo.so.6` needs `GLIBC_2.42`, which
+  the Frame's libc lacks. A private diagnostic backend confirmed the same
+  read-only D-Bus command fails with a shell and succeeds without one. Both
+  exact-archive backends now restore `LD_LIBRARY_PATH_ORIG` (or an empty path)
+  only in their copied D-Bus subprocess environment. The Decky process keeps
+  its original environment. The receipt records `music-control-system-dbus-env`.
+
+The patch is gated by store ID, SHA-256 and folder, and checks the expected
+source before editing. Existing installed copies need **remove/reinstall** or
+an explicit managed update; a desktop update alone does not rewrite them.
+The store still shows partial, with the same reason as the docs table.
+
+Actual Decky 3.3.0 amd64 ran each repaired production-managed install separately
+in a container with no network, host audio, host D-Bus, home or device access.
+A private `dbus-daemon` hosted a silent synthetic MPRIS service. Discovery,
+selection, identity, metadata, status, progress, volume/CanSeek reads,
+play/pause, next/previous, seek, track position and volume writes passed through
+the real legacy websocket RPC envelope. The service's own state independently
+confirmed each write. The shared plugin folder prevents co-installation; each
+entry was tested in a fresh container.
+
+Local headless Chromium loaded the shipped `headset.html` and exact official
+frontends inside their ordinary opaque `allow-scripts` iframe. The relay used
+actual Decky backends and allowed only the private fixture. Track/artist
+rendering, previous/next, play/pause, seek to 90 seconds, volume to 60%, Info
+navigation and close/reopen passed for both entries. Chromium retained its
+normal process isolation and sandboxed-origin restrictions. No external media
+or artwork request was permitted.
+
+Under the shared `/tmp/frame-test.lock`, a removable private Decky 3.3.0 ARM64
+user service loaded each corrected managed install on the real Frame.
+Read-only `sp_list_media_players` returned an empty string successfully for
+both, and `sp_get_media_player` returned their default Spotify bus name.
+These final checks used Decky's direct loopback websocket through SSH; they
+do not claim the deployed Framey HTTP/CEF route. Earlier CEF attempts encountered
+transient reinjection failures. No player controls ran on the real Frame.
+The private units, runtimes and owned Steam image-cache link were removed;
+independent follow-up reads confirmed cleanup and lock release. Battery was
+100 → 100. Existing managed Decky remained failed and the headset panel inactive,
+as found. Power settings were not changed.
+
+Remaining gaps: actual media-app playback/volume on ARM64, local-file album-art
+routing, physical controls and worn VR. Both backends truncate multiword player
+names to their last word. Music Control 1.1.7 automatically probes volume by
+writing 0.01 and restoring it; this was exercised only on the silent fixture.
+
+Validation: full Python suite **1,639 tests, 16 skipped**; focused managed-store
+suite **23/23**; shared frontend action checks; all **116** store digests unchanged.
+The complete fake-Frame audit passed: **61 installed/removed, 55 rejected**
+for documented safeguards; official backends are stubbed in that harness. The
+regression test uses Decky's actual legacy class convention for both entries,
+checks original/absent library-path restoration without changing the parent
+environment, and rejects transferring the patch to a different archive digest.
+
+The pinned HTTP/SSH flow also passed `scripts/e2e.sh test_framey`: **2/2**
+tests in 32.590 seconds. Its receipt assertion covers the replacement shim for
+both Music Control entries; the old assertion caused the first hosted e2e
+failure and left a plugin installed, cascading into the following test.
@@ -0,0 +1,15 @@
+# Superseded: Music Control bound-method fixture
+
+The #335 result was incorrect. Its test instantiated `module.Plugin()`, while
+actual Decky 3.3.0 uses the class `module.Plugin` for this legacy manifest and
+supplies the class as `self`. The published backend's explicit-self calls are
+correct in that runtime. Removing those arguments breaks actual Decky discovery

+The follow-up [real runtime checks](framey-mpris-runtime-2026-10-26.md) reproduce

+# Native plugin packaging blockers, 26 October 2026
+
+This is a static, digest-scoped follow-up. Neither plugin was installed or
+run on the Frame. Their compatibility statuses remain **broken**.
+
+## Decky Cloud Save 1.4.2, store ID 49
+
+The official ZIP SHA-256 is
+`b311d967ddf1b0f0046d36929645855891a40173e3a93f6f0cd8b1576b04b411`.
+It was downloaded and hash-checked without executing any member. Of its 27
+members, `decky-cloud-save/bin/rclone` is a regular executable of **60,776,600
+bytes** with ELF machine **62 (x86_64)**. The installer permits at most 30 MiB
+per member, so this exact ZIP fails before native architecture validation.
+Raising that limit alone would still leave an x86_64 executable on the ARM64
+Frame. No cloud credentials, saves, reads or writes were exercised.
+
+## Emuchievements 2.0.5, store ID 28
+
+The official ZIP SHA-256 is
+`98dcb443e81b9f9011cfe77c69eb659869c8e2df2df8b0a443df66cbfc2f5a89`.
+The [earlier helper check](framey-emuchievements-arm-2026-10-26.md) proved
+one synthetic ROM hash on ARM64, without installing the plugin. The upstream
+source commit `8567e94befffc943434b2adb842487274815f8bb` and its pinned
+libarchive, libchdr and rcheevos submodules were checked out separately for
+this audit. The source is GPL-3.0. An isolated Debian ARM64 cross-build made a
+2.6 MB helper (`c8794558a0d75294930f969a426e7d2ac13a27e3c1ff9bd8aae093e31596b9bd`),
+but it was **not shipped or run on ROM archives**. A complete source bundle
+without Git metadata compressed to about 8 MB; source and license distribution
+would be part of any release-ready port.
+
+The proposed source has an additional blocker. `backend/src/util.cpp` builds
+an extraction destination by appending each raw archive member pathname to
+an owned `/tmp/tmpdir.*` prefix, then passes it to libarchive's disk writer.
+It neither rejects `..`/absolute paths nor enables libarchive's secure path
+flags. `backend/src/main.cpp` later removes the extracted file's parent path.
+With an untrusted archive, those paths may leave the intended temporary
+directory. The plugin's Python backend also invokes `bin/hash` through a
+shell with a path argument. A port needs bounded path validation, secure
+extraction/cleanup, safe subprocess arguments, format coverage and actual
+Decky/backend tests before its official ZIP can be transformed or installed.
+
+The official archive still contains an x86_64 helper. RetroAchievements
+login, real ROM scanning, a packaged ARM64 backend, wearer-visible VR and
+physical controller use remain unverified.

+Intel Mac. It merged at main commit
+`035c59ee1134aa158c3cd818e8dd35f822cbfc4b`. The seven-job post-merge
+main [checks run](https://github.com/saphid/frame-control/actions/runs/40342375912)

+exact-version real Frame smoke: **12 passed / one optional x86 launch skipped /
+zero failed**, with owned cleanup and lock release. The x86 launch needs Steam
+Linux Runtime 4, which was absent. The headset was in standby and no wearer was
+confirmed, so the interactive worn-check script was not run. No panel or
+physical-controller claim follows from the smoke.

+fresh ten-line list regenerated from GitHub asset metadata byte for byte;
+its SHA-256 was

+### Actual Decky backend shim gate
+
+Fake-Frame tests stub plugin execution, so they cannot prove Decky's Python
+calling convention. `Decky backend runtime` CI separately runs the published,
+SHA-256-pinned **Decky 3.3.0** executable on native amd64 and ARM64 Linux.
+The loader discovers production-managed official archives and calls their public
+methods over its actual websocket API. No test imports or instantiates `Plugin`.
+
+```sh
+python3 scripts/framey-test-decky-runtime.py --output /tmp/decky-runtime.json
+# Offline loader cache (still checked against its pinned native digest):
+python3 scripts/framey-test-decky-runtime.py --loader /path/to/PluginLoader --output /tmp/decky-runtime.json
+```
+
+Run on Linux with Docker. Image build and the pinned loader download need network;
+plugin execution has no network, published ports, host home/audio/D-Bus/device
+mounts, capabilities or writable repository. Each case has its own unprivileged
+container, private tmpfs home and temporary files. Nothing contacts the headset
+or its shared lock. Failed/timed-out containers and the private image tag are
+removed by the runner.
+
+Every `compat_shims.append` in the managed installer must have a case in
+`tests/decky-runtime/cases.json`. Add each affected pinned official archive and
+a safe public-method probe when introducing a shim. Ordinary unit tests reject
+uncovered shim names. The runtime job verifies the managed receipt, loader
+plugin discovery, and a successful backend call; a discovery listing alone
+could conceal a crashed backend process.
+
+Current cases cover both Music Control entries and Shotty. Music Control uses
+the private silent MPRIS fixture to check discovery, metadata, play/pause,
+next/previous, seek and volume, with independent service-state readbacks.
+Shotty checks backend import, rescuer state and empty screenshot aggregation
+inside its disposable home. A fourth negative-control case deliberately
+reintroduces #335's incorrect bound-method transformation and must reproduce
+the real loader's legacy backend-call failure. The gate fails if that regression goes
+undetected. These checks verify backend behavior in a container; they do not
+upgrade any plugin's Frame, actual media playback or worn-VR compatibility claim.

+# Silent MPRIS runtime fixture
+
+`player.py` implements the synthetic target used by the
+[Music Control runtime evidence](../../../docs/evidence/framey-mpris-runtime-2026-10-26.md).
+It produces no audio. It requires system Python `dbus`, `gi` and GLib, and writes
+its independent control state to `/tmp/mpris-state.json`.
+
+Run it only in a disposable container with **no network, devices, host home,
+audio or D-Bus mounts**. Create a private session bus listening at
+`/run/user/<container UID>/bus`: both official backends hard-code that path.
+Set `DBUS_SESSION_BUS_ADDRESS` to that private socket for the fixture. Use a
+private home including `.local/share/Steam/steamui/images`, because the upstream
+plugins create an album-art symlink on startup. Never run these plugins against
+a real user's player during this test: ID111 probes volume automatically.
+
+Install each pinned archive separately through the managed transaction, then
+start the published Decky 3.3.0 loader with private `UNPRIVILEGED_PATH` and
+`PRIVILEGED_PATH`. Do not instantiate the legacy Plugin class: invoke methods
+through Decky's `loader/call_legacy_plugin_method` route with its keyword object.
+The two official entries share the `MusicControl` folder, so cannot coexist.
+This fixture is opt-in and is not imported by ordinary unit tests.
