+# 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.

-# Music Control 1.1.7 bound-method compatibility, 26 October 2026
+# Superseded: Music Control bound-method fixture
 
-The official Decky store archive for ID 111, version 1.1.7, is
-`3f56a3f56034b277ea74a2c37cc84133b69e382aa6bcb0b43876776aac737ed9`
-(SHA-256). The pinned `tests/fixtures/framey-official/111.zip` matches that
-digest and includes the upstream license.
+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
+and transport.
 
-The unchanged backend fails before it reaches D-Bus: `sp_list_media_players`
-raises `TypeError: Plugin._get_dbus_env() takes 1 positional argument but 2
-were given`, and `sp_play` raises the corresponding `_sp_player_dbus` argument
-error. The source passes `self` explicitly to methods already bound by Python.
-
-For this exact store ID, archive digest and folder, a managed install removes
-the redundant argument at the five affected call sites. It checks the number
-of occurrences before writing `main.py` and records
-`music-control-bound-methods` in the managed receipt. The original ZIP remains
-the verified download; the older ID 12 archive is installed without this
-change.
-
-`test_exact_music_control_backend_calls_work_after_managed_install` installs
-the official ZIP through the production transaction script into a disposable
-home. It imports the patched backend and exercises player enumeration,
-selection, play/pause, next/previous, volume and playback-status calls against
-a private fake `dbus-send` executable that records the actual command
-arguments. It then removes the plugin through the receipt-bound transaction.
-The same test confirms ID 12 retains its original backend source. The focused
-store suite passed **23/23** tests locally. The pinned frontend/fake-Frame
-install/remove tests are part of the hosted gate.
-
-This proves that the Python argument mismatch no longer prevents backend
-command dispatch in the isolated fixture. The fixture is not an MPRIS player.
-Actual Decky 3.3.0 ARM64 execution, live player discovery, media transport,
-volume effects, album-art routing, and wearer-visible VR controls have not
-been verified. Music Control remains **partial**.
+The follow-up [real runtime checks](framey-mpris-runtime-2026-10-26.md) reproduce
+the regression, remove the incorrect transformation and replace the test with
+the actual legacy calling convention. They also identify and repair a separate
+Frame OS system-command library-path failure. Existing copies installed with
+`music-control-bound-methods` must be removed/reinstalled or explicitly updated.
+Both official Music Control entries remain partial; the follow-up describes
+exactly what passed and what remains unverified.

+# 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.
