+**Steam library failures (GitHub #21/#30):** on some Frames Steam never loads FramePort's shortcuts.vdf entries (same SteamOS build and arm64 beta client as the dev Frame; IDs correct; file written before Steam starts): Play → console_log `GameAction [AppID <id>] … RequestingLicense → UpdatingAppInfo → LaunchApp failed with AppError_9` (= "Game configuration unavailable", Steam treats the id as a store app). Cause unknown; agent v42/43 diagnostics: `launch` returns `steam` (started / error + code / silent from console_log), `collect_diag` adds `steam_library` (real Steam dir, beta, Steam start vs vdf write time, entries per account, devkit games) + `steam-console.txt` (incl. Steam's `logs/shortcuts.previous.txt` if present; steamclient.so has "LoadShortcuts: rejecting attempt to load shortcuts: invalid account ID"). **Fallback (agent v43):** when Play gets AppError_9 the agent registers the game through Steam's devkit interface (what Valve's Devkit Management Tool does, MIT: `devkit-1 steam://devkit-1/<~/.steam/steam.token>/create-shortcut?response=<file>&gameid=<id>&directory=~/devkit-game` written to ~/.steam/steam.pipe; answer file / `.error`; `~/devkit-game/<id>/launch.sh` = link to the game's launch.sh, `<id>-argv.json` ["launch.sh"] (relative to the folder), `<id>-settings.json` {steam_play 0, compat_tool ""}). Steam adds it live (no restart), picks its own appid (read back from shortcuts.vdf by DevkitGameID), shows it as a normal non-Steam game named "Devkit Game: <id>" (OpenVR 0, but VR works: owner-verified 2026-10-04), art copied to grid/<appid>*. Ids: letter first, then letters/digits/_ only (spaces, '-', leading digit → "missing/invalid arguments"). Later Plays use the devkit entry; uninstall (`devkit_unregister`, `delete-shortcut` live) and purge remove it. Verified on the dev Frame: register/launch/unregister; the AppError_9 trigger itself only in unit tests.
+**Exit game (GitHub #36, 2026-10-04):** `Apps.TerminateApp` (what Exit game calls; reachable for tests through Steam's CEF devtools on 127.0.0.1:8080, SharedJSContext, `Runtime.evaluate` — a stdlib websocket client is enough) closed both a normal shortcut and a devkit entry on the dev Frame within 1-3 s. SIGTERM to Steam's `reaper` alone left launch.sh + Lepton (setsid) + the container running (an earlier headset launch ran on for 87 min); SIGTERM to launch.sh cleans up in ~4 s. Agent v44: launch.sh's 2 s loop ends the game when its parent (the reaper) is gone; `upgrade_launchers` (from ensure_host_fixes) adds that to existing launchers in place. Which in-headset exit path fails is still unknown. Screenshots on the Frame: all under SteamVR's appid 250820 (`760/remote/250820/screenshots`, screenshots.vdf has creation time, no game).
+**SteamVR dashboard at game start (2026-10-04):** the dashboard (Resume game / controller / VR options) was open whenever a FramePort game started (also over Lepton's 2D launcher). Steam's UI exposes `SteamClient.OpenVR.VROverlay.{IsDashboardVisible,HideDashboard,ShowDashboard}` (CEF devtools, `steam_js` in the agent). Agent v44: launch.sh starts `_dashboard_worker` (waits for FrameBridge's first `pacing:` line in launch.log, then hides a visible dashboard for 25 s, at most 3 times; log `<base>/dashboard.log`; opt out with env FRAMEPORT_KEEP_DASHBOARD=1). Verified on the dev Frame (dashboard shown → 4XVR launched via Steam → hidden ~5 s after the first frames); not yet seen in the headset.
+**Space warp / ITR2 (2026-10-04):** Into The Radius 2 (UE5, `libUnreal.so` + OVRPlugin, Vulkan) uses Application SpaceWarp (extra swapchains `376x376 format=97` motion vectors + `format=129` depth); #35 reports flickering textures. OVRPort's `patch_disable_space_warp` has no effect on UE5, and hiding XR_FB_space_warp in FrameBridge's enumerate doesn't reach the game either: **OVRPort's dispatcher offers/enables XR_FB_space_warp itself**. FrameBridge `hide_space_warp` (per game, off) hides it and strips `XrCompositionLayerSpaceWarpInfoFB` (1000171000) from the projection views (log `hide_space_warp: removed space warp info`); the game still renders its MV swapchains. Test build installed on the dev Frame; flicker not yet checked in a headset. Heuristic: UE5 + OVRPlugin shows it as an option (off). `equirect_emul` is suggested for Unreal games whose graphics API isn't detected ("GLES or unknown"); on Vulkan it switches itself off (Myst/Riven/ITR2): harmless, but Unreal Vulkan detection is a known gap.
+**PR #34 (merged 2026-10-04, Lucas-Mathieu):** `native/adapter/audio_metadata.h` patches Meta XR Audio Wwise (only build ID e1619e7f…, Batman: Arkham Shadow 1.4.1) so queued audio metadata isn't freed while the current audio frame references it (smoke-bomb crash). Verified headless: installs ("metadata reclamation follows …"), 72 fps; we added a once-per-second scan limit. Outside PRs: review source, rebuild `artifacts/` ourselves, merge locally (contributor's commit kept), push main.
+**Heuristics eval (2026-10-04):** `scripts/eval_heuristics.py "<VR CyberDeck Portable>"` → 19/44 recipes exact, 322/352 fields (most diffs: `frame.unity_text_input` suggested where older catalog recipes lack it; the rest are runtime-only findings: use_alt, vk_shader_fix, focus_hold, sync_guard, multipass). `PATCHED/` copies aren't scored (already converted).
+**Power (0.9, agent v47):** sidebar bar above the Frame card: Sleep / Restart / Shut down, each confirmed (`app.frame_power`, a running game asks again). logind answers CanSuspend/CanReboot/CanPowerOff = "challenge" for an SSH session but "yes" inside a user unit, so agent `power` runs `systemctl suspend|reboot|poweroff` from a transient `systemd-run --user --on-active=3` timer (the command answers first). Restart verified on the device (back in ~84 s, new boot id).
 **Lepton storage (2026-09-30):** each app's /sdcard (= /storage/emulated/0 → `<base>/lepton-data/external`) has `Movies`/`Download`/`Documents` symlinked to the Frame's `~/Videos`/`~/Downloads`/`~/Documents` (liblepton/mounting.sh, only if they exist at start); agent v24 `storage_targets` reads that mapping. Android's MediaProvider canonicalises paths to /home/steamos/... and rejects every file ("doesn't appear under [/system/media...]"), `sm list-volumes` is empty: the media index never works, apps must browse folders. Lepton installs with `adb install -g` (runtime permissions granted, MANAGE_EXTERNAL_STORAGE too). Files: `install/files.py`, `frameport frame send|storage`, GUI Files tab (formerly Frame → Send files).
 **SteamVR per-app settings (2026-09-30):** editing steamvr.vrsettings while SteamVR runs is lost; the web API (127.0.0.1:27062 /app/setsettings) needs `x-steamvr-secret`. `native/vrsettings` = `fp_vrsettings.exe` (freestanding, OpenVR `FnTable:IVRSettings_003` as a Utility app, loads SteamVR's bin/win64/openvr_api.dll) sets them live and SteamVR persists them: section `steam.app.<shortcut appid>`, keys `preferredRefreshRate` (float) and `motionSmoothingOverride` (0 global, 1 on, 2 off, 3 always). Steam Link (vrlink) lists the Frame's rates 72/80/90/96/108/120/144 in vrserver.txt and follows the per-app preference ("host preferred N Hz"; whether the key is honoured is unverified in-headset yet). Judder metric: vrcompositor.txt session summary dropped + "Timed out. N total" (Stormland: 0 dropped but 313 timeouts in 2 min); fpsVR (`%LOCALAPPDATA%\fpsVR\*.json`, 0.1 ms histograms) gives p99 CPU/GPU ms. `pcvr.steamvr_tuning` (default on, PC only) applies on Play: highest rate whose budget ≥ p99×1.05, at least one step down, smoothing on.

+**Language packs (merged from PR #20, 2026-10-04):** overport's `libovrplatformloader.so` is a dispatcher that `dlopen`s Meta's own loader (`libovrplatformloader_meta.so` / `_meta_q1.so`, also `libpxrplatformloader.so`) and keeps its own message queue; `ovr_LanguagePack_GetCurrent/SetCurrent` are 8-byte `return 0` stubs in it, `ovr_AssetFile_GetList` forwards to Meta's loader. `frame.langpacks` (opt-in, `native/langpack`) serves `<tag>.lang` files from the game's data; `elf.hide_exports` marks the loader's exports STB_LOCAL (bionic and glibc only match GLOBAL/WEAK; verified for glibc, bionic's `is_symbol_global_and_defined` is from memory). `libfp_langpack.so` is built here (`python native/build.py --only langpack`) and committed. Owner-verified 2026-10-04: Deadpool VR with only `en.lang` and the patch on plays English dialogue and runs normally (headless launch tests show 2-6 fps while it loads: not a regression sign). A dispatcher answer that arrives after we answered the timed-out GetList is dropped (one answer per request); games already in a library get `lang_packs` filled after an app update (`library._refresh_data_fields`). The library logs to logcat under the tag `fp_langpack` (dirs looked in, packs found, every language-pack call), so it shows up in the game's `launch.log`; an `ovr_AssetFile_GetList` the dispatcher leaves unanswered for 1.5 s is answered with our packs alone. Deadpool VR (Unreal) accepts a pack only when its `Metadata` equals the game's own version string (`ULanguagePacksSubsystem` compares it with `%s.%s.%s.%s.%s` built from the build info, e.g. `1.0.40.356975.Quest` = versionName; found by disassembling `libUE4.so`): the patch writes the APK's versionName into the library (`@FPMETA@` slot, `with_metadata`), `FRAMEPORT_LANGPACK_META` overrides it. Deadpool VR (2026-10-04, headset): German became selectable with that Metadata, but dialogue stayed silent (even English once reported as a pack) while the path was spelled `/sdcard/Android/obb/<pkg>/x.lang`; with the `/storage/emulated/0/Android/obb/<pkg>/x.lang` spelling (Unreal's own, now listed first in `scan_dirs`) German dialogue plays. `FRAMEPORT_LANGPACK_SKIP=<tags>` or a file `fp_langpack_skip` in the obb folder leaves packs out of the list (experiments).

+# Meta XR Audio metadata lifetime
+
+FrameBridge automatically handles metadata retirement in the verified AArch64
+Meta XR Audio Wwise build (`e1619e7fb839badf0ea5ecc22d9f028d0b17c34d`). It requires
+the build ID and exact function prologues; other builds and 32-bit adapters are
+left unchanged. No additional patch switch or recipe entry is required.
+
+The SDK queues terminated metadata for deletion, then drains those queues before
+reading the current `AkAudioObjects` snapshot. In Batman: Arkham Shadow, that
+snapshot can still reference queued metadata during smoke-bomb playback. The
+audio thread subsequently clears its dirty flags at offset 8 through the stale
+pointer. A hardware watch captured this store in
+`OculusEndpointSink::ConsumeObjectExperimentalMetadata`, at library offset
+`0x2ced90`. Reallocated input tree nodes occupy the same 48-byte size class;
+the stale store corrupts their right pointer and the game crashes later.
+
+`native/adapter/audio_metadata.h` wraps the audio consumption boundary to make
+the current snapshot available to metadata cleanup. `audio_metadata_queue.h`
+retains queued objects still referenced by that snapshot, then reclaims them
+normally when the references disappear. It preserves the SDK's queue mutex,
+virtual deleting destructor, audio parameters and processing. There is no timed
+quarantine, replacement allocator, audio suppression or diagnostic memory arena.
+
+Synthetic regression tests exercise mixed referenced and unreferenced queue
+entries, both metadata types, subsequent retirement, and cleanup without a live
+snapshot. On-headset smoke-bomb tests first showed the observed overwrite stopped,
+then passed with ordinary allocations and all memory diagnostics removed.
+
+The existing `frame.adapter` install step includes the repair in its packaged
+adapter and updates already wrapped APKs. Rebuild the adapters and checksums with
+`python native/build.py --only adapter`.

Unreal's OculusHMD and LibOVR's `ovr_Detect` only start when the Windows named event `OculusHMDConnected` exists and is signalled (the Oculus service creates it). `fp_oculushmd.exe <command line>` creates it (manual reset, signalled), runs the command (Revive's injector) in a job object and keeps the event until every process in the job — the game and its children — has exited (fallback without job support: 3 minutes); returns the command's exit code and logs `FramePort oculushmd: …` to stderr (launch.log). Freestanding Windows x64 console exe (no CRT, no Windows SDK): the NDK's clang + `lld-link /Brepro` with a kernel32 import library generated by `llvm-dlltool`, so it's byte-reproducible. Tested on Windows from WSL with a build whose event name is `-DEVENT_NAME=L"…"` (the Oculus service owns the real event on a PC with the Oculus app). |

+// FramePort language packs: answers the Meta Platform SDK's language-pack calls from `*.lang` files that already
+// sit in the game's data (OBB / app files), without any download.
+//
+// Why: OVRPort's libovrplatformloader.so is a dispatcher in front of Meta's own loader (…_meta.so). It answers
+// ovr_LanguagePack_GetCurrent / ovr_LanguagePack_SetCurrent with `return 0` (request id 0, no message ever comes
+// back), so a game that asks for its language pack waits for an answer that never arrives.
+//
+// How it is wired (patch frame.langpacks):
+//   * this library becomes the first DT_NEEDED of the dispatcher;
+//   * the dispatcher's own exports of the functions defined here are marked STB_LOCAL in its .dynsym, so symbol
+//     lookups (the game's imports and dlsym on the dispatcher's handle) continue to this library;
+//   * everything we do not answer ourselves is forwarded to the dispatcher's original function, found at run time by
+//     reading the dispatcher's in-memory .dynsym (the entries are still there, only no longer visible to lookups).
+//
+// What it implements (see https://developers.meta.com/vr/documentation/native/ps-language-packs/):
+//   ovr_LanguagePack_GetCurrent / SetCurrent        answered here
+//   ovr_AssetFile_GetList                           the dispatcher's list + our packs (type "language_pack")
+//   ovr_AssetFile_StatusById                        answered here for our packs (always "installed")
+//   ovr_PopMessage, ovr_FreeMessage, ovr_Message_*, ovr_AssetDetails*_*, ovr_LanguagePackInfo_*,
+//   ovr_AssetFileDownloadResult_*, ovr_Error_*      wrappers: our messages/handles are served here, any other
+//                                                   handle goes to the dispatcher unchanged
+//
+// Where the packs are looked for (first file per tag wins; depth <= 3):
+//   $FRAMEPORT_LANGPACK_DIRS (':'-separated), otherwise
+//   /sdcard/Android/obb/<pkg>, /sdcard/Android/data/<pkg>/files, the same under /storage/emulated/0, and
+//   /data/steam_app/obb (where Lepton mounts the host's obb folder)
+// A pack is a regular file named <BCP47 tag>.lang (de.lang -> tag "de").
+//
+// Which pack is "current": the one the game applied with SetCurrent; else $FRAMEPORT_LANGPACK (a tag); else the only
+// pack if there is exactly one.
