frame.unreal_thumb_touch: UE4 OculusInput's ThumbUp from the capacitive touches instead of near-touch, which the Frame never reports (thumbs always pointed up). Three instructions in SendControllerEvents (masks 0x2/0x8 -> 0x0f00/0x000f, NearTouches load -> Touches), matched exactly; suggested where the code matches (analysis unreal_thumb_touch, ANALYSIS_VERSION 7): Vader Immortal Ep. I, Robo Recall, Phantom: Covert Ops, Time Stall, Star Wars: Tales. Vader's recipe uses it instead of proximity_emul (the binding didn't animate the thumbs). Found by Klownicle, GitHub #49

Mesa enforces OVR_multiview's rule that a draw's program declares as many views as the draw framebuffer has and drops the draw silently; Doom3Quest compiles every vertex shader with layout(num_views=2) and draws its HUD/PDA into 2D-texture FBOs, which stay black on the Frame.

native/glmv (libfpglmv.so, same length as libGLESv3.so): the engine library's dlopen string is rewritten to it and it becomes the first DT_NEEDED. It records stage sources at link time and, when a multiview program draws into a framebuffer without views, draws with a lazily built single-view twin (num_views layout blanked, gl_ViewID_OVR -> 0u; attribute locations, block bindings and uniform values copied), then rebinds the original. Opt-in and experimental (analysis gl_multiview_libs, ANALYSIS_VERSION 6), setting gl_mv_debug, triage gl-multiview-twin-failed.

Host tests: the rewriter on Doom3Quest's 19 shaders (GPL-3.0 fixtures) and glmv.c against a stand-in GL that applies Mesa's rule. Untested on the device.

+Remembered Frames are found again after an address change (`Frame.relocate`: scan, same SSH host key, before
+login). Packaged apps show artwork by file path (`thumbs.use_file_paths`, #16). Diagnostics: this boot's kernel log.
+Device tests of requested games (2026-10-04, headless): I Am Cat, Myst 3.3.0, BattleGlide, Blade & Sorcery: Nomad
+start (RUNNING, frames). Roblox: SIGSEGV in je_free from libroblox.so ~3 s in (likely its anti-tamper vs the re-signed
+APK). BONELAB (Unity 2021.3 Vulkan, OVRPlugin 1.94): SIGSEGV with pc == fault addr in vkCreateInstance, called from
+libSLZQuestNative.so's Vulkan hooks into an unmapped (unloaded) library right after OVRPlugin's pre-init
+xrDestroyInstance; pinning openxr/vrclient libraries (RTLD_NODELETE) did NOT help — find the unloaded library with the
+linker's dlopen/dlclose logging next. Accounting+ (Unity 2017.4 built-in Oculus, libOVRPlugin + libvrapi): Unity
+never starts VR on the Frame (no OVRPlugin/OpenXR lines; runs as a 2D app), which is why its "controller setup"
+screen can't be passed — Unity 2017's Oculus device check, not the controller profiles. Cpp2IL can't read Unity 2017.
+The Frame's Android runtime (vrclient.so) knows oculus/touch_controller but not Meta's Touch Plus/Pro profiles
+(OVRPlugin suggests those too, routinely) → adapter `profile_remap`.
+Headset round 2 (2026-10-04): the Frame drops focus often (ms to 7 s; only some are presence/standby) → games pause
+or recentre (B&S Player.OnVRPresence → Teleport, BattleGlide/Unreal pauses); focus_hold now 1 s focused / 1 s max dip
+(longer must still pause). Myst crash = vrclient xrSyncActions race after FOCUSED → `sync_guard` (confirmed); its
+object glitches: app space warp suspected (FB_space_warp is advertised and used) → recipe `patch_disable_space_warp`.
+I Am Cat multipass: poses/times consistent, but every frame is submitted after the next xrWaitFrame (one period late;
+Zink + doubled draws) and the game clamps its physics step to 10 ms → judder while still; testing scale 0.8. Roblox's
+newest crash is on Fossilize's recording thread → vk_sanitize extended to own-engine libs (engine "Other").
+Accounting+: unity_oculus_check + native/ovrpshim (libfp_ovrp.so waits via ovrp_WaitToBeginFrame before Unity
+2017's ovrp_Update2) → VR in the headset at ~72 fps (2026-10-04), but stuck at "press any button" although input
+reaches its OVRInput cleanly (probe: both Touch connected 0x63, individual buttons, input focus 1) → works with issues.
+"outside of frame bounds" warnings stay (~2/frame) and are harmless.
+Steam library (GitHub #4/#21/#27, agent v38): shortcuts go to every Steam account (signed-in first; MostRecent isn't
+always the account on the Frame); stop_steam also waits for Steam's helpers; after the restart the agent re-reads
+shortcuts.vdf and writes once more if Steam put its old copy back (`shortcuts_lost`), else reports it. 0.6.3's Play
+auto-repair (`_add_then_play`) crashed (its job got a Job, not a reporter). Uploads resume on a transient OSError.
+Lepton's Android 11 has no clipboard service (134 services; checked with `podman exec … service check clipboard`):
+SDL/LÖVE apps crashed at start → `frame.sdl_clipboard` (`apk/dex.py`: in-place dex edit, nops one invoke, fixes
+the header checksum/signature; verified with LÖVE for Android 11.5, GitHub #24 Dramatic Shape). 2D apps (vr_kind none)
+keep every suggested patch that isn't about VR (`needs_vr = False`), not a fixed list. FramePort on the Frame:
+`frame/local.py` (127.0.0.1, own key authorized; "This Frame (experimental)"; app data in
+~/.local/share/frameport-app because ~/.local/share/frameport is the agent's) and Steam library changes wait while
+Desktop Mode is open. Verified on the device 2026-10-04 (install + launch test from the Frame). Library updates on the
+Frame run one at a time (agent v40 flock): two quick uninstalls used to bring a removed shortcut back (Roblox).
+Headset round 3 (owner's verdicts, 2026-10-04): Blade & Sorcery works — its freezes were the headset's wear sensor
+flickering off while worn (vrserver.txt "HMD off/on" 0.5-2 s) → per-game `focus_hold_ms=2500` (only this game reacts;
+not a default). BattleGlide works (focus_hold). Myst works with issues (object glitches; space warp ruled out, its
+recipe keeps it on). I Am Cat works with issues (judder; scale 0.8 no help). Roblox unsupported (je_free in
+libroblox, also with the Vulkan shim). Installs skip the Steam restart when the shortcut is unchanged and wait while a
+game runs (agent v37). New default fixes in FramePort's code reach games already in a library: after every app update
+`library._follow_catalog` re-derives each non-user recipe once (setting `recipes.app_version`; tests switch it off via
+`library.REFRESH_ON_UPDATE`). Analysis fields added later: **bump `analysis/detect.ANALYSIS_VERSION`** (stored as `analysis.extra.analysis_version`); older entries whose APK is still there are analysed again at the GUI's start (background thread, not a job: ~8 s per 900 MB APK) and before a build (`pipeline.refresh_analyses`, GitHub #104); only `analysis`/`suggested` change, user recipes stay; an unreadable APK gets `analysis_failed` = the version (not retried until the next bump). Troubleshooting techniques: docs/PLAYBOOK.md "Debugging techniques". Unity `boot.config` "vulkan" substring mislabels GLES games as Vulkan
+(I Am Cat ran GLES); OVRPlugin's "Unavailable OpenXR extension: XR_FB_scene" is routine (no longer triaged).
+**Round 4 (2026-10-04):** XR_KHR_android_surface_swapchain is listed by the Frame's runtime but returns
+FUNCTION_UNSUPPORTED → adapter `surface_emul` (default on, `native/adapter/surface_swapchain.c`): an ordinary runtime
+swapchain is returned, the game gets a Surface from a SurfaceTexture on a worker thread (own EGL context, JavaVM from
+XrInstanceCreateInfoAndroidKHR), frames are read back (glReadPixels) and uploaded in xrEndFrame (Vulkan: own command
+buffer + fence per panel, never waits; GLES: glTexSubImage2D). I Am Monkey's intro works (owner-confirmed). SUPERHOT
+(Quest) quit at start: its cloud save folder was mode 1700 and Lepton's app writes through the folder's group →
+launch.sh `fix_perms` adds u+rwx,g+rwx (agent v41). Lucky's Tale: Unity's Loading.PreloadManager thread grows the
+native heap ~1 GB/s until the OOM killer (Frame freezes); no fix. `perf` works as steamos (paranoid 2; ptrace_scope 1
+blocks gdb/eu-stack/debuggerd) — see PLAYBOOK "Debugging techniques". QuestCraft downloads its JRE at first run into
+`files/runtimes/JRE` (Pojlib Installer); on the Frame it was missing (unpacked by hand, unverified). WiiCompiled: its launcher shows
+(lepton-show-flatscreen) but imports .wcgame files through Android's document picker (OPEN_DOCUMENT), which Lepton
+lacks (ActivityNotFoundException) → imported by hand: libmain.so + game.json → internal files/game/<profile>,
+DATA/ → external files/WiiCompiledOpenXRVR/DATA, MOD/ → .../RetroRewind6 (decompiled with jadx). Lepton has no
+picker at all: a FramePort fix would be an injected picker activity. Generated cover/banner art used to suppress the
+Steam placeholder set (no Steam art at all) → fixed in artwork/steam.py.
+**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. GitHub #42 (two Steam accounts, neither MostRecent): Steam rewrote the active account's shortcuts.vdf without FramePort's entries right after starting, and added the devkit entry live without saving it, so `devkit_appid` (vdf only) failed ("Steam added the devkit entry but didn't save it"); agent v55 `devkit_appid_from_log` reads Steam's `sanitize shortcut app id "~/devkit-game/<id>/launch.sh": replacing 0 with N` console line. GitHub #41 (one account): same Steam behaviour, and every install restarts Steam, which forgets the never-saved devkit entry. Agent v56: the log fallback reads only the current session's console_log.txt; Play re-registers a devkit entry that gets AppError_9; art updates also write the devkit entry's grid art (`copy_grid_art`). Open: why some Frames' Steam never loads or saves shortcuts.vdf (single account too).
+**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. **Headset (ITR2, 2026-10-05): too late** — Steam shows its frame menu (`valve.steam.gamepadui.frame.menu`, vrwebhelper_systemui.txt `[PooledPopups] Showing`) ~0.3 s after the game's first submitted frame (FrameBridge `new layer:`), but the first `pacing:` summary comes ~8 s later; the owner had pressed Resume (`[HideDashboard] return_to_game`) before the worker looked. Agent v52: watches from the first `new layer:` line (incremental log reads, 0.5 s polls, 30 s window). Agent v59: watches 120 s and hides up to 10 times (the menu came back after 30 s in the owner's sessions). Agent v53: stops for good once the player opens the dashboard with the controller (`toggle_dashboard_action` in vrwebhelper_systemui.txt since the worker started): v52 closed it 60 ms after each press, and the game, paused for it, stayed paused.
+**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 below 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).
+**Proton default (agent v51, owner's choice 2026-10-05):** the newest **stable** ARM64 Proton is the default for PC VR games (`pick_proton`: asked-for name/alias, else newest installed stable, else any stable). Agent v49-50 defaulted to Experimental; the owner's headset A/B with Rick and Morty (Experimental 69 % reprojected frames, stable felt much smoother) reverted it. The game page's Customize shows `pcvr.proton_tool` as a dropdown (Stable (default) / Experimental = alias `proton-experimental`); `ensure_proton` installs a chosen one (it asks once more for the runtime Steam only names after Proton is installed; Experimental installed unattended on the device in 53 s). A PC VR launch test that fails on stable suggests Experimental (`pipeline.PROTON_TOOL`, `proton_alternative_worth_trying`, button "Try Proton Experimental and reinstall"). Remaining Rick and Morty stutter on head turns = the game rendering below the refresh rate (reprojection), not Proton.
+**USB cable link (verified 2026-10-05, cabled to the dev PC):** `usb0` is a USB **NCM** gadget (configfs g1: `ncm.usb0` + `ffs.adb`, Valve 28de:2460) set up by `usb-ncm-gadget@usb0.service`, which only runs with `ConditionPathExists=|/etc/systemd/system/adbd.service.d/steamos-devkit-enabled` = **Developer Mode only**. `usb-ncm-dnsmasq@usb0` serves DHCP with fixed `dhcp-host` entries: Frame 10.86.200.233, PC **10.86.200.234** (`frame/usb.py` FRAME_USB_IP/PC_USB_IP). Windows 11 binds its built-in "UsbNcm Host Device" (no driver); WSL mirrored sees eth 10.86.200.234. USB is high-speed (USB 2.0): upload 36.9 MB/s vs 11.3 MB/s home Wi-Fi. Frame→PC over the cable worked without a firewall change. `scripts/usb_autotest.py` (Windows via powershell.exe from WSL), `frameport frame usb-check`. Wizard "Set up with a USB cable" (`PairingServer(host=PC_USB_IP)`; the real bootstrap ran end to end over USB). Discovery dedupes by SSH host key and prefers USB > Frame hotspot > network (`discovery.dedupe`); a lost address is re-found by key (`Frame.relocate`, tested with a dead saved address).
+**Catalog updates without a release (2026-10-05):** apps fetch `catalog/games/*.yaml` from GitHub `main` (`recommend/catalog.refresh_remote`: one API call `git/trees/main?recursive=1` + raw.githubusercontent downloads of changed blobs, cached as `catalog-gh-<sha>.yaml`, every 6 h; GUI at start + Settings → Data "Check now"; CLI background thread + `frameport catalog-update`). `catalog.load()` only reads the cache. A remote entry is skipped (`unusable_reason`) when it names a patch/adapter key this app doesn't register, has a field `CatalogEntry` doesn't know, or `min_app` > this version: add `min_app` (or rely on new patch ids) when a config needs an unreleased FramePort. Remote beats bundled unless the bundled entry has a later updated/verified date; the user's own entries still win as before. Off: setting `catalog.auto_update`, env FRAMEPORT_NO_CATALOG_UPDATE; FRAMEPORT_CATALOG_URL still overrides the source. So: **pushing a catalog change to main reaches users within 6 h** (their recipes follow via catalog_rev → Update on Frame).
+**Start activity / QuestCraft / ITR2 pop-in (2026-10-05):** WiiCompiled's VR part (`QuestActivity`, SDL, process `:game`) stays behind Lepton's flat window when the launcher is shown (`device.text_input_window`). `frame.start_activity` (opt-in; analysis `extra.vr_activity` = the original APK's activity with Meta's VR category when it isn't the launcher) gives that activity's filter LAUNCHER and every other LAUNCHER becomes INFO, per element (`axml.set_start_activity`); Lepton's own `apk-info-extractor --print-activity-name` (on the Frame under Lepton/liblepton/apk_extractor) then answers QuestActivity. **OVRPort gives every MAIN activity LAUNCHER + VR categories**, so the VR activity must come from the original APK's analysis, not the converted manifest. Lepton has no activity override (`APP_ACTIVITY` is reset when app_metadata.sh is sourced). QuestCraft reaches Minecraft 1.21.5 (Fabric, Vivecraft, Sodium; LTW "Large Thin Wrapper" GL 3.0 on the Frame's Zink) and stops at `OpenGL error 1282` in `WindowFramebuffer` createTexture (Minecraft's crash report in `files/instances/1.21.5/crash-reports/`, Pojlib's `files/latestlog.txt`); the vrclient SIGSEGV / "pthread_mutex_lock called on a destroyed mutex" afterwards is only the shutdown (Unity's render thread still in vrclient while the instance is destroyed). ITR2 "models popping in and out" in game: Unreal reads user config from **internal** storage (`lepton-data/internal/<pkg>/files/UnrealGame/<Project>/<Project>/Saved/Config/Android/Engine.ini`, not external); `r.AllowOcclusionQueries=0` there broke its menus (removed again). Vulkan shim `vk_query_slots` (two slots per occlusion query) never saw ITR2 create an occlusion query pool, and the run with it crashed (Unreal RenderThread SIGSEGV, caught by sentry-native: no tombstone; the backtrace is in `cache/sentry/*/.sentry-native/*.run/*.envelope` with module offsets) - left off. Next suspect: Unreal 5 mobile HZB occlusion reading depth stored with Valve's FDM injection layer; test = launcher `VK_INSTANCE_LAYERS=''` (Lepton then loads neither VALVE_rpo nor VALVE_fdm_injection, Fossilize still). QuestCraft: LTW overrides glGetError and returns 0 with `LIBGL_NOERROR` set; Lepton passes `LEPTON_ENV_<NAME>` to the app as `<NAME>`, so catalog `lepton_env: {LEPTON_ENV_LIBGL_NOERROR: '1'}` gets Minecraft past the GL error 1282; then black picture (see the catalog entry). FrameBridge logs `new layer` once per layer type per process and projection views only for the first frames, so a second session in the same process (Vivecraft after Unity) needs `layer_debug=1`.
+**Vulkan validation / ITR2 solved (2026-10-05):** Khronos' validation layer can't come from Lepton (its layer dir is in the read-only guest image; the Linux copies on the Frame are glibc) and a global `debug.vulkan.layers` property (via the LEPTON_GFXRECON_FP_PROPS trick) kills the container at boot. Working recipe: bundle `libVkLayer_khronos_validation.so` (Khronos android-binaries release, arm64-v8a, stored uncompressed) into a test APK re-signed with the game's key (`apk.sign.sign`), install with `frameport install <pkg> --apk`, and set the Vulkan shim's `vk_validation=1` (it adds the layer at vkCreateInstance; findings under the logcat tag VALIDATION in launch.log, each message ID capped at 10). ITR2's flicker + windows behind models = Unreal's Qualcomm shader-resolve subpasses with a depth resolve of a single-sampled depth attachment (VUID-04908/-03179); `vk_spec_fixes=1` drops that resolve (its TRANSFER_DST half never applies to ITR2: the main depth is transient). Valve's VALVE_rpo layer removed ITR2's fog (catalog `lepton_env: VK_INSTANCE_LAYERS: VK_LAYER_VALVE_fdm_injection`). `r.ViewDistanceScale=2` in the internal Saved/Config/Android/Engine.ini only exists on the owner's Frame (the catalog can't write internal storage yet). Launch tests: Lepton prints a transient "is not a running context" on the first start after an APK change (agent v54 `not_started` waits 30 s for "Boot complete!").
+**GitHub #38/#39 (2026-10-05):** PowerWash Simulator stuck at "Waiting.." on a reporter's Frame = Unity sized the right-eye image rect past its swapchain (rect 268+1656 on a 1920-wide swapchain; the runtime's recommended size differs per Frame) and SteamVR rejected every frame (`xrEndFrame failed -25`, XR_ERROR_SWAPCHAIN_RECT_INVALID), after which the game stopped calling xrEndFrame. FrameBridge `rect_clamp` (default on; sizes noted in xrCreateSwapchain; clamped layers count as swapped) keeps projection/quad rects inside their swapchain; triage `swapchain-rect-invalid`. Not reproducible on the dev Frame with `scale` (Unity's eye sizing isn't just the recommended width); no regression there (72 fps). The adapter's revision was NOT bumped (that would mark every installed game outdated): affected users rebuild. The Room VR (#38) = Unity's render thread SIGSEGV in libgallium_dri.so ~30 ms after the game recreates its eye swapchain with samples=4 (FrameBridge retries samples=1); the game's own code turns MSAA on (not OVRManager); candidate fix: hide GL_EXT_multisampled_render_to_texture (GL shim) - needs the APK to test. The launch test passed both (render thread dead / no frames): triage gap.
+**Headset round 2026-10-05 (evening):** I Am Cat's judder = repeated xrLocateViews of one display time returning
+slightly different poses → FrameBridge `pose_consistency` (owner-verified, works). Lucky's Tale freeze on touching a
+save slot = OVRPort's OpenXR dispatcher converting XR_FB_haptic_amplitude_envelope with ns read as s (GitHub #9) →
+xrshim `haptic_fix` (owner-verified); its remaining short pauses were the wear sensor ("HMD off/on" 0.5-1 s in
+`logs/eyetracking.txt`, not vrserver.txt) → **`focus_hold` is on by default with 5 s** (owner's choice; C defaults
+too). The Room VR works (`unity_no_overlay_copy`). BattleSisters (Unity 2019.4 built-in VR, no libOculusXRPlugin.so)
+flooded "outside of frame bounds" ~2400/s and hung the GPU (kernel hangcheck, zink DEVICE LOST) → the ovrpshim frame
+wait now also applies to Unity 2019 without the Oculus XR Plugin (`UnityOculusCheck.legacy_loop`). Vader Immortal
+(UE4, stuck on the loading image after the intro, GitHub #49): VRP repacks carry a Frida gadget (`libfrda.so`,
+config `hijack_responses`), but OVRPort's `patch_clean_up_frida` removes its loadLibrary call, so it never runs on
+the Frame; `frame.ovr_trace` (opt-in, `native/ovrtrace`: 1138 exported ovr_* stubs → real loader functions, logcat
+tag `fp_ovrtrace`: calls, PopMessage answers, unanswered requests every 10 s) is the next diagnostic.
+**Unity built-in VR input (2026-10-05):** probe builds (`FRAMEPORT_INPUT_PROBE=1 frameport build …`; it logs
+trigger/grip crossings too) showed OVRPlugin returns the full Touch state for every controller mask (also Go masks);
+presses reach the games' OVRInput. Accounting+ (Il2CppDumper v6.7.46 reads its Unity 2017 metadata v24, run on Windows)
+passes stance selection (NewtonVR grip/trigger) but its motion warning waits for `Input.GetMouseButtonDown(0/1)`,
+which Lepton never delivers (no focused Android window) → ovrpshim registers its own
+`UnityEngine.Input::GetMouseButtonDown(System.Int32)` icall (il2cpp_add_internal_call, after Unity's: resolve first)
+that adds a click in the frame a Touch trigger or A/B/X/Y is newly pressed (`unity_oculus_check` revision 3).
+BattleSisters (Unity 2019 InputSystem/XR InputDevices via `VrHandInput`): libunity's Oculus module (OVRPlugin
+function table: a global pointer at 0x16b57c0 in this build, slots filled by name, e.g. +0x160 GetControllerState,
++0x168 State2, +0xe8 GetNodePresent) only reports controllers when `strncmp(deviceModel, "Oculus", 6) == 0` (next to
+the Go check `deviceModel == "Oculus Pacific"`); Lepton's model is "Valve Lepton" → Go/unknown → only Go masks polled,
+buttons dead. `unity_oculus_check` revision 4 (`oculus_model_checks`, Unity 2019 only) turns the 17 compares' length
+into 0 (`orr w2, wzr, #6` → `mov w2, #0` after the adrp/add of the "Oculus" literal; the string stays: it is also
+Unity's VR device name). Device result: libunity now polls `ovrp_GetControllerState(0x3)` (Touch); owner-confirmed
+2026-10-06: buttons work. Its first controller vibration then hit OVRPort's haptic-envelope bug (11 GB, OOM kill) →

+Accounting+ works (owner, 2026-10-06).
+**Vader Immortal (UE4, GitHub #49, 2026-10-06, headless):** stuck after the intro on an in-game image (the splash
+quad ends ~6 s in; then the game's own projection frames, 72 fps, balanced xrBeginFrame/xrEndFrame). Not the Platform
+SDK (`frame.ovr_trace`: only user + entitlement, both answered) and not the repack's Frida gadget (OVRPort's

+BeginGPUTimingCommandBuffer` and `xrEndFrame → CVRCompositorClient::SubmitWithArrayIndexAndTime`. Ruled out: the
+layer color scale/bias + image layout structs (FrameBridge `strip_color_bias` 1/2, diagnostic), Valve's Vulkan
+layers (VK_INSTANCE_LAYERS=""), array swapchains in general (Lucky's Tale/I Am Cat flat). Kernel tracepoints aren't
+allowed for steamos. FrameBridge: `layer_debug` logs xrDestroySwapchain and per-5 s xrBeginFrame/xrEndFrame counts;
+`frame_balance` (ends an open frame before the next begin) exists but Vader never leaves one open. Next (built,
+not yet run: the Frame slept): `layer_debug` also counts xrAcquire/Wait/ReleaseSwapchainImage per 5 s (hooked only
+with layer_debug, after the other conditional hooks) to see whether Vader skips a wait or release: it doesn't (361/361/361 per 5 s).
+FrameBridge `snapshot=N` (`snapshot_gl.c`, GLES): every N s the left-eye image the game submits is read back on its
+own context and saved as `files/fb_snap_0-7.ppm` (quarter size) — headless launches show a black headset view, this
+shows what the game draws. Vader: Lucasfilm logo (an OBB mp4: video works), then its loading card (portrait + segmented
+bar) that never advances; the async loader thread sleeps and OBB reads stop (~168 MB of a 2.7 GB pak).
+**Lepton's logcat mirror dies (agent v67, 2026-10-09):** occasionally launch.log ends with `logcat: Unexpected EOF!` right after the game starts (about 1 launch in 50, Lepton 2.8.14 and 3.0.5): no dashboard auto-hide, no launch-test result. launch.sh's `_logcat_keeper` then reads `podman exec lepton-steamlaunch-<appid> logcat` itself into launch.log (up to 5 restarts while the game runs).
+**Double launch (agent v57, 2026-10-06):** a second Play while Lepton still boots (~10 s with nothing to see) made
+the second Lepton stop the first one's container ("Waiting for steamlaunch-<appid> (PID …) to exit", exit 137
+"(starting)", "Clearing baked app data due to early exit") and both died (Vader, BattleSisters). launch.sh now takes
+`flock` on `<base>/.launch.lock` (fd 9, inherited by Lepton; the watchdog and dashboard helpers close it with
+`9>&-`); a second launch exits 0 and logs to `<base>/launch-dup.log`. `upgrade_launchers` adds it to existing
+launchers. Verified on the device (second launch during boot: ignored, the first kept running). Vader on its loading
+card ignores input too (owner pressed/held every button: presses reach the runtime, the card never changes).
+**Issue triage round (2026-10-06, owner's headset):** vibration in OVRPlugin games = 2 s vibrations updated per frame and
+stopped with amplitude 0; FrameBridge turns amplitude 0 into xrStopHapticFeedback (else each buzz ran 2 s), haptic_fix
+uses the envelope RMS (was its peak), per-game `haptic_scale` → Creed/The Boys/Jurassic World fine. Lambda1VR (TBXR):
+loader named by Build.MANUFACTURER (`frame.tbxr_vendor`), no graphics extension enabled (FrameBridge adds
+XR_KHR_opengl_es_enable + asks for the requirements on -50), always multisampled render-to-texture (GL shim gives
+single-sampled stand-ins when GL_EXT_multisampled_render_to_texture is hidden) + its xash/ data → works. Jurassic World:
+`frame.vrapi_stub`. Metro Awakening: contributor's vkshim fixes + hide_space_warp + no VALVE_rpo (jumping polygons like
+ITR2). Pinball FX VR: hide_space_warp (stutters). Eleven: a Meta online request fails after platform init → needs Meta
+services. Star Wars Tales: top half black + freeze after loading; ruled out: asset-file paks (never requested), Valve
+foveation (off: no change), GL errors (MESA_DEBUG=1: none), EGL_BAD_ACCESS once in OVRPlugin init (harmless); the game's
+eye image reads back black. BlazeRush: VrApi bridge exports + ovr*_ToString stubs + avatar stub get it to the menu room
+at 72 fps, full input reaches it (diagnostics `input 5s`: Touch type only, sticks 1.0, buttons, poses 0x8f), but the room
+draws no controllers and ignores input; avatar loader forced to its "Failed" path (no logged-in user) changed nothing.
+`frame.ovr_trace` can't trace Unity games (P/Invoke dlsym; nothing imports ovr_*). Headless: the VrApi bridge's 30 s
+head-pose deadline ends VR mode without a worn headset (not a game bug).
 **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).
+
+**Cube swapchains (GitHub #107, 2026-10-09):** the Frame's runtime refuses `faceCount=6` swapchains (-2,
+XR_ERROR_RUNTIME_FAILURE); OVRPlugin ignores that ("CreateSwapchain for eye 0: 0x0, 0 stages") and crashes in
+ovrp_EndFrame4 (memset). FrameBridge `cube_standin` (default on, `native/adapter/cube_standin.c`) serves a refused cube
+swapchain as one GL cube-map texture in the app's context (GLES only) and drops its layers. Verified headless with
+Budget Cuts Ultimate (2048² sRGB, 12 mips; runs on at ~70 fps); what the cube layer showed is simply missing.
+**Vivox API 31 (GitHub #101, 2026-10-09):** newer Vivox builds (Green Hell VR) call Android 12 AudioManager
+communication-device methods from `com.vivox.sdk.AudioChangeListener` with no SDK check → NoSuchMethodError on Lepton's
+Android 11. `frame.vivox_audio_route` (analysis `vivox_api31`, ANALYSIS_VERSION 4) makes every such method return at
+once (`Dex.return_early`: return-void / `const/4 v0,0; return v0`; nopping the invoke would leave a move-result the
+verifier rejects). Older Vivox (Eleven Table Tennis, BattleSisters) lacks that code and isn't matched. Verified
+headless: Vivox initialises, 150 s at ~65-70 fps.
+**Multiview programs on flat framebuffers (GitHub #77, Doom3Quest, 2026-10-09, prototype):** Mesa enforces OVR_multiview's
+"program num_views == draw framebuffer views" rule (`draw_validate.c`, the draw is dropped silently); Qualcomm doesn't.
+Doom3Quest compiles every VS with `layout(num_views=2) in;` and draws its HUD/PDA into 2D-texture FBOs → black. Opt-in
+`frame.gl_multiview_fbo` (analysis `gl_multiview_libs`, ANALYSIS_VERSION 6; own-engine GLES only): `native/glmv` =
+`libfpglmv.so` (12 chars = "libGLESv3.so": libdoom3.so's one `.rodata` dlopen string is rewritten in place, its qgl*
+table comes from dlsym on that handle; also first DT_NEEDED for its direct gl*/egl* imports). Such draws use a lazily
+built single-view twin (view 0, uniforms copied per draw); eglMakeCurrent resets the per-thread cache. Host-tested only
+(rewriter on all 19 Doom3Quest shaders + glmv.c against a stand-in GL, `tests/test_gl_multiview_fbo.py`); the host's
+Mesa 23.2 llvmpipe has no OVR_multiview, so no real-driver test yet. Not in the catalog until a headset test.
 **Unresolved (as of 2026-09-28):** Arcsmith (right-eye distortion) and Time Stall (both eyes) — swap, tracking, Valve
 layers, depth, pacing ruled out. Sniper Elite VR (DEVICE LOST), Espire 1 (Mesa GL upload crash), HITMAN 3 (freedreno
 crash): use PC versions.
 
+**Install links / FrameDrop button protocol (2026-10-07, not yet clicked end to end from a browser):** FrameDrop
+(framedropvr.com, a closed-source Windows sideloader) defines "Install with FrameDrop" buttons:
+`https://framedropvr.com/install?manifest=<url>|url=<file>` → that page opens `framedrop://install?…` (1.6 s, else its
+home page); manifest `{"schema":"framedrop.install/v1","name","files":[{"url","sha256"}]}` (name = Steam title; .apk
+or Linux .zip). `deeplink.py` (no Flet) parses framedrop://, frameport:// and the pasted https link, enforces its
+rules (https; http only on loopback; no credentials; no LAN/loopback/link-local IPs, also after DNS and redirects; URL
+ends in a file name), caps manifests at 256 KiB, ignores non-hex sha256 (FrameDrop's own example has a placeholder),
+downloads into `<data>/downloads/<slug>-<hash>/` (OBBs → `obb/` next to the APK, `.part` removed on cancel/mismatch);
+`pipeline.add_from_link` routes APK / Linux / exe and sets `title` + `title_locked` + `link` (a bare file link keeps
+FramePort's title). GUI: `views/link_dialog.py` (always asks first), Add games → "Install from a link…", CLI
+`frameport open-link [--yes --no-install --gui]`. **A `flet build` bundle can't take a URL argument** (the Flutter
+host treats any argv as a developer page URL), so `urlhandler.py` registers a script, not FramePort.exe: Windows
+HKCU `Software\Classes\{framedrop,frameport}` → hidden PowerShell `frameport-link-handler.ps1`; WSL (source runs)
+the same keys → `wsl.exe -d <distro> -e sh frameport-link-handler.sh`; Linux `frameport-links.desktop` +
+`xdg-mime`; macOS unsupported (Apple Events, paste instead). The script drops the link into `<data>/links/*.link`
+and starts FramePort unless `<data>/gui.alive` is < 10 s old (`gui.starting` stops double starts); the GUI's
+`_watch_links` thread touches the heartbeat and opens links (newest window session). Settings → Install links: one
+switch per scheme (`links.framedrop`, `links.frameport`, default on); a scheme another program owns (FrameDrop) is
+only taken with "Use FramePort for these links" (`register([s], force=True)`); off removes only FramePort's own
+registration (`MARK` in the command). Never registered with FRAMEPORT_HOME/FRAMEPORT_NO_LINK_HANDLER (tests,
+screenshots). Same round: files dropped on the Library (`ui/dropped.py`, bundles only like the Files tab), "Add a
+Windows program (.exe)…" (`pipeline.add_windows_exe`: exe in Downloads/home/drive root copied alone into
+`<data>/windows-apps/<slug>/`), patch `device.display_mode` (Automatic / VR / Flat window → `InstallContext.display`,
+`installer.show_window`). FramePort-only manifest extension `"frameport": {"description", "icon"}` (bad values ignored; icon: same URL rules,
+≤2 MiB, Pillow-checked, ≥32 px, saved as PNG in `<data>/downloads/icons/`, shown in the question by asset URL, then
+`sources.apply_custom(pkg, "icon")` unless `.picked` exists; description fills `details.description` only when
+empty). Bare file links get a title guessed from the file name (`title_from_filename`: version/arch dropped, package
+names → last part). Windows test of 0.12.1.dev191 (2026-10-07): a button click opened the dialog; but a click right
+after closing FramePort did nothing (the closed window's heartbeat was < 10 s old) → the handler scripts now wait
+up to 4 s for the link file to be taken before trusting the heartbeat, the window's CLOSE event / atexit delete
+`gui.alive`, and the Windows command runs under `conhost.exe --headless` (plain `-WindowStyle Hidden` flashed a
+console). Screens: `scripts/ui_smoke.py --links --fake-frame --game <pkg>` (tall pages: `--viewport
+1280x7000`; Flutter's popup menu ignores Escape).

+details: Unreal Engine 5 game that uses Meta's Application SpaceWarp (extra motion-vector and depth swapchains). OVRPort's
+  patch_disable_space_warp doesn't reach Unreal Engine 5, so FrameBridge's hide_space_warp hides XR_FB_space_warp and

+  shows no frames for 40-80 s while the game's Sentry SDK (debug mode) logs its breadcrumbs. Valve's VALVE_rpo
+  (render-pass optimizer) Vulkan layer removes the game's fog (owner-verified 2026-10-05; with only VALVE_fdm_injection

+  of a single-sampled depth attachment (VUID-VkSubpassDescription2-flags-04908, -03179), harmless on Quest's driver,

+  game's key map picked the empty Gear VR controls (frame.unreal_quest_keymap keeps the Quest set). Two lightspeed
+  shaders, as the Frame's GL driver (Zink) compiles them, read loop counters and accumulators before setting them
+  and hang the GPU; a Vulkan layer under Zink inserts the stores that zero them (frame.zink_shader_fix, zink_shader_fix;
+  the captured modules are from Lepton 2.8.14 and stop matching if a Frame update changes the driver's output -
+  the layer logs that). OVRPlugin asks for poses at its own clock (pose_time_fix). Unreal's Oculus input animates the
+  thumbs from near-touch, which the Frame never reports (frame.unreal_thumb_touch reads the touches instead; binding
+  the proximity to the touch inputs in FrameBridge didn't reach the game). The Frame's SteamVR runtime

+notes: Steady view with pose_consistency (the judder is gone).
+details: Unity 2022.3 with the Oculus XR Plugin falls back to GLES (Zink) on the Frame, where its single-pass
+  (multiview) rendering drew the right eye wrong (GitHub issue 8); frame.unity_multipass renders each eye in its own
+  pass (OculusSettings.GetStereoRenderingMode + its inlined read in OculusLoader.Initialize). Poses and frame times
+  are consistent, but every frame reaches the runtime one display period late (two passes on Zink) and the game
+  clamps its physics step to 10 ms. The judder came from the game locating its views about three times per frame and
+  getting slightly different poses each time; FrameBridge pose_consistency returns the same views for repeated
+  queries of one display time (proposed in GitHub issue 8). The grey right eye on the loading screen is still open.

+details: Both builds - the game runs (72 fps), but its player body stayed frozen - no head tracking, the controllers stuck to the
+  model, no buttons - although OpenXR input and OVRPlugin's poses were fine. A few seconds after start (when Unity
+  switches XR loaders) OVRPlugin reports the worn headset as not worn (ovrp_GetUserPresent2 -> 0), and BONELAB's
+  Marrow rig only follows the player while Unity's HMD device reports UserPresence (OpenControllerRig checks
+  XRHMD.IsUserPresent every frame). frame.unity_user_presence reports the headset as worn. Build 1.2974 only - it adds Stress
+  Level Zero's graphics plugin (libSLZQuestNative.so), which hooks Unity's Vulkan start-up (vkCreateInstance/
+  vkCreateDevice) and vkCreateSampler; on the Frame its vkCreateInstance wrapper calls an invalid pointer right after
+  OVRPlugin's pre-init instance is destroyed (a jump to 0, into an unloaded library, or a hang). frame.slz_vulkan_hooks
+  switches its two registrations off, so Unity starts Vulkan itself; the plugin's pipeline cache isn't used.

+title: SUPERHOT VR
+status: works
+notes: Quest version. Needs FramePort's launcher from agent 41 (reinstall once) so the game can write its saves.
+details: Unity 2018.4 with built-in Oculus support (GLES). Its eye swapchains (GL_RGBA8, then a 16-bit format) are
+  created as sRGB by the adapter's swapchain_fix. The game creates its cloud save folder with mode 1700 and quits at
+  start when it can't write there ("Something failed to initialize. Quitting!"); the launcher now gives every folder
+  in the game's storage owner and group write permission.

+- **Upstream fixed a bug we work around**: register an `UpstreamFix` (`patches/upstream.py`) in the workaround's

+# 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,

+# FAQ
+
+## How should I lay out a game that has OBB files (an APK plus a data folder)?
+
+Give every game its own folder, put the APK in it, and put the game's data next to the APK in a folder named
+after the game's **package name** (the name the `.obb` files contain, e.g. `com.Armature.VR4`):
+
+```
+Games/                                  ← scan this folder (Add games → Scan a folder)
+├── Resident Evil 4/                    ← one folder per game (any name)
+│   ├── VR4.apk                         ← the APK (any file name)
+│   └── com.Armature.VR4/               ← the data folder: exactly the package name
+│       ├── main.203.com.Armature.VR4.obb
+│       └── patch.203.com.Armature.VR4.obb
+└── Beat Saber/
+    └── com.beatgames.beatsaber.apk     ← games without OBBs: just the APK
+```
+
+- **Data folder name:** the package name (`com.Armature.VR4` above), or `obb`. FramePort uses the first of the two
+  that exists and isn't empty.
+- **Everything in that folder is copied** to the game's `Android/obb/<package>/` on the Frame, subfolders included.
+  So games that ship raw data files instead of `.obb` files work the same way.
+- **One game per folder.** Several APKs in one folder count as one game; FramePort uses the first and keeps the others
+  as alternates.
+- **Scanning:** pick the folder that contains the game folders (`Games/` above) to add them all, or one game's folder
+  to add just that game. FramePort looks up to 5 levels deep.
+- **A single game:** Add games → Add an APK file… works with a lone APK too. Its data is found when the data folder sits next
+  to the APK, named as above.
+
+Not sure of the package name? Look at the OBB file names: `main.<version>.<package name>.obb`. Or add the APK
+first: the game's page shows the package name under **Details**.

+## Where FramePort keeps games (internal storage, microSD)
+- Every game has an **anchor** on internal storage: `~/Applications/quest-frame/<pkg>/` with `launch.sh`,
+  `deployment.json`, `artwork/` and `plays.log`. Steam's shortcut points at the anchor's `launch.sh`, so it never
+  changes when the files move.
+- The game's files (`lepton-app/`, `lepton-data/` = saves, `lepton-shaders/`, `settings.conf`, `launch.log`; PC VR:
+  `game/`, `revive/`, `compatdata/` = Proton prefix; Linux: `app/`) live in `deployment.json["base"]`: the anchor
+  itself on internal storage, or `<mount>/FramePort/<pkg>` on another drive (GitHub #90, agent v63).
+- SteamOS mounts removable drives (microSD) under `/run/media/<user>/<label or uuid>`; the agent's `drives` reads
+  `/proc/mounts` (plus the drives of Steam library folders) and refuses vfat/exfat/ntfs (Lepton's data and Proton
+  prefixes need Unix owners, permissions and symlinks) and read-only mounts. A drive that isn't mounted is an error for
+  new installs (never a silent fallback to internal storage); `list_installed` marks games on it `drive_missing` and
+  their launchers stop with "storage not mounted?".
+- `move` copies with `cp -a` inside `podman unshare` (files Lepton's containers own belong to subordinate user ids),
+  compares file count + bytes, retargets absolute symlinks into the old folder (the LibOVRRT → Revive redirect), points
+  `launch.sh` at the new folder and only then deletes the old copy; on the same filesystem it renames instead.
+  Moving a game whose Lepton data holds absolute paths, or a PC VR prefix, is not yet verified on the device.

   VK_INSTANCE_LAYERS (set `VK_INSTANCE_LAYERS=""` through `device.lepton_env` to test without them).
+  The FDM layer follows each eye's gaze; one-eye jitter in some games (GitHub #69) is fixed per game with
+  `device.foveation`: `fixed` = `FDM_DEBUG=disable_offsets`, `off` = `VK_INSTANCE_LAYERS=""`. Lepton passes `FDM`,
+  `FDM_DEBUG`, `FOVE_LEVEL` and `FDM_SWAPCHAIN_SIZE` through to the container (liblepton/mounting.sh PASSTHROUGH_VARS);
+  the layers are chosen on the host, so setting them inside the game does nothing.
+- How Lepton loads them: `liblepton/vulkan_layers.sh` mounts the chosen layers (only those in the OS image's
+  `/usr/share/guestos/android/vendor/vulkan_layers`) into the app's lib dir and writes their names to Android's
+  `settings global gpu_debug_layers` for `gpu_debug_app` = the game; Android's loader reads that list from GraphicsEnv
+  at each vkCreateInstance and searches the app's lib dir (`/data/app/…/lib/arm64`). A layer bundled in the APK is
+  found there too; FramePort's shader-fix layer (`frame.zink_shader_fix`) adds its own name to GraphicsEnv's list from
+  inside the process (`android::GraphicsEnv::setDebugLayers`, exported by the guest's libgraphicsenv.so, Lepton 3.0.5).

+## Video of the headset view (surveyed 2026-10-05; used by the Live view tab)
+- `steamvr-v4l2cam.service` (user unit, part of gamescope-session.target, `Restart=always`) runs SteamVR's
+  `/opt/steamvr/bin/linuxarm64/v4l2cam --output=99`: it reads the compositor's "Headset View" (IVRHeadsetView) and
+  writes it to a v4l2loopback webcam named **"SteamVR"** (`/dev/video99`, 1920x1080 RGB24, advertised 30 fps, frames
+  arrive at the display rate). Nothing on the Frame reads it by default; idle it costs nothing, read ~0.2 core.
+  It shows what the wearer sees (SteamVR home, Steam's panels; a game's layers are expected but not yet seen in it).
+  Black and ~1 fps (one frame per ~1.0 s) while the headset sleeps (standby): a 30 fps stream then repeats each
+  frame in bursts, which looks like a stall in a player. Its size follows SteamVR's headset view (v4l2cam has no size
+  option), so the live view only scales down (360p/480p/720p/1080p) or sends it as is ("full").
+- Sound: `pactl get-default-sink` (`alsa_loopback_device.stereo.alsa_output.platform-sound.HiFi__Speaker__sink`) and its
+  `.monitor` source carry what the headset plays; the Frame's ffmpeg has the `pulse` input and `aac`. Timestamps: pulse
+  uses the wall clock, v4l2 CLOCK_MONOTONIC → `-ts mono2abs` on the v4l2 input. Don't force
+  `-use_wallclock_as_timestamps` on the pulse input: it stamped bursts of AAC packets with one time.
+- Steam's own game recording / Remote Play / broadcast capture the **gamescope** PipeWire node (`CDesktopCapturePipeWire:
+  ... node path: gamescope`): with gamescope's `--backend openvr` that's only the flat Steam UI, not VR. Steam's arm64
+  `libvideo.so` encodes with x264 (vaapi/nvenc paths don't apply). No cast/spectator feature for the Frame's own VR view
+  exists in Steam's UI; the SteamVR web server (27062) has no mirror route.
+- Encoding: the Qualcomm encoder (`/dev/video23` qcom-iris-encoder, V4L2 M2M) doesn't work with the stock tools (ffmpeg
+  `h264_v4l2m2m` hangs, gst `v4l2h264enc` not-negotiated). ffmpeg + libx264 works: FramePort's live view
+  (`install/livestream.py`: `fps=30` before the scale, ultrafast/zerolatency, 3 threads, nice 10, fragmented MP4 on
+  stdout, + AAC 128k) measured 0.34 core at 720p / 0.56 at 1080p with a quiet picture (video only); expect ~1-1.4
+  cores with a busy scene. That is now only the fallback.
+- Hardware encoding (2026-10-07): the iris encoder works when driven directly through the V4L2 stateful encoder
+  interface. That is FramePort's `fp_venc` (`native/venc`, spec + every measured value in `native/venc/SPEC.md`).
+  Facts:
+  - Device: `/dev/video23` (`/dev/video-enc0` links to it), driver `iris_driver`, M2M multiplanar.
+  - Formats: input NV12/NV21/AB24(RGBA)/QC24/Q08C; output H264/HEVC; sizes 128..8192.
+  - NV12 layout (S_FMT answers):
+    - stride is a multiple of 128;
+    - the returned height is padded to a multiple of 32;
+    - CbCr starts at stride × padded height;
+    - sizeimage is rounded up to 4 KiB;
+    - the default crop is the requested size.
+  - Controls: CBR, FORCE_KEY_FRAME, PREPEND_SPSPPS_TO_IDR, HEADER_MODE joined, FRAME_SKIP_MODE, H.264 profiles
+    Baseline..Constrained High, levels up to 6.0.
+  - The `steamos` user can open it (group video).
+  - The panel's current refresh rate can be read without privileges through DRM: `/dev/dri/card0` is mode 0666, and
+    GETCRTC reports e.g. `2*2160x2160_96` (clock 1402720 kHz / 4448 × 3285 = 96 Hz) even while the headset sleeps.
+    The panel offers 72/80/90/96/108/120/144 Hz.
+  - `/dev/video99` (v4l2loopback) has `max_buffers=2`: a reader asking for more gets 2.
+  - Mid-stream keyframe requests (FORCE_KEY_FRAME) take effect on the next frame, and the GOP restarts from there.
+  - Measured 2026-10-07 with the headset asleep (still picture):
+    - `fp_venc` alone at 32/36 fps: 1% of a core at 1080p, 2.5% at 720p.
+    - Live view end to end: `fp_venc` 2.6% + ffmpeg 8.4% (AAC encoding + muxing).
+  - Conversion cost per new picture (self-test, NEON, 2026-10-07):
+    - 1080p (no scaling): 0.6–1.0 ms.
+    - 720p (exact 3:2 fast path): 1.3–1.65 ms, down from 5.6 ms with the generic box loop (~11 ms at idle clocks).
+    - 360p (3:1 fast path): 0.7 ms.
+    - 480p: 2.8 ms; its 852-px width doesn't repeat cleanly, so it uses the generic path.
+    - At 36 fps with live content that is roughly 2–6% of a core.
+  - ffmpeg with raw H.264 on a pipe:
+    - `-framerate` is ignored.
+    - `-fflags nobuffer` loses the first seconds of tiny frames.
+    - Numbering frames from 0 (`setts`) with no input timestamps holds all output ~7 s next to pulse's audio.
+    - Arrival stamps alone (`-use_wallclock_as_timestamps 1`) bunch frames that are read together: gaps of 0–10 ms
+      and 45+ ms, seen in the headset test as dropped frames.
+    - What works: `-probesize 32 -analyzeduration 0 -use_wallclock_as_timestamps 1` on the input (ffmpeg reads it in
+      step with the audio), then `-bsf:v setts=ts=N*(1/fps)/TB` on the output (exactly even frames; audio still
+      0–N s alongside), plus `frag_keyframe` so that a requested keyframe starts a fragment.
+    - With sound, ffmpeg paces its inputs against each other and pulse's audio arrives later than the wall clock
+      (more while something plays). The video input then counts as ahead, and ffmpeg stops reading it for up to
+      0.7 s, so the writer blocks. That was the cause of 1080p dropping frames: busy 1080p replayed with sound took
+      34–47 s for 20 s of video. Video alone was fine; `nice`, `-raw_packet_size` and the input queue size didn't
+      matter. Shifting the video input back fixes it, but too far makes ffmpeg hold the video for interleaving and
+      release it in clumps: -1 s gave output gaps of up to 550 ms, a longer and stuttering delay in the browser.
+      -0.25 s is the measured sweet spot (no stalled writes at busy 1080p with sound, steady 50–150 ms output; -0.5 s
+      already clumps). Output audio/video spans stay equal because setts sets the output times.
+    - Browser delay (headless Chromium, 720p, 2026-10-07): muted about 0.2–0.35 s behind the newest data; with
+      sound about 1 s. Chrome keeps about 0.6 s of audio ahead and stalls below that, whatever the player does:
+      1.1× catch-up gave 8 stalls per 30 s, no speed-up 1–2, same average lag; 50 ms fragments didn't help. So the
+      player doesn't speed up while sound is on.
+  - Quality (owner's headset test, 2026-10-07): 3 Mbit/s CBR at 720p36 showed heavy compression artifacts. The
+    hardware path now uses VBR with a 1.5× peak (the encoder accepts BITRATE_MODE VBR + BITRATE_PEAK) and higher
+    targets: 360p 1.5, 480p 2.5, 720p 5, 1080p 8, Full 10 Mbit/s. The x264 fallback keeps its rates.

+### With a USB cable
+
+For networks that block the setup (guest Wi-Fi, firewalls, discovery not working), and for faster uploads:
+
+1. On the Frame, turn on **Developer Mode** (Settings → System → Developer Mode). The Frame's USB network only exists
+   in Developer Mode.
+2. Connect the Frame's USB-C port to the computer.
+3. In FramePort: **Steam Frame → Set up with a USB cable**. FramePort detects the cable and shows the setup command,
+   which reaches the computer over the cable. Already set up? It connects over the cable right away.
+
+The cable needs no driver on Windows 10/11, macOS or Linux, and the computer gets an address from the Frame
+automatically. Uploads use the cable whenever it's plugged in (about 37 MB/s, ~3× typical Wi-Fi), even when FramePort
+connected over Wi-Fi. Unplug it any time: FramePort finds the Frame on Wi-Fi again by itself.
+
 ### Firewalls
 
 If the setup command only says "timed out", a firewall on your computer blocks the Frame; the setup page
 says which after about 45 seconds. Details per system: [FRAME_SETUP.md](FRAME_SETUP.md#network-and-firewalls).
 
+## Running FramePort on the Frame (experimental)
+
+FramePort can run on the Steam Frame itself, without a PC: in **Desktop Mode**, download
+`FramePort-linux-arm64.tar.gz`, unpack it (`tar xzf FramePort-linux-arm64.tar.gz`) and start `FramePort/FramePort`.
+Turn on **Developer Mode** first (Steam → Settings → System); FramePort then manages "This Frame" directly, with
+no pairing. Games are added to the Steam library when you go back to **Gaming Mode** (Steam has to restart for it,
+which would end Desktop Mode). This is new: please report anything odd with **Report a problem**.

+  wrong (a phone app shows nothing in the headset, or a VR app opens as a flat window), choose **VR** or **Flat
+  window** under **Show as VR or as a flat window** in the game's **Customize** section, then **Update on Frame**.
+- **Add games → Add a Windows program (.exe)…** adds a single Windows program; the Frame runs it through Proton (as a
+  window unless it is a VR game). A program sitting in Downloads, the home folder or a drive root is copied on its
+  own first, so the install doesn't upload everything next to it.
+- In the packaged app you can also **drag files onto the Library**: APKs, Linux apps (AppImage, `.zip`/`.tar.gz`),
+  Windows programs (`.exe`), folders, or a FrameDrop manifest (`.json`).
+
+### Install links ("Install with FrameDrop" buttons)
+
+Some developers put an **Install with FrameDrop** button on their site (the one-click protocol of the FrameDrop
+sideloader, documented at framedropvr.com/docs). FramePort understands the same links:
+
+- **Clicking a button** opens FramePort (or the window that's already open) on Windows and Linux. FramePort shows
+  the title, the files, their size and whether a checksum is given, and asks before it downloads anything. Then it
+  downloads the build, adds it to your library and starts the usual install on the Frame. If no Frame is connected,
+  the game is added now and installs once the Frame is back.
+- **Add games → Install from a link…** takes the button's address (right-click → Copy link), a `framedrop://` or
+  `frameport://` link, a manifest (`.json`) or a direct link to an APK, a Linux build or a Windows program. Use it on
+  macOS, where web pages can't hand links to FramePort yet.
+- **Settings → Install links** has one switch for `framedrop://` links (the buttons) and one for FramePort's own
+  `frameport://` links. Both are on by default. If FrameDrop is installed too and already opens `framedrop://`
+  links, FramePort leaves them to it; **Use FramePort for these links** takes them over (turn the switch off to give
+  them back).
+- **For developers:** a FrameDrop manifest works as it is
+  (`{"schema": "framedrop.install/v1", "name": "…", "files": [{"url": "https://…", "sha256": "…"}]}`). FramePort
+  also reads an optional `"frameport": {"description": "…", "icon": "https://….png"}` object (FrameDrop ignores
+  it): the install question then shows the icon and description, and they become the game's icon and "About this
+  game" text when no store has them. Without a manifest (a bare file link) FramePort guesses the title from the
+  file name and replaces it with the app's own name once it's downloaded.
+- Only `https://` links to public servers are used (plain `http://` only on this PC, for testing); links with a
+  user name or password, or pointing into your local network, are refused. Only install from sites you trust.

+unchanged and adds it to the Frame's Steam library, tagged "Linux app on Frame"; Play, launch tests and Uninstall

+
+- **x86_64 builds** run through **FEX**, Valve's x86 translator, with the x86 system libraries SteamOS ships for it
+  (the way Steam on the Frame runs x86 Linux games). The first install of one installs FEX on the Frame (Steam
+  restarts once and downloads it, a few MB). They run slower than arm64 builds: when an app offers both, FramePort picks the arm64 one. The game
+  page shows which CPU a build is for.
+- The app must bring the libraries SteamOS doesn't have (checked for arm64 builds; x86_64 builds use FEX's x86
+  system, which has glibc and Mesa, and aren't checked ahead). If some are missing, the install reports them and the game
+  page lists them: look for a build that includes them.
+- **Desktop Mode:** Linux apps also appear in Desktop Mode's application menu and as an icon on its desktop. Some
+  apps work better there, with a mouse and keyboard, than in Gaming Mode (where Steam Input turns the controllers into

A larger prediction is capped by OVRPlugin (~0.07 s) | `frame.unity_oculus_check` revision 5 holds the physics-step update back: both steps read the render update's display-time poses |
+| OVRPlugin game: the hands lag behind the controllers (also with `ovrp_hold_physics` on or off; rendering fine), e.g. BattleSisters | OVRPlugin passes its monotonic-clock "now" on as the OpenXR time (OVRPort's dispatcher converts XR_KHR_convert_timespec_time 1:1: the Frame's runtime lacks it, and FrameBridge's emulation is never asked), but the Frame's XrTime runs ahead of CLOCK_MONOTONIC (2.56 s on SteamOS 0.4.5): with `pose_debug=1` the hand spaces show `time - predicted display time -2564 ms`; BattleSisters also asks for its head at XrTime 0.1 s every frame | `adapter.pose_time_fix` (FrameBridge, suggested for Unity built-in OVRPlugin games): a located time nearer the monotonic clock than XrTime's "now" is moved by the clock offset measured at xrWaitFrame, one more than 0.5 s before the display time goes to "now" (log `pose_time_fix: …`; `pose_debug=1` counts both per 5 s). Once a build has this FrameBridge it is toggled in settings.conf (no rebuild) The offset is the largest of the last ~2 s of xrWaitFrame samples (hitches made single samples dip by up to 2.5 s and pushed fixed times into the future); far-past requests get the frame's display time. Headless survey of 54 games (2026-10-09): no head/view request on the monotonic clock in any other game; UE4 OVRPlugin 1.89 games (Robo Recall, Vader, Phantom, Time Stall) and The Room VR ask for head/views at XrTime ≈ 0 every frame, which works today; hands only show in the headset. Suggested for Unity built-in Oculus games only. A time equal (±1 ms) to one of the last 6 predicted display times is never moved, and monotonic times are only told apart when the clocks are more than 4 display periods apart and the time is clearly nearer the monotonic "now" (GitHub #49: on a Frame with XrTime only ~68 ms ahead, a display-time request after a hitch was moved +67.7 ms) |

+| Game crashes at start: `java.lang.NoSuchMethodError: No virtual method getAvailableCommunicationDevices()… in class Landroid/media/AudioManager` at `com.vivox.sdk.AudioChangeListener.checkAudioRouteAndApplyChanges` (e.g. Green Hell VR, GitHub #101); triage `vivox-api31` | Newer Vivox (voice chat) builds call Android 12 audio-routing methods without a version check; Lepton is Android 11. Older Vivox builds (Eleven Table Tennis, BattleSisters) don't have that code | `frame.vivox_audio_route` (suggested by analysis `vivox_api31`): every AudioChangeListener method that calls one of them returns at once (`Dex.return_early`: return-void / `const/4 v0, 0; return v0`, in place); voice chat keeps the default audio route |
+| Controllers do nothing (e.g. stuck on a setup screen); log: `xrSuggestInteractionProfileBindings … XR_ERROR_PATH_UNSUPPORTED` | the game only suggests bindings for Meta's newer profiles (Touch Plus / Touch Pro); the Frame's Android runtime knows `oculus/touch_controller`, not those | adapter `profile_remap` (default on): the bindings are suggested again for Touch (log: `controller profile … -> oculus/touch_controller`) |
+| Some buttons do nothing or the wrong thing (e.g. a Quest game's X/Y on the Frame's left controller) | the game binds only Quest Touch and SteamVR maps Touch onto the Frame controllers with its own remap (Touch left X/Y land on the d-pad, right X and Y repeat B), or the runtime rejected a profile or an input call | turn on adapter `input_diag` (diagnostics, off by default; `frameport settings <pkg> input_diag=1`) and look for `input_diag:` lines: `bindings: <profile> accepted` or `unsupported: interaction profile <profile> -> <result>` with the rejected paths, `bindings: /user/hand/<hand> uses <profile>`, `unsupported: function <name>`, `unsupported: xrCreateAction -> <result> (<action>)` |

Switching to the recommended level.` (e.g. Lucky's Tale) | Meta's OVRManager (`useRecommendedMSAALevel`) turns 4x MSAA on at runtime, past QualitySettings; multisampled render-to-texture on GLES/Zink hangs the GPU | `frame.unity_runtime_msaa_off` (Cpp2IL: `OVRDisplay.get_recommendedMSAALevel` → 0) |
+| Unity game: one eye shows only effects or grey, the other is fine (e.g. I Am Cat, Oculus XR Plugin on GLES) | the game's single-pass multiview rendering goes wrong for array slice 1 (the adapter submits both slices correctly) | `frame.unity_multipass` (Cpp2IL: `OculusSettings.GetStereoRenderingMode` → MultiPass); `swap_eyes=1` tells whether the game or the adapter is at fault |

+| Unreal game (ILMxLAB, e.g. Vader Immortal) plays its intro, then stays on its loading card (portrait + progress bar) at 72 fps and ignores input (GitHub #49) | the menu waits for `UVRUtils::GetQuestShaderPrecompilePercent()` to reach 100 %; the precompile only starts when `IsRunningOnSantaCruz()` (a Quest), the other branch returns 0.0 | `frame.unreal_quest_precompile` (non-Quest branch returns 1.0; found by Klownicle); suggested when the engine exports that function (analysis `unreal_quest_gates`) |
 
 ## Picture problems (headset on)
 | Symptom | Cause | Fix |
 |---|---|---|
+| Unreal game (ILMxLAB, e.g. Vader Immortal): controllers track but grip/trigger do nothing, grabbing never works (Unreal's own input values move, the game's stay 0) | `URPOCKeyMapManagerComponent` picks the Quest or the Gear VR key set by `IsRunningOnSantaCruz()`; on the Frame it takes Gear VR, empty in a Quest build | `frame.unreal_quest_keymap` (the Oculus case keeps the Quest set, for action and axis mappings; found by Klownicle, GitHub #49) |
+| The hands' thumbs never move when you touch the thumbstick or buttons (Unreal `ThumbUp` stays 1, e.g. Vader Immortal) | OVRPlugin reports thumb proximity from XR_FB_touch_controller_proximity, which the Frame's runtime lacks; OVRPort's loader offers it anyway and the proximity actions never get a binding | adapter `proximity_emul=1` (thumb proximity from the touch inputs: thumbstick, face buttons, thumb rest; 2 = also the index finger from trigger touch); log `proximity_emul: finger proximity bound to touch`. **For UE4 Oculus games this didn't animate the thumbs** (Vader, GitHub #49): use `frame.unreal_thumb_touch` (found by Klownicle): `OculusInput::FOculusInput::SendControllerEvents` computes ThumbUp from NearTouches (masks 0x2/0x8); the patch makes it read Touches (the slot 4 bytes before) with masks 0x0f00 (X/Y/stick/thumb rest) / 0x000f (A/B/stick/thumb rest), keeping the inversion; three instructions, matched exactly (build note `OculusInput ThumbUp: from the capacitive touches`). Matches Vader Immortal Ep. I, Robo Recall, Phantom: Covert Ops, Time Stall, Star Wars: Tales from the Galaxy's Edge; newer UE4 builds (e.g. Asgard's Wrath 2, RE4, In Death) compile it differently (shared mask registers) and aren't matched |
+| OpenGL ES game: the GPU hangs at one effect (freeze/exit, compositor watchdog, e.g. Vader Immortal's lightspeed jump) | a shader (as Zink compiles it) reads loop counters/accumulators before setting them | capture the SPIR-V (adapter `zink_shader_dump=1` writes every module to `files/fp_spirv/`, or a GPU capture), then a `zink_shader_fix` entry (same format as `vk_shader_fix`) + `frame.zink_shader_fix` (Vulkan layer under Zink, activated through GraphicsEnv's debug layer list); log `shader fix layer: fixed shader module N`; triage `zink-shader-fix-mismatch` when a Frame update changed the driver's output |
 | 2D Android app: Steam says it's running but nothing shows | Lepton runs apps headless unless the app folder has `lepton-show-flatscreen` | FramePort adds it for apps without VR (agent v28+); reinstall apps installed before |
+| A phone/tablet app shows nothing in the headset, or a VR app opens as a flat window | FramePort's VR/2D guess (`vr_kind`) is wrong for this app | patch `device.display_mode` → **Flat window** or **VR** (Customize → "Show as VR or as a flat window"), then Update on Frame |
+| "Install with FrameDrop" button opens FrameDrop (or nothing) instead of FramePort | another program owns `framedrop://`, or the switch is off, or macOS (Flet can't receive links there) | Settings → Install links → **Use FramePort for these links**; else Add games → Install from a link… (paste the button's address) |
 | 2D Android app: back/home/recents buttons cover the app's own buttons | Android's navigation bar | patch `device.hide_navbar` (on by default for apps without VR) sets `qemu.hw.mainkeys=1`; reinstall to apply |

+| Own GLES engine (OpenXR, not VrApi): eye view fine, but HUD / menu / PDA panels black (e.g. Doom3Quest, GitHub #77; no error in the log) | every shader declares `layout(num_views=2) in;`, also the ones drawn into the engine's single-layer offscreen framebuffers (2D textures/renderbuffers); OVR_multiview makes such draws INVALID_OPERATION and Mesa drops them (`draw_validate.c`), Quest's driver doesn't | `frame.gl_multiview_fbo` (opt-in, experimental: `libfpglmv.so` interposes GLES and draws those cases with a single-view twin of the program; logs `GLMV: twin built: program N -> M`, per-5-s `single-view draws` counters; `gl_mv_debug=1` adds glGetError checks; triage `gl-multiview-twin-failed`). Alternative: the game's own fix (two-layer multiview pool, Xandrix's patch in #77) |

+| Picture drifts out of sync with the sound | the hardware path relies on one H.264 frame per fps slot (ffmpeg `-framerate`); `fp_venc: stats … skipped=` > 0 on stderr means slots were skipped | see the stats line (every 10 s); a stopped/suspended Frame skips slots on purpose |

 ## Debugging techniques that worked
 - A user's problem report: `frameport diag inspect <FramePort-diag-*.zip>` re-triages its launch log with the current
   signatures; the zip has the recipe, analysis, ELF/PE imports, Frame logs and versions (docs/DIAGNOSTICS.md).
 - Read `<base>/launch.log` (logcat mirror). Filter the game's pid: `Start proc <pid>:<package>`.
+- **Monitor tab** (GUI, while a game runs): fps from FrameBridge's pacing lines next to GPU busy %, the hottest
+  sensor, memory pressure and per-process CPU/GPU/memory. A memory runaway (Lucky's Tale, Vader Immortal) shows as
+  rising memory + "waiting" before the OOM kill; a GPU-bound game as GPU near 100 % with fps under target; heat as the
+  temperature tile turning amber/red. Sources and costs: FRAME_RUNTIME.md "Monitoring sources".
 - The adapter logs as `FrameBridge` (settings, xrCreateInstance result, swapchain retries, pacing fps).
 - For GLES/GLAD engines, wrap `eglGetProcAddress` to see shader compile errors (build the shim with `-DGLSHIM_TRACE`
   for per-FBO draw counts and draw-call errors; the bridge has `-DOVP_GL_DIAG` for eye-image readback).
 - Anything visual needs one headset session per iteration — batch hypotheses into each build.
+- Headless launch tests never get focus: they prove startup, not play. Crashes right after FOCUSED (Myst), focus
+  dips and judder only show up in a headset session: ask for one, then `frameport diag collect <pkg>` (it contains
+  the headset sessions too, plus this boot's kernel log).
+- Which library a stale pointer belonged to: turn on the Android linker's log for one run by adding
+  `debug.ld.app.<pkg>=dlopen` as an extra line of `LEPTON_GFXRECON_FP_PROPS` (first line `0`) in the game's
+  launch.sh on the Frame (back it up, restore it after) and look for `dlclose: unloading "…"`.
+- Memory runaways / busy loops: `perf` works as steamos (`perf_event_paranoid` 2, user space only; `ptrace_scope` 1
+  blocks eu-stack/gdb/debuggerd). `perf record -p <pid> -e page-faults -c 64 --call-graph fp` names the thread
+  touching new memory (`perf script -F comm,tid,ip,dso`); `-t <tid> -F 499` samples one thread. Map IL2CPP
+  addresses with a full Cpp2IL diffable-cs dump (method `Offset` = address − the r-xp mapping of libil2cpp.so).
+  Sample memory per mapping name from `/proc/<pid>/smaps` (`[anon:libc_malloc]` = native heap).
+- Hangs (every thread asleep): backtraces of all threads with gdb. Root inside the Lepton container may ptrace the
+  game (the host's `ptrace_scope` 1 doesn't apply there) and the guest has `gdbserver64`; `debuggerd -b` fails (no
+  tombstoned). Copy every mapped library to a local sysroot (`podman exec <container> cat /proc/<pid>/maps`, then
+  `tar -chf - -T <list>` through `podman exec -i`; the app's own libs from the installed `lepton-app/game.apk` at their
+  `/data/app/…/lib/arm64` path), then on the PC: `gdb -batch -ex "set sysroot <dir>" -ex "target remote | ssh
+  steamos@<frame> podman exec -i lepton-steamlaunch-<appid> gdbserver64 - --attach <pid in the container>" -ex
+  "thread apply all bt 25" -ex detach` (`set sysroot target:` makes gdbserver assert in linux_mntns_readlink).
+  `/proc/<pid>/task/*/syscall` (read inside the container) shows each thread's syscall and pc without a debugger.
+- Unity catches native crashes itself: no debuggerd backtrace in Lepton's logcat-crash.log, but a
+  `tombstone_00` in the game's `Android/data/<pkg>/files/` with the memory map (map pc/lr/registers to libraries).
+- Focus losses: the game sees FOCUSED→VISIBLE→SYNCHRONIZED (OVRPlugin `[XR_SESSION]`, FrameBridge `focus_hold:`
+  lines); the cause is on the host: `~/.local/share/Steam/logs/vrserver.txt` (`HMD off/on`, `entering standby`,
+  `SystemButtonDown` in vrclient_vrcompositor.txt) and XRService (`[UserPresence]`, `IMUFallback`). Compare the times
+  (Lepton logs UTC, host logs local time).
+- A Unity getter patch that changes nothing: the compiler may have inlined it (no `BL` to its address in
+  libil2cpp.so) — patch the field read in the caller (`Il2cppReturnPatch.field_loads`).
+- Fixes found by users count: a reporter's shader capture (VR4) became the `vk_shader_fix` recipe data (match by size
+  + SHA-256, insert words); verify on the device that the log shows the module being fixed.
+- Don't install or test on the Frame while the owner is playing: adding a library entry restarts Steam (FramePort
+  now skips the restart when the shortcut is unchanged and waits while a game runs), and a launch test starts a game.
+- Catalog YAML: a `: ` inside an unquoted value breaks the file and the loader skipped it silently (the game vanished
+  from the list); `tests/test_catalog_files.py` now catches it.
 - Keep the known-good APK and roll back if a change regresses (`PATCHED/_known-good-*`).

This library becomes the loader's first DT_NEEDED; the loader's own exports of the 31 functions it defines are made STB_LOCAL in `.dynsym` (`elf.hide_exports`, nothing moves), so symbol lookups reach the library first. It serves `<tag>.lang` files found in the game's OBB / app files (`$FRAMEPORT_LANGPACK_DIRS` overrides the search path) through `ovr_LanguagePack_*`, `ovr_AssetFile_GetList` (the loader's list + the packs) and `ovr_AssetFile_StatusById`; its own message queue is merged into `ovr_PopMessage`, and every handle that is not ours (an address-range check) goes to the loader's original function, whose address is read at run time from the loader's in-memory `.dynsym`. With patch `frame.asset_files` (marker byte `@FPASSETS@`, or env `FRAMEPORT_ASSET_FILES=1`) it also lists the data's `*.pak` content files as installed `default` asset files and answers `ovr_AssetFile_DownloadById` for them at once (a completed `DownloadUpdate`, then the result with the path).

The engine library gets it as first DT_NEEDED (direct `gl*` imports) and its `dlopen("libGLESv3.so")` string is rewritten to `libfpglmv.so` (same length; its `qgl*` dlsym table); linked `--no-as-needed` to libGLESv3 so dlsym on its handle finds everything it doesn't wrap. It records stage sources at glLinkProgram, caches the draw framebuffer's color-attachment view count per bind, and when a multiview program draws into a 0-view framebuffer it binds a lazily built twin (`glmv_rewrite.h`: num_views layout blanked, `gl_ViewID_OVR` -> `(0u)`; attribute locations + uniform block bindings copied, default-block uniforms copied before every such draw with a shadow to skip unchanged ones), draws, rebinds the original. Logcat tag `GLMV`; `gl_mv_debug=1`. The rewriter is host-tested on Doom3Quest's 19 shaders (`tests/test_gl_multiview_fbo.py`); untested on the device. |
+| `zinkfix/` | `arm64-v8a/libVkLayer_fp_shaderfix.so` | Shader-fix Vulkan layer `VK_LAYER_FP_shader_fix` for OpenGL ES games (patch `frame.zink_shader_fix`): sits between Zink (Mesa's GL on Vulkan) and the driver and inserts the words of `zink_shader_fix` (same format as the Vulkan shim's `vk_shader_fix`: size + SHA-256 match) into SPIR-V modules; `zink_shader_dump=1` writes every distinct module to `files/fp_spirv/`. The engine library loads it first (DT_NEEDED); its constructor puts the layer in front of Android's GraphicsEnv debug layer list (private Android 11 `getDebugLayers`/`setDebugLayers`, found through libvulkan.so's dependencies) before EGL starts, so the loader picks it up from the app's lib dir. Exports only the enumeration functions and `VK_LAYER_FP_shader_fixGet*ProcAddr` (never plain `vk*` entry points). Vader Immortal's lightspeed shaders (Klownicle, GitHub #49). |
 | `xrlayer/` | `linux-arm64/libxr_frameport_timefix.so` + `XR_APILAYER_FRAMEPORT_timefix.json` | OpenXR API layer for Windows PC VR games under Proton on the Frame (glibc aarch64, built freestanding with the NDK's clang), on by default (patch `pcvr.xr_timefix`). Retries `xrCreateInstance` as an OpenXR 1.0 app when the runtime rejects 1.1 (the Frame's SteamVR runtime does, and Proton 11's VR helper asks for 1.1). Also emulates `xrConvertTimespecTimeToTimeKHR`/`xrConvertTimeToTimespecTimeKHR` if the runtime refuses them (the Frame's Android runtime does; its Linux runtime, used by Proton, supports them as of 2026-09-29 — so this part is only a fallback; Proton's wineopenxr needs them for `XR_KHR_win32_convert_performance_counter_time`, which Revive requires) with the adapter's xrWaitFrame-calibrated offset, and drops the extension from xrCreateInstance if the runtime rejects it. Enabled per game by the Proton launch.sh (`XR_API_LAYER_PATH`, `XR_ENABLE_API_LAYERS`). `tests/test_xrlayer.py` builds it for x86_64 and drives it via ctypes. |
 | `oculushmd/` | `win-x64/fp_oculushmd.exe` | PC VR counterpart of overport's `patch_oculus_unreal` (patch `pcvr.oculus_unreal`, default for Unreal Rift games on the Frame). 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). |
 | `xrshim/` | `arm64-v8a/libframe_xrshim.so` | FrameBridge extension shim, only in builds with `controller_models=1`. overport's dispatcher (`libopenxr_loader.so`) answers `xrGetInstanceProcAddr` from a fixed table and refuses everything else (`overportOXR: Unknown proc addr: xrLoadRenderModelFB`), so the adapter never sees XR_FB_render_model lookups. Meta's OVRPlugin gets the function with `dlopen("libopenxr_loader.so")` + `dlsym`, so FramePort rewrites that `.rodata` string in `libOVRPlugin.so` (same length, in place) to `libframe_xrshim.so`. The shim returns the adapter's emulated functions (`framebridge_extension_proc`) and forwards every other name to overport. A DT_NEEDED interposer does not work here (dlsym on a handle searches that library first); tried and dropped. |
+| `venc/` | `linux-arm64-bin/fp_venc` | Hardware H.264 encoder for the live view, run on the Frame (spec: `venc/SPEC.md`). Reads SteamVR's "headset view" webcam (v4l2loopback `/dev/video99`, RGB24), box-scales and converts it to NV12 (BT.709 limited range; `convert.c`, NEON with a bit-identical scalar reference, also built for x86_64 by the host test), and feeds the SoC's V4L2 stateful encoder (`dev-encoder.rst`, Qualcomm iris `/dev/video-enc0`): CBR, no B-frames, SPS/PPS on every IDR, one frame per slot of a fixed grid (fps = a divisor of the panel refresh read through DRM KMS, default cap 45), Annex B on stdout. stdin `k` = keyframe, `q`/EOF = drain and stop; `--probe` prints the setup as JSON, `--selftest` compares NEON and scalar output. Fully static and freestanding (raw syscalls, own `_start`; only the NDK's kernel UAPI headers, staged in `.cache/uapi-arm64`), byte-reproducible. Lives in `linux-arm64-bin/` because `linux-arm64/` is uploaded whole as the OpenXR layer. |
 | `java-stubs/` | `dex/oculusos-stubs.dex` | No-op `com.oculus.os.AnalyticsEvent` / `UnifiedTelemetryLogger` for native code that looks them up. |
