Notes: the jni build override and re-tagging a failed release build

- Sound: the default output's pulse monitor (what the headset plays) as AAC in the same fMP4; the
  player starts muted (browser autoplay rules) with a Sound on button. Video timestamps go to the
  wall clock (-ts mono2abs) instead of forcing it on the pulse input, which gave bursts of AAC packets
  one shared timestamp; aresample=async=1 keeps the sound continuous.
- Late viewers start at a keyframe of the video track (audio samples are all sync).
- Qualities 360p/480p/720p/1080p scale down only; 'full' sends SteamVR's headset view at its own
  size (1920x1080 today; v4l2cam has no size option, so 2K/4K would only upscale).
- Player keeps a 0.3 s cushion and catches up at 1.1x; it seeks only when >2 s behind (seeking to the
  very edge starved playback).

+**Setup / pairing (2026-10-02, verified on the device):** Developer Mode = `"DevModeEnabled"` in
+`~/.local/share/Steam/config/config.vdf` (InstallConfigStore/developer), applied by Valve's
+`/usr/bin/steamos-polkit-helpers/steamos-devkit-mode --enable|--disable` (polkit allow_any: no password; enables/
+disables sshd, xrdp, steamos-devkit-service, debug port forwards; sentinel `/etc/steamos-devkit-enabled`). Steam
+re-asserts the config value at every start and rewrites config.vdf on exit → stop Steam, edit, helper, start.
+**Desktop Mode is a nested Plasma inside steam.service** (own XDG_RUNTIME_DIR `/run/user/1000/nested_plasma` + private
+D-Bus): `systemd-run --user` from Konsole fails ("Failed to connect to user scope bus") unless XDG_RUNTIME_DIR/
+DBUS_SESSION_BUS_ADDRESS point at `/run/user/$UID`, and stopping Steam ends the desktop and everything started in
+it → bootstrap.sh runs the Dev Mode job + Lepton request + `/paired` as a user unit (log `~/.cache/frameport-setup.log`);
+no sudo/password anywhere (verified: naive Frame → connected, password never set). Valve's devkit pairing (fallback,

+while Steam is in pairing mode (Settings → Developer → Pair new host), else 403 at once; approve hook waits 30 s.
+The Frame runs firewalld (22 and 32000 open). PC side: the setup server needs inbound TCP 8765–8767 — WSL's Hyper-V
+firewall blocks it silently (`DefaultInboundAction Block`): `pairing.ensure_reachable` adds a temporary rule via one
+UAC prompt, removed when the server stops (flag file in %TEMP%, max 35 min); hints per OS after 45 s without a request
+(`pairing.firewall_hint`). Flet 1.0 patches aren't thread-safe → `app.serialize_flet_updates()` (a dialog shown while a

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). Send files: `install/files.py`, `frameport frame send|storage`, GUI Frame → Send files.
+**Companion apps / intents (2026-10-03, tested with Stremio + 4XVR):** a second APK can be installed into a running
+Lepton container (`podman exec -i lepton-steamlaunch-<appid> pm install -g -S <size> < apk`) and runs there, VR
+included (4XVR in Stremio's flatscreen container: FrameBridge 72 fps, settings via LEPTON_ENV_FRAMEBRIDGE_CONFIG). But
+Lepton's services.jar (`ActivityStarter.execute`) intercepts **every** `android.intent.action.VIEW` with data (any
+scheme, explicit component or not, no property to disable): it writes `steam://openurl/<uri>` to `/lepton/steam.pipe`
+(= the host Steam client's `~/.steam/steam.pipe`) and starts nothing. So "open in external player" hand-offs (Stremio
+→ 4XVR) can't work inside Lepton; don't retry without Valve changing it. Lepton installs exactly one `*.apk` per app
+folder (two break `get_apk_path`).
+**Text input (2026-10-03, verified in the headset with Stremio VR):** Lepton's Android has no IME (`ime list` empty)
+and runs VR apps headless (`lepton.headless=true`): no Android window has input focus (`dumpsys input` FocusedWindows
+empty), so neither `input text`, a USB keyboard nor Steam's keyboard reach the app. `lepton-show-flatscreen` on a VR
+app keeps VR working (FrameBridge 72 fps) and gives the window focus; Steam's on-screen keyboard then opens for text
+fields. Unity's TMP_InputField on non-Quest Android waits for the system keyboard (`TouchScreenKeyboardShouldBeUsed`)
+and deselects a frame later unless `isKeyboardUsingEvents` (Android: `InPlaceEditing() && m_HideSoftKeyboard`);
+uGUI InputField's LateUpdate keeps the field when `InPlaceEditing()`. Patch `frame.unity_text_input` rewrites them
+(`mov w0,#0|#1; ret`) at Cpp2IL's **Offset** (= file offset; RVA differs by 0x4000 in Stremio's lib), Cpp2IL
+2022.1 pre-release (Unity 6 / metadata v31; Il2CppDumper can't), cached per libil2cpp sha. `/dev/uinput` has an ACL
+for steamos (Steam Input) → agent v33 `_keyboard` uinput keyboard ("Type on Frame") reaches everything with focus.
+Installing a second APK into a container with `pm install` re-runs Lepton's post-install hook on the **main** app
+(`lepton.active_app_id`; moves its files to /data/steam_app) and corrupts it on the next start (fix: touch the APK →
+re-bake); `cmd_real package install` skips the hook.
+**User reports (2026-10-04, issues #4-#10):** Steam shortcuts go to the signed-in account (`loginusers.vdf`
+MostRecent) else every account (agent v35 `library_users`; it used to refuse with >1 account → Play gave Steam's "Game
+configuration unavailable"); `launch` uses the shortcut's own appid and errors `NOT_IN_LIBRARY`, the app then adds it
+and plays. Unity IL2CPP fixes share one Cpp2IL run (`unity_text_input.Il2cppReturnPatch`, `ALL_TARGETS`, cache keyed by
+global-metadata.dat): `frame.unity_runtime_msaa_off` (OVRManager raises MSAA to 4x at runtime: "Switching to the
+recommended level" → Lucky's Tale restarted the headset; `OVRDisplay.get_recommendedMSAALevel` → 0) and
+`frame.unity_multipass` (Oculus XR Plugin multiview → MultiPass via `OculusSettings.GetStereoRenderingMode`; I Am Cat's
+right eye grey). Both checked against Toy Master's Cpp2IL output, not yet in a headset. VR4 quits itself (System.exit
+after the intro movie) → catalog `use_alt`. **Catalog changes reach existing games** without hardcoded migrations:
+recipes store `catalog_rev` (= `CatalogEntry.rev()`), `library._follow_catalog` re-derives non-user recipes whose entry
+changed; a maintained entry beats the user's shared copy when its `updated`/verified date is later (`catalog._newer`).

+matched by size + SHA-256, words inserted into a copy) — on the device the module is fixed at load ("fixed shader
+module (6488 -> 6512 bytes)"); campaign itself not yet seen in a headset by us. Text settings (kind "str") stay out of
+the Game settings dialog (saving it dropped them). I Am Cat: `GetStereoRenderingMode` is inlined (no call sites) →
+`Il2cppReturnPatch.field_loads` rewrites the field read in `OculusLoader.Initialize` (Cpp2IL gives the field offset,
+`field:<name>`); verified with Toy Master: eye swapchains array=1 ×2 instead of array=2. Builds record `recipe_fp`
+(`patches/base.recipe_fingerprint`, `Patch.revision`): a changed recipe or revised patch shows "Update on Frame".
+Remembered Frames are found again after an address change (`Frame.relocate`: scan, same SSH host key, before

+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 still need a re-analysis. 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 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) →
+`haptic_fix` is now suggested for every game with libOVRPlugin.so (settings detect), BattleSisters works. Ruled out before: ProductName, GetNodePresent, the device-model string itself, exports.
+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
+`patch_clean_up_frida` removes its loadLibrary). It **leaks ~430 GPU mappings (/dev/dri/renderD128) and ~20 MB a
+second** (6.5 GB + swap after 5 min, then 26 fps): page-fault stacks (perf -e page-faults, offsets resolved with the
+process maps + vrclient.so's own symbols; its text segment is at file offset + 0x4000) end in SteamVR's runtime:
+`xrBeginFrame → CSxrCompositorOpenVR::BeginFrame → SubmitExplicitTimingData → CVRCompositorSharedTextures::
+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).
+**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).
+**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).

+- Code and architecture: `CLAUDE.md`, `docs/ARCHITECTURE.md`; per-game symptoms and fixes: `docs/PLAYBOOK.md`.
+- Interface wording: `docs/STYLE.md`. GUI texts go through `tr()`; after changing them run
+  `python scripts/i18n_extract.py`.
+- Translations: see [Translating FramePort](#translating-frameport) below.
+- New fixes are patch modules (`src/frameport/patches/`), with a triage signature (`catalog/triage.yaml`), a PLAYBOOK
+  row and a unit test.
+- Native binaries in `artifacts/` are rebuilt with `python native/build.py` (downloads the NDK).
+
+## Adding a tested game
+
+Tested a game on the Steam Frame? The easiest way is in FramePort: open the game → **…** → **Share working config…**.
+It opens a prefilled GitHub issue with the exact recipe; after review a workflow turns it into
+`catalog/games/<package>.yaml`. Without the app: [working config form](https://github.com/spoopyghosty0/frameport/issues/new?template=working-config.yml). Something doesn't run: the game's
+**Report a problem…** (diagnostics zip, personal data removed) or the [problem report form](https://github.com/spoopyghosty0/frameport/issues/new?template=bug-report.yml).
+After catalog changes, regenerate the games list: `python scripts/compat_list.py`.
+
+## Translating FramePort
+The app's texts (screens, help, patch and setting descriptions) can be translated; the command line, logs and
+diagnostics stay English. No programming needed:
+
+1. Copy `src/frameport/locales/template.json` to `src/frameport/locales/<code>.json`, where `<code>` is the language
+   code (`de`, `fr`, `pt`, `ja`, …).
+2. Add `"_language": "<the language's own name>"` (e.g. `"Deutsch"`); it's shown in Settings → Language.
+3. Fill in the values. Each key is the English text; leave a value empty to keep the English text. Plural entries
+   have a list value: `["<one>", "<other>"]`. Keep `{placeholders}` such as `{title}` or `{n}` exactly as they are,
+   and keep `…`, `·` and line breaks where the English has them.
+4. Try it: `uv run frameport-gui`, choose the language in Settings → Language, restart FramePort.
+5. Open a pull request with the file. When the English texts change, `python scripts/i18n_extract.py` refreshes the
+   template; new texts then show in English until they're translated.
+
+Wording rules for English (and a guide for tone) are in `docs/STYLE.md`.
+
+## Ground rules
+- Use only games you own. Contributions that help bypass DRM, licence or entitlement checks, or that add game files,
+  are not accepted.
+- Never commit personal data (IP addresses, user names, home paths, Steam IDs).
+- By contributing you agree to license your work under GPL-3.0-only.

 # FramePort
 
-FramePort installs Meta Quest standalone games and Oculus Rift PC VR games on the **Valve Steam Frame**. It patches a
-game so it runs on the Frame's runtimes, copies it to the headset over Wi-Fi and adds it to the Frame's Steam library
-with artwork.

+![Platforms](https://img.shields.io/badge/platforms-Windows%20%7C%20macOS%20%7C%20Linux-blue)

+
+Install games that target the Meta Quest, Android, or general PCVR onto your **Valve Steam Frame**. FramePort handles everything from uploading game files, setting up your Frame, injecting compatibility patches, and adding shortcuts to your Steam library. FramePort aims to be as simple as possible by taking advantage of the fact that the Steam Frame runs on Linux.
 
 ![Library](docs/images/library.png)
 
-## Purpose
+> **Notice:** FramePort explicitly does NOT download, share, or unlock games. You must provide legally obtained game
+> executables. Core features of FramePort simply download and wrap other published tools (see [Built on](#built-on))
+> with patches provided by FramePort adding a hardware compatibility layer. This enables users to use games/apps legally
+> purchased on sites like [SideQuest](https://sidequestvr.com/). 
 
-FramePort is a **proof of concept**: it shows that VR software built for other platforms (Meta Quest, Oculus Rift) can
-run on the Steam Frame with a translation layer and a few targeted fixes. Most of the work is done by the projects
-FramePort wraps (see [Built on](#built-on)); FramePort selects and applies their fixes per game, adds Steam
-Frame-specific patches, and handles installing, testing and launching.
+## Features
 
-FramePort is **not a piracy tool**. It does not download, share or unlock games, and it does not remove DRM, licence or
-entitlement checks. Use it only with games you own. Games that check their licence through the Oculus Platform SDK are
-marked as not runnable on the Frame.
+- **Painless setup:** one short command on the Frame. No root, no `sudo`, no password.
+  [What it changes](docs/FRAME_SETUP.md).
+- **Type on Frame:** use your computer's keyboard on the Frame: in VR apps, Android apps, Steam and the desktop.
+  [More](#type-on-frame).
+- **One click per game:** convert, patch, sign, upload, add to Steam with artwork, launch test. Artwork that can't be found automatically can be picked from the stores or replaced with your own images.
+- **Per-game recipes:** a tested catalog plus detection rules; every patch explained in plain words.
+- **FrameBridge:** FramePort's OpenXR adapter emulates what the Frame natively lacks (passthrough, room, controller models,
+  curved and 360° layers); game settings as simple switches.
+- **Beyond Quest:** Android apps as windows, PC VR via Proton or Revive, Windows (non-VR) games via Proton, a Files
+  tab with drag and drop.
+- **Linux apps:** install arm64 Linux apps (AppImage, a folder, or a zip/tar archive) on the Frame with a Steam
+  shortcut; they run natively on SteamOS.
+- **Screenshots tab:** the screenshots you took in the headset, sorted by game (matched by play time) and day;
+  view them and download them to your computer.
+- **Live view tab:** watch what the headset shows, with sound, in a browser window on your computer.
+- **Self-updating** releases, redacted diagnostics, one-click problem reports and working-config sharing.
 
-## Getting started
+## Quick start
 
-1. **Download** the archive for your computer from the
-   [latest release](https://github.com/spoopyghosty0/frameport/releases/latest) and extract it anywhere:
+1. [Download](https://github.com/spoopyghosty0/frameport/releases/latest) and unzip the build for Windows, macOS
+   (Apple Silicon) or Linux, then start FramePort.
+2. **Connect the Frame** (once):
+   1. In FramePort click **Steam Frame → Show setup command**. Keep FramePort open; the Frame and your computer must
+      be on the same Wi-Fi.
+   2. On the Frame open the **SteamVR dashboard → Launch a program → Desktop**: the Linux desktop opens on a virtual
+      screen.
+   3. Open the app menu (bottom-left corner of that desktop) → **System → Konsole** (or search for Konsole).
+   4. Type the command FramePort shows exactly as shown (on-screen keyboard or any USB/Bluetooth keyboard) and press
+      **Enter**. This will run the following [bash setup script](bootstrap/bootstrap.sh).
+   5. After a few seconds the desktop closes by itself (Steam restarts once); that's expected. If
+      Steam asks to install **Lepton**, confirm it. FramePort shows the Frame as connected within a minute. No
+      password needed.
+3. **Add games → Scan a folder** with your game backups (APK + OBB, or PC VR game folders).
+4. Open a game → **Install on Frame**, then play it from the Frame's Steam library.
 
-   | Computer | File | Start |
-   |---|---|---|
-   | Windows 10/11 (x64) | `FramePort-windows-x64.zip` | `FramePort.exe` |
-   | macOS (Apple Silicon) | `FramePort-macos-arm64.zip` | `FramePort.app` |
-   | Linux (x64) | `FramePort-linux-x64.tar.gz` | `FramePort/FramePort` |
+Full guide, firewalls and troubleshooting: [docs/INSTALL.md](docs/INSTALL.md). Questions (e.g. how to lay out games
+with OBB files): [docs/FAQ.md](docs/FAQ.md).
 
-   The builds are self-signed, so the first start shows a warning: Windows → **More info → Run anyway**;
-   macOS → right-click the app → **Open**. Details: [docs/INSTALL.md](docs/INSTALL.md).
-2. **Get the tools**: on first start FramePort downloads what it needs (Java runtime, OVRPort, apksigner) into its own
-   folder. Nothing is installed system-wide.
-3. **Connect the Frame**: turn on Developer Mode on the Frame (Settings → System → Developer). In FramePort open
-   **Steam Frame**; if the Frame isn't listed, switch it to Desktop mode, open Konsole and paste the one command
-   FramePort shows. This is needed once.
-4. **Add games**: **Add games → Scan a folder** with your Quest game backups (APK + OBB) or Rift game folders.
-   FramePort identifies each game and fetches its artwork and store details.
-5. **Install**: open a game and click **Install on Frame**. FramePort patches, checks, uploads and adds the game to the
-   Frame's Steam library, then runs a short launch test.
-6. **Play**: put the headset on and start the game from the Steam library (or click **Play on Frame**).
+## Type on Frame
 
-![Game page](docs/images/game.png)
+Typing in VR is painful, so FramePort turns your computer's keyboard into a keyboard for the Frame. Open **Type on
+Frame** (keyboard icon on the sidebar's Frame card, the Steam Frame page, or a game's menu), select a text field in
+the headset and type: searches, logins, chat, in any app, in Steam or on the desktop. Paste longer text to type it in
+one go. Nothing to install: FramePort adds a virtual keyboard on the Frame while the window is open, without root.
 
-FramePort updates itself: when a new version is released, the Library shows **Update now**.
+![Type on Frame](docs/images/type-on-frame.png)
 
-## What works
+Unity apps whose text fields close the moment you select them on the Frame (no system keyboard there) get a per-game
+fix, so Steam's on-screen keyboard and Type on Frame work in them too.
+[Details](docs/INSTALL.md#typing-on-the-frame).
 
-The built-in catalog has tested settings for 38 games (27 work, 5 work with known issues, 6 can't run on the Frame).
-Other games get suggested patches from detection rules; each suggestion states its reason, and every patch can be
-switched on or off under **Customize**.
+## Screenshots
 
-![Patches](docs/images/patches.png)
+Screenshots you take in the headset show up in FramePort's **Screenshots** tab, grouped by day and matched to the game
+you were playing. Open one full size, step through them, and download single shots, a selection or all of them to
+your computer.
 
-- Quest games run in Valve's Android runtime (Lepton). 32-bit-only Quest games can't run (the Frame has no 32-bit ARM
-  support).
-- Rift games run through Proton on the Frame (experimental) or on a Windows PC with SteamVR, streamed to the Frame.
-  Games that use the Oculus Platform SDK need the Oculus app and a licence, so they run on the PC only.
-- Automated launch tests confirm a game starts; visuals can only be checked in the headset.
+![Screenshots](docs/images/screenshots.png)
 
-![Steam Frame](docs/images/frame.png)
+![Screenshot viewer](docs/images/screenshot-viewer.png)
+
+## Live view
+
+The **Live view** tab streams what the headset shows, with its sound, to your computer: click **Start live view** and
+it opens in your default web browser (full screen with a double-click; click **Sound on** to hear it, as browsers start
+videos muted). Pick 360p to 1080p, or the headset view's full size. The picture comes from SteamVR's built-in headset
+view on the Frame and is encoded there while you watch (about one CPU core), so stop it when you're done. It's black
+while the headset sleeps.
+
+## Compatibility
+
+If a game has already been tested with FramePort, it will automatically use the optimal game config. Otherwise, FramePort
+will attempt to guess key patches. If you find a new config that works for an app you are testing, please consider submitting it to the community!
+
+**[List of tested games](docs/GAMES.md)**
+
+**Tested something? Share it.** In FramePort open the game → **…** → **Share working config…** (it fills in the
+recipe for you) or **Report a problem…** (attaches a diagnostics zip with personal data removed). Without the app:
+[share a working config](https://github.com/spoopyghosty0/frameport/issues/new?template=working-config.yml) · [report a problem](https://github.com/spoopyghosty0/frameport/issues/new?template=bug-report.yml). Shared configs become built-in recipes for everyone.
 
 ## Built on
 
-FramePort is a front end for other projects; most of the functionality comes from them:
-
-| Project | Used for |
-|---|---|
-| [OVRPort](https://github.com/Android-XR-Bridge/OVRPort) (overport, originally [ovrport/app](https://github.com/ovrport/app)) | Converts Quest games to OpenXR: its CLI applies the game patches and supplies the OpenXR loader; FramePort also includes its VrApi→OpenXR adapter |
-| Valve Lepton, Proton and SteamVR | Run Android games, Windows games and OpenXR on the Frame |
-| [Revive](https://github.com/LibreVR/Revive) (LibreVR) | Runs Oculus Rift games on OpenXR / SteamVR |
-| Mesa (Zink) | OpenGL ES on Vulkan on the Frame |
-| [Khronos OpenXR SDK](https://github.com/KhronosGroup/OpenXR-SDK) | OpenXR headers for the native layers |
-| Eclipse Temurin, Android apksigner, Android NDK | Java runtime, APK signing, building the native layers |
-| [Flet](https://flet.dev) | The desktop app |
-| OculusDB, Steam store | Game descriptions, genres and artwork |
-
-FramePort's own parts: game detection and recipes, the Steam Frame OpenXR adapter (FrameBridge) and the other native
-fixes in `native/`, the installer agent that runs on the Frame, and the desktop/command-line app.
-
-## Command line
-
-The same functions are available as `frameport` (included in the source tree; also released as a Python wheel):
-`frameport scan`, `frameport build`, `frameport install`, `frameport test`, `frameport update`. Run
-`frameport --help` for the full list.

+# 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`.

+# 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**.

+  back/home/recents bar is drawn over the app's own controls; `qemu.hw.mainkeys=1` removes it, but it's only read at

+- `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.
+
+## Text input
+
+- Lepton's Android has no on-screen keyboard (IME) and VR apps run headless, so no Android window has keyboard focus
+  and key presses (Steam's keyboard, USB/Bluetooth keyboards, `input text`) don't reach VR apps. The app folder's
+  `lepton-show-flatscreen` marker shows the window (VR keeps working) and gives it focus; Steam's on-screen keyboard
+  then opens for its text fields (FramePort patch `device.text_input_window`).
+- `/dev/uinput` is writable by the steamos user (ACL for Steam Input): a uinput virtual keyboard works like a real
+  one everywhere (FramePort's "Type on Frame", agent `_keyboard`).
+- Unity text fields close without a system keyboard; see `frame.unity_text_input` in PLAYBOOK.md.

+# Frame setup: what changes, networks, undoing it
+
+For the steps themselves see [INSTALL.md](INSTALL.md#connecting-the-steam-frame).
+
+## What the setup changes
+
+The setup command runs [`bootstrap/bootstrap.sh`](../bootstrap/bootstrap.sh), served by the app over your
+local network. Everything it changes:
+
+| Change | Where | How to undo |
+|---|---|---|
+| Turns on **Developer Mode** (only if it's off). Steam restarts once, which closes Desktop Mode; the rest of the setup finishes on its own as a user service (log: `~/.cache/frameport-setup.log`). | `"DevModeEnabled" "1"` in `~/.local/share/Steam/config/config.vdf` (old file kept as `config.vdf.before-frameport`), then Valve's own `steamos-polkit-helpers/steamos-devkit-mode --enable`. That helper enables the SSH server (`sshd`), the devkit service that makes the Frame findable on the network, the remote-desktop and debug services, and system crash dumps. | Settings → System → Developer → Developer Mode off. Valve's helper switches all of those services off again. |
+| Lets the app's SSH key in. | One line ending in `frameport` in `~/.ssh/authorized_keys`. The folder and file are created if missing. | Delete that line. |
+| Configures podman for Lepton. Rootless podman leaks one kernel keyring per container start, and after about 200 game starts every game fails. | `[containers]` / `keyring = false` in `~/.config/containers/containers.conf`. | Remove those lines. |
+| Asks Steam to install **Lepton** (Valve's Android runtime, Steam app 3029110) if it's missing. You confirm it in Steam. | Steam library | Uninstall it in Steam. |
+
+The script runs as your user: no root, no `sudo`, no password. The only system-level change, Developer Mode, is
+made by Valve's own helper, the same one the Settings switch uses. If Developer Mode can't be turned on
+automatically, the script asks you to turn it on in Settings → System → Developer and run the command again.
+
+Nothing else on the system is touched: no packages, no read-only-filesystem changes, no polkit rules. The script
+also leaves two files: `~/.cache/frameport-setup.sh` (the part that runs on its own) and its log.
+
+**Later, the app adds** (all as your user, no root, no `sudo`):
+- FramePort's helper in `~/.local/share/frameport/`;
+- the games, each with a launcher and its data in `~/Applications/quest-frame/<package>/`;
+- their Steam library entries and artwork (`shortcuts.vdf` + `config/grid/`);
+- for PC VR games: an OpenXR layer (`~/.local/share/openxr/1/api_layers/explicit.d/XR_APILAYER_FRAMEPORT_timefix.json`)
+  and, when the first PC VR game is installed, Valve's ARM64 Proton and its Steam Linux Runtime (Steam downloads them;
+  Steam restarts once).
+
+**Settings → Uninstall FramePort → Also remove from the Frame** deletes the games, their Steam entries, the helper
+folder, the OpenXR layer and the setup script's files. Developer Mode, the SSH key line, the podman setting, Lepton
+and Proton stay. Undo them as shown above or in Steam.
+
+## Network and firewalls
+
+The setup command is the only time the Frame connects to your computer: it downloads the script from FramePort on
+TCP port 8765 (8766/8767 if taken), only while the setup command is shown and for at most 30 minutes. Everything
+else goes from the computer to the Frame. If the command just says "timed out", the setup page shows what is likely
+blocking it after about 45 seconds:
+
+- **Windows:** allow FramePort (or Python, when running from source) when Windows asks. On a network Windows treats as
+  **Public** it stays blocked unless you allow public networks; set your home network to Private in Windows'
+  network settings instead.
+- **macOS:** with the firewall on (System Settings → Network → Firewall), allow incoming connections for FramePort
+  when asked.
+- **Linux:** firewalld: `sudo firewall-cmd --add-port=8765/tcp` (until the next restart). ufw:
+  `sudo ufw allow 8765/tcp`, afterwards `sudo ufw delete allow 8765/tcp`.
+- **WSL:** Windows' Hyper-V firewall blocks connections into WSL without asking. FramePort adds a temporary rule for
+  the setup ports (one admin prompt) and removes it again when setup is done or after 35 minutes. WSL must use
+  mirrored networking: `networkingMode=mirrored` under `[wsl2]` in `%UserProfile%\.wslconfig`, then `wsl --shutdown`.
+- Or skip the setup command and use the devkit pairing (see [INSTALL.md](INSTALL.md#connecting-the-steam-frame)): it needs no connection into your computer.

 ## Connecting the Steam Frame
 
-1. On the Frame: Settings → System → Developer → turn on **Developer Mode**. The Frame and the computer must be on the
-   same network.
-2. In FramePort open **Steam Frame**. A Frame in Developer Mode appears in the list.
-3. First time only: on the Frame switch to Desktop mode (Steam button → Power → Switch to Desktop), open Konsole and
-   run the command FramePort shows. It enables SSH, authorises this computer and installs Valve's Android runtime
-   (Lepton) if needed.
+The Frame and the computer must be on the same network.
+
+1. In FramePort open **Steam Frame** and click **Show setup command**.
+2. First time only, on the Frame:
+   1. Open the **SteamVR dashboard → Launch a program → Desktop**: the Linux desktop opens on a virtual screen.
+   2. Open the app menu (bottom-left corner of that desktop) → **System → Konsole** (or search for Konsole).
+   3. Type the command FramePort shows exactly as shown (on-screen keyboard or any USB/Bluetooth keyboard) and press
+      **Enter**. It looks like `curl -fsS 192.168.1.20:8765/1a2b3c4d | bash`: your computer's address, then a
+      one-time code.
+   4. After a few seconds the desktop closes by itself (Steam restarts once); that's expected. If
+      Steam asks to install **Lepton** (Valve's Android runtime), confirm it.
+
+   FramePort connects by itself within a minute. No password is needed. The command lets FramePort in and turns on
+   **Developer Mode** (which includes SSH); everything it changes is listed in [FRAME_SETUP.md](FRAME_SETUP.md).
+3. Later starts: a Frame in Developer Mode appears in the list and FramePort connects to it automatically. (If you
+   turn Developer Mode off in Settings → System → Developer, turn it on again there.)
+
+**Without Konsole:** turn on Developer Mode yourself (Settings → System → Developer). The Frame then appears under
+**On your network**. On the Frame open Settings → Developer → **Pair new host**, then click **Connect** in FramePort
+and approve it on the Frame (Valve's own devkit pairing; it only sends this computer's key to the Frame). Install
+Lepton from the Steam Frame page afterwards if it's missing.
+
+### 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**.
+
+## Installing games
+
+- **Install on Frame** on a game's page (or select several in the Library and install them together). Installs run
+  one after another in the background; **Activity** shows the current one at the top.
+- **Update all** reinstalls every game whose build changed (e.g. after a FramePort update). Questions that need an
+  answer (e.g. Oculus games that can't run on the Frame) are asked once, for all games.
+- If the Frame goes to sleep, turns off or leaves the Wi-Fi, the queue **waits** and continues once it's back; uploads
+  pick up where they stopped. While installs run, FramePort keeps the Frame from going to sleep. Before a large batch
+  it checks the Frame has enough free space.
+- Your own game files are never changed. The converted copy is temporary: it's removed once the game is on the Frame
+  (Settings → Installing: keep them, or remove all now).
+- **Game settings…** (game menu or the Steam Frame page): sharpness, refresh rate, controllers, menus, 360° video and
+  mixed-reality options in plain words, only those that matter for the game. Changes are kept with the game and,
+  when it's installed, used the next time it starts.
+- Ordinary Android apps (no VR) are installed unchanged and shown as a flat window in the headset. Android's
+  back/home/recents buttons are hidden by default (patch **Hide Android's navigation bar**).

+reality), showing only what matters for that game. Changes are kept with the game and reach the Frame right away.
+

+
+## Typing on the Frame
+
+- **Type on Frame** (Steam Frame page, a game's menu, or the keyboard icon on the sidebar's Frame card): while the
+  window is open, this computer's keyboard works as a keyboard plugged into the Frame. Select a text field in the
+  headset (in an app, Steam or the desktop) and type; Esc and shortcuts go to the Frame too. Paste longer text into
+  the box to type it in one go (US keyboard layout). Click **Done** to disconnect.
+- **Steam's on-screen keyboard** opens for text fields of apps shown as a window (2D apps, and VR apps with
+  **Show the app's Android window**). Steam lists that window as **Gamescope** (the Frame's display compositor);
+  leave it open: it's what receives the typing, the VR view isn't affected.
+- **Unity apps whose text fields close at once** (a caret flashes, nothing can be typed): FramePort suggests
+  **Make Unity text fields work** for them. The first time, it downloads Cpp2IL (a tool that finds the right spot in the
+  game's code, ~17 MB). Games added before this version: open the game's menu → **Analyze again**, then reinstall.
 
 ## Updating
 
+**Game configs** (the tested recipes in the catalog) update by themselves: FramePort checks GitHub every 6 hours for
+newly confirmed or fixed configs and uses them without a FramePort update; a game whose recipe changed then shows
+**Update on Frame**. Configs that need a newer FramePort are skipped until you update. Settings → Data shows the last
+check (**Check now**) and turns this off.
+

+## Linux apps (arm64)
+
+The Frame runs SteamOS on an arm64 CPU, so native Linux apps built for **aarch64/arm64** run on it directly (no
+Android container, no Proton). **Add games → Add a Linux app (arm64)…** takes an AppImage or a `.zip`/`.tar.gz`/
+`.tar.xz` archive; **Add a Linux app folder…** takes an unpacked app. FramePort finds the program that starts it (the
+game page's **Change…** picks another one) and whether it's a VR (OpenXR) app. **Install on Frame** uploads it
+unchanged and adds it to the Frame's Steam library, tagged "Linux app on Frame"; Play, launch tests and Uninstall
+work like for other games.
+
+- x86_64 builds can't run on the Frame: FramePort says so when you add one. Look for an aarch64/arm64 download.
+- The app must bring the libraries SteamOS doesn't have. If some are missing, the install reports them and the game
+  page lists them: look for a build that includes them.
+- From the command line: `frameport add-linux <AppImage, folder or archive> [--exe <program>]`.
+
+## Files on the Frame (videos, documents, mods, saves)
+
+The **Files** tab manages files on the Frame over the same connection as installs; no other transfer app is needed.
+Pick a location, browse folders, and use **Upload files** / **Upload folder**, **New folder**, or the download, rename
+and delete buttons on each entry. Right-click an entry (or the empty space) for the same actions in a menu. Tick
+several entries (or the box above the list for all), or click and drag across them, to download or delete them
+together; a right-click on one of them then acts on all. The **Screenshots** tab and the **Library** work the same
+way: right-click for a menu, drag across cards to select several. In the downloaded app you can also drag files and folders from Explorer / Finder / your file manager onto
+the list to upload them into the open folder. Uploads and downloads run in the Activity panel, resume after an interruption and
+skip files that are already there.
+
+- **Videos**, **Downloads** and **Documents** appear inside every Quest game as `/sdcard/Movies`, `/sdcard/Download`
+  and `/sdcard/Documents`. Apps find files by browsing folders; Android's media index doesn't work on the Frame.
+- Under **Game storage**, each installed game has its own `/sdcard` (mods, saves). A game's menu → **Add videos and
+  files…** opens it. Video players that list only their own folder (e.g. 4XVR's "Internal Storage" = `4XPlayer`) find
+  videos uploaded into that folder.
+- **Home folder** shows everything in the Frame's home folder (hidden files with **Show hidden files**).
+
+Command line: `frameport frame send <files> --dest videos` (`frameport frame storage` lists the destinations).

 ## Debugging techniques that worked

 - 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).
+- 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-*`).

+# Writing style for FramePort's interface
+
+Short rules so every screen, help text and doc sounds the same. Code style is enforced by `ruff`.
+
+## Words
+- **Steam Frame** on first mention in a screen or document, **the Frame** after that. **Headset** only for the
+  physical device you wear ("put the headset on").
+- **Quest game** for Meta Quest apps, **Android app** for ordinary Android apps, **PC VR game** for Windows VR games.
+  Say Oculus or Rift only for games that use Oculus's own SDK.
+- **Patch** for anything in a game's patch list (never "fix" for the same thing). **Recipe** for a game's chosen
+  patches and settings.
+- Tools by their names: OVRPort, Revive, Proton, Lepton, SteamVR.
+- **Install** (first time), **Update** (a newer build), **Reinstall** (the same build again); **Play** starts a game.

+## Form
+- Buttons and headings in sentence case ("Add games", "Report a problem…"); one label per action everywhere.
+- "…" at the end of a label when the action asks for more input (a dialog, a file picker).
+- Sentences end with a period, including tooltips and help texts; labels don't.
+- "and", not "&", in text. An em dash (—) for asides, a middle dot (·) between short facts.
+- Sizes in GiB/MiB (`i18n.fmt_size`), dates as YYYY-MM-DD HH:MM (`i18n.fmt_datetime`).
+- US spelling (customize, analyze, color).
+- Plain, technical wording: say what happens ("Steam restarts once"), no marketing adjectives.
+
+## Translations
+- Every text the GUI shows goes through `tr("…")` or `tr_n("…", "…", n)` (see `src/frameport/i18n.py`); use
+  templates with `.format()`, never f-strings inside `tr()`, and never decide anything from a displayed text.
+- After changing texts run `python scripts/i18n_extract.py` (a test checks the template is current).
+- CLI output, logs, diagnostics, catalog notes and launch-test diagnoses stay English.

 | `adapter/` | `{arm64-v8a,armeabi-v7a}/libopenxr_loader_generic.so` | **FrameBridge**: replaces overport's generic loader (which is renamed `libopenxr_loader_original.so`) and fixes Steam Frame runtime gaps. Hooks xrCreateInstance, swapchains, xrEndFrame, spaces, xrPollEvent, … everything else is forwarded by `gen_forwarders.py`-generated tail calls. `scene_emu.c` = Meta scene/spatial-entity emulation; `flip_vk.c` = Vulkan blit for VERTICAL_FLIP quads. `session_fixes.c` = per-game session fixes, all off by default and hooked only when on (`layer_debug` diagnostics, `stable_local`, `focus_hold`, aim correction `aim_pitch/aim_yaw/aim_forward`, `refresh_rate`); `layer_emul_gl.c` = `equirect_emul` (GLES sessions only): 360° equirect/equirect2 layers become one adapter projection layer, drawn by a worker thread with its own EGL context shared with the app's: each 360° image is converted to a cube map only when it changes, and the view is redrawn only after a 4° head turn (GL/EGL resolved with dlopen, so Vulkan games never load them); `layer_math.h` = their pose/face math, tested on the host by `tests/test_layer_emul.py`. `render_model.c` = XR_FB_render_model emulation (setting `controller_models`, off by default): serves `files/framebridge/controller_{left,right}.glb`, which the agent converts on the Frame from SteamVR's own Frame controller render models (never shipped by FramePort); tested on the host by `tests/test_render_model.py`. Settings: `libframe_settings.so` in the APK + `settings.conf`/`framebridge.conf` on the Frame. |
 | `vrapi-bridge/` | `arm64-v8a/libvrapi.so` | VrApi → OpenXR bridge from [Android-XR-Bridge/OVRPort](https://github.com/Android-XR-Bridge/OVRPort) `native/vrapi` at 5e7df52 (GPL-3.0, `LICENSE.upstream`; unchanged upstream as of OVRPort v1.2.5, which ships the unpatched code as its opt-in `patch_vrapi_openxr` in experimental CLI builds), with our changes in `upstream-patches/`: GLES sessions + GL texture swapchains, cylinder→quad layers, GL vertical flip, UNORM↔sRGB format twins, 30 s VR-mode deadline, VALID-only recenter, loading-icon layers skipped, diagnostics behind `-DOVP_GL_DIAG`. |
 | `platformcompat/` | `arm64-v8a/libovrplatformcompat.so` | Real `ovrMessageType_ToString` (same fork, `native/platform`). |
+| `langpack/` | `arm64-v8a/libfp_langpack.so` | Language packs for the Meta Platform SDK (patch `frame.langpacks`, opt-in). overport's platform loader is a dispatcher in front of Meta's own loader and answers `ovr_LanguagePack_GetCurrent/SetCurrent` with `return 0` (no reply ever). 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`. Host-tested against a stand-in loader (`tests/test_langpack.py`, plain `cc`, no NDK); the bionic/headset side is unverified. |
 | `glshim/` | `arm64-v8a/libglshim.so` | Mesa GLSL compatibility for GLAD engines (hooks eglGetProcAddress): comments out `#pragma` before `#extension`, enables `GL_EXT_shader_implicit_conversions`, hides GL_OVR_multiview (`gl_hide_multiview`, default 1) and logs failed shaders. `-DGLSHIM_TRACE` adds per-FBO draw/error tracing. |
 | `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). |

+// 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

+//
+// That Unity drives OVRPlugin with the legacy frame loop: ovrp_Update2(render step, frame index, ...) on the main
+// thread, then ovrp_BeginFrame / ovrp_EndFrame on the render thread. It never calls ovrp_WaitToBeginFrame, which
+// newer OVRPlugin builds (OVRPort's OpenXR OVRPlugin) need to call xrWaitFrame: no frame ever begins, OVRPlugin logs
+// "CompositorOpenXR::Update called for frame N outside of frame bounds" thousands of times a second and the Frame's
+// dashboard freezes (Accounting+, Unity 2017.4).
+//
+// FramePort renames the "ovrp_Update2" lookup in libunity.so to "fpov_Update2" (same length) and adds this library to
+// libOVRPlugin.so's DT_NEEDED, so Unity's dlsym on the plugin finds this function: it waits for the frame first (once
+// per frame index, render step only), then calls the real ovrp_Update2.

+// messages that answer them, to find a request that never gets an answer (a game waiting forever, e.g. Vader
+// Immortal after its intro). Nothing is answered or changed here: every call goes to the real function.
+//
+// Wiring: this library is the first DT_NEEDED of the game's engine library, so the engine's ovr_* imports resolve to
+// the exports below. Each export is a tiny assembly stub that saves the argument registers (x0-x8, d0-d7), asks
+// trace_before() for the real function (dlsym on the platform loader's handle, which also finds the language-pack
+// library's functions when frame.langpacks is on), calls it with the original registers, then reports the result to
+// trace_after(). Signatures don't matter (functions with more than 8 integer arguments would; the Platform SDK has
+// none). Logcat tag fp_ovrtrace.
+//
+// What is logged: the first calls of every function (argument 0 and the result), every message ovr_PopMessage
+// returns (type, request id, error flag), and every 10 s the request ids no message has answered yet with the
