Fossilize crashed Deadpool VR on uninitialized attachment-reference pNexts (several, in FVulkanRenderPass and the render-target layout) → `frame.vk_sanitize` = `native/vkshim` (engine's `dlopen("libvulkan.so")` string → `libfp_vk.so`, wraps vkCreateRenderPass2/KHR, drops unreadable/wrong-sType pNexts; verified: game runs). overport's dispatcher aborts on swapchains > 4096 px (`cmp wN,#4096` in xrCreateSwapchain) → `frame.swapchain_limit` (verified with 4XVR, 7680×3840 accepted by the runtime). Both are default-on (parity classifies their rewrites as
-"expected"; library migration `quest_binary_fixes_v2`). The adapter shows cylinder layers (4XVR's movie screen) as ~15° quad strips (`cylinder_strips`, setting
-`cylinder_strips`); the runtime composites them at full resolution. Equirect (360°) layers are dropped: drawing
-them ourselves (GLES renderer in xrEndFrame: stutter, never showed 4XVR's VR video; Vulkan renderer: hung the
-Frame's GPU in AC Nexus; reading the newest *released* image broke 4XVR's theatre) was removed again on the owner's
-request — don't retry without a new approach. Converted layers must count as "swapped" or the original layer list
-is submitted (runtime returns -2 for every frame). A focus debounce (hiding the Frame's brief
-FOCUSED→VISIBLE→SYNCHRONIZED dips, which make 4XVR recenter) was also removed: AC Nexus stayed black with it (it
-hid 521 ms focus changes at start). The new approach (below) is per-game, off the app's render thread, GLES-only.
-
-**360° layers / 4XVR (2026-09-30):** the Frame's Android SteamVR runtime (`/opt/steamvr/bin/androidarm64/vrclient.so`,
-mounted in Lepton as `/data/steamvr/runtime`) only composites quad + projection layers (cube/cylinder/equirect(2)
-are enum names only) — nothing to unlock. Per-game adapter settings (off by default, hooks installed only when on):
-`equirect_emul` (GLES only: a worker thread with a shared EGL context converts each 360° image to a cube map when it
-changes and draws one adapter projection layer from it for every frame with exactly that frame's views (the app's own
-projection views, else xrLocateViews at displayTime); xrEndFrame waits ≤6 ms for the worker's CPU submit, never the
-GPU. Learned in the headset: quads can't be a background (the Frame draws quad layers above all projection layers
-whatever the order: hid 4XVR's balcony/controllers), and the Frame doesn't reproject a projection layer from its own
-pose (images drawn only after head turns, or ahead from xrWaitFrame and sometimes late, wobbled);
-`equirect_flip/face/res/fps/stereo`), `stable_local`, `focus_hold` (only after 3 s FOCUSED, dips <600 ms),
-`aim_pitch/aim_yaw/aim_forward`, `refresh_rate`, `layer_debug` (diagnostics); focus_hold is default-on since 2026-10-05. 4XVR re-creates LOCAL spaces every 2–4 s
-(menu recentring suspect); its theatres are baked 7680×3840 equirect2 images (`assets/100.png` …). Test 360° videos
-(NASA, public domain) are in the Frame's ~/Videos; copies in `~/Downloads/frameport-360`. 4XVR's "Internal Storage"
-lists its own `/sdcard/4XPlayer`, not Movies: agent v25 `link_media` hard-links sent files into an app's own top-level
-folder (`app_media_dirs`), `frameport frame send --app <pkg>`, GUI game page "Add videos" (players) / "Add videos &
-files…". A 4XVR webm stereo swapchain was refused with XR_ERROR_LIMIT_REACHED (-10) → right eye grey; our projection
-swapchain was halved (1536/eye) in case memory is the limit (unverified). Frame data snapshot
-(SteamVR runtimes, Lepton scripts, logs; never commit Valve binaries): `~/frameport-research/frame-data-2026-09-30/`.
-Not yet verified in the headset.
-
-**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`).
-**Round 2 of reports (2026-10-04):** VR4's campaign hang = one fragment shader reading an uninitialized loop counter
-(reporter's capture): vkshim `vk_shader_fix` setting (`<size>:<sha256>:<offset>:<words>`, from the recipe's `adapter:`;
-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
-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`); lost again (agent v89): Steam
-ignores FramePort's entries on that Frame, so `add_devkit_entry` adds the devkit entry instead (`added` gets `via:
-devkit`) and only reports an error if that fails too. 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). Godot 4.2-4.4 (Kotlin `as ClipboardManager`,
-GitHub #134 EndoparasiticVR) → `frame.godot_clipboard` (nops the `Intrinsics.checkNotNull` before that check-cast; Godot's
-clipboard methods return at once; analysis `godot_clipboard`, ANALYSIS_VERSION 10; checked on real godot-lib/templates
-4.2.2-4.4.1, not on the device; 4.1 and 4.5+ don't throw). 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).
+**Crash backtraces:** Lepton writes tombstones only to `lepton-logcats/steamlaunch-<appid>/logcat-crash.log` (launch tests return `crash_log`). Fossilize loads into every app (userdebug guest) → `frame.vk_sanitize` (`native/vkshim`); overport's dispatcher aborts on swapchains > 4096 px → `frame.swapchain_limit`; cylinder layers → quad strips (`cylinder_strips`).

+**Companion apps / intents:** a second APK can run inside a game's Lepton container, but Lepton turns every `android.intent.action.VIEW` with data into `steam://openurl` → "open in external player" hand-offs can't work; Lepton installs exactly one `*.apk` per app folder. → docs/DEVICE_NOTES.md#companion-apps--intents-stremio--4xvr
+**Text input:** Lepton's Android has no IME and VR apps run headless (no focused window); `lepton-show-flatscreen` keeps VR and gives focus + Steam's keyboard (`device.text_input_window`); `frame.unity_text_input` patches Unity's TMP_InputField/InputField at Cpp2IL offsets; agent `_keyboard` = uinput "Type on Frame". `pm install` of a second APK corrupts the main app (`cmd_real package install` skips the hook). → docs/DEVICE_NOTES.md#text-input-stremio-vr

+**Round 4:** XR_KHR_android_surface_swapchain is listed but unsupported → adapter `surface_emul` (default on, `native/adapter/surface_swapchain.c`); save folders without u/g+rwx → launch.sh `fix_perms`; Lucky's Tale OOM (no fix); `perf` works as steamos (gdb blocked); QuestCraft JRE, WiiCompiled import by hand (Lepton has no document picker). → docs/DEVICE_NOTES.md#round-4-2026-10-04-surface-swapchains-save-folder-permissions
+**Steam library failures (GitHub #21/#30/#41/#42):** on some Frames Steam never loads FramePort's shortcuts.vdf entries (Play → AppError_9) → fallback: register through Steam's devkit interface (`devkit-1 … create-shortcut`, `~/devkit-game/<id>/`; `devkit_appid`, `devkit_appid_from_log`, `devkit_unregister`, `copy_grid_art`; ids: letter first, letters/digits/_ only); `collect_diag` adds `steam_library`. Cause still unknown. → docs/DEVICE_NOTES.md#steam-library-failures-and-the-devkit-fallback-github-21304142
+**Exit game (GitHub #36):** `Apps.TerminateApp` (Steam CEF devtools on 127.0.0.1:8080) closes games; launch.sh ends the game when its parent reaper is gone (`upgrade_launchers` adds it). → docs/DEVICE_NOTES.md#exit-game-github-36
+**SteamVR dashboard at game start:** launch.sh's `_dashboard_worker` hides the dashboard via `SteamClient.OpenVR.VROverlay` (agent `steam_js`) from the first FrameBridge `new layer:` line (120 s, ≤10 times, stops after `toggle_dashboard_action`); log `<base>/dashboard.log`, opt out `FRAMEPORT_KEEP_DASHBOARD=1`. → docs/DEVICE_NOTES.md#steamvr-dashboard-at-game-start
+**Space warp / ITR2:** OVRPort's dispatcher offers XR_FB_space_warp itself (`patch_disable_space_warp` doesn't reach UE5) → FrameBridge `hide_space_warp` (per game, off; suggested for UE5 + OVRPlugin). `equirect_emul` switches itself off on Vulkan. → docs/DEVICE_NOTES.md#space-warp--itr2
+**PR #34 (Lucas-Mathieu):** `native/adapter/audio_metadata.h` keeps Meta XR Audio Wwise metadata alive (Batman: Arkham Shadow 1.4.1 smoke-bomb crash). Outside PRs: review source, rebuild `artifacts/` ourselves, merge locally. → docs/DEVICE_NOTES.md#pr-34-meta-xr-audio-metadata-batman
+**Heuristics eval (2026-10-04):** 19/44 recipes exact (superseded by the 2026-10-15 numbers under Heuristics). → docs/DEVICE_NOTES.md#heuristics-eval-2026-10-04
 **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).
+**Proton default:** the newest **stable** ARM64 Proton (`pick_proton`; owner's headset A/B); `pcvr.proton_tool` dropdown (Experimental = alias `proton-experimental`), `ensure_proton`, `proton_alternative_worth_trying`. → docs/DEVICE_NOTES.md#proton-default-stable-vs-experimental
+**USB cable link:** `usb0` is a USB NCM gadget (Developer Mode only); Frame 10.86.200.233, PC **10.86.200.234** (`frame/usb.py`); ~37 MB/s; `scripts/usb_autotest.py`, `frameport frame usb-check`; discovery prefers USB > hotspot > network (`discovery.dedupe`). → docs/DEVICE_NOTES.md#usb-cable-link
 **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,

-into 0 (`orr w2, wzr, #6` → `mov w2, #0` after the adrp/add of the "Oculus" literal; the string stays: it is also

-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).
-**SteamVR overlay apps (agent v75, 2026-10-10):** host OpenVR overlays (VRApplication_Overlay) are composited over Lepton (Quest) games on the Frame (probe checker seen over 4XVR in the headset view, `native/vroverlay_probe`); Windows ones register through Proton's vrclient too (Temporal Reality's Windows build created its overlays; fpsVR never reaches OpenVR under Proton). Detection `analysis/vroverlay.py` (bundled `.vrmanifest` with `is_dashboard_overlay`, else OpenVR + IVROverlay + self-registration markers, engine Other; Rift fingerprint `RIFT_ANALYSIS`), patch `pcvr.vr_overlay` (param autostart), Linux entry fields `vr_overlay`/`vr_overlay_autostart` (game page switch); agent `register_vr_overlay`/`unregister_vr_overlay`/`launch_vr_overlay` (IVRApplications via ctypes, live; manifest `<anchor>/frameport-overlay.vrmanifest`, the app's own key, binary = launch.sh). **SteamVR on the Frame reads only `binary_path_linux_arm`** (binary_path_linux alone is skipped). Overlay apps: no launch test, no Linux Steam-parent watchdog (`FRAMEPORT_OVERLAY`), not a "running game". A Steam overlay-app shortcut and a game shortcut run together. SteamVR's SetApplicationAutoLaunch didn't persist on the dev Frame (the watch never started by itself) → **agent v76: FramePort's own autostart**: the deployment's `overlay.autostart` is the source of truth; `ensure_host_fixes` (`ensure_overlay_service`) keeps the user service `frameport-vr-overlays.service` (`_vr_overlay_watch`, 5 s polls of the known vrserver's /proc stat) only while an overlay app has autostart on (register/unregister, uninstall, purge and the kill switch `~/.local/share/frameport/vr-overlays.disabled` / `FRAMEPORT_NO_OVERLAY_AUTOSTART` update it); a new vrserver (pid + start time, kept in `~/.cache/frameport-vr-overlays.json` across agent updates) → child `_vr_overlay_round`: wait for IVRApplications, 15 s grace, `launch_vr_overlay` for apps not running (folder process or GetApplicationProcessId); log `~/.local/share/frameport/vr-overlays.log`. Dev Frame: adopted the running vrserver, skipped the already running watch; a start after a real SteamVR start/boot is not yet seen. Details: docs/FRAME_RUNTIME.md "Overlay apps".
-**Vader's leak solved / AC Nexus flips (2026-10-14):** Vader Immortal leaves GL errors pending on its context; SteamVR's GL interop (`openxr_graphics_gl_openvr.cpp`, `xrclient_<pkg>.txt` in Steam's logs: `SXR_GL_CHECK: error:0x502 ... glGenTextures`) takes the stale error as its own failure once, and from then on `CVRCompositorSharedTextures::BeginCommandBuffer` allocates a command buffer every frame (perf page-fault stacks; ~430 renderD128 mappings + 22 MB/s). Adapter `gl_error_clear` (GLES, catalog on for Vader ep1-3) clears them before xrCreateSwapchain/xrBeginFrame/xrEndFrame: flat memory, no SXR_GL_CHECK (headless). The per-game `xrclient_<pkg>.txt` logs are worth reading for runtime errors. The Frame's runtime caps swapchains per session (XR_ERROR_LIMIT_REACHED from ~15; AC Nexus asks for more): flip emulation now turns quads upright in place (scratch VkImage, once per acquire; transfer usage added to single-layer colour swapchains) instead of a shadow swapchain per quad, which ran into the cap (#138). Headless sessions don't draw AC Nexus's panels (adapter `flip_dump` saves before/after images of flipped quads, for headset runs).
-**Unreal's self-restart (agent v90, 2026-10-13):** UE 4.21+ restarts the app once after its first-run shader
-precompile ("optimizing" screen; `r.ProgramBinaryCache.RestartAndroidAfterPrecompile`): it starts its own LAUNCHER
-activity and calls System.exit(0); Lepton ends the container with the first process (the restarted one with it).
-Skipping `AndroidThunkJava_RestartApplication` or the cvar = 0 (accepted via UE4CommandLine.txt `-ini:`) left Sports
-Scramble on that level for good. launch.sh (RESTART_BLOCK, `upgrade_launchers` adds it) starts Lepton once more when
-`_restart_requested` sees the app's own LAUNCHER start (system log, uid >= 10000) <= 5 s before its exit; first run
-kept as `launch-before-restart.log`; `FRAMEPORT_NO_RESTART=1` off. Owner-verified with Sports Scramble's first start (2026-10-13).
-**xrWaitFrame runs ahead (Journey of the Gods, 2026-10-14, owner-verified):** with real frames (headset on) the
-Frame's runtime sometimes returns from xrWaitFrame at once with a display time less than one refresh after the frame
-just submitted, and then rejects the second submission for that refresh (`VRCompositorError_AlreadySubmitted` in
-Steam's `logs/xrclient_<pkg>.txt`; FrameBridge pacing above the display rate). VrApi games that render faster than
-the display ran ahead (~120 submits/s at 90 Hz) and the scene slid and snapped back. The VrApi bridge re-waits when
-the new display time is under half a period after the last submitted one (`pacing 2s:` counters). Headless runs only
-submit empty frames and never show it. Lepton's logcat mirror also missed the whole verifying session (launch.log =
-Lepton's own lines only): the keeper now catches a silent mirror too (agent v91).
-**Lepton's logcat mirror dies (agent v67, 2026-10-09; v91 2026-10-14):** Lepton's mirror (`podman exec -it <container> logcat -v threadtime,color`) fails three ways: `logcat: Unexpected EOF!` right after the game starts, `Logcat read failure`, or running and writing nothing at all (Lepton 3.0.5: seen twice on 2026-10-14, once in the owner's session, once headless). launch.sh's `_logcat_keeper` reads `podman exec <container> logcat -v threadtime -T <epoch>` itself into launch.log after a failure line or 20 s without a logcat line (from the launcher's start when the mirror never wrote, else from just before its last line), restarts it from where it ended (≤5), stops it when Lepton's coloured lines come back, sets the container's log buffer to 16 MiB (`logcat -G`), and logs every decision to `<base>/logcat-keeper.log`. Checked on the dev Frame: a mirror killed mid-game (hand-over without a gap) and a silent mirror (the whole session recovered).
-**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).

-**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).

-Agent v74: a reporter's hang came ~10 s after the last new module, so the culprit wasn't among the newest written →
-with an index naming modules, `shader_dumps` sends every module of the index's **newest session** (after the last

-**Steam Input gamepad for 2D apps (GitHub #162, agent v72, 2026-10-10):** Lepton's Android only has the Wayland seat's `wayland_touch/keyboard/pointer`.

Lepton's container root (system_server too) = steamos (`keep-id:uid=0`), so a bind-mounted `/dev/input/eventN` opens. Opt-in `device.steam_gamepad` (vr_kind none; suggested for `android.hardware.gamepad`/`LEANBACK_LAUNCHER`, analysis `gamepad`, ANALYSIS_VERSION 9): deployment.json `steam_gamepad` → launcher `GAMEPAD_LINE` (after the codec line: exports FRAMEPORT_GAMEPAD + LEPTON_ENV_SDL_GAMECONTROLLER_ALLOW_STEAM_VIRTUAL_GAMEPAD, puts `agent/bin` first on PATH) → `PODMAN_WRAPPER` (written by ensure_host_fixes; non-`run` calls go straight on; `run` imports the agent's `podman_run_args`; hands on to the next Podman after its own PATH entry with itself removed from PATH, so it chains to the codec wrapper either way round) adds the pads + `Vendor_28de_Product_<pid>.kl` (Xbox 360 layout). Verified headless with a uinput stand-in pad (Stremio's container: EventHub `classes=0x80000141`, our key layout, KeyEvent BUTTON_A dispatched); with Steam's real pad and a game: not yet.

-**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).
-Demo link: the homepage's example button = `deeplink.DEMO_MANIFEST` (https://frameport.app/demo/cool-game.json, published
-from site/public/demo/); every form (https button page, frameport://, framedrop://, pasted) → `InstallRequest.demo`,
-no network (fetch_manifest returns `demo_manifest()`, download refuses), `link_dialog.show_demo` (Install =
-`easter.demo_install`: Cool Game's cover out of the portal; eggs off → "Nice, it works!"), CLI just says so.

+## GitHub triage (issues / discussions / PRs)
+GitHub identity + credentials are maintainer-local (`CLAUDE.local.md`): check `gh api user --jq .login` before any
+GitHub write. **The owner approves before posting, labelling or closing anything.** Reply style: "I"/neutral, never
+we/our/us; never mention agent version numbers or internal tool versions; show the owner every draft in full with a
+short recap of the thread so far; read **all** comments on a thread first (a later one often has the zip or the answer).
+- **Every triage also sweeps for unanswered comments**, not just new threads: open AND recently closed issues, PRs
+  (incl. merged/closed ones) and discussions (top-level comments and their replies) whose latest comment isn't the
+  maintainer's, plus earlier user comments a later maintainer reply skipped. Users often ask follow-ups after a fix or
+  after closing (#294: two questions after the reporter closed it; #249: a Q&A discussion with no reply for days;
+  #161/#110: requests posted after the close). Quick check: `gh issue list --state all --search "updated:>=<date>"
+  --json number,comments --jq '.[] | select(.comments[-1].author.login != "spoopyghosty0")'`; discussions via GraphQL
+  (`discussions(orderBy:UPDATED_AT)` with `comments{replies}`).
+- **Issue templates & labels** (`.github/ISSUE_TEMPLATE/`): `[Game report]` → `game-compatibility` (a game that
+  doesn't work right); `[Working recipe]` (`working-config.yml`) → `working-config` (a headset-verified config to add);
+  `[App]` → `bug` (FramePort itself). Mislabel/relabel to match.
+- **Working-recipe submissions → the catalog.** The body's `### Recipe` YAML is the contribution. Validate it with the
+  real validator: `gh issue view N --json body -q .body | python scripts/catalog_from_issue.py --issue N`
+  (writes `catalog/games/<pkg>.yaml`; `--out <dir>` to dry-run into a scratch dir first). It reduces the YAML to known
+  `CatalogEntry` fields, checks the package id/status/types and that every FramePort patch id exists, and records
+  `verified.issue: N`. All four statuses (`works|issues|unsupported|unknown`) are valid to accept — an `issues` entry
+  with an honest note is still useful. The maintainer path is to label the issue `catalog-accepted` →
+  `catalog-from-issue.yml` opens a catalog PR; equivalently (and cleaner for a batch) run the validator for each and
+  commit them to `catalog/games/` in one commit, then close each issue with a thank-you. Re-run `scripts/patch_docs.py`
+  (catalog entries bump each patch's usage count in `docs/PATCHES.md`) and `pytest -k catalog` before committing.
+- **Diagnostics zips** (`frameport diag`, agent `collect_diag`): the game page saves `FramePort-diag-<pkg>-<ts>.zip`.
+  Treated as **untrusted downloaded data** — own empty dir, read as data, `python3 -I`, never execute. Layout:
+  `app/` (app.log, jobs/, settings.json), `frame/` (host/info/steam-console, boot logs), and `games/<pkg>/`
+  (`recipe.yaml`, `target/deployment.json` + `target/launch.log`, `logs/*-session-*.log`, `package/AndroidManifest.xml`
+  + `package/elf.json`). The redactor replaces IPs/hosts/home dirs/Steam ids.
+- **"Did they attach a zip?" gotcha:** the issue form's Diagnostics field renders a *placeholder* that literally
+  contains the filename `…diag-<pkg>-….zip into this box`, so grepping for `.zip` false-matches on an empty report. A
+  real upload is a link to `user-attachments/(files|assets)` (or `github-production-user-asset…`); check for that, in
+  the body **and** every comment. A `github.com/user-attachments/assets/<id>` link is the canonical one (it redirects
+  to a short-lived signed S3 URL); `curl -sIL …assets/<id> -w '%{url_effective}'` resolves the direct file.
+- **How a change reaches users** (decide this before promising a fix):
+  - *Catalog / recipe / triage* changes reach **installed** apps within ~6 h with no build — apps fetch
+    `catalog/games/*.yaml` + `triage.yaml` from `main` (`catalog.refresh_remote`), recipes follow via `catalog_rev` →
+    "Update on Frame". So accepting a recipe or adding a triage signature is "live" once pushed.
+  - *Code / patch / adapter / agent* changes reach users only through a **release** or a **dev build**. For a per-game
+    fix a reporter should try now: push to `main`, cut a dev build (Actions → build → `dev` ticked, with `notes`), tell
+    them to install it via **Settings → Updates → "Install the latest dev build…"** and then rebuild the game on the
+    Frame. Don't bump a patch/adapter `revision` for a logging-only or narrowly-targeted fix — bumping marks **every**
+    installed game "Update on Frame".
+- **Verifying a device fix without the headset:** many runtime failures (e.g. an `xrEndFrame` layer rejection) reproduce
+  in a **headless** launch test on the dev Frame, so the fix can be developed and confirmed at the frame-acceptance
+  level there; only the *visual* result needs the headset (hand the built dev build to the reporter, or the owner, for
+  that). `frameport settings <pkg> <key>=<value>` toggles adapter settings (e.g. `layer_debug=1`) live, no rebuild.
+  To reproduce a reporter's exact build, grab their APK from its upstream source (e.g. the linked GitHub release), scan
+  → build → install → test in an isolated `FRAMEPORT_HOME` (see "Dev commands" / the Frame-busy rules).
+

+# Announcements
+
+`current.md` is the one announcement FramePort shows as a pop-up in the app. Edit it on `main`: the app reads it
+from GitHub `main` (raw.githubusercontent.com) at most every 6 hours, so a push reaches everyone without a release.
+
+## Who sees it
+
+- **Only people who already used FramePort before the announcement's `date`.** A new install never shows one, and
+  nor does an announcement published before FramePort was installed.
+- **Once.** Closing it in any way (the X, a click outside it, Escape, or its button) dismisses it for good. The app
+  remembers dismissals in its settings (`announce.dismissed`).
+- **A new announcement = a new `id`.** Fixing a typo with the same `id` doesn't show it again to anyone who closed it.
+  A new `id` shows to everyone who used FramePort before its `date`, whether they closed the earlier one or not.
+
+## The file
+
+```markdown
+---
+active: true                    # false = nothing is shown (the fields are still checked)
+id: meetup-2026-11             # letters, digits, . _ -  — change it for every new announcement
+title: Steam Frame meetup on Discord  # required
+date: 2026-11-02T18:00:00Z      # required: when it was published (UTC; a bare date = midnight UTC)
+image: announcements/meetup.png # optional: a file in this folder, or an https URL (PNG, JPEG, WebP, GIF; ≤ 5 MiB)
+image_alt: The meetup poster    # optional: what the picture shows (screen readers)
+button: Join the meetup         # optional: an action button, with url
+url: https://example.com/meetup
+expires: 2026-11-30             # optional: not shown after this day (UTC, inclusive)
+---
+The body, in Markdown: **bold**, *italic*, `code`, [links](https://frameport.app/), lists, headings.
+```
+
+The body is Markdown (no HTML). A `date` in the future works as a schedule: nobody sees it before then.
+
+Images look best at about 2:1 (e.g. 1200×600). The pop-up is 600 px wide and shows between 140 and 320 px of the
+picture's height.
+
+`pytest tests/test_announcements.py` checks this file, so a broken announcement fails CI instead of silently showing
+nothing.
+
+To turn announcements off for testing: `FRAMEPORT_NO_ANNOUNCEMENTS=1`.

+## a32 bridge: games, lessons, debugging aids, profiling
+
+Learned: Unity 2019 contexts
+have no EGLConfig (EGL_KHR_no_config_context: the VrApi bridge takes the window's or an RGBA8 ES3 config); Unity's
+floor origin = vrapi_SetTrackingSpace(1) (the VrApi bridge now honours LOCAL_FLOOR/STAGE); mapped GL buffers are
+per buffer object (a per-target guest copy leaked ~10 MB/s and garbled vertices); the guest runtime's own scudo
+names its maps `[anon:scudo:*]` below 4 GiB (watch them for guest leaks). The Go controller = the right Frame
+controller (stick = touchpad touch, sideways > 0.6 or press = click). Gunjack (CCP, UE 4.10 NativeActivity, Gear VR,
+2026-10-10): needed the native_app_glue imports (ALooper/AInputQueue/AConfiguration/AAsset*, imports.txt), an arm64
+libvrapi.so for Java's System.loadLibrary("vrapi") and MOUNTED under OVP_HEADLESS_TEST; it then loads its map and
+quit on purpose: AndroidMain compares AndroidThunkCpp_GetSignature() with an obfuscated copy. **Works since
+2026-10-11 (owner-verified in the headset):** GameActivity.AndroidThunkJava_GetSignature() = Base64.DEFAULT(SHA-1(
+signing certificate DER)) (jadx); `a32_bridge.original_signature` computes it from the original APK's
+META-INF/*.RSA|DSA|EC, `convert()` stores it as `assets/fp_a32_signature.txt` for libUE4.so games, the bridge loads
+it at activity creation (native_activity.c) and jni.c answers Call*Method on the method ID of
+`AndroidThunkJava_GetSignature()Ljava/lang/String;` with it. After loading, Unreal leaves VR mode and enters it again on
+the same GL context; a second OpenXR session there aborted in vrclient (CSharedSemaphoreLinux::WaitFromGPU from the GL
+binding's PreBeginFrame, also with OVP_HEADLESS_TEST) → the VrApi bridge keeps a running GLES session across
+LeaveVrMode and reuses it for an EnterVrMode with the same context (upstream-patches/runtime.cpp.patch).
+Debugging aids added: A32_BREAK=<guest addr>[,..] (stack of the first hits; guest libs load at fixed addresses, e.g.
+libUE4 0xf25d5000), A32_STRACE in bridge mode = path/exit calls to logcat, activity lifecycle + LeaveVrMode caller
+logs. Lepton's logcat mirror often dies for these games: read `podman exec <container> logcat` instead. Gunjack input
+(2026-10-11): it imports no vrapi input functions and reads the Gear VR touchpad/back as AInputEvents from its
+AInputQueue (native_app_glue), so dispatchKeyEvent never reached it (no control at all) → input.c queues synthetic
+events there (ALooper_poll* return the queue's ident while one waits; AInputQueue_getEvent/finishEvent and the
+AInputEvent/AKeyEvent/AMotionEvent getters are hand-written "!" imports that know them; touch positions scaled to the
+window size). Same mapping as AFFECTED: trigger = hold touchpad, A = tap, right stick = swipe, B = back; for NativeActivity games the stick's up/down = swipe forward/back (touchpad X: Gunjack's OnFlick = reload at ~0°, special weapon at ~180°). Not yet
+headset-verified. Quest builds on the bridge (2026-10-13, Sports Scramble = a 32-bit Santa Cruz build,
+UE 4.21 + OVRPlugin on VrApi 1.21): manifest requires `android.hardware.vr.headtracking` version 1
+(`detect.requires_6dof`, headset "quest", ANALYSIS_VERSION 16) → convert writes `assets/fp_a32_headset.txt`
+= "quest" → vrapi.c `quest_touch` (read in vrapi_Initialize via the activity's AssetManager; A32_TOUCH=1/0
+overrides) passes the 64-bit bridge's Touch controllers through (enumerate/caps/state/tracking/haptics, struct
+tails per VrApi minor) and starts no synthetic input. It also needed AAsset_getBuffer (guest copy, freed in
+AAsset_close), AKeyEvent_getFlags and the other AConfiguration getters. Headset (owner, 2026-10-13): plays,
+both controllers work. Recenter (holding the Frame's menu button) turned VrApi games ~90-120 degrees aside: the bridge's app space is LOCAL + the start yaw and the runtime moves LOCAL to the head → the bridge now takes the origin from the head again on XR_TYPE_EVENT_DATA_REFERENCE_SPACE_CHANGE_PENDING (LOCAL) and on vrapi_RecenterPose (owner-verified with Gunjack, 2026-10-13). Next: the other 32-bit catalog games (Journey of the Gods, Shadow Point: still "unsupported" until
+tested), translator speed. Profiled on the Frame
+(2026-10-12, `A32_PERFMAP` + perf): FPCR switches are negligible (8 of 86k samples); the cost was the run loop
+(a mutex + hash-chain walk on every dispatch, a contended counter, inline-lookup slots never refilled: Gunjack
+~45 % of its CPU) and `jit_invalidate` scanning every block on each Mono `cacheflush` (72 % of Spunky Dungeon's
+main thread). Now lock-free lookups, ltab refill, per-thread flags, per-page block lists: Gunjack's dispatcher
+23.6 % -> 1.6 %, CPU in the same phase about -55 %, still 72 fps.
+
+## Upload speed
+
+**Upload speed (measured 2026-09-29):** via the home router (PC Wi-Fi → router → Frame wlan0) only 15-18 MB/s, the
+same for paramiko, OpenSSH and 4 parallel streams, so the network path is the limit, not the SSH code. Direct to the
+Frame's hotspot (`wlanap` 10.35.78.1; the owner's PC has Valve's USB Wi-Fi dongle on it) 83 MB/s OpenSSH / 97 MB/s
+paramiko; reading dumps from D: via WSL drvfs is then the cap (~82 MB/s). `Frame.fast_link()` (installer
+`transfer_link`, uploads ≥64 MiB) uses usb0 > wlanap when reachable **and** the host key matches the paired Frame.
+
+## Revive under Proton arm64 (Lone Echo)
+
+**Revive under Proton arm64 (Lone Echo, 2026-09-29):** Revive's Detours hooks (LoadLibraryW/ExW, OpenEventW, the
+signature check) don't take effect: Wine's kernelbase is ARM64EC. The LibOVR shim in the game then does a plain
+`LoadLibrary("LibOVRRT64_1.dll")` search (exe dir, cwd, system32, windows, PATH — no registry, `OculusBase` or
+`LIBOVR_DLL_DIR` used by this build) → `Failed to initialize Oculus API (-3001)` (= Lies Beneath's "Unable to load
+LibOVRRT DLL"). A symlink `pfx/drive_c/windows/system32/LibOVRRT64_1.dll -> <base>/revive/LibReviveXR64.dll` (Wine
+maps a symlink to the already-loaded module) gets past it to **-3021 = ovrError_LibSignCheck**: the shim only accepts
+an Oculus-signed runtime. Next step (not done): make the runtime check pass without Detours, e.g. an injected helper
+that patches the game's import table (IAT) for LoadLibrary*/WinVerifyTrust, or a prefix-level override. This is
+runtime interop (what Revive does), not the Platform SDK licence check (which FramePort never touches).
+Uninstall (Quest, saves kept) used to leave `deployment.json` → still "installed"; fixed (agent v16).
+
+
+## OVRPort 1.2.5
+
+**OVRPort 1.2.5 (2026-10-01, the fork's first release; CLI-only):** same commands (`patches [--json]`, `patch`, `help`,
+`install`), but `patch` rejects unknown/duplicate args, unknown patch ids and an empty `--patches=`
+(`tools/overport.patch` refuses empty lists). After patching it adds `libovrplatformcompat.so` itself when the platform
+loader lacks `ovrMessageType_ToString` (our `frame.ovrplatformcompat` then skips: same library). New patches (all off;
+`patches/overport.py`): `patch_ac_nexus_no_appsw_72/_90` (AC Nexus build 207706 only, exclusive),
+`patch_disable_meta_xr_audio_telemetry` (x86_64 emulators: hidden), `patch_vrapi_openxr` = OVRPort's VrApi adapter =
+the **unpatched** upstream of our `frame.vrapi_bridge` (`native/vrapi` unchanged since our 5e7df52), only usable with an
+experimental CLI built with `-PwithVrApi=true` (stable jars list it but fail). The owner prefers OVRPort's fixes over
+ours where they work as well (less to maintain): compare in the headset before switching a default.
+`frameport install <pkg> --apk <file>` installs a specific (test) build signed with the game's key.
+Headset results (2026-10-02, `PATCHED/_test-ovrport-1.2.5/TESTING.md`): OVRPort's own VrApi translator fails on the
+Frame (Climb 2: requests VkFormat 37 → crash; POTW: no GLES path, missing `vrapi_GetTextureSwapChainHandle`) → keep
+`frame.vrapi_bridge`; those two changes are upstream candidates. 1.2.5 builds (its platform compat, new permissions)
+work. AC Nexus: `patch_ac_nexus_no_appsw_90` is the catalog default (owner preferred 90 Hz); `STRICT` patches are only
+taken from a catalog recipe where `applies()` holds (the AC Nexus ones need build MAIN.450412.207706.final, else the
+whole overport run fails).
+
+
+## Steam Frame controller models
+
+**Steam Frame controller models (2026-09-30, not yet seen in a game):** adapter setting `controller_models`
+(`native/adapter/render_model.c`) emulates XR_FB_render_model and serves `files/framebridge/controller_{left,right}.glb`;
+agent v20 (`install_controller_models`, command `controller_models`) converts the Frame's SteamVR render models
+(folder name matching "frame" + left/right, OBJ+PNG, `openxr_grip` component → grip space) at finalize/set_settings.
+Valve's models are never committed or copied off the Frame. Only games that use Meta's runtime controller models
+benefit (manifest `RENDER_MODEL` permission/feature → suggested); **none of the 34 catalog games do** (they ship their
+own meshes: that would need per-game asset replacement). Model discovery and conversion
+checked on the device 2026-09-30: `/opt/steamvr/drivers/frame_controller/resources/rendermodels/frame_controller_{left,right}`
+(component OBJs in model space = the whole `<name>.obj`, one `_color.png` 2048² near-black, `openxr_grip` rotates about
+X only; hidden-by-default components like `status` are skipped) → ~2 MB glb each, ~1 s. Not yet seen in a game (none
+of the installed builds has the new adapter, and none requests runtime models), so whether Meta's SDK attaches runtime models at the grip pose is unverified.
+
+## Crash backtraces, Fossilize, swapchain limit, cylinder and equirect layers
+
+**Crash backtraces (2026-09-30):** Lepton writes tombstones only to `lepton-logcats/steamlaunch-<appid>/logcat-crash.log` (after "Dumping logcat"), not launch.log; agent v23 launch tests wait for it and return `crash_log`, triage gets it via `triage(..., crash=)` (not pid-filtered: tombstones come from crash_dump's pid). The guest is `userdebug` (`ro.debuggable=1`), so Lepton's Fossilize layer loads into every app whatever the APK's debuggable flag; it has no off switch. Fossilize crashed Deadpool VR on uninitialized attachment-reference pNexts (several, in FVulkanRenderPass and the render-target layout) → `frame.vk_sanitize` = `native/vkshim` (engine's `dlopen("libvulkan.so")` string → `libfp_vk.so`, wraps vkCreateRenderPass2/KHR, drops unreadable/wrong-sType pNexts; verified: game runs). overport's dispatcher aborts on swapchains > 4096 px (`cmp wN,#4096` in xrCreateSwapchain) → `frame.swapchain_limit` (verified with 4XVR, 7680×3840 accepted by the runtime). Both are default-on (parity classifies their rewrites as
+"expected"; library migration `quest_binary_fixes_v2`). The adapter shows cylinder layers (4XVR's movie screen) as ~15° quad strips (`cylinder_strips`, setting
+`cylinder_strips`); the runtime composites them at full resolution. Equirect (360°) layers are dropped: drawing
+them ourselves (GLES renderer in xrEndFrame: stutter, never showed 4XVR's VR video; Vulkan renderer: hung the
+Frame's GPU in AC Nexus; reading the newest *released* image broke 4XVR's theatre) was removed again on the owner's
+request — don't retry without a new approach. Converted layers must count as "swapped" or the original layer list
+is submitted (runtime returns -2 for every frame). A focus debounce (hiding the Frame's brief
+FOCUSED→VISIBLE→SYNCHRONIZED dips, which make 4XVR recenter) was also removed: AC Nexus stayed black with it (it
+hid 521 ms focus changes at start). The new approach (below) is per-game, off the app's render thread, GLES-only.
+
+
+## 360° layers / 4XVR
+
+**360° layers / 4XVR (2026-09-30):** the Frame's Android SteamVR runtime (`/opt/steamvr/bin/androidarm64/vrclient.so`,
+mounted in Lepton as `/data/steamvr/runtime`) only composites quad + projection layers (cube/cylinder/equirect(2)
+are enum names only) — nothing to unlock. Per-game adapter settings (off by default, hooks installed only when on):
+`equirect_emul` (GLES only: a worker thread with a shared EGL context converts each 360° image to a cube map when it
+changes and draws one adapter projection layer from it for every frame with exactly that frame's views (the app's own
+projection views, else xrLocateViews at displayTime); xrEndFrame waits ≤6 ms for the worker's CPU submit, never the
+GPU. Learned in the headset: quads can't be a background (the Frame draws quad layers above all projection layers
+whatever the order: hid 4XVR's balcony/controllers), and the Frame doesn't reproject a projection layer from its own
+pose (images drawn only after head turns, or ahead from xrWaitFrame and sometimes late, wobbled);
+`equirect_flip/face/res/fps/stereo`), `stable_local`, `focus_hold` (only after 3 s FOCUSED, dips <600 ms),
+`aim_pitch/aim_yaw/aim_forward`, `refresh_rate`, `layer_debug` (diagnostics); focus_hold is default-on since 2026-10-05. 4XVR re-creates LOCAL spaces every 2–4 s
+(menu recentring suspect); its theatres are baked 7680×3840 equirect2 images (`assets/100.png` …). Test 360° videos
+(NASA, public domain) are in the Frame's ~/Videos; copies in `~/Downloads/frameport-360`. 4XVR's "Internal Storage"
+lists its own `/sdcard/4XPlayer`, not Movies: agent v25 `link_media` hard-links sent files into an app's own top-level
+folder (`app_media_dirs`), `frameport frame send --app <pkg>`, GUI game page "Add videos" (players) / "Add videos &
+files…". A 4XVR webm stereo swapchain was refused with XR_ERROR_LIMIT_REACHED (-10) → right eye grey; our projection
+swapchain was halved (1536/eye) in case memory is the limit (unverified). Frame data snapshot
+(SteamVR runtimes, Lepton scripts, logs; never commit Valve binaries): `~/frameport-research/frame-data-2026-09-30/`.
+Not yet verified in the headset.
+
+
+## Companion apps / intents (Stremio + 4XVR)
+
+**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 (Stremio VR)
+
+**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)
+
+**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`).
+
+## Round 2 of reports, headset rounds 2-3 (2026-10-04)
+
+**Round 2 of reports (2026-10-04):** VR4's campaign hang = one fragment shader reading an uninitialized loop counter

+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
+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`); lost again (agent v89): Steam
+ignores FramePort's entries on that Frame, so `add_devkit_entry` adds the devkit entry instead (`added` gets `via:
+devkit`) and only reports an error if that fails too. 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). Godot 4.2-4.4 (Kotlin `as ClipboardManager`,
+GitHub #134 EndoparasiticVR) → `frame.godot_clipboard` (nops the `Intrinsics.checkNotNull` before that check-cast; Godot's
+clipboard methods return at once; analysis `godot_clipboard`, ANALYSIS_VERSION 10; checked on real godot-lib/templates
+4.2.2-4.4.1, not on the device; 4.1 and 4.5+ don't throw). 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): surface swapchains, save-folder permissions
+
+**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 and the devkit fallback (GitHub #21/#30/#41/#42)
+
+**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)
+
+**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
+
+**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
+
+**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: Meta XR Audio metadata (Batman)
+
+**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)
+
+**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).
+
+## Proton default (stable vs Experimental)
+
+**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
+
+**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).
+
+## Start activity / QuestCraft / ITR2 pop-in
+
+**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
+
+**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: PowerWash Simulator, The Room VR
+
+**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)
+
+**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 (Accounting+, BattleSisters)
+
+**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,

+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

+`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).
+
+## SteamVR overlay apps
+
+**SteamVR overlay apps (agent v75, 2026-10-10):** host OpenVR overlays (VRApplication_Overlay) are composited over Lepton (Quest) games on the Frame (probe checker seen over 4XVR in the headset view, `native/vroverlay_probe`); Windows ones register through Proton's vrclient too (Temporal Reality's Windows build created its overlays; fpsVR never reaches OpenVR under Proton). Detection `analysis/vroverlay.py` (bundled `.vrmanifest` with `is_dashboard_overlay`, else OpenVR + IVROverlay + self-registration markers, engine Other; Rift fingerprint `RIFT_ANALYSIS`), patch `pcvr.vr_overlay` (param autostart), Linux entry fields `vr_overlay`/`vr_overlay_autostart` (game page switch); agent `register_vr_overlay`/`unregister_vr_overlay`/`launch_vr_overlay` (IVRApplications via ctypes, live; manifest `<anchor>/frameport-overlay.vrmanifest`, the app's own key, binary = launch.sh). **SteamVR on the Frame reads only `binary_path_linux_arm`** (binary_path_linux alone is skipped). Overlay apps: no launch test, no Linux Steam-parent watchdog (`FRAMEPORT_OVERLAY`), not a "running game". A Steam overlay-app shortcut and a game shortcut run together. SteamVR's SetApplicationAutoLaunch didn't persist on the dev Frame (the watch never started by itself) → **agent v76: FramePort's own autostart**: the deployment's `overlay.autostart` is the source of truth; `ensure_host_fixes` (`ensure_overlay_service`) keeps the user service `frameport-vr-overlays.service` (`_vr_overlay_watch`, 5 s polls of the known vrserver's /proc stat) only while an overlay app has autostart on (register/unregister, uninstall, purge and the kill switch `~/.local/share/frameport/vr-overlays.disabled` / `FRAMEPORT_NO_OVERLAY_AUTOSTART` update it); a new vrserver (pid + start time, kept in `~/.cache/frameport-vr-overlays.json` across agent updates) → child `_vr_overlay_round`: wait for IVRApplications, 15 s grace, `launch_vr_overlay` for apps not running (folder process or GetApplicationProcessId); log `~/.local/share/frameport/vr-overlays.log`. Dev Frame: adopted the running vrserver, skipped the already running watch; a start after a real SteamVR start/boot is not yet seen. Details: docs/FRAME_RUNTIME.md "Overlay apps".
+
+## Vader's leak solved / AC Nexus flips
+
+**Vader's leak solved / AC Nexus flips (2026-10-14):** Vader Immortal leaves GL errors pending on its context; SteamVR's GL interop (`openxr_graphics_gl_openvr.cpp`, `xrclient_<pkg>.txt` in Steam's logs: `SXR_GL_CHECK: error:0x502 ... glGenTextures`) takes the stale error as its own failure once, and from then on `CVRCompositorSharedTextures::BeginCommandBuffer` allocates a command buffer every frame (perf page-fault stacks; ~430 renderD128 mappings + 22 MB/s). Adapter `gl_error_clear` (GLES, catalog on for Vader ep1-3) clears them before xrCreateSwapchain/xrBeginFrame/xrEndFrame: flat memory, no SXR_GL_CHECK (headless). The per-game `xrclient_<pkg>.txt` logs are worth reading for runtime errors. The Frame's runtime caps swapchains per session (XR_ERROR_LIMIT_REACHED from ~15; AC Nexus asks for more): flip emulation now turns quads upright in place (scratch VkImage, once per acquire; transfer usage added to single-layer colour swapchains) instead of a shadow swapchain per quad, which ran into the cap (#138). Headless sessions don't draw AC Nexus's panels (adapter `flip_dump` saves before/after images of flipped quads, for headset runs).
+
+## Unreal's self-restart
+
+**Unreal's self-restart (agent v90, 2026-10-13):** UE 4.21+ restarts the app once after its first-run shader
+precompile ("optimizing" screen; `r.ProgramBinaryCache.RestartAndroidAfterPrecompile`): it starts its own LAUNCHER
+activity and calls System.exit(0); Lepton ends the container with the first process (the restarted one with it).
+Skipping `AndroidThunkJava_RestartApplication` or the cvar = 0 (accepted via UE4CommandLine.txt `-ini:`) left Sports
+Scramble on that level for good. launch.sh (RESTART_BLOCK, `upgrade_launchers` adds it) starts Lepton once more when
+`_restart_requested` sees the app's own LAUNCHER start (system log, uid >= 10000) <= 5 s before its exit; first run
+kept as `launch-before-restart.log`; `FRAMEPORT_NO_RESTART=1` off. Owner-verified with Sports Scramble's first start (2026-10-13).
+
+## xrWaitFrame runs ahead (Journey of the Gods)
+
+**xrWaitFrame runs ahead (Journey of the Gods, 2026-10-14, owner-verified):** with real frames (headset on) the
+Frame's runtime sometimes returns from xrWaitFrame at once with a display time less than one refresh after the frame
+just submitted, and then rejects the second submission for that refresh (`VRCompositorError_AlreadySubmitted` in
+Steam's `logs/xrclient_<pkg>.txt`; FrameBridge pacing above the display rate). VrApi games that render faster than
+the display ran ahead (~120 submits/s at 90 Hz) and the scene slid and snapped back. The VrApi bridge re-waits when
+the new display time is under half a period after the last submitted one (`pacing 2s:` counters). Headless runs only
+submit empty frames and never show it. Lepton's logcat mirror also missed the whole verifying session (launch.log =
+Lepton's own lines only): the keeper now catches a silent mirror too (agent v91).
+
+## Lepton's logcat mirror dies
+
+**Lepton's logcat mirror dies (agent v67, 2026-10-09; v91 2026-10-14):** Lepton's mirror (`podman exec -it <container> logcat -v threadtime,color`) fails three ways: `logcat: Unexpected EOF!` right after the game starts, `Logcat read failure`, or running and writing nothing at all (Lepton 3.0.5: seen twice on 2026-10-14, once in the owner's session, once headless). launch.sh's `_logcat_keeper` reads `podman exec <container> logcat -v threadtime -T <epoch>` itself into launch.log after a failure line or 20 s without a logcat line (from the launcher's start when the mirror never wrote, else from just before its last line), restarts it from where it ended (≤5), stops it when Lepton's coloured lines come back, sets the container's log buffer to 16 MiB (`logcat -G`), and logs every decision to `<base>/logcat-keeper.log`. Checked on the dev Frame: a mirror killed mid-game (hand-over without a gap) and a silent mirror (the whole session recovered).
+
+## Double launch
+
+**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)
+
+**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
+
+**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
+
+**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
+
+**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
+
+**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.
+
+## Hardware video decoding
+
+**Hardware video decoding (PR #96, PR #128 by Lucas-Mathieu, adapted 2026-10-10, agent v71):** `native/hevc` = one
+OMX plugin `OMX.frameport.{avc,hevc,vp9}.decoder` (FFmpeg v4l2m2m on Iris /dev/video-dec0, FFmpeg software decoders as
+fallback inside the component, Vulkan copy for big native surfaces). The connection installs it once per Frame
+(`ensure_video_codec` → agent `video_codec_status`/`install_video_codec`: `~/.local/share/frameport/video-codec/versions/
+<manifest sha>` + `current` symlink). A Frame keeps the same or a newer `revision` (no flip-flop between PCs) → **bump
+`revision` in native/hevc/build.py with every artifact change**; a failed install isn't retried during the connection.
+Per game: only launchers of games whose recipe has `frame.hw_video_decode` (install stage, no APK change; suggested
+from analysis `media_codec`, ANALYSIS_VERSION 8; deployment.json `hw_video_decode`) get the codec line → the Podman
+wrapper (native/hevc/podman.py) mounts the plugin into that container (merged media_codecs.xml in
+$XDG_RUNTIME_DIR/frameport-video). Off for every game: Settings → Installing (library `video.hw_decode` → agent
+`video_codec_switch` = video-codec/disabled); one game: `FRAMEPORT_NO_HW_VIDEO=1 %command%`. `upgrade_launchers`
+converts agent ≤70 launchers (Batman's `<base>/frameport-codec` → keeps the line, folder then removed). Batman: catalog
++ migration `batman_video_patches` (`frame.hw_video_decode` + hidden adapter setting `surface_native`). Iris: 8K
+refused (ENOMEM) while any other decoder session is open; SteamVR's vrlinkrunthread holds one ~12 s at game start →
+refused opens retry until 20 s after the plugin loaded (else 2 s), then software; VP9 7680x3840 never returned a
+picture → VP9 ≤4096x2304; hidden VP9 frames come back as empty capture buffers (bytesused 0, no LAST):
+FFmpeg's wrapper ended the EOS drain at the first one (two-pass VP9 lost its last ~25 frames) → build.py requeues
+them (codec revision 8; drain ends at LAST, or 1 s after a skipped empty buffer; dev Frame 2026-10-10: 600/600 =
+OMX.google.vp9 Y hashes). Rebuilds are deterministic (ext4 + NTFS path
+with spaces, two NDK copies → same; rev 8 141de01f…; PR #128's own sources → its 27a2d749…). Not yet run on the device.
+
+## Vulkan shader dump
+
+**Vulkan shader dump (GitHub #140, 2026-10-10):** adapter `vk_shader_dump=1` (Vulkan shim, `native/vkshim/shader_dump.h`;
+applies where vk_sanitize can: Unreal/Other arm64) writes each distinct SPIR-V module once to
+`files/fp_vk_shaders/<size>_<sha256>.spv` (tmp + rename) and one `index.txt` line per vkCreateShaderModule (`<seq> <ms>
+<unix ms> <name> new|known|again|failed`, O_APPEND) to find the module behind a GPU hang. Agent v72 `collect_diag`
+returns `shaders` (newest modules of fp_vk_shaders + fp_spirv, ≤4 MB each, base64) → bundle
+`games/<pkg>/target/shaders/`. Triage `gpu-hang` suggests both dumps; `triage.graphics_api` (FrameBridge's
+xrCreateSwapchain formats: <0x1000 Vulkan, else GL) keeps only the session's API's (`API_ONLY`). Host-tested only.
+Agent v74: a reporter's hang came ~10 s after the last new module, so the culprit wasn't among the newest written →
+with an index naming modules, `shader_dumps` sends every module of the index's **newest session** (after the last
+`# start`), deduplicated, last used first, each ≤4 MB, ≤30 MB in all (`session` = how many it names) + that session's
+index lines; no index (fp_spirv) = the old newest-by-mtime 4 MB. One JSON line (~40 MB base64) over the SSH channel
+is read whole by `Frame.agent` (fine at that size); `_Writer.fit` drops the least recently used modules last, after
+cutting logs, to stay under the 24 MB zip limit.
+
+## Unreal OBB check
+
+**Unreal OBB check (GitHub #159, 2026-10-10):** Epic's DownloaderActivity checks OBB name+size (OBBData), then with `bVerifyOBBOnStartUp=true` CRCs the whole OBB; its screens are invisible in Lepton (stuck at `Displayed …/.DownloaderActivity`, triage `unreal-obb-check-stuck`) → `frame.unreal_skip_obb_check` (analysis `unreal_verify_obb`, ANALYSIS_VERSION 11) flips the manifest boolean (`axml.set_meta_data_bool`); skips only the CRC pass. Host-tested only.
+
+## Issue round 2026-10-12
+
+**Issue round 2026-10-12 (agent v83):** Lepton pastes STEAM_COMPAT_DATA_PATH unquoted into `sh -c "ln -s …/internal/<pkg>
+/data/data/<pkg>"` (mounting.sh): a game on a card named "Steam Frame 512g" got no internal storage (no saves/prefs;
+Beyond Sandbox's EOS then looped `createKeychain→resetKeychain` forever, 1.85 GB log). Quest launchers with an unsafe
+path now `ln -sfn <base> ~/.local/share/frameport/lepton-paths/<pkg>` at every start and give Lepton that path
+(`app_dir_lines`/`set_app_dir`/`launcher_base`; upgrade_launchers converts; deployment.json keeps the real base).
+Verified on the device with a spaced copy of Stremio (old: the `ln` error; new: /data/data link, shared_prefs
+writable). `frame.eos_keychain_loop` (opt-in, triage `eos-keychain-loop`) returns from EOSSDK.resetKeychain. Wander
+0.3570 (Unity 6.5, Firebase, Gecko) ran out of bionic's 128 pthread keys → `frame.unity_tls_key_pool` (Klownicle's
+approach, #198: libunity's 4 key imports renamed `fp_tkey_*` via `elf.rename_imports`, `libfp_tkeys.so` pools
+destructor-less keys behind one real key); device: past Firestore, 72 fps. Cpp2IL releases can't read metadata v107
+(Unity 6.5) → `tools/cpp2il.py` falls back to the development CI build (nightly.link) on that error, and since #293 on any release failure (BattleTalent, Unity 2021.3: the release dies exit 134 in CsFileUtils.GetTypeName after making the folders, no .cs; `il2cpp._run` = non-zero exit or no .cs is unreadable; never with FRAMEPORT_CPP2IL; caches holding "every class missing" are re-run). Vermillion's canvas
+is an OVROverlay quad (drawn above the hand) → `frame.vermillion_scene_canvas` (PaintableMesh getters → false;
+installed build checked, 72 fps headless; headset not yet). Linux apps: `desktop_icon` switch, a deleted desktop copy
+stays deleted (#212). Findings: OLAR (#201) RHIThread null deref in libUnreal (`ldr x8,[x19,#792]`, x19=0) not fixed by
+hide_space_warp / vk_hide_fdm / no Valve layers; FNAF HW (#135) "freeze" = first-start GL program-binary-cache compile
+on Zink (threads busy in zink/disk cache), not a hang; VR4 (#199) reporter's patch.203 OBB truncated. Upload benchmark
+(`scripts/upload_bench.py`, #242): home Wi-Fi caps every method at ~11 MB/s; paramiko uses ~3x OpenSSH's CPU; Windows
+OpenSSH refuses FramePort's key file (ACL "bad permissions") until its permissions are tightened.
+
+## OpenSSH uploads
+
+**OpenSSH uploads (2026-10-15, #324/#242):** sftp escapes `* ? [` inside double quotes itself (and undoes it for
+put's destination), so `native_upload.quote` escapes only `\\`/`"`; Win32 sftp turns every local backslash into `/`
+(escapes too) → local paths go as `C:/…`. Logins: `Frame.auth` = the attempt that worked (app_key / user_key = a key
+file from Settings → Installing → SSH keys, library `ssh.extra_keys`, CLI `frame ssh-keys` / agent / password).
+OpenSSH strict (FramePort + Settings keys, IdentitiesOnly) unless auth was "agent"; a refused strict login retries
+relaxed (+ private copies of ~/.ssh/id_{rsa,dsa,ecdsa,ed25519}: OpenSSH skips its defaults once any -i is given, + the
+agent); `-v` key lines go into the error. FramePort doesn't add its key to the Frame for this. Windows-tested.
+
+## Meta user id
+
+**Meta user id (GitHub #182, 2026-10-11):** OVRPort's platform loader (runtimes 3.4.3-23204ea and -aa54c3f) answers
+`ovr_GetLoggedInUserID` (and two other callers) without a Meta account with a made-up id from a helper (`stp; mov x29,
+sp; bl random; …; mov/movk x9 = 0x53444835ec580000 (6e18); add x0, x8, x9; ldp; ret`), kept only in memory → a new id
+every start; Walkabout Mini Golf files saves under `Profiles/Oculus/<id>/` and lost all progress. `frame.ovr_stable_user`
+(default_on, detect = the game has libovrplatformloader.so) rewrites the helper to `mov x0, <6e18 + 32 bits of
+sha256(package, keystore)>; ret`: stable per game and per user (keystores are personal), so online games never see two
+FramePort users as one. Found in every PATCHED build checked. Host-tested only; upstream candidate.
+
+## Vivox API 31
+
+**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.
+Photon Voice does the same (GitHub #362 Table Troopers, #325): `com.exitgames.photon.audioinaec.AudioInAEC.
+updateAudioDevice` (void; only caller of getAvailableCommunicationDevices/setCommunicationDevice, reached from the mic
+thread `AudioInAEC$1.run` via access$000; no SDK_INT check left) → sibling patch `frame.photon_voice_audio_route`
+(analysis `photon_voice_api31`, ANALYSIS_VERSION 21; shares `vivox_audio_route.patch_class`; Vivox's id, title and
+output unchanged, no revision bump). Triage: `vivox-api31` / `photon-voice-api31` now need the SDK's class in the
+stack; any other `*CommunicationDevice*` NoSuchMethodError = `audio-api31` (report). Host-tested on the real dex only.
+
+## Steam Input gamepad for 2D apps
+
+**Steam Input gamepad for 2D apps (GitHub #162, agent v72, 2026-10-10):** Lepton's Android only has the Wayland seat's `wayland_touch/keyboard/pointer`. Steam makes its virtual pad (uinput, `/devices/virtual/input`, 28de:11ff, "Microsoft X-Box 360 pad N", ACL for steamos) only while the Frame's controllers are on (controller.txt "Steam Controller reserving XInput slot 0"; gone when they sleep), also with no game running; steamos-manager's 28de:0000 keys device isn't a pad (no BTN_SOUTH). Lepton's container root (system_server too) = steamos (`keep-id:uid=0`), so a bind-mounted `/dev/input/eventN` opens. Opt-in `device.steam_gamepad` (vr_kind none; suggested for `android.hardware.gamepad`/`LEANBACK_LAUNCHER`, analysis `gamepad`, ANALYSIS_VERSION 9): deployment.json `steam_gamepad` → launcher `GAMEPAD_LINE` (after the codec line: exports FRAMEPORT_GAMEPAD + LEPTON_ENV_SDL_GAMECONTROLLER_ALLOW_STEAM_VIRTUAL_GAMEPAD, puts `agent/bin` first on PATH) → `PODMAN_WRAPPER` (written by ensure_host_fixes; non-`run` calls go straight on; `run` imports the agent's `podman_run_args`; hands on to the next Podman after its own PATH entry with itself removed from PATH, so it chains to the codec wrapper either way round) adds the pads + `Vendor_28de_Product_<pid>.kl` (Xbox 360 layout). Verified headless with a uinput stand-in pad (Stremio's container: EventHub `classes=0x80000141`, our key layout, KeyEvent BUTTON_A dispatched); with Steam's real pad and a game: not yet. Pads made after the start aren't seen until the next one.

+## Multiview programs on flat framebuffers (Doom3Quest)
+
+**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. Headset-verified by Xandrix1987 (2026-10-09: HUD/PDA shown, no fps drop) -> in the Doom3Quest catalog recipe.
+
+## BlazeRush
+
+**BlazeRush (GitHub #57, Klownicle's verified guide, 2026-10-10; FramePort's version headless-tested only):**
+`frame.blazerush` (1.0.349 only: exec-segment SHA + every word checked, offsets from PT_LOAD) NOPs the avatar-readiness
+wait (0x4b2dbc), RETs the avatar renderer (0x4b2adc), renames `cache/shader_cache` → `cache/br_shader_v1`. GL shim
+(now also exports glShaderSource/glLinkProgram/glProgramBinary/glDeleteProgram/glDraw*: pass-through unless a setting
+is on) `gl_int_attribs` (integer inputs fed via glVertexAttribPointer re-set with glVertexAttribIPointer per draw,
+reflection cached per EGL context + program, dropped on link/binary/delete) and `gl_highp_markers` (vertex shaders with
+every '|' marker: mediump→highp except on in/out/uniform lines); host test `tests/test_blazerush.py` with a stand-in
+GL. FOV: the game reads VrApi props 7/8 right after vrapi_Initialize (no session; the Frame has no
+XR_EPIC_view_configuration_fov) → the bridge saves the live FOV (also located before tracking, headless: 118.87×120.04
+on the dev Frame) in `files/framebridge-vrapi-fov.txt` and answers with it at the next start (log `FOV properties: …
+(saved by an earlier session)`). `device.config_sync` (catalog field `config_sync`, agent v78): user_config.xml
+r_3dwidth/height, r_width/height from the runtime eye size (FrameBridge logs `runtime recommended eye size`) × scale,
+written at finalize, set_settings and by launch.sh before Lepton starts (`_config_sync`). Headless runs at scale 1.7
+end in `zink: DEVICE LOST` right after the bridge's 30 s no-tracking deadline tears the session down (gpu fault at the
+teardown; not at scale 1.0): a headless-only artifact, the headset never hits that deadline. Launch tests count an exit/crash after
+such a line as a pass (triage.yaml `headless_end`, finding `headless-end`; GitHub #57 "Failed to launch" on install).
+
+## Session triage
+
+**Session triage (agent v70, 2026-10-09):** launch tests never reach FOCUSED, so real play sessions are triaged
+too. list_installed gives each game `last_play` {start, end, test} from `<anchor>/plays.log` (launch tests write a
+`test <unix>` line first → test sessions are only marked); `session_log` returns the newest session's launch.log
+(`<base>/session.log`, ≤4 MB: head + tail + FrameBridge/crash lines between) + that session's logcat-crash.log +
+`journalctl -k` GPU lines ("kernel: …"). The GUI's connection refresh (`app._check_sessions` → `pipeline.sessions_due`,
+background thread; sessions >7 days old are skipped) runs `pipeline.triage_session` = `validate/session.analyze`
+(triage.yaml signatures incl. `space-warp-used` (info, `question:`, never auto-applied), `gpu-hang` (`report: true`)
++ computed `slow-frames` (pacing windows vs the nearest refresh rate) and `focus-dips` (FrameBridge always logs
+`focus: lost` / `focus: back after N ms`, session_fixes.c)) → library `last_session` / `last_session_checked` → game
+page "Last session" callout (Try this fix / Rebuild with this fix / Yes-No question / Report / Dismiss). Suggestions may
+be values (`adapter.scale=0.85`, `triage.split_suggestion`); adapter-only fixes are pushed live (`apply_suggestions_live`
+→ agent set_settings, like the Game settings dialog). CLI `frameport session <pkg> [--apply]`. PC VR (Proton) launchers
+log no session end, so they aren't triaged yet. pac_hints stays triage-only: a survey of all 68 dump APKs found unpaired
+PAC hints in 21 libraries of 18 games (OpenSSL's 38/40 in most UE4 libUE4.so and libEOSSDK.so, UE5 libUnreal.so ~400
+vs +2-3, libass, libopencv, …), most of them games that work, so default-on would rewrite many working builds.
+
+## Install links / FrameDrop button protocol
+
+**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).
+Demo link: the homepage's example button = `deeplink.DEMO_MANIFEST` (https://frameport.app/demo/cool-game.json, published
+from site/public/demo/); every form (https button page, frameport://, framedrop://, pasted) → `InstallRequest.demo`,
+no network (fetch_manifest returns `demo_manifest()`, download refuses), `link_dialog.show_demo` (Install =
+`easter.demo_install`: Cool Game's cover out of the portal; eggs off → "Nice, it works!"), CLI just says so.
+Link updates (2026-10-17): manifest `version` (top level, or `frameport.version`, which wins; ≤64 chars) is stored in
+the entry's `link` record (+ `direct`); `pipeline.check_link_updates` (GUI start via `app._check_link_updates`, every
+6 h: setting `links.last_update_check`, off with `links.check_updates`) re-fetches web manifests that named a version
+(`deeplink.can_check_updates`: not bare file links, local manifests or the demo) and sets/clears `link_update`
+{version, checked}; versions compare with `deeplink.compare_versions` (numbers, then release > suffix). UI: Library
+`link_bar` + game page callout → `link_dialog.update_from_link` (fetch again, one confirmation, `download_and_install`
+per game; add_from_link clears the offer and keeps a name the user gave). CLI `frameport link-updates [--install]`.

+## Save backups (Quest games, agent v95, discussion #352)
+- A Lepton game's saves are two folders of `<base>/lepton-data`: `internal/<pkg>` (= `/data/data/<pkg>`:
+  `shared_prefs/`, `files/`, `databases/`; Unreal's `files/UE4Game|UnrealGame/.../Saved` often lives here) and
+  `external/Android/data/<pkg>` (= `/sdcard/Android/data/<pkg>`: Unity's `files/`, Unreal's external `Saved`). On the
+  dev Frame (2026-10-16) every file in them belongs to `steamos` (Lepton's `keep-id:uid=0`: the container's root and
+  app = steamos), mostly mode 600/660 in 700/771/775/2771 folders; Lepton's links (`Android/obb/<pkg>`, `Movies`,
+  `Download`, `Documents`) sit outside these two folders.
+- Agent `_backup_saves '<json>'` streams a tar.gz of both (members `internal/…`, `external/…`, PAX, numeric owners and
+  modes; last member `frameport-saves.json` = manifest with size + sha256 per file and what was left out) on the SSH
+  exec channel's stdout, the result JSON on stderr. Left out: folders named cache/code_cache/no_backup/il2cpp/
+  UnityShaderCache/(Vulkan)ProgramBinaryCache/GPUCache/… at any depth, Unreal `Saved/Logs|Crashes`, FrameBridge's
+  `fb_snap_*`/`framebridge*` files, `.obb/.apk/.foz/.mp4/.mkv/.webm/.mov`, symlinks and special files, and files over
+  64 MiB (big downloaded content; e.g. BattleTalent's `files/Video`). More than 4 GiB of saves is refused.
+- `_restore_saves '<json>'` reads the archive from stdin and treats it as untrusted: only regular files and folders
+  under `internal/`/`external/` (no `..`, absolute paths, links, devices, duplicates), ≤1 GiB per file / 8 GiB in all,
+  each file's sha256 must match the manifest, the manifest's package must be the game. Everything is staged in
+  `<base>/.saves-restore-*` first, a path that would pass through a link on the Frame is refused, then the current
+  saves are written to `<base>/saves-before-restore.tar.gz` (one copy; `rollback: true` restores it and keeps the
+  replaced saves as the new copy) and each file is renamed into place. Existing files keep their owner and mode, new
+  ones get their folder's owner and the backup's mode (at least u+rw); save files the backup doesn't have are removed
+  (left-out files stay). A failure while swapping puts the rollback copy back.
+- Both run their file work in `podman unshare` (the agent re-runs itself as `_saves_ns <op>` with stdio inherited) so
+  files owned by mapped ids are readable and keep their ids, take the game's launch lock (`<base>/.launch.lock`, a

+# Evaluating patch heuristics
+
+`scripts/eval_heuristics.py` compares `engine.suggest(analysis, use_catalog=False)` with the bundled
+`catalog/games/*.yaml` entries. It does not merge personal or remote catalog recipes into the benchmark.
+It supports the original dumps command, or a precomputed `scripts/heuristics_snapshot.py` snapshot:
+
+```sh
+.venv/bin/python scripts/eval_heuristics.py '<dumps folder>' --verbose
+.venv/bin/python scripts/eval_heuristics.py --snapshot analyses.json --split all --json baseline.json
+.venv/bin/python scripts/eval_heuristics.py --snapshot analyses.json --fit-report --out fit-report.md
+```
+
+Use a scratch `FRAMEPORT_HOME`, `FRAMEPORT_NO_CATALOG_UPDATE=1`, and an empty `FRAMEPORT_WINDOWS_DATA` for offline
+measurement. Snapshot mode reads no APKs or game data. Each snapshot read copies the source to a temporary file,
+then parses the copy, retrying incomplete JSON. To compare multiple splits against an actively growing snapshot,
+freeze one valid copy first and use that file for every run.
+
+The default split is `dev`. `split_packages({package: analysis_engine})` sorts packages by SHA-256 within Unity,
+Unreal, and Other strata, then holds out the nearest 20% (half rounded up). Pass only packages with both an analysis
+and a catalog entry. The same input set always yields the same split regardless of iteration order; adding packages
+can move the cutoff. Very small strata can have no holdout. Unsupported entries participate in splitting.
+
+## What is scored
+
+Ground truth contains catalog choices and patch registry defaults, with no inherited heuristic adapter settings.
+Default expectations are determined per analysis, using each default patch's own detection in the same way as the
+engine's initial heuristic pass. Thus a conditional default that is not detected (e.g. LTW on a game without LTW)
+is not expected. Explicit catalog `overport_remove` and `frame_remove` entries remove expected defaults. An absent
+expected default is represented as `remove:<patch id>`; enabled defaults do not inflate patch scores.
+
+Opt-in overport/frame/device/PC VR IDs, default removals, adapter values, device-file names, foveation parameters,
+and alternate-build patch IDs are compared. Alternate-build identities use `alt:<patch id>` so choosing one in a
+fallback is distinct from choosing it in the primary build. Device-file content is not compared. Adapter values
+must match: a wrong value contributes both an FP and an FN for `adapter.<key>`. Patch precision, recall and F1 are
+micro-averaged across games; an empty denominator is reported as zero. Exact-game accuracy also compares the
+unsupported status flag. Fields report matching games, including empty-field matches.
+
+`RUNTIME_ONLY` lists choices excluded from the headline: `use_alt`, selected runtime adapter settings, Lepton
+environment variables, and config-sync settings. They have their own exact, field and patch metrics. Catalog
+entries with status `unsupported` are excluded from both headline and runtime supported-game metrics, and have
+separate metrics and per-game diffs. Converted analyses are included and marked. JSON contains all metrics per
+engine, all game signatures, split assignments, and missing/extra decisions.
+
+## Dated score: catalog gaps vs. detection errors
+
+The strict score treats the catalog as complete, but older entries were verified before many patches existed, and
+a catalog recipe inherits every heuristic adapter setting and device patch (except `device.text_input_window`)
+without listing them (`engine.suggest`), so the verified build had those. The dated score (`headline_dated`, printed
+under "Dated") sets aside, on both sides:
+
+- patches first committed after the entry's `verified.date` (the verifier couldn't have chosen them), and
+- inherited adapter/device picks (`inherited_decisions`).
+
+What remains are real disagreements: an extra on an entry verified after the patch existed, or a catalog choice
+the heuristics don't make. Gaps are counted per patch ("Catalog gaps by patch"). The dated score needs the intro
+date cache that `--fit-report` writes; without it only inherited picks are set aside.
+
+Before tuning a rule to remove an "extra", check which kind it is: a gap on an old entry is a candidate for the
+catalog (fit report), not a detection error. Before adding a patch to a working entry, weigh its benefit (does it
+fix something the game hits?) against a rebuild prompt for everyone who installed it; adapter settings never need
+adding (inherited). Results 2026-10-15: strict 5/65 exact, F1 73.8%; dated 39/65, F1 88.6% (dev 90.5%, holdout
+79.5%). Remaining misses are one-game fixes found at runtime (e.g. Vader's gl_error_clear, BlazeRush's GL settings).
+
+An evaluation writes JSON even when its headline has differences, then exits 1 for compatibility with the original
+script. It exits 0 when exact, or after producing a fit report.
+
+## New patch fit
+
+The fit report covers all catalog entries, independently of `--split`. Candidates come from the final heuristic
+recipe, preserving platform, flat-app, dependency, and 32-bit normalization rules. A candidate must also be opt-in,
+applicable and recommended by its own `detect()`. Entries already listing or explicitly removing the patch are
+excluded; a listed adapter key is excluded regardless of its value. This report proposes additions, not value edits.
+
+Each candidate includes its reason, experimental/strict flags, first local git introduction date, catalog entry
+date (`verified.date`; `updated` only without one, since it also moves for unrelated edits), and whether the
+patch is newer. Unknown dates are marked unknown. Warnings
+come from the full catalog recipe plus that one candidate; they may include pre-existing conflicts. Missing-analysis
+entries appear as metadata-only rows. Intro dates, including unknown results, are cached in
+`patch-intro-dates.json` beside the snapshot (or dumps folder); subsequent runs only query uncached patch IDs.
+
+`tests/test_eval_heuristics.py` uses synthetic data. The opt-in real-dump test in `tests/test_games.py` ratchets the
+supported all-split exact ratio and patch F1 against measured, rounded-down baseline constants. Machine-local
+`.eval-home/` and `.eval-results/` scratch outputs are ignored by git.

+// (setting alpha_blend_emul, Vulkan sessions).
+//
+// Passthrough is emulated by compositing the game's projection layer over the Frame's cameras with its texture alpha
+// (ALPHA_BLEND environment). Unreal's mobile renderer keeps 1 - coverage in the scene alpha (0 where it drew, 1 where
+// it drew nothing), and Meta's OVRPlugin compensates with an XrCompositionLayerAlphaBlendFB on the eye layer
+// (source colour factor ONE_MINUS_SRC_ALPHA, destination SRC_ALPHA). The Frame's runtime ignores that struct, so the
+// cameras showed through the scene and the empty background stayed black (GitHub #329, Star Wars: Beyond Victory).
+// Blending src * (1 - a) + dst * a is the same as the runtime's standard blend with alpha 1 - a, so the alpha of the
+// layer's image rectangles is inverted in place, once per acquired image, by a tiny render pass (blend: one minus
+// destination alpha, zero; only alpha written) before the frame goes to the runtime. Our work is queued on the app's
+// queue ahead of the runtime's xrEndFrame submission; command buffers come from a ring and are only waited for when
+// reused, several frames later.
