Merge origin/main into site

Conflicts kept main's features with the site branch's wording: the uninstall
dialog's new delete-saves option, hardware video decoding and last-session help,
new Game settings (plain labels), agent 73 (main's 72 plus the Take screenshot
command from v66). Main's new texts follow docs/STYLE.md (for example, patch/setting
instead of fix). Pages rebuilds on docs changes and daily; the CNAME file is
gone (the domain is a Pages setting).

 **Language packs (merged from PR #20, 2026-10-04):** overport's `libovrplatformloader.so` is a dispatcher that `dlopen`s Meta's own loader (`libovrplatformloader_meta.so` / `_meta_q1.so`, also `libpxrplatformloader.so`) and keeps its own message queue; `ovr_LanguagePack_GetCurrent/SetCurrent` are 8-byte `return 0` stubs in it, `ovr_AssetFile_GetList` forwards to Meta's loader. `frame.langpacks` (opt-in, `native/langpack`) serves `<tag>.lang` files from the game's data; `elf.hide_exports` marks the loader's exports STB_LOCAL (bionic and glibc only match GLOBAL/WEAK; verified for glibc, bionic's `is_symbol_global_and_defined` is from memory). `libfp_langpack.so` is built here (`python native/build.py --only langpack`) and committed. Owner-verified 2026-10-04: Deadpool VR with only `en.lang` and the patch on plays English dialogue and runs normally (headless launch tests show 2-6 fps while it loads: not a regression sign). A dispatcher answer that arrives after we answered the timed-out GetList is dropped (one answer per request); games already in a library get `lang_packs` filled after an app update (`library._refresh_data_fields`). The library logs to logcat under the tag `fp_langpack` (dirs looked in, packs found, every language-pack call), so it shows up in the game's `launch.log`; an `ovr_AssetFile_GetList` the dispatcher leaves unanswered for 1.5 s is answered with our packs alone. Deadpool VR (Unreal) accepts a pack only when its `Metadata` equals the game's own version string (`ULanguagePacksSubsystem` compares it with `%s.%s.%s.%s.%s` built from the build info, e.g. `1.0.40.356975.Quest` = versionName; found by disassembling `libUE4.so`): the patch writes the APK's versionName into the library (`@FPMETA@` slot, `with_metadata`), `FRAMEPORT_LANGPACK_META` overrides it. Deadpool VR (2026-10-04, headset): German became selectable with that Metadata, but dialogue stayed silent (even English once reported as a pack) while the path was spelled `/sdcard/Android/obb/<pkg>/x.lang`; with the `/storage/emulated/0/Android/obb/<pkg>/x.lang` spelling (Unreal's own, now listed first in `scan_dirs`) German dialogue plays. `FRAMEPORT_LANGPACK_SKIP=<tags>` or a file `fp_langpack_skip` in the obb folder leaves packs out of the list (experiments).
 
+**Cube swapchains (GitHub #107, 2026-10-09):** the Frame's runtime refuses `faceCount=6` swapchains (-2,
+XR_ERROR_RUNTIME_FAILURE); OVRPlugin ignores that ("CreateSwapchain for eye 0: 0x0, 0 stages") and crashes in
+ovrp_EndFrame4 (memset). FrameBridge `cube_standin` (default on, `native/adapter/cube_standin.c`) serves a refused cube
+swapchain as one GL cube-map texture in the app's context (GLES only) and drops its layers. Verified headless with
+Budget Cuts Ultimate (2048² sRGB, 12 mips; runs on at ~70 fps); what the cube layer showed is simply missing.

+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

+<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

+**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).

+`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

+`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.
 **Unresolved (as of 2026-09-28):** Arcsmith (right-eye distortion) and Time Stall (both eyes) — swap, tracking, Valve
 layers, depth, pacing ruled out. Sniper Elite VR (DEVICE LOST), Espire 1 (Mesa GL upload crash), HITMAN 3 (freedreno

-Install games that target the Meta Quest, Android, or general PCVR onto your **Valve Steam Frame**. FramePort handles everything from uploading game files, setting up your Frame, injecting compatibility patches, and adding shortcuts to your Steam library. FramePort aims to be as simple as possible by taking advantage of the fact that the Steam Frame runs on Linux.
+Install Quest games, Android apps, Linux apps and PC VR games on the **Valve Steam Frame**. FramePort sets up the
+Frame, patches each game so it runs there, uploads it and adds it to your Steam library with artwork.

 ## Features
 
 ![Library](docs/images/library.png)
 
-- **Painless setup:** one short command on the Frame. No root, no `sudo`, no password.
-  [What it changes](docs/FRAME_SETUP.md).
-- **Type on Frame:** use your computer's keyboard on the Frame: in VR apps, Android apps, Steam and the desktop.
-  [More](#type-on-frame).
-- **One click per game:** convert, patch, sign, upload, add to Steam with artwork, launch test. Artwork that can't be found automatically can be picked from the stores or replaced with your own images.
-- **Per-game recipes:** a tested catalog plus detection rules; every patch explained in plain words.
-- **FrameBridge:** FramePort's OpenXR adapter emulates what the Frame natively lacks (passthrough, room, controller models,
-  curved and 360° layers); game settings as simple switches.
-- **Beyond Quest:** Android apps as windows, PC VR via Proton or Revive, Windows (non-VR) games via Proton, a Files
-  tab with drag and drop.
-- **Linux apps:** install Linux apps (AppImage, a folder, or a zip/tar archive) on the Frame with a Steam
-  shortcut; arm64 builds run natively on SteamOS, x86_64 builds through Valve's FEX translator.
-- **Install links:** "Install with FrameDrop" buttons on web pages (the one-click protocol of the FrameDrop
-  sideloader) and pasted links open in FramePort, which asks, downloads, adds and installs the build.
-- **Screenshots tab:** the screenshots you took in the headset, sorted by game (matched by play time) and day;
-  view them and download them to your computer.
-- **Live view tab:** watch what the headset shows, with sound, in a browser window on your computer.
-- **Monitor tab:** the running game's frame rate, the Frame's load, temperatures, power and battery live, and its
-  processes, which you can end. [More](#monitor).
-- **Self-updating** releases, redacted diagnostics, one-click problem reports and working-config sharing.
+- **Easy setup:** one line in the Frame's terminal. No root, no password. [What it changes](docs/FRAME_SETUP.md).
+- **One click per game:** patch, upload, add to Steam with artwork and test that it starts.
+- **Recipes:** tested patches and settings for 90+ games; other games get suggested patches, each explained in
+  plain words.
+- **Game settings:** sharpness, refresh rate, controllers, 360° video and mixed reality as simple switches.
+- **More than Quest games:** Android apps in a window, Linux apps, PC VR games and Windows programs.
+- **Install links:** "Install with FrameDrop" buttons on websites open in FramePort.
+- **Your Frame from your PC:** Type on Frame (your keyboard on the Frame), Files, Screenshots, Live view (what the
+  headset shows, in your browser) and Monitor (frame rate, temperatures, battery, processes).
+- **Updates itself**, and reports problems without personal data.
 
-## Quick start
-
-1. [Download](https://github.com/spoopyghosty0/frameport/releases/latest) and unzip the build for Windows, macOS
-   (Apple Silicon) or Linux, then start FramePort.
-2. **Connect the Frame** (once):
-   1. In FramePort click **Steam Frame → Show setup command**. Keep FramePort open; the Frame and your computer must
-      be on the same Wi-Fi.
-   2. On the Frame open the **SteamVR dashboard → Launch a program → Desktop**: the Linux desktop opens on a virtual
-      screen.
-   3. Open the app menu (bottom-left corner of that desktop) → **System → Konsole** (or search for Konsole).
-   4. Type the command FramePort shows exactly as shown (on-screen keyboard or any USB/Bluetooth keyboard) and press
-      **Enter**. This will run the following [bash setup script](bootstrap/bootstrap.sh).
-   5. After a few seconds the desktop closes by itself (Steam restarts once); that's expected. If
-      Steam asks to install **Lepton**, confirm it. FramePort shows the Frame as connected within a minute. No
-      password needed.
-3. **Add games → Scan a folder** with your game backups (APK + OBB, or PC VR game folders).
-4. Open a game → **Install on Frame**, then play it from the Frame's Steam library.
-
-Full guide, firewalls and troubleshooting: [docs/INSTALL.md](docs/INSTALL.md). Questions (e.g. how to lay out games
-with OBB files): [docs/FAQ.md](docs/FAQ.md).
-
-## Type on Frame
-
-Typing in VR is painful, so FramePort turns your computer's keyboard into a keyboard for the Frame. Open **Type on
-Frame** (its own tab in the sidebar), select a text field in the headset and type: searches, logins, chat, in any
-app, in Steam or on the desktop. Paste longer text to type it in one go. Nothing to install: FramePort adds a virtual
-keyboard on the Frame while the tab is open, without root.
-
-![Type on Frame](docs/images/type-on-frame.png)
-
-Unity apps whose text fields close the moment you select them on the Frame (no system keyboard there) get a per-game
-fix, so Steam's on-screen keyboard and Type on Frame work in them too.
-[Details](docs/INSTALL.md#typing-on-the-frame).
-
-## Screenshots
-
-Screenshots you take in the headset show up in FramePort's **Screenshots** tab, grouped by day and matched to the game
-you were playing. Open one full size, step through them, and download single shots, a selection or all of them to
-your computer.
-
-![Screenshots](docs/images/screenshots.png)
-
-![Screenshot viewer](docs/images/screenshot-viewer.png)
-
-## Live view
-
-The **Live view** tab streams what the headset shows, with its sound, to your computer: click **Start live view** and
-it opens in your default web browser (full screen with a double-click; click **Sound on** to hear it, as browsers start
-videos muted). Pick 360p to 1080p, or the headset view's full size. The picture comes from SteamVR's built-in headset
-view on the Frame and is encoded there while you watch (about one CPU core), so stop it when you're done. It's black
-while the headset sleeps.
-
-## Monitor
-
-The **Monitor** tab shows what the Frame is doing while it's open: the running game with its frame rate against the
-display's refresh rate, CPU, graphics chip, memory, the hottest temperature with the fan speed, power draw and battery
-time left, each with a 2-minute chart. **Show details** adds every CPU core, all temperature sensors, where the power
-goes and the network. Below, the game's processes (or Steam's, or all of them) with their CPU, GPU and memory use:
-right-click one to end it, or end the whole game. Programs that Steam, SteamVR or the desktop need are marked and ask
-again. The Frame sends the numbers itself (about 1 % of one CPU core) and stops when you leave the tab.
+Details for each: [Install and first steps](docs/INSTALL.md).
 
 ![Monitor](docs/images/monitor.png)
 
+![Screenshots](docs/images/screenshots.png)
+
+## Quick start
+
+1. [Download](https://github.com/spoopyghosty0/frameport/releases/latest) the build for Windows, macOS (Apple
+   Silicon) or Linux, unpack it and start FramePort.
+2. In FramePort click **Steam Frame → Start setup**. The Frame and your PC must be on the same Wi-Fi (or use a USB
+   cable).
+3. On the Frame open the **SteamVR dashboard → Launch a program → Desktop**, then the app menu → **System →
+   Konsole**, and run:
+
+   ```
+   curl -sL frameport.app/s | bash
+   ```
+
+4. Click **Allow** in FramePort when it shows the same 4-digit code as the Frame. Steam restarts once; if it asks to
+   install **Lepton** (Valve's Android runtime), confirm it.
+5. **Add games → Scan a folder…** with your games, open one and click **Install on Frame**. Play it from the Frame's
+   Steam library.

 ## Compatibility
 
-If a game has already been tested with FramePort, it will automatically use the optimal game config. Otherwise, FramePort
-will attempt to guess key patches. If you find a new config that works for an app you are testing, please consider submitting it to the community!
+Tested games use their recipe (the patches and settings that work for them) automatically; for other games FramePort
+suggests patches. See the [list of tested games](docs/GAMES.md). Got a game working? Share its recipe from the game's
+**…** menu: [how](docs/INSTALL.md#share-a-recipe-or-report-a-problem).
 
-**[List of tested games](docs/GAMES.md)**
+## Compared with other tools
 
-**Tested something? Share it.** In FramePort open the game → **…** → **Share working recipe…** (it fills in the
-recipe for you) or **Report a problem…** (attaches a diagnostics zip with personal data removed). Without the app:
-[share a working config](https://github.com/spoopyghosty0/frameport/issues/new?template=working-config.yml) · [report a problem](https://github.com/spoopyghosty0/frameport/issues/new?template=bug-report.yml). Shared configs become built-in recipes for everyone.
+FrameDrop and Valve's own tools install an app as it is. FramePort differs in four ways:
+
+- **Free and open source** (GPL-3.0). FrameDrop is free (donationware) without published source.
+- **Quest games that don't run on the Frame as they are** get converted and patched, with a tested recipe for 90+
+  games. The others install the game unchanged.
+- **Windows, macOS and Linux.** FrameDrop is for Windows.
+- **Wi-Fi or a USB cable**, and no **Pair new host** step.

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!

+status: works
+notes: 'Plays (owner''s headset test): loading card, grip/trigger, hands and the lightspeed sequence fixed. Thumbs
+  follow the touches with frame.unreal_thumb_touch (Klownicle''s engine fix).'
+details: Unreal Engine 4 (GLES). Found and verified in gameplay on a Frame by Klownicle (GitHub issue 49); FramePort
+  reimplements them as patches that match the game's code exactly and change nothing when it differs. The engine's
+  Quest checks (IsRunningOnSantaCruz) answer "not a Quest" on the Frame - the menu waited for a Quest-only shader
+  precompile that never starts (frame.unreal_quest_precompile makes the non-Quest branch report 100 %), and the
+  game's key map picked the empty Gear VR controls (frame.unreal_quest_keymap keeps the Quest set). Two lightspeed
+  shaders, as the Frame's GL driver (Zink) compiles them, read loop counters and accumulators before setting them
+  and hang the GPU; a Vulkan layer under Zink inserts the stores that zero them (frame.zink_shader_fix, zink_shader_fix;
+  the captured modules are from Lepton 2.8.14 and stop matching if a Frame update changes the driver's output -
+  the layer logs that). OVRPlugin asks for poses at its own clock (pose_time_fix). Unreal's Oculus input animates the
+  thumbs from near-touch, which the Frame never reports (frame.unreal_thumb_touch reads the touches instead; binding
+  the proximity to the touch inputs in FrameBridge didn't reach the game). The Frame's SteamVR runtime
+  leaks about 20 MB a second while the game runs (reported to Valve).

+  OVRPlugin's own clock (pose_time_fix) and thumbs from near-touch, which the Frame never reports (frame.unreal_thumb_touch).
+  Ruled out for the black picture so far (see the diagnostics in issue 61) - asset-file paks, Valve's foveation,
+  GL errors; the game's own eye image reads back black.

+The setup is the only time the Frame connects to your PC. It downloads the setup script from FramePort on TCP port
+8765 (8766 or 8767 if taken), only while the setup page is open and for at most 30 minutes. Everything else goes
+from your PC to the Frame.
 
-- **Windows:** allow FramePort (or Python, when running from source) when Windows asks. On a network Windows treats as
-  **Public** it stays blocked unless you allow public networks; set your home network to Private in Windows'
-  network settings instead.
+How the setup line finds your PC:
+
+1. FramePort announces itself on your network while the setup page is open (with your PC's name and two words, never
+   the code). If nothing answers, the setup line tries the USB cable's address and then scans the Frame's network.
+2. Both sides show the same 4 digits. Nothing happens until you click **Allow** in FramePort.
+3. FramePort then hands over the one-time code, and the Frame downloads the same setup script as the setup command.
+
+The setup line's script is [bootstrap/setup.sh](../bootstrap/setup.sh). If the setup just says "timed out", the
+setup page shows what is likely blocking it after about 45 seconds:
+
+- **Windows:** allow FramePort when Windows asks. On a network Windows treats as **Public** it stays blocked; set
+  your home network to Private in Windows' network settings.
 - **macOS:** with the firewall on (System Settings → Network → Firewall), allow incoming connections for FramePort
   when asked.
 - **Linux:** firewalld: `sudo firewall-cmd --add-port=8765/tcp` (until the next restart). ufw:
   `sudo ufw allow 8765/tcp`, afterwards `sudo ufw delete allow 8765/tcp`.
-- **WSL:** Windows' Hyper-V firewall blocks connections into WSL without asking. FramePort adds a temporary rule for
-  the setup ports (one admin prompt) and removes it again when setup is done or after 35 minutes. WSL must use
-  mirrored networking: `networkingMode=mirrored` under `[wsl2]` in `%UserProfile%\.wslconfig`, then `wsl --shutdown`.
-- Or skip the setup command and use the devkit pairing (see [INSTALL.md](INSTALL.md#connecting-the-steam-frame)): it needs no connection into your computer.

-- **Windows:** "Windows protected your PC" → **More info** → **Run anyway**. Optional: import
-  `FramePort-selfsigned.cer` (attached to each release) into *Trusted Root Certification Authorities* (Current User) to
-  show FramePort as the publisher; the certificate can only sign code. Remove it with `certmgr.msc`.

 ## Connecting the Steam Frame
 
-The Frame and the computer must be on the same network.
+The Frame and your PC must be on the same network (or connected with a [USB cable](#with-a-usb-cable)).
 
-1. In FramePort open **Steam Frame** and click **Show setup command**.
-2. First time only, on the Frame:
-   1. Open the **SteamVR dashboard → Launch a program → Desktop**: the Linux desktop opens on a virtual screen.
-   2. Open the app menu (bottom-left corner of that desktop) → **System → Konsole** (or search for Konsole).
-   3. Type the command FramePort shows exactly as shown (on-screen keyboard or any USB/Bluetooth keyboard) and press
-      **Enter**. It looks like `curl -fsS 192.168.1.20:8765/1a2b3c4d | bash`: your computer's address, then a
-      one-time code.
-   4. After a few seconds the desktop closes by itself (Steam restarts once); that's expected. If
-      Steam asks to install **Lepton** (Valve's Android runtime), confirm it.
+1. In FramePort open **Steam Frame** and click **Start setup**. Keep that page open.
+2. On the Frame, first time only:
+   1. Open the **SteamVR dashboard → Launch a program → Desktop**. The Frame's desktop opens.
+   2. Open the app menu (bottom left) → **System → Konsole**, the Frame's terminal.
+   3. Type this setup line and press **Enter** (on-screen keyboard or any USB or Bluetooth keyboard):
 
-   FramePort connects by itself within a minute. No password is needed. The command lets FramePort in and turns on
-   **Developer Mode** (which includes SSH); everything it changes is listed in [FRAME_SETUP.md](FRAME_SETUP.md).
-3. Later starts: a Frame in Developer Mode appears in the list and FramePort connects to it automatically. (If you
-   turn Developer Mode off in Settings → System → Developer, turn it on again there.)
+      ```
+      curl -sL frameport.app/s | bash
+      ```
 
-**Without Konsole:** turn on Developer Mode yourself (Settings → System → Developer). The Frame then appears under
-**On your network**. On the Frame open Settings → Developer → **Pair new host**, then click **Connect** in FramePort
-and approve it on the Frame (Valve's own devkit pairing; it only sends this computer's key to the Frame). Install
-Lepton from the Steam Frame page afterwards if it's missing.
+      No keyboard? Open [the setup page](https://frameport.app/setup/) in Chromium on the Frame,
+      tap **Copy** and paste it into Konsole.
+   4. Konsole shows a 4-digit code. When FramePort shows the same code, click **Allow**. Nothing changes on the Frame
+      before that.
+   5. Steam restarts once and the desktop closes. If Steam asks to install **Lepton** (Valve's Android runtime),
+      confirm it.
+
+FramePort connects within a minute. No password is needed. The setup turns on **Developer Mode**;
+[What the setup changes](FRAME_SETUP.md) lists everything.
+
+Later, FramePort connects to the Frame by itself. If you turn Developer Mode off (Settings → System → **Enable
+Developer Mode**), turn it on again there.
+
+**Setup command:** if your network blocks FramePort's search, click **Use the setup command**. It shows a line with
+your PC's address and a one-time code, for example `curl -fsS 192.168.1.20:8765/1a2b3c4d | bash`. Run it in Konsole instead.
+
+**Without Konsole:** turn on Developer Mode yourself (Settings → System → **Enable Developer Mode**), then open
+Settings → Developer → **Pair new host** on the Frame. FramePort finds the Frame and asks to connect; approve it in the
+headset. Install Lepton from FramePort's Steam Frame page afterwards if it's missing.
 
 ### With a USB cable
 
-For networks that block the setup (guest Wi-Fi, firewalls, discovery not working), and for faster uploads:
+A cable works on networks that block the setup, and uploads are faster (about 37 MB/s, three times typical Wi-Fi).
 
-1. On the Frame, turn on **Developer Mode** (Settings → System → Developer Mode). The Frame's USB network only exists
-   in Developer Mode.
-2. Connect the Frame's USB-C port to the computer.
-3. In FramePort: **Steam Frame → Set up with a USB cable**. FramePort detects the cable and shows the setup command,
-   which reaches the computer over the cable. Already set up? It connects over the cable right away.
+1. On the Frame, turn on Developer Mode (Settings → System → **Enable Developer Mode**). The cable only works in
+   Developer Mode.
+2. Connect the Frame's USB-C port to your PC. No driver is needed.
+3. In FramePort click **Steam Frame → Set up with a USB cable** and follow the steps.
 
-The cable needs no driver on Windows 10/11, macOS or Linux, and the computer gets an address from the Frame
-automatically. Uploads use the cable whenever it's plugged in (about 37 MB/s, ~3× typical Wi-Fi), even when FramePort
-connected over Wi-Fi. Unplug it any time: FramePort finds the Frame on Wi-Fi again by itself.
+Uploads use the cable whenever it's plugged in. Unplug it any time: FramePort finds the Frame on Wi-Fi again.
 
 ### Firewalls
 
-If the setup command only says "timed out", a firewall on your computer blocks the Frame; the setup page
-says which after about 45 seconds. Details per system: [FRAME_SETUP.md](FRAME_SETUP.md#network-and-firewalls).

 ## Running FramePort on the Frame (experimental)
 
-FramePort can run on the Steam Frame itself, without a PC: in **Desktop Mode**, download
-`FramePort-linux-arm64.tar.gz`, unpack it (`tar xzf FramePort-linux-arm64.tar.gz`) and start `FramePort/FramePort`.
-Turn on **Developer Mode** first (Steam → Settings → System); FramePort then manages "This Frame" directly, with
-no pairing. Games are added to the Steam library when you go back to **Gaming Mode** (Steam has to restart for it,
-which would end Desktop Mode). This is new: please report anything odd with **Report a problem**.

 ## Installing games
 
-- **Install on Frame** on a game's page (or select several in the Library and install them together). Installs run
-  one after another in the background; **Activity** shows the current one at the top.
-- **Update all** reinstalls every game whose build changed (e.g. after a FramePort update). Questions that need an
-  answer (e.g. Oculus games that can't run on the Frame) are asked once, for all games.
-- If the Frame goes to sleep, turns off or leaves the Wi-Fi, the queue **waits** and continues once it's back; uploads
-  pick up where they stopped. While installs run, FramePort keeps the Frame from going to sleep. Before a large batch
-  it checks the Frame has enough free space.
-- **microSD card / other drives:** the **Steam Frame** page's **Storage** section lists the Frame's drives and sets
-  where new games go (**Install new games to**). Games go into a `FramePort` folder on the card. To move a game that's
-  installed already, right-click it → **Move to…** (the game must be closed; saves, settings and the Steam entry stay).
-  A game on the card only starts while the card is inserted (FramePort then says "SD Card not inserted"). Cards
-  formatted as FAT, exFAT or NTFS can't hold games: format the card in SteamOS first.
-- Your own game files are never changed. The converted copy is temporary: it's removed once the game is on the Frame
-  (Settings → Installing: keep them, or remove all now).
-- **Game settings…** (game menu or the Steam Frame page): sharpness, refresh rate, controllers, menus, 360° video and
-  mixed-reality options in plain words, only those that matter for the game. Changes are kept with the game and,
-  when it's installed, used the next time it starts.
-- Ordinary Android apps (no VR) are installed unchanged and shown as a flat window in the headset. Android's
-  back/home/recents buttons are hidden by default (patch **Hide Android's navigation bar**). If FramePort guesses
-  wrong (a phone app shows nothing in the headset, or a VR app opens as a flat window), choose **VR** or **Flat
-  window** under **Show as VR or as a flat window** in the game's **Customize** section, then **Update on Frame**.
-- **Add games → Add a Windows program…** adds a single Windows program; the Frame runs it through Proton (as a
-  window unless it is a VR game). A program sitting in Downloads, the home folder or a drive root is copied on its
-  own first, so the install doesn't upload everything next to it.
-- In the packaged app you can also **drag files onto the Library**: APKs, Linux apps (AppImage, `.zip`/`.tar.gz`),
-  Windows programs (`.exe`), folders, or a FrameDrop manifest (`.json`).
-
-### Install links ("Install with FrameDrop" buttons)
-
-Some developers put an **Install with FrameDrop** button on their site (the one-click protocol of the FrameDrop
-sideloader, documented at framedropvr.com/docs). FramePort understands the same links:
-
-- **Clicking a button** opens FramePort (or the window that's already open) on Windows and Linux. FramePort shows
-  the title, the files, their size and whether a checksum is given, and asks before it downloads anything. Then it
-  downloads the build, adds it to your library and starts the usual install on the Frame. If no Frame is connected,
-  the game is added now and installs once the Frame is back.
-- **Add games → Add from a link…** takes the button's address (right-click → Copy link), a `framedrop://` or
-  `frameport://` link, a manifest (`.json`) or a direct link to an APK, a Linux build or a Windows program. Use it on
-  macOS, where web pages can't hand links to FramePort yet.
-- **Settings → Install links** has one switch for `framedrop://` links (the buttons) and one for FramePort's own
-  `frameport://` links. Both are on by default. If FrameDrop is installed too and already opens `framedrop://`
-  links, FramePort leaves them to it; **Use FramePort for these links** takes them over (turn the switch off to give
-  them back).
-- **For developers:** a FrameDrop manifest works as it is
-  (`{"schema": "framedrop.install/v1", "name": "…", "files": [{"url": "https://…", "sha256": "…"}]}`). FramePort
-  also reads an optional `"frameport": {"description": "…", "icon": "https://….png"}` object (FrameDrop ignores
-  it): the install question then shows the icon and description, and they become the game's icon and "About this
-  game" text when no store has them. For your page there's an "Install with FramePort" button:
-  [INSTALL_BUTTON.md](INSTALL_BUTTON.md). Without a manifest (a bare file link) FramePort guesses the title from the
-  file name and replaces it with the app's own name once it's downloaded.
-- Only `https://` links to public servers are used (plain `http://` only on this PC, for testing); links with a
-  user name or password, or pointing into your local network, are refused. Only install from sites you trust.

 ## Typing on the Frame
 
-- **Type on Frame** (its own tab in the sidebar; also on the Steam Frame page): while the tab is
-  open, this computer's keyboard works as a keyboard plugged into the Frame. Select a text field in the headset (in
-  an app, Steam or the desktop) and type; Esc and shortcuts go to the Frame too. Paste longer text into the box to
-  type it in one go (US keyboard layout). Opening another tab disconnects the keyboard.
-- **Steam's on-screen keyboard** opens for text fields of apps shown as a window (2D apps, and VR apps with
-  **Show the app's Android window**). Steam lists that window as **Gamescope** (the Frame's display compositor);
-  leave it open: it's what receives the typing, the VR view isn't affected.
-- **Unity apps whose text fields close at once** (a caret flashes, nothing can be typed): FramePort suggests
-  **Make Unity text fields work** for them. The first time, it downloads Cpp2IL (a tool that finds the right spot in the
-  game's code, ~17 MB). Games added before this version: open the game's menu → **Analyze again**, then reinstall.

-## Watching the Frame (Monitor)
+![Type on Frame](images/type-on-frame.png)
 
-- **Monitor** (its own tab in the sidebar) shows live what the Frame is doing while the tab is open: the running game
-  with its frame rate (Quest games), CPU, graphics chip, memory, the hottest temperature with the fan speed, power
-  draw and battery time left, each with a 2-minute chart. **Show details** adds every CPU core, all temperature
-  sensors, where the power goes and the network.
-- **Processes**: **Game** (default) lists the running game's processes, **Steam & SteamVR** and **All** show more.
-  Right-click a process (or use **⋯**) to end it, force-kill it or end its whole game; **End game** on the game card
-  closes the game the way Steam's Exit game does. A lock marks programs whose end would close Steam, SteamVR or the
-  desktop: FramePort asks again before ending those.
-- The numbers come every second (or every 2/5 s) and cost the Frame about 1 % of one CPU core; nothing keeps
-  running on the Frame after you leave the tab.

+  battery, each with a 2-minute chart. **Show details** shows more.
+- Under **Processes**, right-click a process to end it. **End game** closes the game like Steam's Exit game. A lock
+  marks programs Steam or the desktop needs; FramePort asks again before ending those.
+- **Live view** streams what the headset shows, with sound, to your browser. It uses about one CPU core of the Frame,
+  so stop it when you're done.
+- **Screenshots** shows the screenshots you took in the headset, sorted by game and day, to view or download.
 
 ## Updating
 
-**Game configs** (the tested recipes in the catalog) update by themselves: FramePort checks GitHub every 6 hours for
-newly confirmed or fixed configs and uses them without a FramePort update; a game whose recipe changed then shows
-**Update on Frame**. Configs that need a newer FramePort are skipped until you update. Settings → Data shows the last
-check (**Check now**) and turns this off.
+FramePort checks for a new version at start and every 6 hours. When there is one, the Library shows **Update now**:
+FramePort downloads it, checks it, restarts and keeps your games and settings. **Later** skips that version.
 
-
-FramePort checks for a new release at start and every 6 hours (it only downloads the release information). When one
-exists, the Library shows **Update now**: FramePort downloads the new version, verifies it against the release's
-`SHA256SUMS.txt` (on Windows also the signature), restarts and opens as the new version. Games, settings, signing keys
-and the Frame connection are kept. Running installs finish first. **Later** skips that version.
-
-Settings → **Updates**: turn the check off, or turn on **Install updates automatically** (downloads in the background,
-installs at the next start). If FramePort's folder isn't writable, **Update now** opens the release page instead. The
-update log is `logs/update.log` in the data folder.
-
-**Dev builds:** when you're asked to test a fix before it's released, use Settings → Updates → **Install the latest
-dev build…**. It shows what to test, then installs like an update (same checks). Dev builds are less tested; the next
-release is offered to you as a normal update.
-
-Command line: `frameport update` (`--check` only checks, exit code 10 = update available; `--yes` doesn't ask).
-`FRAMEPORT_NO_UPDATE_CHECK=1` turns all checks off.
+- Settings → **Updates** turns the check off or turns on **Install updates automatically**.
+- **Recipes** (the tested patches and settings for each game) update by themselves. A game whose recipe changed shows
+  **Update on Frame**.
+- **Dev builds:** if you're asked to test a change before its release, use Settings → Updates → **Install the latest
+  dev build…**. The next release then arrives as a normal update.
 
 ## PC VR games
 
-PC VR games are Windows VR games (OpenXR, SteamVR or Oculus). Scan a folder of them (one folder per game) or use
-**Add games → Add a PC game folder…**. FramePort finds the game's program and asks when there is more than one
-candidate. **Already patched** on a game page installs a copy unchanged. Oculus-only games need Revive: FramePort uses
-an installed Revive, or downloads a portable copy.
+PC VR games are Windows VR games. Scan a folder of them (one folder per game) or use **Add games → Add a PC game
+folder…**. FramePort asks which program starts the game if it finds more than one.
 
-- **Play from this PC:** Windows with Steam and SteamVR. **Install on this PC** adds the game to Steam; stream it to the
-  Frame with Steam Link. If a game can't keep up with the refresh rate, FramePort lowers the rate and enables motion
-  smoothing in SteamVR's per-game settings the next time you press Play.
-- **Play on the Frame (experimental):** Steam Frame → *PC VR games (Proton)* → **Install**, then **Install on Frame**
-  on the game page.
-- Games that use the Oculus Platform SDK check the licence through the Oculus app, so they run on the PC only.
+- **Play from this PC** (Windows with Steam and SteamVR): **Install on this PC** adds the game to Steam. Stream it to
+  the Frame with Steam Link.
+- **Play on the Frame (experimental):** on the Steam Frame page, install *PC VR games (Proton)*, then click **Install
+  on Frame** on the game's page.
+- **Oculus games** (made for Meta's Rift headset) need Revive, which FramePort downloads. Games that check their
+  license through the Oculus app only run on your PC.
 
-**Windows games without VR:** **Add games → Add a PC game folder…** with the game's folder (pick the program that
-starts it if asked). FramePort installs it on the Frame and Proton runs it as a window, like Steam's own Windows games;
-it shows up in the Frame's Steam library tagged "Windows game on Frame". Whether a game runs depends on Proton on ARM
-(x86 games run through emulation).
+**Windows games without VR:** use **Add games → Add a PC game folder…** too. The Frame runs them as a window through
+Proton, like Steam's own Windows games. Whether a game runs depends on Proton.
 
 ## Linux apps
 
-The Frame runs SteamOS on an arm64 CPU, so native Linux apps built for **aarch64/arm64** run on it directly (no
-Android container, no Proton). **Add games → Add a Linux app…** takes an AppImage or a `.zip`/`.tar.gz`/
-`.tar.xz` archive; **Add a Linux app folder…** takes an unpacked app. FramePort finds the program that starts it (the
-game page's **Change…** picks another one) and whether it's a VR (OpenXR) app. **Install on Frame** uploads it
-unchanged and adds it to the Frame's Steam library, tagged "Linux app on Frame"; Play, launch tests and Uninstall
-work like for other games.
+**Add games → Add a Linux app…** takes an AppImage (a single-file Linux app) or a `.zip`/`.tar.gz`/`.tar.xz`
+archive; **Add a Linux app folder…** takes an unpacked app. **Install on Frame** uploads it unchanged and adds it to
+the Steam library.
 
-- **x86_64 builds** run through **FEX**, Valve's x86 translator, with the x86 system libraries SteamOS ships for it
-  (the way Steam on the Frame runs x86 Linux games). The first install of one installs FEX on the Frame (Steam
-  restarts once and downloads it, a few MB). They run slower than arm64 builds: when an app offers both, FramePort picks the arm64 one. The game
-  page shows which CPU a build is for.
-- The app must bring the libraries SteamOS doesn't have (checked for arm64 builds; x86_64 builds use FEX's x86
-  system, which has glibc and Mesa, and aren't checked ahead). If some are missing, the install reports them and the game
-  page lists them: look for a build that includes them.
-- **Desktop Mode:** Linux apps also appear in Desktop Mode's application menu and as an icon on its desktop. Some
-  apps work better there, with a mouse and keyboard, than in Gaming Mode (where Steam Input turns the controllers into
-  a gamepad). Switch it off per app on the game page (**Desktop Mode**).
-- From the command line: `frameport add-linux <AppImage, folder or archive> [--exe <program>]`.
+- Apps built for **arm64** (the Frame's processor) run directly. Apps built for **x86_64** (most PCs) run through FEX,
+  a translator Steam installs on the Frame the first time; they run slower. The game page shows which kind you have.
+- If the app needs libraries the Frame doesn't have, the game page lists them: look for a build that includes them.
+- Linux apps also appear in **Desktop Mode**'s app menu. Turn this off on the game
+  page (**Desktop Mode**).
 
-## Files on the Frame (videos, documents, mods, saves)
+## Files on the Frame
 
-The **Files** tab manages files on the Frame over the same connection as installs; no other transfer app is needed.
-Pick a location, browse folders, and use **Upload files** / **Upload folder**, **New folder**, or the download, rename
-and delete buttons on each entry. Right-click an entry (or the empty space) for the same actions in a menu. Tick
-several entries (or the box above the list for all), or click and drag across them, to download or delete them
-together; a right-click on one of them then acts on all. The **Screenshots** tab and the **Library** work the same
-way: right-click for a menu, drag across cards to select several. In the downloaded app you can also drag files and folders from Explorer / Finder / your file manager onto
-the list to upload them into the open folder. Uploads and downloads run in the Activity panel, resume after an interruption and
-skip files that are already there.
+The **Files** tab copies files between your PC and the Frame: videos, documents, mods and saves.
 
-- **Videos**, **Downloads** and **Documents** appear inside every Quest game as `/sdcard/Movies`, `/sdcard/Download`
-  and `/sdcard/Documents`. Apps find files by browsing folders; Android's media index doesn't work on the Frame.
-- Under **Game storage**, each installed game has its own `/sdcard` (mods, saves). A game's menu → **Add videos and
-  files…** opens it. Video players that list only their own folder (e.g. 4XVR's "Internal Storage" = `4XPlayer`) find
-  videos uploaded into that folder.
-- **Home folder** shows everything in the Frame's home folder (hidden files with **Show hidden files**).
+![Files](images/files.png)
 
-Command line: `frameport frame send <files> --dest videos` (`frameport frame storage` lists the destinations).
+- Use **Upload files**, **Upload folder** and **New folder**; right-click an entry to download, rename or delete
+  it. Drag across entries to select several.
+- In the downloaded app you can drag files from your PC onto the list.
+- **Videos**, **Downloads** and **Documents** are shared by every Quest game (inside the game: `/sdcard/Movies`,
+  `/sdcard/Download`, `/sdcard/Documents`).
+- **Game storage** holds each game's own files. A game's menu → **Add videos and files…** opens it.
 
-## Sharing a working game, reporting a problem
+## Share a recipe or report a problem

-and `frameport <command> --help` describe every option. The main ones:
-
-| Command | What it does |
-|---|---|
-| `scan <folder>` / `list` / `show <game>` | add games, list the library, show a game's analysis and patches |
-| `add-linux <path>` | add a Linux app, arm64 or x86_64 (AppImage, folder or archive) |
-| `recipe <game> --enable/--disable <patch>` | change a game's patches (`patches` lists them all) |
-| `build <game>` / `install <game>` / `test <game>` | build, install on the Frame (`--to pc` for PC VR on this PC), launch test |
-| `frame discover` / `frame connect` / `frame info` | find, pair with and describe the Frame |
-| `frame send` / `frame storage` / `frame cleanup` | copy files to the Frame, show where they go, free space |
-| `frame drives` / `frame move <game> --to <drive>` / `install --dest <drive>` | the Frame's drives (microSD), move a game, install to a drive |
-| `tools status` / `tools install` | the tools FramePort downloads |
-| `open-link "<link>"` | install from an "Install with FrameDrop" button's address or a manifest/APK/zip link (`--yes`, `--no-install`) |

 ## Uninstalling
 
-Settings → **Uninstall FramePort…** (or `frameport uninstall-app`) removes its data folder, the Steam shortcuts it
-added on this computer and, optionally, its games on the Frame (saves can be kept). It first saves your signing keys
-to Documents: game updates must be signed with the same key. Then delete the program folder.

 ## Verify a download
 
-Each archive has a GitHub build attestation:
-`gh attestation verify FramePort-windows-x64.zip -R spoopyghosty0/frameport`. `SHA256SUMS.txt` lists the checksums
-(`sha256sum -c SHA256SUMS.txt`). Windows certificate SHA-256 fingerprint:
+`SHA256SUMS.txt` in each release lists the files' checksums: `sha256sum -c SHA256SUMS.txt`. Each file also has a
+GitHub build attestation (proof that GitHub built it from this repository):
+`gh attestation verify FramePort-windows-x64.zip -R spoopyghosty0/frameport`.
+
+Windows: to show FramePort as the publisher, import `FramePort-selfsigned.cer` (attached to each release) into
+*Trusted Root Certification Authorities* (Current User). The certificate can only sign code; remove it with
+`certmgr.msc`. Its SHA-256 fingerprint:

-| Black flat window, then a GPU hang: kernel `hangcheck detected gpu lockup` (offending task the game), `zink: DEVICE LOST`, Unity render-thread crash; `outside of frame bounds` thousands of times a second (e.g. BattleSisters, Unity 2019.4) | Unity 2019 on its built-in VR (no `libOculusXRPlugin.so`) uses the same legacy frame loop as Unity 2017: no `xrWaitFrame`, the render thread floods the GPU | `frame.unity_oculus_check` adds the ovrpshim frame wait for these too (revision 2) |
-| Unity built-in VR game (with `frame.unity_oculus_check`) freezes at a scene switch: the log stops after `Boot: Activating Scene: …`, the process stays alive, every thread sleeps (e.g. Sniper Elite VR, Unity 2019.4) | The shim's `xrWaitFrame` blocks until the previously waited frame is begun; Unity skipped beginning it at the scene switch and its render thread then waited for the main thread (gdb: UnityMain in vrclient `CSxrSession::StartNextFrame` ← `ovrp_WaitToBeginFrame` ← `fpov_Update2`). OVRPlugin also only begins the frame index it waited for | `frame.unity_oculus_check` revision 5: libunity.so's `ovrp_BeginFrame`/`ovrp_EndFrame` go through the shim, which waits ≤ 50 ms for the last waited frame to begin, else skips the wait (log `the last waited frame wasn't begun`), and gives a begin/end of another index the waited one |
-| Unity built-in VR game: the hands/weapons trail the controllers by centimetres when moving (headset fine, 72 fps), e.g. Sniper Elite VR | Unity's physics-step `ovrp_Update2` (prediction 0) makes OVRPlugin locate the nodes at the monotonic clock's "now", the XrTime base on a Quest but 0.05–0.9 s behind the Frame's XrTime; the runtime extrapolates backwards and the render-step reads after it get those poses too. A larger prediction is capped by OVRPlugin (~0.07 s) | `frame.unity_oculus_check` revision 5 holds the physics-step update back: both steps read the render update's display-time poses |
-| Unreal game stuck on a loading image after the intro, frames keep coming (72 fps), no crash (e.g. Vader Immortal) | suspect: a Meta Platform SDK request no message ever answers | diagnostics: `frame.ovr_trace` (opt-in) logs every `ovr_*` call, the answers `ovr_PopMessage` returns and every 10 s the unanswered requests (`fp_ovrtrace` in launch.log). Never fake an entitlement answer |
-| Own-engine game crashes in `libVkLayer_fossilize.so` (Fossilize's recording thread, e.g. Roblox) | same as Deadpool VR: uninitialised pointers in what Fossilize records | `frame.vk_sanitize` now also covers own-engine libraries that load `libvulkan.so` by name |
-| Crash right after the game gets focus, in `vrclient.so … UpdateActionStateInternal` / `sxr_xrSyncActions` (e.g. Myst) | a race in the Frame runtime's input code on the first sync after focus (not every launch) | adapter `sync_guard` (input syncs one at a time with event polling, paused 250 ms after FOCUSED) |
-| View jumps sideways / game pauses or freezes for a moment every few seconds (e.g. Blade & Sorcery, BattleGlide) | the Frame drops focus for ~0.5 s (FOCUSED→VISIBLE→SYNCHRONIZED); games pause or re-align the player (`OnVRPresence … Teleport`) | adapter `focus_hold` |
-| SDL / LÖVE app crashes at start: `NullPointerException … ClipboardManager.addPrimaryClipChangedListener` in `SDLClipboardHandler.<init>` (e.g. Dramatic Shape) | Lepton's Android has no clipboard service (`service check clipboard`: not found) | `frame.sdl_clipboard` (that call → nops in classes.dex, in place, `apk/dex.py`); reproduced and verified with LÖVE for Android 11.5 |
-| Controllers do nothing (e.g. stuck on a setup screen); log: `xrSuggestInteractionProfileBindings … XR_ERROR_PATH_UNSUPPORTED` | the game only suggests bindings for Meta's newer profiles (Touch Plus / Touch Pro); the Frame's Android runtime knows `oculus/touch_controller`, not those | adapter `profile_remap` (default on): the bindings are suggested again for Touch (log: `controller profile … -> oculus/touch_controller`) |
-| Some buttons do nothing or the wrong thing (e.g. a Quest game's X/Y on the Frame's left controller) | the game binds only Quest Touch and SteamVR maps Touch onto the Frame controllers with its own remap (Touch left X/Y land on the d-pad, right X and Y repeat B), or the runtime rejected a profile or an input call | turn on adapter `input_diag` (diagnostics, off by default; `frameport settings <pkg> input_diag=1`) and look for `input_diag:` lines: `bindings: <profile> accepted` or `unsupported: interaction profile <profile> -> <result>` with the rejected paths, `bindings: /user/hand/<hand> uses <profile>`, `unsupported: function <name>`, `unsupported: xrCreateAction -> <result> (<action>)` |
-| Unity game hangs or the whole Frame restarts (e.g. in a menu); log: `The current MSAA level is 0, but the recommended MSAA level is 4. Switching to the recommended level.` (e.g. Lucky's Tale) | Meta's OVRManager (`useRecommendedMSAALevel`) turns 4x MSAA on at runtime, past QualitySettings; multisampled render-to-texture on GLES/Zink hangs the GPU | `frame.unity_runtime_msaa_off` (Cpp2IL: `OVRDisplay.get_recommendedMSAALevel` → 0) |
-| Unity game: one eye shows only effects or grey, the other is fine (e.g. I Am Cat, Oculus XR Plugin on GLES) | the game's single-pass multiview rendering goes wrong for array slice 1 (the adapter submits both slices correctly) | `frame.unity_multipass` (Cpp2IL: `OculusSettings.GetStereoRenderingMode` → MultiPass); `swap_eyes=1` tells whether the game or the adapter is at fault |
+| Crash with `SIGILL (ILL_ILLOPN)` and `*pc=0xd50323bf` (autiasp), for example on Unreal's HttpManager thread (GitHub #83 Star Wars Pinball VR, triage `pac-unpaired`) | The engine's OpenSSL ARMv8 assembly has autiasp without a matching paciasp (libUE4.so: 38 paciasp, 40 autiasp; Poly1305 NEON). Quest CPUs treat PAC hints as NOPs, the Frame's CPU checks them | `frame.pac_hints`: in a library with unpaired counts every paciasp/autiasp becomes a NOP (in place) |
+| launch.log ends with `logcat: Unexpected EOF!` right after `Waiting for app …`; the game runs, but Steam's "Resume game" menu isn't closed and the launch test shows nothing (Vader Immortal on Lepton 3.0.5, Under Cover on 2.8.14; about 1 launch in 50) | Lepton's logcat mirror died | Agent v67 `_logcat_keeper` (started by launch.sh, added to older launchers by `upgrade_launchers`) reads the container's logcat itself (`podman exec lepton-steamlaunch-<appid> logcat -v threadtime -T 2000`) and appends it to launch.log; log `<base>/logcat-keeper.log` |
+| A game no longer starts after a reinstall that was launch-tested right away: logcat `Zip: EOCD not found, …/base.apk is not zip` / `Failed to parse …base.apk`, no `Start proc` for the game (VR HOT, 2026-10-09) | The launch test's 45 s ran from the launcher, but the first start after an APK change spends ~1–2 min booting Lepton and installing the app: stopping the container mid-install left a broken installed copy | Agent v68: the test window counts from Lepton's `Waiting for app` (at most 240 s extra for boot + install). Repair a broken one: `touch <base>/lepton-app/game.apk` (Lepton re-installs it on the next start) |
+| Unreal game (OVRPlugin) never starts VR: launch.log has `OVRPlugin: JNI_OnLoad` but never `CompositorOpenXR::PreInitialize`, no OpenXR session, then a crash a few seconds in (for example Star Wars Pinball VR, UE 4.25: null pointer in `FSceneRenderer::GetMultiViewSceneColor`, GitHub #83) | Unreal's Oculus module looks up every `ovrp_*` function of the OVRPlugin it was built against (`InitializeOculusPluginWrapper`, all ANDed); OVRPort's OpenXR OVRPlugin lacks a few old ones (UE 4.25 / OVRPlugin 1.44: `ovrp_GetPTWNear`), so the wrapper fails and OculusHMD is never pre-initialized | `frame.unreal_ovrp_entrypoints` (suggested when analysis `unreal_ovrp_lookups` name functions the shipped OVRPlugin lacks): generated `libfp_ovrpstubs.so` (DT_NEEDED of libOVRPlugin.so; dlsym on the plugin's handle searches its dependencies) with a stand-in per missing name returning ovrpFailure (-1000); build note lists the names |
+| Only the Android home screen shows; the log has Unity's VR device as `None` (for example Accounting+, Unity 2017) | Unity 2017–2018 built-in Oculus support starts VR only when `com.oculus.systemactivities` is installed; Lepton has no Meta system apps, so Unity falls back to non-VR | `frame.unity_oculus_check`: that package name in libunity.so → `android`, plus `native/ovrpshim` (libfp_ovrp.so): Unity 2017's legacy frame loop (`ovrp_Update2`/`ovrp_BeginFrame`) never calls `ovrp_WaitToBeginFrame`, so without the shim no `xrWaitFrame` happens, `CompositorOpenXR::Update … outside of frame bounds` floods the log and the dashboard freezes. With it: log `ovrp frame loop shim: waited for frame N`, ~71 fps. Accounting+ then stops at "press any button" although its OVRInput gets clean input (`INPUT_PROBE` in the patch logs connected controllers/buttons/input focus per call) — unresolved |
+| Stuck on the loading screen or quits at start; `Unable to open archive file`, `is corrupted! Remove it and launch unity again` or `Failed to read data for the AssetBundle` in launch.log (for example Batman, GitHub #155) | The game's data folder (OBB) is incomplete or from another version than the APK | Copy the whole data folder again from the same install as the APK, add the game again, reinstall (triage `unity-data-missing`) |
+| Black flat window, then a GPU hang: kernel `hangcheck detected gpu lockup` (offending task the game), `zink: DEVICE LOST`, Unity render-thread crash; `outside of frame bounds` thousands of times a second (for example BattleSisters, Unity 2019.4) | Unity 2019 on its built-in VR (no `libOculusXRPlugin.so`) uses the same legacy frame loop as Unity 2017: no `xrWaitFrame`, the render thread floods the GPU | `frame.unity_oculus_check` adds the ovrpshim frame wait for these too (revision 2) |

+| Unity built-in VR game: the hands/weapons trail the controllers by centimetres when moving (headset fine, 72 fps), for example Sniper Elite VR | Unity's physics-step `ovrp_Update2` (prediction 0) makes OVRPlugin locate the nodes at the monotonic clock's "now", the XrTime base on a Quest but 0.05–0.9 s behind the Frame's XrTime; the runtime extrapolates backwards and the render-step reads after it get those poses too. A larger prediction is capped by OVRPlugin (~0.07 s) | `frame.unity_oculus_check` revision 5 holds the physics-step update back: both steps read the render update's display-time poses |
+| OVRPlugin game: the hands lag behind the controllers (also with `ovrp_hold_physics` on or off; rendering fine), for example BattleSisters | OVRPlugin passes its monotonic-clock "now" on as the OpenXR time (OVRPort's dispatcher converts XR_KHR_convert_timespec_time 1:1: the Frame's runtime lacks it, and FrameBridge's emulation is never asked), but the Frame's XrTime runs ahead of CLOCK_MONOTONIC (2.56 s on SteamOS 0.4.5): with `pose_debug=1` the hand spaces show `time - predicted display time -2564 ms`; BattleSisters also asks for its head at XrTime 0.1 s every frame | `adapter.pose_time_fix` (FrameBridge, suggested for Unity built-in OVRPlugin games): a located time nearer the monotonic clock than XrTime's "now" is moved by the clock offset measured at xrWaitFrame, one more than 0.5 s before the display time goes to "now" (log `pose_time_fix: …`; `pose_debug=1` counts both per 5 s). Once a build has this FrameBridge it is toggled in settings.conf (no rebuild) The offset is the largest of the last ~2 s of xrWaitFrame samples (hitches made single samples dip by up to 2.5 s and pushed fixed times into the future); far-past requests get the frame's display time. Headless survey of 54 games (2026-10-09): no head/view request on the monotonic clock in any other game; UE4 OVRPlugin 1.89 games (Robo Recall, Vader, Phantom, Time Stall) and The Room VR ask for head/views at XrTime ≈ 0 every frame, which works today; hands only show in the headset. Suggested for Unity built-in Oculus games only. A time equal (±1 ms) to one of the last 6 predicted display times is never moved, and monotonic times are only told apart when the clocks are more than 4 display periods apart and the time is clearly nearer the monotonic "now" (GitHub #49: on a Frame with XrTime only ~68 ms ahead, a display-time request after a hitch was moved +67.7 ms) |

+| Game crashes at start: `java.lang.NoSuchMethodError: No virtual method getAvailableCommunicationDevices()… in class Landroid/media/AudioManager` at `com.vivox.sdk.AudioChangeListener.checkAudioRouteAndApplyChanges` (for example Green Hell VR, GitHub #101); triage `vivox-api31` | Newer Vivox (voice chat) builds call Android 12 audio-routing methods without a version check; Lepton is Android 11. Older Vivox builds (Eleven Table Tennis, BattleSisters) don't have that code | `frame.vivox_audio_route` (suggested by analysis `vivox_api31`): every AudioChangeListener method that calls one of them returns at once (`Dex.return_early`: return-void / `const/4 v0, 0; return v0`, in place); voice chat keeps the default audio route |

+| Unity game hangs or the whole Frame restarts (for example in a menu); log: `The current MSAA level is 0, but the recommended MSAA level is 4. Switching to the recommended level.` (for example Lucky's Tale) | Meta's OVRManager (`useRecommendedMSAALevel`) turns 4x MSAA on at runtime, past QualitySettings; multisampled render-to-texture on GLES/Zink hangs the GPU | `frame.unity_runtime_msaa_off` (Cpp2IL: `OVRDisplay.get_recommendedMSAALevel` → 0) |
+| Unity game: one eye shows only effects or gray, the other is fine (for example I Am Cat, Oculus XR Plugin on GLES) | the game's single-pass multiview rendering goes wrong for array slice 1 (the adapter submits both slices correctly) | `frame.unity_multipass` (Cpp2IL: `OculusSettings.GetStereoRenderingMode` → MultiPass); `swap_eyes=1` tells whether the game or the adapter is at fault |
 | Setup/intro loops every launch (Espire 2) | save folders created without write permission | launcher repairs permissions every 2 s (built in) |
 | VrApi bridge: never enters VR | Frame reaches FOCUSED later than Quest; tracking only when worn | bridge waits 30 s; test in the headset |
+| Unreal game (ILMxLAB, for example Vader Immortal) plays its intro, then stays on its loading card (portrait + progress bar) at 72 fps and ignores input (GitHub #49) | the menu waits for `UVRUtils::GetQuestShaderPrecompilePercent()` to reach 100 %; the precompile only starts when `IsRunningOnSantaCruz()` (a Quest), the other branch returns 0.0 | `frame.unreal_quest_precompile` (non-Quest branch returns 1.0; found by Klownicle); suggested when the engine exports that function (analysis `unreal_quest_gates`) |
+| Video in a game or player stutters, falls behind or drops to a few fps (4K/8K, for example a video player's 360° video, Batman's cutscenes); `OMX.google.*` / `c2.android.*` decoders in the log | Lepton's Android has only software decoders | `frame.hw_video_decode` (suggested when the APK uses MediaCodec/ExoPlayer/VLC; no APK change, reinstall): `OMX.frameport.{avc,hevc,vp9}.decoder` on the Frame's Iris hardware (H.264 High, HEVC Main, VP9 profile 0 up to 4096x2304; 8-bit; up to 8192 px), mounted into this game's container only (log `Iris hardware video/… decoder active`; launch.log `FramePort video: loading the Iris hardware codec plugin`). `Iris … unavailable` / `initialization failed (-12)` (triage `hw-video-decoder-busy`): another decoder holds the hardware, usually Steam's own hardware video decoding: turn it off in Steam, restart Steam.

 ## Picture problems (headset on)
 | Symptom | Cause | Fix |
 |---|---|---|
+| Found after playing: the game page's "Last session" (or `frameport session <pkg>`) lists a finding (agent v70 `session_log`: the newest `plays.log` session's launch.log, ≤4 MB, + its crash logcat + kernel GPU lines) | launch tests never reach FOCUSED or gameplay; the same `catalog/triage.yaml` signatures (sync_guard, pac_hints, unreal_gl_shim, vk_spec_fixes, …) now also run on real sessions, plus the frame-rate and focus-dip findings below | "Try this setting" (FrameBridge settings: written on the Frame at once via `set_settings`, used from the next start) / "Rebuild with this patch" (APK patches); launch-test sessions (`test <unix>` in plays.log) are skipped |
+| Textures flicker, jump or smear while moving in an OVRPlugin game that renders space-warp swapchains (`xrCreateSwapchain 376x376 format=97` / `format=129`; triage `space-warp-used`, info + question) | Application SpaceWarp: half the frames plus motion vectors; the Frame's reprojection of them misbehaves (Into The Radius 2, Metro Awakening) | adapter `hide_space_warp=1`; offered as "Did textures flicker…?" after a play session, never applied on its own |
+| The game froze or closed and the kernel log has `hangcheck` / GPU fault / `msm_drm … recover` lines during the session (triage `gpu-hang`, play sessions only) | a shader or effect hangs the Frame's GPU (for example Vader Immortal's lightspeed jump) | capture the shaders (`adapter.vk_shader_dump=1` Vulkan, `adapter.zink_shader_dump=1` OpenGL ES: triage keeps the one matching the session's swapchain formats), play to the hang again and send a problem report (diagnostics carry the newest dumped modules); the maintainer adds a `vk_shader_fix` / `zink_shader_fix` catalog entry. `zink-device-lost` keeps its MSAA suggestions |
+| The game keeps pausing or recentring for a moment while worn (session finding `focus-dips`: ≥3 `focus: back after N ms` lines longer than the game's focus_hold_ms, up to 5 s) | the Frame's wear sensor flickers "HMD off"; FrameBridge logs every runtime focus loss/return (always, before focus_hold) | `adapter.focus_hold_ms=<longest dip + 250 ms, in 500 ms steps, ≤5000>` (or `adapter.focus_hold=1` when off) |
+| Judder or smearing on head turns; FrameBridge pacing below the display rate (session finding `slow-frames`: >30 % of the 5 s windows under 90 % of the nearest refresh rate ≥ the session's 90th-percentile fps, after the first two windows, ≥1 min) | the game renders below the refresh rate; the runtime reprojects | `adapter.scale=<current × 0.85>` first, then `frame.unity_runtime_msaa_off` (Unity) / `adapter.hide_space_warp` (Unreal 5 + OVRPlugin) |
+| Unreal game (ILMxLAB, for example Vader Immortal): controllers track but grip/trigger do nothing, grabbing never works (Unreal's own input values move, the game's stay 0) | `URPOCKeyMapManagerComponent` picks the Quest or the Gear VR key set by `IsRunningOnSantaCruz()`; on the Frame it takes Gear VR, empty in a Quest build | `frame.unreal_quest_keymap` (the Oculus case keeps the Quest set, for action and axis mappings; found by Klownicle, GitHub #49) |
+| The hands' thumbs never move when you touch the thumbstick or buttons (Unreal `ThumbUp` stays 1, for example Vader Immortal) | OVRPlugin reports thumb proximity from XR_FB_touch_controller_proximity, which the Frame's runtime lacks; OVRPort's loader offers it anyway and the proximity actions never get a binding | adapter `proximity_emul=1` (thumb proximity from the touch inputs: thumbstick, face buttons, thumb rest; 2 = also the index finger from trigger touch); log `proximity_emul: finger proximity bound to touch`. **For UE4 Oculus games this didn't animate the thumbs** (Vader, GitHub #49): use `frame.unreal_thumb_touch` (found by Klownicle): `OculusInput::FOculusInput::SendControllerEvents` computes ThumbUp from NearTouches (masks 0x2/0x8); the patch makes it read Touches (the slot 4 bytes before) with masks 0x0f00 (X/Y/stick/thumb rest) / 0x000f (A/B/stick/thumb rest), keeping the inversion; three instructions, matched exactly (build note `OculusInput ThumbUp: from the capacitive touches`). Matches Vader Immortal Ep. I, Robo Recall, Phantom: Covert Ops, Time Stall, Star Wars: Tales from the Galaxy's Edge; newer UE4 builds (for example Asgard's Wrath 2, RE4, In Death) compile it differently (shared mask registers) and aren't matched |
+| Vulkan game (Unreal / own engine with the Vulkan shim): the GPU hangs at one effect or cutscene (kernel `hangcheck detected gpu lockup`, freeze/exit; for example a VR4 cutscene, GitHub #140) | a SPIR-V shader reads a loop counter/accumulator before setting it (VR4's campaign shader, GitHub #10) | adapter `vk_shader_dump=1` (`frame.vk_sanitize`'s shim; log `vk shim: dumping SPIR-V modules to …`) writes every distinct module once to `files/fp_vk_shaders/<size>_<sha256>.spv` + `index.txt` (`<seq> <ms> <unix ms> <name> new\|known\|again`); play to the hang, collect diagnostics (`target/shaders/fp_vk_shaders/`, newest 4 MB) and take the modules first created (`new`) shortly before the kernel's hangcheck time; disassemble (`spirv-dis`), find the variable read before its first store, write a `vk_shader_fix` (`<size>:<sha256>:<byte offset>:<words>` = inserted OpStores; log `vk shim: fixed shader module`); switch the dump off again |
+| OpenGL ES game: the GPU hangs at one effect (freeze/exit, compositor watchdog, for example Vader Immortal's lightspeed jump) | a shader (as Zink compiles it) reads loop counters/accumulators before setting them | capture the SPIR-V (adapter `zink_shader_dump=1` writes every module to `files/fp_spirv/`, or a GPU capture), then a `zink_shader_fix` entry (same format as `vk_shader_fix`) + `frame.zink_shader_fix` (Vulkan layer under Zink, activated through GraphicsEnv's debug layer list); log `shader fix layer: fixed shader module N`; triage `zink-shader-fix-mismatch` when a Frame update changed the driver's output |
 | 2D Android app: Steam says it's running but nothing shows | Lepton runs apps headless unless the app folder has `lepton-show-flatscreen` | FramePort adds it for apps without VR (agent v28+); reinstall apps installed before |

Check: launch.log `FramePort gamepad: Steam Input virtual gamepads for this container: event5 (…)` ("none" = Steam had no pad when the game started: Steam only makes it while the controllers are on), `podman exec lepton-steamlaunch-<appid> dumpsys input` lists the pad.

+# Batman cutscene playback on Steam Frame
+
+Batman: Arkham Shadow (`com.camouflaj.manta`) submits its prerecorded cutscenes
+through Android video surfaces and stereoscopic 180-degree OpenXR equirectangular
+layers. Lepton/SteamVR's missing surface/layer support leaves those layers black,
+while the separately played audio continues. Uploading software-decoded panorama
+pixels also does not provide practical playback of the original 8192x4096 HEVC
+assets.
+
+## Scope and installation
+
+FrameBridge enables the native-video path through the recipe-only adapter
+setting `surface_native` (Batman's catalog recipe; a one-time library migration,
+`batman_video_patches`, adds it and `frame.hw_video_decode` to existing Batman
+recipes). Hardware decoding is deployed independently into FramePort's shared,
+versioned codec store, without embedding decoder assets; games that have
+`frame.hw_video_decode` in their recipe get the launcher line that places the
+shared wrapper on the launcher's child PATH. Matching containers
+receive read-only plugin/XML mounts and the Iris decoder device. Shared Lepton
+files and original MP4/OBB assets are
+never replaced, transcoded, resized, or rewritten.
+
+The native projection, view recording and Vulkan-enable hooks are gated by
+`surface_native`. With it off, Vulkan function lookup and directly exported
+entry points pass through to the original loader; default `surface_emul`
+alone does not enable the new Vulkan projection path. The fixture
+`tests/fixtures/src/surface_hooks_test.c` checks function identity with the
+setting off/on and direct-export forwarding with it off. Compile it with
+`FRAMEPORT_FAKE_RUNTIME` as `libopenxr_loader_original.so`, then without that
+define as the client; run each setting in a separate process next to the
+production adapter and fake loader.
+
+The wrapper verifies the tested Android 11 SoftOMX ABI. An existing runtime
+hardware plugin takes precedence; incompatible runtimes keep their stock codecs.
+Hardware decoder capacity is probed before the private component is advertised.
+If the driver's session limit is exhausted, Android can fall back to software
+decoding; that preserves functionality but not full-resolution performance.
+FramePort does not change Steam's global hardware-decoding settings.
+
+Other games don't get `surface_native`. The decoder is separate from that
+setting, and runs in Lepton's arm64 media service. Rebuilding an older APK
+removes the previously bundled codec files; launcher migration replaces
+Batman's old per-game wrapper with the shared one. MP4 presence alone is not
+evidence of compatible surface/overlay semantics.
+
+The recipe change marks Batman's installed build "Update on Frame"; the shared
+adapter revision is unchanged, so other games stay installed as they are.
+
+## Decode and render path
+
+`native/hevc/frameport_hevc.cpp` exposes `OMX.frameport.hevc.decoder` through the
+tested SoftOMX ABI, using FFmpeg's LGPL Iris V4L2 hardware decoder wrapper.
+Native surface clients receive full-resolution YUV hardware buffers with fences.
+Compatible large native surfaces use fenced Vulkan transfers between imported
+decoder and Android DMA buffers, retaining the decoded frame until GPU completion.
+Other surfaces retain parallel NV12 row copies without CPU color conversion.
+Input timestamps, EOS, dynamic dimensions, seek and flush
+are preserved.
+
+An AImageReader retains the decoder's actual image. The surface worker samples
+that original YUV buffer and fuses conversion with visible-view projection on
+the GPU. Vulkan imports the finished shared view with explicit foreign ownership
+transfers. There is no full-panorama RGB intermediate or CPU picture readback.
+The default native output is 2560x2560 per eye with a 12% tangent-space guard;
+an explicit `equirect_res` takes precedence.
+
+Every finished view carries the camera that actually generated its pixels.
+Submitted game projection views are preferred over another tracking query.
+The worker coalesces video/view arrivals and reuses held pixels only while the
+visible frustum remains covered. Color/source changes redraw content without
+unnecessarily changing the covered panorama-local sampling camera. Infinite
+panoramas retain their layer rotation and have no translational parallax.
+
+## Stable composition
+
+A separately submitted projected video layer can alternate with the main game
+projection as opaque coverage changes during head movement. That presentation
+path exhibited snap-back/doubled video in headset tests even when rendering
+and submitted camera metadata agreed.
+
+The native path instead snapshots the game's successfully waited stereo color
+image **before forwarding its release**, restoring its color-attachment layout
+after the copy. Acquisition indices are tracked in FIFO order. The application
+image is never sampled or modified after its OpenXR release, and release is not
+deferred. Snapshot generations must match the last successful release.
+
+The final GPU pass reprojects the cached video into the current game camera,
+blends it with the scene in linear light, and draws directly into a runtime sRGB
+attachment. One primary projection contains both scene and video, including
+fades and uncovered hemisphere edges. Later subtitles/menu layers keep their
+order. Once this output is ready, movie updates copy only to its private cache,
+avoiding the additional standalone-output copy.
+
+Batman attaches color-scale/bias and image-layout structures even when their
+transforms are identity. The compositor applies RGB/alpha scale and bias using
+OpenXR's straight-color transform and restored premultiplication, and respects
+vertical orientation. Unknown scene/view chains, unsupported layout flags, and
+intervening layers keep the ordinary fallback; settings are not silently lost.
+The push constants fit Vulkan's guaranteed 128-byte minimum.
+
+Each output image has separate commands, descriptors and fences. Positive wait
+timeouts retain acquisition for retry. Missing snapshots retain the previous
+combined output with the exact camera that produced it; old pixels are never
+relabelled with a newer pose. Teardown retires snapshot writers and compositor
+readers. Depth/motion-vector images from another render are not attached.
+
+## Building and validation
+
+Rebuild FrameBridge with Android NDK r27c:
+
+```sh
+python native/build.py --only adapter --ndk /path/to/android-ndk-r27c
+```
+
+The hardware plugin builder and its pinned source/runtime requirements are in
+`native/hevc/README.md`. Shader sources and their generated SPIR-V are included.
+Compile them for Vulkan 1.0 and validate with `spirv-val` when changing them.
+
+The host tests cover package-scoped settings/assets/freshness, existing-wrapper
+updates, codec extraction checksums, runtime/container isolation, and preservation
+of original video assets. Android fixtures in `tests/fixtures/src/` exercise the
+production Vulkan shaders, hardware worker, camera/coverage helpers and YUV copies.
+The original-8K worker test requires a lawfully supplied cutscene file and the
+private codec in an isolated Android container; no game assets are distributed.
+
+Validation on Steam Frame included stereo/fade/transparent/uncovered pixels,
+asymmetric vertical orientation, color/alpha transforms, unsupported-chain
+fallback, timeout retry, held camera metadata, reader teardown, hardware playback,
+pause/resume and seek. One isolated run presented 594/600 and 118/120 distinct
+scheduled original pictures, none early; 120 moving-head composition frames
+averaged 1.16 ms for submission plus GPU completion. These are isolated fixture
+results, not a guarantee of full-game frame rate.
+
+The final build was also tested in Batman in-headset: cutscenes displayed and
+head-movement snap-back was reported resolved. Logs confirmed the combined path,
+full-resolution hardware decoding, over 12,500 scene frames with only two startup
+holds, and no subsequent old promotion messages or composition setup failures.
+Some frame-rate dips and existing Unity render-pass warnings remain. The patch
+does not claim universal game compatibility, exact Quest 3 pixel equivalence,
+or perfect frame timing.

 | `platformcompat/` | `arm64-v8a/libovrplatformcompat.so` | Real `ovrMessageType_ToString` (same fork, `native/platform`). |
 | `langpack/` | `arm64-v8a/libfp_langpack.so` | Language packs for the Meta Platform SDK (patch `frame.langpacks`, opt-in). overport's platform loader is a dispatcher in front of Meta's own loader and answers `ovr_LanguagePack_GetCurrent/SetCurrent` with `return 0` (no reply ever). This library becomes the loader's first DT_NEEDED; the loader's own exports of the 31 functions it defines are made STB_LOCAL in `.dynsym` (`elf.hide_exports`, nothing moves), so symbol lookups reach the library first. It serves `<tag>.lang` files found in the game's OBB / app files (`$FRAMEPORT_LANGPACK_DIRS` overrides the search path) through `ovr_LanguagePack_*`, `ovr_AssetFile_GetList` (the loader's list + the packs) and `ovr_AssetFile_StatusById`; its own message queue is merged into `ovr_PopMessage`, and every handle that is not ours (an address-range check) goes to the loader's original function, whose address is read at run time from the loader's in-memory `.dynsym`. With patch `frame.asset_files` (marker byte `@FPASSETS@`, or env `FRAMEPORT_ASSET_FILES=1`) it also lists the data's `*.pak` content files as installed `default` asset files and answers `ovr_AssetFile_DownloadById` for them at once (a completed `DownloadUpdate`, then the result with the path). Host-tested against a stand-in loader (`tests/test_langpack.py`, plain `cc`, no NDK); the bionic/headset side is unverified. |
 | `glshim/` | `arm64-v8a/libglshim.so` | Mesa GLSL compatibility for GLAD engines (hooks eglGetProcAddress): comments out `#pragma` before `#extension`, enables `GL_EXT_shader_implicit_conversions`, hides GL_OVR_multiview (`gl_hide_multiview`, default 1) and logs failed shaders. `-DGLSHIM_TRACE` adds per-FBO draw/error tracing. |
+| `glmv/` | `arm64-v8a/libfpglmv.so` | Single-view draws of OVR_multiview programs (patch `frame.gl_multiview_fbo`, opt-in, GitHub #77). Mesa enforces OVR_multiview's rule that a draw's program declares as many views as the draw framebuffer has; engines that compile every shader with `num_views=2` and also draw into ordinary 2D framebuffers (Doom3Quest's HUD/PDA pool) lose those draws. The engine library gets it as first DT_NEEDED (direct `gl*` imports) and its `dlopen("libGLESv3.so")` string is rewritten to `libfpglmv.so` (same length; its `qgl*` dlsym table); linked `--no-as-needed` to libGLESv3 so dlsym on its handle finds everything it doesn't wrap. It records stage sources at glLinkProgram, caches the draw framebuffer's color-attachment view count per bind, and when a multiview program draws into a 0-view framebuffer it binds a lazily built twin (`glmv_rewrite.h`: num_views layout blanked, `gl_ViewID_OVR` -> `(0u)`; attribute locations + uniform block bindings copied, default-block uniforms copied before every such draw with a shadow to skip unchanged ones), draws, rebinds the original. Logcat tag `GLMV`; `gl_mv_debug=1`. The rewriter is host-tested on Doom3Quest's 19 shaders (`tests/test_gl_multiview_fbo.py`); untested on the device. |
+| `zinkfix/` | `arm64-v8a/libVkLayer_fp_shaderfix.so` | Shader-fix Vulkan layer `VK_LAYER_FP_shader_fix` for OpenGL ES games (patch `frame.zink_shader_fix`): sits between Zink (Mesa's GL on Vulkan) and the driver and inserts the words of `zink_shader_fix` (same format as the Vulkan shim's `vk_shader_fix`: size + SHA-256 match) into SPIR-V modules; `zink_shader_dump=1` writes every distinct module to `files/fp_spirv/`. The engine library loads it first (DT_NEEDED); its constructor puts the layer in front of Android's GraphicsEnv debug layer list (private Android 11 `getDebugLayers`/`setDebugLayers`, found through libvulkan.so's dependencies) before EGL starts, so the loader picks it up from the app's lib dir. Exports only the enumeration functions and `VK_LAYER_FP_shader_fixGet*ProcAddr` (never plain `vk*` entry points). Vader Immortal's lightspeed shaders (Klownicle, GitHub #49). |
 | `xrlayer/` | `linux-arm64/libxr_frameport_timefix.so` + `XR_APILAYER_FRAMEPORT_timefix.json` | OpenXR API layer for Windows PC VR games under Proton on the Frame (glibc aarch64, built freestanding with the NDK's clang), on by default (patch `pcvr.xr_timefix`). Retries `xrCreateInstance` as an OpenXR 1.0 app when the runtime rejects 1.1 (the Frame's SteamVR runtime does, and Proton 11's VR helper asks for 1.1). Also emulates `xrConvertTimespecTimeToTimeKHR`/`xrConvertTimeToTimespecTimeKHR` if the runtime refuses them (the Frame's Android runtime does; its Linux runtime, used by Proton, supports them as of 2026-09-29 — so this part is only a fallback; Proton's wineopenxr needs them for `XR_KHR_win32_convert_performance_counter_time`, which Revive requires) with the adapter's xrWaitFrame-calibrated offset, and drops the extension from xrCreateInstance if the runtime rejects it. Enabled per game by the Proton launch.sh (`XR_API_LAYER_PATH`, `XR_ENABLE_API_LAYERS`). `tests/test_xrlayer.py` builds it for x86_64 and drives it via ctypes. |
 | `oculushmd/` | `win-x64/fp_oculushmd.exe` | PC VR counterpart of overport's `patch_oculus_unreal` (patch `pcvr.oculus_unreal`, default for Unreal Rift games on the Frame). Unreal's OculusHMD and LibOVR's `ovr_Detect` only start when the Windows named event `OculusHMDConnected` exists and is signalled (the Oculus service creates it). `fp_oculushmd.exe <command line>` creates it (manual reset, signalled), runs the command (Revive's injector) in a job object and keeps the event until every process in the job — the game and its children — has exited (fallback without job support: 3 minutes); returns the command's exit code and logs `FramePort oculushmd: …` to stderr (launch.log). Freestanding Windows x64 console exe (no CRT, no Windows SDK): the NDK's clang + `lld-link /Brepro` with a kernel32 import library generated by `llvm-dlltool`, so it's byte-reproducible. Tested on Windows from WSL with a build whose event name is `-DEVENT_NAME=L"…"` (the Oculus service owns the real event on a PC with the Oculus app). |
 | `xrshim/` | `arm64-v8a/libframe_xrshim.so` | FrameBridge extension shim, only in builds with `controller_models=1`. overport's dispatcher (`libopenxr_loader.so`) answers `xrGetInstanceProcAddr` from a fixed table and refuses everything else (`overportOXR: Unknown proc addr: xrLoadRenderModelFB`), so the adapter never sees XR_FB_render_model lookups. Meta's OVRPlugin gets the function with `dlopen("libopenxr_loader.so")` + `dlsym`, so FramePort rewrites that `.rodata` string in `libOVRPlugin.so` (same length, in place) to `libframe_xrshim.so`. The shim returns the adapter's emulated functions (`framebridge_extension_proc`) and forwards every other name to overport. A DT_NEEDED interposer does not work here (dlsym on a handle searches that library first); tried and dropped. |
