 ## Unreleased

- Fix smoke cleanup skipping orphan metadata and Steam shortcuts after a test
-  title directory was already removed. Sweep and verify all six exact reserved
-  smoke IDs; preserve similarly named titles. Make `scripts/frame-smoke.sh`
-  work with POSIX sh and Python 3 without zsh, including from another working
-  directory. Local regressions cover both fixes; no new headset run.
-
- Skip backup saves and settings reached through a symbolic link anywhere below
-  the home folder, and recheck paths before packing each file. Local synthetic
-  tests cover redirected Proton prefixes and links changed after discovery;
-  concurrent filesystem changes can still race the checks.
-  [Backup layout and limits](docs/backup-and-recovery.md).
-
- Import a base APK with supported native-library or asset splits from a local
-  Android backup or XAPK/APKS/APKM bundle. Check package and version before
-  install; refuse resource, code and feature splits and device-variant sets.
-  This route has local fixture coverage, not a real split-game headset test.
-
- Save Steam screenshots under a separate folder for each headset, Steam
-  account and game. Equal screenshot filenames no longer overwrite one another;
-  existing files in the old flat folder are left in place.
-  [Copying guide](docs/recording.md).
-
 - Compare two explicit Windows Wireless Adapter doctor reads in local memory.
  Highlight exact PnP instances and known state changes after a dropout;
  incomplete inventories stay unknown. A Forget button clears the comparison.

-**Optional: open at login.** In the installed desktop app, choose **Frame → Open at Login**. It is off by default. When on, a login launch starts in the tray or menu bar if that control is available; click its icon to open the window, or use its **Quit Frame Control** menu item. Closing the window keeps the app in the tray while this option is on. Turn the same menu option off to remove its OS login item. On Linux this creates or removes only Frame Control's own file in `~/.config/autostart/` (or `$XDG_CONFIG_HOME/autostart/`). If the desktop has no working tray, the window opens at login instead.

-# Connection and streaming lag FAQ
-
-## Does Frame Control lower my streaming lag?
-
-No. Frame Control uses SSH to manage the Frame. SteamVR or Steam Link sends the
-game stream. Frame Control does not carry the game stream. It cannot lower your
-game-stream ping or fix a stream that stops on the PC. A 40–75 ms ping in a VR
-game is not a Frame Control measurement.
-
-You do **not** need the Steam Wireless Adapter to use Frame Control. The app can
-connect over Wi-Fi, the Wireless Adapter, or USB if the computer has an SSH
-route to the Frame. Use the route that lets the app connect. To improve game
-streaming, check the SteamVR or Steam Link connection on the PC and the Frame.
-The [wired connection doctor](wired-connection.md) checks only Frame Control's
-SSH route. A successful doctor check does not prove that the game stream uses
-the cable or has low lag.
-
-## Can I use a USB-A-to-C cable?
-
-A Mac reached the Frame over a USB-C connection on the
-`10.86.200.232/29` USB network. That test used a USB-C host port. We have
-**not tested a USB-A-to-C cable** with the Frame. A data-capable USB-A-to-C
-cable might show a USB network interface on your PC, but this is unknown on
-the tested Frame OS and PC hosts. Check whether your PC shows that interface
-and whether Frame Control's wired doctor can reach the Frame at
-`10.86.200.233`. A charge-only cable cannot carry USB data. You can use Wi-Fi
-for Frame Control if the USB route does not work.

-# Decky Loader on Steam Frame
-
-For the modding-path survey, licence review and update limits, see
-[plugin and modding research](plugins-research.md).
-
-**Status, 2026-10-25:** Decky Loader 3.3.0's ARM64 backend starts on Frame OS
-0.5.6 and injects into Steam's shared CEF context. Its Decky tab registers in
-JavaScript. A usable plugin menu in the Frame's VR shell has **not** been
-verified. Frame Control therefore labels its user-service manager experimental.
-ProtonDB Badges loaded in the backend and Gamepad UI plugin registry, but its
-VR user interface has not been seen or used.
-
-## Official store plugin audit, 2026-10-25
-
-On a real Frame with Frame OS 0.5.6 build `20261022.6153909`, SteamVR 2.18.2
-reported `activity_level` 3 (standby). The battery was 99% before and after.
-The test downloaded the official store's current archives, checked each SHA-256
-against store metadata, and inspected their manifests and binaries. For seven
-non-root candidates, the removable user-service loader started each plugin in
-turn. It stopped between plugins. Logs showed `Loaded <name>` for all seven.
-The service and test folders were removed after the run; the owned shared lock
-was released. **A load message is not proof that a plugin's page, settings, or
-action works in VR.** No plugin was tried by a wearer.
-
-| Official store plugin (tested version) | Result | Evidence and limit |
-| --- | --- | --- |
-| ProtonDB Badges 1.3.4 | Partial | ARM64 backend loaded. Earlier 1.1.0 also registered in the shared Gamepad UI; badges in the VR shell were not seen. |
-| CSS Loader 2.1.3 | Partial | Backend loaded; one `SyntaxWarning`. Theme controls and CSS application in VR were not checked. |
-| SteamGridDB 1.8.1 | Partial | Backend loaded. Artwork selection and its UI were not checked. |
-| Animation Changer 1.3.2 | Partial | Backend loaded. Boot animation replacement was not attempted. |
-| Storage Cleaner 1.4.0 | Partial | Backend loaded. No files were cleaned; no UI check. |
-| HLTB for Deck 2.0.12 | Partial | Passive plugin loaded. Game page content in VR was not checked. |
-| Bluetooth 3.1.1 | Partial | Backend logged `Bluetooth plugin loaded`. Pairing and VR controls were not checked. |
-| PowerTools 2.0.3 | Not applicable | Manifest asks for root; archive includes x86_64 Ryzen binaries and targets Steam Deck hardware. The Frame user service blocks it. |
-| Audio Loader 1.6.1 | Not applicable | Manifest asks for `_root`; the Frame user service blocks it. |
-| Wine Cellar 0.2.1 | Broken on ARM64 | Archive includes an x86_64 backend binary. The store installer blocks it before execution. |
-| MagicPods 2.0.21 | Broken on ARM64 | Archive includes an x86_64 `magicpodscore` binary. The store installer blocks it before execution. |
-| Decky Recorder | Not in current official store | No matching plugin appeared in the official store list on this date; no archive was installed. Frame Control's own headset panel has a separate recorder. |
-
-The table reflects the tested versions only. Other releases can change their
-files or behavior. The official store's digest checks the archive in transit;
-it does not certify plugin code. Plugins run with the headset user's access.
-For a new plugin, follow the [Frame plugin and extension guide](frame-plugin-author.md).
-
-The new store transaction was also exercised on the same real Frame:
-**managed loader install → ProtonDB Badges 1.3.4 store install → status →
-store update → store remove → managed loader remove**. Status reported the
-managed store ID and version while the plugin was installed. The service
-remained active after each store change. The battery was 99% before and after.
-The test removed its plugin folder, loader, and owned lock. This validates the
-store file and service path over SSH, not a visible VR plugin page.
-
-Frame Control's desktop app and opt-in headset panel now show official store
-entries. Install, update, and remove need an explicit confirmation. They only
-change Frame Control owned plugin folders under
-`~/.local/share/frame-control/decky/plugins`. The installer checks the store
-hash and archive paths, blocks root plugins and non-ARM64 binaries, and rolls
-back an update if the service restart fails. The current VR shell does not
-provide Decky's Steam Deck Quick Access Menu. Frame Control's headset panel
-shows installed plugins and store actions, but plugin pages, settings, routes,
-and Decky toasts are **not** available there yet. The panel itself still needs
-a worn-headset visual and controller check.
-
-## What was checked on the real headset
-
-The headset was SteamOS `0.5.6`, `VARIANT_ID=vr`, build `20261022.6153909`,
-`aarch64` (SteamOS 3.9.x family). SSH reached it through the existing `frame`
-alias. `/` was mounted read-write as Btrfs; no root filesystem change was
-needed. `systemctl --user` was running. The Steam client launched with
-`-cef-enable-debugging`, `-vrgamepadui`, and `-steamdeck`; its web helper served
-CEF remote debugging on `127.0.0.1:8080`. The usual
-`.cef-enable-remote-debugging` marker was absent, yet debugging was active.
-
-CEF listed a `SharedJSContext` target at `steamloopback.host/routes/library/home`
-and a separate `SteamVR` target for the VR overlay. The Decky 3.3.0 ARM64
-binary started from `/tmp` as the normal user: port `127.0.0.1:1337` answered
-HTTP 200, the log reported `Loading Decky frontend!`, and CEF showed
-`window.deckyHasLoaded === true` and one registered Decky tab in
-`SharedJSContext`. The `SteamVR` target had neither that global nor a Decky tab;
-its current body text did not contain Decky. The Steam web helper had
-`--disable-quick-menu`. This is evidence of backend and shared-context
-injection, not proof of an accessible Decky plugin menu inside VR. A QAM
-interaction in the headset and a plugin UI test remain necessary.
-
-Frame Control's per-user manager was then exercised on the real Frame:
-**install → status → update → status → remove → status**. The service became
-active, the binary matched Decky's published SHA-256, and removal left no
-service, binary or listening port 1337. Decky's already injected JavaScript
-remained in Steam's running web helper until that helper was restarted. After a
-web helper restart, both `deckyHasLoaded` and the tab hook were absent. All
-temporary trial files and the test's empty managed data folder were removed.
-
-## ProtonDB Badges compatibility test
-
-The [ProtonDB Badges v1.1.0 release](https://github.com/OMGDuke/protondb-decky/releases/tag/v1.1.0)
-was tested on the same Frame OS build. It is a popular, passive Decky plugin
-(133 GitHub stars at test time) that adds badges to game pages. The published
-archive SHA-256 was
-`b4c72ff0ffe60b1a14abafe75a62f644cbb6689f398a753a1905c281151d9173`.
-Its six archive entries had no links or path traversal, and its manifest declared
-`flags: []` and `api_version: 2`. The release contains a frontend bundle and
-no backend `main.py`; its source backend only manages its own settings.
-
-The test copied the archive into Frame Control's managed Decky plugin folder,
-then installed the official Decky 3.3.0 ARM64 binary as a user service. Decky's
-log said `Plugin ProtonDB Badges is passive` and `Loaded ProtonDB Badges`.
-`DeckyPluginLoader.plugins` in Steam's `SharedJSContext` contained
-`ProtonDB Badges`; `deckyHasLoaded` was true there. The separate `SteamVR`
-CEF target had no Decky globals or plugin text, and SteamVR listed no Decky
-overlay. The headset was in standby, so no in-headset plugin page or badge
-interaction was verified. The backend's unauthenticated root URL returned
-HTTP 403, as expected.
-
-The test removed the managed Decky service and binary, the test plugin folder,
-and its shared-device lock. The service was no longer running, the plugin list
-was empty, the binary and unit were gone, and port 1337 was closed. Decky's
-already injected frontend may remain in the running Steam web helper until
-Steam normally restarts; the test did not restart Steam or SteamVR.
-
-## Why the official Decky installer is not used
-
-The current [Decky installer](https://github.com/SteamDeckHomebrew/decky-installer/blob/e42a3c828de90673959b4de26cf5c5d2c7830554/cli/install_release.sh)
-selects `PluginLoader-arm64` on `aarch64`, creates `~/homebrew/plugins`, writes
-the CEF marker, installs `/etc/systemd/system/plugin_loader.service`, and uses
-`sudo systemctl` to enable a **root** service. Its
-[uninstaller](https://github.com/SteamDeckHomebrew/decky-installer/blob/e42a3c828de90673959b4de26cf5c5d2c7830554/cli/uninstall.sh)
-also uses sudo. These scripts do not call `steamos-readonly`, but they do write
-under `/etc`; their root service has broad control over the headset. The
-current [Decky loader](https://github.com/SteamDeckHomebrew/decky-loader/blob/00cd202872b85868071b041c8f1b34e734147195/backend/decky_loader/injector.py)
-targets Steam's shared Gamepad UI CEF page, injects a frontend served on port
-1337, and patches the standard Quick Access Menu. On Frame, Steam supplies
-the CEF target, while visible VR shell integration is unresolved.
-
-Frame Control downloads only Decky's official latest ARM64 release, requires
-its published SHA-256 digest, and checks the ELF architecture. It installs a
-**user** service named `frame-control-decky.service` in
-`~/.config/systemd/user`, with the binary and plugin folder under
-`~/.local/share/frame-control/decky`. It never asks for a sudo password, edits
-`/etc`, or changes CEF flags. Decky warns that running without root is not
-officially supported. Plugins that require root, assume `~/homebrew`, or rely
-on Steam Deck hardware may fail even if the loader runs. Frame Control lists
-plugins already present in its managed folder and the upstream `~/homebrew`
-folder. The opt-in store manager installs compatible archives only into its
-own folder. It cannot make Steam Deck QAM plugin pages visible in Frame VR.
-
-The latest tested release was
-[Decky 3.3.0](https://github.com/SteamDeckHomebrew/decky-loader/releases/tag/v3.3.0),
-`PluginLoader-arm64` SHA-256
-`8ef5dcf36cbbbb6e97201a6baed5d79c4cc44ec27789fc9af1c5b6ae8f0b25b6`.
-This digest comes from that release's GitHub API asset metadata; it detects a
-download mismatch, but is not an independent signature.
-
-## Opt in and remove
-
-In Frame Control, open **Tools → Decky Loader on Frame**, read the experimental
-notice, check the acknowledgement box, and choose **Install**. **Update**
-downloads and verifies the latest ARM64 release again. **Remove managed
-Decky** disables and removes only Frame Control's user service and binary.
-It preserves plugin files and settings so unrelated user data is not deleted.
-Open **Official plugin store** to review a plugin, then confirm each install,
-update, or remove. Root and x86-only plugins are blocked. The manager only
-removes plugin folders that it installed; it leaves other Decky folders alone.
-Restart Steam or the headset to clear the frontend already injected into its
-current web helper process. No action wipes the headset.
-
-Manual removal if Frame Control is unavailable:
-
-```sh
-ssh frame 'systemctl --user disable --now frame-control-decky.service; rm -f ~/.config/systemd/user/frame-control-decky.service ~/.local/share/frame-control/decky/PluginLoader ~/.local/share/frame-control/decky/.frame-control/receipt.json; systemctl --user daemon-reload; systemctl --user reset-failed frame-control-decky.service'
-```
-
-That command intentionally keeps `~/.local/share/frame-control/decky/plugins`
-and `settings`. Check those folders before deleting them yourself. An upstream
-Decky installation is separate; use its own installer to remove it. Frame
-Control refuses to install alongside an upstream system service.
-
-## Next compatibility test
-
-In the headset, open Steam's VR dashboard and look for Decky's plugin tab or
-Quick Access Menu after an opt-in install. If none appears, inspect whether
-the VR shell exposes a different menu component and whether Decky's frontend
-can target it without patching Steam globally. Confirm the plugin's visible
-UI, controller interaction, and persistence across a normal Steam restart.
-Until those checks pass,
-Frame Control should not describe Decky plugins as usable in VR yet. A worn
-headset check is needed for both the Decky menu and the Frame Control SteamVR
-panel; only then can their controller interaction and plugin presentation be
-confirmed.

-# OBS relay and MP4 follow-up, 25 October 2026 UTC
-
-This check used a Linux x86-64 host (`lxso2`) and the real Frame running
-SteamOS 0.5.6, build `20261022.6153909`. The host reached `ssh frame`. Before
-device work, the task atomically acquired `/tmp/frame-test.lock`, wrote its
-owner marker, and after cleanup removed only that marker and its lock. Battery
-was 99–100%; SteamVR 2.18.2 reported `activity_level: 3` (standby). Steam and
-SteamVR were left running. No passthrough session or game was started.
-
-The production `scripts/obs-headset-source.py` relay reached its first local
-UDP packet in 0.65–1.15 seconds across several runs. A 12-second wall-clock
-capture of its MPEG-TS packets contained 325 H.264 frames at 1280×720,
-spanning 10.83 seconds of video timestamps: 30.0 fps. All 324 adjacent frame
-intervals were 33.333–33.334 ms, with none over 50 ms. The 826 captured TS
-packets had zero sync-byte, transport-error-indicator, or per-PID continuity
-errors. Six final TS packets arrived after the receiver's 12-second cutoff and
-were not included in those counts. Static standby pixels cannot establish
-whether a moving game would drop frames.
-
-After the fix, the `--height 1080 --fps 60 --no-audio` fallback reached its
-first packet in 0.597 seconds. An eight-second wall-clock capture contained
-447 H.264 frames at 1920×1080 over 7.45 seconds of video timestamps: 60.0 fps.
-All frame intervals were 16.666–16.667 ms, none over 25 ms, and its 756 TS
-packets had zero continuity or transport-error-indicator errors. It had no
-audio stream, as requested. The helper exited 0 on Stop, and the owned lock
-was released.
-
-The stream also contained 48 kHz stereo AAC. A 440 Hz synthetic tone played
-through the Frame's default speaker output with real-time pacing appeared in
-the capture for about 0.89 seconds; decoded audio had a -21.0 dB peak. This
-proves an audio signal reached the output monitor and OBS transport. It does
-not prove audible monitoring, real game audio, or audio/video sync: there was
-no simultaneous visible marker to compare with the tone.
-
-The production MP4 recording commands were run separately for six seconds,
-then Stop, remux, and copy to the host completed. Stop returned after 7.27
-seconds from Start, including six seconds of recording; the remote ffmpeg
-exited 0. The copied 36,929-byte MP4 contained 188 H.264 frames at 1920×1080
-and 30 fps (6.266 seconds), plus 281 AAC packets (5.994 seconds). One decoded
-frame at two seconds had a single color, RGB `(22, 27, 53)`, across all
-2,073,600 pixels. The test's remote files were removed; the host copy stayed
-under `/tmp` for inspection.
-
-The relay previously returned an error when the app deliberately closed its
-control pipe, because its SSH child commonly exits 255 after termination.
-The same test reproduced this (`helper_exit: 1`) on the real Frame. The follow-up
-fix recognizes deliberate Stop and adds bounded startup and stall timeouts,
-with fake-SSH regression tests. A new locked real-Frame check after the fix
-received its first 1,316-byte UDP datagram in 0.697 seconds and returned
-`helper_exit_after_stop: 0` after closing the app control pipe. The longer
-transport and MP4 measurements above were taken before the code change; the
-fix does not alter codecs or capture commands.

-Prior [OBS 30 Media Source evidence](obs-media-source-real-2026-10-25.md)

-# SteamOS PC OBS host feasibility check, 2026-10-25 UTC
-
-The available x86_64 host, lxso2, runs Ubuntu 24.04.3. It has no `flatpak`

-`42d774653c69b193c3d577743c32b8fe8dfeee7ea1f8cdf7369902962d647b83`.
-With `APPIMAGE_EXTRACT_AND_RUN=1`, it launched under Xvfb using an isolated
-profile and its bundled server returned HTTP 200. FUSE mounting, physical
-display rendering and SteamOS-specific dependencies were not tested.
-
-The v0.4.27 tagged OBS helper then ran against the real Frame under the shared
-`/tmp/frame-test.lock`. Frame OS was 0.5.6 and SteamVR activity level was 3
-(standby). A receiver bound to `127.0.0.1:15099` on lxso2 accepted 497
-MPEG-TS packets, 93,436 bytes. Every datagram had complete 188-byte packets

-## Environment and provenance
-
- Host: lxso2, Linux x86_64. Real OBS 30.0.2 in disposable Ubuntu 24.04/Xvfb,
-  using software llvmpipe rendering and the Media Source `ffmpeg_source`.
- Frame: SteamOS 0.5.6, build `20261022.6153909`, SteamVR 2.18.2, reachable
-  with the existing `ssh frame` connection. Hardware use was serialized with
-  coordinator mppkd9qczt through `/tmp/frame-test.lock` and a unique owner.
- Released v0.4.30 AppImage SHA-256:
-  `b1335bb06130f2cce64a0dd40a8cb60a52c68effc258dc4bc35f8c40c822d5bb`.
-  The long recording started through this app's actual Electron IPC, Python
-  helper and SSH stream. Robustness checks then used that released runtime
-  with the final changed resources and repacked `app.asar`; this was not a
-  newly built AppImage. No OBS plugin or host FFmpeg is required by the app.
- Windows release ZIP SHA-256:
-  `a393cc1653f14f162b4a3e56803f7fe9bea7b04904d18577b0b2d7d7c2d95b03`.
-  Checked against release SHA256SUMS; bundled Python 3.12.14.
-
-Machine-readable measurements and the manual stimulus/analysis programs are
-in [obs-validation-2026-10-25/](obs-validation-2026-10-25/).
-Room images and videos remain private under `/tmp/obs-aacapv3evh` on lxso2;
-only their hashes are committed in `private-artifacts.json`.

-| --- | --- | --- |
-| Real OBS recording | 187.367 s; 15,784,412 bytes; H.264 1280×720 at 30 fps; 5,621 decoded video frames; AAC 48 kHz stereo | More than three minutes through the packaged Linux path |
-| OBS dropped frames | 0 encoder skips; 90 render lag/stall frames, approximately 1.6% of recording frames | The software-rendered host was not lossless; this is not a hardware-rendered performance benchmark |
-| Audio | 1 kHz stimulus; FFT peak 996.094 Hz at 11.719 Hz bin resolution; peak −13.207 dBFS; 0 clipped samples; measured harmonic energy −81.32 dB relative to fundamental | Non-silent, no numerical clipping or large harmonic distortion in the checked tone; no listening or real-game quality verdict |
-| Baseline A/V | Audio leads video by median 426.67 ms; range 360–426.67 ms across 36 pulses | Default OBS setup needs sync checking; not suitable for a claim of automatic accurate sync |
-| Live image latency | 1,431.4 ms, n=1; clock exchange RTT 3.409 ms; screenshot polling about 20–35 ms | Overlay submission to OBS source screenshot, not physical headset motion-to-photon latency |
-| Production MP4 | 5.121 s; 1920×1080, 30 fps, 153 video frames; AAC stereo; request to saved result 7.435 s | A separate production recorder saved room passthrough pixels too |
-
-The manual stimulus places an owned black/white OpenVR marker over the mirror
-and plays a 200 ms, 1 kHz tone every five seconds through the Frame's default
-output. `pa_simple_get_latency` estimates when the submitted samples play;
-marker submission is aligned to that estimate. This measures software output,
-not an externally measured loudspeaker/physical-display event. Most submission
-jitter was below 0.2 ms; compositor timing and the 30 fps/10 ms analysis grids
-still limit precision. FFmpeg decodes both tracks; the analysis detects marker
-edges and groups AAC pre-echo onsets within 100 ms.
-
-A separate initial +400 ms OBS Sync Offset trial left 83.33 ms of audio lead.
-Changing the offset during an already active source from 0 to +367 ms did not
-improve that run (366.67 ms before, 370 ms after). Do not assume a universal
-offset or that a live setting change has taken effect: reopen the source and
-verify another recording. Three subsequent fresh-source trials, setting the offset **before activating**
-the Media Source, measured 480 ms audio lead at 0 ms, 70 ms lead at +400 ms,
-and **0 ms at +480 ms** across three pulses (30 fps video and 10 ms audio
-analysis resolution). This proves a setup-specific workaround, not a universal
-default. See `calibration-initial.json`. Full trial measurements are retained. Zero OBS
-buffering caused missing/distorted sound and was rejected. Zero mux delay
-and alternate timestamp experiments did not improve latency and were not
-merged. The default capture/encoding settings remain unchanged.

-## Robustness and fixes
-
-| Failure or scenario | Fix / result | Proof |
-| --- | --- | --- |
-| Stop during asynchronous Python discovery could still launch later | Cancel the pending generation; expose Stop while starting | Controller regression test |
-| Late stderr containing an earlier ready message changed stopping back to running | Only accept ready while starting; ignore stale child events | Original released block reproduced in `race-before.json`; controller regression |
-| A non-responsive SSH process defeated timeout termination | Bounded terminate/wait then kill; SSH connection/keepalive bounds | Real SSH child deliberately stopped with SIGSTOP; clear UI failure in 15.009 s including 5 s forced cleanup; both processes gone |
-| Timeout with the app's stdin still open aborted Python at shutdown | Read the control descriptor directly, avoiding a blocked buffered-stdin daemon lock | Previously reproduced fatal shutdown; final real stall shows `The Frame OBS video stopped for 10 seconds`; subprocess regression holds stdin open |
-| Three Start/Stop cycles | First packets 0.890 / 0.701 / 0.709 s; Stop to idle 61.7 / 52.7 / 53.0 ms | Final patched packaged runtime, ports 15101–15103, `robustness.json` |
-| Restart after stall | First packet 0.691 s | Same runtime and real Frame |
-| Quit while streaming | No surviving helper at 2.021 s | Same runtime; final audit found no test FFmpeg/stimulus process |
-| Port 15099 occupied | App now offers a validated alternate port and matching copyable URL | OBS occupied 15099 while real packets arrived on alternate ports; UDP cannot identify or guarantee the receiver |
-| OBS before/after Start; receiver restarts | Live decoding verified, including recreated sources while relay stays active; an already-open stalled receiver may need hide/show or properties OK | Documented recovery, not automatic OBS control |
-| Standby/wake | Safe wake changed a blank mirror to visible room/panels | Private mirror and saved recordings |
-
-A forced SSH stall tests the transport failure and error/cleanup behavior.
-It does **not** prove real Wi-Fi loss or full headset suspend/resume. No physical
-network interface was disabled and no headset reset was performed. There is
-no automatic reconnect: restore connectivity and press Start. Valid blank
-standby frames do not trigger a packet timeout.
-
-## Windows and macOS
-
-**Windows controls remain hidden.** A disposable Windows 11 VM ran the final
-helper using the released app's bundled Python and a native executable SSH
-fixture. It stayed alive for three seconds without a UDP receiver, then sent
-1,316-byte packets when a receiver opened. Closing its control pipe returned
-exit 0 with no surviving SSH child (`windows-pipe.json`; stop measured below
-the VM timer's resolution in the final run). The helper hides the SSH console
-and tolerates Winsock's delayed UDP receiver-unreachable error.
-
-The real-headset Windows attempt delivered zero packets through a temporary
-host SSH bridge. Native Windows OBS, direct Windows-to-Frame SSH, firewall
-behavior and packaged app Start/Stop have therefore not passed end to end.
-No local FFmpeg was installed; encoding belongs on the Frame. No firewall
-exception, headset authorized key, or Windows scheduled task was installed.
-
-**macOS:** no physical Mac or macOS VM was available. Python tests and the
-five controller lifecycle tests run in the macOS CI matrix; these cannot
-establish capture performance, audio quality, packaged launch or OBS behavior
-on a physical Mac.
-
-## Validation and remaining limits
-
-Local suite: **1,514 Python tests passed, 16 skipped**, 46 app tests and 18
-site tests passed. The latest helper additionally passed all 11 focused OBS
-tests; the controller passed all five focused lifecycle tests. Cross-platform
-CI results belong to the linked PR, not these host measurements.
-
-Still unverified: perceptual listening, real-game audio routing, accurate
-default A/V sync, broad latency/performance across hosts, hours-long sessions,
-physical Wi-Fi drop/full suspend recovery, physical macOS and native Windows
-OBS. The app/docs now explain copyable URL/format, receiver recovery, port
-selection, passthrough privacy and OBS Virtual Camera's video-only limit.
-The Discord guide provides the corresponding audio-sharing choices.
-
-Cleanup completed: Steam and vrcompositor remained running, battery 98%,
-no test FFmpeg/stimulus process remained, UDP ports 15099/15101/15102/15103/15105
-were bindable, task guest SSH config and the temporary bridge were removed,
-and the owned headset lock was released. The disposable Windows VM was
-stopped with its disk retained. See `cleanup.json`.

-# Screenshot Save on a real Frame, 25 October 2026
-
-After PR #192 merged, Frame Control's production `list_shots()` and
-`save_shots()` paths were run from lxso2 against the real Frame. The test held
-the shared `/tmp/frame-test.lock` with an owner marker and removed only its own
-lock. A separate locked check earlier in this round found SteamVR at activity
-level 3 (standby). No new screenshot was created.
-
- The Frame listed seven existing Steam screenshots.
- One existing screenshot was copied to a temporary folder on the PC. Its
-  local size matched the reported remote size: **294,885 bytes**. The new
-  destination had four components below the temporary root: headset, Steam
-  account, game ID and filename.
- Saving the same screenshot a second time returned zero new copies. A fresh
-  list then marked that screenshot as saved.
- The temporary PC folder and its private image were removed at the end. The
-  source screenshot on the Frame was only read. Battery was **100% Full**
-  before and after.
-
-This verifies one real screenshot transfer and the repeat-save behavior. It
-does **not** reproduce two different real screenshots with the same filename;
-the account/game/headset collision case is covered by the fake-source test in
-`tests/test_shot_copy.py`. Windows and macOS physical-PC saves were not tested.
-Active passthrough in the recording mirror remains unknown because the Frame
-was in standby.

-# Frame Control extensions
-
-Extensions add a local panel to Frame Control's Tools page. They are plain HTML,
-CSS and JavaScript. Frame Control discovers them from its per-user data folder;
-there is no build step, server process, or headset installation. Open an extension
-to run it. Closing it unloads its page.
-
-## Install the example
-
-Copy [`examples/extensions/headset-glance`](../examples/extensions/headset-glance)
-to the `extensions` folder shown on Tools → Extensions, then select **Refresh**
-and **Open Headset Glance**. The folder is normally:
-
- Linux: `~/.local/share/frame-control/extensions`
- macOS: `~/Library/Application Support/Frame Control/extensions`
- Windows: `%APPDATA%\Frame Control\extensions`
-
-To remove it, close the panel and delete only its `headset-glance` folder. The
-desktop app reads the folder on its computer. The iPhone app and the opt-in
-[SteamVR headset panel](headset-app.md) read the folder on the Frame. To use an
-extension in VR, copy its folder to
-`steamos@frame:~/.local/share/frame-control/extensions/`, then select
-**Extensions → Refresh extensions → Open** in the headset panel. The iframe,
-read-only bridge and asset rules are the same there.
-
-## Make an extension
-
-Create `extensions/your-id/manifest.json` and `index.html`. IDs use lowercase
-letters, digits and hyphens, start with a letter, and are at most 40 characters.
-The manifest ID must match the folder name:
-
-```json
-{
-  "id": "your-id",
-  "name": "Your feature",
-  "version": "1.0.0",
-  "apiVersion": 1,
-  "description": "What the panel does.",
-  "entry": "index.html"
-}
-```
-
-`apiVersion` selects the Frame Control bridge contract, independently of your
-extension's own `version`. This app supports integer `1`; a missing field means
-`1` for existing extensions. Unsupported versions appear as errors on Refresh,
-and their assets are not served. Declare it in new extensions so a future API
-change can fail clearly instead of running incompatible code. The runtime
-`capabilities` reply below reports the bridge version too.
-
-Put JavaScript in a separate `.js` file. Supported assets are HTML, JS, CSS,
-JSON, PNG, JPEG, GIF, WebP and SVG, all in the extension's top-level folder.
-Nested paths and symlinks are not served. No file may exceed 5 MiB. The panel
-uses an iframe with `sandbox="allow-scripts"`; its code has an opaque origin,
-cannot call Frame Control's HTTP API directly, and cannot navigate the app's
-top-level window. Content Security Policy restricts scripts, images, and
-`fetch` requests, but an extension can still navigate its own iframe to an
-external site. Treat third-party extensions as untrusted code and review them
-before installation.
-
-The version 1 bridge uses `postMessage`. Send a request to `parent` and match
-the numeric `id` in the reply. The [example JavaScript](../examples/extensions/headset-glance/main.js)
-shows a complete client:
-
-```js
-parent.postMessage({type: 'frame-control:request', id: 1, action: 'status'}, '*');
-// Reply: {type: 'frame-control:response', id: 1, value: {...}}
-```
-
-Supported actions:
-
-| Action | Value |
-| --- | --- |
-| `capabilities` | `{apiVersion: 1, actions: ['capabilities', 'status']}` |
-| `status` | `{connected, os: {version, build}, battery: {percent}, steamvr}` |
-
-`status` is the app's latest successful status snapshot. When that reading fails,
-`connected` is false and its fields are empty. No write actions are currently exposed. Future APIs
-should use explicit, narrow actions and keep the iframe isolated. A third-party
-extension is code you choose to run locally: inspect its files before copying
-them into the folder. A Decky plugin is a separate Steam client plugin and does
-not use this API.

-# Write a plugin for Frame
-
-There are two paths. Choose the one that matches your feature.
-
-## Frame Control extension
-
-Use a Frame Control extension for a panel, status view, or guide that does not
-need to change the headset. Put `extension.json` and `index.html` in one folder
-under `~/.local/share/frame-control/extensions`. The opt-in headset panel lists
-the folder and opens it in a sandboxed iframe. The version 1 bridge has only
-`capabilities` and read-only `status`. It cannot call Steam, change settings,
-or run privileged code. See [the extension API](extensions.md) and its example.
-
-## Decky plugin
-
-Use a Decky plugin only if you need Decky's backend or Gamepad UI integration.
-Build an official-format ZIP with one top-level folder, `plugin.json`, and a
-frontend bundle in `dist/index.js`. A Python `main.py` backend is optional.
-Test on ARM64. If you ship an ELF helper, build it for AArch64 (ELF machine
-183). Avoid root, `sudo`, Steam Deck TDP controls, fixed x86 binaries, and
-paths under `/etc`. Frame Control's managed loader is a normal user service;
-it blocks root plugins and x86 archives. Keep data under your plugin folder or
-the user's home directory, and provide a removal path.
-
-The current Frame SteamVR shell does not expose Decky's Steam Deck Quick Access
-Menu. A backend `Loaded` log only proves backend startup. Test any frontend
-page, setting, notification, route, and controller input while wearing a Frame
-before describing it as working in VR. Until a QAM bridge is verified, a Frame
-Control extension is the practical route for a visible read-only VR panel.
-
-To test safely, use a separate Frame Control managed Decky install, verify the
-ZIP digest from the official store, install one plugin at a time, and inspect
-`journalctl --user -u frame-control-decky.service`. Remove only your own
-plugin folder when you finish. See the current [compatibility table](decky-frame.md).

-# Frame Control in the headset
-
-**Experimental, Frame OS 0.5.6.** Tools → Frame Control in VR installs a local
-panel in SteamVR's dashboard. It is a way to reach Frame Control while wearing
-the headset, independent of Decky's Quick Access Menu. The panel starts only
-after you opt in; its server binds to `127.0.0.1` and it uses a normal user
-service. No `sudo`, root filesystem change, or Steam client patch is needed.
-
-The companion copies its bundled UI over the existing trusted SSH connection.
-On the Frame, `frame-control-headset.service` runs a loopback server and one
-Chromium app window on gamescope. The window receives a dedicated `STEAM_GAME`
-id, so SteamVR registers `valve.steam.desktopgame.2001947813` as a dashboard
-panel. **Show in SteamVR** requests that dashboard tab; the wearer can select
-it again from SteamVR's dashboard. Closing the panel stops its browser and
-server. The service is not enabled at boot.
-
-The page shows battery, free home storage and SteamVR status. It can request
-SteamVR's main Game Mode dashboard, list and force quit a running game after an
-unsaved-progress confirmation, save an OpenVR screenshot to
-`~/Pictures/FrameControl`, and record the SteamVR mirror to
-`~/Videos/FrameControl`. Recordings have a 20-minute limit and use a separate
-work folder from desktop Frame Control's recorder; they may have no audio if
-the monitor source is unavailable. Captures made in standby can be dark.
-
-The page also discovers extensions from
-`~/.local/share/frame-control/extensions` and opens them in sandboxed iframes.
-It offers the version 1 read-only `capabilities` and `status` bridge from
-[the extension guide](extensions.md). Installing an extension still means
-copying its folder to the Frame; the panel does not download third-party code.
-
-The panel also lists Decky plugins and can install, update, or remove compatible
-plugins from the official store when the opt-in managed loader is running.
-Each change asks for confirmation. The Frame VR shell does not show Decky's
-Steam Deck Quick Access Menu, so Decky plugin pages, settings, routes, and
-toasts are not available in this panel yet. The [compatibility table](decky-frame.md)
-separates backend loading from VR use. Authors can use the
-[Frame plugin and extension guide](frame-plugin-author.md).
-
-The per-run UI key is passed in the URL fragment, removed from the address bar after load,
-and sent in the `X-Frame-UI` header. The key is absent from the HTTP request
-line and server log. The usual host/origin and anti-framing checks still apply.
-
-## Real Frame test, 2026-10-25
-
-On Frame OS 0.5.6, build `20261022.6153909`, the opt-in install started the
-user service, served `/headset`, read live `/api/status` from the browser, and
-registered a mapped Chromium window with SteamVR under the dedicated overlay
-key. The server rejected a request with the wrong UI key. A read-only status
-probe reported the user service running and the overlay registered.
-
-The unworn headset was in standby (`activity_level` 3). SteamVR reported the
-new overlay as `not_visible` even after `ShowDashboard`. An OpenVR stereo
-screenshot was a uniform dark frame. The documented temporary wake attempt
-(`power.turnOffScreensTimeout` 5 → 3600, `--handlewakeup`, `ShowDashboard`)
-still left the overlay `not_visible`; the setting was restored to 5 and the
-dashboard hidden. The X window's `xwd` image was black too. These observations
-prove panel creation and page/API execution, **not wearer-visible pixels or
-laser/controller input**. A worn-headset check is still required before
-describing the panel as visually verified.
-
-The test then removed the managed service and app bundle. Its unit became
-inactive, port 47813 closed, the SteamVR overlay disappeared, and the Frame's
-battery was 100%. Steam and SteamVR were left running. The browser profile and
-extensions folder were deliberately kept.
-
-A second test on the same build installed the expanded panel with the
-`headset-glance` example extension. The headset's authenticated loopback API
-returned live status (99% battery), discovered and served the extension, and
-listed no running games. The Game Mode dashboard request succeeded; an invalid
-force-quit app ID was rejected with HTTP 400. Screenshot and recording actions
-saved a PNG and a 3.6 MB MP4 in the headset user's folders. The recording
-reported an audio source. The per-run UI key was absent from the server log.
-After another wake and dashboard request, SteamVR still reported the panel
-`not_visible`. No wearer-visible screenshot or controller interaction was
-obtained. The test removed its example extension and captured media, then
-uninstalled the service. The unit, port, bundle and overlay were absent after
-removal; Steam and SteamVR remained running.
-
-## Remove
-
-Use **Tools → Frame Control in VR → Remove**. If the companion is unavailable,
-run:
-
-```sh
-ssh frame 'systemctl --user stop frame-control-headset.service; rm -f ~/.config/systemd/user/frame-control-headset.service; systemctl --user daemon-reload; rm -rf ~/.local/share/frame-control/headset/bundle; rm -f ~/.local/share/frame-control/headset/receipt.json ~/.local/share/frame-control/headset/server.log'
-```
-
-That command removes only Frame Control's managed panel code. The Chromium
-profile remains in `~/.local/share/frame-control/headset/profile` so local
-extension data is not discarded. Inspect and delete that folder separately if
-you no longer want it. Third-party extensions are in
-`~/.local/share/frame-control/extensions` and are never removed by this tool.

-## SteamOS / Steam Machine PC host
-
-Use **Desktop Mode** on the SteamOS PC. Download the Linux x86_64 AppImage to
-your home folder. Make it executable and open it there; SteamOS has a
-read-only system root, so these steps do not use `apt` or change `/usr`:
-
-```sh
-chmod +x ~/Downloads/Frame-Control-linux-x86_64.AppImage
-~/Downloads/Frame-Control-linux-x86_64.AppImage
-```
-
-If AppImage mounting reports a FUSE error, try
-`APPIMAGE_EXTRACT_AND_RUN=1 ~/Downloads/Frame-Control-linux-x86_64.AppImage`.
-This extracts to writable temporary space and needs enough free disk space.
-Set up the Frame's SSH connection in Frame Control, then use **Start OBS
-source** before you add or activate OBS's Media Source. Install OBS as the
-`com.obsproject.Studio` Flatpak through Discover or your normal user Flatpak
-setup. In that OBS Media Source, clear **Local File**, set **Input** to
-`udp://127.0.0.1:15099`, and set **Input Format** to `mpegts`. Make a short
-recording and check both picture and sound before a stream. Use **Stop OBS
-source** in Frame Control when done.
-
-The OBS Flatpak's published manifest includes `--share=network`, which is
-needed for its local UDP receiver. Check your installed permissions with
-`flatpak info --show-permissions com.obsproject.Studio` if OBS receives no
-packets. Frame Control's helper sends to loopback on this PC; it does not
-require an open LAN port or an OBS plugin. The PC does not need a system
-`ffmpeg` package for the helper; encoding runs on the Frame.
-
-**Test limit:** The v0.4.27 AppImage launched on an Ubuntu 24.04 x86_64 host
-under Xvfb. Its helper sent H.264 and AAC from a real Frame to a local UDP
-receiver on that host. No SteamOS 3.9.5 PC, Steam Machine, Flatpak OBS runtime,
-read-only-root host, or physical display was available for this check. The
-SteamOS steps and Flatpak receiver therefore remain **untested on SteamOS**.
-See the [test record](evidence/obs-steamos-host-2026-10-25.md).

-## Known issue: game audio in OBS
-
-A Frame owner [reported](https://x.com/AzizahStellazio/status/2114147449468293171)
-that OBS **Game Capture / Application Audio Capture** can lose game audio when
-the headset turns on. OBS support attributed this to Valve/SteamVR. Frame
-Control cannot change that game-audio routing. If it happens, use Frame
-Control's **Start OBS source** and OBS **Media Source** steps above to capture
-the headset view and its output audio. You can also try OBS **Desktop Audio
-Capture** for the computer's output, then check its meter and a short test
-recording before you stream. Do not leave two active sources for the same audio
-unless you want duplicate sound.
-
-The real Frame/OBS check above proved that a synthetic tone from the Frame's
-output reached the Media Source recording. It did **not** use a running game,
-listen to the audio, reproduce the reported Game Capture failure, or measure
-audio/video sync. Real game audio while the headset is awake remains unverified.
-
-## Check sync and recover a blank source
-
-Make a short recording of a visible click, clap or other simultaneous marker
-and sound before streaming. Open **Advanced Audio Properties** in OBS. If audio
-arrives early, hide/deactivate this Media Source, add a positive **Sync Offset
-(ms)** in Advanced Audio Properties, then show/reactivate it, record again,
-and check the result. Changing the offset during playback did not correct
-the tested OBS 30 source. Setting it before activation did: a +480 ms offset
-reduced a 480 ms lead to 0 ms within the test resolution in three pulses. The 2026-10-25 Linux software-rendering test measured
-about 0.4 seconds of audio lead with default OBS settings. This is a measured
-setup result, not a universal offset. Do not apply it blindly to another host.
-
-Start Frame Control's source before adding or activating the OBS Media Source.
-After Stop/Start or a connection failure, hide and show the Media Source, or
-reopen its properties and click OK, to reopen its UDP receiver. Keep only one
-receiver on a port. If another application owns 15099, stop the relay, choose
-another port in **OBS setup**, and change the OBS Input to match. Sending UDP
-packets does not confirm that OBS has received or decoded them.
-
-A stalled stream ends with an error. Wake or reconnect the Frame and press

-# Plugin and modding research
-
-Checked **2026-10-25**. Decision: keep the experimental, reversible Decky manager
-and ship Frame Control's own sandboxed panel API as the supported way to add
-local features. Both implementations already landed in the replacement job
-while the original job was unavailable. This report consolidates their evidence
-and the original research questions; it does not claim another loader was built.
-
-## Can Decky run on Frame?
-
-**Its ARM64 backend and Steam shared-context injection work on the tested build.
-A usable Decky menu inside VR remains unverified.** Do not equate an active
-service or a JavaScript plugin registration with a working headset interface.
-
-| Requirement | Evidence | Consequence |
-| --- | --- | --- |
-| ARM64 Linux binary | Upstream [3.3.0](https://github.com/SteamDeckHomebrew/decky-loader/releases/tag/v3.3.0) has `PluginLoader-arm64`; Frame reports `aarch64` | ARM is not itself a blocker. Individual plugins may still ship x86 binaries or assume Deck hardware. |
-| Steam Gamepad UI and CEF | Loopback `127.0.0.1:8080/json/list` exposes `SharedJSContext` plus distinct SteamVR pages | The shared context exists; the VR shell is a separate integration target. |
-| CEF enable marker | `~/.steam/steam/.cef-enable-remote-debugging` is absent, but CEF already answers | No marker or Steam launch flag change is needed on this build. |
-| User service manager | `systemctl --user show-environment` succeeds | A per-user service works without installing an upstream root service. The manager is degraded by a stale failed Decky unit, although its unit file is gone. |
-| Filesystem | `/` currently mounts `rw` on Btrfs, `/home` mounts `rw` | This is an observation of this device, not a stock-image guarantee. Do not disable SteamOS read-only protection or install packages in `/usr`. |
-| Homebrew folder | `~/homebrew` is absent | It is an installer convention, not a preinstalled SteamOS plugin API. Frame Control uses a separate managed directory. |
-| Visible menu | Earlier tests registered Decky's tab only in shared JavaScript; SteamVR had no Decky overlay; headset was in standby | QAM visibility, controller input and a real plugin's visible result remain unverified. |
-
-The fresh [read-only probe](evidence/plugins-2026-10-25.json) records SteamOS
-`0.5.6`, `VARIANT_ID=vr`, build `20261022.6153909`. It confirms CEF, architecture,
-mounts, user-service availability, and absence of a running managed or upstream
-Decky installation. This retry did not install anything or restart Steam.
-
-The replacement job's initial [test record](decky-frame.md) reports:
-
- Decky 3.3.0 started as the normal `steamos` user and injected into
-  `SharedJSContext`.
- Install → status → update → status → remove → status succeeded on the Frame.
-  Removal left the unit, binary and port 1337 absent, while preserving user data.
- ProtonDB Badges 1.1.0 loaded as a passive plugin and appeared in Decky's
-  shared-context registry. Its badge or menu was not seen inside VR.
- Injected frontend code can outlive backend removal until Steam's web helper
-  restarts. An earlier helper-restart test cleared the globals; this retry did
-  not repeat it.
-
-These are prior documented results, separate from the fresh read-only probe.
-The coordinator then ran a separate, locked
-[official-store compatibility audit](decky-frame.md#official-store-plugin-audit-2026-10-25)
-on the same Frame OS build. Seven plugins logged backend loads. A managed
-ProtonDB Badges 1.3.4 store install, update and remove also succeeded. The
-headset stayed unworn, so these results still do not establish VR UI use.
-
-## Installer and update choice
-
-The upstream [installer at e42a3c8](https://github.com/SteamDeckHomebrew/decky-installer/blob/e42a3c828de90673959b4de26cf5c5d2c7830554/cli/install_release.sh)
-escalates through sudo, creates `~/homebrew/plugins` and `services`, writes the
-CEF marker and a system unit under `/etc/systemd/system`, and starts Decky as
-root. Its architecture switch supports `aarch64|arm64`. Running this installer
-is unnecessary for a compatibility check and grants more access than a panel
-extension needs.
-
-Frame Control's [manager](../ui/frame_decky.py) instead downloads the official
-ARM64 asset, checks GitHub's published SHA-256 and the ELF machine, and writes
-only under `~/.local/share/frame-control/decky` and `~/.config/systemd/user`.
-It refuses an upstream system-service installation, requires active CEF before
-install/update, and restores the previous binary, receipt and unit if applying
-an update fails. Existing tests exercise that rollback with a failed service
-start. These checks do not prove every possible OS or Steam update is safe.
-
-The binary is downloaded on demand, not bundled. Plugin discovery lists the
-managed directory and upstream `~/homebrew/plugins`. The later
-[store manager](../ui/frame_decky_store.py) exposes official entries in the PC
-app and opt-in headset panel. It verifies archive digests, blocks root and
-non-ARM64 binaries, and changes only its own plugin folders. That is file and
-backend support, not a working VR plugin page. Decky plugins can execute
-backend code and are not isolated by Frame Control's HTML extension sandbox.
-
-Home-directory state is expected to survive SteamOS image updates, based on
-SteamOS's layout; **an actual OS update and reboot persistence test has not been
-performed**. Steam frontend changes, CEF availability, libc requirements and
-plugin hardware assumptions can still break Decky. On failure, remove the user
-service using [the documented removal command](decky-frame.md#opt-in-and-remove);
-its removal path does not require a working CEF target. Test the sequence again
-on each supported OS build before expanding support claims.
-
-## Other paths
-
-| Path | What it enables | Current limits and choice |
-| --- | --- | --- |
-| Decky plugins | Steam frontend hooks, optional Python backends | Seven official-store plugins logged backend loads on ARM64. Store install/update/remove worked for ProtonDB Badges. VR pages and controller input remain unverified. Keep experimental. |
-| [CSS Loader](https://github.com/suchmememanyskill/SDH-CssLoader) / [DeckThemes](https://docs.deckthemes.com/) | Stylesheets applied to Steam UI | CSS Loader 2.1.3 backend loaded on Frame. No theme was applied or visually tested. Deck themes do not establish compatibility with Frame's separate VR shell. |
-| User home / SteamOS homebrew | User services, user Flatpaks, files and helpers | Use owned folders and explicit uninstall. A folder named `homebrew` supplies no discovery or security boundary by itself. No rootfs changes needed for the chosen path. |
-| Android / Lepton | Sideloaded apps, game-specific content and per-app settings | Frame Control already manages APKs and ADB. Lepton runs Android containers, not Steam's CEF UI; an Android mod does not add a Steam dashboard tab. No new Android mod was tested here. See [APKs](apks.md), [VR APKs](vr-apks.md), and [game mods](mods.md). |
-| Frame Control extensions | Third-party HTML/CSS/JS panels with a small read-only bridge | Shipped in [#194](https://github.com/saphid/frame-control/pull/194), with a manifest, local folder, sandbox, example and [author guide](extensions.md). No Python imports, arbitrary SSH commands or write actions are exposed. |
-| Frame Control's headset panel | Runs the local tools and extensions as a SteamVR panel | Shipped in [#198](https://github.com/saphid/frame-control/pull/198), expanded in [#201](https://github.com/saphid/frame-control/pull/201). Page/API execution and uninstall were tested; wearer-visible pixels and controller interaction remain unverified. See [test record](headset-app.md). |
-
-The extension iframe has `sandbox="allow-scripts"`, an opaque origin, restrictive
-CSP and a `postMessage` bridge accepting only `capabilities` and a reduced
-`status` snapshot from the active frame. It is useful for local dashboards and
-small tools today. It cannot replace the full Decky API. Third-party code still
-needs review: an iframe may navigate itself externally, and local installation
-does not establish publisher trust.
-
-Extensions are loaded only when opened and are removed by closing their panel
-and deleting their own directory. They modify no SteamOS files. The
-[compatibility follow-up](https://github.com/saphid/frame-control/pull/209) adds
-manifest `apiVersion` validation during discovery and asset serving, with
-existing manifests defaulting to version 1. It rejects incompatible panels
-even when requested through a direct asset URL.
-
-## Licences: separate download versus bundling
-
-Decky's [licence](https://github.com/SteamDeckHomebrew/decky-loader/blob/00cd202872b85868071b041c8f1b34e734147195/LICENSE)
-is GPL version 2. Frame Control is MIT-licensed. The integration contains its
-own service-management code and downloads the upstream executable as a separate
-program. It does not incorporate Decky source or ship its binary in Frame
-Control installers. Keep the upstream licence/source links visible to users
-who opt in; installing a separate GPL program does not by itself relicense
-Frame Control's independent code.
-
-If a future release bundles or mirrors Decky binaries, the distributor must
-preserve copyright/licence notices and satisfy GPLv2's corresponding-source
-requirements for the exact binary, including modifications and build scripts
-as applicable. A link to an evolving default branch is not a substitute for
-meeting those distribution obligations. Mere aggregation and deriving or
-linking a combined work are different questions; reassess the boundary if
-Decky code is incorporated. Each plugin, theme and bundled dependency has its
-own licence and assets to check independently. The existing
-[third-party notices](../THIRD_PARTY_NOTICES.md) describe software already
-distributed with Frame Control.
-
-## Next checks
-
-1. On a worn Frame, establish an accessible Decky menu or implement an adapter
-   for the VR shell. Verify a plugin's visible result and controller navigation
-   before describing store-installed plugins as usable inside VR.
-2. Verify the Frame Control panel and example extension visually, including
-   opening, refreshing and closing with the controllers.
-3. Test a normal Steam restart, reboot and SteamOS update with a disposable
-   managed install; confirm removal still works with CEF unavailable. Retain
-   the experimental label until those checks pass.
-
-The release coordinator owns those ongoing headset-integration checks. This
-retry leaves the headset untouched and hands over the research and compatibility
-follow-up instead of running concurrent loader experiments.

-Download only from this GitHub release. Check your installer against [SHA256SUMS](https://github.com/saphid/frame-control/releases/download/{tag}/SHA256SUMS). A matching hash proves that your file matches the file in this release. It does not prove that any program is free of malware.
-
- Windows PowerShell: `Get-FileHash .\Frame-Control-Setup-x64.exe -Algorithm SHA256`
- macOS Terminal: `shasum -a 256 Frame-Control-mac-arm64.dmg`
- Linux terminal: `sha256sum Frame-Control-linux-x86_64.AppImage`
-
-Find the same filename in `SHA256SUMS` and compare all 64 hex characters. [Read the source](https://github.com/saphid/frame-control) and [see the build workflow](https://github.com/saphid/frame-control/blob/main/.github/workflows/release.yml). The Windows installer is **not code-signed**; SmartScreen may warn. The macOS app has only an **ad hoc signature**, not an Apple Developer ID signature; the DMG is **unsigned and not notarized**. Gatekeeper may warn or block it. Follow the opening steps in the README only if you trust this download.

-<p>The doctor checks Frame Control's SSH route only. If the SteamVR stream stops on USB, Wi-Fi and the Wireless Adapter, the problem may be on the PC. On a Windows or Linux PC, first save your work and close the VR game. Exit SteamVR from Steam on the PC, then start SteamVR again. Frame Control reconnecting to <code>frame.local</code> will not restart PC SteamVR. This is a manual test, not a fix for the cause of repeated drops. Frame Control does not restart PC SteamVR automatically because it cannot safely know which game and session it would stop.</p></section>
