+# Changelog
+
+## 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).
+
+- Keep Steam clip exports separate for each headset, Steam account and nested
+  recording session. Manual export and automatic copying use the same folders;
+  existing flat exports stay untouched and do not mark unrelated clips saved.
+  [Recording guide](docs/recording.md#steam-clips).
+
+- 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.
+  No adapter setting changes or report uploads are made.
+
+- Add recovery steps to the Windows Wireless Adapter doctor for streams that
+  drop as they start and dongles that will not reconnect. Compare exact PnP IDs
+  and test one connection condition at a time. In-app disable/re-enable remains
+  deferred until an active Steam adapter instance can be identified safely.
+  [Guide and limits](docs/windows-wireless-doctor.md).
+
+- Add an explicit host window-switch button to whole-display panels: Alt-Tab
+  on Windows and Command-Tab on macOS. Single-window panels keep their own
+  source, so the button is hidden there.
+
+- Enable the in-app OBS source Start/Stop control on Windows. A control pipe
+  lets the Python relay close its SSH child on Stop, app quit or parent exit;
+  add a short [Discord guide](docs/streaming-to-discord.md).
+
+- Add a read-only wired connection doctor for a PC using the Frame's observed
+  USB-C network: show the local route, SSH port and pinned-key login result
+  without changing IP, host keys or headset settings.
+  [Usage and limits](docs/wired-connection.md).
+
+- Start the Android app catalogue without waiting for the headset's installed-app
+  list. Browsing remains available if that status request is slow or fails;
+  installation still waits for a confirmed list to avoid duplicate installs.
+
+- Verify the packaged OBS Start and Stop control with a real Frame, and record
+  37.600 seconds of headset mirror video and non-silent output audio in OBS.
+  Listening, sync and active passthrough remain unverified.
+  [Test record](docs/evidence/obs-media-source-real-2026-10-25.md).
+
+- Bundle the OBS source helper in Linux and macOS installers and add a
+  **Capture & Live** Start/Stop control. The app selects the active Frame and
+  closes its SSH stream on a headset switch or app exit. A real Frame stream
+  reached OBS with video and non-silent audio; listening and sync remain
+  unverified. [Setup and limits](docs/obs-headset-source.md).
+
+- Add a source-checkout helper that sends the Frame's SteamVR mirror and
+  default-output audio to a local OBS Media Source. A real Frame supplied a
+  4.021-second H.264/AAC stream to a Linux receiver; OBS playback and sync
+  remain unverified. [Setup and limits](docs/obs-headset-source.md).
+
+- Link emulator setup guidance from Store → Emulators. Existing Steam library
+  shortcuts and artwork cover Android apps and sideloaded titles; Android ROM
+  transfer still needs a verified per-instance workflow.
+  [Guide](docs/emulators.md).
+
+- Record the current Frame OS mirror and charge-limit checks. Active
+  passthrough in the mirror is still unknown; this build has no supported
+  user-writable 80% charge-limit control.
+  [Headset evidence](docs/evidence/round3-headset-2026-10-25.md).
+
+- Add Windows Tools → Wireless Adapter doctor: an explicit read-only PC snapshot
+  of distinct Wi-Fi Direct PnP instances, presence/link state, PC Wi-Fi and
+  reported channels/bands, with possible 2.4 GHz overlap guidance. Unknowns stay
+  visible; no adapter disable action is offered because an unused instance
+  cannot be identified reliably. No headset access or settings changes.
+  [Sources, verification and limits](docs/windows-wireless-doctor.md).
+
+- Add a Linux PC Wireless Adapter doctor in Settings and Devices, with a source
+  CLI and local JSON report. Select observed hardware without assuming Valve
+  IDs; inspect USB/interface presence, driver/module binding, udev/permissions,
+  rfkill, channel/band and network manager evidence. Missing evidence stays
+  unknown; all checks are read-only and never contact the Frame.
+  [Usage and verification limits](docs/linux-wireless-adapter-doctor.md).
+
+- Add Linux Tools → Steam desktop sharing: request `steam -pipewire` only after
+  checking Steam is not running, or open KDE Application Permissions with
+  instructions to revoke a verified Steam screen-sharing session manually. No
+  automatic permission reset, Steam restart, or headset access. Frame Control
+  Linux capture remains disabled; live portal behavior is unverified.
+  [Usage and limits](docs/steam-pipewire.md).
+
+- Use gamescope's input for the keyboard and trackpad, following the focused
+  headset panel without installing an input service. Start KDE Connect only for
+  accents and emoji, keeping queued text ordered and cancelling it on headset
+  switches. Retain intended-headset checks before starting either control and
+  prevent Unicode helper startup from deadlocking with a headset switch.
+- Keep accepted keyboard text when the Unicode queue is full: reject new batches
+  before sending their clicks or keys, and count in-flight text toward the limit.
+  Retain unsent text after helper failures/timeouts, report the error and resume
+  it with Try again. Clean up failed workers without touching a new headset's queue.
+  [Current verification and device limits](docs/evidence/pad-gamescope-2026-10-24.md).
+
+- Keep media playback running when SteamVR refuses the optional theatre dark
+  surround, including a retry after standby. Log the refusal and play without
+  the surround. Overlay teardown attempts every owned handle and always calls
+  OpenVR shutdown even if a handle fails to close.
+
+- Check the desktop server's single-instance lock before starting background
+  downloads, so a second server exits cleanly with the existing "already
+  running" message.
+
+- Recheck saved spatial layouts on SteamOS 0.5.6 / SteamVR 2.18.2 (issue #31).
+  Read-only probes expose some panel geometry, but safe restoration of
+  Steam/gamescope docking and positions remains unverified. Record exact API
+  results and a reproducible probe; saved layouts remain unavailable.
+
+- Record packaged v0.4.17 Desktop Capture succeeding on a mapped nested KDE
+  compositor on a real Frame with SteamOS 0.5.6. Headset overlay visibility was
+  not established; this is evidence, not a new fix or resolution of issue #73.
+
+- Correct the Return to Game Mode help text: Frame Control selects the switch
+  supported by the headset's SteamOS build, including `steamosctl` on current
+  Frames. The button's behavior is unchanged.
+
+- Distinguish an unreadable gamescope panel list from a confirmed empty list in
+  Desktop Capture and Control (issue #73). Failed discovery now asks users to
+  check SteamVR and report the exact message and SteamOS version, rather than
+  claiming no panel is open. This does not establish a new capture fix.
+
+- Add an opt-in desktop low-battery alert without starting a family session.
+  Existing status reads confirm low charge and drain; recovery hysteresis and a
+  ten-minute cooldown limit repeat alerts. Off on page open/headset switch;
+  pauses with hidden-page status refreshes. No extra polling or headset changes.
+
+- Clarify first-time desktop downloads, installation and opening on the website
+  and README, including CPU choices, unsigned-app warnings, pairing fallback
+  and the source-only iOS build. Keep section navigation available on mobile.
+
+- Treat headset aliases and other CSV metadata as plain text in power and heat
+  exports, so spreadsheet formula prefixes cannot run when a report is opened.
+
+- Add desktop Tools → Power & heat report: bounded read-only one/five-minute
+  observations with progress, stop and HTML/JSON/CSV downloads. Received samples
+  survive stop, disconnect and headset switch, labeled incomplete and tied to the
+  original headset. Shared sampler/report modules ship with the app; no power or
+  thermal controls are added. Download before replacing a report or quitting.
+
+- Fix Return to Game Mode misidentifying full Plasma Desktop Mode when its VR
+  overlay also runs gamescope (issue #142). Session targets now determine the
+  mode; conflicting or incomplete evidence stays unknown. Use SteamOS's
+  `steamosctl` switch when available, with older selector commands retained.
+
+- Export read-only power and heat observations to an offline accessible HTML
+  report with JSON/CSV downloads. `--html FILE` limits sessions to ten minutes;
+  Ctrl+C saves received samples with an explicit incomplete state. Units,
+  unknown counts and sources remain visible; no headset controls are added.
+
+- Add a guarded `frame-doctor.sh --plan` with read-only, evidence-specific next
+  steps and explicit local baseline reports for before/after diagnostics (issue
+  #34). Restart risk blocks plans/comparisons; no automatic repairs, password
+  changes or headset security changes are performed.
+
+- Recover a tagged release upload when GitHub temporarily displays its draft
+  as `untagged-…` after an edit, without creating a duplicate draft or
+  silently retrying unrelated upload failures.
+
+- Import standalone APK/OBB backups from XAPK/APKS/APKM archives through the
+  existing preview and game-data setup flow. Unsafe archives, split sets and
+  Android/data restores are refused with guidance. This does not establish RE4
+  compatibility or diagnose its reported failure (issue #102).
+
+- Add `scripts/frame-power-sample.sh`, a bounded read-only SSH sampler for
+  battery, CPU, named temperatures, fan and available power rails (issue #52).
+  JSON samples/summaries and CSV exports retain explicit unavailable states;
+  active smoke-test locks stop measurement. No power settings are changed.
+
+- Show saved Android compatibility reports on store search cards and app details.
+  Reports refresh in the background, so a stalled database or credential lookup
+  cannot delay search. Warnings allow installation; build compatibility blockers
+  still apply. Public copies use this computer's reports, not private shared ratings.
+
+- Fix two cases where optional diagnostic logs could retain part of a headset
+  display name or an SSH host name, while preserving existing privacy redaction
+  (issue #81).
+
+- Keep the full host-key recovery explanation readable in Devices, including
+  long addresses, and remove doubled punctuation from the connection tooltip
+  (issue #87). Refresh stays within the header and switching headsets selects
+  the new headset's details.
+
+- Fix experimental PC screen capture on Windows builds whose streaming libraries
+  lack Windows Graphics Capture. Whole screens use Desktop Duplication; individual
+  windows are hidden with an explanation instead of failing when shown. A Windows
+  VM streamed a real desktop to the Frame; physical input remains unverified.
+
+- Add read-only battery health in Tools: charging state, temperature, cycle count,
+  and available capacity with explicit unknown states. The parser was checked
+  on a real Frame; the connected desktop UI was tested with synthetic readings.
+
+- Add Tools → Game storage: read-only headset filesystem capacity and Steam
+  library/game install-size breakdown, with unknown sizes, partial inventories
+  and permission/missing-drive states. Includes instructions for Steam's own
+  Move UI; Frame Control does not move or delete game files. The read-only
+  parser was checked on a real Frame; the connected UI and game moves were not.
+
+- Add `scripts/frame-doctor.sh` for read-only setup and pairing diagnostics,
+  with verified SSH identity, private summaries and actionable next steps
+  (issue #34). Connection steps links to the diagnostic guide. Repairs remain
+  manual; restart-loop evidence stops deeper diagnostics. The real Frame
+  verified the SSH connection and safety stop; deeper checks were skipped.
+- Fixed headset smoke cleanup reporting success while a smoke-title process
+  could remain running after its files were removed. Cleanup now stops and
+  rechecks processes tied to exact reserved test-title paths, uses PID handles
+  for safe TERM/KILL escalation, and records stopped PIDs. Unrelated titles and
+  shared Wine services are left alone. Verified with local Linux process
+  regressions and a 13/13 real Frame smoke run that stopped five test-owned
+  Proton process PIDs before removing the Windows test title.
+
+- Keep failed automatic screenshot and clip copies visible after three attempts.
+  **Resume** and **Copy everything now** allow another try without restarting;
+  headset switches cannot use another headset's list or saved-file history.

+## Open the app
+
+**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. A source checkout does not offer this setting.
+
+- **macOS:** open the `.dmg`, drag **Frame Control** to **Applications**, then
+  open it from Applications. For the Gatekeeper warning, use the macOS steps
+  above. Allow local network access and control of Terminal when prompted.
+- **Windows:** run the installer, then open **Frame Control** from Start. For
+  the portable download, extract the entire `.zip` first and run
+  `Frame Control.exe` inside it. See the SmartScreen note above.
+- **Linux:** install the `.deb` with your package installer and launch
+  **Frame Control** from your applications menu; or make the AppImage executable
+  and run it as described above. Install the OpenSSH client if `ssh` is missing.
+
 ## Set up the headset
 
-You type one password on the headset, once. Everything else happens on your
-computer.
+Keep the Frame awake and connect it and your computer to the same trusted local
+network. Guest Wi-Fi/client isolation can prevent discovery and connections.
 
 1. **On the Frame:** Steam Settings → System → **Enable Developer Mode**, then
-   in the Developer section, **Set User Password**. Pick something short:
-   you'll type it once more on your computer and then never again.
-2. **On your computer:** open Frame Control. It offers to **Set Up
-   Connection**, which finds the headset, creates an SSH key, and asks for that
-   password once in a terminal window. If it can't find the Frame, type the
-   IP address from the Frame's Quick Settings.
+   Developer → **Set User Password**. Choose a password that isn't easy to guess:
+   it also protects `sudo` and remote desktop, even after SSH keys are set up.
+2. **On your computer:** open Frame Control and choose **Set Up Connection…**.
+   If you dismissed the first-run prompt, use **Frame → Set Up Connection…**.
+   Setup opens a terminal and tries to find the headset. If it can't, use its IP
+   address from Quick Settings or Steam Settings → Internet. Windows/Linux setup
+   prompts for it; macOS exits instead. On macOS, return to the app →
+   **Devices & connection → + Add a headset…**, set SSH alias to `frame` for
+   the default headset, fill in **Address**, then choose **Set Up…**.
+3. **Pair or enter the password:** setup first tries Valve's devkit pairing.
+   Open Steam Settings → Developer → **Pair new host** in the headset and approve
+   only the request you just started. The service and pairing-mode step are
+   verified on a Frame; approval and key installation through that flow remain
+   unverified. If pairing fails or times out, setup falls back to asking for the
+   Developer Mode password in the computer's terminal. Password typing may show
+   no characters; press Enter when done. See [SSH details](docs/ssh.md#password-free-pairing-steamos-devkit-service).
+4. After setup succeeds, return to Frame Control. It uses SSH keys for later
+   connections whenever the Frame is awake and reachable. If it stays offline,
+   check Developer Mode, the address and network isolation, then run setup again.
+   For connections away from home, see [Tailscale](docs/tailscale.md).
 
-   Before asking for the password it tries Valve's SteamOS devkit pairing: in
-   the headset, open Steam Settings → Developer → **Pair new host** and approve
-   the request, and no password is needed. (The service and the pairing-mode
-   step are verified on a Frame; the approval itself isn't yet. See
-   [SSH](docs/ssh.md#password-free-pairing-steamos-devkit-service).)
-3. That's it. The app now reaches the headset whenever it's awake and on the
-   same network. For anywhere else, see [Tailscale](docs/tailscale.md).
+**Does Frame Control lower streaming lag?** No. Frame Control manages the Frame
+over SSH. SteamVR or Steam Link carries the game stream. Frame Control does not
+carry that stream, lower ping, or need the Wireless Adapter. It can connect over
+Wi-Fi, the Wireless Adapter, or USB when your computer has an SSH route to the
+Frame. The wired doctor checks only that SSH route. A data-capable USB-A-to-C
+cable has not been tested for the Frame's USB network. See the
+[connection FAQ and Japanese quick start](docs/connection-faq.md).

+
+You can instead select **one `.xapk`, `.apks`, or `.apkm` archive** containing
+one base APK, optional supported splits and matching OBBs. These extensions describe
+containers, not a guarantee that their contents are supported. OBBs may be
+at the archive root, under `<package>/`, or under `Android/obb/<package>/`;
+one enclosing backup folder is allowed. Known manifest/icon/signature
+sidecars are ignored; the APK manifest determines the package. Unknown files,
+unsafe paths, links, encrypted entries, duplicate paths (including case
+collisions), more than 4,096 entries, or more than 16 GiB unpacked are refused.
+Staging also keeps 64 MiB of free disk space. Payloads still have the regular
+100-file/99-OBB limit. Ordinary `.zip` files keep the PC-title import route;
+extract an Android ZIP yourself and select its APK/OBBs.
+
+The importer previews the app and files before **Import game & data**.
+Confirming authorizes installing the app, starting it to prepare Android,
+checking the running package/version, copying OBBs through the existing
+verified data helper, and closing the game. Open it from Steam afterwards.
+If setup fails, read the error and retry the same backup; do not uninstall
+first, since that deletes saves. An app that cannot start may also prevent
+data setup. Uploaded and extracted staging is removed on cancellation,
+inspection failure, or job completion/failure; abandoned imports expire
+through the existing one-hour staging lifecycle. Original local files stay intact.
+
+**Limits:** this backup importer requires exactly one base APK. For split sets,
+each split must identify the same package and version, and pass the existing
+[Quest split merger](quest-import.md#split-apks). It refuses resource, code and
+feature splits and does not choose among device variants. Merging re-signs the
+APK, which can affect licences. It does not restore `Android/data`, private app
+data, saves or entitlements. These split imports have local fixture and merger
+tests, but no real split game has been installed with this backup route on the
+Frame.
+
+For issue #102, the RE4 report only establishes that an APK attempt failed.
+Missing OBBs are a hypothesis; the edition/build, exact files, failing step,

+and SteamOS versions, and sanitized server/crash errors before diagnosing it.
+`python3 ui/frame_android.py info /path/to/game.apk` inspects the APK locally.

+# Battery and health monitoring

+Open **Control Center → Battery & thermal health**, or expand **System
+information**, to read the Frame's charge, charging state, signed battery
+power, battery temperature and driver-reported health. Optional readings show
+charge cycles, full charge capacity, design capacity and full / design capacity.
+The existing battery chip also shows charging state and temperature.
+
+These are read-only readings from the Linux host's `/sys/class/power_supply`,
+not Android's container battery view. The probe prefers the documented Frame
+fuel gauge, `max1720x_bat_7-36`, over other battery nodes, excludes peripheral
+(`scope=Device`) and absent batteries, and otherwise uses a deterministic
+battery fallback. The UI shows the selected source path.
+
+| Reading | Linux attribute | Interpretation |
+|---|---|---|
+| Charge | `capacity` | Integer 0–100 percent; zero is a real reading |
+| Charging state | `status` | Charging, Full, Discharging or Not charging; missing/unknown states stay unavailable |
+| Battery power | `voltage_now × current_now` | Microvolts and microamps converted to signed watts; positive means charging on the Frame |
+| Temperature | `temp` | Tenths of a degree Celsius, including valid negative readings |
+| Battery health | `health` | Driver status such as Good or Overheat; not a wear percentage |
+| Charge cycles | `cycle_count` | Driver-reported count, including zero |
+| Full/design capacity | `charge_full`, `charge_full_design` | Microamp-hours converted to mAh |
+| Full / design capacity | Ratio of those two capacities | Fuel-gauge estimate; not a diagnosis or a guaranteed runtime |
+| Time estimate | `time_to_full_now`, `time_to_empty_now` | Seconds; displayed only for the corresponding charging/discharging state |
+
+Unavailable means the field is absent, unreadable or invalid. One missing
+sensor does not hide the others. Zero design capacity cannot produce a ratio. Time estimates outside 1 second
+to 7 days and battery temperatures outside −273.15 to 200 °C are rejected
+as invalid readings; these bounds are not thermal warning thresholds.
+The ratio may exceed 100% because full capacity is a gauge estimate, so the app
+does not clamp it or invent a wear warning. The app does not estimate health
+from charge percentage or assign temperature thresholds. Existing thermal
+alerts use the kernel's own hot/critical trip points.
+
+A connected charger does not necessarily mean charging: the Frame can still
+drain under load or sit idle near full charge. A 100% capacity reading alone
+does not prove the driver reports Full. Missing status is explicitly unknown;
+near-zero measured battery power with a charger is shown as not charging.
+Failed, stale or disconnected status samples clear Control Center readings.
+
+**No charge controls are provided.** Frame's SteamOS charge-limit backend is
+unsupported; see [charge-limit research](charge-limit.md). Monitoring never
+writes to power supplies, pauses charging, changes current or sets a limit.

+malformed/missing values, permission failures, source selection and partial
+sensor support. `tests/control_center.cjs` exercises charging states, optional

+# 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).
+
+### Which of these plugins can open a Framey panel?
+
+The separate Framey panel accepts a Frame Control store install only when its
+`plugin.json` declares `api_version: 2` and it has `dist/index.js`. A backend
+load does not bypass this frontend check. We downloaded the 11 versions above
+again on 25 October 2026 and matched every ZIP's SHA-256 to the official store
+catalogue. All 11 had a frontend bundle, but their manifests differed:
+
+| Manifest in the checked archive | Plugins | Framey panel result |
+| --- | --- | --- |
+| API v2 | ProtonDB Badges 1.3.4 | Eligible; settings rendered in local Chromium. No worn VR check. |
+| API v1 | Bluetooth 3.1.1, HLTB for Deck 2.0.12, SteamGridDB 1.8.1, Storage Cleaner 1.4.0, Wine Cellar 0.2.1, MagicPods 2.0.21 | Framey refuses these frontends. Wine Cellar and MagicPods also fail the ARM64 archive check. |
+| No `api_version` field | CSS Loader 2.1.3, Animation Changer 1.3.2, Audio Loader 1.6.1, PowerTools 2.0.3 | Framey refuses these frontends. Audio Loader and PowerTools also request root. |
+
+The [archive audit record](evidence/framey-official-archive-audit-2026-10-25.json)
+has each store ID, exact version, SHA-256, manifest field, and bundle check.
+This is a static PC inspection. It does not show that any plugin is visible or
+usable in the headset. The earlier real Frame backend checks in the table above
+remain the only device evidence for these versions. A new store version needs a
+new check because its manifest and binaries can change.
+
+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. Its separate Framey iframe now hosts
+compatible API v2 plugin pages, settings, local routes, and panel toasts.
+Steam route patches and system notifications remain unavailable. The panel
+still needs a worn-headset visual and controller check. See the
+[current compatibility table](frame-plugin-author.md#framey-api-v2-compatibility).
+
+## 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 experimental [Framey panel host](framey-loader.md) can render compatible
+plugin settings inside Frame Control's separate SteamVR dashboard panel.
+The real headset still needs a worn-user visibility and controller check.
+
+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.
+The desktop app and headset panel share one lock for managed Decky changes.
+If another change is in progress, wait for it to finish and try again.
+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.

+# Emulators and your own games
+
+Frame Control's **Store → Emulators** lists Android emulators from its open
+app sources. Pick an app, read its compatibility result, and install it. An
+installed Android app gets its own Steam library shortcut and artwork; **Add
+artwork** in its library menu can fill missing images later. The artwork
+workflow also covers native Linux and Windows titles added through **Send to
+Frame**. An optional SteamGridDB key under **Settings → Library artwork**
+can supply exact-title community images; source images and generated art are
+fallbacks. See [VR APKs → In the Steam library](vr-apks.md#in-the-steam-library)
+for the limits and tested behavior.
+
+## Set up an emulator
+
+1. In **Store → Emulators**, choose an emulator that supports the console and
+   file format you want. Check its compatibility result before installing;
+   an app listed in the store is not automatically verified on the Frame.
+2. Launch the new shortcut from Steam. Open the emulator's own settings to
+   choose a gamepad layout, core or system, and game folder. These controls
+   differ by emulator; Frame Control does not change them.
+3. Use game files you own and any firmware that emulator's instructions
+   require. Frame Control does not provide ROMs or firmware.
+
+**Android apps run in separate Lepton instances.** Copying a ROM to the
+Frame's Linux `~/Downloads` through **Send to Frame** does not automatically
+put it in an Android app's `/sdcard/Download`. A one-click ROM transfer is
+deferred until an emulator and its file picker can be tested end to end on a
+real Frame. An app's own import or sync feature may be enough. Advanced users
+can use [Lepton's per-instance ADB port](apks.md)
+to copy into that instance, after confirming the correct container and port.
+Do not assume that port 5555 is the emulator: it is Lepton Development, while
+installed apps receive their own ports.
+
+For a native Linux emulator that can read the Frame's home directory, use
+**Send to Frame → Copy to ~/Downloads instead** for your files, then open them
+from the emulator. Whether a particular emulator has a Frame-compatible ARM64
+build, correct controller mapping and readable storage must be checked for
+that app. **Linux apps** in Frame Control lists Flatpak options; a Windows or
+native game archive can instead be added through
+[Send to Frame](sideloading.md#using-it), which registers a Steam title and
+artwork. Each ROM is usually opened *inside* its emulator; Frame Control does
+not create one Steam shortcut per ROM.
+
+## If something does not appear
+
+- Check that the emulator is running and is the same app instance to which
+  you sent the file. Android instances do not share `/sdcard` storage.
+- Check the emulator's supported extension and whether it expects an archive
+  or an extracted file. Some systems need firmware before games appear.
+- For an empty Steam tile, use **Add artwork** in the installed app or
+  sideloaded title menu. This changes artwork, not emulator data or ROMs.
+
+The Frame's microSD/USB path into Android apps remains unverified without an
+inserted medium and an app readback test; see [issue #169](https://github.com/saphid/frame-control/issues/169).

+# Auto-sync retry and headset-selection reliability
+
+Date: 25 October 2026. Base: `d79efb4`, Frame Control v0.4.30.
+Issue: [#214](https://github.com/saphid/frame-control/issues/214).
+Environment: Linux x86_64, Python 3.12.3, Node 24.15.0.
+
+## Reproduced problems
+
+The existing 19 auto-sync tests passed on the base revision. Added regressions
+failed before the implementation: an exhausted clip lost its error, explicit
+retry did not recover failed screenshots or clips, and switches around listing
+or copying continued the old pass. The original callback interface also had no
+way to carry the tick's captured device into the server list reservation.
+
+The final fake-source tests exercise these boundaries:
+
+- Fail screenshots or clips three times, keep checking without further copy
+  attempts, and retain the source error plus an explicit retry instruction.
+- Recover the source and use either Resume or Copy everything now without
+  restarting. Successful copies stay deduplicated; Resume retains the ledger
+  even after a local file is deleted. Copy everything now retains its documented
+  ability to restore deleted files and include older media.
+- Reset an exhausted budget while the source still fails: another three
+  attempts are allowed, rather than unlimited background attempts.
+- Save an exhausted item by hand and clear its stale failure on the next list.
+- Switch after tick captures A, during a list, after screenshot bookkeeping,
+  between media kinds, before a transfer, or before transfer bookkeeping.
+  Interrupted passes do not mark the other headset's IDs or continue copying.
+- Switch to B exactly at callback entry through the production `_sync_list`
+  adapter. `working(A)` refuses before calling the source list, leaving both
+  ledgers and copy callbacks untouched. The same production reservation blocks
+  a device switch during a list and rejects stale screenshot/clip transfers.
+- Execute the production Settings renderer in Node: Resume is available for
+  copy errors and disk-full pauses, and hidden for a healthy state.
+
+## Implementation boundary
+
+Each list callback now receives the captured device, like the copy callbacks.
+The existing server `working(meant)` mechanism checks that intended headset
+under `_work_lock` while reserving work; `devices_post` uses the same lock to
+refuse switches during that work. The worker also checks for interruption
+around lists and transfers. No new device lock or clip destination logic is
+introduced. The server diff is confined to `_sync_list`.
+
+The failed-attempt and error maps are in-memory and reset on explicit retry or
+restart. The successful-copy ledger and settings persistence retain their
+existing format. Disk-full pauses, offline backoff, clip settling and the
+three-attempt limit remain covered by the original tests.
+
+## Checks
+
+- `python3 -m unittest discover -s tests -p test_autosync.py -v`: 33 passed.
+- `python3 -m unittest discover -s tests -p test_shot_copy.py -v`: 2 passed.
+- `python3 -m unittest discover -s tests -p test_clips.py -v`: 34 passed,
+  including local ffmpeg coverage.

+  36 passed.
+- `python3 -m unittest discover -s tests -p test_page_scripts.py -v`: 5 passed.
+- `node --test site/test/*.test.mjs`: 2 test files passed.
+- `python3 -m py_compile ui/frame_autosync.py ui/server.py tests/test_autosync.py`
+  and `git diff --check`: passed.
+
+- `python3 -m unittest discover -s tests -v`: 1,525 tests run in 184.876
+  seconds, passed with 16 skips. Ran with sandbox escalation for loopback
+  sockets; test isolation still used throwaway app/SSH data and mocked headset
+  transport. Final output:
+
+  ```text
+  Ran 1525 tests in 184.876s
+  OK (skipped=16)
+  ```
+
+## Limits and handoff
+
+All new regressions use fake sources and mocked transport; they do not prove
+real-headset transfer or UI rendering. No headset was accessed: its shared test
+lock was held by another task. The Docker fake-Frame end-to-end suite and
+Windows/macOS runs were not performed locally. The coordinator owns review and
+merge; this task does not release, change PR #113, or publish announcements.

+# Packaged Desktop Capture, 2026-10-24
+
+Base: `de931bc`. Package: Linux x86_64 **v0.4.17**. Device: real Frame,
+SteamOS **0.5.6**, BUILD_ID **20261015.6141207**. Host: lxso2.
+[Sanitized state and response evidence](desktop-capture-packaged-2026-10-24.json).
+
+## Result and issue boundary
+
+The packaged app discovered the nested KDE compositor and both automated
+Desktop **Capture** button clicks succeeded. The repeat returned HTTP 200,
+`Content-Type: image/png`, `X-Capture-Source: panel`, and Content-Length
+1,209,980. The app decoded a fresh, nonblank 1920×1080 image and displayed
+the Desktop panel badge. No further product failure was reproduced or fixed.
+
+This does **not** establish the full visible-desktop condition in
+[#73](https://github.com/saphid/frame-control/issues/73). `xwininfo` reported
+the desktop window `IsViewable`, and gamescope confirmed focus after
+`vrcmd --showdashboard valve.steam.desktopgame.0`. However, SteamVR still
+reported that overlay `not_visible`. There was no worn-headset visual check.
+The observation proves capture of a mapped nested compositor, not its visible
+presentation to a wearer. Do not close #73 from this evidence.
+
+The issue screenshot shows a desktop panel in the headset view while Desktop
+Capture logs “no app panel is open in the headset.” The reporter used SteamOS
+0.4.5, gave no Frame Control version or reproduction steps, and has not replied
+to the maintainer's 0.4.3 update request. The duplicate page function was already
+fixed; [PR #152](https://github.com/saphid/frame-control/pull/152) subsequently
+improved unknown-state diagnostics. Its [earlier investigation](panel-discovery-2026-10-24.md)
+was blocked from starting a desktop by another task's lock. This run adds a
+current-package capture observation, without reproducing the older failure.
+
+## Procedure
+
+1. Read-only preflight found Game Mode active, full Plasma inactive, Steam and
+   SteamVR running, battery 99%, no nested desktop/runtime and no test lock.
+2. Compared the retained AppImage's SHA-256 with the live v0.4.17 release asset
+   digest: `b1b8eb82bf73a227b2cd36e8f0ef3a2ebdf7967c5853efb08a9634f38227015d`.
+   Extracted an independent copy; `cmp` confirmed its `frame_touch.py` matches
+   the base checkout. No payload was edited.
+3. Started the package's own AppRun, bundled server and Python on Xvfb `:139`
+   with private config/cache/data/profile, telemetry and update checks disabled,
+   and `--no-sandbox --disable-gpu`. Used the existing authorized `ssh frame`
+   identity. T3 preview opened the package server page but does not attach to
+   the existing Electron window. The literal Electron button test used the
+   same Playwright-over-loopback-CDP workflow as the earlier packaged tests.
+4. Acquired `/tmp/frame-test.lock` with atomic `mkdir` and wrote an owner marker.
+   Rechecked no nested runtime or Plasma was present. Started SteamOS's
+   `/usr/bin/steamos-nested-desktop` in the owned transient user unit
+   `fc-issue73-desktop-20261024.service`, using Steam's display/session variables.
+   `RuntimeMaxSec=180s`, `TimeoutStopSec=15s` and `KillMode=control-group` bounded
+   the session. This launches a desktop panel inside Game Mode; no full Desktop
+   Mode switch was sent.
+5. In the actual packaged Electron window, navigated Tools → Capture & Live →
+   Desktop and clicked Capture with `locator.click()`. The first click event
+   recorded `isTrusted=true`. The page selected the KDE compositor on `:0`;
+   the production screenshot path used window `62914560`. Requested the desktop
+   dashboard, read back focus/visibility, and clicked Capture again. Recorded
+   response metadata, fresh decoded image dimensions and canvas pixel range.
+   No direct screenshot API call was substituted for these button clicks.
+6. Ran the packaged `frame_touch.py panels` read-only over SSH to retain its
+   exact discovery result: one focused KDE compositor panel, app ID 0, 1920×1080,
+   display `:0`, with no diagnostic `why` field.
+
+## Cleanup and limits
+
+The owned desktop session ran **09:43:48–09:45:33 UTC** (105 seconds). Hid the
+dashboard to restore its initial hidden state, stopped only the owned unit,
+and verified it was unloaded/inactive with MainPID 0. No Plasma/KWin desktop
+process or nested runtime remained; gamescope's focusable/focused lists were
+empty again. Released only this task's lock, after checking its owner marker.
+
+Delayed readback at **09:46:39 UTC** confirmed the lock absent, Game Mode active,
+full Plasma inactive and the original Steam, vrserver and vrcompositor PIDs
+still running. The Game Mode service invocation was unchanged. Battery was
+99% at cleanup and 100%/Full on the delayed check. Closed both owned preview
+tabs, Electron and Xvfb; their processes and X socket were gone. No test server
+remained. No reboot, installation, security/global setting change or full
+Desktop Mode transition was performed.
+
+The nested desktop journal included gamescope WSI/Vulkan-hook warnings. No
+warning was dismissed. Capture produced nonblank compositor pixels, but this
+run does not assess their usability to a wearer. Private image files stayed
+outside the repository; only state and response metadata are published.
+
+The initial CDP `response.body()` read yielded zero bytes despite successful
+decoding in the page. The repeat verified the PNG Content-Length, fresh image
+dimensions/source/selection and a 2,011,278-byte PNG exported from the canvas.
+The initial raw-body measurement is a harness limitation, not evidence of a
+product capture failure. No Live video, Control input, physical monitor, FUSE
+mounting or hardware rendering was tested. Older SteamOS and other packages
+remain outside this observation.
+
+## Offline verification
+
+`python3 -m unittest discover -s tests -p test_touch.py -v`: **42 tests passed**,
+including the production page's Node panel behavior tests, duplicate-function
+guard, absent versus empty panel diagnostics, alternate displays, capture/input
+target validation and discovery deadlines. JSON parsing and `git diff --check`
+were also checked. No new regression test was added because this is an
+evidence-only change with no reproduced product defect.

+# Framey loader evidence, 25 October 2026
+
+## Local browser and fake Frame
+
+The official Decky store returned 116 validated entries. ProtonDB Badges was
+entry 14, release 1.3.4, SHA-256
+`90a3453ac02709cad64096e7539fd8141fa56f99ae3441fc24a4990dc9684358`.
+Its published ZIP passed Frame Control's store manifest and path validator. The current
+`dist/index.js` bundle was loaded in an opaque-origin iframe in local Chromium
+with the Framey React/DFL shim. The [browser screenshot](framey-browser-2026-10-25.png)
+shows the plugin's settings panel. A pointer click on **Enable Badge on
+Library** issued `set_setting('settings', …)` through the iframe's request
+bridge. The local test parent returned a stub backend reply; it did not use a
+real headset or Decky backend. A separate fake Frame CEF fixture returned
+`get_setting` and `set_setting` responses through Frame Control's CDP bridge;
+that fixture does not model the real Decky process.
+
+The disposable fake Frame end-to-end harness passed the store catalogue,
+acknowledgement and HTTP auth checks, hash-verified install, update, and
+removal through the real Frame Control HTTP server and SSH transaction. The
+full fake Frame suite passed 48 tests; the full unit suite passed 1,559 tests
+(16 skipped). Unit tests covered unsafe archives,
+unmanaged-folder preservation, asset isolation, backend-call scope,
+and safe aborts of the worn-headset check.
+
+## Real headset status
+
+Read-only SSH on Frame OS 0.5.6 found battery at 98–99%. SteamVR activity was
+initially 3 (standby), briefly 0, then 3 again. During the active probe the
+shared `/tmp/frame-test.lock` belonged to `obs-aacapv3evh-20261025`. It later
+became free after SteamVR returned to standby. Framey did not acquire, replace,
+or remove it. The active probe found no installed Frame Control VR panel or
+Framey plugin; the scripted worn check exited before acquiring a lock or
+altering the headset. There is **no** wearer-visible VR
+menu screenshot, controller-input proof, or live settings-persistence result
+from this round.

+# Framey cache check, 25 October 2026
+
+The official Steam Status 1.2.3 ZIP pinned in
+`tests/fixtures/framey-official/123.zip` was loaded through Framey's local
+HTTP panel in Chromium. The iframe retained `sandbox="allow-scripts
+allow-popups"`, so its native storage remained unavailable. The new Framey
+storage facade accepted a set/get probe without a `SecurityError`. Steam
+Status rendered and issued four `get_settings` calls to a stub parent backend.
+Its `steamstat_last_status` cache entry was about 33 KiB, below the bridge's
+128 KiB cap. After reopening the iframe, the parent supplied the saved cache
+snapshot and the plugin wrote the same cache key again. The browser log had
+zero `SecurityError` or `localStorage` errors.
+
+The parent was a local test page with in-memory Decky backend replies. One
+public status fetch also failed in the test browser, so this check does not
+establish offline correctness or the freshness of Steam Status data. The
+per-plugin save/reopen protocol, stale panel session rejection, and cache
+limits are covered by `tests/page/framey_cache.mjs`. Frame OS persistence,
+live Decky settings, VR visibility, and controller input remain unverified.

+# Framey session cache browser check, 25 October 2026
+
+Frame Control v0.4.34's opaque Framey iframe made the official Steam Status
+1.2.3 frontend log `SecurityError` for its `localStorage` cache. This follow-up
+used a per-panel memory substitute. It did **not** change the iframe's sandbox
+flags or give plugin code Frame Control's UI key.
+
+A local Chromium page loaded the unmodified official Steam Status 1.2.3 archive
+from `tests/fixtures/framey-official/123.zip` (SHA-256
+`9053308e04a74f44745b45b9f4f50af3673348d367e7b14bacc5677de707ac4e`).
+The page used `sandbox="allow-scripts allow-popups"` and returned `{}` for
+four `get_settings` calls. That reply was a stub, not the Decky backend.
+
+The iframe sent `framey:ready`. Its test script wrote and read a cache item.
+The parent could not read the iframe document (`contentDocument` was null).
+The plugin displayed Steam Status, Store, Community, WebAPI, Connection
+Managers and Players Online. Its public status request returned HTTP 200.
+No cache `SecurityError` appeared in the captured console, while the
+same archive had logged that error with the v0.4.34 host.
+
+Node host tests also checked item updates, removal, clear, key order, string
+conversion, quota rejection, and preservation of an existing item after a
+rejected write. The substitute keeps at most 256 items and 512 KiB of keys and
+values **in memory**. Closing or reloading the panel loses this cache. This
+check did not test offline behavior, persistent plugin settings, a live Decky
+backend, SteamVR visibility, controller input, or headset performance.

+# Steam Status in the local Framey browser, 25 October 2026
+
+This check used the unmodified official Steam Status 1.2.3 archive already
+pinned in `tests/fixtures/framey-official/123.zip`. Its SHA-256 is
+`9053308e04a74f44745b45b9f4f50af3673348d367e7b14bacc5677de707ac4e`.
+The archive declares Decky API v2. No headset was contacted for this check.
+
+On a Linux PC, we extracted the archive to a disposable plugin folder with a
+Frame Control store receipt. A local HTTP server served the page from
+`framey_panel.panel(123)`, Frame Control's React 18.3.1 runtime and its
+`framey-host.js`. A parent page put the panel in an iframe with
+`sandbox="allow-scripts"` and returned `{}` for the plugin's `get_settings`
+backend calls. This was a **stub**, not the Decky service.
+
+Chromium reported `framey:ready` and four `get_settings` calls. The page showed
+Steam Status, Store, Community, WebAPI, Connection Managers, Players Online,
+and other controls. Its own public `https://steamstatus.schelstraete.org/api/v1/status`
+request returned HTTP 200 and populated the status view. A click on **Refresh**
+sent Framey's trusted pointer event to the parent; this test did not prove a
+fresh status fetch or settings write. The [browser screenshot](framey-steam-status-browser-2026-10-25.png)
+contains only the local test page and public service data.
+
+The plugin logged `SecurityError` while reading and writing `localStorage` in
+the opaque-origin iframe. It caught the errors and rendered anyway. Its cache
+and offline behavior in Framey are **not verified**. The real Decky backend,
+live settings, SteamVR visibility, controller input and headset performance
+were not tested. This result supports only local frontend rendering for this
+exact archive and Frame Control v0.4.34 host code.

+# Linux PC host feasibility on lxso2, 2026-10-24
+
+**Blocked on this host's current desktop environment. No feature enabled and
+no feature PR opened.** Investigation for [issue #23](https://github.com/saphid/frame-control/issues/23),
+starting at `4e45648` (main after #154). This concerns flat desktop panels,
+not Linux PC VR streaming.
+
+## Decision
+
+The smallest useful candidate is one explicitly selected **whole screen**,
+captured through the ScreenCast portal's restricted PipeWire connection,
+encoded locally with GStreamer/x264, and sent to the existing viewer through
+the shared SSH controller. Input, individual windows and virtual displays
+would remain unsupported until separately verified. This candidate was **not
+implemented**: lxso2 currently cannot exercise the real capture permission path.
+
+Development packages could unblock compilation, but would not create a desktop,
+portal backend or consented screen. Synthetic encoding, an Xvfb screen grab or
+using the Frame as its own host would not verify Linux PC desktop capture.
+No host packages or services were changed.
+
+## Evidence
+
+Host: `lxso2`, Linux x86-64, kernel `6.8.0-139-generic`.
+
+- `DISPLAY`, `WAYLAND_DISPLAY` and `XDG_SESSION_TYPE` were unset. The user bus
+  was reachable at `/run/user/1000/bus`.

+  No processes matched Xorg, Xwayland, Xvfb, GNOME Shell, KWin Wayland, Weston,
+  PipeWire, WirePlumber or xdg-desktop-portal at the process check.
+- D-Bus `ListNames` returned D-Bus, systemd and anonymous connections, with no
+  `org.freedesktop.portal.Desktop`. `ListActivatableNames` also had no desktop
+  portal. These calls queried D-Bus itself without activating capture services.

+## Existing implementation reviewed
+
+- `ui/frame_pcview.py` selects PCView only on Windows and rejects Linux even
+  when enabled. Linux installers do not carry its native bundle.
+- `desktop/portal.c` creates a **RemoteDesktop** session, requests pointer and
+  keyboard devices, and selects monitors and windows (`types=3`). It is not
+  ScreenCast-only or screen-only. Its restricted fd/node and fresh-connection
+  handling are reusable.
+- `ui/frame_pc_agent.py` calls the selection a shared window or screen and
+  picks VA-API when the element is present, falling back to x264. A bounded
+  x264 slice needs explicit encoder policy and unsupported-input behavior;
+  exposing the existing Linux path alone would not meet that scope.
+- `app/main.js` starts Python with the inherited environment; it does not
+  supply a compositor, portal backend or capture permission.
+- `.github/workflows/pc-host.yml` installs native dependencies and tests
+  synthetic x264/protocol behavior with fake capture consent/input. This does
+  not establish interactive Linux desktop capture.
+- Issue #23 and its six existing comments distinguish prior synthetic
+  helper/viewer results from untested Linux desktop capture and consent.
+
+## Verification and limits
+
+`python3 -m unittest discover -s tests -p 'test_pc*.py' -v` exited **0**:
+27 tests ran successfully, with one additional native-class setup skip
+(`native PC libraries not built on this host`). Coverage includes the compiled
+C controller trace, Python adapters, grants and default-off/Windows-only gates.
+It does not prove native GStreamer capture or local-client streaming.
+
+No fake/local native stream, consent prompt, real desktop capture, Frame viewer
+run, benchmark, input or window mode was tested in this investigation. No SSH
+connection to the Frame was needed; no lock was acquired and no headset install,
+launch, stop or settings change was attempted. Issue #113 was left alone.
+No issue comments or other public messages were sent.
+
+## Concrete unblock and next slice
+
+1. Supply an interactive Linux desktop, physical or VM, with a working
+   ScreenCast portal/backend, PipeWire and accessible consent dialog. Installing
+   the portal frontend alone is insufficient. A VM can establish software
+   capture/x264 behavior while physical-host behavior remains unverified.
+2. Install the native dependencies listed in `pc-host.yml` in that environment
+   and build a local `--with-x264` bundle. Resolve x264 distribution
+   licensing/source obligations before shipping it: the current build labels
+   that option test-only and the Windows installer omits it.
+3. Implement a ScreenCast-only session with monitor-only selection, no
+   RemoteDesktop/device request, disabled input in protocol and viewer, hidden
+   window/virtual-display modes, and explicit x264 selection. Preserve the
+   default-off gate and existing Mac/Windows paths.
+4. Verify consent acceptance/refusal/cancellation, Stop/reopen, connection loss
+   and portal closure with a local client decoding actual captured content.
+   Run the shared benchmark and record results without inferring hardware or
+   physical laser behavior.
+5. Only after local capture works, acquire the shared Frame lock once and
+   follow [the headset procedure](../testing.md#headset-smoke-test) for a brief
+   viewer test. If occupied, leave the lock alone and defer device testing.
+
+These are prerequisites and proposed scope, not a ready feature. The Linux
+host request in #23 remains open.

+# Media surround hardening: 2026-10-24
+
+PR [#51](https://github.com/saphid/frame-control/pull/51), branch
+`theatre-media-surround-hardening`, merged main `2ded4c5` without rebasing.
+Both fixes remain necessary on that main: an optional-surround error escapes
+`play()`, and a non-`RuntimeError` during overlay teardown skips the remaining
+handles and OpenVR shutdown.
+
+## Offline checks
+
+- Focused media suite: **23 tests passed** on Linux / Python 3.12.3.
+- Final full suite: **1,381 tests, OK (15 skipped)** in 145.384 s with
+  `PYTHONFAULTHANDLER=1 python3 -m unittest discover -s tests -v`.
+  The service-regression module passed **33 tests**. Player/server compilation
+  and `git diff --check` passed. Current macOS/Windows validation is left to CI.
+- The startup/upload, creation/setup, deferred-surround refusal and teardown
+  regression tests were also run with main's player implementation: they
+  failed as expected (six errors across subtests). The screen-refusal test
+  passed, confirming that actual screen failures still propagate.
+- The historical macOS failure was job
+  [109239733717](https://github.com/saphid/frame-control/actions/runs/36516462623/job/109239733717),
+  on `dac9dbc`, Python 3.12: 619 tests, three failures in artwork resolver
+  tests (`test_resolver_slot_released_when_thread_cannot_start`,
+  `test_timed_out_lookups_are_capped`,
+  `test_url_fetch_refuses_private_hosts_and_honours_deadline`). Media tests
+  passed. Late DNS workers retained semaphore slots; the first failed
+  assertion could also leak acquired slots into later tests.
+- Main already contains `8051687`'s wait-for-idle and unconditional slot
+  cleanup, preserved by `d546568`. The current artwork module passed all
+  **40 tests** locally. No additional artwork changes were needed.
+- The first full run completed **1,380 tests, 15 skipped**, with one failure:
+  `test_a_second_server_is_refused_until_the_first_exits` observed SIGSEGV
+  (`-11`) instead of exit 1. All 41 server tests passed on a focused rerun.
+  Main started daemon index/TLS workers before refusing a second server;
+  its existing shutdown notes document a race with OpenSSL interpreter exit.
+  This crash mechanism is inferred; the first run did not retain a native
+  fault trace. The subprocess assertion now retains stderr for diagnosis.
+  A deterministic regression now checks that rejection starts no listener,
+  cleanup sweep or background workers. It failed before moving the ownership
+  check ahead of startup work and passed afterwards.
+
+The surround retry now logs a refusal before discarding that cosmetic work.
+Creation, setup and first-upload failures also allow the screen to play;
+standby remains retryable, and screen errors remain fatal. Teardown tests
+exercise OpenVR errors, unexpected exceptions and a late `InterruptedError`,
+checking that all handles are attempted and shutdown runs.
+
+## Earlier blocked real Frame attempt
+
+Read-only SSH preflight: SteamOS **0.5.6**, BUILD_ID **20261015.6141207**;
+SteamVR server PID **297506**, compositor PID **297620**; existing media
+service `inactive/dead`, MainPID 0; battery **99%**, fuel gauge `Not charging`,
+charger `Full`. The shared lock was absent at preflight.
+
+The subsequent atomic `mkdir /tmp/frame-test.lock` failed with
+`FileExistsError(17, 'File exists')`: another session acquired it in between.
+The probe stopped before uploading files, launching media, creating overlays,
+or changing any state. The foreign lock was neither modified nor released.
+All generated fixtures remained on the computer and were then removed; no
+headset cleanup was necessary. Steam/SteamVR and the prior player state were
+left alone.
+
+## Follow-up real Frame smoke at the exact PR head
+
+**Passed, 2026-10-24 10:35:02–10:35:23 UTC**, with byte-identical media modules
+from **`5d551a81658d9ff14f49285c28609d506cbc20aa`**. This later run resolves
+the earlier lack of fresh playback evidence. No production code changed.
+The headset was unworn. SteamOS **0.5.6**, BUILD_ID **20261015.6141207**,
+SteamVR **2.18.2**; battery **100%, Full** before and after.
+
+Read-only preflight found Game Mode (`XDG_CURRENT_DESKTOP=gamescope`,
+`start-gamescope` running, no `plasmashell`), Steam/SteamVR running, no media
+overlays, and the installed media service inactive/not loaded. The test then
+acquired `/tmp/frame-test.lock` with atomic `mkdir`; it did not take over a
+foreign lock. Under the lock, those safety conditions were checked again.
+
+Only generated media and the PR's four unchanged modules were uploaded, under
+the test-owned, uid-1000 directory
+`/tmp/pr51-5d551a8-4c0976a52564-utfbk_m0/`. The clip was a **12 s, 30 fps,
+960×540 half-SBS H.264** MP4 with solid red/cyan eye images and **silent AAC**.
+It was generated with FFmpeg's `color`, `hstack` and `anullsrc` sources; no
+personal or external media was used.
+
+The exact `frame_media_remote.run()` Play/status/Stop path was exercised by
+importing its unmodified module and changing only its in-memory `ROOT`,
+`RUNTIME`, `STATUS` and `UNIT` constants to the isolated test locations and
+`frame-control-media-pr51-5d551a8-4c0976a52564.service`. The real
+`frame_media_player.py` ran unchanged with `--layout auto --theatre`, using
+`h264_v4l2m2m` and Pulse output. This checks the player and its systemd lifecycle;
+it does **not** reverify the HTTP/UI upload or runtime installer, nor the
+literal production unit name. The installed media runtime, log, status and
+library were preserved.
+
+- First Play: `starting` → `playing` → **`ended`**, **360 frames**, **160 dropped**,
+  **12.0397 s**, `running=false`. The drops were the normal unworn/standby
+  `SetOverlayRaw` retry path; no fault was forced. At 60 frames, dropped was 0.
+  `vrcmd --overlays` listed `framecontrol.media.surround` as **1×1 visible**
+  and `framecontrol.media.screen` as **visible**. These are SteamVR metadata,
+  not a wearer or eye-capture verification.
+- After EOF: unit **inactive/dead, not-found, MainPID 0**, no test player or
+  decoder, and neither owned overlay remained. Stop after EOF succeeded and
+  retained `ended`.
+- Second Play reached `playing`, 60 frames, 0 dropped. Explicit Stop returned
+  **`stopped`, 72 frames, 0 dropped, `running=false`**. Again the unit was
+  inactive/dead/not-found with MainPID 0, no player/decoder and no owned overlays.
+- The test unit's `ExecStart` and cgroup identified the unique temporary
+  runtime. First-run player/decoder PIDs were **309650/309655**; second-run
+  PIDs were **309805/309810**. Stop controlled only this dedicated test unit.
+  Its player log was empty; no surround refusal or teardown error was logged.

+
+### Cleanup and limits
+
+The temporary directory, including its fixture, code, bytecode, status and log,
+was removed only after verifying that its player and decoder had exited. The
+transient unit was collected. The test released only its own lock after cleanup.
+All installed media runtime file hashes, including `player.log` and
+`status.json`, were unchanged. The installed `frame-control-media.service`
+remained inactive/not loaded. Steam **297826**, vrserver **297506**,
+vrcompositor **297620**, vrdashboard **297721**, and start-gamescope **296997**
+kept the same PIDs. The pre-existing overlay key/dimension/visibility/type
+inventory matched the final inventory, and all dashboard main panels remained
+`not_visible`. No dashboard command, wake request, global setting, reboot or
+Steam/SteamVR stop was issued.
+
+Cosmetic surround refusal and exceptional teardown remain **fake-tested**;
+no real refusal or teardown fault was induced. This short unworn-headset
+smoke does not verify appearance, eye isolation, comfort, audible sound/lip
+sync (the AAC was silent), sustained display performance, or the issue #28
+report of laggy 1080p video. It does not cover new H.265, photo or splat cases.
+Historical checks remain in the earlier PR #51 description and
+[media playback notes](../vr-video.md). The PR remains draft and unmerged
+for parent review and CI.

+# 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)
+records a real Frame stream in OBS on Linux. This follow-up measured the relay
+with an FFmpeg receiver; OBS itself was not relaunched. Windows and macOS
+application paths, wearer-visible image latency, real game sound, audible
+playback, perceptual A/V sync, and active passthrough pixels remain unverified.

+# OBS Media Source on a real Frame, 2026-10-25 AEDT
+
+The Linux x86_64 AppImage from PR #174's exact head `69fff152` had SHA-256
+`4902ac80b77fbf98ec918db29df9cf9260b8abd6763a5b5055572335869f038a`.
+Its extracted resources passed `app/build/check-resources.js`, including the
+OBS helper, and the app launched under Xvfb with an isolated profile and a
+dummy SSH alias. Its bundled server served the page with HTTP 200.
+
+For the device test, the PC was lxso2. The real Frame was reached as `ssh frame`
+under an atomically acquired `/tmp/frame-test.lock`. Battery read 100% Full
+before and after. SteamVR 2.18.2 reported `activity_level: 3` (standby). The
+mirror service and `/dev/video99` were active. The test cleaned its temporary
+remote WAV and released only its own lock.
+
+OBS 30.0.2 ran in a disposable Ubuntu 24.04 container on lxso2, with Xvfb and
+host loopback networking. A Media Source opened `udp://127.0.0.1:15099` with
+input format `mpegts`. A synthetic pattern and tone first verified the OBS
+scene: its saved 43.733-second MKV had H.264 video and AAC audio with a
+`-17.9 dB` audio peak. The real Frame test then ran the helper from the
+extracted AppImage resources **before** OBS opened the source, so OBS joined
+an ongoing stream. OBS's saved 37.600-second MKV had H.264 video and AAC audio.
+The standby mirror appeared in decoded frames by five seconds. A 440 Hz tone
+played briefly to the Frame's default PulseAudio output appeared in the OBS
+audio recording at seconds 20–21; decoded audio peaked at `-34.4 dB`. A
+separate direct recording of `@DEFAULT_MONITOR@` during the same type of tone
+peaked at `-34.5 dB`. These measurements verify non-silent headset output
+audio passed through the helper and OBS into the saved recording.
+
+The first OBS attempt opened its Media Source well before the Frame sent
+packets. Its output had a silent AAC track until the mirror appeared late.
+Starting the helper before OBS fixed this in the second run. The setup guide
+now recommends starting the source in Frame Control before adding or activating
+the OBS Media Source.
+
+The exact-head AppImage was then launched on an isolated Xvfb display and
+profile with the real `frame` alias. In **Tools → Capture & Live**, clicking
+**Start OBS source** changed the UI to **Stop OBS source** and showed
+`udp://127.0.0.1:15099` after the first stream packet. The packaged Python
+helper was running with `--frame frame`. Clicking **Stop OBS source** returned
+the UI to **Start OBS source**; the helper and its remote `/dev/video99` ffmpeg
+process were gone. The app exited through **File → Quit**. Battery again read
+100% Full, and the owned lock was released.
+
+**Limits:** Nobody listened to OBS audio monitoring or the Frame speakers.
+Audio/video sync was not measured. The headset was unworn and in standby, so
+this test does not answer whether active passthrough pixels appear in the
+mirror. The OBS MKVs were temporary local test artifacts and are not included
+in the repository.

+# 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`
+command, OBS installation, SteamOS 3.9.5 VM or physical Steam Machine. This
+check therefore does **not** verify that Frame Control or Flatpak OBS runs on
+a SteamOS desktop or a read-only-root PC host.
+
+The downloaded v0.4.27 Linux x86_64 AppImage matched GitHub's SHA-256 digest
+`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
+with sync bytes. `ffprobe` found H.264 video and AAC audio. Closing the
+helper's control pipe made it exit 0; no owned remote stream process remained.
+Battery read 100% Full before and after, and the owned lock was released. The
+temporary `.ts` file was removed. This proves the local UDP sender path on an
+Ubuntu host; it does not prove Flatpak OBS could receive it on SteamOS.
+
+The public
+[OBS Flatpak manifest](https://github.com/flathub/com.obsproject.Studio/blob/master/com.obsproject.Studio.json)
+lists `--share=network`, which permits use of the host network. We read that
+manifest but did not install or run the Flatpak. A future check needs a real
+SteamOS 3.9.5 desktop host or VM with Flatpak OBS: launch the AppImage without
+root changes, start the source, record from the Media Source at
+`udp://127.0.0.1:15099`, verify video and audible game audio, then stop and
+confirm cleanup. The standby test cannot establish real game audio, A/V sync
+or active passthrough in the mirror.

+# OBS end-to-end validation — 25 October 2026

+**Passthrough: yes.** Real room pixels behind SteamVR panels appeared in the
+live `/dev/video99` mirror, the saved OBS recording, and a decoded frame at
+four seconds in a production MP4. The Frame was safely woken with

+This establishes the checked SteamVR mirror, not every game/mode or Steam's
+own clips. Treat recordings as potentially showing the room.
+
+## 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;

+| 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`.

+# Keyboard and trackpad through gamescope, 2026-10-24
+
+PR: [#66](https://github.com/saphid/frame-control/pull/66), `pad-gamescope`.
+Parent/main: v0.4.18 commit `0da1fe5`. Merge commit: `1737366`, with parents
+`cba23fb` (the existing PR) and `0da1fe5` (main). No history was rewritten.
+
+## Merge and implementation
+
+Both `/api/input` (keyboard/trackpad) and `/api/touch` (live-view Control)
+start and poll the gamescope helper. KDE Connect starts only when Unicode
+typing needs it. The existing ordered, bounded queue and switch cancellation
+remain in place; cross-service typing order is an estimate, not an application
+acknowledgement.
+
+The merge keeps main's intended-device validation and work reservation before
+a GET starts an input helper, immutable SSH routes, launch generations and
+serialized writes. Switching headsets also stops the power report and resets
+both input agents and queued typing before publishing the new route. The page
+keeps main's Tools sections, clipboard controls and single instances of the
+keyboard/trackpad and VR tools, with the PR's gamescope help text.
+
+The start/status regression tests now exercise the gamescope helper for both
+endpoints. An explicit `/api/input` test checks that start and poll use that
+helper without starting KDE Connect. Existing stale/missing-headset and
+route-reservation tests remain active.
+
+## Real Frame: focused click and ASCII keys received
+
+Host: lxso2, `ssh frame`. SteamOS **0.5.6**, BUILD_ID **20261015.6141207**,
+SteamVR **2.18.2**. At **11:05 UTC**, Game Mode was active, full Plasma was
+inactive, Steam and SteamVR were running, battery was **99%**, and gamescope's
+focusable/focused window lists were empty. The shared test lock was absent.
+Existing X11 tools and libX11 were available; Tk could not load its library.
+
+At **11:09:23 UTC**, an initial read-only preflight saw no focused window
+but activity level **0** (idle), rather than the required **3** (standby), and
+aborted before lock acquisition or input. At **11:09:57 UTC**, another task
+held the shared lock with a focused panel; that lock and panel were left alone.
+
+At **11:20:22 UTC**, read-only checks found the lock absent, no focused or
+focusable windows, activity **3** and battery **98%**. The bounded probe ran at
+**11:20:37 UTC** against implementation commit `5641d3c`:
+
+1. Rechecked empty focus and standby, acquired `/tmp/frame-test.lock` with
+   atomic `mkdir`, wrote a unique owner marker and rechecked both conditions.
+2. Created only a disposable 640×400 X11 event-recorder window on `:0`, tagged
+   with test app ID `2000999066`. It had a 45-second alarm and closed on stdin
+   EOF. No existing application, full desktop or dashboard was started.
+3. Waited for gamescope to report that exact window (`62914561`) focused.
+   Started the production server's `TouchAgent` over SSH; it reported ready.
+4. Called production `server.remote_touch` for positioning, then
+   `server.remote_input` with a left click, `Frame66` and the Enter key button.
+   Both responses reported `sent: true`. More importantly, the **window itself
+   recorded ButtonPress/Release (button 1), the ASCII key events in order and
+   Return**. `XLookupString` decoded exactly `Frame66\r`. The events were
+   delivered through gamescope's EIS socket, not fabricated with XSendEvent.
+5. Closed the helper by EOF and waited for exit, closed the recorder, checked
+   empty focus and standby, then removed only the owner-matching test lock.
+
+[State and received events](pad-gamescope-2026-10-24/readback.json) and the
+[probe](pad-gamescope-2026-10-24/probe.py)/[X11 recorder](pad-gamescope-2026-10-24/recorder.py)
+are retained. The archived scripts use checkout-relative source paths; the
+recorded run used the same harness from `/tmp`. Motion records omit an unused
+field that only has meaning for key/button events.
+
+Delayed readback at **11:21:46 UTC** confirmed no test lock or recorder process,
+empty focused/focusable lists, Game Mode active, full Plasma inactive, activity
+3 and battery 98%. The original Steam and vrserver PIDs were unchanged. No
+install, security/global setting change, dashboard/session switch, reset or
+reboot was performed. No headset helper or owned lock remained.
+
+This establishes **focused-panel click and ASCII key delivery on `:0`**.
+It does not establish wearer-visible presentation, Unicode delivery or GUI
+interaction. The absolute-position setup reached the recorder's edge
+(639,399), rather than its centre; pixel-accurate absolute pointing is **not**
+proved by this small-window probe. The trackpad click and typed keys still
+arrived in the owned focused window. The original PR's earlier acceptance-only
+observations remain historical; this observation adds actual window events.
+
+## Offline checks and remaining limits
+
+- `python3 -m unittest discover -s tests -p test_input.py -v`: **58 passed**.
+- `python3 -m unittest discover -s tests -p test_touch.py -v`: **43 passed**.
+- `python3 -m unittest discover -s tests -p test_service_regressions.py -v`:
+  **34 passed**.
+- `python3 -m unittest discover -s tests -v`: **1,403 ran, OK, 15 skipped**
+  (Linux x86_64, Python 3.12; 150.825 seconds).
+- Full fake-Frame e2e in task-specific Docker project `frame-control-pr66`:
+  **47 passed** after the lock fix (192.270 seconds). Both task containers,
+  their network and all three volumes were removed afterward. The run emitted
+  an unclosed test-socket ResourceWarning; the suite returned OK.
+- Node page suites: `ctrl_gestures.mjs`, `pad_queue.mjs`, `desk_panels.mjs`
+  passed, using the production page functions.
+- `node --test app/test/*.test.js`: **3 test files passed**.
+- `node --test site/test/*.test.mjs`: **2 test files passed**.
+- Python compilation, desktop/site JavaScript syntax and `git diff --check`
+  passed. Fake-Frame e2e and exact-head CI results are recorded in the PR after completion.
+
+The first full regression run executed 1,401 tests and found two tests still
+expecting `/api/input` to start the old KDE Connect helper. They were updated
+to the intended gamescope route. The final full run includes the lazy-KDE
+regression above and the lock-order regression below. The initial restricted-sandbox input run could not open
+loopback sockets; the focused rerun with managed network access passed.
+
+Review of the merged code then found a lock inversion: the Unicode worker
+held the pad-send lock while `InputAgent.start()` acquired the route lock,
+whereas a headset switch held the route lock before resetting the pad. A
+bounded subprocess regression reproduced the deadlock with the real
+`InputAgent.send/start` methods and an offline launch stub. Unicode delivery
+and resets now take the route lock before the pad lock; the route lock is
+reentrant so an agent can capture its route inside that reservation. The new
+regression passed after the fix, as did all **58 focused input tests** and
+the **1,403-test full suite** (15 skipped). The local fake-Frame suite also
+passed **47 tests after this fix**. Exact-head CI results are recorded in the PR.
+
+Remaining device work requires an idle, available Frame and the shared lock:
+verify Unicode in a real text field, ordering under real typing load and
+precise absolute pointing for small panels. Worn-headset presentation,
+packaged Electron pointer lock and Windows GUI execution remain separate
+checks. Automated Windows/macOS CI does not establish those interactions.
+
+
+## Review round 2: queue saturation and failure recovery
+
+The coordinator identified silent eviction in both `_queue_for_kde()` and the
+worker's retry path. Both sliced the oldest accepted events off at 200 entries,
+even though the page had already received `sent: true` and discarded its copy.
+
+Admission now serializes concurrent requests, checks capacity before any pointer
+or keyboard send, and returns `sent: false, state: waiting` if the whole batch
+will not fit. Text stays in the bounded queue while in flight, and is removed
+only after the helper accepts it. Rejected mixed batches send no clicks; retrying
+them cannot duplicate clicks already sent by this server. The page polls until
+it can retry. Pointer input stays usable while accepted text is pending.
+
+The old worker also left its worker marker and one-hour timing sentinel behind
+if `send()` raised. Failure/timeout handling now retains unsent text, clears the
+worker/timing state and exposes an error through input status. The page polls
+accepted text without requiring another keypress. **Try again** explicitly
+restarts the retained queue. Thread-start failures follow the same retention
+rule. A stale worker's exception cannot change the new route's state.
+
+The proposed send-to-enqueue headset-switch race was not reachable through the
+normal HTTP switch path: `Handler.do_POST()` reserves `working(meant)` across
+both operations; `devices_post()` shares `_work_lock` and refuses a moving
+operation while work is active. Connector configuration/reconnect paths defer
+changed headsets while work runs. A production-handler regression attempts a
+switch at both send and enqueue and passes even on the previous implementation.
+No separate connector change was needed. Atomic queue admission now uses the
+existing route-before-pad lock order as well, because starting either input
+agent can capture its route synchronously.
+
+Three deterministic saturation regressions fail on `215db7b` and pass with the
+fix: capacity during the typing delay, capacity during an unsuccessful-send
+retry, and two concurrent producers competing for the last slots. They check
+exact accepted event sequences, reject a mixed click/text batch before its
+pointer effects, and verify delivery exactly once after retry. Additional tests
+cover explicit recovery after timeout, helper errors, send exceptions and
+thread-start failure, stale-worker isolation, HTTP status/start behavior, and
+the production page's polling/error behavior.
+
+No new active headset test was performed: this change affects host queue
+admission/recovery and status handling, not Frame event translation or injection.
+The earlier real click/ASCII evidence remains scoped to its recorded commit.
+Real Unicode, packaged Electron pointer lock, Windows GUI, wearer-visible
+presentation and precise small-window absolute positioning remain unverified.
+`sent: true` means accepted by this server, not application delivery. The queue
+is in memory; switching headsets cancels it and server exit loses it. A transport
+failure after a partial write can still make delivery ambiguous; this is not an
+end-to-end exactly-once protocol.
+
+Round 2 local verification: **141 focused input/touch/service tests passed**
+(62 input, 43 touch, 36 service; 20.061 seconds), and **1,409 server tests ran, OK, 15 skipped**
+(Linux x86_64, Python 3.12, 153.198 seconds). All three production-page Node
+suites passed; app tests passed (3 files), site tests passed (2 files), Python
+compilation and `git diff --check` passed. The existing skipped tests require
+zsh, macOS/Swift or built native PC libraries. Current-head CI is tracked in
+PR #66; the previous 47-test local fake-Frame run above is historical.

+# Panel discovery investigation, 2026-10-24
+
+Base: v0.4.16 (`040581a`). Scope: issue #73, Desktop Capture and Control.
+
+## Evidence and change
+
+Issue #73 reports SteamOS 0.4.5 with its desktop visibly running, without a
+Frame Control version or steps. The maintainer's 2026-10-12 comment identifies
+the duplicate `loadPanels` UI function fixed in 0.4.3 and requests the exact
+remaining message and SteamOS build if it persists. There is no reporter
+follow-up. At this base, the functions are distinct and the existing Node
+regression checks their uniqueness and the Desktop GET request.
+
+Read-only source inspection found a remaining diagnostic ambiguity:
+`read_props()` returns `{}` for failed/timed-out X queries and missing root
+properties. `panels()` treated that like a confirmed empty focusable-window
+list. With no detected Plasma process it claimed no panel was open; with Plasma
+it claimed SteamOS was not listing the desktop. Neither claim follows from an
+unreadable list.
+
+The change checks for the presence of `GAMESCOPE_FOCUSABLE_WINDOWS` before
+those claims. An absent list now reports unknown panel state, suggests checking
+SteamVR and retrying/Headset view, and asks for the exact message and SteamOS
+version if persistent. Missing-tool and whole-run deadline explanations retain
+precedence. No new probes, retries, timeouts, input or capture routes are added.
+
+## Real-device boundary
+
+A preliminary read-only SSH inspection returned SteamOS 0.5.6, BUILD_ID
+`20261015.6141207`, battery 99%, discharging, and X0/X1 socket names. It made
+no headset changes. The shared lock was absent at that moment.
+
+The subsequent atomic `mkdir /tmp/frame-test.lock` failed with `File exists`.
+The guarded command exited with status 3 before the session, X-property or
+panel-helper probes ran. The other task's lock was left alone. No application
+was installed, started, stopped or focused; no headset settings changed.
+
+That implementation probe was blocked by the occupied shared device. The
+coordinator later supplied a separate narrow read-only observation on SteamOS
+0.5.6, BUILD_ID `20261015.6141207`, at battery 99%, with the shared lock absent
+and both `xprop` and `xwininfo` installed:
+
+- In **Game Mode**, `DISPLAY=:0 xprop -root GAMESCOPE_FOCUSABLE_WINDOWS
+  GAMESCOPE_FOCUSED_WINDOW` returned both properties **present but empty**.
+- On `DISPLAY=:1`, both properties were reported **not found**.
+
+This observation distinguishes a confirmed empty list on `:0` from absent
+properties on `:1`. It does **not** reproduce #73's Desktop Mode report on
+SteamOS 0.4.5, and it does **not** test this PR's code on the headset. It is a
+coordinator-supplied observation, separate from the blocked implementation probe
+above; no new headset probe was run for this follow-up.
+
+Remaining limit: there is no reproduction establishing a further
+capture/discovery fix for the reported Desktop Mode/build combination. This PR
+improves a demonstrated diagnostic error; it must not close #73 as a verified
+new capture fix.
+
+## Offline verification
+
+Focused Python regressions distinguish absent, focus-only, failed/timed-out X
+queries, confirmed empty and desktop-running lists. Existing tests cover
+missing tools, alternate displays, successful discovery and the 12-second
+deadline. The production page's Node behavior test verifies that both Capture
+and Control preserve the unreadable-list advice. These use fake X/HTTP/DOM
+boundaries and do not prove real SteamOS 0.4.5 capture or physical input.

+# Saved panel layouts: feasibility recheck, 2026-10-24
+
+Issue: [#31](https://github.com/saphid/frame-control/issues/31). Base: main
+`5b47cd3`. This investigation covers spatial save/restore for existing
+Steam/gamescope panels without another overlay application.
+
+## Decision and user behavior
+
+Keep saved layouts unavailable. The current Frame exposes some geometry,
+including a standing-space coordinate transform, but this investigation did
+not establish a complete dock-state snapshot or a controlled restore path for
+these panels. The existing companion/headset switcher still lists panels and
+requests focus; users arrange them with SteamVR's dashboard controls. No layout
+file, new control, overlay application or background service is added.
+
+This is a limit of the investigated route, not proof that every native
+implementation is impossible. In particular, failure of
+`GetOverlayTransformAbsolute` does **not** mean all pose readback is denied.
+
+## Device and read-only results
+
+SteamOS **0.5.6**, BUILD_ID **20261015.6141207**; `vrcmd --version`:
+**2.18.2**. `gamescope-session.service` was active and
+`plasma-workspace.target` inactive: Game Mode. gamescope used the OpenVR backend
+and `--virtual-connector-strategy PerAppId`. Battery was 99%, Not charging,
+before the probe and 100%, Full, afterwards.
+
+The [exact probe](panel-layout-2026-10-24/probe.py) loads only
+`FnTable:IVROverlay_028` from the shipped
+`/opt/steamvr/bin/linuxarm64/libopenvr_api.so`. It uses application type 3
+(`VRApplication_Background`, avoiding runtime startup) and shuts down its own
+OpenVR connection in `finally`. Initialization and interface acquisition both
+returned 0. It calls getters only, with no image capture or input injection.
+
+[Raw result](panel-layout-2026-10-24/readback.json):
+
+| Getter | `valve.steam.desktopgame.0` | `valve.steam.gamepadui.main` |
+|---|---|---|

+The dashboard and both panels were reported hidden; neither panel was active.
+The standing-space matrix is the transform for the overlay point `(0.5, 0.5)`;
+it does not identify World/Dashboard/Theater/controller docking or recreate a
+dashboard frame. The Steam panel's basis has scale about 0.369. Treat neither
+that scaled matrix nor the hidden Gamescope panel's identity as a validated
+physical placement to feed to an absolute-transform setter. Visible placement,
+matrix freshness and correspondence to dashboard size were not checked by a
+wearer.
+
+## API and dashboard boundary
+
+The ABI and result names were checked against Valve's
+[OpenVR v2.12.14 C header](https://github.com/ValveSoftware/openvr/blob/v2.12.14/headers/openvr_capi.h)
+and [C++ interface comments](https://github.com/ValveSoftware/openvr/blob/v2.12.14/headers/openvr.h).
+That header declares `IVROverlay_028`; its SHA-256 is
+`d58a2b149e434b2b8ee25cb4253ca6157feed8092f621e78ecfed6846d35d3e4`.
+The absolute getter is explicitly limited to absolute transforms. The
+coordinate getter returns the 3D transform for a 2D overlay point. Public
+`IVROverlay_028` has no getter/setter pair for dashboard dock location or frame
+scene-graph state. The probe fails closed if that exact interface is absent.
+
+Read-only inspection of the shipped dashboard
+`/opt/steamvr/resources/webinterface/dashboard/chunk~8012d0c89.js`
+(SHA-256 `937ec62c67a481f030a416099ceb98b0fe2a702aea5a0705601c6c40d4969f6d`)
+found:
+
+- `dockLocation` reads an internal `_getDockLocation(frameID)` store;
+  `SetDockLocation` updates that store or sends a VRLink request.
+- `m_mapLastRelativeTransformForDockLocation` keeps per-location transforms.
+  World initialization requests a dashboard scene-graph transform through
+  `requestSGTransform`, then updates the component's `xfTransform`.
+- The `vrcmd_dock_overlay` handler accepts `dashboard`, `lefthand`, `righthand`,
+  `theater` and `world`. It selects the frame associated with the supplied key,
+  **falls back to the active frame if no match exists**, sets dock location and
+  may switch frame. This is not an exact pose restore or a readback response.
+
+Those are observations of shipped internal code, not proof that Frame Control
+can safely access its state through a supported external API. No dashboard
+JavaScript was injected, private store edited or VRLink command sent. The
+active-frame fallback is an additional reason not to experiment with docking
+commands on a stale key.
+
+The [2026-09-28 probe](../panels.md#saved-spatial-layouts-blocked-on-the-current-panel-route)
+on SteamOS 0.4.1 / SteamVR 2.18.1 recorded an absolute setter returning
+12 (`PermissionDenied`) on a temporary, test-owned gamescope panel. That setter
+result is **historical**, not a new test on 2.18.2. The newer read-only results
+above neither overturn nor reverify it.
+
+## Commands, safety and cleanup
+
+Read-only inspection used `ssh frame` with `BatchMode=yes` and
+`ConnectTimeout=10`, `cat /etc/os-release`, battery sysfs reads,
+`systemctl --user is-active gamescope-session.service plasma-workspace.target`,
+process inspection, and `vrcmd --version`, `--help`, `--overlays`. An initial
+`--listoverlays` attempt returned `Unknown command`; `--overlays` is the actual
+enumeration command. Dashboard sources were read/copied to local `/tmp` for
+inspection. No files were installed on the Frame.
+
+Run the retained probe from the repository root, following
+[the shared-device rules](../testing.md#headset-smoke-test). Stop if the lock is
+occupied or battery is at/below 20%; never remove another task's lock:
+
+```sh
+ssh -o BatchMode=yes -o ConnectTimeout=10 frame \
+  'set -eu; mkdir /tmp/frame-test.lock || exit 3; trap "rmdir /tmp/frame-test.lock" EXIT; timeout 25 python3 -' \
+  < docs/evidence/panel-layout-2026-10-24/probe.py
+```
+
+This command acquired the lock, completed with exit 0 and released it. A
+subsequent check confirmed the lock absent, Game Mode active, and Steam,
+`vrserver` and `vrcompositor` running. The probe's only headset filesystem
+change was creating/removing that shared lock. Its Python source ran from
+stdin. There were no test panels, installs, profiles or services to remove.
+
+No mutation test was essential: without verified dock/relative-frame readback,
+there was no exact original layout and bounded rollback to justify changing a
+panel. Existing user panels were never focused, shown, hidden, resized, moved
+or docked. No global settings, security, passwords, runtime processes or modes
+were changed; no reboot or reset occurred.
+
+## Validation and remaining gaps
+
+Existing `tests/test_panels.py` covers main-panel enumeration, hidden panels,
+focus revalidation, unavailable-runtime errors and HTTP authentication/Host/
+Origin guards. `tests/test_page_scripts.py` checks the production page's shared
+JavaScript scope. These offline checks do not prove spatial placement. The
+retained probe is evidence tooling, not a new product API; no fake layout
+backend or layout tests claiming device support were added.
+
+Validation passed:
+
+```sh
+python3 -m unittest discover -s tests -p test_panels.py -v       # 8 passed
+python3 -m unittest discover -s tests -p test_page_scripts.py -v # 5 passed
+python3 -m py_compile docs/evidence/panel-layout-2026-10-24/probe.py
+python3 -m json.tool docs/evidence/panel-layout-2026-10-24/readback.json
+git diff --check
+```
+
+The initial panel-suite attempt hit sandbox socket restrictions in four HTTP
+tests; rerunning with loopback sockets permitted passed all eight. No real
+headset connection is used by those tests. The full suite and fake Frame were
+not run for this evidence-only change.
+
+Before shipping layouts, a native route still needs proof of dock state and
+relative-frame readback, authorized restore on an owned test panel with exact
+rollback, and correspondence between saved size/pose and visible placement.
+It also needs stable source identity and a fresh capture-permission/ticket
+flow when reopening viewers. Reconnect, panel recreation, reboot recovery,
+Steam-launched gameplay, controller docking and worn-headset input were not
+tested here. The existing Frame Control-owned media renderer is not proof that
+Steam/gamescope panels can be restored. No third-party overlay app was used.
+
+## Announcement
+
+We rechecked saved panel layouts on SteamOS 0.5.6. SteamVR exposes some panel
+geometry, but we have not verified safe restoration of Steam's panel positions
+and docking. Saved layouts remain unavailable; use SteamVR's dashboard to
+arrange panels. The panel switcher continues to list and show open panels.

+# Round 2 retry, 25 October 2026
+
+The provider retry completed four further fixes, each in an isolated child
+worktree with its own issue, branch, PR, tests, docs and Announcement draft.
+The coordinator reviewed each patch, independently ran focused tests, verified
+its exact head and complete CI, merged it, then read back GitHub's merged state.
+PR #113 was untouched. No social announcements were posted.
+
+## Merged fixes
+
+| Change | PR | Merge commit | Coordinator focused tests | Final CI |
+| --- | --- | --- | --- | --- |
+| Skip linked backup ancestors and recheck before packing | [#215](https://github.com/saphid/frame-control/pull/215) | `da34d94` | 34 passed | 11 checks passed at `8cc03c8` |
+| Clean orphan smoke metadata/shortcuts; POSIX runner without zsh | [#216](https://github.com/saphid/frame-control/pull/216) | `d5fa8fe` | 17 passed | 10 checks passed at `a5daa4a` |
+| Separate Steam clips by headset/account/full session ID | [#217](https://github.com/saphid/frame-control/pull/217) | `1255ef2` | 62 passed | 10 checks passed at `7dfe777` |
+| Retry failed automatic copies and bind listings to the captured headset | [#218](https://github.com/saphid/frame-control/pull/218) | `fdd60d3` | 33 passed | 10 checks passed at `af2bb17` |
+
+Two initial CI fixture failures were fixed before merging: macOS temporary-path
+aliases needed a resolved working directory in the wrapper test; Windows
+needed explicit UTF-8 when reading the Settings test's HTML fixture.
+Concurrent main changes #208/#209/#210 were preserved. Changelog conflicts
+retained both entries. No history was rewritten.
+
+## Integrated validation
+
+At main `1255ef2`, after all four merges:
+
+- `python3 -m unittest discover -s tests`: 1,559 tests, 16 skipped, passed in
+  157.335 seconds. Loopback networking was enabled for local HTTP fixtures.
+- `node --test app/test/*.test.js site/test/*.test.mjs`: 59 tests passed.
+- Worker backup validation also passed both Docker recovery-kit E2E tests in
+  an isolated Compose project, then removed its containers, volumes and network.
+- Local proof logs: `/tmp/frame-round2-integrated-tests.log` and
+  `/tmp/frame-round2-integrated-node.log`. Individual focused logs use
+  `/tmp/frame-round2-{backup,smoke,clips,autosync}-review.log`.
+
+## Real Frame smoke
+
+The current host is lxso2; its existing direct `ssh frame` alias works.
+Another OBS task initially held `/tmp/frame-test.lock`, so only read-only
+checks were done until it released the lock. This coordinator then acquired it
+atomically and labeled it `frame-round2-vdw4yh1xv8-20261025`.
+
+The merged `scripts/frame-smoke.sh` ran directly without zsh at 06:38:37 UTC.
+All 13 steps passed on SteamOS 0.5.6, BUILD_ID `20261022.6153909`. The ARM64
+and Proton titles ran. The x86-64 Linux title reported its runtime missing,
+an explicitly accepted smoke outcome rather than a successful execution.
+Installs/removals succeeded; the Windows title's remove
+step stopped five test-owned PIDs. Both final process sweeps were empty.
+Independent readback found no reserved title folders or metadata, SteamVR's
+PID was unchanged, and the three observed gamescope focus properties matched
+before/after. Battery went from 99% Charging to 100% Full. Only this task's
+lock was removed, and its absence was verified.
+
+[Sanitized structured proof](round2-smoke-2026-10-25.json). Raw local results:
+`/tmp/frame-round2-smoke-results/2026-10-25T063837Z-20261022.6153909.json`;
+console log `/tmp/frame-round2-headset-smoke.log`; state readbacks
+`/tmp/frame-round2-smoke-before.txt` and `/tmp/frame-round2-smoke-after.txt`.
+
+The headset was unworn. Visible rendering/controller input was not verified.
+No pairing, password/security change, reboot or factory reset was performed.
+The new backup/clip/auto-sync paths have local fixtures and cross-platform CI;
+this smoke does not establish a new real-data backup/clip/UI test. Synthetic
+orphan metadata was not seeded on the real device. Backup path checks retain
+a documented race with concurrent filesystem changes.
+
+## Prior round-two work reconciled
+
+The failed coordinator checkout was still at v0.4.7. It was first updated to
+main `d79efb4`, already v0.4.30. Earlier PRs had completed clipboard testing
+(#124), original smoke process cleanup (#126), Windows VM capture (#129),
+battery health (#125), setup doctor (#127), and read-only storage (#128).
+Later evidence already covered real clip export (#147/#149/#154/#156) and
+Return to Game Mode (#143/#157). These remain earlier evidence, not tests
+performed by this retry. Physical Windows GPU/input and current physical
+macOS checks remain incomplete; see the current support matrix.
+
+Decision: fix reproduced data/cleanup/retry defects rather than automate game
+moves without a verified transaction API or promise unverified phone-background
+sync. Prepare v0.4.31; publication still requires its Linux AppImage install test.
+
+## Delegation provenance
+
+All implementations completed. Task IDs use prefix
+`node:delegated-task:command%3Amcp%3Ad9bc35d8-0e9c-42c2-b798-25bd8af94d81%3Adelegate-task%3A`

+# Round 3 headset checks, 25 October 2026
+
+These checks used the real Frame after the device hold ended. SteamOS was
+0.5.6, build `20261022.6153909`. Each device session acquired
+`/tmp/frame-test.lock` atomically and released only its own lock. The battery
+read 100% and Full in the first check and after the OBS session; Steam and
+SteamVR were left running.
+
+| Question | Observation | Conclusion |
+|---|---|---|
+| Does active passthrough appear in SteamVR's `/dev/video99` mirror? | The mirror service was active. One 1920×1080 RGB frame read from `/dev/video99` had a single pixel value, `(24, 28, 53)`, throughout. The headset was unworn; no active passthrough session or wearer-visible room view was established. Frame Control has no verified remote passthrough toggle. The temporary frame was removed. | **Still unknown.** A uniform standby frame cannot answer whether SteamVR composites active passthrough into its mirror. No headset setting was changed. |
+| Can Frame Control prompt when a headset text box opens? | No desktop `plasmashell` process was running during this check. There is no verified cross-app focus event from SteamVR, Lepton and the nested desktop; KDE Connect's `keyboardstate` packet describes keyboard support, not a focused text field. | **Not built.** A prompt triggered by an unverified signal would be misleading. The existing **Type on the headset** control remains available. |
+| Does reverse clipboard exist? | Frame Control already has **Copy the headset's clipboard here**. Its earlier real Frame test used a temporary nested desktop and confirmed that text copied through Klipper reached a Linux PC clipboard. No desktop panel was open during this session, so it was not rerun here. | **Shipped and previously verified**, text only. Windows/macOS backends and arbitrary headset apps remain unverified on a real Frame. |
+| Is an 80% charge limit available and writable? | `steamosctl get-max-charge-level` returned `UnknownInterface: ...BatteryChargeLimit1`. No `charge_control_*` attribute was found under `/sys/class/power_supply`. Only `pm8550b-charger/charging_pause` and `charging_enable` were present, each mode `644`, owner `root:root`. | **No supported user-writable control.** No battery attribute was written. |
+
+The separate OBS transport check on the same build sent the mirror and the
+default-output monitor to a Linux PC. A 4.021-second temporary capture had
+H.264 video and AAC audio according to `ffprobe`. It was removed; OBS itself
+and audible playback were not tested. See the OBS source PR and guide.

+# 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.

+# Steam clip export collision fixtures, 25 October 2026
+
+Base: `d79efb4` (Frame Control v0.4.30). Issue:
+[#212](https://github.com/saphid/frame-control/issues/212).
+Host: Linux 6.8.0-139-generic, Python 3.12.3, ffmpeg 6.1.1.
+
+## Baseline reproduction
+
+Loaded the unmodified `ui/frame_clips.py` from `d79efb4` into a temporary
+Python module and exported three fake sources into a temporary directory:
+
+```
+1/clips/clip_620/video/bg
+2/clips/clip_620/video/bg
+1/clips/clip_620/video/other
+```
+
+Each source's payload was its own ID. All three exports returned the same
+destination, `clip_620.mp4`; listing marked all three saved. The final file
+contained only the last source ID. No SSH or headset was used.
+
+## Regression coverage
+
+`tests/test_clips.py` exports five IDs on each of two fake headsets, including
+equal clip names across accounts, nested sessions with equal leaf names,
+different leaf names under one clip and the background/clip distinction.
+All ten payloads survive at distinct destinations. Listing marks only the
+identities already exported. A pre-existing flat MP4 retains its original
+bytes and does not mark any identity saved. Normal export still returns
+`message` and `file`, removes its remote temporary export and clears local
+staging; a failed re-export preserves the completed file.
+
+`tests/test_clip_copy.py` exercises the server's list and manual export
+functions and its actual auto-sync callbacks with fake transport. A manual
+copy is recognised by auto-sync, all other account/session identities copy,
+and switching to a second headset copies its own sources without overwriting
+the first. A delayed manual job refuses a changed headset with status 409.
+Both local phone mode and local headset runtime reject Steam clip list,
+export and auto-sync requests with status 400. The separate `Recorder` path
+is unchanged.
+
+## Validation
+
+- `PYTHONPATH=tests python3 -m unittest test_clips test_clip_copy test_autosync test_shot_copy test_headset_actions -v`
+  — 66 tests passed in 17.288 seconds, no skips. Includes real ffmpeg/ffprobe
+  export of a generated 65-second DASH fixture and recording stop/cleanup.
+- `PYTHONPATH=tests python3 -m unittest test_server -v`
+  — 44 tests passed in 12.315 seconds, no skips.
+- `node --test site/test/*.test.mjs` — 2 tests passed.
+- `python3 -m unittest discover -s tests -v` — 1,518 tests run in
+  181.025 seconds; OK, 16 skipped for unavailable platform/tool prerequisites.
+- `python3 -m py_compile ui/frame_clips.py ui/server.py tests/test_clips.py tests/test_clip_copy.py`
+  and `git diff --check` — passed.
+
+The server and full Python suites require localhost sockets and were run
+outside the network sandbox. Tests import `tests/sandbox.py` to isolate app
+data, SSH settings, home directories and service URLs.
+
+## Limits and upgrade behaviour
+
+No real headset was accessed: the shared device lock is held by other work.
+This is Linux fixture and server coverage, not a fresh packaged-app or
+Windows/macOS verification. Existing real-headset export evidence in the
+recording guide predates this destination change.
+
+Old flat exports cannot prove headset/account/session identity and are left
+untouched. Previously remembered auto-sync IDs retain their existing
+watermark/history behaviour; **Copy everything now** or manual **Export**
+creates an identified copy. No release, version bump, merge or social post
+is included. PR #113 is outside this task.

+# SteamOS 0.5.6 compatibility check, 25 October 2026
+
+The real Frame was accessed **after** the 00:00 AEDT hold, under a separately
+acquired `/tmp/frame-test.lock`. The coordinator had finished its v0.4.19 smoke
+test and released its lock first. This check took place approximately 00:04–
+00:08 AEDT (13:04–13:08 UTC). A device clock reading in the first snapshot was
+**00:04:58 AEDT**. The one temporary capture was removed and our lock was
+released. Steam and SteamVR were left running.
+
+| Check | Observation |
+|---|---|
+| OS | `VERSION_ID=0.5.6`, `VARIANT_ID=vr`, `BUILD_ID=20261022.6153909` |
+| Update channel | `atomupd-manager tracked-branch` returned `beta`; tracked variant `vr`; update status `idle`. `atomupd-manager status` and `check` returned D-Bus `AccessDenied` to the normal user. No root, update, or channel change was attempted. |
+| Discovery | `frame.local` and a sample `frame-0000.local` name were unresolved from the Linux host. Avahi was active on the Frame, but `/etc/avahi/avahi-daemon.conf` has `publish-addresses=no`. The configured `ssh frame` alias worked. The host reached the Frame over Tailscale, so a local-subnet scan and same-LAN cached-IP reconnection were not exercised. |
+| Script fallback | `steamos-session-select` was present and `holo-session-select` absent. The installed devkit utilities contained `steamos-prepare-upload` and `steamos-delete`; their `holo-*` replacements were absent. No session switch, install, or delete command was run. |
+| Battery and memory | Frame Control's `ui/frame_status.py` returned a system battery at 98%, Charging, with its source under `/sys/class/power_supply/max1720x_bat_7-36`; memory was 16,422,952,960 bytes total and 11,256,848,384 bytes available. The battery was 97% at the initial raw sysfs check and 98% at the final check while charging. |
+| Recording source | The user `steamvr-v4l2cam.service` and `/dev/video99` were present. A single frame from that device was black while the unworn headset was in standby. Frame Control's MP4 path reads that same SteamVR `system.HeadsetView` mirror and never opens a passthrough camera. Active passthrough inclusion in the mirror remains unverified. The sample image was not retained or published. |
+| Dominant eye | Neither standard `steamvr.vrsettings` path checked had a readable dominant-eye setting. No source or effect on the mirror was verified; Frame Control does not attach dominant-eye metadata. |
+
+This was a bounded compatibility check, not a rerun of the coordinator's
+13-step smoke test. The coordinator reported that smoke passed on this same
+build, with battery 95% to 96% while charging and cleanup complete.

+- [Capture before the fix](windows-vm-2026-10-24/capture-before.json): five
+  synthetic H.264 frames and five JPEG frames; zero desktop/window frames,
+  with the missing-property error for both codecs.
+- [Actual bundled properties](windows-vm-2026-10-24/plugin-properties.json):
+  `monitor-handle` exists; `capture-api`, `window-handle`, `show-border` do not.
+  [MSYS2 package build](https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-gst-plugins-bad/PKGBUILD)
+  sets `-Dd3d11-wgc=disabled`. Upstream
+  [installs those properties conditionally](https://github.com/GStreamer/gstreamer/blob/main/subprojects/gst-plugins-bad/sys/d3d11/gstd3d11screencapturesrc.cpp).
+- [Capture after the fix](windows-vm-2026-10-24/capture-after.json): the real
+  display produces five H.264 and five JPEG frames. Window sources are hidden
+  with an explicit reason, and the display selects `capture_api=dxgi`.
+- [Raw locked headset session](windows-vm-2026-10-24/headset-session.json):
+  Windows helper, Media Foundation encoder, reverse SSH tunnel, production
+  panel launcher and shared viewer. The image below was captured from that
+  viewer's own X window on the Frame, rather than the VM's console.
+- [Windows tests](windows-vm-2026-10-24/windows-tests.txt) and
+  [guest system details](windows-vm-2026-10-24/windows-system.txt).

+
+## Host and VM prerequisites
+
+lxso2: Intel Core i7-8700, 12 logical CPUs, VT-x/KVM; Docker 29.1.3 and Compose
+2.40.3. Before starting: 31 GiB RAM, 15 GiB available; 147 GiB free disk.
+Swap was already full. No other VM or service workload was started or stopped.
+Docker listed no Windows VM, and ports 2222/8006/13389 were unused.
+
+The execution sandbox hid KVM and denied Docker/network access. Checks outside
+it found `/dev/kvm`, `/dev/net/tun` and the Docker daemon. Direct user access to
+KVM was denied, but a disposable Docker container with `--device /dev/kvm`
+opened it successfully; no host permissions changed.
+
+Created only `frame-winvm-priority3`, labelled
+`frame-control.task=priority3-windows-test`: 4 vCPUs, 8 GiB guest RAM, 32 GiB
+growable disk, no restart, 150-second stop timeout. SSH 2222 and console 8006
+bind only 127.0.0.1; RDP is unpublished. No GPU passthrough. Image:
+`dockurr/windows@sha256:16fd7c39a3e48bb946d29c59dc6015942e5b900a1fa5d7e5552053bfc48ee2ea`
+(Windows for Docker v6.06, QEMU v11.1.1).
+
+The container downloaded Windows 11 from Microsoft, with no activation changes.
+It took about 16 minutes to reach the first desktop. Guest build 26200.8037,
+Red Hat VirtIO GPU DOD driver 100.103.104.30200. The old WindowsProductName
+registry field still says Windows 10 Pro; the actual desktop/setup is Windows
+11. After installing the app, the 32 GiB disk had about 9.3 GB free.
+
+Official `Frame-Control-Setup-x64.exe` v0.4.10 SHA-256:
+`30165bc5aa39f941cacc697d195dc5c30b01ad0b9ffb472da8a18a5220549202`.
+Its installer exited 0. The VM stream used an intermediate Python/UI-only
+fix with the released DLL bundle and bundled Python 3.12.14. A later CI failure
+showed that probing GStreamer through a separately loaded DLL could see a
+different, uninitialized instance. The final fix probes optional properties
+through the capture DLL itself. Windows CI checks that native change; the VM
+stream was not repeated with the final DLL.
+
+OEM setup added OpenSSH Server, PowerShell and a dedicated public login key;
+password authentication is disabled. Its config needed an explicit
+`AuthorizedKeysFile C:/ProgramData/ssh/administrators_authorized_keys` before
+key login worked. The default informational share was replaced with a private
+writable staging share inside this container. These were test-VM setup steps,
+not app defects. Host setup files and the stopped VM disk are retained under
+`/tmp/frame-winvm-priority3/`; no private keys are committed or printed.
+The Frame test key was generated inside Windows and its private key stayed
+there. Only its public key was temporarily authorized on the Frame. After
+testing, the guest key and scheduled task were removed; `docker stop -t 150`
+shut down the dedicated VM. Inspection confirmed `exited`, restart `no`
+(container exit 143; logs show the ACPI shutdown signal, waiting for Windows,
+and `Shutdown completed!`). The disk is retained
+for reuse; the VM is not running.
+
+## Checks
+
+- Baseline PC-focused suite: 24 tests passed, one native class skipped.
+- After fix: full Linux unittest suite **1260 tests, OK, 15 skipped**, 144.366 s;
+  focused final PC suite **27 tests, OK, one native class skipped**. The C
+  controller's frozen 600-state trace ran on Linux.
+- Actual Windows installer bundle with the intermediate Python/UI fix:
+  **33 tests, OK, four skipped** (no C compiler, Linux PipeWire test, two
+  CI-only x264 tests). Its GObject property probe, host/encoder check and
+  x264-absence check ran. The final native probe is checked in the PR's
+  Windows CI build, not by this VM run.
+- Browser check with the real production HTML/JavaScript and mocked Windows API
+  responses: DXGI whole-screen Show remains available, the limitation appears
+  once, WGC window sources retain Show, off hides controls, and the limitation
+  text is escaped. This used a static asset server, without headset API access.
+- `node --test app/test/*.test.js`: passed, three test files.
+- `node --test site/test/*.test.mjs`: passed, one test file.
+- The first full Linux run inside the sandbox failed (11 failures, 139 errors),
+  including loopback socket `PermissionError`. The successful full runs were
+  outside that socket restriction.
+- An initial guest test archive omitted `apk-catalog`, causing one import
+  error; the complete archive produced the 33-test passing Windows run.
+
+Raw local logs: `/tmp/frame-windows-{pc,app,site}-tests.log`,
+`/tmp/frame-windows-full-tests-unrestricted.log`,
+`/tmp/frame-windows-full-fixed-tests.log`, and
+`/tmp/frame-winvm-priority3/`. The committed artifacts above preserve the
+capture, Windows test and headset evidence independently of those local files.
+
+## Shared Frame session and cleanup
+
+Read-only checks first: SteamOS 0.5.6, BUILD_ID `20261015.6141207`, battery 99%,
+Not charging (another supply reports Full). The lock was free.
+
+Both attempts acquired `/tmp/frame-test.lock` atomically before any key or
+viewer changes, and removed only the lock acquired by this task. The first,
+35-second attempt failed because the test wrapper sent CRLF script input and
+left SSH stdin open. Production already sends script bytes and closes stdin;
+correcting the wrapper resolved both. Its key was removed and lock released.
+
+The successful session held the lock **03:09:36–03:10:05 UTC (29 seconds)**.
+It used a dedicated `pc-view-priority3` profile and port range 47960–47964,
+leaving existing viewers/profiles alone. The app's Windows `PCView` captured
+`display:65537`, 1280×800, Light preset (30 fps ceiling), and opened panel
+`valve.steam.desktopgame.2001396898`. The viewer reported H.264 software decode,
+218 received frames, 215 decoded/drawn before the snapshot (219 sent records).
+
+This mostly idle, roughly ten-second sample reported 19 fps and content delay
+p50/p95 51.6/75.2 ms. These are observations, not a performance-target pass.
+
+Cleanup stopped the helper and tunnel, closed the own viewer, removed its two
+possible profile paths and log, then removed the exact public-key line. The
+`authorized_keys` SHA-256 was identical before/after. A follow-up login from
+Windows with that key failed with exit 255. Separate checks found no task-owned
+viewer processes, the profile absent, and the shared lock released. Battery
+remained 99%; the sampled gamescope focus properties matched before/after.
+No reboot, global settings changes, game launch or Steam/SteamVR stop occurred.
+
+## Limits
+
+This verifies a Windows VM's desktop capture, Media Foundation encoding and
+real Frame viewer decode/rendering. It does not verify physical-PC hardware
+encoding, WGC or individual-window capture, mixed DPI, multiple displays,
+physical laser alignment/clicks, keyboard layouts, resize/minimise, busy-scene
+performance, bitrate/encoder restarts, or worn-headset comfort. No input was
+injected during the real Frame session. The installed app’s Tools navigation was not exercised; its streaming
+controller, tunnel and viewer were exercised directly. No independent review was performed.

+# Windows Wireless Adapter doctor verification, 24 October 2026
+
+PC-only implementation and verification. No Frame was contacted, before or
+after 13:00 UTC. No adapters or security settings were changed. This evidence
+does not establish a physical Steam wireless adapter fix or RF interference.
+
+## Windows VM
+
+An existing local Windows 11 VM (build 26200), Python 3.12.14 from the installed
+Frame Control bundle, ran the isolated suite from a task-specific Downloads
+folder:
+
+```powershell
+& 'C:\Users\frame\AppData\Local\Programs\Frame Control\resources\python\python.exe' -m unittest discover -s tests -p test_wireless.py -v
+```
+
+Result: **15 tests, OK, one skipped** (Node absent). This includes the real
+read-only PowerShell inventory and authenticated HTTP handler tests. The app's
+connector was never started. Existing test SSH credentials were used only for
+the Windows VM; no credentials were copied into the repository.
+
+- [Exact test output](windows-wireless-tests-2026-10-24.txt).
+- [Sanitized live inventory](windows-wireless-summary-2026-10-24.json): two
+  virtual-machine network devices, with PnP/presence/adapter/route sources
+  available. WLAN unavailable; channels/bands remained null. All PnP IDs,
+  device names and interface names were removed from this artifact.
+- The guest clock was approximately seven hours ahead of the host. `observedAt`
+  is retained as returned by Windows, not used to establish test timing.
+
+The first probe used a list of requested default prefixes. A missing IPv6
+route caused PowerShell to throw away available IPv4 data. The final query
+filters `Get-NetRoute` results instead, and the rerun above confirms routes
+are available. No network configuration was changed to make the query work.
+
+## Browser UI and local tests
+
+Production `ui/index.html` ran against a loopback-only synthetic API fixture,
+with no connector and no headset transport. Opening/revisiting the tool caused
+no wireless query; an explicit click rendered two distinct Wi-Fi Direct PnP
+instances and a 2.4 GHz PC interface while the headset state was offline.
+Unknown virtual-adapter channels, non-present/disabled status, and unconfirmed
+interference remained visible. Checked at 1280 and 640 CSS pixels without
+horizontal overflow.
+
+![Production browser UI with explicitly labelled synthetic Windows readings](windows-wireless-synthetic-2026-10-24.png)
+
+The screenshot uses synthetic readings, not the VM's two Ethernet interfaces.
+The yellow synthetic-data label was added by the browser fixture for this
+capture; it is not product UI.
+
+Local commands:
+
+```sh
+python3 -m unittest discover -s tests -p 'test_wireless.py' -v
+node tests/wireless.cjs
+python3 -m unittest discover -s tests -v
+python3 -m py_compile ui/*.py
+node --check /tmp/wireless-index-scripts.js
+```
+
+The targeted suite passed 15 tests with the live Windows-only test skipped;
+the direct Node run passed all four UI tests. The complete server suite passed
+1,423 tests with 16 skips before the additional missing-metadata test; a final
+complete run and Windows CI results are recorded in the PR. The syntax check
+used inline scripts extracted from the production HTML.
+
+## What remains unverified
+
+No physical Steam dongle, Razer headset, live Wi-Fi Direct session, channel
+reading from real wireless hardware, dropout reproduction or recovery action.
+The English netsh parser is fixture-tested; localised or denied readings remain
+unknown. Windows CI validates query execution on hosted virtual hardware.
+There is no adapter disable action because the available evidence cannot
+reliably identify a safe extra instance.

+# 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.

+## Desktop low-battery alert without a session
+
+In the desktop app, open **Tools → Family & comfort** and check **Alert on this
+computer at 15% or less**. This separate option does not start a session, install
+a worker or change the headset. It starts off whenever the page opens and turns
+off when you switch headsets. The choice is only for the current open page.
+
+It consumes the battery parser already used by normal status refreshes (also
+shared by the read-only power sampler). It adds no SSH calls, timers, sensor
+reads, third-party push or heat thresholds. Normal automatic status refreshes
+pause while the page is hidden, so this is **not a background or safety monitor**.
+Keep the app visible and connected. Use **Enable / test notifications** to check
+system delivery; operating-system settings may block notifications.
+
+Two fresh readings, at least 20 seconds and at most 90 seconds apart, must show
+15% or less, driver state `Discharging`, and signed battery power below −0.5 W.
+This avoids alerting on plugged-in idle readings, which can report discharging.
+Missing, invalid, stale or interrupted readings break confirmation. Disconnect,
+a failed status request, hiding the page or toggling the option also breaks
+confirmation. Unknown readings never mean zero charge.
+
+An alert appears in the page and requests a native desktop notification once
+per low-charge episode. Two readings at 20% or more rearm it, and at least ten
+minutes must pass between alerts (including across headset switches). A single
+recovery spike cannot rearm it. Toggling off/on does not clear the episode latch.
+Notification failure stays visible in the page and does not retry on every
+refresh. While an active family session has battery alerts enabled, that session
+handles battery alerts instead. Multiple app windows have independent state;
+this does not coordinate notifications between computers or windows.
+
+A read-only check on 2026-10-24, build **20261015.6141207**, received two samples
+at 99%, `Not charging`, approximately −0.06 W and 24 °C. No low-battery condition
+was induced, no notification was sent to the real headset, and no headset state
+was changed. The sampler's local and remote smoke-lock checks allowed the run;
+no lock was acquired or removed. Deterministic tests exercise low charge,
+recovery, missing readings, idle drain, timing and notification denial. See
+[recorded evidence](evidence/desktop-battery-comfort-2026-10-24.json). Native OS
+notification display, worn use and macOS/Windows packaging were not verified.

 ## Sessions
 
 Set a limit of 1–240 minutes, optional break and check-in intervals, then
