 ## Unreleased
 
+- 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

+## Open the app
+
+- **macOS:** open the `.dmg`, drag **Frame Control** to **Applications**, then
+  open it from Applications. For the unsigned-app 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.
-
-   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).
+   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).

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/2d6327017519d23b96af35865dc997fcb544fb40/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

-# Frame Control for Android phones
-
-The native Android companion lives in `android/`. It requires Android 10 or
-later and a Steam Frame with Developer Mode and SSH enabled. This is a new
-implementation, separate from the headset's `frame/android` Lepton tools.
-
-## Pair and sync
-
-1. Enter the headset address, SSH port and username (normally `steamos`).
-2. Choose **Pair headset**, compare the displayed SSH fingerprint with the
-   headset's identity, and accept it. Enter the Developer Mode password once.
-   The app installs this phone's SSH public key and verifies key login before
-   storing the pairing. The private key stays in Android Keystore; the
-   password is not saved. A changed headset host key is refused.
-3. Choose **Start syncing** and allow notifications. The persistent notification
-   shows the active connected-device session and offers **Stop syncing**.
-4. Take a new screenshot. Its original downloads into Frame Control. **Save
-   screenshots to Gallery** is enabled by default and adds it to
-   `Pictures/Frame Control`. Android 10+ lets an app create its own Gallery
-   items without broad photo-reading permission.
-
-The first successful listing establishes a history baseline. Existing screenshots
-are not imported automatically. The app waits for two equal size/time listings,
-checks the original's byte count and image decode, and saves it atomically.
-Identity includes the paired headset, Steam account, game and filename.
-
-Turning Gallery off keeps automatic downloads inside Frame Control. Pending
-exports become app-only; enabling it again does not export those earlier items.
-Previously saved Gallery items stay there. Original files remain available from
-**Open / share original** when disconnected. The app keeps each headset's
-library separately.
-
-Gallery export uses a deterministic app-owned MediaStore row. A pending row is
-rewritten after interruption, and a completed row is recognized before inserting
-another. A failed export leaves the app original available for retry. Preferences
-and the final Gallery commit are serialized so a disabled setting is respected.
-
-**Headset controls** opens the shared Frame Control web interface through a
-loopback-only SSH tunnel. The server has a fresh session key and listens only on
-the headset's loopback interface. The tunnel and server end with the phone's
-SSH session. This initial Android shell does not implement all iPhone-specific
-web bridges; native screenshot originals use the downloads screen.
-
-## Background behavior and release boundary
-
-Sync is an explicit, user-started Android `connectedDevice` foreground service.
-It can continue after leaving the app while its notification is present and
-reconnects when the headset returns. It is not a Firebase push receiver.
-Android battery-saving/Doze, loss of network, force-stop or process termination
-can delay or end the session. The app does not request battery-optimization
-exemption, use unrelated background modes, or restart itself after force-stop.
-Restart sync from the app if the session ends.
-
-The full cross-platform request still requires actual locked-phone background
-proof. iOS APNs delivery is a separate unimplemented dependency. An emulator
-test is not evidence that either physical platform meets that requirement.
-Do not publish this as a verified always-on screenshot feature.
-
-## Build and verify
-
-Use JDK 17 and an Android SDK containing platform 36/build-tools 36.0.0:
-
-```sh
-export JAVA_HOME=/path/to/jdk17
-export ANDROID_HOME=/path/to/android-sdk
-./android/gradlew -p android assembleDebug testDebugUnitTest lintDebug
-```
-
-The Gradle wrapper pins version 9.4.1 and its distribution checksum. The build
-generates the same reproducible headset bundle as iOS, including the existing
-SHA-256-checked KDE Connect package fetch. Generated assets and build outputs
-are ignored. No signing key, headset password or machine-specific SDK path is
-committed. `assembleDebug` produces `android/app/build/outputs/apk/debug/app-debug.apk`.
-It uses a development signing identity, not a configured Play release key.
-
-`assembleDebugAndroidTest` builds instrumentation for real MediaStore round-trip,
-retry recovery and app-only behavior. Optional real-headset hooks exist only in
-the separate test APK (`ScreenshotDeviceTest`), not in the product app. They
-provision a public test key and permit original/Gallery hash readback without
-adding a product authentication bypass. Remove the temporary headset key and
-fixtures after live tests.
-
-No Play app creation, store upload, invitation or public release is part of a
-debug build. Preserve a dedicated release signing identity and verify physical
-devices before a production release.

+confirmed full Plasma Desktop Mode on the same build: the Plasma session target
+was active and the Game Mode target inactive. Desktop Mode also ran gamescope
+for `steamvr-plasma.service`, so the old process check incorrectly reported
+Game Mode. SteamOS's `steamosctl switch-to-game-mode` restored Game Mode and
+reversed the target states; battery stayed at 99%, and the rollback timer and
+shared lock were cleaned up. After #143 passed CI, the corrected code was

+the button. Game Mode became active and a second call made no switch. Battery
+remained at 99%; the timer and lock were removed. That test used the production
+CLI rather than clicking the desktop button.

+# 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).

-# Android phone screenshot sync evidence — 2026-10-24
-
-Work: [#108](https://github.com/saphid/frame-control/issues/108). The user
-authorized a new Android companion after the earlier APK could not be located.
-This is a development build, not a production or Play release.
-
-## Implemented
-
-Native Android 10+ companion in `android/`, with pinned SSH transport and a
-non-exportable Android Keystore phone key. Pairing checks the host fingerprint
-before accepting a password and verifies key login before saving the pairing.
-The shared headset server runs through a session-bound loopback tunnel.
-
-All retained libraries receive Gallery opt-out, including previously paired
-headsets. Paging keeps older offline originals reachable beyond the first 100.
-A failed image or Gallery export retries independently without starving later
-downloads; local persistence errors still halt immediately.
-
-The user starts a connected-device foreground service with an ongoing Stop
-notification. New screenshot originals download automatically. Gallery is ON
-by default; turning it off latches pending and newly discovered items to
-app-only, including across relaunch and later re-enabling. Historical captures
-are baselined instead of imported. Receipts, original files, and MediaStore
-recovery support interrupted downloads/exports without duplicate Gallery rows.
-
-See [usage and background limits](../android-phone.md).

-  receipts, corrupt state, unsafe paths, late cancellation callbacks, per-item
-  failure isolation and fatal persistence errors.
-- API 36 arm64 emulator MediaStore tests passed: original byte round-trip,
-  app-only across relaunch, interrupted pending row recovery and retry dedup.
-  The final rebuilt APK passed **five selected native checks, no skips**:
-  three MediaStore/multiple-library cases plus the actual headset fixture
-  Gallery hash (`/tmp/frame-108-android-final-device-r4.log`, four tests), then

-## Actual headset → Android emulator → Gallery
-
-Target: task-owned headless API 36 emulator `emulator-5588`, with the actual
-Steam Frame reached over SSH. Initial baseline contained nine historical
-captures and imported none. An emulator-generated public test key was installed
-temporarily through the existing trusted SSH alias; no password was exposed.
-The unauthenticated native host-key probe matched the trusted headset key.
-
-Synthetic fixture IDs use a separate test account/game namespace; this verifies
-new-file delivery from the real headset, not the hardware capture shortcut.

-| App-only independent readback | One selected native test passed: correct app original and no matching Gallery row |
-| Re-enable and restart | App-only receipt and absent Gallery row preserved; first image remains saved, no duplicate |
-| Open/share original | Native chooser opened for the app-only original and was canceled; nothing sent |
-| Final r5 APK, Gallery ON while Home | Third new fixture `999999999990/108/20261024101413_1.png` reached Gallery in 5.288 seconds (one synthetic trial); same source/app/Gallery hash as the first fixture, one matching row |

-a library-switch cache identity issue: matching receipt fields could retain a
-Share action bound to the previous headset. The refresh signature now includes
-the absolute original path, including the headset library root.
-
-The final r6 build (`assembleDebug assembleDebugAndroidTest lintDebug`) exited
-zero: `/tmp/frame-108-android-build-r6.log`. A new native regression launches
-the real activity, switches between two libraries with matching receipt fields
-but different original bytes, and verifies that Share now selects B’s bytes.
-The chooser is intercepted; nothing is sent externally. This regression and
-the three existing MediaStore/multiple-library cases passed together: **four
-selected tests, no skips**, `/tmp/frame-108-android-final-device-r6.log`. Core
-code is unchanged from the 34 independently passing JVM tests. The r6 change
-does not alter the r5 transfer/storage path exercised against the real headset.

-**No actionable findings** in the frozen 25-file executable target (`android/`
-and `.github/workflows/android.yml`), with the remaining share-binding finding
-resolved. All executable fingerprints stayed unchanged during review. Report:
-`/tmp/frame-108-android-review-sol-r3.md`. The review inspected the passing r6
-native/build logs and unchanged core covered by round 2’s independent 34-test
-run; it did not claim new device runs or release validation.

-Cleanup removed the one exact temporary public key and all three exact synthetic
-headset fixture paths, verified absent. Other authorized keys and real captures
-were preserved. Readback: `/tmp/frame-108-android-cleanup.json`. The task-owned
-`emulator-5588` was shut down after the live tests, then restarted only for

+# 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.

+# 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`.
+- `/run/user/1000/pipewire-0` and `/run/user/1000/wayland-0` did not exist.
+  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.
+- `dpkg-query` found no `xdg-desktop-portal*` or `pipewire*` packages.
+  `libgstreamer1.0-0:amd64` was installed at `1.24.2-1ubuntu0.1`, but
+  `gstreamer1.0-tools` was uninstalled. `gst-launch-1.0` and `gst-inspect-1.0`
+  were absent from PATH. Xvfb was installed, but supplies no portal by itself.
+- `pkg-config --modversion` failed for `gstreamer-1.0`,
+  `gstreamer-app-1.0`, `gstreamer-video-1.0` and `libpipewire-0.3`.
+  `gio-unix-2.0` reported `2.80.0`.
+- `desktop/bundle/pc-host.so` did not exist.
+  `python3 desktop/build.py --with-x264 --out /tmp/frame-linux-pc-feasibility`
+  exited **1** before compilation: required GStreamer pkg-config modules were
+  missing. No native build or encoder runtime success is claimed.
+
+Reproduce the non-activating portal checks in the intended desktop user's
+session, using that session's actual runtime directory and bus:
+
+```sh
+gdbus call --session --dest org.freedesktop.DBus \
+  --object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ListNames
+gdbus call --session --dest org.freedesktop.DBus \
+  --object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ListActivatableNames
+pkg-config --modversion gstreamer-1.0 gstreamer-app-1.0 gstreamer-video-1.0 gio-unix-2.0
+```
+
+## 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 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.

+# 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` |
+|---|---|---|
+| FindOverlay | 0, Success | 0, Success |
+| Rendering process | `gamescope-wl` | `gamescope-wl` |
+| Width | 0; 2.6700000763 m | 0; 2.6670000553 m |
+| Curvature | 0; 0 | 0; 0 |
+| Transform type | 0; 5, DashboardTab | 0; 5, DashboardTab |
+| Absolute transform | 18, WrongTransformType | 18, WrongTransformType |
+| Tracked-device-relative transform | 18, WrongTransformType | 18, WrongTransformType |
+| Coordinate transform, center, standing origin | 0; identity matrix | 0; scaled/translated matrix |
+| Coordinate transform, center, seated origin | 23, RequestFailed | 23, RequestFailed |
+| Coordinate transform, center, raw origin | 23, RequestFailed | 23, RequestFailed |
+
+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

+- `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.

-# iOS foreground screenshot downloads — 2026-10-24
-
-This is implementation and proof for the foreground iOS portion of
-[#108](https://github.com/saphid/frame-control/issues/108). It is not the full
-requested background/cross-platform feature and is not released.
-
-## Source and merge
-
-Dedicated worktree: `/Users/saphid/.t3/worktrees/steam-frame/feat-phone-screenshot-autosync-108`.
-Branch: `feat/phone-screenshot-autosync-108`.
-
-First merged fetched main
-[1d4c57d6](https://github.com/saphid/frame-control/commit/1d4c57d6)
-into the existing Mac-space parent
-[3fdc6c46](https://github.com/saphid/frame-control/commit/3fdc6c46).
-Merge commit: [52772323](https://github.com/saphid/frame-control/commit/52772323).
-The dirty primary checkout was left untouched. Review found and fixed the PC
-helper's missing public route for the extracted `mac-stream.js` dependency.
-Independent merge re-review ran 45 tests successfully, one skipped, and found
-no remaining actionable findings in its seven-file target.
-
-## Implemented behavior
-
-- Native polling every four seconds while active, independent of the visible web tab.
-- First successful listing becomes the durable baseline; only new captures queue.
-- Two equal metadata observations, exact byte count and complete ImageIO decode
-  precede an atomic original write outside purgeable caches.
-- Receipts and originals distinguish pinned headset identity, Steam account,
-  app ID and filename. Reconnect/relaunch resumes pending work.
-- Photos is enabled by default. Add-only permission is requested in foreground.
-  Denied/failed exports keep originals; app-only captures never automatically
-  export after re-enabling the setting.
-- Native downloads sheet exposes retained files through ShareLink, including
-  during connection failure/relaunch. Ambiguous interrupted Photos commits need
-  explicit recovery rather than risking an automatic duplicate.
-- Backgrounding stops polling; no unrelated background mode is used.
-
-## Automated verification
-
-Normal signed Simulator build and full native test suite: **20 tests passed,
-zero failures**, including eight screenshot tests. Result bundle:
-`/tmp/frame-108-ios-all-r3.xcresult`; log: `/tmp/frame-108-ios-all-r3.log`.
-Both command exit status and xcresult test count were checked. Private
-DerivedData cleanup completed. Test target was the independently created
-Simulator `F250F91E-2E7D-4833-B029-A275F11FDC7D` on iOS 26.5.
-
-Screenshot tests cover baseline/stability, truncated data, restart dedup,
-Photos failure/retry, changes during download/consent, cancellation,
-account/app identity, corrupt-ledger failure, uncertain export handling,
-late success and failure across journal replacement, default preference and
-offline app-only originals. Download/export dependencies in these tests are
-injected; the live test below exercises actual transport and PhotoKit.
-
-Python iOS packaging/Foundation contracts: 5 passed. Page scripts: 5 passed.
-`swiftc -typecheck` for the journal and scoped `git diff --check` passed.
-
-## Actual headset → Simulator → Photos proof
-
-Ran the production signed app against the real headset over its pinned SSH
-connection and the actual deployed `/api/shots` and `/api/shots/image` endpoints.
-Created two temporary valid PNGs under a unique synthetic Steam account/app
-directory after the app had baselined the existing nine screenshots.
-
-| Check | Observed result |
-|---|---|
-| Default Photos ON | Original downloaded and receipt marked `saved`; Photos contained one byte-identical original |
-| Source / app copy / Photos SHA-256 | `a36eb2d497e6ecce17c767189a70b3b7e732a22309d2421cdc715cf13a7668ac` |
-| Photos OFF | Second original downloaded with `appOnly`; no matching Photos original |
-| Re-enable + relaunch | Second receipt stayed `appOnly`; first still had exactly one Photos original |
-
-Machine readback: `/tmp/frame-108-live-proof.json`. Photos readback hashed files
-in this dedicated Simulator's own Media/DCIM directory, independently of the
-app receipt. No personal phone Photos database was accessed. This is a
-synthetic capture-file test, not proof of the headset screenshot-button path,
-capture latency, physical-device behavior, or background delivery.
-
-The OFF preference was applied through Simulator defaults on restart, not a
-UI tap. The production setting setter and persisted opt-out were exercised in
-the native tests. Astra inspected the real native sheet in both states and
-found no major clipping, overlap or actionable visual defect.
-
-![Photos enabled and app-only setting](phone-screenshot-sync-2026-10-24/settings-proof.png)
-
-An initial unsigned test build could not retain a stable Keychain identity;
-the real transport test used normal Simulator signing. App launches with a
-console attached were kept alive for the live checks.
-
-## Review provenance
-
-Preferred Opus routes failed before work with API rate limits. Implementation
-used the current GPT-6.1 Sol session; reviews are disclosed as fresh same-model
-checks, not different-model evidence.
-
-Provider `codex`, model `gpt-6.1-sol`, high, completed:
-
-- r1: `node:delegated-task:command%3Amcp%3Ac03980f6-1e71-4cc4-af1a-1d0961b9aaad%3Adelegate-task%3Aframe-108-ios-sync-review-20261024-r1`.
-  Found stale export callback persistence and missing offline access. Both fixed.
-- r2: `node:delegated-task:command%3Amcp%3Ac03980f6-1e71-4cc4-af1a-1d0961b9aaad%3Adelegate-task%3Aframe-108-ios-sync-review-20261024-r2`.
-  No actionable findings in the complete executable diff against `52772323`
-  plus the four new Swift files. Report: `/tmp/frame-108-ios-sync-review-r2.md`.
-
-Visual inspection used provider `codex`, `gpt-6-astra`, completed task
-`frame-108-downloads-proof-inspection-20261024-r3`; report:
-`/tmp/frame-108-downloads-proof-inspection.md`.
-
-## Remaining release requirements
-
-- Actual APNs delivery, notification extension/shared state, persistent headset
-  event source and authenticated delivery service are still unimplemented.
-  Main-app push capability is not configured; no usable provider credential
-  location was found in the bounded checks. Existing App Store Connect signing
-  access is not an APNs provider key.
-- Physical locked/background iPhone download and Photos export remain unproven.
-- A new native Android companion was subsequently authorized and implemented.

+# 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. |

+# 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.

+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.

+## 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.

-upload environment to use the replacement. Revocation does not remove an
-already uploaded TestFlight build from testers' phones.
-
-### Add testers
-
-**Internal:** add an existing App Store Connect user with an eligible role to
-an internal testing group, and add the build to that group (or enable automatic
-distribution). New account users must first accept their account invitation.
-Internal testing grants App Store Connect access; use external testing for
-people who only need to try the app.
-
-**External:** create an external testing group, complete Beta App Information
-and review contact details, add a build and its **What to Test** notes, then
-submit it for TestFlight App Review when required. Use
-<https://framecontrol.fun/privacy/> for the privacy policy and
-<https://framecontrol.fun/feedback/> for feedback. Review notes must explain
-that the app requires a Steam Frame with Developer Mode enabled and a user
-password; do not provide your own headset credentials to reviewers. Apple may
-need a way to evaluate features that require the hardware.
-
-After Apple approves the build for external testing, enable the group's public
-link and choose a tester limit. Share that link to let testers join without an
-App Store Connect account. Creating a group alone does not make a build public.
-Do not describe the link as ready until the approved build is in the group and

+# Linux Wireless Adapter doctor
+
+![Linux PC doctor before any checks run, with explicit hardware selection and read-only limits](img/linux-wireless-doctor.png)
+
+On the **Linux PC**, open **Settings → Linux Wireless Adapter doctor**, or
+**Devices & connection → Linux Wireless Adapter doctor**. It works without a
+connected headset. Choose **Read PC device inventory**, select the intended
+USB device or wireless interface, then **Check selected device**. Nothing runs
+until requested. Re-read the inventory after reconnecting a device.
+
+From a source checkout, the same collector is available without starting the
+app or its headset connection workers:
+
+```sh
+python3 ui/frame_wireless_doctor.py
+python3 ui/frame_wireless_doctor.py --device net:wlan0
+python3 ui/frame_wireless_doctor.py --device usb:1-2 --json > adapter-report.json
+```
+
+Use a selector actually listed on your PC. No device is selected automatically.
+All USB devices are included, including hubs and devices without a network
+interface. A product label, observed VID/PID, or a single available interface
+**does not identify Valve's adapter**. There is no trusted adapter ID table in
+this feature. Compare inventory before and after reconnecting the intended
+adapter when safe. For a USB device exposing multiple wireless interfaces,
+select the specific interface for radio/manager evidence.
+
+## Evidence and limits
+
+- **Presence and binding:** `/sys/bus/usb/devices` and `/sys/class/net` correlate
+  USB ancestry, wireless interfaces, driver links and module links. An absent
+  interface does not establish which driver should be installed. A missing
+  module link may mean a built-in driver. A bound driver does not prove Steam
+  streaming support.
+- **Permissions and udev:** `udevadm info --query=property` supplies a small
+  allowlist of driver, ID and tag fields. If available, the report includes USB
+  node mode, owner/group IDs and the current user's read/write access. Direct
+  USB access is not necessarily required by kernel networking; a restrictive
+  node alone is not diagnosed as the cause. No udev rules are installed or run.
+- **Radio blocks:** read-only WLAN rfkill sysfs entries are matched to the
+  selected interface's PHY name. An unrelated block cannot establish that
+  this adapter is blocked. Unavailable or unmatched entries remain unknown.
+- **Channel/band:** `iw dev IFACE info` provides the current channel and
+  frequency where reported; `iw phy PHY info` supplies enabled frequencies.
+  An idle interface may have no current channel. These observations do not
+  establish the channel used by a Steam streaming session, supported regions,
+  or the correct regulatory setting.
+- **Network managers:** visible `/proc/*/comm` process names show
+  NetworkManager, iwd and wpa_supplicant. `nmcli` reads only the selected
+  interface's general state, managed flag and driver. NetworkManager can use
+  iwd or wpa_supplicant as its backend, so coexistence is not itself a conflict.
+  If both backends are visible, the report suggests checking who owns this
+  exact interface. It does not claim a confirmed conflict or stop services.
+  Restricted process visibility and unverified backend ownership are explicit.
+
+Every command uses fixed read-only arguments, no shell, closed stdin and a
+three-second timeout. Optional tools are not installed automatically. Missing
+tools, denied reads, disappearing devices, and restricted VM/container hardware
+visibility remain unknown. A successful report is a snapshot, not a hardware
+health certificate. CLI exit 0 means collection is supported, not that the
+adapter works; unsupported platforms/headset-local mode return 2, as does an
+invalid/stale selector. JSON has schema version 1.
+
+The doctor never uses SSH, scans nearby Wi-Fi networks, opens a connection to
+the Frame, escalates privileges, loads drivers, changes security settings,
+changes channels, unblocks radios, changes network settings, or restarts
+services. Run it as your ordinary user, never with sudo. The app hides the
+entry on macOS, Windows and phone sessions; its API refuses collection in
+headset-local (`FRAME_LOCAL=1`) mode. The source CLI is intended only for the PC.
+
+Reports stay local unless you explicitly save, copy or share them. Exported
+fields include observed USB IDs/product labels, interface names, driver names
+and permission metadata. USB serials, Wi-Fi names, MAC/IP address fields,
+credentials, process arguments and raw command output are not exported. Review
+the report before posting it: hardware labels and local paths can identify
+parts of your setup.
+
+## Motivation and shipped comparison
+
+[The 23 October 2026 complaint](https://x.com/ExpressGinga81/status/2113457683143741720)
+says the Wi-Fi dongle does not work on Ubuntu/Kubuntu 26.04 while SteamVR works
+under Wayland. It supplies **no adapter VID/PID, driver, logs or established
+cause**. This feature helps gather that missing evidence; it does not claim to
+fix that complaint or certify Ubuntu/Kubuntu 26.04 support.
+
+Shipped **v0.4.18** has local network/gateway discovery in `frame_network.py`
+and headset connection management, but no local USB/driver/rfkill adapter
+report or adapter diagnostic UI. The existing `frame-doctor.sh` diagnoses the
+headset through SSH and is a different tool. This doctor never calls it.
+General SteamOS 3.9.5 / Frame OS 0.5.6 compatibility and OS backend transition
+notes are covered separately in
+[`docs/steamos-2026-10-compat.md`](https://github.com/saphid/frame-control/blob/9c7110c1f48d160b0fb3c3b9f658d4937bd2032d/docs/steamos-2026-10-compat.md)
+([PR #164](https://github.com/saphid/frame-control/pull/164)). Existing PC
+route/SSID diagnostics use NetworkManager's `nmcli` with an `iwgetid` SSID
+fallback, independently of whether NetworkManager uses wpa_supplicant (SteamOS
+3.9.5 new installs) or iwd (upgrades). This doctor reads actual PC evidence and
+does not infer a conflict, hardware identity or fix from those OS defaults.
+There is no adapter-specific device observation in that compatibility work.
+
+## Verification
+
+```sh
+python3 -m unittest discover -s tests -p test_wireless_doctor.py -v
+python3 -m unittest discover -s tests
+```
+
+Tests use an explicitly synthetic USB `1234:5678`, sysfs trees, command replies
+and loopback HTTP. They cover an unbound USB device, module binding, multiple
+interfaces, PHY-matched and unrelated rfkill entries, channel parsing, manager
+coexistence, missing/denied commands, stale/injected selectors, export field
+filtering, authentication and refusal to probe in headset-local mode. The
+HTTP tests instantiate the handler without starting headset workers.
+
+Linux host collection was exercised on kernel `6.8.0-139-generic`: an existing
+PC interface was visible with its `iwlwifi` binding and unblocked PHY; `iw` and
+`nmcli` were absent and reported as unavailable. This is **not a physical Steam
+Frame Wireless Adapter test**, an Ubuntu/Kubuntu 26.04 test, or a headset test.
+No Frame access is part of this work.

-
-- **Connecting.** Look at the Mac and a **Connect** button floats above it.
-  There's also a Control Center route. The Mac's own screen goes dark
-  (**documented**/**reported**).
-- **Placement.** The display appears where you were looking, near the Mac,
-  at a large-monitor size. After that it stays put in the room: moving the
-  laptop doesn't move it. Holding the Digital Crown recenters everything
-  (**documented**).
-- **Handling.**
-  - A **window bar** under the display moves it, with pinch and drag, and
-    also moves it nearer or farther.
-  - Its bottom **corners** resize it.
-  - **Close** sits to the left of the bar (**documented**).
-- **Modes.** Standard (16:9), Wide (21:9) and Ultrawide (32:9, about 10K
-  pixels across). All are curved since visionOS 2.2 (**documented**).
-- **Input.**
-  - The Mac's keyboard and trackpad drive it.
-  - The pointer moves to whichever window you look at (Universal Control).
-  - Mac audio plays in the headset (**documented**).
-- **What it can't do.** You can't pull a single Mac window out of the
-  virtual display (**reported**, several sources). That's our
-  differentiator.
-
-## What the Frame allows
-
-- **Moving SteamVR's panels from our own process: no** (**verified**
-  2026-09-28). `FindOverlay("valve.steam.desktopgame.<id>")` works from a
-  separate OpenVR app, but `SetOverlayTransformAbsolute` returns 12
-  (`VROverlayError_PermissionDenied`). The panel reported transform type 5
-  (dashboard tab). Only SteamVR's dashboard, which runs in `vrwebhelper`,
-  moves them, through its privileged `VRHTML.VROverlay`, and it has no
-  DevTools port. See `/tmp/fmv-space/ovprobe.py` for the probe, which stays
-  outside the repo.
-- **WebXR in Chromium XR: yes** (**verified** 2026-09-26/27,
-  [webxr-chromium.md](webxr-chromium.md)).
-  - `immersive-vr` runs at 72–75 fps.
-  - Passthrough shows wherever the page leaves pixels transparent.
-  - Controllers are `tracked-pointer`s with `xr-standard` gamepads, and
-    squeeze events arrive.
-  - Hands are tracked with 25 joints.
-- **Our own OpenVR overlays: possible, but most work.** We would own their
-  transforms and get laser input as mouse events for free. But the Frame
-  would need native H.264 decoding and texture upload.
-
-## Decision: a WebXR "Mac space" page first
-
-The WebXR page (`ui/mac-space.html`) holds everything, with passthrough
-behind it:
-
-- **The desktop.** A large curved panel shows the Mac's main display,
-  placed above the laptop. The first time, you place it yourself; after
-  that it's remembered in the room.
-- **Windows.** Each separated window gets its own panel.
-- **Grabbing.** A bar under each panel moves it (squeeze, or pinch with a
-  hand). Its corners resize it, and there's a close button to the bar's
-  left, as on Vision Pro.
-- **Pulling a window out.** Grab a window's title bar on the desktop panel
-  and drag it off the edge. The page starts a `separate:<window id>`
-  stream, the window moves to its own display on the Mac, and its new
-  panel follows your hand until you let go. Dropping a panel back onto the
-  desktop panel stops the stream, and the window goes back.
-- **Input.** The laser and trigger click and drag, the thumbstick scrolls,
-  and the Mac's keyboard types, as today.
-
-Trade-offs:
-
-- It's the headset's active app while you use it. Other VR apps pause, but
-  SteamVR's own overlays still draw on top.
-- Text sharpness depends on how the page renders. WebXR quad layers (the
-  `layers` feature) would let SteamVR's compositor sample each panel
-  directly, so they're worth checking first.
-
-## Building blocks
-
-- **One module for the protocol.** `ui/mac-stream.js` holds the stream
-  protocol (connect, clock sync, decoding, acks and reports, input), shared
-  by `mac-view.html` (the 2D panel) and `mac-space.html`.
-- **A space key from the agent.** Frame Control gets a ticket with
-  `src=space`, and the page trades it once for a **space key**, kept in
-  memory. That key lists the windows and displays (with their positions,
-  for picking the one under the pointer) and opens streams for any of
-  them. Stop All revokes it.
-- **Anchoring.**
-  - v1: manual placement, remembered in the room (to be checked: whether
-    `local-floor` stays put between sessions on the Frame).
-  - v2: the Mac shows a marker on its screen for a moment, and the headset
-    finds it. That needs camera access, which is **unknown** on the Frame:
-    the passthrough cameras are monochrome, and `IVRTrackedCamera` hasn't
-    been tried.
-
-## Open questions
-
-- Frame rate with several software-decoded streams at once.
-- Whether `local-floor` placements survive restarts.
-- Whether WebXR quad layers work in Chromium XR's OpenXR path.
-- Whether Chromium grants `requestSession` without a click in the page
-  (needed for a one-click "Open Mac space").

+# Headset view in OBS
+
+Frame Control can send SteamVR's headset mirror and the Frame's output audio to
+OBS on a Windows, Linux or macOS computer. The helper uses the same `/dev/video99` video
+source and default-output monitor as **Capture & Live → Record**. It sends a
+local MPEG-TS stream; no port is opened to the LAN or internet.
+
+1. Connect to the Frame and start SteamVR. OBS runs on the computer; the Frame
+   already has `ffmpeg`.
+2. In the **Frame Control desktop app**, open **Capture & Live** and click
+   **Start OBS source**. Keep Frame Control open; **Stop OBS source**, switching
+   headsets, or quitting the app closes its SSH stream. It uses the selected
+   headset and the app's bundled helper.
+3. In OBS, add a **Media Source**, clear **Local File**, set **Input** to
+   `udp://127.0.0.1:15099`, and set **Input Format** to `mpegts`. The source
+   carries video and AAC audio. Use OBS's audio mixer to choose monitoring and
+   recording levels.
+
+From a source checkout, you can instead install `python3` on the computer and
+run:
+
+   ```sh
+   python3 scripts/obs-headset-source.py
+   ```
+
+Ctrl+C stops the checkout helper. The app closes a control pipe when you click
+Stop or quit; the helper then closes its SSH child, including on Windows. On
+Windows, install Python 3 and OpenSSH Client if Frame Control cannot find them.
+The Windows app Start/Stop path still needs a physical Windows/Frame test.
+
+To share the OBS view in a call, see the short
+[Discord setup guide](streaming-to-discord.md).
+
+`--height 1080 --fps 60` increases quality and Frame CPU use. The default is
+720p30. `--port 15100` selects another loopback port; use the same port in
+OBS. If the Frame's PulseAudio monitor cannot be read, the helper exits with
+an error. Use `--no-audio` only when a silent view is useful. To inspect the
+stream without OBS, run `ffprobe -v error -show_streams
+udp://127.0.0.1:15099` in a second terminal while the helper is running.
+
+This is the composited, undistorted one-eye **SteamVR mirror**, not a raw
+passthrough camera feed. The mirror may be blank when the headset is idle or
+unworn. Whether active passthrough pixels appear in it is still unverified.
+The helper does not send a microphone. It is designed for one local OBS
+receiver. **Verified 2026-10-25:** the helper bundled in the Linux AppImage
+sent a real Frame stream to OBS 30's Media Source. OBS recorded 37.6 seconds
+with H.264 video and AAC audio; a brief 440 Hz tone played to the Frame's
+default output was present in the saved audio. The headset was in standby, so
+the video showed the standby mirror. Nobody listened to OBS's monitoring output,

+raw measurements. The HTML also embeds those measurements; review it before
+sharing. No automatic browser launch occurs.
+
+HTML sessions are limited to `count × interval <= 600` seconds, with a 30-second
+transport allowance and at most twelve seconds of local child/pipe cleanup. The default
+12 samples at five-second intervals take about 55 seconds. Existing output files
+are never overwritten; choose a new filename for each run. `--html` cannot be
+combined with `--csv`. The desktop flow below uses the same sampler and renderer.
+
+Stop, timeout, SSH failure or a smoke-test lock marks the report incomplete;
+earlier received samples remain downloadable. Exit status is 75 for incomplete
+reports, 0 for completion. A connection that cannot start may instead return 1
+without an HTML file. Empty reports clearly show zero samples, not a successful
+measurement. If saving the file fails, received JSON is printed on stdout as a
+recovery path. Do not treat a partial report as a full baseline.
+
+Stopping terminates only this command's local SSH child. It sends no remote
+process-control command. The bounded remote Python reader exits when it next
+writes to the closed connection (normally at the next sample, up to one interval
+later); it can still read sensors before discovering the disconnect. Stop is
+not an immediate headset-side cancellation guarantee. The reader still checks
+the smoke-test lock before every sample. No lock is acquired or removed by this
+flow, and no power, thermal, service, password or security controls are exposed.
+
+## Desktop Tools → Power & heat report
+
+In the packaged desktop app, connect to an already paired Frame, open **Tools →
+Power & heat report**, choose **1 minute** (12 samples) or **5 minutes** (60 samples),
+and select **Start observation**. Samples arrive every five seconds, starting at
+zero (about 55 or 295 seconds total). Progress shows received samples and the
+original headset alias. There is at most one observation per local app server;
+viewing progress never starts another SSH connection. No terminal, checkout,
+extra dependency or password is needed.
+
+Use **Stop and keep samples** to end local collection. Disconnect, timeout,
+app shutdown or switching to another headset also ends collection. Switching
+network addresses for the same headset does not retarget an existing observation:
+it keeps its captured SSH route and may finish incomplete if that route fails.
+As with the CLI, only the owned local SSH child is terminated. The remote reader
+is bounded and discovers a closed connection on its next write. Desktop sessions
+have a 30-second transport allowance and bounded child cleanup. Stream lines are
+limited to 262,144 characters, sample events to the requested count, and the receive queue
+to count + 2 events; desktop SSH stderr is discarded rather than stored unbounded.
+The existing smoke lock is checked locally before start and remotely before each
+sample; this feature never creates, bypasses or removes that lock.
+
+**Download HTML report**, **Download JSON** and **Download CSV** save local
+snapshots through the browser/app download mechanism. Open the downloaded HTML
+in your browser to view the offline table and its embedded JSON/CSV downloads.
+Snapshots taken before completion explicitly say incomplete. Desktop CSV includes
+`collection.state`, `collection.requestedSamples` and `collection.receivedSamples`
+metadata rows with the original headset alias in the source column, even when no
+sensor sample arrived. CSV text fields, including the alias, are escaped if they
+begin with a spreadsheet formula prefix. JSON records the alias and device ID;
+HTML names the alias.
+
+Only the latest observation is retained in server memory, including partial
+samples after stop or disconnect. **Download before starting another observation,
+restarting the server or quitting the app**: those discard the previous report.
+Page reloads retain server state. Download requests include an observation ID, so
+an old page cannot silently download or stop a replacement observation. Reports
+are not uploaded or automatically opened, and may contain device identifiers,
+OS builds and sensor paths. Review before sharing. The phone-hosted UI does not
+support starting observations.
