+# Changelog
+
+## Unreleased
+
+- Add a Linux PC Wireless Adapter doctor in Settings and Devices, with a source
+  CLI and local JSON report. Select observed hardware without assuming Valve
+  IDs; inspect USB/interface presence, driver/module binding, udev/permissions,
+  rfkill, channel/band and network manager evidence. Missing evidence stays
+  unknown; all checks are read-only and never contact the Frame.
+  [Usage and verification limits](docs/linux-wireless-adapter-doctor.md).
+
+- Add Linux Tools → Steam desktop sharing: request `steam -pipewire` only after
+  checking Steam is not running, or open KDE Application Permissions with
+  instructions to revoke a verified Steam screen-sharing session manually. No
+  automatic permission reset, Steam restart, or headset access. Frame Control
+  Linux capture remains disabled; live portal behavior is unverified.
+  [Usage and limits](docs/steam-pipewire.md).
+
+- Use gamescope's input for the keyboard and trackpad, following the focused
+  headset panel without installing an input service. Start KDE Connect only for
+  accents and emoji, keeping queued text ordered and cancelling it on headset
+  switches. Retain intended-headset checks before starting either control and
+  prevent Unicode helper startup from deadlocking with a headset switch.
+- Keep accepted keyboard text when the Unicode queue is full: reject new batches
+  before sending their clicks or keys, and count in-flight text toward the limit.
+  Retain unsent text after helper failures/timeouts, report the error and resume
+  it with Try again. Clean up failed workers without touching a new headset's queue.
+  [Current verification and device limits](docs/evidence/pad-gamescope-2026-10-24.md).
+
+- Keep media playback running when SteamVR refuses the optional theatre dark
+  surround, including a retry after standby. Log the refusal and play without
+  the surround. Overlay teardown attempts every owned handle and always calls
+  OpenVR shutdown even if a handle fails to close.
+
+- Check the desktop server's single-instance lock before starting background
+  downloads, so a second server exits cleanly with the existing "already
+  running" message.
+
+- Recheck saved spatial layouts on SteamOS 0.5.6 / SteamVR 2.18.2 (issue #31).
+  Read-only probes expose some panel geometry, but safe restoration of
+  Steam/gamescope docking and positions remains unverified. Record exact API
+  results and a reproducible probe; saved layouts remain unavailable.
+
+- Record packaged v0.4.17 Desktop Capture succeeding on a mapped nested KDE
+  compositor on a real Frame with SteamOS 0.5.6. Headset overlay visibility was
+  not established; this is evidence, not a new fix or resolution of issue #73.
+
+- Correct the Return to Game Mode help text: Frame Control selects the switch
+  supported by the headset's SteamOS build, including `steamosctl` on current
+  Frames. The button's behavior is unchanged.
+
+- Distinguish an unreadable gamescope panel list from a confirmed empty list in
+  Desktop Capture and Control (issue #73). Failed discovery now asks users to
+  check SteamVR and report the exact message and SteamOS version, rather than
+  claiming no panel is open. This does not establish a new capture fix.
+
+- Add an opt-in desktop low-battery alert without starting a family session.
+  Existing status reads confirm low charge and drain; recovery hysteresis and a
+  ten-minute cooldown limit repeat alerts. Off on page open/headset switch;
+  pauses with hidden-page status refreshes. No extra polling or headset changes.
+
+- Clarify first-time desktop downloads, installation and opening on the website
+  and README, including CPU choices, unsigned-app warnings, pairing fallback
+  and the source-only iOS build. Keep section navigation available on mobile.
+
+- Treat headset aliases and other CSV metadata as plain text in power and heat
+  exports, so spreadsheet formula prefixes cannot run when a report is opened.
+
+- Add desktop Tools → Power & heat report: bounded read-only one/five-minute
+  observations with progress, stop and HTML/JSON/CSV downloads. Received samples
+  survive stop, disconnect and headset switch, labeled incomplete and tied to the
+  original headset. Shared sampler/report modules ship with the app; no power or
+  thermal controls are added. Download before replacing a report or quitting.
+
+- Fix Return to Game Mode misidentifying full Plasma Desktop Mode when its VR
+  overlay also runs gamescope (issue #142). Session targets now determine the
+  mode; conflicting or incomplete evidence stays unknown. Use SteamOS's
+  `steamosctl` switch when available, with older selector commands retained.
+
+- Export read-only power and heat observations to an offline accessible HTML
+  report with JSON/CSV downloads. `--html FILE` limits sessions to ten minutes;
+  Ctrl+C saves received samples with an explicit incomplete state. Units,
+  unknown counts and sources remain visible; no headset controls are added.
+
+- Add a guarded `frame-doctor.sh --plan` with read-only, evidence-specific next
+  steps and explicit local baseline reports for before/after diagnostics (issue
+  #34). Restart risk blocks plans/comparisons; no automatic repairs, password
+  changes or headset security changes are performed.
+
+- Recover a tagged release upload when GitHub temporarily displays its draft
+  as `untagged-…` after an edit, without creating a duplicate draft or
+  silently retrying unrelated upload failures.
+
+- Import standalone APK/OBB backups from XAPK/APKS/APKM archives through the
+  existing preview and game-data setup flow. Unsafe archives, split sets and
+  Android/data restores are refused with guidance. This does not establish RE4
+  compatibility or diagnose its reported failure (issue #102).
+
+- Add `scripts/frame-power-sample.sh`, a bounded read-only SSH sampler for
+  battery, CPU, named temperatures, fan and available power rails (issue #52).
+  JSON samples/summaries and CSV exports retain explicit unavailable states;
+  active smoke-test locks stop measurement. No power settings are changed.
+
+- Show saved Android compatibility reports on store search cards and app details.
+  Reports refresh in the background, so a stalled database or credential lookup
+  cannot delay search. Warnings allow installation; build compatibility blockers
+  still apply. Public copies use this computer's reports, not private shared ratings.
+
+- Fix two cases where optional diagnostic logs could retain part of a headset
+  display name or an SSH host name, while preserving existing privacy redaction
+  (issue #81).
+
+- Keep the full host-key recovery explanation readable in Devices, including
+  long addresses, and remove doubled punctuation from the connection tooltip
+  (issue #87). Refresh stays within the header and switching headsets selects
+  the new headset's details.
+
+- Fix experimental PC screen capture on Windows builds whose streaming libraries
+  lack Windows Graphics Capture. Whole screens use Desktop Duplication; individual
+  windows are hidden with an explanation instead of failing when shown. A Windows
+  VM streamed a real desktop to the Frame; physical input remains unverified.
+
+- Add read-only battery health in Tools: charging state, temperature, cycle count,
+  and available capacity with explicit unknown states. The parser was checked
+  on a real Frame; the connected desktop UI was tested with synthetic readings.
+
+- Add Tools → Game storage: read-only headset filesystem capacity and Steam
+  library/game install-size breakdown, with unknown sizes, partial inventories
+  and permission/missing-drive states. Includes instructions for Steam's own
+  Move UI; Frame Control does not move or delete game files. The read-only
+  parser was checked on a real Frame; the connected UI and game moves were not.
+
+- Add `scripts/frame-doctor.sh` for read-only setup and pairing diagnostics,
+  with verified SSH identity, private summaries and actionable next steps
+  (issue #34). Connection steps links to the diagnostic guide. Repairs remain
+  manual; restart-loop evidence stops deeper diagnostics. The real Frame
+  verified the SSH connection and safety stop; deeper checks were skipped.
+- Fixed headset smoke cleanup reporting success while a smoke-title process
+  could remain running after its files were removed. Cleanup now stops and
+  rechecks processes tied to exact reserved test-title paths, uses PID handles
+  for safe TERM/KILL escalation, and records stopped PIDs. Unrelated titles and
+  shared Wine services are left alone. Verified with local Linux process
+  regressions and a 13/13 real Frame smoke run that stopped five test-owned
+  Proton process PIDs before removing the Windows test title.

+
 ## 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).

+# Battery and health monitoring

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

+# 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.

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

+# Windows VM and real Frame test, 2026-10-24
+
+The v0.4.10 installer could enumerate windows/screens and encode a synthetic
+Media Foundation stream, but every desktop capture failed at pipeline parsing:
+`no property "capture-api" in element "d3d11screencapturesrc"`.
+MSYS2's GStreamer 1.28.8 package disables WGC. After the fix, the same installed
+bundle captured the actual Windows desktop with Desktop Duplication and sent
+H.264 to a real Frame: 219 sent frame records, 215 decoded and drawn before the
+snapshot. Individual windows are explicitly unavailable with this bundle.
+
+The base was `e9cbb8fd5555f5cfceeba1babadf2d7d35dcd3be` (`v0.4.10`, origin/main,
+including merged #121), in isolated branch `t3/test-windows-vm-headset`.
+
+## Evidence
+
+- [Capture before the fix](windows-vm-2026-10-24/capture-before.json): five
+  synthetic H.264 frames and five JPEG frames; zero desktop/window frames,
+  with the missing-property error for both codecs.
+- [Actual bundled properties](windows-vm-2026-10-24/plugin-properties.json):
+  `monitor-handle` exists; `capture-api`, `window-handle`, `show-border` do not.
+  [MSYS2 package build](https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-gst-plugins-bad/PKGBUILD)
+  sets `-Dd3d11-wgc=disabled`. Upstream
+  [installs those properties conditionally](https://github.com/GStreamer/gstreamer/blob/main/subprojects/gst-plugins-bad/sys/d3d11/gstd3d11screencapturesrc.cpp).
+- [Capture after the fix](windows-vm-2026-10-24/capture-after.json): the real
+  display produces five H.264 and five JPEG frames. Window sources are hidden
+  with an explicit reason, and the display selects `capture_api=dxgi`.
+- [Raw locked headset session](windows-vm-2026-10-24/headset-session.json):
+  Windows helper, Media Foundation encoder, reverse SSH tunnel, production
+  panel launcher and shared viewer. The image below was captured from that
+  viewer's own X window on the Frame, rather than the VM's console.
+- [Windows tests](windows-vm-2026-10-24/windows-tests.txt) and
+  [guest system details](windows-vm-2026-10-24/windows-system.txt).

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

+## 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.

+# Frame doctor
+
+Run `scripts/frame-doctor.sh` from a checkout on macOS or Linux to diagnose
+first-time setup, pairing and common Frame failures without applying repairs.
+It needs Bash, Python 3 and OpenSSH on the computer, and Python 3 on the Frame.
+Windows users can run `python scripts/frame_doctor.py` with Python and OpenSSH
+installed; the desktop app does not bundle this command.
+
+```sh
+scripts/frame-doctor.sh
+scripts/frame-doctor.sh --alias bedroom --lan frame.local
+scripts/frame-doctor.sh --alias frame --lan 192.168.1.40
+```
+
+Use only addresses belonging to your intended headset. The command tries the
+existing `frame` SSH alias first (Tailscale if setup configured it that way),
+then `frame.local`, then USB-C at `10.86.200.233`. `--alias`, `--lan` and `--usb`
+override those defaults. It reports the successful path without printing its
+address. It neither discovers other devices nor enables Tailscale.
+
+The existing alias supplies the user, port, keys and known-hosts file. LAN and
+USB overrides preserve its `HostKeyAlias`, or its configured hostname if no
+alias was set. A first connection therefore needs trusted setup first. The
+doctor never accepts a new host key, deletes a saved key, generates keys or
+sends a pairing request. It uses your trusted OpenSSH configuration; OpenSSH
+can evaluate `Match exec` conditions in that configuration. Proxy commands,
+jumps, local commands, forwarding and connection sharing are disabled for
+these direct diagnostic connections.
+
+## Reading the result
+
+Each of the eleven runbook sections has one line: `OK`, `WARN`, `BROKEN` or
+`UNKNOWN`. `OK` means only that the stated check passed, not that the whole
+feature works. Optional features that are off may produce a warning.
+
+| Section | Read-only evidence and limits |
+|---|---|
+| 1. Boot and crash history | Previous-boot kernel-oops signatures; one day of coredump history. An oops alone does not prove an unclean reset. |
+| 2. Wi-Fi | NetworkManager's wlan0 state, without SSIDs or connection profiles. |
+| 3. Displays and SteamVR | DSI timeout signatures in the recent kernel journal; no display, compositor or game is launched. |
+| 4. Steam and storage | Free space in home and `devkit-game`, including separate mounts; missing Steam install marker. No CRC scan or restart. |
+| 5. Idle sleep and keep-awake | Existing keep-awake unit state; never takes ownership or changes idle timers. |
+| 6. Remote wake | WoWLAN state, without arming it or testing suspend. Wake with the power button. |
+| 7. Lepton | Recent port-clash, binder and data-clearing signatures; no Android/container commands. |
+| 8. Chromium XR | Crash history; no browser profile or environment inspection. |
+| 9. KDE Connect | Process presence; absence is normal when sharing is off. |
+| 10. Streaming and capture | ffmpeg crash history; no capture or encoder is started. |
+| 11. Panels | Always `UNKNOWN`: placement requires the user's visual confirmation. |
+
+Journal samples are capped at 2,000 entries; current-boot samples cover the
+last ten minutes. This can miss older or high-volume failures. Empty,
+inaccessible or permission-limited journals are `UNKNOWN`, never zero errors.
+Commands time out individually, and each SSH probe is bounded to 90 seconds.
+
+Exit codes: **0** if all reported checks are OK; **1** for warnings, broken or
+unknown checks after connecting; **2** if no authenticated SSH path exists or
+local SSH setup is unavailable. Panel verification currently means a connected
+run normally exits 1. Automation should read the labelled checks rather than
+treating a warning as proof the headset is unusable.
+
+## Read-only repair plan and before/after reports
+
+```sh
+scripts/frame-doctor.sh --plan --save-report before.json
+# Review the plan with the headset user. Any manual action is separate.
+scripts/frame-doctor.sh --plan --compare-before before.json --save-report after.json
+```
+
+`--plan` prints advice; it never executes repair commands or prompts for approval.
+There is no automatic repair mode. Advice about Wi-Fi, display timeouts, low
+storage, a missing Steam install marker or keep-awake requires the exact
+recognized section, severity and evidence. Other warnings request local review;
+unknown evidence never justifies a repair. A signature or missing marker alone
+does not establish a cause. Restart risk, rising counters or unknown counters
+block all section-specific plans and direct you to the recovery runbook.
+Nothing changes passwords, headset security, pairing, services or power settings.
+
+Reports are optional **local** JSON files containing only fixed diagnostic
+summaries, a format version and an opaque SSH-target configuration fingerprint.
+The fingerprint binds comparisons to the same alias, identity/routing
+configuration and fallback addresses; it does not prove physical headset
+identity or that the headset was not replaced behind that configuration. Keep
+using trusted SSH host keys. Report creation is exclusive (existing files and
+symlinks are refused), with owner-only permissions on POSIX. Protect reports
+using your local account permissions on Windows. Choose a fresh output filename
+for each run. Doctor never writes a report on the headset.
+
+`--compare-before` validates a bounded baseline before connecting and refuses
+changed target configuration. It prints each section's before/after status and
+prints both fixed evidence messages when they differ, even if the status
+stayed the same. Changes are observations, not proof a repair worked or caused them;
+recent journal windows can simply age out. There is no intervening repair by
+doctor, freshness guarantee, or authenticated report signature. If either run
+skipped deeper checks, comparison is blocked and no improvement is claimed.
+Unreachable or invalid probes produce no new baseline or comparison. Malformed
+baseline/target mismatch/report-write errors exit **2**; otherwise normal
+diagnostic exit codes apply. No saved report is needed for ordinary diagnostics.
+
+## First-time setup and pairing
+
+- **No SSH response:** wake the headset with its power button. Check the cable
+  or Steam Settings → Internet, then enable Developer Mode. Sleep and network
+  failure can look alike; a timeout cannot distinguish them.
+- **Key rejected:** open **Set Up Connection** in Frame Control. In the headset,
+  open Steam Settings → Developer → **Pair new host**, then approve setup's
+  request. The doctor only checks whether devkit port 32000 responds; that
+  does not prove pairing mode is open or the service is healthy.
+- **Unknown or changed identity:** verify the intended headset through setup
+  or Devices → **Check its key**. Do not delete `known_hosts` to bypass this.
+- **No devkit response:** check Developer Mode and the address. See
+  [SSH setup](ssh.md) for the manual fallback. The doctor cannot turn SSH on.
+
+No password is requested. Enter any password required by the separate setup
+flow only in its local terminal; never paste it into an issue or report.
+
+## Restart safety and recovery
+
+Before deeper checks, and again afterwards, the doctor samples Steam and
+SteamVR `NRestarts` and health-check tracker sizes two seconds apart. Rising
+counters stop diagnostics immediately. Nonempty health-check trackers also stop
+deeper checks even when stable, since a short sample could miss a slower loop.
+Missing counters or counters that reset stop deeper checks as `UNKNOWN`. Stable
+counters with empty trackers still cannot rule out a slower restart loop.
+
+The [historical runbook from PR #33](https://github.com/saphid/frame-control/blob/cce3d940302054ab5246c92d740afaefc4e58d38/docs/frame-doctor.md)
+is the source for these section numbers and observed signatures (September
+2026 builds). Its section 4 describes freezing and verifying health-check
+trackers before prolonged recovery during a live loop. That changes headset
+state, so this read-only implementation stops and directs you there instead.
+The optional plan and baseline comparison are a guarded next step for issue
+#34; automatic fixes and full recovery automation remain unimplemented. Review
+build-specific recovery instructions with the person using the headset; a repair can remove data.
+
+Never reload `ath12k`, suspend remotely, kill gamescope to diagnose a loop,
+reset or force power off during extraction/repair, or write passwords to disk.
+The doctor never restarts services, signals processes, repairs Steam, changes
+WoWLAN/standby settings, takes keep-awake ownership, installs anything or writes
+a remote report. Only `--save-report` creates a local file. Nothing needs
+restoring on the headset after its checks. Manual/device tests must
+follow the [shared-device lock and battery procedure](testing.md#headset-smoke-test).
+
+## Privacy and verification
+
+Only fixed diagnostic summaries leave the remote probe. Raw journals, process
+arguments, environment variables, SSH errors, account IDs, network addresses,
+SSIDs, keys and tokens are not printed. No telemetry or HTTP request is sent;
+the only pairing-service probe is a TCP connection. SSH produces normal access
+logs. Review summaries before sharing them; feature availability can still be
+personal information. Redirecting stdout or using `--save-report` saves a report
+only if you choose it.
+Treat the target fingerprint as private metadata; it is a hash, not encryption.
+
+Unit tests use mocked boundaries. `scripts/e2e.sh test_doctor` covers asleep,
+disk-full, SSH/devkit-off and missing-key faults against the fake Frame. Its
+stable restart counters are explicitly simulated, not proof about SteamOS.
+On 2026-10-24 the script ran read-only against a real Frame, SteamOS build
+`20261015.6141207`. It verified the configured SSH alias and key login,
+then reported `WARN Restart safety`: nonempty health-check trackers. It
+correctly skipped all eleven deeper sections and exited 1. No raw logs,
+addresses or keys were printed, and no repair or restart was attempted.
+This verifies the safety stop on that device; the deeper checks are not
+claimed as headset-tested.
+
+Follow-up verification on 2026-10-24: `--plan --save-report` and then
+`--plan --compare-before` ran read-only on the same real Frame. Both reported
+nonempty health-check trackers, skipped deeper checks and exited 1. The plan
+was blocked and the comparison reported `risk -> risk` without claiming
+improvement. No install, launch, stop or repair was performed; this validates
+the guarded report path, not the deeper checks or any manual repair.
+
+The follow-up's 17 focused offline tests passed. All five doctor fake-Frame
+tests passed, including a disk-full baseline followed by fault removal and a
+fresh comparison. The final evidence-output change also passed that comparison
+test again. Because zsh is unavailable on this host, the repository's images
+were built and its Compose harness run directly under the isolated project
+`frame-doctor-plan-34`; its containers and volumes were removed afterwards.
+These storage changes were fake fault controls, not doctor repairs.

+# Game storage
+
+Open **Tools → Game storage** for a read-only snapshot of the headset's user
+filesystem and Steam libraries. Refresh after an installation, download or move.
+The page never moves, deletes or modifies content, starts Steam, requests root,
+or recursively scans game files. It works through the existing SSH connection.
+
+## What the numbers mean
+
+- **Total, free and used** come from `statvfs` on the headset user's home and
+  each library path. Free is space available to that user; reserved blocks mean
+  used + free can be less than total. These are filesystem sizes, not advertised
+  drive capacity, and do not include separate system partitions.
+- Libraries come from `~/.local/share/Steam/steamapps/libraryfolders.vdf` plus
+  the default Steam library. Modern nested and older numbered-path records are
+  accepted; canonical duplicate paths are shown once. No drive is mounted.
+- Two paths can share one filesystem. Their capacity must **not** be added.
+  An unmounted drive whose mount directory still exists can report the parent
+  filesystem's capacity: the page labels this as the filesystem containing the
+  path, rather than claiming the removable drive is connected.
+- Game sizes are Steam's `SizeOnDisk` records in `appmanifest_<appid>.acf`, sorted
+  largest first, with unknown sizes last. A missing, negative or invalid size
+  is **Unknown**, while an explicit zero remains zero. Records may be stale,
+  including during downloads or moves; they do not measure allocated blocks.
+- Games/apps and runtimes/tools have separate subtotals of **known recorded**
+  sizes. Runtime classification uses names (Proton, Steam Linux Runtime,
+  Steamworks Common, FEX and Lepton Development), so it is only a convenience.
+  Additional apps or runtimes may fall in the game/app group.
+- Saves, Proton prefixes, shaders, workshops, downloads, Android apps,
+  sideloaded games, media and OS files are **unmeasured other usage**. The page
+  does not subtract manifest totals from filesystem usage to invent a size for
+  them. Recorded content is not an exhaustive storage breakdown.
+
+Permission denied, missing/disconnected paths, unavailable filesystem reads,
+invalid metadata and partial inventories are reported separately. A failed read
+is never proof of an empty library. If library discovery fails, other libraries
+may be missing from the view. Refresh clears the old results immediately; a
+headset switch clears the snapshot and ignores late replies from the old device.
+
+## Moving a game safely
+
+Use Steam's own **Settings → Storage** on the headset (or in desktop Steam):
+choose the source drive, select the games and choose **Move**, then pick a
+Steam-supported destination. A second Steam library must already be available.
+Steam may withhold Move or a destination when it cannot perform the operation.
+Let Steam finish, follow Steam's errors/recovery prompts, then Refresh here.
+Do not manually delete files to make room or interrupt an in-progress move.
+
+[Valve's moving guide](https://help.steampowered.com/en/faqs/view/4BD4-4528-6B2E-8327#move)
+was read in a browser on 2026-10-24 and documents this UI. This is an instructional
+handoff: the page does not send a URI or silently open a UI on the headset.
+The guide's separate Windows instructions for moving the entire Steam client
+are outside this feature's scope.
+
+### Why Frame Control does not automate moving
+
+The repository's Valve devkit tools register and launch developer titles; no
+supported game-move operation is provided there. The existing Steam CEF bridge
+uses internal client APIs, which are not a verified supported contract for a
+move transaction. [Valve's public ISteamApps reference](https://partner.steamgames.com/doc/api/ISteamApps) provides install-directory
+and installed-depot queries but no documented move transaction with completion,
+cancellation, rollback and error guarantees. The public support guide describes
+the user-operated Storage UI, rather than such an automation interface.
+
+Consequently this feature adds no move endpoint or guessed internal Steam call,
+manifest rewrite, copy/delete fallback, or custom rollback. Automating a move
+requires a supported interface and verified behaviour for full disks, disconnects,
+running games, downloads, cancellation and Steam restart first.
+
+## Verification and limits
+
+`tests/test_storage.py` runs the actual probe against temporary Steam metadata
+and filesystem/error fixtures. It covers multiple libraries, duplicate paths,
+zero/unknown/invalid sizes, corrupt manifests, unreadable directories and files,
+missing discovery/drives, reserved capacity and read-only file preservation.
+A loopback HTTP test executes the real guarded endpoint with SSH mocked.
+`tests/storage.cjs` runs the production renderer, navigation and refresh handlers
+with DOM/transport boundaries faked, including escaping, offline errors,
+out-of-order refreshes and headset switches. It runs through unittest discovery.
+
+The production storage component was rendered with synthetic data at 390px and
+900px widths; both fit without horizontal overflow. This checks component
+layout, not the full connected application or headset browser.
+
+On 2026-10-24 the uninstalled storage parser was piped read-only over SSH
+to a real Frame running SteamOS build `20261015.6141207`. It reported
+710.4 GiB free on the user filesystem, one available Steam library, 29
+readable app manifests, zero unknown sizes and zero parse/permission issues.
+No game names or raw metadata were printed in the test report. The
+connected UI, removable media, Steam's Move UI and an actual game move were
+not tested. UI and error-state fixtures remain synthetic.

+# 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.

+# Read-only power and heat measurements
+
+Issue [#52](https://github.com/saphid/frame-control/issues/52) starts with
+measurement. `scripts/frame-power-sample.sh` is a bounded, on-demand sampler
+over the existing `ssh frame` alias. It needs Python 3 on both computers and
+an already paired, awake, reachable Frame. It uses strict SSH host-key checking
+and batch mode; it never pairs, prompts for a password or changes SSH security.
+
+```sh
+# Twelve samples, five seconds apart (about 55 seconds), JSON report:
+scripts/frame-power-sample.sh > power.json
+
+# Five-minute observation: samples at 0, 5, ... 300 seconds:
+scripts/frame-power-sample.sh --count 61 --interval 5 > baseline.json
+
+# Long-form CSV samples; JSON summary goes separately to stderr:
+scripts/frame-power-sample.sh --count 12 --interval 5 --csv > power.csv 2> summary.json
+```
+
+Count is limited to 1–720; interval to finite values from 1–60 seconds. These
+are target start-to-start intervals, not guarantees: read latency can delay a
+sample. Wall-clock `time` and monotonic `elapsedSeconds` record actual timing.
+The first sample has no CPU utilization: two valid `/proc/stat` observations
+are required. CPU utilization then covers the interval between observations,
+averaged across the machine, rather than the utilization of one process.
+
+## Start, stop and open an accessible report
+
+From a source checkout with Python 3 and your already trusted `ssh frame`
+connection, start a local observation:
+
+```sh
+scripts/frame-power-sample.sh --count 12 --interval 5 --html power-report.html
+```
+
+Progress is printed on your computer as each sample arrives. Wait for completion,
+or press **Ctrl+C once** to stop local collection and save the samples already
+received. Open `power-report.html` in your browser using its Open File command.
+The file is self-contained and works offline: no server, scripts, external
+resources, account or upload. It includes a table with named metrics, source
+paths, units, minimum/mean/maximum/last values, and available/unknown counts.
+Keyboard users can focus the table region to scroll through its columns.
+Charging states and entirely unavailable sensor families remain explicit.
+Use **Download JSON samples and summary** or **Download CSV samples** to save
+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.
+
+## What it reads
+
+- Battery percentage, driver charging state, signed battery watts and battery
+  temperature, using the same parser as Frame Control's battery details.
+  Positive battery watts mean charging on the Frame fuel gauge; negative means
+  discharge. `Not charging` alone does not prove a charger is connected.
+- CPU utilization from `/proc/stat`; GPU clock from the known Frame devfreq path.
+- Named thermal zones in °C, with zone names retained. A thermal zone is not
+  automatically a CPU sensor; there is no inferred “CPU temperature” or safe
+  temperature threshold.
+- hwmon power channels, labels and driver names in watts. `vph` is the measured
+  system rail, not power at the wall. CPU `apc*` and GPU `gfx` rails are separate
+  readings; do not sum all channels as if they were independent power consumers.
+- Fan RPM and the Frame fan driver's raw `pwm1`. No generic percentage conversion
+  is assumed. The historical Frame driver reported a percent-like value of 41.
+- Named IIO board temperatures, PM8550B input/charge current in amps, and raw
+  VCNL4000 proximity if the account can read it. Raw proximity has no inferred
+  worn/unworn threshold.
+
+Each metric includes its unit, source path and availability state. Missing,
+unreadable or invalid values are JSON `null`, not zero. A missing sensor family
+is also listed in each sample's `unavailableGroups`; CSV adds unavailable group
+rows. Numeric zero remains a valid reading. The OS build is recorded per sample
+when `/etc/os-release` is readable; hostnames, addresses, machine IDs, process
+lists, logs, screenshots and application inventories are not collected.
+
+The JSON report contains raw samples and a summary per metric: available and
+unavailable counts, numeric minimum/maximum/arithmetic mean/first/last, or the
+observed charging states. Means exclude unavailable readings. They are sample
+means, not time-weighted energy or battery-runtime estimates. Different sample
+availability and intervals must be considered when comparing sessions.
+
+Numeric validity does not establish sensor accuracy. Historical readings
+already showed an apparently absent/broken right-display thermistor near
+−16 °C. This firmware also reports one charger-lite die sensor at −60 °C.
+Those raw numbers remain visible for diagnosis; neither should be used to
+infer cooling performance or safety. This tool does not diagnose heat, explain
+a spike, predict battery health, or promise power savings.
+
+## Safety and shared-device use
+
+Only file reads under `/proc`, `/sys` and `/etc/os-release` run on the Frame.
+The Python sources are sent on SSH stdin and not installed on the headset.
+There is no sudo, OpenVR initialization, service call, settings write, process
+control, journal query, wake, suspend or reboot. No daemon, telemetry upload or
+automatic measurement is added. Redirects above write only to your computer.
+The observer itself uses a little CPU and SSH traffic, so label baseline
+conditions and avoid interpreting very small changes as savings.
+
+The sampler checks `/tmp/frame-test.lock` on the computer before SSH, and on
+the Frame before any probe and before each sample. If a smoke session is active,
+it exits 75. A lock appearing mid-run stops the next sample, retains earlier
+samples, sets `stopped`, and exits 75. It never removes or acquires another
+session's lock. This is an advisory check, not an atomic lease: a smoke session
+can start during a file read. Coordinate sessions and defer measurement when
+timing overlaps. It does not block someone else from starting a smoke test.
+
+SSH failures/timeouts return a nonzero exit and an explanation, without
+presenting a zero or an old report as a successful measurement. Fully missing
+sensors can still produce a successful report with explicit unavailable states.
+On a connection failure, partial samples buffered on the headset can be lost.
+
+## Evidence and remaining work
+
+Read-only checks on **2026-10-24**, SteamOS **0.5.6**, build
+**20261015.6141207**, confirmed battery, CPU ticks, thermal zones, rail power,
+fan, GPU clock, board temperatures and charger current through the final
+sampler. Proximity was unavailable. Both JSON and CSV paths were exercised;
+see [the recorded results](evidence/power-sampler-2026-10-24.json).
+No smoke lock was present at the preflight or sampler checks. No settings,
+services, application state or device files were changed. This short run is
+a parser/transport check, not a controlled baseline or a worn-headset test.
+
+The original planning document is in commit `fe132e3` (2026-09-29). It recorded
+an off-head, charging idle baseline of about 4.71 W, CPU zones around 40–45 °C,
+and about 8,350 fan RPM on build 20260925.6191901. Those conditions and firmware
+differ from the current check; comparisons do not establish a regression.
+
+This change completes only the sampler portion of “Plan: leave it on, but
+cheaply.” Controlled worn/home-space, streaming/game load and unplugged
+baselines, and the cause of the 2026-09-28 95 °C spike, remain uninvestigated.
+Quiet mode, compositor changes, CPU/fan/charging changes and remote-wake tests
+are separate work. No controls are offered here. Follow the shared-device
+procedure in [testing.md](testing.md#headset-smoke-test) for future experiments.
+
+The accessible HTML export was checked on the same build on **2026-10-24**:
+three streamed samples, 91 metric summaries and 276 CSV data rows. Chromium
+preview checks at 1280 px and 390 px confirmed the table stays in its scroll
+region; both browser downloads matched the original samples. See
+[export evidence](evidence/power-export-2026-10-24.json). Ctrl+C retention and
+local process cleanup were tested with local subprocess fixtures, not on the
+real headset. Screen-reader, Windows and macOS checks were not performed.
+
+Offline validation:
+
+```sh
+python3 -m unittest discover -s tests -p 'test_power*.py' -v
+bash -n scripts/frame-power-sample.sh
+python3 -m py_compile scripts/frame_power_sample.py scripts/frame_power_report.py
+```
+
+Fixtures cover units, signed and zero values, missing/malformed/permission-denied
+readings, named/discovered channels, unknown charging state, CPU warmup,
+summary counts, CSV quoting, strict SSH transport and smoke-lock interruption.
+
+Export fixtures also cover HTML escaping, download round trips, zero versus unknown,
+stream completion/failure, smoke-lock stop, timeout, Ctrl+C retention, local child
+cleanup, duration bounds and refusing to overwrite reports.
+
+Desktop validation on **2026-10-24** covered API start/stop, a synthetic browser
+observation with partial exports, shared-module resource staging under isolated
+Python and missing-resource build guards. A real Frame probe under this task's
+owned smoke lock correctly returned zero samples with an explicit incomplete
+reason; no successful live sensor baseline or native installer run was performed.

+# Steam desktop sharing on a Linux PC
+
+**Tools → Steam desktop sharing** helps with Steam's own `steam -pipewire`
+desktop-in-headset flow on a local Wayland PC. It needs no Frame connection.
+It is separate from Frame Control's [PC in the headset](pc-in-headset.md),
+which remains disabled on Linux. Steam and the desktop portal own the capture,
+screen picker and headset flow; this helper does not provide a stream.
+
+## Launch Steam with PipeWire
+
+Save your game and use **Steam → Exit** first. Then click **Launch Steam with
+PipeWire**. Frame Control checks this user's local processes, finds `steam` on
+PATH, and requests `steam -pipewire`. This flag applies to that launch only.
+No Steam settings, login files or startup entries are changed. An existing
+Steam session is never stopped, signalled or silently switched.
+
+If Steam or a Steam launcher/helper is running, the button explains that Steam
+must be exited first. If the process inventory cannot be read, it refuses to
+launch. It also refuses root, SSH, headless, X11 and Flatpak-sandboxed Frame
+Control sessions. Run Frame Control as your normal user in the local Wayland
+desktop with its session bus.
+
+For a Flatpak-only Steam install without a `steam` command on PATH, the helper
+provides a manual command instead of choosing an installation for you. After
+exiting Steam, run `flatpak run com.valvesoftware.Steam -pipewire` in a local
+terminal. Flatpak Steam processes are included in the existing-session check.
+
+A successful request is **not confirmation of a picker or stream**. Steam may
+exit or fail after the initial check, and another launcher can race the local
+process check. Do not start Steam elsewhere at the same time. If nothing opens,
+run the command yourself in a terminal to see Steam's error.
+
+## Reset screen-share choice
+
+Click **Reset screen-share choice…** to request KDE's **Application Permissions**
+page. This button does **not** revoke anything or report a completed reset.
+Frame Control cannot reliably map a Steam runtime display name to a
+Steam-specific portal grant or restore token across backends. It never reads,
+edits or clears the portal permission store or Steam tokens.
+
+On KDE:
+
+1. Open **System Settings → Applications → Application Permissions** if the
+   button cannot open it.
+2. Find the entry for Steam. The Ubuntu 26.04 KDE report showed **Steam Linux
+   Runtime 3.0**. That display name alone is not proof that every session there
+   is safe to remove; verify the session belongs to your Steam desktop share.
+3. Under **Screen sharing**, choose **Manage 1 Session** (the count may differ).
+4. Choose **Revoke** for that verified session only. **Do not use Revoke All**
+   or change another application's grants. If ownership is ambiguous, stop.
+5. Retry Steam's desktop sharing flow. The reporter saw the portal picker again
+   after revoking that session. Results can differ by Steam and portal version.
+
+The reported entry sometimes appeared intermittently. If it is missing, do not
+clear other entries or the whole portal store. Check again when Steam's sharing
+session is present. If **Application Permissions** itself is missing on
+Ubuntu/Kubuntu, check your distribution's `kde-config-flatpak` package: the
+reporter needed that package and a reboot before the page appeared. Frame
+Control does not install packages, reboot, request root or change security
+settings. Older KDE modules may lack this page; other desktops receive guidance
+only, with no automatic reset or guessed permission target.
+
+The launcher uses `kcmshell6 --list` to verify the exact module, then
+`kcmshell6 kcm_app-permissions`. It does not substitute the older Flatpak-only
+page. A request to open the page does not prove that a window became visible.

+feature remains disabled. Live picker behavior still needs desktop validation.

+Smoke process cleanup runs before and after title removal and during the
+initial/final leftover sweeps. It targets only the reserved `fc_smoke_arm64`,
+`fc_smoke_x86_64`, `fc_smoke_exe` IDs and their legacy `fc-smoke-` equivalents.
+On the target, `tests/smoke/stop_processes.py` requires the SSH user's uid and

+argument; similarly named folders and shell command substrings do not count.
+Deleted cwd/exe paths still count, so a process left after file removal can be

+another three-second bound, rescanning for survivors. PID handles prevent PID
+reuse from signalling another process. Linux Python 3.9+ with pidfd support
+is required; missing support, signal errors and survivors fail the
+cleanup step. Stopped PIDs are recorded in the results JSON.

 Point `GITHUB_REPO` in `.dev.vars` at a scratch repo when testing locally so test issues don't land on the real tracker.
+
+## First-run verification
+
+Before changing download or setup instructions:
+
+- Compare every linked filename with `gh release view --repo saphid/frame-control --json tagName,assets`.
+  Browser OS hints cannot establish CPU architecture; keep every platform choice visible.
+- Run `node --test site/test/*.test.mjs` from the repo root, plus
+  `node --check site/public/js/site.js` and `node --check site/public/js/feedback.js`.
+- Serve `public/` locally (for example `python3 -m http.server 8793 --directory site/public`
+  from the repo root). Check 320px, 390px, 768px and desktop widths: section navigation,
+  the hero link, download cards, opening-help links, feedback and privacy pages. Check
+  horizontal overflow and that anchor targets clear the sticky header. Repeat with
+  JavaScript disabled: downloads and navigation must remain available.
+- Check setup labels against `app/main.js`, `scripts/connect.sh`, `ui/frame_connect.py`
+  and the Devices page. macOS discovery failure exits; Windows/Linux prompt for an IP.
+  The app's Devices → Add a headset dialog can pass an explicit address on all platforms.
+- Separate website checks from native installation and real-headset pairing evidence.
+  A successful page/link check does not verify an installer or headset approval flow.
+
+On 2026-10-24, the first-run update was checked against published v0.4.16 assets:
+all seven linked desktop installers returned HTTP 200 after redirects, as did the
+linked GitHub documentation and trailer. Local page/resource links and section
+fragments were checked; navigation stayed visible without horizontal overflow at
+320, 390, 768 and 1280 CSS pixels. Native macOS/Windows installs and real-headset
+pairing were not exercised for this documentation change. No site deployment was
+performed.
