 ## Unreleased
 
-- Add an explicit host window-switch button to whole-display panels: Alt-Tab
-  on Windows and Command-Tab on macOS. Single-window panels keep their own
-  source, so the button is hidden there.
-
-- Enable the in-app OBS source Start/Stop control on Windows. A control pipe
-  lets the Python relay close its SSH child on Stop, app quit or parent exit;
-  add a short [Discord guide](docs/streaming-to-discord.md).
-
-- Add a read-only wired connection doctor for a PC using the Frame's observed
-  USB-C network: show the local route, SSH port and pinned-key login result
-  without changing IP, host keys or headset settings.
-  [Usage and limits](docs/wired-connection.md).
-
-- Start the Android app catalogue without waiting for the headset's installed-app
-  list. Browsing remains available if that status request is slow or fails;
-  installation still waits for a confirmed list to avoid duplicate installs.
-
-- Verify the packaged OBS Start and Stop control with a real Frame, and record
-  37.600 seconds of headset mirror video and non-silent output audio in OBS.
-  Listening, sync and active passthrough remain unverified.
-  [Test record](docs/evidence/obs-media-source-real-2026-10-25.md).
-
-- Bundle the OBS source helper in Linux and macOS installers and add a
-  **Capture & Live** Start/Stop control. The app selects the active Frame and
-  closes its SSH stream on a headset switch or app exit. A real Frame stream
-  reached OBS with video and non-silent audio; listening and sync remain
-  unverified. [Setup and limits](docs/obs-headset-source.md).
-
-- Add a source-checkout helper that sends the Frame's SteamVR mirror and
-  default-output audio to a local OBS Media Source. A real Frame supplied a
-  4.021-second H.264/AAC stream to a Linux receiver; OBS playback and sync
-  remain unverified. [Setup and limits](docs/obs-headset-source.md).
-
-- Link emulator setup guidance from Store → Emulators. Existing Steam library
-  shortcuts and artwork cover Android apps and sideloaded titles; Android ROM
-  transfer still needs a verified per-instance workflow.
-  [Guide](docs/emulators.md).

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

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

-Frame Control can send SteamVR's headset mirror and the Frame's output audio to

-source and default-output monitor as **Capture & Live → Record**. It sends a
-local MPEG-TS stream; no port is opened to the LAN or internet.
-
-1. Connect to the Frame and start SteamVR. OBS runs on the computer; the Frame
-   already has `ffmpeg`.
-2. In the **Frame Control desktop app**, open **Capture & Live** and click
