+## Control Center
+
+Open **Control** or `#control` to search controls, status and help. Categories
+cover device/audio, VR/comfort, apps/files, connection/remote and Frame Control
+preferences. Search is local: it matches labels, descriptions and familiar terms
+such as “DPI”, “microphone”, “recenter” and “keep awake”. Queries are not sent to
+Steam, app catalogues, analytics or models. Choosing a workflow link opens its
+existing screen; it does not install, cast, open a helper or change a setting.
+Home, Games, Android, Tools and Devices retain their existing features.
+
+The overview and detail cards use the shared `/api/status` sample: charge and
+power, user/system storage, memory, Wi-Fi, IP, OS/build, uptime, detected services
+and VR timings. Values refresh with the normal 30-second poll. A failed status
+request, lost connection, headset switch or sample received more than 90 seconds
+ago clears current readings and disables audio writes. The client receipt time
+and failed-read state are retained through page startup and UI redraws. Only a
+new successful status read clears a failure; reusing the retained sample does not.
+The headset timestamp is shown without assuming
+its clock matches this computer. Missing sensors show **Unavailable**;
+they are not converted to zero. Compositor FPS is separate from application FPS;
+GPU time is render time, not GPU utilisation. The temperature is the hottest
+readable sensor. Thermal trip warnings use per-zone kernel hot/critical limits,
+not a guessed universal temperature threshold.
+
+**Audio** controls the default output sink through the existing `/api/volume`
+endpoint. Moving its slider prepares a value; **Apply volume** sends it. **Mute**
+and **Unmute** send explicit mute states. The UI captures the selected headset,
+blocks duplicate/pending actions, and requests status after command acknowledgment
+for readback, draining an earlier poll first. Mute preserves an unapplied volume
+draft; switching headsets discards it. It reports
+unconfirmed or differing output separately from confirmed state. API validation
+rejects invalid types, out-of-range levels and invalid mute states before SSH.
+
+Other settings link to the existing forms and their validation, progress,
+confirmations and reset behavior: per-instance Android resolution/density/text,
+comfort sessions and alerts, media layouts, Mac streaming quality, privacy,
+sources and artwork. Android display links reveal **On your Frame** before
+scrolling to the form. Mac streaming remains searchable on all platforms, with
+its action shown only when the server is on macOS.
+
+Hardware guidance is deliberately separate from controls. Microphone/routing,
+brightness, refresh selection, optics, controllers, Bluetooth, passthrough,
+tracking-origin changes, saved spatial layouts, firmware updates and recovery
+have no verified remote setting here. Use the headset's own controls or the
+documented manual procedures. Movement comfort remains per-game; automatic
+sleep is in Steam Settings → Power → Sleep after inactivity. Keep-awake and
+Android data backup/restore remain script/MCP capabilities, not new UI switches.
+
+**Verification:** the Control Center's JavaScript runs under Node with mocked
+API and DOM boundaries; the server tests mock SSH and reject invalid values
+before any device command. Packaging tests cover the shared CSS/JS in desktop
+and iPhone bundles. These checks establish wiring, search, navigation, offline,
+error and device-switch behavior; they do not establish wearer experience,
+physical settings persistence or a new hardware capability.

-# My Meta library (Experimental)
-
-Install Quest games your Meta account owns straight from Meta, test whether
-they run on the Steam Frame, and add the result to the shared compatibility
-reports. It is off until you connect, and it lives in **Android → My Meta
-library**.
-
-**Read this first.** My Meta library uses Meta's undocumented internal API
-with your own Meta access token, as the open-source tools QAVS, DownQuest and
-BSManager do. It may stop working whenever Meta changes things, and using it
-may be against Meta's terms. Your account is your responsibility. Frame
-Control is unofficial and not made or endorsed by Meta or Valve.
-
-What it will and won't do:
-
-- It lists and downloads only games your account owns (its active
-  entitlements). It never downloads anything else.
-- It installs games as Meta ships them. There is **no licence-check bypass**:
-  no patching, no stub libraries, no OVRPort or FramePort. A game that
-  enforces Meta's licence check may quit or hang on the Frame, because that
-  check needs Meta's services, which the Frame doesn't have.
-- Game files go only to a cache folder on your computer and then to your
-  Frame. They are deleted from the cache after each install, and never
-  uploaded or shared. Reports carry results only (below), never files or your
-  token.
-
-## Your token
-
-Frame Control never reads your browser's cookies. There are two ways to give
-it your token.
-
-**Sign in with Meta** (desktop app only; a plain browser doesn't show it).
-Tick **I understand…**, then choose **Sign in with Meta…**. Meta's own login
-page (`https://secure.oculus.com`, the address BSManager's "Log in with Meta"
-opens) appears in a Frame Control window. Sign in there as usual. When Meta's
-site sets its access token cookie (`oc_ac_at`), Frame Control takes it from
-that window, connects with it exactly as if you had pasted it (below), and
-closes the window. The window:
-
-- has its own storage (the Electron session `persist:meta-signin`), separate
-  from Frame Control's main window and from every browser on your computer;
-  the cookie is read only from there, and only for `oculus.com`;
-- runs Meta's page sandboxed, with no access to Frame Control (no preload, no
-  Node, context isolation on, no developer tools) and every permission request
-  or check (camera, notifications…) refused;
-- only goes to `https://` pages on `oculus.com`, `meta.com`, `facebook.com` and
-  `instagram.com` (and their subdomains; Meta's login passes through Instagram).
-  A link anywhere else opens in your system browser; a redirect anywhere else
-  is stopped, and closing the window then says where it went. Pop-ups on those sites open in the same
-  window. Frames inside the page may load any `https://` page (Meta's login
-  can embed captcha and CDN frames from other sites, such as Arkose Labs,
-  hCaptcha, reCAPTCHA or fbcdn) or an empty frame (`about:blank`,
-  `about:srcdoc`); a frame going to any other scheme (`http:`, `data:`,
-  `blob:`, `javascript:`, `file:`…) is just stopped. Redirects follow the same
-  rule for the frame they happen in. Frames can't reach the
-  token: the cookie is read by Frame Control's main process, and the window
-  has no IPC;
-- sends a cookie value on only if it looks like a user token (`OC` or `FRL`,
-  mixed case, no `%`, `|` or `:`), and each value once. If the server refuses
-  it, the window stays open; close it to see why;
-- gives up after 10 minutes, as BSManager does;
-- when it is closed, times out or is signed out of, stops reading cookies
-  first, then is destroyed (a page's "leave this page?" can't keep it open),
-  and, if it had sent a token, tells the server to drop that sign-in: each
-  sign-in has a random attempt id. The cancel is sent only once the connect
-  under way has finished (saved, refused or failed), so the server always
-  gets it after the connect; with nothing sent, there is nothing to cancel.
-  The server lists an attempt only while its
-  connect is being checked: cancelled then, it isn't saved; cancelled just
-  after its token was saved (even before the connect has finished tidying
-  up), that token is deleted (as a disconnect). A cancel
-  never removes an account a later sign-in or a pasted token saved, and one
-  for an unknown attempt changes nothing.
-
-The page never sees the token: the desktop app hands it straight to the local
-server's connect path and tells the page only the answer (connected, and your
-Meta display name). It isn't logged anywhere.
-
-The window keeps you signed in to Meta (in `persist:meta-signin` only) until
-you **Disconnect**, which also signs out of Meta in Frame Control: it clears
-that window's cookies, storage and cache, so the next sign-in starts fresh.
-**Sign out of Meta in Frame Control** next to the sign-in button does just
-that part, for a sign-in that didn't connect.
-
-**Paste a token.** You copy your own token and paste it in. The two ways
-BSManager's guide describes
-([How to obtain your Oculus Token](https://github.com/Zagrios/bs-manager/wiki/How-to-obtain-your-Oculus-Token)):
-
-1. **From the Meta website.** Sign in at `https://secure.oculus.com`. Open the
-   browser's developer tools, then **Application** (Chrome, Edge) or
-   **Storage** (Firefox) → **Cookies** → `https://secure.oculus.com`. Copy the
-   value of `oc_ac_at`. It starts with `OC`.
-2. **From the Meta Quest PC app** (Windows). Press **Ctrl+Shift+I**, open
-   **Network**, press **Ctrl+R**, type `graph` in the filter, open the first
-   request, and copy the access token from its **Payload**. It starts with
-   `FRL`.
-
-Treat it like a password: anyone with it can act as your Meta account. Signing
-out of the Meta website or app usually ends it; then connect again with a new
-one.
-
-Frame Control refuses values that can't be a user token before sending them
-anywhere: anything not starting with `OC` or `FRL`, URL-encoded copies (with
-`%`), app tokens (with `|` or `:`), cut-off values (under 20 characters), and
-anything with characters other than letters, digits and `+ / = - _` (the
-base64 and URL-safe base64 sets), or with no lower-case letter (real tokens are
-mixed case). The public tools only describe tokens made
-of letters and digits; if a real token needs another character, it has to be
-added in one place (`TOKEN_CHARS` in `ui/frame_meta.py`), which also makes
-the redaction look for it.
-
-## Using it
-
-1. Tick **I understand…**, then either choose **Sign in with Meta…** (desktop
-   app) or paste your token and choose **Connect**. Frame Control asks Meta
-   "who am I" with it (a read-only query); only a token Meta accepts is kept.
-2. Your Quest games are listed with their version, size, game data, and the
-   community verdict from the compatibility database when there is one.
-3. **Install** downloads the game and installs it on the Frame, as [Import
-   from my Quest](quest-import.md) does. A game with OBB game data then needs
-   a second **Install** while you have it open on the Frame: Frame Control
-   downloads the data, copies it in and closes the game.
-4. **Install and test** does the same, then starts the game itself (twice if
-   it has game data to add: once to add it, once for the test), watches it for
-   about 30 seconds, and records what happened. **Test again** repeats only
-   the test.
-5. **Disconnect** deletes the token from your computer and, in the desktop
-   app, signs out of Meta in Frame Control (clears the sign-in window's
-   storage). Games already on the Frame stay.
-
-From a terminal (the token is read from standard input, never an argument):
-
-```sh
-python3 ui/frame_meta.py connect --token-stdin      # paste the token, press Enter
-python3 ui/frame_meta.py status
-python3 ui/frame_meta.py list [--refresh]           # owned Quest games, with community verdicts
-python3 ui/frame_meta.py download APP_ID            # into the local install cache (a later download clears it after 6 hours)
-python3 ui/frame_meta.py install APP_ID [--test] [--allow-downgrade]
-python3 ui/frame_meta.py test com.example.game [--wait 30] [--no-report]
-python3 ui/frame_meta.py disconnect
-```
-
-The local API: `GET /api/meta` (connected or not, never the token),
-`GET /api/meta?library=1[&refresh=1]` (the games), and `POST /api/meta` with
-`{"action": "connect", "token": "...", "acknowledged": true}`,
-`{"action": "disconnect"}`, `{"action": "cancel-signin", "attempt": "..."}`, `{"action": "install", "app": "APP_ID", "test": false,
-"allowDowngrade": false}` or `{"action": "test", "package": "..."}`. Install and
-test return a background job (`/api/job`). Sign in with Meta uses the same
-`connect` action: the desktop app's main process (`app/meta-signin.js`) posts
-it with the cookie's value and an `"attempt"` id (8 to 64 letters, digits or
-`-`) once the page's acknowledgement box is ticked. A connect whose attempt
-was cancelled while it was checked answers 409 and saves nothing;
-`cancel-signin` for an attempt whose token is the saved account deletes it.
-
-## What an install does
-
-1. Checks the game is in your library (by its Meta app id), and that there's
-   room on this computer for the APK, a patched copy of it and the game data.
-2. Downloads the APK from Meta's download server, within the size Meta
-   declared (and at most 2 GB), checking its SHA-256 if Meta gives one, and
-   that it is an APK of the package and version Meta said.
-3. Runs Import from my Quest's checks. Refused: 32-bit-only builds (no
-   `arm64-v8a`), and apps that need an Android newer than Lepton's (API 30).
-   Installed with a warning: games that use Meta's licence check
-   (`libovrplatformloader.so`), and VrApi-only games ("may not run").
-4. Installs it with `frame_android.install` (VR detection, the launcher fix,
-   the OpenXR compatibility layer, artwork, a Steam library entry). An older
-   copy never silently replaces a newer one on the Frame unless you tick
-   **Allow replacing a newer version**.
-5. Game data: the app's OBB (saved as Meta names it when that is a standard
-   `main|patch.<version>.<package>.obb` name, otherwise as
-   `main.<version code>.<package>.obb`) and any *required* asset files with
-   standard OBB names, at most 8 GB each. One install downloads at most 16 GB
-   in all, APK included, counted as the bytes arrive (so files whose size Meta
-   doesn't give count too); a file that goes past it is stopped and removed.
-   The data is copied into the
-   running game by the same two-step helper Import from my Quest uses. Other
-   asset files (DLC packs, `.pak` files a game fetches through Meta's
-   Platform SDK) aren't downloaded; the result lists them.
-6. Deletes everything it downloaded, whether the install worked or not.
-   Downloads left by a crash are removed after six hours.
-
-## The test, and the report
-
-The test starts the game, waits for its Lepton instance, then looks every 10
-seconds for 30 seconds: is the game's process alive, and what does its Android
-log (main, system and crash buffers) say. It recognises:
-
-| In the log | Cause given |
-|---|---|
-| "entitlement check failed", "not entitled", `ovr_Entitlement…` or `IsUserEntitledToApplication` reporting a failure (a call that passes doesn't count) | Meta's licence check failed |
-| Platform SDK initialisation errors | Meta's Platform SDK couldn't start |
-| `Failed to launch SystemActivities`, "device not supported" | The game checks it is on a Meta Quest |
-| `vrapi_… was called before…`, VrApi load errors | Legacy VrApi |
-| `XR_ERROR_EXTENSION_NOT_PRESENT` (with the extension's name) | An OpenXR feature the Frame lacks |
-| `XR_ERROR_API_VERSION_UNSUPPORTED`, runtime/initialisation failures | OpenXR version or session problems |
-| `VK_ERROR_DEVICE_LOST`, `zink`, `libgallium_dri.so`, `GL_INVALID_…`, shader failures | Graphics driver errors |
-| `ClipboardManager` | Lepton's missing clipboard service |
-| `NoSuchMethodError`, `UnsatisfiedLinkError`, `dlopen failed` | Android or library features Lepton lacks |
-| `FATAL EXCEPTION`, `Fatal signal`, `SIGSEGV` | A crash |
-| `ANR in …`, "Input dispatching timed out" | Not responding |
-| `XR_SESSION_STATE_SYNCHRONIZED/VISIBLE/FOCUSED`, `xrEndFrame` | The VR scene started |
-
-The outcome is one of **runs** or **runs with issues** (its VR scene
-started), **quits** (closed by itself), **crashes**, **hangs** (Android
-reported it not responding; Frame Control then closes it, and says so if it
-couldn't), **didn't start** (its instance never came up), or **no clear
-result**: it stayed open but its log never showed its VR scene starting. That
-can be a game still loading, or one stuck after a failed check; Frame Control
-can't tell, so it doesn't record it. A game already open is closed first, so
-the test starts clean; if it can't be closed, nothing is tested. If the Frame
-fails while the test reads the game or its log, the test says only that it
-couldn't read the log: a failed command's output can be the game's log, so it
-is never shown. Signatures look at the first 4 KB of each log line and are
-bounded, so a huge or hostile log can't make the test slow. They
-are written for Frame Control from the research in [vr-apks.md](vr-apks.md);
-they are not copied from other tools.
-
-The result goes through the same path as **Test** and **Report**
-(`frame_catalog.add_report`): `via` probe, source `meta-store`, the result
-(`runs`, `crashes` or `instance_failed`, the values the database accepts), and
-notes with the outcome, the cause, the names of the matched signals and the
-version code, all fixed texts. Nothing else: no token, account name, file or
-log text. The page may show a short name from the log next to the cause (an
-OpenXR extension, a library, an exception class or a signal), taken from the
-log line after the token is removed from it, and left out unless it looks like
-a real name (64 characters at most, no long mixed letter-and-digit runs);
-reports never carry it. It is always kept on this
-computer; it reaches the shared database only if **Share compatibility
-results** is on in Privacy settings, as for every report. The panel offers to
-turn that on.
-
-## Your token and privacy
-
-- Kept in `meta-account.json` in Frame Control's per-user data folder
-  (`~/Library/Application Support/Frame Control` on macOS,
-  `%APPDATA%\Frame Control` on Windows, `~/.local/share/frame-control` on
-  Linux), written owner-only (0600) through a temporary file. Never on the
-  Frame.
-- Sent only to `graph.oculus.com` (in the POST body) and
-  `securecdn.oculus.com` (in the download address, which is how that server
-  takes it), over HTTPS. A download that redirects elsewhere (Meta's CDN) is
-  followed only to a plain HTTPS address on port 443 that doesn't carry the
-  token in any form, anywhere (host, path, query or fragment; literal,
-  recased, percent-encoded, or 8+ characters of it), nor an `access_token`
-  parameter. That is checked before any lookup or connection, and a redirect
-  that fails it is refused. API answers that redirect are refused.
-- Every connection goes to an address checked to be public (an allow-list:
-  no private, local, shared, reserved, multicast, NAT64, 6to4 or Teredo
-  addresses), and to exactly that address, with TLS checked for the host
-  name, so a second DNS answer can't swap in another. System proxy settings
-  aren't used. This is the same design as the itch.io purchases branch.
-- Never in logs, error messages, API answers, the page or reports: every
-  message is cleaned first, matching the token (or any start of it of 8+
-  characters) in any letter case, with each character written literally or
-  percent-encoded once or twice (%XX, %25XX) in either case, and any other
-  token-shaped value, before it is shortened.
-- Disconnect deletes the file and the library Frame Control holds in memory,
-  and stops a download under way. A connect still being checked when you
-  disconnect is not saved. In the desktop app, before the token is deleted, it
-  also stops any sign-in under way, destroys the sign-in window, waits for a
-  connect still under way to finish and cancels its attempt (deleting its
-  token if it was just saved), and only then clears the `persist:meta-signin` session
-  (cookies, storage, cache); no other session is touched. Sign in with Meta
-  stays off from the moment you press Disconnect until the token is deleted,

-Frame Control's code is its own (MIT). These public sources describe the
-protocol; Frame Control takes only facts from them (addresses, query ids,
-field names), not code. QAVS and BSManager are GPL-3.0; OculusGraphQLApiLib,
-DownQuest and Oculus-downgrader state no licence.

-**Assumed, not seen in those sources:** that the entitlement and binary
-answers carry the fields above in the shapes the libraries' models describe
-(the stored queries are opaque); that the list isn't paginated (none of the
-tools page it); that `ANDROID_6DOF` marks Quest apps; where downloads redirect
-to (the tools let their HTTP client follow redirects; Frame Control follows
-up to five, to any public HTTPS host, and refuses one carrying the token); and
-a `sha256`
-field (none was seen, so in practice only sizes are checked). The log
-signatures for the test are inferred from the compatibility research, not
-from a real Frame.
-
-## Evidence and limits
-
-**Verified locally** with a fake Meta and a fake Frame (`tests/test_meta.py`):
-token checks; storage owner-only through a temporary file; redaction (the
-stored token recased and percent-encoded in either case, starts of it, other
-token-shaped values, and redaction before cutting); HTTPS-only URLs; the
-public-address allow-list, resolving once and connecting only to a checked
-address within one deadline; redirects off Meta's hosts refused when they
-carry the token anywhere, before any lookup; the token never sent to the
-CDN; GraphQL redirects refused; disconnect beating a connect in flight and
-stopping a download; library parsing (Quest apps only, nothing expired or
-inactive, details from the binary query); downloads with an OBB; size, length
-and checksum limits and the whole-install budget with nothing left behind;
-refusing apps not in the
-library; the handoff to Import from my Quest's checks, install and data step;
-the licence-check warning instead of a refusal; test outcomes from log
-fixtures (a passing licence check isn't a failure; no VR scene is no clear
-result, not recorded); closing before a test and saying when a close failed;
-reports carrying only fixed texts, no token, log text or file names. The
-real TLS connection code is the same as the itch.io branch's and is exercised
-here only with a fake connection.
-
-**Sign in with Meta, verified locally** with fake Electron windows, sessions
-and cookies (`app/test/meta-signin.test.js`): the window's options (its own
-partition, sandbox, context isolation, no Node, no preload) and Meta's login
-address, no developer tools; permission requests and checks refused; the
-navigation allow-list (links elsewhere open in the system browser, redirects
-elsewhere are stopped, pop-ups never become windows); frames allowed any
-HTTPS page but no other scheme, the window itself only Meta's sites; a
-page's beforeunload not keeping the window open; the cookie read only from
-`persist:meta-signin` and only for `oculus.com`, even when the default
-session and another partition hold one; signed-out values ignored; a value
-sent once, a refused one keeping the window open; the window closing after a
-connect, with the page getting the answer and never the token; nothing
-logged, and a server error that echoed the token scrubbed; closing the window
-or signing out ending the wait; closing, timing out or signing out during a
-connect cancelling that attempt (with its own id) after cookie intake stops
-and only after that connect settles (saved, refused or failed), and no cancel
-when nothing was sent; sign-out (Disconnect's first step) waiting for a
-connect under way, even from a window closed earlier, before it finishes;
-sign-out destroying the window before clearing only that partition; no
-sign-in starting while a sign-out runs (it is refused: "try again in a
-moment"), a second sign-out joining the first, and a sign-out waiting for
-every window and connect started before it. The
-frame redirects held to the frame rule, the window's to Meta's sites. The
-server side (`tests/test_meta.py`): an attempt cancelled while Meta is
-answering not saved, even after 300 other cancels; a cancel just after the
-save deleting that token; a cancel never removing a later sign-in's or a
-pasted token's account; unknown attempts changing nothing; no attempt left
-listed after a connect, refused or not; attempt ids checked.
-
-**Differences from BSManager:** BSManager uses its app's default session (and
-clears only `.oculus.com` cookies afterwards); Frame Control uses a session of
-its own and clears all of it on disconnect. BSManager waits for
-`/my/profile`; Frame Control also reacts to the cookie changing, and to any
-`oculus.com` page, and lets the server decide whether the value is a
-working token.
-
-**Not verified:** Sign in with Meta against Meta's real login page (no real
-Meta account was used, and nothing was sent to Meta): whether Meta's login
-still goes only through `oculus.com`, `meta.com` and `facebook.com`, whether
-it uses pop-ups (they open in the same window here, which would break a
-pop-up that reports back to its opener), whether `oc_ac_at` is still set on
-`oculus.com` after login, and whether Meta accepts the window (Frame Control
-removes Electron's name from the user agent as a precaution). A real Meta token and Meta's real answers (none was
-available; nothing was sent to Meta), real downloads and their redirects,
-real Quest games installed or tested on a real Frame, and whether the log
-signatures match what real games print in Lepton.

-# Import from my Quest
-
-Move games you own from your own Meta Quest onto the Steam Frame. Plug the
-Quest into your computer by USB; Frame Control copies the game off it with
-adb, checks it can run in Lepton, and installs it on the Frame like any other
-APK, with its own Lepton instance and Steam library entry
-([apks.md](apks.md), [vr-apks.md](vr-apks.md)).
-
-There is no licence-check bypass, and there won't be. A game that uses Meta's
-licence check installs with a warning: on the Frame that check can't reach
-Meta, so the game may quit, hang, or run without online features. See
-[What won't run](#what-wont-run-and-why) below. To install games you own
-straight from Meta instead, without a Quest, see [My Meta library
-(Experimental)](meta-library.md).
-
-## Before you start: developer mode on the Quest
-
-adb only reaches a Quest with developer mode on:
-
-1. Make a free Meta developer organisation at
-   [developers.meta.com](https://developers.meta.com/horizon/) on a **verified**
-   Meta account (Meta asks for a phone number or payment card to verify).
-2. In the Meta Horizon phone app, open the headset's settings and switch
-   **Developer Mode** on. Restart the Quest.
-3. Plug the Quest into the computer that runs Frame Control with a USB cable
-   that carries data (some charging cables don't).
-4. Put the headset on. Accept **Allow USB debugging**, and tick **Always allow
-   from this computer**.
-
-Frame Control uses the adb it already uses for the Frame (an adb you
-installed, else the one it bundles). On Linux, adb also needs permission to
-open the Quest: add a udev rule for Meta's USB vendor id `2833`, for example
-`SUBSYSTEM=="usb", ATTR{idVendor}=="2833", MODE="0660", GROUP="plugdev"`, and
-be in that group. Then unplug and replug.
-
-The Frame's own adb connections (Frame Control's SSH tunnels to Lepton,
-`127.0.0.1:<port>`) are never touched. Only a device that reports itself as
-Oculus or Meta, or a Quest model, counts as a Quest.
-
-## Using it
-
-In the app: **Android → On your Frame → Import from my Quest**. Choose **Look
-for my Quest**, then **Import** next to a game. Tick **Also copy each game's
-files in Android/data** to bring the game's external files too (some games
-keep saves there). Progress shows in the panel; the result and any reason it
-stopped appear in the message log.
-
-A game with game data (an OBB folder, or Android/data when ticked) takes two
-imports, because Android can only take that data while the game's Lepton
-instance is running, and there is no way to start the instance without the
-game. Frame Control never starts the game itself:
-
-1. **Import** installs the game and says it has data to add.
-2. Start the game from the Steam library and leave it on its first screen.
-3. **Import** again. Frame Control sees the game open with the same version,
-   copies the data in, and closes the game. Start it again to play.
-
-A game that quits straight away without its data can't take it this way.
-
-From a terminal:
-
-```sh
-python3 ui/frame_quest.py devices                      # what adb sees, and which is the Quest
-python3 ui/frame_quest.py list                         # apps on the Quest: split or not, OBB and data sizes
-python3 ui/frame_quest.py import com.example.game      # copy one to the Frame
-python3 ui/frame_quest.py import com.example.game --data --serial 1WMHH000XXXXXX
-```
-
-The API is `GET /api/quest` (the Quest, or guidance when there isn't one, and
-its apps) and `POST /api/quest` with
-`{"action": "import", "package": "...", "serial": "...", "data": false}`,
-which returns a background job (`/api/job`) with a stage and percentage.
-
-## What an import does
-
-1. Finds the Quest (`adb devices -l`, then `ro.product.manufacturer` and
-   `ro.product.model`). If none is ready it says why: nothing connected, not
-   authorised yet (the **Allow USB debugging** prompt), no USB permission
-   (Linux), offline, another Android device, or several Quests.
-2. Lists third-party apps (`pm list packages -3`), each with `pm path` (one
-   line is a single APK, several a split APK) and the size of
-   `/sdcard/Android/obb/<package>` and `/sdcard/Android/data/<package>`.
-   Labels aren't shown before import: reading them means copying the APK.
-3. Checks there is room on the computer (the APKs, a merged and a patched copy
-   of them counted uncompressed, the OBB folder and the Android/data folder
-   once, since that is streamed to the Frame), then copies the APK and its splits
-   into a per-user cache folder (`Frame Control/quest-import` under the
-   system's cache folder).
-4. **Checks the APK before anything else is copied**, refusing:
-   - 32-bit-only builds (native code but no `arm64-v8a`);
-   - apps that need an Android newer than Lepton's (API 30);
-   - split APKs Frame Control can't merge (below).
-   Installed with a warning:
-   - games that use Meta's licence check (Meta's Platform SDK,
-     `libovrplatformloader.so`, in the base or any split): "uses Meta's
-     licence check; it may quit, hang, or run without online features on the
-     Frame. Frame Control won't remove the check." Linking the SDK doesn't
-     mean a game enforces the check: Meta's store requirement for it
-     (VRC.Quest.Security.1) has only been *Recommended* since 2021, and what
-     a game does when the check fails is up to the game;
-   - VrApi-only builds (`libvrapi.so`, no OpenXR loader), flagged as for any
-     APK: the Frame has no VrApi, so they may not run.
-5. If the game isn't open on the Frame: installs it through the normal APK
-   install (`frame_android.install`: VR detection, the launcher fix, the
-   OpenXR compatibility layer, artwork), and says whether it has game data
-   to add. An older Quest copy never replaces a newer version on the Frame
-   (compared by version code, which installs now record; for installs made
-   before that, it is read from the installed APK on the Frame) unless you
-   tick **Allow replacing a newer version** (`--allow-downgrade`,
-   `"allowDowngrade": true`). If the installed version can't be read at all,
-   that permission is needed too.
-6. If the game is open on the Frame (the second import): refuses unless
-   Frame Control's install record is for this package, in this package's own
-   instance, at the Quest's exact version code (an open game is never
-   replaced), otherwise copies the OBB folder (and `Android/data` if ticked)
-   from the Quest, waits for Android to have finished booting, copies standard
-   `main|patch.<version>.<package>.obb` files with the existing OBB helper
-   (checked by SHA-256 inside Android, [sidequest.md](sidequest.md#obb-files))
-   once Android's own `dumpsys package` in that instance shows the same
-   package at the same version code,
-   streams the `Android/data` files in as a tar written straight into the SSH
-   transfer, then closes the game so its next start reads them, and checks
-   its instance has stopped; if it hasn't, or the check itself fails (a
-   failed `podman ps` never reads as "stopped"), the result says so. The game
-   is closed whatever happens during the copy, including a local read error
-   or Ctrl-C, and a failed close is reported without hiding the original
-   error. Everything
-   from the second check of the install record (after the pulls, which can
-   be long) to closing the game holds the same lock as installs and removals.
-   Other files in the OBB folder are listed as not copied.
-7. Deletes the cache folder, whether the import worked or not. A folder left
-   by a crash is removed by a later import after six hours.
-
-Only one import runs at a time. If copying game data fails, the game is
-closed and the message says so; start it and import again.
-
-### Split APKs
-
-Lepton runs one APK per instance, so the shared install path now merges a
-split APK into one (`frame_android.install(base, splits=[...])`, or
-`python3 ui/frame_android.py install base.apk split1.apk ...`). Merging copies
-each split's native libraries and assets into the base, drops the base
-manifest's `isSplitRequired` flag, and re-signs with Frame Control's key, as
-the launcher fix already does. Only splits that hold nothing but
-`lib/<abi>/*.so`, `assets/` and their own signature, manifest and an empty
-resource table are merged. Refused, with the reason, before anything reaches
-the Frame: splits with resources (screen density or language), code
-(`classes*.dex`), any other file, a manifest that declares components or
-libraries (`<service>`, `<uses-library>`...), feature splits, and splits of
-another package. The merged files are held in memory while the APK is
-repacked and signed (as for every patched APK), so a merge adds at most
-512 MB per file and 1 GB in all. Each file is read from its raw bytes and
-checked against both of its ZIP headers: the local header must name the same
-file with the same method, sizes and checksum as the central directory (or a
-data descriptor must carry them; ZIP64 sizes are understood), the data must
-end before the next entry, a stored file must be exactly its declared size, a
-compressed one must end exactly at the end of its data with nothing after it,
-and its checksum must match. So a forged header can't truncate a file or fill
-memory. A resource table counts as empty only
-if it defines nothing at all (styles and other complex entries included). A merged, re-signed APK can't update a
-copy signed by the publisher.
-
-## What won't run, and why
-
-- **Games that enforce their Meta store licence.** Many store games link
-  Meta's Platform SDK (`libovrplatformloader.so`), for the licence check and
-  for user ids, achievements, multiplayer, cloud saves or DLC. On the Frame the
-  SDK can't reach Meta's services, which only exist on Meta headsets. A game
-  that enforces the check then quits or hangs; one that doesn't may run
-  without its online features. Frame Control can't tell which from the APK, so
-  it installs these with a warning and **won't remove or work around the
-  check**, and doesn't bundle, call or link to any tool that does. If yours
-  quits, ask the developer for a build without the check, or get the game from
-  Steam or itch.io. Most SideQuest, itch.io and open-source games don't link
-  the SDK.
-- **32-bit games** (Quest 1 era): the Frame runs 64-bit ARM only. Refused.
-- **VrApi-only games**: the Frame has OpenXR, not Meta's older VrApi. They
-  install with a warning, but may not run.
-- **Anything else that needs Meta**: avatars, Quest-only device checks,
-  passthrough and other `XR_FB_*` features SteamVR lacks
-  ([vr-apks.md](vr-apks.md#what-steamvrs-android-runtime-supports-verified)).
-- **Private app data** (`/data/data/<package>`) can't be read over adb without
-  root, so only saves in `Android/data` come across.
-
-What usually works: OpenXR games without Meta's licence check, for example
-open-source and itch.io builds you sideloaded onto the Quest.
-
-Only import games you own, for your own use.
-
-## Evidence and limits
-
-**Verified locally** with a fake adb (`tests/fakeadb.py`, `tests/test_quest.py`):
-device detection (Quest, the Frame's tunnel, the Frame over USB, other
-Android devices, unauthorised, no permissions, offline, none, several),
-package listing and split detection, the refusals and the licence-check warning, the order of copies
-(APK checked before the OBB is copied), the two-step install then data copy
-(the game is never started by Frame Control, never replaced while open, and
-closed after its data is copied), split merging and signing, the split
-refusals and size limits (including a forged zip bomb), the space estimate,
-and cache clean-up after success and failure.
-
-**Not verified:** a real Quest (none was available), Quest system apps in
-`pm list packages -3`, real split APKs from the Meta Store, OBB and
-`Android/data` writes into a running Lepton instance on a real Frame
-(the OBB helper itself is also unverified there), whether games stay open
-without their OBB long enough for the second import, and the Linux udev rule.
-Large games are copied into memory while being merged or patched, as every
-patched APK already is.
