MaxsTechReview 7d149acb00 fix: only start SteamVR for VR-only games from Steam's library (#1076) 
Games that merely support VR (No Man's Sky) were held at Play while
DroidDeck downloaded and started SteamVR, so they always opened in VR.
They now launch normally; VR-only games still wait for SteamVR.

MaxsTechReview 69c88aa344 feat: fetch Proton, FEX and the runtimes automatically, and make Linux games run under FEX (#1045) 
* fix: x86 Linux games that also ship for Windows run under Proton again

Since #749 the live compatibility helper treated every installed game with
both Windows and x86 Linux builds as a user's native choice, because the
client reports an empty tool for unmapped games. Those games were left on
the Steam Linux Runtime, which cannot start them here (bwrap fails, or FEX
looks for a RootFS that is not shipped), so Valheim, Moonlighter, Half-Life 2,
TF2 and others exited within seconds.

- An unmapped game the helper never managed now gets the default Proton.
  Clearing a mapping the helper set is still kept as a native choice.
- Native choices are stored under "native_choices". The old "native" list
  also held games nobody picked, so it is dropped.

* feat: Linux builds run under FEX by default, with the runtimes fetched automatically

- Steam fetches Proton, FEX, Steam Linux Runtime 3.0 and 4.0 on the first start and keeps them updated instead of leaving them pending.
- Games that ship a Linux build go to FEX once it can run them; Windows-only games and installed Windows builds keep the Proton default.
- FEX runs games on a combined x86 runtime with the newer glibc and libstdc++ the GL and Vulkan thunks need.
- Vulkan display extensions the driver cannot handle are hidden in front of the thunk, without an audit module.
- Mono's incremental garbage collector is turned off under FEX, which stops Unity games crashing.
- x86 Steamworks finds the x86 steamclient.
- 32-bit games read the virtual controller.

* fix: controllers work in Linux Unity games such as Valheim

Joystick ioctls on an event node now fail with EINVAL like the kernel's evdev, so the SDL2 that Unity embeds reads the pad's real ID instead of ignoring it as 0000:0000.

* test: skip the switch script test without node, and the ring tests without gcc

* fix: games with a Linux build keep the Proton default

The Windows build often runs better, so titles that ship both builds stay on the default Proton again. Users can still pick FEX for one, and that choice is kept. Linux-only titles still go to FEX.

* fix: unmapped dual-platform games get Proton even when config.vdf cannot be read

 		219548f4b6 Add app-wide 3DoF for VITURE, RayNeo and XREAL glasses and 6DoF for Luma Ultra (#1035) 
* Add VITURE glasses support: hardware control, 3D, head tracking

Glasses get their own controller over the MCU (permission, 120 Hz default, brightness, volume, sunblock, 2D/3D) and the game moves onto them when plugged in. The IMU drives Cardboard head tracking and the SteamVR driver. 3D falls back to one eye's view on phones that can't send the 3840x1080 signal. Options open from a glasses button in game and on the Steam page.

* Drop the glasses settings like Steam's: Play-style button, Settings lip, tabs

* Hang the glasses Settings lip over the top of the button

* Space glasses MCU commands so the IMU rate sticks, fit fixed resolutions to the glasses

* Keep Steam alive with SteamVR registered, run SteamVR at the glasses' rate, keep the glasses lip on top

* Fit VR games on the glasses: full view, seated origin at the head, pad hands reach with the d-pad

* Let the pad hands reach a metre out so buttons with deep colliders press

* Show every VR frame in order at 120 fps: wait for SteamVR's GPU work, present only finished copies, skip the grace on idle shared counters

* Glasses: SteamVR starts and stops with them, closer view with a field of view setting, Recenter on the pad

* Glasses: SteamVR field of view defaults to 90°

* VR pad hands: sticks move and aim the hands, left stick click switches the sticks to the game, d-pad pulls a held hand

* Glasses: Play SteamVR beside the glasses button instead of starting SteamVR with them, pad hands drawn as Index controllers and off while other VR controllers are connected, glasses sheet tabs sized like Steam's

* Track glasses mode, refresh-aware glasses window, align Play SteamVR with Play Steam

* Fix 3D on the glasses: full-res SteamVR presenter, revert VR 3D at session end, coalesce vsync ticks, no session restart after end

* Address review: glasses output after installs and session end, VR revert retry, display fallback, presenter swapchain retry, agent hex checks, drawer bumpers, glasses translations, docs

* Harden VITURE stereo negotiation and output refresh tracking

* Localize stereo recovery feedback and record Astra reconnect tests

* Improve test failure diagnostics and refresh Astra firmware findings

* Handle VITURE docks separately and reject truncated USB frames

* Glasses: remember a 3D fallback per model, docks as display only, VR timing fixes

- A 3D attempt that ends at the 640x480 fallback is remembered for that glasses
  model, so Play SteamVR no longer blacks out the glasses after every restart;
  Retry clears it and "3D for VR games" stays reachable
- A VITURE Mobile Dock on its own no longer counts as glasses; through a dock
  Play SteamVR is hidden and the sheet shows the output and why there is no control
- HDR is probed on the glasses when the session starts there
- Glasses frames with a mismatched checksum are marked in the status frame log
- SteamVR layer and driver vblank counters stay monotonic across refresh changes;
  one-eye render scale applies from activation and on mono/3D switches
- Compositor binds announce the refresh clients were last told; the presenter
  retries a failed first swapchain
- Dead strings and helpers removed; docs updated

  the old "coming soon" behaviour; align with the current English text.
- summary_remove_game: was still English in all four locales.

Machine-assisted translation; native-speaker review is welcome.

* fix: a failed cloud save recovery no longer ends the app (#846)

The cloud-recovery thread started at every app start had nothing to
catch an error, so one went to CrashHandler, which halts the process
with status 2. In unit tests the thread can outlive the test that
started it, fail on the torn-down preferences, and take the whole test
run down. The error is now logged and the thread ends.

* fix: an interrupted Linux runtime download resumes instead of starting again (#847)

* fix: an interrupted Linux runtime download resumes instead of starting again

installOnce() asked the downloader to resume but always deleted the archive in its finally block, so the next attempt began at zero. The archive is now named after the release version and checksum, a failed download keeps what it fetched, and archives of other releases (and the old fixed name) are removed. A checksum or extraction failure still deletes the file.

* test: Downloader resumes a cut-off download from the bytes it kept

Starts a socket server that promises the whole file, hangs up part way and then answers a Range request, and checks that the second downloadFile call resumes with the right offset and ends with identical bytes.

* fix: a resumed download discards a 206 that does not start where the kept bytes end

Downloader appended every 206 response to the partial file without
looking at Content-Range. A server or proxy that answers a Range request
with a different offset would leave a corrupt file. Check that the range
starts at the kept length; otherwise delete the partial file and start
again without a Range header.

Adds a test with a server that answers the Range request from offset 0.

* fix: droiddeckctl reaches variant-package builds (recover #842) (#854)

fix: droiddeckctl reaches builds shipped under a variant package

The provider authority and the start Activity's component were fixed to
com.droiddeck.launcher, so droiddeckctl could not talk to the antutu,
ludashi or pubg builds from tools/release/variants.txt. DROIDDECK_PACKAGE
now picks the package; the Activity's class name stays the same in every
variant.

* feat: droiddeckctl reports on-screen pacing (recover #843) (#855)

feat: droiddeckctl pacing reports the frames that reached the screen

Reads SurfaceFlinger's timestats for the game's layer (or the session's
SurfaceView) over a capture: frames on screen, fps on screen, the
present-to-present histogram and how many intervals were off the usual
cadence. Records split by a refresh-rate change are summed. A game's own fps
counter counts frames handed over, so it can't show dropped or doubled frames.

* fix: Steam can restart more than twice in a session (#754)

* fix: Steam can restart more than twice in a session

Every exit 42 counted toward the cap that stops an update which will
not install, and the count was never cleared, so the third restart of
a session ended it however far apart they were. A client that ran for
a minute before asking is not that loop: the count starts again.

* fix: measure the client's run time as it exits

The time spent collecting logs and checking FEX after the client exits
counted toward its run, so a slow cleanup could make a quick exit 42
look like a long one and clear the count.

* fix: the front end keeps its page when the Fold is folded or unfolded (#832)

* fix: the front end keeps its page when the Fold is folded or unfolded

MainActivity, FileManagerActivity, FilePickerActivity and StoreLoginActivity did not declare the screen-size configuration changes, so folding or unfolding a foldable recreated them and dropped their in-memory state. They now handle orientation, screenSize, screenLayout, smallestScreenSize and density themselves, like SessionActivity already does. uiMode is left out on purpose.

* fix: store login keeps rebuilding its toolbar when the display density changes

StoreLoginActivity builds its toolbar in code with dp-to-pixel values taken at creation time and has no onConfigurationChanged. It no longer declares density in configChanges, so a density change recreates it as before this PR. Size and layout changes are still handled in place.

* l10n: translate the 184 strings added since #284 (zh-CN/HK/TW, ja)

The stores, cloud saves, Windows components, Steam touch, desktop
removal and background-downloads strings landed after #284's
translation snapshot, so every one of them fell back to English.
Translate all 184 into Simplified Chinese, Traditional Chinese
(Taiwan and Hong Kong) and Japanese, keeping each locale file's own
vocabulary (工作階段/會話, 解除安裝/卸載, 元件/組件, 設定).

Also fix four Hong Kong strings that kept the simplified 着色器.

* l10n(zh): fix stale and ambiguous strings found in review

Severe: summary_remove_game was untranslated English in all three
files; mode_added_art_hint, wincomp_installers_note and
wincomp_needs_installer still described the pre-#480/#492 English.

Also: distinguish the Setup wizard from Android system settings in
zh-HK/zh-TW (初始設定 / 系統設定 / Android 設定), unify library as
收藏庫, component as 組件 in zh-HK, session as 會話 in zh-HK, account
as 帳戶 in zh-HK, Trending as 趋势/趨勢, Forget as 清除, reword the
re-applied-at-launch, action-failed and already-in-Games strings, and
play as 執行/開啟遊戲 in zh-TW/zh-HK.

* Glasses: keep a pending 2D restore and the SteamVR recovery offer, show Play SteamVR only with a picture

* Translate the glasses calibration, XREAL and SteamVR recovery strings

* SteamVR recovery: give a finished teardown time to collect logs before restarting

* Credit the projects the XR glasses support builds on

* Joy-Cons: SteamVR hands from their gyro while SteamVR runs, one combined pad otherwise

* Add experimental Luma tracking and stabilize SteamVR launches

Add native Luma Ultra spatial tracking, optical controllers, and stereo
calibration with DroidDeck styling, imperial/metric measurements, and
pending recenter recovery. Include the pinned hand model and calibration board.

Keep live guest and SDK files outside Android's evictable cache. Filter the
Adreno 840 sysmem override in the shared SteamVR helper, serialize timeline
mirroring, retain invalid optical controllers without event floods, and
prevent an unprivileged scheduling fallback from lowering compositor RTTIME.

Validation: latest APK build and runtime freshness checks pass; 247 affected
glasses/calibration tests pass. Native VR, helper, and packaging regressions
pass. Two earlier phone library launches sustained 60 fps for 308 and 188
seconds without recovery or restart. The newer calibration APK is installed
and checksum-verified; calibrated-hand and sustained gameplay acceptance
remain pending. One existing Android test requires Windows symlink privileges.

* Headsets: settings badge on Play SteamVR instead of a top-right button, both shown only once connected

* Hand tracking: camera-tracked Joy-Cons and bare hands in SteamVR, drawn as white gloves

- Joy-Con movement from the accelerometer (report reordering, per-Joy-Con calibration, zero-velocity updates)
- MediaPipe pose and hand landmarks from the device camera, placement check, per-hand Kalman filter with the Joy-Con
- No controller connected: bare camera hands with Quest-style gestures, 1€ filtered, rendered as a white glove model built from a distance field
- SteamVR safe mode cleared before each start so one crash no longer blocks the driver

* Improve Luma Ultra tracking and isolate device-specific controls

Refine stereo hand and Joy-Con tracking, gesture release, calibration,
recovery UI, diagnostics, display modes, and compositor handling.
Keep Ultra controls and input routing behind a live SDK-confirmed Carina
connection; clear retained spatial mode when other glasses connect.
Add optional UVC transport with pinned dependencies and packaged notices.

Validation: 456 Android tests, ARM64 VR build and native regressions,
47 tooling tests, SDK/UVC-enabled and disabled builds, and 150 packaged
runtime checksums. Two shader compilation tests skipped because the
compiler is unavailable. Hardware interaction gates remain experimental.

* Delay Luma Ultra 6DoF until SteamVR settles

Suspend spatial SDK startup while SteamVR launches, then restore it two seconds
after RUNNING is confirmed. Preserve saved tracking preferences and automatically
recenter same-device restoration, including cancellation and early stop.

Discard superseded launch requests and status replies after session teardown.

Validation: 128 focused JVM tests passed on the isolated commit snapshot; 129
passed with the current local hand-tracking work. Debug build and runtime checks
passed, and the reviewed APK was installed and hash-verified on the phone.

* Clarify glasses and phone camera tracking options

Separate Luma Ultra camera controls from phone-camera tracking so the two
hand-tracking switches have clear sources. Label bare-hand controllers and
Joy-Con position tracking explicitly, explain physical Joy-Con inputs and
camera priority, and update the camera prompt and calibration guidance.

Use fresh phone section and toggle labels so existing translations do not
hide the distinction. Preserve tracking behavior and saved preferences.

Validation: 39 existing UI tests, debug build, and packaged runtime verification
passed. Reviewed changes and installed the APK on the connected phone.

* Fix tracking handoff and shared runtime regressions

Release spatial ownership and controller overrides when output returns to the phone. Preserve USB-loss recovery, keep Vulkan submissions asynchronous, clean persistent guest scratch on runtime removal, and clarify the 6DoF head-tracking control.

* Apply smart-glasses virtual screens across DroidDeck menus

* Finalize Luma hand baseline and document smart-glasses support

Keep raw grayscale-to-RGB Full hand inference, wrist-only Joy-Con reconstruction, bounded visual holds, and the dead-zone rollback. Retain opt-in steady aim, recenter controls, reproducible Lite models, and the JPEG-padding fix.

Remove unsuccessful benchmark-only and USB transport experiments. Document the cross-brand 3DoF matrix, Luma Ultra 6DoF, SDK requirements, and app-wide screen behavior.

* Fix executable permission for SteamVR launcher

* Address hand tracking and VR review findings

* Bound stereo recovery test image comparison memory

* Localize smart-glasses setup and tracking diagnostics

Move calibration controls, status messages, validation errors, distance labels,
and printed-board instructions into Android string resources. Add and update
machine-assisted translations in all 32 supported non-English locale catalogs,
with corrections for recentering, hand tracking, product names, and measurements.

Keep print instructions within the page using text layout that supports wrapping
and right-to-left text. Correct the Lite model toggle description to reflect its
Lite palm detector and Lite landmark model.

Add locale coverage, format-argument, line-break, and measurement checks, plus
French and Arabic calibration UI tests. Preserve tracking calculations and the
shared runtime storage behavior.

Validation: Android resource and Kotlin compilation; 3 localization checks;
68 focused tests; 1,597 JVM tests at a 512 MB heap; French and Arabic UI renders.

* Correct smart-glasses translations from PR review

Fix the 42 localization findings covering hand and head terminology, disabled states, calibration dimensions, camera visibility, capture rejection, and menu references. Correct the repeated capture-error ambiguity in related locales and clarify its English source. Keep Romanian setup instructions consistent with the existing informal voice.

Extend localization measurement validation to distance hints and retry guidance. Verify the recovery screen's palette-dependent text color with one row-sized pixel buffer and guaranteed bitmap cleanup.

Validation: Android resource and Kotlin compilation; 3 localization checks across all supported locales; 68 focused JVM tests at a 512 MB heap.

* Work around SteamVR device loss with Adreno 840 Turnip v0.2.0

* Withdraw ineffective SteamVR flushall workaround

The412Banner cf6cf168b0 feat: x86-64 client follows DroidDeck-Components' fex.json; fuller x86-64 session logs (#1053) 
FEX builds can reach devices without an app release: while the x86-64
client is selected the app reads DroidDeck-Components' fex.json (directly,
on its own thread, not in Offline Mode) and a session passes that build to
droiddeck-steam-x64, which installs it only once its sha256 matches and its
programs load, keeping the replaced files aside until the installed copy
loads too; it keeps a working installed build otherwise and falls back to
the build it pins. FEX is built and published by Components' build-fex.yml
on its single fex release; this repository's build-fex.yml only checks the
build. x86-64 session logs name the FEX build and its source, the rootfs and
the client's builds, report the rootfs download in tenths, and say in one
line when the web helper's GPU process keeps exiting, with x86 glxinfo and
vulkaninfo through FEX. Settings shows the FEX build installed.

The412Banner 7d21ba2233 fix: x86-64 Steam client fails without the KDE desktop (FEX r5 bundles libxxhash) (#1050) 
FEX r4 links libxxhash, which the Linux runtime does not ship; devices
without the KDE desktop package (where the library came from) exited 127
at the x86-64 client's first FEX call. FEX r5 bundles it beside libFEXCore

The412Banner ae94d9db54 feat: optional x86-64 Steam client (Valve's Linux client under FEX) beside the arm64 one (#152) 
An opt-in second Steam client (Steam settings, Steam client: x86-64): Valve's
x86-64 Linux client, unchanged, runs under FEX in its own home with its own
game library and the same sign-in. Linux builds run directly, so titles such
as Team Fortress 2 and Half-Life use their Linux versions; Windows games use
DroidDeck-Proton as on arm64. The arm64 client stays the default.

- droiddeck-steam-x64: FEX and the x86-64 rootfs from DroidDeck-Components
  (sha256-pinned), client install and sync from Valve's CDN, sign-in shared
  with the arm64 client, its web helper on the GPU (ANGLE GL over FEX's GL
  thunk, zink, Turnip), Proton wrappers for the arm64 client's tools,
  DroidDeck direct for Linux builds, SD-card library (x86-64/ beside the
  arm64 one), repair.
- FEX 2610 built by build-fex.yml with thunks and three patches: an openat2
  fallback without openat2 (proot), newer-clang thunkgen, MAP_32BIT
  exhaustion returning ENOMEM. libblsession resolves RESOLVE_IN_ROOT paths
  inside the root.
- Session: x86-64 gating, shortcuts and compatibility tools per client,
  logs from the client that ran.
- App: client setting with the FEX version, an x86-64 chip on the Games
  header, the active client's library, art, storage, downloads, repair,
  Offline Mode, Decky, desktop mode, optional VAC diagnostics; per-client
  state for art, the content log, repair and leftovers.
- Strings in every locale.
- Review fixes: the library cache is saved only by the newest scan; an
  abandoned session's Steam logs come from the client it recorded; distinct
  VAC console names; FEXInterpreter in CPU pinning; clearer VAC hint in
  pl, ru, uk, cs and bg.

MaxsTechReview 97f976ef6c feat: Epic Games Launcher for Linux (#928) 
* feat: Epic Games Launcher for Linux

Install Epic's official Linux launcher (EGLv2) from Epic's CDN with Valve's
Steam Runtime 4 and run it under FEX, signed in with the linked Epic account.
Epic games launch through a hidden launcher instance so they get the
launcher's own arguments, with the exchange-code launch as the fallback, and
DroidDeck installs show up in the launcher as installed.

In the launcher, touch scrolls like a phone app and the gamepad drives the UI:
D-pad and left stick move the selection, A opens, B goes back, the right stick
and triggers scroll proportionally, X opens the options menu, Y the keyboard
and LB/RB switch tabs.

Install Epic's official Linux launcher (EGLv2) from Epic's CDN with Valve's

D-pad and left stick move the selection, A opens, B goes back, the right stick
and triggers scroll proportionally, X opens the options menu, Y the keyboard
and LB/RB switch tabs.

* Route Epic games through Steam, import launcher installs, offer the second library

- Every Epic launch goes Steam -> Epic Games Launcher -> game; Play inside the open launcher hands the game to Steam
- Games installed from inside the launcher get a Games-tab entry and launch through Steam; the launcher installs to the last Stores target
- Stores install picker offers the Steam second library, with side-by-side choices
- uruntime xattr-only failures no longer fail the launcher unpack (app-extract)

* Hand launcher Play and Steam links to Steam, wait for FEX on first run

Play on a game the launcher just installed is matched to its install
record and handed to Steam. Steam games listed in the launcher open
steam://rungameid links, which now start the game in a Steam session.
Opening the launcher before Steam has downloaded FEX asks Steam for it
and starts Steam instead of failing with no-fex.

* Address review: FEX check, play-in-Steam action, touch route thread, scroll scale

fexReady needs a FEX binary in Steam's FEX tool, not just its folder.
The play-in-Steam action stays until the link is handled, so Run Steam
at startup can't start a session first. The pad touch route reads the
mouse mode without side effects off the main thread and posts the pad
update there. Vertical scroll uses the output height. A status-2 unpack
counts only when AppRun is there. The xdg-open command is tested
end to end for Steam links.

* Open the launcher through Steam, recover dropped shortcuts, sign out of both

The Epic Games Launcher now runs as its own Steam shortcut, so opening
it starts Steam, which opens the launcher, and Play inside it goes to
the running Steam.

Steam dropped a running shortcut from its library when the game exited
after a sleep/wake replay or a server re-logon, and launching it then
waited forever at ShowInterstitials. login1 only replays sleep/wake
when Steam is asleep. The session restarts Steam when a requested
shortcut is missing, and when a game exits with its shortcut gone and
nothing else runs.

Resuming after a long pause no longer reports failure while traced
processes are still waking, so "Steam is paused" goes away on the first
tap.

Signing out of the launcher signs DroidDeck's Epic store out, and
signing out in DroidDeck restarts the launcher signed out and clears
the Epic web cookies.

* Address review: one session-switch poll, Epic setup can't block a session

A new switch confirmation replaces the pending poll instead of adding a
second one that could start the session again. Epic library sync and
install-folder setup at session start are each guarded, so a bad
preference no longer stops the guest from launching.

* Uninstall the Epic Games Launcher from the Games tab

An Uninstall button next to Launch asks first, closes a running
session, and removes the launcher and its runtime. The launcher's
sign-in and install records stay, so its games keep their Games-tab
entries and a reinstall comes back signed in. Its Steam shortcut goes
away on the next Steam start.

* Address review: uninstall only after the session has ended

The launcher's files are removed only once the session is not running
and its phase has ended; a shutdown still in progress after the wait
reports failure instead. The confirmation reads the session state from
the front-end state.

* Find FEX that Steam installed on the second library

Steam's tools on a second library live in DroidDeck's private copy,
which the session binds over the library. The launcher's FEX check
only looked on the shared storage, so with FEX there it always asked
Steam for FEX and only Steam opened. It now checks the private copy
too.

* Start games without Steam, per-game Settings menu with Wine sync

"Start without Steam" now really leaves the Steam client out: the game
runs in its own Proton/FEX through droiddeck-proton-run in a run
session, and the Epic Games Launcher opens on its own with its games
playing in it. Run sessions for these games are not pinned to the big
cores and get DirectAudio and the added-games list like Steam.

The Games tab card is now "Settings", titled "<game> Settings": Start
without Steam, FEX preset, Wine sync (ntsync, fsync, esync, wineserver
or the app default) and Default, which puts everything changed for the
game back to the app's settings. The app-wide Wine sync choice is shown
in the Steam settings Session tab.

* Address review: uninstall guard, routed games, shortcut matching

Opening or reinstalling the Epic Games Launcher waits while it is being
uninstalled. Added games that are Steam installs keep their Start
without Steam setting under their Steam app id and start as that Steam
game. Live shortcut lookups wait for Steam's library to load and match
a same-name shortcut by its executable, so no duplicate is added. The
session treats the open launcher as itself even when it could not tell
its Steam app id.

* Address review: drop a queued launcher switch when it is uninstalled

A confirmed switch to the Epic Games Launcher that is still waiting for
the old session to end is cancelled when the launcher is uninstalled,
and never starts while the uninstall runs. The launcher id test sets
its environment for its own runs only.

 		83eda433c8 Add VITURE XR controls, head tracking, and SteamVR (#732) 
* Add VITURE glasses support: hardware control, 3D, head tracking

Glasses get their own controller over the MCU (permission, 120 Hz default, brightness, volume, sunblock, 2D/3D) and the game moves onto them when plugged in. The IMU drives Cardboard head tracking and the SteamVR driver. 3D falls back to one eye's view on phones that can't send the 3840x1080 signal. Options open from a glasses button in game and on the Steam page.

* Drop the glasses settings like Steam's: Play-style button, Settings lip, tabs

* Hang the glasses Settings lip over the top of the button

* Space glasses MCU commands so the IMU rate sticks, fit fixed resolutions to the glasses

* Keep Steam alive with SteamVR registered, run SteamVR at the glasses' rate, keep the glasses lip on top

* Fit VR games on the glasses: full view, seated origin at the head, pad hands reach with the d-pad

* Let the pad hands reach a metre out so buttons with deep colliders press

* Show every VR frame in order at 120 fps: wait for SteamVR's GPU work, present only finished copies, skip the grace on idle shared counters

* Glasses: SteamVR starts and stops with them, closer view with a field of view setting, Recenter on the pad

* Glasses: SteamVR field of view defaults to 90°

* VR pad hands: sticks move and aim the hands, left stick click switches the sticks to the game, d-pad pulls a held hand

* Glasses: Play SteamVR beside the glasses button instead of starting SteamVR with them, pad hands drawn as Index controllers and off while other VR controllers are connected, glasses sheet tabs sized like Steam's

* Track glasses mode, refresh-aware glasses window, align Play SteamVR with Play Steam

* Fix 3D on the glasses: full-res SteamVR presenter, revert VR 3D at session end, coalesce vsync ticks, no session restart after end

* Address review: glasses output after installs and session end, VR revert retry, display fallback, presenter swapchain retry, agent hex checks, drawer bumpers, glasses translations, docs

* Harden VITURE stereo negotiation and output refresh tracking

* Localize stereo recovery feedback and record Astra reconnect tests

* Improve test failure diagnostics and refresh Astra firmware findings

* Handle VITURE docks separately and reject truncated USB frames

* Glasses: remember a 3D fallback per model, docks as display only, VR timing fixes

- A 3D attempt that ends at the 640x480 fallback is remembered for that glasses
  model, so Play SteamVR no longer blacks out the glasses after every restart;
  Retry clears it and "3D for VR games" stays reachable
- A VITURE Mobile Dock on its own no longer counts as glasses; through a dock
  Play SteamVR is hidden and the sheet shows the output and why there is no control
- HDR is probed on the glasses when the session starts there
- Glasses frames with a mismatched checksum are marked in the status frame log
- SteamVR layer and driver vblank counters stay monotonic across refresh changes;
  one-eye render scale applies from activation and on mono/3D switches
- Compositor binds announce the refresh clients were last told; the presenter
  retries a failed first swapchain
- Dead strings and helpers removed; docs updated

* fix: a failed cloud save recovery no longer ends the app (#846)

The cloud-recovery thread started at every app start had nothing to
catch an error, so one went to CrashHandler, which halts the process
with status 2. In unit tests the thread can outlive the test that
started it, fail on the torn-down preferences, and take the whole test
run down. The error is now logged and the thread ends.

* fix: an interrupted Linux runtime download resumes instead of starting again (#847)

* fix: an interrupted Linux runtime download resumes instead of starting again

installOnce() asked the downloader to resume but always deleted the archive in its finally block, so the next attempt began at zero. The archive is now named after the release version and checksum, a failed download keeps what it fetched, and archives of other releases (and the old fixed name) are removed. A checksum or extraction failure still deletes the file.

* test: Downloader resumes a cut-off download from the bytes it kept

Starts a socket server that promises the whole file, hangs up part way and then answers a Range request, and checks that the second downloadFile call resumes with the right offset and ends with identical bytes.

* fix: a resumed download discards a 206 that does not start where the kept bytes end

Downloader appended every 206 response to the partial file without
looking at Content-Range. A server or proxy that answers a Range request
with a different offset would leave a corrupt file. Check that the range
starts at the kept length; otherwise delete the partial file and start
again without a Range header.

Adds a test with a server that answers the Range request from offset 0.

* feat: droiddeckctl reports on-screen pacing (recover #843) (#855)

feat: droiddeckctl pacing reports the frames that reached the screen

Reads SurfaceFlinger's timestats for the game's layer (or the session's
SurfaceView) over a capture: frames on screen, fps on screen, the
present-to-present histogram and how many intervals were off the usual
cadence. Records split by a refresh-rate change are summed. A game's own fps
counter counts frames handed over, so it can't show dropped or doubled frames.

* fix: Steam can restart more than twice in a session (#754)

* fix: Steam can restart more than twice in a session

Every exit 42 counted toward the cap that stops an update which will
not install, and the count was never cleared, so the third restart of
a session ended it however far apart they were. A client that ran for
a minute before asking is not that loop: the count starts again.

* fix: measure the client's run time as it exits

The time spent collecting logs and checking FEX after the client exits
counted toward its run, so a slow cleanup could make a quick exit 42
look like a long one and clear the count.

* fix: the front end keeps its page when the Fold is folded or unfolded

MainActivity, FileManagerActivity, FilePickerActivity and StoreLoginActivity did not declare the screen-size configuration changes, so folding or unfolding a foldable recreated them and dropped their in-memory state. They now handle orientation, screenSize, screenLayout, smallestScreenSize and density themselves, like SessionActivity already does. uiMode is left out on purpose.

* fix: store login keeps rebuilding its toolbar when the display density changes

StoreLoginActivity builds its toolbar in code with dp-to-pixel values taken at creation time and has no onConfigurationChanged. It no longer declares density in configChanges, so a density change recreates it as before this PR. Size and layout changes are still handled in place.

The stores, cloud saves, Windows components, Steam touch, desktop

The cold-launch gate waited once for 45 s and, on a timeout, held the
launch URL for good. A library that loads slower than that (or a client
still at the sign-in screen) left the requested game never started, with
nothing on screen. Retry the wait up to 40 times, 45 s each, and launch
as soon as the overview exists. The no-overview case still does not
forward the CGameID.

 		39c8a0fe8c fix: Steam can restart more than twice in a session (#754) 
* fix: Steam can restart more than twice in a session

Every exit 42 counted toward the cap that stops an update which will
not install, and the count was never cleared, so the third restart of
a session ended it however far apart they were. A client that ran for
a minute before asking is not that loop: the count starts again.

* fix: measure the client's run time as it exits

The time spent collecting logs and checking FEX after the client exits
counted toward its run, so a slow cleanup could make a quick exit 42
look like a long one and clear the count.

Tjebbe Kerstens 913806f169 fix: seed redist markers again when the registry lost them (#793) 
* fix: redist markers a replaced registry lost are seeded again

droiddeck-seed-redists recorded what it seeded in .droiddeck-redists and
trusted that record from then on. A Proton update replaces its
default_pfx system.reg but leaves our record beside it, and every new
prefix copies both, so new games got a record of markers their registry
never had: Steam then ran their install scripts for real. Batman: Arkham
City's AMD Dual-Core Optimizer installer hangs there, leaving the game
on "Running install script" on every launch.

Each recorded marker is now looked up in the registry, in both views
where both were written, and seeded again when it is gone; a record of
markers nobody wants any more is rewritten without them.

* Check every VC runtime architecture before keeping the vcrt marker

vcrt writes Installed for x86, x64 and arm64 in both registry views, but
present() only looked at x86. If only an x64 or arm64 value was gone the
runtime would not be seeded again. Require all six values and test the
loss of the arm64 Wow6432Node one.

Tjebbe Kerstens 7b018e6c42 fix: Batman: Arkham City starts with full x87 precision under FEX (#792) 
Arkham City (BatmanAC.exe) stopped with Unreal's "Fatal error!" about
1.5 s after start: an access violation in BatmanAC.exe right after
steam.dll loads. The game leans on x87 and needs full precision under
FEX (FEX wiki), while the default FEX preset sets
FEX_X87REDUCEDPRECISION=1. Engine fixes sit above the shared preset and
below the player's own game profile, so a fix keyed on BatmanAC.exe
beside the started exe (BatmanAC.exe or BmLauncher.exe) restores
x87 precision for this game only. Arkham Asylum, which shares
BmLauncher.exe but not BatmanAC.exe, keeps the preset.

William AllenandClaude Opus 5.5 c035351b4f fix: read the replaced listing's watch descriptor before detach can free it (#685) 
install() replaces an existing cache entry by calling detach(old), which
destroys the listing when no reader holds it, and then reads old->wd to
decide whether to release the watch. When the old listing has no readers,
that read happens after the free.

Two threads that enumerate the same uncached directory at the same time
reach this path: both build a listing, the first installs an entry with
no readers, and the second replaces it.

Save the watch descriptor before detaching, as drop() already does.

MaxsTechReviewandxXJsonDeruloXx f0c52c273b Add opt-in zRAM compression for the Steam client while a game runs (#442) 
* Add opt-in zRAM compression for the Steam client while a game runs

A "zRAM compression" toggle under Steam > Settings > Session, below
"Keep downloads running". Off by default, kept once set, and disabled
on devices without swap or with a kernel older than 5.4.

When on, the session watches for Steam's reaper. 20 s into a game the
client and its web helpers page their private anonymous memory out to
the device's zram with MADV_PAGEOUT from inside their own process
(libblsession zram.c, SIGURG), again every 5 minutes, and read every
swapped page back once the game exits. No root is needed: only a
process itself may do this without CAP_SYS_NICE. With the toggle off
nothing is installed or started.

RedMagic NP06J, Palworld: Steam's resident memory fell from ~1.7 GB to
~1.1 GB with ~560 MB in zram, available memory during play rose by
~0.5-0.8 GB, and ~2 MB was left in zram after the read-back.

* Turn zRAM compression on by default below 12 GB of RAM

Until the toggle is changed, it follows the device: on when the kernel
supports it and the device has less than 12 GB of RAM, read from the
advertised memory size on Android 14+ and from total memory before that.
Turning it off is kept.

The412Banner 40bca96db5 feat: Start without Steam, a per-game switch for games that close right away 
A game that closes as soon as it starts can be tripped by Proton's Steam
setup (steam.exe, the Steam registry entries, the Steam client bridge).
The Games page of the session drawer gets a per-game Start without Steam
switch, stored as DROIDDECK_NO_STEAM=1 in the game's environment and listed
in its profile summary.

droiddeck-game-env acts on it for a game launch only: a Proton with umu's
launch (GE-Proton, Proton-CachyOS, DroidDeck-Proton) gets UMU_ID, so it
runs umu.exe in place of steam.exe and still sets up the prefix; a Steam
game keeps its protonfixes under its own id, an added game gets 0. Any
other Proton runs the game straight in the prefix (runinprefix).

MaxsTechReview 3c2878cc52 Red Dead Redemption 2: launches again, no screensaver over games, hidden launcher held to one core, /tmp cleaned (#585) 
* fix: Red Dead Redemption 2 launches again, its Vulkan runtime installer is left to run

droiddeck-seed-redists marked every process in every game's install script
as already run, Red Dead Redemption 2's VulkanRT-1.1.108.0 installer
included. Steam's compat config for the game says nativevulkanloader, so
Proton loads vulkan-1.dll native only, and Khronos' loader is in the prefix
only once that installer has run. Without it the Rockstar launcher starts
RDR2.exe and it exits with STATUS_DLL_NOT_FOUND (0xc0000135) before it
opens a window.

A Vulkan runtime installer is now left out of the seeding, and a marker an
earlier seeding wrote for one comes out of each prefix and Proton template
once (dates kept), so the client runs the installer on the next launch.
The installer finishes in a few seconds under FEX.

* fix: Steam's screensaver no longer covers a running game

The client's defaults show screensavers while a game runs, after 300 s on
AC power without a button press - and a held stick or trigger is no press.
Red Dead Redemption 2's intro runs longer than that: the slideshow covered
the game, and the button that woke it reached the game too (B asked to
quit to the desktop). Customization/Screensaver/WhileInGame is seeded "0"
in config.vdf once, like the UI scale and native resolution, so turning it
back on in Settings stays the user's choice.

On the RedMagic: 18 minutes from the last button press through the intro
and riding, focus never left the game and no screensaver was created.

* fix: Rockstar's hidden launcher no longer takes cores from its game

The Rockstar Games Launcher keeps drawing its Chromium interface
(SocialClubHelper.exe: renderers, and a GPU process compositing through
DXVK) for as long as the game runs, hidden behind it - and Wine passes
Chromium's priorities on, so those threads ran above the game's (the GPU
process at nice -10), across every core. With Red Dead Redemption 2 in
front that was 1.3 to 2.5 cores under FEX for a page nobody sees.

droiddeck-launcher-cores follows gamescope's focus from the agent's
focus.json: while a game window has it, every SocialClubHelper thread runs
on the last core of the slowest cluster at nice 19; when the launcher's own
window has focus again each thread gets its own mask and priority back
(also on exit). Stopping the helpers would not hold - proot resumes a
stopped tracee. Started for Steam sessions; BL_LAUNCHER_CORES=0 turns it off.

RedMagic, RDR2 all Low, riding at the thermal limit, same spot and session:
released 46.5 fps, 1% low 27.5, p99 31.8 ms, CPU 89%, 2200 MHz;
held 48.7 fps, 1% low 32.6, p99 27.6 ms, CPU 79%, 2638 MHz.

* fix: sessions clean up what earlier ones left in /tmp

The guest's /tmp is a directory in the rootfs that no boot ever empties,
and Android ends sessions by killing them. Every session left a
/tmp/mangohud.XXXXXXXX (mktemp, never removed), and the Steam client, its
web helper, Chromium apps, dbus-run-session, AppImage runs and KDE their
own temporary files and sockets: 1,422 entries on the RedMagic.

mangoapp's config is now one fixed file rewritten each session, and the
session's first pass sweeps each kind of leftover while nothing that could
own one is running, with a single find. On the device that cleared 1,391
entries over two sessions, leaving 38.

The412Banner 715032062d feat: DroidDeck-Proton as a Proton source, and update checks for every source 
Setup > Proton versions lists DroidDeck-Proton (The412Banner/DroidDeck-Proton) beside
GE-Proton and proton-cachyos: same aarch64 tarball pattern as GE, verified against its
sha512 file, installed by droiddeck-proton-extra (also as "droiddeck" in the session queue)
and adopted by steam-compatibility like any other extra, so it shows as
"DroidDeck-Proton <ver> (Compatible)". Its folder has a space; nothing in the install,
adopt, esync or components paths splits on it.

Update checks: each source's newest full release is looked up at app start and when the
page opens, at most every 6 h (offline keeps the last answer). A newer release shows
"Update available -> <tag>" with Update; it installs beside the old build, which stays
until removed ("Remove old ... versions"), since games are mapped to it by name.
Installed builds are ordered by their version numbers (11-9 before 11-10), not by name,
and the tag each was installed from is recorded. Prereleases and drafts are skipped.

The412Banner d1b0ac4df1 Windows components: picked automatically by each game's source (#554) 
Each game's Windows components now come from the list its own source
trusts, and the ones that list names turn on by themselves. The user's own
on/off switches always win; each automatic row says why it is on.

- Steam games: the Steamworks Shared redistributables Steam installs with
  the game (appmanifest SharedDepots, else the client's appinfo.vdf).
  Steam keeps its install scripts marked as already run.
- GOG: the build manifest's dependencies. Epic: the manifest's
  prerequisite (Unreal's maps to VC++ and DirectX). Amazon: fuel.json
  PostInstall. Older GOG/Epic installs get their list fetched once with the
  saved sign-in; game files are never downloaded again.
- Custom games (the + button, Add all, migrated folders): one shared Steam
  match per game, also used for artwork. An appid from the game's files
  turns components on; a name-only match stays Recommended; no match falls
  back to the folder scan.
- Steam app info for apps the client never saw comes from an anonymous
  Steam PICS lookup (CM websocket, anonymous logon, product info), cached
  per appid; the user's Steam sign-in is never used.
- Missing components download in the background on one low-priority
  worker that pauses during sessions and waits on battery saver, heat or a
  metered network unless the user asked. A game Steam installs during a
  session is readied right away so it can be played without ending the
  session; the launch waits up to 10 s only for a component still on its
  way.
- Page: "On for this game" with reasons, a quiet "Checking what this game
  needs..." only for games never worked out, rows that ease in, pieces that
  need a download greyed out while offline. The intro names no other app.
- The folder scan skips Unity's *_Data/Managed (Mono, not .NET Framework).

MaxsTechReview 0e225d0c6e FEX: preload the fault report only where x86 loaders look (#551) 
Preload the FEX fault report only where x86 loaders look

droiddeck-fex put the x86 libfaultreport.so in LD_PRELOAD, which FEX's own
arm64 loader reads too - and FEXServer's, and every child FEX's - so each
x86 start printed "ERROR: ld.so: object '.../libfaultreport.so' from
LD_PRELOAD cannot be preloaded", and an i386 child added "wrong ELF class".
It is now listed in the x86 runtime's own /etc/ld.so.preload, which only
the loaders inside FEX read, as /usr/$LIB/droiddeck/libfaultreport.so.

faultreport.c builds for i386 too, so 32-bit programs get the report as
well instead of an error.

MaxsTechReview d9cd0d2cc8 Desktop: run programs, scripts and AppImages; Switch to Desktop without Deck mode (#549) 
* Run programs, scripts and AppImages from the desktop

Windows programs open with the Proton Steam has chosen, and a Steam game's own
launch program is handed to Steam. x86-64 Linux programs and game scripts run
under FEX, and an exec the kernel refuses goes to droiddeck-open through
libblsession's binfmt.c. Programs on noexec shared storage pass KIO's checks; a
folder of Linux programs there, and sharun AppImages, are added by the app once
and run from the copy. Executable scripts run without KIO's prompt, mpv plays
on the software desktop, FEXServer's socket moves under XDG_RUNTIME_DIR, and
Proton runtimes no longer show up as games.

* Switch to Desktop from Big Picture without Deck mode

Big Picture's Switch to Desktop asks the client's SteamOS manager, which the
client only has when started as SteamOS (Deck mode). Without it the request
failed and the screen stayed on "Switching to Desktop..." for good. The live
compat helper now sees the request on its way to the client and hands it to
steamos-session-select, which opens the KDE desktop as Deck mode already did.

* Run x86 programs from shared storage where they lie

FEX asks for the guest's PROT_EXEC when it maps a program or library, which
the kernel refuses on noexec shared storage; FEX never runs those pages
itself, so libblsession maps them without it in FEX's processes. An x86
game, its libraries and its start script now run in place instead of being
copied in; only native code on noexec storage is still copied.

A Steam library's games are never copied, and a Linux game's launch program
opened from the desktop goes to Steam like a Windows one.

MaxsTechReview eadebc46d5 Performance: idle front end, proot stops, launch-time passes and log collection (#529) 
* Front end: draw the capsule wall without clipping it every frame

The tilted wall clipped each capsule to a rounded rect and recomposed its columns on every drift
step, and a rotated rounded clip is rasterised in software on the render threads: the idle main
page held about 1.7 cores. The art is now loaded at the capsule's size with its corners already
rounded, each column draws its capsules itself in one layer moved by the drift, and the drift
advances at most every 15 ms. The idle page takes about a third of a core.

* libfakeinput: let calls on descriptors it does not serve skip its lock

Every read, write, ioctl, close and poll of every process in a Proton session went through the
controller lock and the three map lookups, Wine's wineserver pipes and the game's files alike.
A bitmap of the descriptors the maps hold, set before one is handed out and cleared when it is
closed, lets everything else go straight to the kernel.

* Pad motion: ask the display for its rotation four times a second

The rotation was looked up for every sensor reading, every 2 ms, and cost more than the rest of
the reading; it is now refreshed every 250 ms, and the readings no longer allocate pairs.

* Session: keep the library passes out of a game's launch

The redist seeder stamped each prefix with the checksum of the whole set of names, which differs
between the session's pass and the game launch's (the game's own names are added), so every
launch re-appended the markers to every prefix in the library while the game loaded. Each
prefix's marker now lists the names it was given and only the missing ones are added.

The beat's seed and compatibility passes, and the Lossless Scaling ownership probe (which loads
steamclient.so), also wait while a wineserver runs: a launch rewrites the manifest and made them
due at exactly that moment. The game's own launch seeds its prefix regardless.

* Agent: keep the focus watcher's X connection open while nothing changes

The connect timeout stayed on the socket, so with no property change the read timed out, and the
watcher dropped the connection, reconnected and took a fresh snapshot every few seconds.

* Game environment: start Cyberpunk 2077 without REDlauncher

The prelauncher opens REDlauncher, a Qt WebEngine window that hands over to the game half a
minute later and then stays up beside it, well over a core busy for as long as the game runs; its
own --launcher-skip started the game twice. The game's executable is started directly instead.

* netif: answer Wine's network driver from a reading of the link

Mortal Kombat X has Wine's network driver enumerate every interface, address and route table
hundreds of times a second. Each enumeration read /etc/droiddeck-net several times, asked the
kernel for its interface dump again (a netlink socket bound under proot, refused each time) and
looked the real functions up with dlsym. The link file is now read at most once a second, a
refused dump is not asked for again within that second, and the real functions are looked up
once.

* Fast path: create memfds without a stop in proot

proot looks at a memfd's name only to refuse the few that are then executed or locked; every other
memfd_create is now issued from the trampoline. The session's /proc/net and status copies made
one per read, a stop each. Without memfd in the kernel the call still goes to proot's ashmem.

* Logs: run each redaction rule only on a line that could match it

A session's end copies some 70 MB of the Steam client's logs and puts every line through all
twenty-odd rules, most of a minute of a core on the phone after every session. Each rule now runs
only on a line holding what it cannot match without: its keyword, the five separators of a MAC,
the four dashes of a GUID, a long enough hex or token run, the learned account or address text.
Lines with non-ASCII text still meet every case-insensitive rule. Over 895,000 lines of real
client logs, with the device's accounts and addresses learned, the output is identical and the
pass takes a twentieth of the time.

* CI: host the Debian image the preloads build in on a release of this repo

The preloads step pulled debian:bullseye from a public mirror on every build whose preload
cache missed; the mirrors rate-limit the shared runner addresses and failed two builds in an
hour tonight. Debian 11 is frozen upstream, so the image is published once (workflow
ci-debian-image.yml, release ci-debian-bullseye-r1, pinned in tools/linuxfs/debian-image.env)
and the build downloads that file; only if that fails does it pull, with retries.

* CI: pin the published Debian image (ci-debian-bullseye-r1, 34 MB)

* CI: a new Debian image rebuilds the preloads (env file joins the cache key)

The412Banner 9b90386e73 Windows components: install from a recording of the installer's result (#495) 
* Windows components: install from a recording of the installer's result

A catalog entry may name a 'snapshot': what its own setup program leaves in a prefix,
recorded once in Wine by winlator-contents' tools/snapshot/record.py (the files it places and
the registry values it writes, the self-registering DLLs' CLSID entries included). With one,
the setup program never runs here: the files come from the archive beside the recording, or
out of the vendor's installer by the paths the recording maps (small generated ones inline),
and the registry values go to registry.json for droiddeck-wincomponents to write at launch.
The steps a recording makes redundant are skipped; DLL overrides still apply. A component
with a recording counts as installable; its prerequisites must still be.

* droiddeck-msi-install --unpack: open archives nested inside an installer

QuickTime's cabinets and an NSIS pack's payloads sit inside the unpacked installer; they are
opened in place into '<name>.nested' folders, two levels deep, the same layout the component
recordings map their file sources to, so a recording's paths resolve on the device (QuickTime:
593 of 593).

Kurt Himebauchandmaxjivi05 ddc4c18faf Steam's touch controller as on-screen controls (beta) (#431) 
* feat: Steam's touch controller as on-screen controls (beta)

* fix: Steam touch controls appear once the session makes the device; tidier default layout

* fix: Steam touch layout decoding, saved layouts and new sessions

* docs: Steam's touch controls

* feat: Steam's touch icons, labels and colours on the touch controls; pick and save them like Steam

* feat: Steam touch icon picker as in-session panels; layout colour; docs

* Give each physical controller its own player slot

Every controller fed the one exported pad, so two pads played as one.
The first controller keeps slot 0 (the Deck in a Steam session); further
ones get slots 1-3 as separate Xbox 360 pads, created on first input and
removed on disconnect. In Deck mode only the Steam client sees those
pads and hands them to games through Steam Input. Rumble follows the
slot it names.

* feat: Steam Link's touch menu, per-game input modes, action set editing, add/copy/paste, oval controls, paste control

* feat: Steam touch controls drawn as Steam Link draws them; Steam Link's touch menu and layout tray

* feat: Steam touch controls in DroidDeck's style, D-mark guide button, shake to hide

* refactor: Steam touch controls become an On-screen controls choice instead of a second dropdown
