Transformers Beyond Reality (UE5, FMallocBinned3) reserves 76 GiB with one
mmap(NULL, size, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS) while libUnreal.so's
static constructors run. Quest grants it; the Frame's kernel (overcommit mode 0) refuses a
writable private mapping larger than RAM + swap, and Unreal's out-of-memory handler then
dereferences its not yet created log: SIGSEGV fault addr 0x10 inside System.loadLibrary.
The patch adds MAP_NORESERVE to every anonymous read/write mmap call site of the engine
library (mov w3, #0x22 -> #0x4022 before a bl to mmap's PLT stub, with x0 = 0 and w2 = 3
in the window), suggested from analysis unreal_binned3 (ANALYSIS_VERSION 22 on main). Triage
unreal-reserve-refused, PLAYBOOK row, tests. Headless on the dev Frame the game now gets
past loading to its OpenXR session and first frames.
ELF helpers find .dynsym/.dynstr/.dynamic by section type and link instead of by name: this
game's libOVRPlugin.so has a scrambled section name table, so add_needed raised
"produced NEEDED=[...]" and the build failed in frame.unreal_ovrp_entrypoints, and
dyn_symbols returned nothing (every ovrp_* lookup then counted as missing).
# Conflicts:

The Frame's runtime has no XR_FB_display_refresh_rate (-7); OVRPort's dispatcher still
offers it and answered 0 Hz. Team Beef's idTech 4 ports run USERCMD_MSEC = 1000 / refresh,
so PreyVR had 0 ms tics: the async thread spun (~1.9M tics/s), com_frameTime stayed 0 and
the main menu's timeline never got past its first step (black backdrop + cursor only).
FrameBridge now always answers with 1 / predictedDisplayPeriod (else the refresh_rate
setting, else 72 Hz). Headless: menu drawn (snapshot mean 68 vs 0.1 before), clocks advance.
- glmv: gl_mv_debug=2 traces draws (state, GL errors per framebuffer), failed texture
uploads/copies/compiles and idTech 4 clocks; how this was found
- triage: a single xrEndFrame -16 is info, not the black-menu error it was blamed for
- PLAYBOOK row, CLAUDE.md fact, host test for the fallback rate
Frames without a projection layer (e.g. PreyVR's menu, a cylinder layer only) gave no snapshot. The snapshot now
takes the first quad/cylinder layer's image instead and logs the layer type, image area, array index and the mean/max
brightness of the submitted area, so a black image shows in the log without fetching the file (#306).
Scared By Squares (Unreal 4.27, OpenXR) creates two actions named "turn"
(an action mapping and an axis mapping called Turn). The Frame's runtime
accepts the duplicate, then vrserver fails to load the input manifest it
builds ("SetXrInputConfig failed. Failed to load manifest"), drops the
app's connection and treats it as exited: black, then the home environment
while the game keeps running with sound. Headless the app reconnected as a
plain OpenXR instance, got throttled to 10 fps and the compositor received
no presents.
- action_dedup (adapter setting, default on): a later duplicate action name
or localized name in a set is created as "<name>_N" / "<Localized> N"
(native/adapter/action_names.h, host-tested). Headless on the dev Frame:
manifest loads, 72 fps, 2808 presents in 45 s (before: 10 fps, none).
- input_diag logs every action set and action (escaped names).
- force_render (hidden diagnostic): xrWaitFrame reports shouldRender=TRUE so
headless runs exercise engines that skip layers when not visible; FrameBridge
logs shouldRender changes.
- Triage: space-warp-used only on the motion-vector swapchain (format 97);
D24S8 (129) eye depth falsely matched. New info finding duplicate-action-renamed.
- Catalog entry (status unknown, min_app 1.2.1), PLAYBOOK row.
Meta's Unity OpenXR features add Detached Touch/Touch Plus/Pro devices on
/user/detached_controller_meta/left|right. Unity merges same-named actions of all devices, so the
first such action (thumbstick) failed with XR_ERROR_PATH_UNSUPPORTED on the Frame (no
XR_META_detached_controllers), Unity attached no action set and neither Unity nor OVRPlugin got
controller input: hands on the floor (Spatial Zombies). Without the extension in the runtime, these
paths are now left out of xrCreateAction subaction paths and suggested bindings, and
xrGetCurrentInteractionProfile answers no profile for them. Headless: actions created, Touch
bindings accepted, action spaces created, no ACTIONSET_NOT_ATTACHED.
Games that suggest controller bindings only for Meta's Touch Plus/Pro profiles got them moved to
oculus/touch_controller, but xrGetCurrentInteractionProfile then answered oculus/touch_controller,
a profile they never suggested. Unity's OpenXR input creates its devices by the reported profile,
found none and left the controllers unconnected: hands lying on the floor, no buttons (Hotel
Infinity). Such hands are now reported with the game's own (last remapped) profile; games that
suggest Touch themselves are unchanged. Logic moved to profile_report.c with a host test.
Unity's Oculus XR plugin asks for SUBSAMPLED eye images through
XR_META_vulkan_swapchain_create_info. With device.foveation on, Valve's
injected FDM leaves their coarse areas in the subsampled layout and the
compositor shows them as garbage around the sharp area (Medieval
Dynasty: black with scattered coloured blocks). foveation_fix=1 only
dropped the XrSwapchainCreateInfoFoveationFB nodes.
The adapter's storage fix (clear SUBSAMPLED from the META node) now runs
whenever foveation_storage_fix is set, also with foveation_fix, and
device.foveation tracked/fixed sets it. Generic form of Batman's
OVRPlugin allocation fix. Adapter rebuilt; revision not bumped.
Star Wars: Beyond Victory's mixed reality showed the room on the game's
objects and black where the room should be. Unreal keeps 1 - coverage in
the scene alpha, and OVRPlugin chains XrCompositionLayerAlphaBlendFB
(colour ONE_MINUS_SRC_ALPHA / SRC_ALPHA) to the eye layer; the Frame's
runtime ignores the struct and blends with the plain texture alpha.
New adapter setting alpha_blend_emul (default on, Vulkan): while
passthrough is emulated and the projection layer asks for inverse
blending, the alpha of the eye image rectangles is inverted in place
(alpha-only blend pass, once per acquired image, queued ahead of the
runtime's submission). layer_debug now also logs the blend factors.
Headless on the Frame: factors (3,2/3,2) seen, inversion runs, 72 fps,
no rejected frames. Not yet checked in the headset.
- il2cpp._run: a non-zero exit or no .cs file under DiffableCs is an unreadable game. The release Cpp2IL dies on
BattleTalent (Unity 2021.3.45f2, exit 134, IndexOutOfRangeException in CsFileUtils.GetTypeName) after making the
folder tree; every class was recorded "missing" and cached.
- find_methods: any release failure gets one try with the development build (it reads BattleTalent), not only an
unsupported metadata version; never with a caller's Cpp2IL or FRAMEPORT_CPP2IL. Errors are cached as errors,
never as missing classes; cache entries with no class found and every wanted class missing are run again.
- Il2cppReturnPatch: Cpp2IL failures become the same WARN check as "code not found" but with Cpp2IL's error line;
the method list in the WARN has no duplicates.
- triage: logcat times include the date (logcat replays kernel lines dated days earlier ahead of the game's; by time
of day the "past midnight" guess gave a healthy run frames-stopped 83261 s). Year wrap handled.
- Il2cppReturnPatch (unity_runtime_msaa_off, unity_multipass, unity_text_input, ...): a patch that is turned on
but whose methods Cpp2IL doesn't find in the game now logs it and adds a WARN build check naming the patch
("not applied (<id>): code not found in this game ...") instead of skipping silently. ApkContext.checks =
checks a patch reports while applying; apply_frame_fixes adds them to the build's checks (job/CLI output,
build record). WARN only: the build still succeeds.
- FrameBridge rect_clamp: an empty projection/quad image rect (BattleTalent's first frames: 0,0 0x0 ->
xrEndFrame -25 twice, then OVRPlugin stops submitting) becomes the whole swapchain image when its size is
known; counted as swapped, logged ("rect_clamp: view N empty image rect -> full swapchain WxH"). Adapter
revision unchanged; artifacts rebuilt.
- triage swapchain-rect-invalid, PLAYBOOK row, setting texts, PATCHES.md, i18n template.
Apply saved refresh rates through SteamVR before Lepton starts, preserve launcher upgrade ordering, and cover the behavior with regression tests. Update the setting documentation and fix repository lint errors blocking CI.
The four fix branches each set ANALYSIS_VERSION 20, which main already used for google_vr (#335); one bump re-analyses older library entries for all their new fields.
Pinball FX2 VR (32-bit, through the a32 bridge) died ~2 s after its loading
screen with "a32: block at 0xf68587a0 overflowed the code buffer" (exit 127):
OpenSSL's sha1_block_data_order_armv8 (reached from RAND_poll) has ~60 SHA-1
crypto instructions in a row, each translated through the interpreter with
its own exit stub, and the block loop only stopped at 96 instructions or half
the code buffer, so the 64-entry stub table overflowed and fatal() ended the
process. The loop now also ends a block while 8 stubs are left.
Headless on the dev Frame the game now runs on past that point (menu-size
swapchains, recenter, its save files written) instead of exiting.
tests/programs/sha1ce.c (72 crypto instructions in a row + an unrolled SHA-1)
failed with the old a32run and passes with the new one, JIT = interpreter.
Triage signature a32-jit-overflow, PLAYBOOK row; frame.a32_bridge marks only
Pinball FX2 VR "Update on Frame" (package_revisions).
Titan Isles (#310) died on GoogleApiHandler with NoSuchMethodError permitUnsafeIntentLaunch(): not the
missing Play services but play-services-basement's PlatformVersion.isAtLeastS()/isAtLeastSv2(), which R8
folded to `return true` in this minSdk 32 build. frame.gms_platform_version makes such constant checks for
Android 12+ return false again (analysis gms_folded_sdk_checks, triage gms-android12-call). Headless on the
dev Frame: runs, 72 fps, no crash.
PianoVision (#297), after frame.unity_appui_vibrator, crashed on MidiDeviceConnectionWatchThread: kshoji's
USB MIDI driver polls UsbManager, and Lepton has no USB service (null). frame.usb_midi_watcher makes
checkConnectedDevices return at once (analysis usb_midi_watcher, triage usb-midi-watcher). Host-tested.
PianoVision quit about a second after start on the Frame: Unity App UI's activity
(com.unity3d.player.appui.AppUIGameActivity) calls getSystemService("vibrator_manager") and casts to
android.os.VibratorManager in onCreate without a version check; Lepton runs Android 11, so
NoClassDefFoundError before Unity starts. The sequence now leaves its registers null (the field store and
the rest of onCreate stay) and the activity's methods that read the vibrator return at once (in-place dex
edit). Suggested by analysis unity_appui_vibrator (ANALYSIS_VERSION 20) and triage unity-appui-vibrator.
Escaping Wonderland's Meta start-up (OculusPlatform.<Initialize>d__13) awaits
Users.GetOrgScopedID after the licence check and the logged-in user, when on
Wi-Fi, only for its analytics id. OVRPort's ovr_User_GetOrgScopedID returns
request id 0, Meta's C# wrapper logs "An unknown error occurred. Request
failed." and never calls back, so the game waits forever. The patch takes the
game's own no-Wi-Fi path for that request (b.ne after cmp w0,#2 on
get_internetReachability -> b, found with Cpp2IL). Analysis flag
cortopia_org_id (ANALYSIS_VERSION 20), triage cortopia-org-id-wait, PLAYBOOK
row, tests. Headless on the dev Frame: past the loading screen into the intro
scene (adventurer spawned), 72 fps.
Photon Voice's AudioInAEC.updateAudioDevice calls getAvailableCommunicationDevices/setCommunicationDevice with no version check; on Lepton's Android 11 the microphone thread dies with NoSuchMethodError (Table Troopers at the tutorial). New patch frame.photon_voice_audio_route (analysis photon_voice_api31, ANALYSIS_VERSION 20) makes it return at once, sharing vivox_audio_route's helper; Vivox's patch is unchanged. Triage vivox-api31 / photon-voice-api31 now look for the SDK in the stack; other libraries fall to audio-api31 (report).
Unity games log 'An unknown error occurred. Request failed.' from
Oculus.Platform.Request.OnComplete when a Meta call gets no usable answer
(Thief Simulator #368, Eleven #346, Spectre #360): warning + report. Games with
their own copy of Meta's platform loader abort with 'DisplayErrorAndExit:
Failed to launch SystemActivities' (Breachers #357): fatal, replaces the
generic native crash. PLAYBOOK rows, tests from the reporters' logs.
The reporter's read-before-write fix for module 16800_8dbab031 (12 int Function
variables loaded before any store, the same bug as Vader Immortal's lightspeed
shaders), headset-verified: past the loading screen, ~28 min at 72 fps.
Sections now run from what most users need to what only some need:
Updates, Installing, Library folders, Appearance, Data, Problems and
feedback, Install links, Tools, This PC, About, Uninstall. Updates gains a
Games part: game recipes from GitHub (moved from Data) and the new
"Check games from install links for new versions" switch with its last
check and Check now. Inside sections the common options come first
(Installing: parallel uploads and video before keep-copies; Updates: dev
build last; Appearance: language first when a translation exists).
The demo manifest (site + built-in copy) names version 1.0.0 as an example;
the demo link is still never fetched or checked (test).
A manifest may name its build's version (top-level "version" or
"frameport": {"version"}). FramePort keeps it with the game's link record
and, at start (at most every 6 h), fetches remembered web manifests again;
a newer version marks the game link_update. The Library bar and the game
page offer to download and install it (one confirmation, same download path
as a first install, a name the user gave is kept). CLI: frameport
link-updates [--install]. Docs: INSTALL_BUTTON.md.
From working-recipe issues #378, #377, #376, #375, #364, #363 (validated with
scripts/catalog_from_issue.py). The 7th Guest VR: the foveation darkening
diagnostic (foveation_test) left out, title spaced, notes shortened to the
game-specific findings. FGO VR: scale rounded to 1.2.

categories, enableVrMode=com.google.vr.vrcore, libgvr.so / Cardboard SDK libs,
GVR Java classes, Unity vr-device-list (not libgvraudio.so, which Quest games
ship too). A build without Oculus support gets a warning (recipe notes, CLI,
game page); never unsupported from the manifest. Triage gvr-not-supported for
Unity's 'Google VR Error', the bridge's missing CardboardViewNativeImpl and
VrCore binds. PLAYBOOK row, tests.
CLAUDE.md was ~150k characters (over Claude Code's instruction-file limit together with CLAUDE.local.md). The dated investigation narratives move verbatim into docs/DEVICE_NOTES.md; CLAUDE.md keeps a one-line pointer per block with the key fact and the patch/setting names.
Doom3Quest's shader sources start with a newline before #version (raw string literals). GL drivers accept that, but
glslangValidator's ES profile rejects it, so the optional validator step failed wherever glslang is installed.
The copy it checks now starts at #version; the rewriter output itself is unchanged.
Agent v94: _backup_saves / _restore_saves stream a tar.gz of a game's internal
and external Android storage over the SSH exec channel (caches, IL2CPP and
shader caches, FrameBridge files, videos/OBBs and files over 64 MiB left out;
manifest with sha256 last). File work runs in podman unshare, holds the
launch lock and is refused while the game runs. Restore treats the archive as
untrusted (confined paths, no links/devices, size limits, hashes checked,
staged first), keeps the replaced saves as saves-before-restore.tar.gz (undo)
and puts them back if swapping fails.
PC: install/saves.py (save-backups/<pkg>/, keep 10 by default), game menu
section Saves (back up, restore..., open backups folder), Frame page
"Back up all saves", back up before deleting saves on uninstall, Settings ->
Data keep count, CLI frameport saves backup|list|restore|undo.
Settings -> Library folders lists the folders Rescan scans (scan.roots: status,
games from each, remove, Add folder...), CLI frameport folders / rescan.
A scan that finds a library game elsewhere whose own files are gone and that
is the same build points the entry at the new place (title, tags, art, user
recipe, builds and installs stay); another version is taken only by Scan a
folder... (as Update with a newer APK/version), Rescan reports it; a second
copy leaves the existing one. A full scan no longer overwrites a user recipe.
bootstrap.sh and Frame.install_key appended with echo >> after an exact-line grep; a file whose last key had no
newline got FramePort's key glued onto it, which sshd never matches, so OpenSSH uploads were refused while Paramiko
logged in with the user's own key. Both now add the missing newline first (one shared install_key_command).
Source of truth: announcements/current.md on main (front matter: id, title,
date, optional image/button/expires; Markdown body), read from raw GitHub every
6 h like the catalog, so a push reaches users without a release. Ships
switched off (active: false).
Shown only to people who used FramePort before the announcement's date, never
on a first start; any close (X, click outside, Escape) dismisses that id for
good, and a new announcement = a new id. Centred over the content area, right
of the sidebar. announcements/README.md explains the file;
ui_smoke.py --announcement renders it.
Follow-up to "Update with a newer APK…": Linux apps take their new AppImage/archive or folder (a file or a folder
picker, like the app was added), PC VR games their new game folder. pipeline.replace_linux_app / replace_rift_game
re-run the add path (add_linux_app(replace=) / add_rift_game(replace=)): the entry keeps its package (so the Steam
shortcut), name, artwork, tags, switches and the user's recipe; a folder keeps the program chosen before if it's still
there, else FramePort picks again (and asks, for ambiguous PC VR games). A name that looks like another app's is
allowed with a heads-up.
The entry gets a new source_id, recorded in the deployment's recipe at install (no agent change):
components.source_replaced shows the Frame copy (and a PC install, pc_outdated) as outdated until then. Such an
install also re-sends same-size files changed after the last install (installer.changed_since), since uploads
otherwise skip files the Frame has with the same size. The old PC VR folder is left out of later scans
(replaced_dirs). CLI: frameport new-version <game> <path> (APKs too). Docs: INSTALL.md.
A Frame that only authorizes the user's own key refused OpenSSH, which
offered FramePort's keys alone (IdentitiesOnly), so every upload fell back
to Paramiko. The connection now records which login worked (Frame.auth):
after a login with this PC's own keys/agent OpenSSH also offers private
copies of ~/.ssh/id_* (OpenSSH skips its defaults once -i is given) and the
agent; a refused strict login is retried that way once. FramePort doesn't
add its key to the Frame for this.
New: Settings > Installing > SSH keys (library ssh.extra_keys, CLI
frameport frame ssh-keys): extra private key files for the connection and
OpenSSH, checked with Paramiko (passphrase keys: use the agent). OpenSSH
runs with -v and a refused login's error lists the keys offered and its
warnings. whoami's SID is read from bytes (non-ASCII user names).
Checked with Windows ssh.exe/sftp.exe against the Frame.
sftp escapes * ? [ inside double quotes itself, so FramePort's extra
backslash became part of the path: a folder named "... [ENG] ..." failed
every OpenSSH upload (on Linux too) and fell back to Paramiko. On Windows
the local path now goes with forward slashes: Win32-OpenSSH turned every
backslash, escapes included, into '/' ("C://Users", "/[ENG]").
Checked with Windows sftp.exe and Linux sftp against the Frame (put and
reput, sha256 match).
Deadly Delivery 1.0.30 renders (72 fps), then its lobby's Meta entitlement check
fails four times and it quits. The oculus-entitlement signature is PC VR only,
so the Quest log had no finding. New Quest signature meta-entitlement (error:
offline games may log it and play on; an online game's exit fails the test).
FramePort doesn't get around entitlement checks. docs/GAMES.md regenerated
(it was also behind on other catalog entries).
Consolidates the reusable mechanics: issue templates/labels, the
working-recipe -> catalog path (scripts/catalog_from_issue.py), handling
diagnostics zips (and the attachment-vs-placeholder gotcha), how a change
reaches users (catalog ~6 h vs code needing a release/dev build, and not
bumping a shared revision for a narrow fix), and verifying a device fix
headless. Identity/credentials stay in CLAUDE.local.md.
Doom3Quest-based ports (PreyVR, #306) draw their menu on a curved
cylinder layer submitted once per eye. The Frame's runtime has no
cylinder layers, so FrameBridge shows each as ~7 flat quad strips; a
per-eye pair is ~14 quad layers in one frame, which the runtime rejects
whole (xrEndFrame -> XR_ERROR_LAYER_INVALID, -16). The menu then stays
black while the game runs at 72 fps.
Collapse the pair: drop the right-eye cylinder and show the left eye's
strips to both eyes (the runtime composites a quad to both eyes anyway).
That halves the layer count and drops the per-eye eyeVisibility, and the
runtime accepts the frame. Only frames with per-eye cylinders change --
exactly the ones that were being rejected; mono (BOTH) cylinder games
such as 4XVR are untouched.
Verified on the dev Frame (headless): PreyVR v1.2.4 rebuilt + installed,
the menu frame now submits (one transient -16 on the first frame before
the space is locatable, then clean), 72 fps. Visual confirmation of the
menu needs the headset. Triage signature cylinder-menu-layers-rejected.
No adapter revision bump (installed games are not marked outdated).
Diagnostics only (no behaviour change): the "new layer ... usable=0"
line prints a layer's swapchain pointer, but creation logged only the
result, so a dropped layer couldn't be matched to the xrCreateSwapchain
that made (or failed to make) its swapchain. Needed to pin why a quad
"screen layer" is dropped (#306 PreyVR: menu rendered to a quad whose
swapchain FrameBridge reports as not usable).
Headset-confirmed working configs shared through the issue form:

Version 1.2.0; catalog min_app 1.1.2 -> 1.2.0 for the entries that need this release (Shadow Point, Medal of Honor, Assassin's Creed Nexus, Journey of the Gods).
Turns on frame.unreal_skip_obb_delivery (and keeps frame.hw_video_decode) so
the fix applies without the user finding the toggle. Not device-verified (the
game is ~41 GB); status unknown, min_app 1.1.2 so only builds that recognise
the obfuscated DownloaderActivity get it.
Medal of Honor (com.Virtuos.R6DLM) keeps Epic's DownloaderActivity and log text but renames the delivery predicates
and OBBData, so expansionFilesDelivered wasn't found and frame.unreal_skip_obb_delivery was never offered. Detection
now also matches a boolean method in the package's DownloaderActivity, called from onCreate, that carries Epic's
"Checking for file : " log and calls the expansion-downloader helpers; the patch rewrites those too. ANALYSIS_VERSION
18 -> 19. Heuristics eval unchanged (10/66); no existing recipe affected.
The GLES-only stand-in left Vulkan games (UNDERDOGS: VkFormat 43, faces=6) with the runtime's refusal, so OVRPlugin
crashed in ovrp_EndFrame4. When there's no GLES context, the adapter now makes a cube-compatible VkImage (6 layers,
the requested format/size/mips, usage from the XR flags) with the app's device/queue and a private transient pool,
transitions it to COLOR_ATTACHMENT_OPTIMAL, and enumerates it as a Vulkan image; its cube layers are still dropped.
GLES behaviour is unchanged. Adapter rebuilt deterministically (both ABIs).
Pre-#263 agents left shortcuts.vdf entries with both appname and AppName; vdf_decode then refused the file
("duplicate VDF key") and Add to Steam library failed. Duplicates are now merged into one key: Steam's capitalized
spelling kept, the last value taken. Clean files still round-trip unchanged.
Only big files (>=8 MiB) used OpenSSH; games made mostly of small files stayed on Paramiko and were slow on a fast
link. native_upload.put_tar streams the same tar batch through system ssh with the paired key and pinned host key;
on any failure the install falls back to Paramiko's put_tar and logs it, and doesn't retry OpenSSH for later batches.
The job log now names the transport for each part. upload_bench gains app-small / paramiko-small comparisons.
- unreal-obb-check-stuck names frame.unreal_skip_obb_check (CRC, needs bVerifyOBBOnStartUp) and
frame.unreal_skip_obb_delivery (the Java name/size gate), and says neither is a guaranteed fix.
- cube-swapchain-refused: the stand-in is GLES-only; a Vulkan game can't use it yet.
- A game that submitted projection frames but then logged no pacing summary for 20 s (process alive) is reported as
frames-stopped (info), so a hang like SKYBOX's signature check isn't a false pass. Headless no-tracking ends are
excluded.
Play on the Steam Frame tab for a game no longer in the library wrote last_played with upsert_game, which created an
entry with only that field: listed under its package name, "Update ready", and Update / Game settings failed with
KeyError 'recipe'. library.set_fields updates existing entries only (last played, test and session results, tags,
toggles); a one-time migration drops entries made of side notes alone.
After "Waiting for app", a failure line or 20 s without a logcat line start FramePort's own reader, from the
launcher's start (logcat -T <epoch>) when the mirror never wrote, else from just before its last line. The reader
restarts from where it ended, stops when Lepton's lines come back, the container's log buffer is 16 MiB, and every
decision goes to logcat-keeper.log.
Merged main (agent 90, ANALYSIS_VERSION 17/18 after main's 15/16) and rebuilt the bridge, foveation and a32
libraries from source (deterministic, no local paths).
Fixes on top:
- a32 loader: apply DT_ANDROID_RELR relocations (Journey of the Gods crashed at start)
- VrApi bridge: vrapi_Get/SetTrackingTransform (floor-level tracking; Shadow Point's player was below the floor)
- a32: never submit an untracked default head pose (hold up to 100 ms, repair or drop); pose consistency per display
time; submit/tracking counters
- VrApi bridge: wait again when xrWaitFrame gives a display time in the refresh just submitted (the runtime rejected
the second frame with AlreadySubmitted; Journey of the Gods ran at ~120 fps on a 90 Hz display and the scene slid
and snapped back); pacing counters
- VrApi bridge: GLES re-entry polls events before reusing the kept session (a lost or exiting session is replaced, a
stopped one waits for READY)
- VrApi bridge: STAGE is the runtime's STAGE space (play-area centre and orientation, unchanged by recentering);
LOCAL_FLOOR keeps the head-based origin
- signer certificate: pick the certificate the SignerInfo names, not the first in the PKCS#7 block
- flat 32-bit apps keep the bridge (it isn't a VR-only fix)
- Frida gadget loads are stripped before translation
- launcher restart test fixed; native/.cache is no longer committed
- catalog: Shadow Point and Journey of the Gods work (headset, 2026-10-14; min_app 1.1.2)
Rebuilt libvrapi.so and libvrapi_foveation.so without the local NDK paths a worktree build left in their debug info; a test checks that no artifact contains a local path.
On Frames whose Steam drops FramePort's shortcuts.vdf entries on every restart
(GitHub #41/#42), "Add to Steam library" restarted Steam twice and then failed
with "Steam removed the new library entry again after restarting". Play's
fallback (the devkit entry, the one Steam keeps) was never reached because
_add_then_play gave up first.
After the second loss the shortcuts worker now adds the devkit entry while
Steam runs, so the game ends up in the library as "Devkit Game: <title>" and
the job succeeds. Agent v89.
- Check the Steam shortcut on every update, also when nothing else changed: a connection lost during
"Add to Steam" or Steam putting its old shortcuts.vdf back left games without a library entry. The
agent restarts Steam only when the entry really changes.
- Artwork updates for installs without a recorded artwork manifest start from a clean folder again
(an old portrait.jpg next to a new portrait.png was picked at random for the Steam grid).
- OpenSSH uploads only rename .part files that are already complete (sftp's reput refuses them, which
sent every resume to the Paramiko fallback).
- frame.tbxr_vendor revision 2: GL4ES ports get "Update on Frame" for the #191 draw fix.
- Configuration-only updates send the library's current Steam tags.
- finalize drops fingerprints and the artwork record an older app didn't send.
- set_settings: malformed numbers are refused before anything is written; int settings keep a
fractional value.
- Display diagnostics use Windows PowerShell 5.1 without pwsh's PSModulePath; window diagnostics and
the instance owner file can't stop the GUI from starting.
Holding the Frame's menu button turned 32-bit (and other VrApi bridge)
games 90-120 degrees to the side. The bridge's app space is LOCAL plus
the head's yaw at the start; the runtime's recenter moves LOCAL to the
head, so that old yaw was applied again. On a LOCAL reference space
change (and on vrapi_RecenterPose, ignored before) the origin is taken
from the head again in the first frame after the change, and VrApi's
recenter count goes up. Owner-verified with Gunjack.
The upstream patches are regenerated against OVRPort 5e7df52 (they
were missing the FOV cache changes).

Moving the mouse over the Library right after its cards were rebuilt (e.g.
the library changed at start, or a view switch) could deliver a hover event
for a card that was already off the page. Its handler called tile.update(),
Flet 1.0 raised "Container(…) Control must be added to the page first", and
an error in an event handler takes the whole app down to Flet's error
screen.
- Library grid and shelf card hover handlers use the safe C.update(tile),
which skips controls that aren't on the page any more (the convention
everywhere else in ui/)
- Settings' index: scroll_to on a page that has already left the screen
(or a closed window: "Session closed") is ignored instead of raising in
the task callback
Seen on the desktop app (Linux) while testing the a32 branch; the code is
the same on main. No automated reproduction (needs a real hover during a
redraw).

Recipes the user edited (source "user") are never re-derived, so a 32-bit
game whose recipe was saved before the bridge existed kept OVRPort and the
64-bit fixes and no bridge. Since 95c5de9 such a recipe can't be built at
all (build.check_a32), so it needed fixing by hand.
The one-time migration a32_bridge_on (library._migrate, after
quest_binary_fixes_v2, which adds frame.vk_sanitize to every Quest recipe)
goes over every 32-bit-only game once:
- adds frame.a32_bridge with the patch's own reason, unless the game's
catalog entry removes it (frame_remove)
- then engine.a32_recipe as for a bridge just turned on: OVRPort and the
64-bit fixes off, device.text_input_window for Unity, a pre-bridge
"unsupported" becomes "unknown"; the recipe stays the user's
- recipes that already have the bridge only lose what it replaces
- skips 64-bit games, PC VR / Linux entries and "install unchanged" games
It runs once per library, so a bridge the user switches off afterwards
stays off.
Tests: a user recipe from before the bridge is migrated, a catalog
frame_remove and a 64-bit game are left alone, switching the bridge off
afterwards sticks; the game page switch test now starts from a migrated
library.

Two ways a 32-bit game ended up with a recipe that couldn't work:
- Catalog entries written before the bridge existed (Journey of the Gods,
Shadow Point: "unsupported: the Frame has no AArch32") dropped the
heuristic bridge suggestion like any other patch the entry didn't choose.
- Turning the bridge on by hand kept OVRPort and the 64-bit-only fixes
(e.g. frame.vk_sanitize) on; they then failed in the build.
Now:
- A catalog entry for a 32-bit game that neither names nor removes
frame.a32_bridge counts as older than the bridge: the bridge stays in,
"unsupported" becomes "unknown" and the note says it's untested with the
bridge (quoting the old verdict). Entries that name the bridge keep their
own verdict.
- engine.a32_recipe (was _a32) also runs in pipeline.set_recipe (game page,
CLI `recipe --enable`, Game settings dialog) and before every build. When
the bridge has just been turned on it also adds what it needs (Unity:
device.text_input_window) and lifts a pre-bridge "unsupported"; later
saves only remove, so a patch the user turns off stays off.
- Which patches work on the bridge is declared per patch instead of two
lists in the engine: Patch.a32 / base.works_on_a32. OVRPort and Frame
fixes are off unless they say a32 = True (the bridge, the adapter, the
launcher entry); FrameBridge settings work unless they need the xrshim
(settings.XRSHIM_SETTINGS, the same list frame.adapter's needs_xrshim
reads now, so a new xrshim setting is excluded by itself). Such patches
are hidden for 32-bit games, also in the Game settings dialog.
- build.check_a32 refuses a 32-bit build without the bridge, or with OVRPort
or a 64-bit fix on, with a plain message instead of failing inside a tool
or producing an APK the Frame rejects (INSTALL_FAILED_NO_MATCHING_ABIS).
engine.warnings(recipe, analysis) says the same on the game page.
- The game page redraws the patch list when the bridge switch changed other
patches; its save uses C.update (warn.update raised when not mounted).
- Parity: a bridge build whose known-good APK is from before the bridge gets
"new build (no baseline)" (no alt check either) and is listed apart from
the games at parity, instead of UNEXPLAINED.
Tests: catalog verdict old vs tested, bridge turned on by hand (incl. a
later switch-off staying off), the lifted status, works_on_a32 per category,
check_a32, warnings, parity baseline + report, and the game page's switch
driven headless (no browser). Not yet built for or run on the Frame with
Journey of the Gods / Shadow Point.

Sports Scramble (a 32-bit Santa Cruz build: UE 4.21, OVRPlugin on VrApi 1.21)
now plays in the headset with both controllers.
a32 bridge:
- AAsset_getBuffer: the host buffer lies above 4 GiB, so the guest gets a
copy in its own memory, freed in AAsset_close (Unreal read its
UE4CommandLine.txt this way and aborted on the NULL it got before)
- AKeyEvent_getFlags and the remaining AConfiguration getters
- Touch controllers for Quest builds: apps that require 6DoF head tracking
(uses-feature android.hardware.vr.headtracking version 1) get
assets/fp_a32_headset.txt = "quest" at conversion; the bridge then passes
both Frame controllers through (input devices, caps, state, tracking,
vibration; struct tails per VrApi minor) and sends no synthetic touchpad
events. Gear VR / Go games keep the remote emulation. A32_TOUCH=1/0
overrides.
Analysis: detect.requires_6dof, headset "quest" for such 32-bit apps
(ANALYSIS_VERSION 13).
Agent 82: Unreal restarts the app once after its first-run shader precompile
(the "optimizing" screen): it starts its own launcher activity and exits, and
Lepton ends the container with the first process. Skipping the restart or
turning it off (r.ProgramBinaryCache.RestartAndroidAfterPrecompile=0) left
the game on that screen for good. launch.sh now starts Lepton once more when
the system log shows the app's own LAUNCHER start right before its
System.exit(0) (_restart_requested; first run kept as
launch-before-restart.log; FRAMEPORT_NO_RESTART=1 turns it off).
upgrade_launchers adds it to existing launchers. Crashes, quitting from the
game and Steam's Exit game don't match.
Catalog: Sports Scramble works (owner, headset, 2026-10-13).

Profiled Gunjack and Spunky Dungeon on the Frame with perf and a new
A32_PERFMAP option (a perf map of the translated code: block bodies, exit
stubs, FPCR writes). FPCR switches turned out negligible (8 of 86k samples,
none in Gunjack). The cost was elsewhere:
- The run loop took the translation mutex on every dispatch and walked a hash
chain under it (Gunjack: jit_run 23.6 % of all samples, pthread_mutex_*
about 7 %, plus futex time in the kernel).
- The inline lookup table for indirect branches was only written at
translation, so a hot return target lost its slot for good to any block
translated later into the same slot and went through the run loop ever after.
- Every dispatch did an atomic add/sub on a counter all threads share (4.7 %).
- jit_invalidate scanned every block on each cacheflush that touched a code
page: Unity's Mono JIT does that constantly (72 % of Spunky Dungeon's main
thread in one run).
Now:
- the run loop looks blocks up without the lock (inline table first, then
the hash chains, published with release stores); the lock is only taken to
translate or to chain the exit it came from
- it refills the inline table with every block it dispatches; the refill and
invalidate_block are fenced against each other, so an invalidated block
never stays reachable
- HASH_BITS / LTAB_BITS 16 -> 18 (Gunjack translates well over 100k blocks)
- a per-thread in_jit_section flag + fence instead of the shared counter;
flush_cache sets flush_pending and waits for the flags (threads_any_in_jit)
- per-guest-page block lists: an invalidation visits only the blocks on the
affected pages and drops invalid ones from the lists on the way
Results on the Frame (same build otherwise, same launch conditions):
- Gunjack, 25-45 s after start with OVP_HEADLESS_TEST: 100,462 -> about
45,000 samples in 20 s (about 55 % less CPU), jit_run 23.6 % -> 1.6 %,
pthread_mutex_lock about 7 % -> 0.4 %
- Gunjack, 12-27 s: 72 fps in both, 11,306 -> 9,801 samples, jit_run
10.4 % -> 1.0 %
- Spunky Dungeon, 12-27 s: 72 fps in both; translated code is only 2-3 %
there, so no change. The jit_invalidate phase wasn't reproducible headless
under identical conditions: not yet measured in a played session.
- bench.c (single thread, few dispatches): unchanged.
Tests: run_programs.py (jit + interp, and A32_CACHE_KB=300), bridge harness,
fuzz.py arm-dp / t32 / arm-vfp / arm-neon (0 mismatches), pytest. Both games
pass their launch tests at 72 fps with the final build.

Gunjack (CCP, Unreal Engine 4.10 NativeActivity, VrApi, GLES) runs on the
Frame through frame.a32_bridge, confirmed in the headset by the owner
(2026-10-12). The recipe needs only frame.a32_bridge: the engine adds the
adapter and the LAUNCHER fix and turns OVRPort off, the same patch set as
the build now on the dev Frame.
Notes give the controls (right controller): trigger = fire, A = tap, stick
down = reload (swipe back), stick up = special weapon (swipe forward),
B = back. GAMES.md and the patch docs regenerated.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Gunjack (UE 4.10, Gear VR) has no separate reload or special-weapon input on
the touchpad: every swipe goes to UE4's Gesture_Flick, and
ATDPlayerController::OnFlick reads the flick angle. Below 45 or above 315
degrees (+X, a swipe towards the back of the Gear VR touchpad) it reloads;
135 to 225 degrees (-X, a swipe forward) fires the special weapon. Up and down
swipes do nothing. The bridge sent the stick's up/down as Y swipes, so in
Gunjack those directions did nothing.
For games that read their AInputQueue (NativeActivity), the right stick's
up/down now swipe along the touchpad's own X axis: up = swipe forward
(special weapon), down = swipe back (reload). Left/right are unchanged.
Unity games (AFFECTED, Spunky Dungeon) keep their mapping.
Rebuilt liba32bridge.so. Gunjack was rebuilt and installed on the dev Frame;
the headless launch test passes. Not yet tried in the headset.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Gunjack (UE 4.10, Gear VR) imports no vrapi input functions: it reads the
Gear VR touchpad and back button as Android input events from its
AInputQueue (native_app_glue). The bridge delivered its controller events
through Activity.dispatchKeyEvent, which never reaches native code, so no
control worked at all.
input.c now queues synthetic events in front of the game's AInputQueue:
- AInputQueue_attachLooper (without a callback) registers the queue;
ALooper_pollAll/pollOnce return its ident while a synthetic event waits
(ALooper_wake ends a blocking poll), AInputQueue_getEvent hands it out,
finishEvent frees it.
- The AInputQueue/AInputEvent/AKeyEvent/AMotionEvent imports are written
by hand ("!" in imports.txt) and answer for synthetic events; real
events go to libandroid as before.
- Touch positions are scaled to the activity's window size
(native_activity.c records it).
Mapping (right controller, as for AFFECTED: The Manor): trigger = hold
the touchpad, A = tap, right stick = swipe, B / left menu = back. Unity
and other Java-delivered games are unchanged. A new input_start (VR
re-entry) ends the previous poll thread.
Also: the libandroid functions the host side calls directly are weak
references again, so the PC test harness links (it broke with the
AAsset calls of the signature loader); bridge/test/run.py passes.
Headless on the Frame: "controllers: the game reads its AInputQueue",
72 fps. Not yet verified in the headset.
Gunjack (CCP, UE 4.10, Gear VR) quit after loading because AndroidMain compares
GameActivity.AndroidThunkJava_GetSignature() with the original signing
certificate, and then crashed in the Frame's runtime when it entered VR again.
a32 bridge:
- frame.a32_bridge: original_signature() = Base64.DEFAULT(SHA-1(signing
certificate DER)) of the original APK (META-INF/*.RSA|DSA|EC), stored as
assets/fp_a32_signature.txt for libUE4.so games (convert(), shared with
bridge/convert.py)
- the bridge loads it at activity creation and answers guest calls on the
method ID of AndroidThunkJava_GetSignature()Ljava/lang/String; with it
(replaces the unused hex/OpenSSL prototype)
VrApi bridge: after loading, Unreal leaves VR mode and enters it again on the
same GL context; the first frame of a second OpenXR session there aborted in
vrclient (CSharedSemaphoreLinux::WaitFromGPU from the GL binding's
PreBeginFrame). vrapi_LeaveVrMode now keeps a running GLES session and
vrapi_EnterVrMode reuses it for the same context (another context still gets
a new session; Vulkan unchanged). upstream-patches/runtime.cpp.patch updated,
libvrapi.so and liba32bridge.so rebuilt.
Verified on the Frame: headless launch test passes (72 fps after re-entry);
owner-verified in the headset.

32-bit-only APKs (Gear VR / Oculus Go games) are no longer "unsupported": the
recipe engine suggests frame.a32_bridge, which converts the APK with the
translator bridge (convert() shared with bridge/convert.py) and ships
liba32bridge.so / liba32rt.so / liba32stub.so (native/build.py --only a32).
FramePort:
- engine._a32: overport off (OVRPort is 64-bit only; the patch ships OVRPort's
loader chain + its 32-bit platform dispatcher, overport.ensure_runtime_lib),
only frame.a32_bridge/adapter/launcher of the frame patches, 64-bit-only
adapter settings dropped, device.text_input_window for Unity; such patches
are hidden in the UI
- analysis extra.headset (ANALYSIS_VERSION 9): quest / go / gearvr ->
"Gear VR" / "Oculus Go" platform + Steam tag; catalog `headset:` field
- expects_obb ignores Unreal's OBB-inside-the-APK (assets/main.obb.png)
- catalog: com.fallen.affected, net.mobilemischief.spunkydungeon
Bridge / translator:
- VrApi 1.31 + Unity 2019 (no-config EGL contexts, LOCAL_FLOOR/STAGE tracking
space), GL buffer mappings per buffer object (fixes a ~10 MB/s guest leak and
garbled vertices), Go controller mapped to the right Frame controller
- native_app_glue imports (ALooper/AInputQueue/AConfiguration/AAsset*) for
UE4 NativeActivity games (Gunjack: runs, then quits on its own APK signature
check, which FramePort doesn't defeat)
- debugging aids: A32_BREAK, A32_STRACE to logcat, lifecycle/LeaveVrMode logs
vrapi-bridge: honours LOCAL_FLOOR/STAGE, picks a window/RGBA8 ES3 config for
no-config contexts; upstream patch updated, libvrapi.so rebuilt.
Verified on the Frame: Spunky Dungeon (Unity 2019.2, OVRPlugin 1.46) plays at
72 fps; AFFECTED The Manor still runs.

32-bit ARM (armeabi-v7a) libraries run inside a normal 64-bit Android app on the
Steam Frame, without Android's native-bridge mechanism (no Lepton changes): each
libX.so becomes libX.a32.so plus a 64-bit stub, next to liba32bridge.so (the
translator + host glue) and liba32rt.so (a 32-bit static-PIE runtime with bionic's
libc/libm/libz/libstdc++ and a loader for the game's libraries). Guest and host
talk through hypercalls (SVC 0, r7 = 0x0a32xxxx).
Bridge (native/a32translator/bridge):
- JNI both ways: generated + hand-written JNIEnv/JavaVM, RegisterNatives and
Java_* exports through AAPCS64 -> AAPCS32 trampolines, handles for references,
arrays/strings shared when below 4 GiB, else copied
- NativeActivity glue, libandroid imports (weak, generated from imports.txt)
- GLES 3.2 + extensions + EGL: 996 functions generated from the NDK headers
- OpenSL ES output implemented in the guest, played through AAudio
- VrApi 1.x (Gear VR era) translated to the 64-bit VrApi -> OpenXR bridge,
including OVRPlugin 1.12's frame layout and its wrapped (app texture) chains
- controller input as Gear VR touchpad/back/gamepad events (UnityPlayer.injectEvent)
- convert.py: prototype of the APK conversion (FramePort patch to follow)
- PC harness with a fake JVM (32 checks, qemu or native) and an on-device test APK
Translator fixes found on the way: guest signals during blocking system calls
and in host code (Boehm GC deadlock in Unity's Mono), static-PIE start files and
PT_TLS/PT_GNU_RELRO bias, host fault chaining, stderr to logcat in bridge mode.
vrapi-bridge: OVP_HEADLESS_TEST=1 skips the wait for a tracked head (automated
tests without a worn headset); upstream-patches/runtime.cpp.patch updated.
Verified on the Frame (2026-10-10): AFFECTED The Manor (Unity 5.6 + Mono,
OVRPlugin 1.12) runs in the headset with picture and sound; controls in progress.

Interpreter + JIT for ARM, Thumb-2, VFPv4 and NEON, ARM EABI syscall
translation, signals, threads and self-modifying code. Runs static bionic
programs on the Frame. Tests: A64 encoders vs llvm-mc, a differential

README lists the steps towards running 32-bit-only APKs.

Agent 85: the game's container gets the host's /dev/input at /dev/fp-input (Lepton's /dev/input holds its own Wayland
input pipes) and the launcher's _gamepad_links worker keeps /dev/input/eventN links to Steam Input's virtual pads in
step while the game runs: controllers switched off and on again (Steam makes a new pad) work without a restart.
Android's EventHub adds and removes the links through inotify (dev Frame, uinput stand-in pad created after boot:
New device, Device removed, added again). Older launchers get the new gamepad line through upgrade_launchers.
The key layout also maps BTN_DPAD_* (a Steam Input layout that sends the D-pad as buttons, e.g. a stick set to
D-pad; the Frame's controllers have no D-pad of their own).
Pick the new APK from the game's right-click or … menu: pipeline.replace_apk checks it's the same app (refuses
another package, warns when its versionCode is older), points the entry at it and analyses it again; title, art, tags
and the user's own recipe stay, the game data stays unless the new APK's folder has its own. The game page then
offers Update on Frame.
- HostKeyChanged (paramiko BadHostKeyException): not treated as "can't reach" (jobs don't pause and retry); the
Steam Frame page explains it and offers Trust the new key (forget_host_key + reconnect); CLI frameport frame trust-key.
- Uninstall from the running app: instance.release() drops gui.lock before the data folder goes, and files still in
use are reported as left over instead of stopping the uninstall (Windows).
Both from Reddit reports (2026-10-12).
bHaptics' vest SDK asks for BLUETOOTH_CONNECT at start; on Lepton's Android 11 the permission screen takes the
foreground for a moment and the game pauses (Yupitergrad froze on its loading screen in the reporter's session).
PermissionUtils.requestBluetoothPermission returns at once (Dex.return_early). Suggested by analysis
bhaptics_permission (ANALYSIS_VERSION 14) and triage bhaptics-permission-prompt. On the dev Frame the prompt is gone;
whether it was the whole cause of the freeze is for the reporter to confirm.
Opt-in game setting (Picture -> Draw fades over the picture). Batman: Arkham Shadow fades by dimming its projection
layer with XR_KHR_composition_layer_color_scale_bias; with fade_quad=1 FrameBridge adds a black, alpha-blended quad
right after the dimmed layer (VIEW space, 1 m ahead), opacity = 1 - scale in 16 steps. One 8x8 swapchain, refilled
only when the step changes (Vulkan clear on the app's queue / GLES clear in its context); one swapchain per step hit
XR_ERROR_LIMIT_REACHED. fade_quad=2 also removes the layer's own scale. Device (headless, Batman): swapchain created,
level 16/16 on the first frame, no xrEndFrame errors, 72 fps.
The game showed a canvas being painted as its own compositor layer, which the Frame draws in front of everything.
PaintableMesh.HasCompositorLayerAvailable and ShouldUseCompositorOverlay return false (Cpp2IL), so the game's own
fallback draws the canvas in the scene (Klownicle's finding). Catalog recipe, PLAYBOOK row, test.
No Cpp2IL release reads Unity 6.5's metadata yet ("We support 23-106, got 107"), so the text-field and MSAA
fixes were skipped for Wander 0.3570 (#198). When the release reports an unsupported metadata version, the
development branch's CI build (nightly.link, as Cpp2IL's README links it) is fetched into tools/cpp2il-nightly/
and used; cached errors of that kind get one retry with it. Checked with Wander 0.3570: it reads the v107
metadata and writes TMP_InputField, OVRDisplay and OculusLoader.
Bionic allows 128 pthread keys per process. Unity 6 takes about 40, and with Gecko, Firebase and the Frame's own
libraries Wander 0.3570 ran out: Firestore aborted at start ("cannot create thread specific key for
__cxa_get_globals()", #198, #202). Opt-in patch, suggested for Unity 6 with Firebase C++ or Gecko: libunity.so's
pthread_key_create/_delete and pthread_get/setspecific imports are renamed in place to fp_tkey_* (new
elf.rename_imports: undefined symbols only, shared names refused, versions set global) and libfp_tkeys.so
(native/tlskeys) is added to its DT_NEEDED; keys without a destructor become generation-tagged slots behind one
real key, everything else keeps real keys. Approach and the first helper by Klownicle (#198), reimplemented here.
Triage signature pthread-keys-exhausted, PLAYBOOK row, Wander's recipe updated to 0.3570.
Installs the new build and leaves the game data on the Frame as it is (the CLI's --apk-only): a normal update
re-sends every OBB whose size differs from the PC's copy, which replaced OBBs changed on the Frame (mods). Asks
first; Quest games on the Frame only. Resume after a failure keeps the kind of update.
New games are checked against the drive chosen on the Frame page, installed ones against their own drive, from
the drive list fetched at connect and after install jobs (app.frame_drives). Internal storage's free space only
counts when no drive list is known. drives.target_drive/space_shortfalls are pure helpers with tests.
Flet's Linux picker asks the XDG desktop portal; window managers without one (IceWM, bare X11) answer
NameHasNoOwner and every pick raised. C.pick_files / C.pick_dir now fall back to zenity or kdialog (kdialog
first on KDE; core/pickers.py, run off the UI loop), and without either to a "type the full path" box. All
twelve pickers go through them.
Agent 83: deployment.json desktop_icon (default on); refresh_desktop_entries only updates a desktop copy that is
there; desktop_entry takes icon=. Game page: "In the app menu" and "On the desktop" switches.
- Agent 83: Valve's Lepton pastes the game's paths unquoted into shell commands (liblepton mounting.sh), so a game on
a card named "Steam Frame 512g" never got its internal storage (no saves, no SharedPreferences). The Quest launcher
now links the game folder to ~/.local/share/frameport/lepton-paths/<pkg> at every start and gives Lepton that path;
upgrade_launchers converts existing launchers, move and uninstall handle the link (#213, #214, #215, #221).
- frame.eos_keychain_loop (opt-in, offered by triage): Epic Online Services' resetKeychain returns at once, so a
keychain it can't write no longer loops forever (Beyond Sandbox, #214).
- Triage lepton-data-link-failed and eos-keychain-loop.
- CryEngine also from libAndroidLauncher.so + a .cryproject (Climb 1, #238); ANALYSIS_VERSION 12.
- Plain words: patch titles lose bracketed internals unless Show technical details is on (C.patch_title); a passed launch test just says so, how far it got shows only when it fails (C.test_line); Frame page readiness says Quest games / PC VR games and storage drops the file system (reason in a tooltip); the failure pop-up says where it stopped, that Resume continues and that saves and signing keys are kept. Engine and VR API stay on the game page; the OpenXR runtime and game launch capacity checks stay; the first start still names its tools.
- Readable dim text: TEXT_3 is #868A96 (Portal, Portal OLED) and #868B9C (Original), at least 4.5:1 on the window, sidebar, cards and raised panels (was 3.6-4.4:1); a test keeps the built-in themes there.
- Quieter empty tabs: the not-connected Files, Screenshots, Live view, Type on Frame and Monitor tabs show one sentence and Connect above a faint sketch of the tab (C.ghost_preview) instead of three feature cards; the Live view shows one Start button and no feature cards.
- The connect page has one way in: "Set up your Frame" up front (no password, nothing changes until you allow it), "Already set up?" below, the address and password behind "Connect by address…"; no 1/2/3 numbers.
- Consistency: every switch is C.switch, with the portal gradient painted under a transparent track (the real Switch keeps keyboard, focus and semantics), a dark thumb with a check when on and a grey one with a cross when off (the same size); where a patch came from is blue information, not orange; the platform filter says "Quest/Android"; the welcome screen says "Set up your Frame".
- Showcase: the live-view shot waits for "Ready when you are"; the install video clicks "Set up your Frame".
- Section labels name what you do there ("See how it works", "See what runs", "Get started") instead of 01-07; plain headlines ("What happens when you click Install on Frame", "FramePort patches the games that don't run as they are"); the hero's eyebrow is gone; nav "Install" -> "Get started" (no clash with the /install/ link page)
- Phones and narrow windows (below 1120 px) get a Menu panel instead of a hidden or wrapping nav; on phones the download buttons say "Get it on your PC"; no three.js on data saver or 2G/3G; the install log drops its detail column under 600 px
- The download page says why Windows and macOS warn on first start (self-signed) and where the SHA-256 sums are; Get started step 3 says nothing changes on the Frame until you click Allow, with a link to the script
- The app tour's screenshots and videos sit behind one disclosure; the game-maker panel shows the demo button on its own stage with the HTML behind "Show the HTML"; Compare without icon tiles, Free and open source stays the emphasized card

`LoadLibrary("LibOVRRT64_1.dll")` search (exe dir, cwd, system32, windows, PATH — no registry, `OculusBase` or
`LIBOVR_DLL_DIR` used by this build) → `Failed to initialize Oculus API (-3001)` (= Lies Beneath's "Unable to load
LibOVRRT DLL"). A symlink `pfx/drive_c/windows/system32/LibOVRRT64_1.dll -> <base>/revive/LibReviveXR64.dll` (Wine
maps a symlink to the already-loaded module) gets past it to **-3021 = ovrError_LibSignCheck**: the shim only accepts
an Oculus-signed runtime. Next step (not done): make the runtime check pass without Detours, e.g. an injected helper
that patches the game's import table (IAT) for LoadLibrary*/WinVerifyTrust, or a prefix-level override. This is
runtime interop (what Revive does), not the Platform SDK licence check (which FramePort never touches).

**Steam Frame controller models (2026-09-30, not yet seen in a game):** adapter setting `controller_models`
(`native/adapter/render_model.c`) emulates XR_FB_render_model and serves `files/framebridge/controller_{left,right}.glb`;
(folder name matching "frame" + left/right, OBJ+PNG, `openxr_grip` component → grip space) at finalize/set_settings.
Valve's models are never committed or copied off the Frame. Only games that use Meta's runtime controller models
benefit (manifest `RENDER_MODEL` permission/feature → suggested); **none of the 34 catalog games do** (they ship their
own meshes: that would need per-game asset replacement). Model discovery and conversion
checked on the device 2026-09-30: `/opt/steamvr/drivers/frame_controller/resources/rendermodels/frame_controller_{left,right}`
(component OBJs in model space = the whole `<name>.obj`, one `_color.png` 2048² near-black, `openxr_grip` rotates about
X only; hidden-by-default components like `status` are skipped) → ~2 MB glb each, ~1 s. Not yet seen in a game (none
of the installed builds has the new adapter, and none requests runtime models), so whether Meta's SDK attaches runtime models at the grip pose is unverified.
**Steam Frame controller models:** adapter setting `controller_models` (`native/adapter/render_model.c`, emulates XR_FB_render_model) + agent `install_controller_models` (Frame's SteamVR models → glb at finalize); no catalog game uses runtime models; Valve's models are never committed or copied off the Frame. → docs/DEVICE_NOTES.md#steam-frame-controller-models
**overport's dispatcher (`libopenxr_loader.so`) only forwards functions in its own table** (`overportOXR: Unknown
proc addr: …`), so adapter emulations of functions it doesn't know are unreachable. For XR_FB_render_model,
`native/xrshim` fills the gap: OVRPlugin's `dlopen("libopenxr_loader.so")` string is rewritten to the shim (see
native/README). Verified on the device with Toy Master (2026-09-30): `extension shim: xrLoadRenderModelFB -> FrameBridge`.
Toy Master doesn't request a model after that (it uses its own), so the glb loading path is only unit-tested.
**Crash backtraces (2026-09-30):** Lepton writes tombstones only to `lepton-logcats/steamlaunch-<appid>/logcat-crash.log` (after "Dumping logcat"), not launch.log; agent v23 launch tests wait for it and return `crash_log`, triage gets it via `triage(..., crash=)` (not pid-filtered: tombstones come from crash_dump's pid). The guest is `userdebug` (`ro.debuggable=1`), so Lepton's Fossilize layer loads into every app whatever the APK's debuggable flag; it has no off switch. Fossilize crashed Deadpool VR on uninitialized attachment-reference pNexts (several, in FVulkanRenderPass and the render-target layout) → `frame.vk_sanitize` = `native/vkshim` (engine's `dlopen("libvulkan.so")` string → `libfp_vk.so`, wraps vkCreateRenderPass2/KHR, drops unreadable/wrong-sType pNexts; verified: game runs). overport's dispatcher aborts on swapchains > 4096 px (`cmp wN,#4096` in xrCreateSwapchain) → `frame.swapchain_limit` (verified with 4XVR, 7680×3840 accepted by the runtime). Both are default-on (parity classifies their rewrites as
"expected"; library migration `quest_binary_fixes_v2`). The adapter shows cylinder layers (4XVR's movie screen) as ~15° quad strips (`cylinder_strips`, setting
`cylinder_strips`); the runtime composites them at full resolution. Equirect (360°) layers are dropped: drawing
them ourselves (GLES renderer in xrEndFrame: stutter, never showed 4XVR's VR video; Vulkan renderer: hung the
Frame's GPU in AC Nexus; reading the newest *released* image broke 4XVR's theatre) was removed again on the owner's
request — don't retry without a new approach. Converted layers must count as "swapped" or the original layer list
is submitted (runtime returns -2 for every frame). A focus debounce (hiding the Frame's brief
FOCUSED→VISIBLE→SYNCHRONIZED dips, which make 4XVR recenter) was also removed: AC Nexus stayed black with it (it
hid 521 ms focus changes at start). The new approach (below) is per-game, off the app's render thread, GLES-only.
mounted in Lepton as `/data/steamvr/runtime`) only composites quad + projection layers (cube/cylinder/equirect(2)
are enum names only) — nothing to unlock. Per-game adapter settings (off by default, hooks installed only when on):
`equirect_emul` (GLES only: a worker thread with a shared EGL context converts each 360° image to a cube map when it
changes and draws one adapter projection layer from it for every frame with exactly that frame's views (the app's own
projection views, else xrLocateViews at displayTime); xrEndFrame waits ≤6 ms for the worker's CPU submit, never the
GPU. Learned in the headset: quads can't be a background (the Frame draws quad layers above all projection layers
whatever the order: hid 4XVR's balcony/controllers), and the Frame doesn't reproject a projection layer from its own
pose (images drawn only after head turns, or ahead from xrWaitFrame and sometimes late, wobbled);
`equirect_flip/face/res/fps/stereo`), `stable_local`, `focus_hold` (only after 3 s FOCUSED, dips <600 ms),
`aim_pitch/aim_yaw/aim_forward`, `refresh_rate`, `layer_debug` (diagnostics); focus_hold is default-on since 2026-10-05. 4XVR re-creates LOCAL spaces every 2–4 s
(menu recentring suspect); its theatres are baked 7680×3840 equirect2 images (`assets/100.png` …). Test 360° videos
(NASA, public domain) are in the Frame's ~/Videos; copies in `~/Downloads/frameport-360`. 4XVR's "Internal Storage"
lists its own `/sdcard/4XPlayer`, not Movies: agent v25 `link_media` hard-links sent files into an app's own top-level
never starts VR on the Frame (no OVRPlugin/OpenXR lines; runs as a 2D app), which is why its "controller setup"
screen can't be passed — Unity 2017's Oculus device check, not the controller profiles. Cpp2IL can't read Unity 2017.
The Frame's Android runtime (vrclient.so) knows oculus/touch_controller but not Meta's Touch Plus/Pro profiles
(OVRPlugin suggests those too, routinely) → adapter `profile_remap`.
Headset round 2 (2026-10-04): the Frame drops focus often (ms to 7 s; only some are presence/standby) → games pause
or recentre (B&S Player.OnVRPresence → Teleport, BattleGlide/Unreal pauses); focus_hold now 1 s focused / 1 s max dip
(longer must still pause). Myst crash = vrclient xrSyncActions race after FOCUSED → `sync_guard` (confirmed); its
object glitches: app space warp suspected (FB_space_warp is advertised and used) → recipe `patch_disable_space_warp`.
I Am Cat multipass: poses/times consistent, but every frame is submitted after the next xrWaitFrame (one period late;
Zink + doubled draws) and the game clamps its physics step to 10 ms → judder while still; testing scale 0.8. Roblox's
newest crash is on Fossilize's recording thread → vk_sanitize extended to own-engine libs (engine "Other").
Accounting+: unity_oculus_check + native/ovrpshim (libfp_ovrp.so waits via ovrp_WaitToBeginFrame before Unity
2017's ovrp_Update2) → VR in the headset at ~72 fps (2026-10-04), but stuck at "press any button" although input
reaches its OVRInput cleanly (probe: both Touch connected 0x63, individual buttons, input focus 1) → works with issues.
"outside of frame bounds" warnings stay (~2/frame) and are harmless.
Steam library (GitHub #4/#21/#27, agent v38): shortcuts go to every Steam account (signed-in first; MostRecent isn't
always the account on the Frame); stop_steam also waits for Steam's helpers; after the restart the agent re-reads
shortcuts.vdf and writes once more if Steam put its old copy back (`shortcuts_lost`), else reports it. 0.6.3's Play
auto-repair (`_add_then_play`) crashed (its job got a Job, not a reporter). Uploads resume on a transient OSError.
Lepton's Android 11 has no clipboard service (134 services; checked with `podman exec … service check clipboard`):
SDL/LÖVE apps crashed at start → `frame.sdl_clipboard` (`apk/dex.py`: in-place dex edit, nops one invoke, fixes
the header checksum/signature; verified with LÖVE for Android 11.5, GitHub #24 Dramatic Shape). Godot 4.2-4.4 (Kotlin `as ClipboardManager`,

clipboard methods return at once; analysis `godot_clipboard`, ANALYSIS_VERSION 10; checked on real godot-lib/templates
4.2.2-4.4.1, not on the device; 4.1 and 4.5+ don't throw). 2D apps (vr_kind none)

~/.local/share/frameport-app because ~/.local/share/frameport is the agent's) and Steam library changes wait while
Desktop Mode is open. Verified on the device 2026-10-04 (install + launch test from the Frame). Library updates on the
Frame run one at a time (agent v40 flock): two quick uninstalls used to bring a removed shortcut back (Roblox).
Headset round 3 (owner's verdicts, 2026-10-04): Blade & Sorcery works — its freezes were the headset's wear sensor
flickering off while worn (vrserver.txt "HMD off/on" 0.5-2 s) → per-game `focus_hold_ms=2500` (only this game reacts;
not a default). BattleGlide works (focus_hold). Myst works with issues (object glitches; space warp ruled out, its
recipe keeps it on). I Am Cat works with issues (judder; scale 0.8 no help). Roblox unsupported (je_free in
libroblox, also with the Vulkan shim). Installs skip the Steam restart when the shortcut is unchanged and wait while a
game runs (agent v37). New default fixes in FramePort's code reach games already in a library: after every app update
`library._follow_catalog` re-derives each non-user recipe once (setting `recipes.app_version`; tests switch it off via
`library.REFRESH_ON_UPDATE`). Analysis fields added later: **bump `analysis/detect.ANALYSIS_VERSION`** (stored as `analysis.extra.analysis_version`); older entries whose APK is still there are analysed again at the GUI's start (background thread, not a job: ~8 s per 900 MB APK) and before a build (`pipeline.refresh_analyses`, GitHub #104); only `analysis`/`suggested` change, user recipes stay; an unreadable APK gets `analysis_failed` = the version (not retried until the next bump). Troubleshooting techniques: docs/PLAYBOOK.md "Debugging techniques". Unity `boot.config` "vulkan" substring mislabels GLES games as Vulkan
(I Am Cat ran GLES); OVRPlugin's "Unavailable OpenXR extension: XR_FB_scene" is routine (no longer triaged).
**Round 4 (2026-10-04):** XR_KHR_android_surface_swapchain is listed by the Frame's runtime but returns
FUNCTION_UNSUPPORTED → adapter `surface_emul` (default on, `native/adapter/surface_swapchain.c`): an ordinary runtime
swapchain is returned, the game gets a Surface from a SurfaceTexture on a worker thread (own EGL context, JavaVM from
XrInstanceCreateInfoAndroidKHR), frames are read back (glReadPixels) and uploaded in xrEndFrame (Vulkan: own command
buffer + fence per panel, never waits; GLES: glTexSubImage2D). I Am Monkey's intro works (owner-confirmed). SUPERHOT
(Quest) quit at start: its cloud save folder was mode 1700 and Lepton's app writes through the folder's group →
DATA/ → external files/WiiCompiledOpenXRVR/DATA, MOD/ → .../RetroRewind6 (decompiled with jadx). Lepton has no
picker at all: a FramePort fix would be an injected picker activity. Generated cover/banner art used to suppress the
Steam placeholder set (no Steam art at all) → fixed in artwork/steam.py.
**Steam library failures (GitHub #21/#30):** on some Frames Steam never loads FramePort's shortcuts.vdf entries (same SteamOS build and arm64 beta client as the dev Frame; IDs correct; file written before Steam starts): Play → console_log `GameAction [AppID <id>] … RequestingLicense → UpdatingAppInfo → LaunchApp failed with AppError_9` (= "Game configuration unavailable", Steam treats the id as a store app). Cause unknown; agent v42/43 diagnostics: `launch` returns `steam` (started / error + code / silent from console_log), `collect_diag` adds `steam_library` (real Steam dir, beta, Steam start vs vdf write time, entries per account, devkit games) + `steam-console.txt` (incl. Steam's `logs/shortcuts.previous.txt` if present; steamclient.so has "LoadShortcuts: rejecting attempt to load shortcuts: invalid account ID"). **Fallback (agent v43):** when Play gets AppError_9 the agent registers the game through Steam's devkit interface (what Valve's Devkit Management Tool does, MIT: `devkit-1 steam://devkit-1/<~/.steam/steam.token>/create-shortcut?response=<file>&gameid=<id>&directory=~/devkit-game` written to ~/.steam/steam.pipe; answer file / `.error`; `~/devkit-game/<id>/launch.sh` = link to the game's launch.sh, `<id>-argv.json` ["launch.sh"] (relative to the folder), `<id>-settings.json` {steam_play 0, compat_tool ""}). Steam adds it live (no restart), picks its own appid (read back from shortcuts.vdf by DevkitGameID), shows it as a normal non-Steam game named "Devkit Game: <id>" (OpenVR 0, but VR works: owner-verified 2026-10-04), art copied to grid/<appid>*. Ids: letter first, then letters/digits/_ only (spaces, '-', leading digit → "missing/invalid arguments"). Later Plays use the devkit entry; uninstall (`devkit_unregister`, `delete-shortcut` live) and purge remove it. Verified on the dev Frame: register/launch/unregister; the AppError_9 trigger itself only in unit tests. GitHub #42 (two Steam accounts, neither MostRecent): Steam rewrote the active account's shortcuts.vdf without FramePort's entries right after starting, and added the devkit entry live without saving it, so `devkit_appid` (vdf only) failed ("Steam added the devkit entry but didn't save it"); agent v55 `devkit_appid_from_log` reads Steam's `sanitize shortcut app id "~/devkit-game/<id>/launch.sh": replacing 0 with N` console line. GitHub #41 (one account): same Steam behaviour, and every install restarts Steam, which forgets the never-saved devkit entry. Agent v56: the log fallback reads only the current session's console_log.txt; Play re-registers a devkit entry that gets AppError_9; art updates also write the devkit entry's grid art (`copy_grid_art`). Open: why some Frames' Steam never loads or saves shortcuts.vdf (single account too).
**Exit game (GitHub #36, 2026-10-04):** `Apps.TerminateApp` (what Exit game calls; reachable for tests through Steam's CEF devtools on 127.0.0.1:8080, SharedJSContext, `Runtime.evaluate` — a stdlib websocket client is enough) closed both a normal shortcut and a devkit entry on the dev Frame within 1-3 s. SIGTERM to Steam's `reaper` alone left launch.sh + Lepton (setsid) + the container running (an earlier headset launch ran on for 87 min); SIGTERM to launch.sh cleans up in ~4 s. Agent v44: launch.sh's 2 s loop ends the game when its parent (the reaper) is gone; `upgrade_launchers` (from ensure_host_fixes) adds that to existing launchers in place. Which in-headset exit path fails is still unknown. Screenshots on the Frame: all under SteamVR's appid 250820 (`760/remote/250820/screenshots`, screenshots.vdf has creation time, no game).
**SteamVR dashboard at game start (2026-10-04):** the dashboard (Resume game / controller / VR options) was open whenever a FramePort game started (also over Lepton's 2D launcher). Steam's UI exposes `SteamClient.OpenVR.VROverlay.{IsDashboardVisible,HideDashboard,ShowDashboard}` (CEF devtools, `steam_js` in the agent). Agent v44: launch.sh starts `_dashboard_worker` (waits for FrameBridge's first `pacing:` line in launch.log, then hides a visible dashboard for 25 s, at most 3 times; log `<base>/dashboard.log`; opt out with env FRAMEPORT_KEEP_DASHBOARD=1). Verified on the dev Frame (dashboard shown → 4XVR launched via Steam → hidden ~5 s after the first frames); not yet seen in the headset. **Headset (ITR2, 2026-10-05): too late** — Steam shows its frame menu (`valve.steam.gamepadui.frame.menu`, vrwebhelper_systemui.txt `[PooledPopups] Showing`) ~0.3 s after the game's first submitted frame (FrameBridge `new layer:`), but the first `pacing:` summary comes ~8 s later; the owner had pressed Resume (`[HideDashboard] return_to_game`) before the worker looked. Agent v52: watches from the first `new layer:` line (incremental log reads, 0.5 s polls, 30 s window). Agent v59: watches 120 s and hides up to 10 times (the menu came back after 30 s in the owner's sessions). Agent v53: stops for good once the player opens the dashboard with the controller (`toggle_dashboard_action` in vrwebhelper_systemui.txt since the worker started): v52 closed it 60 ms after each press, and the game, paused for it, stayed paused.
**Space warp / ITR2 (2026-10-04):** Into The Radius 2 (UE5, `libUnreal.so` + OVRPlugin, Vulkan) uses Application SpaceWarp (extra swapchains `376x376 format=97` motion vectors + `format=129` depth); #35 reports flickering textures. OVRPort's `patch_disable_space_warp` has no effect on UE5, and hiding XR_FB_space_warp in FrameBridge's enumerate doesn't reach the game either: **OVRPort's dispatcher offers/enables XR_FB_space_warp itself**. FrameBridge `hide_space_warp` (per game, off) hides it and strips `XrCompositionLayerSpaceWarpInfoFB` (1000171000) from the projection views (log `hide_space_warp: removed space warp info`); the game still renders its MV swapchains. Test build installed on the dev Frame; flicker not yet checked in a headset. Heuristic: UE5 + OVRPlugin shows it as an option (off). `equirect_emul` is suggested for Unreal games whose graphics API isn't detected ("GLES or unknown"); on Vulkan it switches itself off (Myst/Riven/ITR2): harmless, but Unreal Vulkan detection is a known gap.
**PR #34 (merged 2026-10-04, Lucas-Mathieu):** `native/adapter/audio_metadata.h` patches Meta XR Audio Wwise (only build ID e1619e7f…, Batman: Arkham Shadow 1.4.1) so queued audio metadata isn't freed while the current audio frame references it (smoke-bomb crash). Verified headless: installs ("metadata reclamation follows …"), 72 fps; we added a once-per-second scan limit. Outside PRs: review source, rebuild `artifacts/` ourselves, merge locally (contributor's commit kept), push main.
**Crash backtraces:** Lepton writes tombstones only to `lepton-logcats/steamlaunch-<appid>/logcat-crash.log` (launch tests return `crash_log`). Fossilize loads into every app (userdebug guest) → `frame.vk_sanitize` (`native/vkshim`); overport's dispatcher aborts on swapchains > 4096 px → `frame.swapchain_limit`; cylinder layers → quad strips (`cylinder_strips`). Drawing equirect layers ourselves and a focus debounce were tried and removed: don't retry without a new approach. → docs/DEVICE_NOTES.md#crash-backtraces-fossilize-swapchain-limit-cylinder-and-equirect-layers
**360° layers / 4XVR:** the Frame's Android runtime composites only quad + projection layers (quads always above projection layers). Per-game adapter settings (off by default): `equirect_emul` (GLES), `equirect_flip/face/res/fps/stereo`, `stable_local`, `focus_hold` (default on), `aim_pitch/aim_yaw/aim_forward`, `refresh_rate`, `layer_debug`; agent `link_media` / `app_media_dirs` put sent files into a player's own folder. → docs/DEVICE_NOTES.md#360-layers--4xvr
**Companion apps / intents:** a second APK can run inside a game's Lepton container, but Lepton turns every `android.intent.action.VIEW` with data into `steam://openurl` → "open in external player" hand-offs can't work; Lepton installs exactly one `*.apk` per app folder. → docs/DEVICE_NOTES.md#companion-apps--intents-stremio--4xvr
**Text input:** Lepton's Android has no IME and VR apps run headless (no focused window); `lepton-show-flatscreen` keeps VR and gives focus + Steam's keyboard (`device.text_input_window`); `frame.unity_text_input` patches Unity's TMP_InputField/InputField at Cpp2IL offsets; agent `_keyboard` = uinput "Type on Frame". `pm install` of a second APK corrupts the main app (`cmd_real package install` skips the hook). → docs/DEVICE_NOTES.md#text-input-stremio-vr
**User reports #4-#10:** shortcuts go to the signed-in account (agent `library_users`), `launch` errors `NOT_IN_LIBRARY`; shared Cpp2IL run (`unity_text_input.Il2cppReturnPatch`) for `frame.unity_runtime_msaa_off` and `frame.unity_multipass`; VR4 → catalog `use_alt`. **Catalog changes reach existing games**: recipes store `catalog_rev`, `library._follow_catalog` re-derives non-user recipes. → docs/DEVICE_NOTES.md#user-reports-2026-10-04-issues-4-10
**Round 2 of reports / headset rounds 2-3 (2026-10-04):** vkshim `vk_shader_fix` (VR4); `Il2cppReturnPatch.field_loads` (I Am Cat); builds record `recipe_fp` (changed recipe/revised patch → "Update on Frame"); `Frame.relocate`; adapter `profile_remap` (Touch Plus/Pro); `sync_guard` (Myst); `focus_hold` tuning; ovrpshim for Unity 2017 (Accounting+); Steam library to every account, `shortcuts_lost` / `add_devkit_entry`; no clipboard service → `frame.sdl_clipboard`, `frame.godot_clipboard`; 2D apps keep non-VR patches (`needs_vr = False`); `frame/local.py` (FramePort on the Frame); after every app update `library._follow_catalog` re-derives non-user recipes once (`recipes.app_version`, `library.REFRESH_ON_UPDATE`). Analysis fields added later: **bump `analysis/detect.ANALYSIS_VERSION`** (re-analysis at GUI start + `pipeline.refresh_analyses`; `analysis_failed`). Roblox and BONELAB crash (unsupported). → docs/DEVICE_NOTES.md#round-2-of-reports-headset-rounds-2-3-2026-10-04
**Round 4:** XR_KHR_android_surface_swapchain is listed but unsupported → adapter `surface_emul` (default on, `native/adapter/surface_swapchain.c`); save folders without u/g+rwx → launch.sh `fix_perms`; Lucky's Tale OOM (no fix); `perf` works as steamos (gdb blocked); QuestCraft JRE, WiiCompiled import by hand (Lepton has no document picker). → docs/DEVICE_NOTES.md#round-4-2026-10-04-surface-swapchains-save-folder-permissions
**Steam library failures (GitHub #21/#30/#41/#42):** on some Frames Steam never loads FramePort's shortcuts.vdf entries (Play → AppError_9) → fallback: register through Steam's devkit interface (`devkit-1 … create-shortcut`, `~/devkit-game/<id>/`; `devkit_appid`, `devkit_appid_from_log`, `devkit_unregister`, `copy_grid_art`; ids: letter first, letters/digits/_ only); `collect_diag` adds `steam_library`. Cause still unknown. → docs/DEVICE_NOTES.md#steam-library-failures-and-the-devkit-fallback-github-21304142
**Exit game (GitHub #36):** `Apps.TerminateApp` (Steam CEF devtools on 127.0.0.1:8080) closes games; launch.sh ends the game when its parent reaper is gone (`upgrade_launchers` adds it). → docs/DEVICE_NOTES.md#exit-game-github-36
**SteamVR dashboard at game start:** launch.sh's `_dashboard_worker` hides the dashboard via `SteamClient.OpenVR.VROverlay` (agent `steam_js`) from the first FrameBridge `new layer:` line (120 s, ≤10 times, stops after `toggle_dashboard_action`); log `<base>/dashboard.log`, opt out `FRAMEPORT_KEEP_DASHBOARD=1`. → docs/DEVICE_NOTES.md#steamvr-dashboard-at-game-start
**Heuristics eval (2026-10-04):** 19/44 recipes exact (superseded by the 2026-10-15 numbers under Heuristics). → docs/DEVICE_NOTES.md#heuristics-eval-2026-10-04
**Power (0.9, agent v47):** sidebar bar below the Frame card: Sleep / Restart / Shut down, each confirmed (`app.frame_power`, a running game asks again). logind answers CanSuspend/CanReboot/CanPowerOff = "challenge" for an SSH session but "yes" inside a user unit, so agent `power` runs `systemctl suspend|reboot|poweroff` from a transient `systemd-run --user --on-active=3` timer (the command answers first). Restart verified on the device (back in ~84 s, new boot id).
**Proton default (agent v51, owner's choice 2026-10-05):** the newest **stable** ARM64 Proton is the default for PC VR games (`pick_proton`: asked-for name/alias, else newest installed stable, else any stable). Agent v49-50 defaulted to Experimental; the owner's headset A/B with Rick and Morty (Experimental 69 % reprojected frames, stable felt much smoother) reverted it. The game page's Customize shows `pcvr.proton_tool` as a dropdown (Stable (default) / Experimental = alias `proton-experimental`); `ensure_proton` installs a chosen one (it asks once more for the runtime Steam only names after Proton is installed; Experimental installed unattended on the device in 53 s). A PC VR launch test that fails on stable suggests Experimental (`pipeline.PROTON_TOOL`, `proton_alternative_worth_trying`, button "Try Proton Experimental and reinstall"). Remaining Rick and Morty stutter on head turns = the game rendering below the refresh rate (reprojection), not Proton.
**USB cable link (verified 2026-10-05, cabled to the dev PC):** `usb0` is a USB **NCM** gadget (configfs g1: `ncm.usb0` + `ffs.adb`, Valve 28de:2460) set up by `usb-ncm-gadget@usb0.service`, which only runs with `ConditionPathExists=|/etc/systemd/system/adbd.service.d/steamos-devkit-enabled` = **Developer Mode only**. `usb-ncm-dnsmasq@usb0` serves DHCP with fixed `dhcp-host` entries: Frame 10.86.200.233, PC **10.86.200.234** (`frame/usb.py` FRAME_USB_IP/PC_USB_IP). Windows 11 binds its built-in "UsbNcm Host Device" (no driver); WSL mirrored sees eth 10.86.200.234. USB is high-speed (USB 2.0): upload 36.9 MB/s vs 11.3 MB/s home Wi-Fi. Frame→PC over the cable worked without a firewall change. `scripts/usb_autotest.py` (Windows via powershell.exe from WSL), `frameport frame usb-check`. Wizard "Set up with a USB cable" (`PairingServer(host=PC_USB_IP)`; the real bootstrap ran end to end over USB). Discovery dedupes by SSH host key and prefers USB > Frame hotspot > network (`discovery.dedupe`); a lost address is re-found by key (`Frame.relocate`, tested with a dead saved address).
**USB cable link:** `usb0` is a USB NCM gadget (Developer Mode only); Frame 10.86.200.233, PC **10.86.200.234** (`frame/usb.py`); ~37 MB/s; `scripts/usb_autotest.py`, `frameport frame usb-check`; discovery prefers USB > hotspot > network (`discovery.dedupe`). → docs/DEVICE_NOTES.md#usb-cable-link
**Catalog updates without a release (2026-10-05):** apps fetch `catalog/games/*.yaml` from GitHub `main` (`recommend/catalog.refresh_remote`: one API call `git/trees/main?recursive=1` + raw.githubusercontent downloads of changed blobs, cached as `catalog-gh-<sha>.yaml`, every 6 h; GUI at start + Settings → Data "Check now"; CLI background thread + `frameport catalog-update`). `catalog.load()` only reads the cache. A remote entry is skipped (`unusable_reason`) when it names a patch/adapter key this app doesn't register, has a field `CatalogEntry` doesn't know, or `min_app` > this version: add `min_app` (or rely on new patch ids) when a config needs an unreleased FramePort. Remote beats bundled unless the bundled entry has a later updated/verified date; the user's own entries still win as before. Off: setting `catalog.auto_update`, env FRAMEPORT_NO_CATALOG_UPDATE; FRAMEPORT_CATALOG_URL still overrides the source. So: **pushing a catalog change to main reaches users within 6 h** (their recipes follow via catalog_rev → Update on Frame).
**Start activity / QuestCraft / ITR2 pop-in (2026-10-05):** WiiCompiled's VR part (`QuestActivity`, SDL, process `:game`) stays behind Lepton's flat window when the launcher is shown (`device.text_input_window`). `frame.start_activity` (opt-in; analysis `extra.vr_activity` = the original APK's activity with Meta's VR category when it isn't the launcher) gives that activity's filter LAUNCHER and every other LAUNCHER becomes INFO, per element (`axml.set_start_activity`); Lepton's own `apk-info-extractor --print-activity-name` (on the Frame under Lepton/liblepton/apk_extractor) then answers QuestActivity. **OVRPort gives every MAIN activity LAUNCHER + VR categories**, so the VR activity must come from the original APK's analysis, not the converted manifest. Lepton has no activity override (`APP_ACTIVITY` is reset when app_metadata.sh is sourced). QuestCraft reaches Minecraft 1.21.5 (Fabric, Vivecraft, Sodium; LTW "Large Thin Wrapper" GL 3.0 on the Frame's Zink) and stops at `OpenGL error 1282` in `WindowFramebuffer` createTexture (Minecraft's crash report in `files/instances/1.21.5/crash-reports/`, Pojlib's `files/latestlog.txt`); the vrclient SIGSEGV / "pthread_mutex_lock called on a destroyed mutex" afterwards is only the shutdown (Unity's render thread still in vrclient while the instance is destroyed). ITR2 "models popping in and out" in game: Unreal reads user config from **internal** storage (`lepton-data/internal/<pkg>/files/UnrealGame/<Project>/<Project>/Saved/Config/Android/Engine.ini`, not external); `r.AllowOcclusionQueries=0` there broke its menus (removed again). Vulkan shim `vk_query_slots` (two slots per occlusion query) never saw ITR2 create an occlusion query pool, and the run with it crashed (Unreal RenderThread SIGSEGV, caught by sentry-native: no tombstone; the backtrace is in `cache/sentry/*/.sentry-native/*.run/*.envelope` with module offsets) - left off. Next suspect: Unreal 5 mobile HZB occlusion reading depth stored with Valve's FDM injection layer; test = launcher `VK_INSTANCE_LAYERS=''` (Lepton then loads neither VALVE_rpo nor VALVE_fdm_injection, Fossilize still). QuestCraft: LTW overrides glGetError and returns 0 with `LIBGL_NOERROR` set; Lepton passes `LEPTON_ENV_<NAME>` to the app as `<NAME>`, so catalog `lepton_env: {LEPTON_ENV_LIBGL_NOERROR: '1'}` gets Minecraft past the GL error 1282; then black picture (see the catalog entry). FrameBridge logs `new layer` once per layer type per process and projection views only for the first frames, so a second session in the same process (Vivecraft after Unity) needs `layer_debug=1`.
**Vulkan validation / ITR2 solved (2026-10-05):** Khronos' validation layer can't come from Lepton (its layer dir is in the read-only guest image; the Linux copies on the Frame are glibc) and a global `debug.vulkan.layers` property (via the LEPTON_GFXRECON_FP_PROPS trick) kills the container at boot. Working recipe: bundle `libVkLayer_khronos_validation.so` (Khronos android-binaries release, arm64-v8a, stored uncompressed) into a test APK re-signed with the game's key (`apk.sign.sign`), install with `frameport install <pkg> --apk`, and set the Vulkan shim's `vk_validation=1` (it adds the layer at vkCreateInstance; findings under the logcat tag VALIDATION in launch.log, each message ID capped at 10). ITR2's flicker + windows behind models = Unreal's Qualcomm shader-resolve subpasses with a depth resolve of a single-sampled depth attachment (VUID-04908/-03179); `vk_spec_fixes=1` drops that resolve (its TRANSFER_DST half never applies to ITR2: the main depth is transient). Valve's VALVE_rpo layer removed ITR2's fog (catalog `lepton_env: VK_INSTANCE_LAYERS: VK_LAYER_VALVE_fdm_injection`). `r.ViewDistanceScale=2` in the internal Saved/Config/Android/Engine.ini only exists on the owner's Frame (the catalog can't write internal storage yet). Launch tests: Lepton prints a transient "is not a running context" on the first start after an APK change (agent v54 `not_started` waits 30 s for "Boot complete!").
**GitHub #38/#39 (2026-10-05):** PowerWash Simulator stuck at "Waiting.." on a reporter's Frame = Unity sized the right-eye image rect past its swapchain (rect 268+1656 on a 1920-wide swapchain; the runtime's recommended size differs per Frame) and SteamVR rejected every frame (`xrEndFrame failed -25`, XR_ERROR_SWAPCHAIN_RECT_INVALID), after which the game stopped calling xrEndFrame. FrameBridge `rect_clamp` (default on; sizes noted in xrCreateSwapchain; clamped layers count as swapped) keeps projection/quad rects inside their swapchain; triage `swapchain-rect-invalid`. Not reproducible on the dev Frame with `scale` (Unity's eye sizing isn't just the recommended width); no regression there (72 fps). The adapter's revision was NOT bumped (that would mark every installed game outdated): affected users rebuild. The Room VR (#38) = Unity's render thread SIGSEGV in libgallium_dri.so ~30 ms after the game recreates its eye swapchain with samples=4 (FrameBridge retries samples=1); the game's own code turns MSAA on (not OVRManager); candidate fix: hide GL_EXT_multisampled_render_to_texture (GL shim) - needs the APK to test. The launch test passed both (render thread dead / no frames): triage gap.
**Headset round 2026-10-05 (evening):** I Am Cat's judder = repeated xrLocateViews of one display time returning
slightly different poses → FrameBridge `pose_consistency` (owner-verified, works). Lucky's Tale freeze on touching a
save slot = OVRPort's OpenXR dispatcher converting XR_FB_haptic_amplitude_envelope with ns read as s (GitHub #9) →
xrshim `haptic_fix` (owner-verified); its remaining short pauses were the wear sensor ("HMD off/on" 0.5-1 s in
`logs/eyetracking.txt`, not vrserver.txt) → **`focus_hold` is on by default with 5 s** (owner's choice; C defaults
too). The Room VR works (`unity_no_overlay_copy`). BattleSisters (Unity 2019.4 built-in VR, no libOculusXRPlugin.so)
flooded "outside of frame bounds" ~2400/s and hung the GPU (kernel hangcheck, zink DEVICE LOST) → the ovrpshim frame
wait now also applies to Unity 2019 without the Oculus XR Plugin (`UnityOculusCheck.legacy_loop`). Vader Immortal
(UE4, stuck on the loading image after the intro, GitHub #49): VRP repacks carry a Frida gadget (`libfrda.so`,
config `hijack_responses`), but OVRPort's `patch_clean_up_frida` removes its loadLibrary call, so it never runs on
the Frame; `frame.ovr_trace` (opt-in, `native/ovrtrace`: 1138 exported ovr_* stubs → real loader functions, logcat
tag `fp_ovrtrace`: calls, PopMessage answers, unanswered requests every 10 s) is the next diagnostic.
2026-10-06: buttons work. Its first controller vibration then hit OVRPort's haptic-envelope bug (11 GB, OOM kill) →
`haptic_fix` is now suggested for every game with libOVRPlugin.so (settings detect), BattleSisters works. Ruled out before: ProductName, GetNodePresent, the device-model string itself, exports.
Accounting+ works (owner, 2026-10-06).
**Vader Immortal (UE4, GitHub #49, 2026-10-06, headless):** stuck after the intro on an in-game image (the splash
quad ends ~6 s in; then the game's own projection frames, 72 fps, balanced xrBeginFrame/xrEndFrame). Not the Platform
SDK (`frame.ovr_trace`: only user + entitlement, both answered) and not the repack's Frida gadget (OVRPort's
`patch_clean_up_frida` removes its loadLibrary). It **leaks ~430 GPU mappings (/dev/dri/renderD128) and ~20 MB a
second** (6.5 GB + swap after 5 min, then 26 fps): page-fault stacks (perf -e page-faults, offsets resolved with the
process maps + vrclient.so's own symbols; its text segment is at file offset + 0x4000) end in SteamVR's runtime:
layers (VK_INSTANCE_LAYERS=""), array swapchains in general (Lucky's Tale/I Am Cat flat). Kernel tracepoints aren't
allowed for steamos. FrameBridge: `layer_debug` logs xrDestroySwapchain and per-5 s xrBeginFrame/xrEndFrame counts;
`frame_balance` (ends an open frame before the next begin) exists but Vader never leaves one open. Next (built,
not yet run: the Frame slept): `layer_debug` also counts xrAcquire/Wait/ReleaseSwapchainImage per 5 s (hooked only
with layer_debug, after the other conditional hooks) to see whether Vader skips a wait or release: it doesn't (361/361/361 per 5 s).
FrameBridge `snapshot=N` (`snapshot_gl.c`, GLES): every N s the left-eye image the game submits is read back on its
own context and saved as `files/fb_snap_0-7.ppm` (quarter size) — headless launches show a black headset view, this
shows what the game draws. Vader: Lucasfilm logo (an OBB mp4: video works), then its loading card (portrait + segmented
bar) that never advances; the async loader thread sleeps and OBB reads stop (~168 MB of a 2.7 GB pak).
**SteamVR overlay apps (agent v75, 2026-10-10):** host OpenVR overlays (VRApplication_Overlay) are composited over Lepton (Quest) games on the Frame (probe checker seen over 4XVR in the headset view, `native/vroverlay_probe`); Windows ones register through Proton's vrclient too (Temporal Reality's Windows build created its overlays; fpsVR never reaches OpenVR under Proton). Detection `analysis/vroverlay.py` (bundled `.vrmanifest` with `is_dashboard_overlay`, else OpenVR + IVROverlay + self-registration markers, engine Other; Rift fingerprint `RIFT_ANALYSIS`), patch `pcvr.vr_overlay` (param autostart), Linux entry fields `vr_overlay`/`vr_overlay_autostart` (game page switch); agent `register_vr_overlay`/`unregister_vr_overlay`/`launch_vr_overlay` (IVRApplications via ctypes, live; manifest `<anchor>/frameport-overlay.vrmanifest`, the app's own key, binary = launch.sh). **SteamVR on the Frame reads only `binary_path_linux_arm`** (binary_path_linux alone is skipped). Overlay apps: no launch test, no Linux Steam-parent watchdog (`FRAMEPORT_OVERLAY`), not a "running game". A Steam overlay-app shortcut and a game shortcut run together. SteamVR's SetApplicationAutoLaunch didn't persist on the dev Frame (the watch never started by itself) → **agent v76: FramePort's own autostart**: the deployment's `overlay.autostart` is the source of truth; `ensure_host_fixes` (`ensure_overlay_service`) keeps the user service `frameport-vr-overlays.service` (`_vr_overlay_watch`, 5 s polls of the known vrserver's /proc stat) only while an overlay app has autostart on (register/unregister, uninstall, purge and the kill switch `~/.local/share/frameport/vr-overlays.disabled` / `FRAMEPORT_NO_OVERLAY_AUTOSTART` update it); a new vrserver (pid + start time, kept in `~/.cache/frameport-vr-overlays.json` across agent updates) → child `_vr_overlay_round`: wait for IVRApplications, 15 s grace, `launch_vr_overlay` for apps not running (folder process or GetApplicationProcessId); log `~/.local/share/frameport/vr-overlays.log`. Dev Frame: adopted the running vrserver, skipped the already running watch; a start after a real SteamVR start/boot is not yet seen. Details: docs/FRAME_RUNTIME.md "Overlay apps".
**Lepton's logcat mirror dies (agent v67, 2026-10-09):** occasionally launch.log ends with `logcat: Unexpected EOF!` right after the game starts (about 1 launch in 50, Lepton 2.8.14 and 3.0.5): no dashboard auto-hide, no launch-test result. launch.sh's `_logcat_keeper` then reads `podman exec lepton-steamlaunch-<appid> logcat` itself into launch.log (up to 5 restarts while the game runs).
**Double launch (agent v57, 2026-10-06):** a second Play while Lepton still boots (~10 s with nothing to see) made
the second Lepton stop the first one's container ("Waiting for steamlaunch-<appid> (PID …) to exit", exit 137
"(starting)", "Clearing baked app data due to early exit") and both died (Vader, BattleSisters). launch.sh now takes
`flock` on `<base>/.launch.lock` (fd 9, inherited by Lepton; the watchdog and dashboard helpers close it with
`9>&-`); a second launch exits 0 and logs to `<base>/launch-dup.log`. `upgrade_launchers` adds it to existing
launchers. Verified on the device (second launch during boot: ignored, the first kept running). Vader on its loading
card ignores input too (owner pressed/held every button: presses reach the runtime, the card never changes).
**Issue triage round (2026-10-06, owner's headset):** vibration in OVRPlugin games = 2 s vibrations updated per frame and
stopped with amplitude 0; FrameBridge turns amplitude 0 into xrStopHapticFeedback (else each buzz ran 2 s), haptic_fix
uses the envelope RMS (was its peak), per-game `haptic_scale` → Creed/The Boys/Jurassic World fine. Lambda1VR (TBXR):
loader named by Build.MANUFACTURER (`frame.tbxr_vendor`), no graphics extension enabled (FrameBridge adds
XR_KHR_opengl_es_enable + asks for the requirements on -50), always multisampled render-to-texture (GL shim gives
single-sampled stand-ins when GL_EXT_multisampled_render_to_texture is hidden) + its xash/ data → works. Jurassic World:
`frame.vrapi_stub`. Metro Awakening: contributor's vkshim fixes + hide_space_warp + no VALVE_rpo (jumping polygons like
ITR2). Pinball FX VR: hide_space_warp (stutters). Eleven: a Meta online request fails after platform init → needs Meta
services. Star Wars Tales: top half black + freeze after loading; ruled out: asset-file paks (never requested), Valve
foveation (off: no change), GL errors (MESA_DEBUG=1: none), EGL_BAD_ACCESS once in OVRPlugin init (harmless); the game's
eye image reads back black. BlazeRush: VrApi bridge exports + ovr*_ToString stubs + avatar stub get it to the menu room
at 72 fps, full input reaches it (diagnostics `input 5s`: Touch type only, sticks 1.0, buttons, poses 0x8f), but the room
draws no controllers and ignores input; avatar loader forced to its "Failed" path (no logged-in user) changed nothing.
`frame.ovr_trace` can't trace Unity games (P/Invoke dlsym; nothing imports ovr_*). Headless: the VrApi bridge's 30 s
head-pose deadline ends VR mode without a worn headset (not a game bug).
**Lepton storage (2026-09-30):** each app's /sdcard (= /storage/emulated/0 → `<base>/lepton-data/external`) has `Movies`/`Download`/`Documents` symlinked to the Frame's `~/Videos`/`~/Downloads`/`~/Documents` (liblepton/mounting.sh, only if they exist at start); agent v24 `storage_targets` reads that mapping. Android's MediaProvider canonicalises paths to /home/steamos/... and rejects every file ("doesn't appear under [/system/media...]"), `sm list-volumes` is empty: the media index never works, apps must browse folders. Lepton installs with `adb install -g` (runtime permissions granted, MANAGE_EXTERNAL_STORAGE too). Files: `install/files.py`, `frameport frame send|storage`, GUI Files tab (formerly Frame → Send files).
**SteamVR per-app settings (2026-09-30):** editing steamvr.vrsettings while SteamVR runs is lost; the web API (127.0.0.1:27062 /app/setsettings) needs `x-steamvr-secret`. `native/vrsettings` = `fp_vrsettings.exe` (freestanding, OpenVR `FnTable:IVRSettings_003` as a Utility app, loads SteamVR's bin/win64/openvr_api.dll) sets them live and SteamVR persists them: section `steam.app.<shortcut appid>`, keys `preferredRefreshRate` (float) and `motionSmoothingOverride` (0 global, 1 on, 2 off, 3 always). Steam Link (vrlink) lists the Frame's rates 72/80/90/96/108/120/144 in vrserver.txt and follows the per-app preference ("host preferred N Hz"; whether the key is honoured is unverified in-headset yet). Judder metric: vrcompositor.txt session summary dropped + "Timed out. N total" (Stormland: 0 dropped but 313 timeouts in 2 min); fpsVR (`%LOCALAPPDATA%\fpsVR\*.json`, 0.1 ms histograms) gives p99 CPU/GPU ms. `pcvr.steamvr_tuning` (default on, PC only) applies on Play: highest rate whose budget ≥ p99×1.05, at least one step down, smoothing on.
**Language packs (merged from PR #20, 2026-10-04):** overport's `libovrplatformloader.so` is a dispatcher that `dlopen`s Meta's own loader (`libovrplatformloader_meta.so` / `_meta_q1.so`, also `libpxrplatformloader.so`) and keeps its own message queue; `ovr_LanguagePack_GetCurrent/SetCurrent` are 8-byte `return 0` stubs in it, `ovr_AssetFile_GetList` forwards to Meta's loader. `frame.langpacks` (opt-in, `native/langpack`) serves `<tag>.lang` files from the game's data; `elf.hide_exports` marks the loader's exports STB_LOCAL (bionic and glibc only match GLOBAL/WEAK; verified for glibc, bionic's `is_symbol_global_and_defined` is from memory). `libfp_langpack.so` is built here (`python native/build.py --only langpack`) and committed. Owner-verified 2026-10-04: Deadpool VR with only `en.lang` and the patch on plays English dialogue and runs normally (headless launch tests show 2-6 fps while it loads: not a regression sign). A dispatcher answer that arrives after we answered the timed-out GetList is dropped (one answer per request); games already in a library get `lang_packs` filled after an app update (`library._refresh_data_fields`). The library logs to logcat under the tag `fp_langpack` (dirs looked in, packs found, every language-pack call), so it shows up in the game's `launch.log`; an `ovr_AssetFile_GetList` the dispatcher leaves unanswered for 1.5 s is answered with our packs alone. Deadpool VR (Unreal) accepts a pack only when its `Metadata` equals the game's own version string (`ULanguagePacksSubsystem` compares it with `%s.%s.%s.%s.%s` built from the build info, e.g. `1.0.40.356975.Quest` = versionName; found by disassembling `libUE4.so`): the patch writes the APK's versionName into the library (`@FPMETA@` slot, `with_metadata`), `FRAMEPORT_LANGPACK_META` overrides it. Deadpool VR (2026-10-04, headset): German became selectable with that Metadata, but dialogue stayed silent (even English once reported as a pack) while the path was spelled `/sdcard/Android/obb/<pkg>/x.lang`; with the `/storage/emulated/0/Android/obb/<pkg>/x.lang` spelling (Unreal's own, now listed first in `scan_dirs`) German dialogue plays. `FRAMEPORT_LANGPACK_SKIP=<tags>` or a file `fp_langpack_skip` in the obb folder leaves packs out of the list (experiments).
`games/<pkg>/target/shaders/`. Triage `gpu-hang` suggests both dumps; `triage.graphics_api` (FrameBridge's
xrCreateSwapchain formats: <0x1000 Vulkan, else GL) keeps only the session's API's (`API_ONLY`). Host-tested only.
Agent v74: a reporter's hang came ~10 s after the last new module, so the culprit wasn't among the newest written →
with an index naming modules, `shader_dumps` sends every module of the index's **newest session** (after the last
`# start`), deduplicated, last used first, each ≤4 MB, ≤30 MB in all (`session` = how many it names) + that session's
index lines; no index (fp_spirv) = the old newest-by-mtime 4 MB. One JSON line (~40 MB base64) over the SSH channel
is read whole by `Frame.agent` (fine at that size); `_Writer.fit` drops the least recently used modules last, after
cutting logs, to stay under the 24 MB zip limit.
**Unreal OBB check (GitHub #159, 2026-10-10):** Epic's DownloaderActivity checks OBB name+size (OBBData), then with `bVerifyOBBOnStartUp=true` CRCs the whole OBB; its screens are invisible in Lepton (stuck at `Displayed …/.DownloaderActivity`, triage `unreal-obb-check-stuck`) → `frame.unreal_skip_obb_check` (analysis `unreal_verify_obb`, ANALYSIS_VERSION 11) flips the manifest boolean (`axml.set_meta_data_bool`); skips only the CRC pass. Host-tested only.
communication-device methods from `com.vivox.sdk.AudioChangeListener` with no SDK check → NoSuchMethodError on Lepton's
Android 11. `frame.vivox_audio_route` (analysis `vivox_api31`, ANALYSIS_VERSION 4) makes every such method return at
once (`Dex.return_early`: return-void / `const/4 v0,0; return v0`; nopping the invoke would leave a move-result the
verifier rejects). Older Vivox (Eleven Table Tennis, BattleSisters) lacks that code and isn't matched. Verified
headless: Vivox initialises, 150 s at ~65-70 fps.
**Steam Input gamepad for 2D apps (GitHub #162, agent v72, 2026-10-10):** Lepton's Android only has the Wayland seat's `wayland_touch/keyboard/pointer`. Steam makes its virtual pad (uinput, `/devices/virtual/input`, 28de:11ff, "Microsoft X-Box 360 pad N", ACL for steamos) only while the Frame's controllers are on (controller.txt "Steam Controller reserving XInput slot 0"; gone when they sleep), also with no game running; steamos-manager's 28de:0000 keys device isn't a pad (no BTN_SOUTH). Lepton's container root (system_server too) = steamos (`keep-id:uid=0`), so a bind-mounted `/dev/input/eventN` opens. Opt-in `device.steam_gamepad` (vr_kind none; suggested for `android.hardware.gamepad`/`LEANBACK_LAUNCHER`, analysis `gamepad`, ANALYSIS_VERSION 9): deployment.json `steam_gamepad` → launcher `GAMEPAD_LINE` (after the codec line: exports FRAMEPORT_GAMEPAD + LEPTON_ENV_SDL_GAMECONTROLLER_ALLOW_STEAM_VIRTUAL_GAMEPAD, puts `agent/bin` first on PATH) → `PODMAN_WRAPPER` (written by ensure_host_fixes; non-`run` calls go straight on; `run` imports the agent's `podman_run_args`; hands on to the next Podman after its own PATH entry with itself removed from PATH, so it chains to the codec wrapper either way round) adds the pads + `Vendor_28de_Product_<pid>.kl` (Xbox 360 layout). Verified headless with a uinput stand-in pad (Stremio's container: EventHub `classes=0x80000141`, our key layout, KeyEvent BUTTON_A dispatched); with Steam's real pad and a game: not yet. Pads made after the start aren't seen until the next one.
+ computed `slow-frames` (pacing windows vs the nearest refresh rate) and `focus-dips` (FrameBridge always logs
`focus: lost` / `focus: back after N ms`, session_fixes.c)) → library `last_session` / `last_session_checked` → game
page "Last session" callout (Try this fix / Rebuild with this fix / Yes-No question / Report / Dismiss). Suggestions may
be values (`adapter.scale=0.85`, `triage.split_suggestion`); adapter-only fixes are pushed live (`apply_suggestions_live`
→ agent set_settings, like the Game settings dialog). CLI `frameport session <pkg> [--apply]`. PC VR (Proton) launchers
log no session end, so they aren't triaged yet. pac_hints stays triage-only: a survey of all 68 dump APKs found unpaired
PAC hints in 21 libraries of 18 games (OpenSSL's 38/40 in most UE4 libUE4.so and libEOSSDK.so, UE5 libUnreal.so ~400
vs +2-3, libass, libopencv, …), most of them games that work, so default-on would rewrite many working builds.
**Start activity / QuestCraft / ITR2 pop-in:** `frame.start_activity` (analysis `extra.vr_activity`, `axml.set_start_activity`; OVRPort gives every MAIN activity LAUNCHER, so take the VR activity from the original APK); Unreal reads user config from **internal** storage; Lepton passes `LEPTON_ENV_<NAME>` to the app as `<NAME>` (QuestCraft `LIBGL_NOERROR`); vkshim `vk_query_slots` left off. → docs/DEVICE_NOTES.md#start-activity--questcraft--itr2-pop-in
**Vulkan validation / ITR2 solved:** bundle Khronos' `libVkLayer_khronos_validation.so` into a test APK + vkshim `vk_validation=1` (logcat tag VALIDATION); `vk_spec_fixes=1` drops ITR2's invalid depth resolve; VALVE_rpo removed its fog (catalog `lepton_env: VK_INSTANCE_LAYERS`). Agent `not_started` waits 30 s for "Boot complete!". → docs/DEVICE_NOTES.md#vulkan-validation--itr2-solved
**GitHub #38/#39:** SteamVR rejects image rects past their swapchain (-25) → FrameBridge `rect_clamp` (default on), triage `swapchain-rect-invalid`; The Room VR MSAA crash in libgallium. → docs/DEVICE_NOTES.md#github-3839-powerwash-simulator-the-room-vr
**Headset round 2026-10-05:** FrameBridge `pose_consistency` (I Am Cat judder), xrshim `haptic_fix` (Lucky's Tale), **`focus_hold` on by default with 5 s** (wear-sensor dips, `logs/eyetracking.txt`), `unity_no_overlay_copy` (The Room VR), ovrpshim frame wait for Unity 2019 (`UnityOculusCheck.legacy_loop`), `frame.ovr_trace` (opt-in, `native/ovrtrace`, logcat `fp_ovrtrace`). → docs/DEVICE_NOTES.md#headset-round-2026-10-05-evening
**Unity built-in VR input:** probe builds `FRAMEPORT_INPUT_PROBE=1`; ovrpshim adds a `GetMouseButtonDown` icall click (Accounting+); libunity 2019 only polls Touch when the device model starts with "Oculus" → `unity_oculus_check` revision 4 `oculus_model_checks` (BattleSisters); `haptic_fix` suggested for every game with libOVRPlugin.so. → docs/DEVICE_NOTES.md#unity-built-in-vr-input-accounting-battlesisters
**Vader Immortal (GitHub #49):** stuck on its loading card and leaked GPU mappings (solved below: `gl_error_clear`); diagnostics FrameBridge `layer_debug`, `strip_color_bias`, `frame_balance`, `snapshot=N` (`snapshot_gl.c`: saves the submitted left-eye image as `files/fb_snap_*.ppm`). → docs/DEVICE_NOTES.md#vader-immortal-headless-investigation
**SteamVR overlay apps:** host OpenVR overlays composite over Lepton games; detection `analysis/vroverlay.py`, patch `pcvr.vr_overlay`, Linux fields `vr_overlay`/`vr_overlay_autostart`, agent `register_vr_overlay`/`unregister_vr_overlay`/`launch_vr_overlay`; SteamVR on the Frame reads only `binary_path_linux_arm`; FramePort's own autostart (`ensure_overlay_service`, `frameport-vr-overlays.service`). See also docs/FRAME_RUNTIME.md "Overlay apps". → docs/DEVICE_NOTES.md#steamvr-overlay-apps
**Vader's leak solved / AC Nexus flips:** stale GL errors broke SteamVR's GL interop → adapter `gl_error_clear` (GLES, catalog for Vader ep1-3); read `xrclient_<pkg>.txt` in Steam's logs for runtime errors; the runtime caps swapchains per session (~15) → flip emulation in place; adapter `flip_dump`. → docs/DEVICE_NOTES.md#vaders-leak-solved--ac-nexus-flips
**Unreal's self-restart:** UE 4.21+ restarts itself after the first shader precompile and Lepton ends the container → launch.sh RESTART_BLOCK starts Lepton once more (`upgrade_launchers`; `FRAMEPORT_NO_RESTART=1` off). → docs/DEVICE_NOTES.md#unreals-self-restart
**xrWaitFrame runs ahead:** the runtime sometimes returns a display time <1 refresh after the last submit and rejects the second submission (`VRCompositorError_AlreadySubmitted`) → the VrApi bridge re-waits (`pacing 2s:` counters). → docs/DEVICE_NOTES.md#xrwaitframe-runs-ahead-journey-of-the-gods
**Double launch:** launch.sh takes `flock` on `<base>/.launch.lock` (fd 9); a second launch exits 0 and logs to `<base>/launch-dup.log` (`upgrade_launchers` adds it). → docs/DEVICE_NOTES.md#double-launch
**Issue triage round 2026-10-06:** FrameBridge turns haptic amplitude 0 into xrStopHapticFeedback, per-game `haptic_scale`; Lambda1VR → `frame.tbxr_vendor`; Jurassic World → `frame.vrapi_stub`; Metro Awakening / Pinball FX → `hide_space_warp`; `frame.ovr_trace` can't trace Unity games; the VrApi bridge's 30 s head-pose deadline ends headless VR mode. → docs/DEVICE_NOTES.md#issue-triage-round-2026-10-06
**Lepton storage:** each app's /sdcard has `Movies`/`Download`/`Documents` symlinked to the Frame's `~/Videos`/`~/Downloads`/`~/Documents` (agent `storage_targets`); the media index never works; Lepton grants all runtime permissions. → docs/DEVICE_NOTES.md#lepton-storage
**SteamVR per-app settings:** `native/vrsettings` = `fp_vrsettings.exe` sets `steam.app.<appid>` `preferredRefreshRate` / `motionSmoothingOverride` live; `pcvr.steamvr_tuning` (default on, PC only). → docs/DEVICE_NOTES.md#steamvr-per-app-settings
**Language packs:** `frame.langpacks` (opt-in, `native/langpack`, `elf.hide_exports`, logcat tag `fp_langpack`) serves `<tag>.lang` files; Unreal needs the pack's Metadata = the game's version (`with_metadata`, `FRAMEPORT_LANGPACK_META`) and the `/storage/emulated/0/...` path spelling; `FRAMEPORT_LANGPACK_SKIP`. → docs/DEVICE_NOTES.md#language-packs
**Cube swapchains:** the runtime refuses `faceCount=6` → FrameBridge `cube_standin` (default on, GLES only, `native/adapter/cube_standin.c`). → docs/DEVICE_NOTES.md#cube-swapchains
**Hardware video decoding:** `native/hevc` OMX plugin (`OMX.frameport.{avc,hevc,vp9}.decoder`), installed once per Frame (`ensure_video_codec`, agent `video_codec_status`/`install_video_codec`/`video_codec_switch`); **bump `revision` in native/hevc/build.py with every artifact change**; per game `frame.hw_video_decode` (analysis `media_codec`), Settings `video.hw_decode`, `FRAMEPORT_NO_HW_VIDEO=1`; Batman migration `batman_video_patches` + `surface_native`. → docs/DEVICE_NOTES.md#hardware-video-decoding
**Issue round 2026-10-12:** Lepton breaks on unquoted paths with spaces → launchers give Lepton a `~/.local/share/frameport/lepton-paths/<pkg>` link (`app_dir_lines`/`set_app_dir`/`launcher_base`); `frame.eos_keychain_loop`, `frame.unity_tls_key_pool` (`libfp_tkeys.so`, `elf.rename_imports`), `frame.vermillion_scene_canvas`; `tools/cpp2il.py` falls back to Cpp2IL's dev build for metadata v107; Linux `desktop_icon`; `scripts/upload_bench.py`. → docs/DEVICE_NOTES.md#issue-round-2026-10-12
**OpenSSH uploads (#324/#242):** `native_upload.quote` escapes only backslash and `"`, Win32 local paths go as `C:/…`; `Frame.auth` records the login that worked (app_key / user_key from `ssh.extra_keys`, `frame ssh-keys`, agent, password); strict IdentitiesOnly first, relaxed retry. → docs/DEVICE_NOTES.md#openssh-uploads
**Meta user id (#182):** OVRPort's platform loader makes up a new user id every start → `frame.ovr_stable_user` (default on) returns a stable per-game, per-user id. → docs/DEVICE_NOTES.md#meta-user-id
