fix: fall back to a devkit entry when Steam drops the library shortcut

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.

 title: 'Star Wars: Tales from the Galaxy''s Edge'
-status: unknown
-notes: Not working yet - after the intro logos and a loading animation the picture goes black (GitHub issue 61).
-  Gets the controller fixes found for Vader Immortal (same studio) to test.
+status: works
+notes: >-
+  Headset tested for GitHub issue 61: full view, loading into gameplay, both eyes, controller input and sound
+  work with the splash bypass and multiview depth-size fix. Keep the main OBB and all three content/sound-bank PAKs.
 details: Unreal Engine 4 (GLES) by ILMxLAB, like Vader Immortal, but a different engine build - it has none of Vader's
  Quest-only branches (no GetQuestShaderPrecompilePercent or RPOC key map; it precompiles shaders through Unreal's
  own pipeline cache), so frame.unreal_quest_precompile/_keymap don't apply. Its seasons and Wwise banks are Meta
  platform asset files (frame.asset_files). Vader's OVRPlugin findings apply to it as well - poses asked for at
  OVRPlugin's own clock (pose_time_fix) and thumbs from near-touch, which the Frame never reports (frame.unreal_thumb_touch).
-  Ruled out for the black picture so far (see the diagnostics in issue 61) - asset-file paks, Valve's foveation,
-  GL errors; the game's own eye image reads back black.
+  Map travel stalls with the game thread waiting in FlushRenderingCommands and the render thread waiting in
+  FSplash::RenderFrame_RenderThread / ovrp_WaitToBeginFrame. frame.unreal_splash_bypass lets loading finish.
+  SideQuest backups with sibling apk/ and obb/ folders must include all three PAKs; old scans omitted them and
+  lost sound. The scanner and library refresh recover that layout. Eye clipping came from cached Android window
+  dimensions for the depth attachment (1920x1016 versus the 1728x1728 eye color texture).
+  frame.unreal_multiview_depth refreshes both cached dimensions from the current eye render size; multiview and
+  multisampling remain enabled. The two engine fixes check exported symbols, function sizes and instruction bytes
+  before changing one instruction each; unrecognized engine builds are left unchanged.

+## Where are a game's settings in FramePort?
+
+Every game has three places; the answers below refer to them.
+
+- **Game settings:** right-click the game in the **Library** → **Game settings…**. Sharpness, refresh rate,
+  controllers, menus and more, in plain words. Changes apply the next time the game starts.
+- **Patches:** click the game in the **Library** to open its page, then **Customize** (in the **Patches** section).
+  Turn a patch on or off, then click **Update on Frame** at the top of the page.
+- **The game's menu:** the **…** button at the top of its page (or right-click in the Library → **More actions…**).
+  It has **Reset to suggested recipe…** and **Report a problem…**, among others.
+
+The sidebar has two tabs for troubleshooting: **Monitor** (the running game's frame rate, CPU and graphics) and
+**Files** (each installed game's storage on the Frame, under **Game storage**).
+
+## A game doesn't work right. Where do I start?
+
+1. **Update FramePort** (it offers updates itself; Settings → Updates), then open the game's page: if it shows
+   **Update on Frame**, click it. Recipes and patches improve often.
+2. **Read the game's page.** The last launch test and your last play session (**Last session**) leave their result
+   there, often with a suggested patch or setting and a button that applies it. Try that first.
+3. **Changed patches yourself?** The game's menu → **Reset to suggested recipe…** brings back the tested ones.
+4. **Find your symptom below.** Each answer says how to tell what's wrong and what to do.
+5. **Still stuck?** Report it (last answer on this page).
+
+## The game doesn't start, or stops right away
+
+How to tell: the game's page shows the last launch test's result (**Last launch test:** …) with an explanation, and
+Steam returns to **Play** or **Resume** within seconds.
+
+- **"Game data (.obb) is missing"** on the game's page: FramePort didn't find the game's data files, so they never
+  reached the Frame.
+  1. Find the game's `.obb` files (named like `main.<version>.<package>.obb`).
+  2. Put them in a folder named exactly the package name (shown in the file names) next to the game's APK, as in the
+     first answer on this page.
+  3. Library → **Add games** → **Scan a folder…** and pick the game's folder.
+  4. Open the game's page and click **Update on Frame**.
+- **"Lepton didn't start the game this time"**, or it failed only on the first start after an install: click **Play**
+  again.
+- **"This game is 32-bit only"**: the Frame can't run 32-bit apps, and no patch changes that. Look for a PC VR version
+  of the game.
+- **"The game quit itself right after starting"**: open the game's page and click **Update on Frame** so the suggested
+  patches apply (many games check for a Quest at start, and a patch removes that).
+- **Nothing like that, or it still fails:** report it.
+
+## It hangs on a logo, a black screen or a loading screen
+
+How to tell what it's doing: leave it running and open **Monitor** in FramePort's sidebar.
+
+- **CPU or graphics busy:** it's still working, often preparing its shaders on the first start. Wait up to 10 minutes
+  once; the next start is quicker.
+- **CPU and graphics near zero:** it's stuck waiting for something. While it still hangs, open the game's menu →
+  **Report a problem…** and save the diagnostics: that zip shows what each of the game's threads waits for (FramePort
+  1.0.1 and newer), which a zip saved after quitting can't. Attach it to the report.
+- **The game starts with a video** and hangs at its logo: game page → **Customize** → turn off **Hardware video
+  decoding** → **Update on Frame**, and try again.
+
+## The picture is wrong
+
+Most picture problems have a setting or a patch. Change one thing at a time, then start the game again (patches also
+need **Update on Frame**).
+
+| You see | Try |
+|---|---|
+| Something shows in one eye only, or one eye is gray (Unity games) | Game page → **Customize** → [Unity: render each eye separately](PATCHES.md#frame-unity_multipass) |
+| Left and right look swapped (depth feels wrong) | **Game settings…** → **Swap eyes** |
+| Textures flicker, objects pop in and out | **Game settings…** → **Turn off space warp** |
+| One eye shimmers while menus look steady | Game page → **Customize** → **Eye-tracked foveation (Valve)**: **Fixed**, else **Off** |
+| Menus or screens upside down | **Game settings…** → **Fix upside-down menus** |
+| Curved menus or video screens missing | **Game settings…** → **Show curved menus and screens** |
+| Blurry | **Game settings…** → raise **Sharpness** (costs frame rate) |
+
+The [patch reference](PATCHES.md) lists every patch with what it does. If nothing helps, report it with a short
+description of what you see.
+
+## It stutters or runs slowly
+
+How to tell: open **Monitor** in the sidebar while you play. Smooth play needs the game's frame rate at the refresh
+rate (for example 72 or 90 fps).
+
+- **Below the refresh rate:** right-click the game → **Game settings…** → lower **Sharpness** (for example to 0.8×) or
+  pick a lower **Refresh rate**. After a session, the game's page may suggest a value.
+- **At the refresh rate but it still judders:** report it; that points to timing, not speed.
+
+## The game pauses or recenters by itself
+
+The Frame briefly tells games they lost focus, for example when the headset's sensor thinks you took it off.
+Right-click the game → **Game settings…**: keep **Don't pause on short interruptions** on and raise **Ignore focus
+dips up to** (for example to 2.5 s).
+
+## Controllers don't work in a game
+
+Right-click the game → **Game settings…**:
+
+- **No controllers, or only hands:** turn on **Use controllers**.
+- **Buttons work but you can't aim at menus:** adjust **Pointer angle**.
+- **Vibration too strong:** lower **Vibration strength**.
+
+## The Frame turns off or gets hot during a game
+
+How to tell: if it only happens on battery and never while plugged in, it's power, not FramePort. Heavy games can
+draw more than the battery delivers, especially at lower charge, and the Frame then turns off without an error.
+
+- Play plugged in, or right-click the game → **Game settings…** → lower **Sharpness** to reduce the load.
+- It also turns off while plugged in: report it. The diagnostics include the log of the boot that ended.
+
+## My progress isn't saved
+
+1. Quit through the game's own menu, not Steam's **Exit game**. Exit game closes the game at once, and some games only
+   save when they exit normally.
+2. Check whether it saves at all: **Files** in the sidebar → under **Game storage**, the game → look at the files'
+   dates. Play, save in the game, quit from its menu and look again.
+3. Nothing changes: report it.
+
+Saves stay on the Frame when you update or reinstall a game.
+
+## A game with mods crashes
+
+How to tell: play once without mods and custom content. If it then works, a mod is the cause; the diagnostics zip
+usually names the mod's library in the crash. Report it to the mod's author, and check for a mod version that matches
+your game version.
+
+## The game needs files I supply (ports, emulators, mods)
+
+How to tell where they go: the game says it on screen or in its instructions, and its log names the path (in the
+diagnostics zip, `launch.log`). It's usually `Android/data/<package>/files`.
+
+1. Unpack or extract the files on your PC first: these apps read folders, not disc images (`.iso`) or archives.
+2. **Files** in the sidebar → under **Game storage**, the game → open that folder → **Upload folder…** (or
+   **Upload files…**). The game's menu → **Add videos and files** opens the same place.
+
+In-game "choose a file" buttons don't work on the Frame, which has no file picker.
+
+## How do I report a problem well?
+
+1. Reproduce it once, then right away open the game's menu (**…** on its page) → **Report a problem…**. For a hang,
+   do it while the game still hangs.
+2. Say what you saw in the headset and what you already tried.
+3. **Collect and open GitHub** saves a diagnostics zip and opens a prefilled game report; attach the zip to it. The
+   zip holds logs, not your game files, and personal details are removed.

+## Lua native pointer compatibility
+
+Frame's Android processes can map libraries above the lowest 2^47 bytes of address space. The verified xLua API 105
+engine in BattleTalent 4.7 rejects those otherwise valid pointers in `lua_pushlightuserdata`. This was isolated using
+the unchanged library from the source APK: a real allocation at `0x10000000` round-trips, but its own native `xlua_tag`
+pointer above 47 bits raises `bad light userdata pointer` and exits. With `frame.luajit_pointers`, both round-trip
+exactly. No game scripts or account checks are changed. This validates an address-layout compatibility requirement;
+the APK was not run on an actual Quest during this investigation.
+
+The patch is restricted to SHA-256 `6d5860e4a4f1cc2b05c600c63297ed467369739666edca79413fff4374ff2684`.
+It redirects only the Lua engine's public API to a pinned full-pointer LuaJIT, keeping the original xLua bindings,
+LuaSocket and game helpers. The patched build survives a 60 s headless launch and creates OpenXR swapchains.
+Early frame-rectangle errors and backend login errors remain in the capture; this does not verify rendering or play.
+An arbitrary `lj_err_throw` followed by Unity destructor failures does not prove this pointer issue: first capture the
+Lua error text. `Unknown Platform` also appears after this crash is fixed, so it was not the fatal cause here.

+  A temporary `FDM_DEBUG=enable,debug` launch created the Unity/Manta Vulkan instance and device,

+## Shared foveation controls (tested 2026-10-12)
+
+Under a Quest game's Advanced patches, choose **Foveated rendering → Eye-tracked**, then **Update on Frame**.
+The full-resolution area selector defaults to **Default (30% radius)**: no radius override, preserving the
+runtime profile used in the headset experiments. Larger radii retain more detail and save less shading work.
+Custom radii set `FOVE_INNER`; `FOVE_OUTER` is twice that value, matching the runtime's profile proportions.
+The inspected runtime's built-in inner/outer pairs are 0.30/0.60, 0.25/0.50 and 0.20/0.40.
+The shared-texture injection path selects profile 1: 0.30 inner radius and 0.60 outer radius.
+
+`device.foveation` enables Valve's shared Vulkan injection and suppresses competing native foveation through
+`foveation_fix=1`. Recipes and shared catalog entries preserve mode, radius and test selection. This remains
+experimental: complete images were confirmed in RE4, Batman, Deadpool, The Climb 2 and Asgard's Wrath 2,
+not all Quest games or renderers. RE4 and Batman checks include title/calibration scenes; these are not
+equivalent to extended gameplay coverage. Asgard gameplay was visually confirmed, without an on/off benchmark.
+Batman additionally receives the verified ordinary shared-allocation patch, guarded by the full original
+OVRPlugin hash; unknown Batman versions fail explicitly rather than receiving unchecked binary offsets.
+
+The Climb 2 uses a private `libvrapi_foveation.so` bridge, installed only into that game's APK after the
+standard bridge patch. It retains images during held-focus visibility dips, separates mono overlay output
+storage from stereo density-map storage, and rate-limits its view-cache writes. Its process-local Valve layer
+correction supplies both eye offsets and avoids the invalid subpass mask-table reads seen during Alps loading;
+`yflip` corrects vertical gaze direction. The renderer SHA-256 and 1.0 resolution scale are checked before
+installation. The runtime correction additionally checks the exact Valve library SHA-256 and all four original
+instructions before touching executable memory; unsupported libraries request injection be disabled and log
+the reason. No system library is changed. A SteamOS update requires revalidation of this compatibility path.
+Both-eye gaze following was confirmed in Climb's darkening diagnostic, but long-session stability remains
+experimental. Off rebuilds from the source APK and removes this private support, including its visibility fix.
+
+**Darken lower-resolution regions (test)** adds an optional Vulkan shader diagnostic. It dims RGB where the
+actual `FragSizeEXT` footprint exceeds one pixel; alpha is unchanged. Deadpool's shaded regions were confirmed
+to follow gaze in the headset. Unsupported shader output interfaces are skipped, and multiple passes may
+compound darkening, so this is a diagnostic rather than a precise composited mask. Do not benchmark with it on.
+Uncheck it and update from the original source APK to remove the diagnostic library, except in Climb where
+the same library also carries the compatibility correction. Darkening stays dormant without its launcher opt-in.
+
+High-resolution Deadpool samples crossed from about 45 to 90 FPS with injection enabled, but temperatures and
+power rose as it rendered twice as many frames. Foveation does not guarantee lower temperature at uncapped FPS.
+The new configurable radii have configuration/build coverage; each radius has not been separately play-tested.

 # Patches

-Every patch and game setting FramePort knows: 155 entries in 5 groups.

+Every patch and game setting FramePort knows: 166 entries in 5 groups. A game's recipe is its chosen patches and settings; tested games get theirs from the catalog ([GAMES.md](GAMES.md)), and other games get the patches FramePort suggests from its analysis. You change them on the game page under Customize.

 Each entry says what the patch does, whether it changes the APK or only the install, when FramePort suggests it, its options, the catalog games whose recipe names it and the launch-test signatures that suggest it. Patches that are on by default are on for every game, so the catalog rarely names them.

-> Valve's foveation layer (VALVE_fdm_injection) lowers the image density away from where you look, following each eye's gaze. In some games one eye then shimmers or jitters while menus look fine (the right eye's gaze filter restarts often). "Fixed" keeps the foveation but stops it following the gaze (FDM_DEBUG=disable_offsets); "Off" loads none of Valve's Vulkan layers (VK_INSTANCE_LAYERS=""; costs GPU time in heavy games).
+> Reduces shading away from the full-resolution area, following each eye's gaze. Default area size keeps the runtime's current profile unchanged. Custom radius is a fraction of the shorter eye-image dimension; the transition ends at twice that radius. Larger areas retain more detail but save less GPU work. Fixed stops the area following your eyes. The optional test darkens actual coarse-shaded fragments; rebuild/reinstall to toggle it. Tested on RE4, Deadpool and Asgard's Wrath 2. The Climb 2 gets a version-guarded private bridge at 1.0 scale; Batman gets its hash-verified allocation fix (unsupported OVRPlugin versions are refused). Other games may need additional fixes; turn this off if artifacts appear.

Controlled tests with the unchanged library pass a real low-address allocation and fail its own high-address static pointer | `frame.luajit_pointers` automatically selects a full-pointer Lua engine only for the verified library SHA-256, retaining xLua bindings and custom helpers. The scoped patch reaches OpenXR startup for 60 s headless; rendering and gameplay remain unverified.

GL queries and single-sampled framebuffer fixes remain active; other games retain the draw hooks. A/B eye captures on SteamOS 0.4.5: old shim normal, current shim spikes, current shim with private draw symbols normal at ~72 fps. Worn-headset gameplay still needs confirmation |

A missing / wrong-size OBB starts Google Play's downloader (or a "No Google Play Store Key" dialog) and also waits | `frame.unreal_skip_obb_check` (suggested by analysis `unreal_verify_obb`): sets that meta-data to false (one boolean in the manifest, `axml.set_meta_data_bool`), which skips only the CRC pass.

 ## Stable composition

+Adapter-owned video outputs explicitly request a static

+The profile applies only to those outputs; application eye swapchains retain

+fix pixelation and added a private full-size image copy. The full-rate runtime
+profile fixed pixelation in the headset; the restored raster path was confirmed sharp and improved in-game presentation
+from roughly 40–44 to 65–71 FPS in the sampled cutscene. It still needs further
+performance work. Fully opaque video pixels skip the invisible scene texture
+sample and colour transform; partially transparent pixels retain the full blend. The next live cutscene run reported about 84 FPS across its first five post-startup samples, versus about 69 in the preceding run, with decoding steady at 60 FPS. These separate samples do not control for head motion or temperature; smooth playback is not yet fully established. The video surface patch revision marks affected
+recipes for rebuilding without forcing unrelated game updates.
+
+Once native video composition is active, the compositor can sample an sRGB view
+of the worker's shared hardware buffer directly. The renderer retains the slot
+across repeated frames; replacement queues a foreign-queue ownership handoff
+behind earlier compositor reads, and only its signalled fence makes the old slot
+reusable by the worker. Missing compatible views and initial/fallback presentation
+retain the copy path. The full-rate video profile and output resolution are
+unchanged. Deployment/performance validation is initially limited to Batman.
+The headset playback check confirmed good performance, and the live log confirms
+`direct shared-buffer sampling; cache copy skipped`. During active video,
+recorded application pacing was approximately 105–107 FPS, with decoding around
+60 FPS and visible-view GPU waits around 4.0–4.8 ms, versus roughly 6 ms in the

+benchmark. The 8192x4096 decoded input and 2560x2560-per-eye output are retained;

+## Production OpenSSH follow-up
+
+OpenSSH is now the preferred installer backend for files >=8 MiB. The new default is three workers (range 1–8),
+with saved preferences preserved. Fresh files use `put`; existing partial files use `reput`. Each worker keeps
+one SFTP batch session. Progress is polled through a separate bounded SFTP channel. Native failures resume via
+Paramiko; cancellation stops the owned SFTP/SSH process trees and does not trigger fallback.
+
+Windows matched production comparison: eight 64 MiB files, 512 MiB total, three shuffled repetitions per backend,
+three workers, same home Wi-Fi/internal storage. OpenSSH median **15.51 MB/s**, Paramiko median **11.08 MB/s**
+(about 40% faster). All six checksums passed. OpenSSH trials ranged 9.5–16.8 MB/s, so link variability still
+matters; it was slower than Paramiko in one pass. Native credential/progress setup took 0.12–0.13 seconds.
+
+The separate Windows 128 MiB production test also passed every checksum. Native cancellation left a partial file
+of 74,752,000 bytes; resuming with OpenSSH produced the expected SHA-256. The log confirmed no fallback for the
+resumed production upload. Reports:
+`/mnt/c/Users/Austin/AppData/Local/Temp/frameport-upload-native-production-comparison-windows.json` and
+`/mnt/c/Users/Austin/AppData/Local/Temp/frameport-upload-native-production-windows.json`.
+
+The earlier sections below preserve measurements made before the production backend switch.
+
+The WSL production validation (128 MiB, three workers, three repetitions) measured 14.1 / 19.1 / 15.0 MB/s,
+with every checksum passing and native backend logs recorded. Production cancellation left a 72,330,240-byte
+partial file; OpenSSH resumed it in 4.23 seconds with the expected SHA-256 and no Paramiko fallback. Report:
+`/tmp/frameport-upload-native-production-wsl.json`.
+
+## Measurements (2026-10-14)
+
+Both runs used the same paired Frame, the home-router connection and internal ext4 storage under the paired user's
+home. Each large-file trial sent the same 128 MiB random payload; each small-file trial sent 512 files of 64 KiB
+(32 MiB total). Methods were shuffled for each of three repetitions. Windows and WSL runs were sequential, not
+concurrent. Every completed transfer passed SHA-256 verification. Rates below include connection/setup and transfer
+completion, but exclude checksum verification and cleanup; MB/s uses decimal bytes.
+
+| Method | WSL2 median MB/s | Windows 11 native median MB/s |
+|---|---:|---:|
+| FramePort pipelined SFTP | 10.4 | 6.1 |
+| Paramiko SFTP, 64 MiB window | 17.1 | 4.5 |
+| OpenSSH SFTP | 16.8 | 15.4 |
+| OpenSSH SCP (default protocol) | 11.1 | 10.1 |
+| OpenSSH `ssh` + streamed file | 9.9 | 8.1 |
+| FramePort tar stream | 14.9 | 6.8 |
+| OpenSSH tar stream | 15.0 | 7.2 |
+
+The network varied considerably: WSL's application trials ranged from 9.6–12.8 MB/s, native SFTP from
+16.2–17.3 MB/s, and some other methods dropped below 5 MB/s. Windows application trials ranged from 5.6–6.4 MB/s;
+native SFTP ranged from 9.1–16.5 MB/s. These are useful end-to-end comparisons on this setup, not a measurement of
+the maximum throughput each transport can achieve. Window tuning did not help the Windows run.
+
+Cancellation/resume checks interrupted the application upload at 64 MiB, then independently resumed that partial
+file with the application and with OpenSSH SFTP `reput`. All four resumed files passed SHA-256 verification. This
+checks application cancellation and both resume paths; native SFTP cancellation itself remains unmeasured.
+
+The Frame's USB and hotspot interfaces were up, but neither direct endpoint was reachable from the PC. No removable
+storage was mounted. USB, hotspot and microSD performance remain **unmeasured** in this round. The Frame's router
+connection used 5 GHz / 80 MHz Wi-Fi, with roughly -56 dBm signal during a read-only probe. This does not reproduce
+the 6 GHz direct-hotspot setup in [discussion #242](https://github.com/spoopyghosty0/frameport/discussions/242), where
+the reporter measured about 114 MB/s with OpenSSH versus 23 MB/s with Paramiko.
+
+**Recommendation:** prototype an optional OpenSSH SFTP backend for large files, retaining `.part`/`reput`,
+cancellation, retries, strict paired-host verification and Paramiko fallback. Validate it on a fast direct link
+before making it the default. On this Windows run SFTP was about 2.5 times faster than the current application,
+and it beat SCP. The small-file tar measurements do not justify selecting a new tar transport yet. Production
+transport selection remains Paramiko pending that decision. The bounded parallel-file setting described below
+uses independent Paramiko connections.
+
+## Parallel-file uploads
+
+### Matched native OpenSSH comparison
+
+The later comparison tested both backends sequentially on Windows and WSL, with three shuffled repetitions of
+the same eight 16 MiB files per worker count. Native `sftp-files-N` balances files across N persistent OpenSSH
+SFTP batch processes. Setup and completion are included; checksum verification is excluded. All 60 transfers
+passed SHA-256 checks. This is benchmark code; the production uploader still uses Paramiko.
+
+| Workers | Windows Paramiko MB/s | Windows OpenSSH MB/s | WSL Paramiko MB/s | WSL OpenSSH MB/s |
+|---|---:|---:|---:|---:|
+| 1 | 6.22 | 14.96 | 6.17 | 14.64 |
+| 2 | 10.61 | 17.73 | 14.41 | 14.45 |
+| 3 | 8.90 | 18.89 | 13.65 | 17.75 |
+| 4 | 14.90 | 16.80 | 15.67 | 16.63 |
+| 8 | 13.50 | 20.16 | 17.03 | 16.82 |
+
+Three is a reasonable default candidate for a future OpenSSH backend: versus two it improved median throughput
+by 6.5% on Windows and 22.8% on WSL. Eight was faster on Windows but slower on WSL. The production Paramiko
+default remains two because three regressed by 16.1% on Windows and 5.3% on WSL in this matched comparison.
+Link variability remains substantial, and no fast hotspot/USB result is claimed.

+Settings → Installing → **Parallel uploads** accepts **1–8**, default **2**. It controls large files within one
+install; the FIFO still runs one install job at a time. A single APK is not split into chunks. Large files are
+scheduled largest first, with at most one authenticated SSH connection per active worker and never more workers
+than files. Small files still use tar batches after the large-file uploads. Choose 1 on a busy network; a higher
+count can consume all available bandwidth and is not automatically faster.
+
+The parallel comparison uses the same eight 16 MiB OBB-shaped files (128 MiB total) for every worker count, with
+three shuffled repetitions. The production uploader is used by `app-files-N`, including its aggregate progress,
+resume baselines, cancellation checks and connection cleanup. A failed or cancelled cohort stops queued work and
+closes only its worker transports; completed files and interrupted `.part` files remain resumable.

+| Workers | WSL2 production median MB/s | Windows 11 production median MB/s |
+|---|---:|---:|
+| 1 | 9.6 | 5.6 |
+| 2 (default) | 9.1 | 10.9 |
+| 3 | 6.5 | Not measured in the final production run |
+| 4 | 12.4 | 14.8 |
+| 8 | 11.2 | 17.3 |
+
+On Windows, the production uploader improved from 5.6 to 10.9 MB/s with 2 workers (**1.95 times faster**), and
+17.3 MB/s with 8 (**3.08 times faster**). All twelve Windows production transfers passed SHA-256 verification.
+The preceding Windows prototype also tested 3 workers (12.2 MB/s median), before aggregate progress/cancellation
+were integrated; that is not included as a production measurement in the table.
+
+WSL was noisy: four workers improved its median by about 29%, but 2 did not improve its median, and 3 was slower.
+There is no evidence that a particular worker count is universally fastest. The option is retained because it
+produced a repeatable benefit on Windows and higher counts improved the WSL median. Default 2 limits competing
+transfers while retaining a measured Windows benefit; users can measure higher counts or select 1 in their own
+environment. Production code, including cleanup and progress checks, was used for both final comparisons.
+
+```sh
+uv run python scripts/upload_bench.py --mib 128 --repeat 3 --methods app-files-1,app-files-2,app-files-3,app-files-4,app-files-8 --json parallel.json
+```
+
+`install.upload_threads` persists the setting. Malformed values use 2 and numeric values are clamped to 1–8.
+The serial setting reuses the existing control connection; parallel workers verify that the new transport reaches
+the same paired headset before sending any files.
+
+## Reproducing the measurements
+
+Run from the checkout using the Python environment for the platform being measured:
+
+```sh
+uv run python scripts/upload_bench.py --mib 512 --repeat 3 --check-resume --json uploads.json
+uv run python scripts/upload_bench.py --fast-link --probe
+uv run python scripts/upload_bench.py --fast-link --remote-dir /path/on/card --mib 512 --repeat 3 --json card.json
+```
+
+`--host` selects a specific paired endpoint; `--fast-link` uses the same authenticated direct-link discovery as an
+install. Inspect the reported endpoint and link before comparing methods. Join the Frame's hotspot or connect its
+USB cable before testing those paths; the benchmark does not change PC networking. Keep the headset awake and avoid
+other network traffic. A 512 MiB payload is preferred for follow-up tests on fast links; the available-link runs
+above used 128 MiB.
+
+The script creates a unique scratch directory on the selected filesystem, checks content outside the timed upload,
+and removes its own temporary remote files and temporary key copy. It never modifies the pairing key's ACL. Windows
+OpenSSH rejects an `OWNER RIGHTS` ACL entry; the temporary copy grants only the current user, without Python's
+Windows `chmod` behaviour that can introduce that entry. Native clients use the application's key and known-hosts
+file with strict host verification.
+
+JSON rows contain bytes, total seconds, separately measured setup seconds where available, payload and total rates,
+verification duration and checksums. SCP/SFTP's setup is included in total time because their command-line clients
+do not expose its completion separately. On POSIX, CPU includes the Python parent and child processes; on Windows,
+`os.times()` measures only the parent, so native subprocess CPU numbers must not be compared with Paramiko's CPU.
+An error is recorded rather than counted as a successful trial. `--methods` can restrict the run; `--small-files`
+controls the tar corpus. Cipher comparisons are available as `ssh-gcm` and `ssh-chacha`.
+
+## Incremental install behaviour
+
+`game_update.plan_update` is the shared, I/O-free Quest/Android classifier used by badges and installation. Recipe
+source, notes and catalog revision do not affect it. A newer tested catalog recipe remains a separate suggestion
+when the user customized their recipe.
+
+- Build records keep an APK recipe fingerprint, source hash/stat, selected native-asset identities, converter
+  identity and the existing validated APK hashes. Reusable local APKs are checksum-checked before installation.
+- Deployment records keep applied runtime configuration and its fingerprint, APK stat/hash, source version,
+  data manifest/digest and artwork hashes. Routine device samples carry only the digest, and updates fetch a
+  detailed manifest only when necessary. Live numeric settings writes update only the applied runtime configuration,
+  leaving APK build identity intact. Desired data manifests are cached locally for badges, without render-path I/O.
+- Runtime-only updates use agent v87 `configure`: no conversion, signing, APK transfer, artwork, Steam restart or
+  automatic launch test. They still require the installed APK identity and an available destination, and refuse
+  changes while the game is running. Defaults explicitly reset overrides embedded in an older APK. Generated
+  configuration files are restored or removed only when they still match FramePort's last write; user edits survive.
+- Build support dependencies remain conservative: controller models/native surfaces/haptic support, Zink-layer
+  selection, mixed foveation patches and revised adapter support can require a new APK. A recorded alternate
+  variant can be reused when switching variants.
+- Data-only updates transfer missing/different-size data using the resumable uploader. Recipe/APK updates skip
+  data synchronization when the source data manifest is unchanged, preserving Frame-side mods; explicit forced
+  reinstalls still check/repair data. Artwork-only
+  updates send changed slots; unchanged artwork avoids a Steam refresh. APK/data changes retain the configured
+  automatic launch test. Settings/artwork changes skip it.
+- APK-only updates preserve installed OBBs, including mods, and do not apply old staged OBBs or artwork from an
+  interrupted upload. Ordinary data comparison still uses sizes, matching existing behaviour; equal-size content
+  replacement is not detected automatically. Explicit rebuild/reinstall remains available (`install --force`).
+- Legacy build identities take the full path once because their original build inputs cannot be established
+  safely. Converted-copy cleanup and `build.keep_copies` remain in effect; a configuration/data update does not
+  require the deleted converted APK.
+
+Install results record `stage_seconds` in the library's install history. This includes planning, conversion,
+validation, transfer and finalization stages reached by that operation; the GUI's subsequent optional launch test
+is separate. Use these timings to distinguish build cost, network transfer and device/Steam work when reviewing a
+slow install. Configuration success is recorded after writing the configuration and completing its sync; a failed
+operation leaves the prior applied fingerprint so it remains retryable.

 | `platformcompat/` | `arm64-v8a/libovrplatformcompat.so` | Real `ovrMessageType_ToString` (same fork, `native/platform`). |
 | `langpack/` | `arm64-v8a/libfp_langpack.so` | Language packs for the Meta Platform SDK (patch `frame.langpacks`, opt-in). overport's platform loader is a dispatcher in front of Meta's own loader and answers `ovr_LanguagePack_GetCurrent/SetCurrent` with `return 0` (no reply ever). This library becomes the loader's first DT_NEEDED; the loader's own exports of the 31 functions it defines are made STB_LOCAL in `.dynsym` (`elf.hide_exports`, nothing moves), so symbol lookups reach the library first. It serves `<tag>.lang` files found in the game's OBB / app files (`$FRAMEPORT_LANGPACK_DIRS` overrides the search path) through `ovr_LanguagePack_*`, `ovr_AssetFile_GetList` (the loader's list + the packs) and `ovr_AssetFile_StatusById`; its own message queue is merged into `ovr_PopMessage`, and every handle that is not ours (an address-range check) goes to the loader's original function, whose address is read at run time from the loader's in-memory `.dynsym`. With patch `frame.asset_files` (marker byte `@FPASSETS@`, or env `FRAMEPORT_ASSET_FILES=1`) it also lists the data's `*.pak` content files as installed `default` asset files and answers `ovr_AssetFile_DownloadById` for them at once (a completed `DownloadUpdate`, then the result with the path). Host-tested against a stand-in loader (`tests/test_langpack.py`, plain `cc`, no NDK); the bionic/headset side is unverified. |
 | `glshim/` | `arm64-v8a/libglshim.so` | Mesa GLSL compatibility for GLAD engines (hooks eglGetProcAddress): comments out `#pragma` before `#extension`, enables `GL_EXT_shader_implicit_conversions`, hides GL_OVR_multiview (`gl_hide_multiview`, default 1) and logs failed shaders. `-DGLSHIM_TRACE` adds per-FBO draw/error tracing. |
 | `glmv/` | `arm64-v8a/libfpglmv.so` | Single-view draws of OVR_multiview programs (patch `frame.gl_multiview_fbo`, opt-in, GitHub #77). Mesa enforces OVR_multiview's rule that a draw's program declares as many views as the draw framebuffer has; engines that compile every shader with `num_views=2` and also draw into ordinary 2D framebuffers (Doom3Quest's HUD/PDA pool) lose those draws. The engine library gets it as first DT_NEEDED (direct `gl*` imports) and its `dlopen("libGLESv3.so")` string is rewritten to `libfpglmv.so` (same length; its `qgl*` dlsym table); linked `--no-as-needed` to libGLESv3 so dlsym on its handle finds everything it doesn't wrap. It records stage sources at glLinkProgram, caches the draw framebuffer's color-attachment view count per bind, and when a multiview program draws into a 0-view framebuffer it binds a lazily built twin (`glmv_rewrite.h`: num_views layout blanked, `gl_ViewID_OVR` -> `(0u)`; attribute locations + uniform block bindings copied, default-block uniforms copied before every such draw with a shadow to skip unchanged ones), draws, rebinds the original. Logcat tag `GLMV`; `gl_mv_debug=1`. The rewriter is host-tested on Doom3Quest's 19 shaders (`tests/test_gl_multiview_fbo.py`); untested on the device. |
+| `tlskeys/` | `arm64-v8a/libfp_tkeys.so` | Thread-key pool for Unity (patch `frame.unity_tls_key_pool`, opt-in, GitHub #198; approach and the first helper by Klownicle). Bionic allows 128 pthread keys per process; Unity 6 plus large native libraries (Firebase, Gecko) and the Frame's own libraries use them up (Wander: `cannot create thread specific key for __cxa_get_globals()`). libunity.so's four key imports are renamed to `fp_tkey_create/_delete/_get/_set` (`elf.rename_imports`, same `.dynstr` bytes, versions set global) and this library is added to its DT_NEEDED: keys without a destructor become slots (512, generation-tagged, `0x40000000 + slot`) in a per-thread table under one real key; keys with a destructor and all other libraries keep real keys. Lock-free get/set. Logs `fp_tkeys: pooling Unity's thread keys` once (tag FrameBridge). Host-tested (rename); not yet run on the device. |
 | `zinkfix/` | `arm64-v8a/libVkLayer_fp_shaderfix.so` | Shader-fix Vulkan layer `VK_LAYER_FP_shader_fix` for OpenGL ES games (patch `frame.zink_shader_fix`): sits between Zink (Mesa's GL on Vulkan) and the driver and inserts the words of `zink_shader_fix` (same format as the Vulkan shim's `vk_shader_fix`: size + SHA-256 match) into SPIR-V modules; `zink_shader_dump=1` writes every distinct module to `files/fp_spirv/`. The engine library loads it first (DT_NEEDED); its constructor puts the layer in front of Android's GraphicsEnv debug layer list (private Android 11 `getDebugLayers`/`setDebugLayers`, found through libvulkan.so's dependencies) before EGL starts, so the loader picks it up from the app's lib dir. Exports only the enumeration functions and `VK_LAYER_FP_shader_fixGet*ProcAddr` (never plain `vk*` entry points). Vader Immortal's lightspeed shaders (Klownicle, GitHub #49). |
 | `xrlayer/` | `linux-arm64/libxr_frameport_timefix.so` + `XR_APILAYER_FRAMEPORT_timefix.json` | OpenXR API layer for Windows PC VR games under Proton on the Frame (glibc aarch64, built freestanding with the NDK's clang), on by default (patch `pcvr.xr_timefix`). Retries `xrCreateInstance` as an OpenXR 1.0 app when the runtime rejects 1.1 (the Frame's SteamVR runtime does, and Proton 11's VR helper asks for 1.1). Also emulates `xrConvertTimespecTimeToTimeKHR`/`xrConvertTimeToTimespecTimeKHR` if the runtime refuses them (the Frame's Android runtime does; its Linux runtime, used by Proton, supports them as of 2026-09-29 — so this part is only a fallback; Proton's wineopenxr needs them for `XR_KHR_win32_convert_performance_counter_time`, which Revive requires) with the adapter's xrWaitFrame-calibrated offset, and drops the extension from xrCreateInstance if the runtime rejects it. Enabled per game by the Proton launch.sh (`XR_API_LAYER_PATH`, `XR_ENABLE_API_LAYERS`). `tests/test_xrlayer.py` builds it for x86_64 and drives it via ctypes. |
 | `oculushmd/` | `win-x64/fp_oculushmd.exe` | PC VR counterpart of overport's `patch_oculus_unreal` (patch `pcvr.oculus_unreal`, default for Unreal Rift games on the Frame). Unreal's OculusHMD and LibOVR's `ovr_Detect` only start when the Windows named event `OculusHMDConnected` exists and is signalled (the Oculus service creates it). `fp_oculushmd.exe <command line>` creates it (manual reset, signalled), runs the command (Revive's injector) in a job object and keeps the event until every process in the job — the game and its children — has exited (fallback without job support: 3 minutes); returns the command's exit code and logs `FramePort oculushmd: …` to stderr (launch.log). Freestanding Windows x64 console exe (no CRT, no Windows SDK): the NDK's clang + `lld-link /Brepro` with a kernel32 import library generated by `llvm-dlltool`, so it's byte-reproducible. Tested on Windows from WSL with a build whose event name is `-DEVENT_NAME=L"…"` (the Oculus service owns the real event on a PC with the Oculus app). |

+// functions below (same strings, shorter, NUL-padded) and adds this library to its DT_NEEDED. Keys without a
+// destructor become slots in one per-thread table that lives under a single real key; keys with a destructor, and
+// every other library, keep using real keys. Approach and the original helper: Klownicle (GitHub #198), verified in
+// the headset; this is FramePort's own implementation of it.
