+Steam library scheduling (#305, agent v99): `install.steam_library` = now/later/off; agent `library_mode` persists it.
+Automatic restarts also hold on a fresh local `frameport-app/gui.alive` (10 s; existing 12 h cap).
+Later journals changes and installs steam.service ExecStartPre/ExecStartPost hooks to reapply after Steam's exit
+writes and verify before clearing; preserve this ordering and avoid locking across systemctl's startup hooks.
+Off Play (also pending Later Play) uses detached systemd-run launch.sh, with no shortcut/devkit registration;

+# Controller buttons
+
+Quest games usually bind Quest Touch controllers. Steam Frame has a d-pad and View button on the left controller,
+and an A/B/X/Y diamond and Menu button on the right. Without a game's own Frame bindings, SteamVR maps Touch X/A
+to the bottom button and Touch Y/B to all three top buttons. View sends Touch Menu. The right X and Y therefore
+send Touch B, rather than the left-hand X and Y of a Quest controller.
+
+**Controller buttons** chooses an alternative for Quest games running through FrameBridge:
+
+- **SteamVR default (0)** leaves SteamVR's Touch remapping in place. This is the initial default.
+- **Mirror (1)** uses every face button. On each controller, bottom and inner send X/A; top and outer send Y/B.
+- **Quest pair (2)** uses two face buttons per controller, diagonally placed like Touch. The other face buttons
+  send no Touch input.
+
+![Quest Touch reference and the three Steam Frame button mappings](images/controllers/quest-buttons.svg)
+
+The small label identifies the physical button; the larger label is the Touch input the game receives. Blue is
+X/A, orange is Y/B or Menu, and a dash means no Touch input. Left and right refer to the hand holding the controller.
+
+<!-- quest-buttons-table:start -->
+| Frame input | SteamVR default (0) | Mirror (1) | Quest pair (2) |
+|---|---|---|---|
+| Left d-pad ↑ | Y | Y | — |
+| Left d-pad ↓ | X | X | X |
+| Left d-pad ← | Y | Y | Y |
+| Left d-pad → | Y | X | — |
+| Left View | Menu | Menu | Menu |
+| Right A (bottom) | A | A | A |
+| Right B (right) | B | B | B |
+| Right X (left) | B | A | — |
+| Right Y (top) | B | B | — |
+| Right Menu | — | — | — |
+| Left bumper | — | — | — |
+| Right bumper | — | — | — |
+<!-- quest-buttons-table:end -->
+
+The table describes button clicks and face-button touches. View sends Menu click only. Triggers, grip pressure,
+thumbsticks, tracked poses and vibration keep their corresponding Touch bindings.
+
+## Choose a mode
+
+For one game, open its **Game settings → Controllers → Controller buttons**. Choose **Use global default** to
+follow Settings, or select a specific mode to keep an override for that game. An explicit **SteamVR default**
+keeps mode 0 even when the global choice is Mirror or Quest pair.
+
+For the library default, open **Settings → Controllers**. The diagram follows the selected mode. New installs
+and configuration updates use this default for games without an override. With a Frame connected, choose
+**Apply to installed games now** to send it to installed Quest games that follow the global default. Overrides
+are kept. Changing the default does not mark every game as needing an update.
+
+Changes take effect at the **next launch**. Close and relaunch a running game.
+Games installed before this feature need **Update on Frame** once for the mode to work.
+
+The CLI can change an installed game's runtime setting:
+
+```sh
+frameport settings <pkg> quest_buttons=2
+```
+
+Use `0` for SteamVR default or `1` for Mirror. This command writes the installed settings directly; it does not
+save a per-game recipe override. To keep the value through later installs and global applies, also save it in
+the recipe, or use Game settings:
+
+```sh
+frameport recipe <pkg> --set quest_buttons=2
+```
+
+## Limits
+
+- SteamVR's binding UI can still override these suggested bindings. Check custom bindings if the result differs
+  from the diagram.
+- Bumpers have no Touch counterpart and are unbound. Thumbrest touch is dropped; the Frame profile has no
+  corresponding input. System buttons keep their runtime role.
+- Mirror and Quest pair require the Frame runtime's `XR_VALVE_frame_controller_interaction` extension. If it is
+  absent, FrameBridge logs that fact and leaves SteamVR's remap in place.
+- Games suggesting their own Frame Controller bindings keep those bindings and continue seeing the Frame
+  Controller profile, even if they also suggest Touch bindings. These modes do not replace the game's own mapping.
+- Touch suggestions using bare pose, trigger, squeeze or button paths are translated too; explicit components
+  such as `/pose`, `/value`, `/click` and `/touch` are also supported where the mapping provides them.
+- Finger proximity emulation (`proximity_emul`) continues to work with Mirror and Quest pair. Dropping the
+  unsupported thumbrest path does not disable proximity emulation from the other touch inputs.
+- The setting applies to Quest VR games, including 32-bit games through the bridge. It does not change PC VR or
+  flat Android Steam Input layouts.
+
+The mapping follows [Valve's Frame Controller input reference](https://partner.steamgames.com/doc/steamhardware/steamframe/input)
+and the [shared mapping data](input/quest_buttons.json). To regenerate the diagram, app illustrations and table,
+run `uv run python scripts/controller_diagram.py`; add `--check` to verify them without writing files.

+
+OutRun Quest VR (`org.outrun.quest.vr`, its own Khronos loader, no OVRPlugin) logs "Rec.709 color space unavailable" right after xrCreateInstance and quits ~20 s later without a session: the Frame's runtime (and OVRPort's dispatcher) list no XR_FB_color_space. Adapter setting `fb_color_space` (off by default, `native/adapter/color_space.c`) offers the extension when the runtime lacks it, strips it from the runtime's create info, fills XrSystemColorSpacePropertiesFB with Rec.709 and answers xrEnumerateColorSpacesFB / xrSetColorSpaceFB (no conversion: the runtime has no API for it). The functions are reachable through FrameBridge's xrGetInstanceProcAddr and `framebridge_extension_proc` (xrshim); OVRPort's fixed dispatcher table can't forward them, hence off by default. Not yet tried on the device (the build was not downloaded: it ships Sega's game data). Log: `color_space: emulating XR_FB_color_space`.

+sets `ro.product.model=Lepton`, manufacturer `Valve`, device `lepton_arm64_only`. A `LEPTON_GFXRECON_*` boot-property
+line cannot replace existing write-once `ro.*` values. Removed the WIP headset property injection. Android
+`Build.MODEL` stays Lepton. A general app-start dex/reflection override is follow-up: the existing `Dex.return_early`
+tooling replaces method bodies, but does not supply a universal early startup hook that safely sets Build fields.
+
+OVRPlugin logged `venderId 10291, systemName Oculus Quest2` even with FrameBridge rewriting the name. The APK's
+`lib/arm64-v8a/libopenxr_loader.so` dispatcher sits above FrameBridge: `xrGetSystemProperties` at VA `0x18554`
+overwrites the name (`0x18620`–`0x18638`, string at file/VA `0x6034`) and returns its own
+`XR_META_headset_id` (`0x186e8` loads address `0x29338`, `0x18778`–`0x1877c` copies 16 bytes;
+UUID file offset `0x21338`). Vendor id remains 10291. A lower-layer-only override cannot fix those answers.
+
+Disassembly of the supplied Unreal `libOVRPlugin.so`:
+
+- `ovrp_GetSystemHeadsetType` at `0x251730` calls `ovrp_GetSystemHeadsetType2` at `0x247bb0`, which calls the
+  `0x2590b0` thunk → `0x292f80`.
+- System properties' name is copied to the global std::string `0x62d328` at `0x261b30`–`0x261b3c`.
+  `0x261b9c`–`0x261bb4` stores the headset-id-present flag (`0x62d2c0`) and UUID (`0x62d2c1`).
+- `0x292f80` checks that flag. When present it compares the UUID, in inline 64-bit constants, returning
+  Quest 1 = 8 (`0x293134`), Quest 2 = 9 (`0x2931ac`), Pro = 10 (`0x2931b8`),
+  Quest 3 = 11 (`0x2931c4`), Quest 3S = 12 (`0x293060`–`0x29309c`). Unknown UUID → 9.
+- Only without the UUID does `0x2930a8` fall back to systemName (older Quest/Pro names, default 9).
+  `0x292d60` is a separate product-name normalizer: it recognizes newer Meta names but returns the generic
+  `Meta Quest` for known Quest products. It is not the headset-type selector. Android Build is not consulted
+  in the traced headset-type path.
+- Cross-check: the available armv7 OVRPlugin's Thumb entry `0x120c5c` → thunk `0x12bc38` → `0x148ac8`
+  likewise tests UUID first (16-byte comparisons), then name at `0x148b1a`. This older build recognizes through
+  Quest 3 (return 11 at `0x148b14`), not Quest 3S. It is consistent with the Unreal mapping for Quest 2/Pro/3.
+
+Raw XrUuidEXT byte order (hyphens just group sequential bytes; do not swap GUID fields):
+
+| Model | UUID | Unreal headset type |
+| --- | --- | --- |
+| Quest 2 | `3064f239-15ed-4722-a659-5ea1ecd899c2` | 9 |
+| Quest Pro | `b58443c9-df86-40cd-8918-2a278e18ab71` | 10 |

+| Quest 3S | `9510492b-0d42-4872-bcf4-fb1a8def6f0e` | 12 |
+
+`device.headset_model` now applies at APK stage after FrameBridge. It verifies original name, UUID and the
+instructions loading both in the known dispatcher before writing either. Unknown builds fail with an explicit
+unsupported-dispatcher message and a Quest 2 escape hatch. Same-size data edits only: NUL-padded 14-byte name and
+16-byte UUID. Quest Pro uses the short dispatcher label `Quest Pro` because `Meta Quest Pro` plus NUL needs 15 bytes;
+its UUID selects type 10. Quest 2 changes no dispatcher bytes and adds no embedded headset setting (native default preserves the old name).
+FrameBridge retains the full standard name override
+for apps calling it directly; setting 2 preserves its original result. No UUID extension is invented in FrameBridge.
+
+Owner verification: rebuild/reinstall Asgard's Wrath 2 with Quest 3 selected. Capture the OVRPlugin line containing
+`venderId 10291, systemName Meta Quest 3`, and its `HeadsetId:` line (16 hex bytes matching Quest 3 above).
+Capture any game/OVRPlugin headset-type line: expect `Meta_Quest_3` / `Quest_3` / numeric 11 if the build logs it;
+absence of such a line is not proof of failure. In the headset check both named graphics options become available,
+can be enabled and persist after restart. Check actual runtime refresh/pacing separately when selecting 90 Hz;
+identity alone does not implement refresh-rate support. Rebuild with Quest 2 for the control: original `Oculus Quest2`,
+original Quest 2 UUID, type 9 if logged, and previous option visibility. Also smoke-test a Unity OVRPlugin game
+with the default Quest 3 choice for regressions. No device access was used during implementation.
+
+## Quest controller mode (`quest_buttons`, 2026-10-17)
+
+Adapter setting `quest_buttons` (0 SteamVR default, 1 Mirror, 2 Quest pair; contract docs/input/QUEST_BUTTONS.md,
+user page docs/CONTROLLERS.md). FrameBridge enables `XR_VALVE_frame_controller_interaction` and, after a game's Touch
+suggestion succeeds, suggests `/interaction_profiles/valve/frame_controller_valve` bindings translated from the
+accepted Touch set (SteamVR uses a Frame binding before its own Touch remap: Touch B/Y on all three top buttons).
+
+Headless check on the device (I Am Cat, Unity + OVRPlugin, mode 2, `input_diag=1`): the runtime offers and enables the
+extension in a Lepton app, and accepts the generated Frame suggestion (`quest_buttons: frame_controller bindings
+(mode 2, 27 bindings, 7 dropped): 0`); the game's Touch (34 paths) and hand-interaction suggestions were accepted as
+before; 72 fps, no new errors. Translations as in the JSON: left `x/*` -> `dpad_down/*`, `y/*` -> `dpad_left/*`,
+`menu/click` -> `view/click`. Not provable headless (tracking needs the headset worn): that SteamVR then reads the
+buttons from the Frame binding; one launch in the headset settles it.
+
+Pitfall seen during the test: OVRPort runs from two sessions on the same data folder share
+`overport-workspace/dec/working.apk` and fail at once (`OVRPort failed (exit 1)`, `FileAlreadyExistsException` in
+OVRPort's own output, which the CLI doesn't print without a verbose reporter). Build one game at a time per data folder.

+- Right: `a`, `b`, `x`, `y`, `menu` (click and touch). The face diamond is A bottom, B right, X left, Y top.
+- Both: `system`, `bumper`; `squeeze` and `trigger` (click, touch, value); `thumbstick` (vector, x, y, click,
+  touch); `grip/pose`, `aim/pose`. Haptics use `/user/hand/<hand>/output/haptic`.
+
+SteamVR prefers a game's Frame Controller binding. Without one, its Touch remap sends left d-pad down as Touch X
+and left/up/right as Touch Y; right A as Touch A and X/Y/B as Touch B. Left View sends Touch Menu.
+FrameBridge's `quest_buttons` preference (`0` default, `1` Mirror, `2` Quest pair) enables the extension when offered
+and suggests a Frame binding translated from the game's Touch suggestions. Common pressure/trigger/thumbstick,
+pose and haptic paths keep their Touch counterparts; thumbrest touch and system click are dropped, bumpers stay
+unbound. The player's SteamVR custom bindings can override suggestions. This works on both bridge ABIs, without

+(supersampling) changes the game's render resolution: higher is sharper but slower. Climb 2 foveation still requires

+## Steam library scheduling
+
+Agent v99 holds automatic shortcut restarts while the local app's
+`~/.local/share/frameport-app/gui.alive` heartbeat is under ten seconds old, as well as while a game or Desktop Mode
+is open. Closed/crashed GUIs expire; the existing twelve-hour hold limit still applies.
+
+`library_mode` accepts `now` (default), `later`, and `off`; FramePort stores its preference as
+`install.steam_library`. Later writes shortcuts and journals packages/removals in
+`~/.local/share/frameport/library-pending.json`. Steam rewrites shortcuts.vdf on exit, so a user drop-in
+`~/.config/systemd/user/steam.service.d/frameport-library.conf` reapplies the journal in ExecStartPre, after the
+previous session has exited. ExecStartPost verifies the entries and uses the existing live devkit fallback if Steam
+removed them. The journal is cleared only after success, and survives agent/app exit and reboot. The hooks share the
+shortcut worker lock; an active worker performs its own write/verification instead. Both hook lines start with
+`-` and run under `/usr/bin/timeout -k 5 20` (present on SteamOS; `-` ignores exit codes, including 127 for a missing
+interpreter or agent, but not a hook that hangs until the unit's 90 s start timeout); ExecStartPre also has its own
+SIGALRM deadline. ExecStartPost only starts the verification as the transient unit `frameport-library-verify`
+(`--no-block`, RuntimeMaxSec 300), so Steam's start never waits for its Steam/devkit waits. The pre hook leaves
+shortcuts.vdf alone when nothing is pending. The drop-in is removed (and the user manager reloaded) as soon as the
+mode isn't `later` and nothing is pending, and by purge; an otherwise empty `steam.service.d` goes with it.

+This automatic application targets SteamOS's `steam.service`; if Steam is started outside that service, use

 > Lepton runs VR apps headless: their Android window is never shown, so it never gets keyboard focus and no key press (Steam's on-screen keyboard, a USB/Bluetooth keyboard, Type on Frame) reaches the app's text fields. With Lepton's lepton-show-flatscreen marker the window is shown (behind the VR view, which keeps working) and Steam's keyboard opens for a selected text field. Steam lists the shown window as "Gamescope" (the Frame's compositor). Pairs with "Make Unity text fields work without a system keyboard".

+| Quest 3-only options missing; OVRPlugin logs `venderId 10291, systemName Oculus Quest2` (#373, Asgard's Wrath 2) | OVRPort's dispatcher overwrites FrameBridge's name and supplies a Quest 2 `XR_META_headset_id`; OVRPlugin prioritizes that UUID | `device.headset_model`: Quest 3 by default, per-game Quest 3S / Quest Pro / Quest 2; rebuild the APK. Byte-checked dispatcher name + UUID edit; Quest 2 leaves the dispatcher unchanged. See DEVICE_NOTES 'Per-game headset identity' |
 | Startup exits through `libxlua.so (lj_err_throw)`, then Unity aborts in mutex cleanup; captured Lua error is `bad light userdata pointer` (GitHub #257, BattleTalent 4.7) | This older LuaJIT encodes lightuserdata in 47 bits; Frame supplies valid wider native pointers. 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. A `lj_err_throw` cleanup stack without the original error message is insufficient to infer this cause |
 | A GL4ES Team Beef game draws stretched triangles or spikes across characters and the scene (GitHub #191, Lambda1VR) | The newer GL shim exports GLES draw functions that intercept GL4ES's desktop OpenGL calls, bypassing its client-array and immediate-mode translation | `frame.tbxr_vendor` keeps the shim's five draw symbols private when the APK bundles `libgl4es.so`. 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 Team Beef game reports a crash after manually quitting: `fdm_injection_xrDestroySwapchain` → `TBXR_LeaveVR` (GitHub #191, Lambda1VR) | Valve's foveation layer dereferences a null pointer during swapchain cleanup | Triage `tbxr-fdm-shutdown-crash` identifies this as a teardown crash, separate from startup and distorted geometry.

 | Updating a flat Android app after saving its recipe fails with `no OVRPort patches selected` (GitHub #271, Plezy) | older FramePort loads the saved recipe without restoring its unchanged-install setting or applying the flat-app build rules, then tries an empty VR conversion | update FramePort: saved recipes keep `as_is`, and flat apps still skip OVRPort; existing catalog-derived recipes refresh at the next app update. Until then, enable "Install as is" for an app whose APK needs no fixes |
 | A launch test suggests a patch (for example triage `sdl-no-clipboard` → `frame.sdl_clipboard`) but the game page doesn't show it / lists it as not applicable; or a game added long ago lacks warnings newer ones get (Android version, web wrapper, missing OBB) (GitHub #104, Dramatic Shape) | the library entry was analyzed by an older FramePort: the analysis field the patch reads (`sdl_java`, `min_sdk`, `web_wrapper`, `expects_obb`, …) is missing, so `applies()` is false | entries whose `analysis.extra.analysis_version` is below `detect.ANALYSIS_VERSION` are analyzed again at the GUI's start (background) and before a build (`pipeline.refresh_analyses`); by hand: game menu → "Analyze again", then Update on Frame. An unreadable APK is marked `analysis_failed` (retried after the next version bump). Adding an analysis field: bump `ANALYSIS_VERSION` |
 | FDM layer loads but diagnostic logging reports `fdm_injection_CreateInstance: skipped` | Layer loading alone does not enable injection on the tested SteamOS 0.4.5 build; a skipped helper instance alone also does not establish game-wide inactivity | Opt-in `device.foveation` mode `tracked`: loads Valve's layer and sets `FDM_DEBUG=enable`. Batman probe reached foveated render passes with changing per-eye offsets. Validate graphics and matched gameplay GPU time; do not enable globally.

With `foveation_fix=0` + `foveation_storage_fix=1` the adapter logs `foveation_storage_fix: shared allocation SUBSAMPLED cleared` for the eye swapchains | `device.foveation` (tracked/fixed) now also sets `foveation_storage_fix=1`, which clears SUBSAMPLED whatever `foveation_fix` is (generic version of Batman's OVRPlugin allocation fix).

+# Quest controller mode: contract (`quest_buttons`)
+
+This file is the contract between the native (FrameBridge) and app/docs halves of the feature. The mapping itself
+lives in [`quest_buttons.json`](quest_buttons.json); everything else follows it.
+
+## Problem
+Quest games suggest bindings only for `/interaction_profiles/oculus/touch_controller`. The Steam Frame controllers
+are two gamepad halves (Valve: https://partner.steamgames.com/doc/steamhardware/steamframe/input):
+- left: `dpad_up|dpad_down|dpad_left|dpad_right` (click, touch), `view` (click, touch), `system`, `bumper`,
+  `squeeze` (click, touch, value), `trigger` (click, touch, value), `thumbstick` (vector, x, y, click, touch),
+  `grip/pose`, `aim/pose`, `output/haptic`
+- right: `a|b|x|y` (click, touch), `menu` (click, touch), `system`, `bumper`, and the same squeeze/trigger/thumbstick/
+  poses/haptic.
+
+SteamVR uses a game's Frame Controller binding first; without one it remaps Touch: Touch B/Y -> the three top buttons
+(left d-pad left/up/right, right X/Y/B), Touch A/X -> the bottom one, Touch menu -> View (mode `0` in the JSON).
+
+## Setting
+FrameBridge adapter setting `quest_buttons` (int, read from settings like every other key; numbers only):
+- `0` = off (default): FrameBridge does nothing new, SteamVR's remap applies.
+- `1` = Mirror, `2` = Quest pair: see `modes` in the JSON.
+
+Library setting `input.quest_buttons` (0/1/2, default 0) = the global default, used at install for games whose recipe
+doesn't name `adapter.quest_buttons`.
+
+## Native behaviour (FrameBridge)
+1. At `xrCreateInstance`, when `quest_buttons` != 0 and the runtime lists `XR_VALVE_frame_controller_interaction`,
+   add it to the enabled extensions (the adapter already rewrites this list). Not listed -> log and stay off.
+2. When the game's suggestion for the Touch profile succeeds (directly, or through `profile_remap`'s
+   `remap_to_touch`), suggest a translated set for `/interaction_profiles/valve/frame_controller_valve`:
+   - each binding `/user/hand/<hand>/input/<touch input>[/<component>]` maps by the JSON: `common` 1:1, button
+     `x|y|a|b` + `/click` or `/touch` -> each listed Frame button + the same component, `menu/click` -> listed
+     Frame button + `/click`; `output/haptic` 1:1; anything in `dropped` or unknown is left out.
+   - a later Touch suggestion by the same game replaces the Frame set (suggest again; the last call per profile
+     wins in OpenXR).
+   - a failed Frame suggestion is logged and ignored: the game's own call result is never changed.
+3. `xrGetCurrentInteractionProfile`: with `quest_buttons` != 0, a `/valve/` answer is reported as Touch even when
+   `controller_fix` is off.
+4. Log lines (logcat tag of the adapter):
+   - `quest_buttons: extension XR_VALVE_frame_controller_interaction enabled` / `... not offered by the runtime`
+   - `quest_buttons: frame_controller bindings (mode N, K bindings, D dropped): <XrResult>`
+   - with `input_diag=1`: `input_diag: quest_buttons <touch path> -> <frame path>` per added binding.

+# App stream: Quest controller buttons
+
+## Implementation
+
+- Added `adapter.quest_buttons` (integer, default 0), common Controllers choice with SteamVR default / Mirror /
+  Quest pair. It is available on both bridge ABIs, is not an XR shim setting and has no detection suggestion.
+  No agent, patch, setting or analysis revision was changed.
+- `patches.settings.adapter_settings(..., defaults=...)` and the headset identity wrapper stay pure.
+  `core.controllers.effective_adapter_settings` supplies the library preference at build, install, live suggestion
+  and dialog boundaries. Recipes override it, including an explicit 0. APK `libframe_settings.so` and installed
+  `settings.conf` receive the effective value.
+- Recipe/APK/configuration fingerprints do not read the global preference. The existing agent updates its
+  configuration fingerprint during `set_settings`; `game_update.configuration_matches` therefore accepts all
+  three inherited controller values, while still checking explicit overrides and every other configuration field.
+  An offline test exercises the real agent handler to prevent a global apply making the library outdated.
+- Game settings has a **Use global default (mode)** option. Saving unchanged inherited settings keeps the recipe
+  unchanged; choosing SteamVR default stores an explicit 0. Reset restores the effective global value.
+- Settings → Controllers stores `input.quest_buttons`, shows a diagram for the choice, and offers **Apply to
+  installed games now** while connected. The existing FIFO Frame tool job pushes only `quest_buttons` through
+  `target.set_settings`. It skips non-Quest games, flat Android apps known to the library, and recipe overrides.
+  A library-less install with an override listed in its deployment is also skipped. Cancellation is checked per game.
+- The CLI already has `settings <pkg> quest_buttons=N` (runtime only) and `recipe <pkg> --set quest_buttons=N`
+  (persistent recipe). No global CLI option was added: there is no existing general library configuration command,
+  and `settings` specifically writes an installed game's settings. The global preference is available in the GUI.
+- `scripts/controller_diagram.py` reads the unmodified JSON contract and literal Portal theme colours. It generates
+  the full four-panel SVG, three bundled compact SVGs and the marked Markdown table. `--check` checks all outputs;
+  `--compact --mode N [--out path]` generates just one pair. Bundled images use the existing glyph asset copy and
+  URL path, with no image bytes or filesystem reads in the diagram render helper.
+- Added the user guide and README/install/playbook/runtime links, regenerated the patch docs, site map and
+  translation template. The only agent edit corrects the old D-pad comment. No shared smoke script was edited.
+
+## Offline checks and visual review
+
+Commands use the existing venv without resolving packages. The default uv cache is read-only in this sandbox;
+plain `uv run` attempted an editable metadata refresh requiring unavailable cached build dependencies.
+
+```sh
+export UV_CACHE_DIR=/tmp/frameport-qb-uv
+export UV_NO_SYNC=1
+uv run pytest -q
+uv run python scripts/patch_docs.py --check
+uv run python scripts/controller_diagram.py --check
+uv run python scripts/i18n_extract.py --check
+```
+
+The focused settings, update, translation, patch and UI tests passed (147 passed, 2 skipped before the final
+agent-fingerprint regression; the follow-up controller/update/UI-state run passed 89 tests, with the existing
+socket test deselected). Final full suite: **2015 passed, 45 skipped, 12 failed, 16 setup errors** (67.76 s). All 28 remaining failures/errors
+are existing local-socket tests rejected by the sandbox (deeplink, devkit, install links, link updates, livestream,
+setup URL and pairing). The translation failure from the first run was fixed. The changed feature's tests pass;
+the full suite cannot be reported as passing in this environment. The log is local at `/tmp/qb-app-final-pytest.log`.
+Patch docs, diagram and translation generation checks pass.
+
+The real Flet smoke command was attempted:
+
+```sh
+FRAMEPORT_NO_UPDATE_CHECK=1 FRAMEPORT_NO_ANNOUNCEMENTS=1 \
+  uv run python scripts/ui_smoke.py --out .shots --fake-frame \
+  --game com.BithellGames.Arcsmith --only tools,game-settings-dialog
+```
+
+It cannot start here: the sandbox rejects even creation/binding of loopback sockets (`PermissionError: [Errno 1]
+Operation not permitted`). Flet reports it cannot bind its server on port 8557. Consequently no Settings or Game
+settings PNG was produced or inspected. This is an outstanding maintainer validation step, not a passed UI check.
+No Frame or external network connection was attempted.
+
+The diagrams were rendered offline with ffmpeg and visually inspected. Both are readable, with correct left/right
+positions and dimmed unbound buttons. Local, uncommitted review PNGs:
+
+- `.shots/quest-buttons.png` — all four panels.
+- `.shots/quest-buttons-compact.png` — the app's Mirror image.
+
+The Impeccable mechanical detector returned no findings on the changed UI files; targeted Ruff and whitespace
+checks passed.
+
+## Capture the actual UI on a machine that permits loopback
+
+Use a test library in `FRAMEPORT_HOME` containing a Quest game. `ui_smoke.py` has no Controllers section option,
+so this temporary wrapper reuses its real browser/driver and scrolls the two relevant surfaces. It does not change
+tracked files. Set `pkg` to a Quest game in that test library first.
+
+```sh
+pkg=com.example.questgame
+cat > .home/capture_controllers.py <<'PY'
+import sys
+import time
+sys.path.insert(0, 'scripts')
+import ui_smoke as smoke
+
+original_driver = smoke.driver
+

+

+FRAMEPORT_NO_UPDATE_CHECK=1 FRAMEPORT_NO_ANNOUNCEMENTS=1 \
+  uv run python .home/capture_controllers.py --out .shots/controllers \
+  --fake-frame --game "$pkg" --only tools,game-settings-dialog
+```
+
+Inspect `.shots/controllers/01-settings-controllers.png` and
+`.shots/controllers/02-game-settings-controllers.png` at 1280×820; repeat with `--viewport 1024x768`. Verify the
+choice text, diagram, explanation and apply button fit; scroll a little in the dialog if the game's relevant
+Picture settings make offset 400 miss the row. Also choose all three modes and the global option in the actual
+GUI, checking that the diagram changes and re-opening preserves inheritance or the explicit override.
+
+## Exact device verification after native integration
+
+These steps are for the maintainer; none were executed in this stream. Merge the native stream and its adapter
+artifacts first. Use a Quest game that binds all four Touch face buttons (and, separately, an available 32-bit
+bridge game). Set `pkg` to its real library package; keep the same `FRAMEPORT_HOME` used for that test library and
+its paired Frame. Close the game before rebuilding/installing.
+
+1. Build/install the integrated adapter once. With global mode Mirror and the game's **Use global default**
+   selected, run:
+
+   ```sh
+   pkg=com.example.questgame
+   uv run frameport build "$pkg"
+   uv run frameport install "$pkg" --force --apk-only
+   uv run frameport settings "$pkg" input_diag=1
+   ```
+
+   Confirm the build's `lib/<abi>/libframe_settings.so` contains `quest_buttons=1`. The following PC-side inspection
+   reads the APK path recorded by the build:
+
+   ```sh
+   uv run python - "$pkg" <<'PY'
+   import sys, zipfile
+   from frameport.core import library
+   with zipfile.ZipFile(library.game(sys.argv[1])['build']['apk']) as apk:
+       for name in apk.namelist():
+           if name.endswith('/libframe_settings.so'):
+               print(name, apk.read(name).decode())
+   PY
+   ```
+
+2. For each mode, write it and launch from Steam/FramePort Play while wearing the headset:
+
+   ```sh
+   uv run frameport settings "$pkg" quest_buttons=1 input_diag=1
+   # Close the game, then repeat with quest_buttons=2, then quest_buttons=0.
+   ```
+
+   On the Frame, set `pkg` to the same package and locate its actual base (works for internal storage or another
+   drive). After each launch inspect:
+
+   ```sh
+   pkg=com.example.questgame
+   base=$(python3 -c 'import json,sys; print(json.load(open(sys.argv[1]))["base"])' \
+     "$HOME/Applications/quest-frame/$pkg/deployment.json")
+   grep '^quest_buttons=' "$base/settings.conf"
+   grep -E 'quest_buttons:|input_diag: quest_buttons' "$base/launch.log"
+   ```
+
+   Expected for modes 1/2:
+
+   ```text
+   quest_buttons: extension XR_VALVE_frame_controller_interaction enabled
+   quest_buttons: frame_controller bindings (mode N, K bindings, D dropped): <XrResult>
+   input_diag: quest_buttons <touch path> -> <frame path>
+   ```
+
+   `N` is 1 or 2, `K` is nonzero, and the Frame suggestion result must indicate success. Input diagnostics must
+   match the JSON paths. For mode 0 there should be no new FrameBridge Frame suggestion. Check the physical face
+   buttons against every row of `docs/CONTROLLERS.md`: Mirror repeats X/A on bottom+inner, Y/B on top+outer;
+   Quest pair leaves left up/right and right X/Y unbound. Left View sends Menu in every mode. Check touch actions
+   where the game exposes them, triggers, grip pressure, sticks, poses and haptics. Bumpers are unbound. Repeat on
+   the 32-bit bridge ABI. Existing custom SteamVR bindings should still take precedence.
+
+3. Verify global apply with two installed games: one following the global choice, one explicitly set to SteamVR
+   default (0). Set Settings → Controllers to Quest pair; click **Apply to installed games now**. Expect one FIFO
+   Frame tool job, `quest_buttons=2` only on inherited games, and the explicit game's 0 retained. Check that neither
+   game gains an Update ready badge solely from the global change/apply. Re-open Game settings: the inherited
+   choice says **Use global default (Quest pair)**. Relaunch to verify the mode; a running game keeps its old mode.
+   Also test changing an explicit mode and then resetting to the global choice.
+
+4. If an extension-less runtime is available, modes 1/2 must log
+   `quest_buttons: extension XR_VALVE_frame_controller_interaction not offered by the runtime` and retain the
+   SteamVR default mapping without a launch failure. Otherwise leave this case to the native offline tests.
+
+5. Undo: set the global choice to SteamVR default and apply to inherited installed games. Restore any pre-test
+   per-game choices in Game settings, and disable diagnostics:
+
+   ```sh
+   uv run frameport settings "$pkg" quest_buttons=0 input_diag=0
+   ```
+
+   A persistent test override made with the recipe CLI can be removed with
+   `uv run frameport recipe "$pkg" --disable adapter.quest_buttons`; then select the global choice and save in
+   Game settings to push its current effective value.
+
+## Contract questions / remaining integration work
+
+- The contract translates successful Touch suggestions. A game suggesting only its own Frame bindings is
+  unaffected. If a game suggests both Touch and its own Frame profile, ordering/priority is not specified by the
+  contract; verify with the native stream before claiming both-profile games are unaffected. The user guide
+  qualifies this limit accordingly.
+- No device claims were added. The runtime reference marks new-mode verification pending integration.
+- A direct CLI `settings` write is intentionally temporary relative to the recipe/global preference. Use
+  `recipe --set quest_buttons=N` or the dialog for a persistent per-game override.
+- Actual UI screenshots and the socket-dependent full-suite tests require a less restricted local environment.
+
+## Round 2
+
+- Global apply still writes every inherited Quest install, but separates games ready for the next launch from
+  games that need **Update on Frame first**. The job result supplies the completion toast, so both show the same
+  counts. The Settings explanation includes the one-time update requirement.
+- `_build_inputs_changed` also checks the converter and source APK, so it cannot decide adapter support alone.
+  Its manifest reader was extracted into `build.native_checksums` and is shared by `_build_inputs` and the
+  controller check. Only adapter entries are compared. Missing/different checksums or an unknown/different
+  installed APK are reported as needing an update; unrelated artifact changes do not affect this count. This is
+  deliberately conservative when an older adapter already supports the feature but differs from the bundled one.
+- The section reads its default once into a local snapshot, uses that for the dropdown and preview, and updates it
+  on selection. Regression tests check the single read and that the existing preview control changes in place.
+- The user guide now covers game-owned Frame bindings/profile preservation, bare binding paths and continued
+  proximity emulation. This supersedes the earlier question about games suggesting both Frame and Touch profiles.
+  The maintainer's triangle arrows and shared JSON were left unchanged.
+- Focused tests: **135 passed, 2 skipped** (`test_controller_preferences.py`, `test_patches.py`,
+  `test_game_update.py`). Patch-doc, translation-template and controller-diagram checks pass; the translation
+  template was regenerated. Targeted Ruff and whitespace checks pass.
+- Device follow-up: on an old/unknown install, choose Mirror and apply globally. Expect its setting to be pushed but
+  the result/toast to count it under **needs Update on Frame first**. Update that game once, apply again, then
+  relaunch: expect it in the next-launch count and the existing mode-1 binding logs described above. Keep a second
+  game with an explicit override and verify it is skipped throughout. Undo by choosing SteamVR default and applying
+  again; restore any per-game test overrides. No device or external network access was used in this round.
+- Final whole suite: **2029 passed, 116 skipped, 12 failed, 16 setup errors** (67.52 s). The remaining failures
+  and errors are the existing local-socket tests blocked by the sandbox, as in Round 1. Full log:
+  `/tmp/qb-app-round2-pytest.log`. No test skips or socket workarounds were added.

+# Quest controller mode: native stream
+
+## Original implementation
+
+- `native/adapter/quest_buttons.c` parses the numeric adapter setting. Only 0, 1 and 2 are accepted; malformed,
+  fractional and out-of-range values select 0 and log `quest_buttons: invalid setting; using 0`.
+- `xrCreateInstance` reuses the existing next-layer extension enumeration. Modes 1 and 2 enable
+  `XR_VALVE_frame_controller_interaction` only when offered, without adding a second copy when the game requested
+  it. An unavailable/failed enumeration disables this feature. Failed instance creation clears the enabled flag.
+- `suggest_frame()` in `session_fixes.c` translates successful Touch suggestions using the tables corresponding to
+  `quest_buttons.json`. It preserves action handles and click/touch components, supports both hands, poses,
+  thumbstick vector/components and haptics, and counts unknown/dropped source bindings. Each input produces at most
+  two Frame bindings. Mode 0 adds no runtime calls or feature logs.
+- Touch Pro/Plus fallback translates the filtered Touch-shaped copy after Touch succeeds. Proximity-emulation
+  additions are deliberately excluded. A later Touch suggestion submits a fresh Frame set. Frame suggestion errors
+  are logged without changing the game's result. A successful game-owned Frame suggestion prevents subsequent
+  automatic Frame suggestions; if it arrives after an automatic suggestion, its runtime call replaces that set.
+- With the setting and extension enabled, `xrGetCurrentInteractionProfile` translates Valve profiles to Touch even
+  with `controller_fix=0`. Existing `profile_remap` then still reports the game's Touch Pro/Plus profile when needed.
+  Input diagnostics continue to show the runtime's original profile and additionally log every translated binding.
+- Both shipped adapter architectures were rebuilt, with updated `artifacts/SHA256SUMS`. No agent, analysis, patch
+  or setting revision was changed. Contract files and the VrApi bridge are unchanged.
+
+## Original offline validation
+
+Commands run with `UV_CACHE_DIR=/tmp/frameport-qb-native-uv` to keep uv cache writes inside the writable sandbox;
+`--offline --no-sync` uses the existing worktree environment without fetching dependencies.
+
+```sh
+FRAMEPORT_NATIVE_TESTS=1 uv run --offline --no-sync pytest -q tests/test_quest_buttons.py tests/test_profile_report.py
+uv run --offline --no-sync python native/build.py --only adapter
+uv run --offline --no-sync python scripts/patch_docs.py --check
+uv run --offline --no-sync pytest -q
+```
+
+The new host harness includes `quest_buttons.c`, `input_diag.c`, and the complete `session_fixes.c`, plus verbatim
+copies of the adapter's exported create-instance/current-profile functions. It compiles with host `cc -Werror`.
+Python derives expected Frame bindings from the unchanged JSON contract, independently of the C mapping table.
+The targeted run passed 73 tests, including the existing profile-report tests. Two consecutive adapter builds
+produced identical SHA-256 hashes for both architectures; the manifest matches both files. Documentation checks pass.
+
+The cached NDK/OpenXR inputs were already present. During the builds, the worktree's ignored `native/.cache` was
+temporarily a local directory containing input symlinks, so shader intermediates were written only inside this
+worktree. The original shared-cache symlink was restored afterward. No inputs were fetched or changed and no device
+was contacted.
+
+Additional native baseline issue: `FRAMEPORT_NATIVE_TESTS=1 ... tests/test_input_diag.py` has an existing failure in
+`test_logs_each_finding_once_and_nothing_when_off`. Its harness requests `input_diag_hook("xrCreateAction")`, which
+the baseline implementation no longer exposes: action diagnostics moved to `session_fixes.c`. Compiling the harness
+against pristine `25e282d`'s `input_diag.c` reproduced the same line-85 failure. That unrelated behavior/test was left
+unchanged.
+
+Full-suite result: **1,993 passed, 116 skipped, 12 failed, 16 errors**. All 28 failing/erroring cases stop at socket
+creation with `PermissionError: [Errno 1] Operation not permitted`: local HTTP fixtures in deep links, link updates,
+devkit, livestream, setup URL, and pairing UI tests. The sandbox disallows even loopback sockets. No feature
+assertion failed. The required unfiltered command was run; a green unfiltered run still requires a host that permits
+local sockets. The socket restriction was not relaxed.
+
+An additional run deselecting exactly those 28 unsupported cases passed: **1,993 passed, 116 skipped, 28 deselected**.
+
+## Integration questions and limits
+
+- The contract has no missing mapping needed by this implementation. The right controller's Menu button has no
+  mapping in modes 1/2; only left Touch `menu/click` maps to Frame `view/click`. Unknown paths, including menu touch
+  and proximity, are intentionally dropped.
+- The game's own Frame bindings win only after its Frame suggestion succeeds. A rejected Frame suggestion does
+  not suppress automatic translation. This avoids disabling working input because the game submitted an invalid set.
+- Headless/host tests cannot establish SteamVR's actual preference for these suggested bindings, physical button
+  layout, capacitive touch behavior, haptics, or whether the installed Frame runtime offers the extension. These
+  require the maintainer's checks below. An empty translated set is submitted and its result logged/ignored like
+  any other Frame suggestion; the runtime can reject it.
+
+## Maintainer device checks (not executed)
+
+Use an isolated `.home` already containing a test library entry, its signing key/toolchain, and a paired test Frame.
+Use a normal Quest OpenXR game and a VrApi game using the bridge. Repeat with a game that suggests only Touch
+Pro/Plus if available. Replace the sample package name with each game's actual package. Stop other games first.
+
+1. Rebuild/reinstall the test game so the new adapter is actually inside the APK. A setting update alone cannot
+   upgrade an already installed adapter. Keep the original `controller_fix` and `input_diag` values for restoration.
+
+   ```sh
+   export FRAMEPORT_HOME="$PWD/.home"
+   export PKG=com.example.game
+   uv run frameport install "$PKG" --force
+   ```
+
+2. Collect a headless startup log for each mode, with `controller_fix=0` and diagnostics enabled. Each launch test
+   stops its game before the next iteration. The script uses the remembered Frame in this isolated home.
+
+   ```sh
+   for MODE in 0 1 2; do
+       export MODE
+       uv run frameport settings "$PKG" quest_buttons="$MODE" input_diag=1 controller_fix=0
+       uv run python - <<'PY'
+   import os
+   from pathlib import Path
+   from frameport.cli import _target
+   from frameport.core.events import Reporter
+
+   target = _target(None)
+   try:
+       result, log = target.launch_test(os.environ["PKG"], Reporter(), seconds=30)
+       output = Path(os.environ["FRAMEPORT_HOME"]) / f"quest-buttons-mode-{os.environ['MODE']}.log"
+       output.write_text(log)
+       print(output)
+       for line in log.splitlines():
+           if "quest_buttons" in line or "controller profile" in line:
+               print(line)
+   finally:
+       target.frame.close()
+   PY
+   done
+   ```
+
+   Expected mode 0: no `quest_buttons:` or `input_diag: quest_buttons` lines. Modes 1/2, if offered:
+
+   ```text
+   quest_buttons: extension XR_VALVE_frame_controller_interaction enabled
+   quest_buttons: frame_controller bindings (mode 1, K bindings, D dropped): 0
+   input_diag: quest_buttons /user/hand/left/input/x/click -> /user/hand/left/input/dpad_down/click
+   input_diag: quest_buttons /user/hand/left/input/x/click -> /user/hand/left/input/dpad_right/click
+   input_diag: quest_buttons /user/hand/left/input/menu/click -> /user/hand/left/input/view/click
+   ```
+
+   `K`/`D` depend on the game. Mode 2 reports `mode 2` and only the first X mapping above. Face-button touch paths
+   keep `/touch`. Frame suggestions must return `0`; a negative result indicates runtime rejection to investigate.
+   A Touch Pro/Plus-only game should also log `controller profile ... -> oculus/touch_controller` and a Frame binding
+   summary. If the runtime lacks the extension, expect
+   `quest_buttons: extension XR_VALVE_frame_controller_interaction not offered by the runtime`, with no translated
+   bindings; input should retain its previous behavior.
+
+3. For each mode, set it with the command below, then Play from the FramePort library or Steam while wearing the
+   headset. Exit through Steam before changing modes; settings are read at process startup.
+
+   ```sh
+   uv run frameport settings "$PKG" quest_buttons=1 input_diag=1 controller_fix=0
+   ```
+
+   Mirror: left down/right = Touch X; left up/left = Touch Y; right A/X = Touch A; right B/Y = Touch B. Quest pair:
+   left down = X, left left = Y, right A = A, right B = B; the unused face buttons should not activate those actions.
+   In both modes left View activates Touch Menu. Check thumbstick movement/click/touch, trigger/squeeze values,
+   trigger touch, tracking/aim, and haptic feedback. Verify both hands remain connected with `controller_fix=0`.
+   Mode 0 should match the previous SteamVR mapping. Capacitive-touch verification needs a game that exposes finger
+   animation or an input sample; absence of a suggested touch action is not a failure of this mapping.
+
+4. Restore settings after stopping the game. The example restores the usual defaults; substitute recorded original
+   values if different. Reinstalling the prior known-good APK also removes the new adapter if an artifact rollback
+   is needed; setting 0 alone disables the feature on the next launch.
+
+   ```sh
+   uv run frameport settings "$PKG" quest_buttons=0 input_diag=0 controller_fix=1
+   ```
+
+For explicit current-profile verification in an OpenXR input sample, call `xrGetCurrentInteractionProfile` for
+`/user/hand/left` and `/user/hand/right`, then `xrPathToString` on each non-null result after action-set attachment.
+With modes 1/2 and `controller_fix=0`, expect `/interaction_profiles/oculus/touch_controller`, or the game's own
+Touch Pro/Plus profile when its binding was remapped. Existing `input_diag` profile lines intentionally show the raw
+runtime answer, so they cannot alone verify the profile returned to the game.
+
+## Round 2
+
+The review fixes supersede the original proximity exclusion, broad Valve-profile rewrite, empty-set submission,
+and failed-instance state handling described above:
+
+1. Added bare `grip`/`aim` to the JSON common mapping and `FRAME_COMMON`; no other contract fields changed.
+2. Current-profile rewriting with `controller_fix=0` requires the exact Frame profile and a successful generated
+   binding set still in effect. A successful game-owned Frame suggestion ends that ownership; failed suggestions
+   leave the last accepted set in effect. Existing `controller_fix=1` behavior is retained.
+3. Frame bindings are generated at the point a Touch set succeeds, including proximity-emulation touch bindings.
+   Direct Touch, Touch Pro/Plus remapping, and rejected-expansion fallback all use the effective accepted set.
+4. An all-dropped translation makes no Frame suggestion and logs
+   `quest_buttons: frame_controller bindings (mode N, 0 bindings, D dropped): not suggested`. An earlier accepted
+   generated set can remain stale; it is intentionally retained because an empty replacement is invalid.
+5. Extension decisions remain local until instance creation succeeds. Only successful creation publishes the active
+   instance and resets binding ownership/Touch-remap state; a failed second attempt preserves the live first state.
+6. One mutex serializes each complete suggestion transaction, including fallback/remapping, Frame generation, and
+   flags. Instance-state publication and current-profile reporting use the same mutex. Internal helpers call the
+   next layer directly and never reacquire it.
+
+Regression tests reproduced items 1–5 before the fixes (21 failed cases). Afterward, the requested host run passed
+97 tests, including timeout-bounded nested proximity fallback and Touch Pro remapping. Diagram regeneration made no
+changes; controller-diagram and patch-documentation checks pass. Both adapter architectures were rebuilt twice with
+identical hashes matching `SHA256SUMS`. The full suite finished with 2,015 passed, 140 skipped, 12 failed and 16 errors;
+all 28 failures/errors are the same sandbox-denied local socket creation described above.
+
+Device follow-up: repeat the install/log/physical checks above, adding `proximity_emul=2` to the mode-1/mode-2 settings
+command for a game exposing finger proximity. Expect translated proximity actions on face-button/thumbstick touch
+and trigger touch, and working finger animation. In an OpenXR sample with `controller_fix=0`, also query profiles
+before any generated set, after a successful generated set, and after the app's own successful Frame suggestion:
+expect Frame, Touch, Frame respectively. Another Valve profile must stay unchanged. Restore the recorded original
+`proximity_emul` setting along with the other settings. No device operations were performed in this worktree.

Fixes for PreyVR's black main menu, the Table Troopers tutorial, Spectre and Escaping Wonderland's endless loading screen, Pinball FX2 VR, BattleTalent, controllers in Hotel Infinity and Spatial Zombies, Scared By Squares, Medieval Dynasty's foveation, Star Wars: Beyond Victory in mixed reality, Titan Isles, PianoVision and Eleven Table Tennis. Curved menus that showed black now show in both eyes.\n- **Clearer reports:** Google Daydream / Cardboard builds get a warning (they can't run on the Frame), and the log check now names failed Meta online requests.\n- **Fixes:** uploads with OpenSSH work with \"[\" or \"]\" in a folder name, \"Update with a newer version…\" for Linux apps and PC VR games, and Settings shows the options most people use first.\n- **35 new working recipes.**\n- **Improvements to automatic patch detection** for games without a verified recipe.\n\nAlready have FramePort?

spoopyghosty0	9106d3f090	Agent: uninstall works with Steam library mode later/off (#305 ) cmd_shortcuts returns without "started" when it queues (later) or skips the change; cmd_uninstall indexed it and failed after the shortcut removal was already queued, leaving the game installed. Found on the Frame.	2026-10-17 16:23:27 -04:00
spoopyghosty0	39fefd225f	Steam library scheduling: now / later / off (#305 ) Installing on the Frame restarted Steam to add the shortcuts, which also closed FramePort running there. Settings -> Installing gets a Steam library mode: now (as before; restarts also wait while FramePort runs on the Frame), later (no restart: Steam's next start re-applies and verifies the shortcuts through bounded steam.service hooks) or off (no shortcuts; Play starts the game from FramePort). Restart Steam now bypasses the holds and asks before ending a running game. Agent v99. Based on the feature branch's two commits (`a311498`, `cf05ce2`), merged onto main.	2026-10-17 16:23:26 -04:00
spoopyghosty0	282f0e33c3	Showcase: keep the three renders of an unstable shot for --keep CI's monitor shot fails with "three renders, no two alike" but discarded the renders; the artifact now has unstable-<shot>-<k>.png to show what changes between them.	2026-10-17 16:22:27 -04:00
spoopyghosty0	8381dacdaa	CI: fix the tests main broke (Files icons, headset default, adapter revision) - Files: line-style icons for the drive, PC VR and Linux sections (test_ui_consistency). - test_pc_target: Quest games now also gain device.headset_model from its migration; PC VR games never do. - test_surface_projection: frame.adapter is revision 2 since the dormant foveation diagnostic (#365).	2026-10-17 16:08:26 -04:00
spoopyghosty0	fc5908618c	Files: separate sections for PC VR games and Linux apps (#361 ) Their entries open the install folder rather than Android storage, so they get their own "PC VR games" and "Linux apps" sections next to Game storage. ui_smoke: linux-files step.	2026-10-17 15:58:13 -04:00
spoopyghosty0	d7f0d51472	Foveation as a per-game setting; "Sharpness" is "Render resolution" (#365 ) Foveation (Default / Eye-tracked / Fixed / Off, radius, test) moves from Customize to Game settings → Picture. It's a user preference, not part of the recipe: existing recipes are migrated once and Share working config leaves it out. Agent v98 set_settings rewrites only the launcher's foveation exports, so a change applies at the next game start without a rebuild (checked on the Frame: Fixed adds the FDM exports, Default removes them). The APK-side parts (Batman allocation fix, Climb 2 bridge) stay in the build. The scale setting's label is now "Render resolution (supersampling)". ui_smoke: game-settings-dialog step.	2026-10-17 15:46:35 -04:00
spoopyghosty0	55c6da7010	Files: read drives through the Frame target (shared drive cache) The drive locations called the agent directly, bypassing the target that the Storage section and Move to… use and the cached app.frame_drives list.	2026-10-17 15:42:36 -04:00
spoopyghosty0	f996e5e7d9	Files: SD cards/drives and PC VR/Linux game folders as locations (#361 ) Each drive the agent reports (SD card, USB, other Steam library drives) is a Files location with its free space; read-only drives allow downloads only. Installed PC VR and Linux games get their install folder. Agent v97: drives report read_only explicitly (checked on the Frame).	2026-10-17 15:29:59 -04:00
spoopyghosty0	1e1c435191	Headset model per game, Quest 3 by default (#373 ) Games saw a Quest 2: OVRPort's dispatcher hardcodes the system name "Oculus Quest2" and a Quest 2 headset UUID (XR_META_headset_id), and OVRPlugin decides the headset type from the UUID first, then the name. device.headset_model (Customize; Quest 3 default for every Quest game, also Quest 3S, Quest Pro, Quest 2) rewrites both in the dispatcher after checking the original bytes; Quest 2 leaves the build byte-identical. FrameBridge reports the same name to games that call the runtime directly. A library migration adds the default to existing recipes (installed games show Update on Frame). Lepton's ro.product.model ("Lepton") can't be overridden by boot properties, so Build.MODEL is unchanged. Verified on the Frame: OVRPlugin logs "systemName Meta Quest 3" (was "Oculus Quest2").	2026-10-17 15:18:45 -04:00

spoopyghosty0	dd7f5d67c7	Catalog: Breachers (unsupported: needs Meta's online services) The game's own copy of Meta's platform library (libovr_custom.so) quits at start; online-only (#357).	2026-10-17 15:08:52 -04:00
spoopyghosty0	7d4e20844f	FrameBridge: XR_FB_color_space for games that require it (#336 ) OutRun Quest VR quits before its VR session with "Rec.709 color space unavailable": the Frame's runtime has no XR_FB_color_space. Adapter setting fb_color_space (off by default; triage color-space-missing suggests it) offers the extension when the runtime lacks it, reports Rec.709 and accepts any colour space without converting. OVRPort's dispatcher can't forward the new functions, so it isn't on for every game. Not yet tried on the device.	2026-10-17 14:56:59 -04:00
spoopyghosty0	fc8443fc56	Store details: refetch after Rename, reject adult Steam matches (#377 ) An import named after its code name ("Lollipop") matched an adult Steam game by exact title, and the screenshots stayed after the user renamed it. Details now record whether they were matched by package or by title; a rename (GUI, CLI, --reset) drops title-matched details and screenshots and fetches them again under the new name, keeping package-matched details and custom art. Steam matches whose content_descriptors mark sexual content are treated as no match, for details and artwork.	2026-10-17 14:36:26 -04:00
spoopyghosty0	3c43b0fb5d	Per-game language setting (device.language, #354 ) Lepton's Android is set to English (US), so games that follow the system language start in English. device.language (Customize -> Game language) sets persist.sys.locale through its own LEPTON_GFXRECON_* boot-property line, like device.hide_navbar. Verified on the Frame: the container reports de-DE and the game's VM starts with user.locale=de-DE.	2026-10-17 14:32:16 -04:00
