Historical Steam Frame API probes — 2026-09-24
These observations were made on one device and SteamOS build, not rerun as part of this repository's scaffold. They do not prove current availability or headset acceptance. No probe code, user audio, credentials or runtime binaries are shipped. See the design for proposed implementation and safety gates.
Environment
SteamOS 0.4.0 (VR variant), AArch64, glibc 2.39, Python 3.12.3; Gamescope 3.16.28-2. Linux ARM64 package availability is not evidence of inference speed or compatibility with this device.
Observations and limits
| Surface | Historical observation | Limit |
|---|---|---|
| OpenVR | Native VRApplication_Overlay initialization succeeded; IVROverlay_028, IVRInput_011, IVRSystem_026 and IVRApplications_008 were accepted. |
No rendered overlay, binding or autolaunch test. |
| Gamescope IME | gamescope_input_method_manager v3 advertised; v2 binding accepted and returned done(serial=1). |
Discovery is not delivered input. |
| Unicode delivery | A separate disposable X11/XIM receiver on the device accepted an exact mixed-script Unicode fixture via set_string and commit after checking focus on its owned window. |
One Xwayland receiver, not general games, native Wayland or PC-streamed targets. No Enter was sent. |
| libei | Sender connected; seat advertised KEYBOARD, not TEXT. | No bound device or delivered key test. |
| XTEST / uinput | XTEST advertised; /dev/uinput was openable by the test account. |
No injected XTEST key or virtual device. |
| Audio | PipeWire input device enumerated. | No microphone recording or model inference in this probe. |
| Portal | Existing portal introspection exposed no RemoteDesktop, InputCapture, Clipboard, ScreenCast or GlobalShortcuts interface. | Not a guarantee for future OS releases. |
The Xwayland receiver was destroyed after the test. No packages, services or Steam settings were changed. No microphone audio was recorded. This is a historical API probe, not a live availability check or install smoke test.
Implementation cautions
Gamescope's input-method protocol
is private and version-sensitive; see its implementation.
The serial is not a verified focus-generation guard; a roundtrip is not a text
consumption acknowledgement. The inspected gamescope-type example
interprets newline as Submit: do not use it as a transcript pipe.
Generic virtual-keyboard and data-control Wayland globals were not advertised
in this probe. Focus tracking and Steam keyboard coexistence need separate tests.
The proposed Redux model is pinned to revision
fad622f25f303105c20d70e201bcc477c88b620c; the weight file was
177,774,490 bytes in an earlier local inspection. ARM64 Python 3.12 wheels
appeared available, but no native model load or inference was performed on the
Frame. Runtime redistribution terms require separate review.
