Read from Walkabout Mini Golf's Unity log on the Frame: the Frame
controller profile, display refresh rate, eye gaze and performance
settings are all there; XR_KHR_convert_timespec_time is not, so VR
frame interpolation is unavailable on the Frame.

Lepton ships /vendor/etc/openxr/1/active_runtime.json and Valve's
implicit fdm_injection layer instead of a runtime broker; the statically
linked Khronos loader falls back to that file, so the app needs no
change.

The Frame's kernel reports sve, sve2 and the SVE2 extensions in its
HWCAP, on SteamOS and inside Lepton alike, unlike phones with the same
Snapdragon 8 Gen 3. The steamFrame flavour now builds with
-mcpu=cortex-x4 instead of cortex-x4+nosve.
docs/steam-frame.md records what the headset reported: 4 KB pages,
Android 11 (API 30) in a Waydroid-based Lepton, Mesa's Turnip as its
Vulkan driver, and SteamVR's native linuxarm64 OpenXR runtime on the
host, with the questions still open.

The adb commands named the device through a PowerShell variable, which
fish and bash do not read; each line now names it, and two grep lines
pull the driver and the relevant extensions out of the vkjson dump.

docs/steam-frame.md covers the steamFrame flavour: the CPU target and
why it excludes SVE, the Lepton entry activity and manifest, the Frame
controller map, the refresh rate and eye-tracked foveation, building and
installing, the device checklist (what to collect from the headset, the
log lines a first session should show, the open questions), and what a
native SteamOS build would need. OPENXR.md documents refresh_rate and
eye_tracked_foveation and the Frame controller profile; the Quest doc,
the Android README and the README point to it.
