- ovrplugin_shim.h: runtime on Steam Frame is SteamVR (HOST.md), not Monado;
drop the "Status: scaffold" line and the note that SetupLayer /
GetLayerTexture2 await a 128-byte desc (implemented against the 108-byte
ovrpLayerDesc); point RE-NOTES/SHIM-SCOPE at docs/research/.
- lever2-detect-skip-black-handoff.md lives in docs/research/, not analysis/.
- References to unpublished RE notes now say so instead of naming files that
are not in the repo.

- ovrp_GetTimeInSeconds: real export returning double (legacy direct-return
ABI); the autogen ovrpResult stub left d0 uninitialized and the game reads it
- seqlock writer: fence the odd-mark before the data stores (torn-pose window)
- drain the frameState ring on STOPPING/shutdown (stale displayTime + permanent
one-frame skew after every session pause)
- begin_frame FIFO bail: bound the wait (surface-teardown deadlock) and measure
the deadline on CLOCK_MONOTONIC, immune to wall-clock steps
- passthru: pthread_once takeover + acquire/release PT_FWD pointer cache
(first-use race could run the shim path mid-takeover)
- luma/dump/barcode readback disabled for non-4-byte swapchain formats
(staging buffers assumed 4 B/texel; wider fallback formats would overflow)
- vkWaitForFences: honor timeouts everywhere; never reset a pending cmd buffer
- detect_ue_queue: keep the caller's queue family/index when detection fails
- xrr_get_node_pose: g_spaceLock vs the sitting/standing appSpace recreate
(locate on a freed XrSpace)

An independent reimplementation of Meta's libOVRPlugin ABI on top of OpenXR, so
VrApi-era Meta Quest VR titles can run on non-Meta OpenXR runtimes (Monado,
Steam Frame) instead of being locked to Meta hardware. Original code only — no
Meta/Epic/Capcom binaries, headers, or assets. Includes a desktop harness that
drives the shim against Monado headless.
Scope/legal: interoperability; entitlement handling is out of scope. See README
for the legal/scope section and docs/ for the research trail and design notes.
