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.
