nx_vrframe.nx -- F1106 VR-RUNTIME RUNG 1: the SOVEREIGN VR COMPOSITOR FRAME (operator 2026-08-10: "do you know how to actually build a vr hot and virtamate" -> the one honest GAP is the headset runtime; stereo already exists 4/4). This organ produces the SUBMIT-READY frame a VR compositor hands to a headset: two eye views with horizontal parallax (off-axis pinhole per eye) THROUGH the OpenXR-standard radial LENS PRE-DISTORTION (barrel warp r' = r*(1+k1*r^2+k2*r^4)), so the pincushion lens un-warps it to rectilinear -- the characteristic rounded VR frame with black corners. NEVER-BRICK BY CONSTRUCTION (Rule 26): pure compute + ONE regular-file PNG write. It touches NO device/firmware/CMOS/vBIOS namespace -- there is no code path here that can write persistent hardware state, and the gate proves the output sink is a regular knowledge/sites path, never /dev|/sys|/proc. Scene is a deterministic 3D depth test (receding checker floor + depth-sorted pillars) chosen because stereo/lens correctness is what rung 1 proves; the SUBJECT (a VaM-class figure) composes later off the certified body lane.
