Resumed round: checkpoint rebuilt and re-verified (parity 3,436/3,436, walk 5,642/5,642, W1/W8 hashes 44/44, far topology 0 diffs vs CPU and WARP, far survival PASS). Remote GPU holes were missing clipped LOD skirts: tiles with visible skirt faces now fall back to the CPU mesh path, leaving only 16 far tiles GPU-rendered until a GPU skirt emitter exists. My interleaved runs (SkirtSeamVerify, process start -> whole view): CPU 1.522/1.488/1.430 s; GPU 4.271/1.749/1.659 s. A ~2.8 s first Present stall hit only my first GPU launch; Luna saw it on every fresh launch, so the trigger is still unidentified. Headless CPU clipmap 0.789 s.
