Near LOD0/1 (detail band, relief, root refinement, normals) now evaluated and
meshed on the GPU. 960 near tiles: zero sign/topology differences vs CPU and
WARP, vertex max 0.0049 mm (was 15 cm); far survival audit passes; CPU hashes
44/44 unchanged. Far connector-panel outlier (64.56 cm, LOD8) remains a
tessellation difference, and remote captures show missing far geometry on GPU.
Cold readiness (viewer clock, my interleaved runs): CPU 2.51/2.49/2.40 s,
GPU 5.05/2.68/2.80 s. The ~2.1 s Present stall hit only the first GPU launch.
Viewer spends ~1.13 s before shape compile starts (startup checks), which is
the gap between the 0.95 s benchmark and ~2.4 s on-screen.

- Eight-sample X batching of fine density rows, reuse of solved Z intervals in the candidate mask,
AVX2 marching-cubes cell classification. LOD0/1 density-grid time -61/-62%; interval/sign stage
140 -> 97 ms; candidate-axis allocation -18 MiB. Shape stage ~413 ms, detail band ~219 ms.
- W1/W8 hashes equal across 44 fields and equal to round 8; routes 5642/5642; look and far-survival
audits pass; bad-shell control still fails; six fixed captures pixel-identical.
Remote-view recapture pending (camera 500,0,0).
Verified by me, interleaved (8 workers, cold, BelowNormal 0xFF00, 2,226 tiles, 110.9 MiB payload):
1.012 / 0.927 / 0.926 s vs round 8 1.100 / 1.099 / 1.088 s.
