- Relief per wavelength band compared with the owner field; the 4-8 and 8-16 voxel bands were lost.
Restored within the partition-of-unity blend; max detail gradient 0.545 (limit 0.55).
- New owner-band gate: fails all six views on de14f00, passes all six now.
- W1/W8 44/44; path hash both directions; routes 5642/5642; stair-distance, ring, thin-sheet,
coarse-panel, far-survival audits pass; bad-shell control fails.
- Cold 1.127 s vs 1.108 s (within spread); nearest-tile readiness 12.20 vs 12.16 ms.
Caveats: the 143-ray GridStair normal audit is at 62.2% vs its 60% limit (was 76.9%); in the tunnel
capture the floor shows a regular dimple pattern, and the passage shaft close-up is still smooth.

- Stairs: cave, floor, strata and passage relief were effectively summed in overlaps (owner ray
~0.94 voxel of displacement); now partition-of-unity weights: -0.288 voxel there, max detail
gradient 0.323 voxel/voxel. High-detail patch scan 133 -> 0; exact midpoint edge roots kept
(removing them: 7,993 bad roots, 46 patches).
- Fins: exposed skirt triangle scan 1,776 -> 0; thin sheets 0; coarse off-surface panels 0.
- Path hash both directions equal; W1/W8 equal; routes 5642/5642; passage detail ratio 0.850;
far survival passes, bad-shell fails; 30-crossing flight: nearest tile 15.1 ms median, 124 ms max.
Caveats seen in the captures: the owner-ray wall has visibly less relief than before; the fin
before/after captures do not show the fins (evidence is the scan only). Cold StreamFullClipmap
0.758 s vs 0.741 s (+17 ms, Luna's interleaved run). Owner to judge: bin\VoxelForgeLookCheck4.exe.

Not verified as a whole. In the tree when Luna's session ended ("model at capacity"):
- fins: LOD seam skirts could hang into tunnel air; skirt triangles are now clipped against the solid
half-space and carry a per-face mask so a host can hide skirts between same-LOD neighbours.
- choppy LOD0 stairs: marching cubes' linear edge interpolation misplaced vertices where the relief
bends within one cell; edge crossings corrected with the exact field (82 patches, midpoint-edge
errors 18,818 -> 3,288); normal halo now ignores the +-4.125 fallback samples.
- an explicit unclamped Core distance query for audits.

- Core compiles exact-tile analytic slabs for entering tiles; a Z-column sampler reuses the coherent
noise context along each tile column; the viewer keeps residents and prioritises nearby tiles.
- 30-crossing straight flight: nearest tile ready 15.8 ms median / 27.6 ms max; full crossing wall
121 ms peak; worker CPU per crossing 545 ms median, 834 ms max.
- W1/W8 hashes equal; routes 5642/5642; look, passage, stair, thin-sheet, coarse-panel and far
audits pass; bad-shell control fails; path-hash audit kept.
Cold whole view, measured by me interleaved (busy machine): 1.242 s vs 1.255 s for 3b37d57, parity.
Still open from the owner (LOD0): fins along a strata seam, choppy stair facets.

From the owner's fly-through ("very impressive, in some cases slightly better than the original"):
- Streaming: Core compiles world-aligned fine-detail pages for tiles entering the view and releases
them when they leave; the viewer keeps resident tiles. One chunk crossing: 144 new tiles, 1,822
kept (was a full rebuild). A tile built as a late page hashes identically (density, mesh, payload,
topology) to the same tile from an initial build.
- LOD>=1 fins: off-surface planar connector panels are now checked against the source surface and
projected onto it; coarse audit 0 off-surface panels; far survival passes, bad-shell still fails.
- LOD0 stair patches: 2,630 sign-changing edges had one endpoint at the fixed +-4.125 fallback
(carve surfaces were excluded from distance storage); distances now completed analytically, 462
packed signs corrected; the audit now fails on any sign edge missing either endpoint (0 of 952,997).
- W1/W8 hashes equal; routes 5642/5642; look, passage and far audits pass.
Verified by me, interleaved (8 workers, cold): 1.014 s vs 1.008 s for aeeedaa, no regression.
Open: a chunk crossing still costs ~1.2 s of page compilation.

- The copied generator, mesher and Compat stand-ins compile inside vfcore::detail.
- CheckCoreSymbols.ps1 (run by Build.ps1) fails on any unqualified Unreal-style symbol in the
library: 16,255 on 557f6aa, 0 now. A UE 5.7 CoreMinimal.h + VoxelForgeCore.h smoke compile passes.
- Output identical: 11 hash rows at W1/W8, routes 5642/5642, look/passage/far audits pass,
bad-shell control fails, six captures byte-identical.
Cost, measured by me interleaved (8 workers, cold, 4 runs each, first run excluded): 0.963 s vs
0.937 s for 557f6aa, ~27 ms in shape compilation; same math, so codegen/inlining. To be found.

- Standalone/Core: public header VoxelForgeCore.h (no Unreal types), static library target,
ResolvedWorldSnapshot (from the schema-v1 JSON), World (compile, generateTile, density/sign,
point/segment solid, classifyBox), host-supplied JobScheduler (the core starts no threads),
sequenced, idempotent EditTransaction returning affected tiles per LOD.
- The viewer, benchmarks, edits and audits run on Core; StreamingWorld stays host code.
- Same as round 11: 11 hash rows at W1 and W8, routes 5642/5642, look/passage/far audits pass,
bad-shell control fails, six fixed captures byte-identical; cold W8 1.025 s vs 1.041 s reference.
- SHARED_CPP_LIBRARY_PLAN.md rewritten for a UBT module compiling the same sources via shims.
Open issue before Unreal: Core's implementation still compiles the Compat stand-ins named like
Unreal types (TArray, FVector...); inside a UE binary that is an ODR clash. Must be namespaced.
