- 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.

- 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.

- Far repairs are source-aware (only where the sampled mesh lost a shell) and redundant radius probes
trimmed; ~175k two-triangle repair panels remain (+18 MiB over the no-shell 92.6 MiB).
- Pipelined start builds the shape world once; the 27-tile neighbourhood is ready ~0.73 s from
process start; pipelined whole view is no slower than direct.
- Far audit passes, bad-shell control still fails (16 missing / 16 holes); look audits pass; routes
5642/5642; 60 W1/W8 + direct/pipeline hash fields equal; six fixed captures pixel-identical.
Verified by me head to head (8 workers, cold, BelowNormal 0xFF00, quiet machine, two runs each):
1.40 s vs 1.80 s for the previous default.

- FarSurvivalAudit: checks every stratum top/bottom boundary (4x4 columns per far tile) and every
in-view far connector (sections <=128 voxels, 4 radial rays) against the emitted mesh. Falsified:
removing one tile's shell triangles -> 16 missing, 16 holes, exit 14. Passes at LOD6/7/8.
- Far connectors follow source radial crossings; strata patches emitted at LOD7/8. Default LOD8.
- Viewer: separate near ShapeWorld for the 27 player tiles, full world built on its own thread;
27/27 tiles hash-identical to the direct build. W1/W8 60 hash fields equal; routes 5642/5642.
Cost, measured by me head to head (8 workers, cold, BelowNormal 0xFF00): LOD8 without the shells
1.17-1.25 s, LOD8 with the shells 1.80 s; payload 92.6 -> 276.7 MiB. The shells are far too
expensive, and the pipelined benchmark whole view is 2.92 s (shape compiled twice): both to fix.

- Per-vertex biome lookup was the payload cost (~365 ms); far tiles now take the biome palette from a
per-tile grid. Same channels (palette, slope, border blend, UV) and ceiling/ground sections.
- Opt-in --max-clip-level=8: 6,498 -> 2,226 tiles, stream 0.876 -> 0.428 s, 1.451 s process wall.
Kept opt-in: six fixed views cannot prove every distant thin stratum survives.
- W1/W8 hashes equal across 11 outputs; routes 5642/5642; five captures pixel-identical, passage
382 px differ (max delta 16).
- Rejected with measurements: LOD6 empty-block proof (-21% samples, no wall gain), far supertiles
(no complete groups exist).
Remaining long pole: shape compile 0.854 s.

Takeover after the PC reset. Verified at 1 and 8 workers: density, geometry, full payload and
topology hashes equal for all nine outputs; routes 5642/5642; crater transaction 17 ms; player
neighbourhood mesh-ready 23 ms after streaming starts.
- The plugin's materials consume UV, the packed biome/slope/blend colours and the ceiling/ground
sections, so the viewer-only skips stay off by default (diagnostic only: 1.53 s without them).
- UVs staged as FVector2f (matches the game stream; -20 MB, no speed change). Far-bin reserve 24x.
- LOD6 is the long pole: 32.7 M density samples, 1.83 M vertices, ~1.1 s.

Verified before the reset (density + full mesh hashes equal at 1/8/16 workers, routes 5642/5642,
look audits green):
- merged field lookups, parallel mask merge, compact inline spatial bins, line-local relief hash
cache, lattice-specific mesher entry, fused sign+magnitude evaluation, far connectors as one
capsule each (181,836 -> 16,491 far primitives).
- crater edit (sphere+box+capsule, one transaction across LOD0/1): 15-27 ms; player 3x3x3
neighbourhood meshes ready ~18 ms after streaming starts.
NOT yet verified (in the tree, unhashed): standalone-only skips of UV/colour arrays and of the
ceiling/ground material grouping (best cold whole view 0.958 s @16 workers) and a far-bin reserve
tweak. Those skips drop data the plugin's materials may need: not a game-path win as-is.

- Removed the thin automatic room-support slabs that left floating caps (in-view detached thin
sheets 9 -> 0; the audit now also fails on isolated small components).
- Bounded 16-voxel floor/wall blend (18 rejected: it created a sub-voxel sheet), 3-voxel
strata/cave blend, C1 tunnel radius profile (0 radius/slope steps at joins).
- Surface relief: broad octave with amplitude modulation instead of uniform bumps.
- Cold, no cache: 64 m full detail 0.924 s (8 workers) / 0.715 s (16); whole view 2.016 / 1.605 s.
- 1-worker and 6-worker hashes match; 5,642/5,642 passage samples open.
Not solved: regular bands in the narrow passage shafts, a few slivers on tile boundaries, faint
wall/floor plates; close-view mean surface distance to the owner field got worse (see REPORT.md).

ClipRadius override 3 (64 m at 25 cm). Uncached full detail 20.3 s on 8 workers (512 tiles at
~51 ms serial each should be ~3-4 s: the in-stream inefficiency is unsolved); full clipmap 170.6 s.
The 1 s / 5 s targets were met only from an on-disk mesh cache (.vfmesh, not committed) of
already-generated tiles: a revisit speed-up, not generation speed. Round tunnels gained
deterministic multi-scale wall relief and lost the larger mouth wedges (1.54% of lattice signs
changed, mean 0.20 m). Hashes stable across runs and 1 vs 6 workers.

Cause found by profiling: room/SDF graph-cache churn (exact XY bounds + sample order rebuilt it
constantly). Region grouping (one LOD3 tile: 1,084 -> 229 builds), taller-tile traversal for LOD6
(36,480 -> 12,160), extent-dependent cache slots, lambdas instead of recursive std::function.
Serial ms/tile, 64 nearest tiles per level (before -> after):
L0 50.4 -> 50.6, L1 112 -> 110, L2 24 -> 22, L3 223 -> 73, L4 269 -> 134, L5 393 -> 127, L6 283 -> 145.
Hashes of all levels unchanged; parity 3,436/3,436 bit-identical.
Full clipmap, 16 workers BelowNormal: full detail 66.6 s, all 12,054 tiles 175 s. In-stream L0 tail is
high (median 83 ms, mean 198 ms, p95 669 ms) vs 51 ms serial.
Streaming: recentre keeps the intersection, generates only missing tiles nearest/finest first;
one crossing = exactly 441 new tiles in 6.1 s, no stale results.
Lighting: normals already come from the density gradient; the striping was the squared headlamp;
broad linear fill + warmer palette. Daytime CPU rule documented in Standalone/README.md.

Hashed TMap/TSet and real TInlineAllocator storage did not move level 0 (72.1 -> 74.1 s, within
noise): the slowness is elsewhere. StreamingWorld.h started (first build hit an int64/uint64
mismatch), library plan drafted (SHARED_CPP_LIBRARY_PLAN.md), before-normal captures saved.
Uncompiled/unmeasured parts: streaming. Resume by forking session 01a0fd2e-3c3b-7050-b4e9-628fdcc4d553.
