Route plan unchanged. Per tile, route segments whose bounded influence (tube + 4 m) touches the
tile write min-combined tube distance (base sweep); relief/floor/mouth shaping only in the shell

L74's passage bound omitted the 0.21 m wall relief and 0.20 m floor relief, so its whole-tile

single-mouth search with shorter lengths; logs candidate/rejection counts.
- Internal-chain passage floor/support tweaks (only with >2 strates): ripple 1-2 4.78->2.90 cm,
2-3 3.57->0.10 cm. Interfaces still 0/3 walkable (59/3/2 unsupported).
- verify.py: legacy tiers use Standalone/data/regression/owner_world_2strate_l61.json; new
four-strate stage reads its expectations from owner_world.json (currently red on interfaces).
- Unreal trace L14 vs HEAD, same assets (16-chunk FlatPlain): 12.20 vs 12.56 worker-s; no x2.

Linux UE builds failed on the Core wrapper module: the Linux-only PerModuleInline.gen.cpp saw Standalone/Compat
shadow headers instead of the engine's, and WITH_EDITOR was redefined under -Werror. Compat headers now forward
to the engine headers with include_next for generated Linux module TUs (canonical Core TUs opt into the Compat
definitions via CoreNamespacePreamble.h); CoreMinimal.h undefines WITH_EDITOR first. VoxelForgeCore.Build.cs
enables that forwarding and AVX2 on Linux only; VoxelForge.Build.cs disables Unity on Linux only. Portability:
std::int64_t consistently in VoxelContentManager.cpp; grouped &&/|| in VoxelRedefinedDensityField.cpp. Linux-only
trace fields split Core generateTile / mesh copy / RMC stream build. Standalone Clang and GCC whole-view hashes
are unchanged vs 3202193. The Unreal spawn trace is blocked by the owner's new assets (SW route sweep fails).

Per-round bisect of a176d07..3202193 (56 builds; timings inflated by concurrent UE builds) plus a clean
quiet-machine endpoint re-measure: L14 12.62 vs L61 14.65 worker-s (+16%), LOD0 3.99 vs 4.99 ms/tile. The
owner's Windows x2 is therefore mostly on the Unreal side or not like-for-like. Four-strate U2 plan: all
strates generate and are deterministic; passage 0-1 lower mouth is out of FI's band, 0/3 interfaces pass,
FI/TN/VS use legacy evaluators. R33: ranked Unreal-side suspects and Windows experiments.

Owner re-saved strates 2026-10-26: DA_Strate1 SurfaceWorld, 2 FloatingIslands,
3 TunnelNetwork, 4 VerticalShafts (default params). BuildHost copies and the
enforced SHA-256 tables updated (old U1 set kept in the report); the export
commandlet handles the four-strate plan; Standalone/data/owner_world.json
regenerated (SHA-256 F42F96AD...). One normal BuildHost gate passed (64/64
tiles) but its top-strate window produced 0 triangles, and a missing
NewDataAsset reference warns -- both to check. No measurements this round.

Windows MSVC catch-up after abyss L15-L61 (no Unreal there): 64-bit clipmap
shift (C4334), qualified VoxelForgeCore::WorldAssemblySubvoxelsPerVoxel, UHT
metadata and duplicate-signature fixes. Optional CoreGeometry section on
UVoxelStrateDefinition (native caves, lattice, profiled heightfields, named
stamps, rooms/tunnels; off/empty by default), resolved after passage planning.
VoxelForgeAssetVersion 2 converts strate height/transition/gap to metres on
load (exact, 0 m change on the owner's 5 assets; packages never saved).
Gates pass (SurfaceWorld, FloatingIslands, Core-off, M2, W1/W8/W16).
KNOWN REGRESSION vs L14 (2026-10-20, same command, same PC): full set 3.9 ->
5.37 s, worker-seconds 15.8 -> 30, LOD0 1.11 -> 1.69 s, ring 0.50 -> 0.80 s;
not yet attributed (Core L15-L61 vs Unreal side).

New verify.py sanitize tier (Clang address,undefined,float-cast-overflow; GCC address,undefined;
-fno-sanitize-recover) runs 19 cases per compiler at LOD0-8 across every generator, passages and the
crossing: 0 runtime reports; a planted signed-overflow control is caught by both. A static scan fixed
INT_MIN negation in floor division, unbounded signed LOD shifts and coordinate-times-extent overflow in
VoxelClipmapDesiredTiles.h and VoxelTypes.h (plugin and standalone), and VoxelWorld.cpp, VoxelContentManager.cpp
and VoxelDensityVolume.cpp (plugin only, uncompiled here). Supported-input output unchanged (version 211).
fast/medium/full PASS. Research R31 (self-checked): far-LOD 4-8 cut plan.

VoxelHash::Cell/Pair, legacy Cellular3D and the shared Core cellular hash added 0x7FFFFFFF to a signed
int32 before casting to uint32; overflow is undefined, so Clang and GCC placed cave passage 1 differently
(first differing sample at LOD1 tile (0,64,-512)). The bias is now done in unsigned arithmetic, in both the
standalone copy and the Unreal plugin header (Source/VoxelForge/Public/VoxelCaveMorphology.h). Native
caves, motifs and lattice now stream LOD0-8 with skirts and cross-level transitions. New verify.py
--speed-matrix runs every generator on one asserted-identical view (5 interleaved runs): motifs 1.33,
profiles 1.30-1.32, caves 1.41, natural SW 1.67, lattice 1.70, FI 4.93 s whole view. fast/medium/full PASS,
Clang/GCC peer hashes equal. Research R29 (open-edge ledge) and R30 (compiler-divergence suspects).

Core.Lattice.PrimitiveField v1, opt-in per strate (legacy Maze/VerticalShaft stay legacy): resolves the real
arrival and departure mouths first, plans a mandatory spine, then maze cells and two dead ends (9 rooms,
9 edges, stable IDs). The spine descends 20 m through four helix turns (6 m radius, 3 m clear width, 5 m
pitch, 2.6 m clearance; max grade 10.0 deg); each feature is one filleted void (0.57 m measured). Final-field
reachability passes at 883 stations; an orphaned shaft control is rejected; exact intervals (0 misses) and
a whole-surface audit with 0 flags. Whole view 1.69 s (above the 1 s target). fast/medium/full PASS.

Sampled cycle attribution of FI LOD0 field work: grid fill 83%, boundary 13%, skirts 4%; island roots,
columns and helix dominate, the column cache path is real but secondary (no thrashing). FI-only Z-inner
traversal at LOD0 (same lattice samples, exact) cuts FI whole view 5.35 -> 5.03 s and moving p50 by 12%;
global Z-inner and <=4-island culling were measured and rejected. The meshing band now includes the planned
passage support column's conservative bounds, closing a real gap where the arrival shaft meets the floor
(WorldAssemblyEvaluatorVersion 208 -> 209). fast/medium/full PASS, Clang and GCC.

Motif vocabulary v3: version-1 records keyed by (seed, strate, stable ID) with route keepouts, band
clearance and pairwise spacing. A rounded capped-cylinder monolith (r 1.4 m, 24 m tall) and a rounded-box
plinth, smooth-unioned into a flatField floor with a 0.55 m geometric rounding (measured fillets 0.73-1.17 m).
Exact radial/box interval bounds, a BVH, isTileShapeFree aware (0 brute-force misses, false-proof controls
rejected). Final-field route passes; whole-surface audit covers foot, cap and platform edges. Cold whole
view 0.524 s. Owner world unchanged. fast/medium/full PASS (Clang and GCC).

Opt-in --instrument-tile-drain records per-tile queue/dispatch/finish timelines, stage spans and counters
(proof skips, X8 lanes, GradAt/midpoint memo, skirts, FI cache stats); <2% when off. Measured: SW 13.3 and
FI 50.2 worker-s across LOD0-8, tails are work-saturated. FI sign-edge repair now computes in parallel and
publishes in sorted serial order (exact output): sign-edge 535 -> 47 ms, FI first tile 1.28 -> 0.85 s, near
ring 1.46 -> 1.04 s, whole view 6.09 -> 5.65 s. Proof block size, lane batching, SW midpoint memo and helper
cap 12 measured and left off. fast/medium/full PASS, Clang and GCC. Research R24: slab + motif generator.
