WorldAssemblySurfaceProfileV1 on the native SurfaceWorld recipe and plan; version 0 'natural' is omitted
from serialized identity, so the owner world is unchanged. periodicHills (seeded cosine hills, plan-time
grade <= 15 deg), mirroredRelief (cap mirrors the floor by lambda, clearance checked) and flatField share
one profile function for points, lattice classification and exact cosine-extrema intervals (0 interval
misses in brute-force audits). Style-override fixtures with planned passages. Cold whole view about 1.33 s
for each profile vs 1.74 s natural SW (Clang). Owner hashes identical to L52; fast/medium/full PASS.

Measured first: 45% of FI tiles are all-air, yet FloatingIslandFieldV1 returned unknown for any box near
an island AABB (25,536 unknown boxes, 0 tile skips). Conservative ranges for island bodies, root lobes,
buttresses, connectors, surface detail and smooth-min budgets now let the shared box classifier prove FI
air/solid (216 tile skips; 28.6 M audited samples, 0 violations). The X8 path reuses its FI preflight
samples. LOD7-8 far-shell and column work is skipped outside per-tile island/connector influence bounds
(farHorizonVersion 4 -> 5). FI 16.74 -> 7.36 s (-56%), FI moving entering-tile p50 halved; SW unchanged.
Peer determinism (Clang/GCC W1/W8/W12, random cameras) PASS; fast/medium/full PASS.

Versioned capsule vein records (stable ID, resource ID, endpoints, radius, seeded irregularity) resolved
into the snapshot only when requested, placed beside the route and away from passages, landings and
landmarks (forced-passage control rejected). The bound field table gains materialAt (host + two resource
IDs + Q16 weights) behind a per-tile BVH; mesh export v2 carries per-vertex materials; a measurement-only
yield computes removed resource volume (0 on already-air space). With veins on, every density, mesh,
payload and topology hash is unchanged; demo off: owner hashes identical to L47. fast/medium/full PASS.

The demo tunnel's hard floor cap used a vertical Z - floorZ on a sloped Bezier floor, which is not a signed
distance, so marching cubes produced a staircase through the first 7 m (40-51 mm ripple, 82 mm steps). The
cap now uses the grade-normalised signed distance with a floor-adjacent bore re-application fading over the
entrance; mesh tile Z bounds include cavern bounds. New three-rail entrance audit: L46 fails, L47 passes.
verify: the cost baseline exports only build inputs into Saved/Linux/<out>/baseline-<commit> and removes it;
/tmp unchanged after a full tier. Demo off: owner hashes identical to L46. fast/medium/full PASS.

The flagged SW demo's ramp (57 carves + 107 support pillars, visibly ribbed) becomes one cubic-Bezier
sweep: closest point by 17-point seed plus 5 Newton steps, a cubic floor profile, a rounded 2.6 m bore,
and a hard floor cap applied after unions and relief that only adds support where the field is air.
Optional resolved cavern-graph records (one room, one edge) enter canonical identity only when present;
their bounds extend World::isTileShapeFree. Reachability passes (L43 control fails), headroom 2.8 m,
floor ripple 1.8 mm (L45 ramp control fails at 17.9 mm), shape limits met; demo off: owner hashes
identical to L45. fast/medium/full PASS. Research R13 (read-only): continuous SDF sweeps along curves.

Stamp vocabulary v2; the flagged SW demo opens through a side-facing portal and a bent ramp (max 14 deg,
two landings) into a 17 x 15 m chamber with a rock dais. New reachability audit: a capsule surface search
from walkable ground near the arrival mouth to the chamber floor (66 samples, 0 blocked/unsupported); the
buried L43 layout fails it. Demo off: owner hashes identical to L44. fast/medium/full PASS (Clang+GCC).

L27 added passage support columns, but World::isTileShapeFree only bounded the route and bridge, so tiles
touched by a column could be approved for early native-only generation; depending on scheduling they used
that incomplete field or the compiled one (six LOD0 tiles differed between W1 and W12 at an SW camera near
the arrival mouth). The shape-free proof now includes a conservative envelope for every possible column.
The compiled world is unchanged (the old W1 variant), so no version bump. verify tiers gain a seeded
(SplitMix64 0x4c3434) random-camera W1/W8/W12 sweep across both recipes and several clip settings; it fails
before the fix and passes after. fast/medium/full PASS; cost within noise. Research R11: suspect review.

ResolvedLayoutSnapshotV3::finalize maps each strate's generator and interface once into capability
records (FI gradient air-gap, surface/FI landing support, passage-anchor columns, SW-to-TN floor);
ApplyResolvedStrateBoundaryBand and passage composition read those instead of generator kinds. Derived
records stay out of canonical JSON, so layout identity is unchanged. Owner hashes identical to L41;
fast/medium/full PASS on clean Clang and GCC builds; cost within noise.

UVoxelStrateManager::Initialize resolves the layout width to integer micrometres before passages or
scheduling; each slot stores physical [bottom, top) bounds, transition mode/width and passage settings;
chunk indices remain a floor-based compatibility projection. The Core adapter derives interiors and L29
bands from those resolved values. verify: full-tier cost baseline is HEAD (or --baseline), tier timeout
7200 s with 1800 s per process; the source stamp now includes the plugin Source tree compiled on Linux
(it previously missed VoxelStrateManager.cpp and friends). Owner hashes identical to L37; fast, medium
and full PASS on a clean rebuild. Unreal manager/adapter edits are uncompiled on Windows.

BuildLinux.sh hashes a sorted manifest of compiled inputs into VOXELFORGE_SOURCE_STAMP, printed first by
every executable; Standalone/Tools/verify/verify.py checks it before and after each tier and records
binary/input hashes and the resolved recipe, style map and layout. Fast (163 s) runs on the canonical owner
world only and asserts FI Style 2 / SW Style 1; medium (8 min) and full (26 min) add the style matrix,
GCC, determinism and cost. Controls: stale source, mislabelled style-0 owner, all-black capture, L30/L31,
L35/L36 and the L38 step are all rejected. No geometry change; owner hashes identical to L37.
