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.
Known: sawtooth at the tunnel wall foot (next round). Research R14: Windows/MSVC readiness review.

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.
