The editor commandlet can adapt the owner's copied settings/strate assets into +schema-v1 JSON, resolve it through `ResolvedWorldSnapshot::FromJson`, and reproduce the standalone +hashes at compile worker limits 1, 8, and 16.

It writes the standalone +schema scale of 25 cm per voxel. The plugin's existing Runtime generator still defines +`VOXEL_SIZE=12.5 cm`, so a Core mesh-to-`FVoxelMeshData` bridge must define the coordinate/scale +conversion before runtime use.

New profiles use strongly jittered, individually rotated elliptical rooms capped against nearest neighbors and curved cubic-Bezier passages with deterministic centerline and width variation along each edge. Room heights and feature rolls vary by cell; ledges, occasional pillars, stalactites/stalagmites, basin floors, and bounded hanging masses remain features. Point and brick detail sampling share independently rotated 96/48/24-sample bands and a smooth ridge response, preserving 12/6/3 m wavelengths at 12.5 cm per sample. The parameterized mesher evaluates the exact field through prepared 4³ bricks and the same sound skip proof in commandlet and editor-game meshing. In-editor and in-game profile changes invalidate and rebuild all loaded tiles.

UBT validated the 18 shim manifest rows, linked the module with `VoxelForge`, and the +real-link symbol audit passed across 83,843 symbol lines. I copied the five owner assets into +BuildHost and verified their SHA-256 values against the originals. + +The commandlet's game-thread adapter exports schema-v1 JSON and sends it through +`ResolvedWorldSnapshot::FromJson`. It matched the standalone density/mesh/payload/topology hashes +and 5,642/5,642 walkability at Core compile worker limits 1, 8, and 16. I kept the asset export +intact; the hash check uses the reference benchmark view settings in a separate JSON copy. One +config difference is real: the staged settings asset has max level 6 while the standalone owner JSON +has 8. Core also expects 25 cm per voxel and the plugin Runtime still says 12.5 cm, so the future +mesh bridge needs an explicit scale mapping. + +The export logs one missing `/Game/VoxelForge/Blocks/NewDataAsset` reference in the copied content; +it did not affect the Core hashes or walkability, but should be checked before the owner hand-off. + +I did not wire `AVoxelWorld` yet. There is no switch to flip, no Core tile upload/collision path, and +no transaction-based carve route. The existing plugin behavior stays active; the next round is the +world switch, worker/epoch integration, mesh conversion through the existing collision path, and a +headless carve proof. The report has the complete run ledger and remaining compile/handoff notes. + +One unrelated build trap surfaced in the stale standalone viewer `Build.ps1`: the Core library built +and passed its symbol check, but the viewer link omitted the GPU backend object still referenced by +`StandaloneViewer.cpp`.
