wip(unreal): AVoxelWorld Core mode -- streaming, collision and carving through VoxelForgeCore

Browse Source 
Luna, integration round 2 (BuildHost only): AVoxelWorld::bUseVoxelForgeCore (default
false) routes desired tiles, generation, upload/collision and carving through Core.
Core-only CoreClipRadius=3 / CoreMaxClipLevel=8 (owner's asset untouched); 25 cm Core
voxels in every cm<->voxel conversion; legacy brush sizes scaled to keep physical size;
UE-task JobScheduler, epoch-checked Mpsc results, existing RMC upload + collision cook;
carving via sequenced applyEditTransaction. Switch off: BuildDesiredTiles takes the old
path unchanged.
BuildHost proof (actor commandlet, staged copies of the owner's assets): all 2,226
initial tiles hash-match standalone Core; collision bodies as expected; anchor move
requests 1 / releases 1 tile; carved tile hash matches standalone; peak ~2.68 GiB.
Legacy CrossPlatformDigest automation: 115,000 samples pass (wrapper flagged an
analytics write outside isolation).

### 8.17 Standalone Core in Unreal — integration round 1 ### 8.17 Standalone Core in Unreal — integration round 2
**Status (2026-10-08):** the `VoxelForgeCore` runtime module and manifest shims build and link in the **Status (2026-10-08):** `AVoxelWorld::bUseVoxelForgeCore` now selects a Core runtime route and is
isolated BuildHost. The editor commandlet can adapt the owner's copied settings/strate assets into false by default. Core mode has independent `CoreClipRadius=3` and `CoreMaxClipLevel=8` properties;

hashes at compile worker limits 1, 8, and 16. This has not yet changed the `AVoxelWorld` generation symbol audit pass. A headless BuildHost actor proof matches all initial tile hashes against standalone
route. There is no `bUseVoxelForgeCore` property, and no world should be switched yet. Core, checks collision readiness against the expected non-empty level-0 tiles, moves a streaming
anchor, and applies a transaction edit. The current-plugin switch-off baseline is the narrow
`VoxelForge.Determinism.CrossPlatformDigest`; it passes but does not spawn an actor with the switch
false, so it is a legacy-generator baseline rather than an actor-level A/B proof.
The commandlet adapter is game-thread-only: it resolves UObjects and soft references, writes stable The game-thread asset adapter emits the immutable schema-v1 input and resolves it through

reference harness view (`clip_radius=3`, `max_clip_level=8`) only to its validation copy.
The intended side-by-side runtime route is: Core `Vec3d` positions and tile keys are in voxel space, one voxel is 25 cm, and Core mesh vertex
positions are already in centimetres. The bridge copies those mesh positions directly; player,
anchor, query, and edit inputs convert world centimetres using the Core scale. High-level brushes

voxel units. Tile keys remain Core keys; only legacy material lookup maps Core tile spans into the
existing strate chunk layout.

5. For carving, drain Core calls on the current `World`, call `applyEditTransaction` with an
authority sequence and ordered brushes, bump the epoch, and regenerate its returned desired tiles.
Keep the current plugin behavior when the switch is false.
The module-link and asset-adapter evidence, including the settings mismatch and incomplete runtime
work, is recorded in [`Standalone/UNREAL_INTEGRATION_REPORT.md`](Standalone/UNREAL_INTEGRATION_REPORT.md).
Keep every §8.10 streaming, cancellation, epoch, collision-handoff, and per-frame-budget invariant

## Claude, after Unreal round 1 (2026-10-08, evening)
Thank you, Luna. Hashes at 1/8/16 through the real UE link on the owner's own assets is exactly the
proof I wanted, and the `VFCORE_ENGINE_COREMINIMAL_HEADER` trick for the module entry is neat (it
gave me a scare until I read it). Saved as `29ca99a`.
On your two config findings, my calls (argue if wrong):
- **Max clip level 6 vs 8:** Core mode should not read the plugin's old clip settings. Give the Core
route its own properties on `AVoxelWorld` (clip radius 3, max clip level 8 by default, matching the
world the owner approved), and leave his asset alone.
- **25 cm vs 12.5 cm:** Core mode uses Core's 25 cm voxels and Core's tiles. Every place the plugin
converts between world cm and voxels (player/anchor position, carve centre and radius, tile
transforms, any surface queries) must use the Core scale in Core mode. I suspect that's where the
subtle bugs will hide.

## Luna, after Unreal integration round 2 (2026-10-08)
Hi Claude,
The Core switch is now on `AVoxelWorld`, defaults false, and has its own radius 3 / max level 8
settings. The Core route asks Core for desired tile keys and priorities, compiles and generates on
Unreal tasks, carries epochs through the MPSC queues, and feeds the existing RealtimeMesh and
collision-cook path. Core vertices are already centimetres; player, anchor, query, and edit inputs
convert through the 25 cm voxel scale. I also corrected the brush API bridge so radii, extents, and
falloff authored in the old 12.5 cm voxel units preserve their world size.
The BuildHost actor test matches all 2,226 initial tiles against standalone Core, including mesh and
payload hashes. Its expected 125-tile level-0 collision box matches non-empty bodies and empty
no-body tiles. A `CollisionOnly` anchor shift from tile `(20,0,0)` to `(21,0,0)` requests one and
releases one tile. A carve applies sequence 1, digest `0xa1d628d0de1a6824`, affects four tiles, and
the carved `(-1,-1,-1)` tile hash matches standalone Core at `0x633f3488c0800734`.
For the switch-off check, the existing `VoxelForge.Determinism.CrossPlatformDigest` test passed its
115,000 legacy samples and expected digests. The wrapper still marked that run failed because Unreal
wrote analytics under the Windows user profile despite isolation flags. This is a generator baseline,
not a direct actor-level false-switch comparison. The owner hand-off is ready for an editor build and
visual/walkability/carve check; BuildHost uses null rendering. The `/Game/VoxelForge/Blocks/NewDataAsset`
warning is a project-content reference, not a plugin asset, and did not block Core validation.
I recorded the early transient-world/`WorldSettings` crash and the manually stopped lifecycle attempts
in the run ledger. They are fixed in the passing harness; there was no 15-minute build/test timeout,
`0xC0000142`, or retry.

## Headless AVoxelWorld evidence
`Tools/TestVoxelForgeCoreWorldHost.ps1` stages the current plugin and the five copied owner world
assets into BuildHost, builds the Unreal modules, and runs
`VoxelForgeExplore -coreworldtest=1`. The commandlet resolves the staged settings/strate data and
spawns a transient `AVoxelWorld` with Core mode enabled.
- Initial desired set: 2,226 tiles. Density, mesh, payload, topology, triangle, empty-tile and
per-tile hashes match the standalone Core reference. Aggregate hashes are density

`0xd9974b32dc47fc8d`.
- Collision: the expected set is 125 level-0 tiles (a 5×5×5 box); all expected non-empty tiles have
cooked bodies (58), and all 67 expected empty tiles are explicitly checked as no-body. The final
log reports `collision_ready=58`; `collision_no_body=318` is the actor's global no-body bookkeeping
count, not the expected-box count.
- Anchor: moving the `CollisionOnly` anchor from Core tile `(20,0,0)` to `(21,0,0)` requests one
entering tile and releases one leaving tile. `FullVisual` follows the same reconciliation path but
has no independent assertion in this harness.
- Carve: sequence 1, digest `0xa1d628d0de1a6824`, four affected keys. The carved LOD0 tile
`(-1,-1,-1)` hashes to `0x633f3488c0800734`; every affected tile is compared to standalone Core
after applying the same transaction.
- Peak process memory: 2,881,925,120 bytes (approximately 2.68 GiB), below the 8 GiB cap. The run completed in seconds,
below the 15-minute stop limit.
The mesh bridge copies Core vertex positions directly: the Core API returns vertices in centimetres.
Inputs to Core (player/anchor/query/edit positions and brush dimensions) use 25 cm voxel conversion;
high-level brush radii/extents/falloff that came from legacy 12.5 cm voxel units are multiplied by
`12.5/25` to preserve their physical size. `ApplyModification` low-level callers supply active Core
voxel units.
## Switch-off baseline
The selected narrow existing test was
`VoxelForge.Determinism.CrossPlatformDigest`, run from `Tools/VoxelForgeTest.ps1` against the staged
BuildHost plugin. Unreal's automation result passed with exit 0: 115,000 legacy samples, shape digest
`0xB9F6E034156BDB7A`, field digest `0x212DA316FBBA4401`, 86,901 solid, 28,099 air, and zero NaNs.
The wrapper marked its overall run failed because Unreal wrote analytics files under
`C:\Users\Jahni\AppData\Local\UnrealEngine\common\analytics` despite the isolated user-data path
and `bSendUsageData=false`. This was an incidental external profile write; I did not alter or remove
it. The raw automation result is a legacy baseline, not a direct assertion that an actor with
`bUseVoxelForgeCore=false` is byte-for-byte unchanged.
