Low in the window the shift is ~0 (borrows nearby low rock ⇒ stays air over the void); high up it reaches the far cliff (solid) ⇒ a shelf attached to the cliff, tapering out over the void with air underneath. Per-column `OverhangAmp`(=strength·slope-gate) + unit uphill dir `(DirX,DirY)` are resolved once in `ComputeSurfaceColumn` — the gradient sampled at the REACH scale (`OverhangReach`) so a point out over the void can "see" the cliff to know which way is uphill — and cached on `FSurfaceColumn`. It's genuine 3D (per-voxel structural re-eval), so it's gated hard to steep overhang columns; the union only ADDS rock (never removes), capped at `TerrainZ+OverhangHeight`, so `ClassifyTile` forces Mixed only in `(TerrainZ, TerrainZ+OverhangMargin]` (upward-only; margin = max `OverhangHeight`) — a shelf never holes a trivially-skipped tile, and only the thin cliff-edge band of air tiles is woken (NOT far-field like phase-3 spikes/holes). Overhang undersides classify as ground rock by the F17 rule (down-facing but below `TerrainZ`). Known v1 limit: applies at all LODs (Step-agnostic) — may alias far; gate to fine tiles later. Beaches at water line, high sky-cap ceiling. The cap is shapeable terrain in its own right (`ComputeSurfaceCeiling`, `Surface|Sky` params: `CeilingUndulation` broad inverted hills/valleys, `CeilingRidgeStrength` hanging ridgelines, `CeilingRoughness`+freq fine bumps, `CeilingWarp*`) — defaults (strengths 0, freq 0.04) = old flat-ish cap. (`Surface|Macro` params = the cheap precursor to biomes; `ReliefStrength=0` ⇒ old uniform terrain.) **Sky-cap vs ground is a PER-TRIANGLE surface class (F17), not a per-tile verdict**: the mesher classifies each unique vertex on the **worker** — only down-facing verts (`N.Z<-0.1`) pay a memoized `GetSurfaceHeightAt` column query; nearer `CeilSurf` ⇒ sky-cap, nearer `TerrainZ` ⇒ terrain overhang stays ground (a future SurfaceWorld cave roof — down-facing but below `TerrainZ` — also lands ground by the same rule; non-surface strates always ground). Triangles take the majority class of their 3 verts and are packed as **two contiguous index runs** (ground then cap, `FVoxelMeshData::NumCeilingTriangles`; skirts inherit their source triangle's run) → RMC **polygroups 0/1** → one **section per non-empty group** (`ApplyMeshToTile`, material slot = group index): slot 0 = strate `OverrideMaterial`/default (min-corner chunk), slot 1 = `CeilingMaterial` resolved at the tile's **TOP chunk** (mid as gap fallback, then min; fallback: ground material) — a coarse tile is 2^level chunks tall, so its min corner can sit in a lower strate/gap while the cap belongs to the strate above (this was the "far cap = ground material" residue), so the shadowless overhead rock is tinted separately instead of reading flat/bright. Shadow is **per section** via `FRealtimeMeshSectionConfig::bCastsShadow` (NOT the component `SetCastShadow` — RMC's proxy ignores the component flag; this is also why level≥2 far tiles only stopped casting once the section flag was wired): ground casts at level≤1, the cap section never casts, so the rock ceiling never shadows the terrain below it. History: v1 was a game-thread centre height-oracle (misclassified coarse far tiles → terrain material on the cap underside); v2 a whole-tile worker normal VOTE — which painted **mixed coarse tiles** (one far tile spanning terrain AND cap) entirely with the winner's material, and put sky material under terrain overhangs. The per-triangle class fixes both and is the identity channel caves/F8 will reuse. |

### 8.35 Shared Core column cache — World Assembler L7
|
||||
|
||||
L7 measured 1.34 million repeated formula evaluations on the W12 L1 view before sharing: 83.6%
|
||||
were another worker's XY, 4.0% were same-worker repeats after eviction, and 12.0% were halo/normal
|
||||
repeats. The world-owned shared second tier cut measured formula executions by 60.9% and improved
|
||||
median whole-view-ready time by 19.0%; moving 8 m and generating 144 entering tiles improved median
|
||||
wall time by 36.1%. Peak RSS rose by about 66 MiB. The cache is a bounded exact-value table rather
|
||||
than published pages; no scheduling affinity or page prefetch was needed to clear the measured
|
||||
whole-view threshold.
|
||||
|
||||
The thread-local first tier remains because it avoids shared atomics for local hits. The shared
|
||||
table has no lock on hits; only a miss takes a set-local spin lock. FloatingIslands' cache identity
|
||||
includes its island stable ID because distinct anchors can request the same XY with different
|
||||
column metrics. All W1/W12 L1 hashes, exact queries, and the seed-0 FloatingIslands fixture match
|
||||
the pre-L7 binary with Clang FP contraction off and GCC defaults. See
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux7/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux7/REPORT.md).

|

### 8.36 Route-invariant Core density — World Assembler M3 L13
|
||||
|
||||
For an unedited Core world, tile density, mesh, payload, and topology are a function of the world
|
||||
manifest/recipe, seed, and tile key. The reviewed manifest field is authoritative: SurfaceWorld uses
|
||||
its `Heightfield2D`, while FloatingIslands uses its `FloatingIslandFieldV1`. `World::densityAt` and
|
||||
tile generation read the same `FStandaloneShapeWorld` instance. A compiled analytic region page
|
||||
retains bounded spatial bins for page ownership and routing, but `SetSharedDensitySource` binds it to
|
||||
that base shape before publication; density, lattice, detail, classification, and solid queries
|
||||
delegate to the shared evaluator. This keeps exact queries, collision occupancy signs, page tiles,
|
||||
and base tiles on one field. Player edits remain explicit versioned overlays on that world state.
|
||||
|
||||
The route-binding change increments `WorldAssemblyEvaluatorVersion` from 5 to 6. Do not restore a
|
||||
page-local legacy evaluator: it disagrees with the reviewed field. Uniform-block proof audits must
|
||||
fill and check page tiles against the evaluator they actually sample. This is the shared Core path;
|
||||
the Unreal adapter and its asynchronous MPSC/Epoch flow are unchanged. See
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux13/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux13/REPORT.md).
|
||||
|
||||
### 8.37 Shared strate boundaries and FloatingIslands lower seal — World Assembler L18
|
||||
|
||||
`FStandaloneShapeWorld::GetResolvedStratumBounds` supplies one physical lower/upper-bound descriptor
|
||||
to layer ranges, far-field sample protection, and far-shell continuity for every strate. SurfaceWorld
|
||||
retains its exact `topChunkZ * 32` Core-voxel mapping and native heightfield cap. Native FloatingIslands
|
||||
takes its resolved bounds from its plan, whose chunk range is converted through the serialized
|
||||
owner/Core voxel ratio. Its version-3 field removes only the lower all-XY seal and calls the same
|
||||
`VF_ApplyUpperBoundarySeal` primitive used by the shared two-sided `VF_ApplyBoundarySeal` for its upper
|
||||
boundary. The ceiling therefore sits at that strate's own upper boundary, with the common
|
||||
`boundarySealSubvoxels` thickness; there is no FloatingIslands-specific height. The recipe range is
|
||||
un-inset to match the Unreal adapter. Versions 1 and 2 retain their serialized two-sided seals.
|
||||
SurfaceWorld's field and output hashes remain unchanged. See
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux18/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux18/REPORT.md).
|
||||
|
||||
### 8.38 Closed shared boundary ceilings and LOD sampling audit — World Assembler L19
|
||||
|
||||
`AppendStratumBoundaryCeilings` fills a candidate cell when the authoritative field is solid just
|
||||
inside that strate's configured upper boundary. It does not require the raw field to cross back to
|
||||
air above the boundary: the ceiling itself closes the strate even when the field continues solid
|
||||
through that plane. This avoids isolated holes where a coarse lattice node has no zero crossing.
|
||||
`FFarMeshColumnIndex::HasDownwardCellCoverage` still suppresses a fallback quad only after its
|
||||
interior and perimeter probes all hit the existing downward face. The L19 `farHorizonVersion` is 4
|
||||
for this shared boundary-cap change; hashes remain direct at LOD0–3 and salted at LOD4–8. No density
|
||||
query, stratum position, scale, or asynchronous route changes. The strict LOD0–8 roof and paired-edge
|
||||
audit and the matched before/after captures are in
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux19/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux19/REPORT.md).
|
||||
|
||||
### 8.39 Resolved layout snapshots and nominal strate bands — World Assembler L21 (historical)
|
||||
|
||||
`ResolvedLayoutSnapshotV1` is a separate Core-owned record built from the resolved manager slots and
|
||||
the native SurfaceWorld/FloatingIslands plans. It has a canonical JSON representation, schema version,
|
||||
and stable FNV-1a identity. Its physical intervals use half-open micrometre coordinates; recipe anchors
|
||||
retain their serialized fixed-point units. The Unreal adapter exports it beside `world_assembly`, so the
|
||||
layout digest never salts a recipe, manifest, density, or mesh hash. The standalone exporter follows
|
||||
the same builder after plan resolution. It runs once per plan request and is not read from density or
|
||||
tile-worker loops.
|
||||
|
||||
Each record separates the nominal ceiling, content, and bedrock bands. A strict layout requires that
|
||||
sequence for every strate and requires bedrock(N) to touch the next strate's ceiling(N+1). The two
|
||||
bands remain separately owned. Gradient and Interleaved interfaces may declare interpenetration only
|
||||
inside their explicit transition zone; Hard has zero effective width. The manager's `TransitionBlendChunks`
|
||||
is expressed in owner-chunk metres. L21 recorded the older Interleaved allowance as blend width plus
|
||||
warp amplitude; L29 now treats the declared blend width as the complete physical crossing allowance.
|
||||
Domain warp changes finger placement, but cannot extend overlap beyond that width. Compatibility validation reports current
|
||||
gaps, overlaps, ambiguities, inactive/missing bands, and unhonoured transitions while accepting them;
|
||||
strict validation rejects them. Core dispatches per-strate recipe fields without applying that
|
||||
parameter blend, even though the legacy manager helper implements it. Both band types default diggable,
|
||||
with protection represented explicitly.
|
||||
|
||||
Compatibility facts from L21: native SurfaceWorld plan/query bounds use 32 Core voxels (8 m) per
|
||||
dispatch chunk, while FloatingIslands converts the 32-voxel owner chunk through its 12.5/25 cm scale
|
||||
(16 Core voxels, 4 m). In the prototype where the top slot is FloatingIslands, this leaves a nominal
|
||||
60 m interval between the FI bottom (−60 m) and SurfaceWorld top (−120 m); the Core selectors fall
|
||||
through to the compiled analytic FloatingIslands fallback there. Core does not apply the manager's
|
||||
parameter blend at either recipe boundary. The FI v3 upper seal remains a ceiling inside its current
|
||||
content range, and its missing lower bedrock is recorded without changing evaluation. See
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux21/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux21/REPORT.md).
|
||||
|
||||
### 8.40 Fixed-metre strate layout units and shared boundary volumes — World Assembler L22
|
||||
|
||||
`StrateLayoutChunkSizeMeters` is one world-level setting, defaulting to **8 m**, independent of the
|
||||
legacy 32-voxel chunk and Core's 32³ storage tile. The director resolves the setting once to physical
|
||||
micrometres and Core subvoxels; every generator plan and dispatch reads that snapshot. At a 25 cm Core
|
||||
voxel, an 8 m layout chunk is 32 Core voxels (8192 1/256-voxel units); at 20 cm it is 40 Core voxels
|
||||
(10240 units). The Core tile remains 32³ voxels and is not a layout chunk.
|
||||
|
||||
The owner's FI/SW intervals are contiguous: FloatingIslands occupies [−120,+8) m and SurfaceWorld
|
||||
occupies [−632,−120) m. Each strate is ceiling → content → bedrock. Both solid, diggable boundary
|
||||
bands use its generator's existing `BoundarySealThickness` and `BaseDensity`; `InterStrateGapChunks`
|
||||
controls only spacing, and `EdgeSealThickness` remains horizontal. No new thickness parameter or hidden
|
||||
band height was added. The shared composition layer emits both volumes for every generator and the
|
||||
shared mesh path closes their visible ceiling and floor faces.
|
||||
|
||||
The snapshot is schema V2 and is consumed by bounds planning, native and legacy dispatch, solid-band
|
||||
composition, and validation. Strict validation accepts the real owner layouts, and the boundary probe
|
||||
audit agrees at all 27 sampled endpoints in both recipe modes. The owner authored Gradient transition
|
||||
is recorded as an explicit Hard fallback with zero interpenetration; Gradient and Interleaved mixing
|
||||
remain unimplemented and must not be inferred from the declared blend width. Seven validator negative
|
||||
controls continue to reject malformed bands.
|
||||
|
||||
Evidence and owner caveats are in
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux22/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux22/REPORT.md).
|
||||
|
||||
### 8.41 Director-resolved inter-strate passages and walkable landings — World Assembler L23
|
||||
|
||||
Core passage geometry is derived after the director has resolved physical strate bands and native
|
||||
route anchors. `PlanResolvedLayoutPassagesV1` joins every adjacent resolved pair. Its placement hash
|
||||
uses `(seed, upper strate, lower strate, connection, salt)`; `PassageConfig.DistanceMax` is the
|
||||
outer radius around world `(0,0)` (24 m for the owner's first interface), while `DistanceMin` is
|
||||
the inner radius used when a mouth has no route anchor. A route-bound mouth reuses the upper
|
||||
strate's departure or lower strate's arrival anchor, after checking it lies within `DistanceMax`.
|
||||
The legacy `UVoxelStrateManager::GeneratePassages` and its owner-voxel control points remain the
|
||||
legacy generator path; Core does not import the exported legacy `passages` array. The season
|
||||
manifest carries recipes and plans, and the adapter rebuilds the resolved layout and its passages
|
||||
from the current manager slots and route anchors each time it attaches the Core world.
|
||||
|
||||
`ApplyResolvedStrateComposition` composes the current generator field, applies the resolved ceiling
|
||||
and bedrock bands, then unions the passage carve and floor support. Only the hashed capsule path
|
||||
opens a band; the support strip stays below the player capsule. The lower mouth index splits the
|
||||
monotone descent from the short route-bound landing tail, whose height may vary with the route.
|
||||
Both route and passage audits sample the 0.34 m by 1.76 m capsule, support probes, and grade; the
|
||||
negative control compiles the same world without passage carving and must detect a blocked capsule.
|
||||
|
||||
The L23 shared-field change is `WorldAssemblyEvaluatorVersion=9`. It does not change the L22 bands
|
||||
or any generator's field away from a passage. The L23 report includes exact-query/hash comparisons,
|
||||
the blocked control, captures, and the Windows adapter checklist. §8.10's cache, proof, streaming,
|
||||
and async rules remain unchanged.
|
||||
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux23/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux23/REPORT.md)
|
||||
records the audit and captures.
|
||||
|
||||
### 8.42 Per-strate natural passages and the FloatingIslands anchor helix — World Assembler L24
|
||||
|
||||
`FStratePassageConfig.Style` now drives the shared Core planner for every generator. The default is
|
||||
`Worm`; Straight, Spiral and Cascading remain selectable per upper strate. Passage radius, reach,
|
||||
distance and style stay in the resolved-layout input, so equal seeds and route anchors produce equal
|
||||
paths on every peer. The passage carver adds bounded, deterministic wall relief (`0.24 m` before the
|
||||
gravity-facing attenuation) while its support tread follows the same route profile below the capsule.
|
||||
|
||||
FloatingIslands' owner config selects Spiral. A seed-derived anchor island near `(0,0)` is joined to
|
||||
bedrock by a 6 m radius rock root. The 3 m helix descends from the island mouth to the `-119.5 m`
|
||||
bedrock top inside that root, leaving at least the authored clearance around its 1.5 m bore, then
|
||||
widens into the Worm route toward the SurfaceWorld arrival. The selected anchor is ordinal 2; the
|
||||
other island ordinals and their placement hashes are unchanged. FloatingIslands recipe geometry is
|
||||
version 5 and the shared passage evaluator is version 10; the resolved-layout snapshot stays V3.
|
||||
|
||||
The passage naturalness audit rejects a horizontal run above 8 m (segments flatter than 0.5 degrees)
|
||||
or wall relief below 0.20 m peak-to-peak across at least 8 valid samples. The smooth-wall control
|
||||
has zero relief and fails; the anchored Spiral has 0 m flat run and 0.793 m measured relief. Strict
|
||||
layout controls, route binding, capsule clearance, support, grade, and the no-carve negative control
|
||||
remain required. Passage-centered interval proofs remain unknown/fallback rather than falsely
|
||||
certified. At the lower mouth, the shared layer now relies on native terrain plus the passage tread;
|
||||
it does not stamp additional flat route-anchor shelves over the cave opening. The L24 report records
|
||||
compiler/worker parity, unchanged SurfaceWorld hashes away from the route, captures and the Windows
|
||||
adapter checklist.
|
||||
|
||||
The Linux offscreen capture tool accepts `--headlamp=on` to aim brighter readable shading from the
|
||||
camera for interior views and `--clip-plane=NX,NY,NZ,D` to discard the plane's negative half-space for
|
||||
cutaway views. Both affect captures only, not generated geometry.
|
||||
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux24/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux24/REPORT.md)
|
||||
records the evidence and owner-facing caveats.
|
||||
|
||||
### 8.43 Enclosed FloatingIslands helix and native-solid passage support — World Assembler L25
|
||||
|
||||
L24's support tread was composited into the passage field without requiring native solid terrain at
|
||||
the support sample. A 6 m root could not contain the resolved helix either: the centreline reaches
|
||||
5.562 m from the anchor axis and the mouth bore is 4.5 m. With the old root radius, the tread could
|
||||
therefore read as a free-floating spiral outside the rock. This was not a unit conversion error.
|
||||
|
||||
The shared passage composer now emits route-mouth support, tread, and fallback support only where
|
||||
the pre-passage native density is solid. The open-air audit samples each support footprint at 0.25 m
|
||||
spacing and two depths, including route-mouth shelves; its L24 ungated-support control must report a
|
||||
violation. The FI anchor root is now a relief-bearing 13.25 m nominal rock column. Across five
|
||||
heights its measured radius is 12.0–13.375 m. Taking the maximum 5.562 m centreline radius and the
|
||||
full 4.5 m mouth bore at every height gives a conservative minimum wall of 1.938 m, exceeding the
|
||||
previous 1.5 m reserve. The authored mid-bore remains 3 m. The helix is selected from its route-bound
|
||||
root point and joins the lower route before the tunnel hands off through the shared SW ceiling.
|
||||
|
||||
The configured FI Spiral passes the capsule/support/grade audit with zero blocked, unsupported, or
|
||||
grade-failure samples; the L23 smooth-wall control fails naturalness and the L24 ungated-support
|
||||
control fails the open-air audit. The other style overrides also pass the open-air audit, but their
|
||||
capsule results are recorded individually in the L25 report because some overrides are not
|
||||
walkable after floating support is suppressed. Evaluator version is 12, FI geometry version is 7,
|
||||
and resolved-layout schema V3 remains unchanged. The L25 report records measurements, hashes,
|
||||
captures, style results, and the single Unreal adapter version edit.
|
||||

### 8.44 Walkable passages as tunnels in rock — World Assembler L26
|
||||
|
||||
L25 correctly stopped support from appearing in native air, but its SurfaceWorld-recipe passages
|
||||
still crossed a long open volume in the SurfaceWorld arrival strata. The segment map places that gap
|
||||
inside SurfaceWorld (about `-146` to `-497 m`), after the TunnelNetwork transition; it is not TunnelNetwork
|
||||
cave air. Both ends meet native rock. The shared Core planner now finds contiguous unsupported ranges
|
||||
from the native field sign and caches them by resolved-layout identity. It adds a deterministic,
|
||||
relief-bearing rock span only across those ranges. The span is at least 5 m wide, several metres thick,
|
||||
and joins native rock at both ends. The passage carve then opens the bore through the added density,
|
||||
leaving a grounded floor and rock walls/ceiling. SurfaceWorld away from the passage remains unchanged.
|
||||
|
||||
Native route support remains gated on pre-passage solid density. Before adding any support density, the
|
||||
composer also checks the resolved player capsule, so neighboring floor segments cannot restore rock
|
||||
inside the avatar path. This keeps all four style overrides walkable in both recipes. The bridge audit
|
||||
measures its authored density field at 256 route sections, checks the 5 m width and connected ends, and
|
||||
records a relief-bearing thickness range; the open-air audit still runs the L24 negative control.
|
||||
|
||||
The shared evaluator is version 13; FloatingIslands geometry remains version 7 and resolved-layout
|
||||
schema V3 is unchanged. These changes are in Core and the standalone audit/capture path; no Unreal
|
||||
adapter edit is required. The L26 report contains the eight-style table, hashes, captures and run history.

||||

||||

### 8.45 Tile-bounded passage evaluation — World Assembler M3 Linux L28
|
||||
|
||||
Each mesh tile scopes passage composition to the inclusive density-sample AABB, including the
|
||||
mesher's normal halo. A conservative feature AABB BVH selects route segments, columns and mouth
|
||||
support for that tile. A per-passage nearest-segment BVH bounds the long helix search; a separate
|
||||
passage-bound BVH rejects far L9 proof boxes. An unindexed native-only proof object uses a conservative
|
||||
linear fallback. No field, union order, serialized layout or recipe version changes.
|
||||
|
||||
The column's exact complex SDF is evaluated only in XY/Z feature candidates. A cheap density-aware
|
||||
radial guard remains for samples sharing the column's Z slab: a positive column distance can still
|
||||
lower positive base density, so skipping that guard needs an exact bound on the base field. This is
|
||||
the remaining SurfaceWorld cost noted in the Linux L28 report. The passage candidate lists and
|
||||
proof bounds preserve the L27 output.
|
||||
|
||||
[Linux28 report](Standalone/Research/WorldAssemblerM3/Linux28/REPORT.md)
|
||||
records counts, parity, costs and audit caveats.
|
||||
|
||||
### 8.46 Honored bedrock/ceiling transitions — World Assembler L29
|
||||
|
||||
The upper strate's `EVoxelStrateTransition` controls the shared interface between its bedrock band
|
||||
and the next strate's ceiling band in the Core composition path. `TransitionBlendChunks` is converted
|
||||
using the resolved layout chunk width (8 m by default). Hard preserves the flat interface. Gradient
|
||||
moves the shared surface with a smooth 2D hash field whose peak-to-peak range is at most one quarter
|
||||
of the declared width. Interleaved uses a seed/interface/coordinate-keyed, domain-warped 3D hash field
|
||||
to set actual overlap between the facing bands from zero to the declared width. The two faces move
|
||||
inward by half that overlap; the warp changes finger placement without increasing the crossing
|
||||
allowance. Both bands keep authored thickness, and their solid intervals touch or overlap in every
|
||||
XY column. Core does not blend unrelated generator fields.
|
||||
|
||||
Each boundary band keeps at least **two Core voxels** of solid thickness (0.5 m at the default 25 cm
|
||||
voxel size). Strict validation rejects thinner bands and declared interpenetration beyond the
|
||||
transition width. The world audit samples a 512 m square XY area, measures actual crossing depth and
|
||||
minimum band thickness, and sweeps every non-passage column through both bands at half-voxel spacing.
|
||||
Passage columns are excluded from the hole sweep. Near an interface mouth, the shared face returns to
|
||||
its nominal height inside the mouth radius plus a 1 m support margin, then fades back to the selected
|
||||
transition over 2 m so the authored landing floor remains supported. Negative controls reject a
|
||||
transition one micrometre wider than declared and a band one micrometre below the minimum. See
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux29/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux29/REPORT.md)
|
||||

|
||||
|
||||
### 8.47 Ground-bound SurfaceWorld departure routes — World Assembler M3 Linux L33
|
||||
|
||||
An intra-strate SurfaceWorld route follows the resolved terrain ground profile. Its route-point Z
|
||||
is the ground height plus the player's half-height; the route does not descend to the strate's
|
||||
bedrock boundary. Bedrock belongs to the separate inter-strate passage, which begins at the
|
||||
SurfaceWorld departure mouth on the ground and tunnels outward and down through native rock and
|
||||
the boundary into the next strate.
|
||||
|
||||
The old fixed candidate envelope used a 64 m chord and 16 m centre spacing. On the L33 upper-SW
|
||||
fixture, replaying that envelope sampled ground from −507.767 to −464.857 m; 366/648 candidate paths
|
||||
exceeded the 15° grade limit. The worst failures clustered near the outer west/northwest terrain
|
||||
shoulder (up to 79.971°) and the steep approach slopes around the origin. Candidate diagnostics
|
||||
separate grade failures from endpoints outside the bounded arrival/departure placement disks.
|
||||
The bounded search now limits its longest chord to the two mouth radii minus a 3 m clearance
|
||||
margin, checks centres every 8 m, and ranks endpoints near the route anchors. It finds a 21.5 m
|
||||
route from (−2.75, 0) to (18.75, 0), sampled on ground and accepted by the full capsule/support/
|
||||
grade audit.
|
||||
|
||||
The SurfaceWorld departure passage starts at the ground mouth with a 1.5 m portal, then smoothsteps
|
||||
to a 3.5 m rock tunnel over 9 m. Its ring is sized and oriented outward from the mouth, so the
|
||||
approach does not cut back under the walk route. The `FloatingIslands → SurfaceWorld → TunnelNetwork`
|
||||
fixture passes all four passage styles, including both interfaces, capsule clearance, support,
|
||||
grade, walkability, naturalness, open-air, column ends, long-bridge and route-binding audits.
|
||||
|
||||
`FloorProfileBlend` previously compared each curved floor profile with its straight chord and
|
||||
applied a 2-voxel limit. That is a curvature measurement, not a seam measurement. It now checks
|
||||
endpoint height and tangent continuity at 0.01 voxel and 0.001 voxel/m; the 3-voxel step and
|
||||
0.25 voxel/m tangent-step controls are both detected. SurfaceWorld owner hashes remain identical
|
||||
to L32 because the route-mouth, expanded column sizing and short-span support changes apply only
|
||||
when SurfaceWorld is the upper strate. No evaluator or recipe version changed.
|
||||
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux33/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux33/REPORT.md)
|
||||
records the four-style audits, captures, determinism, owner hashes, costs and retries.
|
||||
|
||||
### 8.48 Irregular passage-wall relief and grounded tread shoulders — World Assembler M3 L35
|
||||
|
||||
L34's owner-SW profile had a 7.438 m radius repeat with 0.0361 m (3.61 cm) amplitude; an independent
|
||||
mesh-normal scan also found a 4.750 m period at 0.02682 (1.537°). The geometry came from piecewise
|
||||
capsule joins, while broad value-noise bands added a second regular pattern. The shared carve now
|
||||
uses Catmull–Rom centerline interpolation on eligible interior segments, excluding short spans and
|
||||
terminal controls. Passage walls use deterministic, rotated 43/29/19 m relief with reduced terrain
|
||||
band contribution; other `VF_FieldSurfaceRelief` users, including grounded bridge columns, are
|
||||
unchanged. The shared evaluator is version 21.
|
||||
|
||||
The residual radius scan on owner-SW style 0 measures a 7.062 m period at 0.0109 m (1.09 cm),
|
||||
with 0.0044 m (0.44 cm) coherent amplitude. The independent L35 mesh-normal scan passes at 8 m
|
||||
and 0.02496 axial amplitude, below its 0.0255 threshold. The ripple audit samples both side-wall
|
||||
radii every 0.125 m in 32 m windows, scans 0.5–8 m periods, and rejects amplitudes of 0.035 m or
|
||||
more. Its synthetic control uses 2 m radius spheres spaced every 1.5 m; it measures 0.0599 m and
|
||||
must fail.
|
||||
|
||||
At the FI mouth, the flat apron is the shared passage support tread, not `LandingExtensionQ`, a tile
|
||||
edge or a separate support layer. The tread is required by capsule and support probes. L35 gives its
|
||||
outer entry shoulder a shallow taper and seeded grain while preserving the supported walk core and
|
||||
lower-mouth overlap width. The shallow quarter-weight support-height/radius spline keeps the tread
|
||||
continuous without moving its XY footprint.
|
||||
|
||||
Cascade routes also replace identical full-depth cosine lobes with a seeded shallow profile on each
|
||||
turn. Passage, capsule, support, open-air, bridge, binding, strict layout, capture, determinism, ring,
|
||||
and cost evidence are recorded in
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux35/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux35/REPORT.md).
|
||||
|
||||
### 8.49 Walk-floor washboard and FI mouth naturalness — World Assembler M3 L36
|
||||
|
||||
L35's exported owner-SW mid-tunnel floor measured a 7.250 m repeat at 0.02252 m amplitude; its
|
||||
upper-SW fixture arrival measured a 1.438 m repeat at 0.02482 m. Both came from segment-built,
|
||||
one-sided support treads meeting the native terrain zero crossing at per-segment joins. The floor
|
||||
probe samples the exported walk mesh along the resolved route, separately from the wall-radius scan.
|
||||
Eligible tread sections overlap by up to 2 m and all sparse route segments now use a bounded
|
||||
signed-distance slab, including SurfaceWorld-to-TunnelNetwork routes. This keeps the tread top stable
|
||||
across segment joins while capsule-clearance and native-solid gates retain walkability and open air.
|
||||
Regular tread tops remain seated 5 cm lower and ease back to 0.20 m within 20 m of a lower landing;
|
||||
seeded shoulder grain is removed, and gravity-facing relief is reduced while side-wall and ceiling
|
||||
relief remain irregular.
|
||||
|
||||
On v23, the same mesh probes measure 7.188 m / 0.00067 m (0.067 cm) on owner-SW and 6.500 m /
|
||||
0.00057 m (0.057 cm) on the upper fixture. The density audit checks five 32 m walk-floor windows at
|
||||
0.125 m spacing, rejects amplitudes of 0.015 m or more, and detects its beaded control. The FI mouth
|
||||
uses a local 2 m symmetric signed-field filter with the route protected and joins route-mouth support
|
||||
to native terrain with a 1.5 m smooth signed-distance union. Its mesh audit reduces the L35
|
||||
42.27° fade-ring jump to 27.13° and finds no detached component above the 0.0001 m² area floor; one
|
||||
8-triangle subthreshold component at 0.0000266 m² is recorded. The evaluator is version 23. Full
|
||||
recipe/style audits, route support, open-air, strict layout, legacy validators, determinism, capture and
|
||||
paired-cost results are in
|
||||
[`Standalone/Research/WorldAssemblerM3/Linux36/REPORT.md`](Standalone/Research/WorldAssemblerM3/Linux36/REPORT.md).
|
||||
|
||||
### 8.50 Immutable field binding — World Assembler M3 L40
|
||||
|
||||
`FStandaloneShapeWorld` now keeps a sorted `FBoundStratumField` table built from the resolved layout
|
||||
at world construction. Each entry owns a concrete SurfaceWorld, FloatingIslands, or legacy adapter
|
||||
in `FGeneratorFieldAdapterV1`, plus the resolved bounds and native plan pointer. The adapters share
|
||||
the immutable `densityAt(x,y,z,out)` shape, while `std::variant` keeps dispatch concrete instead of
|
||||
adding a virtual call to every density sample. FloatingIslands keeps its original fixed-point entry
|
||||
point for sample evaluation and its boundary parameter table is captured when the adapter is bound.
|
||||
|
||||
`DensityAt`, native SurfaceWorld/FloatingIslands evaluation, legacy SurfaceWorld bridging and
|
||||
`ClassifyBoxDetailed` select from the bound table. The native adapters no longer ask the manager
|
||||
which generator or plan to use per sample; box proof reuses the bound field objects. The existing
|
||||
float-to-fixed conversion order, density arithmetic and shared boundary composition remain intact.
|
||||
The manager's layout-width value is captured once for the legacy-compatible chunk-index projection.
|
||||
|
||||
The legacy adapter is still a compatibility bridge: `UVoxelGenerator::GetDensityAt` retains its
|
||||
own manager routing when invoked for legacy SurfaceWorld fields or out-of-plan fallback queries.
|
||||
Other shared-composition policy branches and passage/boundary planning remain outside this slice.
|
||||
No Unreal adapter or `VoxelWorld.cpp` change was needed, and the evaluator version is unchanged.
|
||||
L37/L39 owner hashes are the parity baseline; the L40 report records fast, medium, full and paired
|
||||
cost evidence.
|
||||
|
||||
### 8.51 Resolved metre layout authority — World Assembler M3 L41
|
||||
|
||||
`UVoxelStrateManager::Initialize` now resolves the layout in integer micrometres before passages or
|
||||
Core work are scheduled. The configured layout width is rounded once to micrometres; legacy height
|
||||
and inter-strate gap counts are multiplied by that width. Each slot stores its half-open physical
|
||||
interval `[bottom, top)`, height, transition mode/width, copied passage settings and their physical
|
||||
dimensions. The effective world seed is captured in the manager before passage generation.
|
||||
|
||||
The historical 8 m layout keeps its old placement: the first upper edge is +8 m, and each authored
|
||||
chunk of height or gap is exactly 8 m. `TopChunkZ` and `BottomChunkZ` are floor-based projections of
|
||||
the resolved interval, including mathematical floor for negative Z. Season schema v2 still validates
|
||||
its aligned top/bottom chunk values and stacked order as before, then maps those accepted projections
|
||||
to the same physical intervals. L29's facing ceiling/bedrock bands are derived from these physical
|
||||
intervals and the copied transition width, so their metre bounds retain the prior chunk-based values.
|
||||
|
||||
The Core adapter builds SurfaceWorld and FloatingIslands bounds, shared-layout bands, and resolved
|
||||
passage dimensions from the micrometre fields. FI and SW both receive the same
|
||||
`LayoutChunkWidthSubvoxels = round(layoutWidthMicrometres * 256 / coreVoxelMicrometres)`; layout
|
||||
conversion does not use the owner/Core scale. Owner/Core ratios remain in the legacy FloatingIslands
|
||||
parameter adapter for generator dimensions that are still authored in owner voxels. The manager's
|
||||
legacy passage builder converts resolved passage micrometres back to owner voxels only at its legacy
|
||||
geometry API boundary.
|
||||
|
||||
Chunk coordinates remain in `GetStrateForChunk`, `GetGeneratorTypeForChunk`, chunk-parameter queries,
|
||||
season-v2 validation, and legacy generator dispatch because those interfaces accept layout-chunk
|
||||
indices. Their values are cached projections from the physical slot bounds. World-Z queries and the
|
||||
Core snapshot use the half-open metre intervals. L40's bound Core field table remains the native
|
||||
per-sample dispatch path; this migration adds no manager lookup to it. The Unreal manager and adapter
|
||||
cannot be compiled in this Linux workspace, so their small source changes still need the Windows
|
||||
Unreal build before integration.
|
||||
|
||||
### 8.52 Resolved boundary and landing capabilities — World Assembler M3 L42
|
||||
|
||||
`ResolvedLayoutSnapshotV3::finalize` materializes runtime capability records from the immutable
|
||||
strate/interface fields before sampling begins. The upper interface records whether its Gradient FI
|
||||
bedrock air gap remains open and whether a SurfaceWorld-to-TunnelNetwork passage gets the special
|
||||
landing support profile. Per-strate passage records carry the existing SurfaceWorld landing profile,
|
||||
FloatingIslands route-support behavior, and passage-anchor column center policy. Shared boundary and
|
||||
passage composition reads these records; it no longer compares generator-kind strings.
|
||||
|
||||
The records are deterministic derivatives of `generator_kind`, `transition_mode`, and the resolved
|
||||
adjacent strate, and are omitted from canonical JSON. Those source fields remain in the hashed layout,
|
||||
so owner layout IDs and density hashes retain their L41 identity. The upper strate still controls
|
||||
Hard/Gradient/Interleaved evaluation; each strate still composes ceiling, content, then breakable
|
||||
bedrock. L29 transition samples and the passage-mouth fade arithmetic are unchanged.
|
||||
|
||||
`BindResolvedStratumFields` still tests the resolved generator kind once to bind the concrete
|
||||
SurfaceWorld, FloatingIslands, or legacy evaluator. Passage planning in `ResolvedLayoutInternal.h`
|
||||
also retains generator-specific anchor and default-mouth placement rules; those are outside the
|
||||
shared composition boundary policy. No Unreal source changed. See the L42 report for hashes, tier
|
||||
results and paired cost measurements.
|
||||
|
||||
### 8.53 Shared Core landmark SDF stamps — World Assembler M3 L43
|
||||
|
||||
`ResolvedLayoutStampV1` adds a small, version-1 SDF vocabulary to the shared resolved layout:
|
||||
carve ellipsoid, carve arch, fill pillar and fill dais. Requests and resolved records use integer
|
||||
micrometres and carry a stable ID, strate, position, conservative bounds, half extents, smooth-CSG
|
||||
width, bounded irregularity amplitude/wavelength and quarter-turn orientation. A stamp's seeded
|
||||
noise and bounded placement offsets derive from `(world seed, strate, stable ID)`; records are
|
||||
sorted by stable ID before the layout identity is finalized. If no request is made, the stamp fields
|
||||
are omitted from canonical JSON, preserving the no-stamp layout identity and density hashes.
|
||||
|
||||
Resolution retries a finite, deterministic set of candidates and rejects a record if its complete
|
||||
bound intersects a passage mouth or walk corridor, reaches a strate content face, or overlaps the
|
||||
ceiling or bedrock band. The director reports failure if no safe candidate exists. The strict-layout
|
||||
negative control forces a candidate onto a route and into a ceiling band and expects both rejections.
|
||||
|
||||
`FStandaloneShapeWorld` applies stamps after the shared resolved-strate boundary and passage
|
||||
composition. Carves use smooth maximum with the negated stamp SDF; fills use smooth minimum. Seeded
|
||||
trilinear value noise adds low-frequency relief without changing the conservative bound. The tile
|
||||
query scope builds a BVH candidate list from each tile's sample bounds. Samples in a tile outside
|
||||
every stamp box do no stamp SDF evaluation. Box classification marks stamp-intersecting boxes mixed,
|
||||
and native-only readiness refuses to skip them.
|
||||
|
||||
The `--landmark-chamber-demo` recipe flag adds an irregular ellipsoid chamber, a separate arched
|
||||
entrance and a low fill dais in the owner SurfaceWorld strate, about 31 m from the passage arrival
|
||||
mouth and off the walk route. It stays disabled by default. Active records carry vocabulary version
|
||||
1 in the layout identity, making the demo an explicit world change; no Unreal adapter was added.
|
||||
L43's report records the off/on hashes, walk and interface audits, outside-stamp timing, tier
|
||||
results, captures and any failed runs.
|
||||
|
||||
### 8.54 Opt-in native lattice field — World Assembler M3 R26 slice 1 (Linux L58)
|
||||
|
||||
`Core.Lattice.PrimitiveField` is a version-1 recipe selected only for one Maze or VerticalShafts
|
||||
strate by `--recipe=lattice --lattice-strate=N`. The legacy generator assets and their default
|
||||
dispatch stay unchanged. Planning first binds the actual incoming lower mouth and outgoing upper
|
||||
mouth from the resolved passage records, then creates arrival/exit overlap corridors, a mandatory
|
||||
four-turn helix and the maze spine; two deterministic dead ends are added after that route. The
|
||||
resolved room and edge seeds use `(world seed, strate, recipe version, stable ID)`. An audit control
|
||||
translates the helix 20 m away from both route junctions to make the shaft network orphaned.
|
||||
|
||||
The prototype helix uses a 6 m centreline radius, 3 m clear width, 5 m pitch, four turns and 2.6 m
|
||||
finished floor-to-soffit height. Its centreline descends 20 m over roughly 151 m; the inner-edge
|
||||
grade is about 10.0 degrees. The 2.4 m floor-wall smooth-max gives an isolated ideal fillet radius
|
||||
of 0.8485 m. A separate 0.4 m feature-union blend prevents adjoining ramps from erasing the tread.
|
||||
The swept-clear diameter is 15 m; the conservative padded feature envelope is about 20.6 m (the
|
||||
approved approximately 21 m site envelope).
|
||||
|
||||
The layout reuses the resolved cavern graph vocabulary. A per-strate opt-in selects the native
|
||||
negative-solid/positive-air field; canonical feature order is stable-ID order. Room/corridor bounds
|
||||
are indexed by the graph BVH and polyline segments have a nested deterministic BVH for density and
|
||||
interval queries. Box classification stays conservative, and `isTileShapeFree` refuses any tile
|
||||
that intersects the graph. The L58 pipeline audits the composed field from actual mouth to mouth
|
||||
with a 0.34 m by 1.76 m capsule, per-station support, 2.2 m clearance and a 15 degree grade limit;
|
||||
it also checks the orphan control, brute-force interval samples and the composed wall-foot fillet.
|
||||
The Linux58 report contains the measured reachability, surface, peer-determinism, timing and capture
|
||||
results; the code path is not promoted to legacy Maze/VerticalShafts generation.
|
||||
|
||||
### 8.55 Unreal CoreGeometry asset bridge and U1 asset version
|
||||
|
||||
`UVoxelStrateDefinition::CoreGeometry` is optional and defaults to recipe `None` with no stamps,
|
||||
rooms, or tunnels. The Unreal adapter preserves the established passage planner, then resolves
|
||||
authored stamps and cavern graph records, then finalizes the layout. Stable names are required and
|
||||
are scoped by strate in Core; landmarks may target a stamp, room, or tunnel by that stable name.
|
||||
Core profile heightfields are restricted to SurfaceWorld. Native caves require the TunnelNetwork or
|
||||
Underwater archetype; native lattice requires Maze or VerticalShafts. Core recipe/version fields
|
||||
enter the resolved layout identity when selected. An imported manifest cannot be mixed with a
|
||||
per-strate profiled heightfield.
|
||||
|
||||
The checked-out Core API contains stamp vocabularies V1, V2, and V3. Unreal uses V1 for the original
|
||||
stamp kinds and V3 for monolith/platform motifs, then combines and strictly validates the result.
|
||||
Research17 names V2, but the source API and motif vocabulary require V3; source was followed.
|
||||
Research27 water remains out of scope for U1.
|
||||
|
||||
The shared VoxelForge custom asset version is 2: version 1 records the tunnel-floor slope migration;
|
||||
version 2 adds load-time conversion for inter-strate gap, strate height, and transition width. The
|
||||
saved strate-layout width is used, currently 8 m. Old packages are converted in memory and marked
|
||||
dirty, but U1 does not save them. This does not yet migrate the rest of Research8's reflected
|
||||
spatial-property inventory: legacy chunk distances, owner/Core voxel lengths and frequencies,
|
||||
placement vectors, and other centimetre fields remain in their prior units. The U1 report records
|
||||
the five BuildHost asset values, hashes, and remaining work.

|

| Term | Meaning |
|
||||
|------|---------|
|
||||
| Legacy chunk | 32×32×32 voxels (`CHUNK_SIZE`). At the legacy 12.5 cm voxel size it spans 4 m; it is not the strate-layout unit or the Core tile. |
|
||||
| Strate-layout chunk | World-level `StrateLayoutChunkSizeMeters`, default 8 m, shared by all generators and independent of voxel size. `UVoxelStrateManager::Initialize` resolves it to integer micrometres; slot bounds, heights, gap and transition widths use those physical values. Core derives the common `LayoutChunkWidthSubvoxels` from that same width. At 25 cm it is 32 Core voxels; at 20 cm it is 40 Core voxels. |
|
||||
| Core tile | Internal 32×32×32 Core voxel tile. Its metre size follows the Core voxel size and stays separate from the configurable layout chunk. |
|
||||
| Chunk | 32×32×32 voxels (`CHUNK_SIZE`). Voxel = 12.5 cm (`VOXEL_SIZE`), so a chunk is 4 m. |
|
||||
| Density | Scalar field. `< 0` solid, `> 0` air, `0` = surface (`IsoLevel`). |
|
||||
| Strate | Vertical layer of the world, stacked downward. Has its own generator + params. |
|
||||
| Generator type | Archetype per strate: `TunnelNetwork`, `FlatPlain`, `CrystalChamber`, `Maze`, `SurfaceWorld`, `VerticalShafts`, `FloatingIslands`, `Underwater`. See §8. |

### 3.0 Human-scale generation contract (2026-10-01)
|
||||
`VOXEL_SIZE` is **12.5 cm** for the legacy generator. Its 32³-voxel chunks span **4 m**. The
|
||||
world-level strate-layout unit is a separate setting with an **8 m default**; a 16-chunk strate is
|
||||
therefore **128 m**, and a 64-chunk strate is **512 m**. Core still stores work in 32³-voxel tiles;
|
||||
at 25 cm those tiles happen to span 8 m, but they are not the layout unit. The gameplay capsule remains
|
||||
**0.34 m radius / 1.76 m tall** (**2.72 / 14.08 legacy voxels**). Research-field dimensions are authored
|
||||
in metres and converted at runtime. The live
|
||||
strate generator continues to read voxel-valued shape parameters from its assets, so those authored
|
||||
dimensions become half as large in metres unless their asset values are doubled. U1 adds a
|
||||
versioned in-memory conversion for strate height, transition width, and inter-strate gap only; the
|
||||
broader Research8 voxel/chunk/centimetre inventory is not yet migrated.
|
||||
`VOXEL_SIZE` is **12.5 cm**; 32³ voxels make each chunk **4 m**. The gameplay capsule remains
|
||||
**0.34 m radius / 1.76 m tall** (**2.72 / 14.08 voxels**). The default strate envelope is
|
||||
**16 chunks / 512 voxels / 64 m**; serialized owner strate assets that still say 8 chunks must be
|
||||
changed to 16. Research-field dimensions are authored in metres and converted at runtime. The live

The intended metre-scale families remain: room diameters **8-20 m**, origin hub **24 m**, room cells

||||
**32 m**, round tunnel bores **3-4 m**, maze cells **16 m** with a **6.25 m nominal bore** (**3.125 m**
|

radius; **3.0625 m** worst-case usable floor after roughness), slab open span **22.4 m**, shaft
|

diameters **4-7 m**, island diameters **12-24 m**, and ordinary inter-strate bores **3-4 m**. Source

new fixed physical dimensions are authored in metres and converted to voxel counts at the boundary.

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.

Each mouth independently queries its own strate's pure player-fit `VF_SuggestLandingPoint` with its contract seed (cave room salt, otherwise world seed), may move within its archetype-specific budget, then receives a body-sized local room/floor. The origin landing is reserved for the future shaft; no landing-to-root road is generated.

### 3.37 Unreal CoreGeometry assets and partial metre upgrade — World Assembler U1
|
||||
|
||||
`Public/VoxelStrateTypes.h` declares optional `FVoxelForgeCoreGeometry`. Its default recipe is Off
|
||||
and its stamp, room, and tunnel arrays are empty. `Private/VoxelForgeCoreAdapter.cpp` maps authored
|
||||
metres to Core layout requests after passage planning and before finalizing the layout. Stamps use
|
||||
the V1 resolver for original stamp kinds and V3 for monolith/platform motifs because the checked-out
|
||||
Core API exposes V3; authored cavern records use `ResolveResolvedCavernGraphV1`. Stable feature
|
||||
names are namespaced by strate in the resolved layout. `FStrateLandmark::CoreGeometryStableName`
|
||||
binds one landmark to such a resolved record, and `VoxelContentManager.cpp` builds its lookup from
|
||||
the finalized snapshot. `VoxelWorld.cpp` retains resolved layout identity in content hashing.
|
||||
|
||||
`Private/VoxelForgeAssetVersion.h` sets the shared custom version to 2. `UVoxelSettings::Serialize`
|
||||
and `UVoxelStrateDefinition::Serialize`/`PostLoad` upgrade only inter-strate gap, strate height,
|
||||
and transition width using the saved 8 m layout chunk. These conversions are version-guarded and
|
||||
idempotent. No package save is performed by the audit. Other Research8 chunks, owner-voxel lengths,
|
||||
Core-voxel lengths/frequencies, and centimetre fields remain on their existing units and need a
|
||||
separate migration.
|
||||
|
||||
Likely compile/UHT touchpoints are the reflected nested fields in `VoxelStrateTypes.h`, Core snapshot
|
||||
and resolver signatures in `VoxelForgeCoreAdapter.cpp`, `FCustomVersionRegistration` and the old
|
||||
tunnel-slope version in `VoxelStrateDefinition.cpp`, plus the standalone `VoxelForgeExplore` audit
|
||||
in `VoxelForgeExploreCommandlet.cpp`. `GetStrateForChunk` still receives layout-chunk Z, not a Core
|
||||
tile index. See `Standalone/Research/WorldAssemblerM3/Unreal1/REPORT.md` for BuildHost evidence.

# VoxelForge strata, units, and generation layers
|
||||
|
||||
**Design round L20 — 2026-10-20**
|
||||
|
||||
## Summary
|
||||
|
||||
Author strate layout in metres and give each strate a voxel size. Keep Core's internal tile at 32³
|
||||
voxels; its physical width follows that strate's voxel size and the tile's LOD. Use one director to
|
||||
resolve the season, layout, seed, generator recipe, resolution, and interfaces before workers start.
|
||||
Generators then evaluate an immutable, common field contract. A shared composition layer applies
|
||||
strata boundaries, gaps, seals, edits, caches, and proofs. The mesher consumes that composed field
|
||||
and generic surface hints; it should not branch on SurfaceWorld, FloatingIslands, or feature type IDs.
|
||||
|
||||
The code already has parts of this shape, but not the boundaries between them. In particular,
|
||||
`FStandaloneShapeWorld` is both a dispatch layer and a collection of field adapters, while
|
||||
`World::generateTile` contains generator-aware far-surface and feature refinement. The Unreal
|
||||
adapter currently translates two different meanings of “chunk” into Core coordinates.
|
||||
|
||||
The L19 ledges are not explained by a different density recipe per LOD. The ring audit found
|
||||
upward-facing terrain from the same lower SurfaceWorld field at different extracted heights on
|
||||
adjacent LODs. At the default 25 cm Core voxel size, LOD1, LOD2, and LOD3 sample at 0.5 m, 1 m,
|
||||
and 2 m. The maximum LOD1→2 ring difference is 1.49862 m; LOD2→3 reaches 7.73318 m, with 8
|
||||
no-hit samples among 308. An explicit shared surface contract can give all LODs common boundary
|
||||
geometry and a controlled transition band. A planar ceiling alone will not fix these ground ledges.
|
||||
|
||||
One conversion issue needs an explicit preservation target. The current Core path maps one
|
||||
SurfaceWorld slot chunk to 32 Core voxels (8 m at 25 cm), but one FloatingIslands slot chunk to
|
||||
32 owner voxels at 12.5 cm (4 m). Converting each current interpretation independently into metres
|
||||
can preserve each field's current positions, but it does not make shared chunk indices one common
|
||||
physical boundary. The converter must record the actual per-strate bounds and any resulting gap or
|
||||
overlap before choosing a unified interface. Do not promise a no-movement migration from a single
|
||||
global “metres per chunk” constant.
|
||||
|
||||
Metres are not a runtime cost concern. Resolution is. Halving voxel spacing in all three axes means
|
||||
about eight times as many density samples for the same physical volume, plus more tiles, queue work,
|
||||
and cache entries because each internal tile remains 32³ voxels. With 25 cm as the default for all
|
||||
strates, the proposed starting resolution matches today's Core sampling resolution.
|
||||
|
||||
## 1. Current code mapped to the three layers
|
||||
|
||||
There is no single class called “director” today. The director work is split between Unreal's
|
||||
season/layout code, the Core adapter, and Core's tile scheduler.
|
||||
|
||||
| Intended layer | Current location and symbols | Current responsibility and boundary issue |
|
||||
|---|---|---|
|
||||
| **Director / orchestrator** | `VoxelStrateComposer.cpp`; `VoxelSeasonManifest.cpp`; `VoxelStrateManager.cpp` (`Initialize`, `GetGeneratorTypeForChunk`, `GetGenerationParams`); `VoxelWorld.cpp` (`BuildDesiredTiles`, tile scheduling, epochs); `VoxelForgeCoreAdapter.cpp` (`BuildSurfaceStratumPlan`, `BuildFloatingIslandStratumPlan`, `AttachValidatedWorldAssembly`) | Composes season params and stacked slots, resolves generator kind and seed, and serializes the Core snapshot. `WorldAssemblyManifest`, `WorldAssemblyPlanV1`, and their `FromJson`/`finalize`/`validate` functions in `WorldAssemblerInternal.h` are the current plan/manifest format. Resolution and bounds are not fully resolved here: Core re-derives them using generator-specific conversions. `TopWorldZ`, `BottomWorldZ`, `HeightInChunks`, and `InterStrateGapChunks` remain chunk/voxel-coordinate based in owner-facing data. |
|
||||
| **Generators** | SurfaceWorld: `Heightfield2D` in `VoxelForgeCore.h` and `WorldAssemblerInternal.h`; plan construction in `VoxelForgeCoreAdapter.cpp`. FloatingIslands: `FloatingIslandFieldV1` in `VoxelForgeCore.h` and `FloatingIslandsInternal.h`; plan construction in the adapter. Legacy: `UVoxelGenerator::GetDensityAt` in `VoxelGenerator.cpp`, `VoxelDensityOpStack.cpp`, and `VoxelCaveMorphology.cpp`. | SurfaceWorld and FloatingIslands have distinct plan and evaluator APIs. Legacy generation still asks the manager for the current chunk's params and generator type. In Core, the “generator” boundary is obscured by `FStandaloneShapeWorld`, which selects native fields or falls back to the copied owner generator. |
|
||||
| **Shared field / composition library** | Noise and fixed-point evaluation: `WorldAssemblerInternal.h`, `FloatingIslandsInternal.h`. CPU/HLSL far-field math: `VoxelForgeFieldShared.h`. FP contract: `CoreNamespacePreamble.h`. Feature culling and caches: `BuildWorldAssemblyFeatureTileListV1`, `ScopedWorldAssemblyFeatureQueriesV1`, `SharedColumnCache.h`, `ThreadLocalStorage.h`. Field bounds/proofs: `Heightfield2D::interval`, FloatingIslands bounds, `FStandaloneShapeWorld::ClassifyBoxDetailed` and `BuildShapeDependencyProof`. Density seals: `VoxelDensityPrimitives.h`. | Useful shared pieces exist, but only for subsets of recipes. Noise is not one library used by every legacy and native generator. Bounds, density, and output identity still use subvoxels of a Core voxel. The canonical stratum bounds descriptor `FResolvedStratumBounds` is private to `ShapeWorldInternal.h`, not part of the plan contract. `AppendStratumBoundaryCeilings` is under far-shell/meshing code, even though the boundary meaning is shared composition policy. |
|
||||
| **Mesher** | `UVoxelMarchingCubesMesher::GenerateMesh` in `VoxelMarchingCubesMesher.cpp`; dispatch and mesh assembly in `World::generateTile` in `VoxelForgeCore.cpp`; `FarShellsInternal.h`; hybrid sharp support in `VoxelHybridSharpMesher.h` and `VoxelMarchingCubesMesher.cpp`. | MC, skirts, far shells, connector repair panels, LOD refinement, and cap repair are spread across the production mesher and Core tile builder. `World::generateTile` scans recipe feature type IDs, refines type-4 shelves only at LOD0–2, selects a native SurfaceWorld horizon, and invokes separate ground/cap repair. `FStandaloneShapeWorld::BuildFarFieldTileInput` constructs FloatingIslands connector panels. These are recipe-aware mesh paths. |
|
||||
|
||||
### What crosses a boundary today that should not
|
||||
|
||||
- `FStandaloneShapeWorld` reads `UVoxelStrateManager`, `FStrateSlot`, `WorldAssemblyManifest`, legacy
|
||||
generator params, and generator type. It selects a recipe, evaluates a field, resolves its bounds,
|
||||
applies a seal, and builds GPU far-field input. That combines director, generator adapter, shared
|
||||
field, and renderer responsibilities.
|
||||
- `World::generateTile` knows `WorldAssemblyPlanV1`, SurfaceWorld heightfields, feature numeric IDs,
|
||||
and FloatingIslands presence. The generic mesher should receive capabilities and surface data,
|
||||
not know those recipe identities.
|
||||
- The adapter exports one layout but encodes physical positions in `WorldAssemblySubvoxelsPerVoxel`.
|
||||
That makes a physical length's fixed integer depend on the selected Core voxel size.
|
||||
- Core `WorldAssemblyStratumPlanV1` carries `topChunkZ`/`bottomChunkZ`; validation in
|
||||
`WorldAssemblerInternal.h` multiplies those values by `32`. FloatingIslands additionally stores
|
||||
its own owner-to-Core size ratio and metric-equivalent bounds in Core-voxel units.
|
||||
- The Core boundary path calls `GetResolvedStratumBounds` differently for SurfaceWorld and
|
||||
FloatingIslands. The director should resolve a single physical boundary record once.
|
||||
- Legacy density still reaches into manager-owned params and operations. It must become a generator
|
||||
adapter that consumes the same resolved request as a native recipe, or remain explicitly marked as
|
||||
a compatibility route until it can be ported.
|
||||
|
||||
## 2. Violations, ranked by risk
|
||||
|
||||
Rank 1 is the highest risk to correct physical layout and cross-LOD output.
|
||||
|
||||
| Rank | Risk | Violation and evidence | Why it matters |
|
||||
|---:|---|---|---|
|
||||
| 1 | **Critical** | **No single physical bounds/interface contract.** `FResolvedStratumBounds` in `ShapeWorldInternal.h` derives SurfaceWorld bounds from `Slot.*ChunkZ × 32`, but derives native FloatingIslands bounds from `layout*ZSubvoxels` and an owner/Core scale ratio. `GetResolvedStratumBounds` is then reused by field classification, far-field protection, and far ceiling generation. | A shared logical slot boundary can map to different metre positions depending on generator. This can make an apparent seam a gap, overlap, or misplaced terrain surface before the mesher samples it. It also makes “preserve the old heights” ambiguous unless the old per-field physical bounds are recorded. |
|
||||
| 2 | **Critical** | **LOD extraction has no required shared surface representation.** `World::generateTile` uses normal MC sampling for LOD1–3; native SurfaceWorld ground refinement is only invoked at LOD4+. L19's strict ring probe excludes skirts and masked triangles and measured 149.862 cm max at LOD1→2 and 773.318 cm max at LOD2→3. | A coordinate-stable density function does not guarantee equal extracted surfaces when sample grids differ. Thin seals can be skipped, and a heightfield root can shift with coarse XY/Z samples. This is the measured ledge failure. |
|
||||
| 3 | **High** | **Chunk, owner-voxel, Core-voxel, and fixed-point units are mixed.** `WorldAssemblyFixed` in the Unreal adapter serializes lengths as 1/256 Core voxel. SurfaceWorld plan bounds use `Slot.BottomChunkZ * 32` and `(TopChunkZ-BottomChunkZ+1)*32`. FloatingIslands uses `32 × ownerToCoreScaleNumerator / denominator`. `ShapeWorldInternal.h` reverses Core Z to legacy chunk coordinates with `/ GetCoreVoxelsPerOwnerChunk()`. | A parameter's physical interpretation depends on generator and runtime Core size. `/32`, `*32`, and scale-ratio logic are reasonable only in a single boundary adapter or for the internal fixed tile; they are incorrect as the authored layout contract. |
|
||||
| 4 | **High** | **The Unreal adapter and manager both resolve the same layout.** `VoxelStrateManager.cpp` creates chunk slots and per-generator runtime params; `VoxelForgeCoreAdapter.cpp` re-reads those params and builds distinct native plans; `ShapeWorldInternal.h` maps Core samples back through the manager again. `WorldAssemblyStratumPlanV1::topChunkZ/bottomChunkZ` are checked against the manager in `AttachValidatedWorldAssembly`. | The runtime can validate matching integer slots without validating that the resulting physical bounds mean the same thing for both generators. The future adapter should serialize already-resolved metres and per-strate resolution. |
|
||||
| 5 | **High** | **Generators read director state.** Legacy `UVoxelGenerator::GetDensityAt` asks the manager for type/params and builds/refetches operator stacks. Core native lookup also asks the manager which generator applies at a Core sample. | The generator cannot be a pure evaluator of a resolved recipe. It is hard to cache, audit, or replay independently, and unit conversion is repeated in worker code. |
|
||||
| 6 | **High** | **Boundary behavior is split between recipe and shared paths.** FloatingIslands geometry v3 special-cases top seal evaluation in `NativeFloatingIslandDensityAt`; older geometry versions retain two-sided seals. `VF_ApplyBoundarySeal`/`VF_ApplyUpperBoundarySeal` provide shared density math, while `AppendStratumBoundaryCeilings` separately patches missing mesh coverage. SurfaceWorld also owns a heightfield cap. | Density closure, boundary ownership, and visible cap geometry can disagree. A shared operator alone does not guarantee a shared, LOD-stable surface. Preserve versioned historical fields during migration, then route new plans through one contract. |
|
||||
| 7 | **Medium-high** | **Mesher contains recipe policy.** `World::generateTile` has SurfaceWorld native-horizon selection, a SurfaceWorld-only far skip condition, type-2 sharp boxes, type-4 shelf refinement, separate native ground/cap refinement, and a `farHorizonVersion` identity. `ShapeWorldInternal.h` creates connector panel repairs from FloatingIslands. | A new recipe requires mesher edits and generator details leak into extraction. The mesher should consume explicit surfaces, generic feature constraints, and a requested error/refinement hint. |
|
||||
| 8 | **Medium-high** | **Legacy paths do not share the new generator format.** `UVoxelGenerator`, operator stacks, morphology caches, Core's native `Heightfield2D`, and `FloatingIslandFieldV1` have separate recipe/parameter routes. | “One generator format” is not yet true. A migration wrapper is needed so behavior can be ported in small, hash-checked steps instead of reimplementing all legacy archetypes at once. |
|
||||
| 9 | **Medium** | **Shared helpers and numeric policies are partial.** Core's FP preamble/self-test applies to Core translation units; fixed-point noise is implemented in assembler code, island noise is in a separate implementation, and far CPU/HLSL math has its own shared header. Feature bounds/caches are more reusable than the field interfaces. | Keep the tested Core determinism contract, but promote the shared numeric/noise primitives only where their exact semantics can be versioned. “Shared” code is not automatically cross-platform identical if separate float evaluators remain. |
|
||||
|
||||
### Unit measurements relevant to migration
|
||||
|
||||
`CHUNK_SIZE` is 32 and `VOXEL_SIZE` is 12.5 cm, so the owner's legacy chunk is 4 m
|
||||
([`VoxelTypes.h`](../Source/VoxelForge/Public/VoxelTypes.h), [`Round5`](Research/WorldAssemblerM3/Round5/REPORT.md)). The current default Core voxel is 25 cm. In the current native Core routes:
|
||||
|
||||
| Route | Current conversion | Physical chunk width at default | Evidence |
|
||||
|---|---|---:|---|
|
||||
| SurfaceWorld | `32` Core voxels per slot chunk | 8 m | `BuildSurfaceStratumPlan` uses chunk bounds directly in Core voxel units; L18 records the preserved `topChunkZ × 32` mapping. |
|
||||
| FloatingIslands | `32 × 125000/250000 = 16` Core voxels per owner chunk | 4 m | `BuildFloatingIslandStratumPlan` serializes the ratio and applies it to layout bounds; `GetCoreVoxelsPerOwnerChunk` uses the same ratio. |
|
||||
|
||||
This confirms the claimed factor of two. It does **not** prove that this conversion alone caused
|
||||
the L19 ring delta. L19 isolated the observed step to coarse extraction of lower SurfaceWorld
|
||||
terrain, and the reported LOD4+ horizon refiner cannot affect those LOD1→2 and LOD2→3 values.
|
||||
|
||||
## 3. Generator contract and one-time interface handling
|
||||
|
||||
### What the director resolves before generation
|
||||
|
||||
The director should publish an immutable `ResolvedWorld` (exact type/schema is an implementation
|
||||
choice) containing:
|
||||
|
||||
- a stable world/season identity and seed;
|
||||
- an ordered list of strates with a stable ID, generator kind and recipe version;
|
||||
- each strate's physical minimum and maximum bounds in metres, including height as their difference;
|
||||
- a voxel size in metres per strate (25 cm default for every strate);
|
||||
- route points, island anchors/connectors, and all top/bottom/ceiling positions in the same physical
|
||||
coordinate space;
|
||||
- one resolved interface record per adjacent pair, including any explicit void, bedrock gap,
|
||||
sealed contact, upper cap, passage, or open boundary;
|
||||
- any season-level values that affect world output, such as routes, islands, water datum, or biome
|
||||
selection, already attached to their owning strate or interface;
|
||||
- a canonical identity over the sorted resolved layout, seed, resolution map, recipes, and interface
|
||||
records.
|
||||
|
||||
Do not make generators ask the director for the active `FStrateSlot`, chunk number, season, or
|
||||
neighbour generator while evaluating a point.
|
||||
|
||||
### Request to every generator
|
||||
|
||||
A worker request should give the generator:
|
||||
|
||||
1. The immutable resolved recipe and stable stratum ID.
|
||||
2. Physical query/tile bounds in metres, including the exact halo requested by the mesher.
|
||||
3. The canonical sample coordinates or a clearly defined lattice origin and step. Voxel coordinates
|
||||
are useful as an internal derived lattice, but metres/physical fixed units are the identity space.
|
||||
4. The resolved per-strate voxel size and seed. LOD can be included as a sampling hint; the canonical
|
||||
field value itself must not change just because the caller chose another LOD.
|
||||
5. Read-only interface descriptors that touch the request bounds. Pass boundary records, not a
|
||||
pointer back to the neighbour's manager or mutable generator.
|
||||
|
||||
### Result from every generator
|
||||
|
||||
The common result should provide a deterministic field evaluator and its declared capabilities:
|
||||
|
||||
- signed density using one documented solid/air sign convention;
|
||||
- optional material or surface-class data;
|
||||
- conservative interval/classification proofs and conservative feature/influence bounds, or an
|
||||
explicit “unknown, evaluate” result;
|
||||
- optional semantic 2D surfaces such as a ground heightfield or a cap, in physical coordinates;
|
||||
- a detail envelope / maximum safe sample spacing hint. It is a hint to generic LOD/refinement
|
||||
policy, not permission for a recipe to choose its own mesh path;
|
||||
- generator/schema/evaluator versions for stable plan and output identity.
|
||||
|
||||
Keep the established fail-open behavior: an unknown interval or influence bound causes evaluation,
|
||||
not a solid/air skip. Existing feature candidate lists and worker caches fit this contract as
|
||||
optimizations beneath the evaluator.
|
||||
|
||||
### Interfaces, seals, caps, and voids belong to shared composition
|
||||
|
||||
The director resolves the meaning and exact physical location of each interface once. The shared
|
||||
composition layer then combines generator fields and applies boundary semantics in a fixed order:
|
||||
|
||||
1. Evaluate each generator only for its declared physical domain, retaining its ordinary
|
||||
field/feature behavior.
|
||||
2. Apply the interface contract once: for example, a physically measured seal band, a cap surface,
|
||||
open void, bedrock gap, or permitted passage. The contract declares ownership, sidedness, material
|
||||
class, collision/support policy, and whether player edits may cut it. A gap is data, not an
|
||||
accidental “no generator found” branch.
|
||||
3. Apply world edits through the canonical composed field, so both sides see the same edit in
|
||||
physical space.
|
||||
4. Give the resulting field, proofs, and any explicit surfaces to the mesher.
|
||||
|
||||
This centralizes the semantics currently spread across generator density wrappers,
|
||||
`FResolvedStratumBounds`, and `AppendStratumBoundaryCeilings`. Existing versioned manifests still
|
||||
need compatibility adapters: do not silently reinterpret old `boundarySealSubvoxels` values.
|
||||
|
||||
For two different generator kinds that meet at a plane, both should reference the same stable
|
||||
interface ID and exact physical boundary. Their density fields can remain independent; shared
|
||||
composition owns the boundary rule. If the plan intentionally has open space between them, the
|
||||
resolved layout records that metre-valued interval explicitly.
|
||||
|
||||
## 4. Why LOD changes thin features, and the interface surface contract
|
||||
|
||||
MC samples density at lattice corners. A thin seal or cap can be narrower than one coarse cell, so
|
||||
the coarse grid may see no sign change at all. If it does see a crossing, interpolation uses the
|
||||
coarse cell's endpoint values; its root can differ from the finer grid's root. A shared analytic
|
||||
density function guarantees the same values at the same physical coordinates, not the same triangles
|
||||
from different sample grids.
|
||||
|
||||
For a physical strate boundary, use an explicit surface descriptor with exact height/shape in metres
|
||||
and a globally stable sample phase. Every LOD must use common anchors along tile and LOD transition
|
||||
edges. The mesher can fill the interior at its chosen rate, then build a deterministic transition
|
||||
band from those common anchors into its coarser interior. A seal/cap should not rely on a sub-cell
|
||||
thin density strip surviving arbitrary MC sampling.
|
||||
|
||||
For the L19 lower-ground ledge, the same rule needs a SurfaceWorld ground profile available to the
|
||||
mesher as semantic surface data. A shared planar boundary cap would only close the strate ceiling;
|
||||
it would not align these upward-facing ground triangles. The surface can be band-limited by LOD, but
|
||||
the adjacent LODs must share their transition samples and be checked against a physical error
|
||||
tolerance. If that cannot be met with a transition band, refine only the affected boundary tiles.
|
||||
|
||||
The costs are extra boundary vertices/triangles and some CPU work to construct common transition
|
||||
strips. Collision/support must consume the same interface representation where that surface is
|
||||
collision-relevant. The owner would see caps and ledges hold one physical height as the camera moves
|
||||
between LODs, instead of steps or holes appearing at the ring. Authoring remains in metres; internal
|
||||
tile and transition details stay hidden.
|
||||
|
||||
This is not free geometry, but it is bounded to boundaries and LOD transition bands. L19 has already
|
||||
shown why “add a thin density seal and sample it normally” is not a sufficient all-LOD guarantee.
|
||||
|
||||
## 5. Keep the per-strate resolution door open
|
||||
|
||||
Yes. A 25 cm per-strate default preserves the current Core sample spacing, and the common physical
|
||||
field coordinate contract leaves room for later different sizes. Do not enable mixed resolutions
|
||||
until the Round5 boundary contract is met:
|
||||
|
||||
1. Canonical physical-space field queries and explicit ownership at a shared boundary.
|
||||
2. Deterministic transition meshes with common LOD ancestry on both resolutions.
|
||||
3. Physical-space edit rasterization/replay that reaches both grids exactly once, with no holes or
|
||||
double application.
|
||||
4. A stable, canonically sorted strate-ID-to-size map included in plan/season identity and border
|
||||
hashes.
|
||||
5. Streaming and collision rules for tiles that touch or span two resolutions.
|
||||
|
||||
At today's one-size setting, the size map has one value (250,000 microns) for every strate. It adds
|
||||
no mixed-resolution mesh, edit, or streaming cost. Tile width remains `32 × voxel size × 2^LOD`;
|
||||
different future sizes change physical tile width and workload, but never change the 32³ internal
|
||||
tile format.
|
||||
|
||||
## 6. Migration plan with “worlds don't move” checks
|
||||
|
||||
The checkpoints distinguish expected equality from a deliberately changed interface mesh. A plan
|
||||
or schema identity can change even when field output remains equal; record both identities and mesh
|
||||
hashes separately.
|
||||
|
||||
| Step | Work | Expected equality / check | Changes output? / Unreal PC? |
|
||||
|---:|---|---|---|
|
||||
| 0 | Freeze the L19 evidence as the baseline: W12, Clang with FP contraction off; retain the whole-view hashes, full-detail hashes, strict ceiling audit, captures, and FI/SW ring tables. | Baseline hashes recorded below; pin the protected SW LOD0–2 hashes too. Capture byte/pixel comparisons and ring samples must retain location, LOD, and skirt exclusion. | No. No new build needed for this design round. |
|
||||
| 1 | Add a versioned resolved-metre layout representation and a read-only conversion/audit path. The audit reports, per strate, old input units, resolved old physical bounds, new metre bounds, voxel size, interfaces, and identity. Keep the old evaluator active. | Exact old-vs-new resolved positions at all authored top, bottom, height, route, island, and cap anchors. Old Core density/mesh/payload/topology hashes remain equal where the conversion is exactly representable; otherwise list the precise quantization delta before accepting a new baseline. | No. Core parser/audit can be Linux-only; adapter export needs Unreal BuildHost on the owner's PC. |
|
||||
| 2 | Change owner-facing layout authoring and season serialization to metres. Convert each old slot using its **current resolved physical bounds**, not one global chunk multiplier. Represent any historical gap/overlap explicitly. Default each strate's voxel size to 25 cm. | Same physical top/bottom/height values and field anchors before/after. Run default W12 hashes and matched captures. The report must call out any interface whose two old generator bounds disagree instead of silently forcing them together. | Intended no. Touches `VoxelForgeCoreAdapter.cpp`, `VoxelStrateManager`, season manifest/composer and likely `VoxelWorld`; compile and actor validation require the owner's Unreal PC. |
|
||||
| 3 | Add the common generator request/result contract and adapt `Heightfield2D` and `FloatingIslandFieldV1`; wrap the legacy `UVoxelGenerator` route without moving it yet. Move manager lookups out of evaluator calls in stages. | Per-strate exact density queries, proof classifications, full-detail hashes, whole-view hashes, W1/W8/W12 determinism, and generator-to-legacy route parity. Existing current output hashes remain equal for adapters that preserve their exact physical recipe. | No intended visual change. Unreal adapter/legacy wrappers need owner-PC UHT/build and actor validation; native Core pieces can be audited on Linux. |
|
||||
| 4 | Resolve interface records once in the director; route new seal, cap, void, bedrock-gap, and passage behavior through shared composition. Keep old manifest versions on compatibility adapters. | Preserve density hashes where only a mesh closure was missing. Run the strict LOD0–8 ceiling interior/perimeter audit, edge pairing, same-LOD border hashes, matched captures, and field proofs. Any newly closed boundary is a named expected mesh/payload/topology delta. | Affected boundary mesh may change. Adapter serialization needs owner-PC validation; Core audit can run here. This step fixes thin seals/caps, not the L19 ground ledges. |
|
||||
| 5 | Add the generic explicit-surface and LOD-transition contract. Feed SurfaceWorld ground-profile data into common transition bands; prototype on the measured FI/SW interface. | Produce before/after matched readable captures and full ring tables. Require zero no-hit interface samples and a chosen physical seam-error limit; retain L19 hash equality for unaffected tiles/LODs. For intended changes, list changed mesh/payload/topology hashes and keep density unchanged if the field itself is unchanged. | **This is the step that fixes the L19 ledges.** It changes protected SurfaceWorld LOD2 output, so implement only after the owner approves that specific output change. Unreal capture/collision review is on the owner's PC. |
|
||||
| 6 | Enable a per-strate size map behind the already-resolved contract, initially set to 25 cm on all strates. Add one non-default diagnostic size case only after the default remains green. | At all-25-cm map, reproduce the approved default hashes and captures. Include sorted size-map identity in a negative control; boundary/transition hashes must change when one size changes. Re-run edit-across-boundary, collision, streaming, and W1/W8/W12 checks. | No default change; non-default diagnostic intentionally changes sampling. Touches Unreal reflected settings, snapshot adapter, and world identity; full compile/run requires the owner's PC. |
|
||||
|
||||
### L19 reference hashes
|
||||
|
||||
Representative W12 Clang `-ffp-contract=off`, density / mesh / payload / topology:
|
||||
|
||||
| Whole view | L19 hash |
|
||||
|---|---|
|

| SurfaceWorld | `c10697a8f48380c7 / 4197fc1072f0ff58 / 7b3e616ec9459851 / c879e35592bf33e5` |

|
||||
|
||||
Protected SurfaceWorld LOD0–2 hashes are in the L19 report and should be retained through steps
|
||||
1–4 except for explicitly approved boundary geometry. The whole-view hash gate alone cannot prove
|
||||
that a ring improved; step 5 needs the strict ring table and readable captures as well.
|
||||
|
||||
### Owner decisions this design needs
|
||||
|
||||
1. **Preservation target:** confirm that migration snapshots each current generator's resolved
|
||||
physical bounds (including any current overlap or gap) before later tuning them into a single
|
||||
authored metre layout. If instead the initial migration should force currently different bounds
|
||||
to meet, that is a deliberate world change and needs its own baseline/capture review.
|
||||
2. **Ledge output:** approve the specific SurfaceWorld LOD2/transition change before step 5
|
||||
implementation, as required by the existing protected-output rule.

||||
|
||||
For a SurfaceWorld strate, the supported arrival-to-departure route follows the sampled terrain
|
||||
ground and stays within the mouth placement bounds. The inter-strate departure passage owns the
|
||||
descent from that ground mouth through rock and bedrock. Treating the bottom of a tall SurfaceWorld
|
||||
strate as the route's departure height would ask the walk planner to cross open terrain air; it is
|
||||
the wrong endpoint for the intra-strate route.

|

| SlopedTunnel | Straight-style path with switchbacks as needed, capsule clearance, supported floor, maximum grade and landing geometry. | Swept capsule bounds plus floor envelope; low–medium. |

Thank you, that was a strong first pass. Your scope warning about L76 was right and important. I need to correct my
|
||||
brief: "about 75% of field time is the passage composer" was **wrong**.
|
||||
- L76's term profiler covered only about 6.0M legacy samples for FI (5.6M for TN).
|
||||
- L73 counts about 52M density calls per FI or TN whole view: 512 LOD0 tiles × 44,121, 448 LOD1 × 43,322, and so
|
||||
on.
|
||||
- The measured passage/support cost is about 6.5 of FI's ~40 field worker-seconds (~15%), not 75%. Roughly
|
||||
30 worker-seconds of field time is not attributed to any term we've measured.
|
||||
|
||||
Your gain arithmetic for recommendation 1 inherited that error. Please redo it.
|
||||
|
||||
## Deeper pass (you now have more reasoning budget)
|
||||
|
||||
Examine **the whole generation chain**, end to end, for one cold whole view on the legacy FI/TN path. For each
|
||||
stage, say what it does, how often it runs, what it costs per call (from code structure and the measured numbers),
|
||||
and whether its work is necessary:
|
||||
- world/plan resolution;
|
||||
- tile key selection;
|
||||
- `ClassifyBoxDetailed`;
|
||||
- the dispatch into `AnalyticDensityAt` (and whatever runs for the ~46M calls the term profiler did not see);
|
||||
- the composer;
|
||||
- grid fill;
|
||||
- MC;
|
||||
- normals;
|
||||
- skirts;
|
||||
- ground/cap refinement;
|
||||
- payload;
|
||||
- Unreal publication.
|
||||
|
||||
The central question: **where do the unattributed ~30 worker-seconds most plausibly go?** For example:
|
||||
- a different evaluation path the profiler doesn't instrument;
|
||||
- per-call overhead outside the timed terms (dispatch, stratum lookup, virtual calls, allocation, cache misses);
|
||||
- border/halo samples evaluated twice;
|
||||
- normals sampling the field again;
|
||||
- duplicated work between neighbouring tiles or LODs.
|
||||
|
||||
Give file:line for each. Then name the cheapest measurement that would confirm your top explanation, so the next
|
||||
implementation round can verify it first.
|
||||
|
||||
Then **revise your ranked recommendations** in the light of the whole chain. Keep what still holds and drop what
|
||||
doesn't. Add anything the chain review reveals.

# VoxelForge — design review: how do we get a cold whole view from ~2.5–4.6 s to ~1 s?
|
||||
|
||||
You're reviewing a voxel terrain generator's performance architecture. **Read and reason only.** Don't edit,
|
||||
build, run tests, commit or stash. You may read any file in this repository and search the web.
|
||||
|
||||
We've spent about 15 rounds finding and fixing hot spots, and the gains are shrinking. We want fresh eyes on the
|
||||
*approach*, not another micro-optimisation. Question our framing where it's wrong.
|
||||
|
||||
## The system (summary, so you don't have to rediscover it)
|
||||
|
||||
**VoxelForge** is a UE5 plugin for underground density-field terrain. Generation lives in a standalone C++
|
||||
library, "Core" (`Standalone/Core/`), that Unreal calls through an adapter
|
||||
(`Source/VoxelForge/Private/VoxelForgeCoreAdapter.cpp`).
|
||||
- **The field.** Density is a *function*, not stored data: negative = solid. Core voxels are 25 cm. Tiles hold
|
||||
32³ voxels.
|
||||
- **Clipmap.** LOD0–8; each LOD doubles the voxel step. A "whole view" is about 2,250–2,850 tiles across all LODs
|
||||
around one camera.
|
||||
- **Meshing.** Marching cubes per tile (about 35³ samples per LOD0/1 tile with borders), plus normals and skirts.
|
||||
- **The world is a vertical stack of "strates".** Each is ceiling → content → bedrock, with its own generator:
|
||||
- SurfaceWorld (SW): heightfield, native path;
|
||||
- FloatingIslands (FI), TunnelNetwork (TN) and VerticalShafts (VS): the "legacy compiled-analytic" path.
|
||||
- **The owner's test world** stacks four of them: SW 512 m, FI 240 m, TN 128 m, VS 128 m tall.
|
||||
- **Passages.** Walkable, winding, natural-looking tunnels near (0,0) connect each strate to the next. They're
|
||||
carved by a shared "composer" that also adds support treads, boundary bands and mouth shaping.
|
||||
- **Multiplayer.** No geometry is replicated. Every peer regenerates from the seed, the layout and a diff of
|
||||
player edits. That's why peer determinism is mandatory.
|
||||
|
||||
## The goal and constraints
|
||||
|
||||
- **Goal:** about 1 s cold whole view at any strate arrival on the owner's PC (Ryzen 5800X3D, 8 cores/16 threads,
|
||||
7900 XTX). Streaming must stay smooth in VR (Quest 3) and at high travel speed.
|
||||
- **Must hold:**
|
||||
- peer determinism (same inputs → same world on every machine);
|
||||
- no visible quality regression;
|
||||
- passages stay walkable from arrival mouth to departure mouth (capsule, support and grade audits exist);
|
||||
- no game-thread hitches.
|
||||
- **Not required:** byte-identical output with earlier versions. The owner accepts that perf passes change the
|
||||
world's shape slightly, as long as every peer gets the same result and quality holds. (We have tended to treat
|
||||
hash equality as a gate anyway; it's a convenience, not a rule.)
|
||||
- **On the shelf, not a speed excuse:** a disk mesh cache is an accepted feature, but perf is judged cold.
|
||||
|
||||
## Measurements (owner world, measured on an i9-12900H with 8 workers, headless unless stated)
|
||||
|
||||
**Whole view now** (it was 2.6 / 7.2 / 6.0 / 2.7 s a week ago):
|
||||
|
||||
| Strate | Whole view |
|
||||
|---|---:|
|
||||
| SW | 2.4 s |
|
||||
| FI | 4.6 s |
|
||||
| TN | 4.3 s |
|
||||
| VS | 2.5 s |
|
||||
|
||||
**In Unreal (SW arrival):**
|
||||
- Core work equals headless;
|
||||
- initial set ready at 3.74 s vs headless 2.41 s, the extra being scheduling;
|
||||
- walkable ring 0.4–1.8 s.
|
||||
|
||||
**Where the time goes:**
|
||||
- **L73:** field evaluation inside grid fill is about 40 of FI's 46 worker-seconds (TN 33 of 39). LOD0/1 tiles
|
||||
evaluate about 44k density samples each.
|
||||
- **L74/L75:** sound whole-tile skip proofs now certify about 22–26% of tile visits.
|
||||
- Ceiling: 46–82% of LOD0–2 tiles are truly uniform, and 90–97% of samples lie in uniform 8³ blocks.
|
||||
- Dominant remaining veto: tiles crossing a strate boundary.
|
||||
- Legacy sub-tile (block) proofs were unsound once (missed passage wall/floor relief), then sound but slower
|
||||
than they saved.
|
||||
- **L76, per legacy sample:**
|
||||
- passage/support composer ≈ **1.05 µs**;
|
||||
- primitive scan ≈ 0.19 µs (0.25 primitive distance evaluations per sample, binned);
|
||||
- boundary band ≈ 0.06 µs;
|
||||
- noise ≈ 0.01 µs.
|
||||
|
||||
**About 75% of field time is the passage composer, even far from passages.**
|
||||
- Per-tile passage culling was tried and changed 612 density samples / 24 mesh tiles. It was rejected only for
|
||||
breaking hash equality, which is a convenience, not a rule; nobody checked whether that change was harmless.
|
||||
|
||||
**Tried and rejected:**
|
||||
- the native FI generator (fails passage walk audits on this plan);
|
||||
- deeper Unreal queues (done: 4.78 → 3.74 s).
|
||||
|
||||
**Trap we fell into once:** a diagnostic hash mode silently disabled the skips and doubled the timings. Measure the
|
||||
production path.
|
||||
|
||||
## What to reason about (open; don't limit yourself to these)
|
||||
|
||||
1. **Is "evaluate a density function at ~44k points per tile, then march cubes" the right shape** for this world?
|
||||
Consider, for example:
|
||||
- sparse/hierarchical evaluation (octree or brick refinement driven by interval or Lipschitz bounds, as in
|
||||
libfive/Fidget/MPR-style implicit rendering);
|
||||
- reusing samples across nested clipmap LODs;
|
||||
- evaluating smooth large-scale terms coarsely and interpolating;
|
||||
- narrow-band evaluation near the surface only.
|
||||
2. **The passages are a few winding tubes.** Why does every sample pay 1 µs for them? What representation would
|
||||
make "far from any passage" free and "near a passage" cheap? For example:
|
||||
- bake each passage once at plan time into a sparse distance/brick structure;
|
||||
- a spatial index of segments with a conservative distance early-out;
|
||||
- a per-tile passage candidate list built once.
|
||||
|
||||
What would a correct per-tile culling need so that it doesn't change the result? And if it changes the result,
|
||||
how should we judge whether that change is acceptable?
|
||||
3. **Which work is needed for "ready in 1 s"?** Maybe the target should be redefined: walkable ring first,
|
||||
progressive LOD refinement, far LODs from cheaper representations or impostors, fewer tiles. What do comparable
|
||||
engines do (Voxel Plugin, Teardown, Dreams, No Man's Sky, Minecraft-style streaming, Nanite-era voxel work)?
|
||||
4. **Hardware.** 8 CPU cores plus a 7900 XTX that's mostly idle during load. An earlier GPU port was closed, and
|
||||
determinism across GPU vendors is a concern. Is there a deterministic way to use it, e.g. integer/fixed-point
|
||||
evaluation or a CPU-authoritative plus GPU-display split? Is SIMD (AVX2) evaluation of the legacy field
|
||||
realistic?
|
||||
5. **Anything in our process or measurement** that hides the real bottleneck.
|
||||
|
||||
## How to work efficiently
|
||||
|
||||
- **Trust the numbers above; don't re-measure or re-derive them.** Spend your effort on thinking.
|
||||
- **Read code only to check whether a specific idea fits.** Entry points:
|
||||
- `CODEMAP.md` (navigation) and `ARCHITECTURE.md` §8.10 (performance invariants);
|
||||
- `Standalone/Core/src/ShapeWorldInternal.h`: composer, `AnalyticDensityAt`, `ClassifyBoxDetailed`, passage
|
||||
terms;
|
||||
- `Standalone/Core/src/VoxelForgeCore.cpp`: tile generation and skips;
|
||||
- reports in `Standalone/Research/WorldAssemblerM3/`: `Linux73`–`Linux76`, `Research36`, and R38–R40 notes
|
||||
inside `Linux73/` and `Linux76/`.
|
||||
- **Use the web** for prior art and techniques, and cite them.
|
||||
- **Go broad first** (many approaches, one or two lines each), then deep on the best three.
|
||||
|
||||
## Output
|
||||
|
||||
At most ~2,500 words, plain language, **ranked recommendations first**. For each of the top three:
|
||||
- what changes, and where in this codebase (file and function);
|
||||
- expected gain, with arithmetic from the numbers above;
|
||||
- what it risks: determinism, quality, walkability;
|
||||
- effort;
|
||||
- **a cheap experiment that would prove it wrong** before anyone builds it fully.
|
||||
|
||||
Then the shorter list of other ideas, then any questions only the owner can answer (e.g. what "ready" must mean).

||||

# Astra 1, pass 2 — whole-chain review (gpt-6-astra, effort medium, read-only), 2026-10-27
|
||||
|
||||
Claude verified: PackedDensityAt (ShapeWorldInternal.h ~5909) applies ApplyResolvedStrateComposition outside the L76 term scope; FScopedDensityQueryProfile times whole invocations crossing a 256-point boundary (batch-biased).
|
||||
|
||||
**Stage-by-stage cost map**
|
||||
|
||||
[MEASURED] The L73 stage timings below are historical, before the later skips. They describe where that run spent time; they cannot be subtracted from L76 term timings to produce a current residual. I also inspected the saved L76 results without executing generation.
|
||||
|
||||
[CODE] A major architectural detail: the “compiled-analytic” world **already contains precomputed packed signs and quantized surface-distance proxies**. Many lattice queries never enter `AnalyticDensityAt`.
|
||||
|
||||
| Stage | Work and frequency | Cost and necessity |
|
||||
|---|---|---|
|
||||
| **World/plan resolution** | [CODE] Headless loads the owner export, resolves/validates its layout, constructs a snapshot, then constructs `World`. Once per cold run. UE’s serialization entry is [`VoxelForgeCoreAdapter.cpp:2062`](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelForgeCoreAdapter.cpp:2062); headless startup begins at [`StreamBenchmarkHeadless.cpp:1659`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/StreamBenchmarkHeadless.cpp:1659). | [MEASURED] Saved L76 FI owner-data loading takes about **25 ms**. No complete isolated resolution cost is supplied. [INFERENCE] Necessary, but not a plausible home for worker time measured inside tile-field queries. |
|
||||
| **Shape compilation** | [CODE] `World::compile` builds primitives/bins, packed rock intervals, candidate bands, detailed distance proxies, sign-edge repairs, passage validation and far parents. Once for the base shape; additional pages when needed. [`VoxelForgeCore.cpp:1394`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:1394), [`ShapeWorldInternal.h:2724`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:2724). | [MEASURED] Saved L76 FI: **313 ms wall**, including approximately 48 ms shapes, 64 ms intervals/signs, 62 ms surface band and 119 ms far parents. [INFERENCE] Important to a one-second cold budget, but separate from the missing tile-field attribution. It already amortizes substantial base-field work. |
|
||||
| **Tile-key selection** | [CODE] `desiredTiles` builds clipmap keys, vertical bounds and additional far surface columns. Once initially, then on streaming-set changes; about 2,250 tiles for FI/TN. [`VoxelForgeCore.cpp:1904`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:1904). | [INFERENCE] Thousands of key/set operations, not millions of field evaluations. No measured isolated cost. Necessary selection; exact tile count remains a design choice. |
|
||||
| **Whole-tile classification** | [CODE] Each assembly tile calls `ClassifyBoxDetailed`, including a one-step halo. It delegates to `ClassifyBoundsDetailed`, with conditional slicing and conservative vetoes. [`VoxelForgeCore.cpp:2377`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:2377), [`ShapeWorldInternal.h:6385`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:6385). | [MEASURED] L73: only **4/3 ms total FI/TN**, roughly **2/1 μs per tile**, but ineffective legacy skips then. These are not current classifier costs. [INFERENCE] Necessary only when avoided work pays for it; retain current profitable proofs. |
|
||||
| **Density dispatch and base evaluation** | [CODE] Scalar lattice queries probe native/legacy-surface paths, then choose packed lookup or analytic evaluation. Batches have additional fast paths. [`ShapeWorldInternal.h:3475`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:3475), [`:3602`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:3602), [`:5909`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:5909). | [MEASURED] L73’s approximately 52M calls and 39.9/33.2 field worker-seconds imply roughly **0.77/0.64 μs per counted point**, averaged over heterogeneous paths. [INFERENCE] Fetching/evaluating the base value is necessary; repeated dispatch is not inherently necessary. |
|
||||
| **Composer** | [CODE] Packed and scalar analytic paths both call `ApplyResolvedStrateComposition`: cavern graph → boundary → passage/support → stamps → compatibility floor caps. [`ShapeWorldInternal.h:1993`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:1993). Frequency depends on the actual route, not just the strate label. | [MEASURED] L76 measures approximately **6.5/5.5 worker-seconds** only within its eligible analytic scopes. [CODE] Its passage/support bucket also includes `ApplyResolvedCavernFloorCaps` at [`:2053`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:2053). [INFERENCE] Composition is necessary where influential; universal invocation is not. |
|
||||
| **Grid fill** | [CODE] One cached lattice per generated tile: typically **35³ = 42,875** points at LOD0/1, including halo. Scalar, X8 or Z-run traversal fills it. Storage is thread-local and reused. [`Standalone mesher:430`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:430), [`:957`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:957), [`:1296`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:1296). | [MEASURED] L73: **36.14/29.37 s**, approximately **16.1/13.2 ms per visited tile**, including evaluation. [INFERENCE] Dense fill is avoidable in proven-uniform regions. This is the primary workload, not merely array writes. |
|
||||
| **Marching cubes** | [CODE] Classifies cells using cached corners, computes geometry only for surface cells, interpolates edges and deduplicates vertices. LOD0 midpoint correction can issue extra unclamped queries. [`Mesher:1879`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:1879), [`:1943`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:1943). | [MEASURED] L73 MC aggregate: **40.58/32.63 s**, including grid work. Subtracting grid gives about **4.44/3.26 s**, not another 40 seconds. [INFERENCE] Necessary extraction, but replacing MC is not the first lever. |
|
||||
| **Normals** | [CODE] Central differences normally read the existing grid. At Step 1, proxy-band fallback values trigger `DensityAtUnclamped`; optional gradient memoization avoids repeated corner gradients. [`Mesher:1654`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:1654). | [MEASURED] L73: **0.306/0.246 s**, about **0.14/0.11 ms per visited tile**. [INFERENCE] Some repeated field queries exist, but six new field evaluations per vertex is not the general path. Normals cannot plausibly explain 30 seconds under these measurements. |
|
||||
| **Skirts** | [CODE] Boundary-edge detection, extrusion and density probes prevent unsuitable skirt geometry. Work scales with boundary geometry, not tile volume. [`Mesher:2111`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:2111). | [MEASURED] L73: **1.079/1.091 s**, approximately **0.48/0.49 ms per visited tile**. [INFERENCE] Necessary for the current seam solution; bounded opportunity, not the missing dominant cost. |
|
||||
| **Ground/cap refinement and far shells** | [CODE] Far stratum/connector repairs and native ground/cap refinement run under eligibility gates, with refinement at LOD≥4 and no overlapping edits. [`VoxelForgeCore.cpp:2792`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:2792), [`:2875`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:2875). | [MEASURED] L73’s combined “Other,” including these and assembly, is **2.86/2.78 s**. [INFERENCE] Required by the current far representation, but partly corrective work that a better far representation could avoid. Not an explanation for missing grid time. |
|
||||
| **Payload** | [CODE] Core assembles material/vertex/index outputs; the headless wrapper converts vertices and moves indices/masks. Per output vertex/index, once per tile. [`VoxelForgeCore.cpp:2969`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:2969), [`StreamingWorld.h:934`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/StreamingWorld.h:934). | [MEASURED] The separately timed headless conversion is **12 ms total**, about **5 μs per tile**. [INFERENCE] This does not include all Core assembly or Unreal upload/collision costs. It is not a useful primary target. |
|
||||
| **Unreal publication** | [CODE] Worker generation → prepared streams → result queue → budgeted game-thread component/upload/section work → asynchronous collision completion. [`VoxelWorld.cpp:13303`](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelWorld.cpp:13303), [`:9400`](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelWorld.cpp:9400), [`:14010`](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelWorld.cpp:14010), [`:14279`](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelWorld.cpp:14279). | [MEASURED] SW has **1.33 s additional readiness latency**. [INFERENCE] That is not 1.33 s of CPU publication work. Per-tile apply/cook costs are not established here. Essential to the target, but cannot explain headless field time. |
|
||||
|
||||
**Where the “unattributed 30 seconds” most plausibly went**
|
||||
|
||||
[CODE] **First: packed-field composition is outside L76’s measurement scope.** The relevant chain is:
|
||||
|
||||
`DensityAtLattice` → `PackedDensityAt` → `ApplyResolvedStrateComposition`.
|
||||
|
||||
`PackedDensityAt` reads `RockWords`, `CandidateWords` and possibly `SurfaceDistanceQ`, then applies composition. It never enters the `FScopedLegacyFieldTermScope` created later inside `AnalyticDensityAt` at [`ShapeWorldInternal.h:5967`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:5967).
|
||||
|
||||
[CODE] Term timers immediately return when that scope is inactive: [`ShapeWorldInternal.h:2275`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:2275). Thus an expensive passage query can be counted by the outer field profiler but entirely absent from L76’s passage timing.
|
||||
|
||||
[CODE] `DensityDispatchPathAt` returns “compiled-analytic/FloatingIslands” from the bound generator kind without distinguishing packed from analytic execution: [`ShapeWorldInternal.h:3455`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:3455). That label is insufficient for performance attribution.
|
||||
|
||||
[CODE] There are further differences:
|
||||
|
||||
- X8 can return packed proxy values directly without invoking the scalar composer; other conditions make it fall back to scalar calls. [`ShapeWorldInternal.h:3675`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:3675)
|
||||
- FI LOD0 preferentially uses scalar vertical traversal. [`Mesher:1288`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:1288)
|
||||
- Z-run dispatch can fall back to scalar lattice queries, including packed queries. Its analytic term scope is reached only after those fallbacks. [`ShapeWorldInternal.h:11460`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:11460)
|
||||
- Native/surface branches and non-FI/TN samples are excluded from the legacy-term population.
|
||||
|
||||
[INFERENCE] Therefore, the correction establishes that **6.5 seconds is measured passage cost within one subset**, not that total passage cost is only 15%. Packed composition is my leading explanation for substantial uninstrumented work. I cannot assign it 30 seconds from source alone.
|
||||
|
||||
[MEASURED] **Second: the residual mixes different generations of the workload.** Existing [L76 saved results](/home/jahni/VoxelM/Plugins/VoxelForge/Saved/Linux/l76/term-profile-before/summary.json) contain:
|
||||
|
||||
| Same saved L76 run | FI | TN |
|
||||
|---|---:|---:|
|
||||
| Density point calls | 26.99M | 25.13M |
|
||||
| Eligible legacy points | 6.01M | 5.56M |
|
||||
| Reported field estimate | 18.19 worker-s | 15.49 worker-s |
|
||||
| Tile-worker total | 33.80 worker-s | 28.56 worker-s |
|
||||
| Whole-view wall | 4.621 s | 3.977 s |
|
||||
|
||||
[INFERENCE] The approximately 46M unseen calls belong to subtracting L76’s eligible count from L73’s pre-skip population. They are not an established current population. Likewise, `40−measured_terms` is not a coherent current residual.
|
||||
|
||||
[CODE] **Third: the aggregate field estimator can be biased by batching.** `FScopedDensityQueryProfile` samples when the point sequence crosses a multiple of 256, timing the entire invocation and recording its point count. The reducer pools sampled time/points and scales by all points. See [`ShapeWorldInternal.h:2355`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:2355) and [`StreamBenchmarkPipeline.h:5611`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/StreamBenchmarkPipeline.h:5611).
|
||||
|
||||
[INFERENCE] A batch of eight has approximately eight times a scalar invocation’s chance of being selected, and contributes eight sampled points when selected. Pooling both without inclusion-probability correction overrepresents batch points. If packed batches are cheap and scalar composition is expensive, the estimate can substantially understate field time. Periodic sampling also risks correlation with spatial traversal.
|
||||
|
||||
[MEASURED] This deserves attention: L76 FI LOD0 records **12.70 s grid fill but only 5.96 s estimated field evaluation**. Conversely, LOD3 estimates **3.04 s field time against 2.58 s total tile-worker time**. Those are diagnostic inconsistencies, not proof of where the discrepancy lies. [Saved log](/home/jahni/VoxelM/Plugins/VoxelForge/Saved/Linux/l76/term-profile-before/strate1-w8.log:12880)
|
||||
|
||||
[INFERENCE] **Lower-ranked explanations:**
|
||||
|
||||
- **Dispatch/lookups:** real repeated work. Stratum lookup uses binary search and coordinate conversion, sometimes repeatedly per sample: [`ShapeWorldInternal.h:437`](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:437). But attributing 30 seconds to this alone means roughly **0.65 μs per purported 46M calls**. That needs evidence; hidden composer execution is more concrete.
|
||||
- **Allocation/cache misses:** possible contributors, but grid allocation is reused and packed access is direct indexing. There is no evidence of one heap allocation per ordinary density point.
|
||||
- **Halos/neighbor duplication:** significant but bounded. `35³−33³ = 6,938`, or **16.2%** of a dense tile’s samples, is the gradient halo. Including shared faces, an ideal large same-LOD region could reduce `35³` toward `32³` unique samples per tile: approximately **23.6%** savings before edges and synchronization. This multiplies existing evaluation cost; it does not create a separate unmeasured stage.
|
||||
- **Normals/midpoints/skirts:** issue additional calls, but their measured stage budgets exclude them as the dominant explanation. Cross-LOD duplication remains unquantified.
|
||||
|
||||
**Cheapest decisive measurement**
|
||||
|
||||
[INFERENCE] First take a sampling call-stack profile of the clean production run, focused on grid fill. It requires no new per-sample timers and should immediately distinguish packed composition from dispatch or memory stalls.
|
||||
|
||||
[INFERENCE] The next instrumentation change should be a **mutually exclusive dispatch census**, not another individual-term profiler. Count and sample time for packed-scalar, packed-X8, analytic-scalar, analytic-batch, native and legacy-surface routes, split by LOD and caller stage. Measure composition inside packed-scalar explicitly.
|
||||
|
||||
Use equal-probability invocation sampling with correct expansion, or stratify by route **and batch length**. Avoid nested double-counting; compare the resulting total against directly timed grid fill. Separate passage carving from compatibility floor caps.
|
||||
|
||||
[INFERENCE] This falsifies my leading explanation if packed-scalar composition occupies little time. Only then prioritize dispatch, cache misses or other overhead.
|
||||
|
||||
**Revised ranked recommendations**
|
||||
|
||||
**1. Establish complete attribution, then specialize the dominant lattice route.**
|
||||
|
||||
[INFERENCE] This replaces my unconditional “passages first” ranking. The first implementation round should produce a closed cost account and identify which route dominates LOD0/1.
|
||||
|
||||
If packed composition dominates, give each tile/brick a stable local composition program and an identity fast path. Extend `FScopedPassageTileQueries`, `PackedDensityAt` and `ApplyResolvedStrateComposition`. Hoist Z-only dispatch decisions into plane/run contexts. Before copying the X8 shortcut into scalar traversal, establish why their composition behavior differs and which semantics are required.
|
||||
|
||||
[INFERENCE] Effort: small for attribution, medium for specialization. Risks: incorrect support envelopes, changed composition order, scalar/batch disagreement. Preserve peer determinism and audit clearance, support and grade; old-version hashes remain an exactness diagnostic.
|
||||
|
||||
[MEASURED → INFERENCE] **Corrected passage arithmetic:** using your historical budget strictly as an illustration:
|
||||
|
||||
- FI, removing 80–90% of **6.5/46** worker-seconds: `4.6 × (1−0.8…0.9 × 6.5/46)` = **4.08–4.02 s**.
|
||||
- TN, removing 80–90% of **5.5/39**: approximately **3.81–3.75 s**.
|
||||
|
||||
These replace my erroneous approximately two-second estimates. They are not forecasts because the operands span rounds. Using the contemporaneous saved L76 totals instead gives approximately **3.91–3.83 s FI**, **3.37–3.29 s TN**, under proportional scaling.
|
||||
|
||||
[INFERENCE] Total passage savings could be larger if the missing packed-route work is substantial. Measure it before assigning a percentage.
|
||||
|
||||
**2. Remove repeated composed sampling; retain MC.**
|
||||
|
||||
[INFERENCE] Keep the retained-proof/local-program recommendation, but build on the existing packed representation. Priorities:
|
||||
|
||||
- Retain successful slice/brick proofs rather than requiring a uniform whole-tile verdict.
|
||||
- Reuse final composed lattice samples across neighboring tiles where inputs and semantics match.
|
||||
- Evaluate exact surface endpoints and normal stencils; leave certified interiors implicit.
|
||||
|
||||
The relevant changes remain `ClassifyBoundsDetailed`, `World::generateTile` and the standalone mesher’s grid fill. Sample-cache keys must include evaluator version, edits and relevant resolution/context—not coordinates alone.
|
||||
|
||||
[INFERENCE] An alternative worth testing is applying composition once to a shared near-region lattice. Count its cold construction cost: moving the same work earlier is not a speedup. It wins through deduplication, localization or cheaper batching.
|
||||
|
||||
[INFERENCE] Effort: medium-to-large. Risks: stale edit dependencies, seams and false uniform proofs. Cheap falsifier: one representative region spanning adjacent tiles and a strate boundary; compare total construction plus meshing cost against independent tiles.
|
||||
|
||||
[INFERENCE] Withdraw the earlier combined one-second projection. At unchanged throughput, FI’s current 4.6 seconds requires approximately **78% critical-path reduction**. Border sharing alone cannot supply that; broad sampling elimination still has to prove its economics.
|
||||
|
||||
**3. Preserve a separate arrival deadline and reduce end-to-end latency.**
|
||||
|
||||
[INFERENCE] Keep dependency-aware scheduling through collision publication, rather than merely increasing queue depth. The existing near-priority and hot-swap mechanisms already provide the foundation.
|
||||
|
||||
Shape compilation’s approximately 0.31 seconds matters once generation approaches one second. Far repair/refinement becomes material too. Optimize these after the dominant grid route is understood; do not hide their cost outside the cold timer.
|
||||
|
||||
[MEASURED → INFERENCE] SW’s scheduling gap remains a possible **0–1.33-second** latency opportunity, not a guaranteed CPU saving. Scheduling cannot remove required whole-view work.
|
||||
|
||||
[INFERENCE] Effort: medium. Risks: starving far coverage or publishing visuals before safe collision. Cheap falsifier: an arrival-only admission experiment plus prerequisite/publication tracing. If its uncontended critical path exceeds one second, scheduling alone cannot meet arrival readiness.
|
||||
|
||||
[INFERENCE] GPU porting, SIMD, native-generator replacement and a new mesher stay below these three. The newly visible distinction is between **cheap cached base density and potentially expensive repeated composition**, not simply “52M analytic evaluations.”

# Astra 1 — design review (gpt-6-astra, effort low, read-only), 2026-10-27
|
||||
|
||||
Brief: see BRIEF.md. Note from Claude: the brief's "~75% of field time is the passage composer" was WRONG — L76's term profiler covered ~6.0M of ~52M density calls per view (FI); measured passage cost is ~6.5 of ~40 worker-s (~15%). Astra flagged the scope mismatch itself. Its gain arithmetic in rec. 1 inherits the wrong share.
|
||||
|
||||
**[INFERENCE] Ranked recommendations:**
|
||||
|
||||
1. **Compile passages into spatially local operations.** Make most samples bypass the composer entirely; simplify the remaining work.
|
||||
2. **Replace repeated block classification with a retained hierarchy of proofs and local field programs.** Keep marching cubes; stop densely evaluating regions that cannot produce geometry.
|
||||
3. **Give arrival readiness its own deadline-driven pipeline.** Preserve whole-view completion as a separate benchmark; scheduling improvements alone cannot meet it.
|
||||
|
||||
**[INFERENCE]** These are complementary. Passage localization is the strongest first investment, but does not plausibly deliver one second alone. A wholesale mesher replacement, GPU rewrite, or native-generator migration is premature.
|
||||
|
||||
### 1. Make passage influence local by construction
|
||||
|
||||
**[CODE]** There is already a spatial index: `BuildPassageFeatureTileList` queries passage feature bounds. `FScopedPassageTileQueries` turns route candidates into per-passage flags, while retaining segment lists for mouth support. Nevertheless, `ApplyResolvedStratePassageCarves` still iterates all passages and scans crossings. After finding a route distance, it calculates relief and mouth-related terms. See [ShapeWorldInternal.h](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:989).
|
||||
|
||||
**[INFERENCE] What changes:** compile a small, immutable passage program for each spatial region:
|
||||
|
||||
- Empty region: no passage invocation.
|
||||
- Route region: ordered candidate segments, precomputed geometry and distances along the route.
|
||||
- Mouth/support region: explicit support, transition-fade and later-bore dependencies.
|
||||
- Overlapping features: retain the original composition order.
|
||||
|
||||
Use `BuildPassageComposerConstants`, `BuildPassageFeatureTileList`, `FScopedPassageTileQueries`, and `ApplyResolvedStratePassageCarves`; connect the result through `World::generateTile` in [VoxelForgeCore.cpp](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:1997). This is stronger than filtering one loop: the region program should remove entire categories of work.
|
||||
|
||||
**[INFERENCE] Exact culling requires an identity proof**, not merely “the tube does not intersect this tile.” For every omitted operation, prove that it leaves the incoming density unchanged over the query domain. Include:
|
||||
|
||||
- Spline extrema, variable radius, wall/floor relief and smooth-blend reach.
|
||||
- Mouth shaping, support treads, columns, boundary fade and dependencies on other passages.
|
||||
- All sample positions used by normals, borders and skirts.
|
||||
- Deterministic ordering and tie-breaking among retained features.
|
||||
|
||||
A feature can leave density signs unchanged while altering marching-cubes interpolation or normals. Conversely, changing far-away density magnitudes may be harmless. These are different correctness claims.
|
||||
|
||||
**[CODE]** L75 already corrected bounds for passage relief and spline extrema. The composer also conditionally restores support and defers support composition. Therefore, baking one distance to the nearest tube would not reproduce its semantics. [L75 report](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux75/REPORT.md:22)
|
||||
|
||||
**[INFERENCE]** If exact influence is awkward or effectively nonlocal, introduce a versioned, compact-support passage operator: identical in the protected walkable corridor and mouth regions, smoothly becoming identity outside an explicit envelope. That is a legitimate world-generation change under your constraints.
|
||||
|
||||
**[MEASURED → INFERENCE] Expected gain:** passage work is approximately `0.75 × 40 = 30` of FI’s 46 worker-seconds, and `0.75 × 33 = 24.75` of TN’s 39. Removing 80–90% gives proportional wall-time scenarios:
|
||||
|
||||
| View | 80% passage reduction | 90% passage reduction |
|
||||
|---|---:|---:|
|
||||
| FI | `4.6 × (46−24)/46 = 2.20 s` | `4.6 × (46−27)/46 = 1.90 s` |
|
||||
| TN | `4.3 × (39−19.8)/39 = 2.12 s` | `4.3 × (39−22.275)/39 = 1.84 s` |
|
||||
|
||||
These assume critical-path time follows work reduction; they are not predictions for the Ryzen. Even eliminating passage cost entirely leaves approximately **1.6 seconds** in both views.
|
||||
|
||||
**[INFERENCE] Risks and effort:** medium effort for regional programs; larger for a new passage representation. Stable candidate ordering and versioned arithmetic protect determinism. Underestimated envelopes threaten clearance and support; overly generous envelopes merely lose speed. Run capsule, grade and support audits across entire passages, including landings and seams.
|
||||
|
||||
**[INFERENCE] Cheap falsifier:** resurrect the rejected culling candidate as an experiment. First inspect all 612 changed samples and 24 changed mesh tiles: location, zero crossings, surface displacement, normals, support and audit outcomes. Then time the production path including candidate construction. Reject this implementation if conservative lists remain large or composer savings are small. Hash differences alone are neither acceptance nor rejection.
|
||||
|
||||
### 2. Retain spatial proofs and simplify the field inside each region
|
||||
|
||||
**[INFERENCE]** A continuous density function remains a good world definition. Evaluating its complete program at every lattice point is the questionable implementation. Marching cubes is not currently the dominant problem.
|
||||
|
||||
**[CODE]** `ClassifyBoxDetailed` delegates to `ClassifyBoundsDetailed`. The latter already performs conditional strate slicing, but combines slices into a whole-box verdict and abandons the skip when a slice is unknown or has a different sign. L75’s legacy block certificates became audit-only after timing regressions. Simply enabling more block checks repeats a failed approach. [Classifier](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:6385), [L75 final disposition](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux75/REPORT.md:64)
|
||||
|
||||
**[INFERENCE] What changes:** introduce a compact region tree or brick table whose entries retain:
|
||||
|
||||
- A solid/air certificate, or an unresolved range.
|
||||
- Relevant primitive and passage candidates.
|
||||
- Terms proven inactive or dominated.
|
||||
- Child regions requiring further evaluation.
|
||||
|
||||
Split first at known strate and transition-band boundaries, then refine unresolved regions spatially. Keep successful proofs even if a neighboring slice fails. Share candidate filtering and bounds down the hierarchy; do not repeatedly invoke the full classifier from scratch.
|
||||
|
||||
Start tile-local and retain the regular marching-cubes lattice. Extend `ClassifyBoundsDetailed`, the evaluation feeding `AnalyticDensityAt`, `World::generateTile`, and the grid/proof path in `UVoxelMarchingCubesMesher::GenerateMesh` in [VoxelMarchingCubesMesher.cpp](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp:102).
|
||||
|
||||
**[PRIOR ART]** Fidget combines interval evaluation with regional expression simplification: even unresolved regions can use shorter programs. That second benefit matters here as much as empty-space skipping. It also supports bulk SIMD evaluation. [Fidget’s author documentation](https://www.mattkeeter.com/projects/fidget/)
|
||||
|
||||
**[INFERENCE]** Do not assume the composed density is a signed distance field with Lipschitz constant one. Warps, blends and relief require their actual bounds. Uniform corners do not prove a uniform interior.
|
||||
|
||||
Similarly, do not fill certified interiors with arbitrary constants and then use those constants at surface edges or in normal stencils. Evaluate the exact endpoint and halo values wherever geometry or gradients consume them. A narrow band must be *discovered conservatively*, not guessed from sparse signs.
|
||||
|
||||
**[MEASURED → INFERENCE] Expected gain:** the 90–97% uniform-block sample census is an opportunity ceiling, not a realizable skip rate. A useful experiment target is **50–70% reduction of remaining field work, net of classification cost**.
|
||||
|
||||
After a 90% passage reduction, FI has approximately 13 field-work units plus 6 others. Reducing those 13 by 50–70% gives:
|
||||
|
||||
`4.6 × [6 + 13 × (0.5 to 0.3)] / 46 = 1.25 to 0.99 s`.
|
||||
|
||||
TN similarly gives approximately **1.25–1.02 seconds**. Thus the combination approaches the headless target, with little budget left for Unreal overhead. Do not multiply independent headline speedups: both techniques remove overlapping work.
|
||||
|
||||
**[INFERENCE] Risks and effort:** medium-to-large effort, substantially less than adaptive meshing with new topology. Incorrect proofs can silently delete geometry; edits must invalidate affected certificates, including their dependency halos. Quality and walkability can remain unchanged if surface samples and stencils remain exact. Unknown bounds must fall back.
|
||||
|
||||
**[INFERENCE] Cheap falsifier:** implement one tile-local hierarchy for representative boundary-crossing and passage-adjacent tiles, retaining the existing mesher. Compare total classification-plus-fill cost against dense evaluation, after passage localization. Reject expansion if net field savings fall well below 50%, or bookkeeping and conservative halos consume the benefit. The prior slow block experiment makes this an essential early gate.
|
||||
|
||||
### 3. Schedule for an explicit arrival deadline
|
||||
|
||||
**[MEASURED]** SW’s Unreal overhead is `3.74−2.41 = 1.33 s`; walkable readiness ranges from 0.4 to 1.8 seconds.
|
||||
|
||||
**[INFERENCE]** Keep two separate commitments:
|
||||
|
||||
- **Arrival ready:** safe collision and sufficient visible terrain for immediate movement.
|
||||
- **Whole view complete:** the full requested set at final quality.
|
||||
|
||||
If the owner insists both happen within one second, say so explicitly. Progressive refinement cannot be counted as meeting the second commitment.
|
||||
|
||||
**[CODE]** §8.10 already specifies occupied/support-tile priority, heading priority, dynamic near reserve, independent region admission, cancellation, bounded result backlog and hot-swap. “Make nearby tiles higher priority” is therefore not a new recommendation. [Performance invariants](/home/jahni/VoxelM/Plugins/VoxelForge/ARCHITECTURE.md:572)
|
||||
|
||||
**[INFERENCE] What changes:** make readiness a dependency graph with deadlines: required region compilation → field/mesh → collision preparation → bounded publication. Prioritize prerequisites of the arrival set, not just its tile jobs. Reserve capacity through publication, and schedule travel-ahead work by time-to-arrival.
|
||||
|
||||
Inspect and change `AVoxelWorld::UpdateChunksAroundPosition`, `LoadTile`, and `ProcessPendingChunks` in [VoxelWorld.cpp](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelWorld.cpp:9400). Preserve the existing epoch, cancellation and collision-handoff rules. Refinement should retain covering geometry until replacements are ready.
|
||||
|
||||
**[PRIOR ART]** Voxel Plugin separates collision/navmesh demand through invokers. Geometry clipmaps use incremental updates, coarse-to-fine processing and continuity between levels. These support separate readiness domains, not a universal one-second guarantee. [Voxel Plugin](https://docs.voxelplugin.com/2.0p6/knowledgebase/blueprints/collision-navmesh-and-invokers), [Geometry clipmaps](https://developer.nvidia.com/gpugems/gpugems2/part-i-geometric-complexity/chapter-2-terrain-rendering-using-gpu-based-geometry)
|
||||
|
||||
**[MEASURED → INFERENCE] Expected gain:** removing half the observed scheduling gap saves about **0.67 seconds**; removing all of it still leaves SW at 2.41 seconds before Core changes. Improving a 1.8-second walkable arrival to one second requires eliminating or deferring 0.8 seconds from that critical path.
|
||||
|
||||
**[INFERENCE] Risks and effort:** small-to-medium for dependency scheduling; larger for new far representations. Timing must never change generation inputs. Coarse collision can violate walkability; coarse visuals can pop, particularly in VR. Preserve authoritative near collision and accept temporary visual substitutes only if they satisfy the owner’s quality criterion.
|
||||
|
||||
**[INFERENCE] Cheap falsifier:** first replay existing job timings against the dependency graph, then try an arrival-only admission experiment. If prerequisites plus bounded publication already exceed one second without competing work, scheduling cannot solve arrival latency. If the coarse cover visibly degrades the arrival, it cannot redefine “ready.”
|
||||
|
||||
**Other approaches, in priority order**
|
||||
|
||||
- **[INFERENCE] Bake passage geometry, not necessarily final density.** Precompute spline coefficients, arc lengths, frames and conservative segment bounds first. Sparse sampled bricks are a later option; retain separate carve/support operands and conditions. Count baking in cold latency. Interpolated distance alone can erase treads or alter mouths.
|
||||
- **[INFERENCE] SIMD after localization.** AVX2 evaluation of batches sharing a local program is realistic; divergent all-passage loops are a poor starting point. Eight lanes do not imply eightfold speedup. Specify arithmetic and reduction order across scalar/vector paths.
|
||||
- **[INFERENCE] Sample sharing.** Share same-LOD borders first; cross-LOD reuse requires identical coordinates *and field semantics*. Nested lattices overlap, but clipmap shells need not cover the same volume. Compare synchronization cost against duplicate evaluation before building a global cache.
|
||||
- **[INFERENCE] Coarse smooth terms.** Interpolate bounded macro terms while evaluating fine relief near surfaces. Density error does not imply equal position error where gradients are weak. L76’s 0.01-µs noise row is too small to justify making noise approximation the main project.
|
||||
- **[INFERENCE] GPU.** A specified integer/fixed-point evaluator can be deterministic: define rounding, overflow, square roots, interpolation and stable emission order. Quantizing floating-point results afterward is insufficient. CPU-authoritative collision plus GPU display is easier, provided visual disagreement is bounded and display results never affect gameplay. GPU readbacks and VR contention can erase gains.
|
||||
- **[PRIOR ART → INFERENCE]** HLSL `precise` controls arithmetic refactoring; it is not a complete cross-vendor world-generation specification. Prototype one bounded integer passage kernel before reopening a full port. [Microsoft documentation](https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/precise)
|
||||
- **[PRIOR ART → INFERENCE] Alternative renderers.** Dreams’ published architecture evaluates CSG into multiresolution point clouds; Teardown uses a voxel renderer without polygons. These demonstrate representation choices, not transferable cold-generation timings. Nanite addresses rendering downstream of field generation. [Dreams presentation](https://www.advances.realtimerendering.com/s2015/index.html), [Teardown FAQ](https://www.teardowngame.com/faq.html)
|
||||
- **[PRIOR ART → INFERENCE] Continuous streaming.** No Man’s Sky’s architecture is explicitly organized around continuous generation. That supports travel-ahead planning, but does not prove cold teleport latency. Disk caching likewise remains useful without counting toward this target. [Hello Games’ GDC talk](https://www.youtube.com/watch?v=sCRzxEEcO2Y)
|
||||
|
||||
**Process changes that matter**
|
||||
|
||||
**[INFERENCE]** Separate three gates: peer determinism for the *new version*; gameplay/visual acceptance against the previous version; and performance on the production path. Old-version hash identity should only gate changes advertised as exact.
|
||||
|
||||
**[CODE]** L76’s term profiler covers selected legacy evaluations; its passage total is about 6.3 worker-seconds, whereas L73 reports broader grid-field totals. Those scopes must not be silently equated. The arithmetic above uses your supplied aggregate attribution as a scenario, not reconciled absolute profiling data. [L76 profiler scope](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux76/REPORT.md:5)
|
||||
|
||||
**[INFERENCE]** Report cold-start boundaries, critical-path stages, worker occupancy, publication latency and worst frame time alongside whole-view time. Include plan compilation and fresh in-memory structures. Validate the winning prototype on the 5800X3D; no reliable conversion follows from the laptop measurements alone.
|
||||
|
||||
**Questions only the owner can settle**
|
||||
|
||||
- Must every final-quality tile exist at one second, or can safe arrival precede complete refinement?
|
||||
- What travel speed, teleport distance and VR frame budget must streaming sustain?
|
||||
- Does “cold” include world planning, and must supported peers reproduce density bits, mesh bits, or an explicitly defined gameplay representation?

The L9 Clang timing/hash baseline is `Standalone/bin/linux/VoxelForgeCoreHeadless-linux9-clang`, SHA-256 `0cd3f0ef993ced2c615418c6e2b37b83f57eff6d024d7d1568c30ea51490384a`.
|
||||
|
||||
## 1. Startup phases
|
||||
|
||||
SurfaceWorld seed 0, W12, no hash; five runs on the optimized Clang build. Wall and process CPU are medians. Process CPU sums work across threads. First-tile time is from cold start; its CPU column is CPU since pool start.
|
||||
|
||||
| Phase | Wall ms | Process CPU ms | Threads used |
|
||||
|---|---:|---:|---|
|
||||
| Owner data load and resolve | 5.05 | 5.05 | 1 |
|
||||
| Assembly plan build | 51.04 | 51.03 | 1 |
|
||||
| Core snapshot | 0.53 | 0.54 | 1 |
|
||||
| First desired-set build, 2,553 tiles | 0.74 | 0.74 | 1 |
|
||||
| Shape request setup | 0.03 | 0.03 | 1 |
|
||||
| Shape compile | 222.59 | 856.79 | caller + up to 8 scheduler workers |
|
||||
| Streamer setup | 0.01 | 0.01 | 1 |
|
||||
| Worker-pool start | 0.41 | 1.27 | 12 requested; 8–11 had entered at print |
|
||||
| First tile starts at 299.62 ms | — | 1.59 since pool start | 12/12 entered |
|
||||
|
||||
Shape-compile wall ranged 215.89–324.88 ms; first tile started at 286.56–409.76 ms. Owner load, plan, local shape setup, and far-parent construction are serial. Before the pool starts, there are no sleeping stream workers, but most of the 12 allowed CPUs are unused. During the interval and detail-band phases the scheduler uses at most 8 workers, leaving up to 4 CPUs unused.
|
||||
|
||||
The phase-trace mode’s whole-view median was 1.436 s, versus 1.372 s with tracing off. The phase runs are for decomposition only; the performance ranking and A/B below use the optimized build with tracing disabled and hashing off. In that flag-off path, shape wall time was 0.222 s median, consistent with the phase trace.
|
||||
|
||||
## 2. Shape contents and first-tile dependencies
|
||||
|
||||
| Shape phase | Wall ms | Process CPU ms | Work / concurrency |
|
||||
|---|---:|---:|---|
|
||||
| Local owner shapes and spatial bins | 40.46 | 40.44 | Extracts owner primitives; 1 thread |
|
||||
| Rock intervals, signs, candidate bands | 40.20 | 187.14 | Packed column signs and candidate masks; up to 8 workers |
|
||||
| Detail band and sign-edge distances | 81.00 | 568.78 | Applies coherent detail to candidate nodes and builds distance proxies; up to 8 workers |
|
||||
| Route validation and shared-field setup | 1.12 | 1.13 | 5,642 passage samples; then shared primitive form |
|
||||
| Far parents and bins | 55.56 | 55.57 | 6,050 far rooms / 18,348 links; 1 thread |
|
||||
|
||||
The compile extracts 18,348 owner primitives (71 rooms, 74 tunnels, 2 passages), covers 138,188,413 sign nodes, allocates 36.71 MiB of packed words and 263.57 MiB of proxy address capacity, and visits 214,538 detail candidates (6,098 flips).
|
||||
|
||||
For this SurfaceWorld fixture, the first LOD0 tile’s density queries take the native `Heightfield2D` path before packed-shape lookup. Far-parent shapes are not needed by that first tile. However, `World::generateTile` rejects requests until the full base shape is marked built, and `compileTileRegion` also requires that base shape. So the current API gates the near tile on the interval, detail, validation, and far-parent work even when that tile does not sample those arrays. Other recipes and fallback/query paths do use the analytic primitives and packed signs/proxies.
|
||||
|
||||
There is no seed-independent owner shape payload to cache at build time. The assembly plan is built from owner data; region pages also re-run owner primitive extraction, spatial-bin construction, and shared-field packing. Those immutable owner-derived structures are a possible per-world reuse target, but the measured short crossings below built no pages, so this run does not price that work.
|
||||
|
||||
## 3. Moving crossing
|
||||
|
||||
Hashing off, W12, same camera and already-streamed initial view. Region compile was called, but all entering fine keys were covered by the initial shape bounds; it built zero regions.
|
||||
|
||||
| Camera step | New tiles | LOD breakdown | Region compile | Tile work wall | Crossing total |
|
||||
|---|---:|---|---:|---:|---:|
|
||||
| 8 m | 144 | LOD2: 128, LOD3: 16 | 0.010 ms | 12.61 ms | 12.81 ms |
|
||||
| 16 m | 288 | LOD0: 128, LOD1: 16, LOD2: 128, LOD3: 16 | 0.010 ms | 60.49 ms | 60.68 ms |
|
||||
|
||||
The 16 m crossing’s worker-time sum was 633 ms; its wall time was 60.5 ms. No plan or full shape compile repeated. A 24 m attempt terminated with `std::bad_alloc` after base shape compilation and before crossing metrics; the failing allocation site is unknown.
|
||||
|
||||
## 4. Ranked levers
|
||||
|
||||
| Rank | Lever | Upper bound from these measurements | Assessment |
|
||||
|---:|---|---|---|
|
||||
| 1 | Overlap near-tile work with shape compilation | 222.6 ms, 16.2% of 1.372 s whole-view-ready; first tile could start earlier by up to the compile time | Largest opportunity. Not built: tiles and region compilation currently require a fully built base shape. A safe version needs immutable partial-page publication and a wait before any tile reads an unfinished sign, proxy, primitive bin, or far field. |
|
||||
| 2 | Defer far-parent construction until far tiles need it | 55.6 ms, at most 4.1% of whole-view-ready and 18.6% of the first-tile delay | Could improve spawn, but far and near paths share mutable spatial-bin state today. Needs separate immutable bins and a synchronized readiness state; no crossing benefit was measured. |
|
||||
| 3 | Parallelize assembly-plan construction | 51.0 ms, at most 3.7% of whole-view-ready | Serial and seed/owner-specific. No safe deterministic parallel split was established. |
|
||||
| 4 | Raise shape scheduler cap from 8 to 12 | About 121 ms currently lies in the two worker phases; ideal linear scaling saves about 40 ms (2.9% of whole-view-ready) | Below the 3% bar before overhead, and no crossing benefit. Not built. |
|
||||
|
||||
For any future partial or deferred build, hashes can fail if a tile observes a partially written sign/proxy array, if region publication races with tile lookup, or if shared bins change while a tile is sampling. The page must be immutable before publication; worker-count and timing tests must compare W1 with W12 and repeat W12. Any asynchronous result must also follow the Epoch/MPSC shutdown-drain rules.
|
||||
|
||||
## 5. Final-build timing and hashes
|
||||
|
||||
Five interleaved W12 runs, no hash. Pair values are `whole_view_ready / stream_wall` in seconds.
|
||||
|
||||
| Pair | L9 `7650abb` Clang | L10 Clang | Delta, ms |
|
||||
|---:|---:|---:|---:|
|
||||
| 1 | 1.336 / 1.050 | 1.346 / 1.060 | +10 / +10 |
|
||||
| 2 | 1.351 / 1.062 | 1.365 / 1.073 | +14 / +11 |
|
||||
| 3 | 1.359 / 1.073 | 1.374 / 1.083 | +15 / +10 |
|
||||
| 4 | 1.363 / 1.077 | 1.375 / 1.081 | +12 / +4 |
|
||||
| 5 | 1.387 / 1.089 | 1.372 / 1.092 | −15 / +3 |
|
||||
| **Median** | **1.359 / 1.073** | **1.372 / 1.081** | **+13 / +8** |
|
||||
|
||||
The measurement-only candidate is +1.0% whole-view-ready and +0.7% stream median; this is no demonstrated speedup. Hashing was off for these timings.
|
||||
|
||||
Final rebuilt binaries passed SurfaceWorld and FloatingIslands seed-0 hash checks at W1, W8, and five W12 runs per compiler: Clang FP contraction off and GCC default. Every full-detail, whole-view, LOD0–8, and exact-query row matches the compiler-matched L9 baseline. Audit files: `Saved/Linux/l10_final_surface_hash_audit.txt` and `Saved/Linux/l10_islands_hash_audit.txt`.
|
||||
|
||||
| Recipe / scope | Density | Mesh | Payload | Topology |

||||
|---|---|---|---|---|
|

| SurfaceWorld full detail | `0x0ee0579bd15cbbe4` | `0x32e5d4964d610fee` | `0x1932b96ee4b1d910` | `0x69743c6bad3447dc` |

|
||||
| FloatingIslands full detail | `0x6d842d2878b08ef6` | `0x4b868a3184f08035` | `0x2cedf2236788752d` | `0xeac17d5e0cb5044a` |

Exact-query hashes also match: SurfaceWorld density `0xe4d4a8eb95b35933`, detail `0xefcba20c0c70c415`, collision `0xe604823a249029bf`; FloatingIslands density `0x61daded9c303becb`, detail `0xefcba20c0c70c415`, collision `0x84d37463be9b0573`.
|
||||
|
||||
## 6. Failed or retried runs
|
||||
|
||||
- One phase smoke omitted the explicit owner-data path and resolved it under `Standalone/bin/data`; reran with `Standalone/data/owner_world.json`.
|
||||
- A no-camera phase smoke produced 2,370 tiles instead of the 2,553-tile fixture; discarded it and reran with the fixed camera.
|
||||
- A malformed `--workers=w8` command exited during argument parsing; reran with numeric `--workers=8`.
|
||||
- The first FloatingIslands matrix invocation omitted the three required streaming-mode switches. All 14 attempts exited before generation; corrected the command and all 14 final runs passed.
|
||||
- The 24 m crossing attempt failed with `std::bad_alloc` as described above.
|
||||
- The first hash-audit parser expected 13 rows; the actual audit contains 12 scopes. Corrected the parser and all final comparisons passed.
|
||||
|
||||
At spawn, the first tile starts about 300 ms after cold start, with roughly 223 ms in full shape compilation and 51 ms in the single-threaded plan; this round did not make that wait shorter. While moving, the 16 m crossing completed 288 entering tiles in about 61 ms and repeated no shape compile, so the measured delay was tile work rather than region setup.

## Orchestrator review (Claude)
|

- **Not committed:** the L10 telemetry code. It is +1.0% whole-view median with tracing off (4 of 5

|
||||
- **Key finding, for L11:** the first SurfaceWorld tiles take the native `Heightfield2D` path and don't
|
||||
read the cave shape, yet `World::generateTile` waits for the full base shape (~223 ms). A per-tile
|
||||
readiness check (start tiles whose recipe path provably never touches shape arrays) is lever #1 in
|
||||
safe form.
|
||||
- **Open bug, for L11:** the 24 m crossing died with `std::bad_alloc` under the 6 GiB **address-space**
|
||||
cap (`RLIMIT_AS`). That cap counts reservations, not resident memory; L10 also reports 263.57 MiB
|
||||
of proxy address *capacity*. It is not yet known whether this is a real memory blow-up on larger
|
||||
crossings or the cap counting reserved address space. L7's 32 m step also hit the 160M-node
|
||||
interval bound.

|

|

## 24 m crossing crash
|
||||
|
||||
The crash is real. The original binary threw `std::bad_alloc` after base shape compilation with both 6 GiB and 16 GiB `RLIMIT_AS`; the 16 GiB run peaked at 476,128 KiB RSS and 1,542,284 KiB virtual size. The allocation trace identifies a 432,345,551,342,665,824-byte resize in `BuildSpatialBins`, reached from `BuildAnalyticRegion` during `World::compileTileRegion`. The crossing code had coalesced disjoint entering tiles into a large LOD rectangle and tried to allocate dense per-axis bins that the analytic fallback never reads. L10's 263.57 MiB figure is the proxies' reserved virtual capacity; RSS samples record resident usage separately.
|
||||
|
||||
Analytic regions now skip those dense bins and compile in world-aligned 128-voxel pages. Pages are built privately and published together; coordinate, `bad_alloc`, and size failures return errors before partial pages are published. On the final L11 binary, 24 m and 32 m both passed (16 pages each); 1,000 m passed with 2,260 entering keys, 72 pages, 63 ms region-build wall time, 700,232 KiB peak RSS, and 2,578,588 KiB peak virtual size. The fixed 24 m run peaked at 533,420 KiB RSS and 2,578,588 KiB virtual size. Crossing pages build no packed interval nodes (`lattice_nodes=0`) and do not expand the immutable base sign/proxy arrays; they add analytic primitive/bin data. `retainTileRegions` prunes pages outside the desired set. The largest empirically verified step is 1,000 m. Work follows the destination's entering tile set; once the old and new views are disjoint, its page count stays bounded by the active view as travel distance increases. Keys outside Core's signed 32-bit voxel range are rejected with `tile region coordinate is out of range` before page construction. The earlier L7 32 m / 160-million-node failure was the same unbounded region geometry.

## Shape readiness
|
||||
|
||||
`isTileShapeFree` accepts only LOD0 tiles whose padded mesh box maps to one valid SurfaceWorld plan, excludes FloatingIslands, plan features, routes, passages, edits, and overlaps with owner shape primitives or detail bounds. This covers the MC skirt and sample margin. Higher LODs are conservatively shape-dependent; the accepted path cannot use far parents. The native-only context is initialized without building sign arrays, proxies, owner primitive vectors, or spatial bins. Native sampling and classification paths check the padded bounds, reject unsupported fallbacks, and count any attempted shape-dependent read; tile generation then fails instead of returning a partial mesh.
|
||||
|
||||
The SurfaceWorld spawn view proved 27/27 near-ring tiles shape-free. A deliberately mis-marked distant tile `(0,0,100000,lod0)` reached the sampler and was rejected by the guard. After shape publication, native-only and full-shape generation matched all four hashes for all 27 tiles. Shape-dependent tiles waited for the release-published shape; tile jobs continue through the existing Epoch and MPSC result path, and published shape/page data is immutable. The FloatingIslands spawn proof accepted 0/27 tiles, so all waited for its shape. Slow-shape delay defaults to zero; audit and negative-control work is opt-in.
|
||||
|
||||
## No-hash timing pairs
|
||||
|
||||
Five interleaved W12 pairs, camera `0,-35,-487.94`, seed 0, Clang `-ffp-contract=off`, hashing off. Times are from process start. The L9 executable does not emit a first-tile completion event and starts tile workers only after shape compilation; its first-tile cell is therefore unavailable.

|
||||
|
||||
## Failed and retried runs
|
||||
|
||||
- The 24 m reproduction failed with `std::bad_alloc` under both address-space caps (`l11-cross24-as6g.log`, `l11-cross24-as16g.log`); the allocation trace above isolated the oversized bin resize. Final-binary 24 m, 32 m, and 1,000 m reruns passed (`l11-final-cross-24m.log`, `l11-final-cross-32m.log`, `l11-final-cross-1000m.log`).
|
||||
- The first readiness proof admitted 512 LOD0 keys (`l11-readiness-audit.log`, `l11-readiness-audit2.log`). Although the 27 near-ring equivalence check passed, distant owner-shape tiles changed the whole-view density hash. Tightening the proof to test owner primitive bounds reduced early admission to the 27 safe near-ring tiles and restored every hash (`l11-readiness-audit-final.log`).
|
||||
- One rebuilt audit invocation omitted the owner JSON path and exited 2 before generation (`l11-readiness-audit-path-error.log`; `Standalone/bin/data/owner_world.json` was missing). It was rerun with `Standalone/data/owner_world.json` and passed.
|
||||
- The required hash matrix and five timing pairs had no failed runs. All monitored run processes stayed below the 6,000,000,000-byte RSS ceiling; governor remained `powersave`.
|
||||
|
||||
The standalone Core/headless builds passed with Clang and GCC. The Unreal adapter change was source-reviewed but could not be built here because UnrealBuildTool/UnrealEditor are not installed on this Linux machine.
|
||||
|
||||
At spawn on SurfaceWorld, the near ring is ready at a 170 ms median versus 353 ms on L9, and the first L11 tile is ready at 153 ms median before shape publication; L9 gates tile work on shape compilation and does not report that milestone. For fast movement, destination-page work stays bounded through the tested 1 km crossing, while invalid Core coordinates return an error before allocation.

## Orchestrator review (Claude)
|

|

- **Re-run by me, 5 interleaved W12 pairs, no hashing.** Near ring (`neighborhood_ready`) L9
|

|
||||
−53%). Whole view 1.337 → 1.365 s median (+2.1%, 4 of 5 pairs slower): a small cost, accepted for a
|
||||
2× faster spawn ring. W12 hash runs give density `c10697a8f48380c7`.
|
||||
- **Crossings re-run by me on L11** (`--region-crossing --camera-step=S,0,0`): 24 m gives 432 tiles,
|
||||
0.867 s wall, 10.05 worker-s, rc 0; 1,000 m gives 2,260 tiles, 5.90 s wall, 70.4 worker-s, rc 0. The L9
|
||||
binary lacks the option, so the original crash rests on Luna's reproduction and allocation trace.
|
||||
- **New finding, for L12:** the 24 m crossing costs ~23 ms of work per tile, against ~2 ms for L10's 16 m
|
||||
crossing (288 tiles, 0.633 worker-s). Tiles outside the base shape bounds, served from analytic
|
||||
region pages, look about 10× more expensive. That is a moving-player cost.
|
||||
- **Concurrency read:** `World::compile` builds the shape privately, then sets `impl_->shape` and
|
||||
`buildRequest` before a release store of `shapeReady`. Every shape reader acquire-checks
|
||||
`shapeReady` first (short-circuit), and shape-free tiles use a private native-only context. Sound.
|
||||
- **Unreal:** `Source/VoxelForge/Private/VoxelWorld.cpp` changed (compile outside the writer lock;
|
||||
proven shape-free tiles start before `bReady`). It is NOT compiled here, so it must be built on the
|
||||
owner's PC before it is trusted in game.

Governor stayed `powersave`. Builds and runs used CPUs 0–11, at most 12 jobs, a 6 GiB address-space cap, and RSS monitors. Clang and GCC builds passed; peak sampled RSS was 881 MiB for one GCC compiler process and 679 MiB for the 1 km crossing. The GCC build process group peaked at 4.35 GiB. No Unreal adapter files changed.
|
||||
|
||||
## LOD cost and change
|
||||
|
||||
The 24 m profile is like-for-like at LOD1 in the same SurfaceWorld crossing. L11 generated 160 LOD1 tiles: 32 base-shape tiles averaged 2.73 ms each, while 128 analytic-page tiles averaged 71.72 ms. Of the LOD1 worker time, 9.06 of 9.27 seconds went to the marching-cubes density grid; the page compiler added 15 ms and built no packed lattice nodes. The page route lacked the manifest input needed for the exact LOD1 block proofs. Across all 160 LOD1 tiles, the sample counter reported 5.64 million density samples, or 35,271 per tile.
|
||||
|
||||
Analytic pages now retain the immutable shared manifest for block classification while continuing to sample the legacy density field. The proof audit checked 27,479 blocks and 36,574,549 samples, with zero violations. On the plain 24 m profile, page-backed LOD1 fell to 5.60 ms per tile; all 160 LOD1 tiles reported 432,000 samples (2,700 per tile) and 435 ms in density-grid work. Base LOD1 tiles averaged 2.51 ms, so page tiles are now about 2.2× their base cost. No base-shape bounds changed; pages remain privately built, immutably published, and bounded, with 16 pages at 24/32 m and 72 at 1 km.
|
||||
|
||||
## Plain W12 crossings
|
||||
|
||||
Worker time is the sum across tile workers; per-tile values use that sum. L11 values are from the L11 executable and logs. L12 values include region compilation in wall time.
|
||||
|
||||
| Step | Tiles | L11 wall / worker-s / ms per tile | L12 wall / worker-s / ms per tile |
|
||||
|---:|---:|---:|---:|
|
||||
| 8 m | 144 | 0.038 s / 0.381 / 2.65 | 0.035 s / 0.360 / 2.50 |
|
||||
| 16 m | 288 | 0.831 s / 9.476 / 32.90 | 0.125 s / 1.096 / 3.80 |
|
||||
| 24 m | 432 | 0.869 s / 9.912 / 22.95 | 0.164 s / 1.596 / 3.69 |
|
||||
| 32 m | 576 | 0.898 s / 10.261 / 17.81 | 0.172 s / 1.691 / 2.94 |
|
||||
| 1 km | 2,260 | 5.892 s / 69.534 / 30.77 | 1.247 s / 14.003 / 6.20 |
|
||||
|
||||
All five L12 steps passed; peak crossing RSS was 679 MiB. The 8 m L11 comparison is `l12-baseline-8m-page.log`; 16 m is `l12-baseline-16m-page.log`; 24 m, 32 m, and 1 km are the L11 final crossing logs.
|
||||
|
||||
## Spawn and hashes
|
||||
|
||||
Three plain W12 spawn runs had medians of 146 ms first tile, 161 ms near ring, and 1.361 s whole view. L11 medians were 153 ms, 170 ms, and 1.447 s.
|
||||
|
||||
All 28 requested L1 hash configurations matched L11: SurfaceWorld and FloatingIslands seed 0, Clang `-ffp-contract=off` and GCC default, W1/W8/W12, with five W12 repeats. Every run matched all 12 rows: full detail, whole view, nine LODs, and exact queries. Clang/GCC full-detail and whole-view D/M/P/T plus exact-query values are unchanged from the L11 report. The L3 FP-contract preamble/self-test remains in place.
|
||||
|
||||
| Recipe | Full-detail density / mesh / payload / topology | Whole-view density / mesh / payload / topology | Exact density+unclamped / detail / collision |
|
||||
|---|---|---|---|
|
||||
| SurfaceWorld | `0x0ee0579bd15cbbe4` / `0x32e5d4964d610fee` / `0x1932b96ee4b1d910` / `0x69743c6bad3447dc` | `0xc10697a8f48380c7` / `0xe75c9119a1498cd5` / `0x49a9a8d1835a6c8c` / `0xedcb23288b5e8724` | `0xe4d4a8eb95b35933` / `0xefcba20c0c70c415` / `0xe604823a249029bf` |
|
||||
| FloatingIslands | `0x6d842d2878b08ef6` / `0x4b868a3184f08035` / `0x2cedf2236788752d` / `0xeac17d5e0cb5044a` | `0x5be4d8cde79b2a76` / `0x96f75041f6861b3a` / `0x3700a516cc89d50c` / `0x6b99948d6eab4f21` | `0x61daded9c303becb` / `0xefcba20c0c70c415` / `0x84d37463be9b0573` |
|
||||
|
||||
The 24 m crossing hash also matches L11 at W1 and W12 (432 rows each): density `0x174588abdc8c0d2c`, mesh `0x4c401e27d9d05dea`, payload `0xeb10d9801c5ef125`, topology `0xf59d12304d0dcb4a`.
|
||||
|
||||
The route-verified base/page audit does **not** pass the requested exact-tile invariant. For `(0,-5,-31,lod1)`, the base density hash is `0xe0672dae7528f8d7` and page density hash is `0x882280f67bfddd77`; mesh, payload, and topology match. All 48 base-covered LOD1 candidates had density mismatches; 10 also differed in mesh/payload/topology. Across eight route-verified LOD0/LOD1 pairs, all eight density hashes differed. The base SurfaceWorld route uses manifest density while L11 pages use the legacy density evaluator; switching page samples to the base field would change the L11 crossing hashes. I kept the legacy page field to preserve the required crossing output, so this pre-existing parity conflict remains unresolved.
|
||||
|
||||
## Failed and retried runs
|
||||
|
||||
- An attempted 24 m base-shape expansion exited 2 at the 160-million-node bound (`l12-baseline-24m-base.log`). A separate per-tile native-only proof promotion failed with `region OOM` and was reverted (`l12-probe-cross24-profile-w12.log`).
|
||||
- The first plain step command passed `32` as the camera distance while labeling it 8 m; output identified it as 32 m. It was retained as the 32 m result, and 8 m was rerun with the correct distance.
|
||||
- The first FloatingIslands matrix omitted `--auto-surface-camera`, so it hashed the wrong 2,553-tile view. It was rerun with the L11 seed-0 island placement; all 28 corrected matrix configurations passed. The comparison helper also needed two small script fixes before it reported the final 28/28 result.
|
||||
- One base/page audit initially treated a LOD2 base-route fallback (`page_keys=0`) as a match. The audit now verifies the generated route; that apparent pass was rejected and the route-verified parity failure above is the final result.
|
||||
|
||||
Walking into new ground should feel much better: the plain 24 m crossing fell from 0.869 s to 0.164 s, and the 1 km crossing from 5.892 s to 1.247 s. Page-backed LOD1 tiles are down from 71.7 to 5.6 ms each while the L11 crossing hashes stay exact; base/page density-hash parity remains a separate unresolved constraint.
|
||||
|
||||
## Orchestrator review (Claude)
|
||||
|
||||
- Re-run by me (W12, no hashing, 3 interleaved pairs): 24 m crossing L11 0.874/0.914/0.898 s vs L12
|
||||
0.154/0.166/0.166 s (median 0.898 → 0.166 s, 5.4×). Spawn is unchanged (near ring 0.160–0.184 s).
|
||||
The 24 m crossing hash (density `0x174588abdc8c0d2c`, mesh `0x4c401e27d9d05dea`) matches L11 at W1
|
||||
and W12. Hash runs refill skipped samples, so time crossings with hashing off.
|
||||
- **Soundness of page-tile skipping:** the proof audit figures (27,479 blocks / 36,574,549 samples)
|
||||
are the base-shape audit from L9, not page tiles. The evidence for pages is the crossing hash
|
||||
equalling L11 (which filled every sample). That is necessary but narrow: one crossing, one seed.
|
||||
- ⚠️ **Route-dependent output (a pre-existing multiplayer bug, now measured):** the same tile key
|
||||
gives different density from the base shape (manifest field) than from an analytic page (legacy
|
||||
field). All 48 base-covered LOD1 candidates differed in density, 10 also in mesh/payload/topology.
|
||||
A tile's geometry then depends on streaming history (spawned near it vs walked to it), which
|
||||
breaks peer determinism. Top priority for L13.

# VoxelForge M3 Linux13 — route-invariant density
|
||||
|
||||
## Field decision and fix
|
||||
|
||||
The approved reference is the Core base shape built from the reviewed owner manifest: `Heightfield2D`
|
||||
for SurfaceWorld and `FloatingIslandFieldV1` for FloatingIslands. L12's base route sampled that
|
||||
field. Its analytic pages instead fell through to the copied legacy owner `GetDensityAt` evaluator,
|
||||
so the same key could sample different values after the player crossed into a page. In the L12
|
||||
SurfaceWorld audit, all 48 base-covered LOD1 candidates had different density; 10 also differed in
|
||||
mesh, payload, and topology. A 214,375-sample L12 negative-control run measured max/mean density
|
||||
delta `0.076171875 / 0.0133467594`, 29 sign changes, 170 edge-crossing changes, and up to 1.7778
|
||||
voxels of surface displacement. The manifest field is the approved Core world and is the reference
|
||||
kept here.
|
||||
|
||||
Changing the page manifest flag alone did not fix FloatingIslands: 8/8 page pairs still failed,
|
||||
with max density delta `433.925781`, 262,676 sign changes, and 17,188 edge-crossing changes across
|
||||
343,000 samples. The source fix binds each compiled page to its world's base `FStandaloneShapeWorld`
|
||||
before publication. Page density, lattice, detail, classification, and solid queries now delegate
|
||||
to that one evaluator; the legacy page-local evaluator is no longer an independent output route.
|
||||
`WorldAssemblyEvaluatorVersion` is bumped from 5 to 6.
|
||||
|
||||
## Route parity
|
||||
|
||||
The L12 evaluator-v5 negative control fails as required: 5/5 selected base/page pairs mismatch. After the fix,
|
||||
four audits passed: SurfaceWorld seeds 0, 1, and 17, plus FloatingIslands seed 0.
|
||||
|
||||
| Compared routes | Pairs | Mismatches |
|
||||
|---|---:|---:|
|
||||
| Base vs page (28 clipmap-requested pages; 26 base-covered page controls) | 54 | 0 |
|
||||
| Base vs native-only shape-free route (SurfaceWorld LOD0) | 27 | 0 |
|
||||
| Edited base vs edited page | 4 | 0 |
|
||||
| Same key built in initial and moved-world history | 2 | 0 |
|
||||
| Tile samples vs exact Core queries at LOD2–8 | 56 | 0 |
|
||||
|
||||
All 87 tile-generation pairs match density, mesh, payload, and topology hashes. The 56 higher-LOD
|
||||
pairs compare the sampled tile lattice to direct `densityAt` / `densityAtLattice` queries; these
|
||||
also match all sampled densities and solid/air signs. The owner fixture has
|
||||
`full_res_clip_levels=2`, so analytic page routes exist only at LOD0–1. In total, page comparisons
|
||||
covered 2,315,250 density samples with zero delta, sign, edge-crossing, or surface-root differences;
|
||||
6,172,229 exact-query samples had zero mismatches. The audit exits nonzero on any output-hash,
|
||||
sample, route-verification, exact-query, or proof-violation mismatch.
|
||||
|
||||
The history probe builds the same LOD0 key in a second Core world after a 96 m camera move. Both
|
||||
SurfaceWorld and FloatingIslands match all four hashes across those two build histories. The edit
|
||||
probe applies a sequence-1 density offset centered on a sampled sign crossing; it changes the field,
|
||||
and edited base/page results still match.
|
||||
|
||||
### Page proof audit
|
||||
|
||||
The fill-and-check audit generated page tiles with full density capture and uniform-block proof
|
||||
verification, so it checked the field those pages actually sample. Across the four audits it checked
|
||||
1,274 blocks / 1,695,694 samples: 518 blocks used the exact fallback, 6 were unknown, and there were
|
||||
zero false proofs or violations. SurfaceWorld walkability passed 5,642/5,642, 6,080/6,080, and
|
||||
4,785/4,785 samples for seeds 0, 1, and 17; FloatingIslands passed 4,000/4,000. Shape readiness
|
||||
passed 27/27 near-ring tiles where eligible. FloatingIslands has no eligible native-only tiles.

||||

All 28 required configurations passed: SurfaceWorld and FloatingIslands seed 0; Clang
|

`-ffp-contract=off` and GCC default; W1/W8/W12, with five W12 repeats per compiler and recipe. Each

|
||||
|
||||
The crossing output changes as intended. The 24 m W1 and W12 moved-tile hashes match each other:
|
||||
`0x337ca62131576728 / 0x7612f48e2ddbbaab / 0x69a67ed4add83b87 / 0xf11ac1ebd0f7ddb8` (D/M/P/T),
|
||||
replacing L12's `0x174588abdc8c0d2c / 0x4c401e27d9d05dea / 0xeb10d9801c5ef125 / 0xf59d12304d0dcb4a`.
|
||||
|
||||
The L3 FP-contract preamble and runtime self-test, L4 `FLazy`, L7 shared column cache, L9/L12
|
||||
proofs, and L11 native-only readiness/crash fixes were preserved. The L6 screen-space controls
|
||||
still pass their six same-LOD checks and reject the missing/floating-surface, global-octave, and
|
||||
stride-2 negative controls as required. Its whole gate still rejects the known far-field error over
|
||||
the 1 px bound (exit 6); the route binding does not affect those LOD3–8 base-field comparisons.
|
||||
The asynchronous MPSC/Epoch path and `ARCHITECTURE.md` §8.10 invariants are unchanged. No Unreal
|
||||
adapter files were touched; the Core exact-query and collision-sign routes were checked, but Unreal
|
||||
collision cooking was not built here. `ARCHITECTURE.md` §8.36 and `CODEMAP.md` §3.22 document the new
|
||||
route law.
|
||||
|
||||
Builds and runs used CPUs 0–11, at most 12 workers, a 6 GiB address-space cap, and a 6,000,000,000
|
||||
byte RSS monitor. The governor remained `powersave`. Peak sampled RSS was 904 MiB across runs
|
||||
(673 MiB in the no-hash cost table); the GCC build process group peaked at 4.27 GiB. Clang and GCC
|
||||
builds passed. No system changes or Unreal builds were made.
|
||||
|
||||
## Failed and retried runs
|
||||
|
||||
- `l13-route-baseline-s0-w12.log` exited 2 because the inferred binary-relative owner JSON path did
|
||||
not exist; reruns used the explicit repository JSON. The first baseline capture used the wrong
|
||||
camera, then an audit pass had empty proof-skipped density captures; the final L12 negative
|
||||
control is `l13-route-baseline-s0-w12-r4.log`.
|
||||
- `l13-route-fi-diagnostic.log` and `l13-route-fi-diagnostic-r2.log` intentionally exposed the
|
||||
remaining FloatingIslands split before the shared-source binding; both exit 9 on 8/8 mismatches.
|
||||
- `l13-route-edit-s0.log` exited 9 because its brush did not change the selected tile. Centering the
|
||||
brush on a sampled sign crossing fixed the audit in `l13-route-edit-s0-r2.log`.
|
||||
- `l13-route-history-sw-s0.log` exited 9 because the second-world probe exceeded the 4,096-node
|
||||
region compiler envelope. The retry compiles one matching LOD0 anchor tile and passes.
|
||||
- The first `l13-cost-*` measurements omitted `--force-generate` and used the owner JSON start;
|
||||
those are not used above. The final crossing and spawn runs use L12's camera and force-generation
|
||||
setting. The screen-space run's exit 6 is its expected far-field rejection, not a retried run.
|
||||
- All final builds, the 28 hash runs, eight no-hash cost runs, and two crossing-hash runs completed
|
||||
within their limits. No commit, push, or stash was made.
|
||||
|
||||
## Multiplayer note for the owner
|
||||
|
||||
Peers with the same manifest, seed, evaluator version 6, and tile key now reconstruct the same Core
|
||||
density and tile output through each available base, page, or native-only route, regardless of
|
||||
arrival history; terrain geometry still does not need to cross the network. Player edits remain an
|
||||
explicit versioned diff that must be ordered and synchronized between peers.

## Orchestrator review (Claude)

|
||||
+1.1%, within noise); near ring 0.168 → 0.171 s. The +10% in the cost table above compares L13 runs
|
||||
with L12 numbers from another session; interleaved, there is no measurable spawn regression.
|
||||
- The fix is structural: pages are bound to their world's single base `FStandaloneShapeWorld`
|
||||
evaluator before publication, so routes can't diverge by construction. The negative control fails
|
||||
on L12 (5/5), and the 87 tile pairs, 56 exact-query pairs and 2.3M page samples show 0 mismatches
|
||||
after. The page lifetime is safe because the base shape is owned by the `World` and outlives its pages.
|
||||
- Crossing output changed, as intended (evaluator version 5 → 6); the spawn and island worlds are

unchanged.

MC and refinement column-compute / non-column times (ms) were L4 `221/472` MC and `281/385`
|
||||
ground/cap; L5 `199/135` MC and `209/705` ground/cap; L6 `196/90` MC and `205/474` ground/cap;
|
||||
L7 `184/59` MC and `211/514` ground/cap; L8 `413/374` MC and `195/783` ground/cap. The column
|
||||
compute column overlaps those column portions. Timers are worker sums and may differ by a few ms
|
||||
from their subphase sums.
|
||||
|
||||
Stratum shells made zero field calls at LOD4–8 and took under 0.03 ms total. The profiler run
|
||||
measured about 1.408 s whole-view-ready; the unprofiled interleaved runs below are the timing result.
|
||||
|
||||
## Connector-shell repair
|
||||
|
||||
`AppendFarConnectorShells` is guarded to LOD6 and above. Coarse marching cubes can leave gaps in a
|
||||
route connector wall, so the repair checks four axial rays at connector stations and adds only the
|
||||
panels where the nearest coarse-mesh hit misses the source-field radius tolerance. LOD6 checks at
|
||||
128-voxel stations; LOD7–8 use 256-voxel stations. Only LOD6 had repair candidates in this spawn
|
||||
view: 5,066 triangles were added. The shell took 1.403 worker-s, including 1.193 s of column
|
||||
evaluation (about 0.210 s shell work outside those evaluations).
|
||||
|
||||
The LOD6 repair made 251,475 source/column calls: 44,596 worker-local hits, 206,879 local misses,
|
||||
30 shared-cache hits, and 206,849 formula evaluations. Thus 82.3% of calls evaluated a formula;
|
||||
the work is mostly uncached. A cache miss can include a point evicted by the four-way worker cache,
|
||||
so these counters do not prove every evaluated XY is unique. The L13-bound base evaluator already
|
||||
feeds the shared exact-XY cache; neighboring LOD samples mostly use different XY coordinates, and
|
||||
only 30 repair samples hit the shared cache. Reducing stations or rays would change the repair
|
||||
geometry, and no bit-identical reduction was proved.
|
||||
|
||||
## Ground and cap refinement
|
||||
|
||||
Ground refinement starts at LOD5 (32-voxel grid there, 64 at LOD6, then 128 at LOD7–8). Cap
|
||||
refinement starts at LOD4 (16-voxel grid there, then 128 at LOD5–7; LOD8 may use its configured
|
||||
interior override). Both query exact `Heightfield2D` columns and use those values for heights,
|
||||
normals, materials, clipping, and replacing nearby coarse faces. The existing shared cache is keyed
|
||||
by recipe/plan and exact XY, so aligned samples can already be reused across tiles and levels. The
|
||||
LOD-wide shared-hit counts are in the table above; they are not refinement-only counts.
|
||||
|
||||
Current safe skips are the plan Z-range check for ground and the cap-height-bound check for caps.
|
||||
No additional tile/cell skip was shown to preserve every sample that affects output; a grid point
|
||||
can also supply a neighboring normal or clipped cell. No new refinement sharing or skip was built.
|
||||
|
||||
## Ranked exact-output work
|
||||
|
||||
No exact-output change with a measured saving above 3% was proved, so no geometry optimization was
|
||||
built. The ranked work buckets are:
|
||||
|
||||
1. Ground/cap refinement across LOD4–8: about 3.95 worker-s including its column work. Removing all
|
||||
of it would be an unrealistic idealized 23% of 1.419 s at 12-way division; the sampled values
|
||||
currently affect geometry/materials/normals.
|
||||
2. LOD6 connector repair: 1.403 worker-s inclusive, an idealized upper bound near 8.2% at 12-way
|
||||
division. Most calls are uncached, and the missing panels are required for the current mesh.
|
||||
3. Far-LOD column formula work: 3.53 worker-s across LOD4–8, overlapping the two buckets above.
|
||||
Exact-XY sharing is already active; no redundant set large enough to remove was demonstrated.
|
||||
4. Marching-cubes non-column work is 1.13 worker-s and skirts 0.93 worker-s. Assembly is only
|
||||
0.017 worker-s; stratum shells are negligible. No exact reduction was established.
|
||||
|
||||
These idealized conversions divide worker-s by 12 and are not predicted wall-time gains. The L6
|
||||
screen-space gate was not used because this round made no geometry change.
|
||||
|
||||
## Interleaved cost, builds, and hashes
|
||||
|
||||
Five hashing-off W12 pairs ran in one session, alternating
|
||||
`Standalone/bin/linux/VoxelForgeCoreHeadless-linux13-clang` and
|
||||
`Standalone/bin/linux/VoxelForgeCoreHeadless-linux14-clang`. Every run generated 2,553 tiles at
|
||||
seed 0 and camera `0,-35,-487.94,0,-22`.
|
||||
|
||||
| Pair | L13 whole-view-ready (s) | L14 whole-view-ready (s) |
|
||||
|---:|---:|---:|
|
||||
| 1 | 1.416 | 1.410 |
|
||||
| 2 | 1.436 | 1.388 |
|
||||
| 3 | 1.416 | 1.424 |
|
||||
| 4 | 1.429 | 1.419 |
|
||||
| 5 | 1.430 | 1.426 |
|
||||
|
||||
Median was 1.429 s before and 1.419 s after (−0.7%, within this run spread). The telemetry is
|
||||
opt-in; the plain run shows no measurable cost when off.
|
||||
|
||||
Final binaries `Standalone/bin/linux/VoxelForgeCoreHeadless-linux14-clang` and
|
||||
`Standalone/bin/linux/VoxelForgeCoreHeadless-linux14-gcc` were rebuilt with `Standalone/BuildLinux.sh`,
|
||||
`-j12`, CPUs 0–11, and a 6 GiB address-space cap: Clang 19 with FP contraction off and GCC 14 with
|
||||
default contraction. Builds passed. Runtime peak RSS was 926,520 KiB; largest individual
|
||||
build-process RSS was 901,968 KiB (GCC), with a 4,557,196 KiB process-group peak. Governor remained
|
||||
`powersave`.
|
||||
|
||||
The final hash matrix passed 28/28: SurfaceWorld seed 0 and FloatingIslands seed 0, Clang/GCC,
|
||||
W1/W8/W12, with five W12 repeats per recipe/compiler. Full-detail, whole-view, all nine per-LOD,
|
||||
and exact-query rows match L13 exactly. Route parity also passed for SurfaceWorld seeds 0,
|
||||
1, and 17 and FloatingIslands seed 0: page/native-only routes, edits, history, higher-LOD exact
|
||||
queries, and proof checks had zero mismatches. The final 24 m crossing hash matched at W1/W12 on
|
||||
both compilers: `0x337ca62131576728 / 0x7612f48e2ddbbaab / 0x69a67ed4add83b87 / 0xf11ac1ebd0f7ddb8`

Hash logs and the 28-row comparator are in `Saved/Linux/l14-final-hash-*.log` and
|

|

crossing and pair logs use the `l14-final-crossing-*` and `l14-final-cost-*` names.
|
||||
|
||||
## Failed or retried runs
|
||||
|
||||
- The first SurfaceWorld hash matrix and first crossing checks omitted the spawn camera and used the
|
||||
headless origin. Their comparisons differed from L13; all 14 SurfaceWorld configurations and all
|
||||
four crossing configurations were rerun with the spawn camera and passed. FloatingIslands used
|
||||
its auto-surface camera and matched on the first run.
|
||||
- The first route probes also used the wrong camera selection. A later seed-1 probe used the fixed
|
||||
seed-0 camera, exited 9 on two LOD2 exact-query checks, and was rerun with `--auto-surface-camera`;
|
||||
the corrected seed-1 and seed-17 audits passed. The origin-camera route probes returned success
|
||||
but were not used as reference results.
|
||||
- Clang was rebuilt after the connector counters were added and again after folding aggregation
|
||||
into the existing opt-in guard. Both Clang builds and the final GCC build succeeded. No run hit
|
||||
the RSS, 15-minute stuck-step, or 30-minute limits.
|
||||
|
||||
Owner note: the highest measured far cost is still LOD6 connector repair, but its formula work is
|
||||
mostly uncached and its panels preserve the coarse route wall. The final interleaved plain runs show
|
||||
no measurable diagnostic overhead; no geometry change or L6 budget claim is made.
|
||||
|
||||
## Orchestrator review (Claude)
|
||||
|
||||
- Accepted as a counting round. Interleaved W12, no hashing: L13 1.429 s vs L14 1.419 s median, so the
|
||||
opt-in counters cost nothing measurable when off; committed with the report.
|
||||
- Conclusion: exact-output far work has no remaining lever above 3%. The big buckets
|
||||
(ground/cap refinement ~3.95 worker-s, LOD6 connector repair ~1.40 worker-s) produce visible
|
||||
geometry. Further far savings need geometry changes, judged against today's same-LOD mesh within
|
||||
the owner's budget (1 px at 1440p, at the LOD's closest display distance, display only).

## Result
|
||||
|
||||
Null result. No far-mesh shortcut passed the full 1 px, shading, swap, and topology gates, so no
|
||||
recipe enables one by default. Evaluator version 6→7 adds the optional `far_display_mesh` declaration;
|
||||
omitting it keeps the L14 output path. The controls are in the shared Core layer and do not touch
|
||||
LOD0–2, exact queries, collision, edits, or server state.
|
||||
|
||||
Candidates measured:
|
||||
|
||||
- Refinement grid scale ×2 at LOD4, 5, 6, 7, and 8. The all-tile LOD4 and LOD5 runs reject; the
|
||||
remaining per-LOD probes exceed 1 px or change shading, and the LOD6–8 candidates worsen at
|
||||
least one adjacent swap.
|
||||
- Reusing connector station radii leaves geometry p99 at 1.07 px but reaches 15.23 px maximum;
|
||||
shading delta reaches 0.667 and the normal changes by 73.3°.
|
||||
- Coarsening refinement at LOD4–8 is the largest measured saving, but exceeds the display budget.
|
||||
Halving connector station density also saves time but opens gaps. Removing
|
||||
any one ray direction also opens gaps, and the removed-panel control finds 99 new holes.
|
||||
|
||||
## Screen-space gate
|
||||
|
||||
The gate samples 65×65 surface grids across all 1,145 displayed LOD3–8 tiles (5,208,134 samples;
|
||||
skirts excluded). Geometry is projected normal displacement against today's same-LOD mesh at its
|
||||
closest display distance, using 90° horizontal FOV and 2,560 px (0.000613592 rad/px). Shading delta
|
||||
is the maximum of fixed-light normalized Lambert change and material selector/blend-channel change;
|
||||
the limit is 1/255. Each number below is p50/p99/max. Exact-path baseline values are all zero.
|
||||
The gate rejects geometry max above 1 px, shading max above 1/255, any worse per-sample swap,
|
||||
missing surface, or new hole/crack/floater. Its own validation fails if S13, stride-2, missing
|
||||
surface, floating surface, missing fine-ring, or removed-panel controls are not rejected; the
|
||||
panel control must expose at least one new connector hole.

The station×2 LOD6 screen scan measures 0/2/813.571 px, shading 0/0/1, with 1,349 holes and 1,690

floaters. Its connector audit counts missing ray stations by stable tile/ray/station ID: holes 8→221
|
||||
(216 new), floating classifications 464→405 (111 new IDs). In the refine×2 all row above, the
|
||||
screen scan reports those all-tile holes, cracks, and floaters. Station×2 leaves all six selected-patch
|
||||
swap p50/p99/max rows at baseline values, including 6→5 at 0/9.754/70.340 px. All four ray directions are required:
|
||||
the four one-ray-removed
|
||||
controls create 1,008, 1,022, 1,171, and 1,158 new holes. The explicit panel-removal control creates
|
||||
99 new holes. The exact-path audit has zero new holes, cracks, or floating pieces; its raw connector
|
||||
audit counts remain 8 holes and 464 pre-existing floating classifications.
|
||||
|
||||
The LOD4×2 and LOD5×2 candidates also fail in isolation. Reusing station radii misses the LOD6
|
||||
geometry and shading limits. The four one-ray-removed masks add 1,008, 1,022, 1,171, and 1,158
|
||||
connector holes, respectively.
|
||||
|
||||
## Negative controls
|
||||
|
||||
- The S13 global-octave-drop and stride-2 column-interpolation controls are rejected at every LOD3–8.
|
||||
- Missing displayed surface, a floating surface, and missing fine-ring surface controls are rejected.
|
||||
- Removing connector panels is rejected with 99 new holes. The exact connector path has zero new
|
||||
station IDs classified as holes, cracks, or floaters.

recipe declaration are shared by all recipes. Builds and runs used CPUs 0–11, up to W12, normal
|
||||
priority, 6 GiB address-space limits, and the unchanged `powersave` governor. Peak RSS was 904,400 KB
|
||||
(GCC build); peak runtime RSS was 736,432 KB. No run exceeded the time or memory limits.

## Capture pairs
|
||||
|
||||
JPEGs are 1280×720 and each is under 74 KB. Before is L14; after is the rejected refinement×2
|
||||
candidate applied at LOD4–8.
|
||||
The L1 view uses `(0,-35,-487.94) m`, yaw 0°, pitch −22°. Horizon uses the same location at pitch −2°.
|
||||
The mesa frame aims from the L1 location at the L6 mesa band (`(-472,-1432,-463.151) m` in the
|
||||
gate) with yaw −161° and pitch 0.9°.

## Failed and retried runs
|
||||
|
||||
- The first Clang build wrapper exited 127 because `/usr/bin/time` is absent; the direct Clang
|
||||
`-ffp-contract=off` build succeeded. GCC 14 default also built successfully.
|
||||
- A later sequential-build monitor was interrupted after Clang completed and before its GCC step
|
||||
launched. Clang and GCC were rebuilt separately with the same compiler settings and 6 GiB cap.
|
||||
- The first hash matrix omitted `--seed=0` and was discarded. A second FloatingIslands matrix used
|
||||
the SurfaceWorld spawn camera; it was rerun with the L14 auto-surface camera. The corrected matrix
|
||||
passed all 28 configurations.
|
||||
- Initial SurfaceWorld route probes used no camera for seed 0 (the 2,370-tile bound), omitted
|
||||
`--region-crossing` for seed 0 (shape compiler safety bound), and used the fixed seed-0 camera for
|
||||
seed 1 (LOD2/exact-query parity mismatch; seed 17 was not run with that setup). They were rerun
|
||||
with L14's camera selection and region-crossing option; all four final route audits passed. The
|
||||
first 24 m crossing also omitted `--region-crossing` and exceeded the shape-build safety bound;
|
||||
all four corrected compiler/worker combinations passed.
|
||||
- The first connector audit compared aggregate counts. It was replaced with stable per-ray station
|
||||
ID comparison before the final gate. The initial L4 selected-tile gate missed a changed tile; the
|
||||
all-desired-tile coverage gate found and rejected it. The full-view gate is used in the table above.
|
||||
- The first JPEG encoding pass did not set CPU affinity or an address-space cap. All six files were
|
||||
re-encoded under CPUs 0–11 and the 6 GiB cap; sizes and pixels stayed the same.
|
||||
- The first five speed pairs included screen-gate color capture on ordinary streaming tiles. That
|
||||
diagnostic copy is now enabled only for gate runs; all five cost pairs were rerun and the table
|
||||
above uses only the final logs. The final exact gate passed and station×2 remained rejected.
|
||||
- No builds, captures, final audits, or cost runs timed out or breached their memory limits. The
|
||||
intentional candidate rejections are listed above, not treated as infrastructure failures.
|
||||
|
||||
Evidence logs are in `Saved/Linux`: the final baseline and station×2 all-tile gates are
|
||||
`l15-final-gatecolors-exact.log` and `l15-final-gatecolors-station2.log`; the best-payoff
|
||||
refinement×2 all-tile gate is `l15-final-gatecolors-refineall.log`. Single-LOD refinement coverage is in
|
||||
`l15-gate-alltiles-refine-l4x2.log` and `l15-gate-alltiles-refine-l5x2.log`. Single-LOD refinement
|
||||
and connector-ray probes are `l15-gate-refine-l{x}x2.log`, `l15-gate-reuse.log`, and
|
||||
`l15-gate-rays{14,13,11,7}.log`. Hash, route, and crossing evidence is in
|
||||
`l15-final-hash-audit.txt`, `l15-final-route-*.log`, and `l15-final-crossing-24m-*.log`; final
|
||||
station×2 speed pairs are `l15-final-speed-pair{1..5}-{before,after}.log`; refinement×2 pairs are
|
||||
`l15-final-speed-refineall-pair{1..5}-{before,after}.log`.
|
||||
|
||||
## Note for the owner
|
||||
|
||||
The default far terrain stays the same because every measured reduction exceeded the 1 px geometry
|
||||
or shading limit, worsened a swap, or opened holes. Refinement×2 across LOD4–8 saves 13.6% by the
|
||||
median whole-view ratio, but creates hundreds-pixel errors and visible gaps, so the captures show it
|
||||
for review only and it is not enabled.
|
||||
|
||||
## Orchestrator review (Claude)
|
||||
|
||||
- I looked at the LOD6 mesa-rim pair. After refine×2, the jagged crests are visibly smoothed, black
|
||||
holes appear in the cap/ceiling, and a dark sliver shows on the left horizon. That confirms the
|
||||
gate's rejection: the instrument is right this time, not the world.
|
||||
- **Not merged into `assembler/world`:** the candidate knobs and the evaluator 6→7 bump add no default
|
||||
output and would invalidate version stamps for nothing. The full L15 code (the extended gate with
|
||||
shading, swap and connector-ID audits, and the candidate controls) is kept on side branch
|
||||
`wip/l15-far-budget`. `assembler/world` stays at L14 code plus this report.
|
||||
- Conclusion of L14+L15: far terrain has no exact or within-budget saving left with today's design. The
|
||||
remaining far cost is the price of the current refinement and connector-repair geometry.
