Core.Lattice.PrimitiveField v1, opt-in per strate (legacy Maze/VerticalShaft stay legacy): resolves the real
arrival and departure mouths first, plans a mandatory spine, then maze cells and two dead ends (9 rooms,
9 edges, stable IDs). The spine descends 20 m through four helix turns (6 m radius, 3 m clear width, 5 m
pitch, 2.6 m clearance; max grade 10.0 deg); each feature is one filleted void (0.57 m measured). Final-field
reachability passes at 883 stations; an orphaned shaft control is rejected; exact intervals (0 misses) and
a whole-surface audit with 0 flags. Whole view 1.69 s (above the 1 s target). fast/medium/full PASS.

The walk tread was built per segment as a one-sided density clamp, so its crossing with the native
field moved at segment joins (L35: 2.25-2.48 cm washboard). Treads now overlap up to 2 m as bounded
signed-distance slabs (0.06 cm residual). The FI mouth's crater detail and tread met without a smooth
join; v23 filters the local field, drops thin isolated solids and smooth-unions the tread with the

StrateLayoutChunkSizeMeters (world setting, default 8 m; owner decision) is resolved once in

Luna, M1 round 4 (resumed after the night stop):
- Cliff: sub-voxel audit (29,929 half-voxel XY columns, min run 3.75 voxels, 0 subvoxel runs;
old taper control exposes 20,963) and a root-line shelf at the two-voxel minimum.
- Horizon slab = aliased LOD8 cap ceiling. The first fix hid the ceiling at LOD8 (challenged:
enclosed, interior-lit strates); now the LOD8 cap is rebuilt deterministically from the
native heightfield, skirts preserved; looking up and out shows the cap present.
- Routes: review manifest with 33 stable-ID route points + capsule/support constraints; capsule
sweep 0 blocked samples / 0 unsupported centres, negative control detected.
- Server path: World::densityAt answers without render meshes. Physics cooking not available
standalone.
- Hashes (evaluator + 2,226-tile stream) identical at W1/W8/W16. LOD8: 4.446 s for 529 tiles,
14.25 M field calls, 165 unknown tiles.
- Captures at 60 fps cap + vsync (owner's GPU coil whine). One cliff probe crossed the ~8 GB
guard (7.69 GiB) and was stopped before capturing.
My review: cap view matches legacy closely, no slab; native cliff is a clean attached ledge
(cleaner than legacy); a few small spikes on the ridge top.

Luna, integration round 3, from the owner's four in-game screenshots:
- Capsule rings at the opening and the shaft continuing through the cave room were Core
world defects: the synthetic bore is removed and the opening gets a finite origin room
and floor (solid below). New world version, W1/W8/W16 identical: density
a8bcb72d41092503, mesh 90f29ba15e24579f, payload 82c6b489e7bb7fd7, topology
7b99448a1f844f2c.
- B-side landing and surface: headless coverage found no missing tiles or LOD-transition
gaps (960 / 640 fine tiles compiled after travel); best explained by Core's missing
SurfaceWorld representation. Null-RHI cannot rule out a presentation-only issue.
- Core mode GetBiomeAtWorldLocation now answers (e.g. Biome_Surface_Plain); biome
terrain itself is not generated yet (proposal: native Core SurfaceWorld evaluator).
Owner checked the Step29 viewer himself: the surface strate type is absent there too.

Luna, integration round 1 (BuildHost only; owner's project and assets untouched):
- New runtime module VoxelForgeCore: one shim per Standalone/Core/core_sources.txt row
(sources stay canonical under Standalone/), NoPCH/no unity, manifest check; VoxelForge
links it (no runtime routing yet). UE link-safety audit: 18 shims, 83,843 symbol lines
vs 399 Unreal-style names, 0 clashes.
- Adapter (editor commandlet path) turns staged copies of the owner's DA_* assets into
schema-v1 JSON; with clip_radius=3/max_clip_level=8 it reproduces all four Core hashes
(0xdb2991c73215af4c, 0x8236c5edd7fc8e4f, 0x4c48fa75a543d58e, 0xbea22e76b34a4dfc) and
walkability 5,642/5,642 at worker limits 1, 8 and 16.
- Noted: the owner's settings asset says max clip level 6 (standalone used 8); Core uses
25 cm voxels vs the plugin runtime's 12.5 cm.
Not done yet: AVoxelWorld switch and Core runtime route (round 2).

Stopped by the owner's decision (in-game lit captures were eating the round); he judges the look in
game instead.
1. Fall-through with the research field: fixed. Deep drop, gate on: 2 holds (0.50 s), min foot
clearance +43 cm; gate off: penetrates (-278 cm). Stress fixture offsets converted to metres.
2. VOXEL_SIZE 25 -> 12.5 cm. Physical sizes kept in metres (player, steps, gate, insets, research
field sizes, dig radii, test thresholds); class defaults that count chunks/voxels doubled
(ClipRadius 6, RenderDistanceChunks 1536, ViewDistance*, StrateViewMargin 6,
PawnCollisionRadius 2, SkirtCells 4, EdgeSealThickness 128, decoration spacings, density volume
res 256). Asset values override these defaults: the owner must double his own.
Ring scale, six workers, idle, step-2f field before the look changes: 64 m cube (519^3) 4.55 s;
32 m cube (259^3) 0.95 s.
3. In game: tiles go through the brick evaluator (proved by a log marker); profile switch rebuilds
the loaded world (~5,800 tiles); full-detail fill 12.4 s after spawn in the visible-window test.
4. Look: round winding tunnels, per-column ellipsoid/lattice caches. All step-2f geometry gates pass
at 12.5 cm (0 crumbs, 1 solid component per profile, solid share 69-87%). 259^3 ring, six workers:
1.08-2.02 s (worst HyperComplex) -- the 600 ms gate FAILS. Lit captures failed (hidden/off-screen
window, then blank frames); not pursued.

- CODEMAP: data-flow diagram, §3.2b/§3.2d, generator and strate-manager
rows, test rows and §4.2/§5 now describe the stack-only path; the
deleted archetype functions, bUseOperatorStack and the Not Op Stack
stats are gone; line hints re-synced for VoxelGenerator.cpp,
VoxelStrateManager.cpp and VoxelStrateDefinition.h.
- ARCHITECTURE §8.1: archetype table lists stack builders; §8.10 surface
column and shaft cache entries name their current owners.
- REVIEW_FINDINGS: tick "Operator stack as the only density path"; add
the no-strate-manager fallback world as its own open item.
- fable-idea: T1.a status names the current column caches.

The single player-following water plane only uses the strate's
WaterMaterial; UVoxelBiomeDefinition::WaterMaterial is never read. The
design (§8.14 content profile) still lists it, so record the gap as an
open owner decision instead of silently dropping it.
