- Export commandlet writes the live Core adapter's world_assembly + resolved layout pair;
the headless owner path imports that pair (manifest/layout equal, layout_chunk_width_q
validated). owner_world.json re-exported from the owner's staged assets on the Linux host.
- Adapter SW route: Core clearance/radius floors, 0.5 m support search, outward-facing
tie-break; passage mouth/mid radius floors match Core (36/24 owner voxels).
- FI in Unreal now uses the legacy (compiled analytic) generator unless a plan is imported:
the auto native-FI plan failed the passage audit on the owner plan (1843 blocked samples,
945 open-air violations). Owner decides whether native FI returns.
- In-engine spawn traces per strate (3 each): SW GenerateTile 42.7 worker-s vs 20.1 headless
for equal tile counts; LOD0 p95 45-169 ms in UE.
- Fast tier green; all three passages pass on the shared plan.

a 17x9 ray coverage probe aborts before rendering if tiles are missing (truncated-mesh

- Core caps each passage mouth reach to its own strate's usable content band (owner
DA_Strate1 exports ReachMax=5000 owner voxels, which put the SW->FI lower mouth 79.5 m
below FI, inside TN).
- Unreal adapter: SW route search keeps the old 64 m candidates first, then a bounded
single-mouth search with shorter lengths; logs candidate/rejection counts.
- Internal-chain passage floor/support tweaks (only with >2 strates): ripple 1-2 4.78->2.90 cm,
2-3 3.57->0.10 cm. Interfaces still 0/3 walkable (59/3/2 unsupported).
- verify.py: legacy tiers use Standalone/data/regression/owner_world_2strate_l61.json; new
four-strate stage reads its expectations from owner_world.json (currently red on interfaces).
- Unreal trace L14 vs HEAD, same assets (16-chunk FlatPlain): 12.20 vs 12.56 worker-s; no x2.

Linux UE builds failed on the Core wrapper module: the Linux-only PerModuleInline.gen.cpp saw Standalone/Compat
shadow headers instead of the engine's, and WITH_EDITOR was redefined under -Werror. Compat headers now forward
to the engine headers with include_next for generated Linux module TUs (canonical Core TUs opt into the Compat
definitions via CoreNamespacePreamble.h); CoreMinimal.h undefines WITH_EDITOR first. VoxelForgeCore.Build.cs
enables that forwarding and AVX2 on Linux only; VoxelForge.Build.cs disables Unity on Linux only. Portability:
std::int64_t consistently in VoxelContentManager.cpp; grouped &&/|| in VoxelRedefinedDensityField.cpp. Linux-only

The passage mouth fade multiplied the signed carve distance by zero, which turned native rock into an

uncarved field and the full signed carve. The FI style-0 route followed a lifted grade envelope over

Known open: final XY-column cache compiled in the owner build but is unverified;
island LOD0 p95 ~155 ms misses the 133 ms sprint deadline (legacy ~43 ms); the island
manifest only fits the BuildHost fixture layout (owner's world: Core init fails,
empty world) -> round 4 builds plans inside Unreal.

The round-3 'field contact error' measured hit-to-anchor distance; V2 contacts are 0 cm and on the zero
isosurface. Tagged-tile cost 5.7-6.7x -> 1.175-1.270x MC; organic 0.998x. Bound, shelf-thickness and route
audits rerun with negative controls; W1/W8/W16 stable; V1 and MarchingCubesV1 unchanged.

Owner saw content floating above native terrain, spiky triangles, reversed carve/fill and late relief.
Causes: shared mesher placed Core tiles on a 12.5 cm grid; content/atmosphere asked strate ranges in
12.5 cm voxels; Core edits add density where the legacy diff subtracts. Horizon LOD8 bridge edge
5.657 -> 2.265 cells. Relief mesh p95 60.8 -> 42.0 ms (LOD0). New BuildHost checks for scale, height,
blueprint carve/fill and per-kind streaming lag.

Manifest imported into UVoxelSettings (hash 8933693d9560ba9f), folded into the season
content hash only when Core is on. BuildHost: W1/W8/W16 stable, 2553 surface tiles match
standalone, 432 LOD transitions, collision on all 36 expected tiles. Matched timing
96.8 s native vs 197.3 s bridge (2.04x). Collision support tiles wait for Core region admission.

Luna, M1 round 1 of 4 (plan in Standalone/ASSEMBLER_M1_REPORT.md):
- Versioned fixed-scale world manifest (the shipped plan format) and the Core block
contract: point evaluation, interval-or-unknown, influence bound, detail envelope, channels.
- Interval audit: 256 boxes / 6,912 samples, 0 missed, 0 unknown; a deliberately false bound
is detected (negative control).
- Native Heightfield2D with biome input: 4,096-point hash fae2721c052aec5c identical at
W1/W8/W16; point queries 2.059 ms vs 62.115 ms legacy -- but NOT a match yet (mean density
error 274 voxels, 2,261 sign mismatches vs the legacy surface). 45 mesh-free Core queries
match direct evaluation exactly. Existing cave world unchanged (walkability, 64/64 tiles).
- Open: collision readiness, a valid full-view timing (viewer captures were occluded/empty;
top-down height maps are the only usable pair).
Also carries the design doc's owner decisions (fixed water; player edits unrestricted, route
law for automatic changes only) and three plugin files + BuildHost scripts that earlier round
commits had missed (also fixed on unreal/core-integration as 2574b56).

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).

Standalone/ (C++20, MSVC /O2 /arch:AVX2 /fp:precise, Build.ps1): copied density pipeline, op stack,
cave morphology, passages, strate manager/composer, noise, DetSinCos, mesher, clipmap selection,
with a UE compatibility layer (Compat/). Owner data exported once to Standalone/data/owner_world.json
by a default-off explore-commandlet exporter (the only plugin-source change). 25 cm voxels.
Parity: seed 0, 3,436 samples (strate edges, negative/far coords, rooms, tunnels, passages,
landings): bit-identical. Viewer: full 7-level clipmap, per-level toggles 1-7, T = round winding
tunnels (standalone option), N/P seed, F wireframe.
Timing NOT yet a baseline: 515 s for 12,054 tiles (L0 70 s, L6 296 s); the compat TMap/TSet are
vector-backed with linear lookup, which the plugin's caches do not expect.

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.

Stopped by low memory (another app at 14 GB; processes failed with 0xC0000142).
r6 (compiled and measured, owner playing during the run), step 2e -> step 2f r6:
crumbs < 1 m^3 (max per profile) 2,898 -> 3 FAIL (0,0,0,0,2,1,3,2)
flakes (shard share / p95 angle) 40.7% / 84.2 deg -> 2.1% / 33.1 deg pass
lattice-scale detail energy 0.832 -> 0.016 pass
grid signature (autocorrelation) 0.666 -> 0.349 pass
min solid share / roof openings 2.7%, 26,657 -> 79.2%, 0 pass
worst profile ring time 642.8 -> 636.3 ms FAIL (6 workers, 259^3)
Step 2e measured 642.8 ms here vs 570 ms idle earlier: the game was costing ~12% during this run.
Brick proofs + audit, seams + injected seam, 1 vs 6 worker determinism pass. After r6, feature
probabilities were lowered to remove the last crumbs: NOT compiled, NOT measured. TraversalSeeds,
in-game captures and the LOD-rejection figure for 2e are still to do. Reject screenshots included.

Editor-only, default off. Seeded chamber graph (jittered XY grid, spanning tree, optional loops,
tunnels, shafts, pillars, ledges, spires, floating masses, basins), 8 profiles, four detail bands
at every surface-affecting 25 cm sample, sound brick proofs. 259^3 ring, six workers, medians of 3:
404-570 ms (worst TerracedBasin 570.0 ms). Detail, seam, bound-audit (0 violations, undersized
control caught), determinism (1 vs 6 workers) and TraversalSeeds all pass; live tests untouched.
Not accepted yet: the profiles are 81-97% open air. In the slices a "TightNetwork" is a large void
with scattered solid blobs (rooms of 0.5-0.76 x pitch overlap and merge), and the finest detail
band shows as salt-and-pepper speckle with 22-109 separate 1 m components per ring: fast partly
because air bricks skip, and the look needs the owner's judgement. Also missing vs live: maze,
flat/plain, crystal-chamber, surface-world and underwater grammars; water geometry.

Stopped by low memory (another app held 12.5 GB; processes failed with 0xC0000142).
Editor-only, default off: a seeded connected room graph (varied chambers on a spanning network,
optional loops, shafts, rock features, ledges, basin floors), eight parameter profiles, the
step-2d brick driver and detail bands, a new test VoxelForge.ParameterizedGeneration.TraversalSeeds
(PASS in step2e_functional_01, which also proves the tree compiles). Existing live tests untouched.
Not yet run: the eight-profile ring benchmark, variety metrics, slices, detail/artefact/determinism
checks.
