CPU uploads now bypass the 4-batch / 2 ms cap until the first resident view.
Luna's race (inside the Codex sandbox): CPU 1.354 s vs GPU 3.152 s, warm-up
queue 1.16-1.21 s on every launch. My runs outside the sandbox, same binary
(Step16FairRace, RunGpuFarViewer, interleaved): CPU 1.497 / 1.359 / 1.334 s;
GPU 3.088 (first launch of this build, warm-up 1,287 ms) / 1.262 / 1.260 s
(warm-up 3.2 / 3.1 ms). AMD DxCache was written at my GPU launches (08:46:57,
09:33:37) and never during Luna's runs: the sandbox cannot persist the driver
shader cache, which is why every one of Luna's launches paid the compile.
Audits: hashes, walk 5,642/5,642, 0 diffs vs CPU/WARP, survival 5.10 GB.

Timeline showed the post-export window was frame-paced: the 4-batch / 2 ms
per-frame upload budget held CPU-fallback tiles up to 755 ms after they
finished, and 35 GPU batches drained one per frame. Before the first whole
view, GPU work now drains as one batch and CPU fallback starts with GPU input
preparation (--gpu-far-no-cold-drain = paced control).
Luna's race: CPU 1.393 s vs GPU 1.677 s. My interleaved runs (Step15Timeline,
RunGpuFarViewer): GPU 2.902 (first launch) / 1.252 / 1.209 s; CPU 2.196 /
2.250 / 2.061 s. The CPU viewer still uses the paced upload budget at cold
start (stream 674 -> 2250 ms in my runs vs 741 -> 1422 in Luna's), so the
race is not yet fair. Audits: hashes, walk 5,642/5,642, 0 diffs vs CPU/WARP.

Per-kernel fences in the production viewer put 1.73-1.98 s on the near-detail
Flush (shader creation 17-19 ms, dispatch calls ~0): skipping only that
dispatch cut idle warm-up 1.893 -> 0.521 s. Near detail rewritten with a
shared owner-roughness loop and shared Perlin samples: DXBC 448,588 -> 120,860
bytes, cold first use 1,596 -> 709 ms. Warm-up median 1.052 s, yet whole view
is unchanged (CPU 1.352 s vs hybrid 3.196 s): after input export the hybrid
spends 1.78-2.00 s streaming 1,082 GPU + 1,144 CPU-fallback tiles.

Cold first-use per shader (queue ms): EvaluateFarField 1757, EmitNear 2429,
FarConnectorRings 784, FarSkirts 507+975; the far EmitCS dropped 2327 -> 3.2
by splitting out the near midpoint fallback into EmitNearCS. Warm-up under

Top-down A/B/A controls: dispatching the 11 real compute shaders once removes
the 1.3-1.7 s first GPU Present (resource creation alone does not); 1 worker
also removes it and 8 workers bring it back. Default --gpu-far now prewarms
shaders asynchronously during shape compile (--gpu-far-no-prewarm = control).
The warm-up queue itself takes ~2.75 s, so whole view is unchanged:

Re-verified f2de8fe (hashes, walk 5,642/5,642, far topology 0 diffs vs CPU and
WARP, GPU survival). The remote LOD3/4 band was a direct-GPU coverage loss
(overlapping pixels identical, surface pieces missing, e.g. (6,2,0,lod3));
LOD3/4 now mesh on CPU, root cause in the GPU route still unidentified.
A minimal first-submit repro (pools, first-touch dispatch, device flags) did
not reproduce the 2.4 s stall. Whole view: CPU 1.438 s vs GPU 4.704 s median.

Luna's session ended on an API "Bad Request" before a final report; state is
unverified by me. In the log: GPU clipped-skirt emitter (count/scan/emit,
protected signs and critical air honoured), exposed-skirt audit passing at
the end; first-present stall reproduced on every launch (2.36-2.59 s, not
exe identity/idle/CPU run) and hidden by holding the CPU-ready frame until
GPU residency. Remote LOD3-4 band still differs from CPU; draw ranges and the
one inspected LOD3 tile match, cause not yet found (one-tile probe mid-fix).

5,642/5,642, W1/W8 hashes 44/44, far topology 0 diffs vs CPU and WARP, far
survival PASS). Remote GPU holes were missing clipped LOD skirts: tiles with
visible skirt faces now fall back to the CPU mesh path, leaving only 16 far
tiles GPU-rendered until a GPU skirt emitter exists.
My interleaved runs (SkirtSeamVerify, process start -> whole view):
CPU 1.522/1.488/1.430 s; GPU 4.271/1.749/1.659 s. A ~2.8 s first Present

Near LOD0/1 (detail band, relief, root refinement, normals) now evaluated and
meshed on the GPU. 960 near tiles: zero sign/topology differences vs CPU and
WARP, vertex max 0.0049 mm (was 15 cm); far survival audit passes; CPU hashes
44/44 unchanged. Far connector-panel outlier (64.56 cm, LOD8) remains a
tessellation difference, and remote captures show missing far geometry on GPU.
Cold readiness (viewer clock, my interleaved runs): CPU 2.51/2.49/2.40 s,
GPU 5.05/2.68/2.80 s. The ~2.1 s Present stall hit only the first GPU launch.
Viewer spends ~1.13 s before shape compile starts (startup checks), which is

- Relief per wavelength band compared with the owner field; the 4-8 and 8-16 voxel bands were lost.
Restored within the partition-of-unity blend; max detail gradient 0.545 (limit 0.55).
- New owner-band gate: fails all six views on de14f00, passes all six now.
- W1/W8 44/44; path hash both directions; routes 5642/5642; stair-distance, ring, thin-sheet,
coarse-panel, far-survival audits pass; bad-shell control fails.
- Cold 1.127 s vs 1.108 s (within spread); nearest-tile readiness 12.20 vs 12.16 ms.
Caveats: the 143-ray GridStair normal audit is at 62.2% vs its 60% limit (was 76.9%); in the tunnel
capture the floor shows a regular dimple pattern, and the passage shaft close-up is still smooth.

gradient 0.323 voxel/voxel. High-detail patch scan 133 -> 0; exact midpoint edge roots kept
(removing them: 7,993 bad roots, 46 patches).
- Fins: exposed skirt triangle scan 1,776 -> 0; thin sheets 0; coarse off-surface panels 0.
- Path hash both directions equal; W1/W8 equal; routes 5642/5642; passage detail ratio 0.850;
far survival passes, bad-shell fails; 30-crossing flight: nearest tile 15.1 ms median, 124 ms max.
Caveats seen in the captures: the owner-ray wall has visibly less relief than before; the fin

Not verified as a whole. In the tree when Luna's session ended ("model at capacity"):
- fins: LOD seam skirts could hang into tunnel air; skirt triangles are now clipped against the solid
half-space and carry a per-face mask so a host can hide skirts between same-LOD neighbours.
- choppy LOD0 stairs: marching cubes' linear edge interpolation misplaced vertices where the relief
bends within one cell; edge crossings corrected with the exact field (82 patches, midpoint-edge
errors 18,818 -> 3,288); normal halo now ignores the +-4.125 fallback samples.
- an explicit unclamped Core distance query for audits.

- Core compiles exact-tile analytic slabs for entering tiles; a Z-column sampler reuses the coherent
noise context along each tile column; the viewer keeps residents and prioritises nearby tiles.
- 30-crossing straight flight: nearest tile ready 15.8 ms median / 27.6 ms max; full crossing wall
121 ms peak; worker CPU per crossing 545 ms median, 834 ms max.
- W1/W8 hashes equal; routes 5642/5642; look, passage, stair, thin-sheet, coarse-panel and far
audits pass; bad-shell control fails; path-hash audit kept.
Cold whole view, measured by me interleaved (busy machine): 1.242 s vs 1.255 s for 3b37d57, parity.
Still open from the owner (LOD0): fins along a strata seam, choppy stair facets.

From the owner's fly-through ("very impressive, in some cases slightly better than the original"):
- Streaming: Core compiles world-aligned fine-detail pages for tiles entering the view and releases
them when they leave; the viewer keeps resident tiles. One chunk crossing: 144 new tiles, 1,822
kept (was a full rebuild). A tile built as a late page hashes identically (density, mesh, payload,
topology) to the same tile from an initial build.
- LOD>=1 fins: off-surface planar connector panels are now checked against the source surface and
projected onto it; coarse audit 0 off-surface panels; far survival passes, bad-shell still fails.
- LOD0 stair patches: 2,630 sign-changing edges had one endpoint at the fixed +-4.125 fallback
(carve surfaces were excluded from distance storage); distances now completed analytically, 462
packed signs corrected; the audit now fails on any sign edge missing either endpoint (0 of 952,997).
- W1/W8 hashes equal; routes 5642/5642; look, passage and far audits pass.
Verified by me, interleaved (8 workers, cold): 1.014 s vs 1.008 s for aeeedaa, no regression.

- SHARED_CPP_LIBRARY_PLAN.md rewritten for a UBT module compiling the same sources via shims.
Open issue before Unreal: Core's implementation still compiles the Compat stand-ins named like
Unreal types (TArray, FVector...); inside a UE binary that is an ODR clash. Must be namespaced.

- AddLanding no longer adds a shallow positive ellipsoid (floor plate check 71.3% -> 0%).
- Round 10 had removed all relief on passage walls to pass the ring check (smooth tube; rejected).
Cause found instead: the owner roughness's 8-voxel Z anchors with linear interpolation. Passage-

in-view far connector (sections <=128 voxels, 4 radial rays) against the emitted mesh. Falsified:
removing one tile's shell triangles -> 16 missing, 16 holes, exit 14. Passes at LOD6/7/8.
- Far connectors follow source radial crossings; strata patches emitted at LOD7/8. Default LOD8.

neighbourhood mesh-ready 23 ms after streaming starts.
- The plugin's materials consume UV, the packed biome/slope/blend colours and the ceiling/ground
sections, so the viewer-only skips stay off by default (diagnostic only: 1.53 s without them).
- UVs staged as FVector2f (matches the game stream; -20 MB, no speed change). Far-bin reserve 24x.

- crater edit (sphere+box+capsule, one transaction across LOD0/1): 15-27 ms; player 3x3x3
neighbourhood meshes ready ~18 ms after streaming starts.
NOT yet verified (in the tree, unhashed): standalone-only skips of UV/colour arrays and of the

sheets 9 -> 0; the audit now also fails on isolated small components).
- Bounded 16-voxel floor/wall blend (18 rejected: it created a sub-voxel sheet), 3-voxel
strata/cave blend, C1 tunnel radius profile (0 radius/slope steps at joins).
- Surface relief: broad octave with amplitude modulation instead of uniform bumps.
- Cold, no cache: 64 m full detail 0.924 s (8 workers) / 0.715 s (16); whole view 2.016 / 1.605 s.
- 1-worker and 6-worker hashes match; 5,642/5,642 passage samples open.
Not solved: regular bands in the narrow passage shafts, a few slivers on tile boundaries, faint
wall/floor plates; close-view mean surface distance to the owner field got worse (see REPORT.md).

Luna's continuation stopped when Windows could not start new processes (0xC0000142, low memory).
Fixed-view join step: chamber 0.041, tunnel 0.434 (bar 0.450, barely). Routes 5642/5642 open.
Shape stages 0.963 s / 0.870 s. Floor join plates still visible; final checks not run.

The look round was stopped by the system for low memory (not a code fault) while
checking worker-independent hashes and refreshed owner-distance comparisons.
Saved state, not yet reviewed:
- passage floors carry rock detail (flat-floor check passes)
- tunnel radius step between joined segments 0.0000 voxels across 240 joins (was 2.9156)
- 3-octave surface relief
- cold 64 m full detail 0.982 s (0.703 shapes + 0.279 mesh), whole view 2.490 s, 8 workers
Pending: determinism 1 vs 6 workers, owner-distance numbers, final captures, report.

Owner's rooms, tunnels, passages, landings and strate shells compiled as shapes, solved along
lattice lines with packed signs; rock detail only in a band sized by its supremum; far levels from
the same shapes; multithreaded meshing. 8 workers, BelowNormal, affinity 0xFF00, zero cache hits:
full detail (960 tiles): 669 ms shapes + 290 ms mesh = 0.959 s (was 20.3 s)
full clipmap (6,498 tiles): 870 ms + 1.398 s = 2.268 s (was 170.6 s)
Checks: 5,642 passage centreline samples open; smoothed and per-voxel-noise variants both fail the
detail audit; same hash across runs and 1 vs 6 workers. V toggles owner field / shape world.
Look: 6-12% of lattice signs changed; captures show flat planes without detail (passage floor, a
wall band), telescoping tunnel segments, blocky stair patches. Not accepted as the owner's world yet.

ClipRadius override 3 (64 m at 25 cm). Uncached full detail 20.3 s on 8 workers (512 tiles at
~51 ms serial each should be ~3-4 s: the in-stream inefficiency is unsolved); full clipmap 170.6 s.
The 1 s / 5 s targets were met only from an on-disk mesh cache (.vfmesh, not committed) of
already-generated tiles: a revisit speed-up, not generation speed. Round tunnels gained
deterministic multi-scale wall relief and lost the larger mouth wedges (1.54% of lattice signs
changed, mean 0.20 m). Hashes stable across runs and 1 vs 6 workers.

Cause found by profiling: room/SDF graph-cache churn (exact XY bounds + sample order rebuilt it
constantly). Region grouping (one LOD3 tile: 1,084 -> 229 builds), taller-tile traversal for LOD6
(36,480 -> 12,160), extent-dependent cache slots, lambdas instead of recursive std::function.
Serial ms/tile, 64 nearest tiles per level (before -> after):
L0 50.4 -> 50.6, L1 112 -> 110, L2 24 -> 22, L3 223 -> 73, L4 269 -> 134, L5 393 -> 127, L6 283 -> 145.
Hashes of all levels unchanged; parity 3,436/3,436 bit-identical.
Full clipmap, 16 workers BelowNormal: full detail 66.6 s, all 12,054 tiles 175 s. In-stream L0 tail is
high (median 83 ms, mean 198 ms, p95 669 ms) vs 51 ms serial.
Streaming: recentre keeps the intersection, generates only missing tiles nearest/finest first;
one crossing = exactly 441 new tiles in 6.1 s, no stale results.
Lighting: normals already come from the density gradient; the striping was the squared headlamp;
broad linear fill + warmer palette. Daytime CPU rule documented in Standalone/README.md.

Hashed TMap/TSet and real TInlineAllocator storage did not move level 0 (72.1 -> 74.1 s, within
noise): the slowness is elsewhere. StreamingWorld.h started (first build hit an int64/uint64
mismatch), library plan drafted (SHARED_CPP_LIBRARY_PLAN.md), before-normal captures saved.
Uncompiled/unmeasured parts: streaming. Resume by forking session 01a0fd2e-3c3b-7050-b4e9-628fdcc4d553.

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.
