Verified before the reset (density + full mesh hashes equal at 1/8/16 workers, routes 5642/5642,
look audits green):
- merged field lookups, parallel mask merge, compact inline spatial bins, line-local relief hash
cache, lattice-specific mesher entry, fused sign+magnitude evaluation, far connectors as one
capsule each (181,836 -> 16,491 far primitives).
- 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
ceiling/ground material grouping (best cold whole view 0.958 s @16 workers) and a far-bin reserve
tweak. Those skips drop data the plugin's materials may need: not a game-path win as-is.

- Removed the thin automatic room-support slabs that left floating caps (in-view detached thin
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.
