Five conflicts resolved (CURRENT-STATE, ResolvedLayoutInternal.h, StreamBenchmarkHeadless.cpp, StreamBenchmarkPipeline.h, WorldAssemblyPrototype.h) keeping liminal + cave planner; L156 band fit only; evaluator v239 with v239 baselines (18/18 Clang/GCC W1/W8/W12). Fast tier FAILS (FI upper arrival: 40 unsupported chamber samples, 10 chamber-floor shell violations); TN and VS composed sweeps 0/16 (passage, seam, shell gates). Living plane loads at PostConfigInit (UE smoke passes). Source/: VoxelForgeCoreAdapter.cpp; VoxelForge.uplugin.

## Measurement
|
||
|
||
Two `assembler/world` binaries had identical SHA-256. On Surface World, their L80 near-ready medians differed by +0.52% at W8 and −0.59% at W12. The no-op v228 control differed by −0.37% and −0.05%; its stream hashes matched v227. Use ±1% as the median noise floor. Individual paired controls varied by up to about 2.5% (3.6% for one no-op pair).
|
||
|
||
The three-run L77 profile sampled LOD 0–8 with no lost samples. Function share changes, `HEAD` versus `assembler/world`: `CachedColumn` +0.93 pp, shared column `TryRead` +0.58 pp, `prepareSweptTubeBase` +0.38 pp, and `sweptSample` +0.17 pp. `ApplyResolvedStratePassageCarves` fell by 0.97 pp and `FindBoundStratumForManagerZ` by 0.39 pp. The profile points more toward column-cache work and the sweep lookup than mouth-profile work; it does not isolate one cause for every world.
|
||
|
||
Changes retained: removed the unused `floorShellSignedDistance` sample field; removed per-lookup shared-pointer refcounting and batched diagnostic counters per query scope.
|
||
|
||
## L80 near-ready medians
|
||
|
||
Each delta is candidate versus `assembler/world`; the A/A median noise floor is ±1%.
|
||
|
||
| World | W8 delta | W12 delta |
|
||
|---|---:|---:|
|
||
| Surface World | +3.58% (±1%) | +2.90% (±1%) |
|
||
| Floating Islands | +0.19% (±1%) | +2.20% (±1%) |
|
||
| Tunnel Network | −3.60% (±1%) | +6.84% (±1%) |
|
||
| Vertical Shafts | +4.31% (±1%) | +3.96% (±1%) |
|
||
|
||
The requested targets are not met except Floating Islands W8 and Tunnel Network W8. Whole-view medians were within −8.39% to +0.27% of baseline.
|
||
|
||
## Verification
|
||
|
||
Fast tier passed (273 checks); the composed sweep passed 16/16 seeds with seams and blocked controls; Clang/GCC W1/W8/W12 matched all 13 hashes. Linux UE host build passed with `-NoUBA -MaxParallelActions=4` and no `prlimit`. Output audits stayed green, so version and baselines were left unchanged. No commit, push, or stash.
