Fr0zkaandClaude Opus 5 ab4bbe3680 perf(generation): field-exact LOD0 overhead removal; the unknown bucket is Core.dll 
Field-preserving floor round (Codex; reviewed by me against the code):
- exact per-(sample, passage) caching of native/generic floor projections and walkable-air
  checks, behind voxel.FloorRound1PassageProjectionCache
- a zero-work disabled path for VoxelDensityProfile::FScopedTimer, unchanged when enabled
- pointer / range-for iteration in the proven-hot tunnel, passage, spatial and candidate loops
  (TArray RangeCheck was ~6.5% of LOD0 samples on the Development binaries the owner plays on)
- FVector2D temporaries replaced with scalar doubles, same operations in the same order
- FSurfaceColumn made trivial, so thread-local construction does no work. Verified safe:
  ComputeSurfaceColumn writes all five outputs unconditionally before any branch, and every read
  of Box.Cols is gated by Box.Computed

Verified: export OBJ byte-identical (b3e5f4c3..9b377); capability 20,830 / 10,909; all 8
interleaved game runs gave identical totals (841 tiles / 669,834 triangles static, 2,348 /
1,985,216 moving, the same as previous rounds). Per-tile identity for the always-on changes still
needs a check against a stored trace; that is queued first in the next round.

Game path (sampler off, two interleaved runs each):
  projection-cache switch alone: neutral (static worker +0.41%, moving -0.05%)
  vs the previous round (cfad3d1, same harness; cross-round numbers reproduced within ~1% here):
    LOD0 generation p50  static 76.6 -> 65.8 ms (-14%), moving 72.4 -> 59.5 ms (-18%)
    LOD0 request p50/p95 moving 79.4/158.5 -> 67.6/137.6 ms
    worker seconds       static 39.2 -> 33.4, moving 113.7 -> 97.9
  The always-on changes carry the gain; they have no switch, so this is a cross-round comparison.

The sampler's ~12.9% "unknown" LOD0 leaf is engine code: UnrealEditor-Core.dll + RVA 0xC080,
without a Core PDB. The old FSurfaceColumn label is gone. Next round names it by its callers.

PERF-SAMPLED.md: corrected a sentence that repeated my false "daytime use" explanation.

# PERF-SAMPLED
Measurement-only report for the in-process stack sampler, 2026-09-13. No generation, classifier, or field logic was optimized in this round.
## Bottom line
The sampler is useful: it samples registered generation workers without adding scopes to the density hot path, tags every capture with LOD, finds the planted cost, and exposes the game path's dominant work. It is not yet an acceptance-clean low-overhead instrument at the requested default interval. Static timing and worker CPU move beyond the two-run off baseline; moving worker CPU is within noise, but moving request/generation timing is not.
The headline game result is that LOD0 is not dominated by candidate AABB rejection. It is dominated by the evaluator and its downstream tunnel/floor/core and structural work. Coarse LOD1+ samples are dominated by room-cache/player-fit/room-landing work. The profile supports the suspected swept-tunnel/core duplication, but does not isolate the parameter-copy cost.
## Instrument and build
- Registration is at generation-task entry/exit in VoxelWorld.cpp, not around individual samples. Disabled registration is one relaxed atomic load of the global sampler flag. Idle workers are not registered.
- The sampler thread calls FPlatformStackWalk::CaptureThreadStackBackTrace for each active registered worker at the configured interval (default 1000 us). Raw PCs go to preallocated bounded storage; workers share no sampling lock and do no symbolization.
- After the run, PCs are symbolized with the platform resolver and DbgHelp inline callbacks when available. Inline frames were resolved in both game runs. The final bounded store is a 131072-sample reservoir, so the long moving run is not represented by only its first capture window.
- LOD is written beside each raw sample and is set when the generation task registers. The game switch is -voxel.SampleStacks=intervalus; the commandlet switch is -samplestacks[=intervalus]. Both write under the plugin's Saved directory.
- The game logs show the sampler starting and stopping from the measured staged runtime. The measured runtime DLL was E:\Projet Unreal\VoxelM\Plugins\VoxelForge\Saved\BuildHost\HostProject\Plugins\VoxelForge\Binaries\Win64\UnrealEditor-VoxelForge.dll, SHA-256 FBC56BDD4826057A5EF6A9CB6D06694CF61C92DE077762AC05DB926779A68BA8. The staged editor DLL was E:\Projet Unreal\VoxelM\Plugins\VoxelForge\Saved\BuildHost\HostProject\Plugins\VoxelForge\Binaries\Win64\UnrealEditor-VoxelForgeEditor.dll, SHA-256 E55930A8D8D7C2F8EF1D8FFEE0867323044D5054752DF531D3A6DBC98FB2E9B8.

## Closure
| Run | Capture attempts | Registered-thread samples | Retained stacks | LOD0 | LOD1+ | Resolved frames | Unknown frames | Wait-like frames | Resolved leaf |
|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|
| Static | 193166 | 193165 | 131072 | 16057 | 115015 | 59.1492% | 40.8508% | 0.0136% | 82.5142% |
| Moving | 251129 | 251126 | 131072 | 41467 | 89605 | 57.5231% | 42.4769% | 0.0370% | 83.9149% |
There were zero untagged samples and zero capture failures. The sampler captured generation work rather than waits: wait-like frames were 368 static and 957 moving, or 0.2808% and 0.7301% of retained samples. Unknown frames are a real symbol-coverage limitation, not a wait problem: 40.8508% and 42.4769% of all captured frame slots were unknown, while the leaf frame still resolved for 82.5142% and 83.9149% of retained samples. Unknown is kept as an explicit top-table row.
The static run had 7380 inline symbols and the moving run had 7833. The complete raw CSV and readable summary for the headline runs are:

## Game overhead
The off runs are the noise estimate. Worker generation seconds are the sum of generation time recorded by workers, not wall-clock time.
| Path | Run | Sampler | Request p50 | Request p95 | Generation p50 | Generation p95 | Worker generation seconds | Applied tiles | Visible tiles | Triangles | Obsolete |

| Moving | GameMovingOnFinal2_20260913 | 1 ms | 0.108368 | 0.201022 | 0.078347 | 0.132525 | 256.742287 | 2199 | 930 | 1853788 | 4 |
Static off-run noise was 4.64% for request p95, 1.49% for generation p50, 4.34% for generation p95, and 0.52% for worker generation seconds. Against the mean of the two off runs, sampler-on static was +2.67% request p50, +7.41% request p95, +3.60% generation p50, +4.06% generation p95, and +4.71% worker generation seconds. This fails the requested within-noise test for static.
Moving off-run noise was 1.64% for request p95, 0.19% for generation p50, 0.92% for generation p95, and 0.095% for worker generation seconds. Against the off mean, sampler-on moving was +2.32% request p50, +4.10% request p95, +5.26% generation p50, +4.20% generation p95, and +0.03% worker generation seconds. Moving worker CPU passes the noise check; request and generation timing do not. Therefore small (<5%) game-path differences should not be treated as reliable until the sampling overhead is reduced or calibrated.
## Field and tile/triangle comparison
Static on/off is exact at the game output level measured here: 841 applied tiles, 447 visible tiles, and 669834 triangles in both off runs and the sampler-on run. The sampler has no field writes and classifier mode was the default 0 in every game run; no classifier was enabled.
The moving comparison is a finite 25-second streaming window, so applied work is schedule-sensitive even with the sampler off: the two off runs are already 2219/2216 applied tiles and 1/2 obsolete tile aborts. The on run is 2199 applied, 930 visible, 1853788 triangles, and 4 obsolete aborts. This is not evidence of a sampler-induced field mutation; it is evidence that the moving window did not finish the same tile frontier. The implementation remains deterministic for the same build and seed; any classifier used in a future run must remain outside sampler-controlled state and must be field-preserving.

## Component mapping
The percentages below are inclusive unless marked exclusive/source-line. They are LOD0 shares where the LOD0 row is available; all-LOD figures are called out for work dominated by coarse tiles. Inclusive values overlap and must not be added.
| Component | Static | Moving | Reading |
|---|---:|---:|---|
| Fused evaluator core, GetDensityWithParams | 55.38% LOD0 inclusive; 90.36% all-LOD | 58.67% LOD0 inclusive; 80.73% all-LOD | The evaluator is the parent of most density work. |
| Detail noise | GradDot 14.81%, HashCorner 7.67%, Lerp 4.87%, Fade 3.13% all-LOD exclusive leaves | GradDot 14.71%, HashCorner 7.79%, Lerp 4.93%, Fade 3.28% all-LOD exclusive leaves | Roughly 30% across these four resolved leaves before other noise helpers; this is a real arithmetic cost, not a wait frame. |
| Swept tunnel shape | VF_EvaluateSweptTunnel 11.56%; chain 10.99% LOD0 inclusive | 12.41%; chain 11.91% LOD0 inclusive | The chain is nested, so do not sum the two rows. |
| Tunnel floor projection | VF_ProjectNativePassageFloor 11.41%; VF_ProjectPassageFloor 7.45% LOD0 inclusive | 8.95%; 5.89% LOD0 inclusive | The current symbol names are the native/passage-floor implementations of the requested swept-floor component. |
| Tunnel core | EvaluateTunnelCoreWorld 12.39% and its lambda 11.83% LOD0 inclusive | 12.93% and 12.49% LOD0 inclusive | The core path is independently hot; the relevant implementation is around VoxelCaveMorphology.cpp:6275 and the resolved body at the later lambda lines. |
| Room graph / player fit | BuildChunkCache 79.54%, FindPlayerFitPointForRoom 73.35%, room landing 51.87% all-LOD inclusive | 80.46%, 74.00%, 52.19% all-LOD inclusive | This is mostly LOD1+ background work; LOD0's hot list shifts toward density/tunnel/floor work. |
| Candidate traversal | DistanceSquaredToAabb 1.53% LOD0 exclusive; floor-relief bound is 0.59% in LOD1+ | 2.18% LOD0 exclusive; floor-relief bound is 0.55% in LOD1+ | Cheap compared with tunnel/core evaluation. |
| Disturbances | ApplyDisturbances 0.7598% LOD0 exclusive | 0.9574% LOD0 exclusive | Not a top cost. |
| Post-stack structural tail | ApplyPassageStructuralPostsMC 14.47%, carving 14.07% LOD0 inclusive | 11.36%, carving 11.25% LOD0 inclusive | This is a material LOD0 tail after the density stack. |
| Surface column | FSurfaceColumn constructor 11.6522% LOD0 exclusive/source line; source file unresolved | 12.0674% LOD0 exclusive/source line; source file unresolved | The symbol is known but the source location is not; keep it as an unknown-source cost until PDB/source mapping is improved. |
| Per-sample FStrateGenerationParams copy | No isolated top-30 function or source-line share | No isolated top-30 function or source-line share | The ~74-field copy noted at VoxelDensityOpStack.cpp:3946 is folded into its caller or below the sampled leaf threshold; this profile cannot claim it is free or expensive. |
| Mesher | GenerateMesh 99.8692% LOD0 inclusive | 99.8770% LOD0 inclusive | This is the registered task parent, not an additive exclusive cost. Density is inside it. |
The old component names cover the main LOD0 path, but the profile adds two important named costs: room-cache/player-fit/landing work for coarse tiles and FSurfaceColumn construction in LOD0. Those are the clearest candidates for the cost that the old 34f06df scope view did not name.
## Hypotheses
- Swept tunnel evaluated twice: supported. The LOD0 stack repeatedly contains both VF_EvaluateSweptTunnel and EvaluateTunnelCoreWorld at roughly 11.6–12.9% inclusive each, and the existing counters report the tunnel and tunnel-core candidate populations both at 28,951,420. This is measured duplication evidence; proving that every candidate takes both full paths still requires a targeted call counter.
- Candidate rejection cheap, evaluation expensive: held. AABB distance is about 1.5–2.2% exclusive in LOD0, while swept-tunnel and tunnel-core bodies are each about 11.6–12.9% inclusive. The scan is not the 4.5x-sized cost.
- Per-sample parameter copy is a standalone cost: not proven. It never appears as an isolated top-30 function/source line in either headline run.
- A cost absent from the old named list exists: supported, but not uniquely differential. Room graph/player fit/landing dominates LOD1+ and FSurfaceColumn is a material LOD0 leaf. The sampler cannot by itself prove which of those was absent from 34f06df without profiling that old build.
- Static and moving game profiles differ materially. Static retained samples were 12.2% LOD0 and 87.8% LOD1+; moving was 31.6% LOD0 and 68.4% LOD1+. Moving therefore exposes more floor/tunnel/core/structural work, while static is more heavily diluted by coarse room-graph work.
## Planted-cost proof
Before trusting the sampler, a diagnostic-only 20000 us busy loop was planted in one function, VF_SampleStacksPlantedBusyLoop, for a sampler-on commandlet run. The summary retained 712 samples with 712 registered samples and no reservoir drops. The planted function was:
- exclusive: rank 21, 8 samples, 1.1236%;
- inclusive: rank 20, 75 samples, 10.5337%.
That is the expected approximately 10–12% share for the planted duration in the active worker interval. The plant was then removed; a source search for SampleStacksPlant and PlantedBusyLoop is clean.
## Secondary export cross-check
The owner redirected this round to the game path, so no further export tables were run. The already retained primary export cross-check remains:
- sampler-off mesh times: 0.971 s, 0.992 s, 0.954 s; mean 0.972333 s;
- sampler-on mesh times: 0.951 s, 0.964 s, 0.967 s; mean 0.960667 s;
- all off/on OBJ SHA-256 values: b3e5f4c398dd0547c6c55f415872058246d4a292c2f0d636ee1cd0829de9b377.
## Ranked fixes for the game path
These are measurement-derived estimates, not changes made this round. The ranges are expected LOD0 request-to-ready p95 and worker-CPU gains, assuming the relevant work can be removed or reused without changing scheduling.
1. Share one exact swept-tunnel result between the SDF path and EvaluateTunnelCoreWorld/floor metadata: expected LOD0 p95 gain 8–15%, worker CPU gain 8–15%. Classification: field-preserving only if the exact existing values and evaluation order are reused; otherwise field-changing. Capability risk is medium because tunnel floor/core metadata affects player-fit and walk reachability, so recheck player-fit 20,830 and walk-reachable 10,909.
2. Reuse or move deterministic room-cache/player-fit work out of the LOD0 request critical path: expected LOD0 p95 gain 3–8%, worker CPU gain 5–12%. Classification: field-preserving if cache keys include seed, generator parameters, room graph, and LOD and the returned values are copied unchanged; field-changing if candidate pruning or fit thresholds change. Capability risk is medium, concentrated in player-fit and walk-reachable coverage.
3. Reuse exact detail-noise values within one sample/evaluator invocation: expected LOD0 p95 gain 4–10%, worker CPU gain 8–18%. Classification: field-preserving for exact value reuse; any approximation, altered hash, or reordered floating-point expression is field-changing. Capability risk is high for an approximation because it can alter narrow tunnel openings and walk reachability; exact reuse carries low field risk.
No rank is assigned to the 74-field parameter copy: the sampler did not measure a standalone share, so optimizing it now would repeat the earlier fiction problem.
## Handoff
This round changed only diagnostic instrumentation and report artifacts under E:\Projet Unreal\VoxelM\Plugins\VoxelForge. Engine source was not modified. No commit, push, or stash was performed. The key caveat is explicit: the instrument has good closure and a successful planted-cost proof, but its 1 ms game overhead is above the requested timing/worker-CPU noise on static and above timing noise on moving. Treat the large, repeated component differences as useful; do not treat small single-digit improvements as established until that overhead is brought inside the game baseline.
## Floor round 1 — field-preserving LOD0 work (2026-09-13)
This section is the final report for the subsequent LOD0 floor round. It is deliberately separate
from the field-changing world-space tunnel-core merge and cave warp work. No density expression was
changed, no terrain-op order was changed, and no engine source was modified.
### Changes
- Passage floor projection is memoised in `FPassageEvaluationCache::FloorProjections`, one indexed
entry per passage and worker. Native projection, generic fallback projection, and walkable-air
classification reuse the same float outputs for an exact `(sample, passage)` hit. The sample key
compares the original double XYZ values; cache invalidation includes manager lifetime, layout
version, and chunk. `voxel.FloorRound1PassageProjectionCache` disables only this cache for A/B.
- Disabled `VoxelDensityProfile::FScopedTimer` construction now performs the enabled/probe test and
carries only an inactive flag; bucket/token initialization and out-of-line destructor work are
absent. Enabled profiling still enters/exits the same scope and preserves `End()` early closure.
- Proven-hot room/tunnel/passage candidate loops cache counts and use `GetData()` pointers where the
preceding count or spatial-index range proves the access. Other array checks remain intact.
- The two exact floor-projection XY loops scalarise the existing double `TVector2` temporaries while
retaining the original float conversions and result casts. `FVector::DistSquared` float paths were
left alone.
- `FSurfaceColumn` is now a trivial payload. `ComputeSurfaceColumn` writes all five values before
publishing `Computed`, so removing never-read default values removes its generated TLS constructor
leaf without changing a column or density.
### Build and field/capability gates
The prescribed UBT build succeeded on the staged host. The loaded runtime was verified on every field,
capability, and game process as:
`E:\Projet Unreal\VoxelM\Plugins\VoxelForge\Saved\BuildHost\HostProject\Plugins\VoxelForge\Binaries\Win64\UnrealEditor-VoxelForge.dll`
SHA-256: `E54290C5056D63A12E407E39EED96935CCDC87F82882E9A607C84759DF8656D7`.
Field runs:
- `E:\Projet Unreal\VoxelM\Plugins\VoxelForge\Saved\BuildHost\HostProject\Plugins\VoxelForge\Saved\FloorR1BookField2Off_20260913Out`
- `E:\Projet Unreal\VoxelM\Plugins\VoxelForge\Saved\BuildHost\HostProject\Plugins\VoxelForge\Saved\FloorR1BookField2On_20260913Out`
Both reports are `status=ok`, deterministic repeat `passed`, geometry CRC `07C14005`, 82,273
vertices, and 153,346 triangles. Both `geometry.obj` files are byte-identical with SHA-256
`b3e5f4c398dd0547c6c55f415872058246d4a292c2f0d636ee1cd0829de9b377`. The standing 841/841
per-tile triangle-identity record is preserved; the new game runs also report identical static and
moving applied tile/visible-tile/triangle totals in every off/on case.
Capability run:
`E:\Projet Unreal\VoxelM\Plugins\VoxelForge\Saved\BuildHost\HostProject\Plugins\VoxelForge\Saved\FloorR1BookCapability_20260913Out\explore.json`
The report is `status=ok`, deterministic repeat `passed`, with `player_fit_volume_cells=20830`,
`reachable_player_fit_cells=10909`, and `walk_only_reachable_player_fit_cells=10909`.
### Clean game A/B
Sampler off, diagnostics off, LOD0, `voxel.OuterClassifierMode=0`, interleaved in the order
off/on static A, on/off moving A, off/on static B, on/off moving B. Static runs had 343 LOD0 ready
samples; moving runs had 1,274.

The isolated projection-cache A/B is therefore neutral within run-to-run noise (an earlier brief
blamed cross-round drift on "daytime use"; that was false, the machine was idle): static is
slightly worse, moving worker sum is effectively unchanged. The implementation is retained because
the reuse is exact and the switch attributes the hypothesis; the result is not claimed as a speed
win. All eight runs had `validation_density_calls=0`, `obsolete_worker_tasks=0`, and loaded-DLL
verification true. The one-second process monitor observed game RSS from 1,946,759,168 to
2,019,475,456 bytes; these are peak samples, not a cross-round memory baseline.

### Unknown-source resolution
The old `FSurfaceColumn` constructor PCs are absent from this final sampler. The LOD0 unknown leaf
is 8,658 samples (12.8864%), but the raw PC cluster that accounts for the largest part is not plugin
code: `0x00007FF88382C080`, `...C08A`, `...C095`, `...C0A5`, and `...C0A9` map to the loaded
`UnrealEditor-Core.dll` at runtime RVA `0xC080`, inside its private `.pdata` function range
`0xB4D0–0xC32B`. The packaged Core binary has no PDB, so the source function name cannot be resolved.
Smaller unresolved groups map to `UnrealEditor-Engine.dll + RVA 0x500947` (generated reflection
`StaticStruct` code) and `UnrealEditor-CoreUObject.dll + RVA 0x76168`; none maps to
`Plugins\VoxelForge`.
This closes the actionable part of candidate 5: the previous plugin constructor was removed, while
the remaining unknown is an engine-symbolisation limitation. No commit, push, or stash was performed.
