Fr0zkaandClaude Opus 5 26b34765d5 perf(generation): exact worm block skip with a proven 3D Perlin bound -- measured NEUTRAL
The sampler put the worm carve's first noise call (VoxelGenerator.cpp:3985, FusedWorm) at 19.4% of
LOD0. The worm only carves where N1 + N2 < T with N2 >= 0, so where N1 >= T it contributes nothing,
bit for bit. A block proven to have N1 >= T everywhere can skip both noise calls exactly.

- The Lipschitz bound for this Perlin3D implementation: L = (15/4) * sqrt(3) * 1.25 = 8.118988160,
  in scaled-N1 units, with a 1e-3 float-rounding margin. Adversarial sampling found a worst ratio
  of 3.187 (0.39 L). The existing 2D floor-relief bound (8.5) is a component bound of a different
  field and was confirmed not to transfer.
- A soundness test that can fail (VoxelForgeWormBlockSkipTest): 6,476 proved blocks, 355,945 exact
  lattice samples, 0 violations. A deliberately halved L proves a bad block; the full L rejects it.
- voxel.WormBlockSkip, default 1.

Field exact: export OBJ byte-identical (b3e5f4c3..9b377), 841/841 keyed tiles identical to
NextHeadStaticTrace_20260913, capability 20,830 / 10,909.

RESULT, stated plainly: no measurable speed gain. The skip rate is 4.07% of worm-eligible LOD0
samples and 0% at LOD1-4, because the bound is ~2.5x looser than the worst observed ratio at the
block size used. Paired on-vs-off, two interleaved runs each: static worker +2.15%, generation p50
+1.8%; moving worker -1.42%, request p50 -2.5%. Within noise. The next round turns the default OFF.
The proven bound and its test are kept for a tighter skip later (smaller or hierarchical blocks,
or a per-cell bound).

Run ledger (from Codex's report): the first build failed on an ambiguous test overload and was
fixed; two timing runs are void because the orchestrator stopped the session so the owner could
use the PC; the eight valid timing runs, the sampler run and the diagnostics runs completed. No
new crash folders. PERF-SAMPLED.md now lists all eight earlier-round UECC crash records.

Raw Blame History

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.

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.

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.

  • 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.

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.

Worm block skip round (2026-09-14)

Proof and gates

The worm skip is enabled by default through voxel.WormBlockSkip=1. It is fail-closed and only removes the two worm noise calls after the unchanged WormNetworkRange mask has passed. The worker-local cache is keyed by generator owner, seed, params/layout fingerprint, tile origin, step, lattice size, and worm parameters; it is never shared across tiles or workers.

For this implementation's actual GradDot set, the unique gradients are (±1,±1,0), (±1,0,±1), and (0,±1,±1). The exact finite-support partial-derivative relaxation with Fade'(t)=30t²(1-t)² has supremum 15/4, attained at (0.5,0.5,0.5). Therefore the noise-space vector bound is

L = (15/4) * sqrt(3) * VOXEL_NOISE_SCALE = 8.118988160 (VOXEL_NOISE_SCALE=1.25).

The existing 2D floor constant was proven differently and does not transfer: its comment uses the loose component bound [-1,1], four-edge interpolation difference bound, and max SmoothCurve' = 1.875, giving 1 + 4*1.875 = 8.5 per partial. The worm derives its bound from the actual 3D gradient support. The block radius is measured after the exact X/Y/Z noise transform, including WormFrequency, VerticalScale, and WormHorizontalBias; Abs is 1-Lipschitz and the positive noise scale is included in L. A 1e-3 scaled-output margin is subtracted before the threshold comparison. It is deliberately much larger than the accumulated float rounding at the center/radius operations and is covered by the soundness test.

The adversarial attack used dense corner/face sampling plus random pairs: 17,365,280 pairs, worst scaled ratio 3.187330411, or 0.392577295*L. The fail-capable automation test also audited 6,476 proved blocks over 355,945 exact lattice samples with zero violations. A deliberately halved L proves the negative-control block while the exact point has N1=0.011259466 < 0.015 and the full L rejects it.

Default-on export is byte-identical to the baseline: geometry hash B3E5F4C398DD0547C6C55F415872058246D4A292C2F0D636EE1CD0829DE9B377, 82,273 vertices, 153,346 triangles. The static trace is 841/841 keyed tiles with zero field/empty/triangle differences. Capability remains 20,830 / 10,909.

Clean game A/B

Sampler off, diagnostics off, voxel.OuterClassifierMode=0, interleaved static and moving runs. Static runs had 343 LOD0 ready samples; moving runs had 1,274. All valid runs had identical applied geometry totals, zero validation calls, zero obsolete worker tasks, and verified the loaded plugin module. The clean timings below used the staged runtime before the final counter-only diagnostic-accounting rebuild (81F52389A78543E41EEC8E3E40DEF8F2634A79EB83E2A933FF35EE42CD611E12). That patch is behind diagnostics, so it does not change this clean path. The final staged runtime used by the last diagnostic run is E72E140100B3D258F28E9DBA19CD95D379D98794DA49D24C708FDD01B5B5FE08.

The two-run result is mixed: moving improves modestly, while static is within ordinary run noise and is slightly worse on worker sum. The switch remains default-on because the field proof is exact; the timing result is not presented as a universal speed claim.

Skip rate

The final diagnostics-enabled moving run used the final DLL and emitted 2,360 tile profiles. The rate is worm_block_skipped / worm_eligible, not a fraction of all density samples:

Sampler-on moving profile

WormSkipGameOnMovingSampler_20260914 retained 96,649 samples with zero drops and zero capture failures: 61,869 LOD0 and 34,780 LOD1+. It ran for 24.972305 s; resolved-frame fraction was 52.9174%, unknown-frame fraction 47.0826%, wait-like fraction 0.1011%, and resolved-leaf fraction 95.3388%.
