# Shape world speed round — final half-load verification

## Round 5 — far-field LOD8 trial (2026-10-04)

### Result and decision

The coarse far-shell candidate meets the requested **under-1.5 s** W8 process-wall threshold on two cold, full-payload runs, but I did not promote it: a remote yaw-90 capture changes 28,982 of 1,024,000 pixels versus LOD6 (max channel delta 38), and no per-shell/per-connector coarse-sampling survival proof exists. The source and rebuilt default therefore remain at exported LOD6. The LOD8 experiment is reproducible with `--max-clip-level=8`; it is not evidence that thin strata, seals, or distant connectors all survive.

### Cold full-payload W8 measurements

All runs used `--force-generate`, 8 workers, full UVs/colors/material groups, no cache, BelowNormal priority and affinity `0xFF00`. Process wall includes startup and world setup; collision cooking and GPU upload are outside this standalone measurement.

| Max LOD | Process wall A/B (mean) | Shape stage A/B (mean) | Full-detail stream A/B | Full clipmap A/B (mean) | Tiles | Payload allocation | Cache hits |
| --- | ---: | ---: | ---: | ---: | ---: | ---: | ---: |
| 6, final exported default | 1.809 / 1.664 s (**1.737 s**) | 706 / 696 ms (**701 ms**) | 247 / 226 ms | 850 / 861 ms (**856 ms**) | 6,498 | 235.29 MiB | 0 |
| 8, candidate | 1.406 / 1.289 s (**1.348 s**) | 698 / 703 ms (**700 ms**) | 215 / 212 ms | 434 / 431 ms (**433 ms**) | 2,226 | 92.61 MiB | 0 |

The candidate cuts full clipmap wall by about 49% and reduces LOD6–8 samples from 32.717 M to 3.415 M (about 90%). It retains full payload channels. The full-payload logs are [default LOD6 A](round5_final_default6_full_payload_w8_a.stdout.log), [B](round5_final_default6_full_payload_w8_b.stdout.log), [candidate LOD8 A](round5_final_default_full_payload_w8_a.stdout.log), and [B](round5_final_default_full_payload_w8_b.stdout.log), with runner records alongside them. LOD6 remains 0.237 s above the process-wall target on this pair; the candidate is 0.152 s below it.

### Determinism and audits

The final LOD6 executable, [build log](round5_farfield/round5_default6_build.log), matches all 36 density/mesh/full-payload/oriented-topology fields across W1/W8 for full detail, whole clipmap, and LOD0–6: [comparison](round5_final_default6_hash_compare.log), [W1](round5_final_default6_hash_w1.stdout.log), [W8](round5_final_default6_hash_w8.stdout.log). The candidate LOD8 W1/W8 comparison matches all 44 fields across full detail, whole clipmap, and LOD0–8: [comparison](round5_lod8_default_hash_compare.log), [W1](round5_lod8_default_hash_w1.stdout.log), [W8](round5_lod8_default_hash_w8.stdout.log). Both workloads report 5,642/5,642 route samples open and zero cache hits. The W8 shard audit passes for LOD0 (zero isolated-in-view small components); it does not cover coarse far-shell survival.

The final default's W8 shape/look audit is green: route, room-floor, floor-slope, floor-profile, tunnel-radius, flat-surface, grid-stair, thin-sheet, strata/cave surface-band, flat-patch, detail, and spatial-scale checks all pass. See [audit output](round5_final_default6_shape_audit_w8.stdout.log). The LOD8 candidate audit is [here](round5_lod8_shape_audit_w8.stdout.log); these audits run the detailed shape checks in the near compiled region and are not the missing far-LOD survival check.

### Captures and far-field discrepancy

The six requested before/after capture pairs were taken after `[InitialClipmapReady]`. The LOD6 and candidate LOD8 images compare pixel-identically for chamber, tunnel, passage, far yaw 0, floor close-up, and tunnel bend; the three additional center-camera far directions (yaw 90/180/270) also compare exactly. [Pixel comparison](round5_default_capture_pixel_compare.stdout.log). Example: [LOD6 chamber](round5_farfield/lod6_fixed_chamber.png) / [LOD8 chamber](round5_farfield/default_fixed_chamber.png); [LOD6 far yaw 90](round5_farfield/lod6_far_yaw90.png) / [LOD8 far yaw 90](round5_farfield/default_far_yaw90.png).

I added a remote camera at X=500 m and swept four headings. At yaw 90, the candidate changes 28,982 pixels (86,923 channels; mean absolute channel delta 0.227); the changed region is concentrated in lower far silhouettes. Yaw 180 is identical; yaw 270 changes 143 pixels with max delta 1. Yaw 0's 19 pixels at max delta 1 match same-LOD capture jitter: a repeated LOD6 image differs by the same 19 pixels, and that repeat is identical to LOD8. The LOD7 yaw-90 image is pixel-identical to LOD8, so LOD7 does not resolve this case. See [remote sweep comparison](round5_remote_sweep_pixel_compare.stdout.log), [capture variance check](round5_remote_capture_variance_compare.stdout.log), [LOD6 yaw 90](round5_farfield/lod6_remote_x500_yaw90.png), [LOD8 yaw 90](round5_farfield/default_remote_x500_yaw90.png), [LOD7 yaw 90](round5_farfield/lod7_remote_x500_yaw90.png), and [scaled difference](round5_farfield/remote_yaw90_diff_x5.png). The mismatch is small in area but real; without a feature-survival proof I am keeping the safe default at LOD6.

### Builds and failed invocations

Both the temporary-default-LOD8 candidate and the restored-default-LOD6 executable built successfully with `/MP8` or less under the machine cap. The build logs contain the recurring French `vswhere.exe` diagnostic and six existing C4838 warnings; both builds exited successfully. Two initial W1/W8 hash-launch wrappers failed before starting a child because of malformed PowerShell array syntax; corrected launches both exited 0. An initial comparison parser also counted only one hash per output line (9 fields); the corrected all-match parser compared 36/36 and passed. No workload or build failed with `0xC0000142` or showed an out-of-memory condition. No viewer was closed.

No source diff remains: the exported LOD6 default was restored and rebuilt as [VoxelForgeRound5Default6.exe](../../../bin/VoxelForgeRound5Default6.exe); the LOD8 candidate remains available as [VoxelForgeRound5Farfield.exe](../../../bin/VoxelForgeRound5Farfield.exe). No commit, push, or stash was made. The far-field goal is not complete: next work needs an explicit shell/connector survival checker and likely feature-aware refinement or explicit far surfaces before the faster sampling can become the default.

## Round 3 update — measured payload path and current result

This update supersedes the earlier headline timings, hash values, and capture references below. The sections that follow retain the previous-round context. With the exported LOD6 limit, the latest cold full-payload W8 pair averaged **1.917 s**. The best tested opt-in LOD8 far-shell pair averaged **1.451 s**, still **0.451 s above** the under-one-second goal. The LOD8 option is `--max-clip-level=8`; it retains LOD0–5 and distributes the same render distance over LOD6–8. Cache hits were zero in every run.

| Exported LOD6 cold W8 run | Process wall | Shape stage | Full-detail stream | Full clipmap stream | LOD6 complete | Cache hits |
| --- | ---: | ---: | ---: | ---: | ---: | ---: |
| A | 1.915 s | 0.874 s | 0.216 s | 0.870 s | 0.869 s | 0 |
| B | 1.919 s | 0.839 s | 0.217 s | 0.881 s | 0.867 s | 0 |
| Mean | **1.917 s** | **0.856 s** | **0.217 s** | **0.876 s** | **0.868 s** | **0** |

Both runs generated the same full workload: 6,498 clipmap tiles, including 4,770 LOD6 tiles; 32.717 M LOD6 density samples; 1,834,816 LOD6 vertices; 235.49 MiB full-payload allocation. The process wall includes startup and world setup. Collision cooking and GPU upload are outside this standalone measurement. The earlier 1.823 s pair on the same source is in [A](round3_finalclean_full_w8_a.stdout.log) and [B](round3_finalclean_full_w8_b.stdout.log); the latest repeat logs are [A](round3_post_classifier_full_w8_a.stdout.log) and [B](round3_post_classifier_full_w8_b.stdout.log). The change still reduces the original 2.155 s process-wall mean, but the target remains unmet by about 0.9 s on the latest pair.

### Opt-in LOD8 far-shell candidate

| Cold W8 run with `--max-clip-level=8` | Process wall | Shape stage | Full-detail stream | Full clipmap stream | LOD8 complete | Cache hits |
| --- | ---: | ---: | ---: | ---: | ---: | ---: |
| A | 1.442 s | 0.853 s | 0.250 s | 0.429 s | 0.426 s | 0 |
| B | 1.459 s | 0.854 s | 0.223 s | 0.426 s | 0.423 s | 0 |
| Mean | **1.451 s** | **0.854 s** | **0.237 s** | **0.428 s** | **0.425 s** | **0** |

This candidate generated 2,226 tiles instead of 6,498: 96 each at LOD6 and LOD7, plus 306 at LOD8. LOD6–8 together used 3.415 M density samples versus 32.717 M for the exported LOD6 shell. Full-payload allocation fell from 235.49 MiB to 92.81 MiB. Full UVs, colors, biome channels, and ceiling/ground groups remained enabled. Against the latest exported-LOD6 pair, process wall improved by 0.466 s and clipmap stream wall by 0.449 s. The process still misses the one-second target.

### Payload profile and retained change

Controlled skip runs isolate the payload costs. On the pre-optimization full-payload profile, skipping colors lowered clipmap stream time from 1.119 s to 0.754 s (about **365 ms** and 2.93 worker-seconds saved). This is the dominant measured payload cost: the mesher calls `GetBiomeMaterialAt` for each vertex, and that call resolves the biome field. Skipping UVs alone measured 1.132 s versus 1.119 s for full payload, so UV emission showed no measurable wall-time cost. Skipping material groups measured 0.943 s against a 1.117 s full run (about 174 ms); the path performs per-column ceiling/ground classification and retains the actual two sections in the default output. These are diagnostic ablations only; the final path keeps all channels and groups. The measurements are in [full payload](round3_payload_split_full_w8.stdout.log), [UV skip](round3_payload_skip_uv_w8.stdout.log), [color skip](round3_payload_skip_colors_w8.stdout.log), and [group skip](round3_payload_skip_groups_w8.stdout.log).

The retained change is in the standalone [mesher](../../../Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp). It changes only far LOD biome colors at `Step >= 64`. For each far tile and vertical chunk it evaluates the biome field at the four tile corners. Each vertex takes the nearest corner’s dominant/neighbour palette pair; the border-blend value is bilinearly interpolated when all four corners share that pair. Adjacent tiles use the same shared corner coordinates. The slope channel remains derived from the exact vertex normal, UVs remain exact, and ground/ceiling classification and section ordering are unchanged. This keeps the same payload meaning while reducing repeated far-field biome evaluations. Full clipmap stream time fell from the previous 1.113 s mean to 0.857 s in the earlier clean pair and 0.876 s in the latest repeat; LOD6 completed in 0.853 s and 0.868 s respectively.

The payload hash changes at LOD6 and whole-clipmap level because those far color values are coarsened. Density, geometry, and oriented-topology hashes remain unchanged. A smaller 2×Step grid that did per-vertex map finds added about 68 ms and was rejected.

### Exported LOD6 1-worker / 8-worker hash matrix

The rebuilt full-payload executable produced identical hashes at 1 and 8 workers for every output below. Both runs had zero cache hits and all 5,642/5,642 route samples open. The latest exact-binary comparison is [W1](round3_post_classifier_hash_w1.stdout.log) versus [W8](round3_post_classifier_hash_w8.stdout.log); nine aggregate outputs had zero hash-field mismatches.

| Output | Density hash | Geometry hash | Full payload hash | Oriented topology hash |
| --- | --- | --- | --- | --- |
| Full detail | 0xa071e48a996e2828 | 0x6f270c621d39302f | 0x33c7353b2eda16a7 | 0x1b39c8cc2ffed4b3 |

The exported-LOD6 captures use the same six fixed cameras as the previous set. Every view is pixel-identical to its reference (1,024,000 pixels, zero changed pixels/channels, maximum channel delta 0): [chamber before](final_halflimit_after_chamber.png) / [after](round3_after_chamber.png), [tunnel before](final_halflimit_after_tunnel.png) / [after](round3_after_tunnel.png), [passage before](final_halflimit_after_passage.png) / [after](round3_after_passage.png), [far before](final_halflimit_after_far.png) / [after](round3_after_far.png), [floor close-up before](final_halflimit_after_passage_floor_closeup.png) / [after](round3_after_passage_floor_closeup.png), and [tunnel bend before](final_halflimit_after_tunnel_bend.png) / [after](round3_after_tunnel_bend.png). Shape audits remain green: grid-stair metrics are 0.003 / 0.028 / 0.205 against the 0.400 threshold; detail, join, and tunnel-radius audits pass; the whole-view shard audit reports zero thin sheets and zero isolated small components (four boundary-touching components). Logs: [chamber](round3_shape_audit_chamber_w8.stdout.log), [tunnel](round3_shape_audit_tunnel_w8.stdout.log), [passage](round3_shape_audit_passage_w8.stdout.log), and [whole-view shard audit](round3_shard_audit_w8.stdout.log).

### LOD6 proof experiments and remaining opportunity

- A conservative whole-tile uniformity proof classified zero of 4,770 LOD6 tiles as uniform and raised stream wall time to 1.169–1.195 s. Rejected; logs: [A](round3_far_payload_w8_a.stdout.log), [B](round3_far_payload_w8_b.stdout.log).
- An 8-cell sub-block proof omitted 21% of LOD6 density samples (32.717 M to 25.830 M), but its classification overhead canceled the savings: no-hash stream time was effectively unchanged. It preserved geometry and payload hashes across workers, but changed the diagnostic density digest because omitted samples use sentinels. The sparse path was removed; the final density hashes above are from the full sampling path. Logs: [build](round3_sparse_lod6_build.log), [timing A](round3_sparse_lod6_w8_a.stdout.log), [timing B](round3_sparse_lod6_w8_b.stdout.log), [hash W1](round3_sparse_lod6_hash_w1.stdout.log), and [hash W8](round3_sparse_lod6_hash_w8.stdout.log).
- A later fast-classifier plus sparse-mask prototype used coarse 1,024-voxel occupancy bins and 8-cell proof blocks. Per-tile diagnostics reported 3,267–3,971 samples versus 6,859 in the full grid, but the aggregate LOD6 counter still reported 32.717 M; the two counters disagreed, so the run did not establish a whole-view sample reduction. Three no-hash stream times were 0.872 s, 0.929 s, and 0.892 s, with no repeatable gain over the retained build. It was removed without a hash or capture acceptance. Logs: [first build failure](round3_classifier_fast_sparse_build.log), [corrected build](round3_classifier_fast_sparse_build_retry.log), [timing](round3_fastclassifier_sparse_w8_a.stdout.log), [diagnostic run](round3_classifier_debug_w8.stdout.log), and [sample-count diagnostic](round3_classifier_count_debug_w8.stdout.log).
- A uniform-block proof at Step=256 on the opt-in LOD8 shell left its 2.099 M density-sample count unchanged and measured 0.429 s stream wall versus 0.426–0.429 s without proof. It was removed. Logs: [build](round3_maxlevel8_blockproof_build.log), [run](round3_maxlevel8_blockproof_w8_a.stdout.log).
- A per-vertex color-cache refinement removed map-entry copies and palette-pair checks, but its two W8 clipmap samples (0.866 s and 0.860 s) were within timing variation. It was reverted; logs: [A](round3_farcolor_cache_w8_a.stdout.log) and [B](round3_farcolor_cache_w8_b.stdout.log).
- Existing LOD6 tiles had no complete 2x2x2 or 4x4x4 groups, so direct coalescing was rejected; see [diagnostic run](round3_supertile_diag_w8.stdout.log) and [build](round3_supertile_diagnostic_build.log). A separate `--max-clip-level=8` override asks the desired-set builder for actual LOD7/8 shells and is measured below. One earlier run used unsupported `--stream-max-lod=8`; it exited successfully but silently retained the LOD6 filter.
- Explicit surfaces emitted from known far shapes remain open. The opt-in LOD8 candidate reduces the far sampling cost, but the fixed captures do not prove that every remote thin stratum survives. Its LOD8 shell completes in about 0.425 s; the serial shape stage now dominates at about 0.854 s. Reaching under one second requires another roughly 0.45 s reduction or overlap in that shape stage.

The opt-in LOD8 candidate is in [StandaloneViewer.cpp](../../../Source/StandaloneViewer.cpp). After the final clean build, its W1/W8 hash runs matched all 11 aggregate outputs with zero mismatches; the full-clipmap hashes are density `0x2809003356cf8162`, geometry `0x0123c52b74ad7e7c`, payload `0xcdef10ebb6b24321`, topology `0x1fa3bf7db18a2c8d`. Cache hits were zero and the route audit stayed at 5,642/5,642. Logs: [W1](round3_maxlevel8_final_clean_hash_w1.stdout.log), [W8](round3_maxlevel8_final_clean_hash_w8.stdout.log).

## Round 4 — surface detail band

### Profile and cost

The original W8 profile used the unchanged coherent field and sampled one in 256 distance calls and one in 64 detail calls. It completed the shape audit at BelowNormal priority and affinity `0xFF00`; routes were 5,642/5,642. Logs: [profile output](round4_profile_w8.stdout.log), [runner](round4_profile_w8.runner.log).

| Surface-band profile | Original W8 path |
| --- | ---: |
| Candidate visits / `EffectiveRockDistance` evaluations | 12.021 M / 12.021 M |
| `DetailNoiseOnLine` evaluations / retained proxies | 7.072 M / 7.072 M |
| Detail evaluations per candidate | 0.588 |
| Sign flips | 570,546 |
| Band wall / worker sum | 609.4 ms / 4.848 s |
| Worker time per candidate | 403 ns |
| Sampled distance evaluation | 134.7 ns; 1.619 worker-s estimated |
| Sampled detail evaluation | 478.2 ns; 3.382 worker-s estimated |
| Per-worker candidates / active time | 1.479–1.516 M / 605.9–606.1 ms |

The sampled work estimates total about 5.00 worker-s, slightly above the measured 4.85 worker-s. They are attribution estimates, not an additive timing decomposition. `DetailNoiseOnLine` is the largest measured cost at about 70% of worker time. It evaluates the three line-cached relief octaves and, on applicable strata, owner cave roughness (FBM/ridged/cellular noise and possible domain warps). The workers finish evenly; candidate-count spread is 2.5%, so thread balance is not the bottleneck.

### Retained candidate and measured result

The retained standalone candidate combines a conservative local amplitude envelope with an 8-voxel Z lattice for owner cave roughness. `DetailBand` stays at 6, because a radius-5 candidate mask fails the grid-stair audit. At each candidate, the local fade uses the macro relief, surface depth, cave/floor influence, and layer roughness bound; the plateau is 1.5 voxels and the edge is clamped to the coherent field’s supremum plus its 0.125-voxel margin. Owner roughness cores are evaluated at globally aligned 8-voxel Z anchors and linearly interpolated. The same deterministic owner path is used at all worker counts. This changes the relief field; the captures and hashes below are for the changed field.

The final W8 sampled profile reports 9.389 M candidates, 9.389 M distance evaluations, 3.527 M detail-noise evaluations, 6.755 M proxies, and 550,169 sign flips. Detail evaluations fell 50.1% from the original profile; 3.228 M candidates skip local detail, or 34.4% of candidate visits. Detail evaluations per candidate fell from 0.588 to 0.376. Per-worker candidates were 1.136–1.210 M and detail evaluations 426–455 K; active times were 510.54–510.74 ms. The output is [round4_owner_coarse8_profile_w8.stdout.log](round4_owner_coarse8_profile_w8.stdout.log), with [runner record](round4_owner_coarse8_profile_w8.runner.log).

The profile also reports a sampled 875 ns detail call, with nested relief/layer/owner scopes. Those added clocks run inside the sampled call and materially perturb it; the 875 ns value and its nested estimates are not production costs and should not be compared directly with the original 478 ns. The uninstrumented interleaved shape-audit timings give a better speed comparison:

| Owner roughness lattice | W8 surface-band samples | Median |
| --- | ---: | ---: |
| 4 voxels | 613.166 ms, 559.883 ms | 586.525 ms |
| 8 voxels | 522.047 ms, 588.253 ms | 555.150 ms |

The step-8 median is 5.3% below step 4, but spread remains substantial. The separate first step-8 audit was 538.295 ms. The paired logs are [step 4 A](round4_coarse_ab_step4_a_w8.stdout.log), [step 8 A](round4_coarse_ab_step8_a_w8.stdout.log), [step 8 B](round4_coarse_ab_step8_b_w8.stdout.log), and [step 4 B](round4_coarse_ab_step4_b_w8.stdout.log). The speed target is not met: the best repeated band measurements remain around 0.50–0.59 s, well above 200 ms.

### Full-payload headline

Two cold no-hash W8 runs used full UVs, colors, and material groups, generated all 6,498 clipmap tiles, and recorded zero cache hits. Process wall includes executable startup and world setup; collision cooking and GPU upload are not included.

| Cold full-payload run | Process wall | Shape stage | Surface band | Full-detail stream | Full clipmap stream | Cache hits |
| --- | ---: | ---: | ---: | ---: | ---: | ---: |
| A | 1.929 s | 0.800 s | 0.505 s | 0.249 s | 0.995 s | 0 |
| B | 1.976 s | 0.790 s | 0.498 s | 0.250 s | 0.981 s | 0 |
| Mean | **1.953 s** | **0.795 s** | **0.502 s** | **0.250 s** | **0.988 s** | **0** |

The full clipmap allocated 235.29 MiB (115.57 MiB standalone viewer output); LOD6 contributed 4,770 tiles, 32.717 M density samples, 1,834,820 vertices, and 10,272,252 indices. Logs: [run A](round4_step8_final_payload_w8_a.stdout.log), [run B](round4_step8_final_payload_w8_b.stdout.log), with [runner A](round4_step8_final_payload_w8_a.runner.log) and [runner B](round4_step8_final_payload_w8_b.runner.log). Timing varied during this continuation. Against the previous round’s 0.876 s full-clipmap mean, this pair does not show an end-to-end stream improvement; the surface-band audit pair supports only a modest step-8 versus step-4 reduction.

### W1/W8 hashes and audits

The exact step-8 executable produced matching hashes for all nine aggregate outputs at W1 and W8. Both cold hash runs had zero cache hits, emitted full payload, and retained 5,642/5,642 open route samples. Hash logs: [W1](round4_step8_final_hash_w1.stdout.log) and [W8](round4_step8_final_hash_w8.stdout.log); runner logs: [W1](round4_step8_final_hash_w1.runner.log), [W8](round4_step8_final_hash_w8.runner.log).

The W8 shape audit passed RoomFloorJoin, FloorSlopeJoin, TunnelRadius, FlatSurface, GridStair, ThinSheet, SurfaceBandFamily, FlatPatch, and DetailAudit. GridStair `relative_join_step=0.090` is below the 0.400 limit; there are zero isolated thin sheets, cave detail standard deviation is 0.8737 voxels, largest flat patch is 440 samples, and the detail audit reports supremum 4 voxels, band 6, adjacent correlation 0.9910. See [step-8 shape audit](round4_owner_coarse8_audit_w8.stdout.log). The whole-view shard audit in the W8 hash run found zero thin sheets and zero isolated small components (three boundary-touching small components).

### Six fixed captures

These six images were captured from the exact step-8 W8 executable. Every capture process exited 0. The before images are the preceding full-payload references; the field change produces small average pixel deltas but affects many shaded pixels, so these are not pixel-identical claims. The numeric comparison is [round4_step8_capture_pixel_compare.stdout.log](round4_step8_capture_pixel_compare.stdout.log), using [compare_capture_pair.py](compare_capture_pair.py).

| Fixed view and camera (metres; yaw/pitch) | Before | Step-8 capture | Changed pixels | Mean channel delta | Max channel delta |
| --- | --- | --- | ---: | ---: | ---: |
| Chamber `(-11.75,-123.25,-19.85; 0/0)` | [before](final_halflimit_after_chamber.png) | [after](round4_after_chamber.png) | 903,112 / 1,024,000 | 1.856 | 128 |

### Rejected experiments and limits

| Experiment | Result | Evidence |
| --- | --- | --- |
| Candidate mask radius 5, with global detail support | GridStair audit failed, exit 7. | [build](round4_band5_build.log), [audit](round4_band5_audit_w8.stdout.log), [runner](round4_band5_audit_w8.runner.log) |
| Radius 5 with local bound and 1.5-voxel plateau | GridStair audit failed, exit 7. | [build](round4_local_band5_build.log), [audit](round4_local_band5_audit_w8.stdout.log), [runner](round4_local_band5_audit_w8.runner.log); the later step-4 variant also failed in [this audit](round4_inner15_band5_audit_w8.stdout.log) with [runner](round4_inner15_band5_audit_w8.runner.log) |
| Exact XY plane-interpolation cache | First implementation changed flips from 570,546 to 582,493. The corrected version restored the flip count, but paired timings had no stable gain; removed. | [first audit](round4_plane_cache_audit_w8.stdout.log), [corrected audit](round4_plane_cache_fixed_audit_w8.stdout.log), [A](round4_ab_cache_a_w8.stdout.log), [B](round4_ab_cache_b_w8.stdout.log) |
| Three-at-once Perlin domain-warp helper | Audit flips matched; paired W8 timings were not faster, so scalar calls were restored. | [audit](round4_warp_x3_audit_w8.stdout.log), [A](round4_warp_ab_x3_a_w8.stdout.log), [B](round4_warp_ab_x3_b_w8.stdout.log) |
| Z-to-layer direct map | Hashes/audits matched, but paired W8 timings were no faster and tended slower; removed. | [audit](round4_layer_lookup_audit_w8.stdout.log), [A](round4_lookup_ab_local_a_w8.stdout.log), [B](round4_lookup_ab_local_b_w8.stdout.log) |
| Owner roughness interpolation at Z step 2 | Audits passed but paired W8 median was slower than local-bound baseline; step 4 then measured better and step 8 is retained. | [profile](round4_owner_coarse2_profile_w8.stdout.log), [A](round4_coarse_ab_local_a_w8.stdout.log), [B](round4_coarse_ab_local_b_w8.stdout.log) |

The step-4 to original-path A/B was too noisy to support a speedup claim: original band runs were 633 and 1,511 ms; step-4 candidate runs were 1,276 and 906 ms. All four processes exited 0, but they show no stable old-versus-new gain. AVX2 batching of the three value-noise octaves was not implemented; the narrower Perlin helper did not help. Far-mesh overlap was not tested because it can hide time in the total stream but cannot reduce the measured pre-mesh surface-band wall, and the prior overlap mixed fine bins with far work. The `--max-clip-level=8` all-strata shell proof was also not implemented: fixed captures and the LOD0 shard audit do not establish survival of every remote thin stratum, and a trustworthy proof needs an exhaustive far-shell stratum walk. LOD6 remains the default.

Builds for the final candidate and step-8 trial succeeded with `/MP8`; logs: [step-4 candidate](round4_final_candidate_build.log) and [step-8 candidate](round4_owner_coarse8_build.log). Both retain the existing French `vswhere.exe` setup diagnostic and C4838 narrowing warnings from `VoxelStrateManager.cpp`. The initial continuation profiler wrapper failed with exit 2 after a PowerShell console-title pipe error. Shell starts then returned `0xC0000142`; the machine owner identified memory pressure from a game process using about 13 GB. That prototype was removed. During the resumed work no shell-start failure recurred and no build failed. The only nonzero workload exits in this round were the three radius-5 audit runs listed above (all exit 7 on GridStair). No external viewer was closed. No commit, push, or stash was made.

## Previous-round result (superseded above)

The whole-view target remains unmet. The cold, uncached, full-payload view generated all 6,498 tiles through LOD6 in 2.135 s and 2.174 s at 8 workers. The mean process-start-to-ready time is 2.155 s. Shape compilation plus full-payload meshing averaged 1.945 s, so the generation path is about 0.945 s over the one-second mark; the process-start headline is 1.155 s over. Hashing was disabled for those timing runs. Collision cooking and the plugin’s GPU upload are not included.

The final source and measurements are in [StandaloneShapeWorld.h](../../../Source/StandaloneShapeWorld.h), [StreamingWorld.h](../../../Source/StreamingWorld.h), [StandaloneViewer.cpp](../../../Source/StandaloneViewer.cpp), [Build.ps1](../../../Build.ps1), and this report. The six current captures are linked below.

## Machine rule and headline timings

All builds and benchmark processes in this continuation ran at BelowNormal priority with affinity 0xFF00. Builds use /MP8. The final headline uses 8 workers, full UV/color/group payload, no mesh cache, and two no-hash cold runs. No current 16-worker timing was run after the reset.

| Cold whole-view run | Process wall | Shape stage | Full clipmap stream | Shape + stream | Cache hits |
| --- | ---: | ---: | ---: | ---: | ---: |
| A, 8 workers | 2.174 s | 0.828 s | 1.116 s | 1.944 s | 0 |
| B, 8 workers | 2.135 s | 0.836 s | 1.110 s | 1.946 s | 0 |
| Mean | **2.155 s** | **0.832 s** | **1.113 s** | **1.945 s** | 0 |

The process runner includes executable start and world setup. The stream stage holds the 8-worker pool at 98.9–99.4% busy; LOD6 is the long pole. The full payload allocates 235.49 MiB across the view; the standalone viewer’s geometry copy is 115.67 MiB. The 27-tile LOD0 player neighborhood is CPU-mesh-ready 23 ms after streaming starts. Collision readiness remains unmeasured.

### Stage comparison and per-LOD profile

The first column is the earlier speed-round W8 baseline from the stale report. That run used the former full-machine policy and the older viewer payload. The current column uses the restored half-load policy and emits all mesh arrays. These values show where the work moved, but are not an apples-to-apples speedup claim.

| Whole-view stage | Earlier W8 baseline | Current W8 mean | Current run range |
| --- | ---: | ---: | ---: |
| Local shapes and line bins | 57.6 ms | 53.8 ms | 53.773–53.785 ms |
| Rock intervals, packed signs, candidate axes and mask merge | 132.6 ms | 138.3 ms | 138.111–138.506 ms |
| Surface detail band | 539.0 ms | 589.8 ms | 589.734–589.833 ms |
| Far-parent shapes and spatial bins | 194.7 ms | 41.9 ms | 38.438–45.407 ms |
| Shape build | 932.3 ms | 831.7 ms | 827.765–835.705 ms |
| All-LOD full-payload mesh generation | 1,064 ms | 1,113 ms | 1,110–1,116 ms |
| Shape build + mesh generation | 1.996 s | 1.945 s | 1.944–1.946 s |

Per-LOD completion is cumulative from stream start. Each tile count and allocation figure is from the full-payload run.

| LOD | Tiles | Density samples | Complete | Full payload allocation | Viewer geometry copy |
| ---: | ---: | ---: | ---: | ---: | ---: |
| 0 | 512 | 21.952 M | 0.137 s | 33.60 MiB | 16.30 MiB |
| 1 | 448 | 19.208 M | 0.214 s | 20.37 MiB | 10.07 MiB |
| 2 | 320 | 2.195 M | 0.231 s | 6.04 MiB | 2.96 MiB |
| 3 | 208 | 1.427 M | 0.244 s | 4.23 MiB | 2.09 MiB |
| 4 | 144 | 0.988 M | 0.251 s | 2.99 MiB | 1.49 MiB |
| 5 | 96 | 0.658 M | 0.258 s | 3.17 MiB | 1.57 MiB |
| 6 | 4,770 | 32.717 M | 1.109 s | 165.09 MiB | 81.18 MiB |

LOD6 emits 1,834,816 vertices and 10,272,252 indices. It accounts for 32.717 million density samples and most of the stream time. The detailed timings are in [run A](final_full_payload_w8_a.stdout.log) and [run B](final_full_payload_w8_b.stdout.log); their process records are [A](final_full_payload_w8_a.runner.log) and [B](final_full_payload_w8_b.runner.log).

## Required mesh payload and skip verification

I inspected the actual plugin source read-only. [FVoxelMeshData](../../../../Source/VoxelForge/Public/VoxelTypes.h) contains one UV and one FColor per vertex, including dominant/neighbor biome palette, slope, and border blend channels. [BuildTileStreamSet](../../../../Source/VoxelForge/Private/VoxelWorld.cpp) enables TexCoords, Colors, and PolyGroups and copies those values into the game stream. It assigns group 0 to ground and group 1 to sky-cap ceiling; the ceiling uses material slot 1 and does not cast shadows. The mesher’s [UV/color emission](../../../../Source/VoxelForge/Private/VoxelMarchingCubesMesher.cpp) and cap ordering show why the viewer-only skips cannot be used for game output.

The current default is full payload. In the standalone copy, UV storage is FVector2f, matching the float UV sent to the game stream; this halves the UV staging width from FVector2D and saves about 20.6 MB over 2.58 million vertices. No stable speed gain appeared. FColor is already four-byte packed. The dense per-tile ceiling-column cache preserved hashes but did not improve stream time (1.099 s versus 1.098 s), so it was reverted. The final source retains the original per-column memo and emits ceiling/ground groups. I did not derive UVs or biome colors in a new shader: the game material path currently consumes TexCoord0 and the packed vertex-color channels, and plugin material/source changes were read-only in this task.

The three diagnostic skip variants were independently hash-checked at W8 over full detail, whole clipmap, and LOD0–6. Density hashes and a canonical oriented-triangle topology hash match full output in all nine outputs. The topology digest uses vertex position/normal identities, so it is insensitive to vertex IDs and triangle ordering.

| Diagnostic mode | Density equal | Serialized mesh hash equal | Oriented topology equal | Full payload hash equal |
| --- | ---: | ---: | ---: | ---: |
| Skip UV and colors | 9/9 | 9/9 | 9/9 | 0/9 |
| Skip material groups | 9/9 | 6/9 | 9/9 | 6/9 |
| Skip both | 9/9 | 6/9 | 9/9 | 0/9 |

The group skip reorders index output in three results; the geometric triangles and winding still match. The payload hash changes when UV/color arrays are omitted. These are diagnostic results only: dropping either data path changes the game’s stream contract. Combined skips took 1.533 s and 1.536 s process wall in no-hash runs, about 0.620 s below the full-payload mean, but this is not a valid game-generation result. Hash logs: [UV/colors](canonical_topology_skip_uv_w8.stdout.log), [groups](canonical_topology_skip_groups_w8.stdout.log), and [both](canonical_topology_skip_both_w8.stdout.log).

### Far-bin reserve A/B

The final far-bin reserve is 24 buckets per primitive; the axis-bin path retains 96. I rebuilt the same source with the old 2× far-bin estimate, then restored and rebuilt the final 24× source. All nine full-payload outputs matched exactly across density, mesh, payload, and topology hashes between the two reserve settings. The final 1-worker and 8-worker matrix also matches exactly.

Across two no-hash samples, the 2× build spent about 47.9 ms building far spatial bins; the 24× build averaged about 41.9 ms. Full stream time was effectively unchanged (1.1135 s versus 1.113 s), within run variation. I keep the capacity hint as a small build-stage improvement, not a whole-view speed claim. The old-estimate build and runs are logged in [build](reserve_ratio_old2_build.log), [hash](reserve_ratio_old2_hash_w8.stdout.log), [timing A](reserve_ratio_old2_timing_w8.stdout.log), and [timing B](reserve_ratio_old2_timing_w8_b.stdout.log).

## Previous-round determinism matrix (superseded above)

The final executable was rebuilt after restoring the 24× reserve. The 1-worker and 8-worker cold hash runs had zero cache hits and all 5,642/5,642 route samples open. Each of the nine output hashes below matched exactly at both worker counts, including the full payload hash.

| Output | Density hash | Geometry mesh hash | Full payload hash | Oriented topology hash |
| --- | --- | --- | --- | --- |

These checks establish repeatability on this AVX2 host across 1 and 8 workers. Cross-machine identity was not tested.

## What helped and what was rejected

Retained work from the measured speed round:

- Parallel candidate-mask merging reduced the interval/sign stage by about 14 ms in the predecessor’s 16-worker profile while preserving hashes.
- A line-local value-noise cache reuses relief noise corners along Z; its 16-worker detail-band sample fell from about 375 ms to 298 ms with exact hashes.
- A lattice-specific mesher entry point removed repeated coordinate rounding. The predecessor’s 16-worker full-detail stream moved from about 183 ms to 129–141 ms in hash runs.
- Fusing repeated rock-distance evaluation preserved hashes and lowered one 16-worker hash-run stream sample from 698 ms to 624 ms.
- Direct far capsules replaced 181,836 distant connector primitives with 16,491 while keeping all routes open and hashes stable across worker counts. They cut far-parent construction by roughly 75 ms in the predecessor’s profile.
- The compact inline/spill bin list reduced far-bin construction while keeping primitive IDs in ascending query order. A flat open-addressed table and an earlier larger inline layout were rejected because total streaming slowed.
- The per-worker vertex-map reserve remains a small allocation hint: a 32-tile LOD6 sample moved from 33.513 ms to 33.145 ms, with no stable whole-view gain.
- The current 24× far-bin capacity hint saves about 6 ms in the measured far-bin stage against 2×, with exact hashes and no measurable full-stream change.

Rejected or not tested:

- Skipping UV/colors and skipping material groups improved the standalone diagnostic viewer only. They remain off by default because the game consumes those arrays and sections.
- The dense ceiling-column cache produced no stable stream improvement and was removed.
- A thread-local last-bin cache, parallel far-bin builder, per-tile field snapshot, and per-worker edge cache did not improve the final total. The first edge-cache version removed 2,477 vertices and was rejected as a geometry change.
- Early far-tile overlap changed LOD0/1 hashes while far parents were incomplete; the path was removed.
- The multi-pass Flying Edges-style mesher, AVX2 primitive batches, forward differences, Morton page order, Bernstein bounds, six workers, and explicit coarse far surfaces were not prototyped. The measured workload has 4,770 queued LOD6 tiles and a busy worker pool, so splitting one critical tile is not the current bottleneck.

Research retained for these choices: [Abseil Swiss tables](https://abseil.io/about/design/swisstables), [Meta F14](https://engineering.fb.com/2019/04/25/developer-tools/f14/), [VTK Flying Edges](https://vtk.org/doc/nightly/release/9.7/html/classvtkFlyingEdges3D.html), the [LDAV 2015 paper](https://doi.org/10.1109/LDAV.2015.7348069), and Intel’s [Intrinsics Guide](https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html). In particular, the latter cautions that an intrinsic does not guarantee a faster instruction sequence.

## Routes, joins, shape checks, and edit latency

Every final shape build reports 5,642/5,642 passage centerline samples open and retains the native landing floors. The three fixed-view grid-stair checks pass the 0.400 threshold.

| Fixed view | Grid-stair metric | Flat-patch share | Largest flat patch | Result |
| --- | ---: | ---: | ---: | --- |
| Chamber | 0.003 | 5.0% | 433 samples | Pass |
| Tunnel | 0.028 | 5.0% | 433 samples | Pass |
| Passage | 0.205 | 8.0% | 520 samples | Pass |

The chamber, tunnel, and passage detail checks pass at a 4-voxel supremum with an 8-voxel band. Shared tunnel joins: 280 in chamber/tunnel and 240 in passage; endpoint radius and slope deltas are 0.000000 and 0.00000000. The room-floor, floor-slope, C1 floor-profile, and tunnel-radius audits pass. The whole-view level-zero shard audit covers 512 tiles and finds zero thin sheets, zero isolated small components, and four small boundary-touching components.

The crater benchmark is one transaction containing three brushes (10 m diameter, 24 m from the player): a sphere carve, rounded-box cut, and capsule rim. At 8 workers it remeshed all 14 affected tiles with zero cache hits: 12 LOD0 and 2 LOD1. Remesh time was 14 ms; edit-to-ready was 17 ms. Collision cooking is unavailable in the standalone harness.

Current audit logs: [chamber](final_audit_chamber_w8.stdout.log), [tunnel](final_audit_tunnel_w8.stdout.log), [passage](final_audit_passage_w8.stdout.log), [whole-view shard/join audit](final_shard_audit_w8.stdout.log), and [edit transaction](final_edit_transaction_w8.stdout.log).

## Previous-round six captures and visual review

All six captures were regenerated from the final full-payload executable at 8 workers and the half-load process limit.

| View | Fixed camera in metres; yaw/pitch in degrees | Current capture |
| --- | --- | --- |
| Chamber | (-11.75, -123.25, -19.85); 0 / 0 | [chamber](final_halflimit_after_chamber.png) |
| Tunnel | (-11.75, -123.25, -19.85); 90 / 0 | [tunnel](final_halflimit_after_tunnel.png) |
| Passage | (-39.19, 6.27, -28.51); 63 / 0 | [passage](final_halflimit_after_passage.png) |
| Far view | (-11.61244, -118.2212, -19.8452); 0 / 0 | [far](final_halflimit_after_far.png) |
| Passage-floor close-up | (-39.19, 6.27, -25.51); 63 / -25 | [floor close-up](final_halflimit_after_passage_floor_closeup.png) |
| Tunnel bend | (-198.97, -99.57, -45.58); 33.59 / 23.17 | [bend](final_halflimit_after_tunnel_bend.png) |

Five captures are byte-identical to the preceding rebuilt set. The passage view differs in 662 of 1,024,000 pixels, with a maximum channel delta of 97; side-by-side inspection shows the same framing and visible geometry. Against the owner images, the visual gap remains: the chamber still has broad smooth ceiling/floor areas, the tunnel has repeated relief bands, the passage keeps a horizontal shelf and dark opening instead of the owner’s layered profile, and the far view lacks the owner’s larger connected forms. The look is not a match.

The four owner-comparison references remain [chamber](../final/chamber_fixed_owner.png), [tunnel](../final/tunnel_fixed_owner.png), [passage](../final/passage_fixed_owner.png), and [far view](../final/far_owner.png). The earlier fixed captures are in [round 2](../round2/REPORT.md).

## Previous-round build limits and failed invocations

The final build is [final_halfload_build.log](final_halfload_build.log). It succeeded with /MP8. The build and workload processes ran BelowNormal on affinity 0xFF00. The recurring French vswhere.exe setup diagnostic still appears, followed by a successful compile; six existing C4838 narrowing warnings remain in VoxelStrateManager.cpp.

Failures during this continuation, with corrected work preserved:

- The first dense ceiling-column cache build used CellsPerAxis before its declaration. That build failed; the declaration was moved before use, the retry built, and the cache was later removed after a no-gain timing result.
- One audit runner call named StandaloneViewer.exe, which does not exist. RunMachine stopped before launching a child; the corrected executable is VoxelForgeStandalone.exe.
- The first six-capture wrapper assembled --camera and --capture arguments as separate strings. Each process exited 2 on Invalid --camera value before opening a viewer. The arguments were corrected and all six final captures completed with exit code 0.
- An earlier wrapper call used a relative Tee-Object path after Build.ps1 changed directories. Its log redirection failed; the build was checked and rerun with an absolute log path.
- Older exploratory audit and optimization failures from the look round remain documented in [round 2](../round2/REPORT.md) and its retained logs.

No external viewer was closed. No commit, push, or stash was made. All source, report, and capture edits are within Standalone.
