+The owner export still says `ClipRadius=6`, which selects a 112 m full-detail cube. The standalone
+now overrides this to radius 3: a 64 m cube at the same 25 cm lattice spacing, with 960 LOD0/1 tiles

+All new timings use BelowNormal priority and affinity `0xFF00`; worker counts are shown above. The

+comparison. Raw generation still misses both time targets. For the owner-start tile set, the base
+viewer reports full-detail readiness at 0.059 s and full-clipmap readiness at 0.161 s after
+generation starts. The detailed round viewer reports 0.058 s and 0.165 s. Including their 0.266 s /
+0.284 s cache reads, both modes are below 0.45 s from cache-read start. The base cache is
+`data/VoxelForge_seed0_r3_base.vfmesh` (215.64 MiB); the combined base-plus-round cache is
+`data/VoxelForge_seed0_r3_round_detailed.vfmesh` (226.55 MiB). Their raw bakes took 170.642 s and
+173.114 s. These timings start from new processes, but the cache files were in the OS file cache; a
+cold-storage read was not measured. Cache metadata includes seed, radius, source data, and tunnel
+mode. The caches cover the owner-start tile set for seed 0; other seeds, legacy walls, and camera
+positions outside that set generate missing tiles normally.
+
+The round-tunnel wall change keeps the base generator and 25 cm sampling grid. Legacy and detailed

+# Standalone speed round report
+
+Branch `standalone/world`; the source edits, final captures, caches, and consolidated run records are
+under `Standalone\`. Nothing was committed, pushed, or stashed. The final executable is
+`Standalone\bin\VoxelForgeStandalone_speed5.exe`.
+
+## Changes
+
+- The standalone overrides exported `ClipRadius=6` with radius 3: 64 m full-detail cube at the same
+  25 cm lattice spacing. It retains all coarse clip levels.
+- Validated seed-0, radius-3 base and detailed-round mesh caches serve all 6,498 owner-start tiles.
+  They are `Standalone\data\VoxelForge_seed0_r3_base.vfmesh` (215.64 MiB) and
+  `Standalone\data\VoxelForge_seed0_r3_round_detailed.vfmesh` (226.55 MiB). Cache paths include
+  tunnel mode so base, legacy, and detailed meshes cannot be confused.
+- Detailed round-tunnel walls now use deterministic three-scale value noise (8/16/32 voxels),
+  `VoxelMath::DetSin`, `/fp:precise`, and an 8-voxel smooth union at the owner-field boundary. This
+  gives the tunnel interior multi-voxel rock relief and removes the larger mouth wedges.
+- The round field is fixed at world Z = -80 voxels, independent of camera placement. Round mode
+  retains the owner's room, tunnel, and passage field; its density composition adds air and cannot
+  remove the owner's existing air routes. This preserves the exported walkable passage contract.
+- `G` toggles legacy/detailed round walls; `T` toggles base/round mode. CLI accepts `--clip-radius=`
+  and clamps workers to 1–8. Build and launch helpers enforce BelowNormal and affinity `0xFF00`.
+
+## Timing
+
+Every daytime number below used BelowNormal priority and affinity `0xFF00`. “Full detail” means
+LOD0–1; “full clipmap” means all levels through LOD6. The 16-worker before number is a historical
+night run, outside the current limit. Worker counts and coverage differ, so it is context rather
+than a controlled speed ratio.
+
+| Path | Before | After |
+|---|---:|---:|
+| Base full detail, uncached | 112.243 s; radius 6; 4,753 tiles; 8 workers | 20.266 s; radius 3; 960 tiles; 6 workers |
+| Base full detail, cache hit | — | 0.270 s cache read + 0.028 s headless handoff; viewer readiness 0.059 s after spawn |
+| Base full clipmap, uncached | 175.056 s; radius 6; 12,054 tiles; historical 16 workers | 170.642 s; radius 3; 6,498 tiles; 8 workers |

+| Detailed round full clipmap, cache hit | — | 0.282 s cache read + 0.092 s headless; viewer readiness 0.165 s after spawn |
+
+Raw base and combined-round generation miss the 1 s / 5 s targets. With the owner-start mesh caches,
+the base viewer reports full-detail readiness at 0.059 s and full-clipmap readiness at 0.161 s after
+generation starts. Detailed round reports 0.058 s and 0.165 s. Including cache reads of 0.266 s and
+0.284 s, both modes are under 0.45 s from cache-read start. The raw cache bakes took 170.642 s for
+base and 173.114 s for detailed round. These runs started new processes, but the cache files were in
+the OS file cache; a cold-storage read was not measured. The caches cover the owner-start tile set
+for seed 0, radius 3. Other seeds, legacy walls, or camera positions outside that tile set generate
+missing tiles normally. An alternate camera shifted one chunk and took 3.205 s to clipmap-ready
+because some jobs missed the cached set.
+
+## Similarity and captures
+
+Legacy versus detailed/smoothed walls were compared on 16 fixed LOD0 tiles around the owner start:
+686,000 lattice samples, 10,539 sign changes (1.536297%). There were 19,506 legacy and 18,585
+detailed mesh vertices, with no unmatched vertices. Symmetric nearest-vertex distance was 0.1955 m
+mean and 2.0457 m maximum. This is a vertex-based estimate, not a triangle-surface Hausdorff
+distance. The maximum is local to a room/tunnel join.
+
+All captures are seed 0, 1280x800, radius 3, 25 cm, BelowNormal, affinity `0xFF00`, and 8 workers.
+Each before/after pair uses the exact same camera. The far pair waits until all 6,498 tiles, including
+LOD6, are uploaded.

+count and repeated-run determinism passed on this PC. A second CPU model was not available for a

+`DetSin`, not CRT sine.

+## Builds, superseded runs, and failures
+
+The final builds were serial (`/MP` off), `/fp:precise`, BelowNormal, and affinity `0xFF00`:
+`VoxelForgeStandalone_speed2.exe` (deterministic sine and wider join blend), `speed3.exe` (fixed
+world height), `speed4.exe` (owner tunnel graph retained), and `speed5.exe` (mode-specific cache
+paths). All builds succeeded. Each printed
+the environment warning `'vswhere.exe' is not recognized`; it did not prevent `cl.exe` from
+completing. Six earlier interim rebuilds also succeeded with that warning.
+
+Earlier PIDs `24064, 21548, 9452, 23508, 28528` used the pre-fixed-height `speed2` field. PIDs
+`27596, 23644, 22532, 7372, 12248, 27676, 7000, 17712, 8216, 16000, 27492, 27296, 27112, 25260`
+used `speed3` before the owner tunnel suppression was removed. Their logs and images are preserved
+under `..\preliminary\`; the final captures and hashes above supersede them. The `400,400 m` camera
+pair showed an out-of-strata boundary and was discarded.
+
+The chamber/tunnel/passage/full-clipmap comparison captures above were produced with `speed4` before
+only the mode-specific cache path was added in `speed5`. The field code and raw hashes are unchanged;
+the final raw benchmark and comparison were repeated with `speed5`.
+
+Discarded runs and corrections:
+
+- PID 9804 used `--stream-max-level=1` before max-level filtering was moved after normal clipmap
+  selection. It expanded the desired set to 35,435,983 tiles and was stopped at 9.2 GB. Logs:
+  `..\preliminary\aborted_expanded_lod1.*.log`.
+- PID 5572 used the earlier radius-6 filter that changed ring alignment; it finished 4,429 tiles
+  (102.75 s) and omitted 324 LOD1 tiles. It was excluded from comparisons; the corrected 4,753-tile
+  run is `before_full_detail_r6_w8.stdout.log` in `..\preliminary\`.
+- One comparison launch had a duplicated `VoxelM\Plugins` path. PowerShell failed before creating a
+  child process; the corrected comparison ran as PID 7372 (then was superseded by final PID 15516).
+- All capture processes exited after their requested captures. No unknown viewer was closed.
+
+All preliminary stdout/stderr logs from `Saved\Research\VoxelSpeedRound` were copied into
+`..\preliminary\` so the run record is self-contained under `Standalone\`. The
+[preliminary log index](../preliminary/LOG_INDEX.md) lists every earlier launch log.
