Floor ribs are present in L109/L112/L113 rock tunnels too: the floor height comes from the nearest segment, so it jumps (up to 5.9-7.3 cm) where the nearest segment switches. v222 reduces them; faint ribs remain. Quiet-machine timing (load 0.64): near-ready 9-17% slower than L109 (FI W12 0.95 -> 1.10 s); candidate totals ~5x L109. Fast tier FAIL: 2 SW wall-shell probes of 31,381 read host air. Walk/grade audits pass; Clang/GCC deterministic; UE builds. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016dhxM43dnWvUu2B5Ph1iG1

# Linux 114 — floor profile and speed
|
||
|
||
Evaluator version: **222**. Worktree remains on `wip/l111-halfpipe-spline`; no commit was made.
|
||
|
||
## Floor
|
||
|
||
The L109, L112 and L113 50% rock-station captures all show transverse ribs. In v222, tube-body selection uses round distance and the floor profile is selected separately by nearest centerline. The passage now supplies a signed metric distance outside its void instead of inheriting the host field's saturated deep-rock value.
|
||
|
||
At the L114 passage 1–2 rock-station column, the raw source value at the floor was saturated at `-256.160522 m`; the composed floor value was `-0.007221 m`. The vertical profile is nearly linear:
|
||
|
||
| Height from planned floor (m) | -0.50 | -0.25 | -0.10 | 0.00 | +0.10 | +0.25 | +0.50 |
|
||
|---|---:|---:|---:|---:|---:|---:|---:|
|
||
| Density (m) | -0.5064 | -0.2568 | -0.1070 | -0.00722 | +0.0926 | +0.2423 | +0.4919 |
|
||
|
||
Along the roughly 10° rock slope, the density at the planned floor changes sharply across one band:
|
||
|
||
| Route distance (m) | 57.495 | 57.795 | 57.895 | 57.995 | 58.095 | 58.295 | 58.495 |
|
||
|---|---:|---:|---:|---:|---:|---:|---:|
|
||
| Density at planned floor (m) | +0.00724 | +0.00726 | +0.00724 | -0.07260 | -0.05748 | -0.02614 | +0.00667 |
|
||
| Zero-crossing offset (m) | -0.00722 | -0.00720 | -0.00721 | +0.07234 | +0.05730 | +0.02607 | -0.00665 |
|
||
|
||
Across 51 samples, the maximum offset is 5.9 cm on passage 0–1 and 7.3 cm on passage 1–2. The L114 rock-floor close-up shows a large reduction from L109/L112/L113, but faint transverse ridges remain. The floor is improved, not fully smooth yet. Full probes: `Saved/Linux/l114/audit-owner-clang.log`.
|
||
|
||
## Speed
|
||
|
||
Timing was deferred until load fell from 5.46 to 0.69; the runner's gate measured **0.64** immediately before the batch. It ran five interleaved L80 samples per cell across all four strates. Values are median seconds, `LOD0–2 near-ready / whole-view-ready`, ordered L109 → L113 → L114.
|
||
|
||
| Strate | W8 near / whole | W12 near / whole |
|
||
|---|---|---|
|
||
| SW | 0.778 → 0.851 → 0.849 / 1.808 → 1.874 → 1.861 | 0.802 → 0.877 → 0.936 / 1.751 → 1.872 → 1.912 |
|
||
| FI | 1.177 → 1.271 → 1.380 / 2.201 → 2.255 → 2.450 | 0.946 → 1.122 → 1.102 / 1.816 → 2.012 → 1.993 |
|
||
| TN | 1.112 → 1.201 → 1.211 / 1.977 → 2.109 → 2.166 | 0.959 → 1.090 → 1.074 / 1.786 → 1.925 → 1.918 |
|
||
| VS | 1.019 → 1.149 → 1.156 / 2.065 → 2.308 → 2.263 | 0.950 → 1.074 → 1.098 / 1.963 → 2.131 → 2.166 |
|
||
|
||
L114 is 9–17% slower than L109 at near-ready and 3–11% at whole-view. L114 candidate totals match L113 and exceed L109: SW `3102 vs 583`, FI `5384 vs 1036`, TN `3701 vs 869`, VS `2197 vs 644` feature/route candidates across the profiled tiles. The L77 W8 census estimates median extra worker CPU of `0.71 s` at LOD0–2 and `0.88 s` whole-view across the four cameras. The largest added buckets are broad `other` work (`+0.72 / +0.60 s`) and passage work (`+0.21 / +0.40 s`); composition-bands work is flat or lower. L77 values are weighted sample estimates, not direct phase timers.

## Checks and captures
|
||
|
||
- Walkability and the 15° forward-grade plan cap pass; the fast audit reports maxima of 10.48° (SW) and 10.01° (FI).
|
||
- Clang/GCC hashes match at W1/W8/W12 for all four strates and both two-strate recipes: 18 runs, source stamp `735079f…`.
|
||
- Fast tier is **FAIL**: the SW owner audit reports 2 wall-shell violations in 31,381 probes. Both samples return the same positive host density (`+35.742 m`, `+35.578 m`) where the shell audit expects solid. This remains unresolved after the two floor geometry designs.
|
||
- Linux `VFHostEditor` build succeeded in 80.6 s with `-NoUBA -MaxParallelActions=4`; Unreal was not run under `prlimit`.
|
||
- The [capture index](captures/INDEX.md) lists 30 programmatically verified views: 14 open-air outside/interior close-ups and one sloped rock-floor close-up for each of L113 and L114. Four low-contrast open-air images are flagged as geometry-visible. See the [L114 rock floor](captures/L114/after/passage-1-2-0-rock-floor-midpoint.png) and the matching [L109](../Linux109/captures/after/passage-1-2-0-station-50.png), [L112](../Linux112/captures/after/passage-1-2-0-station-50.png) and [L113](../Linux113/captures/after/passage-1-2-0-station-50.png) station captures.
