core: coarser smooth-route tolerance + shell support bound (L119, evaluator v224)

Chord error 2.5 -> 10 cm, shell work skipped outside the 0-0.75 m band. Sweep pairs -39%, prepare -60%, near-ready 3-8% faster than L115 but still +13..+22% vs L109. Floor offset 7.88 mm; captures match L115 by eye; fast tier, walk audits, Clang/GCC W1/W8/W12 determinism green. Not for merge yet.

+# Linux119 — smooth half-pipe speed
+
+## Result
+
+The route now uses a 10 cm chord-error tolerance (was 2.5 cm); the 8 m spacing cap is unchanged. The evaluator is version 224. Output changed, but Clang/GCC and W1/W8/W12 hashes match.
+
+L119 improves on L115, but misses the L109 near-ready target in all eight stratum/worker cells: **13.3–22.0% slower than L109**. It is 2.8–7.7% faster than L115 at near-ready. Whole-view readiness remains 6.5–12.3% slower than L109.
+
+Five interleaved L80 measurements per cell followed one warmup per version. The timing gate recorded 1-minute load 0.82 and 98.7% CPU idle. Headless runs used CPUs 0–11, the 6 GiB address-space limit, and a 1,740 s timeout.
+
+| Stratum | Workers | Near L109 / L115 / L119 (s; Δ vs L109) | Whole view L109 / L115 / L119 (s; Δ vs L109) |
+| --- | ---: | ---: | ---: |
+| S0 | 8 | 0.761 / 0.929 / 0.880 (+15.6%) | 1.742 / 1.927 / 1.860 (+6.8%) |

+
+## Designs and work
+
+Two designs were built together. Before building, the fourfold chord tolerance increase predicted about half as many curvature-limited route segments (segment count scales roughly with the inverse square root of the error tolerance). The shell support bound was expected to skip most shell calculations: only flattened distances in the 0–0.75 m shell band can contribute, with a 1-subvoxel guard. L118 had 48.93M W8 sweep pairs and 39.3M sampled smooth-min calls.
+
+| Stratum | W8 LOD0–2 pairs L109 / L115=L118 / L119 (M) | Exact fallbacks L109 / L115=L118 / L119 (M) | Segment visits L109 / L115=L118 / L119 (M) | Prepare ms L118 → L119 | L119 shell-support skips |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| S0 | 3.36 / 7.56 / 4.55 | 0.241 / 0.413 / 0.652 | 1.19 / 3.41 / 4.68 | 467 → 185 | 3.73M (81.9%) |
+| S1 | 6.19 / 16.22 / 9.69 | 0.369 / 0.719 / 1.114 | 1.91 / 7.60 / 9.25 | 919 → 361 | 8.05M (83.1%) |
+| S2 | 6.15 / 15.52 / 9.28 | 0.315 / 0.634 / 0.986 | 1.66 / 6.88 / 8.34 | 848 → 345 | 7.69M (82.8%) |
+| S3 | 4.09 / 9.63 / 5.88 | 0.074 / 0.131 / 0.203 | 0.48 / 1.41 / 2.19 | 567 → 235 | 4.76M (80.8%) |
+
+L119 reduced pairs 39–40% versus L115/L118, and summed W1 prepare time fell 59.8% (2.801 s to 1.125 s). Exact fallbacks are 55–58% higher than L115/L118 and visits are 21–56% higher. Those extra fallback scans are the likely remaining readiness cost. L119 prepare time is timed directly; L109/L115 prepare time was not separately instrumented.
+
+## Quality and verification
+
+- Floor root offsets: 51 samples at each of 9 stations; maximum 7.884 mm versus L115’s 7.849 mm.
+- Fast tier: PASS in 277.9 s. Walkability, floor/mouth profiles, open-air shell, ripple, naturalness, and grade audits passed; no geometry threshold was relaxed.
+- Determinism: all 18 Clang/GCC W1/W8/W12 hash runs matched for owner4 surface world and both owner2 canonical recipes. Owner2 v224 baselines were added. Source stamp: `9a592cb548c6768c8c25723f4168f65da9645068cb67dcb317e91f707e7d41df`.
+- Captures: 23/23 L115 view names and camera poses rendered with the L119 binary; 19 pass and 4 low-contrast-visible. L115 had 18 pass and 5 low-contrast-visible. [Compare all views side by side](captures/COMPARE.html); [L119 capture index](captures/L119/INDEX.md).
+- Linux VFHostEditor: PASS, 27/27 actions in 70.98 s with `-NoUBA -MaxParallelActions=4`. Unreal ran without `prlimit`; three existing RealtimeMesh deprecation warnings remain.

+# L119 captures (L115 view set)
+
+The 23 L115 camera poses were rendered with the L119 binary. Floor anchors require an upward normal alignment of at least 0.85, target-to-floor distance at most 0.25 m, and camera-to-floor distance between 2.0 and 3.2 m. Open-air sections have outside and interior wall close-ups at 4 m.
