Owner shapes compile per stratum on the Core parallel scheduler and merge in owner-layout order; far-parent ellipsoids/connectors generate in parallel and merge canonically; 512-unit far bins. Base compile 239 -> 203 ms, far-parent build 128 -> 33 ms. Near-ready @W12: SW 0.84 -> 0.75, FI 1.51 -> 1.42, TN 1.38 -> 1.30, VS 0.92 -> 0.85 s. All hashes equal L104 (Clang/GCC W1/W8/W12). Fast tier PASS; Linux UE builds; 6/6 Unreal arrival traces pass. R45 (read-only, owner's "are we overcomplicating?"): next simplifications = tunnel floor/mouth support inside the bounded passage field; boundary bands once per XY column; certified early SW tiles.

Linux 105 — serial startup phases
Changes and phase timings
Owner-shape compilation now runs by stratum on the core parallel scheduler. Results are merged in owner-layout order. Far-parent ellipsoid and connector generation also uses parallel workers, then merges in canonical order. The far-parent spatial index uses larger 512-unit bins; the exact primitive predicate and insertion order remain unchanged. LOD2 still waits for far parents.
| Phase | L104 median | L105 median | Change |
|---|---|---|---|
| Base-shape compile | 239.1 ms | 202.8 ms | −15.2% |
| Far-parent build | 128.5 ms | 33.4 ms | −74.0% |
L105 base-shape substage timers across FI/TN at W8/W12:
| Substage | Range |
|---|---|
| Owner shapes (parallel wall; aggregate worker time) | 22.1–23.8 ms; 47.8–51.7 worker-ms |
| Owner bins / visual detail prep | 1.18–1.40 ms / below 0.001 ms |
| Packed intervals/signs | 23.7–25.9 ms |
| Passage prep | 10.1–11.7 ms |
| Candidate sweeps | 23.3–27.6 ms |
| Surface/detail band | 54.0–93.2 ms |
| Sign-edge repair | 9.6–10.7 ms |
| Route validation | 26.5–29.3 ms |
| Far-parent geometry (parallel wall; aggregate worker time) | 2.4–2.7 ms; 16.2–18.2 worker-ms |
| Far shared fields / bin rebuild | 4.0–4.3 ms / 16.7–18.3 ms |
The timeline tracks streaming tile workers. In L104 they were about 99.99% idle during the 232–251 ms base compile, 99.4% busy during LOD0–1, and idle throughout the 110–144 ms far-parent phase. In L105 the tile pool remains 99.96–99.99% idle during base compile while the separate core parallel scheduler performs owner-shape work (22–24 ms wall from 48–52 worker-ms). LOD0–1 is 99.2–99.6% busy; far-parent takes 33–34 ms with the tile pool idle; LOD2 is 92.8–95.9% busy. Full event data and the utilization breakdown are in Saved/Linux/l105/timeline/ (analysis.json, utilization.csv, and four logs).
L80 readiness pairs
Sixteen warmups total, then three interleaved measured runs per build and cell. Each cell has complete near and whole-view tile sets; values are medians in seconds, L104 → L105.
| View | W8 near | W8 whole | W12 near | W12 whole |
|---|---|---|---|---|
| SW | 0.840 → 0.744 (−11.4%) | 1.957 → 1.835 (−6.2%) | 0.839 → 0.746 (−11.2%) | 1.878 → 1.762 (−6.2%) |
| FI | 1.597 → 1.556 (−2.6%) | 2.594 → 2.516 (−3.0%) | 1.514 → 1.420 (−6.2%) | 2.438 → 2.338 (−4.1%) |
| TN | 1.516 → 1.455 (−4.0%) | 2.475 → 2.341 (−5.4%) | 1.384 → 1.301 (−6.0%) | 2.228 → 2.140 (−3.9%) |
| VS | 1.085 → 1.024 (−5.6%) | 2.016 → 1.920 (−4.8%) | 0.917 → 0.849 (−7.4%) | 1.774 → 1.703 (−4.0%) |
Exactness and verification
- All 24 hash runs passed: SW/FI/TN/VS × Clang/GCC × W1/W8/W12. Every tile hash and whole-view hash matched L104 and the Clang W1 reference.
- Candidate source stamp:
c6b2740c67bc96252ba57eb303b40d97d3c3451fcb4f1daed7bae773351681ab. - Fast tier: PASS, 278.4 s.
- Linux Unreal build: Succeeded with
-NoUBA -MaxParallelActions=4; it compiled the modified core shim. Build log:Saved/Linux/l105/unreal-build.log. - Three FI and three SW Unreal arrival traces: 6/6 passed, exit 0. FI settled 1,216 near tiles in 1.545–1.562 s from first admission; SW settled 1,430 in 1.285–1.317 s. Unreal ran with
taskset -c 0-11, withoutprlimit. - Parallel full-bin assembly variants were retired after regressions. The retained serial exact bin rebuild measured 16.7–18.3 ms with the 512-unit far bins.
