research: L118 passage-tile designs (hash-exact, no readiness gain; kept as patch)
Tagged the passage bucket: per-tile prepareSweptTubeBase dominates (0.47-0.92 s summed per view), smooth-min second. Segment lower-bound pruning (-17% pairs) and deferred fallback floor work stayed hash-exact but moved near-ready <3%. Still +17..+26% vs L109.

# Linux118 — passage tile cost
|
||||||
|
|
||||||
|
## Result
|
||||||
|
|
||||||
|
The L115 output is exact: owner4 hashes match at W1/W8/W12 under Clang and GCC. Walk audits passed, and the fast tier passed with 259 checks plus 5 diagnostic-only baseline comparisons.
|
||||||
|
|
||||||
|
The near-ready target was not met. The final candidate is 17.2–25.7% slower than L109 across the eight W8/W12 cells; whole-view readiness is 9.4–13.9% slower. Both designs leave readiness close to L115.
|
||||||
|
|
||||||
|
## Field tags
|
||||||
|
|
||||||
|
One W1 probe per stratum, summed over LOD0–2 passage-feature tiles. `SmoothMinDistance` time is estimated from 1/128 sampled calls. Point time contains `CachedColumn`; cache read time is inside `CachedColumn`, so those columns overlap.
|
||||||
|
|
||||||
|
| Stratum | Feature tiles | Prepare ms | Smooth-min calls / ms est. | Point / CachedColumn ms est. | Shared reads ms est. (initial / locked) |
|
||||||
|
| --- | ---: | ---: | ---: | ---: | ---: |
|
||||||
|
| S0 | 158 | 467 | 7.14M / 137 | 404 / 226 | 24 / 4 |
|
||||||
|
| S1 | 195 | 919 | 15.60M / 289 | 0 / 0 | 0 / 0 |
|
||||||
|
| S2 | 187 | 848 | 13.93M / 249 | 0 / 0 | 0 / 0 |
|
||||||
|
| S3 | 182 | 567 | 2.62M / 49 | 0 / 0 | 0 / 0 |
|
||||||
|
|
||||||
|
The Heightfield2D/cache tags occur in S0; the other three strata do not use that path in these views.
|
||||||
|
|
||||||
|
## Designs and passage counters
|
||||||
|
|
||||||
|
Design 1 added a conservative segment-to-sample lower bound in `prepareSweptTubeBase`. It skips distance, floor, and shell work when a segment cannot improve the sample. Hashes stayed exact. It pruned 17–18% of candidate pairs, but the readiness matrix remained near L115.
|
||||||
|
|
||||||
|
Design 2 deferred floor-profile interpolation in exact fallbacks until a segment could improve the nearest route or floor result. It also stayed hash-exact, with only a small timing change. Restricting fallbacks to prepared feature spans changed hashes, so that restriction was removed.
|
||||||
|
|
||||||
|
W8 passage-feature tile totals, averaged over two profiles per stratum. L118 pairs show evaluated plus bound-pruned counts; their sum equals L115's candidate-pair total.
|
||||||
|
|
||||||
|
| Stratum | Sweep pairs: L109 → L115; L118 evaluated + pruned | Fallbacks: L109 → L115 → L118 | Visits: L109 → L115 → L118 |

## Readiness

Five interleaved measured runs per version, stratum, and worker count, after one warm-up per version. Values are median seconds: near LOD0–2 / whole view.

The timing gate recorded one-minute load 0.65 and 99.2% CPU idle. Each headless run used CPUs 0–11, the 6 GiB address-space limit, and a 1,740 s timeout. Design 1 timings are preserved in `Saved/Linux/l118/timing-design1/`; final timings are in `Saved/Linux/l118/timing/`.
|
||||||
|
|
||||||
|
## Unreal and workspace
|
||||||
|
|
||||||
|
The post-timing Linux `VFHostEditor` build passed (27/27 actions, 71.13 s) with `-NoUBA -MaxParallelActions=4`; it compiled `VFCore_Core_src_VoxelForgeCore_cpp.cpp`. Unreal ran without `prlimit`. Three existing RealtimeMesh deprecation warnings remain.
|
||||||
|
|
||||||
|
Work stayed on `wip/l111-halfpipe-spline` at `c2b8d39`. No commit, push, or stash was made. Logs and summaries are under `Saved/Linux/l118/`.
