Fr0zkaandClaude Opus 5.5 6cd9e4da76 proto: liminal pass 2 - hills to the horizon, swept road over a cloud floor, pillar grid (L142)
Captures stream LOD0-8 (hills repeat at 80 m to the horizon). Road: cubic swept solid deck, 376.8 m, 8 m wide, max
12.06 deg, 17 supports, cloud floor ~45 m below; walk audit 0 blocked/unsupported, 300 m negative control fails as
expected. 15x15 identical pillar grid at 76 m. Owner canonical hashes unchanged; fast tier, Clang/GCC green.

## Result
The wide hill capture shows the validated 80 m repeating profile continuing across the horizon. The capture now streams LOD 0–8; the profile period and validator are unchanged.
The road is a cubic swept path made from overlapping solid deck segments, not a chain of platform stamps. The earlier platform chain produced top steps; the swept deck passes the surface-sampled walk audit. Its wide view is capped at LOD 2 to keep the deck legible, so that frame shows a local section; the full route length is measured by the audit.
The R47 addition is a 15×15 grid of identical pillars, spaced 76 m apart across a 1,064 m span. The monolith eye and wide views are retained as the first liminal slice.
## Measurements
- **Road:** 376.827 m horizontal path length, 8.000 m width, and 12.061° maximum sampled surface grade against the 15° limit. The deck rises and falls along the cubic profile. It has 17 supports at about 24 m spacing; the flat cloud floor is 44 m below the deck centerline (about 45 m below the walking surface), with pale fog in both views.
- **Walk audit:** 901 surface stations at no more than 0.5 m spacing; 56,763 capsule samples; 0 blocked samples, 0 unsupported samples across 5,871 support probes, 0 grade failures, and 0 missed surface probes. The 180 m short-road control measured 210.341 m and failed the 300 m gate as expected.
- **Capture quality:** all eight fixtures/views passed the image-quality gate at 1600×900. Hills and pillars stream through LOD 8; road eye and wide views use caps 3 and 2 respectively.
- **Determinism:** the monolith, hills, road, and pillar fixtures each matched across Clang and GCC at W1, W8, and W12 (six compiler/worker cells per fixture), on source stamp `72f239e9534faa27e3796fe29207403b190558403841aeebc87d8e75e98e34c7`.
## Checks
- Clang 19 and GCC builds passed with floating-point contraction off, four build jobs, and the L142 source stamp.
- `Standalone/Tools/verify/verify.py fast --out Saved/Linux/l142 --overall-timeout 1740` passed. Both current owner fixtures produced all 12 canonical hash rows matching the pinned L130-v227 baseline; W1 and W12 also matched each other.
- The fast summary retains non-gating differences against older L46/L53 diagnostic baselines; the current pinned L130 canonical checks pass.
- The L142 capture runner passed the walk audit, the short-road negative control, all four determinism comparisons, and all eight image-quality checks. Final logs are in `Saved/Linux/l142/logs/`.
- No Unreal build or performance timing matrix was run. No Unreal `Source/` files changed. The inherited single-run near-ready timing step was removed from this picture-and-geometry runner rather than treated as a timing result.
## Remaining limits
The road wide capture frames a local section at LOD 2 to retain a continuous deck; the 376.827 m length is established by the full-route walk audit. Captures use the standalone Linux renderer rather than an Unreal viewport.
Changed Unreal `Source/` files: none.
