Fr0zkaandClaude Opus 5.5 ff52c9b576 proto: liminal looks - pool rooms, backrooms grid, staircase to nowhere, terraced hills (L161)

Stamp vocabulary v7 (opt-in fillBox, carveBox, fillSteps; carveArch reused); flat-field liminal stamp fixtures; capsule
walk audit with doorway-width gate (1.2 m control fails as expected). Clang/GCC W1/W8/W12 identical; owner canonical
hashes unchanged; fast tier 273/273. Terraced wide view not yet legible.

L161 — More liminal looks

Look	Eye height	Wide
Pool rooms
Backrooms grid
Staircase to nowhere
Terraced hills

Result

Four standalone SurfaceWorld fixtures resolve from the shared stamp vocabulary. They use repeated rooms and basins, a doorway grid, a freestanding stair and arch, and nine stepped ridges. This round authored no inter-strate passages or owner content.

Changes

Stamp vocabulary v7 adds fillBox, carveBox, and fillSteps; the existing carveArch is reused. The new kinds are opt-in.
Added a flat-field liminal stamp-fixture override and a capsule walk audit with doorway-width gates. The audit checks support, collision, grade, and authored opening widths.
Fixtures contain 275 pool-room stamps, 129 backrooms stamps, 4 staircase/arch stamps, and 18 terrace stamps.

Verification

Clang 19 and GCC 14 builds passed with FP contraction off. Both binaries carry source stamp 8e9e114c1357.
Each fixture matched across Clang/GCC at W1, W8, and W12: manifest, resolved-layout identity, and tile hashes were identical in all six cells.
Positive capsule audits passed. Pool doorways measured 7.2 m, backrooms doorways 4.0 m, and the arch opening 10.0 m. The narrow 1.2 m backrooms control failed the 1.5 m minimum as expected. The terrace walk had zero blocked samples, unsupported samples, or grade failures.
All eight 1600×900 captures passed image quality checks; files are 25.3–58.4 KB. Capture and audit logs are under Saved/Linux/l161/logs/.
Fast tier passed: 273 checks in 346.6 s. Both owner generators matched their pinned L130/v227 canonical baselines exactly (12/12 rows), and W1/W12 signatures matched. Summary: Saved/Linux/l161/fast-tier/fast-summary.json.
git diff --check passed. No Unreal Source/ files changed; no Unreal build or medium/full verification tier was run.

Remaining risk

The captures show untextured geometry with simple fog. The terraced wide capture uses clip radius 3 and max LOD 1 to stay within the standalone shape-build bound, so the long-range horizon read still needs an art review.
