Fr0zkaandClaude Opus 5.5 4e64b75044 feat(core): slab + sparse motifs, slice 1 -- flat field, monolith, platform at 0.52 s (L56); research R25

Motif vocabulary v3: version-1 records keyed by (seed, strate, stable ID) with route keepouts, band
clearance and pairwise spacing. A rounded capped-cylinder monolith (r 1.4 m, 24 m tall) and a rounded-box
plinth, smooth-unioned into a flatField floor with a 0.55 m geometric rounding (measured fillets 0.73-1.17 m).
Exact radial/box interval bounds, a BVH, isTileShapeFree aware (0 brute-force misses, false-proof controls
rejected). Final-field route passes; whole-surface audit covers foot, cap and platform edges. Cold whole
view 0.524 s. Owner world unchanged. fast/medium/full PASS (Clang and GCC).
Research R25 (self-checked): FloatingIslands LOD0 column cache conflicts.

Raw Blame History

L56 — R24 slice 1: slab + sparse motifs

Result: PASS. The native family adds one flatField stratum with one monument and one low platform. Fins remain on hold.

Records and field

Motif vocabulary v3 resolves two version-1 records with placement keyed by (seed, strate, stable_id), route keepouts, band clearance, and 15 m pairwise spacing. Fixture seed is 0; both records attach to the floor at Z = -529.600 m.

motif/monolith-01-v1: rounded capped cylinder, radius 1.4 m (within R20 profile 0.8–2 m), height 24 m; route offset +28 m; placement radius 4 m. Resolved center (3.922, -33.622, -517.600) m; record seed 1544480482218982.
motif/platform-01-v1: rounded-box plinth, half extents (3.2, 2.8, 0.75) m; route offset -35 m; placement radius 4 m. Resolved center (-37.031, 9.940, -528.850) m; record seed 2227196533846249.

Both use a 0.55 m geometric rounding radius and 1.6 m cubic smooth-union width (2√2 × 0.55 = 1.556 m). The monolith uses a rounded capped-cylinder SDF; the plinth uses a rounded-box SDF. Their fills compose into the flat field with smooth min. Resolved AABBs include the smooth-union padding (W/6 = 0.267 m):

Monolith: [2.255, 5.588] × [-35.289, -31.956] × [-529.866, -505.333] m.
Platform: [-40.498, -33.564] × [6.873, 13.007] × [-529.866, -527.833] m.

Cylinder interval bounds use exact radial minima/maxima over each XY box plus the vertical interval; platform bounds use its rounded-box intervals. The BVH contains these bounds and isTileShapeFree blocks motif-overlapping tiles. Brute-force checks: 8 boxes, 512 samples, zero misses; 2 all-air and 2 all-solid proofs; both false-proof controls rejected.

Reachability and surface audit

The final-field passage route passed with 33 points, 5,733 capsule samples, 0 blocked samples, 477 support probes, 0 unsupported probes, and 0 grade failures. Motif route and band keepouts passed.

Whole-surface LOD0 audit covered the monolith foot and cap and platform edges (4,706 tiles; 1,847,639 triangles; 0 degenerate). Fitted radii: foot 0.856 m, cap 0.728 m, platform 1.165 m. Each exceeds 0.5 m. Missing-ROI, sharp-fillet, and empty-mesh controls were rejected.

Timing, tiers, and determinism

Motif cold timing: first tile 0.076 s, near ring 0.144 s, whole view 0.524 s against the 1.75 s target. Final verify.py results: fast PASS, 167.9 s; medium PASS, 961.1 s; full PASS, 1,135.3 s. Full included the 30-cell check and five paired cost checks. Clang and GCC builds used FP contraction off; motif hashes matched at W1/W8/W12 for the monolith and both random cameras, including the camera at the monolith.

Trials and failed runs

9/15 trials used: seven evidence/capture attempts failed and two passed. Failures were limited to the initial medium audit missing the platform ROI, the clip-radius safety guard, camera crops that omitted the platform, an overly restrictive fillet upper bound, and one temporary capture-helper floor name error. Logs are under Saved/Linux/l56/; the final fast, medium, and full tiers passed.

Orchestrator review (Claude)

Accepted. The stamp matches the final Clang and GCC builds (5960b761…); 9 of 15 trials. The monolith reads as an intentional, cleanly rounded monument; the motif stratum runs at 0.52 s whole view. Logged for later: the overview shows a dark crescent where the large arrival shaft (the passage structure from the strate above) meets the floor. Check whether that's a real gap in the field or a render artifact; it isn't part of this round's motifs.
