The remove-one ablation, re-confirmed on the current build, puts the cave warp at 11.0% static / 11.8% moving of worker time: three independent Perlin3D calls per sample. VoxelNoise::Perlin3D_x3 evaluates the three warp channels together through the existing SIMD evaluator (Codex; reviewed by me). It is wired into the generator, op-stack, classifier and room/player-fit unwarp paths. Exact: the field is byte-identical. 0/841 tiles changed, 0 triangle delta, 0 voxels of maximum surface displacement; canonical export 07C14005 / b3e5f4c3..9b377; capability 20,830 / 10,909; strate-crossing and sealed-proof tests pass. The seam test (VoxelForgeMazeSeamTest, extended) has 48 neighbouring-tile and 24 cross-LOD comparisons, 0 mismatches. Before/after renders from a camera aimed at the real arrival tunnel are byte-identical. Cross-machine determinism: Perlin3D_x3 adds no new intrinsics, no AVX, no FMA and no runtime CPU dispatch. It reuses the evaluator behind the compile-time gate `#if PLATFORM_ENABLE_VECTORINTRINSICS && PLATFORM_CPU_X86_FAMILY`, so every x64 machine runs the same instruction path; its output matches the scalar path bit for bit. Final DEFAULT build vs the committed-tip DLL (two interleaved runs each): static worker 30.83 -> 29.47 s (-4.4%) LOD0 generation p50/p95 56.3/99.3 -> 53.3/95.3 ms moving worker 67.28 -> 64.56 s (-4.0%) LOD0 generation p50/p95 55.9/99.0 -> 53.4/96.4 ms Ledger: every launch passed; two harness false negatives (the seam test on the game-only validator, and a trace ended by intentional forced termination) were rerun. No crash folders. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TaFdXhTdYMkW1xrV6ApT6Y
