Stopped by the owner (he wanted his PC back to play) after most acceptance was in. Measured with the owner's assets: the shelf across rooms came from the tunnel core reasserting solid below its floor inside room volumes, plus the landing-floor post. Room ownership now suppresses the tunnel bottom in the generic tunnel SDF, the core evaluator and both native fallbacks: tunnel-attributed solid inside rooms 469 -> 0, and a matched-camera re-render shows the slab gone. Trimmed mouth endpoints now take their height from the room's own vertical zero crossing (join offsets -2.08/+0.40 -> -1.13/-0.71 voxels). Mouth surface periodic amplitude 1.49 cm floor / 0 cm wall (degree-six trend removal; raw local-median audit 6.19 cm kept). Canonical walk Connected, 42,870 fit / 17,413 walk-reachable (was 41,184 / 13,879); export 141,054 triangles, geometry hash 86A99075. Launches use an isolated engine saved/config directory so the owner's editor settings are not rewritten.
NOT DONE: the -voxel.CrtFma3=0 export comparison, TilePostReachProof / DetSinCos / strate crossing, the perf pair vs the experimental tip, the EditorSettings.ini diff. Unvalidated in game.
