The passage mouth fade multiplied the signed carve distance by zero, which turned native rock into an open surface (the reason earlier rounds stamped walk pads at mouths); it now blends between the uncarved field and the full signed carve. The FI style-0 route followed a lifted grade envelope over the crater (the "bridge"); it now runs on the rim and follows the native surface. New built-shape and crease audits with thresholds frozen before the fix (L36 and box controls fail). 24/24 passage rows, 30/30 determinism, 16/16 invariants, 18/18 interface/ring. Unreal: one recipe setter (uncompiled). Research R1 (read-only, web): ranked proposals for natural walkable mouths, floor-limited carve first.
