nx_slice_bridge_gate.nx

nx_slice_bridge_gate.nx -- GATE: R1-FULL. The slicer's NxPolygon type drives the multi-material emitter. T1 bridge Q14->mm correct, T2 a sliced SQUARE prints in concrete (bridged verts present, cold), T3 a sliced HEXAGON prints in filament (off-axis vert, hot), T4 never-brick both, T5 the JOIN (real NxPolygon -> any material G-code). The production slice pipeline (nx_slice_plane->nx_slice_contour) emits exactly this NxPolygon type, so any STL now reaches any material. license_tier: ORIGINAL
