about

nx_csg_test.nx -- KAT gate for SDF + marching-tetrahedra CSG booleans. Proves: (a) the difference actually REMOVES material (fewer inside samples than the box alone), (b) the result is a valid mesh with the box's extent, (c) it slices WATERTIGHT and a mid cut shows >=2 closed loops (outer wall + the hole = the topological signature of a through-hole), (d) the CSG solid prints (real G-code). This is the CSG-booleans rung moving from BEHIND toward parity. expect_exit: 0.
