1// nx_cad_exceed.nx -- MEASURED head-to-head census for Nishi CAD vs incumbent CAD
2// (FreeCAD / AutoCAD / Fusion 360 / Siemens NX).  Per the doctrine [no-wave-
3// measured-exceed + author-by-organ]: grades are COMPUTED by running real checks,
4// never self-scored, and the census is HONEST -- it records the axes where we are
5// BEHIND, not just where we lead.  Three superiority axes are proven IN-PROCESS
6// here and re-used by the live page so the claims on nishifamily.com/cad are live
7// measurements, not typed numbers:
8//   (1) DETERMINISM   -- two independent pipeline runs are byte-identical (float
9//                        CAD kernels are not bit-reproducible across runs/machines)
10//   (2) WATERTIGHT    -- curved geometry slices into CLOSED contours by construction
11//   (3) INTEGRATED    -- one sovereign tool goes sketch -> solid -> slice -> G-code
12//                        with zero third-party binaries in the path
13// license_tier: ORIGINAL
