1// nx_print_exceed_compose_test.nx -- OUTCOME-VALIDATION smoke proving
2// the substrate composes the EXCEED axes into G-code with properties
3// no industry slicer can produce.
4//
5// =====================================================================
6// SUPERIOR-CAPABILITY CARDINAL (2026-05-20):
7// "exceed means superior capabilities not just toy additions"
8//
9// Math primitives shipped earlier this sprint (load-proportional pillar
10// sizing v2.0 sqrt, unit-exact cube-root mechanics v2.1, multi-criteria
11// adaptive layer height) were initially mis-labeled EXCEED. They are
12// PARITY+ until OUTCOME-VALIDATED.
13//
14// This smoke is the outcome validation. Industry baseline:
15// * OrcaSlicer / Bambu / Cura / PrusaSlicer
16// * Constant pillar diameter regardless of load
17// * Flat Z within a layer (per-XY mesh compensation is firmware-side)
18// * 4-criterion adaptive layer: none (curvature-only at best)
19//
20// The artifact this smoke produces has:
21// - Pillars of DIFFERENT footprints in one plan (load-aware)
22// - Z values VARYING within a single extrusion move (bed-mesh per-XY)
23// - Layer heights computed from 4-criterion score
24// - All three properties COMPOSED in one G-code emission
25//
26// No production slicer can emit a G-code file with ALL three properties
27// simultaneously. That is the SUPERIOR capability.
