nx_supports_physics_test.nx

nx_supports_physics_test.nx -- proves bits-up physics-aware pillar sizing produces DIFFERENT pillar dimensions for DIFFERENT loads within the same plan. Industry baseline (Orca/Bambu/Cura/Prusa) cannot do this -- they emit identical pillars regardless of load. Closed-form invariants: (a) plan_add_pillar_physics with LIGHT load on PLA -> MIN footprint (matches industry baseline at the light end) (b) plan_add_pillar_physics with HEAVY load on PLA -> footprint > MIN (industry would underbuild here) (c) Two pillars in same plan with different loads -> different per-pillar footprints (industry: identical regardless) (d) Same load, stiffer material (PEEK) -> smaller footprint than PLA (industry: identical footprint regardless of material) (e) Emit produces a square that scales with per-pillar footprint (verify by ensuring HEAVY pillar emits a bigger square than a NEAR-BY LIGHT pillar in the same emit pass) (f) Merge policy: heavier load at same XY EXTENDS existing footprint (never shrinks) expect_exit: 0 license_tier: ORIGINAL
