nx_adaptive_layer_test.nx -- prove multi-criteria adaptive layer height EXCEEDS Cura/Orca/Prusa's curvature-only heuristic. Closed-form invariants: (a) Zero score (no criterion fires) -> max layer height (b) Max score (all criteria saturated) -> min layer height (c) Single criterion at max + others zero -> partial reduction (d) Each criterion has DISTINCT impact magnitude (weighted, not equal): curvature > load > bridge > overhang (e) Out-of-range inputs clamp safely (f) Monotonicity: more curvature -> finer layer (smaller height); more load -> finer layer; bridge present -> finer; overhang proximity -> finer (g) EXCEED MEASUREMENT: 4-criterion (all max) layer < 1-criterion curvature-only (Cura-equivalent: load=bridge=overhang=0). Industry's single-criterion solver under-resolves regions where curvature is low BUT load/bridge/overhang is high. (h) Backwards compat: when load=bridge=overhang_prox=0, the result is the SAME as a hypothetical single-criterion solver weighted to (curvature_weight / total) * span expect_exit: 0 license_tier: ORIGINAL
