about

nx_footplant_gate.nx -- ★Q5 FOOT PLANTING (the motion-realism audit named it: "feet float mid-stride, no ground contact"). The ground-contact solve forward-FKs each foot's sole through its (hip,knee) chain and drops the being onto its stance foot. T1 the FAULT measured (plant off, walk pose: the lowest sole floats). T2 the SOLVE closes it (all four poses: lowest sole back at rest ground +-6). T3 causal SDF probes (ground-band occupancy flips). T4 no regression at stand (offset exactly 0) + determinism. T5 evidence render (walk pose, off | on). license_tier: ORIGINAL expect_exit: 0
