RTK Motion — 4D motion capture biomechanics. Two-subject grappling capture, 5 s (300 frames @ 60 fps, 56 joints each), delivered as DERIVED ANALYSIS inline: inter-subject engagement distance and contact time — which single-actor corpora cannot produce — plus per-joint excursion, bilateral asymmetry, motion energy, and 56-joint→43-DOF retarget fidelity. Signed raw-BVH URLs included. Full 20 s captures, NPZ trajectories and bundles via /mcp.
