    "body_text": "JitterVLA isolates controller effects by replaying the same commands and arrival delays. Interpolation reduced modeled jerk at a tracking cost; exploratory physical-robot tests showed smaller measured gains. The benchmark supports screening motion quality before human-centered studies, rather than declaring a controller safe around people.",
