    "Playback is finite and non-looping from -7 to 40 s at 20 Hz. Use velocity-limited C1 interpolation and finite articulated dance phrases; small dance weight shifts are not ordinary walking.",
    "Ego is the simulator vehicle, approximately 4.6 by 1.85 m, not an additional cast actor. It stops with its center at x=12, y=0 by -3 s. Its buffered corridor is approximately |y|<=1.55, including checks against moving limbs.",
    "Ground support follows the supplied ground plane; human z values are zero offsets. Exact curb profiles, parked-vehicle depths and facade clearances remain unverified from the single photograph.",
    "The initial review time is a suggested seek point, not approval. No image generation is authorized before human review; acceptance checks are requirements, not executed test results."
