    "Playback is finite and non-looping from -7 through 40 seconds at 20 Hz, including 941 samples. The two incursions are separately authored rather than a repeated animation loop.",
    "All roots remain at z=0 relative to mapped ground. Use bounded-speed translation, stationary turns, and restrained skeletal sway without adding an unkeyed root excursion or fall.",
    "Ego approaches along y=0 from x=13 at -7 seconds, brakes from 2 m/s to rest at x=14 by -6 seconds, and stays stopped through the final frame because the obstruction persists.",
    "Exact static-obstacle footprints remain uncertain and require human inspection. Any later Image 2.5 edit must use original Image 4, with this rehearsal controlling only positions and postures after human approval."
