    "The underspecified multiple-vehicle interaction is instantiated as exactly four modest passenger cars moving in parallel, followed by eleven adults. Vehicle occupants are enclosed, non-critical occupants rather than additional marching actors.",
    "Eastward motion includes a northward component of 0.08 m per metre of eastward travel to follow the supplied road geometry. The initial interaction is within x=31..46; continued motion extends beyond the usual work area while remaining on the map.",
    "Full-road occupation means no vehicle-width passage through or around the following crowd, not overlapping people or physically covering every centimetre of pavement.",
    "Ego is implicit: x=0, y=0 and speed 6 m/s at -7 seconds, smooth deceleration at 1.5 m/s squared to x=12 at -3 seconds, then a stationary hold.",
    "All support roots use z=0 above their mapped surfaces. The finite timeline ends with the procession still moving; no turnaround, removal or repeated cycle is proposed.",
    "Any later Image 2.5 edit must use original Image 3 only after human approval, taking position and posture guidance from this rehearsal. Background parked-vehicle positions are not supplied in 3D and require overlap review."
