CCTV camera footage. Fixed angle. 9:16 vertical crop. 15 seconds. Apartment building ground floor corridor. Plain walls. Tile floor. Automatic heavy glass entry door (spring-loaded). Flat CCTV lighting. Slight blur. Timestamp top corner. No sound. No camera movement. A small child (2–3 years old) is walking slowly toward the door from inside. A large dog is walking right behind the child, very close — normal following behavior. The child pushes the door slightly and steps forward. The door begins to swing back automatically (slow but heavy). The child stops suddenly to look down at something on the floor — now standing directly in the door’s return path. The dog keeps moving forward and: its body blocks the door the door hits the dog’s side, not the child Because the dog is bigger and heavier, the door loses momentum and slows. The child steps forward safely and clears the doorway. The dog then steps through and the door closes behind them. Final frame: Child walking ahead, safe Dog following normally Door closed No jumping. No pulling. No timing miracle. Just mass + position + normal movement.
