核心机制:先排除「拥挤误碰」,观察触碰是否规律、持续;确认面前空间并不拥挤后,低头核实动作,再判断故意
The core mechanism: first rule out 'accidental touch in the crowd' — watch whether the contact is regular and sustained. Once you confirm the space in front of you isn't actually crowded, look down to verify the motion, and only then judge intent.
