What is that scuff mark in the first image? Is that where the cut is? I see where traces have little brown spots but they still look intact. I can't see where the actual cut is.
 
Yea... the brown spots at trace are the scuff mark, they tell the copper was exposed which is CID. I'm not sure how come the PCB damaged.
