I am confused that the scratch goes up to the lip of the liner. So it probably wasn’t anything related to piston rings. Their movement stops about 1 cm from the top and about 4-5 cm from the bottom of the liner. I guess that something must have been stuck between the top of the piston itself and the liner. Thats the bottom of the liner right? The silver part is actually the not worn part where the piston and its rings dont even come...
I have seen similar damage caused by piston removal as well. If you are not careful and slide up the piston-conrod assembly off the crank, the conrod can scratch the liner going up. Seems like this on the first look.
