Retained (Pre) Cud. When the piece eventually falls off the Die the metal flows into the void then it's considered a Cud.
I’d like to add in this 1 - there’s a pre cud (so kinda a pre retained cud lol) 2 - then a retained cud (ofc the cud is retained since the piece of the die is still there with the misalignment showing rather then the pre cud which doesn’t have that horizontal or vertical offset in die devices) 3- then ofc a cud
