The י of the word biveisecha, looks like it is a triangle touching a drum stick (excuse me for lack of a better word). The Mishnas Sofrim expains that a י needs to have shiur gufa milo kolmos. Certainly this does not have it before it breaks down. On the other hand the klal, Ain Shiur LOivi osios, perhaps could apply over here.
What is the rule in this case?
