ok vias i get that

for chips the dot seems to align with the square layout hole, any special significance of the square holes (pos, neg?)
U11 (photorelay optocoupler) has two stamped dots (small and large) and one printed dot. The big stamped dot and the printed dot are in the same corner. I'll assume that's the dotted corner that goes in square layout hole (closest to silk-screened notch on pcb).

Fox Crystal goes whichever way (no polarity?)?
