The single thing that stood out to me was the size of the traces... Protective devices usually have shorter and Much wider traces, those appear to be 8 to 10 mil traces or inductors in series with the protection. I really don't know what the parts actually are I just tried to figure out "IF" those were protection devices than it would be a mistake to use small "wires" (PCB Traces) to provide the interconnection. These are part of "Basic" design rules for PCB layout and my reasoning in "reverse" engineering the subject.
