Are these Test points or Jumpers or Anything else ?

I am studying max77542ev kit pdf. In which I am not getting some of the footprints. In BOM, It suggests that In1 - In 4 etc. are buss bar (20 gauge copper wire which looks sorted in pcb board image). In PCB layout some of that are directly connected to polygon (see in pcb layout image right bottom layer in this case). What are this ? It neither seems like test points neither jumper. What is the purpose of this? Why silk screen in that area is directly exposed to copper pads?

Test or connection points. Shaped so you can hook clips or scope probes to them easily. It is an evaluation board so it would be expected that testing would be done with it.

Hey Brian, Thanks for reply.
Here as per BOM, IN2S is also a test point. These both test points are connected to same net. Probably they require two probe for testing purpose. Right? But why they routed long IN2S track separately while we can directly route it vertically from IN2 pad (or from polygon)?
They did the same thing for IN1-IN1S, IN3-IN3S AND IN4-IN4S.
