Output Voltage Feedback Circuit interpretation

I see reference design of Texas Instruments PMP40766 Universal input, 500-W CC/CV e-Bike charger reference design , In the design I don't understand the reason of diodes at the feedback circuit I share below from the Schematic — PMP40766 . And the 1uF capacitors at between shunt resistors. Can anyone explain the circuit. I guess the purpose of complete network is compensation for get the desired output feedback. But diodes? Thanks.
