Failed kamikaze attempt. Need help.

DIODE VALUES

red 0.85

blue 0.753

yellow 0.792

pink 0.924

Felt like it happened in an instant. Obviously grinded a bit too deep. I have a video from my microscope . Do I just run a wire from blue to purple and will that fix it or did I go even deeper?

everything else measures ground btw

Measure whether the red 2 ends are conductive, and measure whether the blue and purple ends are conductive. If they are conductive, then everything is fine. If they are disconnected, you need to connect them.
No more polishing needed.

ordered some 0.05mm enameled copper wire. tried all day yeserday to fix it with 38awg insulated wire and realized I was just wasting my time. Would you recommend grinding more to expose more of the trace at the top? Realized I grinded a bit too far to the left there should be way more trace left for both of them.

Fixed.

No need to polish again, 0.05mm enameled copper wire can be directly welded.
