Ow of course don’t worry I didn’t fill in the reliefs.
That photo is the rear side of the fork (photo taken from that side as that was actually the damaged hole/too low). On the front side I did file to keep the original shape of the fork in tact,
i did use metal filler rather than brazing in the end, down to not having access to my usual friends dads workshop. This was a diy job at my parents.
not worried structurally personally. And pretty happy as it’s totally unnoticeable now
