Expreiance with some exploits

I have been trying to do an exploit, I searched the internet looked at older documentation and even asked AI without use the whole internet was agreeing it is impossible even AI was hellucinating at somtimes, I kept reversing structures debugging kernel and user softwares for any sign of clue, in the end I managed to pull it off after 2 months of consistent work, only to find a repo that has like one source file and one header file in cpp in github that perfectly does the exact thing I was looking for, I didn't even commit it to my repo the whole thing is embarresing
