You’ve listed four AI-generated bullet points of “changes” for a +1 line diff, none of which are what you actually changed, so how am I supposed to trust anything else you’ve supposedly written?

I sincerely apologize if my actions came across as inappropriate. Since this was my first experience contributing to open source, I was still trying to understand how the process works and had to rely on external sources for guidance. If my approach seemed rude in any way, I kindly ask for your understanding and
forgiveness, sir.
