One thing that comes to mind is that an AI might see the code and say "Yeah, this should compile / no obvious runtime errors", but the AI doesn't have the context to know your teams coding standards (every team has different standards). That said, there are ways to feed that context to the AI, but still risk hallucinations, etc.
Presidents shouldn't have the right to outright pardon people. It should have to go through some sort of body beforehand and be voted on like everything else.
I think if this is targeted at kids, you may want an email signup. I.E. someone just getting started with coding probably doesn't have a Github. That said, I love the initiative to help kids/people learn to code!
