Sorry for the nitpick but we actually don't want to mark it as cancelled if there is an issue. Otherwise that's an easy way for people to mark proposals as cancelled which is a real outcome.
Instead we want to fail. I probably need to add some tools to modify some bad votes or something like this but first I want to see if that's really needed and how people try to abuse the system.
I am also not sure if that can even happen if we get to that point in the code.

Strengthens the governance contract by addressing unsafe patterns, clarifying rules, and adding protective checks. It improves security, maintainability, and auditability.
