> that's the basics of how you handle stuff like this

Anecdotal but not in my experience. The professor can inform students, collect evidence, etc without detailing each scenario in the syllabus.

Every CS class I’ve been a TA for had the same generic university provided statement on cheating.

The professors did not want to spend time thinking about or dealing with people cheating.

Every time MOSS flagged assignments they basically sat with me and the student and said “You are likely cheating. Please don’t do it again.”. No one ever admitted to cheating and no one ever got flagged twice.
