Here’s how Harvard (and the local rag known as the Boston Globe) explain it away: https://ori.hhs.gov/definition-research-misconduct
Clear plagiarism by any academic measure, but someone who long before reaching the PhD stage would be well aware of definition thereof.

So they are simply allowing her to make “corrections:.
I’m old enough to remember when the standard at pretty much any undergraduate college in the country was mandatory expulsion for any plagiarized submission in any course.
