Understanding Code Management in Cursor

I am new to cursor, and trying to understand code management in the default system. I haven’t installed git extensions for windows.

I have been using the built in roll back capability within the composer conversation, but yesterday composer froze in the middle of a code change and screwed it. Because composer remained frozen, I was unable to roll it back using that feature.

So can you tell if its possible to achieve a roll back now? or if there are any versions stored anywhere so I could manually rebuild?

Thanks in advance.
