If you're referring to this part:
> This does mean that concurrent changes can conflict, but Claude can typically fix these conflicts faster than humans can even identify them.
We never allow textual conflicts, but semantic conflicts (for example, if someone adds changes the logic of a function and cleans up all affected callsites concurrently with a new call being added) are an unavoidable fact of very large repos unless you completely serialize merging with running extensive validation at the proposed batch tip, which isn't practical at a certain commit rate.
As for cross-repo changes, not exactly, but there are ways we could allow such a thing if we wanted. We're thinking about it.
