…nce move past a catchup request. When a server restarts and does a stream catchup where the snapshot from the leader is for messages it no longer has, we would create a sequence mismatch reset on the follower. Also on a catchup if the stream state has moved past the updated request range from a follower, meaning first for the new state is past the last of the request, extend and continue catchup.

When a server restarts and does a stream catchup where the snapshot from

Also on a catchup if the stream state has moved past the updated request
range from a follower, meaning first for the new state is past the last
of the request, extend and continue catchup.
