Given a commit in googleapis/librarian, how do I know the right reference value to use here (i.e., 20250826011555-c0c043b7a0a6)?

Also, do we want to keep the two librarian repo references here - in generator_dart.yaml and sdk.yaml - in sync?

Good question ... let's see how it goes by trying to keep them in sync. If it becomes a problem we can change our minds.
