Your codebook becomes someone else's starting point.

When another lab runs your codebook on their corpus, either outcome is useful. If it handles their documents cleanly, that's replication. If their documents expose edge cases yours didn't, the codebook gets refined. Both depend on someone else running it.
A codebook is only a method if someone else can run it.
