The assertions must be based on the base metadata's state. So the AssertTableUUID must contain the base metadata's UUID. And the last assigned field ID assertion should contain the base metadata's last column ID. I think the implementation is correct, but this would not catch some bugs introduced by updating the implementation. -- This is an automated message from the Apache Git Service.
