+        Gives an answered question a different answer by forking its task, as forkSnapshot does, at the snapshot taken
+        just before the original answer was handed to the agent. The new task gets a copy of the question, already
+        answered with this response, and its agent gets the answer as its first message. The original task is untouched.
+        Refused for a question that isn't answered, an answer delivered without a snapshot, and anything forkSnapshot refuses.
