After escalate_to_human transfers a case, the receiving agent has no customer context and must re-interrogate the customer from scratch. Which change to the escalation handoff most directly solves this problem?

1. ALog the full conversation transcript to a database before calling escalate_to_human so human agents can retrieve it manually.
2. BInclude a structured payload with verified customer ID, issue root cause, and prior steps attempted when invoking escalate_to_human.
3. CExtend the session timeout window so the human agent inherits the same active context as the original agent.
4. DPrompt the agent to summarize the case in its final message before handing off, relying on the human agent to read it.
