UnverifiedHuman-in-the-loop allows pausing at specific nodes in the Agent's execution flow to await human review or intervention before continuing, and relies on the persistence layer to save the complete state at the time of the pause in order to resume execution from the breakpoint.80% similarVerifiedLangGraph has built-in checkpointing support for state persistence, allowing an Agent to resume from a breakpoint after interruption.79% similarVerifiedLangGraph通过内置的Checkpointer机制支持将图执行的每一步状态快照持久化，实现断点续跑能力79% similarVerifiedLangGraph abstracts an Agent's execution process into a persistable, replayable state graph, enabling complex multi-step tasks to resume from a breakpoint after interruption.78% similar
