UnverifiedLangGraph通过StateGraph维护不可变的状态对象，每次状态变更生成新的状态版本而非原地修改76% similarUnverifiedLangGraph的状态合并机制在理论上是一个幺半群（Monoid）操作，通过Reducer合并增量更新以保证并发状态一致性72% similarUnverifiedLangGraph combines graph state machines with LLM reasoning, where nodes are tool or LLM calls and edges are conditional transition logic, with a persistence layer (Checkpoint) ensuring that processes can be interrupted and resumed.71% similarUnverifiedLangGraph 的边分为普通边（无条件跳转）和条件边（根据当前状态值动态决定路由目标），条件边是实现分支逻辑的核心机制68% similarUnverifiedLangGraph通过TypedDict或Pydantic模型定义状态Schema，并支持Reducer函数规定状态在节点间合并更新，例如消息列表用operator.add追加策略68% similar
