多智能体经典架构方案，所有Agent读写同一份共享状态，通过竞争监听机制决定任务处理权，在LLM场景下以共享内存或向量数据库形式复现
该框架中Agent之间不直接通信，只通过读写文件来传递信息，采用类似黑板系统（Blackboard System）的架构模式
The blackboard system concept originated in the HEARSAY-II speech recognition system of the 1970s (1971–1976), and awman's workflow context directory is an implementation of a blackboard system.
