Persistence Layer
An architectural layer in AI Agent systems responsible for fully storing interaction state. It supports cross-session memory management and human-in-the-loop mechanisms, analogous to state management solutions in front-end development. It serves as the foundation for reliable operation of production-grade Agent systems.

LangGraph adds a persistence layer by default, capable of storing the entire AI interaction process completely, including two features: memory management (Memory) and human-in-the-loop.
Human-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.
