Report #100251

[architecture] The agent forgets everything after a restart because state only lives in RAM.

Use two persistence layers: a checkpointer for short-term, thread-scoped state keyed by thread\_id, and a namespaced store for durable cross-thread facts. Never store user preferences only in MessagesState.

Journey Context:
LangGraph separates short-term checkpoints from long-term stores. Many agents conflate the two and either lose memories on restart or leak one user's history into another. Checkpoints give continuity and time-travel; stores give cross-session personalization when scoped by user/org/namespace.
