[architecture] What memory pattern should I use for cross-session persistence?

Persist agent state as checkpoints keyed by thread\_id, not as a flat message log, and resume execution from the last completed super-step.

Journey Context:
Storing raw chat transcripts and replaying them is fragile because intermediate reasoning, tool outputs, and side effects are lost or re-executed. LangGraph's checkpointer saves graph state at super-step boundaries, which enables exact resume, time-travel debugging, and human-in-the-loop. For cross-session agent memory, persistence is a state-machine problem, not a message-log problem; the right abstraction is a checkpointed graph state.
