Report #75769

[frontier] Stateful agent graphs lose track between serverless API requests or crashes

Configure SqliteSaver or PostgresSaver in LangGraph with unique thread\_id to persist graph state \(channels\) across serverless invocations, enabling resumption mid-workflow

Journey Context:
Serverless functions are stateless; LangGraph's checkpointer serializes the entire agent graph state \(including loop counters and message history\) to a database, allowing the graph to resume from the exact step after a crash or cold start.
