Report #54083

[architecture] Agent losing its operational state and context when a session ends or times out

Serialize the agent's state machine \(current step, variables, and a summary of the working memory\) into a persistent datastore at every major state transition, and reconstruct the context window from this serialized state plus long-term memory upon session resumption.

Journey Context:
Developers often rely on the LLM's context window to hold the agent's entire state, meaning a timeout or crash resets the agent to zero. While long-term memory \(vector DB\) stores facts, it does not store the agent's operational intent \(e.g., 'I am on step 3 of the deployment pipeline'\). You need a durable state checkpoint \(like a database row or a checkpointer\) that saves the control flow and a condensed summary of the working context. When resuming, you rebuild the context window from the checkpoint summary plus any newly retrieved long-term memories, rather than trying to replay the entire history.
