Report #66247

[frontier] My agent loses all progress when the server crashes during a long-running task because state is stored in memory.

Use a checkpointing system \(like LangGraph's persistence layer\) to serialize the agent's graph state \(messages, channel values\) to a database after each step, enabling resumption from exact point of failure.

Journey Context:
Serverless functions kill containers after timeouts; long-running agents need 'hibernation'. Checkpointing treats agent execution as a database transaction log, persisting state to Postgres/Redis after every node in the graph. This enables human-in-the-loop approval steps that can pause for days and crash recovery without losing context. Essential for reliable autonomous agents that run 24/7.
