Report #5702

[architecture] Agent loses its entire execution state and progress if the process crashes or is interrupted mid-task

Adopt an event-sourcing architecture where the agent's actions and tool outputs are appended to an immutable log, allowing state reconstruction by replaying events or loading periodic snapshots.

Journey Context:
Standard chat APIs are stateless, and agent state is often held in volatile memory arrays. If an agent executing a 10-step plan fails at step 8, it has to start over. Event sourcing \(append-only log of actions/observations\) means state is never lost. To avoid the cost of replaying thousands of events from scratch, implement periodic checkpointing \(snapshotting the current context/state\). Tradeoff: higher engineering complexity and storage overhead, but essential for robust, long-running autonomous agents.
