Report #87454

[frontier] Agent crashes during long-running tasks lose all intermediate progress and require full restart

Wrap agent steps in Temporal.io workflows with durable execution, checkpointing after each LLM call with automatic retry and timeout handling

Journey Context:
Current agent frameworks run in-memory; if the process dies \(OOM, spot instance termination\), the entire agent trajectory is lost. For 2025 production deployments, the pattern is to use Temporal.io \(or similar durable execution engines\) where each agent step is a Workflow Activity. The workflow state is automatically persisted after each Activity completion, enabling 'pause and resume' across days and crash recovery. Retry policies are declarative \(exponential backoff for rate limits, immediate retry for context window errors\). This enables 'sleeping' agents that wait for human approval or external events for weeks without holding memory. Alternative: LangGraph's built-in persistence is single-process and doesn't survive process death.
