[frontier] How to prevent long-running agent workflows from losing state on container restarts

Implement agent workflows in Temporal.io \(or similar durable execution platform\) instead of stateless serverless functions; model tool calls as Activities with idempotency keys.

Journey Context:
Current agent frameworks \(LangChain, LlamaIndex\) default to stateless request/response cycles. When a container restarts mid-task, the agent loses all context. This is catastrophic for multi-step research or coding agents that run for minutes/hours. Temporal.io \(and alternatives like Inngest, Hatchet\) provides 'durable execution' - the code appears linear but is checkpointed to event history. Key pattern: separate deterministic 'Workflow' code \(LLM planning\) from non-deterministic 'Activities' \(tool calls\). Common pitfall: passing LLM responses directly between workflows; instead, hydrate state from Temporal's search attributes. Alternative of using Redis for state requires manual checkpointing and retry logic. This pattern is becoming standard for 'agent-as-a-service' platforms in 2025.
