[synthesis] Network Timeout Retries Cause Double Execution in Non-Idempotent APIs

Agents must generate and log an idempotency key before making a non-idempotent call. If a timeout occurs, query the system state before retrying.

Journey Context:
When an agent hits a network timeout, it cannot distinguish between a failed request and a successful request with a dropped response. Assuming 'no response = failed', it retries, causing double execution \(e.g., double charging, duplicate emails\). Combining the opacity of distributed systems with LLM lack of built-in idempotency reveals that agents blindly re-executing side-effects will inevitably cause real-world compounding failures.
