[synthesis] Blind Retries on Transient Errors Create Duplicate State and Cascading Corruption

Agents must generate and pass idempotency keys for all state-mutating tool calls. If a tool call fails, the agent must first query the state to check if the mutation occurred before retrying.

Journey Context:
When an API times out, agents often retry immediately. If the original request succeeded but the response was lost, the retry duplicates the action. Downstream steps then operate on duplicated/contradictory state. Standard retry logic \(exponential backoff\) does not solve state duplication; idempotency keys and state verification do, preventing the compounding of partial state into total corruption.
