Report #64393

[synthesis] Agent state diverges from external system state during high latency periods

Implement optimistic concurrency control or state versioning. Require the agent to pass a state\_version or ETag in mutation tool calls, and alert on 409 Conflict rates.

Journey Context:
When LLM inference latency spikes, the time between an agent reading a state and writing to it increases. In production, other systems or users might alter that state in the interim. The agent writes based on stale state, overwriting changes. No error is thrown if the API is idempotent or lacks version checks. The agent reports success, but data is lost. The leading indicator is a correlation between LLM latency spikes and silent data overwrites, which can only be caught by enforcing state version checks at the tool layer.
