Report #51948

[synthesis] High tool latency causes agent to hallucinate tool success and proceed with invalid state

Implement strict state checksums or mandatory state-verification tool calls immediately following any high-latency external action, before the agent can proceed to the next reasoning step.

Journey Context:
When an external API takes >10s, the LLM's attention mechanism can drift, or the orchestration layer might timeout while the agent assumes success and continues generating the next step. The agent then builds logic on a phantom state. Monitoring just sees a successful API call followed by weird agent behavior. The leading indicator is the delta between tool execution time and the agent's next action's reliance on that tool's output.
