Report #91408

[synthesis] Agent uses expired or stale external state after long LLM reasoning steps

Implement time-bounding for tool outputs. Inject the timestamp of the observation into the prompt and instruct the agent to re-fetch if the current time exceeds a delta.

Journey Context:
Agents often read a file or API, then spend 30-60 seconds reasoning or calling other tools. If the underlying data changes during that reasoning window, the agent's subsequent actions are based on stale data. No error is thrown because the API calls are valid. This is a silent degradation specific to agents operating in dynamic environments \(like coding agents editing files\). The fix requires making the agent temporally aware, a dimension standard monitoring ignores.
