Report #69323

[synthesis] RAG agent successfully executes actions based on outdated retrieved information

Inject a temporal confidence check: force the agent to extract and output the last\_updated or version timestamp from the retrieved document before executing the action. If the timestamp is older than a policy threshold, halt execution.

Journey Context:
Vector databases return documents based on semantic similarity, which heavily favors legacy, highly-cited documents. The agent successfully parses the old API format and makes a call that returns a 200 OK \(because the old API is still supported but deprecated\), but the business logic is wrong. Standard error monitoring sees success; temporal extraction catches the silent drift by forcing the LLM to ground its actions in time.
