[synthesis] Agent eval scores remain perfect while production success rate silently drops

Continuously mine production failures to dynamically update the eval suite, and weight eval scores by the real-time distribution of incoming user prompt intents.

Journey Context:
Teams build static eval suites \(e.g., 100 coding tasks\). The agent aces them. In production, user prompt distribution shifts \(e.g., a new library is released, and users start asking for migrations\). The agent fails these new types of tasks, but the CI/CD pipeline still reports 100% on the static evals. The silent degradation is in the relevance of the eval suite itself. The leading indicator is a growing divergence between the semantic clusters of eval inputs and production inputs. This synthesizes MLOps data drift monitoring with LLM evaluation practices.
