[research] How do I evaluate quality on live agent traffic without evaluating every request?

Run the same scorers used in CI as online evaluators on a sampled subset of production traces \(e.g., 5-10%\). Route low-scoring traces to annotation queues and promote failing patterns to offline regression datasets automatically. Keep scorer definitions identical across dev and production to avoid drift between 'what we test' and 'what we monitor.'

Journey Context:
Offline evals cannot cover the long tail of real inputs. Observability platforms support online evaluators that score live traces with the same code used in CI. Sampling controls cost; auto-promotion closes the loop. The anti-pattern is maintaining separate eval logic in dev and prod, which slowly diverges and makes production alerts unactionable.
