[research] Production traces contain failures but no systematic way to turn them into eval coverage

Run online evaluations on a sampled or filtered subset of production traces, surface failing traces into an annotation queue, promote validated failures into offline eval datasets, and run them in CI before the next deploy. Close the loop: production incident becomes regression test.

Journey Context:
Offline evals give repeatability but miss real-world distributions; production monitoring sees real traffic but is reactive. The flywheel combines both: online scoring detects drift and new topics, humans review the high-signal traces, and curated cases become future regression coverage. This requires trace-to-dataset infrastructure and versioning of prompts, models, and tool schemas so regressions can be tied to specific changes.
