- Verification
- Performs an exact-quote check and, when enabled, a model-based faithfulness check.
- Evaluation
- Includes SciFact-based evaluation and CI regression checks. The benchmark notes also document cases where BM25 outperformed hybrid retrieval.
- Operations
- Includes health endpoints, audit trails, Prometheus metrics, and an example Grafana dashboard.
