Extraction failures persist under dense retrieval: on a matched per-hop criterion they are more numerous with Contriever than BM25 on MuSiQue, and most BM25 extraction failures shared by both retrievers remain extraction failures.

The complete result group stays with its claim. Assessed rows come first; their judgments do not replace the whole-claim conclusion. Expand a row for conditions, sources, and evidence history.

Each row is a measurement with its reported value, latest available observation, and cumulative evidence state.
