What you need to know
- 01
The approach preserves source identities instead of pooling all evidence together.
- 02
It checks support and attribution after an agent produces an answer.
- 03
The authors describe claim-level verdicts and a repair-and-recheck process.
Why it matters
A correct statement with the wrong citation can mislead a reader. Source-level checking matters when an agent combines records, search results, and documents.
