为何这一结构有效
- Per-claim labelling stops one wrong number from discrediting the whole passage.
- Asking for the confirming evidence turns the output into a to-do list.
常见失败与修复
The checker asserts SUPPORTED without a source.
修复：Require a citation for any SUPPORTED label, or downgrade to NEEDS-SOURCE.
已知局限
- The model may not know recent facts; enable grounding where possible.
