# Orphan and Gap Audit

- unified knowledge nodes: 590
- cross-reference edges: 2513
- evidence artifacts indexed: 130
- structural historical-claim orphans: 0
- structural current-finding orphans: 0
- evidence artifacts without a literal path reference before indexing: 14
- remaining evidence orphans after complete artifact indexing: 0
- historical-only retained claims: 462
- current-only findings: 63

A historical-only claim is not an orphan: it remains connected to a source
item, reviewed status, retention action, and target destination. A current-only
finding is likewise not an orphan when it has evidence and a canonical target.
The distinction prevents artificial links from being added merely to make the
graph denser.
