+## Usage Notes
+- Complete one card per source for full verification
+- Batch summary should be produced after all cards are complete
+- Minimum spot-check: 20% of sources get full card assessment
+- All Grade D/F sources require documented justification
+- Any predatory journal flag requires full verification
