  "finding": "The readable draft explains the family relationships through shared operations, conserved quantities and explicit source junctions. The completed journal retains a reassessment after every action. Forty-eight analytical steps received independent review; the final two consolidate review and synthesis. The next source-family test remains unexecuted.",
