+#### Reconciling People Data
+
+The reconciliation tool compares member/alumni data across `people.xlsx` (source of truth), `JRM_CV.tex`, and the lab-manual's `lab_manual.tex`:
+
+```bash
+cd scripts
+
+# Report discrepancies without making changes
+python reconcile_people.py --dry-run
+
+# Apply auto-fixes (people.xlsx entries missing from other sources)
+python reconcile_people.py
+```
+
+The tool uses fuzzy name matching to catch spelling variations and nicknames. Discrepancies are categorized as:
+- **Auto-resolved**: People in people.xlsx missing from CV or lab-manual (auto-added)
+- **Flagged for review**: People in other sources missing from people.xlsx (requires manual review)
+
+**Requires**: Lab-manual submodule initialized (`git submodule update --init`)
+
 #### Adding Alumni (Manual)
 
 1. Open `data/people.xlsx`
