- [ ] Set up authentication and user roles

### Data Migration

- [ ] Export documents from current system
- [ ] Transform documents to Fess format
- [ ] Validate NDJSON format
- [ ] Import documents via Admin UI or API
- [ ] Verify document count after import
- [ ] Test search queries on migrated data
- [ ] Configure document boost/relevance (if needed)
