### 2. 100% Externalized Configuration

#### ✅ Excel-Based Configuration
No code changes needed - all behavior defined in Excel:

| Configuration Aspect | Location | Flexibility |
|---|---|---|
| **Field Extraction** | `Inclusions_Mapping` sheet | Define which fields to extract, from which sources |
| **Organization Fields** | `Organizations_Mapping` sheet | Define which org fields to export |
| **Excel Export** | `Excel_Workbooks` + `Excel_Sheets` sheets | Define workbooks, templates, sheets, transformations |
| **Quality Rules** | `Regression_Check` sheet | Define expected data changes & validation rules |
| **Organization Mapping** | `eb_org_center_mapping.xlsx` | Map organization names to center identifiers |

#### ✅ Supported Configuration Types
- **Field sources:** Questionnaire (by ID/Name/Category), Record, Inclusion, Request, Calculated
- **Value transformations:** Labels, templates, boolean conversion, list joining
- **Field conditions:** Optional conditional execution (N/A if condition false)
- **Custom functions:** Business logic without code modification
- **Filters:** AND-condition filtering with nested field support
- **Sorting:** Multi-key sorting with datetime parsing
- **Value replacement:** Type-strict mapping (boolean, enum, status codes)

---

### 3. High-Performance Multithreading

#### ✅ Parallel Processing Architecture
- **Organization processing:** Up to 20 concurrent workers
- **Patient processing:** Nested async pool (40 workers) for lab/questionnaire fetches
- **Configurable thread count:** User selects 1-20 workers
- **Non-blocking I/O:** Async lab fetches during main processing

#### ✅ Performance Optimizations
- **Questionnaire batching:** Single API call per patient instead of N calls (4-5x improvement)

- **Nested parallelization:** Outer pool for orgs, inner pool for async tasks
- **Progress tracking:** Real-time multi-level progress bars with thread-safe updates

#### ✅ Typical Performance (Full Dataset)
```
Data Collection: 2-4 minutes (1,200+ patients, 15+ orgs)
Quality Checks: 10-15 seconds
Excel Export: 5-15 seconds
─────────────────────────────
TOTAL: 2.5-5 minutes
```
