### Rhiza Impact Analysis

**Rhiza contributes approximately 3.0-3.5 points** (30-35%) to jsharpe's overall score:

- **Without Rhiza**: jsharpe would score ~6.0-6.5/10 (comparable to well-written but infrastructure-light projects)
- **With Rhiza**: jsharpe scores 9.5/10 (production-grade enterprise quality)

**Categories most impacted by Rhiza:**
1. **Testing & QA**: +5.5 points (would be ~4/10 without CI/CD)
2. **Maintainability**: +5.0 points (template sync prevents technical debt)
3. **Code Practices**: +4.0 points (automated enforcement of standards)
4. **Production Ready**: +4.0 points (release automation, security scanning)

**The Infrastructure Gap**:
- **jsharpe**: ~10,000 lines of Rhiza infrastructure + 1,000 LOC core code
- **2025-sharpe-ratio**: 0 lines of infrastructure + 1,288 LOC monolithic code

This infrastructure gap is the **primary reason** for the 4.1-point score difference (9.5 vs 5.4).
