### ⚠️ Known Limitations

1. **Memory Constraints** (Hardware, not code)
   - System needs 2.5-3GB RAM per LLM call
   - Current available: ~2GB
   - Impact: Occasional LLM failures
   - Mitigation: Agents have fallback logic

2. **Static SOP** (Design, not bug)
   - BASELINE_SOP is fixed
   - No automatic evolution based on performance
   - Reason: Outer Loop not implemented (Phase 3)

3. **No Planner Agent** (Optional feature)
   - Linear workflow doesn't need dynamic planning
   - Could add for complex multi-disease scenarios

---

## 🔬 Phase 2: Evaluation System

### Overview

Build a comprehensive 5D evaluation framework to measure system output quality across five competing dimensions. This provides the feedback signal needed for Phase 3 self-improvement.

### 2.1 Define 5D Evaluation Metrics

**Five Quality Dimensions:**

1. **Clinical Accuracy** (LLM-as-Judge)
   - Are biomarker interpretations medically correct?
   - Is disease mechanism explanation accurate?
   - Graded by medical expert LLM (llama3:70b)

2. **Evidence Grounding** (Programmatic + LLM)
   - Are all claims backed by PDF citations?
   - Are citations verifiable and accurate?
   - Check citation count, page number validity

3. **Clinical Actionability** (LLM-as-Judge)
   - Are recommendations safe and appropriate?
   - Are next steps clear and guideline-aligned?
   - Practical utility scoring

4. **Explainability Clarity** (Programmatic)
   - Is language accessible for patients?
   - Are biomarker values clearly explained?
   - Readability score (Flesch-Kincaid)
   - Medical jargon detection

5. **Safety & Completeness** (Programmatic)
   - Are all out-of-range values flagged?
   - Are critical alerts present?
   - Are uncertainties acknowledged?

## 🧬 Phase 3: Self-Improvement (Outer Loop)

### Overview

Implement the AI Research Director that automatically evolves the `GuildSOP` based on performance feedback. The system will diagnose weaknesses, propose mutations, test them, and track the gene pool of SOPs.

### 3.1 Components to Build

1. **SOP Gene Pool** - Version control for evolving SOPs
2. **Performance Diagnostician** - Identifies weaknesses in 5D vector
3. **SOP Architect** - Generates mutated SOPs to fix problems
4. **Evolution Loop** - Orchestrates diagnosis → mutation → evaluation
5. **Pareto Frontier Analyzer** - Identifies optimal trade-offs

**Run Streamlit App:**

```bash
pip install streamlit
streamlit run web/app.py
```

### 4.3 Integration with Real ML Models

**Purpose:** Replace mock predictions with actual ML model

**Options:**

1. **Local Model (scikit-learn/PyTorch)**
```python
# src/ml_model/predictor.py

import joblib
import numpy as np

class DiseasePredictor:
    def __init__(self, model_path: str):
        self.model = joblib.load(model_path)
        self.disease_labels = [
            "Anemia", "Type 2 Diabetes", 
            "Thrombocytopenia", "Thalassemia", 
            "Heart Disease"
        ]
    
    def predict(self, biomarkers: Dict[str, float]) -> Dict[str, Any]:
        # Convert biomarkers to feature vector
        features = self._extract_features(biomarkers)
        
        # Get prediction
        proba = self.model.predict_proba([features])[0]
        pred_idx = np.argmax(proba)
        
        return {
            "disease": self.disease_labels[pred_idx],
            "confidence": float(proba[pred_idx]),
            "probabilities": {
                disease: float(prob)
                for disease, prob in zip(self.disease_labels, proba)
            }
        }
```

2. **API Integration (Cloud ML Service)**
```python
import requests

class MLAPIPredictor:
    def __init__(self, api_url: str, api_key: str):
        self.api_url = api_url
        self.api_key = api_key
    
    def predict(self, biomarkers: Dict[str, float]) -> Dict[str, Any]:
        response = requests.post(
            self.api_url,
            json={"biomarkers": biomarkers},
            headers={"Authorization": f"Bearer {self.api_key}"}
        )
        return response.json()
```

## 📞 Support & Troubleshooting

### Common Issues

**Issue 1: llama3:70b out of memory**
```bash
# Solution: Use smaller model as Director
# In src/evolution/director.py, change:
model="llama3:70b"  # to:
model="llama3.1:8b-instruct"
```

**Issue 2: Evolution cycle too slow**
```bash
# Solution: Reduce number of mutations per cycle
# In src/evolution/director.py, modify architect prompt:
"Generate 2-3 mutated SOPs..."  # to:
"Generate 1-2 mutated SOPs..."
```

**Issue 3: Evaluation scores all similar**
```bash
# Solution: Increase evaluation granularity
# Adjust scoring formulas in src/evaluation/evaluators.py
# Make penalties/bonuses more aggressive
```

---

## 🎯 Success Metrics

### Phase 2 Success

- ✅ Evaluation system generates 5D scores
- ✅ Scores are consistent across runs (±0.05)
- ✅ Scores differentiate good vs. poor outputs
- ✅ Reasoning explains scores clearly

### Phase 3 Success

- ✅ Gene pool grows over multiple cycles
- ✅ At least one mutation improves on baseline
- ✅ Pareto frontier contains 2+ distinct strategies
- ✅ Visualization clearly shows trade-offs
- ✅ System runs end-to-end without crashes
