- **Budget-Aware Execution** (`budget_aware_execution.py`) - Cost-optimized selection

**Integration Status**: 
- ✅ Early stopping integrated with adaptive execution
- 🔄 Adaptive sampling ready for integration
- 🔄 MR prioritization ready for integration
- 🔄 Budget-aware ready for integration

### ✅ 5.2 Multi-Objective Optimization
- **Multi-Objective Analysis** (`multi_objective.py`) - Pareto frontiers
- **Trade-off Visualization** (`tradeoff_visualization.py`) - Analysis & export

**Integration Status**: 
- ✅ Modules exported and ready for use
- 🔄 Multi-objective gating ready for integration

### ✅ 5.3 Trust & Safety
- **Trust Scoring** (`trust_scoring.py`) - Enhanced RAG attribution
- **Safety Monitors** (`safety_monitors.py`) - Toxicity, bias, PII detection
- **Compliance Checks** (`compliance.py`) - GDPR, HIPAA, Financial
- **Enhanced Audit Trails** (`audit_enhanced.py`) - Tamper detection

**Integration Status**: 
- ✅ Safety monitors registered and available via CLI
- ✅ Trust scoring extends existing system
- 🔄 Compliance checks ready for integration
- 🔄 Enhanced audit ready for integration

## Test Results

✅ **All tests pass** (26 passed, 1 skipped)  
✅ **Safety monitors registered successfully**  
✅ **Early stopping integrated with adaptive execution**  
✅ **No linting errors**  
✅ **All modules import successfully**

## Usage

### CLI Usage

```bash
# Use safety monitors
metamorphic-guard evaluate \
  --task top_k \
  --baseline baseline.py \
  --candidate candidate.py \
  --monitor safety \
  --monitor toxicity:threshold=0.7

# Use adaptive testing (with automatic early stopping)
metamorphic-guard evaluate \
  --task top_k \
  --baseline baseline.py \
  --candidate candidate.py \
  --adaptive-testing \
  --adaptive-min-sample-size 50 \
  --adaptive-check-interval 25
```

### Programmatic Usage

```python
from metamorphic_guard import (
    run,
    TaskSpec,
    Implementation,
    SafetyMonitor,
    MultiObjectiveConfig,
    analyze_trade_offs,
)

# Use safety monitor
result = run(
    task=my_task,
    baseline=Implementation.from_path("baseline.py"),
    candidate=Implementation.from_path("candidate.py"),
    monitors=[SafetyMonitor()],
)

# Multi-objective analysis
from metamorphic_guard.multi_objective import CandidateMetrics, Objective

candidates = [
    CandidateMetrics(
        candidate_id="candidate_1",
        objectives={
            "pass_rate": Objective("pass_rate", 0.95, minimize=False),
            "cost": Objective("cost", 0.10, minimize=True),
        },
    ),
]

config = MultiObjectiveConfig(
    objectives=["pass_rate", "cost"],
    minimize={"cost": True},
)

analysis = analyze_trade_offs(candidates, config)
```
