## Appendix C: Statistical Methodology

### C.1 Hypothesis Testing

**Primary Test:** Welch's two-sample t-test (unequal variances)

```python
from scipy import stats

# Example: Full SCAK vs No Semantic Purge
full_scak = [0.70, 0.74, 0.68, 0.76, 0.72]
no_purge = [0.66, 0.72, 0.64, 0.70, 0.68]

t_stat, p_value = stats.ttest_ind(full_scak, no_purge, equal_var=False)
# Result: t=2.486, p=0.0418
```

**Alternative Test:** Mann-Whitney U (non-parametric, if normality violated)

```python
u_stat, p_value = stats.mannwhitneyu(full_scak, no_purge, alternative='two-sided')
```

### C.2 Multiple Comparison Correction

**Method:** Bonferroni correction for 5 ablation comparisons

```python
alpha_original = 0.05
n_comparisons = 5
alpha_corrected = alpha_original / n_comparisons  # 0.01

# All reported p-values significant at α=0.05; 
# After Bonferroni: No Teacher, No Audit remain significant at α=0.01
```

### C.3 Effect Size (Cohen's d)

```python
import numpy as np

def cohens_d(group1, group2):
    n1, n2 = len(group1), len(group2)
    var1, var2 = np.var(group1, ddof=1), np.var(group2, ddof=1)
    pooled_std = np.sqrt(((n1-1)*var1 + (n2-1)*var2) / (n1+n2-2))
    return (np.mean(group1) - np.mean(group2)) / pooled_std

# Interpretation:
# |d| < 0.2: negligible
# |d| 0.2-0.5: small
# |d| 0.5-0.8: medium
# |d| > 0.8: large
```

### C.4 Confidence Intervals (Bootstrap)

```python
import numpy as np

def bootstrap_ci(data, n_bootstrap=10000, alpha=0.05):
    rng = np.random.default_rng(42)
    means = [np.mean(rng.choice(data, len(data), replace=True)) 
             for _ in range(n_bootstrap)]
    return np.percentile(means, [100*alpha/2, 100*(1-alpha/2)])

# Example: 95% CI for correction rate
ci = bootstrap_ci([0.70, 0.74, 0.68, 0.76, 0.72])
# Result: [0.686, 0.754]
```

## Appendix F: Broader Impact Statement

### Positive Impacts
- **Reliability:** Reduces agent failures in production, improving user trust
- **Efficiency:** Context reduction lowers costs and latency
- **Safety:** Governance layer prevents harmful outputs

### Potential Risks
- **Over-reliance:** Users may trust self-correcting agents too much
- **Teacher Dependency:** Concentration of power in teacher model providers
- **Adversarial Exploitation:** Patch injection attacks (see Limitations)

### Mitigations
- Human-in-the-loop for high-stakes decisions
- Multi-teacher ensemble to reduce single-provider dependency
- Patch provenance tracking and anomaly detection
