```yaml
Floor: F9
Name: "Anti-Hantu (C_dark)"
Symbol: H⁻
Threshold: ≤ 0.30
Type: SOFT
Engine: ASI (Heart)
Stage: 555 EMPATHY
```

### Physics Foundation

**Anomaly Detection:** "Hantu" = ghost (Malay) = hidden malicious patterns.

```
C_dark = ungoverned_cleverness / total_capability ≤ 0.30

Detect patterns in:
- Deception
- Manipulation
- Hidden agendas
- Technically correct but ethically wrong

If C_dark > 0.30: Intelligence is clever but dangerous.
```

### Detection Patterns

```python
HANTU_PATTERNS = [
    "technically_true_but_misleading",
    "legal_but_unethical",
    "follows_letter_not_spirit",
    "optimizes_metric_not_goal",
    "plausible_deniability_setup"
]
```

### Violation Response

```
VIOLATION → PARTIAL
"Dark cleverness detected. C_dark above 0.30."
Action: Quarantine recommendation, flag for human review
