### Key Guards

#### Guard: HIPAACompliance

```rust
pub struct HIPAACompliance;

impl Guard for HIPAACompliance {
    fn check(&self, package: &Package) -> Result<ValidationReceipt, GuardError> {
        let mut receipt = ValidationReceipt::new();

        // 1. Encryption at rest
        self.check_encryption_at_rest(package)?;

        // 2. Encryption in transit (TLS 1.2+)
        self.check_tls_configuration(package)?;

        // 3. Access logs
        self.check_audit_trails(package)?;

        // 4. De-identification rules
        self.check_deidentification_logic(package)?;

        // 5. Data retention policies
        self.check_retention_policies(package)?;

        // 6. Breach notification procedures
        self.check_breach_procedures(package)?;

        Ok(receipt)
    }
}
```

#### Guard: FHIRConformance

```rust
pub struct FHIRConformance;

impl Guard for FHIRConformance {
    fn check(&self, package: &Package) -> Result<ValidationReceipt, GuardError> {
        // 1. Verify all FHIR resources use correct structure
        // 2. Validate JSON schema against FHIR spec
        // 3. Check cardinality of fields (1..1, 0..1, 0..*, 1..*)
        // 4. Ensure required fields are not nullable
        // 5. Verify constraint definitions match FHIR
        Ok(receipt)
    }
}
```

### Generated Code Example

From `healthcare:Patient` entity, generate:

**Rust**:
```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct Patient {
    pub id: String,
    pub first_name: String,
    pub last_name: String,
    pub date_of_birth: NaiveDate,
    pub mrn: String,  // Unique, validated
    pub addresses: Vec<Address>,
    pub telecom: Vec<Telecom>,
}

impl Patient {
    pub fn validate(&self) -> Result<(), PatientError> {
        // MRN format validation
        if !self.mrn.chars().all(|c| c.is_ascii_alphanumeric()) {
            return Err(PatientError::InvalidMrn);
        }

        // Age validation (minimum age constraint)
        let age = Local::now().date_naive().years_since(self.date_of_birth)
            .ok_or(PatientError::InvalidDateOfBirth)?;
        if age < 0 {
            return Err(PatientError::InvalidDateOfBirth);
        }

        Ok(())
    }
}

// Encrypted field handling
impl Patient {
    pub fn encrypt_pii(&mut self, key: &EncryptionKey) -> Result<(), EncryptionError> {
        self.first_name = encrypt(&self.first_name, key)?;
        self.last_name = encrypt(&self.last_name, key)?;
        self.date_of_birth = encrypt(&self.date_of_birth.to_string(), key)?;
        Ok(())
    }
}
```

**TypeScript**:
```typescript
export interface Patient {
    id: string;
    firstName: string;
    lastName: string;
    dateOfBirth: string;  // ISO 8601
    mrn: string;
    addresses: Address[];
    telecom: Telecom[];
}

export class PatientValidator {
    static validate(patient: Patient): ValidationError[] {
        const errors: ValidationError[] = [];

        // MRN validation
        if (!/^[A-Z0-9]+$/.test(patient.mrn)) {
            errors.push({ field: 'mrn', message: 'Invalid MRN format' });
        }

        // Date validation
        const dob = new Date(patient.dateOfBirth);
        if (isNaN(dob.getTime())) {
            errors.push({ field: 'dateOfBirth', message: 'Invalid date' });
        }

        return errors;
    }
}
```

### Dark Matter Reduction: Compliance Automation

**Before (Manual)**:
```
1. Review HIPAA requirements checklist (30 min)
2. Identify required fields for audit logs (20 min)
3. Write encryption wrapper classes (90 min)
4. Implement access log middleware (120 min)
5. Create breach notification logic (60 min)
6. Write compliance tests (120 min)
Total: ~8.5 hours
```

**After (ggen Bundle)**:
```
1. Apply HIPAACompliance guard (5 min)
   ✓ Audit log structure generated
   ✓ Encryption templates provided
   ✓ Breach notification scaffolds created
2. Customize compliance logic (20 min)
3. Run compliance tests (5 min)
   ✓ All generated, just verify
Total: ~30 minutes
```

**Reduction**: 94% (8.5 hours → 30 min)

## Microservices Bundle

### Bundle: `sector-rust-microservice-8020`

**Target**: Rust microservices with production patterns

- Observability setup: 85% reduction (8 hours → 1 hour)
- Health checks: 95% reduction (2 hours → 5 min)
- Graceful shutdown: 90% reduction (3 hours → 20 min)
