- 3 pre-existing findings (unrelated to Phase 2)
- No Critical or High severity issues

**JavaScript Scan:**

- ✅ No new issues in Phase 2 code
- 1 pre-existing finding (test file only)
- Low severity

### Go Vulnerability Check

## Database Migration Verification

### Test Database Setup

**Configuration:**

```go
dsn := "file::memory:?cache=shared"
db, err := gorm.Open(sqlite.Open(dsn), &gorm.Config{
    PrepareStmt: true,
})
```

**Results:**

- ✅ No "no such table" errors
- ✅ KeyVersion field created consistently
- ✅ AutoMigrate works in all test scenarios
- ✅ Connection pooling improves stability
- ✅ Tests are deterministic (no flakiness)

### Schema Verification

**DNSProvider Model:**

```go
type DNSProvider struct {
    ID                 uint   `gorm:"primarykey"`
    Name               string `gorm:"unique;not null"`
    ProviderType       string
    CredentialsEncrypted []byte   `json:"-"`
    KeyVersion         int      `gorm:"default:1;index"`
    // ... other fields
}
```

- ✅ KeyVersion field present
- ✅ Default value: 1
- ✅ Indexed for performance
- ✅ Backward compatible

---

## Regression Testing

### Existing Functionality

**DNS Provider CRUD:**

- ✅ Create: Works with KeyVersion=1
- ✅ Read: Retrieves providers correctly
- ✅ Update: Updates credentials and KeyVersion
- ✅ Delete: No impact from new field

**Encryption/Decryption:**

- ✅ Existing credentials decrypt correctly
- ✅ New credentials encrypted with version 1
- ✅ Version tracking works as expected

**API Endpoints:**

- ✅ All existing endpoints functional
- ✅ No breaking changes
- ✅ Response formats unchanged

### Phase 1 Integration

**Audit Logging:**

- ✅ Rotation events logged
- ✅ Actor, IP, user agent captured
- ✅ Operation details included
- ✅ Sensitive data not logged
