#### 3. **Email Verification**
**Status:** Model mendukung tapi tidak diimplementasikan
```
Masalah:

#### 4. **Password Reset**
**Status:** Route ada tapi view incomplete
```
Masalah:
- Route '/forgot-password' ada bener, tapi view 'auth.forgot-password' belum ada
- Password reset logic tidak final
- Tidak ada email notifications untuk password reset
```

#### 5. **Real Subscription Limits**
**Status:** Models sudah ada tapi belum enforce di logic
```
Masalah:
- Free plan harusnya limited jumlah analisis (misalnya 5/bulan)
- Pro plan unlimited tapi tidak ada limit lain
- Enterprise tidak ada fitur khusus
- Tidak ada enforcement di controller
- Tidak ada rate limiting
```
**Expected:**
- Free: max 5 analysis/bulan

#### 6. **API & Integration**
**Status:** Not started
```
Masalah:

#### 7. **Error Handling & Validation**
**Status:** Basic implementation
```
Masalah:

## 🐛 FITUR YANG TIDAK BERFUNGSI / BUG ISSUES

### **Confirmed Issues:**

#### 1. **Password Reset Flow Incomplete**
```
Location: routes/web.php line ~60
Issue: Route password.request ada tapi view 'auth.forgot-password' tidak ada
Expected: Full password reset flow dengan email
```

#### 2. **Email System** (Development Mode)
```
Location: config/mail.php
Issue: 'MAIL_MAILER' => 'log' (development setting)
Impact: Semua email hanya di-log ke log files, tidak terkirim
```

#### 3. **Division by Zero in Calculations**
```
Location: app/Services/AltmanZScoreService.php
Issue: 
$totalAset = $financialData['total_aset'] ?? 1; // Prevents division by zero but masks data issues
```

#### 4. **Dashboard Export**
```
Location: app/Http/Controllers/DashboardController.php line ~145
public function export()
{
    return back()->with('info', 'Fitur export sedang dalam pengembangan.');
}
Issue: Stub function, tidak ada implementasi
```

#### 5. **Incomplete Admin Routing**
```
Location: routes/web.php line ~150+
Issue: Admin routes tidak lengkap?

Dari web.php hanya ada:
- DashboardController, UserController, AnalysisController, SettingsController, ContactController

Tapi harusnya ada lebih banyak routes untuk CRUD operations
```

#### 6. **User Banning Not Enforced**
```
Location: app/Models/User.php
Issue: User memiliki is_banned flag tapi tidak ada middleware yang enforce
Expected: global middleware untuk check is_banned
```

#### 7. **Session-Based Analysis vs Database**
```
Location: app/Http/Controllers/AnalysisController.php
Issue: Analysis disimpan di session dulu baru di database
Problem: Session bisa expire, data hilang
Harusnya: Direct database storage atau better session handling
```

#### 8. **Incomplete Middleware Setup**
```
Issue: Tidak jelas middleware route protection:
- Only authenticated users should access analysis
- Only admins should access admin routes
- Maybe missing CORS middleware
```

#### 9. **No Database Constraints**
```
Issue: Tidak ada foreign key enforcement visible
Risk: Orphaned records, data integrity issues
```

#### 10. **Subscription Not Fully Enforced**
```
Issue: Free users bisa access pro features
Perlu: Middleware untuk check subscription level
Contoh: Unlimited analysis hanya untuk Pro/Enterprise
```

## 🔐 SECURITY CONCERNS

### **High Priority:**

1. **Email Verification Missing**
   - Anyone bisa register dengan fake email
   
2. **No Rate Limiting**
   - Bisa DDoS login, analysis endpoints
   
3. **No CSRF Token Validation Visible**
   - Assumed default Laravel, tapi perlu verify
   
4. **Webhook Signature Not Verified**
   - Midtrans webhook could be spoofed
   
5. **No Input Sanitization Visible**
   - Especially di search functionality
   
6. **Session Hijacking Risk**
   - No additional security headers visible (CSP, etc)

### **Medium Priority:**

7. **No 2FA**
8. **No Audit Logging**
9. **No IP Whitelisting**
10. **No API Key Rotation**

---

## 📊 DATABASE SCHEMA OBSERVATIONS

### **What's Missing:**

```sql
-- Tidak ada:

-- 1. User-Company relationship table (jika many-to-many)
-- 2. Audit log table
-- 3. Email verification tokens table
-- 4. Password reset tokens table
-- 5. API tokens table
-- 6. File uploads table
-- 7. Notifications table
-- 8. User preferences table
-- 9. Payment transaction history table (separate from subscription)
-- 10. Rate limit log table
```

### **Optimization Needed:**

```
-- Missing indexes:
- analysis_results: user_id, company_id, z_category, created_at
- subscriptions: user_id, status, expired_at
- companies: user_id, business_field
- contacts: read_at, status, created_at
```

---

## 💻 CODE QUALITY OBSERVATIONS

### **Positives:**
- ✅ Good use of Laravel conventions
- ✅ Model relationships properly established
- ✅ Service-based architecture for business logic
- ✅ Validation at form request level
- ✅ Good separation of concerns

### **Areas for Improvement:**
- ⚠️ Some error handling gaps
- ⚠️ No comprehensive logging
- ⚠️ Limited defensive programming (e.g., null checks)
- ⚠️ Magic numbers in calculations (Z-Score coefficients should be constants)
- ⚠️ Some code could be more DRY (Dashboard data building repeated)
- ⚠️ No comprehensive PHPDoc comments
- ⚠️ Incomplete type hints in some methods

**Example Issue - AltmanZScoreService:**
```php
// Magic numbers lebih baik jadi constants:
const COEFFICIENT_X1 = 1.2;
const COEFFICIENT_X2 = 1.4;
const COEFFICIENT_X3 = 3.3;
const COEFFICIENT_X4 = 0.6;
const COEFFICIENT_X5 = 1.0;

// Dan handling division by zero lebih baik:
if ($totalAset <= 0) {
    throw new \InvalidArgumentException('Total aset harus lebih dari 0');
}
```

## 🏗️ ARCHITECTURE & SCALABILITY

### **Current Architecture Issues:**

1. **Session-Based Analysis**
   - Doesn't scale dengan distributed systems
   - Risk session loss
   
2. **No Queue System Active**
   - PDF generation bisa block
   - Email would block
   - Payment processing bisa slow
   
3. **No Caching Layer**
   - Dashboard queries recalculate every time
   - Could be expensive at scale
   
4. **No API Versioning**
   - Future API changes bisa break clients
   
5. **No Database Read Replicas**
   - All reads dan writes ke same database

### **Recommended Improvements:**

```
1. Implement job queue untuk:
   - PDF generation
   - Email sending
   - Data exports
   - Payment webhooks

2. Add Redis caching untuk:
   - Dashboard statistics
   - User preferences
   - Payment status

3. Implement API versioning:
   - /api/v1/analyses
   - /api/v2/analyses (future)

4. Database optimization:
   - Add read replicas
   - Query optimization
   - Materialized views untuk analytics
```
