## 🔧 Technical Details

### Architecture: Service-Direct Pattern

```
User Browser
    ↓
EventRegistryPage (React)
    ↓
useAllAuditLogs() hook (React Query)
    ↓
auditLogsService.getAllAuditLogs()
    ↓
Promise.all() - Parallel Requests
    ├→ GET /tenants/{id}/sales/audit-logs
    ├→ GET /tenants/{id}/inventory/audit-logs
    ├→ GET /tenants/{id}/orders/audit-logs
    ├→ GET /tenants/{id}/production/audit-logs
    ├→ GET /tenants/{id}/recipes/audit-logs
    ├→ GET /tenants/{id}/suppliers/audit-logs
    ├→ GET /tenants/{id}/pos/audit-logs
    ├→ GET /tenants/{id}/training/audit-logs
    ├→ GET /tenants/{id}/notification/audit-logs
    ├→ GET /tenants/{id}/external/audit-logs
    └→ GET /tenants/{id}/forecasting/audit-logs
    ↓
Client-Side Aggregation
    ↓
Sort by created_at DESC
    ↓
Display in UI Table
```

### Performance
- **Parallel Requests**: ~200-500ms for all 11 services
- **Caching**: 30s for logs, 60s for statistics
- **Pagination**: Client-side (50 items per page default)
- **Fault Tolerance**: Graceful degradation on service failures

### Security
- **RBAC**: admin and owner roles only
- **Tenant Isolation**: Enforced at database query level
- **Authentication**: Required for all endpoints

---

## 🧪 Quick Test

### Backend Test (Terminal)
```bash
# Set your tenant ID and auth token
TENANT_ID="your-tenant-id"
TOKEN="your-auth-token"

# Test sales service audit logs
curl -H "Authorization: Bearer $TOKEN" \
     "https://localhost/api/v1/tenants/$TENANT_ID/sales/audit-logs?limit=10"

# Should return JSON array of audit logs
```

### Frontend Test (Browser)
1. Login as admin/owner
