## State Management

### Dialog States:

```tsx
// Company delete dialog
const [deleteDialogOpen, setDeleteDialogOpen] = useState(false);

// User delete dialog
const [deleteUserDialog, setDeleteUserDialog] = useState<{ 
    open: boolean; 
    user: CoreUser | null 
}>({ open: false, user: null });

// Role delete dialog
const [deleteRoleDialog, setDeleteRoleDialog] = useState<{ 
    open: boolean; 
    role: Role | null 
}>({ open: false, role: null });

// Active tab
const [activeTab, setActiveTab] = useState<
    'overview' | 'users' | 'roles' | 'hierarchy'
>('overview');
```

---

## Handler Functions

### User Handlers:

```tsx
// Delete user
const handleDeleteUser = (user: CoreUser) => {
    setDeleteUserDialog({ open: true, user });
};

const confirmDeleteUser = () => {
    if (deleteUserDialog.user) {
        router.delete(`/core/companies/${company.id}/users/${deleteUserDialog.user.id}`);
    }
};

// Toggle user status
const handleToggleUserStatus = (userId: number, isActive: boolean) => {
    const action = isActive ? 'deactivate' : 'activate';
    router.post(`/core/companies/${company.id}/users/${userId}/${action}`);
};
```

### Role Handlers:

```tsx
// Delete role
const handleDeleteRole = (role: Role) => {
    setDeleteRoleDialog({ open: true, role });
};

const confirmDeleteRole = () => {
    if (deleteRoleDialog.role) {
        router.delete(`/core/companies/${company.id}/roles/${deleteRoleDialog.role.id}`);
    }
};
```

---

## Backend Support

### CompanyController::show()

```php
public function show(int $id): Response
{
    $company = $this->companyService->getCompanyById($id);
    $statistics = $this->companyService->getCompanyStatistics($id);
    
    // Load company users with roles
    $users = $company->users()->with('roles')->get();
    
    // Load company roles with hierarchy
    $roles = $company->roles()->with('parent', 'children')->get();
    
    // Build role hierarchy tree
    $roleHierarchy = $company->roles()->rootRoles()->with('allChildren')->get();
    
    return Inertia::render('Core/Companies/Show', [
        'company' => $company->load('users', 'roles'),
        'statistics' => $statistics,
        'users' => $users,
        'roles' => $roles,
        'roleHierarchy' => $roleHierarchy,
    ]);
}
```

**Data Loaded:**
- ✅ Company with users and roles relationships
- ✅ Statistics (total_users, active_users, total_roles, etc.)
- ✅ All company users with their assigned roles
- ✅ All company roles with parent/children relationships
- ✅ Role hierarchy tree (root roles with all descendants)

---

## Empty States

Each tab has a user-friendly empty state:

### Users Tab - No Users
```
No users found for this company.
[Add First User Button]
```

### Roles Tab - No Roles
```
No roles found for this company.
[Create First Role Button]
```

### Hierarchy Tab - No Hierarchy
```
No role hierarchy found.
Create roles to build your company's hierarchy structure.
[Create First Role Button]
```

---

## Delete Confirmations

### User Delete Dialog
```
Title: Delete User
Description: Are you sure you want to delete "[User Name]"? 
This will revoke their access immediately.
Actions: [Cancel] [Delete]
```

### Role Delete Dialog
```
Title: Delete Role
Description: Are you sure you want to delete role "[Role Name]"? 
All users with this role will lose their permissions.
Actions: [Cancel] [Delete]
```

## Current Route Structure

### Users (Using Legacy Routes for Now)
- Create: `/core/users/create`
- Edit: `/core/users/{id}/edit`
- Delete: `DELETE /core/companies/{company}/users/{user}` (company-scoped)
- Toggle: `POST /core/companies/{company}/users/{user}/{action}` (company-scoped)

### Roles (Using Legacy Routes for Now)
- Create: `/core/roles/create`
- Edit: `/core/roles/{id}/edit`
- Delete: `DELETE /core/companies/{company}/roles/{role}` (company-scoped)

**Note:** Delete and toggle actions use the new company-scoped routes, while create/edit still use the legacy routes for backward compatibility.
