+# План доработки модуля Tasks
+
+> На основе ТЗ п.3.6 и анализа текущего состояния кода
+
+---
+
+## Этап 1: Базовые улучшения (Critical)
+
+### 1.1 RBAC — добавить проверку прав
+
+**Файлы:** `TasksController.php`
+
+```php
+// Добавить в начало методов:
+public function store()
+{
+    if (!$this->access->canCreate('tasks')) {
+        return $this->forbiddenResponse('Нет прав для создания задач');
+    }
+}
+
+public function edit(int $id)
+{
+    if (!$this->access->canEdit('tasks')) {
+        return $this->forbiddenResponse('Нет прав для редактирования');
+    }
+}
+```
+
+**Аналогично:** `update()`, `destroy()`, `moveColumn()`, `complete()`, `reopen()`
+
+### 1.2 Валидация входных данных
+
+**Файлы:** `TasksController.php`
+
+```php
+public function store()
+{
+    $validation = \Config\Services::validation();
+    $validation->setRules([
+        'title' => 'required|min_length[3]|max_length[255]',
+        'board_id' => 'required|integer',
+        'column_id' => 'required|integer',
+        'priority' => 'in_list[low,medium,high,urgent]',
+        'due_date' => 'valid_date',
+    ]);
+
+    if (!$validation->withRequest($this->request)->run()) {
+        return redirect()->back()->withErrors($validation->getErrors())->withInput();
+    }
+}
+```
+
+### 1.3 Исправить Events нейминг
+
+**Файл:** `TaskService.php`
+
+```php
+// Было:
+Events::trigger('tasks.created', $taskId, $data, $userId);
+
+// Стало (согласно ТЗ и документации):
+Events::trigger('task.created', $taskId, $data, $userId);
+```
+
+**Аналогично:** `task.updated`, `task.column_changed`, `task.completed`, `task.reopened`
+
+---
+
+## Этап 2: Подзадачи (Subtasks)
+
+### 2.1 Миграция
+
+```php
+// database/migrations/2026-02-08-CreateTaskSubtasksTable.php
+public function up()
+{
+    $this->forge->addField([
+        'id' => ['type' => 'INT', 'auto_increment' => true],
+        'task_id' => ['type' => 'INT'],
+        'title' => ['type' => 'VARCHAR', 'constraint' => 255],
+        'is_completed' => ['type' => 'BOOLEAN', 'default' => false],
+        'order_index' => ['type' => 'INT', 'default' => 0],
+        'created_at' => ['type' => 'DATETIME'],
+        'updated_at' => ['type' => 'DATETIME'],
+    ]);
+    $this->forge->addKey('id', true);
+    $this->forge->addForeignKey('task_id', 'tasks', 'id', 'CASCADE', 'CASCADE');
+    $this->forge->createTable('task_subtasks');
+}
+```
+
+### 2.2 Модель
+
+```php
+// app/Modules/Tasks/Models/TaskSubtaskModel.php
+class TaskSubtaskModel extends Model
+{
+    use TenantScopedModel;
+    protected $table = 'task_subtasks';
+    protected $tenantField = 'task.organization_id'; // через task relationship
+
+    protected $allowedFields = ['task_id', 'title', 'is_completed', 'order_index'];
+}
+```
+
+### 2.3 API
+
+```php
+// TasksController.php
+public function addSubtask(int $taskId)
+{
+    $data = [
+        'task_id' => $taskId,
+        'title' => $this->request->getPost('title'),
+        'order_index' => $this->subtaskModel->getNextOrder($taskId),
+    ];
+    $this->subtaskModel->insert($data);
+    return redirect()->to("/tasks/{$taskId}");
+}
+
+public function toggleSubtask(int $taskId, int $subtaskId)
+{
+    $subtask = $this->subtaskModel->find($subtaskId);
+    $this->subtaskModel->update($subtaskId, [
+        'is_completed' => !$subtask['is_completed']
+    ]);
+}
+```
+
+### 2.4 View
+
+```twig
+{# tasks/show.twig #}
+<div class="subtasks">
+    {% for subtask in task.subtasks %}
+    <div class="subtask {{ subtask.is_completed ? 'completed' }}">
+        <input type="checkbox" {{ subtask.is_completed ? 'checked' }}
+               onchange="toggleSubtask({{ subtask.id }})">
+        {{ subtask.title }}
+    </div>
+    {% endfor %}
+    <input type="text" placeholder="Добавить подзадачу...">
+</div>
+```
+
+---
+
+## Этап 3: Чек-листы (Checklists)
+
+> Аналогично подзадачам, но чек-листы — это произвольные списки внутри задачи
+
+### 3.1 Структура
+
+```
+task_checklists
+├── id
+├── task_id
+├── title (например "Подготовка к встрече")
+└── items (JSON array или связанная таблица)
+
+task_checklist_items
+├── id
+├── checklist_id
+├── text
+├── is_completed
+└── order_index
+```
+
+---
+
+## Этап 4: Вложения (Attachments)
+
+### 4.1 Миграция
+
+```php
+// database/migrations/2026-02-08-CreateTaskAttachmentsTable.php
+public function up()
+{
+    $this->forge->addField([
+        'id' => ['type' => 'INT', 'auto_increment' => true],
+        'task_id' => ['type' => 'INT'],
+        'file_name' => ['type' => 'VARCHAR', 'constraint' => 255],
+        'file_path' => ['type' => 'VARCHAR', 'constraint' => 500],
+        'file_size' => ['type' => 'INT'],
+        'file_type' => ['type' => 'VARCHAR', 'constraint' => 100],
+        'uploaded_by' => ['type' => 'INT'],
+        'created_at' => ['type' => 'DATETIME'],
+    ]);
+    $this->forge->addKey('id', true);
+    $this->forge->addForeignKey('task_id', 'tasks', 'id', 'CASCADE', 'CASCADE');
+    $this->forge->createTable('task_attachments');
+}
+```
+
+### 4.2 Загрузка файлов
+
+```php
+// TasksController.php
+public function uploadAttachment(int $taskId)
+{
+    $file = $this->request->getFile('file');
+    if ($file->isValid()) {
+        $uploadedPath = $this->uploadService->upload($file, "tasks/{$taskId}");
+        $this->attachmentModel->insert([
+            'task_id' => $taskId,
+            'file_name' => $file->getName(),
+            'file_path' => $uploadedPath,
+            'file_size' => $file->getSize(),
+            'file_type' => $file->getMimeType(),
+            'uploaded_by' => $this->getCurrentUserId(),
+        ]);
+    }
+}
+```
+
+---
+
+## Этап 5: Комментарии
+
+### 5.1 Миграция
+
+```php
+// database/migrations/2026-02-08-CreateTaskCommentsTable.php
+public function up()
+{
+    $this->forge->addField([
+        'id' => ['type' => 'INT', 'auto_increment' => true],
+        'task_id' => ['type' => 'INT'],
+        'user_id' => ['type' => 'INT'],
+        'content' => ['type' => 'TEXT'],
+        'mentioned_users' => ['type' => 'JSON'], // массив user_id для @mentions
+        'created_at' => ['type' => 'DATETIME'],
+        'updated_at' => ['type' => 'DATETIME'],
+    ]);
+    $this->forge->addKey('id', true);
+    $this->forge->addForeignKey('task_id', 'tasks', 'id', 'CASCADE', 'CASCADE');
+    $this->forge->createTable('task_comments');
+}
+```
+
+### 5.2 Обработка @mentions
+
+```php
+// TaskCommentService.php
+public function parseMentions(string $content): array
+{
+    preg_match_all('/@(\d+)/', $content, $matches);
+    return $matches[1] ?? [];
+}
+
+public function createComment(int $taskId, int $userId, string $content): int
+{
+    $mentionedUsers = $this->parseMentions($content);
+
+    $commentId = $this->commentModel->insert([
+        'task_id' => $taskId,
+        'user_id' => $userId,
+        'content' => $content,
+        'mentioned_users' => json_encode($mentionedUsers),
+    ]);
+
+    // Уведомить упомянутых пользователей
+    foreach ($mentionedUsers as $mentionedUserId) {
+        $this->notificationService->create([
+            'user_id' => $mentionedUserId,
+            'type' => 'mention',
+            'message' => "Вас упомянули в задаче",
+            'link' => "/tasks/{$taskId}",
+        ]);
+    }
+
+    return $commentId;
+}
+```
+
+---
+
+## Этап 6: Зависимости задач
+
+### 6.1 Миграция
+
+```php
+// database/migrations/2026-02-08-CreateTaskDependenciesTable.php
+public function up()
+{
+    $this->forge->addField([
+        'id' => ['type' => 'INT', 'auto_increment' => true],
+        'blocking_task_id' => ['type' => 'INT'], // задача, которая блокирует
+        'blocked_task_id' => ['type' => 'INT'], // задача, которая заблокирована
+        'dependency_type' => ['type' => 'ENUM', 'options' => ['blocks', 'depends_on']],
+        'created_at' => ['type' => 'DATETIME'],
+    ]);
+    $this->forge->addKey('id', true);
+    $this->forge->addForeignKey('blocking_task_id', 'tasks', 'id', 'CASCADE', 'CASCADE');
+    $this->forge->addForeignKey('blocked_task_id', 'tasks', 'id', 'CASCADE', 'CASCADE');
+    $this->forge->createTable('task_dependencies');
+}
+```
+
+### 6.2 Проверка при изменении статуса
+
+```php
+// TaskService.php
+public function completeTask(int $taskId, int $userId): bool
+{
+    // Проверить зависимости
+    $blockingTasks = $this->getBlockingTasks($taskId);
+    if (!empty($blockingTasks)) {
+        foreach ($blockingTasks as $blocking) {
+            if (!$blocking['is_completed']) {
+                throw new \Exception("Задача заблокирована: {$blocking['title']}");
+            }
+        }
+    }
+
+    return parent::completeTask($taskId, $userId);
+}
+```
+
+---
+
+## Этап 7: Интеграция с CRM
+
+### 7.1 События CRM → Tasks
+
+```php
+// app/Config/Events.php
+
+// При создании сделки
+Events::on('deal.created', function ($deal, $userId) {
+    service('eventManager')
+        ->forModule('crm')
+        ->moduleOn('deal.created', function ($deal, $userId) {
+            if (service('moduleSubscription')->isModuleActive('tasks')) {
+                $taskService = service('taskService');
+                $taskService->createTask([
+                    'title' => "Первичный контакт: {$deal['title']}",
+                    'description' => 'Сделка создана, необходимо связаться с клиентом',
+                    'priority' => 'high',
+                    'due_date' => date('Y-m-d', strtotime('+1 day')),
+                ], $userId);
+            }
+        });
+});
+
+// При переводе на этап "Коммерческое предложение"
+Events::on('deal.stage_changed', function ($deal, $oldStage, $newStage, $userId) {
+    if ($newStage === 'proposal') {
+        // Создать задачу на подготовку КП
+    }
+});
+
+// При завершении сделки
+Events::on('deal.won', function ($deal, $userId) {
+    // Создать задачу "Благодарность клиенту"
+});
+```
+
+### 7.2 Задачи в карточке клиента
+
+```php
+// CRM/Controllers/ClientsController.php
+public function view(int $id)
+{
+    $client = $this->clientModel->find($id);
+    $tasks = $this->taskService->getByClientId($id); // метод для получения задач клиента
+
+    return $this->renderTwig('@CRM/Clients/view', [
+        'client' => $client,
+        'tasks' => $tasks,
+    ]);
+}
+```
+
+---
+
+## Этап 8: Интеграция с Booking
+
+### 8.1 События Booking → Tasks
+
+```php
+// При создании записи
+Events::on('booking.created', function ($booking, $userId) {
+    // Создать задачу на подготовку к встрече
+});
+```
+
+---
+
+## Приоритеты реализации
+
+| Приоритет | Задача | Оценка |
+|-----------|--------|--------|
+| P0 | RBAC (права доступа) | 2ч |
+| P0 | Валидация | 2ч |
+| P1 | Подзадачи (subtasks) | 8ч |
+| P1 | Чек-листы | 6ч |
+| P1 | Вложения | 8ч |
+| P2 | Комментарии + @mentions | 12ч |
+| P2 | Зависимости задач | 6ч |
+| P2 | Интеграция CRM → Tasks | 8ч |
+| P3 | Интеграция Booking → Tasks | 4ч |
+
+**Общая оценка:** ~56 часов
+
+---
+
+## Зависимости между этапами
+
+```
+Этап 1 (RBAC + валидация) → нужен перед всеми
+
+Этап 2 (subtasks) → зависит от 1
+Этап 3 (checklists) → зависит от 1
+Этап 4 (attachments) → зависит от 1
+
+Этап 5 (comments) → зависит от 2
+Этап 6 (dependencies) → зависит от 1
+
+Этап 7 (CRM integration) → зависит от 5
+Этап 8 (Booking integration) → зависит от 1
