"text": "Perfect! Now I have enough information to provide a comprehensive overview. Let me compile this into a clear report.\n\n## Comprehensive Code Architecture Analysis\n\nI've thoroughly explored the project's CRUD operations, table views, and architectural patterns. Here's a detailed breakdown:\n\n### 1. CRUD Pattern: Controller → UseCase → Repository → Entity\n\n**Example Flow: Tasks**\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/Controller\/Api\/TaskController.php`** (Lines 20-52)\n```php\npublic function __construct(\n GetTasksUseCase $getTasksUseCase,\n CreateTaskUseCase $createTaskUseCase,\n DeleteTaskUseCase $deleteTaskUseCase,\n AssignTaskUseCase $assignTaskUseCase,\n UpdateTaskStatusUseCase $updateStatusUseCase,\n SaveTaskResultUseCase $saveResultUseCase,\n ExecuteAITaskUseCase $executeAIUseCase,\n TaskRepository $taskRepository,\n TaskResultRepository $resultRepository\n)\n```\n- **Controller** uses dependency injection to receive UseCases and Repositories\n- **HTTP Endpoints**: `index()`, `show()`, `store()`, `update()`, `destroy()` follow REST conventions\n- **Error Handling**: Try-catch blocks with proper HTTP status codes (201 for create, 404 for not found, 400 for validation)\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/UseCases\/Task\/GetTasksUseCase.php`**\n```php\nclass GetTasksUseCase {\n public function __construct(\n private TaskRepositoryInterface $taskRepository,\n private TaskAssignmentRepository $assignmentRepository,\n private TaskResultRepository $resultRepository\n ) {}\n \n public function execute(array $filters = [], int $limit = 50, int $offset = 0): array {\n return $this->taskRepository->findAll($filters, $limit, $offset);\n }\n \n public function getTaskWithDetails(int $id): ?array {\n \/\/ Complex query aggregating Task + Assignments + Results + Subtasks\n return [\n 'task' => $task->toArray(),\n 'assignments' => array_map(...),\n 'results' => array_map(...),\n 'subtasks' => array_map(...),\n ];\n }\n}\n```\n- **UseCase**: Orchestrates repository calls, applies business logic\n- **Composition**: Combines data from multiple repositories\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/Infrastructure\/Persistence\/TaskRepository.php`**\n```php\npublic function findAll(array $filters = [], int $limit = 50, int $offset = 0): array {\n \/\/ Dynamic WHERE clause building\n if (isset($filters['status'])) {\n $where[] = 'status = :status';\n $params['status'] = $filters['status'];\n }\n if (isset($filters['search'])) {\n $where[] = '(title LIKE :search OR description LIKE :search)';\n $params['search'] = '%' . $filters['search'] . '%';\n }\n \/\/ Prepared statement execution with bound parameters\n $sql = \"SELECT * FROM tasks {$whereClause} ORDER BY created_at DESC LIMIT :limit OFFSET :offset\";\n}\n\npublic function save(Task $task): int {\n \/\/ INSERT with UUID generation\n return (int) $this->pdo->lastInsertId();\n}\n\npublic function update(Task $task): bool {\n \/\/ UPDATE all mutable fields\n return $stmt->execute([...]);\n}\n\npublic function delete(int $id): bool {\n return $stmt->execute(['id' => $id]);\n}\n```\n- **Repository**: Direct PDO queries with prepared statements\n- **Filtering**: Dynamic WHERE clause building from filters array\n- **Pagination**: LIMIT and OFFSET support\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/Domain\/Entity\/Task.php`**\n```php\nclass Task {\n private ?int $id = null;\n private string $uuid;\n private string $title;\n private TaskStatus $status; \/\/ Value Object\n \/\/ ... other properties\n \n public function toArray(): array { \/* serialization *\/ }\n public static function fromArray(array $data): self { \/* deserialization *\/ }\n}\n```\n- **Entity**: Type-safe with ValueObjects (`TaskStatus`)\n- **Serialization**: `toArray()` and `fromArray()` methods\n\n---\n\n### 2. DI Registration Pattern (services.php)\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/services.php`**\n\nThe container uses three registration strategies:\n\n**A. Database Connections**\n```php\n$container->set('pdo.dev', fn () => DatabaseFactory::dev());\n$container->set('pdo.content', fn () => DatabaseFactory::content());\n```\n\n**B. Concrete Repository Registration**\n```php\n$container->set(TaskRepository::class, fn () => new TaskRepository());\n$container->set(DokumentationRepository::class, fn () => new DokumentationRepository());\n```\n\n**C. Interface → Implementation Aliases**\n```php\n$container->set(TaskRepositoryInterface::class, fn (Container $c) => $c->get(TaskRepository::class));\n$container->set(ContentRepositoryInterface::class, fn (Container $c) => $c->get(ContentRepository::class));\n```\n\n**D. Service Factory Pattern (Complex Dependencies)**\n```php\n$container->set(ChatService::class, function (Container $c) {\n return $c->get(AIConfig::class)->createChatService();\n});\n\n$container->set(HybridSearchService::class, function (Container $c) {\n return new HybridSearchService(\n $c->get('pdo.dev'),\n $c->get(OllamaService::class)\n );\n});\n```\n\n**Key Design: UseCases Are Auto-Wired**\n```php\n\/\/ NOTE: UseCases are NOT explicitly registered here.\n\/\/ They are resolved via Container::autowire() automatically.\n\/\/ Only register: Interfaces, Services with special config, Repositories.\n```\n\n---\n\n### 3. Table View Rendering Pattern\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/View\/tasks\/index.php`**\n```php\n<?php ob_start(); ?>\n\n<h1>Tasks<\/h1>\n\n<!-- Stats Cards -->\n<div class=\"stats-grid\">\n <div class=\"stat-card\">\n <span class=\"stat-card__value\"><?= $stats['total'] ?? 0 ?><\/span>\n <span class=\"stat-card__label\">Gesamt<\/span>\n <\/div>\n<\/div>\n\n<!-- Filters -->\n<div class=\"filters\">\n <input type=\"search\" id=\"task-search\" class=\"form-input\">\n <select id=\"filter-status\" class=\"form-select--inline\">\n <option value=\"\">Alle Status<\/option>\n <option value=\"pending\">Offen<\/option>\n <\/select>\n<\/div>\n\n<!-- Table with data-sortable attribute -->\n<table id=\"task-table\" data-sortable>\n <thead>\n <tr>\n <th data-sort=\"id\">ID<\/th>\n <th data-sort=\"title\">Titel<\/th>\n <th data-sort=\"status\">Status<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <?php if (!empty($tasks)): ?>\n <?php foreach ($tasks as $task): ?>\n <tr>\n <td><a href=\"\/tasks\/<?= $task['id'] ?>\"><?= $task['id'] ?><\/a><\/td>\n <td><?= htmlspecialchars($task['title']) ?><\/td>\n <td><span class=\"badge badge--<?= $task['status'] ?>\"><?= $task['status'] ?><\/span><\/td>\n <\/tr>\n <?php endforeach; ?>\n <?php else: ?>\n <tr><td colspan=\"5\" class=\"empty-state\">Keine Tasks vorhanden<\/td><\/tr>\n <?php endif; ?>\n <\/tbody>\n<\/table>\n\n<!-- JavaScript Data Table Component -->\n<script type=\"module\">\nimport { init } from '\/js\/components\/data-table.js';\n\nconst dataTable = init({\n clock: { now_epoch_ms_utc: () => Date.now() },\n logger: console,\n ui: { showMessage: (msg) => { console.log(...); } }\n});\n\ndataTable.create('task-table', {\n searchInput: 'task-search',\n pageSize: 10,\n filters: {\n 'filter-status': 3, \/\/ Column index\n 'filter-type': 2\n }\n});\n<\/script>\n\n<?php $content = ob_get_clean(); ?>\n<?php require VIEW_PATH . '\/layout.php'; ?>\n```\n\n**Patterns:**\n- **Output Buffering**: `ob_start()` → `$content = ob_get_clean()` → Layout injection\n- **Empty States**: Conditional rendering with message\n- **Badge System**: Status-based CSS classes (`.badge--pending`, `.badge--completed`)\n- **Data Extraction**: Variables auto-extracted via `extract($data)` in Controller\n- **Client-Side Sorting\/Filtering**: JavaScript module initialization with column mappings\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/View\/contracts\/index.php`** (Similar pattern)\n- Stats cards showing counts by status\n- Filter dropdowns linked to table columns by ID\n- Responsive table with truncated content (e.g., `substr(..., 0, 50) . '...'`)\n\n---\n\n### 4. Docs\/Hierarchical View Pattern (Tree Rendering)\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/View\/docs\/index.php`**\n```php\n<?php\nfunction renderDocsToc(array $items, int $level = 1): string {\n if (empty($items)) {\n return '';\n }\n \n $html = '<ol class=\"docs-toc docs-toc-level-' . $level . '\">';\n foreach ($items as $item) {\n $html .= '<li>';\n $html .= '<a href=\"\/docs' . htmlspecialchars($item['path']) . '\">' . \n htmlspecialchars($item['title']) . '<\/a>';\n if (!empty($item['children'])) {\n $html .= renderDocsToc($item['children'], $level + 1); \/\/ Recursive!\n }\n $html .= '<\/li>';\n }\n $html .= '<\/ol>';\n return $html;\n}\n?>\n\n<?= renderDocsToc($hierarchy) ?>\n\n<?php require VIEW_PATH . '\/layout.php'; ?>\n```\n\n**Pattern:**\n- **Recursive Function**: Renders nested lists with CSS level tracking\n- **Data Hierarchy**: Repository provides nested array structure\n- **Path Building**: Each item has full path to navigate\n\n---\n\n### 5. Index\/Scan Pattern: Repository `findAll` Methods\n\n**File: `\/var\/www\/dev.campus.systemische-tools.de\/src\/Infrastructure\/Persistence\/ContractRepository.php`**\n```php\npublic function findAll(array $filters = [], int $limit = 50): array {\n $sql = 'SELECT * FROM contracts WHERE 1=1';\n $params = [];\n \n \/\/ Dynamic filter building\n if (isset($filters['status']) && $filters['status'] !== '') {\n $sql .= ' AND status = :status';\n $params['status'] = $filters['status'];\n }\n \n if (isset($filters['search']) && $filters['search'] !== '') {\n $sql .= ' AND (name LIKE :search OR scope_description LIKE :search2)';\n $params['search'] = '%' . $filters['search'] . '%';\n $params['search2'] = '%' . $filters['search'] . '%';\n }\n \n $sql .= ' ORDER BY name ASC, version DESC LIMIT :limit';\n \n $stmt = $this->pdo->prepare... [TRUNCATED-64628f93f193f8b1]"
