tui rework

- Standardized task log, LLM provider, and report profile tests.
- Relocated auxiliary tests into __tests__ directories for consistency.
- Updated git_service and defensive guards with minor stability fixes discovered during testing.
- Added UX integration tests for the reports list component.

+
+## 🚀 Быстрый старт
 
 ### Требования
+
+**Локальная разработка:**
 - Python 3.9+
 - Node.js 18+
 - npm
+- 2 GB RAM (минимум)
+- 5 GB свободного места
+
+**Docker (рекомендуется):**
+- Docker Engine 24+
+- Docker Compose v2
+- 4 GB RAM (для стабильной работы)
+
+### Установка и запуск
+
+#### Вариант 1: Docker (рекомендуется)
 
-### Запуск backend + frontend одним скриптом
 ```bash
-./run.sh
-```
+# Клонирование репозитория
+git clone <repository-url>
+cd ss-tools
 
-Что делает `run.sh`:
-- проверяет версии Python/npm;
-- создает `backend/.venv` (если нет);
-- устанавливает `backend/requirements.txt` и `frontend` зависимости;
-- запускает backend и frontend параллельно.
-
-Опции:
-- `./run.sh --skip-install` — пропустить установку зависимостей.
-- `./run.sh --help` — показать справку.
-
-Переменные окружения для локального запуска:
-- `BACKEND_PORT` (по умолчанию `8000`)
-- `FRONTEND_PORT` (по умолчанию `5173`)
-- `POSTGRES_URL`
-- `DATABASE_URL`
-- `TASKS_DATABASE_URL`
-- `AUTH_DATABASE_URL`
-
-## Docker
-
-### Запуск
-```bash
+# Запуск всех сервисов
 docker compose up --build
+
+# После запуска:
+# Frontend: http://localhost:8000
+# Backend API: http://localhost:8001
+# PostgreSQL: localhost:5432
 ```
 
-После старта сервисы доступны по адресам:
-- Frontend: `http://localhost:8000`
-- Backend API: `http://localhost:8001`
-- PostgreSQL: `localhost:5432` (`postgres/postgres`, БД `ss_tools`)
+#### Вариант 2: Локально
 
-### Остановка
-```bash
-docker compose down
-```
-
-### Очистка БД-тома
-```bash
-docker compose down -v
-```
-
-### Альтернативный образ PostgreSQL
-Если есть проблемы с pull `postgres:16-alpine`:
-```bash
-POSTGRES_IMAGE=mirror.gcr.io/library/postgres:16-alpine docker compose up -d db
-```
-или
-```bash
-POSTGRES_IMAGE=bitnami/postgresql:latest docker compose up -d db
-```
-
-Если порт `5432` занят:
-```bash
-POSTGRES_HOST_PORT=5433 docker compose up -d db
-```
-
-## Разработка
-
-### Ручной запуск сервисов
 ```bash
+# Backend
 cd backend
 python3 -m venv .venv
 source .venv/bin/activate
 pip install -r requirements.txt
 python3 -m uvicorn src.app:app --reload --port 8000
-```
 
-В другом терминале:
-```bash
+# Frontend (в новом терминале)
 cd frontend
 npm install
 npm run dev -- --port 5173
 ```
 
-### Тесты
-Backend:
-```bash
-cd backend
-source .venv/bin/activate
-pytest
-```
+### Первичная настройка
 
-Frontend:
-```bash
-cd frontend
-npm run test
-```
-
-## Инициализация auth (опционально)
 ```bash
+# Инициализация БД
 cd backend
 source .venv/bin/activate
 python src/scripts/init_auth_db.py
+
+# Создание администратора
 python src/scripts/create_admin.py --username admin --password admin
 ```
 
-## Миграция legacy-данных (опционально)
+## 🏢 Enterprise Clean Deployment (internal-only)
+
+Для разворота в корпоративной сети используйте профиль enterprise clean:
+
+- очищенный дистрибутив без test/demo/load-test данных;
+- запрет внешних интернет-источников;
+- загрузка ресурсов только с внутренних серверов компании;
+- обязательная блокирующая проверка clean/compliance перед выпуском.
+
+Быстрый запуск TUI-проверки:
+
 ```bash
-cd backend
-source .venv/bin/activate
-PYTHONPATH=. python src/scripts/migrate_sqlite_to_postgres.py --sqlite-path tasks.db
+cd /home/busya/dev/ss-tools
+./backend/.venv/bin/python3 -m backend.src.scripts.clean_release_tui
 ```
 
-## Дополнительная документация
-- `docs/plugin_dev.md`
-- `docs/settings.md`
-- `semantic_protocol.md`
+Типовые внутренние источники:
+- `repo.intra.company.local`
+- `artifacts.intra.company.local`
+- `pypi.intra.company.local`
+
+Если найден внешний endpoint, выпуск получает статус `BLOCKED` до исправления.
+
+## 📖 Документация
+
+- [Установка и настройка](docs/installation.md)
+- [Архитектура системы](docs/architecture.md)
+- [Разработка плагинов](docs/plugin_dev.md)
+- [API документация](http://localhost:8001/docs)
+- [Настройка окружений](docs/settings.md)
+
+## 🧪 Тестирование
+
+```bash
+# Backend тесты
+cd backend
+source .venv/bin/activate
+pytest
+
+# Frontend тесты
+cd frontend
+npm run test
+
+# Запуск конкретного теста
+pytest tests/test_auth.py::test_create_user
+```
+
+
+
+## 🔐 Авторизация
+
+Система поддерживает два метода аутентификации:
+
+1. **Локальная аутентификация** (username/password)
+2. **ADFS SSO** (Active Directory Federation Services)
+
+### Управление пользователями и ролями
+
+```bash
+# Получение списка пользователей
+GET /api/admin/users
+
+# Создание пользователя
+POST /api/admin/users
+{
+  "username": "newuser",
+  "email": "user@example.com",
+  "password": "password123",
+  "roles": ["analyst"]
+}
+
+# Создание роли
+POST /api/admin/roles
+{
+  "name": "analyst",
+  "permissions": ["dashboards:read", "dashboards:write"]
+}
+```
+
+## 📊 Мониторинг
+
+### Отчеты о задачах
+
+```bash
+# Список всех отчетов
+GET /api/reports?page=1&page_size=20
+
+# Детали отчета
+GET /api/reports/{report_id}
+
+# Фильтры
+GET /api/reports?status=failed&task_type=validation&date_from=2024-01-01
+```
+
+### Активность
+
+- **Dashboard Hub** — управление дашбордами с Git-статусом
+- **Dataset Hub** — управление датасетами с прогрессом маппинга
+- **Task Drawer** — мониторинг выполнения фоновых задач
+- **Unified Reports** — унифицированные отчеты по всем типам задач
+
+## 🔄 Обновление системы
+
+```bash
+# Обновление Docker контейнеров
+docker compose pull
+docker compose up -d
+
+# Обновление зависимостей Python
+cd backend
+source .venv/bin/activate
+pip install -r requirements.txt --upgrade
+
+# Обновление зависимостей Node.js
+cd frontend
+npm install
