# @BRIEF Enterprise Clean E2E Orchestrator — полный протокол тестирования пустого образа перед передачей.
#   Stage 1: Сборка dist bundle, развёртывание enterprise-clean стека, PostgreSQL, Playwright проверка
#            первоначальной настройки (StartupEnvironmentWizard), добавление Superset окружения.
#   Stage 2: Запуск ./run.sh (локальный dev стек), Playwright проверка живого проекта,
#            LLM анализ дашборда, изменение настроек.
# @PRE Docker и docker compose установлены. Node 20+, python3, .venv настроен.
# @POST Stage 1: Enterprise-clean bundle собран, развёрнут, протестирован, стек остановлен.
#       Stage 2: Локальный dev стек запущен, протестирован, остановлен.
# @SIDE_EFFECT Создаёт bundle в dist/docker/. Запускает и останавливает Docker контейнеры.
#   Останавливает dev процессы (uvicorn, vite). Использует временный PostgreSQL контейнер.
# @INVARIANT Stage 1 и Stage 2 выполняются последовательно. Ошибка в Stage 1 прерывает весь протокол.
# @INVARIANT После завершения (успех или ошибка) все контейнеры и процессы останавливаются.
# @LAYER Infrastructure
# @RELATION DEPENDS_ON -> [build.sh]
# @RELATION DEPENDS_ON -> [run.sh]
# @RELATION DEPENDS_ON -> [../playwright.config.js]
# @RELATION DEPENDS_ON -> [./tests/enterprise-clean-setup.e2e.js]
# @RELATION DEPENDS_ON -> [./tests/live-project-check.e2e.js]
# @RATIONALE Пустой образ (enterprise-clean bundle) требует полного цикла проверки: от сборки до
#   развёртывания и первичной настройки. Без этой orchestration QA не может гарантировать,
#   что образ ready-to-deliver. Разделение на 2 stage позволяет проверить как "чистую" установку
#   (fresh PostgreSQL, StartupEnvironmentWizard), так и "живой" проект с настроенными окружениями.
# @REJECTED Использование одного docker-compose файла для обоих стейджей — enterprise-clean требует
#   build из исходников + внешний PostgreSQL, а run.sh использует локальный dev compose.
# @DATA_CONTRACT Input: тег релиза (аргумент), .env.enterprise-clean.example, backend/.env
#   Output: dist/docker/*.tar.xz, dist/docker/manifest*.txt, playwright-report/

Enterprise Clean E2E Test Orchestrator — полный протокол тестирования пустого образа.

Протокол:
  Stage 1 — Empty Image Setup:
    1. Сборка enterprise-clean bundle (./build.sh bundle <tag>)
    2. Загрузка образов в Docker (xz -dc ... | docker load)
    3. Запуск PostgreSQL контейнера
    4. Развёртывание enterprise-clean стека
    5. Playwright: логин, StartupEnvironmentWizard, добавление ss-dev.bebesh.ru
    6. Остановка enterprise-clean стека

  Stage 2 — Live Project Verification:
    1. Запуск ./run.sh (backend + frontend)
    2. Playwright: логин (admin/admin123), LLM проверка дашборда, изменение настроек
    3. Остановка dev процессов

Аргументы:
  release-tag    Тег релиза (по умолчанию: e2e-test-<timestamp>)

Пример:
  ./e2e/run-enterprise-clean-e2e.sh v2.1.0
