+    "summary": "AssistantService теперь принимает ForecastService через __init__ (раньше создавал new ForecastService() внутри analyze/advice). В infrastructure/cli/main.py добавлен _build_services() — composition root, собирающий граф зависимостей: CurrencyConverter, ForecastService, ScenarioService, AssistantService. Все CLI-команды (forecast, scenario, whatif, compare, analyze) используют _build_services(model) вместо прямого создания сервисов. test_ai.py обновлён.",
