"""Проверка, что backend-адаптеры структурно удовлетворяют scraper_kit.contracts.
|
||
|
||
Двойная проверка:
|
||
1. Статическая — `_check_*` функции с аннотацией Protocol-типа. mypy проверит,
|
||
что каждый адаптер присваивается соответствующему Protocol'у (структурно).
|
||
2. Рантайм — `isinstance` против `@runtime_checkable` Protocol'ов (проверяет
|
||
наличие методов/атрибутов). Ловит рассинхрон имён без запуска mypy.
|
||
|
||
Границы контрактов зафиксированы для #2131 (шаг B); переключение скрапперов на
|
||
инжекцию — шаг C.
