+## Review Checklist
+
+При проверке кода (Code Review) обязательно убедитесь в соблюдении следующих пунктов:
+
+- [ ] Соблюдено Dependency Rule: зависимости направлены внутрь модулей.
+- [ ] Все внешние I/O и межмодульные взаимодействия закрыты протоколами (Application Ports).
+- [ ] Состояние инкапсулировано в `actor` или защищено Swift 6 Concurrency.
+- [ ] Отсутствуют `Task.detached` без явного обоснования и управления жизненным циклом.
+- [ ] Все публичные и семантически значимые декларации снабжены русским DocC.
+- [ ] Новые TODO/FIXME содержат ссылку на issue.
+- [ ] Не нарушен Local-First Data Contract: сырые данные не сохраняются, секреты в Keychain.
+- [ ] Код соответствует нормативным паттернам из Architecture Playbook.
