ФУНКЦИИ - МЕЖПРОЕКТНАЯ КОММУНИКАЦИЯ: зеркалирование комментариев, вложений и активности внешнего контура

 - для закрытого внешнего запроса доступны source-side действия `Принять` и `Отклонить`
 - `Принять` фиксирует решение источника в bridge metadata и помечает запрос как принятый во внутренний контур
 - `Отклонить` возвращает target issue в default-state целевого проекта и переносит source-side карточку обратно в список `Открытые`
+- source-side readonly карточка зеркалит актуальные комментарии, вложения и activity целевой задачи
+- вложения доступны через proxy download endpoint без прямого membership в target project
+- detail карточка source-only пользователя обновляется polling-ом и подтягивает новые комментарии без ручной перезагрузки
 
 Что остается:
-- зеркалирование комментариев
+- зеркалирование inline-файлов из комментариев и описания, а не только issue attachments
-- зеркалирование файлов
+- двусторонняя работа с комментариями из source-side карточки
-- зеркалирование activity stream и обновлений описания
 - комментарий причины отклонения и ответ обратно во внешний контур
