fix(deps): preserve compatible linting #9

.ai/conventions/data.md

@@ -40,6 +40,11 @@ Authorization. Auth endpoints исключены из Bearer/retry middleware. R
 координируется single-flight; после `401` с `UNAUTHORIZED` возможен один retry.
 Не добавляй собственный refresh/retry loop в caller.
 
+Refresh, завершившийся `401`, очищает session. Сетевая ошибка и `5xx`
+(например, деплой backend) не доказывают конец session: она сохраняется,
+`unavailable` показывает retry-экран вместо login, а следующий `401` снова
+запускает refresh. Retry/backoff внутри refresh не добавляется.
+
 Cookie-writing requests упорядочены только в текущей вкладке. Cross-tab auth
 synchronization не требуется; допустим reload/re-login. Web Locks и отдельные
 token stores не добавляются.
