 Сквозное шифрование исходного клиента сохранено в коде как отдельная функция. Обычные сообщения сервер принимает и хранит в читаемом виде; HTTPS обеспечивает шифрование транспорта. Проверки не доказывают работу всех режимов сквозного шифрования и звонков с большим количеством участников.
 
+## Выпуск 1.0.7
+
+В [Аргусе](https://argus.kusoft.xyz/#app=ikar) опубликована [ИКАР 1.0.7, сборка 8](https://argus.kusoft.xyz/api/apps/ikar/releases/c3a069b6-1f5f-409a-a67e-59e6e0345ded/download). Пакет `ru.ikar.app` и подпись предыдущего выпуска сохранены; обновление доступно также через собственный сервер ИКАР.

+- Ответ на старое сообщение загружает нужное окно истории; новая навигация отменяет устаревший переход. Сервер проверяет участие в чате и видимость сообщения при запросе по ID.
+- Входящее «Поделиться» сохраняется в очереди Android. Следующий материал открывается после закрытия текущего экрана; файлы освобождаются после завершения использующих их загрузок.
+- Карточка файла показывает открытие и блокирует повторное нажатие до завершения действия.
+- Удаляемые сообщения скрываются сразу, доступны отмена и восстановление при ошибке сервера. Очередь удаления разделена по аккаунтам и чатам.
+- В настройках оформления доступна компактная нижняя панель с индикатором непрочитанных чатов; прежняя плавающая панель остаётся вариантом по умолчанию.
+- Ошибка отправки ICE-кандидата при обрыве сети обрабатывается и запускает переподключение. Завершение звонка отключает события старого соединения и безопасно освобождает ресурсы.
+
+Проверены 1206 тестов клиента (3 пропущены), 163 теста сервера и 16 сценариев рабочего HTTPS API. Передача данных через публичный TURN подтверждена по TCP и UDP после настройки проброса портов. Звонок через мобильную сеть на физическом устройстве в этом выпуске не проверялся.
+
+APK содержит актуальные Flutter-библиотеки всех трёх ABI и прежнюю подпись ИКАР. SHA-256: `db9bad659f93a9ddca0d484193f25c7430989e36385a2e0fd763976d873ee96a`. Сервер развёрнут в `releases/20261008-followups` с резервной копией базы и вложений; соседние сервисы сохранены. Проверки: `artifacts/apk-verification-1.0.7.json`, `artifacts/server-deployment-1.0.7.json`, `artifacts/argus-publication-1.0.7.json`, `artifacts/full-tests-1.0.7-fixed.log`.

Выпуск включает новую главную иконку, собственную тему, изменения жестов и видеоредактора, действия с расшифрованным текстом, работающую с сервером невидимость и меню расшифровки голосовых сообщений. Серверное исправление аватарок уже развёрнуто.

 Проверки: полный клиентский прогон — 1189 прошли, 3 пропущены; сервер — 150 прошли, без пропусков. Анализ `lib` и `test` не выявил ошибок и предупреждений, остались 42 информационных замечания стиля. Проверены выбор качества видео, сохранение темы, доступ к расшифрованному тексту, жесты, переключение невидимости, переподключение и сохранение публичной активности при обновлении схемы. Локальные отчёты: `artifacts/komet-full-flutter-tests.log`, `artifacts/komet-server-tests.log`, `artifacts/komet-implementation-analyze.log`.
 
-Рабочий API обновлён до `releases/20261007-komet`. Проверены совпадение SHA-256 серверной сборки, целостность рабочей базы и резервной копии, новая колонка публичной активности, `/health`, отсутствие перезапусков API и сохранность соседних контейнеров. Резервная копия перед обновлением: `/mnt/data/ikar_server/backups/ikar-20261007T191617Z.tar.gz`; предыдущий выпуск сохранён для отката. Через публичный HTTPS прошли 15 общих проверок API, 8 проверок невидимости и 5 проверок видео. Они охватывают регистрацию, доставку и историю, права доступа, файлы, речь на Pi, группы, каналы, реакции, опросы, отложенную отправку и сигнализацию звонков. Невидимая сессия получает сообщения и приглашения звонка, не меняя публичное время активности. Отчёты: `artifacts/deployment-komet.json`, `artifacts/ghost-live-verification.json`, `artifacts/live-smoke.json`, `artifacts/video-live-verification.json`.

 Главная иконка содержит только рисунок Икара без надписей. Размер рисунка — около 90% диаметра круглой области; адаптивный слой учитывает расширение Android с 72 до 108 dp. Исходный рисунок — `assets/ikar_mark.png`, основные ресурсы — `assets/ikar_icon.png` и `assets/ikar.png`. Пересоздание: `dart run tool/make_ikar_icons.dart`, затем `dart run flutter_launcher_icons`. Ресурсы основной иконки обновлены для Android, iOS, Windows и macOS; альтернативная иконка сохранена.

-Для звонков через разные NAT нужен проброс на роутере: 3478 TCP/UDP и 49160–49200 UDP на `192.168.0.185`. При проверке TURN работал через локальный адрес Pi; запросы на внешний адрес не получили ответа TURN. Публичная ретрансляция пока не подтверждена. Звонок с аудио/видео в эмуляторе прошёл через прямое WebRTC-соединение; это не доказывает работу через любую мобильную сеть.
