 # MusicBridge iOS — план

-Обновлено: 2026-09-13. Пользователь разрешил начать нативное iOS-приложение.
+Обновлено: 2026-09-14. Пользователь разрешил начать нативное iOS-приложение.
 Репозиторий: `C:/Users/areso/iOS MusicBridge`; origin — dev.yukinoki.ru/musicbridge/ios.
 Windows-агент — соседний проект `C:/Users/areso/MusicBridge/MusicBridge.Agent`.

-## Правила проекта
+## Системный пульт 0.7.0 (8) — текущий этап
+
+- [x] Реализация NowPlaying RemoteMediaSession и отдельного ExtensionKit target для iOS 27.
+- [x] Кнопка включения/выключения в приложении; музыка продолжает играть на ПК.
+- [x] Метаданные, обложка, play/pause, предыдущий/следующий трек, перемотка, громкость ПК.
+- [x] Перед командой проверяются свежие capabilities и действующее сопряжение; команды не повторяются автоматически.
+- [x] Токен хранится в общем Keychain, не передаётся в атрибутах системной сессии.
+- [x] Перемотка переводится из позиции относительно трека в диапазон Windows API.
+- [x] Выключение и удаление сопряжения удаляют доступ расширения; возврат запоздавшего restore не восстанавливает сессию.
+- [x] Итоговый `91e305a`: [Actions 34785082289](https://github.com/polskikh13/musicbridgeios/actions/runs/34785082289), Xcode 27, 36 XCTest без отказов, успешный Release archive. Первая попытка 34783380221 выявила Double/Float и исправлена.
+- [ ] Установка с подписью обоих расширений и общим Keychain; проверка на физическом iPhone.
+- [ ] Пункт управления: кнопки, перемотка, громкость; блокировка телефона, сон ПК, отзыв токена, повторная подпись.
+
+IPA скачана в `build/iPhone-0.7.0/MusicBridge-iPhone.ipa` (без подписи).
+Локально проверены ZIP, ARM64 iPhoneOS всех трёх исполняемых файлов,
+совпадение версий, ExtensionKit extension point и общий Keychain suffix.
+SHA-256: `a84e146a5259c0c7250dab829f2eb07093f33d5e212ff1e1880f6c3fd29d65ee`.
+Логи тестов находятся в `build/iPhone-0.7.0/tests`, снимки — в `preview`.
+Просмотрены светлый плеер и дополнительный iPhone: кнопка пульта видна снизу,
+пояснения доступны прокруткой. Системная карточка NowPlaying на этих снимках
+не проверялась: для запуска нужен подписанный общий Keychain.
+
+**Ограничение iloader:** проверен официальный исходник `nab138/isideload`, ветка
+`apple-codesign-quick`, commit `f6a4d5dba717d72fc2af63eaba26b27ba44116be`, который использует текущий iloader.
+`isideload/src/sideload/bundle.rs` обнаруживает расширения только в `PlugIns`,
+а NowPlaying размещается в `Extensions`. `sign.rs` берёт entitlements из profile,
+добавление shared Keychain реализовано для отдельных SpecialApp, не для MusicBridge.
+Поэтому обычную установку 0.7.0 через iloader нельзя считать поддержанной.
+Не переносить ExtensionKit в PlugIns наугад и не передавать токен через публичные атрибуты.
+Следующий этап установки: совместимый подписыватель или доработка iloader для
+ExtensionKit и общего Keychain с реальными provisioning profiles. Xcode signing
+всех трёх targets — вариант при наличии совместимого Mac и профилей; разрешение
+нового extension point бесплатной командой ещё не подтверждено на устройстве.
+
+2026-09-14 пользователь попробовал установку 0.7.0: IXErrorDomain 2/8,
+родитель стал `ru.yukinoki.musicbridge.<TeamID>`, а remote остался
+`ru.yukinoki.musicbridge.remote`. Это подтверждает пропуск Extensions при переименовании.
+Дополнительно библиотека apple-codesign-quick также обходила только Frameworks/PlugIns.
+В `tools/iloader` добавлены патчи обоих уровней и воспроизводимая подготовка
+закреплённых upstream revisions. Отдельный ручной workflow `iloader-compat.yml`
+собирает portable Windows GUI; исходное приложение iloader на ПК не заменяется.
+Патч сохраняет публичные Bundle ID приложения до подписи, затем iloader сам
+применяет TeamID ко всем расширениям и получает для них настоящие Apple profiles.
+Shared Keychain для MusicBridge добавляется только при разрешении в profile.
+- [x] Проверено чистое применение патчей к закреплённым исходникам.
+- [ ] Rust-тесты на переименование/обнаружение ExtensionKit, вложенную подпись и Keychain.
+- [ ] Готовый portable EXE и повторная установка исходной IPA 0.7.0 через него.
+- [ ] Подтвердить регистрацию NowPlaying и общий Keychain на iPhone.
+
+Без APNs расширение читает ПК при команде; открытое приложение обновляет сессию
+при смене трека/статуса и периодически. Смена трека на самом ПК при приостановленном
+приложении не гарантирует автоматического обновления карточки. Фиктивное аудио не используется.
+
+## Инфраструктура — текущее состояние
+
+- SSH к macOS проверен: `aresov@10.67.67.28`, macOS 26.6.2, x86_64,
+  около 459 ГБ свободно. Xcode не установлен. Локальный отдельный ключ:
+  `C:/Users/areso/.ssh/musicbridge_macos_ed25519` (закрытый ключ не включать в репо).
+  Использовать `C:/Windows/System32/OpenSSH/ssh.exe` с `-F NUL`,
+  `-o ProxyCommand=none -o ProxyJump=none -o IdentitiesOnly=yes` и этим ключом;
+  другая установленная версия ssh не подключалась. Host key сохранён в known_hosts.
+- Xcode 27 требует Apple Silicon; эта Intel-виртуалка не подходит для SDK 27.
+  CI переведён на GitHub-hosted `xcode-27`: Xcode 27.0 (27A5252f), Swift 6.4, SDK iOS 27.0.
+  [Actions 34764552877](https://github.com/polskikh13/musicbridgeios/actions/runs/34764552877)
+  для `1e14bf7`: 32 XCTest, 0 отказов, успешный Release archive.
+  IPA: `build/iPhone-0.6.0-xcode27/MusicBridge-iPhone.ipa`; проверены SDK 27, ARM64
+  приложения/расширения и структура пакета. Предпросмотр карточки просмотрен.
+  Версия осталась 0.6.0 (7); новые функции в пересборке не добавлены.
+  Просроченный тестовый сертификат создаётся с явными датами через
+  cryptography==46.0.3 в отдельном venv, поскольку новый OpenSSL отвергает -days -1.
+- Пользователь подтвердил бесплатный Apple Account через iloader.
+  Фоновая доставка APNs заблокирована отсутствием Push Notifications capability
+  и соответствующей подписи. Платная Developer Program, App ID, ключ APNs и
+  provisioning profile пока отсутствуют; не обещать работу push после простой
+  смены Xcode. После появления доступа нужны регистрация токенов, отправитель
+  обновлений с Windows/сервера и тестирование доставки на физическом iPhone.

+
+GitHub Actions использует Apple Silicon runner `xcode-27` с проверкой версии Xcode.
+SSH к локальной macOS-виртуалке настроен, однако она x86_64, без Xcode и не может
+запускать Xcode 27. Для SDK 27 используется GitHub Actions.
+
+Тестовый TLS-сервер требует `cryptography==46.0.3`; CI устанавливает пакет
+в отдельное Python-окружение. Это зависимость тестов, не приложения.
+
+Пользователь использует бесплатный Apple Account. APNs требует Push Notifications
+capability и подписи с соответствующим provisioning profile, недоступных Personal Team.
+Поэтому автоматическая фоновая доставка ещё не подключена. Команды Live Activity
+выполняют запросы при нажатии; смена трека на ПК при приостановленном приложении
+не обновляет карточку без запроса или push.

+
+Патчи хранятся в репозитории MusicBridge в tools/iloader. Workflow
+iloader-compat.yml запускается вручную, не использует Apple Account/сертификаты.
+Apple-авторизация и подпись происходят только локально на компьютере пользователя.
+
+Исправления: обнаружение Extensions вместе с PlugIns, переименование и получение
+профиля каждого расширения, вложенная подпись ExtensionKit и общий Keychain для
+MusicBridge только в пределах разрешений настоящего provisioning profile Apple.
+Регрессионные Rust-тесты проверяют обе папки расширений, сохранение новых Bundle ID,
+обработку вложенной подписи и отказ при недопустимой Keychain group.
+
+Использование после успешной сборки:
+1. Закрыть обычный iloader. Удалять его и установленный MusicBridge не требуется.
+2. Запустить iloader-musicbridge.exe. Заголовок окна содержит compatibility build.
+3. Использовать прежний Apple Account; выбрать исходную MusicBridge 0.7.0 IPA.
+4. Подписать и установить заново. Все расширения нужно сохранить.
+5. Проверить обычное подключение, затем кнопку системного пульта и Пункт управления.
+
+Вариант сохраняет идентификатор/хранилище обычного iloader для локального входа,
+поэтому одновременно запускать обе версии не нужно. Обновления из upstream в
+этой сборке отключены. Совместимость нового extension point с бесплатным профилем
+Apple окончательно подтверждается только установкой на устройстве.
