 - [x] **R01 · P1 · Долговременное хранение media-решений (A04/B23/A07).** Production Compose получил named `media_data` volume и отдельный root-only `media-init`: baseline из Git атомарно merge-ится только для новых assets, существующие решения/provenance не заменяются, volume передаётся API-пользователю. `backup.sh` сохраняет persistent manifest/assets в `media.tar.gz`, `restore.sh` восстанавливает их вместе с PostgreSQL и MinIO. Изолированный bootstrap подтвердил сохранение manifest после `--force-recreate` API; backup/restore drill подтвердил checksum и восстановление контрольного media-решения. Production secrets, внешнее backup-хранилище и серверный A07 acceptance-run остаются открытыми.
-- [ ] **R02 · P1 · Публикация выбранных media и защита от гонок (A04/B23).** Явные asset IDs, preview, версия manifest, lock и проверка файлов. Критерий: скрытые кандидаты не публикуются, устаревшее решение — конфликт, параллельные CLI/API не теряют изменения.
+- [x] **R02 · P1 · Публикация выбранных media и защита от гонок (A04/B23).** Admin API получил preview и явный набор SHA-256 asset IDs; publish больше не выбирает скрытые `upgrade_stored`, проверяет целостность выбранных файлов/вариантов, сверяет monotonic manifest version и возвращает `409` для устаревшей вкладки. Publish/rollback и CLI-совместимый путь сериализованы общим lock-файлом; решения пишутся атомарно и увеличивают версию. Regression покрывает выбор одного кандидата из двух и stale-version conflict; web admin передаёт ID и версию из заголовка manifest. Browser/production acceptance A04/A06/A07 остаётся отдельным gate.
 - [ ] **R03 · P1 · Идемпотентная отправка улова.** Сверять payload/срок ключа во всех ветках, включая IntegrityError и завершённый upload; обработать конкурентное создание Spot/Bait. Критерий: одинаковый повтор возвращает тот же результат, другой payload — 409, ожидаемые гонки не дают 500.
 - [ ] **R04 · P1 · Восстановление загрузки скриншота.** Атомарное одноразовое сохранение, повтор после потерянного ответа, очистка idempotency-cookie после восстановления. Критерий: нет лишних объектов, retry завершает форму и следующий новый улов отправляется.
 - [ ] **R05 · P1 · Полноценный каталог снастей (G06/G09).** Отдельная пагинация сборок/предметов, независимые ошибки, валидация URL-фильтров, empty search отдельно от незаполненного каталога. Критерий: 49+ сборок достижимы при 0 предметов, 422 не маскируется под 503. Убрать вложенные ссылки: карточка оборачивает DataPassport с source-link; проверить итоговый DOM и keyboard наполненных карточек.
