+# Личные плейлисты
+
+Плейлисты хранятся в PostgreSQL и доступны владельцу на вебе и в React Native-клиенте. В вебе раздел находится в коллекции; на узком экране — в меню «Ещё». В мобильном клиенте — кнопка «Плейлисты» в коллекции.
+
+Можно создать плейлист, изменить название и описание, добавить трек из поиска, альбома или коллекции, убрать трек и переместить его выше/ниже. В вебе можно добавить целый альбом. Один трек встречается в плейлисте один раз: повторное добавление не создаёт дубль. Воспроизведение доступно в сохранённом или случайном порядке; недоступные треки остаются видимыми, но пропускаются при запуске всего плейлиста. Удаление плейлиста требует подтверждения и не удаляет музыку из каталога.
+
+## API
+
+- `GET /api/v1/me/playlists` — сводки личных плейлистов, последние изменённые первыми.
+- `POST /api/v1/me/playlists` — создание: `name`, `description`, `track_ids`.
+- `GET /api/v1/me/playlists/{id}` — метаданные и упорядоченные треки с персональными реакциями и подписанными ссылками.
+- `PUT /api/v1/me/playlists/{id}` — атомарная замена метаданных и порядка треков; дополнительно требуется `revision` из прочитанного плейлиста.
+- `DELETE /api/v1/me/playlists/{id}` — удаление.
+
+Все операции требуют авторизации. Чужой и отсутствующий плейлист возвращают одинаковый `404`. Изменения блокируют строку плейлиста в транзакции; устаревшая версия возвращает `409 playlist.conflict`. Редактор сохраняет исходную версию до закрытия, даже если фоновый запрос получил новую. Ошибка трека откатывает изменение целиком. Ввод ограничен 120 символами названия, 2000 символами описания и 2000 уникальными треками.
+
+Миграция `00013_playlists.sql` создаёт таблицы `playlists`, `playlist_tracks` и индексы. Удаление пользователя очищает его плейлисты; удаление трека из каталога очищает его членство. Таблицы не затрагивают музыкальные файлы.
+
+Плейлисты личные; публичные ссылки, совместное редактирование и загрузка пользовательских обложек не входят в эту реализацию. Карточки имеют градиентную обложку, страница использует обложку первого трека. Контекст воспроизведения — `collection` с UUID и названием плейлиста.
+
+## Проверки
+
+- `pnpm --filter @pipu/web test src/App.test.tsx -t playlists`
+- `pnpm --filter @pipu/web test:e2e e2e/playlists.spec.ts`
+- `pnpm --filter @pipu/web build`
+- `pnpm --filter @pipu/mobile typecheck`
+- В `services/api`: `go test ./internal/playback ./internal/server`
+- С отдельной тестовой PostgreSQL/pgvector: `TEST_DATABASE_URL=… go test -tags integration ./internal/playback -run TestPlaylistPersistenceAndIsolation -v`. Проверяет сохранение порядка, изоляцию владельцев, откат при несуществующем треке, конфликт конкурентных записей и каскадное удаление членства.
