 ### 3. 🛡️ Дедупликация слов и защита от повторного добавления (Reader + API)
-- [ ] **Проверка дубликатов на бэкенде (`POST /api/cards`)**:
-  - Проверять наличие слова для пользователя без учёта регистра: `lower(trim(term))`.
-  - При попытке повторного добавления: не создавать дубликат-клон, а дополнять контекстное предложение (если в новой цитате другой контекст) и объединять теги книги (`tags`), возвращая существующую карточку со статусом `already_exists`.
-- [ ] **Индикация в читалке (Reader Popup)**:
-  - При клике на слово проверять, есть ли уже `cleanTerm` в словаре пользователя.
-  - Если слово уже сохранено: показывать зелёный бейдж `✓ В словаре` вместо активной кнопки `+ В словарь` (предотвращая случайные повторные клики).
-  - Предоставить кнопку «Добавить контекст» для привязки новой цитаты к существующей карточке.
-- [ ] **Индекс целостности в SQLite**:
-  - Добавить `CREATE INDEX IF NOT EXISTS idx_vocab_user_term_nocase ON vocabulary_cards(user_id, term COLLATE NOCASE);` для мгновенного поиска за $O(\log N)$.
-- [ ] **Слияние существующих дубликатов в базе**:
-  - Написать безопасную миграцию/скрипт, объединяющий накопившиеся дубликаты (например, `admired`, `suddenly`/`Suddenly` у пользователя `kopri`), объединяя контексты предложений и сохраняя историю повторений SRS.
+- [x] **Проверка дубликатов на бэкенде (`POST /api/cards`)**:
+  - Проверка слова без учёта регистра `lower(trim(term))`.
+  - При повторном добавлении не создаётся дубликат, а дополняется контекстное предложение и объединяются теги, возвращается `already_exists: True`.
+- [x] **Индикация в читалке и карточке поиска**:
+  - В читалке при клике на слово и в карточке поиска выводится бейдж `⭐ В библиотеке`.
+  - Кнопка «+ В словарь» заменяется на бейдж `⭐ Слово уже в библиотеке` с опциональной кнопкой `+ Добавить эту цитату к карточке`.
+- [x] **Индекс целостности в SQLite**:
+  - Создан `UNIQUE INDEX idx_vocab_user_term_nocase ON vocabulary_cards(user_id, term COLLATE NOCASE);` гарантирующий отсутствие дубликатов на уровне движка БД за $O(\log N)$.
+- [x] **Слияние существующих дубликатов в базе**:
+  - Объединены дубликаты `admired` (ID 5 и ID 7) и `suddenly`/`Suddenly` (ID 2 и ID 9) с объединением контекстных предложений, слиянием тегов и сохранением прогресса SRS.
