+## Май 2026
+
+### Разработка
+
+#### 🐛 Исправлено
+
+**Web API покупателя — отсутствующие маршруты CustomerAPI (#241):**
+- Добавлен `POST /api/v1/customer/add` для быстрого обновления полей профиля (`first_name`, `last_name`, `email`, `phone`) через существующий `CustomerAPI.add()` и `CustomerUI.handleAdd()`.
+- Добавлен `POST /api/v1/customer/changeAddress` как совместимый endpoint для выбора сохранённого адреса в черновике заказа по `address_hash`.
+- Для быстрого обновления профиля добавлена whitelist-валидация и отдельное сообщение lexicon на `ru/en`; проверка уникальности email и сброс `email_verified_at` вынесены в общие методы контроллера профиля.
