 ## Шаг 2. Группы и студенты
 
-**Группы → Импорт** — загрузите `.xls`/`.xlsx`/`.csv` со списком группы
-(столбцы: «Студенческий номер», «Фамилия Имя Отчество», «Основа обучения»).
-Название группы берётся из файла или указывается при импорте. Логином студента
-становится студенческий номер, пароль генерируется (временный, с обязательной
-сменой при первом входе).
+**Группы → Импорт** — загрузите `.xls`/`.xlsx`/`.csv` со списком группы.
+Обязательные столбцы:
+
+```text
+поток | курс | номер | степень | год набора | ФИО | № | база
+```
+
+Все строки файла должны относиться к одной группе. Группа создаётся по полям
+(имя собирается автоматически, например `ПИ-11БО`). Логином студента становится
+номер (`№`), пароль генерируется (временный, с обязательной сменой при первом
+входе). Ключ слияния — `student_no`: повторный импорт обновляет студента, а не
+дублирует.
+
+Импорт атомарный: при ошибке в любой строке данные не меняются, а в интерфейсе
+показывается отчёт с номерами строк.
 
 Дальше по каждому студенту при необходимости:
 * **«Сбросить пароль»** — выдать новый временный пароль;
 * **«Добавить существующего»** — перевести студента из другой группы;
-* **«Отчислить из группы»** — убрать из группы (аккаунт и данные сохраняются).
+* **«Отчислить из группы»** — убрать из группы, студент получает статус
+  «отчислен»; аккаунт, сдачи и оценки сохраняются.
 
 Выгрузить логины: **«Логины XLSX» / «CSV»**.

+# 11. Отчёт этапа 1: identity
+
+**Дата:** 2026-10-23.
+**Статус:** этап 1 выполнен; этап 2 (academic) — следующий.
+
+## 1. Что сделано
+
+### Роли и аккаунты
+
+- Добавлена роль `TEACHER` в `LmsRole`; БД уже допускает её миграцией `V4`.
+- `Account` получил `status` (`ACTIVE/ARCHIVED`) и `archivedAt`.
+- Вход запрещён для архивных аккаунтов и студентов в статусах
+  `EXPELLED/GRADUATED/ARCHIVED`.
+
+### Группы-когорты
+
+- `GroupEntity`: `stream`, `course`, `number`, `degree`, `enrollmentYear`,
+  `status` (`ACTIVE/GRADUATED/ARCHIVED`).
+- `name` больше не уникально; уникальность — по кортежу когорты.
+- `GroupNameParser` разбирает `ПИ-11БО`, `ИВТ-ТОП-12БО` и т.п.
+- `GroupCohortResolver` валидирует степень, курс, номер и год набора,
+  вычисляет год набора по умолчанию.
+- Создание группы через админку — по полям, имя собирается автоматически.
+
+### Студенты и история
+
+- `Student`: `status` и `enrollmentYear`.
+- `MembershipHistory`: `ENROLL`, `TRANSFER`, `IMPORT`, `EXPELL` и остальные
+  действия; записи создаются при зачислении, переводе, импорте и отчислении.
+- При отчислении студент получает `EXPELLED`, аккаунт и данные сохраняются.
+- Повторное зачисление возвращает `ACTIVE` и пишет `TRANSFER`.
+
+### Импорт Excel/CSV v2
+
+Шаблон:
+
+```text
+поток | курс | номер | степень | год набора | ФИО | № | база
+```
+
+- Поддерживаются `.xls`, `.xlsx`, `.csv`, разделители `;`, `,`, tab.
+- ФИО можно одной колонкой или отдельными `Фамилия/Имя/Отчество`.
+- Все строки должны быть одной группой.
+- Проверяются степень, диапазон курса, год набора, пустые поля,
+  дубли `№` внутри файла.
+- Импорт атомарный: при ошибках данные не меняются, возвращается отчёт
+  с номерами строк.
+- Ключ слияния — `student_no`; группа ищется по кортежу, при отсутствии
+  создаётся.
+- Новые студенты получают временный пароль; пароли показываются один раз.
+
+### UI
+
+- Страница групп: год набора, статус, создание по полям, описание нового импорта.
+- Страница группы: год набора, статус группы, статус студента.
+- Страница пользователей: статус студента.
+- При ошибке импорта показывается таблица «строка — ошибка».
+
+## 2. Тесты
+
+Добавлены:
+
+- `GroupNameParserTest` — разбор имени, диапазоны курсов;
+- `StudentImportParserTest` — валидный шаблон, дубли, разные группы,
+  недопустимый курс, неизвестная шапка;
+- `GroupServiceIntegrationTest` — создание когорты, дубликат, импорт,
+  атомарность ошибок, перевод, отчисление, запрет входа после отчисления.
+
+Проверки:
+
+- `./gradlew :services:identity-service:test :web:test` — успешно;
+- `ktlintCheck` и `detekt` для identity/web — успешно.
+
+## 3. Ограничения этапа
+
+- Импорт поддерживает одну группу на файл; мультигрупповой файл — позже.
+- Ведущие нули номера группы нормализуются к числу (`01` → `1`);
+  имя строится из числового номера. Если нужны разные `ПИ-11БО` и `ПИ-101БО`
+  как отдельные когорты, потребуется хранить номер строкой.
+- Роль `TEACHER` уже есть в домене, но кабинет преподавателя и назначения
+  на курс — этапы 2–3.
+- `ACADEMIC_LEAVE` пока может входить; режим «только чтение» — этап 3.
+- Отчисление пока простое; причины, подтверждение и аудит — этап 4.
+- Старый формат импорта (только студенческие колонки) больше не поддерживается.
+
+## 4. Следующий этап
+
+Этап 2 — academic:
+
+- курсы, `course_teachers`, `course_groups`;
+- `course_no` и `/learn/course/{course_no}/...`;
+- `labs.course_id` и перенос лаб в курс C;
+- `chapters.course_id/audience`, перенос материалов;
+- активы и копирование лабораторных;
+- админ-UI курсов.
