+# Правила разработки
+
+## Обязательные требования пользователя
+
+- Использовать C#, .NET 10 и PostgreSQL. Приложение и БД запускаются в отдельных Docker-контейнерах в общей сети.
+- Писать небольшие, читаемые классы с одной ясной ответственностью. Не создавать сложные объёмные классы и абстракции без практической необходимости.
+- Не использовать `record` и `record struct`. Модели и DTO — обычные классы со свойствами `get; set;`.
+- Использовать привычные типы данных. Не вводить экзотические типы и конструкции без обсуждения.
+- Соблюдать инверсию зависимостей. Domain не зависит от инфраструктуры и UI; Application не зависит от Infrastructure или Web.
+- Не зашивать настраиваемые значения в код. Значения по умолчанию и параметры поведения выносить в `appsettings.json`, секреты — в переменные окружения. Поддерживать переопределение через `.env` и Docker Compose.
+- Не хранить пароли, строки подключения с секретами или реальные клиентские данные в репозитории.
+- При неясности в архитектуре или устройстве конкретного класса остановиться и задать пользователю вопрос до реализации спорного решения.
+- Не добавлять функциональность вне согласованного объёма.
+- Не проверять результат скриншотами, пока пользователь явно не попросит об этом. Для проверки UI использовать состояние страницы и функциональные проверки без снимков.
+
+## Согласованный объём первой версии
+
+- Рабочее место одного тренера с возможностью расширения на нескольких.
+- Вход по логину и паролю, без регистрации и клиентского кабинета.
+- Клиенты и библиотека упражнений; добавление упражнений также вручную.
+- Группы содержат независимые упражнения. Удаление группы удаляет её упражнения из библиотеки; тренировки сохраняют свои снимки. Корзина внутри группы удаляет упражнение полностью из библиотеки.
+- Drag and drop переносит упражнение в другую группу или в «Без группы». Добавление упражнения из другой группы создаёт независимую копию.
+- В конфигураторе — адаптивный выпадающий список с текстовым поиском и фильтром по группе. Двойной клик сразу применяет выбранное упражнение.
+- Персональная месячная программа: недели, тренировки, упорядоченные блоки.
+- Упражнение: общие количество подходов, текстовые повторения и вес; разминка и примечание текстом; процент от максимума вручную; ссылка на видео и флаг камеры.
+- Сеты удалены из функционала. Один блок содержит ровно одно упражнение.
+- Отдых в минутах (дробные значения допустимы). Общий отдых: сумма количества подходов × отдых, включая паузу после последнего подхода. Время тренировки вводится вручную.
+- Перестановка блоков, тренировок и недель с автоматической перенумерацией.
+- История программ клиента и независимое копирование для следующего месяца.
+- Экспорт PDF: альбомная таблица, цветные заголовки недель и тренировок, кликабельные ссылки. Видео не загружаем и не принимаем.
+- Приоритет — компьютер. Полноценная адаптация под iPhone 15 — следующий этап.
+
+## Работа с проектом
+
+- После изменений выполнять сборку и проверки, соответствующие изменению.
+- Поддерживать README и `.env.example` в соответствии с реальной конфигурацией.
+- Не заявлять о проверке Docker, БД, PDF или UI, если соответствующая проверка не выполнена.

+# Training Planner
+
+Рабочее место тренера на C# / .NET 10: персональные программы на месяц, упражнения, история клиента и выгрузка PDF.
+
+## Возможности
+
+- Вход по логину и паролю без регистрации; первый аккаунт создаётся при первом запуске.
+- Карточки клиентов: имя, цель, режим тренировок, состояние здоровья, отдельные заметки тренера и история программ. Корзина в карточке удаляет клиента вместе с его программами после подтверждения. У каждой программы есть отдельная корзина с подтверждением удаления.
+- Библиотека упражнений с видеоссылками, независимыми группами и ручным добавлением в программу.
+- «Импорт из таблицы»: вставка двух столбцов из Excel/Google Sheets без заголовков (название и ссылка) в модальном окне. Количество строк растёт автоматически; ячейки можно исправить, строки добавить или удалить. Ссылка необязательна. Можно выбрать существующую группу, создать новую или оставить без группы. Пустые строки пропускаются, одинаковые названия создают отдельные упражнения. При ошибке импорт целиком отклоняется, данные остаются для исправления.
+- Создание, переименование и удаление групп вместе с их упражнениями. Корзина упражнения удаляет его из библиотеки; составленные тренировки не меняются.
+- Перенос упражнения на группу или «Без группы» перетаскиванием. Добавление из другой группы создаёт независимую копию.
+- Поиск в конфигураторе: адаптивный выпадающий список с фильтром названия и группы. Двойной клик или Enter сразу добавляет упражнение; одиночный клик выбирает его для кнопки «Добавить». Точное совпадение и начало названия выше остальных; регистр и «ё/е» не мешают поиску.
+- Удаление из библиотеки через корзину с подтверждением; упражнения в ранее составленных программах сохраняются.
+- Недели, тренировки и перемещаемые блоки. Перетаскивание за маркер или кнопки вверх/вниз.
+- Общие подходы, текстовые повторения и вес; текстовые разминка и примечание; процент от максимума вручную.
+- Отдых в минутах. Итог — количество подходов × отдых, включая последний подход. Время тренировки задаётся вручную.
+- Копирование блоков, тренировок, недель и всей программы. Каждое упражнение — отдельный блок; сетов нет.
+- Перетаскивание недель с автоматической перенумерацией и сохранением порядка.
+- Перетаскивание тренировок внутри недели с указателем вставки, перенумерацией и сохранением выбранной тренировки.
+- Удаление выбранной недели вместе с тренировками после подтверждения; в программе остаётся минимум одна неделя.
+- Удаление тренировки через иконку корзины с подтверждением; после удаления последней тренировки неделю можно заполнить заново.
+- Автосохранение, ручное сохранение, отмена последнего удаления блока в течение 10 секунд только в исходной тренировке (настройка `.env`: `Planner__UndoDeleteDurationSeconds`) и защита от перезаписи из другой вкладки.
+- В начале PDF — таблица с именем, целью, режимом тренировок и состоянием здоровья клиента. Заметки тренера не экспортируются.
+- Альбомный PDF: одна непрерывная таблица на неделю, цветные разделители тренировок с отдельными итогами, одна строка на упражнение, кликабельные ссылки и значки камеры. Ширина таблицы — 27,5 см; PNG камеры встроен в сборку, выровнен по центру ячейки. Размер иконки задаётся `Pdf__CameraSizePoints`.
+
+Интерфейс первой версии рассчитан на компьютер. Полная адаптация под iPhone 15 отложена. Клиентского кабинета, загрузки видео, регистрации и работы без интернета нет. Blazor Interactive Server требует соединения с сервером.
+
+## Запуск в Docker
+
+Нужны Docker Engine/Desktop и Docker Compose.
+
+```sh
+cp .env.example .env
+# Заполните POSTGRES_PASSWORD, BOOTSTRAP_TRAINER_USERNAME и BOOTSTRAP_TRAINER_PASSWORD.
+docker compose up --build -d
+```
+
+По умолчанию приложение доступно на `http://localhost:8080`; порт меняется через `APP_PORT`. Пароль тренера должен соответствовать настройкам Identity: по умолчанию минимум 12 символов, цифра, строчная/прописная буква и спецсимвол.
+
+Миграции применяются при запуске, затем создаётся первый тренер. Если аккаунт уже есть, переменные BootstrapTrainer его не изменяют и не сбрасывают пароль.
+
+Два контейнера находятся в общей сети. PostgreSQL 18 не публикует порт на хост. Данные БД и ключи cookie сохраняются в именованных volumes. `docker compose down` сохраняет их; не используйте `down -v`, если данные нужны.
+
+## Конфигурация
+
+`appsettings.json` задаёт значения по умолчанию. Docker Compose читает `.env`; `env_file` передаёт его содержимое контейнеру. Сам .NET автоматически `.env` не читает.
+
+| Переменная в .env | Назначение |
+|---|---|
+| `APP_BIND_ADDRESS`, `APP_PORT` | Адрес и порт приложения на хосте |
+| `POSTGRES_IMAGE`, `POSTGRES_DB`, `POSTGRES_USER`, `POSTGRES_PASSWORD` | База данных |
+| `BOOTSTRAP_TRAINER_USERNAME`, `BOOTSTRAP_TRAINER_PASSWORD` | Первый тренер |
+| `PLANNER_DEFAULT_WEEK_COUNT` | Число недель новой программы |
+| `PLANNER_DEFAULT_SETS_COUNT` | Начальное число подходов |
+| `PLANNER_DEFAULT_REPETITIONS` | Начальное значение повторений |
+| `PLANNER_DEFAULT_REST_MINUTES` | Начальный отдых в минутах (например, 1.5) |
+| `PLANNER_DEFAULT_WORKOUT_NAME` | Основа названия новой тренировки |
+| `PLANNER_DEFAULT_WORKOUT_DURATION` | Время новой тренировки, по умолчанию `1 час` |
+| `PLANNER_DEFAULT_INTENSITY_PERCENT` | Процент нового упражнения, по умолчанию `80` |
+| `PLANNER_AUTOSAVE_DELAY_MS` | Задержка автосохранения |
+| `REQUIRE_HTTPS` | Защищённые cookie и перенаправление на HTTPS |
+| `REVERSE_PROXY_IP` | Доверенный адрес обратного прокси |
+| `COOKIE_HOURS`, `AUTH_REVALIDATION_MINUTES` | Срок cookie и повторная проверка авторизации |
+| `DATABASE_INITIALIZE_ON_STARTUP` | Применение миграций и создание первого тренера |
+
+Другие секции можно переопределять через стандартные имена .NET с `__`, например `Pdf__FontSize=11`, `Pdf__ColumnWidthsCentimeters__0=7`, `Identity__Password__RequiredLength=16`. Для настроек, явно перечисленных в Compose, используйте переменные из таблицы: значения секции `environment` имеют приоритет над `env_file`.
+
+Лимиты импорта: `ExerciseImport__MaxRows=1000`, `ExerciseImport__MaxClipboardCharacters=100000`. Размер сообщения Blazor задаётся `InteractiveServer__MaximumReceiveMessageBytes=1048576`; при увеличении лимита текста учитывайте запас для UTF-8 и JSON. Все три параметра переопределяются через `.env`.
+
+Шрифты PDF по умолчанию устанавливаются внутрь образа. Если задаёте другие пути, файлы должны быть доступны внутри контейнера. Не храните секреты в Git; `.env` исключён из Git и Docker build context.
+
+## Публичное развёртывание
+
+Локальная `.env.example` использует HTTP и привязку к loopback. Для публичного сервера настройте TLS на обратном прокси, `REQUIRE_HTTPS=true` и доверенный `REVERSE_PROXY_IP`. Прокси должен передавать `X-Forwarded-Proto`, поддерживать WebSocket для Blazor и иметь доступ к выбранному адресу приложения. По умолчанию appsettings требует HTTPS.
+
+Регистрации нет. Сервер проверяет принадлежность клиентов, упражнений и программ текущему тренеру. Повторные неудачные входы блокируются настройками Identity. Формы входа/выхода защищены antiforgery.
+
+Резервная копия БД:
+
+```sh
+docker compose exec -T database sh -c 'pg_dump -U "$POSTGRES_USER" "$POSTGRES_DB"' > backup.sql
+```
+
+Храните резервные копии отдельно от сервера. Настройку расписания и хранения резервных копий нужно выполнить на целевом сервере.
+
+## Локальная разработка
+
+Нужны .NET SDK 10 и доступный PostgreSQL. Передайте `ConnectionStrings__TrainingDatabase`, `BootstrapTrainer__UserName`, `BootstrapTrainer__Password` и пути `Pdf__FontPath`, `Pdf__BoldFontPath` к TTF-шрифтам с кириллицей. В Linux-контейнере пути настроены автоматически. Для HTTP-разработки задайте `ASPNETCORE_ENVIRONMENT=Development`.
+
+```sh
+dotnet restore TrainingPlanner.slnx
+dotnet build TrainingPlanner.slnx
+dotnet test tests/TrainingPlanner.Tests
+dotnet run --project src/TrainingPlanner.Web
+```
+
+Для новой миграции:
+
+```sh
+dotnet tool restore
+dotnet ef migrations add MigrationName --project src/TrainingPlanner.Web --output-dir Data/Migrations
+```
+
+## Структура
+
+- Domain: небольшие предметные классы со свойствами `get; set;`.
+- Application: сценарии редактирования, валидация, копирование и контракты.
+- Infrastructure: PostgreSQL, Identity, PDF.
+- Web: Blazor-компоненты, HTTP-страницы авторизации и экспорта, конфигурация.
+- Tests: проверки копирования параметров, порядка, валидации и расчёта отдыха.
+
+Подробности — `docs/architecture.md`. Обязательные правила разработки — `AGENTS.md`.
+
+### Обновление старых программ
+
+Перед применением миграции ExercisePrescription сделайте резервную копию БД. Общие вес и повторения берутся из первого подхода, старые сеты разделяются на одиночные упражнения, отдых переводится из секунд в минуты. Разные веса последующих подходов больше не используются. Для возврата к прежней модели нужны резервная копия и прежняя версия приложения. Переменные `PLANNER_DEFAULT_REST_SECONDS` и `PLANNER_DEFAULT_ROUNDS` заменены на `PLANNER_DEFAULT_REST_MINUTES` и `PLANNER_DEFAULT_SETS_COUNT`.

+# Архитектура и границы первой версии
+
+## Стек
+
+.NET 10, ASP.NET Core, Blazor, EF Core, PostgreSQL. Один процесс приложения и отдельный контейнер БД. Без микросервисов.
+
+## Зависимости
+
+- Domain: простые предметные классы, без зависимостей от UI и хранилища.
+- Application → Domain: прикладные сценарии и контракты хранилища.
+- Infrastructure → Application: EF Core, PostgreSQL, авторизация и внешние сервисы.
+- Web → Application + Infrastructure: интерфейс и регистрация зависимостей.
+
+Infrastructure подключается в Web для сборки приложения. Компоненты работают через контракты Application.
+
+## Программа
+
+Клиент принадлежит тренеру. У клиента несколько сохранённых месячных программ. Программа содержит недели, недели — тренировки, тренировки — упорядоченные блоки. Блок содержит ровно одно упражнение.
+
+Количество подходов (`SetsCount`) и отдых в минутах (`RestMinutes`) находятся у блока. У упражнения общие текстовые повторения и вес, текстовые разминка и примечание, nullable decimal процент от максимума, название, ссылка и флаг камеры. Процент вводит тренер; автоматического соответствия между повторениями и процентом нет. Сеты не поддерживаются.
+
+Общий отдых вычисляется как сумма `SetsCount × RestMinutes` всех блоков, включая отдых после последнего подхода. Текст повторений на эту формулу не влияет. Длительность тренировки (`Duration`) вводится тренером текстом и не вычисляется из отдыха.
+
+Миграция ExercisePrescription переносит общие вес и повторения из первого подхода, секунды делит на 60, старые сеты разделяет на отдельные блоки без перестановки упражнений. Перед применением нужна резервная копия. Откат с восстановлением индивидуальных подходов возможен только из резервной копии; автоматический Down запрещён.
+
+Упражнение программы хранит снимок названия и ссылки из библиотеки. Изменение библиотеки не изменяет старые программы. Копирование создаёт новые идентификаторы всех элементов программы. История — список сохранённых программ клиента, а не журнал каждого нажатия клавиши.
+
+## Конфигурация
+
+Настраиваемые значения задаются в appsettings.json и переопределяются стандартным провайдером переменных окружения .NET. В именах переменных `__` разделяет секции. Docker Compose читает `.env` и передаёт переменные контейнеру. Сам .NET файл `.env` автоматически не читает.
+
+Секреты не имеют рабочих значений по умолчанию и не хранятся в Git. Версии инструментов, имена маршрутов, CSS и структура данных не являются runtime-настройками.
+
+## Этапы
+
+1. Основа решения, правила разработки, предметные классы и конфигурация.
+2. PostgreSQL, авторизация, клиенты и библиотека упражнений.
+3. Редактор месячной программы и независимое копирование.
+4. PDF и проверка полного сценария в Docker.
+5. Адаптация под iPhone 15 — после первой версии.
+
+## Сохранение и безопасность
+
+UI использует Blazor Interactive Server. Каждая операция хранилища создаёт отдельный DbContext; общий контекст на долгоживущий Blazor circuit не используется. Репозитории проверяют тренера, полученного из серверного состояния авторизации. Экспорт получает идентификатор тренера из авторизованного HTTP-запроса.
+
+Сохранение небольшой месячной программы заменяет её внутренние дочерние записи одной транзакцией. Идентификаторы недель, тренировок и блоков являются внутренними и не используются в ссылках. Это сохраняет простую реализацию для первого этапа; при необходимости частичных обновлений контракт репозитория можно сохранить. Идентификатор программы стабилен, `Version` защищает от перезаписи из другой вкладки. История программ не удаляется.
+
+Автосохранение срабатывает после редактирования с задержкой из конфигурации. Незаполненное упражнение остаётся локальным черновиком до заполнения обязательных полей. Статус сохранения и ошибка видны в интерфейсе. Переход со страницы с несохранёнными данными требует подтверждения.
+
+ASP.NET Core Identity: хеширование паролей, блокировка повторных неудачных входов, antiforgery для форм, HTTP-only cookie и периодическая проверка security stamp. Регистрации нет. Первый тренер создаётся из конфигурации только в пустой базе. Для HTTPS за прокси задаётся адрес доверенного прокси; произвольные forwarded-заголовки не принимаются.
+
+PDF генерируется PDFsharp/MigraDoc, шрифты с кириллицей устанавливаются в Docker-образ. Каждая неделя — одна непрерывная альбомная A4-таблица. Общие заголовки недели и столбцов повторяются на продолжении страниц; тренировки разделяются цветными строками и имеют собственные итоги. Заголовок тренировки удерживается вместе с первой строкой, итог — с последней. Размеры, цвета и пути задаются в Pdf. Ссылки являются PDF-аннотациями; значок камеры встроен как статический рисунок и не зависит от emoji-шрифтов ОС.
+
+## Публикация Blazor в Docker
+
+В Web-проекте явно установлен `RequiresAspNetWebAssets=true`: при отдельном Docker-слое восстановления зависимостей Razor-файлы ещё не скопированы, поэтому автоматическое обнаружение компонентов не подходит. Dockerfile дополнительно проверяет наличие `wwwroot/_framework/blazor.web.js` после публикации. Это настройка сборки, а не runtime-параметр appsettings.
+
+Документация: https://learn.microsoft.com/aspnet/core/blazor/project-structure?view=aspnetcore-10.0
+
+## Группы библиотеки
+
+У `LibraryExercise` необязательная ссылка `GroupId` на `ExerciseGroup`, обе записи принадлежат тренеру. Упражнения внутри разных групп независимы. Добавление из другой группы создаёт новую запись с копией названия и ссылки. Перетаскивание меняет только `GroupId`, не переписывая остальные поля. `null` означает «Без группы».
+
+Удаление группы каскадно удаляет только её упражнения библиотеки. Снимки упражнений в программах не имеют внешнего ключа на библиотеку, поэтому история не меняется. Все операции проверяют тренера и у источника, и у целевой группы. Миграция ExerciseGroups добавляет таблицу групп и nullable GroupId: прежние упражнения остаются без группы.
+
+Поиск фильтрует по всем словам без учёта порядка, регистра и «ё/е»; точные совпадения и совпадения с начала имени выше совпадений внутри имени. В списке показана группа, чтобы различать независимые упражнения с одинаковыми названиями.
+
+Компонент ExercisePicker использует всплывающий список поверх страницы: ширина соответствует полю, направление раскрытия и высота зависят от доступного места окна. Нативный popover закрывается по Escape и клику снаружи. Двойной клик и Enter вызывают явный OnApply, одиночный клик меняет выбор; флаг применения предотвращает повторное добавление во время операции.

+# Проверка первой версии — 24 сентября 2026
+
+## Выполнено
+
+- Решение .NET 10 собирается без ошибок и предупреждений.
+- Пять тестов Application проходят: независимое копирование подходов, сохранение нагрузок при объединении/разделении и перемещении, запрет потери подходов при разном их количестве, добавление круга, проверка отрицательного веса и схемы видеоссылки.
+- Docker-образ собирается; публикация отдельно проверяет наличие скрипта Blazor.
+- Два контейнера запускаются в общей сети; PostgreSQL проходит healthcheck, миграция применяется, первый тренер создаётся из окружения.
+- В Chrome проверены вход, создание клиента и программы, ручное добавление упражнения, разные веса 40/45/50 и 12/14/16 по подходам, сохранение и повторное открытие.
+- Проверены объединение/разделение сета, изменение порядка, перетаскивание, библиотека и отмена удаления блока.
+- Проверена независимая копия программы: изменение её веса не затрагивает оригинал.
+- Проверены две вкладки: устаревшая версия не перезаписывает более новую.
+- Неавторизованный запрос PDF перенаправляется на вход.
+- PDF скачан из приложения и отрендерен: кириллица, значки камеры, веса и шесть кликабельных ссылок присутствуют.
+- Отдельная длинная тренировка экспортирована на шесть страниц: все 18 упражнений и 54 ссылки сохранены; переносы страниц просмотрены.
+
+## Границы проверки
+
+Проверка проведена локально в Docker на macOS и в настольном Chrome. Публичный TLS-прокси, нагрузка нескольких тренеров и мобильный интерфейс не проверялись. Данные проверки явно помечены как демонстрационные. Результаты и скрипты ручной браузерной проверки находятся в игнорируемом `artifacts/qa`; это не данные реальных клиентов.
+
+## Общие параметры упражнений — 25 сентября 2026
+
+- Убраны индивидуальные подходы и сеты. Добавлены общие повторения, текстовый вес, разминка, примечание, ручной процент, отдых в минутах и ручное время тренировки.
+- 8 тестов: независимое копирование полей, валидация, порядок блоков, общий отдых с паузой после последнего подхода.
+- Перед миграцией создана локальная резервная копия в игнорируемом каталоге backups. Миграция проверена на отдельной копии PostgreSQL: 19 упражнений из 15 блоков перенесены в одиночные блоки; проверены порядок, названия, ссылки, камера, число подходов, первые вес/повторения и перевод секунд в минуты.
+- Браузерные проверки выполнялись на отдельном временном экземпляре приложения и копии БД: ввод новых полей, сохранение и перезагрузка, независимая копия блока, текстовый вес, дробный отдых, итоги 6 и 10,5 минуты, отсутствие управления сетами, экспорт HTTP 200.
+- PDF проверен по тексту и структуре без рендеринга страниц: альбомная ориентация, новые колонки, кликабельные аннотации, встроенные камеры, итог отдыха и ручное время. Длинный PDF: все 18 упражнений на 3 страницах, повтор заголовков, текст в границах страниц.
+- По просьбе пользователя скриншоты и визуальная проверка PDF не выполнялись.
+
+## Единая PDF-таблица недели — 25 сентября 2026
+
+- Каждая неделя экспортируется одной таблицей с общими заголовками и последовательными тренировками; после каждой тренировки свой итог.
+- Проверена структура документа: одна таблица на неделю, только две общие строки заголовка повторяются при переносе.
+- Тестовый PDF: две короткие тренировки на одной странице без повторения заголовков между ними; длинная тренировка на следующих страницах, пустая тренировка, отдельные итоги и кликабельные ссылки. Проверены альбомная ориентация, повтор общих заголовков и границы текста.
+- Проверки без скриншотов и рендеринга страниц.
+
+## Группы библиотеки и поиск — 25 сентября 2026
+
+- 11 тестов проходят, включая точные/начальные совпадения, поиск по нескольким словам, регистр, «ё/е» и отсутствие результатов.
+- Миграция ExerciseGroups соответствует модели EF Core. На отдельной копии PostgreSQL проверен переход старых упражнений к nullable GroupId без удаления исходных записей.
+- На отдельном тестовом экземпляре проверены создание и переименование групп, независимое копирование упражнения между группами, drag and drop в группу и «Без группы», сохранение после перезагрузки.
+- Проверены отмена удаления группы, удаление группы с упражнениями, сохранение независимой копии в другой группе и индивидуальная корзина.
+- В конфигураторе проверены фильтр группы, поиск, пустой результат, блокировка добавления без выбранного упражнения; добавленное в программу упражнение остаётся после удаления библиотечной группы.
+- Заодно подтверждены значения по умолчанию: время новой тренировки «1 час», процент нового упражнения 80.
+- Все UI-проверки выполнены без скриншотов. Тестовые изменения делались только в отдельной базе.
+
+## Выпадающий поиск — 26 сентября 2026
+
+- Постоянный список заменён popover со строкой поиска; ширина соответствует полю, высота и направление раскрытия зависят от свободного места.
+- На отдельной копии базы проверены: скрытое начальное состояние, фильтрация, двойной клик без повторного добавления, одиночный выбор с кнопкой «Добавить», стрелки и Enter, Escape, закрытие по клику снаружи, отсутствие результатов и сохранение после перезагрузки.
+- Проверено размещение внутри уменьшенного окна и двойной клик при создании независимой копии упражнения в группе.
+- Сборка прошла. Скриншоты не выполнялись.
+
+## Удаление клиента — 29 сентября 2026
+
+- В карточку клиента добавлена корзина с подтверждением удаления клиента и всех его программ.
+- Сборка без предупреждений и ошибок, 11 тестов прошли; приложение обновлено в Docker.
+- В браузере на специально созданном тестовом клиенте проверены отмена удаления с сохранением программы, подтверждение, возврат к списку и недоступность удалённых клиента и программы по прямым ссылкам. Тестовый клиент удалён. Скриншоты не выполнялись.
+
+## Данные клиента в PDF — 29 сентября 2026
+
+- Миграция ClientProfile добавляет Goal, TrainingSchedule и HealthStatus с пустыми значениями; существующий столбец Notes сохраняется без изменений.
+- 11 тестов прошли; EF Core не обнаружил расхождений модели и миграций. Сборка Docker и применение миграции успешны.
+- На специально созданном клиенте проверены порядок полей, сохранение и загрузка после обновления страницы, экспорт PDF. Тестовые клиент и программа удалены после проверки.
+- Из PDF извлечены все новые значения; таблица содержит четыре строки и два столбца, находится перед неделями и встречается один раз. Проверены альбомные страницы и отсутствие приватной тестовой заметки. Скриншоты и визуальный рендер не выполнялись.
+
+## Удаление программы — 29 сентября 2026
+
+- В истории программ клиента добавлена корзина с подтверждением по названию программы. Удаление ограничено текущим тренером; дочерние недели и тренировки удаляются каскадно.
+- Сборка без предупреждений и ошибок, 11 тестов прошли; Docker-приложение обновлено.
+- В браузере без скриншотов на собственных тестовых данных проверены отмена, подтверждение, обновление счётчика, закрытие формы копирования удалённой программы, сохранение результата после перезагрузки и недоступность удалённой программы по ссылке. Клиент и другая программа сохранились. Тестовые данные удалены после проверки.
+
+## Импорт упражнений из таблицы — 29 сентября 2026
+
+- Сборка без предупреждений и ошибок, 16 тестов прошли. Тесты разбора буфера покрывают кавычки Excel, переносы внутри ячеек, пустые ячейки, CR/LF/CRLF, большие вставки и лимиты; проверена валидация ссылок и номера ошибочной строки.
+- В Docker-приложении без скриншотов проверена вставка 250 строк одним событием буфера обмена, автоматическое расширение таблицы, сохранение после перезагрузки, импорт в новую/существующую группу и без группы.
+- Ошибочная ссылка оставляет данные в модальном окне и не создаёт ни группу, ни упражнения. Проверены лишний столбец, обязательность названия новой группы, ручное исправление ячеек, вставка только в столбец ссылки, добавление/удаление строк, отмена и Escape.
+- Сохранённая ссылка проверена в библиотеке. Собственные тестовые записи удалены после проверки. Настоящее приложение Excel не автоматизировалось: использовалось событие paste с табличным текстом формата Excel.
+
+## Очистка поиска после добавления — 29 сентября 2026
+
+- После успешного добавления сбрасываются текст поиска и активный пункт, список закрывается; фильтр группы сохраняется. Сброс явно запрашивается родителем, поэтому обычный ввод и перерисовка не стирают следующий запрос.
+- Сборка успешна; приложение обновлено в Docker. В браузере без скриншотов проверены добавление кнопкой, двойным кликом и Enter, очистка поиска и выбора, закрытие списка и сохранение следующего введённого запроса. Собственные тестовые данные удалены.
+
+## Плашка отмены удаления — 29 сентября 2026
+
+- Плашка видна только в тренировке, где удалён блок, и исчезает через Planner:UndoDeleteDurationSeconds (по умолчанию 10 секунд). Повторное удаление заменяет предыдущую отмену и перезапускает таймер.
+- Таймер отменяется при восстановлении блока, удалении исходной тренировки/недели, смене программы и закрытии редактора.
+- Сборка успешна, 16 тестов прошли. В браузере без скриншотов на собственных тестовых данных проверены переключение тренировок, восстановление блока, автоматическое исчезновение и отсутствие повторного появления. Тестовые данные удалены; Docker-приложение обновлено.
+
+## PDF без названия программы — 29 сентября 2026
+
+- Название программы удалено из содержимого и метаданных PDF.
+- Сборка успешна, Docker-приложение обновлено. В тестовом экспорте проверено отсутствие названия на всех четырёх страницах и в метаданных, наличие данных клиента. Собственные тестовые записи удалены. Скриншоты не выполнялись.
+
+## Отступ после данных клиента в PDF — 29 сентября 2026
+
+- Добавлены пять пустых строк только между таблицей данных клиента и первой неделей. Настройка: Pdf:ClientDetailsGapLines, переопределение через .env.
+- Сборка и Docker-обновление успешны. Координаты текста тестового PDF подтверждают смещение первой недели вниз при неизменных следующих неделях и количестве страниц. Скриншоты не выполнялись; собственные тестовые записи удалены.
+
+## Ширина таблицы и ресурс камеры — 29 сентября 2026
+
+- Ширина таблицы PDF увеличена с 25,5 до 27,5 см настройками столбцов. Приложенный PNG без изменений включён как EmbeddedResource в Infrastructure; размер камеры 18 pt настраивается через Pdf:CameraSizePoints.
+- Иконка выровнена по центру абзаца и вертикально по центру ячейки. Сборка и Docker-обновление успешны.
+- Из PDF, экспортированного Docker-приложением, извлечена иконка: пиксели совпадают с исходным PNG. По координатам проверены ширина таблицы, границы страницы и центрирование (горизонтальное отклонение 0 pt, вертикальное менее 1 pt).
+- Скриншоты не выполнялись. Собственные тестовые данные удалены после экспорта.
+
+## Полные ссылки и центрирование в PDF — 29 сентября 2026
+
+- Вместо «Открыть видео» выводится полный URL с невидимыми возможностями переноса; адрес гиперссылки остаётся исходным.
+- Все столбцы после «Примечания», включая заголовки и итоговые значения, выровнены по горизонтальному и вертикальному центру.
+- Сборка и Docker-обновление успешны. В тестовом PDF проверены полный длинный URL внутри ячейки, неизменный адрес перехода в аннотациях PDF и центрирование числовых ячеек по координатам (отклонение менее 1 pt). Скриншоты не выполнялись; собственные тестовые данные удалены.
