-# План frontend части Calendar Run
-
-## Исходные опоры
-
-- UI и UX принципы: минимализм, воздух, акцент на данных, спокойная палитра, быстрые сценарии (дизайн-токены в `frontend/src/styles/tokens.css`).
-- Продуктовые ограничения и структура экранов сверяем с [d:\vaka.pro\calendar_run\PLAN.md](d:/vaka.pro/calendar_run/PLAN.md).
-- Интеграционный контракт берём из [d:\vaka.pro\calendar_run\docs\backend-api-for-frontend.md](d:/vaka.pro/calendar_run/docs/backend-api-for-frontend.md).
-- Общий контекст запуска/окружения — [d:\vaka.pro\calendar_run\README.md](d:/vaka.pro/calendar_run/README.md) и [d:\vaka.pro\calendar_run\docs\backend.md](d:/vaka.pro/calendar_run/docs/backend.md).
-
-## Границы версии (V1)
-
-- Только frontend + интеграция с текущим API.
-- Статус `зарегистрирован` трактуется как UI-вариант `planned` (без изменения backend-контракта).
-- Для completed-забегов обязательно показываем `темп`; считаем на фронте из `finishTime` и `distanceKm`.
-- Для completed-забегов поле `место` (`finishPlace`) доступно в API (миграция 002, маппер, DTO); фронтенд отображает его в карточке и таблице сравнения.
-
-## Архитектура frontend
-
-- Базовая структура: `frontend/src/app`, `frontend/src/pages`, `frontend/src/components`, `frontend/src/api`, `frontend/src/features`, `frontend/src/lib`, `frontend/src/styles`.
-- Дизайн-система на CSS variables: токены цвета/типографики/отступов/радиусов, единые состояния (`success`, `warning`, `error`).
-- БЭМ для всех UI-блоков и модификаторов (`block`, `block__element`, `block--modifier`).
-- Единый слой API-клиента:
-  - `GET /races`, `GET /races/:id`, `POST /races`, `PATCH /races/:id`, `DELETE /races/:id` (если используется UI-сценарием).
-  - Типы `Race`, `RaceStatus`, DTO для POST/PATCH.
-  - Централизованный маппинг ошибок API (`validation_error`, `not_found`, `database_unavailable`, `conflict`) в UX-сообщения.
-
-## Экранная модель и сценарии
-
-- Dashboard:
-  - `Ближайший старт`, `Последний результат`, `Личный рекорд`, `Сезон`.
-  - CTA к календарю и добавлению старта.
-- Календарь стартов:
-  - Переключение `Будущие` / `Прошедшие`.
-  - Карточка старта: `title`, `date`, `distanceKm`, статус-лейбл.
-- Карточка старта:
-  - Базовые поля + `finishTime`, вычисляемый `pace`, `finishPlace`, `notes`.
-- PR блок:
-  - Дистанции: 5K, 10K, 21.1, 42.2 (согласно UI-инструкции).
-  - Расчёт по completed-забегам с валидным `finishTime`.
-- Сравнение стартов (ключевая фича):
-  - Таблица/карточки по годам с `time`, `pace`, `finishPlace`.
-  - Если `finishPlace` не заполнено — graceful-degradation: колонка в состоянии «нет данных».
-
-## UX и визуальные требования
-
-- Визуальная система: светлый фон, белые карточки, один акцентный цвет, без кислотных сочетаний.
-- Иерархия типографики: H1/H2/body/caption, крупные числовые метрики.
-- Минимум визуального шума, 2–3 клика на частые действия.
-- Консистентные состояния загрузки/ошибок/пустых данных.
-- A11y-базис: фокус-стили, клавиатурная навигация, контраст, корректная разметка интерактивных элементов.
-
-## Зависимая задача (выполнена)
-
-- Поле `finishPlace` добавлено в модель `Race`: миграция `002_finish_place_and_registered_status.sql`, маппер `race.ts`, DTO, API-документация.
-- Frontend-типы, карточка и блок сравнения используют `finishPlace`.
-
-## Порядок реализации
-
-1. Подготовить каркас frontend и дизайн-токены (BEM + CSS variables).
-2. Реализовать API-клиент и типы данных с обработкой ошибок.
-3. Собрать Dashboard и календарные списки (будущие/прошедшие).
-4. Реализовать карточку старта с вычислением `pace` на клиенте.
-5. Реализовать PR и блок сравнения стартов с fallback для `place`.
-6. Добавить состояния пустых данных/ошибок/загрузки и а11y-полировку.
-
-## Definition of Done для frontend
-
-- Все ключевые экраны из UI-инструкции доступны и консистентны визуально.
-- API-интеграция работает по текущему контракту без локальных обходов хранилища.
-- `pace` считается корректно для completed-забегов.
-- `registered` не ломает модель: визуально интерпретируется в рамках `planned`.
-- `finishPlace` интегрирован; при отсутствии значения — безопасный fallback в UI.

-# Calendar Run — план продукта
-
-Монорепозиторий: **backend** (Express + PostgreSQL) и **frontend** (React + Vite). Цель — календарь стартов с метриками бегуна: планирование, результаты, PR и сравнение.
-
-## Вне объёма (намеренно)
-
-- Авторизация, мультипользовательность, личные кабинеты.
-- Парсинг сайтов организаторов и автозагрузка результатов.
-- Отдача статики SPA с того же процесса, что и API (фронт — отдельный Vite/build).

-## HTTP API (минимум)
-
-- `GET /health` — liveness без БД.
-- `GET /ready` — readiness (подключение к БД; в режиме mock считается доступной — только для dev/CI).
-- `GET /races` — список; query: `year`, `month` (целые; `month` 1–12).
-- `GET /races/:id`, `POST /races`, `PATCH /races/:id`, `DELETE /races/:id`.
-
-Ошибки: JSON, единый стиль (`validation_error`, `not_found`, `conflict`, `database_unavailable`). Подробности — `[docs/backend-api-for-frontend.md](docs/backend-api-for-frontend.md)`.
-
-## Seed
-
-- Файл `[import/races_2026_calendar.csv](import/races_2026_calendar.csv)`.
-- Стабильный `id`, upsert по `id`. Повторный запуск безопасен.
-
-## Режим без PostgreSQL (dev/CI)
-
-Переменная `CALENDAR_RUN_MOCK_DB=1` (или `true`): HTTP-обработчики используют заглушку пула **без** реальной БД. **Не использовать** для `npm run db:migrate` и `npm run seed` — нужен настоящий Postgres и `DB_`*.
-
-## Frontend (SPA)
-
-- Маршруты: дашборд (`/`), список стартов (`/races`), карточка (`/races/:id`).
-- Дашборд: ближайший старт, последний результат, PR, сезон, PR по ключевым дистанциям, сравнение завершённых стартов, при необходимости — лёгкая визуализация прогресса.
-- Список: будущие / прошедшие; фильтрация по году и месяцу через API.
-- Стили: BEM и дизайн-токены (см. `frontend/src/styles/tokens.css`).
-
-## Критерии готовности текущей итерации
-
-- Документация согласована с кодом: `[README.md](README.md)`, `[docs/backend.md](docs/backend.md)`, `[docs/backend-api-for-frontend.md](docs/backend-api-for-frontend.md)`.
-- Миграции и seed воспроизводимы; контракт API покрыт smoke-тестами в CI при необходимости с mock-БД.

+# Auth rollout
+
+Before applying auth and ownership migrations in production:
+
+1. Run `pg_dump` for the target database and keep the dump until verification is complete.
+2. Record the rollback command for restoring that dump if migration or legacy race claiming fails.
+3. Record the current race count with `SELECT count(*) FROM races;`.
+4. Run migrations.
+5. After the first email-verified user claims legacy races, verify:
+   - `SELECT count(*) FROM races;` matches the pre-migration count.
+   - `SELECT count(*) FROM races WHERE owner_user_id IS NULL;` is `0` before planning the follow-up `NOT NULL` migration.
+
+Seed/import after auth requires `SEED_OWNER_USER_ID` or `SEED_OWNER_EMAIL` once users exist. It inserts missing seed races for that owner and does not overwrite user-edited races.

+# План корректировок: форма старта, время, календарь стартов
+
+Краткое описание реализованных изменений в клиенте **runners-calendar** (версия клиента см. в футере приложения).
+
+## 1. Форма старта (редактирование прошедшего события)
+
+При **редактировании** старта, чья **дата уже в прошлом**, в блоке «Организация» скрыты поля, неактуальные после забега:
+
+- сайт организатора;
+- время старта;
+- расписание кластеров;
+- выдача номеров.
+
+Значения по-прежнему хранятся в состоянии формы и отправляются при сохранении (не затираются). Утилита: `isRaceDateInPast` в `frontend/src/lib/raceMetrics.ts`.
+
+## 2. Время старта
+
+Вместо свободного текста — три селекта (часы, минуты, секунды), компонент `StartTimeSelects` в `frontend/src/components/StartTimeSelects.tsx`. Сохраняется строка `HH:mm:ss` или пусто → `null` в API. Поддерживается разбор старых значений `HH:mm` при загрузке.
+
+## 3. Список на странице «Календарь стартов»
+
+Для стартов со статусом **«внесите результат»** вся карточка — ссылка на `/races/:id/edit` с лёгким увеличением и тенью при наведении/фокусе (токен `--shadow-card-lift`).
+
+## 4. Виды: список и календарь
+
+- Переключатель **Список / Календарь**, выбор сохраняется в `sessionStorage` (`races-view-mode`).
+- **Календарь:** загрузка гонок за выбранный **год** (без фильтра месяца в запросе), отображение сетки месяцев.
+- При выборе **месяца** в фильтре — крупная сетка этого месяца и компактная навигация по остальным месяцам + «Весь год».
+
+## 5. Ячейка даты в календаре
+
+- Наведение или фокус: всплывающая панель — либо «Стартов нет» и кнопка **Добавить** (`/races/new?date=YYYY-MM-DD`), либо список стартов со ссылками на карточки и **Добавить**.
+- Клик по числу — страница дня `/races/day/:ymd`.
+
+## 6. Страница дня
+
+Маршрут `races/day/:ymd`: список стартов на дату, пустое состояние, кнопка **Добавить** с предзаполнением даты через query.
+
+## 7. Новый старт с датой из календаря
+
+`RaceFormPage` читает query-параметр `?date=YYYY-MM-DD` при создании старта.
+
