 Проверки: TypeScript всего проекта прошёл; браузерный тест v9 (12 строк, сортировка, раскрытие) прошёл. Повторный lint группы: **21 ошибка, 27 предупреждений**, актуальный компактный отчёт — `docs/reui-migration-lint.md`. Production build не повторялся после этой локальной правки; предыдущая сборка этапа прошла. Этап 2 остаётся в работе; следующий объём прежний.
 
+## Этап 2 — завершение
+
+Продолжение от `f9a4a07` в `codex/reui-v9-migration`. Записи о промежуточных остановках выше — история; текущий следующий шаг — **этап 3**.
+
+### Результат
+
+- Серверы используют ReUI Data Grid/TanStack 9.2.4 и новый `FilterQuery`; таблица сохраняет все строки, сортировку, детали и подтверждённые операции этапа 1. Для раскрытия есть отдельная кнопка с `aria-expanded`, работающая с клавиатуры. При пустом результате фильтрации показывается «Нет совпадений», а не предложение добавить первый сервер.
+- `ServerFilters` повторяет контракт официального `c-filters-1`. Поля `country/status/type` имеют `type: select`, потому что данные скалярные. Варианты множественного выбора задаются операторами. Добавлены русские подписи Filters, вычислитель дерева `applyFilterQuery` и временный `migrateFilterQuery` для AND-массива старых условий. Неизвестное условие не расширяет выборку, незавершённые условия не превращают OR в истинное выражение.
+- `DataPageToolbar.filterControl` позволяет переносить потребителей по одному; старые props сохранены только на период этапов 3–4. Новые импорты Filters обязательно указывают `/filters/filters`, пока существует старый одноимённый файл.
+- Выполнены локальные исправления совместимости исходников ReUI с React Compiler. Контекст Data Grid передаёт актуальный снимок данных; императивный координатор ширины получает только закоммиченные React значения. Кэш подписей Cascader обновляется без мутации ref во время рендера; измерения запускаются через ResizeObserver/кадр браузера, отложенная навигация отменяется при смене контекста. Draft и автооткрытие Filters синхронизируются до рендера дочерних редакторов. Убраны неиспользуемые импорты и лишние вычисления. Правила lint не отключались, публичные API и композиция сохранены. При будущем обновлении реестра эти исправления сравнить с upstream, не перезаписывать автоматически.
+
+### Приёмка
+
+| Проверка | Результат |
+| --- | --- |
+| `npm run test:servers` | 17 браузерных тестов прошли, включая операции, сортировку 12 строк, фильтрацию AND, изменение/сброс, Escape и клавиатурное раскрытие |
+| `npx tsx --test lib/data-filters/apply-filter-query.test.ts` | 6 тестов прошли: AND/OR, отрицание, черновики, пустые/неизвестные условия, эквивалентность поддерживаемых старых операторов |
+| TypeScript и `npm run build` | Успешно, 34 статические страницы |
+| Lint изменённых участков и новой группы ReUI | 0 ошибок, 1 предупреждение `react-hooks/incompatible-library` для виртуализатора. React Compiler пропускает его оптимизацию; [отчёт](reui-migration-lint.md) |
+| Визуальная проверка | Просмотрены экраны 1440×1000 и 390×844. Page overflow отсутствует; широкая таблица сохраняет горизонтальный скролл внутри своего контейнера |
+| ReUI audit | Checklist получен; проверены композиция Frame/base-nova, API, типизированные HTTP-данные, подписи, состояния и фокус эталона. Правки internals ограничены описанной совместимостью, без смены дизайна |
+
+Границы приёмки: моки HTTP не подтверждают реальные права или применение RouterOS. Общая мобильная шапка обрезает часть действий, KPI занимают много высоты — исходные задачи этапов 6–7. Некоторые служебные объявления вложенного Cascader ещё английские — завершить локализацию на этапе 7. Все режимы DnD/виртуализации/автоподбора ширины не были проверены браузером на этом этапе; их проверять при переносе использующих их экранов. Изменённый способ публикации контекста Data Grid требует профилирования больших таблиц на этапе 12. Это не полная приёмка доступности/производительности всего приложения.
+
+### Образец следующего переноса
+
+1. В выбранном доменном grid заменить `react-table-v8` на `react-table`, legacy-оболочку на `DataGridShell` и заголовки на новый `DataGridSortHeader`.
+2. Тип колонок — `ColumnDef<DataGridFeatures, T>`, таблицы — `Table<DataGridFeatures, T>`. Использовать `useTable({ features: dataGridFeatures, ... })`; удалить старые `get*RowModel`. Сверить переименованные sorting/pinning/resize props с установленным API. Сохранить стабильный `getRowId`.
+3. Явно определить пагинацию: для полного списка без панели — `manualPagination: true`; для серверной — передавать реальный `rowCount`; для клиентской — подключить панель и контролируемую страницу.
+4. Для Filters перенести поля `key → id`, выбрать тип по данным, сохранить AND через `migrateFilterQuery`. Вычислитель сейчас поддерживает только операторы скалярных фильтров серверов и прежние текстовые contains; перед переносом дат, чисел или массивов расширить вычисление и тесты. Нельзя просто сплющить OR-дерево.
+5. Проверить фильтрацию, сортировку, сброс/страницу, раскрытие и действия. Старую основу удалять только после последнего потребителя в этапе 4.
+
+Следующий шаг: проверить квоту и состояние файлов; выполнить только этап 3 (обзор, мониторинг, трафик, статистика и справочники) в этой ветке, перечислить оставшихся legacy-потребителей и сделать локальный коммит без push. Перед миграцией виртуализированных таблиц добавить профильные проверки указанного выше риска контекста. Этапы 2–4 не выпускать до общей регрессии этапа 4.
+
 ## Карта миграции
 
 Текущая связка: @tanstack/react-table ^8.21.3, @tanstack/react-virtual ^3.14.4, base-nova. Актуальный ReUI MCP ранее подтвердил useTable/dataGridFeatures для Data Grid и дерево FilterQuery вместо filters/onChange для Filters. Перед установкой перепроверить совместимые версии, сохранить семантику существующих фильтров (простые условия → AND) и закрепить lockfile.
