Раздел «Маршрутизация» с подпунктами (Обзор, Правила, Наборы правил, DNS, Исходящие, Система, JSON) редактирует тот же активный native JSON. Формы строятся из JSON Schema закреплённого ядра (sing-box schema), своей модели маршрутизации нет; неизвестные ключи и форма Listable сохраняются. «Проверить» запускает sing-box check в фоне. DNS больше не перезаписывается принудительно: при обновлении шаблонов нетронутые верхние секции следуют за стоком, изменённые остаются. Сброс к стоку — вручную, целиком или по разделу.

"""One editing session of the active sing-box config for all routing sub-pages.
|
|
|
|
Direction of truth: the session keeps the editor text. Structured pages edit
|
|
the parsed document in place and call :meth:`SingboxSession.mark_edited`; the
|
|
text is regenerated from the document only when it is actually needed. The raw
|
|
JSON page sets text directly; it is parsed when the user leaves that page. If
|
|
the text is not valid JSON, structured pages become read-only instead of ever
|
|
serialising a stale document over the user's raw edits.
