 - HoldMyItems Scripted: знаки осей `M:rotate`, видимость Lua-частиц, анимация квадов на реальной модели.
 - GuiPresence: нужен запущенный стек (`backend/scripts/dev-stack.sh`) и два клиента с привязанными аккаунтами на одном сервере.
+- SpatialGui (инвентарь был прозрачным): сверено с `ref/mods/Spatial-GUI`; убрано ванильное затемнение в захвате (`ScreenSpatialBackgroundMixin`) и

+  следующий подозреваемый: глубина захвата (clear 1.0) и HUD внутри захвата (у эталона захватывается только экран, отдельным GuiRenderer).
 - Войсчат с настоящим SVC 2.6.24 (события mute/speaking, значок шапки HUD).
 - Размер плашки описания в ClickGUI и авто-масштаб тултипа при GUI Scale 2/3/4.
