    Variable UMB_TREE_ITEM_BASE_CONTEXTConst

    The base tree item context — the shared contract every tree item provider implements, covering item data, selection, active state, path, and entity actions. Matches any provider, whether a full tree item context or a card api. Use this in entity action conditions that should work regardless of which tree view is active.

    For child loading or expansion state, use UMB_TREE_ITEM_CONTEXT instead.
