I disagree with the expected result of the test, and don't think the description matches the test.

The loaded module has no context item declaration, therefore doesn't place any restrictions on the context item type.

When the module is compiled, the compiler introduces dynamic type checking for the assignment

declare variable $cim:context as node() := .;

which will trigger an XPTY0004 if $cim:context happens to be evaluated.

xquery version "3.1";

module namespace cim = "http://www.w3.org/fots/fn/load-xquery-module/context-item/module";

declare variable $cim:context as node() := .;

declare function cim:get-context-child() as node()* {
    $cim:context/child::node()
};
