Every type category in [basic.fundamental] (integrals, narrow character types, floating points, ...) don't mention cv-qualified types. For example [basic.fundamental]p7:
Types bool, char, char16_t, char32_t, wchar_t, and the signed and unsigned integer types are collectively called integral types.
Is const bool an integral type? Obviously yes, but this is not mentioned anywhere. Because a lot of type categories are introduced in that section, maybe add a new paragraph that says something like:
If a type T is a X type, where X is one of the types of types mentioned in this section, then cv-qualifiers T is also a X type.
