inlineconstexpr

Always fails because no_prev carries no retrievable value.

no_prev still exposes the same contains<T>() / get<T>() protocol shape as a concrete parent-slot view so generic resolution code can be written against one interface. The operation itself is invalid here, so get<T>() emits a targeted compile-time error if some code path tries to fetch a direct-parent value when none exists.
