Struct EnumVariantShape 

#[repr(C)]
pub struct EnumVariantShape {
    pub name: &'static str,
    pub payload: &'static [*const TypeDescriptor],
}

One variant of an enum shape: its source name plus the descriptors for its payload slots, in declaration order. A payload-less variant has an empty slice.

A slot may be null, meaning the producer had no static type for it — exactly the encoding TupleSchema uses. The runtime’s own Option schema is the motivating case: praxis_map_get learns V from the value it found, never from a static type, so Some’s slot is unknown there and known (Int, Text, …) in the schema the codegen builds for the same Option. The two must still be one type, and the value’s descriptor — read off its header, so never wrong — answers for an unknown slot.
