Enum ArgumentOrigin 

pub enum ArgumentOrigin {
    KernelPosition(usize),
    Guest(Symbol),
}

The exact place at which an argument entered the call boundary.

Origins are data rather than formatted diagnostics so a guest can retain its own source vocabulary while still identifying every occurrence.

Variants

KernelPosition(usize)

A zero-based position in the kernel’s evaluated Args sequence.

Guest(Symbol)

A guest adapter’s stable source location or expansion identity.
