What? No.

It's an interaction with `pure` factory functions. Nothing at all to do 
with inheritance.

I understand what is going on without asking Gemini.

You specifically asked to modify `immutable` data, the conversion from 
mutable to `immutable` is needed for this.

Violating `const` does not require a `pure` annotation, but violating 
`const` alone will likely not allow you to modify `immutable` data in 
this specific case.
