    Interface ListSnapshot

    The binding-facing view of a list — an eager ids snapshot plus the ops. One shared type for both frameworks, the FieldSnapshot precedent: React's useList and Svelte's list handle both return it.

    interface ListSnapshot {
        ids: readonly string[];
        add(
            seed?: Record<string, unknown>,
        ): ListOpRefusal | { id: string; success: true };
        duplicate(id: string): ListOpRefusal | { id: string; success: true };
        move(id: string, index: number): ListOpRefusal | { success: true };
        remove(id: string): ListOpRefusal | { success: true };
    }
