I think this needs an EXCEPT clause.  Something like:

The lowest numbered existing Rule is the Root.  Every existing Rule except
the Root has an existing Rule as a Parent, and is a Child of its Parent.
The default parent for all children is the Root.

Otherwise the Root is its own Parent.  And as this is intended to be a tree
growing upwards, one cannot go Below the Root.
