One parent parameter, not one parameter per derivative

parent parameter, not one parameter per derivative{ Theorem thm:independence concerns the dimension of a distribution orbit, not the number of independent normalization parameters. VII-D fixes the parent conversion to $c_{ab}r$ (thm:conversion). If differentiation is imposed as a compatibility identity, the parent change $u\mapsto u+cr$ induces

with the same parent coefficient $c$. The compatible freedom can therefore be one-dimensional even though the derivative orbit is infinite-dimensional. No algebra obstruction or new independent constants are inferred.}
