Companion note, version 1.10

Withdraws a priority claim in Section 6. The note called the transcendence degree two of two unrelated candidates of commensurable moduli "the first constraint of any kind on such families"; Diaz 2007, Corollaire 4(2), a consequence of Roy's strong six exponentials theorem, already puts one of u/v and v/u outside the algebraic span of 1 and the logarithms for such a pair, and the sentence now cites it. The mirrored library holds 262 results.
