LeanPool.MarkoffModP.BGS.Markoff.MiddleGame.PairedMaximalDivisorOrderEscape

Paired nonparabolic order escape using maximal divisors #

This is the geometric diagonalized-fiber step for the paired maximal-order union. A hypothetical bounded target coordinate is first shown to be nonparabolic. Its trace is then represented by a non-two-torsion element of a maximal candidate subgroup, exactly the kind of witness excluded by the paired finite escape theorem.
