Conditional fourteen-point theorem for Erdős Problem 132 #

This file eliminates the three classified thirteen-point branches after the internal diameter descent. The two exceptional templates contradict the fifteen-pair ceiling. In the regular branch, insertion counts give one rare distance and two copies of each regular chord; the explicit coordinate moments then contradict planar Cauchy--Schwarz.

The result is conditional on the two interfaces in PublishedInputs.lean. The planar diameter bound is proved internally. It does not settle Erdős Problem 132 in general.

      Conditional end-to-end fourteen-point case of Erdős Problem 132. The two arguments are precisely the remaining named published interfaces; the planar diameter bound, counting, deletion, classified-case elimination, and moment steps are proved internally.
