name: peak_umm_iter
intent: >
  Locate each Z's true peak unseen_mismatch training iteration more precisely
  than the six coarse waypoints of paper_long_iter allow: take the coarse
  argmax per Z, then run a dense 9-point geometric bracket around it.
hypothesis: >
  The coarse waypoints under-sample the peak: the true peak iteration is
  interior to the coarse bracket for mid/high Z, decreases monotonically with
  Z, and the refined peak values exceed the coarse ones where the coarse grid
  straddled a narrow peak.
