  u target     : excess  (signed excess of p; ~0 = trust p)
  excess mean  : +0.0005   (p calibrated on avg if ~0)
  u mean       : -0.0421   (should track excess mean)
  u corr       : 0.0032   (Pearson u vs realized excess)
  u R^2        : -0.0323   (>0 = beats constant)
  u spread     : -0.0004   (excess top-q u minus bottom-q u; want >0)
  const Huber  : 0.1130   (u useful if U-loss < this: YES)

  Note: no held-out validation split -- every training example
  is drawn without replacement from ~2.4B windows, so batches
  are effectively unseen data by construction.
