0.1.0

[0.1.0] - 2026-08-31

Fixed

• CPI/SCPI resampling definitions now match the FDFI paper. method='cpi'
  computes one half the average per-resample loss difference, while
  method='scpi' averages counterfactual predictions before applying the
  loss difference. Previously the method labels were reversed and the
  loss-first score omitted CPI's one-half normalization.
• Added exact formula tests and a Gaussian OT simulation test for the
  squared-loss population agreement of normalized CPI and SCPI.

Changed

• Migration: with identical data and random draws, old method='cpi' is
  new method='scpi'; old method='scpi' is twice new method='cpi'.
  Estimator-dependent importance values, standard errors, intervals, and plots
  should be regenerated after upgrading.
