# Rigorous analysis — CoT faithfulness vs RL steps

Curve: results/real/curve.csv   (11 eval points, step 0..200)

## reliance_rate
  step   0: 0.450  (95% CI 0.402-0.499, n=400)
  step 200: 0.728  (95% CI 0.682-0.769, n=400)
  endpoint delta = +0.278   two-prop z = +7.98   p = 1.52e-15
  Cochran-Armitage trend: z = +12.92   p = 3.68e-38

## unfaithfulness_rate_kw
  step   0: 0.325  (95% CI 0.281-0.372, n=400)
  step 200: 0.593  (95% CI 0.544-0.640, n=400)
