Representative TARP ATRC curves. Left: Faraday thin N = 1, the largest deviation in the matrix and formally flagged underconfident, yet within ≲5% coverage of the ideal diagonal at every credible level. Center: Burn slab N = 2, a typical calibrated example. Right: internal dispersion N = 3, calibrated at the information floor set by the noise model. Shaded regions show the deviation from the ideal diagonal (dashed).
