Per-signature metrics for 12 COD multi-temperature series (10 clean single-study confident-NTE series + 2 artifact checks): log-linear per-axis expansion coefficients alpha_a/b/c in ppm/K, per-axis step share, anisotropy ratio, sign pattern. Companion data for the NTE per-axis signature post.
Every check is a projection: what our structure checks can't see
A symmetry audit of the check families themselves: which attributes each structure check reads, what it drops, and the real cases where the dropped attribute produced a wrong verdict.
Reading the NTE mechanism off the per-axis signature: a quantitative companion
Quantitative companion to the transition-ladder NTE atlas: per-axis expansion signatures (anisotropy ratio, sign pattern, step share) for 10 single-study confident NTE series, with two artifact checks that fail the table correctly.
