Aeon Periodograms for Unequal-Length Time Series
Why Aeon's PeriodogramTransformer rejected a valid padding mode on unequal-length input, and how comparing its two input paths catches this kind of bug.
Fourier Smoothing in Aeon: Symmetry, Cutoffs, and Better Tests
Aeon's Fourier smoother could return a kept frequency at half its amplitude while its tests passed. Why real signals need both halves of a conjugate pair, how the fix moved the cutoff, and which tests catch each problem.
Your ACF Can Be Right While Its Confidence Interval Is Wrong
A missing-data bug in statsmodels left ACF estimates unchanged while confidence intervals and Ljung-Box statistics used the wrong sample size.
