Reproducibility Package for "A Successive-Sample Normalized Increment Functional for Transition Sensitivity in Nonlinear Signals"

This Zenodo record contains the full reproducibility package supporting the manuscript “A Successive-Sample Normalized Increment Functional for Transition Sensitivity in Nonlinear Signals.” Contents include: (i) scripts for each domain test, (ii) raw and derived time series outputs, (iii) computed \mathrm{ZC}_t values and exceedance flags, (iv) run metadata (JSON), (v) publication figures (PDF/PNG), and (vi) summary metrics tables. The package covers benchmark dynamical systems (Lorenz-63, Rössler, Duffing, Kuramoto, logistic map, SIR), observational datasets (NOAA Niño3.4, CALIPSO extinction profile, Kp index, BTC daily close), and robustness validation (FFT phase-randomized surrogates and Gaussian noise stress testing). All runs use the locked functional definition with \epsilon = 10^{-6} and fixed threshold \tau = 0.64 as described in the manuscript.
