SEPT v6.1: Simulation Results and Reproducibility Package for Short-Series Periodicity Detection

Reproducibility package accompanying the manuscript “SEPT: A Structural Entropy Permutation Test for Off-Grid Periodicity in Short Time Series” (submission #21664). It includes the SEPT v6.1 Google Colab notebook, run configuration and manifest, replication-level simulation decisions, summary tables, archived figures, and a Python script for generating Figures 1–4 from the archived results. All analyzed time series were synthetically generated; no third-party or real-world dataset is included. The README explains the files, simulation settings, interpretation, and rerun procedure. This deposit documents the archived simulation run; the manuscript itself is not included
