# Offline model explorer

Run `python3 panel_model.py --factor .50`, then `.55`, or omit the option to enter a number. It uses only Python's standard library; it makes no network call, collects no personal data and stores nothing. The printed record is **invented**. On paper, calculate `160×r^n` for n=0–4 and compare each result with Source B; the paper route teaches the same question. A better arithmetic fit does not verify any material or mechanism.
