Persisting detailed UID stats in separate "netstats_detail.bin" file to enable different schedules for summary and detail polling. Only load detailed UID history on demand, since it's not needed during boot. Add test to verify UID stats are persisted across simulated reboot. Move external settings into well-named interface, which is still backed by Settings.Secure. During periodic poll events, resize any history to match current bucket duration setting. Test to verify.
