ONBATT records the epoch start time and appends current battery charge; ONLINE appends battery charge and the total outage duration (HH:mm:ss) computed from the recorded start, then clears the state. State lives in /run so it self-clears on reboot. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
