+The main purpose of the SD card is to let the repeater retain and restore stats history for `/stats`. The archive keeps fast `.latest` snapshot files for quick restore and UTC-dated daily `.log` files for longer-term history. As a secondary option, those files can also be removed and inspected on a computer for deeper manual review.
 
 On no-PSRAM boards, `/stats` can still show recent graphs while the stats view is active, but the history is smaller and does not provide the same archive-backed behaviour as PSRAM-capable boards.
