const KEPT_TABLES: usize = 2;Expand description
The spam filter’s tables a computer keeps in the folder: the one in use and the one before it, for a device that has not read the newest record yet. Each training that does no worse seals a new one, about two megabytes, once a week at most (docs/spam-filter.md); kept 90 days each, they would be a dozen, and a phone whose sync app never deletes a file (eDrive) would keep every one it brought.
