A backup counted as deleted every file in the local index under the source path that the walk did not find. That took in files the snapshot excludes but another snapshot backs up, and files removed long ago, which every later backup, and the first backup of another name over the same path, reported as deleted again. The backup now looks up the most recent completed snapshot of the same name and counts only the files it lists that the walk did not find and that are not excluded. The snapshots row stores no deleted figure; only the backup's output changes. Model: opus-5-5
