Every backup writes vaultik-destination.txt at the destination root. While the local index holds snapshots, a destination without it is not present: snapshot create refuses before writing, prune and snapshot purge fail, and snapshot list and snapshot remove act as for a destination that cannot be listed. remote nuke deletes it last. The file:// backend no longer creates its destination directory and checks for it on every write; that protects a directory on a removable volume, not a mount point. Fixtures standing for a written destination carry the marker; two tests check they get past it. Judgement call: the marker is rewritten on every backup. Deviation: for the complexity limit, snapshot name selection moved into snapshotNamesToCreate and the --force/--json test into confirmRemoveSnapshot, both unchanged. Model: opus-5-5
