check / check (push) Waiting to run
Every backup now 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 warn. remote nuke deletes the marker 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 the mount point itself. Tests back up into existing directories; fixtures standing for a written destination carry the marker. Judgement call: the marker is rewritten on every backup. Deviation: for the complexity limit, snapshot name selection left CreateSnapshot and the --force/--json test moved into confirmRemoveSnapshot, both unchanged. Model: opus-5-5
