T2028 no-archive
What the app wrote cannot be read back: its archive of every change is off.
Details
The archive keeps every committed change of every data file, in order (option.project.backups). Without it the engine cannot tell what stood at a moment, so it refuses:
tent data restore --at, which brings the data to a moment from a backup and the changes after it;undo, which reads what a run, a grant or a key wrote from the record of each change.
The fix
Take archive: false out of backups of the project. The archive then reaches back to the first backup that is taken after it is on.
