- Replace vague 'System Recovered' message with 'Configuration Rolled Back'
and actionable text describing the rollback outcome
- Replace 'Manual Intervention Required' with 'Rollback Unsuccessful' and
specific instructions: check jail.d/{name}.local, fix manually, restart
- Add test_activate_jail_rollback_deletes_file_when_no_prior_local to cover
rollback path when no .local file existed before activation
- Mark all three tasks complete in Tasks.md
