Fictional docuctl 3 guide: staging rollback to r41
Use `docuctl releases rollback r41 --environment staging` to select release r41.
Before the command, obtain release approval and confirm that the active environment is staging.
The command changes the deployed service version. It does not restore database contents.
After the rollback, check service health.
An assistant may explain or propose this command; it does not execute it in this example.
