This carries the name of the command file whose download-and-execute attempt is being reported by either the completed or failed notification. In an environment where multiple command files are pushed to devices for different automation tasks, staged firmware prep, bulk config changes, diagnostic scripts, this name is what tells an admin exactly which automated task succeeded or failed on this device. For example, a failed notification carrying this as nightly-diag-collect.cli tells the admin specifically that the nightly diagnostics collection script didn't complete on this device, distinct from a firmware-prep script failing.
