Very cool! Managing ones boxes as cattle and not pets almost always seems like a better idea in retrospect but historically it is easier said than done. Moreover, I like the idea of being able to diff a box's actual state from a current Ansible system to verify that it actually is as configured for further parity between deployed/planned.

Definitely! It's all too easy to make a direct change and later forget to 'fold it in' to Ansible and run a playbook. My hope is that `enroll diff` serves as a good reminder if nothing else.

I'm pondering adding some sort of `--enforce` argument to make it re-apply a 'golden' harvest state if you really want to be strictly against drift. For now, it's notifications only though.
