    # so that we reconcile both newly generated keys and any pre-existing keys with
    # incorrect ownership/mode in one place.
    #
    # This primarily protects against setups where `become_user` is effectively not
    # honored (for example due to inventory misconfiguration such as `ansible_become=false`),
    # which can lead to host-side key generation creating root-owned files.
