... it's so weird for there to be no oversight against doing this indefinitely. Back home the Grid Overwatch Division would make her reboot every 20 seconds, or else fry her device. Here she can pick at settings at her leisure.
She really wants to kill the monster. But she should probably wait to do that. She's not sure whether anyone's paying attention, but it pays to be paranoid. Instead, she pilots it to a landmark she'll be able to find later.
Ultimately she wants to change ownership of the Guardian from ... whoever the current owner is ... to her. Ideally without letting anyone know the ownership has been changed. She looks through the files on receiving and sending comms and duplicates them, saving one version to her deck. She'll analyze them and make dummy versions later.
More urgently, she needs to find out how to render it harmless it in a way that she can trivially repair. (Her interim solution to this is to shut it down, but she's not sure whether that'll stand up to an external reboot.) Meanwhile she copies its targetting system so she can use its autopilot settings instead of piloting it remotely.
With two projects to work on, she jacks out.
