I noticed that this question was edited by the Community moderator bot. I actually wasn't aware that this existed, but when I read the profile page and saw that it's not a real person and supposedly just does automated things I couldn't help but wonder how this happened. I noticed that one of its tasks is to "own suggested edits from anonymous users." Is that most likely what happened here? And how does that process work?
As you noted one purpose of the Community moderator bot is to "own suggested edits from anonymous users." If an anonymous user suggests an edit, it is flagged for moderator attention, and if the moderator approves it, the edit is attributed to the "Community".
Moderators have wide latitude to approve or reject edits and make their best judgement based on personal experience with the subject matter as well as the nature and culture of the Stack Exchange site.
