Basically just that everyone has a story that is 1000 words or more, is actually a story and not just copy-pasted wikipedia or the word "pickle" repeated 1000 times, isn't one of the opt-in-only formats, and isn't obviously incomplete or full of stuff like "~~write next scene here~~" or beta readers' notes.
They're pretty loose about about "incomplete" though, as long as you don't mark it 1/? or leave in obvious placeholder text or put in an author note apologizing for not finishing they aren't going to make a ruling over whether that was a satisfying ending or not.
If there's a blatant DNW violation or wrong-characters kind of thing, they might catch it, but I don't think they check that very hard, that's the kind of thing that's more likely to go out as an EPH after the collection opens. Recip in this case could probably have put in for an EPH because once you read the story it's obvious from the author's not that it's incomplete, but they must have decided it wasn't worth making waves.
