What it Means to be Hydro | Genshin Impact theory 

And if I'm not mistaken, she even turned down having a loophole as well. She decided that even a loophole was something she could not use either.

Thank you. There is 100% some overlap in the broad description of many characters, such as Chongyun fitting Pyro (long line of exorcists) and Hu Tao fitting Hydro (duty to protect the balance). However, when looking into the specifics, a more definitive motivation can be found. (Overcoming excessive yang energy and inherited dream, respectively)

I agree! From my experience with writing, defining a character’s motives so clearly that they don’t allow for overlap with other ideals/themes is insanely challenging-as our world is such a complex and dynamic thing. To strictly define a human’s identity is a Sisyphusian task, so especially when a storyteller defines their character by showing us how they interact with their world, it can be hard to see the character as the storyteller sees them. To me, considering how little screen time and the variety of interaction in Genshin’s story, the amount of depth and subtle definition they’re able to provide is admirable. And I enjoyed this analysis, because regardless of how accurate it was, this creator’s perspective helped me see the characters in a deeper and new light!

My apologies. A code is a strict set of rules one follows. For Mona, it's the rules of astrology her master taught her. For Childe, it's his training to grow stronger. For Xingqiu, it's Guhua. And for Neuvillette, it's the law, which is fun because one definition of 'code' is "A systematic collection of laws or regulations."

Will Sigewinne count as duty because she has a duty of being a nurse in a fortress?

As she hasn't been released, I cannot read her story yet. Once she is, I'll likely pin a comment explaining it. However, I would guess it has to do with her healing anybody no matter who they are or why they're in the Fortress of Meropide.
