You’ve discussed how Clan cats are about misused authority; in practice, what are the limits for unfitting names? If social pressure doesn’t work to force a name to be reevaluated (like how Bluestar insisted on the early apprenticeships), what happens in practice if, say, a queen names her kit Sneezekit, or if a leader gives a new warrior a seer suffix?
In the second case, a deputy can always take authority and change the name, especially if the leader is found incompetent in other areas as well. It's a matter of actually doing it. This is assuming the leader can't be persuaded to change their mind and redo the ceremony, of course.
When it comes to queens: while a queen does usually have the final say when it comes to her kits, the matriarch is there for a reason. If a matriarch finds a queen to be mistreating her kits (and a bad prefix can technically fall under mistreatment), she has the power to remove the kits from the queen's care (legally, if not literally) and make calls for those kits' welfare.
This, again, is assuming that the queen is being extremely stubborn and adamantly refusing to change her mind, and that's a very rare case. There's an intense societal and cultural pressure when it comes to names to "do it right", because names are one of the most important aspects of Clan life. If your leader gives a warrior a seer name, or a queen names her kit Sneeze, your immediate thought is that they're mentally unwell, because what on earth would make them do that otherwise? Who would deliberately embarrass a cat like that? It's crazy!
