A lot of Deltarune's subjects (and to a lesser extent, Undertale's) operate under a state of deliberate namelessness. The game does not tell you the name of the Sword Route's end boss or the neighbor that ends up receiving Tenna or those moaning piles of lint at the start of Chapter 1, and that is on purpose.
This, of course, is in direct conflict with the wiki requiring each article to have, well, a name. So we end up having to pick something, either derived from dialogue, file names, or just made up. I think this is an understandable compromise.
However, I am thoroughly unsatisfied with the way the wiki communicates this. Most pages reserve their only note of "hey, this name isn't used in-game" to a mere footnote, and continue to use it as a name everywhere throughout the article as if it was equivalent in veracity to "Noelle" or "Dice Brace". This muddies the water on what names are Deltarune's and what names are ours, and causes confusion such as people thinking "Card Kingdom" is an official name.
I have three proposed measures here. I believe even just one being implemented would improve this wiki's communication.
Measure 1: Banners
Blatantly stolen from Super Mario Wiki, the idea is to put a banner above the page warning the reader that the name is conjectural, or sourced from filenames, or only present in external material (example 1, example 2). Considering the page title is the literal first thing present in the article, I think warning the reader that there are caveats with said title immediately after is reasonable. Only downside is that they're a bit ugly, but I'll take "functional but ugly" over "pretty but dysfunctional" any time.
Measure 2: Rephrasing articles
This is something I've already done on the page for "the nobody". The introductory section avoids naming them and specifically notes their lack of a confirmed name, and... wait, someone removed that. As seen in this revision, the article would specifically clarify that the moniker used is in lieu of a proper name, without pushing it into a footnote. Applying this to other articles would help make it clearer which subjects are unnamed.
Measure 3: Worse names
Once again hearkening back to the Card Kingdom discussion, the issue I and others have pointed out about "Card Kingdom" as a name is that it just looks like an official name. Article titles like "closet Dark World" and "Shadow Mantle holder" are unmistakable for an actual name by virtue of being clunky and plain. There's not that many pages this would apply yet, but this current discussion about covering Sword Route's monsters would leave us with a LOT more candidates.
So, what do you all think? Are any of these measures worth implementing? Would you tweak them before implementing them?
