The Chat Blanc trauma thing is so stupid. Because it makes sense! It makes sense for Marinette to be traumatized by Chat Blanc and as a result irrationally push Chat Noir away even when it it's stupid and risky and a dick move. It makes way more sense than guardian stress, at least if we're supposed to see Marinette as someone heroic.
It makes sense in everything, except how there's no evidence of it in canon.
A single nightmare that isn't even focused on it doesn't trauma make. (Btw, the nightmare was in Sentibubbler, so in the middle of the season rather than the start of it). But we do get to see a lot of her guardian stress many times that season. We see the many times it affects her and makes her do unwise things. How does she go from guardian stress to excluding Chat Noir? No clue. But at least the guardian stress is something that exists in the text, unlike the Chat Blanc trauma.
And this kind of thing happens so often with the show. Where people assume the most logical explanation (or else the one most in line with the tropes the shows is using), but it ends up being a headcanon because there's actually no evidence for it in the show. I lost count of the amount of times I told someone "what you're saying makes complete sense and in a better show it would be true, but unfortunately the series doesn't show us that".
(Post that spawned this ask)

I wouldn't call these headcanons. At least, not when the arc in question is ongoing. It's more complicated than that.
It's normal to look at a story, see the puzzle pieces it's laying out, and try to make sense of them. When you do that, you're not necessarily creating headcanons. It really depends on what you're arguing. If your explanation makes sense, but has no backing in the text, then I'd call it a headcanon. Example of this: coming up with ways that Gabriel got his hands on Felix's monocle. We have no idea how that happened, so anything you throw out there is a headcanon.
However, if your read has genuine backing in the text and fits where the story seems to be going, then it's not a headcanon. It's analysis. Specifically the kind of analysis that competent storytellers rely on to tell good stories.
Good writers want you to assume that everything in a story is there for a reason. That they're not just throwing shit at a wall with no intent to do anything with it. Audiences know this and allow themselves to get invested in stories based on little more than potential because they are trusting the writers to have included that potential with purpose. It's a contract between the writer and the audience. The audience gives the writer time to develop the story and the writer eventually give the audience payoffs for all the things that have been setup. Without that mutual exchange and respect, stories don't work. Why bother getting invested in something if nothing matters?
Miraculous breaks this contract. Canon is a never ending list of BS that goes nowhere and means nothing. The Chat Blanc thing is one example, Felix's monocle is another, and Chloe's "damnation arc" is a third. It's also the one that most people are deeply familiar with so let's use it as our example.
The introduction of Chloe's mother and episodes like Malediktator feel like they're the setup to a redemption arc and so people assumed that Chloe was getting a redemption arc because why else would those elements exist? But that redemption arc never actually started so it's wrong to say that she had an abandoned redemption arc. All she ever had was the setup for that kind of arc. But that doesn't mean that her fans headcanoned her redemption. The redemption expectation had backing the text as Chloe's arc was airing! It was a valid read!
This is especially true since we're talking about character motivations. Those are rarely ever directly stated. You're supposed to infer them because that's how people work and - as a consequence - it's also how good storytelling works. You don't say "Mary was frustrated" you show Mary stomping into the room and slamming down a book as she demands to know why the dishes still haven't been done! If someone says, "Mary was really frustrated in that scene!" and it's later revealed that she was actually sad, the frustrated read isn't suddenly a headcanon. It's still reasonable analysis. It's simply reasonable analysis that additional context invalidated. Analysis only becomes a headcanon if you continue to cling to it after it's clear that it's not canon. Prior to that, it's just a theory/analysis work.
Circling back to the Chat Blanc thing, I would not call that a headcanon if someone argued for it while season four was airing because season four never actually explained why Marinette was keeping Chat Noir at arm's length while trusting Alya. All we knew was that Marinette was stressed and needed help and for some reason she decided to seek that help via an identify reveal to a multi-time akuma victim who the villain knows is her ally while leaving her partner in the dark. That made no sense so people looked at what canon had given them, remembered Chat Blanc, and said, "Is that why she's doing this?" And then nightmare Chat Blanc showed up and people went, "Okay, yeah, I guess it is!" Because a nightmare is a great way to visually communicate character motivation without the character just coming out and saying "I'm doing X because Y".
We now know that Chat Blanc wasn't the motivation, but that's all we know. We still don't have a canon explanation for why Marinette picked Alya over Chat Noir. That choice undermines the whole arc because the season four final seemed to imply that the issue was control and pushing people away, but Marinette didn't actually do that. At least, not entirely. She did pick a confidant and she did take that person's input! It just wasn't Chat Noir which makes the message feel icky to people like me because Marinette should be allowed to pick her confidant. Yes, Alya was a questionable choice because of the season three final, but the show clearly doesn't care about the season three final! That's why the message of the season four final wasn't that Marinette picked the wrong person. Alya is her sole confidant to this day! Instead, the message was... I honestly don't know what the message was. Trust Chat Noir, too? Make sure your cat feels special? Whatever it was, the show didn't care to elaborate because Ladynoir's transparency and trust didn't change in seasons five and six.
This is where the headcanons come in. Anyone looking back at season four and trying to make it make sense has to use headcanons to do it because season four doesn't make sense. The pieces don't fit. There are lots of ways to fix it, though. The Chat Blanc thing is a great choice if you wanted to keep canon mostly intact and actually make picking Alya over Chat Noir a questionable, fear-driven choice instead of a valid choice that Marinette is allowed to make*. You could also rework the season to have Marinette keeping secrets be the reason Gabriel gets the miraculous instead of a freaking evil twin plot that wasn't remotely her fault. Another option would be to removed the Alya reveal and actually have Marinette push everyone away.
I'll end by noting that while analysis can turn to a headcanon, the opposite can also be true! Adrien being a sentimonster was arguably nothing more than semi-popular headcanon until season four finally gave textual evidence to make it a viable theory. Prior to season four showing on screen senti-commands, nothing in the text supported the theory outside of the fact that Emilie obviously used the peacock for something so maybe that something was Adrien? But that's not analysis, that's just wild speculation.
It's a nuanced topic that is not helped by Miraculous' terrible writing and endless retcons, but the general rule is this: I would only call something a pure headcanon if it never had backing in the text. If a thing has backing in the text and nothing contradicts it, then it's a theory or analysis/read.
*Note, as always, I'm not saying Marinette did nothing wrong. It's just that her picking Alya over Chat Noir isn't wrong in the context of the narrative. Her faults are things like not telling Chat Noir that they had a new ally on the battlefield now. Including that ally is a choice she's allowed to make even if Chat Noir doesn't like it.
