Might repeat myself a bit, sorry in advance for the scroll.
There are a few options we have on the table I feel, personally.
- Gardening SAM to use 1girl and keep them separate. This leaves the chartag still heavily prone to mistags as 1other.
- Recategorising SAM to general. This would be more accurate however there aren't enough non-Firefly powersuit posts to justify this major change in thought and I think it would cause more of a headache for our users and admins to go this route.
- Leave the tags separate and continue to use 1other. Although it is inaccurate, the current dichotomy is more searchable to the average user.
- Furthermore, any posts like the example (SAM and Robin) should not be tagged as yuri, even if that is correct.
In the case of Firefly and SAM, our SAM chartag refers to Firefly's powersuit. Any further changes to this chartag for correctness at this point becomes a mess when it further expects understanding of the game material, which we should not expect from Danbooru users. That's why I'm a little torn between whether to consider the correctness or the searchability.
Enough time has passed with the completion of the story, release of the character and leaks that it is no longer an obscure secret that SAM is Firefly even to those who don't know a lick of the game's lore, so I personally do not feel the ambiguity of the two's identities is a relevant talking point. The only confusion it could bring to Danbooru is the continued inconsistent tagging that we should still strive to sort out at some point. If these were tagged correctly and fixed ASAP, there would be no confusion even to our userbase here on Danbooru.
Part of the confusion here is existing precedent (a la Samus and Sentai characters brought up earlier) and the continued inconsistent tagging. I noticed that there was the point of "looking the same". This would be a deviation from precedent if the implication were to be accepted since Firefly is not visible once SAM is active, however the other angle to consider is searchability and it is generally widely known right now that the two are the same for anyone who is clearly looking for Honkai: Star Rail posts. I think searchability and widespread knowledge has more weight and validity in getting this implication done than the current precedent of costume chartags where a cursory glance shows yes they are still very much the same person with just different hair colours/outfit.
For precedent's sake as well: we have Kakavasha and Yingxing chartags for Aventurine and Blade respectively as earlier points in their lives. These are more obvious than SAM with a simple glance but we still did not imply them until enough posts and time had passed. The scenario is very similar, and the current post makeup should also further allude to there being some similarity (particularly, whenever Firefly is transforming but is not tagged as SAM.
Circular devil's advocate: as much as I keep talking about searchability, blue users are still beholden to two tags like res users are to the modqueue. This implication may potentially force them to use up a tag search to filter out the powersuit. That being said, there isn't enough SAM that gets posted in comparison to Firefly. I feel that users can just ignore those posts during their search, or may not even come across them frequently enough to justify their separation. Now that I also corrected my knowledge of the implication, it would also still allow users solely looking for the powersuit to be able to find it sort of without Firefly. Hell, we never even tag any of her henshins with SAM (or maybe we have in some off-hand circumstances, I haven't checked the query).
