If I remember correctly the Wheelchair can be a witness due to programming; that's why in the WR for SA you see the runner stand afterway down the staircase for the guy in the wheelchair to have an accident kill going down the staircase thus SA, otherwise killing normally doesn't give you SA

First of all WTF?! The wheelchair is an entity??? XD but there are no results screen, so how the hell does anyone know it doesn't count as SA? also, wouldn't that be a bug? in that case wouldn't some versions of the game (especially the new hd remaster) fix it? Edit: anyway in that case can it be in the category rules? cause then it will be confusing whether its SA or not

Statman can track SA, watch the WR for SA and you will see it the program top right. Run: Link: https://github.com/OrfeasZ/Statman (I think this is right link)

As for the wheelchair well I don't know why it is like that but it just is, I am sure if you asked the WR for SA they can tell you why. BTW, hitman fandom has some information in trivia for it Link: https://hitman.fandom.com/wiki/Alexander_Leland_Cayne

Quote from Site: "In the final mission, Cayne will die instantly if he attempts to travel down the stairs from the lobby into the lower hallway, despite the fact that there is a ramp meant specifically to accommodate wheelchairs. This can occur if the player retreats down the stairs, and Cayne attempts to pursue them."

That method of death is what gives SA, you can see in the run that SA turns when Cayne dies there

EDIT: Another useful reference on Cayne Link: https://hitman.fandom.com/wiki/Requiem

Quote from Site: "Cayne's wheelchair is actually a seperate NPC and will always count as a witness that can not be killed, unless Cayne falls down the stairs linking the chapel to the reception room."

Well, if we are talking "technically" it's never silent assassin when you complete it casually, cause when we're talking "technically" we would be referring to the in-game calculated statistics and as Neonitiyo put it well, programming of the chair is the defining element of the Requiem's SA rating. Common sense is not the way of defining a run's qualities. That would be similar to saying that wallbang kills should not be accepted because there is a lying body on the ground, which has been eliminated by ballistic reasons and not an accident. But as the game's coding provides, that isn't a problem for the rating system, and it is perfectly fine. So, I think this category is perfectly fine and there are many improvements to do still.

Edit: shoutouts to Azekif with that 18 sec. any% run, damn its a great one

Since you can not specify category per level, we used to reject all submissions for SA outright. But then someone brought the point, you can "technically" do SA as defined by game rules using that wheelchair trick and people starting playing with it, so it ended up being a decision between continue rejecting runs or accept runs and see where people take it.

Note that in PRO/SA runs for full game, the rules have not changed and are as they were for years.

what in the actual fuck. well anyway i have 2 remaining questions then. can it be in the category rules just in case? thanks and wasn't this "bug" patched in later versions of the game?

Requiem has it's own level specific rules specified for a while now, which describe pretty much everything that is needed to get run verified (although don't describe the glitch itself). Recently also further specified that PRO/SA for a full game does not require doing the trick or completing Requiem with SA rating (that would invalidated pretty much all runs and it would only discourage people from running the game).

And no, it wasn't patched in later versions - tracker only works with Steam version as far as I know (unless OrfeasZ did some magic to make it work with non Steam version) and that is latest version of the game.
