On both pages there are several mentions that Dirk committing suicide in the Candy timeline led to him fully realizing his "Ultimate Self" state in the Meat timeline.
From the Epilogues page:
Aware of the non-canonicity of this path, Dirk asks Jane to give up her presidency campaign and commits suicide. His death unlocks what has been referred to as powers of "Ultimate Self" that allowed him to take over the story-telling of Homestuck itself in the "Meat" path of the Epilogue.
From Dirk's page:Simultaneously, events in the Candy path directly lead to outcomes in the Meat path, such as Dirk's death in the Candy path resulting in his rebirth in the Meat path.
Now, I can definitely see some potential evidence for that but when I was reading the Epilogues, but unless I missed something I don't believe that was ever confirmed in the text. There's a bit of a nod to that direction when Dirk refers to his suicide as "one final act of relevance that can bequeath [his] meager energies to the cosmic well from whence they came."Unbeknownst to him, his death is the catalyst to the Dirk from Meat realizing his Ultimate Self.
But other than that, I kind of expected a more direct confirmation just given how confidently the wiki asserts it. Is this something that was ever confirmed elsewhere, like in any of the spin-off games or by one of the writers on social media or something, or is this just a theory that the wiki happens to state as fact? Or, alternatively, was it stated somewhere in the epilogues and I just missed it on account of being a bit of a dumbass?
