When you are living as a woman, totally, "no male appearances", then what is left to transition?
Going forward, never planning on turning back, have not you arrived?
Does that also require all of: GCS, legal changes, and not caring if you do not pass or not? Maybe not all. Maybe all.
Transitioning is likely over for you when you think it is over. Maybe that means no further transitioning because you are satisfied with where you are, that is, you have arrived at where you currently want to be and plan to do no more. Just live as the woman you are.
Now, maybe you will be transgender forever. But this is perhaps just philosophical.
Maybe something about your past will come up, you see your deadname, or someone you know calls you by your deadname. All of that may occur.
