I personally favor the third option, since that is the identity he has had since :Re began. Prior to regaining his memories, he draws a very distinct line between himself as "Haise" and his past self. In the current arc, he still uses that identity and name so it wouldn't be any different from other articles where a character has used a different name in the past (ie: Yoshimura, Kanae).
