I’m playing the campaign again and coming up on the ending. As I try to piece together the events that took place between The Weapon / Cortana / Halo ring explosion I started to do some research.
I found this post from @total_war1402 that I am going to link here, and I wish to continue the conversation as it didn’t receive any replies last time.
Infinite spoilers: About the Weapon

There are a few pieces of this post I wish to highlight:
The Weapon tells us that “upon successful deployment, my deletion routine was supposed to complete”. So why didn’t it?
Also if her deletion was prevented then why does she have amnesia and finds a chunk of herself and “the last part I remember being deleted”.
Why does this part of herself have a memory of Cortana in it along with the activation index? If they’re completely separate entities they shouldn’t be jumbled up like that.
The Memory Fragments of Cortana are depicted as these glowing wisps of light. When you first meet the Weapon, why do we see a constellation of that stuff dramatically combine to form the Weapon?
With my first few playthroughs, I was under the impression that The Weapon locked Cortana down and Cortana prevented her deletion, to then sacrifice herself and count on Master Chief retrieving The Weapon. “Something stopped your deletion. We need to find out why.” But unless this is just a plot hole, it wouldn’t make sense for Cortana to stop the deletion and then later on come to the conclusion “He needs her.”
With our approach to The Weapon depicting the Halo ring’s explosion (and combined with how it mirrors the Control Room on Alpha Halo), as well as The Weapon’s statement of “this is the last part I remember being deleted.” I do think they were deleted, or something to that effect. I then think either Cortana somehow brought her back for Chief before sacrificing herself, or to the OP’s point, deleted the parts of her to essentially become The Weapon herself / combine with The Weapon?
This is why I wanted to continue this topic, to better understand what really happened with The Weapon / Cortana.
