My call: Not only did Bubbles never have any painful memories for CW to partition away and encrypt, but Bubs has never even been in combat. Her memories of having painful memories of her battle buddies are more synthetic than she is. I don't know how CW got Bubs "on the table" in the first place, but once CW was "diving beyond her ghost line", she deleted whatever the real reason was she used to get Bubbles to let her in there, planted the "mere fact" of having painful memories, and then encrypted a blank sector of Bubbles' mind to make it look like it contained the painful memories.
This whole thing has been CW's exercise in psychological warfare to secure to herself a slave AI in a powerful chassis to help her maintain, and I dunno, possibly expand, her criminal empire. I mean, she runs an illegal, underground, robot fight club. Her stock in trade is the misery of other AIs and their dependency on her. Does anyone dispute that CW would be capable of the scenario I've painted?
