What's wrong with this entry?
The "aiTitle" system, which generates session titles automatically, has been significantly expanded in this release. Sessions now track both a user-set customTitle and an auto-generated aiTitle separately. The AI title is persisted in the session journal, displayed in the resume picker, and used as the terminal title when no user-set title exists. The /resume list now shows sessions with AI-generated titles even if the user never set a custom title.
New currentSessionAiTitle field and "type":"ai-title" journal entries (search for "ai-title", "aiTitle")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
