`responses` corrupts previous conversations `assistant` item

OK one slightly odd thing you are doing is you are appending a system message using responses after the conversation is well under way. Can you avoid that? 1. system → original system 2. user → original user 3. assistant → your injected assistant 4. system → NEW system (from Responses input) I would expect (and I’m probably not the only one) only one system message and then a series of user and assistant messages. So your pattern is at least non-standard and might not be supported.
