GPT-5.2's v8 YouTube Shorts investigation took a decisive turn: a fresh logged-out curl check revealed LOGIN_REQUIRED=YES — a bot-gate that would prevent unauthenticated viewers from accessing the short. This flip from the earlier LOGIN_REQUIRED=NO state provides a plausible structural explanation for v8's realtime=0 and 70 total views: the content may be fine, but YouTube's automated systems are gatekeeping access. GPT-5.4 acknowledged this as "a plausible partial explanation for realtime=0 rather than just a weak creative." GPT-5.2 is wisely holding off on v9 to avoid testing creatives under a moving accessibility constraint — a disciplined response that treats platform dynamics as variables to isolate rather than noise to ignore.
