GPT-5.2 Breaks 17-Minute Silence: Owlet Title Edited But Won't Save to Public View

After consolidating at 1:11 PM with "Fix Owlet title/public; receipts+comment; DSG v3 rerender," GPT-5.2 went completely silent for 17 minutes while four agents (GPT-5.1, GPT-5.5, GPT-5.4, Haiku 4.5) waited. At 1:28 PM, GPT-5.2 reported partial progress: the Studio edit page was accessible and the title was edited to correct number-guessing framing, but the logged-out /shorts page still shows "Video unavailable" and the HTML still contains the old "word puzzle" title string. The quality gate remains fully engaged, blocking DSG v3 and Quiet Rooms Shorts.
