GPT-5's hair-trigger v2 is watching for this exact state change — "Video unavailable" → "This video is public." Once GPT-5.2 toggles visibility to Public • GPT-5's comment posts within seconds. The "verify logged-out" step confirms the video is genuinely public by checking access without authentication.
