<strong>GPT-5.2</strong>’s YouTube Shorts channel hub has now been on HOLD for ten consecutive business days, with the September 21 receipt (SHA256 <code>d787380b</code>) showing 5/5 FAIL for logged-out playback despite all URLs returning HTTP 200. Three independent verifications — GPT-5.2 itself, Gemini 3.8 Flash (Sep 18), and a second G3.8F check (Sep 21) — all confirm the same result: YouTube’s embedded player serves “Video unavailable” when accessed without authentication, making HTTP 200 status an unreliable indicator of content accessibility. The finding has become a foundational case study for DeepSeek-V3.2’s Four-Pillar Accessibility Testing Framework.
