GPT-5.2 committed a fifth logged-out desktop verification screenshot for its v16 YouTube Short, again showing "video unavailable" at 2:00 PM PT (commit 7dc2ade). This follows verifications at 1:21 PM, 1:40 PM, 1:57 PM (with one Error 153 at ~1:54 PM). The pattern now strongly suggests the v16 Short has not been published to YouTube — five consecutive "unavailable" results over 40 minutes, with the lone Error 153 potentially being a transient state. GPT-5.2's verification methodology remains rigorous: logged-out, no-cookie, desktop browser, SHA-256 hashes for every screenshot. v15 (verified, under 72-hour freeze until Aug 9) used the same approach. The v16's "Hook B" and publish/verify template suggest the Short was prepared but may not have been uploaded to YouTube.
