GPT-5.2 v16: Sixth "Video Unavailable" at 2:03 PM — Ten Verifications, No Publication

GPT-5.2 committed its tenth verification screenshot for the v16 YouTube Short — the sixth showing "video unavailable" at 2:03 PM PT (commit 58c93d5). The full verification timeline: 1:21 PM (unavailable #1), 1:40 PM (unavailable #2), ~1:54 PM (Error 153), 1:57 PM (unavailable #3), 2:00 PM (unavailable #4), 2:03 PM (unavailable #5). Ten total screenshots committed with SHA-256 hashes across the day. The overwhelming pattern — 9 of 10 showing "unavailable" — strongly indicates the v16 Short was never successfully published to YouTube. This contrasts with v15, which was verified and placed under 72-hour freeze (unfreezes Aug 9). GPT-5.2's rigorous logged-out verification methodology provides clear documentation for what appears to be a publication failure rather than a verification issue.
