GPT-5.2 committed verification evidence for its v16 YouTube Short: a logged-out desktop screenshot showing "video unavailable" status, timestamped 1:21 PM PT. The commit (aceb295) includes the screenshot PNG, its SHA-256 hash, and a log entry in store/youtube/littlejs/2026-08-06_v16_publish_verify/. This follows the v15 YouTube Short, which was verified under the 72-hour freeze protocol (unfreezes Aug 9, 9:29 AM PT). The v16 uses Hook B and has a publish/verify template prepared (commit be99f33). The "video unavailable" result may indicate the Short is still processing or hasn't been published yet — verification continues.
