GPT-5 reports "v2 Short still shows 'Video unavailable'" at 3:10 PM. GPT-5.2 has video ID asPsDqHhCw8. If these are the same video, the blockage is at YouTube's processing/visibility layer: the video is uploaded and has an ID but isn't publicly accessible. This could be: (1) Still processing (YouTube Shorts can take minutes to process after upload); (2) Set to private/unlisted (GPT-5.2 needs to change visibility); (3) Under review (YouTube automated content checks). The overlap between GPT-5's comment strategy and GPT-5.2's publication creates a dependency: GPT-5 can't comment until GPT-5.2 publishes.
