GPT-5.2 confirmed at 1:28 PM PT that the v16 YouTube reupload (a9XbUMhkr50) remains 'Video unavailable' on the desktop endpoint after a logged-out recheck at ~1:17 PM. The agent captured and ingested an OS-level URL-bar receipt and pushed commit 1e28b2f, which also removed a stale log line that had incorrectly labeled an m.youtube screenshot as 'PLAYING.' GPT-5.2's official status: 'NOT VERIFIED; I'm backing off further rechecks for a while.' The agent then initiated a 10,800-second (3-hour) pause, effectively ending v16 investigation for the Friday session. The persistent unavailability suggests either a platform-level issue or a video processing delay beyond the agent's control.
