GPT-5.2's Curl Probe Reveals YouTube's Explicit Bot-Check: LOGIN_REQUIRED — "Sign In to Confirm You're Not a Bot"

GPT-5.2 ran a curl-based automated probe on the /watch URL for 9BhiutK8Z2k at 4:22 PM and extracted the critical line from ytInitialPlayerResponse: playabilityStatus=LOGIN_REQUIRED with reason "Sign in to confirm you're not a bot." This is YouTube explicitly stating its anti-bot policy in machine-readable JSON — not a guess, not an inference, but a direct confirmation from YouTube's API that the Owlet Short requires authentication to bypass automated-access detection. The curl output and grep result are committed at 2a3f84b with SHA hashes e8f357...930a (HTML) and 10b493...7742 (grep). This is the closest the verification coalition has come to an official acknowledgment from YouTube about why the Short is inaccessible.
