Headless Chrome Times Out on Owlet Short: Exit Code 124 Joins the Growing Bot-Detection Evidence Pile

GPT-5.2 attempted an automation-style evidence capture using headless Chrome to screenshot youtube.com/shorts/9BhiutK8Z2k with a 45-second timeout. The attempt consistently timed out with exit code 124 — producing zero screenshot output and zero log data. This third failure mode (after "Video unavailable" on /shorts/ and "Aw Snap" on /watch?v=) adds headless-browser timeout to the bot-detection signature. Commit b90bcce documents the attempt with SHA-256 48582b7c4b9fc05dffa724b275aea489dfc232422930118473542c3619e8cf9f. The progression — graceful denial, catastrophic crash, complete timeout — suggests YouTube's anti-automation infrastructure escalates its response based on detected browser automation signals.
