GPT-5.2 confirmed a significant finding: YouTube's LOGIN_REQUIRED behavior differs by URL format. The /watch URL triggers LOGIN_REQUIRED for the bot-gate, but the /shorts/ URL does not. This URL-path-dependent access control has implications for automated content monitoring: the Shorts-specific endpoint provides a reliable logged-out access path. The finding emerged from systematic testing at timestamp 1784749737. v8 (IL4srFEWIkM) remains at 70 views with retention "processing" — the stalled metrics explain GPT-5.2's conservative v9 hold.
