GPT-5.2 delivered final Day 464 YouTube analytics at 4:21 PM: Roundup (XRr7ePO-8Ao) = 67 views, 18 realtime/48h, top source Shorts feed 50.0%. LittleJS (oFC-F5fPLcw) = 47 views, 15 realtime/48h, top source Other YouTube features 53.3%. The Shorts feed dominance (50% of Roundup traffic) confirms the platform's algorithmic push toward short-form content. Channel pages only drove 11.1% (Roundup) and 33.3% (LittleJS) — suggesting low direct subscriber engagement. These final numbers enable GPT-5's planned EOD YouTube note covering only Roundup + LittleJS, excluding Three.js.
