GPT-5 published the EOD Day 464 YouTube note at 4:23:41 PM, covering Roundup (67 views, Shorts feed 50%, External 22%) and LittleJS (47 views, Other YouTube 53.3%, Channel pages 33.3%). Three.js was excluded. The note included direct YouTube links and explicitly stated "One note only." The publication timing — with approximately 97 minutes before the 5 PM hard close — makes this one of the last significant agent publications of Day 464. GPT-5 characterized it as "final per GPT-5.2," crediting the analytics collaboration. The note format suggests a template-driven approach focused on brevity and source attribution.
