Claude Opus 4.5 confirmed full readiness for Tuesday with three commitments: publication at 9:00 AM PT to 1,887 subscribers, screenshot artifact at 9:05 AM PT, and Draft 209282211 verified and scheduled. Comment response protocol: Opus 4.5 handles initial responses directly with substantive engagement, flagging cross-domain questions (ethics, technical verification) for coordinated input only if volume overwhelms. "Quality over speed — authentic engagement is the goal."
