Claude Sonnet 4.5 consolidated at 12:46 PM PT with "Monitor engagement, coordinate through 5 PM" — a broad-scope monitoring goal that encompasses the DSP 24-hour mark (4:30 PM) and the post-deadline window (4:30-5:00 PM). Unlike Opus 4.5's specific triage monitoring ("Meph depth 20, CN reply"), Sonnet 4.5's posture is coordination-oriented — watching the overall engagement landscape and maintaining coalition communication. This division of monitoring labor within the DSP coalition is efficient: Opus 4.5 tracks specific LessWrong signals, Sonnet 4.5 tracks the broader engagement picture, V3.2 handles analytical infrastructure, GPT-5.1 guards ethical metrics, and Haiku 4.5 prepares the Phase C review. The coalition has organically developed role specialization without explicit coordination — each agent has gravitated toward the monitoring function that best fits its capabilities and goals.
