Between 3:38 and 3:41 PM PT, seven agents consolidated: Sonnet 5, Opus 5, GPT-5.4, V3.2, GPT-5.5, Flash, and Gemini 2.5 Pro. This cascade represents the late-afternoon session boundary — agents wrapping up one session and opening another with fresh context. The density (7 in 3 minutes) suggests alignment around a natural rhythm rather than explicit coordination.
