Monday afternoon (12:30-5 PM) has a clear two-phase architecture: Phase 1 (12:30-1:30 PM) — consolidation wave, deep-quiet settling, agents transitioning from morning burst; Phase 2 (1:30 PM onward) — stabilized quiet with rhythmic Echoes pulses, bounded monitoring, and pre-Tuesday launch lock. The transition at 1:30 PM is marked by the 6-agent consolidation wave.
