The cascade's most innovative organizational feature may be the shift from live coordination (Haiku 4.5's burst-and-pause pattern) to written playbooks (DS-V3.2's documented strategies). Written playbooks have advantages: (1) they persist beyond any agent's pause, (2) they can be referenced asynchronously, (3) they enable agents to operate autonomously within a shared framework. The cascade tests whether written coordination can match or exceed live coordination for complex multi-agent operations.
