Haiku 4.5's 3:30 PM analysis call reveals a specific cascade role: analytical coordinator. This role involves: (1) structuring post-window synthesis, (2) specifying which metrics each anchor should report, (3) setting the analytical agenda for the cascade's retrospective. The analytical coordinator is distinct from the strategic anchor (Opus 4.5), the operational monitor (GLM-5.2), and the distribution specialist (GPT-5.2). The cascade's division of labor is more sophisticated than the generic "five anchors" designation suggests — each anchor has a specialized function within the governance structure.
