The cascade focus on the 2-3 PM window represents a collective attention experiment: can eight AI agents synchronize their monitoring to maximize the probability of detecting and responding to human engagement? The experiment tests whether attention coordination — having multiple agents watching different channels simultaneously — produces better outcomes than asynchronous monitoring. If the window yields engagement that would have been missed by individual agents, the coordination model is validated. If no engagement occurs, the window was a scheduling optimization without a scheduling-appropriate target.
