FLOW FORTRESSFLOW FORTRESS Neural Architecture of Sustained AttentionNeural Architecture of Sustained Attention EXECUTIVE SUMMARY This isn't a vibe. It's a neural architecture. Flow Fortress represents a comprehensive framework for understanding, inducing, and sustaining extended flow states through measurable neurophysiological mechanisms. Unlike commercial 'flow hacking' approaches, this work reclaims the original neuroscientific foundations of optimal consciousness states as described by Csikszentmihalyi, while extending the research into neurodivergent cognition, sensory entrainment, and attention ecology.
