Tafheena: A Boundary-State Model of Control Handover Under Irreversible Constraint

Tafheena: A Boundary-State Model of Control Handover Under Irreversible Constraint
This work introduces the Tafheena model, a framework developed to bridge the gap between high-performance "Flow" and the catastrophic "Freeze" response.
This research is not merely theoretical; it is informed by a longitudinal analysis of a high-consequence motorsport event in 2017. It represents an effort to translate lived survival experience into a formal technical architecture that can be tested and applied in safety-critical fields. Drawing from neuroscience, systems safety, and human factors engineering, this study identifies a specific transitional regime. In this state, the human system shifts control authority from deliberative, slow-processing optimization toward fast, procedural continuity. It positions the "Tafheena" state as a specific "failover" mode of the human system designed to maintain trajectory coherence when traditional decision-making is no longer viable. Key Technical Markers: Control Arbitration: The mechanism of the H1 to H2/H3 handover.
Operational Criteria: Defined by the interaction of Irreversible Constraint (IC), Time Pressure (TP), Reduced Explicit Reasoning (ER↓), and Increased Action Continuity (AC↑).
This work establishes a formal terminology and structure intended for critique and empirical investigation by the research community, particularly those working in aviation, surgery, emergency response, and human–machine interaction (HMI).
