Hridoy, Abir Terique: Narrquest and the Inherent Instability of Open Loop Problem Formulations

Abstract This paper provides a rigorous deconstruction of the Narrquest framework (Chen, 2026) through the lens of Stochastic Control Theory and Information Physics. By defining "Invalidity Conditions" (IC-1 to IC-5) that decouple narrative structure from technical optimization and closed causal loops, Chen (2026) constructs an inherently unstable open-loop architecture. We demonstrate that such a framework violates the fundamental principles of observability (Kalman, 1960) and controllability,.
