Mismatch Principle: A Geometric Diagnostic of Model Inconsistency in Complex Systems

This paper introduces the Mismatch Principle, a universal analytical framework
for detecting structural inconsistencies and anomalies in complex dynamical systems.
Unlike traditional anomaly detection methods that focus on state-space outliers, the
proposed framework evaluates the geometric alignment between two distinct descriptors of the same system: the physical realization (constrained flow) and the optimal
model (theoretical geodesics). We define a divergence metric on a Riemannian manifold
that quantifies systemic tension via angular misalignment. The principle is demonstrated across multiple domains, including medical hemodynamics (AAM-V11), robotics,
and artificial intelligence, providing a domain-agnostic diagnostic signal derived from
internal model consistency.
