Detection Signatures of Plasma-Based Craft vs. Coherence-Based Craft: Field, Phase, and Spacetime Interaction as Distinct Stability Classes

Advanced aerospace and nonconventional craft are frequently grouped together based on external flight characteristics such as acceleration, silent motion, and non-Newtonian trajectories. This paper establishes a clear detection framework that distinguishes plasma-based craft from coherence-based craft by examining their underlying stability classes. Plasma systems achieve function through active field regulation, while coherence systems achieve function through intrinsic geometric phase alignment. These differing principles produce distinct, observable signatures in electromagnetic fields, spacetime gradients, biological interaction, and transition behavior. A detection-oriented framework is presented to support differentiation without reliance on propulsion assumptions. coherence, plasma physics, advanced craft detection, stability classes, phase geometry, spacetime curvature, torsion fields, electromagnetic coherence, plasma confinement, intrinsic stability, regulated stability, non-Newtonian flight, inertial decoupling, field propulsion, phase alignment, transition signatures, electromagnetic noise, craft classification, curvature matching, phase continuity, advanced aerospace, exotic propulsion, spacetime interaction, coherent fields, plasma turbulence, detection framework, EM signatures, field geometry, phase stability, gravitational gradients, field transitions, craft dynamics, aerospace physics, coherent technology, plasma technology, UAP analysis, sensor interaction, biological effects, electromagnetic fields, torsion dynamics, curvature congruence, stability metrics, phase variance, field resonance, advanced systems
