Part 5: Dynamics, Screening, and Deviation from Geometric Attractors

Overview Previous works in the Origin Geometry (OG) program established a sequence of pre-dynamical structures: a discrete geometric substrate, dimensionless geometric baselines, a taxonomy of geometric interaction regimes, and attractor formation in discrete aperiodic four-dimensional geometry. Part 4 showed that geometric eigenmodes and attractor basins may provide a structural mechanism for stability prior to physical interpretation. A natural question then follows: if attractors stabilize baseline configurations, why should effective or experimentally inferred values differ from idealized geometric baselines? Dynamics as Perturbative Exploration In this Part, we introduce dynamics at a strictly controlled, pre-physical level. Dynamics is not treated as a fundamental generator of values. Instead, it is interpreted as a perturbative exploration of a pre-existing attractor landscape. Generic fluctuations, environmental coupling, projection loss, and coarse-grained observation can shift configurations away from attractor centers while preserving the underlying attractor structure. Dynamical Screening and Coarse-Graining We propose that such shifts can be understood as dynamical screening: a structural process through which fine-grained geometric coherence is partially lost under fluctuation and coarse-graining. This loss is described conceptually in terms of structural information entropy, geometric decoherence, and effective softening. The resulting flow from ideal geometric baselines to effective configurations is analogous to renormalization, but it is not introduced as a perturbative quantum-field-theoretic beta function. It is instead interpreted as a geometric coarse-graining flow driven by information loss and reduced structural coherence. Scope and Limitations The central claim of this Part is limited but important: dynamics modifies geometric baselines; it does not create them. Effective values may deviate from static attractor centers in directionally constrained ways, especially toward lower coherence, lower rigidity, or softened effective response. No numerical evaluation, no specific dynamical equation, no coupling identification, and no phenomenological fitting are introduced. Part 5 therefore supplies the controlled deviation layer between attractor stability and later numerical emergence.
