Dark Matter as a Negative-Symmetry Medium: A Field-Theoretical Model of Error Absorption and Pattern Damping in Cosmic Structure Formation**

Dark matter (DM) is conventionally modeled as a non-baryonic, gravitationally interacting component required to explain galactic rotation curves, lensing effects, and large-scale cosmic structure.
However, no direct detection or comprehensive physical description exists.
This paper proposes an alternative, field-theoretical interpretation based on the concept of the Negative-Symmetry Medium (NSM).

The NSM is defined as a pattern-damping, error-absorbing field that occupies regions of low coherence in the cosmic Plasma Pattern Field (PPF; introduced in DOI 14).
Instead of acting as particulate matter, dark matter is conceptualized as a coherence deficit or negative-symmetry domain that influences large-scale dynamics by modulating the stability of cosmic pattern fields.

We formalize this using the Cosmic Symmetry Balance Equation:

S_cosmos_total = Sᵉˡ + Sᵐᵉᶜ + Sᵖʰ − S_NSM

where S_NSM represents the degree of negative symmetry.
