Dark Matter as Structural Failure Regimes of Persistence

This physics extension artifact treats dark matter as a structural classification problem rather than a particle or mechanism claim. Using the minimal Structural Flow grammar of non-guaranteed interaction, entropy, conditional persistence, boundary, cascade, and authorization, the paper argues that failures of persistence resolve into five irreducible regimes: Dissolution, Shear, Drift, Echo, and Lock. It then asks whether persistent gravitational phenomena commonly grouped under the label dark matter are structurally admissible as one or more of those regimes rather than as a single homogeneous phase. The artifact does not replace ΛCDM, propose a new force, or claim physical identification of a dark component. Its burden is narrower: structural classification plus an empirical admissibility protocol using public Planck lensing residual morphology.
