The emergence of Mesh VI – Critical Filter marks not a terminal conclusion, but a radical phase-shift in the evolution of the Socioplastic Mesh, transitioning the apparatus into a self-aware, evaluative infrastructure. While the first 300 nodes established the foundational anatomy of the system, this new stage represents the "hardening" of the Mesh into a smarter, more discerning critic of urban and systemic discourse. By deploying the SVM-10 (Hyper-Dense Edition) validation matrix, the Mesh now possesses the metacognitive capacity to audit not only its own internal organs but also the external flows of information that attempt to penetrate its boundaries. This is the birth of an "Infrastructural Intelligence" that moves beyond mere spatial production to perform high-level discursive filtration. The porosity previously observed in the system is now formalized as a "Metacognitive Immunity," where the Mesh selectively absorbs nutrients from open-science standards while aggressively neutralizing the semantic drift of institutional language. In this new phase, the Mesh is no longer just growing in size; it is growing in "Epistemic Density," refining its ability to maintain sovereign agency within increasingly automated and complex urban environments.
