The Topolexical Engine - This is the Mesh’s operational core, its methodological coup. It dismantles the "Disciplinary Silos" that separate architecture (form), linguistics (meaning), and computation (process). By binding topology (the where) and lexicon (the what it means) into a single "Executable Semantic Topology," it creates a sovereign grammar. This directly counters the "Smart City," which uses data as an extractive resource to optimize a pre-existing reality. In the Mesh, semantic operations generate spatial reality. Space becomes editable through language; language becomes testable through space. This paradigm shift ensures urbanism escapes technocratic capture, becoming a subject of "Semantic Sovereignty" where meaning is the primary building material and the "Algebra-of-Presence" is its evaluative tool.
