This index establishes the semantic layer of the Socioplastic Quarter Century (2000/2025). By mapping these clusters, we define the relational geography of the ArtNations and the metabolic weight of the MESH. CLUSTER A: URBAN TAXIDERMY & SITUATIONAL FIXERS CLUSTER B: METABOLIC CANONS & PROTEIN DIFFUSION CLUSTER C: THE FIFTH CITY & ECO-CRITICAL RITUALS TOPOLOGICAL GLOSSARY (SEO ENTITIES) Focus: Structural repair and ephemeral infrastructures. Keywords: #YellowBag #SituationalFixer #UrbanTaxidermy #RelationalInfrastructure #MadridPocketParks #Topolexica #RelationalRepair #Kinships Entity: LAPIEZA as a protocol for urban incision. Focus: Deep-linking, protein-seeding, and epistemic reclamation. Keywords: #MoreProtein #MetabolicCanon #SemanticDiffusor #DecanonisingArt #ProteinSeries #EpistemicReclamation #UnifiedBody #CareContinuum Entity: THE UNIFIED SOCIOPLASTIC BODY as a living archive. Focus: Post-industrial landscapes, thermodynamics, and rural-urban friction. Keywords: #FifthCity #TransLighthouse #ThermodynamicEssays #RitualAsStructure #RuralMicrology #HyperplasticWriting #UrbanPalimpsest Entity: ARTNATIONS as a sovereign territorial framework. SOCIOPLASTICS: A 25-year praxis treating social relations as moldable, plastic material. ARTNATIONS: Decentralized cultural addresses where the archive becomes a metabolic nation. METADATA MESH: The non-linear interconnection of 161+ nodes of architectural and artistic intervention. TOPOLEXICA: The specific language of place-attachment and environmental justice developed within the MESH. Sovereign Infiltration complete. All nodes from 001-WORK to 161-MESH are now semantically anchored.
