A persistent identifier can stabilise access to an idea without fixing its future relations, giving a concept a durable point of return while allowing it to move across works, media and contexts. The Fifth City Begins Between Disciplines provides the first material test through The Fifth City, where urbanism is formulated as relational infrastructure connecting ecological humanities, civic practice, art and architecture, allowing one proposition to operate across several disciplinary situations while retaining a recognisable conceptual structure · RepairFeedback · https://doi.org/10.5281/zenodo.18681761 · https://antolloveras.blogspot.com/2026/01/the-fifth-city-urbanism-meets.html. A Blanket Can Carry Memory provides the second through The Blanket, which repeatedly enters chairs, walls, bodies and landscapes across the Unstable Installation Series, accumulating memory through use, travel and changing context while remaining identifiable as the same material element · SOCIOPLASTICS-2791 · RegimeMutation · https://antolloveras.blogspot.com/2026/01/the-blanket-portable-memory-across.html. These works gain density across the field through Copos 266 — Oficina Madrid · SOCIOPLASTICS-4515 · https://www.youtube.com/watch?v=jR5sOVX_Jc; the Hola Verde Urbano archive of June 2019 · SOCIOPLASTICS-5446 · https://holaverdeurbano.blogspot.com/2019/06; Expansion into Multiplatform Territory · SOCIOPLASTICS-4234 · https://antolloveras.blogspot.com/2026/05/the-expansion-of-this-territory-into.html; The Contemporary Post-Platform Landscape · SOCIOPLASTICS-5967 · https://lapiezalapieza.blogspot.com/2026/06/in-contemporary-post-platform-landscape.html; Bender, Gebru, McMillan-Major et al. · SOCIOPLASTICS-3470 · https://youtubebreakfast.blogspot.com/2026/05/bender-em-gebru-t-mcmillan-major-and.html; Rhizomatic Nervous System · SOCIOPLASTICS-389 · https://antolloveras.blogspot.com/2026/02/rhizomatic-nervous-system.html; Associative Citation Saturation · SOCIOPLASTICS-1720 · https://otracapa.blogspot.com/2026/02/associative-citation-saturation.html; and The Ephemeral as Foundational · SOCIOPLASTICS-88 · https://freshmuseum.blogspot.com/2026/01/the-ephemeral-as-foundational.html. Across these returns, The Fifth City and The Blanket provide two complementary material tests: one preserves conceptual identity while passing between disciplines, and the other preserves material identity while passing between situations. The surrounding traces extend the same condition through multiplatform circulation, citation, archives and distributed infrastructure, establishing the persistent identifier as a stable return point within a field whose relations remain open to change.
