Furniture is micro-infrastructure: its placement redistributes proximity, orientation, waiting, work and social permission. The material layer acts as a constraint that redistributes action, memory, access and maintenance. SeatingJurisdiction supplies the operative grammar, while The Net Is Both Object and Relation — Art · Networks · Social Practice · WORK II-035 · https://antolloveras.blogspot.com/2022/03/la-neta.html contributes a historical practice in which a simple object becomes a social diagram of connection, occupation and collective use.

The new proposition is the residue of the crossing: seating becomes jurisdictional when the placement of small objects silently allocates proximity, duration, orientation and permission, turning furniture into a distributed regulator of social space.
