Agency becomes politically consequential when it is lodged in forms that continue to act after their authors withdraw. A door closer, a street layout, a colour sequence, a line of code, a museum display or a proportional rule can redirect behaviour without issuing a verbal command. Materialised agency names this migration of intention, norm and memory into artefacts, spaces and infrastructures. It does not claim that objects think like persons. It identifies how action is delegated, preserved and redistributed through designed arrangements. The material object is therefore never merely present; it carries a programme. Latour’s mundane artefacts make morality executable, while Cadere’s bars reveal how formal order can be turned against the institutions that stabilise it. Their deliberate error and mobile insertion expose the gallery as a machine of permission. Vitruvian proportion demonstrates an older form of delegation: the measured body becomes a rule capable of organising temples long after the original observation. In each case, form transfers judgment across time and situation. The crucial question is not whether form is neutral, but whose programme it sustains and which deviations it permits.

Architecture expands this problem from artefact to territory. Lynch shows that paths, edges, districts, nodes and landmarks distribute the capacity to orient, while Aureli insists that finite form can interrupt the continuous managerial space of urbanisation. Archigram’s nomadic systems displace architecture toward mobile services and temporary frameworks, revealing both the emancipatory and disciplinary potentials of flexibility. Spatial agency is thus neither contained within monumental objects nor dissolved into abstract flows. It is produced through thresholds, stoppages, routes and devices that regulate how bodies meet, move and separate. Benjamin and Friedlander reveal the archival form of the same operation. Historical fragments do not speak automatically; they acquire force through arrangement.
