The Geometry of Administrative Amnesia: How Fiduciary Memory Disappeared and Why No Actor Could See It Happen

This paper reconstructs the structural process by which fiduciary memory — the knowledge of who granted authority and for whose benefit it must be exercised — disappeared from modern administrative systems without deliberate intent or identifiable breach. The disappearance is shown to be a geometric consequence of authority fragmentation, liability aggregation, and narrative substitution rather than a political choice. By tracing the transition from unified trustee identity to swarm-trustee perception, the paper demonstrates why no single institutional actor could perceive the total obligation field or recognise the loss of grantor memory as it occurred. The collapse of fiduciary recall is shown to be a necessary outcome of non-linear burden interaction and procedural decentralisation. Quadratic burden geometry is introduced as the formal mechanism by which reasonable local actions produce unreasonable global outcomes invisible to internal actors. Mimicry memory is identified as the structural substitute that permits continued operation while accelerating the underlying burden curvature. This paper is strictly diagnostic. It deliberately withholds any corrective operator, remedy, or external coordinate. Its purpose is to expose the geometry by which forgetting became structurally inevitable. A companion paper in the Fiduciary Manifold Series — The Grantor Invariant: A Field-Theoretic Restatement of Constitutional and Fiduciary Authority — addresses the geometry diagnosed here.
