Design as Event II — Persistence Field is the second public experimental phase of the Design as Event corpus. It proposes a computational and theoretical framework in which form is not treated as the effect of a privileged ratio, but as the outcome of persistence within a dynamic relational field. Structural significance is assigned to a cluster only when it demonstrates measurable endurance across scale, time, and perturbation. Persistence Field functions as the second live computational research instrument within the Design as Event sequence. In this phase, ratio-based locking is replaced by persistence-based topological evaluation, so that contour appears only as the secondary trace of a temporarily persistent relational configuration. This Zenodo record is intended as the stable archival counterpart of the public live node:https://design-walker.blogspot.com/2026/03/design-as-event-ii-persistence-field.html
