Two Early Fruits of Terrainism

The broader framework developed so far begins from a simple reversal: explanation should begin not with the agent in abstraction, but with the world the agent confronts. Terrainism makes this explicit by arguing that analysis should first classify the environment, then choose the lens, then measure, and only afterward intervene. Structural Economics sharpens the same move by treating the world as inherited, morphable terrain and by making deformation central: when terrain changes, accessibility changes. Fragility Economics then begins where Structural Economics stops. It asks how beings move through such a world when some paths threaten irreversible loss. This note presents two early fruits of that broader architecture in capital markets. Neither is offered here as a finished formal theory. The underlying mathematics is still under construction. The aim for now is more modest: to show that once one begins from terrain, deformation, survivability, and posture rather than from smooth optimization, two well-known puzzles in finance become easier to think about. The first fruit concerns portfolio construction under uncertainty. The second concerns the so-called low-risk anomaly. Both are partial. Both are philosophical before they are fully mathematical. But both are already logically downstream of the broader framework.
