The (PITO, DIDO) phase plot — where the city sits, where it is moving.
A two-axis compression of the twenty-cell matrix. PITO on the horizontal — Products In, Trash Out, the linear-extractive metabolism. DIDO on the vertical — Data In, Data Out, the regenerative-distributed metabolism. Four cities plotted. Paris and Hamburg appear as reconstructed points from Utopies (2018) and Boeing (2024). Trajectory arrows show direction of travel toward the upper-left target regime.
The diagonal and the dynamic question
The single-number index — Boeing's 37/100, Utopies' 37.58/100 — corresponds to the city's distance from the lower-right corner measured along the diagonal. Once you accept that the diagonal terminus is set by global supply-chain geometry, the meaningful question is no longer the absolute score but the trajectory: where is the city moving in (PITO, DIDO) space, and how quickly does observation become action? The third axis ρ governs that velocity, and is what makes FCI 3.0 a metabolism rather than a snapshot.
