I spent the winter of 2024 redrawing every system I had built over the past decade. Not in code — in lines. Thin red lines for the connections that carry load, thin blue lines for the ones that flex. Sixty-four pages of crease patterns before I wrote a single function, and it changed how I think about architecture entirely.
The Problem with High Fidelity
Prototypes lie. A pixel-perfect mockup looks finished, but it hides the joints — the places where one module hands off to another, where a decision in one layer constrains three others downstream. I had been shipping systems that felt fragile in production for twelve years, and I finally understood why: I was designing surfaces, not structures.
The crease pattern discipline forced a different approach. Every fold has to be traceable from the sheet edge to the finished form. No hidden geometry, no magic creases that appear mid-fold. If a connection exists, it has a line on the diagram.
