This document presents a structural mapping of potential, distinction, definability limits, and collapse conditions. It outlines an architecture in which potential functions as the irreducible condition for any expression, and distinction operates as the sole mechanism through which potential takes form. The text demonstrates why “nothing” cannot be defined without collapsing into something, and why any structure requiring an outside, a before, or a definable nothing becomes self‑contradictory. The result is a complete, non‑regressive, non‑contradictory architecture that remains stable under its own constraints. Mapped by D.
