Emergence XIV: Polarity as Primitive in the Emergence Model

This paper establishes that Polarity — the binary sign of the amplitude — is primitive in the Emergence model. Polarity \pi = \pm 1 is the engine of oscillation. Without polarity, there would be no rise and fall, no wave propagation, no pulsation of the time point. Polarity flips drive oscillation. The wave equation describes how these flips propagate. Polarity is the engine; the wave equation is the transmission. The paper distinguishes polarity from amplitude (magnitude), from electric charge (emergent), and from handedness (a separate primitive). It also draws an analogy with alternating current: polarity flips are the generator. This paper is a conceptual and foundational analysis, intended for readers interested in the structural assumptions of the Emergence model.
