Wavefunction Correction: From Probability Amplitude to Measurement-Line Helix Trajectory v2.0

The standard quantum mechanical wavefunction Ψ(x,t) is treated as a probability amplitude — a mathematical description of knowledge, not a physical entity. Its complex phase, its spatial spread, and its lack of closure are all artifacts of treating measurement as an external operation. Within the World Quantum Theory (WQT) framework, this paper replaces the abstract wavefunction with the geometric trajectory of the measurement-line helix: Ψ_WQT(t) = r₀ · e^((b+i)θ(t)). This wavefunction directly describes the skeleton of the envelope interface — a closed, breathing, three-dimensional surface formed by the bending and closure of the measurement-line helix in a vortex field. The real part governs radial expansion; the imaginary part governs phase advancement; the modulus is locked to the speed of light c of the projection layer. This correction restores the wavefunction to a geometric entity, removes the need for probability interpretation, and provides a direct link to the envelope interface volume and breathing rate. The standard wavefunction is shown to be a projection of this helical trajectory onto a measurement axis, losing closure and geometric meaning in the process.
