Light is not a DNA-like helix in standard quantum electrodynamics. The photon is the quantized excitation of the electromagnetic field, and wave-particle duality is not explained by viewing a classical spiral from different directions. Nevertheless, helical and vortex-like optical modes are established physical objects in structured-light optics. Such modes carry orbital angular momentum, possess quantized phase winding, and can be generated and measured in classical and single-photon regimes. This manuscript uses that conservative fact as a testbed for the Helix-Light-Vortex (HLV) framework. We formulate a minimal helical optical mode model on a golden-angle G-lattice sampling, introduce a small spiral-time phase modulation, and report reproducible numerical diagnostics: winding recovery, detector-aperture response, quasicrystalline phase sampling, and modulation-induced interference signatures. The work does not claim to derive standard quantum mechanics, replace QED, or prove that biological DNA is a direct materialization of light. Its narrower claim is that structured helical light provides a physically legitimate analogue platform for testing HLV-style phase, memory, and discrete-geometry operators. The simulation files, tables, and figures are included for reproducibility.
