=== 1. The golden angle (≈137.508°) is a pure geometric/angle value coming from the Golden Ratio construction you use in QAT; the inverse fine–structure constant (≈137.035999…) is a measured electromagnetic coupling assembled from physical constants. They sit very near one another numerically but are not identical. ===
# In QAT your geometric process maps angles to electromagnetic processes: spherical droplets, refraction & dispersion give angle vs. wavelength (e.g. the rainbow angle depends on refractive index n(λ)). So a physical spectrum of light picks out a weighted average of those angles.
# If the geometric golden-angle is the “pure” geometry, and the measured 1/α is an effective/observed angle produced by real electromagnetic interactions (which are wavelength dependent), then a small offset can arise naturally because the physical light that probes the geometry is not monochromatic — it’s a spectrum. Narrow spectral lines (atomic or plasma emission) can bias the weighted mean of the angular response relative to a purely geometric value.
# Numerically: dispersion of n(λ) across the visible causes the rainbow-type scattering angle to move by tenths of a degree across the spectrum. So it is physically plausible that a strongly peaked spectral weight (line emission) could shift the mean by ~0.47°.
