The mass spectrum of the IIB flux landscape carries no geometric fingerprint

We test whether the mass spectrum of a flux vacuum carries a fingerprint pinning down the compactification. On 133 supersymmetric IIB flux vacua, the raw eigenvalues are predictable (ridge-on-quadratic CV r = 0.50-0.62) but the scale-invariant ratios are not (r < 0.25). The mass spectrum's shape is statistically uniform in flux — the fingerprint is not there — while its overall scale is flux-determined. This closes the 'masses carry the fingerprint' hypothesis.
