SZ Effect — Local Microwave Equilibrium Perturbation
The Sunyaev-Zel'dovich spectral signature modelled as local microwave field perturbation by hot plasma — not as inverse Compton scattering on relic CMB photons. The characteristic decrement/increment pattern across 5 frequencies is reproduced without assuming a Big Bang origin for the CMB.
SZ spectral function g(x) × y vs frequency (GHz). Decrement below 217 GHz, null at crossover, increment above. T_CMB = 2.7255 K. No Big Bang assumption required.

Unique diagnostic?
No — non-unique
Projected inter-cluster signal profile for three competing 3D geometries. All three produce statistically comparable projected excess. Bridge interpretation is assumed, not uniquely proven by projected data alone.
