Stellar Gas Eigenvector Mass Probe

Status: SMN_EIGENVECTOR_MASS

Decision: ADMIT_SMN_EIGENVECTOR_MASS_HOLD_PHYSICAL_MASS

This probe computes the dominant covariance eigenvector over the coarse DESI epoviz to MaNGA population-cell join. The output is an SMN/evidence-load mass direction: it ranks the current coarse joined cells by this diagnostic score so later zoom work can choose explicit follow-up targets.

Claim boundary: this is not physical mass, not stellar mass, not a direct gas density map, and not a cosmology fit.
