"""Term-family eigen probe for the full Standard Model Lagrangian wall.

The source image is a compact Standard Model Lagrangian expansion. A physical
eigenvector would require an explicit operator, basis, gauge fixing, background,
renormalization scale, and boundary conditions. This probe instead builds a
receipt-bearing feature operator from visible term families and computes the
principal eigenvector of that coupling/interaction matrix.
