V.R397 — SLACS Einstein Radius Comparison

SLACS comparison: within θ_E (~5 kpc), total-to-stellar ratio is ~2-3 (most boundary holonomy mass at larger radii). At virial scale, ratio saturates at 6.65 — consistent with weak lensing measurements finding total-to-stellar ratios 5-8. Aperture-dependent mass ratio is a structural prediction of the τ-framework.
