V.R417 — Cross-Theme Consistency

Wave 23 cross-theme consistency: Theme A (shadow polarimetry), Theme B (jet physics), Theme C (cosmic web) all derive from same topological invariant genus(T²)=1. B_tor/B_pol=ι_τ⁻¹ connects shadow (V.T230), jet base (V.P156), and filament alignment (V.D292). No free parameters across all three scales.
