=== A. Build the toy model numerically: compute spinor spherical harmonics, pick a simple holonomy phase ϕ(Ω)=ϕ0cos⁡θ\phi(\Omega)=\phi_0\cos\thetaϕ(Ω)=ϕ0cosθ (or a few simple modes), compute Mfi\mathcal{M}_{fi}Mfi and A_CP for realistic radii (fm and Å). Provide plots showing how A_CP depends on ϕ0\phi_0ϕ0 and r. ===
B. Derive an analytic leading-order estimate: show how a small holonomy ϕ\phiϕ produces A_CP ∝ φ times a geometric overlap integral (closed form), and plug in numbers to see whether tiny φ of order 10⁻? could produce observed CP asymmetries.
C. Write the boundary action carefully with explicit SU(2)×U(1) couplings, integrate out heavy bosons to get an effective 4-fermion operator localized on S², and show the exact expression for Mfi\mathcal{M}_{fi}Mfi in mode language (this is the full field-theory derivation).

Tell me which you prefer. I recommend A or B first — they give immediate intuition and numbers.
