  core affine (n ≤ 15): p = -17.744, q = +6.0281 MeV · χ = φ⁻⁶ T₃ = 0.05573 T₃ = 0.4033 MeV (s1122 discriminator)
  ⁶He: pair above α = 0.9311 MeV (p9) ⇒ E_pair(1) = 1.7377 MeV after adding back the T=1 cost 0.8065
  ⁴²Ca datum: pair on 10 cells = 19.8435 MeV ⇒ c (per added cell) = 2.1014 MeV = 0.2904 T₃ · nearest menu member ½φ⁻¹T₃ = 2.2361 (+6.4%)

  [PASS] predictions produced for 8 + 8 blind nuclei, two variants each, without touching any blind row
  BARS for scoring (frozen): per line, signs of ΔB vs the N=Z neighbour correct; rms < 3 MeV; magnitude ratio of the excess-
  neutron energy (B − B_core) within [0.5, 2] at every A. Ca-calibrated 'cal' is the prediction; 'menu' is the registered-
  weight control. If 'cal' passes and 'menu' fails, the coupling is Loaded; if both pass, ½φ⁻¹T₃ is a candidate weight.
