 122/-! ## Part 2: Right-affine from polynomial consistency
 123
 124Combining `Inevitability.bilinear_family_forced` with the bilinear-implies-
 125right-affine lemma, we get: if `P` is a symmetric quadratic polynomial and `F`
 126satisfies the standard hypotheses, then `P` is right-affine.
 127
 128This means the `rightAffine` hypothesis in `FactorizationAssociativityGate` is
 129redundant under the stronger assumption that `P` is polynomial.
 130-/
 131
 132/-- Right-affine follows from polynomial consistency with a cost functional `F`.
 133
 134This theorem takes the Inevitability hypotheses (F normalized, consistent with
 135a symmetric quadratic polynomial P, non-trivial, continuous) and concludes
 136that P is right-affine. -/
