exact hG
/-- For a list `φs = φ₀…φₙ` of `𝓕.FieldOp`, a graded compliant Wick contraction `φsΛ` of `φs`,
and a `φ` in `𝓕.FieldOp`, the following relation holds
`(φsΛ ↩Λ φ 0 none).sign = φsΛ.sign`.
and a `φ` in `𝓕.FieldOp`, the following relation holds `(φsΛ ↩Λ φ 0 none).sign = φsΛ.sign`.
This is a direct corollary of `sign_insert_none`. -/
