4193 — The Primitive-Transfer Residual Is a Native Ternary Germ
After the source primitive transfers the relative Green response, the remaining common-path term on the normalized source fiber is
At the simultaneous seam origin, every unary and binary coordinate germ vanishes. The first nonzero derivative is
Equivalently, every two-dimensional face of the exact finite-difference cube is zero while the alternating three-cube difference is .
Thus the residual requires a direct ternary mate among spectral control, seam primitive, and common reciprocal path, or a binary factorization retaining the full three-instance carrier and associator. If source amplitude is varied, the raw term has arity four unless source multiplication is separately authorized.
