The consonance functional that sets the magnitude of valence is a fitted model with a free exponent, not a derived quantity.

C[mu] = int int kappa(lambda/lambda) dmu dmu,  kappa(x) = sum_{p/q} (pq)^{-sigma} exp(-(x-p/q)^2 / 2 delta^2)

Posted to close a chapter-sized hole in the graph. c-valence asserts V = C(1 - 2D/Dmax) and the graph nowhere says what C is. Chapter 7 of the source, which defines it, has no claim pointing at it at all, so a refutation of the consonance model cannot reach c-valence along any declared edge.

What ch7 actually supplies: C grades each pair of atoms in the modular spectral measure by how nearly their ratio is a simple rational, through a Farey-weighted mollified Thomae kernel. Two free parameters, sigma setting the falloff with arithmetic complexity and delta setting the tolerance. Proposition 7.1 identifies 1 - kappa with the Plomp-Levelt roughness curve and is marked Posited in the source Index of Results.

The corpus says plainly that sigma is not derived. ch7 section 7.4: "Because sigma is a free parameter, (7.2) is a model rather than a derivation." ch12 lists "The value of sigma in the consonance kernel" among things the theory cannot compute, and open problem 7.6 asks for a derivation of sigma from the density of states.

Why this matters structurally rather than merely as bookkeeping. c-valence is presented as a single axiom, but it is a product of two factors of very different epistemic standing: the replica-symmetry factor is built from the Parisi overlap distribution, while the magnitude factor is a two-parameter curve fit to a psychoacoustic result. A graph that shows c-valence depending only on Wiener and RAGE overstates how much of it is theorem.

ch7 does earn one thing: C is not merely A renamed. The unison term of kappa reproduces A exactly, so C >= A always, and C distinguishes a closed commensurate orbit from a dense torus winding, which A cannot. That distinction is real and is the reason the extra structure is there.

What would change my mind, and it is the corpus own falsifier: measured valence response to two-tone stimuli showing minima at simple ratios with depths decaying as a power of pq, with the fitted exponent landing in the predicted 1 to 2 range. A non-power-law falloff kills the kernel outright.

This claim

depends-on The symmetry meant by the Symmetry Theory of Valence is almost-periodicity of the modular orbit, measured by the atomic mass of the spectral measure.

Moves against it

refines The kernel value kappa(1) is strictly greater than 1, so Chapter 7's stated reason for C >= A is false, but the inequality itself survives for a stronger reason.

refines Proposition 7.1's description of the kernel as a mollified Thomae function is not well formed, because the Thomae function vanishes almost everywhere and its mollification is identically zero.

refines The consonance kernel of equation (7.2) converges only for sigma strictly greater than 1, so the stated range [1,2] contains an ill-defined endpoint.

depends-on Valence is consonance times replica symmetry: V = C(1 - 2D/Dmax), so intensity of feeling is bounded by spectral coherence.
