Evidence-Coupling Matrix

Canonical definition

Evidence-Coupling Matrix (KK). The Evidence-Coupling Matrix is the cross-Individual adjacency matrix K=[κij]K = [\kappa{ij}] governing the strength with which Individual jj's emitted Evidence proposition EtjEt^{j} enters Individual ii's Belief Register, with κij≥0\kappa{ij} \geq 0 for all i,ji, j. The diagonal κii=κself\kappa{ii} = \kappa{self} is the Self-Coupling Permanence term, which is strictly positive and structurally irreducible. The off-diagonal block KoffK{off} contains the interpersonal couplings, and its spectral radius ρ(Koff)\rho(K{off}) enters the network loop gain as GnetK=ρ(Koff)⋅∥∂ℓ/∂E∥⋅β ∥∂μ/∂b∥⋅ω(Tint)‾G{net}^{K} = \rho(K{off})\cdot \|\partial\ell/\partial E\|\cdot \beta\,\|\partial\mu/\partial b\|\cdot \overline{\omega(T{int})}.

Explanation

The Evidence-Coupling Matrix is the formal expression of Coupling Strength at the network scale. Where the scalar Coupling Strength describes a domain-level average, the Evidence-Coupling Matrix describes the directed, weighted, dyadic structure of who treats whom as a source of Evidence. The diagonal carries the Self-Coupling Permanence floor that no intervention can remove; the off-diagonal block carries the policy-modifiable interpersonal couplings whose spectral structure determines the network-scale Critical Coupling Strength. Patch-competent Evidence intake reduces the effective off-diagonal weights without altering the underlying graph topology, which is the fourth channel of the Knowledge Patch's network-scale formalisation.
