We derive the Kerr-Newman (KN) generalisation of the D3 information-geometry framework. Define σ = √ (1−χ²−q²). The master suppression factor is h (χ, q) = 4σ/ (2 (1+σ) −q²). The key identity σ²+χ²=1−q² collapses the KN denominator exactly, generalising the Paper 2 identity s²+χ²=1 to the charged case. All previous results are exact special cases: h (χ, 0) =f (χ) Paper 2, h (0, q) =g (q) Paper 6, h (0, 0) =1 Papers 1, 3. Total evaporation displacement Rₜotal (KN) =h (χ, q) ·rₛ exactly. Five constants cancel (M, ℏ, kB, ln2, π). The KN metric is the most general four-dimensional black hole — this is the most general result possible in the D3 framework. The series is complete.
