In nonzero ambient holomorphic sectional curvature, the Gauss–soliton equation reconstructs the square P² of the tangential Kähler operator from the Hessian endomorphism and an extrinsic Ricci operator. Consequently, the PTR tangency spectrum is encoded by intrinsic soliton data together with the second fundamental form. For compact minimal PTR solitons with positive ambient curvature we obtain λ≤ c(n-1)/4, with a strict version under a relative-nullity condition. We also prove compact triviality criteria, an exact trace-free anisotropy identity, a parallel-data rigidity result, and a nonexistence theorem for compact real hypersurfaces. A flat multi-level Gaussian model and a nonflat Segre CR-product provide explicit consistency checks and identify the limiting cases of the reconstruction formulas.Ricci solitonsSphere theoremsKähler geometryStability & uniquenessEigenvalues & spectrum
