Working paper proposing that twice-exceptional (2E) phenomenology constitutes an orthogonal dimension to the empirically observed ADHD↔ASD antipodal axis in the Ginzburg-Landau cortical field parameter space. Based on PCA of five GL observables (ξ, C1, C2, R, CV(C1)) computed from ABIDE I (n=554) and ADHD-200 Peking (n=81), the paper identifies PC2 (coherence length ξ) as the candidate orthogonal axis and proposes asymmetric modulation: compensatory in ADHD+2E, exacerbatory in ASD+2E. Eight falsifiable predictions are formulated, including a laminar clinical application.
