Audit review
The paper proves the Lyapunov sum formula and the bad-locus dichotomy under Assumption A using analytic ‘steepness’/gradient-flow estimates (Theorem 2.2.8) and a uniformization of the domain of discontinuity via developing maps (Theorem 2.4.6), then plugs this into the EKMZ framework to conclude the formula (Remark 2.2.10). The candidate solution derives the Lyapunov sum via a Poincaré–Lelong/curvature argument on the reduced wedge W and identifies W^{0,4} ≅ V^{0,3} ⊗ V^{1,2}, and argues the bad-locus dichotomy via local Harish–Chandra normal form plus Schwarz–Pick/Yau. Both approaches are correct and yield the same conclusions, but the techniques are distinct.
Referee report (LaTeX)
\textbf{Recommendation:} minor revisions
\textbf{Journal Tier:} strong field
\textbf{Justification:}
The manuscript rigorously proves the EKMZ-predicted Lyapunov sum formula under Assumption A and gives a sharp bad-locus dichotomy, supplemented by uniformization results connecting Hodge theory and Anosov representations. The arguments are careful and largely self-contained. Minor editorial clarifications would enhance readability for a broad audience.
