Audit review

The paper’s Theorem 6.3 states that for a strongly proper expanding split sequence, the cone TM(X) of transverse measures is the inverse limit of levelwise nonnegative cones with bonding maps given by the transition matrices of the folds; the detailed proof in Chapter 6 proceeds via “edge weights,” “weight assignments,” and turn-transversal decompositions, and uses expansion to ensure non-atomicity and appropriate local product structures . The candidate model solution proves the same identification but via a slightly different construction based on flow boxes, clopen elementary transversals in fibers, and one-step holonomy, deriving the same compatibility relation w_{j-1}=M(f_j)w_j and the inverse construction. The only substantive gaps in the model sketch are routine technicalities: justifying that every compact transversal breaks into finitely many elementary pieces and clarifying the precise role of the expansion/non-atomicity hypothesis (the paper addresses these via Proposition 5.15 and its turn-based machinery) . Overall, both arguments are consistent and correct; the approaches differ in presentation and technical scaffolding, not in substance.

Referee report (LaTeX)

\textbf{Recommendation:} minor revisions

\textbf{Journal Tier:} specialist/solid

\textbf{Justification:}

The manuscript proves a central structural theorem: TM(X) is the inverse limit of nonnegative cones determined by transition matrices for a strongly proper expanding split sequence. The proof is correct and well-motivated, integrating the foliation viewpoint with combinatorics of folds. Minor clarifications (finite decomposability of transversals under expansion, explicit notes on when stabilization is used) would enhance accessibility and polish without changing results.
