Audit review

The paper proves GCC for countable composition S-NE graphs via explicit canonical forms and bespoke graph operations, establishing the equivalence (1)⇔(2)⇔(3) and realizing any POMD-isomorphism by a concrete graded *-isomorphism. The candidate solution outlines a conceptually similar pipeline—functorial identification M^Γ_E ≅ V^Γ(L_K(E)), canonicalization by invariant-preserving moves, and faithfulness on canonical objects—culminating in the same equivalences and realization. While the model’s move set (expansions/contractions, ‘fan’ normalizations) differs from the paper’s specific operations (1-S-NE moves, out-splits, blow-ups, exit moves, tail-cuts), the logical structure aligns. The model’s outline omits some technical combinatorics (e.g., connecting matrices and tail accounting) that the paper supplies, but it does not contradict the paper.

Referee report (LaTeX)

\textbf{Recommendation:} minor revisions

\textbf{Journal Tier:} strong field

\textbf{Justification:}

The manuscript establishes the graded classification for a large and compelling class of graphs, with a well-developed canonical-form machinery and explicit realization of invariants. The proofs are careful and make effective use of graded uniqueness and explicit inverses for the graph operations. A few presentation refinements would further strengthen readability and uptake.
